All subsequent forward-looking statements attributable to Merit or persons acting on its behalf are expressly qualified in their entirety by these cautionary statements. Actual results will likely differ, and may differ materially, from anticipated results. Financial estimates are subject to change and are not intended to be relied upon as predictions of future operating results. Those estimates and all other forward-looking statements included in this document are made only as of the date of this document, and except as otherwise required by applicable law, Merit assumes no obligation to update or disclose revisions to estimates and all other forward-looking statements. 2

3 NON-GAAP FINANCIAL MEASURES Although Merit’s financial statements are prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”), Merit’s management believes that certain non-GAAP financial measures provide investors with useful information regarding the underlying business trends and performance of Merit’s ongoing operations and can be useful for period-over-period comparisons of such operations. Certain financial measures included in this presentation, or which may be referenced in management’s discussion of Merit’s historical and future operations and financial results, have not been calculated in accordance with GAAP, and, therefore, are referenced as non-GAAP financial measures. Readers should consider non-GAAP measures used in this presentation in addition to, not as a substitute for, financial reporting measures prepared in accordance with GAAP. These non-GAAP financial measures generally exclude some, but not all, items that may affect Merit's net income. In addition, they are subject to inherent limitations as they reflect the exercise of judgment by management about which items are excluded. Additionally, non-GAAP financial measures used in this presentation may not be comparable with similarly titled measures of other companies. Merit urges readers to review the reconciliations of its non-GAAP financial measures to the comparable GAAP financial measures, and not to rely on any single financial measure to evaluate Merit’s business or results of operations. Please refer to “Notes to Non-GAAP Financial Measures” at the end of these materials for more information.

9 2025 Financial Guidance Merit does not provide guidance for GAAP reported financial measures (other than revenue) or a reconciliation of forward-looking non-GAAP financial measures to the most directly comparable GAAP reported financial measures (other than revenue) because Merit is unable to predict with reasonable certainty the financial impact of various items which could impact Merit’s future financial results, such as expenses related to acquisitions or other extraordinary transactions, non-cash expenses related to amortization or write-off of previously acquired tangible and intangible assets, certain employee termination benefits, performance-based stock compensation expenses, expenses resulting from non-ordinary course litigation or administrative proceedings and resulting settlements, governmental proceedings, and changes in governmental or industry regulations. These items are uncertain, depend on various factors, and could have a material impact on GAAP reported results for the guidance period. For the same reasons, Merit is unable to address the significance of the unavailable information, which could be material to future results. Specifically, Merit is not, without unreasonable effort, able to reliably predict the impact of these items and Merit believes inclusion of a reconciliation of these forward-looking non-GAAP measures to their GAAP counterparts could be confusing to investors or cause undue reliance. Merit’s financial guidance for the year ending December 31, 2025, is subject to risks and uncertainties identified in this release and Merit’s filings with the U.S. Securities and Exchange Commission (the “SEC”). *Percentage figures approximated; figures may not foot due to rounding **Merit’s non-GAAP earnings per share reflect the dilutive impact of its Convertible Notes calculated using the if-converted method of approximately $.02 and $0.11 for the years ending December 31, 2024 and 2025 respectively. Any offsetting impacts of the capped call associated with the Convertible Notes are not considered.

10 Appendix

11 Notes to Non-GAAP Financial Measures For additional details, please see the accompanying press release and forward-looking statement disclosure. These presentation materials and associated commentary from Merit’s management, as well as the press release issued today, use non-GAAP financial measures, including: • constant currency revenue; • constant currency revenue, organic; • non-GAAP gross profit and margin; • non-GAAP operating income and margin; • non-GAAP net income; • non-GAAP earnings per share; and • free cash flow. Merit’s management team uses these non-GAAP financial measures to evaluate Merit’s profitability and efficiency, to compare operating and financial results to prior periods, to evaluate changes in the results of its operating segments, and to measure and allocate financial resources internally. However, Merit’s management does not consider such non-GAAP measures in isolation or as an alternative to measures determined in accordance with GAAP. Readers should consider non-GAAP measures used in this release in addition to, not as a substitute for, financial reporting measures prepared in accordance with GAAP. These non-GAAP financial measures generally exclude some, but not all, items that may affect Merit’s net income. In addition, they are subject to inherent limitations as they reflect the exercise of judgment by management about which items are excluded. Merit believes it is useful to exclude such items in the calculation of non-GAAP gross profit and margin, non-GAAP operating income and margin, non-GAAP net income, and non-GAAP earnings per share (in each case, as further illustrated in the reconciliation tables below) because such amounts in any specific period may not directly correlate to the underlying performance of Merit’s business operations and can vary significantly between periods as a result of factors such as acquisition or other extraordinary transactions, non-cash expenses related to amortization or write-off of previously acquired tangible and intangible assets, certain employee termination benefits, expenses resulting from non-ordinary course litigation or administrative proceedings and resulting settlements, governmental proceedings or changes in tax or industry regulations, gains or losses on disposal of certain assets, and debt issuance costs. Merit may incur similar types of expenses in the future, and the non-GAAP financial information included in this release should not be viewed as a statement or indication that these types of expenses will not recur. Additionally, the non-GAAP financial measures used in this release may not be comparable with similarly titled measures of other companies. Merit urges readers to review the reconciliations of its non-GAAP financial measures to their most directly comparable GAAP financial measures included herein, and not to rely on any single financial measure to evaluate Merit’s business or results of operations.

