With some of its newly reported numbers referred to as a "disappointment" by Matt Wagner , president and CEO of Los Angeles-based bank PacWest , the bank is looking ahead toward better days - particularly toward the closure of its buy of Durham-based Square 1 Bank , a deal worth an estimated $849 million. Wagner, releasing statements alongside an earnings announcement that disclosed negative net loan and lease growth for the quarter, said the merger with Square 1 was on track to close in the fourth quarter.
