Coherent reports Q4 earnings with $2B revenue, guides Q1 at roughly $2B

Coherent Corp. delivered fiscal Q4 2026 results that topped Wall Street expectations, posting revenue in the neighborhood of $2 billion for the quarter. The company’s guidance for Q1 of fiscal year 2027 suggests it plans to stay right around that level.

For a company that was generating $1.81 billion in quarterly revenue just one quarter earlier, crossing the $2 billion threshold represents a meaningful inflection point. That Q3 figure itself was already a 21% jump year-over-year.

The AI optics gold rush

The company had guided Q4 FY2026 revenue between $1.91 billion and $2.05 billion. Analyst consensus had settled at roughly $1.99 billion, suggesting the Street largely believed Coherent would land near the upper half of that range. The actual results came in above those expectations.

NVIDIA’s $2 billion vote of confidence

Perhaps the most telling signal of Coherent’s strategic importance came back in March 2026, when NVIDIA announced a $2 billion investment to establish a multiyear partnership with the company. The deal focuses on developing next-generation optics technology specifically designed for AI data center applications.

The partnership spans both supply expansion and R&D capabilities, meaning NVIDIA isn’t just buying more of what Coherent already makes.

Manufacturing expansion and CHIPS Act funding

In June 2026, the company secured a letter of intent for $50 million in funding under the CHIPS Act. The money is earmarked for its indium phosphide manufacturing facility in Sherman, Texas, where the plan is to double existing production space and quadruple wafer output.

What the Q1 guidance tells us

The Q1 FY2027 guidance landing around the $2 billion mark is quietly significant. In semiconductor and component businesses, sequential revenue guidance that holds flat after a strong quarter usually means the company sees sustainable demand rather than a one-time surge followed by digestion.
