China's already-shipping CW lasers make Sivers' Chinese pluggable pipeline depend on price and qualification speed. Yuanjie says its 70/100mW chips, the classes Sivers lists, are in continuous large-volume delivery. It guides Q3 revenue up 265-293% and expects new capacity from end-2026 to early 2027, before Sivers' Q4 2027 Glasgow expansion. Yuanjie's 120/300/400mW parts remain in customer validation; Western hyperscaler qualification is probably where Sivers still has time. x.com  x.com  x.com  … Show more

Sivers Semiconductors is expensive because its valuation rests on a $1.2 billion opportunity pipeline, an unreliable KPI. At 15% conversion next year, it trades near 22x 2027 sales versus Lumentum's 14x and Coherent's and AAOI's 5x, and about 13x 2029 sales versus 3-9x for incumbents with contracted LTAs. The InP laser shortage is Lumentum's and Coherent's asset; Sivers gains access only in H2 2027 if all goes to plan and needs the shortage into 2028. It is a swing trade, not a conviction hold. … Show more

Optics and photonics should be among AI's biggest winners as faster GPU networks need optical connections that suppliers cannot expand quickly enough. Lumentum says some components are sold out through early 2029; Sivers is investing $30M to target more than 100M lasers a year, with operations expected in Q4 2027. Potential US restrictions on Chinese transceivers could reshape supply in 2027. Applied Optoelectronics and Sivers are the favorites. x.com  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' $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 

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 was turned into something bigger than it was, is, or probably ever will be by market hype, not by management. Management never really tried to pump the stock and kept mmWave and lidar, the most operationally relevant businesses, at the center of its reporting; the opportunity-pipeline story emerged only once share-price pressure became extreme. The Glasgow expansion replaces outdated capacity but costs money upfront and will take a while to generate meaningful revenue. … Show more

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 is less exposed to tighter AI financing because its 700M SEK raise funds a buildout largely reliant on external foundries. It is qualifying with Ayar, Jabil, GlobalFoundries and O-Net for potential tier-one hyperscaler pluggable, CPO and NPO deployments. Higher rates may strain neoclouds needing billions for GPUs, but optical content and aggregate demand should still rise even if hyperscaler AI capex falls, especially as new players start qualification. x.com 

Rising 1.6T switching demand favors optical suppliers, though their execution risks vary. Bank of America says the market could grow ~101% annually through 2030. Marvell's leading DSPs and Lumentum's supply-short 200G EML lasers are lowest risk; Applied Optoelectronics' capacity expansion and Fabrinet's customer concentration make them medium risk. Aeluma remains pre-commercial, while Lightwave Logic's polymer modulators are a high-risk moonshot despite its TSM partnership. x.com
