TransDigm  (TDG)  said Tuesday that it earned $3.02 a share in the first quarter compared to $2.86 a share a year ago.

The earnings were exactly what a poll of analysts had expected the company to earn, but its revenues came in under expectations at $873.2 million versus an $891.8 million estimate.

The aerospace components maker lightened up on its own estimates for full year results and now expects 2017 earnings per share of $12.09-$12.33, versus an analyst average $12.22 estimate.

It expects $3.53-3.57 billion in full-year revenue, versus an analyst consensus of $3.56 billion.

In January Short-seller Andrew Left identified TransDigm as a good short-selling candidate saying, "TransDigm's business model is to aerospace as Valeant  (VRX) was to the pharmaceutical industry."

The Cleveland, Ohio-based company is a leading aerospace components manufacturer with sales to government agencies accounting for approximately 30% of its revenue. Left noted that TransDigm's single largest customer is the Department of Defense, followed by Boeing  (BA) and Airbus (EADSY) .
