Nvidia's $2B Investment Boosts Coherent Stock, But DeepValue Report Cautions on Execution Risks

What happened

Nvidia announced a $2 billion investment in Coherent and Lumentum to secure optical networking capacity for AI infrastructure, sending their stocks higher. This news reinforces the AI optics demand narrative that has driven COHR's stock up 133% over the past year, as highlighted in the DeepValue report. However, the report emphasizes that COHR's valuation already prices in strong demand, with forward returns hinging on shipment conversion from record bookings rather than headlines. The Nvidia investment may provide capital for capacity expansion, but it does not guarantee that COHR will successfully ramp indium phosphide production or achieve the required double-digit sequential datacenter growth. Investors should look beyond the positive sentiment and focus on the upcoming March and June 2026 quarters for proof of execution, as any shortfall could trigger significant downside.

Implication

Nvidia's $2 billion infusion validates AI optics demand and could aid COHR's capacity build-out, but it doesn't resolve the critical InP bottleneck or ensure timely revenue conversion. With the stock priced at a premium (EV/EBITDA 32.4, P/E 131), any miss in the guided double-digit sequential datacenter growth for March or June 2026 could lead to a sharp correction. The DeepValue report's 'WAIT' rating and attractive entry at $175 suggest better risk-reward after a pullback, given the crowded narrative and high execution risk. Investors should monitor COHR's ability to double internal InP capacity by Q4 CY2026 and sustain growth, as sentiment-driven rallies often overlook operational realities. Ultimately, this news is a bullish signal on demand but does not alter the need for concrete proof of shipment conversion in the next two quarters.

Thesis delta

The Nvidia investment strengthens the demand-side narrative for AI optics, potentially accelerating COHR's capacity expansion with additional capital. However, it does not materially change the investment thesis, which remains centered on COHR's ability to convert bookings into revenue through successful InP ramp and assembly scaling. Therefore, the core recommendation to wait for proof points in the upcoming March and June 2026 quarters stands unchanged.
