Key Highlights

  • Coherent (NYSE:COHR) is scheduled to report first-quarter fiscal 2027 results on Wednesday, November 4, 2026 after the close, with a call at 4:30 p.m. ET, and Options data implied a move of about 16%.
  • Fourth-quarter fiscal 2026 Revenue was USD 2.05 billion, up 34%, with non-GAAP Earnings of USD 1.74 per share and a non-GAAP gross Margin of 40.2%, according to the August 12, 2026 release.
  • First-quarter guidance calls for revenue of USD 2.2 billion to USD 2.4 billion, non-GAAP earnings of USD 1.85 to USD 2.05 per share and a non-GAAP gross margin of 39.5% to 41.5%.
  • Full-year fiscal 2026 revenue was USD 7.12 billion, up 22.5% from USD 5.81 billion, with non-GAAP Earnings Per Share of USD 5.61 and GAAP earnings per share of USD 4.12.

What the Guide Implies

Coherent (NYSE:COHR) makes lasers, transceivers and other optical parts used in data centre networks. The first-quarter revenue guide of USD 2.2 billion to USD 2.4 billion has a midpoint of USD 2.3 billion, about 12% above the USD 2.05 billion posted in the fourth quarter, simple arithmetic on two published numbers. Non-GAAP operating expenses are guided to USD 400 million to USD 420 million and the non-GAAP tax rate to 18% to 20%. Per published call coverage, management is targeting its first quarter above USD 3 billion of revenue during fiscal 2027, which would be a further step up from the USD 2.05 billion posted in the fourth quarter and from USD 2.3 billion at the guide midpoint.

GAAP Versus Non-GAAP

The headline gap between fourth-quarter GAAP earnings of USD 1.19 per share and non-GAAP earnings of USD 1.74 per share shows how much adjustment sits in the numbers, with gross margin at 38.5% on a GAAP basis and 40.2% non-GAAP. Calendar consensus of USD 1.78 per share is below the low end of the USD 1.85 to USD 2.05 guide, which suggests that it rests on a different basis or an older estimate. Investors should compare the reported figure with the company's own guide and note which basis analysts use. The company reports in a fiscal year ending in June, so the first quarter covers July to September 2026.

Risks and What to Watch

Traders will watch revenue against the USD 2.2 billion to USD 2.4 billion range, gross margin against 39.5% to 41.5%, and commentary on supply, customer concentration and new optical technologies. Supplier shares can also fall when a customer pauses orders, even if long-term Demand is intact. Risks include reliance on a small group of AI data centre customers, pricing pressure from rivals, capacity constraints and the sensitivity of supplier shares to any hint that cloud spending is slowing. A 16% implied move is a snapshot from options data on October 30, not a forecast of direction. Nothing in this article is Investment advice.

Where Things Stand

The answer is Coherent (NYSE:COHR), whose USD 2.2 billion to USD 2.4 billion revenue guide and 34% growth help explain a 16% options-implied move. The report on November 4, 2026 after the close should show whether sales reached the guide, whether the gross margin held near 40% and whether management still sees a path to a USD 3 billion quarter. A shortfall or cautious tone could matter more than a modest beat.
