Spartan Acquisition Corp. III, a Delaware corporation (the “Company”), was formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination, with one or more businesses (a “Business Combination”). ~~Agreement~~The amended and restated certificate of incorporation of the Company (the “Organizational Documents”) provides that, prior to the consummation of the initial Business Combination, the Company must provide all holders of shares of Class A common stock, par value $0.0001 per share, included as part of the units sold in the Company’s initial public offering (the “Offering Shares”) with the opportunity to have their Offering Shares redeemed upon the consummation of the initial Business Combination pursuant to, and subject to the limitations of, the Organizational Documents for cash equal to the applicable redemption price per share determined in accordance with the Organizational Documents; provided, however, that the Company may not redeem or repurchase Offering Shares to the extent that such redemption would result in the Company’s failure to have net tangible assets (as determined in accordance with Rule 3a51-1(g)(1) under the Securities Exchange Act of 1934, as amended) in excess of $5 million or any greater net tangible asset or cash requirement which may be contained in the agreement relating to the initial Business Combination.

The Company intends to file an amendment to its Quarterly Report on Form 10-Q for the quarterly period ended September 30, 2021 reflecting this reclassification (“Amended Third Quarter 10-Q”). The adjustments to the Financial Statements will be set forth through expanded disclosure in the financial statements included in the Amended Third Quarter 10-Q.

(i) In the event that the holders of more than 15% of the outstanding shares of Spartan’s Class A Common Stock, par value $0.0001 per share (“Spartan Class A Common Stock”), validly exercised their redemption rights (the “Redemption Rights”) under Spartan’s Amended and Restated Certificate of Incorporation dated February 8, 2021 (the “Spartan Charter”) with respect to such shares, Allego shall issue to E8 Investor certain shares in the capital of Allego, with a nominal value of one euro (EUR 1.00) each (“Allego Common Shares”), valued at $10.00 per Allego Common Share, pursuant to and, in the number determined in accordance with, the terms of the Business Combination Agreement (any such issuance, the “E8 Part A Share Issuance”);

(ii) Allego may issue to E8 Investor, upon E8 Investor’s election, Allego Common Shares for nominal consideration, such that, after giving effect to such issuance (any such issuance, the “E8 Part B Share Issuance” and together with the E8 Part A Share Issuance, the “E8 Share Issuance”) and the consummation of the E8 Part A Share Issuance, if applicable, the Share Contribution, the Private Placement and the Spartan Merger (each as defined below), such Allego Common Shares would not represent more than 15% of the then-outstanding shares in the capital of NewCo, with a nominal value of twelve euro cents (EUR 0.12) each (“NewCo Ordinary Shares”);

(iii) immediately following the E8 Share Issuance (if necessary), Madeleine Charging and, in the event the E8 Part A Issuance or E8 Part B Issuance occurs, E8 Investor, will contribute to NewCo all of the issued and outstanding Allego Common Shares held by it, in exchange for a number of NewCo Ordinary Shares equal to the quotient determined by dividing (i) the Company Valuation (as defined in the Business Combination Agreement) by (ii) $10.00 (the “Share Contribution”), which NewCo Ordinary Shares will be issued to E8 and Madeleine Charging in proportion to the relative number of Allego Common Shares so contributed by each;

(iv) each share of Spartan’s Class B Common Stock, par value $0.0001 per share (“Spartan Founders Stock” and together with Spartan Class A Common Stock, “Spartan Common Stock”) will convert into one share of Spartan Class A Common Stock on a one-for-one basis;

(v) Spartan investors will obtain ownership interests in NewCo through a reverse triangular merger, whereby at the effective time thereof (the “Effective Time”), Merger Sub, a wholly owned subsidiary of NewCo, will merge with and into Spartan, with Spartan surviving the merger as a wholly owned subsidiary of NewCo (the “Surviving Corporation” and such merger, the “Spartan Merger”); and

(vi) Subscribers (as defined below) will subscribe for NewCo Ordinary Shares in the Private Placement (as defined below).

At the Effective Time, as a result of the Spartan Merger:

(i) all shares of Spartan Common Stock held in the treasury of Spartan will be automatically cancelled for no consideration;

(ii) each share of Spartan Common Stock issued and outstanding immediately prior to the Effective Time (other than Redemption Shares (as defined below)) will be cancelled, converted into and exchanged for one validly issued, fully paid and non-assessable NewCo Ordinary Share (the “Per Share Merger Consideration”);

(iii) each share of common stock of Merger Sub, par value $0.0001 per share, issued and outstanding immediately prior to the Effective Time will be converted into and exchanged for one validly issued, fully paid and non-assessable share of common stock of the Surviving Corporation;

(iv) NewCo will assume that certain warrant agreement dated February 8, 2021 by and between Spartan and Continental Stock Transfer & Trust Company, and enter into such amendments thereto as may be necessary such that each of the Spartan warrants governed thereby and then outstanding and unexercised (a “Spartan Warrant”) will automatically be converted into a warrant to acquire one NewCo Ordinary Share (each resulting warrant, an “Assumed Warrant”), which Assumed Warrants will be subject to the same terms and conditions (including exercisability terms) as were applicable to the corresponding Spartan Warrant immediately prior to the Effective Time; and

(v) each Share of Spartan Class A Common Stock issued and outstanding immediately prior to the Effective Time with respect to which a Spartan stockholder has validly exercised its Redemption Rights (such shares, collectively, the “Redemption Shares”) will not be converted into and become a share of the Surviving Corporation, and will not entitle the holder to receive the Per Share Merger Consideration, and, at the Effective Time, will instead be converted into the right to receive a cash amount from the Surviving Corporation calculated in accordance with such Spartan stockholder’s Redemption Rights.

