Suffolk Bancorp in Riverhead, N.Y., said Monday that it had earned $6 million in the third quarter, down 2% from the year earlier but that per-share earnings rose a penny, to $1.66.
The slight decline could be attributed to a six-basis-point drop in its net interest margin, to 5.08%.
In late trading Monday, shares in the $1.6 billion-asset Suffolk were down nearly 5%, to $32.77.
