AI Brief
Q3 FY26 earnings call · Nov 5, 2026TL;DR. MKS delivered record Q3 revenue, earnings and adjusted EBITDA above guidance, expanded operating margin sharply, and guided to 44% Q4 revenue growth amid strong orders and improving visibility. Strong free cash flow, lower leverage and the $500 million repurchase authorization support capital returns. Risks include gross-margin headwinds, a nonrecurring tariff refund, customer supply-chain constraints, industry scaling challenges, rapidly changing cycles and trade-policy exposure.
- + Record adjusted EBITDA of $434 million and non-GAAP diluted EPS of $4.18 were each above the high end of guidance.
- + Non-GAAP operating margin expanded approximately 700 basis points year over year to 27.8%, the highest quarterly operating margin in over eight years.
- − Lower-margin chemistry equipment mix and manufacturing-expansion costs are expected to continue pressuring gross margin into next year.
- − Q3 gross margin included a 30-basis-point benefit from tariff refunds that management does not expect to repeat in Q4.
- − Some customers have reported constraints elsewhere in their supply chains.
- − Increasing industry WFE by another $40 billion or $50 billion will be a supply-chain scaling challenge.
- − U.S. import tariffs and retaliatory actions by other countries remain stated risks to the business environment.

Dividends per share over the trailing 365 days by ex-date · buyback figures as last reported in SEC filings ("spent" derived as authorized − remaining; when several programs run concurrently, authorized is their combined total per the newest filing) · components shown separately — trailing-year buyback spend isn't tracked, so no combined shareholder yield is derived.
