Item 1.01 Entry Into A Material Definitive Agreement.

Business Combination Agreement

On May 29, 2026, SPACSphere Acquisition Corp., a Cayman Islands exempted company (“SPACSphere”), entered into a Business Combination Agreement (as it may be amended, supplemented or otherwise modified from time to time, the “Business Combination Agreement”) by and among SPACSphere, SPACSphere Merger Sub Inc., a Delaware corporation and direct wholly owned subsidiary of SPACSphere (“Merger Sub”), and Mobilewalla Holdco, Inc., a Delaware corporation (“Mobilewalla”), pursuant to which Merger Sub will merge with and into Mobilewalla, whereupon the separate corporate existence of Merger Sub will cease and Mobilewalla will be the surviving company and continue in existence as a direct, wholly-owned subsidiary of SPACSphere, on the terms and subject to the conditions set forth therein.

The Business Combination Agreement, and the transactions contemplated thereby to occur at or immediately prior to the Closing (“Transactions”), were approved by the respective boards of directors of SPACSphere and Mobilewalla.

The Domestication

Pursuant to the Business Combination Agreement, prior to the consummation of the Merger (as defined below) (the “Closing”), and subject to the approval of the shareholders of SPACSphere, (i) each then issued and outstanding Class B ordinary share, par value $0.0001 per share, of SPACSphere (a “SPACSphere Class B ordinary share”) outstanding will be converted into one Class A ordinary share, par value $0.0001 per share, of SPACSphere (a “SPACSphere Class A ordinary share”) in accordance with the Articles of Association of SPACSphere (the “Class B conversion”), and, (ii) following the Class B conversion, SPACSphere will domesticate as a Delaware corporation (the “Domestication”) in accordance with Section 388 of the Delaware General Corporation Law and Part XII of the Companies Act (2023 Revision) of the Cayman Islands, as amended.

In connection with the Domestication, (i) each SPACSphere Class A ordinary share outstanding immediately prior to the effective time of the Domestication and following the Class B conversion shall be converted into one share of common stock, par value $0.0001 per share, of SPACSphere (the “New SPACSphere Common Stock”), (ii) each then-issued and outstanding whole warrant exercisable for one SPACSphere Class A ordinary share will be converted into a warrant exercisable for one share of New SPACSphere Common Stock at an exercise price of $11.50 per share on the terms and conditions set forth in the Warrant Agreement, dated as of February 5, 2026, by and between SPACSphere and Odyssey Transfer and Trust Company, as warrant agent (as amended or amended and restated from time to time) (each, a “New SPACSphere Warrant”), and (iii) each then-issued and outstanding right entitling the holder thereof to 1/5 of one SPACSphere Class A ordinary share (each, a “SPACSphere Right”) shall convert automatically into a right to receive 1/5 of one share of New SPACSphere Common Stock at the Closing, pursuant to the Rights Agreement, dated as of February 5, 2026, by and between SPACSphere and Odyssey Transfer and Trust Company, as rights agent. In connection with clauses (i), (ii) and (iii) of this paragraph, each issued and outstanding unit of SPACSphere that has not been previously separated into the underlying SPACSphere Class A ordinary share, SPACSphere warrant and SPACSphere right will be canceled and will entitle the holder thereof to one share of New SPACSphere Common Stock, one-half of one New SPACSphere Warrant, and a right to receive 1/5 of one share of New SPACSphere Common Stock at the Closing.

The Business Combination

The Business Combination Agreement provides for, among other things, the following Transactions: (i) the Domestication, and (ii) the merger of Merger Sub with and into Mobilewalla (the “Merger”), with Mobilewalla being the surviving company of the Merger (Mobilewalla, in its capacity as the surviving company of the Merger, the “Surviving Company”), and as a result of which the Surviving Company will become a wholly-owned subsidiary of SPACSphere. In connection with the Domestication and the consummation of the Business Combination, SPACSphere will change its name to “COVARIATE, INC.” (“New Mobilewalla”) The Domestication, the Merger and the other Transactions contemplated by the Business Combination Agreement are hereinafter referred to as the “Business Combination.”

Among other things, at the effective time of the Merger (the “Effective Time”), (A) the outstanding shares of common stock of Mobilewalla, par value $0.0001 per share (“Mobilewalla Common Stock”) issued and outstanding immediately prior to the Effective Time, and following the conversion or exercise of the outstanding convertible notes, preferred stock, stock options and warrants of Mobilewalla (but excluding any (i) shares of Mobilewalla Common Stock held by Mobilewalla as treasury stock which will be canceled without conversion, and (ii) shares the holders of which perfect rights of appraisal under Delaware law) will be cancelled in exchange for the right to receive a number of shares of New SPACSphere Common Stock (rounded up to the nearest whole share) equal to the quotient obtained by dividing (a) 25,000,000 by (b) the Company Fully Diluted Capital Stock (the “Exchange Ratio”), and (B) each Mobilewalla stock option that is outstanding and unexercised as of immediately prior to the Effective Time will be converted into an option to purchase shares of New SPACSphere Common Stock (“Exchanged Options”) as set forth in the Business Combination Agreement.

