Note on Non-GAAP Financial Measures

This press release includes non-GAAP financial measures that differ from financial measures calculated in accordance with U.S. generally accepted accounting principles ( GAAP ). These non-GAAP financial measures may not be comparable to similar measures reported by other companies and should be considered in addition to, and not as a substitute for, or superior to, other measures prepared in accordance with GAAP.

Net sales change information for the three- and nine-month periods ended September 30, 2023 is presented on a GAAP (reported) basis and on a constant currency basis. Constant currency percentage changes exclude the effects of foreign currency exchange rates. They are calculated by translating current and prior-period sales at the same predetermined exchange rate. The translated results are then used to determine year-over-year percentage increases or decreases.

Net earnings and diluted earnings per share for the three- and nine-month periods ended September 30, 2023, net earnings and diluted earnings per share for the three-month period ended September 30, 2022, and net earnings and diluted earnings per share from continuing operations for the nine-month period ended September 30, 2022 are presented on a GAAP (reported) basis and on an adjusted basis. Adjusted earnings and adjusted diluted earnings per share exclude the effects of certain items, which are detailed in the reconciliations of these non-GAAP financial measures to the most directly comparable GAAP financial measures presented later in this press release.

Free cash flow from continuing operations is an additional non-GAAP measure that is presented in this press release. Free cash flow from continuing operations is computed by deducting additions to instruments and other property, plant and equipment from net cash provided by operating activities from continuing operations.

Reconciliations of these non-GAAP financial measures to the most directly comparable GAAP financial measures are included in this press release. This press release also contains

supplemental reconciliations of additional non-GAAP financial measures that the Company presents in other contexts. These additional non-GAAP financial measures are computed from the most directly comparable GAAP financial measure as indicated in the applicable reconciliation.

Management uses non-GAAP financial measures internally to evaluate the performance of the business. Additionally, management believes these non-GAAP measures provide meaningful incremental information to investors to consider when evaluating the performance of the Company. Management believes these measures offer the ability to make period-to-period comparisons that are not impacted by certain items that can cause dramatic changes in reported income but that do not impact the fundamentals of our operations. The non-GAAP measures enable the evaluation of operating results and trend analysis by allowing a reader to better identify operating trends that may otherwise be masked or distorted by these types of items that are excluded from the non-GAAP measures. In addition, constant currency sales changes, adjusted operating profit, adjusted diluted earnings per share and free cash flow are used as performance metrics in our incentive compensation programs.

Forward-Looking Non-GAAP Financial Measures

This press release also includes certain forward-looking non-GAAP financial measures for the year ending December 31, 2023. We calculate forward-looking non-GAAP financial measures based on internal forecasts that omit certain amounts that would be included in GAAP financial measures. For instance, we exclude the impact of certain charges related to initial compliance with the European Union Medical Device Regulation; restructuring and other cost reduction initiatives; acquisition, integration, divestiture and related; and certain legal and tax matters. We have not provided quantitative reconciliations of these forward-looking non-GAAP financial measures to the most directly comparable forward-looking GAAP financial measures because the excluded items are not available on a prospective basis without unreasonable efforts. For example, the timing of certain transactions is difficult to predict because management's plans may change. In addition, the Company believes such reconciliations would imply a degree of precision and certainty that could be confusing to investors. It is probable that these forward-looking non-GAAP financial measures may be materially different from the corresponding GAAP financial measures.

Cautionary Note Regarding Forward-Looking Statements

the base erosion and profit shifting project ( Pillar Two ) undertaken by the Organisation for Economic Co-operation and Development ( OECD ) and otherwise; challenges to the tax-free nature of the ZimVie Inc. ( ZimVie ) spinoff transaction and the subsequent liquidation of our retained interest in ZimVie; the risk of additional tax liability due to the recategorization of our independent agents and distributors to employees; the risk that material impairment of the carrying value of our intangible assets, including goodwill, could negatively affect our operating results; changes in general domestic and international economic conditions, including interest rate and currency exchange rate fluctuations; changes in general industry and market conditions, including domestic and international growth, inflation and currency exchange rates; the domestic and international business impact of political, social and economic instability, tariffs, trade restrictions and embargoes, sanctions, wars, disputes and other conflicts, including on our ability to operate in, export from or collect accounts receivable in affected countries; challenges relating to changes in and compliance with governmental laws and regulations affecting our U.S. and international businesses, including regulations of the FDA and foreign government regulators relating to medical products, healthcare fraud and abuse laws and data privacy and security laws; the success of our quality and operational excellence initiatives; the ability to remediate matters identified in inspectional observations or warning letters issued by the FDA and other regulators, while continuing to satisfy the demand for our products; product liability, intellectual property and commercial litigation losses; and the ability to obtain and maintain adequate intellectual property protection.

