Ningbo Ronbay Lithium Battery Material (688005) Report Interpretation

Overview

UBS argues that Ningbo Ronbay is positioned to benefit from the transition toward sodium-ion batteries while also recovering in its core high-nickel ternary cathode business. The institution upgrades the stock to Buy, reflecting a higher medium-term earnings outlook and a valuation shift to 25x 2027E P/E.

Core views

UBS upgrades Ronbay from Neutral to Buy and raises its price target by 46%, from Rmb26 to Rmb38, implying 40% upside from the Rmb27.68 price on 17 August 2026. The target is based on 25x 2027E P/E, versus the prior implied 18x and a battery supply-chain average of 17x. UBS considers the premium justified by Ronbay's exposure to new battery chemistries, including sodium-ion batteries, solid-state batteries and LMFP, alongside expected gains in its established NCM cathode business. The central thesis is that sodium-ion battery adoption could create a large new cathode-material market in which Ronbay is already positioned. UBS's cost model indicates that sodium-cell pricing could fall 37% to Rmb0.292/Wh by 2030 and reach cost parity in 2027. It forecasts sodium batteries to account for 6% of total battery shipments in 2030 and 19.3% in 2035. On these assumptions, sodium cathode demand rises from 10kt in 2025 to 1.2mt in 2030, equivalent to roughly 80% of NCM cathode demand; UBS expects polyanion adoption in energy-storage systems to be the main driver. Ronbay's specific sodium opportunity rests on its relationship with CATL and early manufacturing capacity. CATL has committed to procure no less than 60% of its annual sodium-cathode requirements from Ronbay. Ronbay delivered close to 1kt of sodium cathode materials in 1H26 and had completed polyanion NFPP capacity of 18ktpa as of June 2026, while CATL had announced about 40GWh of sodium capacity. UBS forecasts sodium-ion cathodes to contribute 5%, 10% and 20% of Ronbay's cathode shipments in 2026, 2027 and 2028, respectively. The report also argues that the core ternary cathode business has passed its weakest period. UBS expects new middle-nickel high-voltage products, higher Ni9-series shipments, overseas-capacity ramp-up, overseas customers and product-mix improvement to support shipment growth and margin recovery. It forecasts Ronbay's global NCM cathode market share to rise from 10% in 2025 to 12% in 2028E, citing stronger competitiveness in Europe, which it characterizes as the fastest-growing EV region in the year. High-energy-density ternary cathodes are expected to remain preferred for premium EVs and long-range applications. Estimate changes reflect near-term new-business losses but stronger medium-term volumes. UBS cuts its 2026 net-profit estimate by 35% because of losses during the ramp-up of new businesses, while raising 2027-28 net-profit estimates by 6% on higher shipment assumptions and initial SIB earnings contribution. Its revised diluted EPS forecasts are Rmb0.67 for 2026E, Rmb1.52 for 2027E and Rmb1.95 for 2028E, compared with prior forecasts of Rmb1.02, Rmb1.42 and Rmb1.82. UBS forecasts revenue of Rmb27.979bn, Rmb43.420bn and Rmb47.041bn for 2026E-28E, with cathode sales volume increasing from 223,560 tonnes in 2026E to 369,684 tonnes in 2027E and 484,110 tonnes in 2028E. UBS believes the market has not fully priced in the scaling potential of new materials. Ronbay trades at 18x 2027E P/E versus a 17x peer average, while UBS's 2027-28 net-profit estimates are 30-38% above Wind consensus. The report's base-case Rmb38 valuation assumes 6% global SIB penetration and 6% global SSB penetration by 2030, 224kt of 2026E cathode sales volume, 47% sales CAGR in 2026-28E and gross profit per tonne of Rmb8,500. Its scenario range spans Rmb15 downside to Rmb54 upside.

Analysis framework

UBS combines a sodium-battery cost and penetration model with cathode-demand forecasts, Ronbay's customer and capacity position, forecasts for NCM shipment and share gains, earnings revisions, and relative P/E valuation. It compares its earnings estimates with Wind consensus and applies a 25x 2027E P/E multiple to set the target price.

Methodology notes

• Valuation methodsP/E and PEG Valuation

  2027E P/E target-multiple valuation

  UBS values Ronbay using 25x expected 2027 earnings per share, replacing its prior P/BV-ROE approach and comparing the multiple with the 17x battery supply-chain average.

• Industry AnalysisSupply-demand framework

  Sodium-battery cost, penetration and cathode-demand modelling

  The report links projected sodium-cell cost declines and adoption rates to future sodium cathode demand, then assesses Ronbay's capacity and customer position against that demand.

• Industry AnalysisUpstream-Midstream-Downstream Transmission

  Battery-chemistry adoption transmitted to cathode-material demand

  UBS traces expected sodium-ion and energy-storage deployment through to cathode-material volumes and Ronbay's shipment and earnings contribution.

Impact & implications

UBS sees Ronbay as a potential key beneficiary of sodium-ion adoption while retaining exposure to premium and long-range EV demand through high-nickel ternary cathodes. Its valuation case depends on new-materials scaling, sustained NCM share gains and a recovery in profitability.

Risks

• Slower-than-expected solid-state battery adoption could weaken the new-technology valuation case.
• A deteriorating competitive landscape could cause market-share loss and margin erosion.
• Foreign-expansion execution risk could impede the expected overseas growth.

What to watch

• Lithium-price movements, which UBS identifies as a potential catalyst.
• Earnings delivery and the pace of sodium cathode or battery offtake.
• Progress in CATL sodium capacity and Ronbay's sodium-material shipment ramp.
• Evidence of NCM market-share gains and margin recovery from overseas customers and product-mix upgrades.