“Company Fully Diluted Capital Stock” means, without duplication, the sum of the number of shares of Mobilewalla Common Stock that are (a) issued and outstanding immediately prior to the Effective Time (following the conversion or exercise of the outstanding convertible notes, preferred stock and warrants of Mobilewalla but excluding any treasury stock to be cancelled) and (b) issuable upon exercise of all vested and unvested Mobilewalla options as of immediately prior to the Effective Time but, for the avoidance of doubt, excluding any unissued Mobilewalla options.

Forward-Looking Statements Legend

This Form 8-K contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, that are based on beliefs and assumptions and on information currently available to SPACSphere and Mobilewalla. In some cases, you can identify forward-looking statements by the following words: “may,” “will,” “could,” “would,” “should,” “expect,” “intend,” “plan,” “anticipate,” “believe,” “estimate,” “predict,” “project,” “potential,” “continue,” “ongoing,” “target,” “seek” or the negative or plural of these words, or other similar expressions that are predictions or indicate future events or prospects, although not all forward-looking statements contain these words. Forward-looking statements are predictions, projections and other statements about future events that are based on current expectations and assumptions and, as a result, are subject to risks and uncertainties. Many factors could cause actual future events to differ materially from the forward-looking statements in this document, including but not limited to: (i) the risk that the Business Combination may not be completed in a timely manner or at all, which may adversely affect the price of SPACSphere’s securities; (ii) the risk that the Business Combination may not be completed by SPACSphere’s business combination deadline and the potential failure to obtain an extension of the business combination deadline if sought by SPACSphere; (iii) the failure to satisfy the conditions to the consummation of the Business Combination, including the approval of the Business Combination by the respective shareholders of SPACSphere and Mobilewalla; (iv) the failure to obtain financing to complete the Business Combination and to support the future working capital needs of Mobilewalla and the combined company; (v) the effect of the announcement or pendency of the Business Combination on Mobilewalla’s business relationships, performance, and business generally; (vi) risks that the Business Combination disrupts current plans of Mobilewalla and potential difficulties in the retention of Mobilewalla employees as a result of the Business Combination; (vii) the outcome of any legal proceedings that may be instituted against SPACSphere or Mobilewalla related to the Business Combination Agreement and the Business Combination; (viii) changes to the proposed structure of the Business Combination that may be required or appropriate as a result of applicable laws or regulations or as a condition to obtaining regulatory approval of the Business Combination; (ix) the ability to maintain the listing of SPACSphere’s securities on Nasdaq; (x) the price of SPACSphere’s securities, including volatility resulting from changes in the competitive and highly regulated industries in which Mobilewalla operates, variations in performance across competitors, changes in laws and regulations affecting Mobilewalla’s business and changes in the combined capital structure; (xi) the ability to implement business plans, forecasts, and other expectations after the completion of the Business Combination, and the ability to identify and realize additional opportunities; (xii) the enforceability of Mobilewalla’s intellectual property, and the potential infringement on the intellectual property rights of others, cyber security risks or potential breaches of data security; (xiii) the risk that Mobilewalla may never achieve or sustain profitability; (xiv) changes in the competitive and regulated industries in which Mobilewalla operates, variations in operating performance across competitors, changes in laws and regulations affecting Mobilewalla’s business and changes in the combined capital structure, and (xv) other risks and uncertainties set forth in the section entitled “Risk Factors” and “Special Note Regarding Forward-Looking Statements” in SPACSphere’s Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q and Current Reports on Form 8-K that are available on the website of the SEC at www.sec.gov and other documents filed, or to be filed with the SEC by SPACSphere, including the Registration Statement. The foregoing list of factors is not exhaustive. There may be additional risks that neither SPACSphere nor Mobilewalla presently know or that SPACSphere nor Mobilewalla currently believe are immaterial that could also cause actual results to differ from those contained in the forward-looking statements. You should carefully consider the foregoing factors and the other risks and uncertainties that will be described in the definitive proxy statement to be filed by SPACSphere with the SEC, including those under “Risk Factors” therein, and other documents filed by SPACSphere from time to time with the SEC. These filings identify and address other important risks and uncertainties that could cause actual events and results to differ materially from those contained in the forward-looking statements. Forward-looking statements speak only as of the date they are made. Readers are cautioned not to put undue reliance on forward-looking statements, and SPACSphere and Mobilewalla assume no obligation and, except as required by law, do not intend to update or revise these forward-looking statements, whether as a result of new information, future events, or otherwise. Neither SPACSphere nor Mobilewalla gives any assurance that either SPACSphere or Mobilewalla will achieve its expectations.
