Soitec (SOIT): J.P. Morgan upgrades Soitec to Overweight as Silicon Photonics overwhelms legacy-business concerns

Overview

J.P. Morgan upgrades Soitec to Overweight after materially raising its outlook for Silicon Photonics. The central argument is that faster optical-networking demand, better volume visibility and unusually high contribution margins can transform the company's revenue mix and earnings power, outweighing continuing weakness and share-loss risk in its legacy businesses.

Core views

The rating change is driven by a major reassessment of Silicon Photonics rather than an improvement in Soitec's legacy operations. J.P. Morgan still expects a weak near- and medium-term Mobile market, continued channel-inventory digestion and longer-term RF-SOI share erosion. It is also more cautious than consensus about the Automotive & Industrial recovery. Nevertheless, the report now expects Silicon Photonics revenue to exceed €1 billion in FY30, with a contribution margin above anything the group has historically delivered. This changes the relative importance of the businesses: an approximately €80 million FY29 Mobile revenue shortfall becomes immaterial beside the projected upside from Silicon Photonics. The demand upgrade mainly reflects higher expected transceiver volumes, with little change to the report's CPO and NPO assumptions. Customer capacity reservation agreements provide greater certainty over committed volumes and usually run for two to three years. Because these agreements generally reserve volume rather than fix price, J.P. Morgan believes Soitec retains near- to medium-term pricing upside while the market remains tight. Most current demand relates to Scale Out, while demand is beginning to emerge for Scale Up and Near-Packaged Optics. Although transceiver-volume growth is assumed to slow as CPO and NPO gain share, wafer demand can continue growing because these architectures require greater silicon-photonics content. Customers are qualifying supply from both the 300mm Singapore facility and France. Supply expansion broadly aligns with this demand trajectory, but it requires substantial investment. J.P. Morgan estimates that Soitec's current footprint has capacity headroom for approximately 0.5-0.7 million additional SOI wafers through conversion of Bernin 4 from Smart SiC and tooling of Singapore Phase 1. Extending Singapore could add approximately 1.0 million 300mm SOI wafers, cost about €700 million and take roughly two years. Because the forecast includes approximately 0.85 million more Silicon Photonics wafers shipped in FY30 than in FY27, the base case assumes the Singapore extension is initiated. An upside scenario would reallocate existing capacity from less profitable products to Silicon Photonics and avoid further expansion, but this is not the report's base case. The model also retains medium-term market-share erosion, most likely to Global Wafers as its dedicated Missouri SOI plant completes qualification. The anticipated ramp is rapid. J.P. Morgan estimates a Silicon Photonics exit rate in FY27 of about $125 million per quarter, equivalent to $500 million annually or approximately €450 million. Its Edge & Cloud AI revenue forecasts rise to €394 million in FY27, €696 million in FY28 and €1.042 billion in FY29. Relative to its previous estimates, those figures are 11%, 59% and 77% higher. This lifts total group revenue forecasts to €704 million, €1.057 billion and €1.475 billion in FY27-FY29, respectively, representing upgrades of 6%, 32% and 44%. Compared with Bloomberg consensus, group revenue is still 3% lower in FY27 but 15% higher in FY28 and 25% higher in FY29. The legacy-business outlook remains deliberately conservative. Mobile revenue is forecast at €238 million, €282 million and €342 million in FY27-FY29, respectively, which is 18%, 21% and 19% below Bloomberg consensus. J.P. Morgan does not expect Mobile to return to more than €400 million of annual revenue during the forecast period, citing negative handset volumes, inventory digestion, competition and likely share loss to Global Wafers. Automotive & Industrial revenue is forecast at €72 million, €80 million and €91 million, reflecting a view that improving end markets will take time to reach Soitec because IDM and channel inventories remain high and competition may pressure both price and volume. Combined Mobile and Automotive & Industrial forecasts are €50 million, €78 million and €90 million below consensus in FY27-FY29, but the report argues that these segments will become immaterial earnings drivers as Silicon Photonics expands. The mix shift creates powerful operating leverage. Investors have tended to anchor expectations to the FY23 RF-SOI-cycle peak gross margin of 37.0%, but J.P. Morgan expects Soitec to exceed that level in FY28 and expand further thereafter. Historical group contribution margins were approximately 60-65%, whereas Silicon Photonics is estimated to earn more than 75%. Flexible pricing and tight supply should help sustain this advantage in the near to medium term, and the changing mix is expected to lift group contribution margin above 70% during the forecast period. Even after allowing for higher manufacturing costs, depreciation, capital expenditure and operating expenses, gross margin is forecast at 27.3% in FY27, 41.0% in FY28 and 46.4% in FY29, while adjusted operating margin rises from 9.3% to 28.6% and 36.9%. The report therefore expects gross margins above 40%, movement into the mid-40s in FY29-FY30 and operating margins above 30%. These assumptions produce large earnings revisions. Adjusted operating income forecasts rise to €65 million, €303 million and €545 million for FY27-FY29, increases of 613%, 278% and 190% from the previous model. Diluted EPS rises to €1.21, €6.63 and €12.25, compared with previous estimates of a €0.28 loss, €1.42 and €3.89. Against Bloomberg consensus, FY28 and FY29 diluted EPS are 125% higher in both years. Free cash flow is forecast at €253 million in FY27, €97 million in FY28 and €67 million in FY29; the FY28 moderation reflects the expected capital-investment step-up. Management's cost discipline under CFO Jacquemont and CEO Remont supports the margin outlook, while a new research-grant program could create upside because the model does not assume the FY27 grant-income shortfall reverses in FY28. J.P. Morgan sets a Jun-28 price target of €200, up from €98, by applying a 13.0x FY29E EV/EBIT multiple. The report switches from EBITDA to EBIT because EBIT better captures the business's capital intensity and the value accruing to shareholders; it also aligns with management's increasing focus on operating profit. The selected multiple is aligned with wafer-manufacturer peers and is equivalent to about 10x EBITDA, versus the prior 11.0x EBITDA multiple. The report concludes that forthcoming consensus upgrades should force investors to reassess Soitec and that improved demand duration and internal visibility measures could allow the shares to be viewed as a longer-duration investment rather than merely a cyclical trading vehicle.

