Exhibit 99.1

FOR IMMEDIATE RELEASE:

Mastech Holdings, Inc. Reports Third Quarter 2014 Results:

PITTSBURGH, PA – October 22, 2014 - Mastech Holdings, Inc. (NYSE MKT: MHH), a national provider of Information Technology staffing services, announced today its financial results for the third quarter ended September 30, 2014.

Third Quarter Results:

Revenues from continuing operations for the third quarter of 2014 totaled $28.6 million, which represented a 4% sequential improvement over second quarter 2014 performance and a modest increase over the corresponding quarter last year. Gross profit from continuing operations in the third quarter of 2014 was $5.2 million which compared to $5.1 million in the second quarter of 2014 and $5.3 million in the third quarter of 2013. Consolidated net income from continuing operations for the third quarter 2014 totaled $879,000 or $0.20 per diluted share, which was in-line with last quarter’s performance and compared to $999,000 or $0.23 per diluted share during the same period last year.

Demand for our IT staffing services remained in-line with activity levels of a quarter ago. Our ratio of new assignment wins-to-activity levels improved during the recent quarter and, accordingly, we were able to increase our billable consultant-base by approximately 4-percent. Gross margins in the third quarter of 2014 were 18.3% compared to 18.9% reported a year earlier. Compensation increases in excess of bill rate increases and slightly lower margins on new assignments in our wholesale channel impacted overall margins during the quarter.

Kevin Horner, Mastech’s Chief Executive Officer stated, “I’m pleased to report that we have essentially recovered all of our billable consultant headcount that was lost in the surprise project termination during the previous quarter. As I communicated in our last earnings call, third quarter’s revenue and gross profit performance would be impacted by this unexpected project termination. As a result of this recovery, we were able to achieve 4% sequential growth in both revenues and billable consultants during the third quarter. Additionally, we continued to invest for growth during the quarter by ramping-up the production side of our business with the aggressive hiring of recruitment resources at both of our facilities in India and sales staff in the U.S. While these hires constrained our bottom-line results in the third quarter, they will allow us to better service the demand side of our business going forward.”

Commenting on the Company’s financial position, Jack Cronin, Chief Financial Officer, stated, “Our financial position at September 30, 2014 remains strong, with no short-term borrowings outstanding, cash balances on hand of $2.5 million and $17.4 million of borrowing capacity. During the quarter, the Company purchased for Treasury 32,271 shares of common stock, at an average share price of $12.14, and have approximately 495,000 shares that are available for purchase under our existing stock repurchase program.”
