Shares of Coherent (COHR) closed Wednesday’s regular session up 8.2% at $355.64, only to retreat approximately 4% to around $343.81 in after-hours trading. The decline followed the company’s announcement of record-breaking fiscal fourth-quarter results that exceeded analyst projections.
Fourth-quarter revenue reached $2.05 billion, representing a 34% year-over-year increase and surpassing the $1.98 billion consensus estimate. Adjusted earnings of $1.74 per share topped the $1.62 analyst forecast and marked a significant improvement from $1.00 in the prior-year period.
For the complete fiscal 2026 year, Coherent generated $7.12 billion in revenue with non-GAAP earnings per share of $5.61, reflecting approximately 59% bottom-line growth versus the previous year. Chief Executive Jim Anderson described the performance as “an outstanding year” featuring record-setting revenue and improved profitability margins.
The company’s outlook for Q1 fiscal 2027 also exceeded expectations. Management projected revenue between $2.2 billion and $2.4 billion with adjusted earnings ranging from $1.85 to $2.05 per share. The Street had anticipated $2.14 billion in revenue and $1.77 in earnings.
Anderson highlighted the ongoing transition in data centers away from traditional copper connections toward optical technology, a shift benefiting Coherent’s product portfolio. “We enter fiscal 2027 with exceptional customer demand, expanding production capacity, and multiple new growth platforms beginning to ramp,” the CEO stated.
What Triggered the After-Hours Decline?
Despite the impressive results, COHR retreated in extended trading. The explanation is relatively simple: positive expectations were already reflected in the share price.
Shares had experienced a substantial pre-earnings rally, partially fueled by encouraging results from optical networking competitor Lumentum Holdings. Lumentum exceeded its Q4 projections on Tuesday and provided above-consensus Q1 guidance, offering investors an early indication of Coherent’s likely performance.
Options pricing suggested an expected move of nearly 15% surrounding the earnings announcement. After the results confirmed expectations, numerous investors who had established positions ahead of the report took profits.
Premium Valuation Limited Upside Potential
COHR currently commands a forward price-to-earnings multiple of approximately 39, elevated from roughly 25 times twelve months ago. This expanded valuation left minimal opportunity for additional gains, despite results exceeding expectations across all major metrics.
Lumentum, valued at 41 times forward earnings, declined 0.4% in after-hours activity following its own robust quarterly report released Tuesday.
The broader equity market provided limited additional momentum. Both the S&P 500 and Nasdaq concluded Wednesday’s session relatively unchanged, supported by benign July consumer price data. Inflation increased just 0.1% on a monthly basis and 3.4% annually, matching forecasts. This macroeconomic backdrop had already been digested during regular trading.
Coherent shares have surged more than 200% over the trailing twelve-month period.
