Demand for the Company’s staffing services increased during the first quarter of 2017 from the previous quarter and we were able to expand our billable consultant-base in the quarter.

Commenting on the Company’s 2017 first quarter results, Vivek Gupta, Mastech Digital’s Chief Executive Officer stated, “It was satisfying to see higher levels of activity during the quarter and our ability to grow revenues and consultants-on-billing both year-over-year and sequentially . During the quarter, we continued to invest in our sales and recruitment organizations, which positions us to take full advantage of growth opportunities in the subsequent quarters of 2017.”

Commenting on the Company’s financial position, Jack Cronin, Mastech Digital’s Chief Financial Officer, stated, “At March 31, 2017, we had bank debt, net of cash balances on hand, of $12.4 million and approximately $9.6 million of borrowing capacity available to us under our revolving credit line. During the quarter, the increase in bank debt largely reflected an investment in operating working capital to support our growth.”

Use of non-GAAP Measures:

This press release contains non-GAAP financial measures to supplement our financial results presented on a GAAP basis. The presentation of these financial measures is not intended to be considered in isolation or as a substitute for, or superior to, financial information prepared and presented in accordance with GAAP. Investors are cautioned that there are material limitations associated with the use of non-GAAP financial measures as an analytical tool. Reconciliations of these non-GAAP measures to their comparable GAAP measures are included in the attached financial tables.

We believe that providing non-GAAP net income and non-GAAP diluted earnings per share offers investors useful supplemental information about the financial performance of our business, enables comparison of financial results between periods where certain items may vary independent of business performance, and allows for greater transparency with respect to key metrics used by management in operating our business. Additionally, management uses these non-GAAP financial measures in evaluating the Company’s performance.

Specifically, the non-GAAP financial measures contained herein exclude the following expense items:

Amortization of acquired intangible assets: We amortize intangible assets acquired in connection with our June 2015 acquisition of Hudson IT. We exclude these amortization expenses in our non-GAAP financial measures because we believe it allows investors to make more meaningful comparisons between our operating results and those of other companies within our industry and facilitates a helpful comparison of our results with other periods.

Stock-based compensation expenses: We incur material recurring expense related to non-cash, stock-based compensation. We exclude these expenses in our non-GAAP financial measures because we believe that it provides investors with meaningful supplemental information regarding operational performance. In particular, because of varying available valuation methodologies, subjective assumptions and the variety of award types that companies can use under ASC 718, we believe that providing non-GAAP financial measures that exclude these expenses allows investors to make more meaningful comparisons between our operating results and those of other companies within our industry and facilitates comparison of our results with other periods.

Severance charges: From time to time, we incur severance expense related to the termination by the Company of leadership personnel. While it is probable that these expenses will occur in the future, we believe that providing non-GAAP financial measures that exclude these expenses are useful for investors to understand the effects of these items on our total operating expenses and facilitate comparison of our results with other periods.

Forward-Looking Statements:

Certain statements contained in this release are forward-looking statements based on management’s expectations, estimates, projections and assumptions. Words such as “expects,” “anticipates,” “plans,” “believes,” “scheduled,” “estimates” and variations of these words and similar expressions are intended to identify forward-looking statements, which include but are not limited to (i) projections of revenues, earnings, and cash flow, and (ii) the expected completion of the acquisition, the time frame in which this will occur, the expected benefits to Mastech Digital from completing the acquisition and the expected performance of Mastech Digital following completion of the acquisition. These statements are based on information currently available to the Company and it assumes no obligation to update the forward-looking statements as circumstances change. These statements are not guarantees of future performance and involve certain risks and uncertainties, which are difficult to predict. Therefore, actual future results and trends may differ materially from what is forecast in forward-looking statements due to a variety of factors, including, without limitation, the level of market demand for its services, the highly competitive market for the types of services offered by the Company, the impact of competitive factors on profit margins, market conditions that could cause the Company’s customers to reduce their spending for its services, and the Company’s ability to create, acquire and build new lines of business, to attract and retain qualified personnel, reduce costs and conserve cash, and other risks that are described in more detail in the Company’s filings with the Securities and Exchange Commission including its Form 10-K for the year ended December 31, 2016.
