Growth Outlook
The key drivers leading Lumentum's growth are as follows:.
- Explosion in Demand for Optical in AI Data Centers: Structural growth in demand for optical transceivers and OCS driven by accelerated investment in hyperscale AI infrastructure
- NVIDIA Strategic Partnership: NVIDIA’s $2 Billion (approx. 2.961 trillion KRW) Investment in Advanced Optics — Securing Multi-Year Revenue Visibility
- Sold Out Through 2027 CEO Michael Hurlston Officially Confirms Strengthening Pricing Power Amid Supply Constraints
- Commercialization of OCS (Optical Circuit Switch): Starting from the second half of 2026, OCS-related optical communication revenue is expected to contribute $400M+ (approx. 592.2 billion KRW).
- Co-Packaged Optics (CPO): Preempting the demand for next-generation high-bandwidth optical connections
Bank of America forecasts that the AI optics market will grow to $1.49 billion (approximately 133 trillion won) by 2030.

12-Month Target Price Scenario
Current Stock Price: $846.89 (approx. 1,253,835 KRW)
| scenario | Target price | Converted to Korean Won | Expected rate of return | Probability |
|---|---|---|---|---|
| Base Case | $950 | Approximately 1,406,485 won | +12.2% | 50% |
| Bull Case | $1,225 | Approximately 1,813,625 won | +44.6% | 25% |
| Bear Case | $550 | Approximately 814,281 won | -35.1% | 25% |
| Weighted expected rate of return | – | – | +8.5% | – |
Base Case: We reflect the annualization of the Q3 FY2026 median guidance of $805M and the continued expansion of operating leverage.
Bull Case: This applies when the early full-scale realization of OCS demand, the expansion of the NVIDIA contract size, and the effects of index inclusion are realized.
Bear Case: This is a scenario involving a temporary slowdown in the AI investment cycle, increased debt burden, or intensified competition.
Recent major issues
1. NVIDIA Multi-year Contract Signed (March–April 2026)
NVIDIA announced a $2 billion (approximately 2.961 trillion won) investment in advanced optics in Lumentum.
Along with the signing of a strategic partnership for indium phosphide (InP)-based AI data center optical devices, plans were also announced to build a new 240,000 sq ft production facility in Greensboro, North Carolina.
2. Large-scale OCS order (March 2026)
We have signed a multi-billion dollar multi-year OCS (Optical Circuit Switch) contract with a hyperscale customer.
From the second half of 2026, a contribution of over $400M (approx. 592.2 billion KRW) in optical communication revenue is expected.
3. Official Confirmation of “Orders Secured by 2027” (April 10, 2026)
CEO Michael Hurlston officially confirmed in a Bloomberg interview that orders are “sold out until 2027 to the point where we cannot keep up with demand.”.
Subsequently, Aletheia Capital significantly raised its target price from 1 TP 4 T 500 to 1 TP 4 T 1,225.
Risk factors
- High debt leverage: D/E 392.51 TP 3T, Total Debt 1 TP 4T 3.32B (approx. 4.9188 trillion KRW). Risk of increased interest burden due to changes in the interest rate environment.
- Overheated Valuations: With high absolute valuations such as a P/S of 28.7x and EV/EBITDA of 234x, there is a possibility of a significant correction if earnings expectations are not met.
- Supply Chain Concentration Risk: Indium Phosphate (InP) material and high concentration on specific customers (NVIDIA, Hyperscale)
- Intensifying competition: Increased entry of competitors such as Coherent (COHR) into the AI optics market
- AI Investment Cycle Risks: Growth story could be damaged if AI data center investment slows or expectations for AI demand are adjusted.
Final Investment Opinion
Investment Opinion: BUY | Conviction: Medium | Investment Period: 12 Months
Lumentum possesses exceptional growth momentum as a core supplier of AI optical infrastructure.
Strong demand visibility, including the NVIDIA partnership, large-scale OCS orders, and the completion of orders by 2027, supports the fundamentals.
However, since the valuation after a 52-week rise of +1,3111 TP3T is largely already priced in, the extent of further gains depends on whether earnings can be sustained.
It is appropriate for existing holders to maintain their positions, while new investors should approach this with a dollar-cost averaging strategy.
