Lafayette-based Home Bancorp Inc. reported fourth-quarter net income of $2.1 million, or 30 cents per share, compared to $1.2 million, or 13 cents per share, a year earlier.

Net income for the year was $5.1 million, or 71 cents per share, compared to $4.7 million, or 62 cents per share, a year earlier.

Home Bancorp is holding company of Home Bank, a federally chartered savings and loan.

Home Bank’s results were affected by the acquisition of GS Financial Corp., the holding company of Guaranty Savings Bank of Metairie. The acquisition costs lowered Home Bancorp’s fourth-quarter earnings by $400,000, or 6 cents per share.

In a news release, Home President and Chief Executive Officer John W. Bordelon said the company’s prospects for 2012 are strong due to the economic health of the bank’s markets.
