Introductory Note

As previously announced, on July 28, 2021, Spartan Acquisition Corp. III, a Delaware corporation (“Spartan”), Athena Pubco B.V., a Dutch private limited liability company (besloten vennootschap met beperkte aansprakelijkheid) (“Athena Pubco”), Athena Merger Sub, Inc., a Delaware corporation (“Merger Sub”), Madeleine Charging B.V., a Dutch private limited liability company (besloten vennootschap met beperkte aansprakelijkheid) (“Madeleine Charging”), Allego Holding B.V., a Dutch private limited liability company (besloten vennootschap met beperkte aansprakelijkheid) (“Allego”), and, solely with respect to the sections specified therein, E8 Partenaires, a French societe par actions simplifee (“E8 Investor”), entered into a Business Combination Agreement and Plan of Reorganization (the “Business Combination Agreement”). Subject to the satisfaction or waiver of the conditions to closing (the “Closing”) of the transactions contemplated by the Business Combination Agreement (the “Transactions”), the Transactions will effect a business combination between Spartan and Allego. Capitalized terms used herein but not otherwise defined shall have the meaning ascribed to them in the Business Combination Agreement, a copy of which was filed as Exhibit 2.1 to the Current Report on Form 8-K filed with the SEC by Spartan on July 28, 2021, and is incorporated herein by reference.

On February 28, 2022, Spartan, Athena Pubco, Merger Sub, Madeleine Charging, Allego and, solely for the purposes of the sections specified therein, E8 Investor entered into that certain Amendment to the Business Combination Agreement (the “Amendment”) pursuant to which, among other things, the parties thereto (i) modified the applicable thresholds that determine whether certain fees payable to E8 Investor will be paid in cash, Company Common Shares or a combination of cash and Company Common Shares.

According to the Amendment, in the event the holders of: (a) more than 15% but not more than 72.4% of Spartan Class A Common Stock exercise their Redemption Rights in respect of such shares (the “Part A First Redemption Threshold”), Allego will issue to E8 Investor a number of Company Common Shares equal to 50% of the amounts payable as “Part A of the Fees” (as such term is defined in the E8 Agreement); and (b) more than 72.4% of the outstanding shares of Spartan Class A Common Stock exercise Redemption Rights in respect of such shares (the “Part A Second Redemption Threshold” and, together with the Part A First Redemption Threshold, each a “Part A Redemption Threshold”), Allego will issue to E8 Investor a number of Company Common Shares equal to 100% of the amounts payable as Part A of the Fees, in each case, on the terms and subject to the conditions as more particularly set forth in the E8 Agreement and the Business Combination Agreement.

In addition, for purposes of determining if a Part A Redemption Threshold has been met, any net cash proceeds received by Athena Pubco from the issuance of any NewCo Ordinary Shares in connection with Closing (at a price of $10.00 per NewCo Ordinary Share) in excess of $193.5 million, other than any net cash proceeds from the Trust Account, shall be deemed to reduce, on a dollar for dollar basis, the value of the shares of Spartan Class A Common Stock with respect to which the holders thereof have exercised their Redemption Rights (with the value of one such share being deemed to be worth $10.00), and with each such share being deemed not to have been redeemed.

The foregoing description of the Amendment does not purport to be complete and is qualified in its entirety by the terms and conditions of the Amendment, a copy of which is filed as Exhibit 2.2 to this Current Report on Form 8-K and is incorporated herein by reference.

Forward-Looking Statements

This Current Report on Form 8-K includes “forward-looking statements” within the meaning of the “safe harbor” provisions of the United States Private Securities Litigation Reform Act of 1995. These forward-looking statements are provided for illustrative purposes only and are not intended to serve as, and must not be relied on by any investor as, a guarantee, an assurance, a prediction or a definitive statement of fact or probability. Spartan’s and Allego’s actual results may differ from their expectations, estimates, and projections and, consequently, you should not rely on these forward-looking statements as predictions of future events. Words such as “expect,” “estimate,” “project,” “budget,” “forecast,” “anticipate,” “intend,” “plan,” “may,” “will,” “could,” “should,” “believes,” “predicts,” “potential,” “continue,” and similar expressions (or the negative versions of such words or expressions) are intended to identify such forward-looking statements. These forward-looking statements include, without

2

limitation, Spartan’s and Allego’s expectations with respect to future performance and anticipated financial impacts of the Transactions, the satisfaction or waiver of the closing conditions to the Transactions, and the timing of the completion of the Transactions. These forward-looking statements involve significant risks and uncertainties that could cause the actual results to differ materially, and potentially adversely, from those expressed or implied in the forward-looking statements. Most of these factors are outside Spartan’s and Allego’s control and are difficult to predict. Factors that may cause such differences include, but are not limited to: (i) the occurrence of any event, change, or other circumstances that could give rise to the termination of the Business Combination Agreement or could otherwise cause the Transactions to fail to close; (ii) the outcome of any legal proceedings that may be instituted against Spartan, Athena Pubco and/or Allego following the announcement of the Transactions; (iii) the inability to complete the Transactions, including due to failure to obtain approval of the stockholders of Spartan, certain regulatory approvals, or the satisfaction of other conditions to closing in the Business Combination Agreement; (iv) the impact of the COVID-19 pandemic on Allego’s business and/or the ability of the parties to complete the Transactions; (v) the inability to obtain or maintain the listing of Athena Pubco’s common shares on the New York Stock Exchange following the Transactions; (vi) the risk that the Transactions disrupt current plans and operations as a result of the announcement and consummation of the Transactions; (vii) the ability to recognize the anticipated benefits of the Transactions, which may be affected by, among other things, competition, the ability of Allego to grow and manage growth profitably, and to retain its key employees; (viii) costs related to the Transactions; (ix) changes in applicable laws or regulations; and (x) the possibility that Allego, Spartan or Athena Pubco may be adversely affected by other economic, business, and/or competitive factors. The foregoing list of factors is not exclusive. Additional information concerning certain of these and other risk factors is contained in Spartan’s most recent filings with the SEC and in the registration statement on Form F-4 (the “Form F-4”), including the proxy statement/prospectus forming a part thereof filed by Athena Pubco in connection with the Transactions on September 30, 2021, as amended on December 14, 2021, January 18, 2022 and February 1, 2022. All subsequent written and oral forward-looking statements concerning Spartan, Allego or Athena Pubco, the transactions described herein or other matters and attributable to Spartan, Allego, Athena Pubco or any person acting on their behalf are expressly qualified in their entirety by the cautionary statements above. Readers are cautioned not to place undue reliance upon any forward-looking statements, which speak only as of the date made. Each of Spartan, Allego and Athena Pubco expressly disclaims any obligations or undertaking to release publicly any updates or revisions to any forward-looking statements contained herein to reflect any change in their expectations with respect thereto or any change in events, conditions, or circumstances on which any statement is based, except as required by law.
