Financial Information

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.

Adjusted EBITDA is a non-GAAP financial measure provided in this release for certain periods, and is calculated by excluding certain items from net loss from Continuing Operations or Discontinued Operations, as applicable, on a GAAP basis, as detailed in the reconciliations presented later in this press release. Adjusted EBITDA margin is Adjusted EBITDA divided by third party net sales from Continuing Operations or Discontinued Operations, as applicable, for the applicable period.

Sales change information in this release 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 from Continuing Operations or Discontinued Operations, as applicable, at the same predetermined exchange rate. The translated results are then used to determine year-over-year percentage increases or decreases.

Net loss and diluted loss per share in this release are presented on a GAAP (reported) basis and on an adjusted basis. Adjusted net income 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.

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

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.

Forward-Looking Non-GAAP Financial Measures

This press release also includes certain forward-looking non-GAAP financial measures for the quarter ending March 31, 2024 and the twelve-month period following the closing of the sale of the spine business. We calculate forward-looking non-GAAP financial measures based on internal forecasts that omit certain amounts that would be included in GAAP financial measures. 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.

[1] In April 2023, we initiated restructuring activities to better position our organization for future success based on the current business environment, and in July 2023, we took additional actions. The expenses incurred were primarily related to severance and professional fees. In June 2022 we initiated a restructuring plan and the expenses incurred were primarily related to employee termination benefits.
[2] Acquisition, integration, divestiture, and related expenses include costs incurred to prepare for and complete the separation from our former parent (such as professional fees, transition services agreements, costs to stand up our corporate organization and infrastructure), changes in the fair value of contingent consideration for acquisitions closed prior to the separation date and costs related to the evaluation of strategic options for our portfolio. Acquisition, integration, divestiture and related expenses increased by $6.3 million in 4Q 2023 compared to 4Q 2022, due primarily to increased costs related to the pending sale of our spine segment ($10.1 million), partially offset by decreases in separation-related professional fees ($2.0 million), separation-related employee costs ($0.3 million) and separation-related lease costs ($0.1 million).
[3] Expenses incurred for initial compliance with the European Union (“EU”) Medical Device Regulation (“MDR”) for previously-approved products. 
[4] Inventory write-offs resulting from restructuring activities and property, plant, and equipment step-up amortization from prior acquisitions.
[5] Spin-related share-based compensation expense from grants provided due to the successful separation from Zimmer Biomet, including the impact of accelerating the vesting of these awards in Q4 2023.
[6] Reflects the tax effect of the adjustments from reported to adjusted, as well as an adjustment for management’s expectation of ZimVie’s statutory tax rate based on current tax law and adjusted pre-tax income.

[1] We performed an impairment analysis of the spine segment in December 2023 on a held-for-sale basis, and the fair value of consideration to be received upon closure of the transaction was less than the carrying value of the spine segment's net assets.
[2] In April 2023, we initiated restructuring activities to better position our organization for future success based on the current business environment, and in July 2023, we took additional actions. The expenses incurred under this plan were primarily related to severance and professional fees. In June 2022 and November 2022, we initiated restructuring plans and the expenses incurred were primarily related to employee termination benefits and the exit of our spine products operations in China because of an unsuccessful volume-based procurement program bid. We also incurred expenses in 2022 from the Zimmer Biomet initiated restructuring plans in the fourth quarters of 2019 and 2021 and the restructuring costs we incurred under those plans were primarily related to employee termination benefits, contract terminations and retention period compensation and benefits.
[3] Acquisition, integration, divestiture, and related expenses include costs incurred to prepare for and complete the separation from our former parent (such as professional fees, transition services agreements, costs to stand up our corporate organization and infrastructure), changes in the fair value of contingent consideration for acquisitions closed prior to the separation date and costs related to the evaluation of strategic options for our portfolio. Acquisition, integration, divestiture and related expenses in 4Q 2023 were comparable to 4Q 2022. Acquisition, integration, divestiture and related expenses decreased by $2.7 million in 2023 compared to 2022, due primarily to decreases in separation-related professional fees ($2.8 million).
[4] Expenses incurred for initial compliance with the EU MDR for previously-approved products. 
[5] The 2023 amounts represent inventory write-offs resulting from restructuring activities and property, plant, and equipment step-up amortization from prior acquisitions. The 2022 amounts represent expenses captured through allocations made for purposes of the GAAP carve-out financial statement results.
[6] Net Loss Margin is calculated as Net Loss divided by third party net sales for the applicable period.
[7] Adjusted EBITDA Margin is Adjusted EBITDA divided by third party net sales for the applicable period.
