Shares of F.N.B. Corp. fell sharply Wednesday, after the Hermitage, Pa., company warned that it expects to report a fourth-quarter loss of between $17 million and $21 million.
The $8.4 billion-asset F.N.B. said late Tuesday that the expected loss was driven by an increase in its loss provision related to loans it made in Florida, as well as $19 million of impairment charges on its investments. It had earned $17.1 million a year earlier.
