IberiaBank Corp. and Home Bancorp., both Lafayette financial institutions, reported hefty increases in third-quarter earnings.

IberiaBank Corp. reported third-quarter earnings of $20.8 million, or 73 cents per share, compared with $16.1 million, or 54 cents per share, a year ago.

The holding company for IberiaBank said its earnings were lowered by $3 million in pre-tax costs related to the acquisition of Fort Myers, Fla.-based Florida Gulf Bancorp Inc. and the conversion of its 10 branches.

The third-quarter earnings were well above the 56 cents forecast by Wall Street analysts surveyed by Thomson Reuters.

Meanwhile, Home Bancorp said the acquisition of GS Financial Corp. helped boost earnings to $3.1 million, or 42 cents per share, more than double the $1 million, or 13 cents per share, for the same period a year earlier.

Home Bancorp is the parent company of Home Bank.

The third-quarter results included $1.4 million of pre-tax expenses related to the GS Financial deal, which included five offices in the New Orleans area.
