HOME BANCORP, INC.

A U.S. Securities and Exchange Commission rule allows us to furnish proxy materials to shareholders over the internet. As a result, beginning on or about April 2, 2026, we sent by mail a Notice of Internet Availability of Proxy Materials (the “Notice”), containing instructions on how to access our proxy materials, including our proxy statement and 2025 Annual Report to shareholders, over the internet and how to vote. Internet availability of our proxy materials is designed to expedite receipt by shareholders and lower the cost and environmental impact of the Annual Meeting. However, if you received the Notice and would prefer to receive paper copies of the proxy materials, please follow the instructions included in the Notice of Internet Availability of Proxy Materials or send an email toinvestorvote@computershare.com with “Proxy Materials Home Bancorp, Inc.” in the subject line. Include in the message your full name and address, plus the control number located on the Notice, and state in the email that you want a paper copy of the annual meeting materials.

If you have received paper copies of the proxy materials and would prefer to receive only electronic copies of such materials in the future, please contact our registrar and transfer agent, Computershare, at 1-800-368-5948, or write them at Computershare, Investor Services, 150 Royall Street, Suite 101, Canton, MA 02021.

If you hold our stock through more than one account, you may receive multiple copies of these proxy materials and will have to follow the instructions of each in order to vote all of your shares.
