COHR stock is moving lower in after-hours trading following the release of strong Q4 earnings and upbeat guidance, with shares down approximately 5% despite outperforming expectations. The stock opened with a 5.3% gap up after the prior close of $328.57 but has since pulled back to $339.46. The pullback appears to reflect profit-taking after a sharp post-earnings rally and a broader market reassessment of valuation.
What Happened
Coherent Corp. reported Q4 FY2026 results that exceeded expectations, with revenue of $2.05 billion, a 34% year-over-year increase and 42% on a pro forma basis. Non-GAAP gross margin reached 40%, up from 38.5% in the prior year. The company also provided strong guidance for Q1 2027, forecasting adjusted earnings per share of $1.85 to $2.05 and revenue of $2.2 billion to $2.4 billion. The CEO highlighted "exceptional" demand for optical networking technology driven by AI infrastructure growth. The results were disclosed in a Form 8-K filing and accompanied by a slide deck published by the company. Despite the strong numbers, the stock has fallen 5% in after-hours trading.
What The Data Shows
The stock opened at $346.00 and reached an intraday high of $380.99 before retreating to a low of $327.08. Volume has reached 9.8 million shares, or 1.7 times the 3-month daily average. The 52-week range is $84.35 to $440.00, with the current price near the lower end of that range. The P/E ratio stands at 143.9, and the stock has a beta of 2.11, indicating higher volatility relative to the market.
