Report Interpretation

Overview

This report examines the globalization opportunity for China Grid Tech companies through the power-transformer market, with Sieyuan Electric as the primary company focus. Goldman Sachs argues that structural global grid investment and severe transformer supply constraints create an opportunity for Chinese manufacturers to gain overseas share, particularly benefiting Sieyuan.

Core views

Goldman Sachs identifies globalization as a central theme for its China Grid Tech coverage. It argues that Chinese grid-equipment companies already hold stable domestic positions but have limited exposure outside China, leaving room for overseas share gains as global grid infrastructure is upgraded. Transformers are the focus because their customized, labor-intensive manufacturing process has led to more severe global shortages than in other grid-equipment categories. The report expects the global market for power transformers above 10MVA to grow from US$27bn in 2026E to US$48bn in 2035E. This outlook is described as broadly consistent with expectations from Hitachi Energy and Siemens Energy for global grid investment, on the premise that transformers retain a broadly stable share of overall grid-equipment spending. The demand drivers cited are rising electricity consumption from data centers, income growth and infrastructure construction in emerging markets, replacement of aging infrastructure in developed markets, and global renewable-energy integration. Against this demand backdrop, Goldman Sachs expects Chinese suppliers to continue expanding outside China. Based on China customs data and the institution's estimates, Chinese players' volume share of the ex-China transformer market increased from 5% in 2022 to an estimated 21% in 2026E, supported by strong worldwide demand and suppliers' ability to respond quickly. The report forecasts that share to reach 25% by 2035E. Sieuryn Electric is presented as a key beneficiary of this trend. Goldman Sachs forecasts its ex-China power-transformer market share to increase from 2% in 2026E to 7% by 2035E. Correspondingly, the report projects ex-China transformer revenue to rise from US$0.5bn in 2026E to US$3.2bn in 2035E. The analysis frames this expansion as a meaningful part of the company's valuation opportunity. For valuation, Goldman Sachs assigns Sieyuan's ex-China transformer expansion an implied 4.0x P/S ratio. Its assumptions include applying the same 25x P/E multiple used for the domestic and non-transformer businesses, and discounting projected 2035 ex-China transformer sales of US$3.2bn back to 2026E using a 9.5% cost of equity. The report is Buy rated and sets a 12-month target price of Rmb204.5, based on 25x 2028E P/E discounted back to 2027E at a 9.5% cost of equity.

Analysis framework

The report first assesses structural global transformer demand and the supply constraints specific to customized, labor-intensive transformer production. It then estimates Chinese suppliers' ex-China market-share progression, translates that opportunity into Sieyuan's expected share and revenue growth, and applies P/S and P/E-based valuation assumptions discounted using a 9.5% cost of equity.

Methodology notes

• Industry AnalysisSupply-demand framework

  Global transformer demand and supply-shortage analysis

  The report links grid-investment demand drivers with transformer manufacturing constraints to explain why the market can support continued growth and supplier share gains.

• Industry AnalysisUpstream-Midstream-Downstream Transmission

  Grid-investment drivers flowing through to transformer demand

  Data-center power demand, emerging-market infrastructure, replacement needs and renewable integration are treated as upstream drivers that increase spending on transformers.

• Valuation methodsPS valuation

  Implied P/S valuation for Sieyuan's ex-China transformer business

  Goldman Sachs assigns a 4.0x P/S ratio to the overseas transformer opportunity as part of its valuation assessment.

• Valuation methodsP/E and PEG Valuation

  Forward P/E target-price valuation

  The Rmb204.5 target price is based on a 25x 2028E P/E multiple, discounted back to 2027E using a 9.5% cost of equity.

Impact & implications

Goldman Sachs argues that transformer shortages and structural grid upgrades create a sustained overseas-growth opportunity for Chinese suppliers. In its view, Sieyuan's ability to capture a larger ex-China transformer share is the key mechanism supporting higher overseas revenue and the company's valuation case.

Risks

• Overseas execution could fall short of the report's expectations.
• Margins may be below Goldman Sachs' expectations.
• A slowdown in data-center construction could weaken transformer-demand growth.