Immediately following the Spartan Merger, NewCo will be converted into a Dutch public limited liability company and its articles of association will be amended.

Representations, Warranties and Covenants; Indemnification

(i) the Spartan Merger has not been consummated by February 23, 2022 (the “Outside Date”), subject to certain exceptions;

(ii) if any governmental entity has issued a final and non-appealable order prohibiting the consummation of the Spartan Merger;

(iii) in the event of a breach by Spartan or Allego, as the case may be, of any of its representations, warranties or other agreements under the Business Combination Agreement that (a) would give rise to the failure of a closing condition in the Business Combination Agreement, if it was continuing on the date of the Closing, and (b) to the extent such breach is curable, has not been cured within 30 days after notice of such breach is provided by the breaching party to the non-breaching party, provided that such right is not available to a party then in breach; or

If the Business Combination Agreement is terminated, it will become void, and there will be no liability under the Business Combination Agreement on the part of any party thereto, except in the case of a willful material breach of the Business Combination Agreement by a party thereto prior to such termination or as otherwise provided under the Business Combination Agreement.

A copy of the Business Combination Agreement is filed with this Current Report on Form 8-K as Exhibit 2.1 and is incorporated herein by reference. The foregoing description of the Business Combination Agreement and the Transactions does not purport to be complete and is qualified in its entirety by reference to the full text of the Business Combination Agreement filed with this Current Report on Form 8-K. The Business Combination Agreement is included to provide security holders with information regarding its terms. It is not intended to provide any other factual information about Spartan, Allego, Madeleine Charging, NewCo, Merger Sub or E8 Investor. In particular, the assertions embodied in representations and warranties by Spartan, Allego, Madeleine Charging, NewCo and Merger Sub contained in the Business Combination Agreement are subject to important qualifications and limitations agreed to by the parties in connection with negotiating such agreement, including being qualified by confidential information in the disclosure schedules provided by the parties in connection with the execution of the Business Combination Agreement, and are subject to standards of materiality applicable to the contracting parties that may differ from those applicable to security holders. The confidential disclosures contain information that modifies, qualifies and creates exceptions to the representations and warranties set forth in the Business Combination Agreement. Moreover, certain representations and warranties in the Business Combination Agreement were used for the purpose of allocating risk between the parties, rather than establishing matters as facts. Accordingly, security holders should not rely on the representations and warranties in the Business Combination Agreement as characterizations of the actual state of facts about Spartan, Allego, Madeleine Charging, NewCo and Merger Sub. Moreover, information concerning the subject matter of the representations and warranties may change after the date of the Business Combination Agreement, which subsequent information may or may not be fully reflected in Spartan’s public disclosures.

Amendment to Letter Agreement

In connection with the execution of the Business Combination Agreement, on July 28, 2021, Spartan, Spartan Acquisition Sponsor III LLC (“Sponsor”) and certain of Sponsor’s executive officers and directors (together with Sponsor, collectively, the “Insiders”) entered into an amendment (the “Letter Agreement Amendment”) to that certain Letter Agreement (the “Existing Letter Agreement”) dated as of February 8, 2021, by and among Spartan, Sponsor and the Insiders party thereto, pursuant to which each Insider has agreed, effective as of the Closing and subject to certain exceptions, to modify the lock-up restrictions set forth in the Existing Letter Agreement such that such Insider will agree not to Transfer (as defined in the Letter Agreement Amendment) any NewCo Ordinary Shares issued to such Insider in respect of any shares of Spartan Class A Common Stock that may be received by such Insider at the Closing upon conversion of the Spartan Founders Stock pursuant to the Business Combination Agreement until (i) six months after the Closing or (ii) earlier if (a) the last reported sale price of NewCo Ordinary Shares equals or exceeds $12.00 per share for any 20 trading days within a 30-day trading period commencing at least 120 days after the date upon which the Closing occurs (the “Closing Date”), (b) NewCo consummates a subsequent liquidation, merger, stock exchange or other similar transaction which results in all NewCo’s stockholders having the right to exchange their shares of NewCo Ordinary Shares for cash, securities, or other property or (c) the board of directors of NewCo determines that the earlier termination of such restrictions is appropriate. Under the Letter Agreement Amendment, each Insider also agreed, effective as of the Closing and subject to certain exceptions, to modified transfer restrictions prohibiting the Transfer of any Assumed Warrants, and any NewCo Ordinary Shares underlying any Assumed Warrants, until 30 days after the Closing Date.

