HOME BANCORP, INC.

ABOUT THE ANNUAL MEETING OF SHAREHOLDERS

We are furnishing this proxy statement to holders of common stock of Home Bancorp, Inc. (the “Company”), the holding company of Home Bank, N.A. (the “Bank”). We are soliciting proxies on behalf of our Board of Directors to be used at the Annual Meeting of Shareholders (“Annual Meeting”) to be held at the Petroleum Club of Lafayette, located at 111 Heymann Boulevard, Lafayette, Louisiana, on Tuesday, May 12, 2026 at 10:00 a.m., Central Daylight Time, and at any adjournment thereof, for the purposes set forth in the attached Notice of Annual Meeting of Shareholders. This proxy statement is first being made available or mailed to shareholders on or about April 2, 2026.

Why did I receive a one-page notice in the mail regarding the internet availability of proxy materials instead of a full set of proxy materials?

Pursuant to rules adopted by the U.S. Securities and Exchange Commission (the “SEC”), we have elected to provide access to our proxy materials via the internet. Internet delivery of our proxy materials allows us to provide our shareholders with the information they need timely, while lowering the costs of delivery and reducing the environmental impact of our Annual Meeting. Accordingly, we are sending a Notice of Internet Availability of Proxy Materials, which we refer to as the Notice, to our shareholders and beneficial owners as of the record date for the Annual Meeting. All shareholders will have the ability to access the proxy materials on a website referred to in the Notice or, if they prefer, request to receive a printed set of the proxy materials. Instructions on how to access the proxy materials over the internet or to request a printed copy may be found in the Notice. In addition, shareholders may request to receive proxy materials in printed form by mail or electronically on an ongoing basis by calling Computershare at 1-800-368-5948 or sending an email toinvestorvote@computershare.com
