Battery Sector Enters Profit Realization Phase, CATL Remains Core

Overview

This report focuses on the Chinese battery and materials sector's transition from 'price recovery' to 'profit realization'. J.P. Morgan notes the current cycle fundamentally differs from the 2021-22 super-cycle, with market focus shifting to profit durability and cash flow quality. Based on this, the report tactically upgrades CALB and Putailai—whose valuations are attractive and benefit from volume growth—while reaffirming CATL as the industry's 'quality anchor'. For most materials and secondary battery stocks, a range-trading strategy is recommended, with alerts about potential seasonal slowdown in ESS demand in H2 2027.

Core views

This cycle is defined as a 'recovery' rather than a 'super-cycle'. Unlike the 2021-22 period driven by zero interest rates, single-demand explosion, and raw material price surges, the current environment features high interest rates, dual EV+ESS demand drivers, more rational capacity expansion, and moderate ASP gains far below previous peaks. Consequently, stock performance will rely more on sustained EPS recovery than broad valuation multiple expansion, with most targets trading at 15-25x 2027E P/E. Demand shows structural divergence amid upward revisions. Despite downward revisions to Chinese passenger EV sales forecasts, robust ESS growth fully offsets this. Global EV+ESS battery demand forecasts are raised ~20%, reaching 2.6TWh and 3.3TWh for 2026/27. Chinese ESS is the key incremental driver, though H2 2027 shipment slowdown risks loom due to early achievement of the '14th Five-Year Plan' 180GW installation target. Long-term ESS penetration still has massive upside, with short-term volatility not undermining structural growth. Stock recommendations follow a clear stratification strategy. CATL is viewed as the only cyclical-proof core holding, with stable unit net profit at ¥0.10/Wh, 25% ROE, and being the industry's sole consistently positive FCF generator with minimal subsidy reliance (15% of net profit). CALB is upgraded due to high ESS/commercial vehicle exposure, rising B+ vehicle supply share, and significant valuation discount versus leaders. Putailai benefits from successful business transformation from anode to coating separator dominance (>90% net profit contribution), with base film capacity expansion creating new growth vectors and potential valuation re-rating. Conversely, materials like LFP cathodes warrant neutrality due to questionable pricing sustainability despite short-term supply-demand improvement; Guoxuan and Ronbay face Underweight ratings due to stretched valuations or overseas demand uncertainties.

Analysis framework

The report employs cross-cycle comparative analysis, systematically contrasting the 2021-22 super-cycle with the 2025-present recovery cycle across macro rates, demand structure, capacity discipline, price elasticity, and valuation levels to establish a 'profit-over-valuation' investment framework. Bottom-up financial quality screening focuses on unit profit stability, FCF generation, and subsidy reliance, identifying CATL as the 'quality anchor'. Tactical pricing of secondary stocks considers supply chain positioning and marginal changes—e.g., CALB's customer mix optimization and Putailai's business transformation as re-rating catalysts. Policy target backward-mapping analyzes national ESS installation progress to proactively flag potential H2 2027 demand volatility risks.

Methodology notes

• Cycle & Sentiment FrameworkSentiment Inflection Analysis

  Distinguishing driver differences between 'super-cycle' and 'recovery cycle'

  Rather than linearly extrapolating past price logic, the report compares fundamental differences in rates, demand diversification, and capacity discipline across cycles to identify the current phase as profit validation rather than valuation bubble, helping investors avoid flawed historical analogies.

• Company Fundamentals & Financial FrameworkProfit Quality Analysis

  Using unit profit stability, FCF, and subsidy reliance as key filters for core assets

  As the sector shifts from broad gains to divergence, the report identifies cyclical-proof leaders through genuine unit net profit (excluding one-offs/subsidies) and operating cash flow coverage of capex, moving beyond simple growth metrics.

• Industry/Supply Chain FrameworkSupply-demand framework

  Dual EV+ESS demand drivers and policy target impacts on short-term timing

  Beyond total growth, the report dissects EV vs. ESS structural shifts and highlights how policy milestones (e.g., 2027 ESS targets) may cause demand front-loading, alerting investors to nonlinear sentiment distribution over time.

• Valuation MethodologyPE/PEG valuation

  Valuation system reconstruction based on business structure evolution

  For companies like Putailai undergoing business shifts, the report abandons legacy (anode) valuation multiples, instead applying new PE based on growth/margin of dominant businesses (separator), reflecting dynamic valuation adjustments to fundamentals.

Impact & implications

For the industry, this signifies the end of 'price speculation' and start of 'fundamental competition', pressuring tail-end players lacking cost advantages and stable cash flow. For investors, allocation must shift from beta to alpha: core positions should lock in leaders with scale, technology, and pricing power (CATL) for compounding certainty; satellite positions can tactically trade secondary stocks with reasonable valuations and specific catalysts (CALB, Putailai); materials with high homogeneity and capacity elasticity require lowered return expectations and strict buy-low/sell-high discipline. Close monitoring of ESS policy execution is critical to mitigate potential market sentiment shocks from H2 2027 demand vacuum risks.

Risks

• Potential seasonal slowdown in Chinese ESS battery shipments in H2 2027 due to early achievement of policy targets
• Sustained lithium price increases may suppress downstream battery demand
• High sensitivity of materials/secondary battery makers' profits to price and capacity utilization, with large volatility risks
• Global macroeconomic and rate environment changes affecting growth stock valuation centers
• Geopolitical and trade policy shifts impacting Chinese firms' overseas operations

What to watch

• Head battery makers' monthly production growth and ESS shipment sequential changes
• 2027 national ESS installation target progress and subsequent policy continuity signals
• CALB's actual supply share ramp-up at new clients (Xiaomi, Huawei)
• Putailai's Sichuan base film project commissioning progress and customer validation feedback
• LFP cathode processing fee negotiation outcomes and new capacity ramp timing
