Industry Overview

        Tetra Tech is part of the global consulting and engineering industry that serves public and private clients by addressing the fundamental needs for water, natural resources, environmental services, infrastructure and energy. Our industry provides clients with the technical studies, planning, engineering, design and construction management services that address their needs. The industry's clients vary in size and scope from small local public agencies and private companies to national governments and large multi-national corporations. These clients seek service firms with high-caliber technical expertise, practical experience, multi-disciplinary capabilities and a global reach to analyze their problems and develop and implement the most appropriate, cost-effective solutions.

        Many government and commercial organizations today face new, complex challenges due to increased demand and competition for water and natural resources, newly understood threats to human health and the environment, aging infrastructure, and a desire to diversify energy resources. As a global company, we provide the breadth of technical knowledge and capabilities and the global reach to address our clients' needs in the areas of water, natural resources, the environment, infrastructure and energy. We work for a wide variety of clients to solve diverse and challenging problems. Our water market consists primarily of government agencies that are responsible for managing water resources in a given area, including large regional planning studies and local water treatment and wastewater services. For commercial clients, we support the development of water supplies and management of water to help meet federal and local government requirements and policies. We provide essential support for water and site management needs for resource extraction in the mining and oil and gas industries. Our environmental market consists of both government and commercial clients that are working to comply with environmental regulations, restore contaminated areas and protect uncontaminated areas. Our infrastructure market includes the design of public and commercial buildings and facilities, including high-performance buildings. Our energy market consists of both government and commercial clients that are developing renewable energy resources, energy efficiency improvements or energy transmission projects.

        Increasingly, the consulting and engineering industry is being asked to provide integrated solutions in a global marketplace. Large firms such as Tetra Tech can offer fully integrated services, from front-end science and planning through construction management. Large firms that offer integrated solutions differentiate themselves from smaller firms that generally offer niche services by providing turn-key solutions intended to save time and money.

        Many scientific discoveries and public policy forces are now shaping changes in our industry. Public concern over environmental issues, especially water quality, has been a driving force behind numerous regulations and changes in public policies and practices. Our government and commercial clients are increasingly focused on environmental stewardship, infrastructure needs, energy efficiency and sustainability as part of their programs. Fluctuations in weather patterns and extreme events, such as droughts or flooding, are driving concerns over the reliability of water supplies and the need to protect coastal areas and upgrade water infrastructure. Energy policies, resource limitations and concern over climate change have encouraged rapid implementation of energy conservation measures, retrofits of existing structures, upgrades to transmission infrastructure and the development of renewable energy resources. Many governments of developed countries are now implementing international development as a foreign policy tool to assist developing nations in conjunction with diplomacy and defense. We support international development by providing in-country assistance in making water supplies accessible, protecting human health, supplying emergency humanitarian assistance and enhancing the ability of government institutions to implement these changes.


The Tetra Tech Strategy

        To continue our successful growth and maintain a competitive position, we have implemented the following strategy that is integral to our future growth:

        Start with Science.    We typically start with science at the onset of a project, building on our staff's strong technical foundation in natural and physical sciences.

        Provide Broad Geographic Coverage and Local Expertise.    We believe that proximity to our clients is instrumental to understanding their needs and delivering comprehensive services. We have significantly broadened our geographic presence in recent years through strategic acquisitions and internal growth. We currently have North American operations throughout the United States and Canada. We have also increased our international presence with regional offices in Europe, Asia, South America, Australia, Africa and the Middle East. Our base of operations in North America and network of international offices provide a platform from which we can respond to the global need for responsible economic development and management, while ensuring that communities have access to basic services in a secure environment. We are actively working in more than 60 countries in support of the U.S. government, the private sector and development assistance agencies to address complex infrastructure and environmental challenges in an environmentally responsible manner.

        Leverage Existing Client Base.    We believe that we can effectively expand our service offerings to existing clients, resulting in more comprehensive services and, ultimately, increases in our revenue. Often, we have been able to secure construction management contracts after having served clients on

Our interdisciplinary capabilities in water, natural resources, the environment, energy and infrastructure provide the opportunity to develop integrated and sustainable solutions. Our combination of technical expertise with practical applications provides challenging and rewarding opportunities for our employees, thereby enhancing our ability to serve other public and commercial clients.

        Focus on Cash Generation.    We take a disciplined approach to monitoring, managing and improving our return on investment in each of our business areas through our efforts to negotiate appropriate contract terms, manage our contract performance to minimize schedule delays and cost overruns, and promptly bill and collect accounts receivable.

        Actively Attract, Recruit and Retain Strategic Hires.    We focus on attracting and retaining top-quality individuals who provide technical skills, innovative solutions and long-term client relationships. Our full-service capabilities, internal coordination and networking opportunities, entrepreneurial environment, focus on technical excellence and global project portfolio help to attract and retain highly qualified individuals who support our long-term growth.

        Invest in Strategic Acquisitions.    We believe that strategic acquisitions will allow us to continue our growth in selected business areas, broaden our service offerings and extend our geographic presence. We intend to make acquisitions that will enable us to strengthen our position in certain emerging business areas or further strengthen our position in our more established service offerings. We believe that our reputation makes us an attractive partner. Our effective integration of acquisitions can continue to enhance our ability to compete technically and geographically.

Contracts

        Our services are performed under three principal types of contracts with our clients: fixed-price, time-and-materials, and cost-plus. The following table presents the percentage of our revenue by contract type:

 
  Fiscal Year
 
  2010   2009   2008
Contract Type    
   
   
  
   
   
   

Fixed-price

    42.0%     40.8%     38.0%

Time-and-materials

    34.0         37.2         37.9    

Cost-plus

    24.0         22.0         24.1    
             

  100.0%   100.0%   100.0%
             

        Our clients select the type of contract we enter into for a particular engagement. Under a fixed-price contract, the client agrees to pay a specified price for our performance of the entire contract or a specified portion of the contract. Some fixed-price contracts can include date-certain and/or performance obligations. Fixed-price contracts carry certain inherent risks, including risks of losses from underestimating costs, delays in project completion, problems with new technologies, price increases for materials, and economic and other changes that may occur over the contract period. Consequently, the profitability, if any, of fixed-price contracts may vary substantially. Under our time-and-materials contracts, we are paid for labor at negotiated hourly billing rates and for other expenses. Profitability on these contracts is driven by billable headcount and cost control. Many of our time-and-materials contracts are subject to maximum contract values and, accordingly, revenue related to these contracts is recognized as if these contracts were fixed-price contracts. Under our cost-plus contracts, we are reimbursed for allowable costs and fees, which may be fixed or performance-based. If our costs exceed the contract ceiling or are not allowable, we may not be able to obtain full reimbursement. Further, the amount of the fee received for a cost-plus award fee contract partially depends upon the client's discretionary periodic assessment of our performance on that contract.

        Some contracts with the U.S. federal government are subject to annual funding approval. U.S. federal government agencies may impose spending restrictions that limit the continued funding of our existing contracts and may limit our ability to obtain additional contracts. These limitations, if significant, could have a material adverse effect on us. All contracts with the U.S. federal government may be terminated by the government at any time, with or without cause.

        U.S. federal government agencies have formal policies against continuing or awarding contracts that would create actual or potential conflicts of interest with other activities of a contractor. These policies may prevent us from bidding for or performing government contracts resulting from or related to certain work we have performed. In addition, services performed for a commercial or government sector client may create conflicts of interest that preclude or limit our ability to obtain work for a private organization. We attempt to identify actual or potential conflicts of interest and to minimize the possibility that such conflicts could affect our work under current contracts or our ability to compete for future contracts. We have, on occasion, declined to bid on a project because of an existing or potential conflict of interest.

        Our contracts with the U.S. federal government are subject to audit by the government, primarily by the Defense Contract Audit Agency ("DCAA"). The DCAA generally seeks to (i) identify and evaluate all activities that contribute to, or have an impact on, proposed or incurred costs of government contracts; (ii) evaluate a contractor's policies, procedures, controls and performance; and (iii) prevent or avoid wasteful, careless and inefficient production or service. To accomplish this, the

17


Table of Contents


DCAA examines our internal control systems, management policies and financial capability; evaluates the accuracy, reliability and reasonableness of our cost representations and records; and assesses our compliance with Cost Accounting Standards ("CAS") and defective-pricing clauses found within the Federal Acquisition Regulation ("FAR"). The DCAA also performs an annual review of our overhead rates and assists in the establishment of our final rates. This review focuses on the allowability of cost items and the applicability of CAS. The DCAA also audits cost-based contracts, including the close-out of those contracts.

        The DCAA reviews all types of U.S. federal government proposals, including those of award, administration, modification and re-pricing. The DCAA considers our cost accounting system, estimating methods and procedures, and specific proposal requirements. Operational audits are also performed by the DCAA. A review of our operations at every major organizational level is conducted during the proposal review period. During the course of its audit, the U.S. federal government may disallow costs if it determines that we accounted for such costs in a manner inconsistent with CAS. Under a government contract, only those costs that are reasonable, allocable and allowable are recoverable. A disallowance of costs by the U.S. federal government could have a material adverse effect on us.

        In accordance with our corporate policies, we maintain controls to minimize any occurrence of fraud or other unlawful activities that could result in severe legal remedies, including the payment of damages and/or penalties, criminal and civil sanctions, and debarment. In addition, we maintain preventative audit programs and mitigation measures to ensure that appropriate control systems are in place.

        We provide our services under contracts, purchase orders or retainer letters. Our policy provides that all contracts must be in writing. We bill our clients in accordance with the contract terms and periodically based on costs incurred, on either an hourly-fee basis or on a percentage-of-completion basis, as the project progresses. Most of our agreements permit our clients to terminate the agreements without cause upon payment of fees and expenses through the date of the termination. Generally, our contracts do not require that we provide performance bonds. If required, a performance bond, issued by a surety company, guarantees a contractor's performance under the contract. If the contractor defaults under the contract, the surety will, at its discretion, complete the job or pay the client the amount of the bond. If the contractor does not have a performance bond and defaults in the performance of a contract, the contractor is responsible for all damages resulting from the breach of contract. These damages include the cost of completion, together with possible consequential damages such as lost profits.


Marketing and Business Development

        Our corporate management team establishes the scope and range of services we provide and our overall business strategy. The centralized business development support group develops corporate marketing materials, conducts market research, and manages promotional and professional activities, including appearances at trade shows, direct mailings, advertising and public relations. Business development activities are implemented by our technical and professional management staff. We believe that these personnel have the best understanding of a client's needs and the effect of local or client-specific issues, laws and regulations. Our professional staff members hold frequent meetings with existing and potential clients, and federal, state or local government agencies; give presentations to civic and professional organizations; and present seminars on current technical topics. Essential to the effective development of business is each staff member's access to all of our service offerings through the technical and geographic network we provide. We facilitate a strong internal network that allows our professional staff members to recognize opportunities to provide new services to existing clients and broaden our client base in core services. We market throughout the client organizations we target, focusing on delivering solutions to emerging programs and providing full-service support.

Table of Contents

        For our major focus areas, we have established company-wide initiatives that reinforce internal coordination across the enterprise, track the development of new programs, identify and coordinate collective resources for major bids, and build interdisciplinary teams. These initiatives provide a forum for cross-sector collaboration and the development of interdisciplinary solutions. We continuously identify new markets that are consistent with our service offerings and leverage our full-service capabilities and internal coordination structure to develop and implement strategies to research, anticipate and position for future procurements.


Sustainability Program

        We lead and support programs that minimize our collective impacts on the environment through the solutions we provide for our clients ("Projects"), through our procurement and subcontracting approach ("Procurement"), and with internal policies and processes that promote sustainable practices, reduce costs and minimize environmental impacts ("Processes"). Collectively, we identify these three sustainability areas as the "3 Ps" that form the pillars of our Sustainability Program. Consistent with the Global Reporting Initiative's internationally recognized sustainability reporting guidelines, we have established a clear set of metrics that define our sustainability goals. We continuously implement sustainability policies and practices, and assess the results of our efforts in order to improve upon them in the future.

        Our Sustainability Program is led by our Chief Sustainability Officer, who has been appointed by executive management and is supported by other key corporate stakeholders via our sustainability council. Our executive management team reviews and approves the Sustainability Program and evaluates our progress in achieving the goals and objectives outlined in our plan. We publish a periodic sustainability report that documents our progress.


Acquisitions

        We continuously evaluate the marketplace for strategic acquisition opportunities. Due to our reputation, size, financial resources, geographic presence and range of services, we have numerous opportunities to acquire privately and publicly held companies or selected portions of such companies. During our evaluation, we examine the effect an acquisition may have on our long-range business strategy and results of operations. Generally, we proceed with an acquisition if we believe that it would have a positive effect on future operations and could strategically expand our service offerings. As successful integration and implementation are essential to achieving favorable results, no assurance can be given that all acquisitions will provide accretive results. Our strategy is to position ourselves to address existing and emerging markets. We view acquisitions as a key component of our growth strategy, and we intend to use cash, debt or securities as we deem appropriate, to fund acquisitions. We may acquire other businesses that we believe are synergistic and will ultimately increase our revenue and net income, strengthen our ability to achieve our strategic goals, provide critical mass with existing clients and further expand our lines of service. We typically pay a purchase price that results in the recognition of goodwill, generally representing the intangible value of a successful business with an assembled workforce specialized in our areas of interest. Acquisitions are inherently risky, and no assurance can be given that our previous or future acquisitions will be successful or will not have a material adverse effect on our financial position, results of operations or cash flow. All acquisitions require the approval of our Board of Directors, and those in excess of a certain size require the approval of our lenders.

        In fiscal 2007, we acquired Delaney Construction Corporation ("DGI"), which provides planning, development and construction services for wind energy programs, BRAC projects, and water and wastewater treatment and conveyance facilities to its broad-based clients. This acquisition enabled us to provide a wider range of services to our current and prospective wind energy clients, as DGI offers complementary capabilities and client relationships. In fiscal 2008, we acquired ARD, Inc. ("ARD"),

19


Table of Contents


which provides applied research, planning, design and implementation services focused on a range of water, energy, environmental and governance challenges. ARD manages large, complex international development projects for its clients, predominantly USAID. This acquisition increased our professional workforce in new geographic areas and technical specialties around the world. In fiscal 2009, we acquired Wardrop Engineering, Inc. ("Wardrop"), a Canadian firm that specializes in resource management, energy and infrastructure design. This acquisition significantly expanded our worldwide presence with offices throughout Canada, and in the United Kingdom and India. In fiscal 2010, we acquired EBA Engineering Consultants, Ltd. ("EBA"), a Canadian firm that provides natural science, engineering and arctic engineering services to the mining, energy and infrastructure sectors. This acquisition strengthened our geographic presence, and added new customers and complementary technical services. Since fiscal 2006, we also made other acquisitions that enhanced our service offerings to broad-based clients and expanded our geographic presence.


Competition

        The market for our services is generally highly competitive. We often compete with many other firms ranging from small regional firms to large international firms.

        We perform a broad spectrum of consulting, engineering and technical services across our reportable segments. Our client base includes U.S. federal government agencies, such as the DoD, USAID, DOE, EPA, NASA and FAA; state and local government agencies; the commercial sector; and international clients. Our competition varies and is a function of the business areas in which, and client sectors for which, we perform our services. The number of competitors for any procurement can vary widely, depending upon technical qualifications, the relative value of the project, geographic location, the financial terms and risks associated with the work, and any restrictions placed upon competition by the client. Historically, clients have chosen among competing firms by weighing the quality, innovation and timeliness of the firm's service versus its cost to determine which firm offers the best value. When less work becomes available in a given market, price becomes an increasingly important factor.

        We believe that our principal competitors include the following firms, in alphabetical order: AECOM Technology Corporation; AMEC PLC; Arcadis NV; Black & Veatch Corporation; Brown & Caldwell; CH2M Hill Companies Ltd.; Camp Dresser & McKee, Inc.; Chemonics International Inc.; Dessau, Inc.; GENIVAR; ICF International, Inc.; Jacobs Engineering Group, Inc.; MWH Global, Inc.; Science Applications International Corporation; The Shaw Group, Inc.; SNC-Lavalin Group, Inc.; Stantec, Inc.; TRC Companies, Inc.; URS Corporation; and Weston Solutions, Inc.


