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.comÂ
Sivers is a tier-three company with no mass production capacity of its own, always dependent on external foundries, and the real danger is Lumentum beating it with higher-quality WDM lasers. @vikramskr notes that both ultra-high-power and wavelength-multiplexed lasers are valid approaches for co-packaged optics, so the WDM choice itself is not the problem. On the other side, Sivers says more laser capacity is being added on top of Win Semi, with more partners being developed. x.com x.comÂ
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.comÂ
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
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.comÂ
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.comÂ
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.comÂ
Sivers Semiconductors' LiDAR design win is closer to generating revenue now that its customer has placed initial production orders. Shipments begin in Q4 2026; automotive and industrial programs target 2027 production. Sivers estimates $53M-$138M in lifetime revenue potential, not firm backlog; the initial order value is undisclosed and the program was announced in March. Repeat orders and shipment growth must convert potential into revenue; the market also wants profitability. x.com x.comÂ
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
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.comÂ
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
