Key Operating Metrics And Non-GAAP

Financial Measures

To supplement our financial information presented in accordance with generally accepted accounting principles in the United States (GAAP), from period to period, we consider and present certain operating and financial measures that we consider key metrics or are not prepared in accordance with GAAP, including Gross Payment Volume (GPV), Adjusted EBITDA, Adjusted EBITDA margin, Adjusted Net Income (Loss), Adjusted Net Income (Loss) Per Share (Adjusted EPS), Adjusted Diluted Net Income (Loss) Per Share (Adjusted Diluted EPS), Adjusted Operating Income (Loss), Adjusted Operating Income (Loss) margin, Free Cash Flow, Non-GAAP Cash Flow, constant currency, and non-GAAP operating expenses. We believe these metrics and measures are useful to facilitate period-to-period comparisons of our business and to facilitate comparisons of our performance to that of other payments solution providers. GPV includes Square GPV and Cash App Business GPV. Square GPV is defined as the total dollar amount of all card and bank payments processed by sellers using Square, net of refunds. Cash App Business GPV comprises Cash App activity related to peer-to-peer transactions received by business accounts and peer-to-peer payments sent from a credit card. GPV does not include transactions from our BNPL products.

Adjusted Net Income (Loss), Adjusted Net Income (Loss) Per Share (Adjusted EPS), and Adjusted Diluted Net Income (Loss) Per Share (Adjusted Diluted EPS) are non-GAAP financial measures that represent our net income (loss) and net income (loss) per share, adjusted to eliminate the effect of restructuring share-based compensation expense, contingencies, restructuring, and other charges; goodwill and intangible asset impairment; amortization of intangible assets; amortization of debt discount and issuance costs; gain or loss on revaluation of equity investments; remeasurement gain or loss on revaluation of bitcoin investment; the gain or loss on the disposal of property and equipment; acquired deferred revenue and cost adjustments; the discrete benefits from the release of valuation allowances on our deferred tax assets; and the tax effect of non-GAAP net income adjustments, as applicable. Additionally, for purposes of calculating Adjusted Diluted EPS, we add back cash interest expense on convertible senior notes, as if converted at the beginning of the period, if the impact is dilutive. To calculate Adjusted Diluted EPS, we adjust the weighted-average number of shares of common stock outstanding for the dilutive effect of all potential shares of common stock. In periods when we recorded an Adjusted Net Loss, the diluted Adjusted EPS is the same as basic Adjusted EPS because the effects of potentially dilutive items were anti-dilutive given the Adjusted Net Loss position.

Adjusted EBITDA and Adjusted EBITDA margin are non-GAAP financial measures that represent our net income (loss), adjusted to exclude share-based compensation expense; restructuring share-based compensation expense; depreciation and amortization; contingencies,

restructuring, and other charges; interest income and expense; remeasurement gain or loss on bitcoin investment; other income and expense; provision for (benefit from) income taxes; gain or loss on disposal of property and equipment; and acquired deferred revenue and cost adjustment, as applicable. Adjusted EBITDA margin is calculated as Adjusted EBITDA divided by gross profit.

Adjusted Operating Income (Loss) is a non-GAAP financial measure that represents our operating income (loss), adjusted to eliminate the effect of amortization of acquired technology assets; contingencies, restructuring, and other charges; restructuring share-based compensation expenses; goodwill and intangible asset impairment and amortization of customer and other acquired intangible assets. Adjusted Operating Income (Loss) margin is calculated as Adjusted Operating Income (Loss) divided by gross profit.

We also exclude from these measures certain acquisition-related and integration costs associated with business combinations, and various other costs that are not reflective of our core operating performance. We exclude amortization of intangible assets arising from business combinations from Adjusted Net Income (Loss), Adjusted EPS, Adjusted Diluted EPS, Adjusted Operating Income (Loss), and Adjusted Operating Income (Loss) Margin because the amount of such expenses in any specific period may not directly correlate to the underlying performance of our ongoing business operations. Acquisition-related costs include amounts paid to redeem acquirees’ unvested stock-based compensation awards; charges associated with holdback liabilities; and legal, accounting, and due diligence costs. Integration costs include advisory and other professional services or consulting fees necessary to integrate acquired businesses. Other costs that are not reflective of our core business operating expenses may include contingencies, restructuring, and other charges; impairment charges; restructuring share-based compensation expense; and certain litigation and regulatory charges. For Adjusted Net Income (Loss), Adjusted EPS, and Adjusted Diluted EPS we also add back the impact of the acquired deferred revenue and deferred cost adjustment, which was written down to fair value in purchase accounting, and adjust for the tax effect of the non-GAAP net income adjustments.

Non-GAAP Cash Flow is a non-GAAP financial measure that represents our net cash provided by operating activities adjusted for changes in settlements receivable; changes in customers payable; changes in settlements payable; the purchase of property and equipment; payments for originations of consumer receivables; proceeds from principal repayments and sales of consumer receivables; purchases and originations of loans originally classified as held for investment; proceeds from repayments of loans originally classified as held for investment; proceeds from warehouse facilities borrowings; repayments of warehouse facilities borrowings; and sales, and principal payments, and forgiveness of PPP loans. We present Non-GAAP Cash Flow because we use it to understand the cash generated by our business and make strategic decisions related to our balance sheet, and because we are focused on growing our Non-GAAP Cash Flow generation over time. It is not intended to represent amounts available for discretionary purposes. Constant currency growth is calculated by assuming international results in a given period and the comparative prior period are translated from local currencies to the U.S. dollar at rates consistent with the monthly average rates in the comparative prior period. We discuss growth on a constant currency basis because a portion of our business operates in markets outside the U.S. and is subject to changes in foreign exchange rates. Non-GAAP operating expenses is a non-GAAP financial measure that represents operating expenses adjusted to remove the impact of restructuring share-based compensation; amortization of customer and other acquired intangible assets; acquisition-related and integration costs; contingencies, restructuring, and other charges; and goodwill and intangible asset impairment. We have included Adjusted EBITDA, Adjusted EBITDA margin, Adjusted Operating Income (Loss), Adjusted Operating Income (Loss) margin,

Adjusted Net Income (Loss), Adjusted EPS, Adjusted Diluted EPS, and non-GAAP operating expenses because they are key measures used by our management to evaluate our operating performance, generate future operating plans, and make strategic decisions, including those relating to operating expenses and the allocation of internal resources. Accordingly, we believe that Adjusted EBITDA, Adjusted EBITDA margin, Adjusted Operating Income (Loss), Adjusted Operating Income (Loss) margin, Adjusted Net Income, Adjusted EPS, Adjusted Diluted EPS, and non-GAAP operating expenses provide useful information to investors and others in understanding and evaluating our operating results in the same manner as our management and board of directors. In addition, they provide useful measures for period-to-period comparisons of our business, as they remove the effect of certain non-cash items and certain variable charges that do not vary with our operations. Adjusted EBITDA, Adjusted EBITDA margin, Adjusted Net Income (Loss), Adjusted Operating Income (Loss), Adjusted Operating Income (Loss) margin, Adjusted EPS, Adjusted Diluted EPS, and non-GAAP operating expenses, as well as other measures defined in the shareholder letter, have limitations as financial measures, should be considered as supplemental in nature, and are not meant as substitutes for the related financial information prepared in accordance with GAAP. We believe that the aforementioned metrics and measures provide useful information about our operating results, enhance the overall understanding of our past performance and future prospects, and provide useful measures for period-to-period comparisons of our business, as they remove the effect of certain variable amounts, or they remove amounts that were not repeated across periods and therefore make comparisons more difficult. Our management uses these measures to evaluate our operating performance, generate future operating plans, and make strategic decisions, including those relating to operating expenses and the allocation of internal resources. These non-GAAP financial measures should not be considered in isolation from, or as a substitute for, financial information prepared in accordance with GAAP. These non-GAAP financial measures are not based on any standardized methodology prescribed by GAAP. Other companies, including companies in our industry, may calculate the non-GAAP financial measures differently or not at all, which reduces their usefulness as comparative measures.
