Bank of America shares open 7% lower after third-quarter revenue miss and Treasury penalty

Bank of America on Wednesday posted a sharp profit decline after being hit with a $1.2 billion penalty by U.S. regulators, while revenue also disappointed after trading operations generated about $750 million less than expected.

Shares of the bank fell more than 7% in premarket trading.

Here's what the company reported:

The bank's third-quarter 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.

Companywide revenue rose 3.2% to $30.12 billion in the quarter, on an FTE basis, but that was 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 trading disappointment comes after CEO Brian Moynihan told analysts last month that trading revenue would be roughly flat; instead the combined bond and stock trading results fell by 5%.

Investment banking revenue dropped 11% to $1.8 billion, roughly in line with expectations and Moynihan's September guidance.

In a research note published Wednesday, Wells Fargo analyst Mike Mayo called the firm's capital markets results "easily worst in class" for the quarter.

Net interest income, a key profitability driver watched closely by Bank of America investors, rose 7.9% to $16.6 billion, slightly edging out the $16.53 billion StreetAccount estimate.

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 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 fine, announced on Tuesday, 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.

Correction: Bank of America reported third-quarter revenue on an FTE basis of $30.12 billion compared with LSEG estimates of $30.69 billion. An earlier version misstated the comparison.
