Q2 2026

Date: 2026-02-04Rank: #46Forward Promise: very_bullish

Coherent reported Q2 revenue of $1.69 billion, up 9% sequentially and 22% year-over-year on a pro forma basis, driven by a 14% sequential surge in Data Center revenue. Non-GAAP EPS grew 35% year-over-year to $1.29, supported by a 77 basis point expansion in gross margin to 39%. The company highlighted extraordinary demand visibility with a book-to-bill ratio exceeding 4x in Data Center, fueled by 800G and 1.6T transceiver ramps. Management raised guidance for Q3, projecting revenue between $1.7 billion and $1.84 billion, and indicated that fiscal 2027 revenue growth will exceed fiscal 2026 levels due to AI infrastructure build-outs and new product ramps like OCS and CPO.

Management Tone

Management displayed a high degree of confidence and urgency throughout the call, emphasizing 'extraordinary' demand visibility and 'step function' increases in bookings. The tone shifted from detailing strong execution in the prepared remarks to a highly assertive stance in Q&A, where they aggressively defended their capacity expansion plans and market positioning against skepticism regarding supply equilibrium.

Confidence: HIGH

Strategic Signals

Management is aggressively pivoting the company toward AI data center infrastructure, which now accounts for over 70% of revenue. The strategic emphasis is on vertical integration, specifically the ramp of six-inch indium phosphide production. This technology provides a significant cost advantage—producing more than four times as many chips at less than half the cost compared to three-inch wafers—positioning Coherent to capture market share and expand margins as 1.6T transceiver demand accelerates.

The company secured a 'massive' design win for Co-Packaged Optics (CPO) with a leading AI customer, leveraging its high-power CW lasers manufactured in the US. This signals a strategic shift beyond pluggable optics into higher-value, integrated solutions for scale-up architectures. Management views CPO in scale-up as an 'orders of magnitude larger' incremental TAM opportunity, suggesting a long-term growth driver that will materialize in late 2026 and beyond.

Operational streamlining remains a priority, evidenced by the divestiture of the Munich product division and the closure of 33 sites over six quarters. This portfolio optimization is immediately accretive to margins and EPS, allowing management to redirect capital toward high-growth areas like Data Center and Communications. The focus on driving SG&A below 10% and targeting 8% indicates a disciplined approach to capital allocation.

Coherent is expanding its manufacturing footprint geographically, adding capacity in Malaysia and Vietnam, while emphasizing US-based production in Sherman, Texas. This 'China-plus-one' strategy is resonating with customers, as evidenced by the Apple partnership and the CPO design win, both of which specifically cited US manufacturing as a key decision factor. This diversification mitigates supply chain risk and aligns with geopolitical trends.

Bottom Line

Price Target: N/A

Coherent is executing flawlessly in the sweet spot of the AI infrastructure build-out. The transition to 6-inch Indium Phosphide provides a defensible moat and significant operating leverage, driving gross margins toward 42%. With a book-to-bill exceeding 4x and 2026 largely booked, the visibility is exceptional. The company is successfully pivoting from a diversified industrial player to a high-growth optical component leader, with new growth vectors like CPO and OCS just beginning to contribute. The risk of an oversupply cycle appears muted for at least the next 18-24 months, providing a clear runway for re-rating.

Forward Promise

Overall: 8.5 · very_bullish

Exceptional visibility and execution justify confidence in sustained hyper-growth.

Management provided concrete evidence (wafer starts, backlog) that supports their bullish outlook. The Q&A removed doubts about their ability to execute on the capacity ramp, confirming a very strong near-term trajectory.

Red Flags

While demand is currently extraordinary, management acknowledged that external input costs for components like EMLs are rising. Although they claim this is offset by internal capacity, the reliance on external suppliers for a portion of the indium phosphide supply chain introduces a risk if cost inflation outpaces their ability to pass it on or if internal ramp delays occur.

The Industrial segment remains a weak point, with revenue flat year-over-year. While management points to a pickup in semi-cap orders, the broad-based industrial recovery is described as 'too early to call,' suggesting that the non-AI portions of the business are not yet contributing to growth and remain a drag on overall company performance compared to the hyper-growth in Data Center.

Capital expenditures are rising significantly ($154M in Q2 vs $106M Y/Y) to support capacity expansion. While necessary to meet demand, this heavy reinvestment creates execution risk. Any hiccup in the six-inch indium phosphide yield or ramp speed could result in supply constraints or margin pressure, given the aggressive 80% wafer start targets already being hit.

Management's guidance relies heavily on the assumption that supply-demand imbalances will persist for years. If competitors ramp capacity faster than anticipated or if AI capex slows, the industry could face oversupply. Management's dismissal of equilibrium until at least 2028 is a bullish forecast that carries substantial risk if the cycle turns.

Macro Insights

AI Infrastructure: AI data center build-outs are driving a 'step function' increase in demand for optical components, specifically 800G and 1.6T transceivers, with no sign of slowing through 2027.

Semiconductor Capital Equipment: Orders from semi-cap customers increased significantly in Q2, signaling a recovery in the industrial segment driven by investments in chip manufacturing capacity.

Supply Chain: The industry faces a structural shortage of Indium Phosphide capacity that is expected to persist through at least 2027, creating a seller's market for laser components.
