As a global developer, manufacturer and marketer of medical devices, our business is subject to local and international macroeconomic trends as well as geopolitical factors. While global supply chain disruptions continued to improve recently, we have experienced, and may continue to experience, increases in cost and limited availability of certain raw materials, components, and other inputs necessary to manufacture and distribute our products due to constraints and inflation within the global supply chain, as well as increases in wage costs and the cost and time to distribute our products. Uncertainty around inflationary pressures, interest rates, monetary policy, trade and tariff policies, foreign currency fluctuations and changes in tax laws, as well as actions by governments in response thereto, could create additional economic challenges which could negatively impact our business operations and results. We anticipate incurring incremental costs under the current schedule of reciprocal tariffs on U.S. imports recently introduced by the U.S. and the subsequent increase in tariffs implemented by China on U.S. manufactured products; these and any further tariff increases on our products by the U.S., China or any other country as well as sanctions or other measures that restrict international trade could materially negatively affect our business operations and results. While we are exploring opportunities to mitigate these negative impacts, there can be no guarantee that we will be able to offset the impact of tariffs, the ultimate impact of which will depend on various factors, including the timing, scope, and nature of any tariffs or other trade policies. In addition, geopolitical developments, including related to various ongoing global conflicts and tensions, may create economic, supply chain, transportation, energy, and other challenges, including disruptions to business operations, which could negatively impact our business and results of operations.

The Company continues to monitor further legislative adoption of the Pillar Two rules by country. The United States has not enacted the Pillar Two global minimum tax, and the current administration announced its intention to effectively withdraw from the OECD Inclusive Framework as well as its intention to enact retaliatory measures against countries who assert extraterritorial taxes against U.S. taxpayers. In addition, significant uncertainty exists regarding the interpretation of the detailed Pillar Two rules, whether such rules will be implemented consistently across taxing jurisdictions, how such rules interact with existing national tax laws and whether such rules are consistent with existing tax treaty obligations. Developments related to these uncertainties could impact our expectations regarding the impact of the Pillar Two global minimum tax on our tax rate from continuing operations in 2025.

Current wording

Effective January 1, 2024, many countries where we do business adopted a global minimum effective tax rate of 15% based on the Pillar Two framework issued by the Organization for Economic Cooperation and Development (OECD). The United States has not enacted the Pillar Two global minimum tax and as of June 28, 2025 the G7 countries announced an agreement to exempt U.S. companies from certain elements of the OECD global minimum tax framework. We expect that this agreement, if ultimately enacted into law in the relevant countries, would be beneficial to the Company. However, Pillar Two remains enacted law and significant uncertainty exists regarding the implementation of this agreement, the interpretation of the existing Pillar Two rules, whether such rules will be implemented consistently across taxing jurisdictions, how such rules interact with existing national tax laws and whether such rules are consistent with existing tax treaty obligations. Developments related to these uncertainties could impact our expectations regarding the impact of the Pillar Two global minimum tax on our tax rate from continuing operations in 2025 and beyond.

Current wording

As of June 30, 2025, we had $534 million of unrestricted Cash and cash equivalents on hand, including approximately $89 million held by Acotec Scientific Holdings Limited, a less than wholly owned entity of which we acquired a majority stake investment during the first quarter of 2023. The balance is comprised of $146 million invested in money market funds and time deposits and $388 million in interest bearing and non-interest-bearing bank accounts. We invest excess cash on hand in short-term financial instruments that earn at market interest rates while mitigating principal risk through instrument and counterparty diversification, as well as what we believe to be prudent instrument selection. We limit our direct exposure to securities in any one industry or issuer.
