“The results for our fourth quarter reflect the challenging business environment our company, and the world, currently faces,” said Dr. Sehat Sutardja, Marvell Chairman and Chief Executive Officer. “Notwithstanding the challenges we encountered during our fourth quarter, we were able to sustain gross margins, act quickly to lower our operating expenses and generate a healthy free cash flow. However, we believe the current economic climate will not substantially improve over the short term. Consequently, we are taking actions to re-align our business to reflect the realities of the current economic environment. We are focused on improving the operating efficiency of our business and lowering the expenses under our control, while reinforcing the long-term financial strength of Marvell. Our results in our fourth quarter demonstrate initial progress toward these goals.”

Marvell is implementing plans to lower the overall costs and expenses of the company in response to the deteriorating economic environment. As a result of this plan and combined with certain cost reduction measures taken in the fourth quarter of fiscal 2009, Marvell plans to reduce its global workforce by approximately 15 percent, or approximately 850 employees. Marvell estimates that the restructuring charges associated with the reduction in force and consolidation of facilities taken to date will be approximately $20 million, including approximately $14 million related to severance and other employee benefit payments and approximately $6 million related to facility consolidation. Marvell expects the expense reduction actions in the plan to be implemented through calendar year 2009. This estimate includes restructuring charges recorded in the fiscal fourth quarter of 2009 of approximately $9.7 million, comprised of $6.7 million of severance and other employee benefit costs and $3.0 million of facilities consolidation. Marvell estimates that the restructuring measures taken to date will result in approximately $15 million in cash payments in calendar year 2009 and the remainder will be a non-cash accounting-related charge associated with facilities consolidation.

As Marvell implements the remaining portions of this plan, additional charges will be incurred, the amount of which Marvell cannot reasonably estimate at this time, but which will likely include additional severance and other employee benefit related costs, lease termination costs, facility site consolidations or closures, and impaired asset charges.
