Item 7.01 Regulation FD Disclosure.

As previously disclosed in the Current Report on Form 8-K filed with the Securities and Exchange Commission (the “SEC”) on April 25, 2022, XPAC Acquisition Corp., an exempted company limited by shares incorporated under the laws of the Cayman Islands (“XPAC”) entered into a Business Combination Agreement on April 25, 2022 with (i) SUPERBAC PubCo Holdings Inc., an exempted company limited by shares incorporated under the laws of the Cayman Islands (“PubCo”), (ii) BAC1 Holdings Inc., an exempted company limited by shares incorporated under the laws of the Cayman Islands and a direct wholly owned subsidiary of PubCo, (iii) BAC2 Holdings Inc., an exempted company limited by shares incorporated under the laws of the Cayman Islands and a direct wholly owned subsidiary of PubCo, and (iv) SuperBac Biotechnology Solutions S.A., a corporation incorporated under the laws of Brazil (“SuperBac”) (the transactions contemplated thereby, the “Business Combination”).

Attached as Exhibit 99.1 to this Current Report on Form 8-K is an investor presentation dated July 2022 that XPAC and SuperBac have prepared in connection with the proposed Business Combination.

The information in this Item 7.01, including Exhibit 99.1, is furnished and shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to liabilities under that section, and shall not be deemed to be incorporated by reference into the filing of XPAC under Securities Act of 1933, as amended, or under the Exchange Act, regardless of any general incorporation language in such filings.

Additional Information about the Proposed Business Combination and Where to Find It

The proposed Business Combination will be submitted to the shareholders of XPAC for their consideration. On July 11, 2022, PubCo filed a registration statement on Form F-4 (the “Registration Statement”) with the SEC. The Registration Statement includes a preliminary proxy statement to be distributed to XPAC’s shareholders in connection with XPAC’s solicitation for proxies for the vote by XPAC’s shareholders in connection with the proposed Business Combination and other matters as described in the Registration Statement, and a preliminary prospectus relating to the offer of the securities to be issued in connection with the completion of the proposed Business Combination. After the Registration Statement has been declared effective, XPAC will mail a definitive proxy statement/prospectus and other relevant documents to its shareholders as of the record date established for voting on the proposed Business Combination. XPAC’s shareholders and other interested persons are advised to read the preliminary proxy statement/prospectus and any amendments thereto and, once available, the definitive proxy statement/prospectus, and documents incorporated by reference therein filed in connection with XPAC’s solicitation of proxies for its special meeting of shareholders to be held to approve, among other things, the proposed Business Combination, because these documents do and will contain important information about XPAC, SuperBac and PubCo and the proposed Business Combination. Shareholders may also obtain a copy of the preliminary proxy statement/prospectus and, once available, the definitive proxy statement/prospectus, as well as other documents filed with the SEC regarding the proposed Business Combination and other documents filed with the SEC by XPAC, without charge, at the SEC’s website located at www.sec.gov or by written request sent to 55 West 46th Street, 30th Floor, New York, NY 10036.

INVESTMENT IN ANY SECURITIES DESCRIBED HEREIN HAS NOT BEEN APPROVED OR DISAPPROVED BY THE SEC OR ANY OTHER REGULATORY AUTHORITY NOR HAS ANY AUTHORITY PASSED UPON OR ENDORSED THE MERITS OF THE OFFERING OR THE ACCURACY OR ADEQUACY OF THE INFORMATION CONTAINED HEREIN. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

Participants in the Solicitation

XPAC, SuperBac, PubCo and certain of their respective directors, executive officers and other members of management, employees and consultants may, under SEC rules, be deemed to be participants in the solicitations of proxies from XPAC’s shareholders in connection with the proposed Business Combination. Information regarding the persons who may, under SEC rules, be deemed participants in the solicitation of XPAC’s shareholders in connection with the proposed Business Combination are set forth in the preliminary proxy statement/prospectus which forms part of the Registration Statement. You can find more information about XPAC’s directors and executive officers and their respective interests in XPAC in XPAC’s final prospectus that forms a part of XPAC’s Registration Statement on Form S-1 (Reg No. 333-256097), filed with the SEC pursuant to Rule 424(b)(4) on August 2, 2021 (the “Prospectus”). Additional information regarding the participants in the proxy solicitation and a description of their direct and indirect interests are included in the preliminary proxy statement/prospectus which forms part of the Registration Statement. Shareholders, potential investors and other interested persons should read the definitive proxy statement/prospectus carefully when it becomes available before making any voting or investment decisions. You may obtain free copies of these documents from the sources indicated above.

