This is a dated snapshot, not a live quote. “Today” refers to the 2026-10-22 U.S. market session.

What is behind the stock move?

Coherent was sharply lower in the October 22 regular-session snapshot. No single same-day company announcement was verified as the cause, so this report does not attribute the decline to a new earnings release. The latest published results cover fiscal Q4 2026, released August 12; the next earnings announcement is scheduled for November 4 after the close. The financial background and conditional chart levels below should be distinguished from today’s intraday move.

Latest company research

Coherent’s latest reported quarter delivered $2.05 billion in revenue, up 34% year over year; its next results are due November 4 after the close.

Fiscal 2026 revenue reached $7.118 billion, increasing 22.5% from fiscal 2025.
Fourth-quarter GAAP EPS was $1.19, while adjusted EPS reached $1.74 versus $1.00 a year earlier.
Fourth-quarter gross margin was 38.5% on a GAAP basis and 40.2% on an adjusted basis.
Datacenter and Communications generated $5.275 billion of annual revenue, about 74% of the total; Industrial contributed $1.844 billion.
Management’s August outlook called for fiscal Q1 2027 revenue of $2.2–$2.4 billion and adjusted EPS of $1.85–$2.05.
The October 21 close was $237.53; today’s selloff is separate from the completed-session charts and is not a new earnings release.

A sustained recovery requires price stabilization and reclaimed resistance; a large decline alone does not confirm a reversal.

Technical setup and risks

Conditional recovery: reclaim and hold $244, then reassess the prior $248–264 resistance area. The $231–236 and $217–222 zones come from completed daily bars and may already be broken by the October 22 selloff. Below $217, downside risk remains; require stabilization rather than treating a large decline or low RSI as a buy signal.