The foregoing description of the Letter Agreement Amendment is qualified in its entirety by reference to the full text of the Letter Agreement Amendment, a copy of which is filed as Exhibit 10.1 to this Current Report on Form 8-K, and incorporated herein by reference.

(ii) E8 Investor will agree, subject to certain exceptions, not to Transfer (as defined in the Registration Rights Agreement) securities received by it in the E8 Part B Share Issuance until the date that is 18 months after the Closing or earlier if, subsequent to the Closing, NewCo consummates a liquidation, merger, stock exchange or other similar transaction which results in all of NewCo’s stockholders having the right to exchange their NewCo Ordinary Shares for cash, securities or other property.

Subscription Agreements

In connection with the execution of the Business Combination Agreement, on July 28, 2021, Spartan and NewCo entered into separate subscription agreements (collectively, the “Subscription Agreements”) with a number of investors (collectively, the “Subscribers”), pursuant to which the Subscribers agreed to purchase an aggregate of 15,000,000 NewCo Ordinary Shares (the “PIPE Shares”), for a purchase price of $10.00 per share and an aggregate purchase price of $150,000,000, in a private placement (the “Private Placement”).

Forward-Looking Statements

This Current Report on Form 8-K includes “forward-looking statements.” All statements, other than statements of present or historical fact included in this Current Report on Form 8-K, regarding Spartan’s proposed business combination with Allego, the ability to consummate the transaction, the benefits of the transaction, Spartan’s and Allego’s future financial performance following the transaction, as well as Spartan’s and Allego’s strategy, future operations, financial position, estimated revenues, and losses, projected costs, prospects, plans and objectives of management are forward-looking statements. When used in this Form 8-K, the words “could,” “should,” “will,” “may,” “believe,” “anticipate,” “intend,” “estimate,” “expect,” “project,” the negative of such terms and other similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain such identifying words. These forward-looking statements are based on management’s current expectations and assumptions about future events and are based on currently available information as to the outcome and timing of future events. Except as otherwise required by applicable law, Spartan and Allego disclaim any duty to update any forward looking statements, all of which are expressly qualified by the statements in this section, to reflect events or circumstances after the date of this Current Report on Form 8-K. Spartan and Allego caution you that these forward-looking statements are subject to numerous risks and uncertainties, most of which are difficult to predict and many of which are beyond the control of either Spartan or Allego. In addition, Spartan cautions you that the forward-looking statements contained in this Current Report on Form 8-K are subject to the following factors: (i) the occurrence of any event, change or other circumstances that could delay the Transactions or give rise to the

termination of the agreements related thereto; (ii) the outcome of any legal proceedings that may be instituted against Spartan or Allego following announcement of the Transactions; (iii) the inability to complete the Transactions due to the failure to obtain approval of the shareholders of Spartan, or other conditions to Closing in the agreements related to the Transactions; (iv) the risk that the Transactions disrupt Spartan’s or Allego’s current plans and operations as a result of the announcement of the Transactions; (v) Allego’s ability to realize the anticipated benefits of the Transactions, which may be affected by, among other things, competition and the ability of Allego to grow and manage growth profitably following the Transactions; (vi) costs related to the Transactions; (vii) changes in applicable laws or regulations; (viii) risks relating to the uncertainty of the projected operating and financial information with respect to Allego; (ix) risks related to Allego’s business and the timing of expected business milestones or results; (x) Allego’s dependence on widespread acceptance and adoption of electric vehicles and increased installation of charging stations; (xi) overall demand for electric vehicle charging and the potential for reduced demand if governmental rebates, tax credits and other financial incentives are reduced, modified or eliminated or governmental mandates to increase the use of electric vehicles or decrease the use of vehicles powered by fossil fuels, either directly or indirectly through mandated limits on carbon emissions, are reduced, modified or eliminated; (xii) risks related to Allego’s dependence on its intellectual property and the risk that Allego’s technology could have undetected defects or errors; (xiii) the effects of the COVID-19 pandemic on Allego’s business or future results; (xiv) the amount of redemption requests made by Spartan’s stockholders; (xv) the ability of Spartan or the combined company to issue equity or equity-linked securities in connection with the Transactions or in the future; (xvi) the occurrence of events that may give rise to a right of one or both of Spartan and Allego to terminate the definitive agreements related to the Transactions; and (xvii) the possibility that Allego may be adversely affected by other economic, business, and/or competitive factors. Should one or more of the risks or uncertainties described in this Current Report on Form 8-K, or should underlying assumptions prove incorrect, actual results and plans could different materially from those expressed in any forward-looking statements. There may be additional risks that neither Spartan nor Allego presently know or that Spartan and Allego currently believe are immaterial that could cause actual results to differ from those contained in the forward-looking statements. Additional information concerning these and other factors that may impact the operations and projections discussed herein can be found in Spartan’s periodic filings with the SEC, including its prospectus filed with the SEC on February 10, 2021 and its Current Reports on Form 8-K, as well as the Registration Statement and the proxy statement/prospectus. Spartan’s SEC filings are available publicly on the SEC’s website at www.sec.gov.
