Item 1.01 Entry into a Material Definitive Agreement.

On November 17, 2025, Wintergreen Acquisition Corp. (the “Company” or “SPAC”), a Cayman Islands exempted company, entered into a Merger Agreement (the “Merger Agreement”) with Wintergreen Acquisition Merger Subsidiary Corp., a Cayman Islands exempted company and wholly-owned subsidiary of the Company (“Merger Sub”), and KIKA Technology INC., a Cayman Islands exempted company (“KIKA”).

Pursuant to the Merger Agreement and in accordance with the Companies Act (as revised) of the Cayman Islands, Merger Sub will merge with and into KIKA, with KIKA surviving the merger as a wholly-owned subsidiary of the Company (the “Merger”). Simultaneously with the closing of the Merger (the “Closing”), the Company will change its name to “KIKA Inc.” or such other name as determined by KIKA, subject to approval by the Registrar of Companies in the Cayman Islands.

The Merger is intended to qualify as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended, and the Merger Agreement is intended to constitute a plan of reorganization thereunder.

The date of the Closing is expected to occur in the first half of 2026, or promptly following the satisfaction or waiver of the conditions to closing set forth in the Merger Agreement, including the approval of the Merger Agreement and the transactions contemplated thereby by the shareholders of the Company and KIKA, and the declaration of effectiveness by the SEC of a proxy/registration statement on Form S-4 to be jointly filed by parties in connection with the Company’s shareholder meeting and issuance of the Consideration Shares (defined below).

Merger Consideration

In connection with the Merger, the shareholders of KIKA (the “KIKA Shareholders”) will receive ordinary shares of the Company (the “Consideration Shares”) in an amount equal to the Valuation of KIKA (as defined in the Merger Agreement) divided by the SPAC Per Share Redemption Price (as defined in the Merger Agreement), rounded up to the nearest whole share. The Consideration Shares will be allocated among the KIKA Shareholders in accordance with the Allocation Statement (as defined in the Merger Agreement).

Representations and Warranties

The parties to the Merger Agreement made representations and warranties customary for transactions of this type. The representations and warranties of KIKA are qualified in certain respects by materiality or a Company Material Adverse Effect, which is defined to exclude certain events such as general economic conditions, industry-wide impacts, changes in financial markets, acts of war or terrorism, actions permitted by the Merger Agreement, changes in laws or accounting rules, the announcement of the transactions, natural disasters, or failures to meet projections (subject to underlying causes).

Covenants

The Merger Agreement contains covenants customary for transactions of this type, including obligations for the parties to operate their respective businesses in the ordinary course prior to the Closing and to refrain from taking certain specified actions without the consent of the other party. The parties have also agreed to use commercially reasonable efforts to consummate the transactions, including obtaining necessary approvals and cooperating in the preparation of the registration statement on Form S-4 (or other applicable form) and proxy statement required in connection with the Merger. Additional covenants include provisions for the Company to provide public shareholders with redemption rights in accordance with its organizational documents and IPO trust agreement.

Conditions to Closing

The consummation of the Merger is subject to conditions customary for transactions of this type, including, among others: (i) receipt of the requisite approvals from the shareholders of the Company and KIKA and entry by KIKA shareholders of a Lock Up Agreement described in further detail below; (ii) the effectiveness of the registration statement on Form S-4; (iii) receipt of any required governmental approvals; (iv) the absence of any order, law, or regulation enjoining or prohibiting the Merger; (v) the Company having at least $5,000,001 in net tangible assets immediately after the Closing; (vi) compliance with covenants and the accuracy of representations and warranties (subject to materiality qualifications); and (vii) the absence of a material adverse effect on either party.

Termination Provisions

The Merger Agreement may be terminated at any time prior to the Closing under circumstances customary for transactions of this type, including: (i) by mutual written consent of the parties; (ii) by either party if the Merger is not consummated by the Outside Closing Date, provided the terminating party is not in breach; (iii) by either party if a governmental authority issues a final, non-appealable order enjoining the Merger; (iv) by the Company if KIKA is in material breach of its representations, warranties, or covenants; (v) by KIKA if the Company is in material breach; or (vi) by either party if the requisite shareholder approvals are not obtained. There are no termination fees, but the parties remain liable for willful breaches or fraud.

Related Agreements

Concurrently with the execution of the Merger Agreement, the Company, KIKA, and the KIKA Shareholders entered into the following agreements:

Company Transaction Support Agreement, pursuant to which the KIKA Shareholders agreed to vote in favor of the Merger and provide the requisite shareholder approval in accordance with KIKA’s organizational documents and the Cayman Companies Act.

In connection with the Closing, the Company, KIKA, and each KIKA Shareholder will enter into non-compete and non-solicitation agreements and lock up agreements.

Lock Up Agreement provides for a six-month lock-up period post-closing during which Company Shareholders are restricted from transferring, selling, or encumbering Consideration Shares, with exceptions for customary permitted transferees.

Non-Compete and Non-Solicitation Agreement establishes a two-year restricted period post-closing prohibiting the Company Shareholders from engaging in competing businesses within the Company Group's operating jurisdictions (Cayman Islands, British Virgin Islands, and Hong Kong) or serving in roles for competitors.

The foregoing description of the Merger Agreement does not purport to be complete and is qualified in its entirety by the terms and conditions of the Merger Agreement, a copy of which is attached as Exhibit 2.1 hereto, and the terms of which are incorporated herein by reference.
