Three agreements for US public company acquisitions with a deal value of $100 million or more were filed this past week.

On September 2, 2014, Thoma Bravo, LLC agreed to acquire technology performance company Compuware Corporation in an all-cash transaction valued at $2.5 billion. The acquisition represents the culmination of shareholder activist Elliott Management’s efforts to extract value from its investment in Compuware. In connection with the merger agreement, Thoma Bravo entered into a voting agreement with Elliott Management, which owns 9.5% of Compuware's outstanding stock and had previously made an offer to acquire Compuware. Thoma Bravo will also enter into voting agreements with those Compuware directors and officers who are affiliated with Elliott Management, who collectively own an additional 3.5% of Compuware stock.

Last year, under pressure from Elliott Management, Compuware partially spun out its subsidiary Covisint Corporation in an IPO. Under the merger agreement, Compuware is required to complete the spin-off of Covisint within 60 days after the signing date, unless Compuware enters into a definitive agreement to sell Covisint before the end of that 60-day period. If Compuware enters into such an agreement, the parties have agreed to amend the merger agreement to provide for a mechanism for transferring the consideration received in that sale to Compuware's shareholders. The closing of the merger is therefore conditioned on either (i) the closing of the spin-off of Covisint or (ii) Compuware's entry into a definitive agreement to sell Covisint.
