On the Closing Date, at the Effective Time, each share of Spartan Common Stock outstanding as of immediately prior to the Effective Time, was cancelled and automatically converted into the right to receive one Allego Ordinary Share. Effective as of the Effective Time, 54,092,418 shares of Spartan Common Stock issued and outstanding immediately prior to the Effective Time with respect to which stockholders of Spartan validly exercised their redemption rights were redeemed at the Effective Time (the “Redemption Shares”) and were converted into the right to receive from Spartan, in cash, a pro rata portion of the funds in Spartan’s trust account (the “Trust Account”). As a result, approximately $540,984,673 was removed from the Trust Account to pay such stockholders for the Redemption Shares. As of the Effective Time, all Redemption Shares ceased to be outstanding and were automatically cancelled and retired and each holder of a Redemption Share ceased to have any rights with respect thereto, except the right to receive the cash payment in respect thereof from Spartan referred to in the immediately preceding sentence.

On the Closing Date, at the Effective Time, each Spartan Warrant that was outstanding immediately prior to the Effective Time was, pursuant to and in accordance with the Warrant Agreement and the Warrant Assumption Agreement, automatically and irrevocably modified to provide that such Spartan Warrant will no longer entitle the holder thereof to purchase the amount of share(s) of Spartan Class A Common Stock set forth therein and in substitution thereof such warrant will entitle the holder thereof to acquire the same number of Allego Ordinary Shares on the same terms and conditions (including exercisability terms) as were applicable to the Spartan Warrant immediately prior to the Effective Time, except to the extent such terms or conditions were rendered inoperative upon consummation of the Merger.

The description of the Merger set forth above does not purport to be complete and is qualified in its entirety by reference to the Business Combination Agreement, which was filed by Spartan as Exhibit 2.1 to Spartan’s Current Report on Form 8-K filed on July 28, 2021.
