Coherent, Inc. (COHR) drops 6.6% after earnings miss
Coherent, Inc. (COHR) drops after its fiscal Q4 earnings update sparked a sharp selloff. The stock fell on a big EPS miss versus estimates, even as investors continue to weigh its AI optics exposure, NVIDIA partnership, and long-term growth plans.
Coherent, Inc. (COHR) drops 6.6% after its fiscal Q4 earnings announcement, as investors reacted to a sharp EPS miss versus expectations. The selloff reflects a higher bar for execution in a premium-valued AI optics name, even though Coherent still has strong exposure to data-center networking and long-term photonics demand. For investors, the move signals that growth alone is no longer enough; earnings quality now matters more.
Coherent, Inc. (COHR) drops 6.56% to $332.30 in regular-session trading at 3:04 p.m. ET on Aug. 13, 2026. Volume is running at 1.8x its 200-day average, signaling a major repricing after the company’s Aug. 12 fiscal fourth-quarter earnings announcement.
Key Takeaways
COHR fell 6.56% to $332.30 while relative volume reached 1.8x the 200-day average.
The clearest catalyst was the fiscal Q4 earnings announcement after the Aug. 12 close.
Quarterly EPS came in at $0.74 versus a $1.43 estimate, producing a -48.3% surprise.
Coherent still has strong AI optics exposure, an NVIDIA partnership, and a $50 million CHIPS-related manufacturing expansion plan.
The drop raises the standard for execution because COHR trades at a 155.98 P/E and carries a 2.107 beta.
What Is Behind Coherent Stock’s Selloff Today
The most likely catalyst is Coherent’s fiscal Q4 and fiscal-year earnings announcement on Aug. 12 after the market close. The timing fits the move, and the earnings history provides a specific reason for concern.
COHR reported quarterly EPS of $0.74, compared with an estimated $1.43. That equaled a -48.3% surprise. The result stands out because the company beat estimates in 7 of the 8 quarters listed in its recent earnings history.
The earnings picture was mixed rather than uniformly weak. An Aug. 13 news headline described the quarter as a Q4 beat with a raised outlook, while the earnings history showed a sharp EPS miss. That combination can produce a sell-the-news reaction when a stock has already rallied on strong AI infrastructure expectations.
The trading range reinforces that interpretation. Research for Aug. 13 showed COHR moving between an intraday high of $361.18 and a low of $329.87. The stock’s rapid reversal, combined with roughly 10 million shares traded, fits earnings-driven repositioning more closely than a routine drift.
How Coherent’s Earnings and Valuation Frame the Drop
Coherent entered the event with solid operating momentum. In fiscal Q3 2026, revenue reached $1.81 billion. GAAP gross margin was 37.7%, and GAAP net income was $0.97 per diluted share.
The company had also guided fiscal Q4 revenue to a range of $1.91 billion to $2.05 billion. That guidance created a high bar. Strong demand alone was not enough if profitability failed to match the growth narrative.
Valuation makes that gap more important. Coherent has a $65.01 billion market capitalization, a listed EPS of $2.28, and a 155.9825 P/E. At that multiple, investors pay for continued execution across AI networking and photonics. A large EPS miss therefore matters more than it would for a low-multiple industrial stock.
The stock also carries a 2.107 beta. That figure points to greater sensitivity than the broader market. As a result, a single earnings surprise can create a wide price swing even when the long-term business story remains intact.
Coherent is more than a single-product semiconductor supplier. Its three operating segments are Networking, Materials, and Lasers. The Networking segment supplies transceivers, modules, optics, systems, and related devices for data centers and communications.
That breadth supports Coherent’s competitive position in photonics and optical networking. Its named peers include Lumentum (LITE) and Applied Optoelectronics (AAOI). Coherent’s global manufacturing footprint and broad technology stack give it scale as customers build larger AI data centers.
The company also announced a strategic partnership with NVIDIA (NVDA) focused on optics for next-generation data center architecture. In addition, Coherent announced a $50 million CHIPS letter of intent tied to expanded manufacturing for AI infrastructure optical networking.
Co-packaged optics remains another long-term growth theme. Management previously said optics should complement and eventually displace copper in scale-up networks. That shift supports the bullish case, but the latest EPS figure shows that demand growth must translate into dependable earnings.
What COHR’s Analyst Targets Mean After the Earnings Reaction
Analyst actions on Aug. 13 were broadly supportive. Raymond James raised its price target to $448 from $435 and kept a Strong Buy rating. Jefferies raised its target to $420 from $375 while keeping its Buy rating. Needham also set a $420 target and retained Buy.
The analyst consensus was Buy, with 23 Buy ratings, 6 Holds, and no Sell ratings. The consensus target was $389, with a median of $420, a high of $455, and a low of $230. Those targets show that analysts still value Coherent’s AI optics exposure, even after the earnings-driven decline.
News sentiment also remained strongly positive. COHR’s seven-day sentiment score was 0.8999, while its 30-day score was 0.8758 and its 90-day score was 0.8313. The stable trend suggests the selloff reflects a sharp earnings reset rather than a broad collapse in the company’s market narrative.
For investors, the practical takeaway is discipline. A 6.56% drop alone does not establish a bargain, especially with a 155.98 P/E. The stronger case for a contrarian entry rests on the $1.81 billion Q3 revenue base, the NVIDIA partnership, and continued AI networking demand. The main risk is that the $0.74 EPS result signals pressure that the growth story has not absorbed.
Why Coherent’s Earnings Drop Matters for Investors
COHR drops today because a high-expectation AI optics stock met a major earnings test with a $0.74 EPS result against a $1.43 estimate. Coherent still owns valuable exposure to optical networking, NVIDIA, and co-packaged optics, but its premium valuation demands cleaner earnings execution. The stock’s next investment decision should separate durable demand from the price investors already paid for it.
COHR is down because investors reacted to Coherent’s fiscal Q4 earnings announcement, where EPS came in well below estimates. The miss triggered a sell-the-news move in a stock that had already priced in strong AI infrastructure growth.
+Should I buy COHR stock now?
Not on the drop alone. The stock still has strong AI optics exposure, but its premium valuation means investors should wait for clearer earnings execution before treating this as a low-risk entry.
+Did Coherent miss earnings?
Yes. Coherent reported quarterly EPS of $0.74 versus an estimate of $1.43, a large negative surprise. That miss was the main catalyst behind the stock’s decline.
+Is Coherent still a long-term AI stock?
Yes, the long-term thesis is still intact because Coherent has exposure to optical networking, data-center infrastructure, and a partnership with NVIDIA. But the latest earnings show investors need proof that demand is translating into stronger profits.
