About Non-GAAP Financial Measures

Perficient provides non-GAAP financial measures for EBITDAS (earnings before interest, income taxes, depreciation, amortization, and stock compensation), adjusted net income, and adjusted earnings per share data as supplemental information regarding Perficient's business performance. Perficient believes that these non-GAAP financial measures are useful to investors because they provide investors with a better understanding of Perficient's past financial performance and future results. Perficient's management uses these non-GAAP financial measures when it internally evaluates the performance of Perficient's business and makes operating decisions, including internal operating budgeting, performance measurement, and the calculation of bonuses and discretionary compensation.  Management excludes stock-based compensation related to employee stock options and restricted stock awards, the amortization of intangible assets, acquisition costs, adjustments to the fair value of contingent consideration, and income tax effects of the foregoing, when making operational decisions.

Perficient believes that providing the non-GAAP financial measures to its investors is useful because it allows investors to evaluate Perficient's performance using the same methodology and information used by Perficient's management. Specifically, adjusted net income is used by management primarily to review business performance and determine performance-based incentive compensation for executives and other employees.  Management uses EBITDAS to measure operating profitability, evaluate trends, and make strategic business decisions.

Non-GAAP financial measures are subject to inherent limitations because they do not include all of the expenses included under GAAP and because they involve the exercise of discretionary judgment as to which charges are excluded from the non-GAAP financial measure. However, Perficient's management compensates for these limitations by providing the relevant disclosure of the items excluded in the calculation of EBITDAS, adjusted net income, and adjusted earnings per share. In addition, some items that are excluded from adjusted net income and adjusted earnings per share can have a material impact on cash. Management compensates for these limitations by evaluating the non-GAAP measure together with the most directly comparable GAAP measure. Perficient has historically provided non-GAAP financial measures to the investment community as a supplement to its GAAP results to enable investors to evaluate Perficient's business performance in the way that management does. Perficient's definition may be different from similar non-GAAP financial measures used by other companies and/or analysts.

The non-GAAP adjustments, and the basis for excluding them, are outlined below:

Amortization of Intangible Assets

Perficient has incurred expense on amortization of intangible assets primarily related to various acquisitions. Management excludes these items for the purposes of calculating EBITDAS, adjusted net income, and adjusted earnings per share. Perficient believes that eliminating this expense from its non-GAAP financial measures is useful to investors because the amortization of intangible assets can be inconsistent in amount and frequency, and is significantly impacted by the timing and magnitude of Perficient's acquisition transactions, which also vary substantially in frequency from period to period.

Acquisition Costs

Perficient incurs transaction costs related to acquisitions which are expensed in its GAAP financial statements.  Management excludes these items for the purposes of calculating EBITDAS, adjusted net income, and adjusted earnings per share.  Perficient believes that excluding these expenses from its non-GAAP financial measures is useful to investors because these are expenses associated with each transaction, and are inconsistent in amount and frequency causing comparison of current and historical financial results to be difficult.

Adjustments to Fair Value of Contingent Consideration

Perficient is required to remeasure its contingent consideration liability related to acquisitions each reporting period until the contingency is settled.  Any changes in fair value are recognized in earnings.  Management excludes these items for the purposes of calculating adjusted net income and adjusted earnings per share.  Perficient believes that excluding these adjustments from its non-GAAP financial measures is useful to investors because they are related to acquisitions, and are inconsistent in amount and frequency from period to period.

Stock-Based Compensation

Perficient incurs stock-based compensation expense under Financial Accounting Standards Board Accounting Standards Codification Topic 718, Compensation – Stock Compensation.  Perficient excludes this item for the purposes of calculating EBITDAS, adjusted net income, and adjusted earnings per share because it is a non-cash expense, which Perficient believes is not reflective of its business performance. The nature of stock-based compensation expense also makes it very difficult to estimate prospectively, since the expense will vary with changes in the stock price and market conditions at the time of new grants, varying valuation methodologies, subjective assumptions, and different award types, making the comparison of current results with forward looking guidance potentially difficult for investors to interpret. The tax effects of stock-based compensation expense may also vary significantly from period to period, without any change in underlying operational performance, thereby obscuring the underlying profitability of operations relative to prior periods.  Perficient believes that non-GAAP measures of profitability, which exclude stock-based compensation are widely used by analysts and investors.
