AI Analysis

AI-generated, general educational analysis — not personal investment advice.

I look for durable businesses bought at sensible prices. MKS sells foundational technology into semiconductor manufacturing, electronics and packaging, and specialty industrial markets. That can create a technical moat, but it is also cyclical and capital-intensive. The filed record shows a genuine turnaround: in fiscal 2023, the year ended 2023-12-31, net income was -$1.8B and diluted EPS -$27.54. By fiscal 2025, the year ended 2025-12-31, revenue was $3.9B, net income $295.0M, and diluted EPS $4.37. More recently, in fiscal Q2 2026, the quarter ended 2026-06-30, revenue was $1.2B, net income $175.0M, and diluted EPS $2.41; in fiscal Q2 2025, the quarter ended 2025-06-30, those figures were $973.0M, $62.0M, and $0.92. That is strong momentum. Financial health is mixed: FairStock calculations show a Piotroski F-score of 8/9 and TTM free cash flow of $455.0M, but debt-to-equity is 1.40, Altman Z-score is 2.12, and ROCE is 5.02%, so this is not a fortress. Valuation is the rub. At the $247.56 close on 2026-10-13, FairStock shows P/E 39.42, P/B 5.60, FCF yield 2.7%, EV/EBITDA 19.84, and Graham Number $79.03, a -213.25% margin of safety. PEG 0.64 hints growth may justify part of the multiple, but Graham would demand a much larger discount. FairStock Score 33/100 and the Lynch TURNAROUND label fit: improving, but not cheap. I would want evidence that returns on capital and free cash flow persist before calling it a bargain.

In plain English: MKS makes tools and parts used to make computer chips, electronics, and industrial equipment. It lost a lot of money in 2023, but it has returned to profit and recent quarterly sales and earnings are higher than a year earlier. At the $247.56 close on 2026-10-13, the stock looks expensive compared with its profits and asset value, and its price has swung widely.
