Silan Micro’s cyclical recovery is visible, but high capex and earnings pressure remain the core constraints

Overview

This report is Morgan Stanley's earnings review and risk/reward update on Hangzhou Silan Microelectronics Co. Ltd. (600460.SS). The report acknowledges that the company is benefiting from China's domestic substitution in power semiconductors and the cyclical recovery in power discrete devices, and that its 2026 revenue growth guidance of 19% may be achievable. However, it also emphasizes that the company has been in an aggressive capex cycle since 2022, and that new capacity, depreciation, interest expense, and raw material costs are jointly pressuring margins and cash self-sufficiency.

Core views

The core view is that there is support for a recovery, but capital discipline is insufficient. 1Q26 revenue and gross margin trends are in line with the full-year growth trajectory, and price increases should continue to improve gross margin. However, the company plans to keep investing in 12-inch analog ICs, 8-inch SiC, automotive module packaging, and power discrete device expansion, which is causing leverage to rise materially. The report believes the short-term policy tailwind from domestic semiconductor substitution may continue, but earnings elasticity is limited, and the roughly 10% operating margin in 2026 versus a 39x 2026e EPS valuation does not appear attractive.

Analysis framework

The report adjusts its 2026-2028 earnings forecasts by combining 1Q26 actual operating performance, the company's 2026 sales growth guidance, capex projects, leverage changes, gross margin, and depreciation costs, and uses a residual income model to derive the target price and bull, base, and bear scenarios.

Methodology notes

• Valuation methodsResidual income model

  Base-case target price

  The Rmb20.00 target price comes from the residual income model, which the report believes best reflects the stock's long-term value. Key assumptions include an 8.6% cost of equity, beta of 1.1, a 2.0% risk-free rate, a 6.0% equity risk premium, a 5% payout ratio, an 18% mid-cycle growth rate, and a 5.5% perpetual growth rate.

• Scenario analysisRisk/reward scenarios

  Bull, base, and bear scenarios

  The bull case of Rmb36.10 assumes a 2025-28e revenue CAGR of 25% and gross margin rising to 30% in 2026-28. The base case of Rmb20.00 assumes a revenue CAGR of 15% and gross margin holding at 23%. The bear case of Rmb12.50 assumes a revenue CAGR of 5% and gross margin falling to 15% in 2026.

Asset mapping & comparison

Structured mapping from thesis to named assets (strengths, weaknesses, peers, risks).

• Hangzhou Silan Microelectronics Co. Ltd. (600460.SS)

  Covered company; a beneficiary of domestic substitution in power semiconductors

  Strengths

  Cyclical recovery in power discrete devices, achievable 2026 revenue growth guidance, and IGBT and SiC modules may benefit from adoption by Chinese automotive OEMs and higher domestic share in home appliance IPMs.

  Weaknesses

  Aggressive capex, rising leverage, and depreciation and interest expenses are weighing on earnings. Average net margin in 2023-25 was only about 2%, and 2026e valuation is above the peer average.

  Comparison

  39x 2026e EPS is above the peer average of 35x, which the report sees as expensive.

  Risks

  If demand weakens, capacity expansion slows, technology does not improve, or competition drives prices lower, gross margin and earnings could come in below expectations. If customer adoption, technological breakthroughs, and demand are better than expected, there is upside.

• SiC MOSFETs, IGBT modules, and power discrete devices

  Core products and expansion focus

  Strengths

  SiC MOSFETs began mass shipments in 2025 for AI data center power systems, while also having larger applications in EVs, photovoltaics, and energy storage. IGBT and SiC modules may benefit from adoption by Chinese automakers.

  Weaknesses

  Exposure to AI data center revenue is still small, and server DrMOS and eFuse circuits are still in customer testing, so scaling takes time.

  Comparison

  Compared with the direct AI compute beneficiary chain, the company is currently more exposed to EV, photovoltaic, energy storage, and home appliance power device cycles.

  Risks

  Breakthroughs in SiC and GaN technology and cost declines could create upside; insufficient technical progress or intensifying price competition would be downside.

• Valuation39x 2026e EPSAbove the peer average of 35x.
• Target priceRmb20.00Target price unchanged; the valuation base shifts from 2025 to 2026, offsetting the impact of lower earnings estimates.

Impact & implications

In investment terms, Silan Micro's revenue recovery and domestic substitution logic are not enough to fully offset the earnings pressure from capex, leverage, and depreciation. The report remains attentive to the company's long-term capacity build-out, but before capital discipline improves, gross margin recovery becomes sustainable, and AI-related revenue scales up, it believes the stock offers a weak risk-adjusted return relative to the sector.

Risks

• A continuing capex cycle could push leverage even higher and weaken the company's self-financing ability.
• Depreciation, fixed costs, and interest expense continue to pressure earnings.
• Higher raw material prices could lead to lower gross margin assumptions.
• AI-related revenue exposure is limited, and server-related DrMOS and eFuse are still in customer testing, making the ramp timing uncertain.
• If a macroeconomic downturn weakens demand, sales growth may fall short of expectations.
• Capacity expansion that is slower than expected or a lack of technical improvement could weigh on growth and margins.
• Competition and price declines could cause gross margin to fall to 15% in the bear case.

What to watch

• Quarterly delivery of the 2026 sales growth guidance of 19%.
• Whether gross margin continues to improve after the roughly 10% price increase starting March 1.
• The investment pace in 12-inch analog ICs, 8-inch SiC, Chengdu automotive module packaging, and 12-inch power discrete device expansion.
• Changes in the total debt-to-equity ratio and depreciation expense.
• Progress in Chinese automotive OEM adoption of IGBT and SiC modules.
• Domestic substitution and market share gains in home appliance IPMs.
• Breakthroughs in SiC and GaN technology and cost reduction progress.
• The timeline for server DrMOS and eFuse circuits to move from customer testing to mass production.
