COHR Delivers Strong Q1: Gross Margin Expands and Datacenter Growth Leads to 19% Revenue Increase
Datacenter and Communications Propel Revenue Growth to 19% Year-Over-Year
Coherent Corp. (NYSE: COHR) started fiscal 2026 with a clear statement: business is accelerating. The company posted first quarter revenue of $1.58 billion, representing a 19% year-over-year increase on a pro forma basis, adjusted for its recent divestiture of the Aerospace & Defense business. The growth story is fueled largely by demand in AI-driven datacenters and communications, with this segment reaching $1.09 billion—up 26% compared to a year ago.
Gross Margin Expansion Signals Operational Improvements
COHR’s gross margin metrics are a highlight this quarter, with GAAP gross margin rising 249 basis points to 36.6% and non-GAAP gross margin hitting 38.7%—a 200 basis point increase. This is more than just a percentage uptick; the improvement underscores the company’s operational efficiency and the immediate benefits of its business realignment efforts. Notably, the sale of the Aerospace & Defense business was described as accretive to both gross margin and earnings per share (EPS).
| Metric | Q1 FY26 | Q4 FY25 | Q1 FY25 | Q/Q Change | Y/Y Change |
|---|---|---|---|---|---|
| Revenue ($M) | 1,581 | 1,529 | 1,348 | +3.4% | +17.3% |
| GAAP Gross Margin (%) | 36.6 | 35.7 | 34.1 | +93 bps | +249 bps |
| Non-GAAP Gross Margin (%) | 38.7 | 38.1 | 36.7 | +67 bps | +200 bps |
| Non-GAAP EPS ($) | 1.16 | 1.00 | 0.67 | +0.16 | +0.49 |
Profitability and Operating Efficiency Hit Multi-Year Highs
Coherent delivered $226 million in GAAP net earnings attributable to the company (a major turnaround from last quarter’s $95.6 million loss), with diluted EPS swinging to $1.19. On a non-GAAP basis, net earnings climbed nearly 60% year-over-year to $221 million. Operating income surged as well, while operating margin reached 16.4% GAAP and 19.5% non-GAAP—far above last year’s levels.
The company’s strategic moves are having a direct impact on the balance sheet. Operating expenses on a GAAP basis dropped by nearly 17% from the prior year, reflecting tighter cost controls and benefits from the streamlined business portfolio. In parallel, $400 million in debt repayment and refinancing should meaningfully reduce future interest expenses.
Innovation and Awards Bolster Outlook for Datacenter Technology
Alongside robust financials, Coherent highlighted significant advances in its product lineup. The company introduced a high-power 400 mW continuous wave (CW) laser and claimed two major industry awards for photonics innovation—each reinforcing its leadership in powering next-generation datacenter and communications networks.
CEO Jim Anderson expressed optimism for the rest of the fiscal year, citing “continued production capacity expansion” and accelerating demand from AI-related applications as primary growth drivers. Guidance for the next quarter remains strong, with projected revenues between $1.56 and $1.70 billion, and non-GAAP gross margin anticipated between 38% and 40%.
| Business Segment | Q1 FY26 Revenue ($M) | Q1 FY25 Revenue ($M) | Y/Y Growth (%) |
|---|---|---|---|
| Datacenter & Communications | 1,090.0 | 863.6 | +26.2% |
| Industrial | 491.4 | 484.5 | +1.4% |
Key Takeaways: Financial Flexibility and Market Focus Drive Upside Potential
For investors and industry watchers, Coherent’s Q1 numbers show more than headline growth—they reflect an ongoing business transformation targeting higher-value markets. Margin expansion, product innovation, and substantial debt reduction provide both financial stability and agility for the company as AI adoption continues to scale.
Looking ahead, Coherent is set up for further strength if demand in the datacenter and communications space persists. As always, guidance will depend on how those secular growth drivers hold up—and on the company's ability to keep delivering efficiency and innovation quarter after quarter.
