Non-GAAP Income Tax Expense

Starting April 1, 2021, the Company changed the calculation of its non-GAAP provision for income taxes in accordance with the SEC guidance of non-GAAP financial measures and has applied such change to all periods presented. The Company’s current and deferred income tax expense is commensurate with the non-GAAP measure of profitability using a non-GAAP tax rate of 20% for the three and six months ended June 30, 2021 and 2020. The Company uses annual projected tax rate in its computation of the non-GAAP income tax provision, and excludes the direct impact of stock-based compensation, intangible amortization expenses and acquisition related expenses. The projected rate considers other factors such as our current operating structure, existing tax positions in various jurisdictions, and key legislation in major jurisdictions where we operate.

The change will not affect the company’s non-GAAP income before income taxes, actual cash tax payments, or cash flows, but will result in higher non-GAAP provision for income taxes. The Company, however, does not expect to pay substantial taxes on a GAAP basis in the U.S. and certain other foreign jurisdictions for the foreseeable future due to its net operating loss carryforward balances.

Computational Guidance on Earnings Per Share Estimates

Accounting principles require that EPS be computed based on the weighted average shares outstanding (“basic”), and also assuming the issuance of potentially issuable shares (such as those subject to stock options, convertible notes, etc.) if those potentially issuable shares would reduce EPS (“diluted”).

The number of shares related to options and similar instruments included in diluted EPS is based on the “Treasury Stock Method” prescribed in Financial Accounting Standards Board (“FASB”) ASC Topic 260, Earnings Per Share (“FASB ASC Topic 260”). This method assumes a theoretical repurchase of shares using the proceeds of the respective stock option exercise at a price equal to the issuer’s average stock price during the related earnings period. Accordingly, the number of shares includable in the calculation of diluted EPS in respect of stock options and similar instruments is dependent on this average stock price and will increase as the average stock price increases.

Starting January 1, 2021, the number of shares includable in the calculation of diluted EPS in respect of convertible senior notes is based on the “If Converted” method prescribed in FASB ASC Topic 260. This method assumes the conversion or exchange of these securities for shares of common stock. In determining if convertible securities are dilutive, the interest savings (net of tax) subsequent to an assumed conversion are added back to net earnings. The shares related to a convertible security are included in diluted EPS only if EPS as otherwise calculated is greater than the interest savings, net of tax, divided by the shares issuable upon exercise or conversion of the instrument. Accordingly, the calculation of diluted EPS for these instruments is dependent on the level of net earnings.

Use of Non-GAAP Financial Information

This press release contains financial measures that are not calculated in accordance with U.S. generally accepted accounting principles (GAAP). Our management evaluates the Company’s results and makes operating decisions using various GAAP and non-GAAP measures. In addition to our GAAP results, we also consider non-GAAP gross margin, non-GAAP gross margin for products and for services, non-GAAP net income/(loss), non-GAAP diluted income/(loss) per share, non-GAAP operating expenses, non-GAAP other expense, net and non-GAAP provision for (benefit from) income taxes. We also present Adjusted EBITDA, a non-GAAP measure that we reconcile to net income/(loss). These non-GAAP measures should not be considered as a substitute for the corresponding financial measure derived in accordance with GAAP. We present the non-GAAP measures because we consider them to be important supplemental information for our investors for analyzing our performance, core operating results and trends. Investors are encouraged to review the reconciliation of non-GAAP financial measures to their most directly comparable GAAP measures included with this press release.

Our non-GAAP gross margins, non-GAAP net income/(loss), non-GAAP diluted income/(loss) per share, non-GAAP operating expenses, non-GAAP other expense, net, non-GAAP provision for (benefit from) income taxes, and Adjusted EBITDA are exclusive of certain items to facilitate management’s review of the comparability of our core operating results on a period-to-period basis because such items are not related to our ongoing core operating results as viewed by management. We define our “core operating results” as those revenues recorded in a particular period and the expenses incurred within that period that directly drive operating income in that period. Management uses these non-GAAP financial measures in making operating decisions because, in addition to meaningful supplemental information regarding operating performance, the measures give us a better understanding of how we should invest in research and development, fund infrastructure growth and evaluate the effectiveness of marketing strategies. In calculating the above non-GAAP results, management specifically adjusted for the following excluded items:

a) Stock-based compensation expense impact. We recognize equity plan-related compensation expenses, which represent the fair value of all share-based payments to employees, including grants of employee stock options and restricted stock units as non-GAAP adjustments in each period.

b) Amortization of acquired intangibles. We acquired certain companies in 2021, 2020, 2016, and 2014, and booked intangible assets related to these acquisitions. The amortization of these acquired intangible assets is excluded from non-GAAP net income because it is not related to ongoing controllable management decisions and because it is non-cash in nature.

c) Acquisition related expenses. In addition to the amortization of acquired intangibles mentioned above, we also adjust for certain acquisition-related expenses that we may incur including (i) professional service fees and (ii) transition costs. Professional service fees include third party costs related to the acquisition, such as due diligence costs, accounting fees, legal fees, valuation services and commissions, if any. Transition costs include retention payments and other transitional employee costs treated as compensation expense as well as the change in the fair value of contingent consideration payments payable to the selling shareholders. We consider such costs and adjustments as highly variable in amount and frequency, being significantly impacted by the timing and size of any acquisitions. By excluding acquisition-related costs and adjustments from our non-GAAP measures, management can better focus on the organic continuing operations of our baseline and acquired businesses.

d) Income tax effects. Starting April 1, 2021, we changed the calculation of our non-GAAP provision for income taxes in accordance with the SEC guidance of non-GAAP financial measures. The Company’s current and deferred income tax expense is commensurate with the non-GAAP measure of profitability using a non-GAAP tax rate of 20% for the three and six months ended June 30, 2021 and 2020. We use the annual projected tax rate in computation of the non-GAAP income tax provision, and exclude the direct impact of stock-based compensation, intangible amortization expenses and acquisition related expenses. The projected rate considers other factors such as our current operating structure, existing tax positions in various jurisdictions, and key legislation in major jurisdictions where we operate.

Management adjusts for the above items because management believes that, in general, these items possess one or more of the following characteristics: their magnitude and timing are largely outside of the Company’s control; they are unrelated to the ongoing operation of the business in the ordinary course; they are unusual and we do not expect them to occur in the ordinary course of business; or they are non-operational, or non-cash expenses involving stock award grants.

We believe that the presentation of these non-GAAP financial measures is warranted for several reasons:

a) Such non-GAAP financial measures provide an additional analytical tool for understanding our financial performance by excluding the impact of items which may obscure trends in the core operating results of the business;

b) These non-GAAP financial measures facilitate comparisons to the operating results of other companies commonly compared to us, which use similar financial measures to supplement their GAAP results, thus enhancing the perspective of investors who wish to utilize such comparisons in their analysis of our performance; and

c) These non-GAAP financial measures are employed by our management in their own evaluation of performance and are utilized in financial and operational decision-making processes, such as budget planning and forecasting.

Set forth below are additional reasons why share-based compensation expense is excluded from our non-GAAP financial measures:

a) While share-based compensation constitutes one of our ongoing and recurring expenses, it is not an expense that requires cash settlement by us. We therefore exclude these charges for purposes of evaluating core operating results. Thus, our non-GAAP measurements are presented exclusive of stock-based compensation expense to assist management and investors in evaluating our core operating results.

b) We present share-based payment compensation expense in our reconciliation of non-GAAP financial measures on a pre-tax basis because the exact tax differences related to the timing and deductibility of share-based compensation are dependent upon the trading price of our common stock and the timing and exercise by employees of their stock options. As a result of these timing and market uncertainties, the tax effect related to share-based compensation expense would be inconsistent in amount and frequency and is therefore excluded from our non-GAAP results.

As stated above, we present non-GAAP financial measures because we consider them to be important supplemental measures of performance. However, non-GAAP financial measures have limitations as an analytical tool and should not be considered in isolation or as a substitute for our GAAP results. In the future, we expect to incur expenses similar to certain of the non-GAAP adjustments described above and expect to continue reporting non-GAAP financial measures excluding such items. Some of the limitations in relying on non-GAAP financial measures are:

• Our stock options, restricted stock units, performance based restricted stock units, and stock purchase plans are important components of incentive compensation arrangements and will be reflected as expenses in our GAAP results for the foreseeable future; and
• Other companies may calculate non-GAAP financial measures differently than us, limiting their usefulness as a comparative measure.

Pursuant to the requirements of SEC Regulation G, a detailed reconciliation between our non-GAAP and GAAP financial results is set forth in the financial tables referred to above, and linked to, this press release. Investors are advised to carefully review and consider this information strictly as a supplement to the GAAP results for the respective periods.

(a) This adjustment reflects the accounting impact of the quarterly valuation reassessment of contingent consideration resulting from the 2020 acquisition of $(1.7) million and $(1.3) million for the three and six months ended June 30, 2021, respectively and the induced conversion expense from repurchasing our 2023 Notes of $2.1 million for the six months ended June 30, 2021.

(b) Starting April 1, 2021, the Company changed the calculation of its non-GAAP provision for income taxes in accordance with the SEC guidance of non-GAAP financial measures. The Company’s current and deferred income tax expense is commensurate with the non-GAAP measure of profitability using a non-GAAP tax rate of 20% for the three and six months ended June 30, 2021 and 2020. The Company uses annual projected tax rate in its computation of the non-GAAP income tax provision, and excludes the direct impact of stock-based compensation, intangible amortization expenses and acquisition related expenses.
