LAFAYETTE, La. (AP) — IberiaBank Corp. has agreed to acquire Cameron Bancshares Inc., which operates in southwestern Louisiana, in a stock exchange valued at $133 million. Lake Charles-based Cameron, which operates as Cameron State Bank, has 22 offices in the Lake Charles area. Lafayette-based IberiaBank says the deal has been approved by the boards of both companies. Cameron still needs the approval of its shareholders and banking regulators must approve the acquisition. Cameron shareholders will receive just under 3.5 shares of IberiaBank stock for each share of Cameron. The deal is expected to close in the second quarter.
