Additionally, gross margins improved during the quarter by 140-basis points when compared to a year ago, and we successfully reduced S,G&A expenses by 3% from the corresponding quarter of 2023.

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, our July 2017 acquisition of the services division of InfoTrellis, Inc. and our October 2020 acquisition of AmberLeaf Partners. 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 expenses 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.