12 Notes to Non-GAAP Financial Measures (cont.) Constant Currency Revenue Merit’s constant currency revenue is prepared by converting the current-period reported revenue of subsidiaries whose functional currency is a currency other than the U.S. dollar at the applicable foreign exchange rates in effect during the comparable prior-year period and adjusting for the effects of hedging transactions on reported revenue, which are recorded in the U.S. dollar. The constant currency revenue adjustments of $2.2 million and $7.2 million to reported revenue for the three and twelve-month periods ended December 31, 2024, respectively, were calculated using the applicable average foreign exchange rates for the three and twelve-month periods ended December 31, 2023. Constant Currency Revenue, Organic Merit’s constant currency revenue, organic, is defined, with respect to prior fiscal year periods, as GAAP revenue. With respect to current fiscal year periods, constant currency revenue, organic, is defined as constant currency revenue (as defined above), less revenue from certain acquisitions. For the three-month period ended December 31, 2024, Merit’s constant currency revenue, organic, excludes revenues attributable to (i) the assets acquired from Cook Medical Holdings, LLC (“Cook Medical”) in November 2024 and (ii) the assets acquired from EndoGastric Solutions, Inc. (“EGS”) in July 2024. For the twelve-month period ended December 31, 2024, Merit’s constant currency revenue, organic, excludes revenues attributable to (a) the assets acquired from EGS in July 2024, (b) the assets acquired from Cook Medical in November 2024 and (c) the assets acquired from AngioDynamics, Inc. in June 2023. Non-GAAP Gross Profit and Margin Non-GAAP gross profit is calculated by reducing GAAP cost of sales by amounts recorded for amortization of intangible assets, corporate restructuring charges, and inventory mark-up related to acquisitions. Non-GAAP gross margin is calculated by dividing non-GAAP gross profit by reported net sales. Non-GAAP Operating Income and Margin Non-GAAP operating income is calculated by adjusting GAAP operating income for certain items which are deemed by Merit’s management to be outside of core operations and vary in amount and frequency among periods, such as expenses related to acquisitions or other extraordinary transactions, non-cash expenses related to amortization or write-off of previously acquired tangible and intangible assets, certain employee termination benefits, performance-based stock compensation expenses, expenses resulting from non-ordinary course litigation or administrative proceedings and resulting settlements, governmental proceedings, and changes in governmental or industry regulations, as well as other items referenced in the tables below. Non-GAAP operating margin is calculated by dividing non-GAAP operating income by reported net sales.

13 Notes to Non-GAAP Financial Measures (cont.) Non-GAAP Net Income Non-GAAP net income is calculated by adjusting GAAP net income for the items set forth in the definition of non-GAAP operating income above, as well as for expenses related to debt issuance costs, gains or losses on disposal of certain assets and other items set forth in the tables below. Non-GAAP EPS Non-GAAP EPS is defined as non-GAAP net income divided by the diluted shares outstanding for the corresponding period. Free Cash Flow Free cash flow is defined as cash flow from operations calculated in accordance with GAAP, less capital expenditures for property and equipment calculated in accordance with GAAP, as set forth in the consolidated statement of cash flows. Other Non-GAAP Financial Measure Reconciliation The following tables set forth supplemental financial data and corresponding reconciliations of non-GAAP financial measures to Merit’s corresponding financial measures prepared in accordance with GAAP, in each case, for the three and twelve-month periods ended December 31, 2024 and 2023. The non-GAAP income adjustments referenced in the following tables do not reflect non-performance-based stock compensation expense of approximately $3.7 million and $3.5 million for the three-month periods ended December 31, 2024 and 2023, respectively and $13.3 million and $12.7 million for the twelve-month periods ended December 31, 2024 and 2023, respectively.

17 Footnotes to Reconciliations of GAAP Net Income to Non-GAAP Net Income and GAAP Operating Income to Non-GAAP Operating Income a) Beginning in the second quarter of 2024, consulting expenses associated with initiatives conducted under Merit’s Foundations for Growth Program (“FFG Program”) are not adjusted as part of its non-GAAP financial measures. As a result, Merit’s non-GAAP financial measures for prior periods have been recast for comparability. For the three-month period ended December 31, 2023, our non-GAAP financial measures have been updated to no longer adjust $5.3 million for consulting fees under its FFG Program and the related income tax effect. For the twelve-month periods ended December 31, 2024 and 2023, Merit’s non-GAAP financial measures have been updated to no longer adjust $1.0 million and $12.3 million, respectively, for consulting fees under its FFG Program and the related income tax effects.
