InItem accordance with Financial Accounting Standards Board Accounting Standards Codification 480, “Distinguishing Liabilities from Equity” (“ASC 480”), redemption provisions not solely within the control of the Company require common stock subject to redemption to be classified outside of permanent equity1. ~~In the Company’s (i) audited balance sheet as of February 11, 2021, included in the Company’s Current Report on Form 8-K filed with the U~~01.S. ~~Securities~~Entry ~~and~~into Exchange Commission (the “SEC”) on February 17, 2021, as previously revised in the Company’s Form 10-Q for the quarterly period ended March 31, 2021, filed with the SEC on June 3, 2021; (ii) unaudited interim financial statements included in the Company’s Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2021, filed with the SEC on June 3, 2021 and (iii) unaudited interim financial statements included in the Company’s Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2021, filed with the SEC on August 3, 2021 (collectively, the “Financial Statements”), the Company classified a ~~portion~~Material ofDefinitive ~~its Class A common stock in permanent equity, or total stockholders’ (deficit) equity~~Agreement. Although the Company did not specify a maximum redemption threshold, the Organizational Documents provision described above does not permit the Company to redeem the Offering Shares in an amount that would cause its net tangible assets to be less than $5,000,001. Management has now determined, after consultation with its advisors, and in light of SEC comments recently reported in respect of other special purpose acquisition companies, that the Offering Shares can be redeemed or become redeemable subject to the occurrence of future events considered to be outside the Company’s control. Accordingly, the Company’s management has concluded that the Company should present all redeemable shares of Class A common stock as temporary equity, resulting in the adjustment to the initial carrying value of the shares of Class A common stock subject to redemption with the offset recorded to additional paid-in capital (to the extent available), accumulated deficit and Class A common stock in accordance with ASC 480. In connection with the change in presentation for the Class A common stock subject to possible redemption, the Company revised its earnings per share calculation to allocate income and losses shared pro rata between the two classes of shares.

On ~~November~~February 2328, ~~2021~~2022, ~~the~~Spartan, ~~Audit~~Athena ~~Committee~~Pubco, ofMerger ~~the~~Sub, ~~board~~Madeleine ofCharging, ~~directors~~Allego ~~of the Company concluded~~and, ~~after~~solely ~~discussion~~for ~~with~~ the ~~Company’s~~purposes ~~management,~~of ~~that~~ the ~~Financial~~sections ~~Statements~~specified ~~should~~therein, noE8 ~~longer~~Investor beentered ~~relied~~into ~~upon~~that ~~due~~certain toAmendment ~~changes required~~ to ~~reclassify all of~~ the ~~Company’s~~Business ~~Class A~~Combination ~~common~~Agreement ~~stock~~(the ~~subject~~“Amendment”) topursuant ~~possible redemption in temporary equity.

~~The~~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 ~~has~~Common ~~discussed~~Shares equal to 50% of the ~~matters~~amounts ~~disclosed~~payable as “Part A of the Fees” (as such term is defined in ~~this~~the ~~Current~~E8 ~~Report~~Agreement); onand ~~Form~~(b) ~~8-K~~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 ~~its~~the ~~independent~~Part ~~registered~~A ~~public~~First ~~accounting~~Redemption ~~firm~~Threshold, ~~WithumSmith+Brown~~each a “Part A Redemption Threshold”), PCAllego 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.

1In 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.

~~Dated:~~This ~~November~~Current 23Report 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, ~~2021~~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

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.

Important Information and Where to Find It

Spartan, Allego and Athena Pubco urge investors, stockholders and other interested persons to read the Form F-4, including the proxy statement/prospectus incorporated by reference therein, as well as other documents filed with the SEC in connection with the Transactions, as these materials contain important information about Allego, Spartan, and the Transactions. Such persons can also read Spartan’s final prospectus dated February 8, 2021 (SEC File No. 333-252866), for a description of the security holdings of Spartan’s officers and directors and their respective interests as security holders in the consummation of the Transactions. The definitive proxy statement/prospectus has been mailed to Spartan’s stockholders as of January 18, 2021. Stockholders will also be able to obtain copies of such documents, without charge, once available, at the SEC’s website at www.sec.gov, or by directing a request to: Spartan Acquisition Corp. III, 9 West 57th Street, 43rd Floor, New York, NY 10019, or (212) 515-3200.

Information concerning the interests of Spartan’s, Athena Pubco’s and Allego’s participants in the solicitation, which may, in some cases, be different than those of Spartan’s, Athena Pubco’s and Allego’s equity holders generally, is set forth in the proxy statement/prospectus relating to the Transactions.
