Shares of the company fell 8 percent to $2.80 in extended trading, after closing at $3.05 Monday on Nasdaq.
In a preliminary report, the company said net loss for the first quarter was $85 million, compared with $52.5 million in the year-ago period.
For the first quarter, Puerto Rico's largest bank sees net interest income of about $269 million, compared with $272.5 million last year.

Separately, the bank said it has commenced a public offering of depositary shares, each representing an interest in a share of its series D preferred stock, to raise $900 million.
