On August 11, 2026, Payoneer Global Inc., a Delaware corporation (the “Company” or “Payoneer”), filed its definitive proxy statement on Schedule 14A (as such may be supplemented from time to time, the “Proxy Statement”) with the Securities and Exchange Commission (the “SEC”) with respect to the special meeting of Payoneer’s stockholders (the “Special Meeting”) to be held in connection with the transactions contemplated by that certain Agreement and Plan of Merger (the “Merger Agreement”), dated as of June 12, 2026, by and among the Company, Neon Maple Parent Inc., a corporation incorporated pursuant to the laws of Canada (“Nuvei Parent”), and Panda Acquisition Sub Inc., a Delaware corporation and wholly owned indirect subsidiary of Nuvei Parent (“Merger Sub”), pursuant to which Merger Sub will merge with and into the Company (the “Merger”), with the Company surviving as a wholly owned subsidiary of Nuvei Parent.

The Special Meeting is scheduled for September 14, 2026, beginning at 9:00 a.m. Eastern Time. Payoneer’s stockholders of record as of the close of business on August 6, 2026 will be eligible to vote at the Special Meeting. The information contained in this Current Report on Form 8-K (this “Form 8-K”) should be read in conjunction with the Proxy Statement, which should be read in its entirety.

Litigation Relating to the Merger

As of the date of this Form 8-K, two lawsuits relating to the Merger (the “Lawsuits”) have been filed: (i) Kevin Turner v. Payoneer Global Inc., et al. Index No. 654853/2026, which was filed on August 20, 2026; and (ii) John Clark vs. Payoneer Global Inc., et al. Index No. 654863/2026, which was filed on August 21, 2026, both of which were filed in the Supreme Court of the State of New York, County of New York. The Lawsuits were filed by purported stockholders of the Company as individual actions and allege that the Proxy Statement was materially incomplete due to certain misrepresentations and omissions in violation of New York common law. The Lawsuits name as defendants the Company’s directors and the Company and seek, among other relief, an order enjoining the consummation of the Merger. There can be no assurance regarding the ultimate outcome of the Lawsuits.

As of the date this Form 8-K, the Company has also received demand letters from purported stockholders of the Company (i) alleging that the Proxy Statement was materially incomplete due to certain misrepresentations and omissions and demanding corrective disclosures to address such allegations or (ii) demanding access to the Company’s books and records to investigate certain aspects of the Merger (the “Letters”).

It is possible that additional, similar complaints may be filed or letters may be received, or that the Lawsuits described above may be amended. If this occurs, the Company does not intend to announce the filing or receipt of each additional, similar complaint, letter or any amended complaint, unless required by law.

The Company believes that the claims asserted in the Lawsuits and Letters are without merit. However, in order to moot the unmeritorious disclosure claims and alleviate the costs, risks and uncertainties inherent in potential litigation, the Company has determined to voluntarily supplement the Proxy Statement as described in this Form 8-K. Nothing in this Form 8-K shall be deemed an admission of the legal necessity or materiality under applicable laws of any of the disclosures set forth herein. To the contrary, the Company specifically denies all allegations set forth in the Lawsuits and Letters that any additional disclosure in the Proxy Statement was or is required.

Supplemental Disclosures

The following disclosures supplement the disclosures contained in the Proxy Statement and should be read in conjunction with the disclosures contained in the Proxy Statement, which should be read in its entirety. To the extent the information set forth herein differs from or updates information contained in the Proxy Statement, the information set forth herein shall supersede or supplement the information in the Proxy Statement. All page references are to pages in the Proxy Statement, and terms used below, unless otherwise defined, have the meanings set forth in the Proxy Statement. For clarity, new text within restated paragraphs from the Proxy Statement is highlighted with bold, underlined text.

On December 11, 2025, the Payoneer Board of Directors held a regularly scheduled meeting during which, among other things, management provided an update regarding recent discussions with Party E and Nuvei Parent. Subsequently, on December 14, 2025, the Payoneer Board of Directors reinstated the advisory committee (the “Advisory Committee”), consisting of Ms. Patsley, Christopher (Woody) Marshall and Mr. Williams via action by written consent to advise on and review with management and Payoneer’s advisors, as the case may be, exploratory strategic opportunities. In re-instating the Advisory Committee, the Payoneer Board of Directors was familiar with Mr. Marshall’s role as a general partner of TCV and his position as a director, member and limited partner of investment vehicles controlled by TCV. The Payoneer Board of Directors was further aware of Mr. Marshall’s and TCV’s professional relationship with Advent. The Payoneer Board of Directors did not believe that such relationship would impair Mr. Marshall’s independence or his ability to discharge his duties as a member of the Advisory Committee, including because such professional relationships are common among financial sponsors that make investments in the financial services industry, such as TCV and Advent, and neither Mr. Marshall nor TCV had any agreement or understanding with Advent concerning the Merger. Accordingly, the Payoneer Board of Directors did not believe that Mr. Marshall’s participation on the Advisory Committee presented a conflict of interest. Payoneer notes that investment vehicles sponsored by TCV have made investments in certain portfolio companies alongside investments by investment vehicles sponsored by Advent and that all such investments were made on arms’ length terms.

