The reader is cautioned not to put undue reliance on these forward-looking statements, as these statements are subject to numerous factors and uncertainties outside of the Company’s control that can make such statements untrue, including, but not limited to, the impact of inflation, rising interest rates or a recession; the adequacy of the Company’s liquidity to pursue its business objectives; the Company’s ability to obtain reimbursement from third-party payers for its products; adverse economic conditions or intense competition; price increases for supplies and components; wage and component price inflation; loss of a key supplier; entry of new competitors and products; compliance with and changes in federal, state and local government regulation; loss or retirement of key executives, including prior to identifying a successor; technological obsolescence of the Company’s products; technical problems with the Company’s research and products; the Company’s ability to expand its business through strategic acquisitions; the Company’s ability to integrate acquisitions and related businesses; the impacts of the COVID-19 pandemic on the Company’s business, financial condition and results of operations, and the Company’s inability to mitigate such impacts; the effects of current and future U.S. and foreign trade policy and tariff actions; or the inability to carry out research, development and commercialization plans.

Use of Non-GAAP Financial Measures

This press release includes the non-GAAP financial measures of Adjusted EBITDA, non-GAAP gross profit, non-GAAP gross margin, non-GAAP operating income (loss), and non-GAAP net income (loss), which differ from financial measures calculated in accordance with U.S. generally accepted accounting principles (“GAAP”).

Adjusted EBITDA in this release represents net income or loss, plus interest expense, net, or less interest income, net, less income tax benefit or plus income tax expense, plus depreciation and amortization, plus stock-based compensation expense, plus or minus the change in fair value of earn-out, and plus litigation defense costs. Non-GAAP gross profit in this release represents gross profit plus non-cash intangible amortization expense. Non-GAAP gross margin in this release represents non-GAAP gross profit divided by revenue. Non-GAAP operating income (loss) in this release represents operating income (loss) adjusted for non-cash intangible amortization expense, change in fair value of earn-out and litigation defense costs. Non-GAAP net income (loss) represents net income (loss) adjusted for non-cash intangible amortization expense, change in fair value of earn-out and litigation defense costs, and adjusted for the income tax effect on reconciling items. Reconciliations of these non-GAAP financial measures to their most directly comparable GAAP measures are included in this press release.

These non-GAAP financial measures are presented because the Company believes they are useful indicators of its operating performance. Management uses these measures principally as measures of the Company’s operating performance and for planning purposes, including the preparation of the Company’s annual operating plan and financial projections. The Company believes these measures are useful to investors as supplemental information and because they are frequently used by analysts, investors and other interested parties to evaluate companies in its industry. The Company also believes these non-GAAP financial measures are useful to its management and investors as a measure of comparative operating performance from period to period. In addition, Adjusted EBITDA is used as a performance metric in the Company’s compensation program.

The non-GAAP financial measures presented in this release should not be considered as an alternative to, or superior to, their respective GAAP financial measures, as measures of financial performance or cash flows from operations as a measure of liquidity, or any other performance measure derived in accordance with GAAP, and they should not be construed to imply that the Company’s future results will be unaffected by unusual or non-recurring items. In addition, Adjusted EBITDA is not intended to be a measure of free cash flow for management’s discretionary use, as it does not reflect certain cash requirements such as tax payments, debt service requirements, capital expenditures and certain other cash costs that may recur in the future. Adjusted EBITDA contains certain other limitations, including the failure to reflect our cash expenditures, cash requirements for working capital needs and cash costs to replace assets being depreciated and amortized. In evaluating non-GAAP financial measures, you should be aware that in the future the Company may incur expenses that are the same as or similar to some of the adjustments in this presentation. The Company’s presentation of non-GAAP financial measures should not be construed to imply that its future results will be unaffected by any such adjustments. Management compensates for these limitations by primarily relying on the Company’s GAAP results in addition to using non-GAAP financial measures on a supplemental basis. The Company’s definition of these non-GAAP financial

measures is not necessarily comparable to other similarly titled captions of other companies due to different methods of calculation.
