HBI-SOF See Front of Stock Order Form (8) ASSOCIATES/ACTING IN CONCERT (continued from front of Stock Order Form) Associate – The term “associate” of a person means: (1) any corporation or organization (other than Hoyne Savings Bank, Hoyne Bancorp, Inc. or a majority-owned subsidiary of any of those entities) of which the person is a senior officer, partner or, directly or indirectly, 10% beneficial stockholder; (2) any trust or other estate in which the person has a substantial beneficial interest or serves as a trustee or in a fiduciary capacity; and (3) any relative or spouse of such person, or any relative of such spouse, who either has the same home as the person or who is a director or officer of Hoyne Savings Bank or Hoyne Bancorp, Inc. Acting in concert – The term “acting in concert” means persons seeking to combine or pool their voting or other interests in the securities of an issuer for a common purpose, pursuant to any contract, understanding, relationship, agreement or other arrangement, whether written or otherwise. In general, a person or company that acts in concert with another person or company shall also be deemed to be acting in concert with any person or company who is also acting in concert with that other party, except that any tax-qualified employee stock benefit plan will not be deemed to be acting in concert with its trustee or a person who serves in a similar capacity solely for the purpose of determining whether common stock held by the trustee and common stock held by the employee stock benefit plan will be aggregated. Our directors are not treated as associates of each other solely because of their membership on the board of directors. We have the right to determine, in our sole discretion, whether purchasers are associates or acting in concert. Persons with the same address, whether or not related, and persons exercising subscription rights through qualifying accounts registered to the same address will be deemed to be acting in concert unless we determine otherwise. Please see the Prospectus section entitled “The Conversion and Offering – Additional Limitations on Common Stock Purchases” for more information on purchase limitations. (10) ACKNOWLEDGMENT AND SIGNATURE(S) (continued from front of Stock Order Form) I agree that, after receipt by Hoyne Bancorp, Inc., this Stock Order Form may not be modified or canceled without Hoyne Bancorp, Inc.’s consent, and that if withdrawal from a deposit account has been authorized, the authorized amount will not otherwise be available for withdrawal. Under penalty of perjury, I certify that (1) the Social Security Number or Tax ID information and all other information provided hereon are true, correct and complete, (2) I am purchasing shares solely for my own account and that there is no agreement or understanding regarding the sale or transfer of such shares, or my right to subscribe for shares, and (3) I am not subject to backup withholding tax [cross out (3) if you have been notified by the IRS that you are subject to backup withholding]. I acknowledge that my order does not conflict with the overall purchase limitation of $300,000 in all categories of the offering combined, for any person or entity, together with any associate or group of persons acting in concert, as set forth in the plan of conversion and the Prospectus dated _________, 2025. Subscription rights pertain to those eligible to subscribe in the Subscription Offering. Subscription rights are only exercisable by completing and submitting an original Stock Order Form, with full payment for the shares subscribed for. Federal regulations prohibit any person from transferring or entering into any agreement directly or indirectly to transfer the legal or beneficial ownership of subscription rights, or the underlying securities, to the account of another. I ACKNOWLEDGE THAT THE SHARES OF COMMON STOCK ARE NOT DEPOSITS OR SAVINGS ACCOUNTS AND ARE NOT INSURED OR GUARANTEED BY HOYNE SAVINGS BANK, THE FEDERAL DEPOSIT INSURANCE CORPORATION OR ANY OTHER GOVERNMENT AGENCY. If anyone asserts that the shares of common stock are federally insured or guaranteed, or are as safe as an insured deposit, I should call the Office of the Comptroller of the Currency. I further certify that, before subscribing for shares of the common stock of Hoyne Bancorp, Inc., I received the Prospectus dated __________, 2025, and I have read the terms and conditions described in the Prospectus, including disclosure concerning the nature of the security being offered and the risks involved in the investment, described by Hoyne Bancorp, Inc. in the “Risk Factors” section, beginning on page __. Risks include, but are not limited to, the following: Risks Related to Our Lending Activities 1. We intend to increase the origination of our commercial loan portfolio which could expose us to increased lending risks and related loan losses. 2. If our allowance for credit loan losses is not sufficient to cover actual loan losses, our results of operations would be negatively affected. 3. The geographic concentration of our loan portfolio and lending activities makes us vulnerable to a downturn in our local market area. 4. The level of our commercial real estate loan portfolio may subject us to additional regulatory scrutiny. 5. Our business may be adversely affected by credit risk associated with residential property. 