Later on December 30, 2025, the Advisory Committee held a meeting, at which representatives of Qatalyst Partners and Davis Polk were present, to review the December 30 Proposal. At the meeting, the Advisory Committee was informed that Davis Polk had previously represented Nuvei Parent and its affiliates in, among other matters, its take-private by Advent in 2024, and that Davis Polk continued to represent Nuvei Parent and its affiliates in other matters unrelated to the proposed transaction with Payoneer. The Advisory Committee did not believe that such matters presented a conflict of interest given such matters were unrelated to Payoneer’s negotiations with Nuvei Parent and such matters were not material to Davis Polk (such matters collectively generated approximately $6 million in revenue for Davis Polk from January 1, 2024 through the date of entry into the Merger Agreement, or less than 0.1% of Davis Polk’s revenues over the same period). Davis Polk’s representations of Nuvei Parent and its affiliates was also discussed at subsequent meetings of the Payoneer Board of Directors, and the Payoneer Board of Directors did not believe that Davis Polk’s participation presented a conflict of interest. Representatives of Qatalyst Partners summarized the principal terms of the proposal at such meeting and reviewed Nuvei Parent’s diligence process to date. Representatives of Qatalyst Partners also updated the Advisory Committee regarding discussions with Party E. Following discussion, the Advisory Committee expressed the view that the December 30 Proposal did not meet Payoneer’s expectations and supported representatives of Payoneer management and Qatalyst Partners (i) informing Nuvei Parent that its proposal did not meet expectations, (ii) continuing to provide Nuvei Parent with access to Payoneer management and additional non-public information of Payoneer to facilitate the submission of an improved proposal and (iii) initiating outreach to certain financial sponsors and strategic counterparties that the Advisory Committee believed were the most likely to have an interest in acquiring Payoneer.

(e) In the section of the Proxy Statement titled “The Merger (Proposal 1)— Summary of Qatalyst Partners’ Financial Analyses” the Selected Transactions Analysis table on page 55 is amended by replacing such table with the following:

Pursuant to the requirements of the Securities and Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.

Key factors that could cause actual results to differ materially include, but are not limited to, the expected timing and likelihood of completion of the Transaction, including the timing, receipt and terms and conditions of any required governmental and regulatory approvals of the Transaction; the occurrence of any event, change or other circumstances that could give rise to the termination of the Merger Agreement; the possibility that the Company's stockholders may not approve the Transaction; the risk that the parties may not be able to satisfy the conditions to the Transaction in a timely manner or at all; risks related to disruption of management time from ongoing business operations due to the Transaction; the risk that any announcements relating to the Transaction could have adverse effects on the market price of the Company's common stock; the risk that the Transaction and its announcement could have an adverse effect on the parties' business relationships and business generally, including the ability of the Company to retain customers and retain and hire key personnel and maintain relationships with their suppliers and customers, and on their operating results and businesses generally; the risk of unforeseen or unknown liabilities; customer, stockholder, partner, regulatory and other stakeholder approvals and support; the risk of unexpected future capital expenditures; the risk of potential litigation relating to the Transaction that could be instituted against the Company or its directors and/or officers; the risk associated with third party contracts containing material consent, anti-assignment, transfer or other provisions that may be related to the Transaction which are not waived or otherwise satisfactorily resolved; the risk of various events that could disrupt operations, including severe weather, such as droughts, floods, avalanches and earthquakes, cybersecurity attacks, wars, security threats and governmental response to them, and technological changes; the risks of labor disputes, changes in labor costs and labor difficulties; and the risks resulting from other effects of industry, market, economic, legal or legislative, political or regulatory conditions outside of the Company's control. All such factors are difficult to predict and are beyond our control, including those detailed in the Company's annual report on Form 10-K for the fiscal year ended December 31, 2025 (and which is available at: https://www.sec.gov/Archives/edgar/data/1845815/000110465926020487/payo-20251231x10k.htm), quarterly reports on Form 10-Q and other documents subsequently filed by the Company with the Securities and Exchange Commission (“SEC”) (and that are available at
