SIVERS SEMICONDUCTORS - FOUNDRY-STACK CAPACITY OPTION IN AI OPTICS

WHAT THIS NOTE SAYS

This report argues that Sivers has moved from being viewed as a standalone InP fab to a designed-in light-source layer inside the AI datacenter optics stack, with the June 2, 2026 GlobalFoundries collaboration as the key catalyst that changes the quality of the story.
SEQH frames the new value not as a firm contract but as a capacity option, then adds that option layer plus a pipeline-conversion layer to prior Sivers work and arrives at a platform value around SEK 150, versus a spot price of SEK 86.45.

Core thesis

The central idea is that being embedded in a tier-one foundry’s silicon-photonics reference designs can pre-qualify Sivers for future CPO and LPO volume without Sivers having to fund the foundry capex itself.
SEQH stresses that the GlobalFoundries arrangement carries no disclosed volume, revenue, or exclusivity commitments, so the correct valuation frame is not backlog but a real option on future foundry-scale optical-engine volume.
The note says this does not replace the earlier Sivers thesis around InP scarcity and sovereignty, but extends it by adding a Foundry-Stack Capacity Option and a pipeline-conversion uplift.

In silicon photonics, silicon can modulate and route light, but it still needs a III-V laser source, usually indium phosphide, supplied from outside the silicon die.
As optics move from pluggables toward co-packaged optics, the external light source becomes a qualified part of the foundry reference design, and that is exactly the layer where Sivers sits.
SEQH highlights GlobalFoundries as the most important anchor because it is presented as one of the largest pure-play silicon-photonics foundries, with photonics revenue moving from about 200 million dollars in 2025 toward 400 million dollars in 2026 and a 1 billion dollar run-rate exiting 2028.

The rerating is framed as cumulative rather than single-event. SEQH’s ledger includes ESA SATCOM, U.S. defense mmWave, a LiDAR ramp, O-Net and Enablence 8-channel ELS, Jabil 1.6T LRO, the POET collaboration, the Ayar Labs 16-wavelength WDM path, and finally the GlobalFoundries SiPh / SCALE embed.
The key pattern is that the wins now span defense, space, LiDAR, pluggable optics, and CPO, which reduces reliance on any one program and broadens the platform narrative.
At the same time, SEQH is careful to note that these are still mostly design wins and qualification events, not committed-volume supply contracts, which is why the valuation uses risk-weighted conversion assumptions.

SEQH sizes the light-source slice by starting from large optical TAMs, including 50 billion dollars plus for pluggable optics, 73 to 100 billion dollars for AI-cluster optics, 4.7 to 15 billion dollars for CPO hardware, and 1.5 billion dollars plus per year for ELSFP laser modules.
Applying a 10 to 15 percent laser-content share to those module markets, the note estimates roughly 8 billion dollars of addressable laser and ELS content by 2030 that could sit within a tier-one foundry stack.
Method 1, the sum-of-layers capacity-option build, starts from a rebased prior platform core of SEK 36.7 per share, then adds SEK 102.8 for the Foundry-Stack Capacity Option and SEK 14.0 for pipeline conversion, reaching SEK 153.
Method 2, the forward EV/Sales peer cross-check, gives SEK 129 using a 2028 revenue anchor and SEK 150 using a 2030 revenue anchor, so the triangulated range comes out to roughly SEK 144 to 150, which is why SEQH frames the platform value at about SEK 150.

The dominant valuation layer assumes that of the 8 billion dollar 2030 light-source pool, Sivers can capture about 9.5 percent share with a 55 percent probability that designed-in positions convert into actual volume.
That produces about 418 million dollars of option-case revenue, which SEQH capitalizes at a discounted forward 10x EV/Sales to derive the largest single piece of the valuation.
The separate pipeline-conversion layer uses the 799 million dollar opportunity pipeline, an 18 percent blended win rate, and a 35 percent durable-revenue annualization, deliberately kept modest to avoid double counting the larger capacity option.

On the financial side, FY2025 revenue was SEK 304.1 million, gross margin was 87.2 percent, operating income was SEK -141.3 million, and net income was SEK -186.5 million, showing that the company still sits firmly in an investment phase.
Q1 2026 sales were SEK 61.9 million, down 22 percent year over year, while the opportunity pipeline expanded to about 799 million dollars, up 77 percent year to date.
SEQH also flags material overhangs: the stock has risen roughly 28-fold from its February low, the valuation implies extreme future-scale assumptions, losses are widening, and the note explicitly highlights short-seller pressure, market-conduct scrutiny, governance risk, dilution risk, and competitive displacement as real threats to the thesis
In SEQH’s own downside framing, if flagship platforms slip, GF ramps move out, financing becomes punitive, or governance confidence is impaired, the valuation could compress back toward the SEK 37 to 60 commercial core range.

The conclusion is that Sivers now deserves to be analyzed less as a niche component maker and more as a levered option on foundry-scale AI optics volume, because being designed into the stack is strategically better than simply selling merchant laser arrays.
But SEQH is explicit that SEK 150 is a contingent platform value, not a recommendation and not a contract-backed base case, so the upside case depends heavily on whether those designed-in positions actually convert into durable volume over 2027 to 2030.
