Third-quarter results beat expectations—which businesses contributed the incremental growth?

Revenue and profit both exceeded institutional benchmarks, but growth was not led across the board by the semiconductor business.

  • MKS reported third-quarter revenue of 1.413 billion dollars, up 43% year over year and 13.2% quarter over quarter; this was above Goldman Sachs' estimate of 1.362 billion dollars and Visible Alpha's consensus estimate of 1.358 billion dollars. Non-GAAP earnings per share were 4.18 dollars, also above Goldman Sachs' estimate of 3.71 dollars and the market consensus of 3.64 dollars.
  • Electronics and Packaging revenue was 415 million dollars and Specialty Industrial revenue was 360 million dollars, both above Goldman Sachs' estimates of 385 million and 335 million dollars, respectively. Semiconductor revenue of 638 million dollars was slightly below Goldman Sachs' estimate of 643 million dollars and broadly in line with the market estimate of 636 million dollars. Third-quarter gross margin was 47.7%, above Goldman Sachs' estimate of 47.0% and the market estimate of 47.2%.

Why was fourth-quarter guidance well above expectations?

The midpoint of the company's revenue and earnings-per-share guidance was both notably above Goldman Sachs' and market expectations.

  • The midpoint of fourth-quarter revenue guidance was 1.49 billion dollars, above Goldman Sachs' estimate of 1.391 billion dollars and the market estimate of 1.403 billion dollars. The midpoint of semiconductor revenue guidance was 700 million dollars, above Goldman Sachs' estimate of 655 million dollars; Electronics and Packaging guidance was 430 million dollars, above Goldman Sachs' estimate of 400 million dollars and the market estimate of 391 million dollars.
  • The midpoint of fourth-quarter non-GAAP earnings-per-share guidance was 5.00 dollars, compared with Goldman Sachs' estimate of 3.88 dollars and the market estimate of 3.92 dollars; this partly reflects the company's expected 9% lower tax rate. The midpoint of gross-margin guidance was 47.5%, above Goldman Sachs' and the market's estimate of 47.1%, although capacity investment and a lower-margin mix of chemical equipment remain near-term pressures.

How long can AI chemicals and capacity expansion sustain growth?

Bookings visibility extends through 2028, but the growth trajectory depends on capacity coming online and the pace of subsequent investment.

  • Chemical revenue grew 26% year over year. Goldman Sachs said that in 2026, AI-related chemical revenue could approach the upper end of the 15%–20% range as a share of chemical revenue in the Electronics and Packaging business, while AI is expected to account for 25% of full-year Electronics and Packaging revenue. As the installed base expands, the company expects high-margin proprietary chemical consumables to become a source of subsequent growth; more-layered, more complex PCBs are another demand driver.
  • Management expects the wafer fabrication equipment (WFE) market to approach 300 billion dollars by 2028 and believes the semiconductor business will grow significantly faster than the overall WFE market in the coming quarters. Chemical equipment capacity is sold out through 2027, with bookings extending through 2028; the Guangzhou expansion project, targeted to begin production in the third quarter of 2027, will double capacity and support faster growth in the second half of 2027. The company plans to maintain capital expenditure at 3%–5% of revenue.
  • Goldman Sachs also noted that NAND upgrade demand is expected to remain strong through 2027, but investment in large new-build projects will only gradually begin at the end of 2027 or in 2028. A near-term mix weighted toward lower-margin chemical equipment and capacity expansion spending will also weigh on gross margin; the company expects an incremental gross margin of about 50% in the near term.

Why does Goldman Sachs maintain a Sell rating despite raising earnings estimates?

Goldman Sachs is positive on earnings growth from the industry's upcycle, but its rating reflects its view of MKS's near-term performance relative to peers.

  • Goldman Sachs raised its earnings-per-share estimates for 2026–2028 by an average of about 14%, to 15.03 dollars, 20.00 dollars and 23.00 dollars, respectively. However, it believes NAND spending, particularly investment in new capacity, may lag investment in DRAM and foundry/logic chips significantly, and that MKS may underperform peers in the near term; it therefore maintained its Sell rating, the lowest among the companies it covers.
  • Goldman Sachs cut its 12-month price target from 270 dollars to 250 dollars. Despite higher earnings estimates, the target valuation multiple was reduced from 20 times earnings to 18 times as peer valuations declined; the normalized earnings-per-share estimate used remains 13.50 dollars.
