Certain comments in this presentation contain certain forward looking statements (as defined in the Securities Exchange Act of 1934 and the regulations thereunder). Forward looking statements are not historical facts but instead represent only the beliefs, expectations or opinions of Home Bancorp, Inc. and its management regarding future events, many of which, by their nature, are inherently uncertain. Forward looking statements may be identified by the use of such words as: “believe”, “expect”, “anticipate”, “intend”, “plan”, “estimate”, or words of similar meaning, or future or conditional terms such as “will”, “would”, “should”, “could”, “may”, “likely”, “probably”, or “possibly.” Forward looking statements include, but are not limited to, financial projections and estimates and their underlying assumptions; statements regarding plans, objectives and expectations with respect to future operations, products and services; and statements regarding future performance. Such statements are subject to certain risks, uncertainties and assumption, many of which are difficult to predict and generally are beyond the control of Home Bancorp, Inc. and its management, that could cause actual results to differ materially from those expressed in, or implied or projected by, forward looking statements. The following factors, among others, could cause actual results to differ materially from the anticipated results or other expectations expressed in the forward looking statements: (1) economic and competitive conditions which could affect the volume of loan originations, deposit flows and real estate values; (2) the levels of noninterest income and expense and the amount of loan losses; (3) competitive pressure among depository institutions increasing significantly; (4) changes in the interest rate environment causing reduced interest margins; (5) general economic conditions, either nationally or in the markets in which Home Bancorp, Inc. is or will be doing business, being less favorable than expected; (6) political and social unrest, including acts of war or terrorism; (7) we may not fully realize all the benefits we anticipated in connection with our acquisitions of other institutions or our assumptions made in connection therewith may prove to be inaccurate; (8) cyber incidents or other failures, disruptions or security beaches; or (9) legislation or changes in regulatory requirements adversely affecting the business of Home Bancorp, Inc. Home Bancorp, Inc. undertakes no obligation to update these forward looking statements to reflect events or circumstances that occur after the date on which such statements were made. As used in this report, unless the context otherwise requires, the terms “we,” “our,” “us,” or the “Company” refer to Home Bancorp, Inc. and the term the “Bank” refers to Home Bank, N.A., a national bank and wholly owned subsidiary of the Company. In addition, unless the context otherwise requires, references to the operations of the Company include the operations of the Bank. For a more detailed description of the factors that may affect Home Bancorp’s operating results or the outcomes described in these forward-looking statements, we refer you to our filings with the Securities and Exchange Commission, including our annual report on Form 10-K for the year ended December 31, 2024.
