On November 5th 2008, Emcor announced its intent to acquire MOR PPM, Inc. (PPM), a privately held industrial maintenance company. However, Emcor did not initially release the terms of this transaction to investors. As a result of this early lack of transparency, investors sold their equity between November 5th and November 18th largely based on their fear of acquistion value-loss. The price during this period of uncertainty flucuated between $16.77 and $11.22. Finally, on November 21st, Emcor divulged the details of the PPM acquisition to their investors.
