Goldman Sachs Maintains Sell on Estun A-Shares and Gives Estun-H Its First Neutral Rating

Overview

This report is Goldman Sachs' company research and earnings review of Estun Automation Co. The firm maintains its Sell rating on Estun-A and initiates coverage on Estun-H with a Neutral rating. The core view is that Estun has a leading share and domestic substitution advantage in the Chinese industrial robot market, and AI software, iER platform, and Codroid humanoid robotics make the long-term valuation framework more durable. However, current A-share valuation already reflects long-term growth fairly well, and gross margin and net margin recovery is still constrained by pricing competition, cost control, and execution history.

Core views

Goldman Sachs believes Estun will continue to benefit from downstream automation demand from automotive, lithium battery, electronics, and metal processing, and is likely to raise domestic industrial robot market share from 10.5% in 2025 to around 15% by 2030E. AI revenue could come through three pathways: AI software packages on industrial robots, the iER open robot platform that supports AI deployment, and Codroid humanoid robots and key component ecosystems. At the same time, the report notes that the company has previously expanded share through price cuts and that gross margin recovery has not shown a stable track record, so despite rising long-term AI optionality, A-shares are still viewed as overvalued while H-shares, trading at a larger discount, are closer to reasonable valuation.

Analysis framework

The report combines 2025 results, 2026E operating guidance, segment revenue, gross margin improvement drivers, industrial robot market share, AI commercialization pathways, A/H-share valuation discount, and peer relative-valuation framework in its analysis. In valuation, A-shares use a 35x 2030E P/E discounted to 2027E at 11.5% cost of equity; H-shares use a 25x 2030E P/E, implying a 30% discount relative to A-shares.

Methodology notes

• Valuation methodsP/E Target Price Method

  Value based on 2030E P/E, discounted to 2027E

  Goldman Sachs shifts valuation from recent earnings to 2030E, arguing that AI and humanoid robotics optionality means the company should not be valued only on near-term earnings. A-shares apply a 35x 2030E P/E and H-shares a 25x 2030E P/E, with both discounted at an 11.5% COE.

• Valuation DiscountH-share Discount Re-rating Analysis

  Determine H-share discount based on factors affecting A/H discount among industrial peers

  The report uses regression analysis of the 12-month average trading discount of industrial peers, finding market cap, H-share dividend yield, and A-share foreign ownership to have stronger explanatory power; therefore it applies a 30% valuation discount for H-shares relative to A-shares.

• Factor AnalysisGS Factor Profile

  Compare stock attributes across growth, financial returns, valuation multiples, and combined factors

  The GS Factor Profile compares the company with covered stocks and industry peers to show growth, financial returns, valuation level, and composite scores. Charts indicate Estun's valuation multiple percentile is relatively high while overall performance is about mid-range.

• M&A PossibilityM&A Rank

  Score from 1 to 3 to assess likelihood of potential takeovers

  The report assigns Estun-H an M&A Rank of 3, indicating a lower probability of being acquired. This is due to high growth potential but concentrated ownership, with the chairman and related parties jointly holding about 42%, likely reducing appetite for a control-related transaction.

Asset mapping & comparison

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

• Estun-A (002747.SZ)

  Company's A-shares; Goldman Sachs maintains Sell rating

  Strengths

  A leading Chinese industrial robot player, with domestic market share of about 10.5% in 2025; demand from automotive, lithium battery, and electronics downstream provides growth momentum; AI and humanoid robots strengthen long-term optionality.

  Weaknesses

  Valuation is relatively high, and target price remains below the current price; historical gross margin management has been uneven; price competition and dilution from H-share issuance affect EPS.

  Comparison

  A-shares are valued at 35x 2030E P/E, higher than H-shares at 25x; there is limited room for A-shares to benefit from a discount re-rating relative to H-shares.

  Risks

  If share gains, margin recovery, or humanoid robot progress exceed expectations, A-shares have upside risk; if competition intensifies or cost optimization falls short of expectations, downside pressure is greater.

