NEW YORK, August 12, 2026, 16:38 EDT
Coherent Corp. NYSE:COHR shares reversed sharply after Wednesday’s close. The photonics maker fell 7.2% to $330 in preliminary after-hours trading. That nearly erased an 8.2% regular-session rally.
The reversal came despite a clean earnings beat. Fiscal fourth-quarter revenue reached $2.05 billion, 3.3% above consensus. Adjusted earnings of $1.74 also topped the $1.62 estimate.
The message is about the bar, not demand. Coherent had entered the release after a powerful AI-optics rerating. Its market value stood near $70 billion at the close.
| COHR price tape | Price | Move |
|---|---|---|
| Tuesday close | $328.55 | — |
| Wednesday close | $355.64 | +8.24% |
| After hours, preliminary | $330.00 | -7.21% from close |
| Net move from Tuesday | about $1.45 | about +0.44% |
Demand still accelerated. Datacenter and communications sales rose 59% to $1.62 billion. That unit supplied 79% of quarterly revenue, up from 67% a year earlier.
| Fiscal Q4 metric | 2026 | 2025 | Change |
|---|---|---|---|
| Revenue | $2.05 billion | $1.53 billion | +34% reported; +42% pro forma |
| Datacenter and communications revenue | $1.62 billion | $1.02 billion | +59% |
| Non-GAAP gross margin | 40.2% | 38.1% | +215 basis points |
| Non-GAAP EPS | $1.74 | $1.00 | +74% |
Management expects another step higher. The September-quarter revenue midpoint is $2.30 billion. That implies roughly 12% sequential growth, while the gross-margin midpoint rises only 30 basis points.
| Fiscal Q1 2027 outlook | Company range | Midpoint | Sequential change at midpoint |
|---|---|---|---|
| Revenue | $2.20-$2.40 billion | $2.30 billion | about +12.4% |
| Non-GAAP gross margin | 39.5%-41.5% | 40.5% | about +30 basis points |
| Non-GAAP EPS | $1.85-$2.05 | $1.95 | about +12.1% |
That mix helps explain the selloff. Revenue is scaling fast, but capacity spending remains heavy. Coherent says internal indium-phosphide output should double by year-end, then more than double again during 2027.
Chief Executive Jim Anderson said, “We enter fiscal 2027 with exceptional customer demand, expanding production capacity, and multiple new growth platforms beginning to ramp.” The company now sees more than $20 billion of added serviceable market by 2030.
Peer results raised expectations further. Lumentum Holdings Inc. NASDAQ:LITE reported a 50.4% adjusted gross margin earlier Wednesday. Its strong outlook lifted Coherent before the bell.
Wall Street remained broadly constructive before the release. Four of six recent analysts rated Coherent a buy. The average target was $415, but the range stretched from $330 to $465.
| Analyst | Firm | Recommendation | Target | Date |
|---|---|---|---|---|
| Samik Chatterjee | J.P. Morgan | Buy | $435 | July 21 |
| Simon Leopold | Raymond James | Buy | $435 | July 1 |
| Michael Genovese | Rosenblatt Securities | Buy | $425 | June 24 |
| Saiyi He | CMB International | Buy | $465 | June 12 |
| Meta Marshall | Morgan Stanley | Hold | $330 | June 12 |
| Vivek Arya | Bank of America | Hold | $400 | May 13 |
Coherent’s balance sheet carries unusual strategic support. NVIDIA Corp. NASDAQ:NVDA invested $2 billion in March. The agreement also included a multibillion-dollar purchase commitment for optical products.
Risks: The outlook assumes rapid capacity ramps and durable hyperscaler demand. Execution delays, customer concentration, export controls or a slower AI buildout could pressure margins.
For investors, the next test is operating leverage. Another revenue record may not suffice. The market now wants faster margin conversion from Coherent’s expanding optics capacity.
