Citigroup maintains Sell on Shanghai Vital Deeptech, raises target price but remains bearish

Overview

This report updates earnings forecasts for Shanghai Vital Deeptech (600641.SS) and introduces 2028 forecasts. Citigroup raised its revenue forecasts and target price, mainly reflecting the company's new bismuth materials business and the re-rating of China's semiconductor equipment sector, but maintains its Sell rating because the significantly higher contribution from the low-margin bismuth materials business has depressed group margins. The company turned loss-making in 2025, and Citigroup expects losses to continue in 2026E-2028E.

Core views

The core view is that the semiconductor equipment business, particularly Kingstone's ion implanters, has a localization-driven investment thesis, but its profit contribution is limited and the US BIS Entity List creates risks for advanced equipment R&D and manufacturing. By contrast, the bismuth materials business has become the main revenue contributor, accounting for 70%-80% of total revenue, but its gross margin is materially below the group's historical level, making earnings recovery difficult. The share price has risen sharply over the past three months along with the WFE sector re-rating. Citigroup believes short-term sentiment may continue to support the share price, but reported losses could trigger a pullback.

Analysis framework

The report evaluates the company using segment revenue and gross margin forecasts, comparisons between Citi and market consensus estimates, a P/B valuation framework, and bull/bear scenario assumptions. The target price is based on 2.9x 2027E P/B, approximately one standard deviation above the five-year average, to reflect the WFE sector re-rating. However, as WFE contributes approximately 30% of the company's profit, the valuation premium is lower than that of other Chinese WFE peers.

Methodology notes

• Valuation methodsPB valuation

  2.9x 2027E P/B

  Citigroup sets a target price of Rmb25.0 based on 2.9x 2027E P/B, approximately one standard deviation above the five-year average of 2.2x, reflecting valuation re-rating from semiconductor equipment and rare-metal themes.

• Scenario analysisBull/bear scenarios

  Revenue growth, gross margin, and valuation multiple assumptions

  The bull-case scenario assumes 2026E/2027E revenue growth of 40%/35% and gross margins of 25%/27%; the base-case scenario assumes revenue growth of 37%/30% and gross margins of 21%/22%; the bear-case scenario assumes revenue growth of 30%/25% and gross margins of 20%/20%.

  Dilution from the bismuth materials business gross margin

  The report focuses on the impact of the bismuth materials business on the revenue mix and group gross margin, concluding that the high proportion of the low-margin business is the core reason for continued losses.

• 600641.SS

  Covered stock

  Strengths

  Benefits from China's semiconductor localization trend; Kingstone is one of the few domestic ion implanter suppliers; the new bismuth materials business expands revenue scale.

  Weaknesses

  The bismuth materials business has low gross margins and a high revenue contribution, weighing on group earnings; the company turned loss-making in 2025 and is expected to remain loss-making in 2026E-2028E.

  Comparison

  Compared with other Chinese WFE companies, Citigroup assigns a smaller valuation premium because WFE contributes approximately 30% of profit, rather than all profit coming from the highly valued semiconductor equipment business.

  Risks

  The share price has already reflected much of the sector re-rating, and disclosure of losses could trigger a pullback; Kingstone faces risks to the supply of key components and technology after being added to the US BIS Entity List.

• Kingstone Semiconductor

  Subsidiary/core asset of the semiconductor equipment business

  Strengths

  Its ion implanter business may benefit from domestic equipment demand from Chinese wafer fabs and memory manufacturers.

  Weaknesses

  Advanced equipment R&D and manufacturing may be restricted by the US BIS Entity List.

  Comparison

  It has scarce localization value, but its contribution to overall company profit is limited.

  Risks

  Key components, technology supply, and advanced-process equipment capabilities are constrained.

Impact & implications

For investors, the target price increase does not represent a more optimistic fundamental outlook, but rather an upward shift in the valuation benchmark following the sector re-rating. Citigroup still sees a mismatch between earnings quality and valuation: if bismuth materials gross margins do not improve materially, revenue growth may not translate into profit. Meanwhile, although Kingstone has localization potential, external restrictions could weaken its advanced equipment capabilities.

Risks

• The bismuth materials business gross margin may improve less than expected, causing group losses to persist.
• The share price has risen sharply with the WFE sector re-rating, and continued losses could lead to valuation retracement.
• Following Kingstone's addition to the US BIS Entity List, its advanced equipment R&D, manufacturing, and key component supply may be affected.
• If semiconductor localization demand or policy support is weaker than expected, valuation support for the equipment business may weaken.

What to watch

• Whether the bismuth materials business gross margin improves materially from 14% in 2025.
• Whether losses in 2026E-2028E narrow progressively as forecast by Citigroup.
• Orders, deliveries, and localization progress for Kingstone's ion implanters.
• The actual impact of the US BIS Entity List on Kingstone's key component and technology supply.
• Whether valuation sentiment in China's WFE sector continues to support the share price or a pullback occurs during the earnings season.
