Thesis
The theme capitalizes on the accelerating demand for photonic equipment and materials driven by AI data center expansion and the transition to co-packaged optics (CPO). Infrastructure bottlenecks and underinvestment create significant opportunities for upstream suppliers, despite cyclical headwinds in some legacy markets.
Bull case
Explosive AI-driven demand for optical interconnects, both pluggable and CPO, is creating an unprecedented need for bandwidth and power efficiency in data centers, driving massive capital expenditures into the photonics supply chain.
The fundamental shift from electrical to optical interconnects, particularly the transition to Co-Packaged Optics (CPO) and Silicon Photonics (SiPh), necessitates new components, substrates, and specialized manufacturing equipment, creating a structural growth driver for the photonics equipment theme.
Supply chain bottlenecks and years of underinvestment in critical photonic materials (e.g., InP crystals, SOI wafers) and equipment (e.g., MOCVD tools, wafer bonding) are leading to scarcity and pricing power for key "picks and shovels" suppliers.
Bear case
Some early winners in the optical interconnect space are becoming "priced for perfection," suggesting limited upside and potential for profit-taking, as the market fully appreciates their near-term growth, shifting focus to less crowded segments.
The exact timing and pace of widespread Co-Packaged Optics (CPO) adoption remain uncertain, with industry leaders expressing caution about immediate mass deployment, which could delay revenue ramps for companies heavily invested in CPO-specific technologies.
Many photonics equipment and material suppliers are diversified companies with significant exposure to cyclical end markets like consumer electronics and automotive, where downturns can obscure or offset the growth from photonics, leading to market mispricing and volatility.

| ASM.AS_3670bd7b | Expected ramp in 2026 and 2027 | 2026-01-01 | 2027-12-31 | Ramping of new Epi and ALD dipole/work-function design wins for HBM-related DRAM (ASM noted new wins that are expected to ramp in 2026–2027). | Successful 2026–2027 ramp would increase ASM's share in the DRAM/HBM market, lift equipment revenue and aftermarket services and support margin expansion; slower ramp or losses of design-wins would reduce the projected SAM gains and delay revenue/margin benefits. | Ticker | 2025-10-29 | earnings_transcript | ASM.AS (ticker) |
| ASM.AS_24a89650 | Q4 2025 bottoming; quarterly orders to pick up as 2026 progresses | 2025-10-01 | 2026-12-31 | Management's expectation that order intake will bottom in Q4 2025 at a slightly higher level than Q3 and then progressively recover through 2026. | If orders indeed bottom in Q4 and resume sequential growth in 2026, revenue visibility and investor sentiment would improve and support the company's 2026 growth outlook; if orders fail to recover, revenue guidance, backlog conversion and valuation could come under pressure. | Ticker | 2025-10-29 | earnings_transcript | ASM.AS (ticker) |
