Simplify's take

What believers are saying

  • November 6, 2026 Q1 revenue implied Q2 growth above 30%, driven by Photonics-SOI.
  • BofA October 9, 2026 raised target to €300, betting on photonics demand.
  • Convertible bonds and July 29 buyback signal management's confidence and financing flexibility.

What critics are saying

  • Mobile RF-SOI demand remains weak, and JPMorgan cut expectations on inventory digestion.
  • Soitec spent €500 million on convertibles, adding leverage if photonics ramps disappoint.
  • A 2027 AI capex slowdown would collapse photonics orders and crush valuation.

What makes Soitec unique

  • October 2026 Singapore fab qualification makes Soitec the only scaled 300mm Photonics-SOI supplier.
  • Reuters August 31, 2026: over ten take-or-pay contracts lock demand and pricing.
  • Smart Cut and 95% photonics substrate share create a moat in advanced wafers.

Soitec shares surge 371.7% this year, but 7.1x price-to-sales looks stretched against 4.0x peers

Soitec's shares have risen about 371.7% this year, raising the question of whether its sales justify the price. European chip stocks, including Soitec, have recently come under pressure over concerns about the financial sustainability of AI infrastructure spending. The French chipmaker trades at a price-to-sales ratio of 7.1x, well above the semiconductor industry average of 4.0x and a peer group average of about 4.0x. A Fair Ratio model that weighs growth, margins, scale, and risk points to a lower level, so the stock looks overvalued on this measure. Views are split. Bulls see the stock 29% undervalued, citing diversification into automotive, photonics, power electronics, and AI. Bears call it 113% overvalued, pointing to a 30% revenue fall, a gross margin of 16.3%, and impairments.

Scaling infrastructure, all-in on NPO, and a "material-rich" road map: Themes and takeaways from Soitec's 2026 Silicon Photonics Workshop.

Scaling infrastructure, all-in on NPO, and a "material-rich" road map: Themes and takeaways from Soitec's 2026 Silicon Photonics Workshop. October 22, 2026 - By Jake Saltzman, photonics.com With its 2026 forecast, photonics market research firm LightCounting is projecting a roughly-10x increase in shipments of silicon-based pluggable modules from 2024's projected total. As industry strives to meet demand, silicon photonics is fortifying its position as a critical enabling technology both for the scale-up, as well as the sector's next innovation era, shaped by a transition from front-panel pluggables to advanced interconnect architectures. Yet the challenges imparted by surging AI workloads and networking infrastructure are highly dynamic. For one, the notion of scaling in this vibrant technology environment envelops the entire industry value chain. This means multiple, distinct bottlenecks and potential chokepoints. As a result, progress is iterative. Fixed-date deployments - specifically, for co-packaged optics (CPO) - are crucial stepping-stones on the road to streamlined productization and the ultimate goal of getting product to end-users. But meeting such a goal on time and via repeatable processes will necessitate hitting new benchmarks, particularly in testing and packaging. Both present unique obstacles.

The latest analyst catalyst came on October 9, 2026, when Ideal Investor reported that Bank of America upgraded Soitec from Neutral to Buy and set a EUR 300.00 price target. Discover more Invest in Stocks Bank of America bets on photonics. The upgrade is tied to Soitec's exposure to silicon photonics, a technology used for high-speed optical data transmission in data centers. Bank of America expects optical port requirements to grow faster than AI processor volumes and sees capacity expansion as a potential next step. The target is well above the Lang & Schwarz quote, but the article does not establish a causal link between the analyst action and the October 20 price. That distinction matters because valuation expectations and operating delivery now pull in opposite directions. What do the revenue figures show?

Soitec jumps 7% as BofA upgrades to buy on silicon photonics demand, eyes $790M Singapore expansion

Shares of French chip materials maker Soitec jumped 7% in Paris on Friday after BofA Securities upgraded the stock to "buy" from "neutral" and raised its price target to €300 from €152. BofA cited Soitec's over 90% share of the key material used in silicon photonics, a technology that uses light instead of copper to move data in data centres. The bank noted optical ports in data centres are growing faster than AI accelerator chips due to rising bandwidth needs. BofA forecasts photonics wafer revenue growth of 172%, 74% and 57% in fiscal 2027, 2028 and 2029 respectively. Several major customers have signed long-term "take-or-pay" contracts, giving Soitec more demand visibility. The bank expects gross margin to rise from 16% in fiscal 2026 to 44% by fiscal 2029 as higher-margin photonics wafers comprise more sales.
