MKS Instruments posts record Q3 results and raises Q4 outlook

MKS Instruments reported third‑quarter 2026 revenue of about $1.41 billion, GAAP net income of $236 million and adjusted earnings per share of $4.18, beating analysts’ expectations. Semiconductor revenue jumped 54% year‑over‑year, while the company announced a $650 million sale of its Ophir Optics business and a $500 million share‑repurchase authorization. For the fourth quarter it guided revenue of $1.49 billion (± $40 million) and GAAP EPS of $4.04 (± $0.38).

The strong earnings and upbeat Q4 guidance suggest higher cash flow and may support the planned share‑repurchase and balance‑sheet reduction, which could be positive for shareholders. The $650 million Ophir Optics sale provides additional liquidity for debt repayment and future investments.
