• Manufacturing revenue (2024): RMB 43.56 billion
• Total group revenue (2024): RMB 76.67 billion
• YoY consolidated revenue change: -8.61%
• Gross profit (2024): RMB 4.91 billion

Vertical integration through large-scale recycling and circular-economy capabilities secures raw material supply and strengthens regulatory alignment. By late 2025 Tianneng achieved an annual lead-acid battery recycling capacity of 1.2 million tonnes and a lithium-ion recycling capacity exceeding 70,000 tonnes per year. In H1 2025, the recycling segment recorded external operating income of ~RMB 1.80 billion, with lead-acid recycling contributing RMB 1.375 billion. These capacities reduce feedstock price exposure, support margins, and position the company to meet China's 2025 waste recycling system standards.

Tianneng's financial position is characterized by strong liquidity and a conservative capital structure. For fiscal 2024 the reported net debt ratio was -22.46%, reflecting cash and bank balances of approximately RMB 21.41 billion against total interest-bearing debt of RMB 18.55 billion, resulting in a net cash position of ~RMB 2.86 billion. The interest coverage ratio of 6.50x indicates comfortable ability to service interest expense, providing bandwidth for capital allocation toward capacity expansion and technology upgrades.

• Cash & bank balances (Dec 31, 2024): RMB 21.41 billion
• Total debt (Dec 31, 2024): RMB 18.55 billion
• Net cash position (2024): ~RMB 2.86 billion
• Net debt ratio (2024): -22.46%
• Interest coverage ratio (2024): 6.50x

Commitment to innovation is evidenced by sustained high R&D and capex spending. R&D investment rose to approximately RMB 2.03 billion in 2024 (from RMB 1.93 billion in 2023), focused on high-safety sodium-ion batteries and lead-carbon ESS. The sodium-ion ESS project was selected for Zhejiang Province's 2025 technology research initiative. Capital expenditure in 2024 totaled RMB 2.50 billion, primarily directed at lithium-ion and intelligent manufacturing upgrades, strengthening Tianneng's transition into new-energy chemistries and advanced production efficiencies.

Tianneng Power International Limited (0819.HK) - SWOT Analysis: Weaknesses

Declining profitability margins across core business segments have materially compressed Tianneng's earnings capacity. The group's overall gross profit margin fell to 6.41% in 2024 from 7.11% in 2023. Net profit margin contracted to 1.69% in 2024 from 2.19% in 2023. For the first half of 2025, net profit attributable to owners recorded a further 27.26% year-on-year decrease. Margin compression is driven by rising raw material costs (notably battery-grade chemicals and metals) and aggressive pricing competition in both lead-acid and lithium-ion segments, particularly affecting OEM electric-vehicle and e-bike contracts.

High dependence on the domestic Chinese market concentrates revenue risk. As of late 2025, nearly all earnings derive from the People's Republic of China despite some overseas growth in UPS and ESS product lines. Total revenue for the latest reported period was RMB 76.67 billion, with overseas sales still a small fraction. Geographic concentration increases exposure to: local regulatory shifts, cyclical softness in the Chinese e-bike market, and macroeconomic fluctuations that could reduce domestic demand.

• Total revenue (latest reported): RMB 76.67 billion
• Overseas revenue share: low single-digit percentage of total (materially smaller than domestic)
• Vietnam localization: planned 2.5 GWh facility - early stage, limited revenue impact to date

Deteriorating liquidity ratios indicate a tightening short-term financial position. The current ratio fell to 1.13 in 2024 from 1.26 in 2023. The quick ratio declined from 0.97 to 0.85 over the same period, and some quarterly data in 2025 reported a quick ratio as low as 0.64. Current liabilities have grown faster than current assets, driven largely by increased bills and accounts payable, which extended to 45 turnover days. This deterioration reduces flexibility to fund working capital or respond to cash-flow shocks.

Operational inefficiencies are increasing as inventory and receivables tie up cash. Inventory turnover days rose by 6 days to 38 days in 2024, signaling inventory buildup and potential mismatches in production planning. Accounts receivable turnover days increased to 8 days, while bills and accounts receivable turnover days reached 19 days (up from 18). Longer credit terms to major customers and slower collections extend the cash conversion cycle and raise carrying costs.

• Inventory turnover days: 2024 = 38 days (up +6 days YoY)
• Accounts receivable turnover days: 2024 = 8 days (increase YoY)
• Bills & AR turnover days: 2024 = 19 days (from 18 days)

There has been a significant decline in net profit attributable to shareholders and basic earnings per share. Profit attributable to shareholders fell 37.29% to RMB 1.14 billion in 2024 from the prior year, producing a basic EPS drop to RMB 1.01 from RMB 1.62 in 2023. For the nine months ended September 30, 2025, net profit continued to decline, recording a 7.13% year-on-year decrease. The sustained erosion of earnings has led to reduced dividend capacity and may weaken investor confidence in the company's growth trajectory amid the lithium transition.

Tianneng Power International Limited (0819.HK) - SWOT Analysis: Opportunities

Accelerating demand for energy storage systems (ESS) driven by global renewable energy transitions presents a substantial revenue opportunity for Tianneng. The global lead-acid battery market is forecast to reach approximately USD 82.27 billion by 2031, with a CAGR of 2.3% starting from 2025. Tianneng is positioning to capture this growth by expanding lead‑carbon and lithium‑ion ESS solutions. The company's 6 GWh lithium‑ion battery base in Zhejiang is operational, with reserve capacity ready for launch; in 2024 the lithium‑ion battery recycling business alone recorded operating income of RMB 573 million. As China advances its 'Dual Carbon' targets, demand for large‑scale grid and industrial storage is expected to create a multi‑billion RMB new revenue stream over the next decade.

Key ESS opportunity metrics and Tianneng capacity:

Strategic expansion into international markets via localized production and sales networks reduces China concentration risk and targets faster‑growing regional markets. Current initiatives include a 2.5 GWh annual production capacity project under construction in Vietnam, and established offices in the Netherlands, Thailand, and Vietnam. In 2023 Tianneng signed cooperation agreements with more than 20 overseas distributors to enhance its global sales network. The Asia‑Pacific lead‑acid market projects 7.1% annual growth; success in these regions could materially improve valuation and lower geopolitical/regulatory exposure.

• Vietnam factory: 2.5 GWh annual capacity (under construction)
• Regional offices: Netherlands, Thailand, Vietnam
• 2023 partnerships: >20 overseas distributors
• Asia‑Pacific lead‑acid growth: ~7.1% p.a.

Tianneng's technological pivot toward sodium‑ion and solid‑state batteries targets the next innovation wave and addresses margin compression in legacy chemistries. The 'High Safety, Low‑Cost Sodium‑ion ESS Battery R&D' project was selected for the 2025 Vanguard technology research initiative. Sodium‑ion offers lower cost and improved safety for large‑scale ESS; solid‑state investments target long‑term power battery competitiveness. Leveraging existing R&D infrastructure and manufacturing know‑how provides potential early‑mover advantages in these emerging chemistries, helping to diversify product mix and improve gross margins over time.

R&D & innovation roadmap highlights:

Favorable regulatory shifts in China are creating near‑term demand tailwinds for lead‑acid products. In early 2025 the Chinese government increased subsidies for replacing lithium‑battery e‑bikes with lead‑acid models based on safety considerations. Tianneng's motive lead‑acid battery business generated RMB 37.18 billion in 2024, and stricter safety standards such as GB38031‑2025 (effective July 2026) will favor manufacturers with established safety records. Continued government support for circular economy initiatives further strengthens the company's recycling and second‑life value chains.

• Motive lead‑acid 2024 revenue: RMB 37.18 billion
• Policy: increased subsidies for lead‑acid e‑bike replacements (early 2025)
• Standard: GB38031‑2025 effective July 2026 (favors proven safety suppliers)
• Recycling support: circular economy incentives aiding RMB 573M recycling income (2024)

Growth in automotive start‑stop and SLI (starting, lighting, ignition) battery segments offers a stable, high‑volume downstream market as global vehicle production stabilizes. Start‑stop batteries represent ~42% of global lead‑acid downstream applications. Tianneng's SLI production adheres to international standards (JIS, DIN), positioning it as a qualifying supplier for global OEMs. The Asia‑Pacific lead‑acid total addressable market is projected at USD 383.29 billion over 2023-2032, and expanding collaborations with electric forklift and stacker manufacturers can capture high‑margin industrial niches.

Priority actions to realize these opportunities include scaling ESS product lines (lead‑carbon, lithium‑ion, sodium‑ion), accelerating international plant commissioning (Vietnam 2.5 GWh), expanding distributor and OEM partnerships, commercializing recycling and second‑life battery services, and accelerating R&D commercialization in sodium‑ion and solid‑state chemistries to capture pricing premiums and margin recovery.

• Scale ESS manufacturing and integrate recycling feedstock to lower COGS
• Complete Vietnam 2.5 GWh plant and localize sales/service
• Expand distributor network in Europe/ASEAN to reduce China exposure
• Commercialize sodium‑ion pilot products and progress solid‑state prototypes
• Pursue OEM contracts for SLI and start‑stop batteries to secure recurring volumes

Tianneng Power International Limited (0819.HK) - SWOT Analysis: Threats

Intense price competition and overcapacity in the global and domestic lithium-ion battery industry have materially compressed margins across the sector. Tianneng reported a contraction in overall gross profit margins in 2024 driven primarily by declining lithium-ion battery margins; major competitors such as CATL invested approximately USD 2.58 billion in R&D in 2024, exerting substantial downward pricing pressure. Excess capacity in China has led to aggressive price competition that disproportionately impacts smaller and mid-tier producers. If Tianneng cannot replicate its lead-acid scale in lithium, it risks margin compression and market share loss in high-growth segments. Maintaining market position requires continuous capital investment in capacity, automation and R&D just to hold share.

Stricter environmental and safety regulations are increasing compliance costs for battery manufacturers. The GB38031-2025 standard (effective July 2026) requires batteries to resist fire/explosion for 2 hours after thermal runaway, necessitating significant upgrades in cell design, production lines and testing protocols. China's MIIT draft rules to curb "unhealthy" capacity expansion in lithium further constrain growth strategies. Tianneng already experienced increased operating expenses due to evolving carbon emission quota compliance in recent fiscal periods. Non-compliance risks include fines, product recalls and restricted market access.

Volatility in raw material prices for lead, lithium and other critical components creates significant cost exposure. Lead price movements directly affect lead-acid cost of sales; in 2024 Tianneng's cost of sales reached RMB 71.76 billion, a large share of revenue, and recycling provides only a partial hedge. The group reported that fluctuations in prices of gold and other traded materials influenced its 2025 interim results. Sustained high commodity prices would further erode already thin net profit margins (reported net profit margin ~1.69%), reducing free cash flow available for investment.

Rapid technological obsolescence is a structural threat as the industry transitions toward alternative energy storage solutions. Emerging technologies - e.g., solid-state batteries and hydrogen fuel cells - could displace traditional lead-acid and liquid-electrolyte lithium chemistries. Tianneng has made investments in new chemistries, but larger competitors and well-funded start-ups may commercialize breakthroughs faster. The global battery start-up index rose by over 100% between January and November 2025, indicating a surge of potentially disruptive entrants. A faster-than-expected shift to new chemistries could strand significant lead-acid assets and require accelerated (and costly) strategic pivoting.

Geopolitical tensions and export controls are constraining the global battery supply chain and complicating international expansion. In July 2025 China introduced new export controls on advanced battery technologies and lithium processing; such measures may limit Tianneng's technology transfer and cross-border partnerships. Potential tariffs and trade barriers in Europe and North America, plus the emergence of regional production clusters, could reduce addressable export markets and increase the cost base for "going out" strategies, adding legal, administrative and localization costs.

The table below summarizes these threats with indicative impacts and estimated cost/financial metrics where available.

Key immediate operational and financial vulnerabilities:

• Margin sensitivity: low net margin (~1.69%) vs. high cost of sales (RMB 71.76bn in 2024).
• Capital intensity: requirement for continuous capex to match lithium competitors (e.g., CATL R&D scale)
• Regulatory compliance cost: GB38031-2025 implementation and carbon/quota obligations.
• Supply risk: exposure to lead, lithium and traded metals price volatility affecting profitability.
• Strategic risk: pace of technology shift (solid-state, hydrogen) and increased start-up competition (index +100% in 2025).
• Market access risk: export controls (July 2025) and potential tariffs in key overseas markets.