• Estun-H (2715.HK)

  Company's H-shares; Goldman Sachs initiates coverage with Neutral rating

  Strengths

  Currently trades at a discount of about 47% relative to A-shares, above the 30% discount the report deems reasonable; target price is about 10% above current price.

  Weaknesses

  Still constrained by groupwide margin recovery, industrial robot competition, and AI commercialization pace; H-share valuation is set with a discount to A-shares.

  Comparison

  H-shares use 25x 2030E P/E, a 30% discount to A-share valuation at 35x 2030E P/E; therefore Goldman Sachs sees H-shares as closer to fair value than A-shares.

  Risks

  H-share performance may be affected if share gains, margin recovery, or humanoid robot progress move significantly faster or slower than expected.

• Industrial robots and system integration

  Company's largest revenue-contributing segment

  Strengths

  2025 revenue was Rmb3,997mn, up 32%; Estun robotics revenue grew more than 50% year-over-year, with domestic shipments around 34k units.

  Weaknesses

  The industry is highly competitive, and ASP declined sharply in the past; some downstream areas such as automotive and automotive electronics face greater pricing pressure.

  Comparison

  The company has become the largest sharesholder in China's domestic industrial robot market, but Fanuc, Kuka, ABB, and Yaskawa remain competitors in the high-end segment.

  Risks

  If high-end market breakthroughs fall short or price wars continue, market share and margins may come in below expectations.

• AI Software, iER Platform, and Codroid

  Source of long-term growth and valuation upside optionality

  Strengths

  AI software can be used in welding, bending, logistics, and depalletizing; the iER platform is more open and suitable for AI integration; Codroid is already collecting data in the company’s own factory.

  Weaknesses

  Humanoid robots are still in prototype iteration and have not yet produced meaningful revenue contribution; commercialization pace remains uncertain.

  Comparison

  The report benchmarks this against long-term growth frameworks of emerging AI robot and humanoid robot peers.

  Risks

  If domestic humanoid robot competition intensifies or the company cannot establish a differentiated commercialization path, AI revenue contribution may be below expectations.

Impact & implications

The key distinction in investment implications is the different valuation positions of A- and H-shares. Although A-shares benefit from China’s industrial robot substitution trend and long-term AI optionality, current valuation already reflects growth fairly well, and the target price remains below the current price. H-shares, with current trading discount around 47%—higher than the 30% reasonable discount used in the report—therefore have relatively stronger valuation support versus A-shares. At an industry level, Estun's AI path is more akin to "physical AI" in industrial settings; if it can use AI to lower programming and deployment costs and shorten customer payback periods, it could expand the range of automation serviceable by robots.

Risks

• Industrial robot market share rising faster or slower than expected.
• Margin trend improving more or less than expected, especially in terms of price competition, raw material costs, SG&A, and R&D expense control.
• Humanoid robot development and commercialization progress being faster or slower than expected.
• A-share valuation remains high, which could pressure share price if profit recovery underperforms.
• H-share discount may be influenced by liquidity, dividend yield, foreign ownership, and market preferences.
• About 11% EPS dilution from H-share issuance.

What to watch

• Whether 2026E revenue approaches the company’s Rmb6bn guidance, and the order contribution from automotive, lithium battery, and electronics.
• Whether industrial robot shipment growth and domestic market share continue to rise from 10.5%.
• Whether gross margin is lifted by 1-1.5 percentage points as guided by the company, or only approaches Goldman Sachs' expected 0.9-point improvement.
• Customer adoption of AI software packages in welding, bending, logistics, and depalletizing scenarios, and changes in payback period.
• Whether the open architecture of the iER platform can attract external developers and support physical AI applications.
• Progress on Codroid in factory data collection, model training, and commercialization.
• Whether cost improvements materialize after shifting European production capacity to China or Poland.
• Whether the A/H share trading discount converges from around 47% toward the 30% reasonable discount assumed by Goldman Sachs.
