KLA revenue guidance for the December 2026 quarter
Source: KLA FQ1 2027 results release (Form 8-K, Exhibit 99.1), Guidance issued 28 October 2026.
KLA expects revenue of $4.7bn, plus or minus $200m, in the second quarter of fiscal 2027, which ends in December, according to the results release it furnished to the SEC at 4:07 PM ET (21:07 CET) on 28 October 2026. At the midpoint that would be about 14% above the $4.14bn ($4,136m) it reported for the September quarter, by Polstob's calculation. It also guides to GAAP diluted EPS of $1.41 and non-GAAP diluted EPS of $1.44, each plus or minus $0.11, and a non-GAAP gross margin of 62.5%, plus or minus 1 point. KLA's July release gave guidance only for the September quarter, so there is no earlier company forecast for the December quarter to compare with.
| Metric | Guidance (28 July 2026) | Reported |
|---|---|---|
| Revenue | $4.0bn +/- $200m | $4,136m |
| GAAP diluted EPS | $1.14 +/- $0.10 | $1.18 |
| Non-GAAP diluted EPS | $1.16 +/- $0.10 | $1.22 |
Source: KLA results releases (Form 8-K, Exhibit 99.1), 28 July and 28 October 2026, Fiscal Q1 2027 (to 30 September). Revenue landed above the midpoint but inside the $3.8bn-$4.2bn range. Per-share figures reflect the ten-for-one split effective 11 June 2026.
Revenue rose 29% from $3,210m a year earlier and 13% from $3,658m in the June quarter. GAAP net income was $1.55bn, or $1.18 a diluted share, against $0.85 a year earlier; non-GAAP diluted EPS was $1.22, against $0.88 a year earlier. Semiconductor Process Control, the largest segment, brought in $3,754m, up from $2,899m a year earlier.

“KLA’s September quarter beat the midpoint of guidance across all key metrics, demonstrating the accelerated growth we expected for the second half of calendar 2026.”
Wallace tied demand for process control to the build-out of AI infrastructure, citing leading-edge foundry and logic designs, memory and advanced packaging. Operating cash flow was $1.53bn and free cash flow (non-GAAP) $1.34bn in the quarter. KLA returned $1.24bn to shareholders, including $936m of share repurchases and $305m of dividends, according to the cash-flow statement. Capital expenditures roughly doubled to $195m from $96m a year earlier.
KLA shares were up 3.23% at $163.90 in early after-hours trading as of 4:58 PM ET (21:58 CET) on 28 October, according to Nasdaq.com, a price that was still moving; they had risen 3.33% to $158.77 in the regular session. Investing.com linked the gain to results above analysts' expectations and a December-quarter outlook it called stronger than expected. Non-GAAP EPS of $1.22 was about 3.4% above the $1.18 consensus from eight estimates on Nasdaq.com, Polstob's comparison; the site records $1.05 for the June quarter, KLA's non-GAAP figure, so the basis matches. Revenue of $4.14bn was above the $4.04bn forecast cited by Investing.com, Polstob's comparison.
