Goldman Sachs initiates coverage on CATL: From battery cell leader to energy solutions platform

Overview

This is a Goldman Sachs initiation-of-coverage company research report on CATL. The report argues that CATL is not only the world's largest battery manufacturer but is also leveraging its battery scale, cost advantages, technological leadership, and ecosystem investments to transition toward BESS system integration and energy solutions provision. Goldman Sachs believes this transition is undervalued by the market and could deliver higher margins, stronger market share, more stable earnings quality, and valuation re-rating.

Core views

The report's core views include: first, BESS is not merely an incremental shipment opportunity but CATL's next engine of value creation; second, battery quality remains central to the economics of energy storage projects, and CATL has advantages in cells, cost, lifespan, safety, and warranty credibility; third, CATL's expansion from cells into DC/AC system integration enables it to capture more project value and obtain high-margin, recurring service revenue through LTSA; fourth, power batteries remain the core earnings anchor, with China's EV battery demand expected to grow at a 17% CAGR from 2025 to 2030E and CATL's share potentially recovering to approximately 50%; fifth, SoTP valuation better reflects the differing growth and re-rating rationales of power batteries, BESS, and ecosystem investments.

Analysis framework

The report adopts a sum-of-the-parts (SoTP) valuation framework, separately assessing power batteries and other businesses, the BESS business, and long-term equity investments. A-share valuation primarily references Chinese domestic battery peers and relative growth, while H-share valuation is positioned within a global framework emphasizing ROIC, global leadership, and scarcity value. Operational analysis covers BESS project economics, battery quality, system integration value capture, LTSA service revenue, market share changes, power battery demand growth, and peer gross margin/valuation multiple comparisons.

Methodology notes

• Valuation methodsSoTP sum-of-the-parts valuation

  Power batteries, BESS, and long-term equity investments are valued separately to reflect their different growth curves and re-rating potential.

  For H-shares, the report uses average 2026E-27E EBITDA to value the power battery and other businesses, and 2030E EBITDA to value BESS. It then incorporates a discount factor, net cash, minority interests, and long-term equity investments to derive a 12-month H-share target price of HK$946.

• Business qualityBESS project economics analysis

  Battery degradation, efficiency, safety, and warranty capabilities determine BESS asset IRR, bankability, and customer willingness to adopt.

  The report emphasizes that BESS has shifted from passive energy storage infrastructure to revenue-generating grid assets. Cell quality, BMS/EMS, PCS, and long-term performance guarantees therefore jointly determine project value.

• Competitive advantagesEcosystem and system integration moat

  CATL is building system integration capabilities through PCS partnerships, software partnerships, strategic investments, and testing platform development.

  The report mentions CATL's cooperation with PCS suppliers including Power Electronics, SMA, and Sinexcel, as well as its investment in Zhongheng Electric and construction of the Xiamen Energy Storage Verification Research Institute to strengthen its power electronics, software, and system validation capabilities.

Asset mapping & comparison

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

• CATL A-shares (300750.SZ)

  Core covered asset

  Strengths

  Leadership in power batteries, cost and technological advantages, leading R&D investment, power battery share recovery, and BESS system integration potential.

  Weaknesses

  A-share valuation is more constrained by Chinese domestic battery peers and relative growth.

  Comparison

  The report considers the A-share valuation framework more sensitive to domestic peers and growth than the H-share framework.

  Risks

  EV/ESS demand below expectations, slower-than-expected BESS integration execution, rising BOM costs, intensifying competition, and trade policy uncertainty.

• CATL H-shares (03750.HK)

  Core covered asset

  Strengths

  Global investors place greater emphasis on ROIC, global leadership, and scarcity value, and the report assigns H-shares a higher valuation multiple.

  Weaknesses

  A current H/A premium exists; the report discloses that the current trading premium versus the premium implied by the target requires continued monitoring.

  Comparison

  The H-share target price is HK$946. The report evaluates H-shares within a global framework, emphasizing scarcity value and a leadership premium.

  Risks

  The same as for A-shares, including demand, cost, execution, trade policy, and competitive risks.

• BESS energy storage systems business

  Key driver of valuation re-rating and margin expansion

  Strengths

  Cell quality, system optimization, warranty credibility, DC/AC integration, and LTSA can enhance project economics.

  Weaknesses

  CATL has a shorter track record than established integrators in power electronics, complex EMS, and large-scale turnkey integration.

  Comparison

  The report notes that full-system integrators typically enjoy higher gross margins and EV/EBITDA multiples, and CATL has an opportunity to move toward this business model.

  Risks

  Energy storage demand timing, development of system integration capabilities, actual operating performance, and quality and safety incidents.

Key data

• 12-month H-share target priceHK$946Implies approximately 51% upside; the table discloses a current H-share price of HK$628.
• 12-month A-share target priceRmb566Implies approximately 57% upside.
• China EV battery shipment growth2025-2030E CAGR +17%, reaching 2.64TWhThe report considers power batteries to remain CATL's core earnings anchor.
• CATL China power battery share46% in 2025E to approximately 50% in 2030EThe report believes CATL has begun recovering share in both China and global markets.
• CATL China ESS battery shareOver 20% in 2025E to 40% in 2030EThe report expects China's fragmented ESS battery market to consolidate.
• Share of BESS integrated solutionsApproximately one-third in 2025E to nearly two-thirds in 2030EThe increase in integration is expected to drive BESS gross margin toward 30% and unit gross profit toward Rmb200/kWh.
• LTSA service revenueApproximately 1.5%-2.5% of initial project capex annually, with a 60%-70% gross marginThe report believes LTSA can generate high-margin, predictable recurring revenue.

Impact & implications

If Goldman Sachs' assessment proves correct, CATL's investment thesis will expand from that of a cyclical battery manufacturer to a platform company characterized by system integration, long-term services, and energy solutions. The BESS integration transition could increase project value capture, reduce the impact of hardware price volatility, and support higher valuation multiples. Meanwhile, expanding power battery demand and share recovery provide a foundation for medium-term earnings.

Risks

• EV and ESS demand below expectations.
• Unexpected increases in BOM costs.
• Slower-than-expected execution of the BESS integration transition.
• Trade policy uncertainty.
• Intensifying industry competition.
• Degradation, efficiency, safety, and warranty risks during actual BESS operations.

What to watch

• Whether CATL's China ESS battery share rises as expected to 40% by 2030E.
• Whether the share of BESS integrated solutions in sales increases from approximately one-third to nearly two-thirds.
• Whether the scale, pricing, and gross margins of LTSA contracts align with Goldman Sachs' assumptions.
• Whether power battery share recovery continues, particularly in China's premium NEV and commercial vehicle markets.
• The actual contribution of the Zhongheng Electric investment, PCS partnerships, EMS partnerships, and the Xiamen Energy Storage Verification Research Institute to system integration capabilities.
• Degradation rates, RTE, safety incidents, and warranty claims in BESS projects.
