About Non-GAAP Financial Information

This news release includes non-GAAP financial measures. For a description of these non-GAAP financial measures, including the reasons management uses each measure, and reconciliations of these non-GAAP financial measures to the most directly comparable financial measures prepared in accordance with Generally Accepted Accounting Principles (“GAAP”), please see the section entitled “About Non-GAAP Financial Measures” and the accompanying tables entitled “Reconciliation of GAAP to Non-GAAP Measures.”

About Non-GAAP Financial Measures

Perficient provides non-GAAP financial measures for EBITDAS (earnings before interest, income taxes, depreciation, amortization, stock compensation, acquisition costs and adjustment to fair value of contingent consideration), 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 restricted stock awards, the amortization of intangible assets, amortization of debt discounts and issuance costs related to convertible senior notes, acquisition costs, adjustments to the fair value of contingent consideration, net other income and expense, the impact of other infrequent or unusual transactions, 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

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 merger and acquisition-related activities 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.

Adjustment 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 EBITDAS, 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.

Amortization of Debt Discount and Debt Issuance Costs

On September 11, 2018, Perficient issued $143.8 million aggregate principal amount of 2.375% Convertible Senior Notes due 2023 (the “Notes”) in a private placement to qualified institutional purchasers. In accordance with accounting for debt with conversions and other options, the company bifurcated the principal amount of the Notes into liability and equity components. The resulting debt discount is being amortized to interest expense over the period from the issuance date through the contractual maturity date of September 15, 2023. Issuance costs related to the Notes were allocated pro rata based on the relative fair values of the liability and equity components. Issuance costs attributable to the liability component of the Notes, in addition to issuance costs related to Perficient’s credit agreement, are being amortized to interest expense over their respective terms. Perficient believes that excluding these non-cash expenses from its non-GAAP financial measures is useful to investors because the expenses are not reflective of the company’s business performance.

Write-off of Unamortized Credit Facility Fees

Perficient entered into a new credit agreement during the second quarter of 2017. In connection with the new agreement, Perficient wrote off unamortized credit facility fees associated with the former credit agreement. Perficient believes that excluding this non-cash write-off from its non-GAAP financial measures is useful to investors because the expense is infrequent and not reflective of the company’s business performance.

Stock Compensation

Perficient incurs stock-based compensation expense under Financial Accounting Standards Board Accounting Standards Codification Topic 718, Compensation - Stock Compensation. Perficient excludes stock-based compensation expense and the related tax effects for the purposes of calculating EBITDAS, adjusted net income, and adjusted earnings per share because stock-based compensation 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.

Tax Impact of China Repatriation

During the second quarter of 2017, Perficient determined that as a result of changes in the business and macroeconomic environment, the foreign earnings of the company’s Chinese subsidiary were no longer permanently reinvested and may repatriate available earnings from time to time. A provision for the expected taxes on repatriation of these earnings was recorded in the amount of $2.5 million during the three and six months ended June 30, 2017. Perficient believes that excluding this incremental tax expense from its non-GAAP financial measures is useful to investors because this expense is infrequent and can cause comparison of current and historical financial results to be difficult.
