Paso Robles-based Heritage Oaks Bancorp’s second-quarter profits jumped 25.1 percent to $2.9 million.

Net income from its acquisition of Mission Community Bancorp in February drove the increase, Heritage Oaks said in a July 28 earnings release. The bank’s loans grew 46.9 percent to $1.1 billion, year-over-year, as it added $280.7 million of Mission’s loans to its books. Deposits jumped 57.8 percent to $1.4 billion.

Heritage Oaks said it recorded $1.3 million in costs related to the merger during the second quarter. Total costs related to the deal this year are estimated to be $10.2 million, with $8 million already incurred.

“Since the merger closed on Feb. 28, 2014, our team has focused on the smooth transition and integration of the Mission Community Bank customers and operations into our organization. On July 19, we successfully completed the system conversion for the former Mission customers and we are now all on one system,” Heritage Oaks President and CEO Simone Lagomarsino said in a statement.

Heritage Oaks has retained 97 percent of Mission Community’s deposits, she noted.

With $1.7 billion in assets, Heritage Oaks is the largest bank based in the Tri-Counties. The firm has branches throughout San Luis Obispo County and one in downtown Santa Barbara. It has opened a loan production office in Oxnard as it prepares to expand into Ventura County.
