Zions Bancorp boosted the size of planned stock sales by $175 million and announced it will sell $150 million of warrants.
The Utah banking company, which has a market value of about $4.3 billion, said the moves will further boost its capital.
The company in March announced equity-distribution deals with Deutsche Bank AG and Goldman Sachs Group Inc. for $250 million in stock after a similar-sized effort with the companies that began in September. About $125 million remains to be sold under the March agreement.
Zions has reported improved loan data in recent quarters, with chargeoffs and loss provisions falling. But it has yet to return to profitability.