Analysis framework

J.P. Morgan first separates Silicon Photonics from Soitec's legacy Mobile and Automotive & Industrial operations. It then models demand by application, incorporates customer reservation agreements and pricing flexibility, compares expected wafer shipments with existing and potential capacity, and allows for future market-share and price erosion. The report translates the resulting volume and product-mix changes into contribution, gross and operating margins, compares the forecasts with prior estimates and Bloomberg consensus, and values the company using a peer-aligned FY29 EV/EBIT multiple.

Methodology notes

• Industry AnalysisSupply-demand framework

  Silicon Photonics demand and capacity matching

  The report compares demand from transceivers, Scale Out, Scale Up, CPO and NPO with current manufacturing headroom and a potential Singapore expansion to determine whether Soitec can meet projected wafer requirements.

• Industry AnalysisVolume-price decomposition

  Volume commitments with floating prices

  Capacity reservation agreements improve visibility into volumes without generally fixing price, allowing the report to model committed demand separately from potential pricing gains in a tight market.

• Corporate Fundamentals and FinanceOperating and Financial Leverage Analysis

  Contribution-margin and fixed-cost operating leverage

  The report estimates how Silicon Photonics contribution margins above 75%, combined with high fixed costs, can convert revenue and mix growth into disproportionately larger gross profit, EBIT and EPS.

• Valuation methods

  FY29 EV/EBIT peer-multiple valuation

  The €200 price target applies a 13.0x FY29E EV/EBIT multiple aligned with wafer-manufacturer peers. J.P. Morgan prefers EBIT to EBITDA because it more fully recognizes the company's capital intensity.

Impact & implications

The report argues that Soitec's earnings profile is shifting from dependence on Mobile and other cyclical legacy markets toward a faster-growing, higher-margin Silicon Photonics franchise. If the demand, pricing and capacity assumptions hold, consensus revenue, margin and EPS estimates would require substantial upward revisions, supporting the upgrade and higher price target despite continued share-loss, capital-intensity and execution concerns.

Risks

• Heightened Silicon Photonics competition could pressure Soitec's volumes and pricing.
• Constraints on Soitec's ability to expand Silicon Photonics supply could prevent it from meeting demand.
• A slower data-center buildout or weaker growth in Scale Across, Scale Out and Scale Up applications could reduce demand.
• Working-capital improvement initiatives could damage revenue, market share or profitability.

What to watch

• Whether customer reservation agreements continue to improve volume visibility while preserving pricing flexibility.
• The timing and execution of the proposed Singapore capacity extension, including its approximately €700 million capital requirement.
• The pace of customer qualification and demand ramp at the Singapore 300mm facility and in France.
• Silicon Photonics progress toward the approximately $125 million quarterly FY27 exit rate and more than €1 billion of FY30 revenue.
• Mobile inventory digestion, handset volumes and market-share losses, particularly against Global Wafers.
• Whether gross and operating margins exceed their prior peaks as the product mix shifts toward Silicon Photonics.
