In a press release accompanying the earnings, PacWest’s Chief Executive Matt Wagner said the company is “very strong and well-positioned” and said the CapitalSource merger has already paid off.

“The benefits of the CapitalSource merger are apparent in our second quarter results: record adjusted net earnings of $64 million, new loan and lease fundings of $881 million, organic loan and lease growth of $143 million, and significant progress in meeting our deposit transformation and cost savings targets,” Wagner said.

PacWest’s shares on Tuesday closed up slightly to $41.19 on the Nasdaq.
