Sivers Semiconductors is still a startup, not a volume supplier, until it announces purchase orders with clear amounts and gives year-by-year revenue guidance. Its growing opportunity pipeline rests on management's discretion, not contracts, so it is noise. Management dodged forward guidance, reported no qualifications or production orders while CPO should grow triple digits, and conceded it trails Lumentum everywhere. Its margin target would be remarkable versus Coherent's ~40%. x.com 

Sivers Semiconductors' break-even hurdle puts market expectations far beyond what it can realistically deliver in the next 12 months. Revenue would need to multiply several times just to break even, before further R&D or foundry expansion spending. Its recent cash raise means near-term dilution is not expected, but much of the cash will go toward the foundry as quarterly losses continue. Hype could still lift the stock without improving the fundamentals, leaving huge short-term risk. x.com  x.com 

Sivers Semiconductors is crossing from an engineering and NRE model to a product-led component model, a shift that earns very different multiples. FY2025 revenue rose 25% to SEK304.1m, product revenue reached SEK85.7m (about 28% of sales), and it entered 2026 with a $453m non-binding pipeline. Wireless is the nearer-term, more de-risked engine; photonics for AI interconnects carries larger long-duration upside. The risk is that losses and negative cash flow dilute equity before products scale. … Show more

Sivers Semiconductors' AI optics rally prices in more than its photonics business has shown. About 75% of revenue is still wireless mmWave. Its 50-75mW CW lasers suit 400G and 800G but trail tier-1 rivals, making it a tier-2 spillover supplier like Applied Optoelectronics. Its small, old Glasgow fab has $50-150 million of potential laser revenue, with no sign of major expansion. Its multi-wavelength laser arrays for CPO are pre-revenue as Nvidia and Broadcom build their own. x.com 

Sivers Semiconductors' valuation is hard to justify even on its most ambitious targets for the next 1-3 years, given the margins it has and will have. Its most interesting angle is private companies such as Lightmatter apparently using its CW laser arrays, though that is not officially confirmed. Lumentum and Coherent, while not exact peers, are preferred. x.com 

Sivers Semiconductors is undervalued because its photonics subsidiary's valuation potential is likely grossly mispriced, though that unit deserves a hefty discount until listed. Sivers Photonics failed to list via a SPAC in 2024, even early in the AI boom; the main wireless business is boring; and unlisted subsidiaries trade at deep discounts until holders see a path to monetization. Per @aleabitoreddit, Sivers, a laser maker for hyperscaler photonic supply chains, is valued at only about $200M. … Show more

Sivers Semiconductors looks fairly valued even on generous assumptions, offering perhaps 100% upside over 3-4 years, which is not compelling. Even $200 million of revenue, 30% EBITDA margins and an 18x multiple gives about a $1.1 billion market cap, while a needed $65-100 million raise lifts today's $430 million to about $530 million. Management's deck implies $100 million of 2029 revenue at a 25% margin, about 21x 2029 EBITDA after a raise, not cheap unless revenue hits $600-800 million. x.com  … Show more

Sivers Semiconductors' management is letting a generational InP bottleneck pass it by. Burning cash on incremental fab tweaks keeps it just a laser vendor, and the call gave generic evasions on the two metrics that move the stock: its six pluggable engagements and foundry allocations. The CFO's hedging on a US dual listing shows timid complacency that will keep Sivers priced like a sleepy European component supplier rather than a high-multiple tech engine like SK hynix or ASML. x.com 

Aeva's move into NPO/CPO is highly bullish for Sivers, again at the center of photonics through its CW-DFB lasers. Sivers is regarded as Aeva's laser supplier, and Aeva signed a joint development deal with an optical engine maker for a major hyperscaler, deploying in 2H27 and ramping in 2028. Per @ParadisLabs, Sivers partner GlobalFoundries expects silicon photonics revenue to more than double in 2026, with NPO ramping in 2027 and CPO in 2028. Jane Street closed its Sivers short. x.com  x.com  … Show more

Sivers Semiconductors' $30M expansion of its Glasgow InP fab, targeting over 100M CW DFB lasers a year by Q4 2027, likely means hard dilution. As @PhotonCap notes, the plan shifts Sivers toward hybrid manufacturing, and its capacity target and customer ramps remain forward-looking rather than committed volumes. x.com
