Item 2.02 Results of Operations and Financial Condition.
On January 21, 2026, MKS Inc. (the “Company”), in connection with a meeting between the Company and existing and prospective lenders, expected to be held on January 22, 2026 to discuss potential debt refinancing activity, updated certain of its previously issued financial guidance for the quarter ended December 31, 2025. The Company now expects to report revenue of approximately $1,030 million, plus or minus $5 million, GAAP net income of $106 million, plus or minus $3 million, and Adjusted EBITDA of $248 million, plus or minus $2 million. The Company also expects gross margin, Non-GAAP net earnings, GAAP net income per diluted share and Non-GAAP net earnings per diluted share for the quarter ended December 31, 2025 to exceed the midpoint of the previously issued guidance, while GAAP operating expenses and Non-GAAP operating expenses are expected to be slightly higher than the previously issued guidance range. The increase of $40 million to the midpoint of the Company’s updated revenue guidance for the quarter ended December 31, 2025, compared to the previously issued guidance, is primarily due to increased demand across all markets and divisions. The increases in the Company’s GAAP net income and Adjusted EBITDA guidance for the quarter ended December 31, 2025 are primarily due to the increase in net revenues and higher gross margin, partially offset by an increase in operating expenses, mainly from higher variable compensation as well as higher restructuring and other charges. The information in Item 2.02 of this Current Report on Form 8-K contains financial guidance with respect to the Company’s anticipated financial results for the three months ended December 31, 2025. This financial guidance is based on a number of assumptions, and the Company has not yet completed its closing procedures with respect to its quarter and year ended December 31, 2025. The financial guidance should not be viewed as a substitute for full quarterly and year ended financial statements prepared in accordance with GAAP and reviewed or audited by the Company’s independent auditors. Actual results remain subject to the completion of the Company’s closing procedures with respect to its quarter and year ended December 31, 2025, the Company’s management’s and audit committee’s final review of its actual results, as well as review and audit by the Company’s independent auditors. There can be no assurance that the Company’s actual financial results for the quarter and year ended December 31, 2025 will not differ from the guidance set forth herein and any variation may be material. Adjusted EBITDA, Non-GAAP net earnings, Non-GAAP net earnings per diluted share and Non-GAAP operating expenses are financial measures that are not in accordance with U.S. generally accepted accounting principles (“Non-GAAP financial measure”). These Non-GAAP financial measures should be