No Offer or Solicitation

This communication does not constitute an offer to sell or the solicitation of an offer to buy any securities, or a solicitation of any vote or approval, nor shall there be any sale of securities in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such jurisdiction.

This communication relates to a potential financing through a private placement of common stock of a newly formed holding company to be issued in connection with the transaction. This communication shall not constitute a “solicitation” as defined in Section 14 of the Securities Exchange Act of 1934, as amended. No offering of securities shall be made except by means of a prospectus meeting the requirements of Section 10 of the Securities Act, as amended, or an applicable exemption from the registration requirements thereof.

Forward-Looking Statements

The information in this communication includes “forward-looking statements” within the meaning of the “safe harbor” provisions of the United States Private Securities Litigation Reform Act of 1995.

Forward-looking statements may be identified by the use of words such as “estimate,” “plan,” “project,” “forecast,” “intend,” “will,” “expect,” “anticipate,” “believe,” “seek,” “target”, “may”, “predict”, “should”, “would”, “potential”, “seem”, “future”, “outlook” or other similar expressions (or negative versions of such words or expressions) that predict or indicate future events or trends or that are not statements of historical matters. These forward-looking statements include, but are not limited to, statements regarding XPAC’s, SuperBac’s, and PubCo’s estimates and forecasts of financial and performance metrics, projections of market opportunity and market share, expectations and timing related to product development, commercialization, commercial models, business growth and expansion, as well as discussion of SuperBac’s business plan in general, potential benefits of the transaction, potential financings to be obtained by SuperBac in the ordinary course of business or any equity or debt financings to be obtained in connection with the Business Combination and the satisfaction of conditions to closing of the Business Combination, including the Minimum Cash Condition. These statements are based on various assumptions, whether or not identified in this communication, and on the current expectations of XPAC’s, SuperBac’s and PubCo’s management and are not predictions of actual performance. 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. Actual events and circumstances are difficult or impossible to predict and will differ from assumptions, and such differences may be material. Many actual events and circumstances are beyond the control of XPAC, SuperBac and PubCo.

These forward-looking statements are subject to a number of risks and uncertainties, including those factors discussed in the Prospectus, and XPAC’s Annual Report on Form 10-K for the fiscal year ended December 31, 2021, which was filed with the SEC on March 30, 2021, in each case, under the heading “Risk Factors,” and other documents that XPAC has filed, or will file, with the SEC. If any of these risks materialize or our assumptions prove incorrect, actual results could differ materially from the results implied by these forward-looking statements. There may be additional risks that XPAC, SuperBac and PubCo do not presently know or that XPAC, SuperBac, and PubCo do not currently believe are immaterial that could also cause actual results to differ from those contained in the forward-looking statements. In addition, forward-looking statements reflect XPAC’s, SuperBac’s, and PubCo’s expectations, plans or forecasts of future events and views as of the date of this communication. XPAC, SuperBac, and PubCo anticipate that subsequent events and developments will cause XPAC’s, SuperBac’s, and PubCo’s assessments to change. However, while XPAC, SuperBac and PubCo may elect to update these forward-looking statements at some point in the future, XPAC, SuperBac and PubCo specifically disclaim any obligation to do so. These forward-looking statements should not be relied upon as representing XPAC’s, SuperBac’s or PubCo’s assessments as of any date subsequent to the date of this communication. Accordingly, undue reliance should not be placed upon the forward-looking statements.
