Bank of America shares drop more than 4% after third quarter revenue miss and regulatory penalty

Bank of America posted a sharp decline to third-quarter profit after being hit with a $1.2 billion penalty by the U.S. Treasury Department.

Shares of the bank fell more than 4% in premarket trading.

Here's what the company reported:

Earnings per share: 91 cents, may not compare with $1.10 LSEG estimate

Revenue: $30.12 billion vs. $30.69 billion estimate

The bank's profit fell 17% to $6.93 billion, or 91 cents a share. Excluding the penalty, which sapped income by 17 cents, EPS would've been $1.08 a share.

Revenue rose 3.2% to $30.12 billion in the quarter, below expectations by about $570 million, largely on misses from Wall Street trading operations.

Fixed income trading revenue fell 17% to $2.55 billion on weakness in mortgages, municipals, and credit activity. That is roughly $450 million below the StreetAccount estimate.

Equities trading revenue climbed 10% to $2.51 billion, but that was also below analysts' expectations, by nearly $300 million.

The Treasury episode, in which U.S. regulators said the company failed to report billions of dollars in suspicious transactions, will inevitably spark questions as to whether CEO Brian Moynihan has a handle on controls at the second-biggest U.S. bank by assets.

Moynihan took the helm in 2010 and spent the early years of his tenure making amends for mortgage-related abuses in the aftermath of the 2008 financial crisis. Now, questions arise as to whether there are any more risk-management issues waiting to be found.

The Treasury announcement adds 11th-hour intrigue to what was an otherwise fairly routine bank earnings week. On Tuesday, JPMorgan Chase, Goldman Sachs, Citigroup and Wells Fargo posted mixed results, with JPMorgan missing EPS and revenue estimates for the first time in years.
