Future Outlook

MKS Inc. expects international net revenues to continue accounting for a significant percentage of total net revenues for the foreseeable future. The company believes its current cash, investments, and available borrowing capacity, combined with anticipated cash from operations, will be sufficient to meet estimated working capital needs, planned capital expenditures, debt payments, potential convertible debt conversions, dividends, and share repurchases for at least the next 12 months and the foreseeable future. The company anticipates an immaterial impact from the 15% global minimum corporate tax rate (Pillar Two) and the One Big Beautiful Bill Act (OBBBA) on future financial results. However, it expects to face challenges in sourcing critical materials, such as rare earth minerals like yttrium, due to China's export restrictions, which may lead to higher costs and potential supply chain disruptions that could materially harm its business, financial condition, and operating results. The recent debt refinancing and prepayments are projected to yield approximately $27 million in annualized cash interest savings.
