Park Electrochemical (NYSE:PKE) said Thursday that its second-quarter earnings barely beat expectations, driven by improved sales, though revenue fell short of estimates, causing shares to fall.

The Melville, New York-based company posted net earnings of $9.45 million, or 46 cents a share, compared with $4.76 million, or 23 cents a share, in the same quarter last year.

The results were marginally ahead of average analyst estimates of 45 cents, according to a Thomson Reuters poll.

Revenue for the maker of high-technology digital materials was $54.5 million, up from $42.52 million a year ago, but missing the Street’s view of $59.32 million.
