Business Combinations and Acquisitions As described in Note 1- Description of Business, the Business Combination was consummated on February 10, 2020. For financial accounting and reporting purposes under U.S. GAAP, the Business Combination was accounted for as a reverse acquisition and recapitalization, with no goodwill or other intangible asset recorded. Under this method of accounting, Gores III (legal acquirer) is treated as the acquired entity and Shay (legal acquiree) is deemed to have issued common stock for the net assets and equity of Gores III consisting of mainly cash, accompanied by simultaneous equity recapitalization of Shay (Recapitalization). The net assets of Gores III are stated at historical cost, and accordingly the equity and net assets of Shay have not been adjusted to fair value. Consequently, the consolidated assets, liabilities and results of operations of Shay are the historical financial statements of PAE Incorporated and the Gores III assets, liabilities and results of operations are consolidated with the assets, liabilities and results of operations of Shay beginning on the Closing Date. Shares and earnings per share information prior to the Business Combination have been retroactively restated to reflect the exchange ratio established in the Recapitalization. Other than professional fees paid to consummate the transaction, the Business Combination primarily involved the exchange of cash and equity between Gores III, Shay and the stockholders of the respective companies. The aggregate proceeds paid to the Shay Stockholders on the Closing Date was approximately $424.2 million. The remainder of the consideration paid to the Shay Stockholders consisted of 21,127,823 newly issued shares of Class A Common Stock of PAE Incorporated, par value $0.0001 per share (Class A Common Stock). In addition to the foregoing consideration paid on the Closing Date, former stockholders of Shay are entitled to receive additional Earn-Out Shares from PAE of up to an aggregate of 4,000,000 shares of Class A Common Stock if the price of Class A Common Stock trading on the Nasdaq exceeds certain thresholds during the five-year period following the completion of the Business Combination. See Note 11 - Stockholders Equity - Earn-Out Agreement for additional information. The Company also has certain warrants issued by Gores III that remain outstanding after the Business Combination. See Note 11 - Stockholders Equity - Warrants for further information about the warrants. In connection with the Business Combination, the Company recorded $20.9 million, net of tax as a reduction to additional paid in capital related to the transaction costs. These costs were directly attributable to the Recapitalization. Post-Closing Adjustment During the third quarter, pursuant to the post-closing adjustment provisions contained in the Merger Agreement, the Company made a post-closing adjustment payment of $20.2 million to the Shay Stockholders. Additionally, during the third quarter, the Company paid $1.0 million to certain members of PAE management in connection with the post-closing adjustment and such amount was recorded as compensation expense.
