Risk factors and legal proceedings

The risks Haymaker Acquisition Corp. 4 names in Item 1A of its 10-K filed Mar 30, 2026: 10 risks under these headings, as written.⁴

• Risks Relating to our Search for, and Consummation of or Inability to Consummate, a Business Combination
• Risks Relating to the Post-Business Combination Company
• Risks Relating to Acquiring or Operating a Business in Foreign Countries
• Risks Relating to our Management Team
• Risks Relating to our Securities and Shareholder Rights
• We may seek Business Combination opportunities with a high degree of complexity that require significant operational improvements, which could delay or prevent us from achieving our desired results.
• Our search for an initial Business Combination, and any target business with which we may ultimately consummate an initial Business Combination, may be materially adversely affected by current global geopolitical conditions and armed conflicts in the Ukraine and Russia and in the Middle East between United States, Israel and Iran and others, as well as by other events that are outside of our control.
• Military or other conflicts in Ukraine, between the United States, Israel and Iran and others and other in the Middle East and Southwest Asia or other armed hostilities may lead to increased volume and price volatility for publicly traded securities, or affect the operations or financial condition of potential target companies, which could make it more difficult for us to consummate an initial Business Combination.
• If we are unable to consummate our initial Business Combination within the Combination Period, our Public Shareholders may be forced to wait beyond July 28, 2026, before redemption from our Trust Account.
• Since only holders of our Class B Ordinary Shares have the right to vote on the appointment of directors, NYSE considers us to be a “controlled company” within the meaning of the NYSE Rules and, as a result, we may qualify for exemptions from certain corporate governance requirements.
• Members of our Management Team and affiliated companies may in the future be involved in civil disputes or governmental investigations unrelated to our business.
• The securities in which we invest the funds held in the Trust Account could bear a negative rate of interest, which could reduce the interest income available for payment of taxes or reduce the value of the assets held in Trust Account such that the Redemption Price received by our Public Shareholders may be less than $11.41 per Public Share (as of December 31, 2025).

Legal proceedings

To the knowledge of our Management Team, there is no material litigation currently pending or contemplated against us, any of our subsidiaries any of our officers or directors in their capacity as such or against any of our property.