6. A deterioration in economic conditions in our markets could result in increases in our level of non-performing loans and/or reduce demand for our products and services, which could have an adverse effect on our results of operations. Risks Related to Our Business Strategy 7. We may not achieve significant profitability from our business strategies and growth plan in the near term. 8. Our business strategy includes commercial real estate (including commercial construction) and commercial and industrial loan growth, and our financial condition and results of operations could be negatively affected if we fail to grow or fail to manage our growth effectively. Growing our operations could also cause our expenses to increase faster than our revenues. 9. We depend on our management team and other key personnel to implement our business strategy and execute successful operations and we could be harmed by the loss of their services or the inability to hire additional personnel. 10. We are subject to certain risks if we are able to grow through opportunistic mergers and acquisitions. Risks Related to Our Business and Industry Generally 11. We are dependent on our information technology and telecommunications systems and third-party service providers; systems failures, interruptions and cybersecurity breaches could have a material adverse effect on us. 12. Ineffective liquidity management could adversely affect our financial results and condition. 13. Strong competition within our market area could hurt our profits and slow growth. 14. We are a community institution and our ability to maintain our reputation is critical to the success of our business. The failure to do so may adversely affect our performance. 15. Security breaches and cybersecurity threats could compromise our information and expose us to liability, which would cause our business and reputation to suffer. 16. We must keep pace with technological change to remain competitive. 17. Because the nature of the financial services business involves a high volume of transactions, we face significant operational risks. 18. Acts of terrorism and other external events could impact our business. 19. Regulation of the financial services industry is intense, and we may be adversely affected by changes in laws and regulations. 20. A tightening of credit markets and liquidity risk could impair our ability to fund operations and jeopardize our financial condition. 21. Inflation can have an adverse impact on our business and on our customers. 22. Changes in interest rates could affect our profits and the value of our assets and liabilities. 23. We are subject to an extensive body of accounting rules and best practices. Periodic changes to such rules may change the treatment and recognition of critical financial line items and affect our profitability. 24. Noncompliance with the USA PATRIOT Act, Bank Secrecy Act, or other laws and regulations could result in fines or sanctions and impact our ability to complete transactions that require regulatory approval. 25. The cost of additional finance and accounting systems, procedures, compliance and controls in order to satisfy our new public company reporting requirements will increase our expenses. 26. Changes in management’s estimates and assumptions may have a material impact on our financial statements and our financial condition or operating results. 27. We are subject to environmental liability risk associated with lending activities or properties we own. Risks Related to the Offering 28. The future price of our common stock may be less than the $10.00 per share purchase price in the offering. 29. The capital we raise in the offering may negatively impact our return on equity until we can fully implement our business plan. This could negatively affect the trading price of our shares of common stock. 30. We have broad discretion in using the proceeds of the offering. Our failure to effectively deploy the net proceeds of the offering may have an adverse effect on our financial performance and the value of our common stock. 31. There may be a limited trading market in our common stock, which would hinder your ability to sell our common stock and may lower the market price of the stock. 32. Our stock-based and other benefit plans will increase our costs, which will reduce our net income. 33. The implementation of our stock-based benefit plans may dilute your ownership interest. 34. Various factors may make takeover attempts more difficult to achieve. 35. You may not receive dividends on our common stock. 36. You may not be able to sell your shares of common stock until you have received a statement reflecting ownership of shares, which will affect your ability to take advantage of changes in the stock price immediately following the offering. 37. You may not revoke your decision to purchase Hoyne Bancorp, Inc. common stock in the subscription and community offerings after you send us your order. 38. We are an emerging growth company, and any decision on our part to comply only with certain reduced reporting and disclosure requirements applicable to emerging growth companies could make our common stock less attractive to investors. 39. The distribution of subscription rights could have adverse income tax consequences. 40. The certificate of incorporation of Hoyne Bancorp, Inc. designates the federal and state courts located in the State of Delaware as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers or employees. Risks Related to the Charitable Foundation 41. The contribution to the charitable foundation will dilute your ownership interest and adversely affect net income in 2025. 42. Our contribution to the charitable foundation may not be deductible for federal income tax purposes. By executing this form, the investor is not waiving any rights under federal or state securities laws, including the Securities Act of 1933 and the Securities Exchange Act of 1934.