Risk Factors, and our subsequent filings with the Securities and Exchange Commission (SEC). Copies of these filings are available online at www.sec.gov, www.zimmerbiomet.com or on request from us. These factors should not be construed as exhaustive and should be read in conjunction with the other cautionary statements that are included in our filings with the SEC. Forward-looking statements speak only as of the date they are made, and we expressly disclaim any intention or obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise. Readers of this press release are cautioned not to rely on these forward-looking statements since there can be no assurance that these forward-looking statements will prove to be accurate. This cautionary note is applicable to all forward-looking statements contained in this press release.

Note: Amounts reported in millions within this press release are computed based on the actual amounts. As a result, the sum of the components reported in millions may not equal the total amount reported in millions due to rounding. Certain columns and rows within tables may not add due to the use of rounded numbers. Percentages presented are calculated from the underlying unrounded amounts.

(1)Inventory and manufacturing-related charges include excess and obsolete inventory charges on certain product lines we intend to discontinue and other inventory and manufacturing-related charges or gains.

(2)We exclude intangible asset amortization as well as deferred tax rate changes on our intangible assets from our non-GAAP financial measures because we internally assess our performance against our peers without this amortization. Due to various levels of acquisitions among our peers, intangible asset amortization can vary significantly from company to company.

(3)In December 2019 and 2021, we initiated global restructuring programs that included a reorganization of key businesses and an overall effort to reduce costs in order to accelerate decision-making, focus the organization on priorities to drive growth and to prepare for the spinoff of ZimVie. Restructuring and other cost reduction initiatives also include other cost reduction and optimization initiatives that have the goal of reducing costs across the organization. The costs include employee termination benefits; contract terminations for facilities and sales agents; and other charges, such as consulting fees, project management expenses, retention period salaries and benefits and relocation costs.

(4)The acquisition, integration, divestiture and related gains and expenses we have excluded from our non-GAAP financial measures resulted from various acquisitions, post-separation costs we have incurred related to ZimVie and gains related to a transition services agreement for services we provide to ZimVie and a transition manufacturing and supply agreement for products we supply to ZimVie for a limited period.

(5)The European Union Medical Device Regulation imposes significant additional premarket and postmarket requirements. The new regulations provided a transition period until May 2021 for previously-approved medical devices to meet the additional requirements. For certain devices, this transition period can be extended until May 2024. A conditional extension of the transition period has been implemented until December 2027 and 2028 depending on the legacy medical device's risk class. We are excluding from our non-GAAP financial measures the incremental costs incurred to establish initial compliance with the regulations related to our previously-approved medical devices. The incremental costs primarily relate to temporary personnel and third-party professionals necessary to supplement our internal resources.

(6)We have incurred other various expenses from specific events or projects that we consider highly variable or that have a significant impact to our operating results that we have excluded from our non-GAAP measures. These include costs related to contract terminations and gains and losses from changes in fair value on our equity investments including our investment in ZimVie, among other various costs.

(7)Other certain tax adjustments are related to certain significant and discrete tax adjustments including intercompany transactions between jurisdictions, ongoing impacts of tax only amortization resulting from certain restructuring transactions, impacts of significant tax reform including Swiss reform and certain favorable tax audit settlements.

(8)We are involved in patent litigation, product liability litigation, commercial litigation and other various litigation matters. We review litigation matters from both a qualitative and quantitative perspective to determine if excluding the losses or gains will provide our investors with useful incremental information. Litigation matters can vary in their characteristics, frequency and significance to our operating results. The litigation charges and gains excluded from our non-GAAP financial measures in the periods presented relate to patent litigation and product liability litigation. Once the litigation matter has been excluded from our non-GAAP financial measures in a particular period, any additional expenses or gains from changes in estimates are also excluded, even if they are not significant, to ensure consistency in our non-GAAP financial measures from period-to-period.

(9)In the second quarter of 2022, we recognized an impairment charge of $3.0 million on a certain in-process research and development project.

(10)We addressed inspectional observations on Form 483 and a Warning Letter issued by the U.S. Food and Drug Administration ( FDA ) following its previous inspections of our Warsaw North Campus facility, among other matters. This quality remediation required us to devote significant financial resources. The majority of the expenses were related to consultants who helped us to update previous documents and redesign certain processes.