Backlog

        We include in our backlog only those contracts for which funding has been provided and work authorization has been received. We estimate that approximately 75% of our backlog as of fiscal 2010 year-end will be recognized as revenue in fiscal 2011, as work is performed. However, we cannot guarantee that the revenue projected in our backlog will be realized or, if realized, will result in profits. In addition, project cancellations or scope adjustments may occur with respect to contracts reflected in our backlog. For example, certain of our contracts with the U.S. federal government and other clients are terminable at the discretion of the client, with or without cause. These types of backlog reductions could adversely affect our revenue and margins. Accordingly, our backlog as of any particular date is an uncertain indicator of our future earnings.

        As of fiscal 2010 year-end, our backlog was $1.9 billion, an increase of 17.1% compared to fiscal 2009 year-end. Our backlog growth was driven by our fiscal 2010 acquisitions and increased funding on U.S. federal government programs, including those administered by USAID, DOE and EPA, and new orders from our international clients, particularly for our international mining services.

Regulations

        We engage in various service activities that are subject to government oversight, including environmental laws and regulations, general government procurement laws and regulations, and other regulations and requirements imposed by specific government agencies with which we conduct business.

        Environmental.    A substantial portion of our business involves planning, design, program management and construction management of pollution control facilities, as well as assessment and management of remediation activities at hazardous waste or Superfund sites and military bases. In addition, we contract with U.S. federal government entities to destroy hazardous materials, including weapons stockpiles. These activities require us to manage, handle, remove, treat, transport and dispose of toxic or hazardous substances.

        Some environmental laws, such as the Superfund law and similar state statutes, can impose liability for the entire cost of clean-up for contaminated facilities or sites upon present and former owners and operators, as well as generators, transporters and persons arranging for the treatment or disposal of such substances. In addition, while we strive to handle hazardous and toxic substances with care and in accordance with safe methods, the possibility of accidents, leaks, spills and the events of force majeure always exist. Humans exposed to these materials, including workers or subcontractors engaged in the transportation and disposal of hazardous materials and persons in affected areas, may be injured or become ill, resulting in lawsuits that expose us to liability that may result in substantial damage awards. Liabilities for contamination or human exposure to hazardous or toxic materials, or a failure to comply with applicable regulations, could result in substantial costs, including clean-up costs, fines, civil or criminal sanctions, third party claims for property damage or personal injury, or cessation of remediation activities.

        Certain of our business operations are covered by Public Law 85-804, which provides for government indemnification against claims and damages arising out of unusually hazardous activities performed at the request of the government. Due to changes in public policies and law, however, government indemnification may not be available in the case of any future claims or liabilities relating to other hazardous activities that we perform.

        Government Procurement.    The services we provide to the U.S. federal government are subject to FAR and other rules and regulations applicable to government contracts. These rules and regulations:

    Require certification and disclosure of all cost and pricing data in connection with the contract negotiations under certain contract types;

    Impose accounting rules that define allowable and unallowable costs and otherwise govern our right to reimbursement under certain cost-based government contracts; and

    Restrict the use and dissemination of information classified for national security purposes and the exportation of certain products and technical data.

        In addition, services provided to the DoD are monitored by the Defense Contract Management Agency and audited by the DCAA. Our government clients can also terminate any of their contracts, and many of our government contracts are subject to renewal or extension annually.

21


Table of Contents


Seasonality

        We experience seasonal trends in our business. Our revenue is typically lower in the first half of our fiscal year, primarily due to the Thanksgiving, Christmas and New Year's holidays. Many of our clients' employees, as well as our own employees, take vacations during these holiday periods. Further, seasonal inclement weather conditions occasionally cause some of our offices to close temporarily or may hamper our project field work. These occurrences result in fewer billable hours worked on projects and, correspondingly, less revenue recognized. Our revenue is typically higher in the second half of the fiscal year due to favorable weather conditions during spring and summer months that may result in higher billable hours. In addition, our revenue is typically higher in the fourth fiscal quarter due to the U.S. federal government's fiscal year-end spending.


Potential Liability and Insurance

        Our business activities could expose us to potential liability under various environmental laws and under workplace health and safety regulations. In addition, we occasionally assume liability by contract under indemnification agreements. We cannot predict the magnitude of such potential liabilities.

        We maintain a comprehensive general liability policy with an umbrella policy that covers losses beyond the general liability limits. We also maintain professional errors and omissions liability and contractor's pollution liability insurance policies. We believe that both policies provide adequate coverage for our business. When we perform higher-risk work, such as fixed-price remediation with insurance or UXO services, we obtain the necessary types of insurance coverages for such activities, as is typically required by our clients.

        We obtain insurance coverage through a broker that is experienced in the professional liability field. The broker and our risk manager regularly review the adequacy of our insurance coverage. Because there are various exclusions and retentions under our policies, or an insurance carrier may become insolvent, there can be no assurance that all potential liabilities will be covered by our insurance policies or paid by our carrier.

        We evaluate the risk associated with claims. If we determine that a loss is probable and reasonably estimable, we establish an appropriate reserve. A reserve is not established if we determine that a claim has no merit or is not probable or reasonably estimable. Our historic levels of insurance coverage and reserves have been adequate. However, partially or completely uninsured claims, if successful and of significant magnitude, could have a material adverse effect on our business.


Employees

        Our principal asset is our employees. We currently have approximately 12,000 employees, and a large percentage of our employees have technical and professional backgrounds and undergraduate and/or advanced degrees, including the employees of recently acquired companies. Our professional staff includes archaeologists, architects, biologists, chemical engineers, chemists, civil engineers, computer scientists, economists, electrical engineers, environmental engineers, environmental scientists, geologists, hydrogeologists, mechanical engineers, oceanographers, project managers and toxicologists. Approximately 211 employees are represented by labor unions pursuant to collective bargaining agreements. We consider the relationships with our employees to be favorable. We believe that our ability to retain and expand our staff of qualified professionals will be an important factor in determining our future growth and success. To date, we believe that we have been successful in recruiting and retaining qualified employees, and we are not aware of any circumstances that are likely to result in a work stoppage at any of our facilities. On certain engagements, we supplement our consultants with independent contractors. We believe that the practice of retaining independent contractors on an engagement basis provides us with significant flexibility in adjusting professional personnel levels in response to changes in demand for our services.

Item 1A.   Risk Factors

        Set forth below and elsewhere in this report and in other documents we file with the SEC are descriptions of the risks and uncertainties that could cause our actual results to differ materially from the results contemplated by the forward-looking statements contained in this report.

Our operating results may be adversely impacted by worldwide political and economic uncertainties and specific conditions in the markets we address.

        General worldwide economic conditions have experienced a downturn due to the lack of available credit, slower economic activity, concerns about inflation and deflation, increased energy costs, decreased consumer confidence, reduced corporate profits and capital spending, and adverse business conditions. These conditions make it extremely difficult for our clients and our vendors to accurately forecast and plan future business activities and could cause businesses to slow spending on services, and they have also made it very difficult for us to predict the short-term and long-term impacts on our business. We cannot predict the timing, strength or duration of any economic slowdown or subsequent economic recovery worldwide or in our industry. If the economy or markets in which we operate deteriorate from the level experienced in fiscal 2010, our business, financial condition and results of operations may be materially and adversely affected.

Our annual revenue, expenses and operating results may fluctuate significantly, which may adversely affect our stock price.

        Our annual revenue, expenses and operating results may fluctuate significantly because of numerous factors, some of which may contribute to more pronounced fluctuations in an uncertain global economic environment. These factors include:

    General economic or political conditions;

    Unanticipated changes in contract performance that may affect profitability, particularly with contracts that are fixed-price or have funding limits;

    Seasonality of the spending cycle of our public sector clients, notably the U.S. federal government, the spending patterns of our commercial sector clients, and weather conditions;

    Budget constraints experienced by our federal, state and local government clients;

    Integration of acquired companies;

    Changes in contingent consideration related to acquisition earn-outs;

    Divestiture or discontinuance of operating units;

    Employee hiring, utilization and turnover rates;

    Loss of key employees;

    The number and significance of client contracts commenced and completed during a quarter;

    Creditworthiness and solvency of clients;

    The ability of our clients to terminate contracts without penalties;

    Delays incurred in connection with a contract;

    The size, scope and payment terms of contracts;

    Contract negotiations on change orders and collections of related accounts receivable;

    The timing of expenses incurred for corporate initiatives;

28


Table of Contents

    Reductions in the prices of services offered by our competitors;

    Threatened or pending litigation;

    Legislative and regulatory enforcement policy changes that may affect demand for our services;

    The impairment of goodwill or identifiable intangible assets;

    The fluctuation of a foreign currency exchange rate;

    Stock-based compensation expense;

    Actual events, circumstances, outcomes and amounts differing from judgments, assumptions and estimates used in determining the value of certain assets (including the amounts of related valuation allowances), liabilities and other items reflected in our consolidated financial statements;

    How well we execute our strategy and operating plans; and

    Changes in tax laws or regulations or accounting rules.

        As a consequence, operating results for a particular future period are difficult to predict and, therefore, prior results are not necessarily indicative of results to be expected in future periods. Any of the foregoing factors, or any other factors discussed elsewhere herein, could have a material adverse effect on our business, results of operations and financial condition that could adversely affect our stock price.

Demand from our state and local government and commercial clients is cyclical and vulnerable to economic downturns. If the economy remains weak or client spending declines further, then our revenue, profits and our financial condition may deteriorate.

        Demand for services from our state and local government and commercial clients is cyclical and vulnerable to economic downturns, which may result in clients delaying, curtailing or canceling proposed and existing projects. Our business traditionally lags the overall recovery in the economy; therefore, our business may not recover immediately when the economy improves. If the economy remains weak or client spending declines further, then our revenue, profits and overall financial condition may deteriorate. Our state and local government clients may face budget deficits that prohibit them from funding new or existing projects. In addition, our existing and potential clients may either postpone entering into new contracts or request price concessions. Difficult financing and economic conditions may cause some of our clients to demand better pricing terms or delay payments for services we perform, thereby increasing the average number of days our receivables are outstanding and the potential of increased credit losses of uncollectible invoices. Further, these conditions may result in the inability of some of our clients to pay us for services that we have already performed. If we are not able to reduce our costs quickly enough to respond to the revenue decline from these clients, our operating results may be adversely affected. Accordingly, these factors affect our ability to forecast our future revenue and earnings from business areas that may be adversely impacted by market conditions.

Our revenue from commercial clients is significant, and the credit risks associated with certain of these clients could adversely affect our operating results.

        In fiscal 2010, we generated 23.8% of our revenue from commercial clients. Due to continuing weakness in general economic conditions, our commercial business may be at risk as we rely upon the financial stability and creditworthiness of our clients. To the extent the credit quality of these clients deteriorates or these clients seek bankruptcy protection, our ability to collect our receivables, and ultimately our operating results, may be adversely affected.

We derive a majority of our revenue from government agencies, and any disruption in government funding or in our relationship with those agencies could adversely affect our business.

        In fiscal 2010, we generated 66.7% of our revenue from contracts with U.S. federal, state and local government agencies. U.S. federal government agencies are among our most significant clients. We generated 51.9% of our revenue for fiscal 2010 from the following agencies: 28.6% from DoD agencies, 11.4% from USAID and 11.9% from other U.S. federal government agencies. A significant amount of this revenue is derived under multi-year contracts, many of which are appropriated on an annual basis. As a result, at the beginning of a project, the related contract may be only partially funded, and additional funding is normally committed only as appropriations are made in each subsequent year. These appropriations, and the timing of payment of appropriated amounts, may be influenced by numerous factors as noted below. Our backlog includes only the projects that have funding appropriated.

        The demand for our government-related services is generally driven by the level of government program funding. Accordingly, the success and further development of our business depends, in large part, upon the continued funding of these government programs, and upon our ability to obtain contracts and perform well under these programs. There are several factors that could materially affect our government contracting business, including the following:

    Changes in and delays or cancellations of government programs, requirements or appropriations;

    Budget constraints or policy changes resulting in delay or curtailment of expenditures related to the services we provide;

    Re-competes of government contracts;

    The timing and amount of tax revenue received by federal, state and local governments, and the overall level of government expenditures;

    Curtailment in the use of government contracting firms;

    Delays associated with insufficient numbers of government staff to oversee contracts;

    The increasing preference by government agencies for contracting with small and disadvantaged businesses;

    Competing political priorities and changes in the political climate with regard to the funding or operation of the services we provide;

    The adoption of new laws or regulations affecting our contracting relationships with the federal, state or local governments;

    Unsatisfactory performance on government contracts by us or one of our subcontractors, negative government audits, or other events that may impair our relationship with the federal, state or local governments;

    A dispute with or improper activity by any of our subcontractors; and

    General economic or political conditions.

        These and other factors could cause government agencies to delay or cancel programs, to reduce their orders under existing contracts, to exercise their rights to terminate contracts or not to exercise contract options for renewals or extensions. Any of these actions could have a material adverse effect on our revenue or timing of contract payments from these agencies.

A significant shift in U.S. defense spending could harm our operations and significantly reduce our profits and revenue.

        In fiscal 2010, we generated 28.6% of our revenue from the DoD agencies. We continued to experience a revenue decline due to the completion of our Iraq-related contracts, largely offset by BRAC and other domestic programs with the DoD agencies. Past increases in spending for defense-related programs and outsourcing of U.S. federal government jobs to the private sector are not expected to be sustained on a long-term basis. Future levels of expenditures and authorizations for defense-related programs may decrease, remain constant or shift to other programs in areas in which we do not currently provide services. As a result, a general decline in U.S. defense spending or a change in budgetary priorities could reduce our profits and revenue.

A delay in the completion of the budget process of the U.S. government could delay procurement of our services and have an adverse effect on our future revenue.

        When the U.S. government does not complete its budget process before its fiscal year-end on September 30, government operations are typically funded by means of a continuing resolution that authorizes agencies of the U.S. government to continue to operate but does not authorize new spending initiatives. When the U.S. government operates under a continuing resolution, government agencies may delay the procurement of services, which could reduce our future revenue.

As a government contractor, we must comply with various procurement laws and regulations and are subject to regular government audits; a violation of any of these laws and regulations or the failure to pass a government audit could result in sanctions, contract termination, forfeiture of profit, harm to our reputation or loss of our status as an eligible government contractor and could reduce our profits and revenue.

        We must comply with and are affected by U.S. federal, state, local and foreign laws and regulations relating to the formation, administration and performance of government contracts. For example, we must comply with FAR, the Truth in Negotiations Act, CAS, the American Recovery and Reinvestment Act of 2009 ("ARRA"), the Services Contract Act and DoD security regulations, as well as many other rules and regulations. In addition, we must also comply with other government regulations related to employment practices, environmental protection, health and safety, tax, accounting and anti-fraud measures, as well as many others regulations in order to maintain our government contractor status. These laws and regulations affect how we do business with our clients and, in some instances, impose additional costs on our business operations. Although we take precautions to prevent and deter fraud, misconduct and non-compliance, we face the risk that our employees or outside partners may engage in misconduct, fraud or other improper activities. Government agencies, such as the DCAA, routinely audit and investigate government contractors. These government agencies review and audit a government contractor's performance under its contracts and cost structure, and evaluate compliance with applicable laws, regulations and standards. In addition, during the course of its audits, the DCAA may question our incurred project costs. If the DCAA believes we have accounted for such costs in a manner inconsistent with the requirements for FAR or CAS, the DCAA auditor may recommend to our U.S. government corporate administrative contracting officer to disallow such costs. Historically, we have not experienced significant disallowed costs as a result of government audits. However, we can provide no assurance that the DCAA or other government audits will not result in material disallowance for incurred costs in the future. In addition, government contracts are subject to a variety of other requirements relating to the formation, administration, performance and accounting for these contracts. We may also be subject to qui tam litigation brought by private individuals on behalf of the government under the Federal Civil False Claims Act, which could include claims for treble damages. Government contract violations could result in the imposition of civil and criminal penalties or sanctions, contract termination, forfeiture of profit and/or suspension of payment, any of which could make us lose our status as an eligible government contractor. We could also suffer serious harm to our

31


Table of Contents


reputation. Any interruption or termination of our government contractor status could reduce our profits and revenue significantly.

Our inability to win or renew government contracts during regulated procurement processes could harm our operations and significantly reduce or eliminate our profits.

        Government contracts are awarded through a regulated procurement process. The U.S. federal government has increasingly relied upon multi-year contracts with pre-established terms and conditions, such as indefinite delivery/indefinite quantity ("IDIQ") contracts, which generally require those contractors who have previously been awarded the IDIQ to engage in an additional competitive bidding process before a task order is issued. The increased competition, in turn, may require us to make sustained efforts to reduce costs in order to realize revenue and profits under government contracts. If we are not successful in reducing the amount of costs we incur, our profitability on government contracts will be negatively impacted. The U.S. federal government has also increased its use of IDIQs in which the client qualifies multiple contractors for a specific program and then awards specific task orders or projects among the qualified contractors. As a result, new work awards tend to be smaller and of shorter duration, since the orders represent individual tasks rather than large, programmatic assignments. In addition, the U.S. government has announced its intention to scale back outsourcing of services in favor of "insourcing" jobs to its employees, which could reduce our revenue. Moreover, even if we are qualified to work on a government contract, we may not be awarded the contract because of existing government policies designed to protect small businesses and underrepresented minority contractors. Our inability to win or renew government contracts during regulated procurement processes could harm our operations and significantly reduce or eliminate our profits.

Each year, client funding for some of our government contracts may rely on government appropriations or public-supported financing. If adequate public funding is delayed or is not available, then our profits and revenue could decline.

        Each year, client funding for some of our government contracts may directly or indirectly rely on government appropriations or public-supported financing such as the ARRA. However, ARRA-funded contracts have not been awarded for environmental projects as quickly as we had expected, and it is possible that ARRA funding will never be allocated to projects that represent opportunities for us to the extent that we anticipate, if at all. Legislatures may appropriate funds for a given project on a year-by-year basis, even though the project may take more than one year to perform. In addition, public-supported financing such as state and local municipal bonds may be only partially raised to support existing projects. Public funds and the timing of payment of these funds may be influenced by, among other things, the state of the economy, competing political priorities, curtailments in the use of government contracting firms, increases in raw material costs, delays associated with insufficient numbers of government staff to oversee contracts, budget constraints, the timing and amount of tax receipts and the overall level of government expenditures. If adequate public funding is not available or is delayed, then our profits and revenue could decline.

Our government contracts may give government agencies the right to modify, delay, curtail, renegotiate or terminate existing contracts at their convenience at any time prior to their completion, and if we do not replace these contracts, we may suffer a decline in our profits and revenue.

        Government projects in which we participate as a contractor or subcontractor may extend for several years. Generally, government contracts include the right to modify, delay, curtail, renegotiate or terminate contracts and subcontracts at the government's convenience any time prior to their completion. Any decision by a government client to modify, delay, curtail, renegotiate or terminate our contracts at their convenience may result in a decline in our profits and revenue.

If we fail to complete a project in a timely manner, miss a required performance standard or otherwise fail to adequately perform on a project, then we may incur a loss on that project, which may reduce or eliminate our overall profitability.

        Our engagements often involve large-scale, complex projects. The quality of our performance on such projects depends in large part upon our ability to manage the relationship with our clients and our ability to effectively manage the project and deploy appropriate resources, including third-party contractors and our own personnel, in a timely manner. We may commit to a client that we will complete a project by a scheduled date. We may also commit that a project, when completed, will achieve specified performance standards. If the project is not completed by the scheduled date or fails to meet required performance standards, we may either incur significant additional costs or be held responsible for the costs incurred by the client to rectify damages due to late completion or failure to achieve the required performance standards. The uncertainty of the timing of a project can present difficulties in planning the amount of personnel needed for the project. If the project is delayed or canceled, we may bear the cost of an underutilized workforce that was dedicated to fulfilling the project. In addition, performance of projects can be affected by a number of factors beyond our control, including unavoidable delays from government inaction, public opposition, inability to obtain financing, weather conditions, unavailability of vendor materials, changes in the project scope of services requested by our clients, industrial accidents, environmental hazards, labor disruptions and other factors. To the extent these events occur, the total costs of the project could exceed our estimates and we could experience reduced profits or, in some cases, incur a loss on a project, which may reduce or eliminate our overall profitability. Further, any defects or errors, or failures to meet our clients' expectations, could result in claims for damages against us. Our contracts generally limit our liability for damages that arise from negligent acts, errors, mistakes or omissions in rendering services to our clients. However, we cannot be sure that these contractual provisions will protect us from liability for damages in the event we are sued.

The loss of key personnel or our inability to attract and retain qualified personnel could significantly disrupt our business.

        As primarily a professional and technical services company, we are labor-intensive and, therefore, our ability to attract, retain and expand our senior management and our professional and technical staff is an important factor in determining our future success. With limited exceptions, we do not have employment agreements with any of these individuals. The loss of the services of any of these key personnel could adversely affect our business. Although we have obtained non-compete agreements from certain principals and stockholders of companies we have acquired, we generally do not have non-compete or employment agreements with key employees who were once equity holders of these companies. Further, many of our non-compete agreements have expired. We do not maintain key-man life insurance policies on any of our executive officers or senior managers.

        The market for qualified scientists and engineers is competitive and we may not be able to attract and retain such professionals. In addition, it may be difficult to attract and retain qualified individuals in the timeframe demanded by our clients. For example, some of our government contracts may require us to employ only individuals who have particular government security clearance levels. In an effort to attract key employees, we often grant them stock options, and a reduction in our stock price could impact our ability to retain these professionals. Our failure to attract and retain key individuals could impair our ability to provide services to our clients and conduct our business effectively.

Our actual business and financial results could differ from the estimates and assumptions that we use to prepare our financial statements, which may significantly reduce or eliminate our profits.

        To prepare financial statements in conformity with generally accepted accounting principles ("GAAP") in the United States, management is required to make estimates and assumptions as of the

33


Table of Contents


date of the financial statements. These estimates and assumptions affect the reported values of assets, liabilities, revenue and expenses, as well as disclosures of contingent assets and liabilities. For example, we recognize revenue over the life of a contract based on the proportion of costs incurred to date compared to the total costs estimated to be incurred for the entire project. Areas requiring significant estimates by our management include:

    The application of the percentage-of-completion method of accounting and revenue recognition on contracts, change orders and contract claims;

    Provisions for uncollectible receivables and client claims and recoveries of costs from subcontractors, vendors and others;

    Provisions for income taxes, research and experimentation credits ("R&E credits") and related valuation allowances;

    Value of goodwill and recoverability of other intangible assets;

    Valuations of assets acquired and liabilities assumed in connection with business combinations;

    Estimated earn-out payments due in connection with business combinations;

    Valuation of employee benefit plans;

    Valuation of stock-based compensation expense; and

    Accruals for estimated liabilities, including litigation and insurance reserves.

        Our actual business and financial results could differ from those estimates, which may significantly reduce or eliminate our profits.

Our profitability could suffer if we are not able to maintain adequate utilization of our workforce.

        The cost of providing our services, including the extent to which we utilize our workforce, affects our profitability. The rate at which we utilize our workforce is affected by a number of factors, including:

    Our ability to transition employees from completed projects to new assignments and to hire and assimilate new employees;

    Our ability to forecast demand for our services and thereby maintain an appropriate headcount in each of our geographies and workforces;

    Our ability to manage attrition;

    Our need to devote time and resources to training, business development, professional development and other non-chargeable activities; and

    Our ability to match the skill sets of our employees to the needs of the marketplace.

        If we over-utilize our workforce, our employees may become disengaged, which will impact employee attrition. If we under-utilize our workforce, our profit margin and profitability could suffer.

Our use of the percentage-of-completion method of revenue recognition could result in a reduction or reversal of previously recorded revenue and profits.

        We account for most of our contracts on the percentage-of-completion method of revenue recognition. Generally, our use of this method results in recognition of revenue and profit ratably over the life of the contract, based on the proportion of costs incurred to date to total costs expected to be incurred for the entire project. The effects of revisions to revenue and estimated costs, including the achievement of award fees as well as the impact of change orders and claims, are recorded when the

34


Table of Contents


amounts are known and can be reasonably estimated. Such revisions could occur in any period and their effects could be material. Although we have historically made reasonably reliable estimates of the progress towards completion of long-term contracts, the uncertainties inherent in the estimating process make it possible for actual costs to vary materially from estimates, including reductions or reversals of previously recorded revenue and profit.

Our business and operating results could be adversely affected by our inability to accurately estimate the overall risks, revenue or costs on a contract.

        It is important for us to accurately estimate and control our contract costs so that we can maintain positive operating margins and profitability. We generally enter into three principal types of contracts with our clients: fixed-price, time-and-materials and cost-plus.

        Under our fixed-price contracts, we receive a fixed price irrespective of the actual costs we incur and, consequently, we are exposed to a number of risks. These risks include underestimation of costs, problems with new technologies, unforeseen costs or difficulties, delays beyond our control, price increases for materials, and economic and other changes that may occur during the contract period. Consequently, we realize a profit on fixed-price contracts only if we can control our costs and prevent cost over-runs on our contracts. Under our time-and-materials contracts, we are paid for labor at negotiated hourly billing rates and also paid for other expenses. Profitability on these contracts is driven by billable headcount and cost control. Many of our time-and-materials contracts are subject to maximum contract values and, accordingly, revenue relating to these contracts is recognized as if these contracts were fixed-price contracts. Under our cost-plus contracts, some of which are subject to contract ceiling amounts, we are reimbursed for allowable costs and fees, which may be fixed or performance-based. If our costs exceed the contract ceiling or are not allowable under the provisions of the contract or any applicable regulations, we may not be able to obtain reimbursement for all of the costs we incur.

        Profitability on our contracts is driven by billable headcount and our ability to manage our subcontractors, vendors and material suppliers. If we are unable to accurately estimate and manage our costs, we may incur losses on our contracts, which could decrease our operating margins and significantly reduce or eliminate our profits. Certain of our contracts require us to satisfy specific design, engineering, procurement or construction milestones in order to receive payment for the work completed or equipment or supplies procured prior to achievement of the applicable milestone. As a result, under these types of arrangements, we may incur significant costs or perform significant amounts of services prior to receipt of payment. If a customer determines not to proceed with the completion of the project or if the customer defaults on its payment obligations, we may face difficulties in collecting payment of amounts due to us for the costs previously incurred or for the amounts previously expended to purchase equipment or supplies.

        Accounting for a contract requires judgments relative to assessing the contract's estimated risks, revenue, costs and other technical issues. Due to the size and nature of many of our contracts, the estimation of overall risk, revenue and cost at completion is complicated and subject to many variables. Changes in underlying assumptions, circumstances or estimates may also adversely affect future period financial performance. If we are unable to accurately estimate the overall revenue or costs on a contract, then we may experience a lower profit or incur a loss on the contract.

Our failure to win new contracts and renew existing contracts with private and public sector clients could adversely affect our profitability.

        Our business depends on our ability to win new contracts and renew existing contracts with private and public sector clients. Contract proposals and negotiations are complex and frequently involve a lengthy bidding and selection process, which is affected by a number of factors. These factors include

35


Table of Contents


market conditions, financing arrangements and required governmental approvals. For example, a client may require us to provide a bond or letter of credit to protect the client should we fail to perform under the terms of the contract. If negative market conditions arise, or if we fail to secure adequate financial arrangements or the required government approval, we may not be able to pursue particular projects, which could adversely affect our profitability.

We have made and expect to continue to make acquisitions that could disrupt our operations and adversely impact our business and operating results. Our ability to successfully integrate acquisitions could impede us from realizing all of the benefits of the acquisitions, which could weaken our results of operations.

        A key part of our growth strategy is to acquire other companies that complement our lines of business or that broaden our technical capabilities and geographic presence. We expect to continue to acquire companies as an element of our growth strategy; however, our ability to make acquisitions is restricted under our credit agreement. Acquisitions involve certain known and unknown risks that could cause our actual growth or operating results to differ from our expectations or the expectations of securities analysts. For example:

    We may not be able to identify suitable acquisition candidates or to acquire additional companies on acceptable terms;

    We are pursuing international acquisitions, which inherently pose more risk than domestic acquisitions;

    We compete with others to acquire companies, which may result in decreased availability of, or increased price for, suitable acquisition candidates;

    We may not be able to obtain the necessary financing, on favorable terms or at all, to finance any of our potential acquisitions;

    We may ultimately fail to consummate an acquisition even if we announce that we plan to acquire a company; and

    Acquired companies may not perform as we expect, and we may fail to realize anticipated revenue and profits.

        In addition, our acquisition strategy may divert management's attention away from our existing businesses, resulting in the loss of key clients or key employees, and expose us to unanticipated problems or legal liabilities, including responsibility as a successor-in-interest for undisclosed or contingent liabilities of acquired businesses or assets.

        Our inability to successfully integrate future acquisitions could impede us from realizing all of the benefits of those acquisitions and could severely weaken our business operations. The integration process may disrupt our business and, if implemented ineffectively, may preclude realization of the full benefits expected by us and could harm our results of operations. In addition, the overall integration of the combining companies may result in unanticipated problems, expenses, liabilities, and competitive responses, and may cause our stock price to decline. The difficulties of integrating an acquisition include, among others:

    Unanticipated issues in integration information, communications and other systems;

    Unanticipated incompatibility of logistics, marketing and administration methods;

    Maintaining employee morale and retaining key employees;

    Integrating the business cultures of both companies;

    Preserving important strategic customer relationships;

36


Table of Contents

    Consolidating corporate and administrative infrastructures and eliminating duplicative operations; and

    Coordinating geographically separate organizations.

        In addition, even if the operations of an acquisition are integrated successfully, we may not realize the full benefits of the acquisition, including the synergies, cost savings or growth opportunities that we expect. These benefits may not be achieved within the anticipated time frame, or at all.

        Further, acquisitions may also cause us to:

    Issue common stock that would dilute our current stockholders' ownership percentage;

    Use a substantial portion of our cash resources;

    Increase our interest expense, leverage and debt service requirements if we incur additional debt to pay for an acquisition;

    Assume liabilities, including environmental liabilities, for which we do not have indemnification from the former owners. Further, indemnification obligations may be subject to dispute or concerns regarding the creditworthiness of the former owners;

    Record goodwill and non-amortizable intangible assets that are subject to impairment testing on a regular basis and potential impairment charges;

    Experience volatility in earnings due to changes in contingent consideration related to acquisition earn-out liability estimates;

    Incur amortization expenses related to certain intangible assets;

    Lose existing or potential contracts as a result of conflict of interest issues;

    Incur large and immediate write-offs; or

    Become subject to litigation.

        Finally, acquired companies that derive a significant portion of their revenue from the U.S. federal government and that do not follow the same cost accounting policies and billing practices that we follow may be subject to larger cost disallowances for greater periods than we typically encounter. If we fail to determine the existence of unallowable costs and do not establish appropriate reserves in advance of an acquisition, we may be exposed to material unanticipated liabilities, which could have a material adverse effect on our business.

If our goodwill or other intangible assets become impaired, then our profits may be significantly reduced.

        Because we have historically acquired a significant number of companies, goodwill and other intangible assets have represented a substantial portion of our assets. As of October 3, 2010, our goodwill was $394.4 million and other intangible assets were $46.0 million. We are required to perform a goodwill and indefinite-lived intangible asset impairment test for potential impairment at least on an annual basis. The goodwill impairment test requires us to determine the fair value of our reporting units, which are the components one level below our four reportable segments. In determining fair value, we make significant judgments and estimates, including assumptions about our strategic plans with regard to our operations. We also analyze current economic indicators and market valuations to help determine fair value. To the extent economic conditions that would impact the future operations of our reporting units change, our goodwill may be deemed to be impaired, and we would be required to record a non-cash charge that could result in a material adverse effect on our financial position or results of operations.

If we are not able to successfully manage our growth strategy, our business and results of operations may be adversely affected.

        Our expected future growth presents numerous managerial, administrative, operational and other challenges. Our ability to manage the growth of our operations will require us to continue to improve our management information systems and our other internal systems and controls. In addition, our growth will increase our need to attract, develop, motivate and retain both our management and professional employees. The inability of our management to effectively manage our growth or the inability of our employees to achieve anticipated performance could have a material adverse effect on our business.

Our backlog is subject to cancellation and unexpected adjustments, and is an uncertain indicator of future operating results.

        Our backlog as of October 3, 2010 was $1.9 billion. We include in backlog only those contracts for which funding has been provided and work authorizations have been received. We cannot guarantee that the revenue projected in our backlog will be realized or, if realized, will result in profits. In addition, project cancellations or scope adjustments may occur, from time to time, with respect to contracts reflected in our backlog. For example, certain of our contracts with the U.S. federal government and other clients are terminable at the discretion of the client, with or without cause. These types of backlog reductions could adversely affect our revenue and margins. Accordingly, our backlog as of any particular date is an uncertain indicator of our future earnings.

Our international operations are subject to a number of risks that could significantly reduce our revenue and profits, or subject us to criminal and civil enforcement actions.

        During fiscal 2010, we generated 9.5% of our revenue from our foreign operations, primarily in Canada, and from international clients for work that is performed by our domestic operations. International business is subject to a variety of risks, including:

    Lack of developed legal systems to enforce contractual rights;

    Greater risk of uncollectible accounts and longer collection cycles;

    Currency fluctuations;

    The potential for greater physical security risks, which may cause us to leave a country quickly;

    Logistical and communication challenges;

    Potentially adverse changes in laws and regulatory practices;

    Changes in labor conditions;

    General economic, political and financial conditions in foreign markets; and

    Exposure to civil or criminal liability under the Foreign Corrupt Practices Act ("FCPA") and other international regulations. For example, practices in the local business community outside the United States might not conform to international business standards and could violate anticorruption regulations, including the FCPA, which prohibits giving or offering to give anything of value with the intent to influence the awarding of government contracts.

        International risks and violations of international regulations may significantly reduce our profits and revenue and subject us to criminal or civil enforcement actions, including fines, suspensions or disqualification from future U.S. federal procurement contracting. Although we have policies and procedures to ensure legal and regulatory compliance, our employees, subcontractors and agents could

38


Table of Contents


take actions that violate these requirements. As a result, our international risk exposure may be more or less than the percentage of revenue attributed to our international operations.

If our business partners fail to perform their contractual obligations on a project, we could be exposed to legal liability, loss of reputation and profit reduction or loss on the project.

        We routinely enter into subcontracts and, occasionally, teaming arrangements and other contractual arrangements so that we can jointly bid and perform on a particular project. Success under these arrangements depends in large part on whether our business partners fulfill their contractual obligations satisfactorily. If any of our business partners fail to satisfactorily perform their contractual obligations as a result of financial or other difficulties, we may be required to incur additional costs and provide additional services in order to make up for our business partners' shortfall. If we are unable to adequately address our business partners' performance issues, then our client could terminate the joint project, exposing us to legal liability, loss of reputation and reduced profit or loss on the project.

If our contractors and subcontractors fail to satisfy their obligations to us or other parties, or if we are unable to maintain these relationships, our revenue, profitability and growth prospects could be adversely affected.

        We depend on contractors and subcontractors in conducting our business. There is a risk that we may have disputes with our subcontractors arising from, among other things, the quality and timeliness of work performed by the subcontractor, client concerns about the subcontractor, or our failure to extend existing task orders or issue new task orders under a subcontract. In addition, if any of our subcontractors fail to deliver on a timely basis the agreed-upon supplies, fail to perform the agreed-upon services or go out of business, then our ability to fulfill our obligations as a prime contractor may be jeopardized.

        We also rely on relationships with other contractors when we act as their subcontractor or joint venture partner. The absence of qualified subcontractors with which we have a satisfactory relationship could adversely affect the quality of our service and our ability to perform under some of our contracts. Our future revenue and growth prospects could be adversely affected if other contractors eliminate or reduce their subcontracts or teaming arrangement relationships with us, or if a government agency terminates or reduces these other contractors' programs, does not award them new contracts or refuses to pay under a contract.

Changes in resource management or infrastructure industry laws, regulations and programs could directly or indirectly reduce the demand for our services, which could in turn negatively impact our revenue.

        Some of our services are directly or indirectly impacted by changes in U.S. federal, state, local or foreign laws and regulations pertaining to resource management, infrastructure and the environment. Accordingly, a relaxation or repeal of these laws and regulations, or changes in governmental policies regarding the funding, implementation or enforcement of these programs, could result in a decline in demand for our services, which could in turn negatively impact our revenue.

Changes in capital markets could adversely affect our access to capital and negatively impact our business.

        Our results could be adversely affected by an inability to access our $300 million revolving credit facility. Unfavorable financial or economic conditions could impact certain issuers' willingness or ability to fund our revolving credit facility. In addition, increases in interest rates or credit spreads, volatility in financial markets or the interest rate environment, significant political or economic events, defaults of significant issuers and other market and economic factors may negatively impact the general level of

39


Table of Contents


debt issuance, the debt issuance plans of certain categories of borrowers, the types of credit-sensitive products being offered, and/or a sustained period of market decline or weakness could have a material adverse effect on us.

Restrictive covenants in our credit agreement may restrict our ability to pursue certain business strategies.

        Our credit agreement restricts our ability to, among other things:

    Incur additional indebtedness;

    Create liens securing debt or other encumbrances on our assets;

    Make loans or advances;

    Pay dividends or make distributions to our stockholders;

    Purchase or redeem our stock;

    Repay indebtedness that is junior to indebtedness under our credit agreement;

    Acquire the assets of, or merge or consolidate with, other companies; and

    Sell, lease or otherwise dispose of assets.

        Our credit agreement also requires that we maintain certain financial ratios, which we may not be able to achieve. The covenants may impair our ability to finance future operations or capital needs or to engage in other favorable business activities.

Our industry is highly competitive and we may be unable to compete effectively.

        Our industry is highly fragmented and intensely competitive. Our competitors are numerous, ranging from small private firms to multi-billion dollar public companies. In addition, the technical and professional aspects of our services generally do not require large upfront capital expenditures and provide limited barriers against new competitors. Some of our competitors have achieved greater market penetration in some of the markets in which we compete, and some have substantially more financial resources and/or financial flexibility than we do. As a result of the number of competitors in the industry, our clients may select one of our competitors on a project due to competitive pricing or a specific skill set. These competitive forces could force us to make price concessions or otherwise reduce prices for our services. If we are unable to maintain our competitiveness, our market share, revenue and profits will decline.

The value of our common stock could be volatile.

        Our common stock has previously experienced substantial price volatility. In addition, the stock market has experienced extreme price and volume fluctuations that have affected the market price of many companies and that have often been unrelated to the operating performance of these companies. The overall market and the price of our common stock may fluctuate greatly. The trading price of our common stock may be significantly affected by various factors, including:

    Quarter-to-quarter variations in our financial results, including revenue, profits, days sales outstanding, backlog, and other measures of financial performance or financial condition;

    Our announcements or our competitors' announcements of significant events, including acquisitions;

    Resolution of threatened or pending litigation;

40


Table of Contents

    Changes in investors' and analysts' perceptions of our business or any of our competitors' businesses;

    Investors' and analysts' assessments of reports prepared or conclusions reached by third parties;

    Changes in environmental legislation;

    Investors' perceptions of our performance of services in countries in which the U.S. military is engaged, including Iraq and Afghanistan;

    Broader market fluctuations; and

    General economic or political conditions.

        Additionally, volatility or a lack of positive performance in our stock price may adversely affect our ability to retain key employees, many of whom are granted stock options and shares of restricted stock, the value of which is dependent on the performance of our stock price.

Legal proceedings, investigations and disputes could result in substantial monetary penalties and damages, especially if such penalties and damages exceed or are excluded from existing insurance coverage.

        We engage in consulting, engineering, program management, construction and technical services that can result in substantial injury or damages that may expose us to legal proceedings, investigations and disputes. For example, in the ordinary course of our business, we may be involved in legal disputes regarding personal injury claims, employee or labor disputes, professional liability claims, and general commercial disputes involving project cost overruns and liquidated damages as well as other claims. In addition, in the ordinary course of our business, we frequently make professional judgments and recommendations about environmental and engineering conditions of project sites for our clients. We may be deemed to be responsible for these judgments and recommendations if they are later determined to be inaccurate. Any unfavorable legal ruling against us could result in substantial monetary damages or even criminal violations. We maintain insurance coverage as part of our overall legal and risk management strategy to minimize our potential liabilities; however, insurance coverage contains exclusions and other limitations that may not cover our potential liabilities. Generally, our insurance program covers workers' compensation and employer's liability, general liability, automobile liability, professional errors and omissions liability, property, and contractor's pollution liability (in addition to other policies for specific projects). Our insurance program includes deductibles or self-insured retentions for each covered claim. In addition, our insurance policies contain exclusions that insurance providers may use to deny or restrict coverage. Excess liability and professional liability insurance policies provide for coverages on a "claims-made" basis, covering only claims actually made and reported during the policy period currently in effect. If we sustain liabilities that exceed or that are excluded from our insurance coverage or for which we are not insured, it could have a material adverse impact on our results of operations and financial condition, including our profits and revenue.

Unavailability or cancellation of third-party insurance coverage would increase our overall risk exposure as well as disrupt the management of our business operations.

        We maintain insurance coverage from third-party insurers as part of our overall risk management strategy and because some of our contracts require us to maintain specific insurance coverage limits. If any of our third-party insurers fail, suddenly cancel our coverage or otherwise are unable to provide us with adequate insurance coverage then our overall risk exposure and our operational expenses would increase and the management of our business operations would be disrupted. In addition, there can be no assurance that any of our existing insurance coverage will be renewable upon the expiration of the coverage period or that future coverage will be affordable at the required limits.

Our inability to obtain adequate bonding could have a material adverse effect on our future revenue and business prospects.

        Certain clients require bid bonds and performance and payment bonds. These bonds indemnify the client should we fail to perform our obligations under a contract. If a bond is required for a particular project and we are unable to obtain an appropriate bond, we cannot pursue that project. In some instances, we are required to co-venture with a small or disadvantaged business to pursue certain U.S. federal or state government contracts. In connection with these ventures, we are sometimes required to utilize our bonding capacity to cover all of the payment and performance obligations under the contract with the client. We have a bonding facility but, as is typically the case, the issuance of bonds under that facility is at the surety's sole discretion. Moreover, due to events that can negatively affect the insurance and bonding markets, bonding may be more difficult to obtain or may only be available at significant additional cost. There can be no assurance that bonds will continue to be available to us on reasonable terms. Our inability to obtain adequate bonding and, as a result, to bid on new work could have a material adverse effect on our future revenue and business prospects.

Employee, agent or partner misconduct or our overall failure to comply with laws or regulations could harm our reputation, reduce our revenue and profits, and subject us to criminal and civil enforcement actions.

        Misconduct, fraud, non-compliance with applicable laws and regulations, or other improper activities by one of our employees, agents or partners could have a significant negative impact on our business and reputation. Such misconduct could include the failure to comply with government procurement regulations, regulations regarding the protection of classified information, regulations prohibiting bribery and other foreign corrupt practices, regulations regarding the pricing of labor and other costs in government contracts, regulations on lobbying or similar activities, regulations pertaining to the internal controls over financial reporting, environmental laws and any other applicable laws or regulations. For example, the FCPA and similar anti-bribery laws in other jurisdictions generally prohibit companies and their intermediaries from making improper payments to non-U.S. officials for the purpose of obtaining or retaining business. Our policies mandate compliance with these regulations and laws, and we take precautions to prevent and detect misconduct. However, since our internal controls are subject to inherent limitations, including human error, it is possible that these controls could be intentionally circumvented or become inadequate because of changed conditions. As a result, we cannot assure that our controls will protect us from reckless or criminal acts committed by our employees and agents. Our failure to comply with applicable laws or regulations or acts of misconduct could subject us to fines and penalties, loss of security clearances, and suspension or debarment from contracting, any or all of which could harm our reputation, reduce our revenue and profits, and subject us to criminal and civil enforcement actions.

Our business activities may require our employees to travel to and work in countries where there are high security risks, which may result in employee death or injury, repatriation costs or other unforeseen costs.

        Certain of our contracts may require our employees travel to and work in high-risk countries that are undergoing political, social and economic upheavals resulting in war, civil unrest, criminal activity, acts of terrorism or public health crises. For example, we currently have employees working in Afghanistan and Pakistan. As a result, we risk loss of or injury to our employees and may be subject to costs related to employee death or injury, repatriation or other unforeseen circumstances. We may choose or be forced to leave a country with little or no warning due to physical security risks.

Our failure to implement and comply with our safety program could adversely affect our operating results or financial condition.

        Our safety program is a fundamental element of our overall approach to risk management, and the implementation of the safety program is a significant issue in our dealings with our clients. We maintain an enterprise-wide group of health and safety professionals to help ensure that the services we provide are delivered safely and in accordance with standard work processes. Unsafe job sites and office environments have the potential to increase employee turnover, increase the cost of a project to our clients, expose us to types and levels of risk that are fundamentally unacceptable, and raise our operating costs. The implementation of our safety processes and procedures are monitored by various agencies and rating bureaus, and may be evaluated by certain clients in cases in which safety requirements have been established in our contracts. If we fail to meet these requirements or do not properly implement and comply with our safety program, there could be a material adverse effect on our business, operating results or financial condition.

We may be precluded from providing certain services due to conflict of interest issues.

        Many of our clients are concerned about potential or actual conflicts of interest in retaining management consultants. U.S. federal government agencies have formal policies against continuing or awarding contracts that would create actual or potential conflicts of interest with other activities of a contractor. These policies, among other things, may prevent us from bidding for or performing government contracts resulting from or relating to certain work we have performed. In addition, services performed for a commercial or government client may create a conflict of interest that precludes or limits our ability to obtain work from other public or private organizations. We have, on occasion, declined to bid on projects due to conflict of interest issues.

We may be subject to liabilities under environmental laws and regulations.

        We must comply with a number of governmental laws that strictly regulate the handling, removal, treatment, transportation and disposal of toxic and hazardous substances. Under the Comprehensive Environmental Response Compensation and Liability Act of 1980, as amended ("CERCLA"), and comparable state laws, we may be required to investigate and remediate regulated hazardous materials. CERCLA and comparable state laws typically impose strict, joint and several liabilities without regard to whether a company knew of or caused the release of hazardous substances. The liability for the entire cost of clean-up could be imposed upon any responsible party. Other principal federal environmental, health and safety laws affecting us include, but are not limited to, the Resource Conversation and Recovery Act, the NEPA, the Clean Air Act, the Occupational Safety and Health Act, the Toxic Substances Control Act and the Superfund Amendments and Reauthorization Act. Our business operations may also be subject to similar state and international laws relating to environmental protection. Liabilities related to environmental contamination or human exposure to hazardous substances, or a failure to comply with applicable regulations, could result in substantial costs to us, including clean-up costs, fines and civil or criminal sanctions, third-party claims for property damage or personal injury or cessation of remediation activities. Our continuing work in the areas governed by these laws and regulations exposes us to the risk of substantial liability.

Force majeure events, including natural disasters and terrorist actions could negatively impact the economies in which we operate or disrupt our operations, which may affect our financial condition, results of operations or cash flows.

        Force majeure or extraordinary events beyond the control of the contracting parties, such as natural and man-made disasters, as well as terrorist actions, could negatively impact the economies in which we operate by causing the closure of offices, interrupting projects and forcing the relocation of employees. Further, despite our implementation of network security measures, our servers are

43


Table of Contents


vulnerable to computer viruses, break-ins and similar disruptions from unauthorized tampering with our computer systems. We typically remain obligated to perform our services after a terrorist action or natural disaster unless the contract contains a force majeure clause that relieves us of our contractual obligations in such an extraordinary event. If we are not able to react quickly to force majeure, our operations may be affected significantly, which would have a negative impact on our financial condition, results of operations or cash flows.

We have only a limited ability to protect our intellectual property rights, and our failure to protect our intellectual property rights could adversely affect our competitive position.

        Our success depends, in part, upon our ability to protect our proprietary information and other intellectual property. We rely principally on trade secrets to protect much of our intellectual property where we do not believe that patent or copyright protection is appropriate or obtainable. However, trade secrets are difficult to protect. Although our employees are subject to confidentiality obligations, this protection may be inadequate to deter or prevent misappropriation of our confidential information. In addition, we may be unable to detect unauthorized use of our intellectual property or otherwise take appropriate steps to enforce our rights. Failure to obtain or maintain trade secret protection would adversely affect our competitive business position. In addition, if we are unable to prevent third parties from infringing or misappropriating our trademarks or other proprietary information, our competitive position could be adversely affected.

We rely on third-party internal and outsourced software to run our critical accounting, project management and financial information systems. As a result, any sudden loss, disruption or unexpected costs to maintain these systems could significantly increase our operational expense and disrupt the management of our business operations.

        We rely on third-party software to run our critical accounting, project management and financial information systems. We also depend on our software vendors to provide long-term software maintenance support for our information systems. Software vendors may decide to discontinue further development, integration or long-term software maintenance support for our information systems, in which case we may need to abandon one or more of our current information systems and migrate some or all of our accounting, project management and financial information to other systems, thus increasing our operational expense as well as disrupting the management of our business operations.

Item 1B.    Unresolved Staff Comments

        None.

Item 2.    Properties

        Our corporate headquarters is located in Pasadena, California. This leased facility contains approximately 68,000 square feet of office space. Substantially all of our properties, including those of our recent acquisitions, are leased in approximately 320 office locations in the United States and abroad. We own facilities located in Gloversville, New York; Casper, Wyoming; Virginia Beach, Virginia; and Shreveport, Louisiana that are used for operations. In total, our facilities contain approximately 2.2 million square feet of domestic office space and approximately 800,000 square feet of office space outside the United States. Our significant lease agreements expire at various dates through 2021. We also lease a number of warehouse and laboratory spaces, and rent additional office space on a month-to-month basis.

        We believe that our current facilities are adequate for the operation of our business and that suitable additional space in various local markets is available to accommodate any needs that may arise. None of our facilities are individually material to our operations.

Item 3.    Legal Proceedings

        We are subject to certain claims and lawsuits typically filed against the engineering, consulting and construction profession, alleging primarily professional errors or omissions. We carry professional liability insurance, subject to certain deductibles and policy limits, against such claims. However, in some actions, parties are seeking damages that exceed our insurance coverage or for which we are not insured. While management does not believe that the resolution of these claims will have a material adverse effect on our financial position, results of operations or cash flows, management acknowledges the uncertainty surrounding the ultimate resolution of these matters.

        In May 2003, Innovative Technologies Corporation ("ITC") filed a lawsuit in Montgomery County, Ohio against Advanced Management Technology, Inc. ("AMT") and other defendants for misappropriation of trade secrets, among other claims. In June 2004, we purchased all the outstanding shares of AMT. As part of the purchase agreement, the former owners of AMT agreed to indemnify us for all costs and damages related to this lawsuit. In December 2007, the case went to trial and the jury assessed $5.8 million in compensatory damages against AMT. In addition, the jury assessed $17 million in punitive damages against AMT plus reasonable attorneys' fees. In July 2008, the Common Pleas Court of Montgomery County denied AMT's motion for judgment notwithstanding the verdict and conditionally denied AMT's motion for a new trial. Further, the court remitted the verdict to $2.0 million in compensatory damages and $5.8 million in punitive damages. ITC accepted the remittitur, and AMT appealed. The appellate court remanded the matter to the trial court for ruling on ITC's motion for prejudgment interest and attorneys' fees. In December 2009, the trial court assessed ITC $2.9 million in attorneys' fees and costs, and denied ITC's motion for prejudgment interest. AMT appealed the trial court's decision assessing compensatory and punitive damages, and attorneys' fees and costs. ITC cross-appealed the trial court's decision to remit the jury verdict and the trial court's denial of prejudgment interest. Final briefs have been filed with the court of appeals and oral arguments have been scheduled in December 2010. AMT has posted a bond, as required by the trial court, for $13.4 million. We believe that a reasonably possible range of exposure, including attorneys' fees, is from $0 to approximately $14.5 million. As of October 3, 2010, we have recorded a liability representing our best estimate of a probable loss. Further, for the same amount, we have recorded a receivable from the former owners of AMT as we believe it is probable they will fully honor their indemnification agreement with us for any and all costs and damages related to this lawsuit.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS

GENERAL OVERVIEW

        We are a leading provider of consulting, engineering, program management, construction management and technical services focusing on resource management, infrastructure and the environment. We typically begin at the earliest stage of a project by applying science to problems and developing solutions tailored to our clients' needs and resources. Our solutions may span the entire life cycle of the project and include applied science, research and technology, engineering, design, construction management, construction, operations and maintenance, and information technology.

        We derive income from fees for professional, technical, project management and construction services. As primarily a service-based company, we are labor-intensive rather than capital-intensive. Our revenue is driven by our ability to attract and retain qualified and productive employees, identify business opportunities, secure new and renew existing client contracts, provide outstanding services to our clients and execute projects successfully. We provide our services to a diverse base of U.S. federal and state and local government agencies, as well as commercial and international clients. The following table presents the percentage of our revenue by client sector:

ACQUISITIONS AND DIVESTITURES

        Acquisitions.    We continuously evaluate the marketplace for strategic acquisition opportunities. Due to our reputation, size, financial resources, geographic presence and range of services, we have numerous opportunities to acquire privately and publicly held companies or selected portions of such companies. During our evaluation, we examine the effect an acquisition may have on our long-range business strategy and results of operations. Generally, we proceed with an acquisition if we believe that it would have a positive effect on future operations and could strategically expand our service offerings. As successful integration and implementation are essential to achieving favorable results, no assurance can be given that all acquisitions will provide accretive results. Our strategy is to position ourselves to address existing and emerging markets. We view acquisitions as a key component of our growth strategy, and we intend to use cash, debt or securities, as we deem appropriate, to fund acquisitions. We may acquire other businesses that we believe are synergistic and will ultimately increase our revenue and net income, strengthen our ability to achieve our strategic goals, provide critical mass with existing clients and further expand our lines of service. We typically pay a purchase price that results in the recognition of goodwill, generally representing the intangible value of a successful business with an assembled workforce specialized in our areas of interest.

        On October 1, 2007, we acquired ARD, which provides applied research, planning, design and implementation services focused on a range of water, energy, environmental and governance challenges.

ARD manages large, complex international development projects for its clients, predominantly USAID. This acquisition increased our professional workforce in new geographic areas and technical specialties around the world. ARD is part of our TSS segment. On January 28, 2009, we acquired Wardrop, a Canadian firm that specializes in resource management, energy and infrastructure design and is included in our ECS segment. This acquisition significantly expanded our worldwide presence with offices throughout Canada, and in the United Kingdom and India. On August 6, 2010, we acquired EBA, a Canadian firm that provides natural science, engineering and arctic engineering services to the mining, energy and infrastructure sectors. This acquisition strengthened our geographic presence, and added new customers and complementary technical services, in the ECS segment. On October 4, 2010, we acquired BPR, Inc. ("BPR"), a Canadian scientific and engineering services firm that provides multidisciplinary consulting and engineering support for water, energy, industrial plants, buildings and infrastructure projects. This acquisition further expands our geographic presence in eastern Canada, and enables us to provide our clients with services throughout Canada. BPR is part of our ECS segment. In fiscal 2008, 2009 and 2010, we made other acquisitions that enhanced our service offerings to broad-based clients and expanded our geographic presence across our segments.

        For analytical purposes only, we categorize our revenue into two types: acquisitive and organic. Acquisitive revenue consists of revenue derived from acquired companies during the first 12 months following their respective acquisition dates. Organic revenue consists of our total revenue less any acquisitive revenue.

        Divestitures.    To complement our acquisition strategy and our focus on internal growth, we regularly review and evaluate our existing operations to determine whether our business model should change through the divestiture of certain businesses. Accordingly, from time to time, we may divest certain non-core businesses and reallocate our resources to businesses that better align with our long-term strategic direction. In fiscal 2008, 2009 and 2010, we did not have any divestitures.

OVERVIEW OF RESULTS AND BUSINESS TRENDS

        Management review of fiscal 2010 and outlook for the future.    In fiscal 2010, our operating results improved compared to fiscal 2009 despite continuing difficult economic conditions. We continued our focus on organic growth and the strategic acquisition of firms that enhance our service offerings and expand our geographic presence. Although revenue declined, our revenue, net of subcontractor costs, increased 5.3% compared to fiscal 2009 due to contributions from recent acquisitions, strength in international mining projects, and certain state and local government projects. This growth was partially offset by continuing weakness in the federal construction management and commercial markets.

        We foresee a continued period of weakness in the economy, with a slow and gradual economic recovery. Despite this weakness, we expect that our revenue will grow moderately in fiscal 2011 compared to fiscal 2010 due to contributions from recent acquisitions and anticipated growth in our business. The U.S. federal government's stimulus plan contained in the ARRA may provide us with some additional business opportunities. However, since the passage of the ARRA, we have received significantly fewer and smaller-sized ARRA awards than anticipated. Because the timing and magnitude of any potential benefit to our business from the ARRA are uncertain, we cannot predict how meaningful such contributions may be in fiscal 2011. We also recognize that the economic conditions that have severely impacted both the domestic and international economies could adversely affect our future work for the U.S. federal government, state and local governments, and commercial and international clients.

        Federal Government.    Our U.S. federal government business declined 1.9% in fiscal 2010 compared to fiscal 2009. The decline resulted primarily from the prior-year completion of Iraq-related projects for the DoD, reduced activities on certain USAID projects in Colombia and a large remediation project. The decline was partially offset by increased activity on EPA, DOE and FAA

51

projects. Also, we experienced increased activity on USAID international development and DoD infrastructure design projects in Afghanistan. During periods of economic volatility, our U.S. federal government business has historically been the most stable and predictable. However, we continue to experience delays on new awards for certain large construction management-related projects in Afghanistan and the U.S. Gulf Coast region. Despite these delays on our back-end construction management projects, we are experiencing significant strength in our front-end water and environmental projects for U.S. federal government clients, such as the USACE and EPA. As a result, revenue from our U.S. federal government business is expected to be flat in fiscal 2011 compared to fiscal 2010.

        State and Local Government.    Our state and local government business grew 17.4% in fiscal 2010 compared to fiscal 2009. The growth was driven by a large transportation infrastructure project as well as from certain solid waste and water projects associated with prior-year acquisitions. Apart from these projects, we continue to experience difficult economic conditions across our state and local government markets. Many state and local government agencies continue to face economic challenges, including budget deficits and difficult cost-cutting decisions. Simultaneously, states are facing major long-term infrastructure needs, including the need for maintenance, repair and upgrading of existing critical infrastructure and the need to build new facilities. The funding risks associated with our state and local government programs are partially mitigated by the regulatory requirements driving some of these programs, such as regulatory-mandated consent decrees, as well as demographic shifts and increasing demand for water and wastewater services. As a result, some programs will generally progress despite budget pressures. We expect ongoing economic challenges across many states and remain uncertain regarding the timing and magnitude of ARRA funds that may eventually benefit our state and local government business. We expect that our state and local government revenue will be flat in fiscal 2011 compared to fiscal 2010.

        Commercial.    Our commercial business declined 29.3% in fiscal 2010 compared to fiscal 2009. This decline was primarily attributable to the prior-year completion of several large wind energy projects, as well as reduced activity in fiscal 2010 on certain environmental remediation and water projects. We experienced project delays, cancellations and reduced workload in our real estate development and industrial sectors resulting from the weak economic conditions. We expect these economic conditions to continue and, therefore, our commercial business to be flat in fiscal 2011 compared to fiscal 2010.

        International.    Our international business grew 100.5% in fiscal 2010 compared to fiscal 2009. This growth was primarily driven by contributions from our recent acquisitions and strength in international mining projects. To a lesser extent, this growth resulted from an increase in our engineering and design services overseas. We expect that our international business will grow significantly in fiscal 2011 compared to fiscal 2010 as a result of our recent acquisitions. However, global economic weakness could result in lower revenue than anticipated if planned mining or energy projects are delayed or cancelled due to a decline in commodity and energy prices.

RESULTS OF OPERATIONS

        In fiscal 2010, we began reporting "Revenue", "Subcontractor costs" and "Operating income", and discontinued reporting "Gross profit" and the percentage relationship of certain items to revenue, net of subcontractor costs. In October 2010, our former "Environmental Consulting Services" segment was renamed the "Engineering and Consulting Services" segment. Certain corporate costs are not allocated to our reportable segments.

We believe that the presentation of "Revenue, net of subcontractor costs", a non-GAAP financial measure, enhances investors' ability to analyze our business trends and performance because it substantially measures the work performed by our employees. In the course of providing services, we routinely subcontract various services and, under certain USAID programs, issue grants. Generally, these subcontractor costs and grants are passed through to our clients and, in accordance with U.S. GAAP and industry practice, are included in our revenue when it is our contractual responsibility to procure or manage these activities. The grants are included as part of our subcontractor costs. Because subcontractor services can vary significantly from project to project and period to period, changes in revenue may not necessarily be indicative of our business trends. Accordingly, we segregate subcontractor costs from revenue to promote a better understanding of our business by evaluating revenue exclusive of costs associated with external service providers.

        Revenue declined due to the prior-year completion of several large wind energy and Iraq-related contracts, and reduced activity on certain USAID, environmental remediation and water projects. Additionally, the decline was attributable to U.S. federal government delays in releasing new awards, and reduced workload from commercial clients due to continuing weakness in the economy. The overall decline was partially offset by increased funding on EPA, DOE, FAA and other federal programs. Also, we experienced growth in our international business and increased activity on a large transportation infrastructure project. Further, the decline was partially mitigated by approximately $130 million in revenue contribution from acquisitions in fiscal 2010 and approximately $45 million in additional revenue in the fourth quarter as a result of the 53-week year in fiscal 2010 compared to the 52-week year in fiscal 2009.

        The growth in revenue, net of subcontractor costs, was driven by approximately $84 million in contributions from acquisitions and approximately $30 million related to the additional week in fiscal 2010. Excluding the effect of acquisitions, revenue, net of subcontractor costs, slightly declined compared to fiscal 2009. The dollar and percentage changes were more favorable than those for revenue due primarily to a significant decrease in subcontracting activity. This resulted from the prior-year completion of several wind energy and Iraq-related projects, which were substantially subcontracted. However, our subcontracting activities remained relatively high due to USAID, BRAC and certain water programs. Additionally, our program management activities on U.S. federal government contracts typically result in higher levels of subcontracting that are partially driven by government-mandated small business set-aside requirements.

        Operating income grew as a result of the increase in revenue, net of subcontractor costs. The increase in operating income was partially offset by additional selling, general and administrative ("SG&A") costs related to recent acquisitions, including $2.9 million of increased amortization expense related to intangible assets and $1.7 million of third-party acquisition costs.

        Net interest expense decreased due to lower average borrowings. We had minimal interest expense on our credit facility as we had no borrowings outstanding for most of fiscal 2010.

        Income tax expense increased due primarily to a higher effective tax rate. Our effective tax rate for fiscal 2010 was 37.6% compared to 27.0% for fiscal 2009. The prior-year tax rate benefited from a $3.3 million adjustment primarily from a settlement with the Internal Revenue Service ("IRS") for fiscal years 1997 through 2001, and the recognition of $9.7 million for previously unclaimed R&E credits for periods prior to fiscal 2009.

        Despite an increase in pre-tax income, net income decreased as a result of a higher effective tax rate for fiscal 2010 compared to fiscal 2009, for the reasons described above.

        Our recent acquisitions contributed approximately $96 million and $74 million to the growth in revenue and revenue, net of subcontractor costs, respectively. Excluding the effect of acquisitions, both revenue and revenue, net of subcontractor costs, grew 5.5%, driven primarily by demand for international mining services, and increased workload on federal, state and local government programs. The growth was partially offset by reduced revenue from a large environmental remediation project for a commercial client resulting from funding and contract delays.

        Operating income increased due primarily to revenue growth. Additionally, the increase resulted from reductions in overhead costs, labor and other employee-related expenses in certain low-activity business areas. Further, contract costs related to inclement weather, regulatory delays and subcontractor issues were lower in fiscal 2010.

        Revenue growth was driven by a fiscal 2010 acquisition, which contributed $8.3 million in revenue. Excluding the effect of the acquisition, TSS experienced a slight revenue decline from reduced activity on certain USAID and DoD projects. The overall decrease was partially mitigated by revenue growth from the EPA and other U.S. federal government agencies. Excluding the effect of acquisitions, revenue, net of subcontractor costs, grew 3.4% despite the aforementioned revenue decline. The growth resulted primarily from an increase in self-performed work, particularly on USAID and DoD projects.

        The increase in operating income substantially corresponded to the growth in revenue, net of subcontractor costs. The increase also resulted from improved project performance on certain fixed-price contracts.

        Both revenue and revenue, net of subcontractor costs, declined in the commercial sector, particularly in the real estate development and industrial markets. Our state and local government sector declined due to budget and spending constraints. The decline was partially mitigated by aggregate revenue growth of approximately $25 million in international and U.S. federal government sectors. The percentage decrease in revenue, net of subcontractor costs, was higher than that for revenue due to the increased level of subcontracting activity on the international and U.S. federal government work.

        Operating income decreased due largely to the aforementioned revenue decline. Further, in the second quarter of fiscal 2010, we recognized $3.1 million in losses on accounts receivable on certain commercial development and infrastructure projects. The decrease in operating income was partially mitigated by improved performance on international projects and reductions in overhead costs, labor and other employee-related expenses that corresponded to the aforementioned revenue decline.

        Revenue declined as a result of the prior-year completion of several large contracts, primarily wind energy and Iraq-related projects, and reduced activity on a large water project for a commercial client. Revenue from remediation and construction work also decreased due to U.S. federal government delays in releasing new awards. Since wind energy and Iraq-related projects were substantially subcontracted, revenue, net of subcontractor costs, was not impacted by the completion of these projects to the same extent as revenue. The overall decline was partially offset by increased activity on DOE and other U.S. federal government programs, as well as a large transportation infrastructure project with a state government client. To a lesser extent, the decline was partially mitigated by the effect of a prior-year acquisition in the amounts of approximately $26 million and $6 million for revenue and revenue, net of subcontractor costs, respectively.

        Operating income decreased due largely to the aforementioned revenue decline. Further, the prior-year operating income benefited from favorable claim settlements and higher profit margins on certain commercial wind energy, water and telecommunication projects. The decrease in operating income was partially offset by current-year reductions in the provisions for accounts receivable, as well as lower overhead costs, labor and other employee-related expenses that corresponded to the revenue decline in remediation and construction work.

We believe that the presentation of "Revenue, net of subcontractor costs", a non-GAAP financial measure, enhances investors' ability to analyze our business trends and performance because it substantially measures the work performed by our employees. In the course of providing services, we routinely subcontract various services and, under certain USAID programs, issue grants. Generally, these subcontractor costs and grants are passed through to our clients and, in accordance with U.S. GAAP and industry practice, are included in our revenue when it is our contractual responsibility to procure or manage these activities. The grants are included as part of our subcontractor costs. Because subcontractor services can vary significantly from project to project and period to period, changes in revenue may not necessarily be indicative of our business trends. Accordingly, we segregate subcontractor costs from revenue to promote a better understanding of our business by evaluating revenue exclusive of costs associated with external service providers.

        Revenue and revenue, net of subcontractor costs, increased by approximately $153 million and $127 million, respectively, due to our acquisitions, particularly Wardrop, which enhanced our international business. In addition, our U.S. federal government business grew as a result of increased activity on BRAC, USAID, DOE, FAA, NASA, EPA and other domestic projects. We also experienced increased demand for our wind energy, water, and engineering and development services in our commercial business. However, the overall growth was partially offset by the wind-down of Iraq-related projects. To a lesser extent, we experienced revenue declines in our state and local government business, and in certain areas of our commercial business because of budget and spending constraints.

        Revenue, net of subcontractor costs, increased at a higher growth rate than our revenue due to contract mix, because subcontractor services can change significantly from project to project and from period to period. More specifically, we experienced a decline in subcontracting activity, as a percentage of revenue, due to the prior-year completion of Iraq-related contracts and certain large wind energy projects, which were largely subcontracted. Overall, our subcontracting activities remained high due to wind energy, BRAC and certain water programs. Further, our program management activities on U.S. federal government contracts typically result in higher levels of subcontracting that are partially driven by government-mandated small business set-aside requirements.

        The increase in operating income substantially corresponded to the growth in revenue, net of subcontractor costs. Additionally, the increase resulted from improved contract performance on a few large fixed-price contracts related to wind energy, water, and engineering and development projects as

well as lower litigation costs. The overall increase was partially offset by increased costs on certain new programs, regulatory and project delays, subcontractor issues and the provision for losses on certain accounts receivable from commercial clients. To a lesser extent, the increase was partially offset by additional amortization expense related to intangible assets associated with our recent acquisitions and expanded business development activities.

        Net interest expense decreased due to lower interest expense driven by lower interest rates and lower average borrowings. Similarly, we recognized lower interest income from short-term cash investments due to lower interest rates.

        Income tax expense decreased due to a tax settlement with the IRS and the recognition of previously unclaimed R&E credits based on completed studies and analyses. Our effective tax rates were 27.0% and 41.1% for fiscal 2009 and 2008, respectively.

        Net income grew 42.9% compared to fiscal 2008 due to higher pre-tax income as a result of business growth and a lower effective tax rate, for the reasons described above.

        Revenue and revenue, net of subcontractor costs, increased by approximately $109 million and $102 million, respectively, as a result of our acquisitions, particularly Wardrop, which enhanced our international business. This segment also experienced organic growth in its U.S. federal, and state and local government businesses. Further, increased workload on a large environmental remediation project for a commercial client contributed to the growth. However, this segment's commercial business declined on an overall basis due to reduced demand for geotechnical and mining services resulting from the economic downturn. Revenue, net of subcontractor costs, increased at a higher rate than revenue because of reduced level of subcontracting activity.

        The increase in operating income largely corresponded to the growth in revenue, net of subcontractor costs. Additionally, the increase resulted from improved project performance on a large environmental engineering and development project. The overall growth in operating income was partially offset by increased costs during the first half of fiscal 2009 on certain fixed-price projects caused by inclement weather, regulatory delays and subcontractor issues.

        Revenue and revenue, net of subcontractor costs, grew driven by increased demand for our services from the DoD, USAID and other U.S. federal government clients. Our acquisitions contributed approximately $27 million and $23 million in revenue and revenue, net of subcontractor costs, respectively. The overall growth was partially offset by a revenue decline in our state and local government business. Revenue, net of subcontractor costs, increased at a lower rate than revenue due to increased level of subcontracting activity on USAID and DoD projects in this segment.

        The increase in operating income substantially corresponded to the growth in revenue, net of subcontractor costs. On a percentage basis, operating margin increased as a result of improved project performance on certain fixed-price contracts and our focus on overhead cost control on discretionary expenses.

        Revenue and revenue, net of subcontractor costs, decreased due to weakness in the commercial business resulting from the slowdown in the real estate development and industrial markets. Our state and local government business also experienced a revenue decline caused by budget and spending constraints. The overall revenue decline was partially mitigated by demand for our engineering design services overseas from our international clients, increased project activity with the DoD and a full year of revenue in fiscal 2009 from acquisitions in late fiscal 2008. Revenue, net of subcontractor costs,

declined at a higher rate than revenue due to high level subcontracting activity on the international and DoD projects.

        Operating income decreased due largely to the decline in revenue, net of subcontractor costs. Additionally, we incurred $7.4 million in costs related to provisions for accounts receivable on certain real estate development and other commercial projects resulting from the continuing economic downturn. The decrease in operating income was partially mitigated by the reduction in overhead, labor and other employee-related expenses that corresponded to the revenue decline in this segment. The decrease was also partially offset by our aggressive focus on overhead cost reduction due to the continued revenue decline.

        Revenue declined due to the wind-down of Iraq-related projects, the completion of certain large contracts and the conclusion of a fiber-to-the-premise contract in the second quarter of fiscal 2008. Additionally, our state and local government business experienced a revenue decrease as a result of budget constraints. The overall decline was partially mitigated by demand for wind energy and water services from our commercial clients. Further, the revenue decline was partially offset by increased activity on BRAC, DOE and other U.S. federal government programs.

        The growth in revenue, net of subcontractor costs, was driven by demand for wind energy and water services from our commercial clients. Our U.S. federal government business also grew due to increased activity on BRAC, DOE and other U.S. federal government programs, largely offset by the wind-down of Iraq-related projects. Further, this segment's growth was partially offset by its revenue decline in the state and local government business as a result of budget constraints and the completion of certain large contracts, as well as the conclusion of a fiber-to-the-premise contract in the second quarter of fiscal 2008. The overall growth was also partially offset by reduced commercial activities in our telecommunications business.

        Operating income increased due largely to the growth in revenue, net of subcontractor costs. Further, the operating income benefited from favorable claim settlements and higher margins on certain commercial wind energy and water projects. The overall increase was partially offset by project start-up costs related to certain new programs, and $12.4 million in additional contract costs caused by inclement weather, subcontractor issues and scheduling delays and provisions for certain accounts receivable.

FINANCIAL CONDITION, LIQUIDITY AND CAPITAL RESOURCES

        Capital Requirements.    Our capital requirements are to fund working capital needs, capital expenditures and debt services requirements, as well as to fund acquisitions. We believe that our cash balance, operating cash flow and available borrowing under the credit agreement described below will be sufficient to meet our capital requirements for at least the next 12 months.

        Operating Activities.    For fiscal 2010, net cash provided by operating activities was $106.8 million, a decrease of $91.4 million, or 46.1%, compared to fiscal 2009. The decrease resulted primarily from a $40 million IRS tax settlement refund and substantial cash collections on certain large commercial fixed-price contracts in fiscal 2009. To a lesser extent, the net cash provided by operating activities declined due to a reduction in advance payments received on contract work. The overall decrease was partially mitigated by more favorable changes in accounts payable, accrued compensation, prepaid expenses and deferred income taxes compared to fiscal 2009, as a result of the timing of payments to vendors, subcontractors, employees and the taxing authorities.

        Investing Activities.    For fiscal 2010, net cash used in investing activities was $97.4 million, a decrease of $35.9 million compared to fiscal 2009. Cash payments for business acquisitions were $78.9 million in fiscal 2010, a decrease of $35.8 million compared to fiscal 2009. Our capital expenditures were $21.6 million, an increase of $1.8 million compared to fiscal 2009. New equipment was purchased to replace obsolete equipment and satisfy requirements for project execution.

        Financing Activities.    For fiscal 2010, net cash provided by financing activities was $121.4 million, an increase of $149.5 million compared to net cash used in financing activities for fiscal 2009. The increase resulted from $120 million in borrowings under our credit agreement at the end of fiscal 2010 to fund the acquisition of BPR and working capital needs in the first quarter of fiscal 2011. Also, in the prior year we had a net debt payment of $50.4 million. The increase was partially offset by a decline in proceeds from the issuance of common stock upon the exercise of stock options.

        Debt Financing.    Under our credit agreement, our revolving credit facility ("Facility") is $300.0 million, and the term of the agreement extends through March 30, 2012. As part of the Facility, we may request financial letters of credit up to an aggregate sum of $50.0 million and standby letters of credit up to the full amount of the Facility. As of October 3, 2010, we had $120 million in borrowings outstanding, $27.8 million in standby letters of credit and $152.2 million in availability under the Facility. In October 2010, we entered into an amendment of the credit agreement to provide additional flexibility and to clarify certain administrative matters with respect to potential future acquisitions. The amendment resulted in an interest rate increase of 0.25% per annum.

        The credit agreement requires us to comply with various financial and operating covenants. Specifically, (i) the maximum consolidated leverage ratio (defined as the ratio of funded debt to rolling four-quarter adjusted earnings before interest, tax, depreciation and amortization ("EBITDA") is 2.5x for each quarter, and (ii) the minimum fixed charge coverage ratio (as defined in the credit agreement) is 1.25x for each quarter. As of October 3, 2010, our consolidated leverage ratio was 1.2x, and our fixed charge coverage ratio was 2.71x. Further, the credit agreement contains other restrictions, including but not limited to, the creation of liens and the payment of dividends on our capital stock (other than stock dividends). Borrowings under the credit agreement are collateralized by our accounts receivable, the stock of our significant subsidiaries and our cash, deposit accounts, investment property and financial assets.

        Inflation.    We believe our operations have not been, and, in the foreseeable future, are not expected to be, materially adversely affected by inflation or changing prices due to the average duration of our projects and our ability to negotiate prices as contracts end and new contracts begin.

We are unable to reasonably predict the timing of tax settlements, as tax audits can involve complex issues and the resolution of those issues may span multiple years, particularly if subject to negotiation or litigation. For more information, see Note 6 "Income Taxes" of the "Notes to Consolidated Financial Statements" included in Item 8.


CRITICAL ACCOUNTING POLICIES

        The preparation of consolidated financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions in the application of certain accounting policies that affect amounts reported in our consolidated financial statements and related footnotes included in Item 8 of this report. In order to understand better the changes that may occur to key elements of our financial condition, results of operations and cash flows, readers should be aware of the critical accounting policies we apply and estimates we use in preparing our consolidated financial statements. Although such estimates and assumptions are based on management's best knowledge of current events and actions the Company may undertake in the future, actual results could differ materially from those estimates.

        Our significant accounting policies are described in the "Notes to Consolidated Financial Statements" included in Item 8. Highlighted below are the accounting policies that management considers most critical to investors' understanding of our financial results and condition, and that require complex judgments by management.


Revenue Recognition and Contract Costs

        We recognize revenue for most of our contracts using the percentage-of-completion method, primarily based on contract costs incurred to date compared to total estimated contract costs. We generally utilize the cost-to-cost approach to estimate the progress towards completion in order to

62


Table of Contents


determine the amount of revenue and profit to recognize. This method of revenue recognition requires us to prepare estimates of cost to complete contracts in progress. In making such estimates, judgments are required to evaluate contingencies such as potential variances in schedule; the cost of materials and labor productivity; and the impact of change orders, liability claims, contract disputes and achievement of contractual performance standards. Changes in total estimated contract cost and losses, if any, could materially impact our results of operations or financial position. Certain of our contracts are service-related contracts, such as providing operations and maintenance services or a variety of technical assistance services. Our service contracts are accounted for using the proportional performance method under which revenue is recognized in proportion to the number of service activities performed, in proportion to the direct costs of performing the service activities, or evenly across the period of performance depending upon the nature of the services provided.

        We recognize revenue for work performed under three major types of contracts: fixed-price, time-and-materials and cost-plus.

        Fixed-Price.    We enter into two major types of fixed-price contracts: firm fixed-price ("FFP") and fixed-price per unit ("FPPU"). Under FFP contracts, our clients pay us an agreed fixed-amount negotiated in advance for a specified scope of work. We generally recognize revenue on FFP contracts using the percentage-of-completion method. If the nature or circumstances of the contract prevent us from preparing a reliable estimate at completion, we will delay profit recognition until adequate information about the contract's progress becomes available. Under our FPPU contracts, clients pay us a set fee for each service or production transaction that we complete. Accordingly, we recognize revenue under FPPU contracts as we complete the related service or production transactions, generally using the proportional performance method.

        Time-and-Materials.    Under time-and-materials contracts, we negotiate hourly billing rates and charge our clients based on the actual time that we spend on a project. In addition, clients reimburse us for our actual out-of-pocket costs of materials and other direct incidental expenditures that we incur in connection with our performance under the contract. The majority of our time-and-material contracts are subject to maximum contract values and, accordingly, revenue under these contracts is generally recognized under the percentage-of-completion method. However, time and materials contracts that are service-related contracts are accounted for utilizing the proportional performance method. Revenue on contracts that are not subject to maximum contract values is recognized based on the actual number of hours we spend on the projects plus any actual out-of-pocket costs of materials and other direct incidental expenditures that we incur on the projects. Our time-and-materials contracts also generally include annual billing rate adjustment provisions.

        Cost-Plus.    Under cost-plus contracts, we are reimbursed for allowable or otherwise defined costs incurred plus a fee or mark-up. The contracts may also include incentives for various performance criteria, including quality, timeliness, ingenuity, safety and cost-effectiveness. In addition, our costs are generally subject to review by our clients and regulatory audit agencies, and such reviews could result in costs being disputed as non-reimbursable under the terms of the contract. Revenue for cost-plus contracts is recognized at the time services are performed based upon the amounts we expect to realize using the percentage-of-completion method. Revenue is not recognized for non-recoverable costs. In situations where an audit indicates that we may have billed a client for costs not allowable under the terms of the contract, we estimate the amount of such non-billable costs and adjust our revenue accordingly. Performance incentives are included in our estimates of revenue when their realization is reasonably assured.

        If estimated total costs on any contract indicate a loss, we recognized the entire estimated loss in the period the loss becomes known. The cumulative effect of revisions to revenue, estimated costs to complete contracts, including penalties, incentive awards, change orders, claims, anticipated losses and others are recorded in the period in which the revisions are identified and the loss can be reasonably

63


Table of Contents


estimated. Such revisions could occur in any reporting period and the effects may be material depending on the size of the project or the adjustment.

        Once contract performance is underway, we may experience changes in conditions, client requirements, specifications, designs, materials and expectations regarding the period of performance. Such changes are "change orders" and may be initiated by us or by our clients. In many cases, agreement with the client as to the terms of change orders is reached prior to work commencing; however, sometimes circumstances require that work progress without obtaining client agreement. Costs related to change orders are recognized as incurred. Revenue attributable to change orders that are unapproved as to price or scope is recognized to the extent that costs have been incurred if the amounts can be reliably estimated and their realization is probable. Contract profits on these unapproved change orders are recognized only when realization is assured beyond a reasonable doubt. Change orders that are unapproved as to both price and scope are evaluated as claims.

        Claims are amounts in excess of agreed contract prices that we seek to collect from our clients or others for delays, errors in specifications and designs, contract terminations, change orders in dispute or unapproved as to both scope and price or other causes of unanticipated additional costs. Revenue on claims is recognized only to the extent that contract costs related to the claims have been incurred and when it is probable that the claim will result in a bona fide addition to contract value that can be reliably estimated. No profit is recognized on a claim until final settlement occurs. This can lead to a situation in which costs are recognized in one period and revenue is recognized in a subsequent period when a client agreement is obtained or a claims resolution occurs.


Insurance Matters, Litigation and Contingencies

        In the normal course of business, we are subject to certain contractual guarantees and litigation. Generally, such guarantees relate to project schedules and performance. Most of the litigation involves us as a defendant in contractual disagreements, workers' compensation, personal injury and other similar lawsuits. We maintain insurance coverage for various aspects of our business and operations. However, we have elected to retain a portion of losses that may occur through the use of various deductibles, limits and retentions under our insurance programs. This practice may subject us to some future liability for which we are only partially insured or are completely uninsured.

        We record in our consolidated balance sheets amounts representing our estimated liability for self-insurance claims. We utilize actuarial analyses to assist in determining the level of reserves to establish for our employee medical and workers compensation self-insurance claims that are known and have been asserted against us, as well as for self-insurance claims that are believed to have been incurred based on actuarial analysis but have not yet been reported to our claims administrators as of the balance sheet date. We include any adjustments to such insurance reserves in our consolidated results of operations.

        Except as described in Note 15 of the "Notes to Consolidated Financial Statements" included in Item 8, we have not been affected by any litigation or other contingencies that have had, or are currently anticipated to have, a material impact on our results of operations or financial position. As additional information about current or future litigation or other contingencies becomes available, management will assess whether such information warrants the recording of additional expenses relating to those contingencies. Such additional expenses could potentially have a material impact on our results of operations and financial position.


Stock-Based Compensation

        Our stock-based compensation plans include stock options, restricted stock and an employee stock purchase plan for our eligible employees and outside directors. Stock-based compensation cost is measured at the grant date based on the fair value of the award and is recognized as expense over the

64


Table of Contents


requisite service period. Determining the fair value of stock-based awards at the grant date requires management to make assumptions and apply judgment to determine the fair value of our awards. These assumptions and judgments include estimating the future volatility of our stock price, future employee turnover rates, future stock option exercise behaviors and, for performance based awards, the achievement of company performance goals. Our stock-based compensation expense was $10.2 million, $9.4 million and $8.3 million for fiscal 2010, 2009 and 2008, respectively. Actual results could materially differ from these estimates and our results of operations could be materially impacted.


Goodwill and Business Combinations

        The cost of an acquired company is assigned to the tangible and intangible assets purchased and the liabilities assumed on the basis of their fair values at the date of acquisition. The determination of fair values of assets and liabilities acquired requires us to make estimates and use valuation techniques when market value is not readily available. Any excess of purchase price over the fair value of net tangible and intangible assets acquired is allocated to goodwill. Goodwill typically represents the value paid for the assembled workforce and enhancement of our service offerings. Effective September 28, 2009, our transaction costs associated with business combinations are expensed as they are incurred instead of being capitalized as part of the cost of the acquisition.

        Identifiable intangible assets include backlog, non-compete agreements, client relations, trade names, patents and other assets. The costs of these intangible assets are amortized over their contractual or economic lives, which range from two to seven years. We assess the recoverability of the unamortized balance of our intangible assets when indicators of impairment are present based on expected future profitability and undiscounted expected cash flows and their contribution to our overall operations. Should the review indicate that the carrying value is not fully recoverable, the excess of the carrying value over the fair value of the intangible assets would be recognized as an impairment loss.

        We perform our annual goodwill impairment review at the beginning of our fiscal fourth quarter. Our annual review as of June 28, 2010 (i.e., the first day of our fiscal fourth quarter), indicated that we had no impairment of goodwill, and all of our reporting units had estimated fair values that were substantially in excess of their carrying values, including goodwill. In addition, we regularly evaluate whether events and circumstances have occurred that may indicate a potential change in recoverability of goodwill. We perform interim goodwill impairment reviews between our annual reviews if certain events and circumstances have occurred, including a significant adverse change in the business climate, unanticipated competition or a loss of key personnel. We believe the methodology that we use to review impairment of goodwill, which includes a significant amount of judgment and estimates, provides us with a reasonable basis to determine whether an impairment has occurred. However, many of the factors employed in determining whether our goodwill is impaired are outside of our control and it is reasonably likely that assumptions and estimates will change in future periods. These changes could result in future impairments.

        The goodwill impairment review involves the determination of the fair value of our reporting units, which for us are the components one level below our reportable segments. This process requires us to make significant judgments and estimates, including assumptions about our strategic plans with regard to our operations as well as the interpretation of current economic indicators and market valuations. Furthermore, the development of the present value of future cash flow projections includes assumptions and estimates derived from a review of our expected revenue growth rates, profit margins, business plans, cost of capital and tax rates. We also make certain assumptions about future market conditions, market prices, interest rates and changes in business strategies. Changes in assumptions or estimates could materially affect the determination of the fair value of a reporting unit. This could eliminate the excess of fair value over carrying value of a reporting unit entirely and, in some cases, result in impairment. Such changes in assumptions could be caused by a loss of one or more significant contracts, reductions in government or commercial client spending, or a decline in the demand for our

services due to changing economic conditions. In the event that we determine that our goodwill is impaired, we would be required to record a non-cash charge that could result in a material adverse effect on our results of operations or financial position.

        We utilize two methods to determine the fair value of our reporting units: (i) the Income Approach and (ii) the Market Approach. While each of these approaches is initially considered in the valuation of the business enterprises, the nature and characteristics of the reporting units indicate which approach is most applicable. The Income Approach utilizes the discounted cash flow method, which focuses on the expected cash flow of the reporting unit. In applying this approach, the cash flow available for distribution is calculated for a finite period of years. Cash flow available for distribution is defined, for purposes of this analysis, as the amount of cash that could be distributed as a dividend without impairing the future profitability or operations of the reporting unit. The cash flow available for distribution and the terminal value (the value of the reporting unit at the end of the estimation period) are then discounted to present value to derive an indication of the value of the business enterprise. The Market Approach is comprised of the guideline company method and the similar transactions method. The guideline company method focuses on comparing the reporting unit to select reasonably similar (or "guideline") publicly traded companies. Under this method, valuation multiples are (i) derived from the operating data of selected guideline companies; (ii) evaluated and adjusted based on the strengths and weaknesses of the reporting units relative to the selected guideline companies; and (iii) applied to the operating data of the reporting unit to arrive at an indication of value. In the similar transactions method, consideration is given to prices paid in recent transactions that have occurred in the reporting unit's industry or in related industries. For our annual impairment analysis as of June 28, 2010, we weighted the Income Approach and the Market Approach at 70% and 30%, respectively. The Income Approach was given a higher weight because it has the most direct correlation to the specific economics of the reporting unit, as compared to the Market Approach, which is based on multiples of broad-based (i.e., less comparable) companies.

        Certain of our acquisition agreements include contingent earn-out payments, which are generally based on the achievement of future operating income. For fiscal 2010 acquisitions, we estimated the fair value of contingent earn-out payments, and recorded the estimated fair value of contingent consideration as a liability in "Other current liabilities" and "Other long-term liabilities" on our consolidated balance sheet as of October 3, 2010. On a quarterly basis, we review and determine the fair value of the contingent consideration, and the updated fair value could differ materially from those initial estimates. Any adjustments are recorded in earnings. Ultimately, the liability will be adjusted to the amount paid, and the difference between our initial estimates and amounts paid will be recorded in earnings. As of October 3, 2010, our liability for contingent consideration was $20.5 million, representing our current estimate of the fair value of a maximum obligation of $26.5 million. The remaining contingent earn-outs from acquisitions in prior fiscal years will be recorded as additions to goodwill if paid.


Income Taxes

        We file a consolidated U.S. federal income tax return and combined California franchise tax return. In addition, we file other returns that are required in the states and jurisdictions in which we do business. We account for certain income and expense items differently for financial reporting and income tax purposes. Deferred tax assets and liabilities are computed for the differences between the financial statement and tax bases of assets and liabilities that will result in taxable or deductible amounts in the future based on enacted tax laws and rates applicable to the periods in which the differences are expected to reverse. In determining the need for a valuation allowance on deferred tax assets, management reviews both positive and negative evidence, including current and historical results of operations, future income projections and potential tax planning strategies. Although realization is not assured, based on our assessment, we have concluded that it is more likely than not that the assets,

66


Table of Contents


other than substantially all of our deferred tax assets related to capital loss carry-forwards, will be realized.

        According to the authoritative guidance on accounting for uncertainty in income taxes, we may recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position should be measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. For more information related to our unrecognized tax benefits, see Note 6 "Income Taxes" of the "Notes to Consolidated Financial Statements" included in Item 8.


RECENT ACCOUNTING PRONOUNCEMENTS

        For a discussion of recent accounting standards and the effect they could have on our consolidated financial statements, see Note 2 "Basis of Presentation and Preparation" included in Part II, Item 8, "Financial Statements and Supplementary Data".

Item 7A.    Quantitative and Qualitative Disclosures About Market Risk

        We do not enter into derivative financial instruments for trading or speculation purposes. In the normal course of business, we have exposure to both interest rate risk and foreign currency transaction and translation risk, primarily related to the Canadian dollar.

        We are exposed to interest rate risk under our credit agreement. We may borrow on our Facility, at our option, at either (a) a base rate (the greater of the U.S. federal funds rate plus 0.50% per annum or the bank's reference rate) plus a margin which ranges from 0.25% to 1.50% per annum, or (b) a Eurodollar rate plus a margin that ranges from 1.25% to 2.50% per annum. Borrowings at the base rate have no designated term and may be repaid without penalty any time prior to the Facility's maturity date. Borrowings at a Eurodollar rate have a term no less than 30 days and no greater than 90 days. Typically, at the end of such term, such borrowings may be rolled over at our discretion into either a borrowing at the base rate or a borrowing at a Eurodollar rate with similar terms, not to exceed the maturity date of the Facility. The Facility matures on March 30, 2012, or earlier at our discretion upon payment in full of loans and other obligations. As of October 3, 2010, we had $120 million in borrowings outstanding under the Facility at a weighted average interest rate of 1.44% per annum.

        Most of our transactions are in U.S. dollars; however, some of our subsidiaries conduct business in foreign currencies, primarily the Canadian dollar. Therefore, we are subject to currency exposure and volatility because of currency fluctuations. We attempt to minimize our exposure to these fluctuations by matching revenue and expenses in the same currency for our contracts. For fiscal 2010 and 2009, our foreign currency gains and losses were immaterial.

        We have foreign currency exchange rate exposure in our stockholders' equity primarily as a result of the currency translation related to our subsidiary in Canada where the local currency is the functional currency. To the extent the U.S. dollar strengthens against the Canadian dollar, the translation of these foreign currency denominated transactions will result in the reduced revenue, operating expenses, assets and liabilities. Similarly, our revenue, operating expenses, assets and liabilities will increase if the U.S. dollar weakens against the Canadian dollar. The effect of foreign exchange rate translation on our consolidated balance sheet for fiscal 2010 was a net foreign translation gain of $6.9 million. The gain was recognized as an adjustment to stockholders' equity through other comprehensive income.

        In the first quarter of fiscal 2010, we entered into three foreign currency forward contracts to manage foreign currency exposure related to interest income on an intercompany note denominated in

67


Table of Contents


Canadian dollars ("CAD"). In the second quarter of fiscal 2010, we settled the first foreign currency forward contract for U.S. $3.9 million. We also entered into a new forward contract for CAD $4.2 million (equivalent to U.S. $3.9 million at date of inception) that matures on January 28, 2013. For more information, see Note 14 "Fair Value of Derivative Instruments" of the "Notes to Consolidated Financial Statements".

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders of Tetra Tech, Inc.:

        In our opinion, the accompanying consolidated balance sheets and the related consolidated statements of income, of stockholders' equity and of cash flows present fairly, in all material respects, the financial position of Tetra Tech, Inc. and its subsidiaries as of October 3, 2010 and September 27, 2009, and the results of their operations and their cash flows for each of the three years in the period ended October 3, 2010, in conformity with accounting principles generally accepted in the United States of America. In addition, in our opinion, the financial statement schedule listed in the accompanying index presents fairly, in all material respects, the information set forth therein when read in conjunction with the related consolidated financial statements. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of October 3, 2010, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company's management is responsible for these financial statements and the financial statement schedule, for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in Management's Report on Internal Control over Financial Reporting, appearing under Item 9A of this Form 10-K. Our responsibility is to express opinions on these financial statements, on the financial statement schedule, and on the Company's internal control over financial reporting based on our integrated audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

        As discussed in Note 2 to the consolidated financial statements, the Company changed its method of accounting for business combinations as of September 28, 2009.

        A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

        Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

TETRA TECH, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Description of Business

        Tetra Tech, Inc. and its wholly owned subsidiaries ("we," "us," "our" or the "Company") is a leading provider of consulting, engineering, program management, construction management and technical services focusing on resource management, infrastructure and the environment. We typically begin at the earliest stage of a project by applying science to problems and developing solutions tailored to our clients' needs and resources. Our solutions may span the entire life cycle of the project and include applied science, research and technology, engineering, design, construction management, construction, operations and maintenance, and information technology.

2. Basis of Presentation and Preparation

        Principles of Consolidation and Presentation.    The accompanying consolidated financial statements include the accounts of Tetra Tech, Inc. and its wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation.

        In fiscal 2010, we discontinued reporting "Revenue, net of subcontractor costs" and "Gross profit" on our consolidated statements of income. Additionally, "Other contract costs" have been relabeled as "Other costs of revenue" and "Long-term obligations" have been relabeled as "Long-term debt". In October 2010, our former "Environmental Consulting Services" segment was renamed the "Engineering and Consulting Services" segment.

        Fiscal Year.    We report results of operations based on 52 or 53-week periods ending near September 30 of each year. Fiscal years 2010, 2009 and 2008 contained 53, 52 and 52 weeks, respectively.

        Use of Estimates.    The preparation of financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions. These estimates and assumptions affect the amounts reported in our consolidated financial statements and accompanying notes. Although such estimates and assumptions are based on management's best knowledge of current events and actions we may take in the future, actual results could differ materially from those estimates.

        Revenue Recognition and Contract Costs.    We recognize revenue for most of our contracts using the percentage-of-completion method, primarily based on contract costs incurred to date compared to total estimated contract costs. We generally utilize the cost-to-cost approach to estimate the progress towards completion in order to determine the amount of revenue and profit to recognize. Certain of our contracts are service-related contracts, such as providing operations and maintenance services or a variety of technical assistance services. Our service contracts are accounted for using the proportional performance method under which revenue is recognized in proportion to the number of service activities performed, in proportion to the direct costs of performing the service activities, or evenly across the period of performance depending upon the nature of the services provided.

        We recognize revenue for work performed under three major types of contracts: fixed-price, time-and-materials and cost-plus.

        Fixed-Price.    We enter into two major types of fixed-price contracts: FFP and FPPU. Under FFP contracts, our clients pay us an agreed fixed-amount negotiated in advance for a specified scope of work. We generally recognize revenue on FFP contracts using the percentage-of-completion method. If the nature or circumstances of the contract prevent us from preparing a reliable estimate at completion, we will delay profit recognition until adequate information about the contract's progress

75

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

2. Basis of Presentation and Preparation (Continued)


becomes available. Under our FPPU contracts, clients pay us a set fee for each service or production transaction that we complete. Accordingly, we recognize revenue under FPPU contracts as we complete the related service or production transactions, generally using the proportional performance method.

        Time-and-Materials.    Under time-and-materials contracts, we negotiate hourly billing rates and charge our clients based on the actual time that we spend on a project. In addition, clients reimburse us for our actual out-of-pocket costs for materials and other direct incidental expenditures that we incur in connection with our performance under the contract. The majority of our time-and-material contracts are subject to maximum contract values and, accordingly, revenue under these contracts is generally recognized under the percentage-of-completion method. However, time and materials contracts that are service-related contracts are accounted for utilizing the proportional performance method. Revenue on contracts that are not subject to maximum contract values is recognized based on the actual number of hours we spend on the projects plus any actual out-of-pocket costs of materials and other direct incidental expenditures that we incur on the projects. Our time-and-materials contracts also generally include annual billing rate adjustment provisions.

        Cost-Plus.    Under cost-plus contracts, we are reimbursed for allowable or otherwise defined costs incurred plus a fee or mark-up. The contracts may also include incentives for various performance criteria, including quality, timeliness, ingenuity, safety and cost-effectiveness. In addition, our costs are generally subject to review by our clients and regulatory audit agencies, and such reviews could result in costs being disputed as non-reimbursable under the terms of the contract. Revenue for cost-plus contracts is recognized at the time services are performed based upon the amounts we expect to realize using the percentage-of-completion method. Revenue is not recognized for non-recoverable costs. In situations where an audit indicates that we may have billed a client for costs not allowable under the terms of the contract, we estimate the amount of such non-billable costs and adjust our revenue accordingly. Performance incentives are included in our estimates of revenue when their realization is reasonably assured.

        If estimated total costs on any contract indicate a loss, we recognize the entire estimated loss in the period the loss becomes known. The cumulative effect of revisions to revenue, estimated costs to complete contracts, including penalties, incentive awards, change orders, claims, anticipated losses and others are recorded in the period in which the revisions are identified and the loss can be reasonably estimated. Such revisions could occur in any reporting period and the effects may be material depending on the size of the project or the adjustment.

        Once contract performance is underway, we may experience changes in conditions, client requirements, specifications, designs, materials and expectations regarding the period of performance. Such changes are "change orders" and may be initiated by us or by our clients. In many cases, agreement with the client as to the terms of change orders is reached prior to work commencing; however, sometimes circumstances require that work progress without obtaining client agreement. Costs related to change orders are recognized as incurred. Revenue attributable to change orders that are unapproved as to price or scope is recognized to the extent that costs have been incurred if the amounts can be reliably estimated and their realization is probable. Contract profits on these unapproved change orders are recognized only when realization is assured beyond a reasonable doubt. Change orders that are unapproved as to both price and scope are evaluated as claims.

        Claims are amounts in excess of agreed contract prices that we seek to collect from our clients or others for delays, errors in specifications and designs, contract terminations, change orders in dispute or

76

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

2. Basis of Presentation and Preparation (Continued)


unapproved as to both scope and price or other causes of unanticipated additional costs. Revenue on claims is recognized only to the extent that contract costs related to the claims have been incurred and when it is probable that the claim will result in a bona fide addition to contract value that can be reliably estimated. No profit is recognized on a claim until final settlement occurs. This can lead to a situation in which costs are recognized in one period and revenue is recognized in a subsequent period when a client agreement is obtained or a claims resolution occurs.

        Cash and Cash Equivalents.    Cash equivalents include all highly liquid investments with maturities of 90 days or less at the date of purchase.

        Accounts Receivable—Net.    Net accounts receivable is primarily comprised of billed and unbilled accounts receivable, contract retentions and allowances for doubtful accounts. Billed accounts receivable represent amounts billed to clients that have not been collected. Unbilled accounts receivable represent revenue recognized but not yet billed pursuant to contract terms or billed after the period end date. Substantially all unbilled receivables as of October 3, 2010 are expected to be billed and collected within 12 months. Contract retentions represent amounts withheld by clients until certain conditions are met or the project is completed, which may be several months or years. Allowances for doubtful accounts represent the amounts that may become uncollectible or unrealizable in the future. We determine an estimated allowance for uncollectible accounts based on management's judgment regarding our operating performance related to the adequacy of the services performed or products delivered, the status of change orders and claims, our experience settling change orders and claims, and the financial condition of our clients.

        We record provisions for estimated losses on uncompleted contracts in the period in which they become known. The cumulative effects of revisions to contract revenues and estimated completion costs are recorded in the accounting period in which the amounts become evident and can be reasonably estimated. These revisions can include such items as the effects of change orders and claims, warranty claims, liquidated damages or other contractual penalties, adjustments for audit findings on U.S. or other government contracts and contract closeout settlements.

        Billings in excess of costs on uncompleted contracts represent the amounts of cash collected from clients and billings to clients on contracts in advance of work performed and revenue recognized. The majority of these amounts will be earned within 12 months.

        Property and Equipment.    Property and equipment are recorded at cost and are depreciated over their estimated useful lives using the straight-line method. The cost of property and equipment sold or otherwise disposed of and the related accumulated depreciation are removed from the accounts, and any gain (loss) on disposal is reflected in the consolidated statements of income. Expenditures for maintenance and repairs are expensed as incurred. Generally, estimated useful lives range from three to ten years for equipment, furniture and fixtures. Leasehold improvements are amortized on a straight-line basis over the shorter of their estimated useful lives or the length of the lease.

        Long-Lived Assets.    Our policy regarding long-lived assets is to evaluate the recoverability of our assets when the facts and circumstances suggest that the assets may be impaired. This assessment is performed based on the estimated undiscounted cash flows compared to the carrying value of the assets. If the future cash flows (undiscounted and without interest charges) are less than the carrying value, a write-down would be recorded to reduce the related asset to its estimated fair value.

2. Basis of Presentation and Preparation (Continued)

        Business Combinations.    The cost of an acquired company is assigned to the tangible and intangible assets purchased and the liabilities assumed on the basis of their fair values at the date of acquisition. The determination of fair values of assets and liabilities acquired requires us to make estimates and use valuation techniques when market value is not readily available. Any excess of purchase price over the fair value of net tangible and intangible assets acquired is allocated to goodwill. Goodwill typically represents the value paid for the assembled workforce and enhancement of our service offerings. Beginning in fiscal 2010, the transaction costs associated with business combinations are expensed as they are incurred instead of being capitalized as part of the cost of the acquisitions.

        Certain of our acquisition agreements include contingent earn-out payments, which are generally based on the achievement of future operating income. For fiscal 2010 acquisitions, we estimated the fair value of contingent earn-out payments, and recorded the estimated fair value of contingent consideration as a liability in "Other current liabilities" and "Other long-term liabilities" on our consolidated balance sheet as of October 3, 2010. On a quarterly basis, we review and determine the fair value of the contingent consideration, and the updated fair value could differ materially from those initial estimates. Any adjustments are recorded in earnings. Ultimately, the liability will be adjusted to the amount paid, and the difference between our initial estimates and amounts paid will be recorded in earnings.

        Goodwill and Intangibles.    Goodwill represents the excess of the aggregate purchase price over the fair value of the net assets acquired in a business acquisition. Following an acquisition, we perform an analysis to value the acquired company's tangible and identifiable intangible assets and liabilities. With respect to identifiable intangible assets, we consider backlog, non-compete agreements, client relations, trade names, patents and other assets. The costs of these intangible assets are amortized using the straight-line method over their contractual or economic lives, which range from two to seven years. We assess the recoverability of the unamortized balance of our intangible assets when indicators of impairment are present based on expected future profitability and undiscounted expected cash flows and their contribution to our overall operations. Should the review indicate that the carrying value is not fully recoverable, the excess of the carrying value over the fair value of the intangible assets would be recognized as an impairment loss.

        We test our goodwill for impairment on an annual basis, and more frequently when an event occurs or circumstances indicate that the carrying value of the asset may not be recoverable. We believe the methodology that we use to review impairment of goodwill, which includes a significant amount of judgment and estimates, provides us with a reasonable basis to determine whether an impairment has occurred. However, many of the factors employed in determining whether our goodwill is impaired are outside of our control and it is reasonably likely that assumptions and estimates will change in future periods. These changes could result in future impairments.

        We perform our annual goodwill testing on the first day of our fiscal fourth quarter (June 28, 2010, in fiscal 2010). Our reporting units for goodwill impairment testing are the components one level below our reportable segments. The annual impairment test for goodwill is a two-step process involving the comparison of the estimated fair value of each reporting unit to the reporting unit's carrying value, including goodwill. If the fair value of a reporting unit exceeds its carrying amount, the goodwill of the reporting unit is not considered impaired; therefore, the second step of the impairment test is unnecessary. If the carrying amount of a reporting unit exceeds its fair value, we perform the second step of the goodwill impairment test to measure the amount of impairment loss to be recorded. If our

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

2. Basis of Presentation and Preparation (Continued)


goodwill were impaired, we would be required to record a non-cash charge that could have a material adverse effect on our consolidated financial statements.

        Stock-Based Compensation.    We recognize the fair value of our stock-based compensation awards as compensation expense on a straight-line basis over the requisite service period of the award (or to an employee's eligible retirement date, if earlier). We estimate the fair value of options and stock purchase rights granted using the Black-Scholes option pricing model. The fair value of restricted stock grants is estimated at the grant date using the market price of the underlying common stock at the date of grant. The assumptions used in computing the fair value of stock-based payments reflect our estimates, but involve uncertainties relating to market and other conditions, many of which are outside of our control. We estimate expected volatility based on historical daily price changes of our stock for a period that approximates the current expected term of the awards, in addition to recent option market activity. For performance based awards, our expected performance is reviewed to determine the percentage of shares that will vest in accordance with our Executive Compensation Policy. The expected term is the number of years we estimate that the award will be outstanding prior to exercise considering vesting schedules and our historical exercise patterns.

        Deferred Compensation.    We maintain a non-qualified defined contribution supplemental retirement plan for certain key employees that is accounted for in accordance with applicable authoritative guidance on accounting for deferred compensation arrangements where amounts earned are held in a rabbi trust and invested. Employee deferrals and our match are deposited into a rabbi trust, and the funds are generally invested in individual variable life insurance contracts that we own and are specifically designed to informally fund savings plans of this nature. Our consolidated balance sheets reflect our investment in variable life insurance contracts in "Other assets". Our obligation to participating employees is reflected in "Other long-term liabilities". All income and expenses related to the rabbi trust are reflected in our consolidated statements of income.

        Selling, General and Administrative Expenses.    SG&A expenses represent overhead expenses that are not associated with contract execution and are expensed in the period incurred. SG&A expenses are comprised primarily of marketing and bid and proposal costs, and our corporate headquarters' costs related to the executive offices, finance, accounting, administration and information technology. Additionally, we include in our SG&A expenses the amortization of identifiable intangible assets.

        Income Taxes.    We file a consolidated U.S. federal income tax return and combined California franchise tax return. In addition, we file other returns that are required in the states and jurisdictions in which we do business. We account for certain income and expense items differently for financial reporting and income tax purposes. Deferred tax assets and liabilities are computed for the difference between the financial statement and tax bases of assets and liabilities that will result in taxable or deductible amounts in the future based on enacted tax laws and rates applicable to the periods in which the differences are expected to reverse. In determining the need for a valuation allowance, management reviews both positive and negative evidence, including current and historical results of operations, future income projections and potential tax planning strategies.

        According to the authoritative guidance on accounting for uncertainty in income taxes, we may recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position should be

measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. This guidance also addresses de-recognition, classification, interest and penalties on income taxes, accounting in interim periods and disclosure requirements for uncertain tax positions.

        Earnings Per Share.    Basic earnings per share ("EPS") is computed by dividing net income available to common stockholders by the weighted-average number of common shares outstanding, less unvested restricted stock. Diluted EPS is computed by dividing net income by the weighted-average number of common shares outstanding and dilutive potential common shares for the period. Potential common shares include the weighted-average dilutive effects of outstanding stock options and unvested restricted stock using the treasury stock method.

        Fair Value of Financial Instruments.    The carrying amounts of cash and cash equivalents, accounts receivable and accounts payable approximate fair value because of the short maturities of these instruments. Any borrowings under our revolving credit facility approximate fair value because the interest rates are based upon variable reference rates. Certain other assets and liabilities, such as contingent earn-out payable and forward foreign exchange contracts that we purchased as cash-flow hedges, are required to be carried in our consolidated financial statements at fair value.

        Concentration of Credit Risk.    Financial instruments that subject us to credit risk consist primarily of cash and cash equivalents and net accounts receivable. We place our temporary cash investments with lower risk financial institutions and, by policy, limit the amount of investment exposure to any one financial institution. Approximately 37% and 35% of accounts receivable was due from various agencies of the U.S. federal government at fiscal 2010 and 2009 year-ends, respectively. The remaining accounts receivable are generally diversified due to the large number of organizations comprising our client base and their geographic dispersion. We perform ongoing credit evaluations of our clients and maintain an allowance for potential credit losses.

        Foreign Currency Translation.    We determine the functional currency of our foreign operating units based upon the primary currency in which they operate. These operating units maintain their accounting records in their local currency, primarily Canadian dollars. Where the functional currency is not the U.S. dollar, translation of assets and liabilities to U.S. dollars is based on exchange rates at the balance sheet date. Translation of revenue and expenses to U.S. dollars is based on the average rate during the period. Translation gains or losses are reported as a component of other comprehensive income (loss). Gains or losses from foreign currency transactions are included in results of operations, with the exception of intercompany foreign transactions that are considered long-term investments, which are recorded in "Accumulated other comprehensive income" on our consolidated balance sheets.

        Recently Adopted Accounting Standards.    On September 28, 2009, we adopted authoritative guidance for business combinations. The guidance retains the fundamental requirements that companies use the acquisition method of accounting (previously referred to as the purchase method of accounting) for all business combinations, but introduced a number of changes, including the way assets and liabilities are valued, recognized and measured as a result of business combinations. The guidance requires an acquisition date fair value measurement of assets acquired and liabilities assumed including contingent consideration. It also requires the fair value capitalization of in-process research and development, and requires transaction-related costs to be expensed as incurred. Adoption of the guidance applied to all acquisitions consummated in fiscal 2010, but did not affect our accounting for acquisitions made in

80

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

2. Basis of Presentation and Preparation (Continued)


prior fiscal years. Transaction-related costs were expensed in fiscal 2010 and have been recorded in SG&A expenses.

        On September 28, 2009, we adopted authoritative guidance that changes the accounting and reporting for non-controlling interests. Non-controlling interests are now reported as components of equity separate from the parent's equity, and purchases or sales of equity interests that do not result in a change in control are to be accounted for as equity transactions. In addition, net income attributable to a non-controlling interest is now included in net income, and upon a loss of control, the interest sold, as well as any interest retained, is now recorded at fair value with any gain or loss recognized in net income. Adoption of the guidance did not have any effect on our consolidated financial statements.

        On September 28, 2009, we adopted the authoritative guidance on fair value measurement for nonfinancial assets and liabilities, except for items that are recognized or disclosed at fair value in the financial statements on a recurring basis (at least annually). Adoption of the guidance did not have any effect on our consolidated financial statements.

        On September 28, 2009, we adopted the authoritative guidance that revises the factors that should be considered in developing renewal or extension assumptions used to determine the useful life of a recognized intangible asset under the guidance. Adoption of the guidance did not have a material effect on our consolidated financial statements.

        Recently Issued Accounting Guidance Not Yet Adopted.    In June 2009, the Financial Accounting Standards Board ("FASB") issued an accounting standard that requires us to perform an analysis to determine whether our variable interests give us a controlling financial interest in a variable interest entity ("VIE") and should consolidate the VIE. Such analysis requires us to assess whether we have the power to direct the activities of the VIE and if we have the obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE. This guidance eliminates the quantitative approach previously required for determining the primary beneficiary of a VIE and significantly enhances disclosures. The guidance is effective for fiscal years beginning after November 15, 2009. We are currently evaluating the effect the adoption will have on our consolidated financial statements.

        In October 2009, the FASB issued an Accounting Standards Update that provides amendments to the criteria of Accounting Standards Codification Topic 605, "Revenue Recognition", for separately recognizing consideration in multiple-deliverable arrangements. The amendments establish a selling price hierarchy for determining the selling price of a deliverable. This guidance is effective for financial statements issued for fiscal years beginning on or after June 15, 2010. We are currently evaluating the effect the adoption will have on our consolidated financial statements, and we do not expect the adoption will have a material impact on our consolidated financial statements.

        In January 2010, the FASB issued an Accounting Standards Update that amends the disclosure guidance with respect to fair value measurements. Specifically, the new guidance requires disclosure of amounts transferred in and out of Levels 1 and 2 fair value measurements, a reconciliation presented on a gross basis rather than a net basis of activity in Level 3 fair value measurements, greater disaggregation of the assets and liabilities for which fair value measurements are presented, and more robust disclosure of the valuation techniques and inputs used to measure Level 2 and 3 fair value measurements. This guidance is effective for us, with the exception of the new guidance around the Level 3 activity reconciliations. The adoption of the effective portion of the guidance had no impact on

81


Table of Contents

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

2. Basis of Presentation and Preparation (Continued)


our consolidated financial statements. The disclosure requirements for certain Level 3 activities will become effective for fiscal years beginning after December 15, 2010. As we do not currently have any significant Level 3 fair value measurements, we do not expect the adoption will have a material impact on our consolidated financial statements.
