PITTSBURGH, PA – February 1, 2012 – Mastech Holdings, Inc. (NYSE Amex: MHH – News), a national provider of Information Technology and Specialized Healthcare staffing services, announced today its financial results for the fourth quarter and full year ended December 31, 2011.

Fourth Quarter Results:

Revenues for the quarter were $23.9 million and represented an 18% increase over the corresponding quarter last year and a 2% improvement over third quarter 2011 results. Gross margins in the 2011 quarter totaled 19.3% compared to 19.7% for the 2010 quarter.

The 2011 fourth quarter results included severance expense equal to $0.05 per diluted share, related to the elimination of several executive positions during the quarter.

Demand for our IT staffing services remained solid during the fourth quarter when considering the normal year-end industry trends. Market conditions in healthcare staffing remained largely positive and we were able to achieve sequential revenue growth for the sixth consecutive quarter.

Revenue for the year totaled $89.4 million, or 24% higher than 2010 revenues of $71.8 million. Gross margins for the full year 2011 were 19.6% which was in-line with last year’s gross margin performance.
