Use of Non-GAAP Financial Measures

To supplement our unaudited consolidated financial statements presented on a GAAP basis, we disclose certain non-GAAP financial measures, including adjusted net income (loss), adjusted net income (loss) attributable to Boston Scientific common stockholders and adjusted net income (loss) per share (EPS) that exclude certain charges (credits); operational net sales, which exclude the impact of foreign currency fluctuations; and organic net sales, which exclude the impact of foreign currency fluctuations as well as the impact of acquisitions and divestitures with less than a full period of comparable net sales. These non-GAAP financial measures are not in accordance with generally accepted accounting principles in the United States and should not be considered in isolation from or as a replacement for the most directly comparable GAAP financial measures. Further, other companies may calculate these non-GAAP financial measures differently than we do, which may limit the usefulness of those measures for comparative purposes.

To calculate adjusted net income (loss), adjusted net income (loss) attributable to Boston Scientific common stockholders and adjusted net income (loss) per share, we exclude certain charges (credits) from GAAP net income and GAAP net income attributable to Boston Scientific common stockholders, which include amortization expense, goodwill and intangible asset impairment charges, acquisition/divestiture-related net charges (credits), investment portfolio gains and losses, restructuring and restructuring-related net charges (credits), certain litigation-related net charges (credits), EU MDR implementation costs, debt extinguishment charges, deferred tax expenses (benefits) and discrete tax items. Amounts are presented after-tax using the company's effective tax rate, unless the amount is a significant unusual or infrequently occurring item in accordance with Financial Accounting Standards Board Accounting Standards Codification Topic 740-270-30, “General Methodology and Use of Estimated Annual Effective Tax Rate.” Please refer to Part II, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations in our most recent Annual Report filed on Form 10-K filed with the Securities and Exchange Commission or Part I, Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations in any Quarterly Report on Form 10-Q that we have filed or will file thereafter for an explanation of each of these adjustments and the reasons for excluding each item.

The GAAP financial measures most directly comparable to adjusted net income (loss), adjusted net income (loss) attributable to Boston Scientific common stockholders and adjusted net income (loss) per share are GAAP net income (loss), GAAP net income (loss) attributable to Boston Scientific common stockholders and GAAP net income (loss) per common share – diluted, respectively.

To calculate operational net sales growth rates, which exclude the impact of foreign currency fluctuations, we convert actual net sales from local currency to U.S. dollars using constant foreign currency exchange rates in the current and prior periods. To calculate organic net sales growth rates, we also remove the impact of acquisitions and divestitures with less than a full period of comparable net sales. The GAAP financial measure most directly comparable to operational net sales and organic net sales is net sales on a GAAP basis.

Reconciliations of each of these non-GAAP financial measures to the corresponding GAAP financial measure are included in the accompanying schedules.

Management uses these supplemental non-GAAP financial measures to evaluate performance period over period, to analyze the underlying trends in our business, to assess our performance relative to our competitors and to establish operational goals and forecasts that are used in allocating resources. In addition, management uses these non-GAAP financial measures to


further its understanding of the performance of our operating segments. The adjustments excluded from our non-GAAP financial measures are consistent with those excluded from our operating segments’ measures of net sales and profit or loss. These adjustments are excluded from the segment measures reported to our chief operating decision maker that are used to make operating decisions and assess performance.

We believe that presenting adjusted net income (loss), adjusted net income (loss) attributable to Boston Scientific common stockholders, adjusted net income (loss) per share, operational net sales growth rates and organic net sales growth rates, in addition to the corresponding GAAP financial measures, provides investors greater transparency to the information used by management for its operational decision-making and allows investors to see our results “through the eyes” of management. We further believe that providing this information assists our investors in understanding our operating performance and the methodology used by management to evaluate and measure such performance.
