Analysis of the Impact of Lithium Iron Phosphate Price Trends on CATL's Gross Profit Margin

I have now collected sufficient data and present the complete analysis report to you.

---

Indicator	Data	Interpretation
Overall Correlation Coefficient	-0.25	Weak negative correlation; raw material prices are not the sole determinant of gross profit margin
Maximum Price Drop	80.6%	From RMB 165,000/ton in early 2023 to RMB 33,000/ton in early 2025
Gross Profit Margin Fluctuation Range	3.2 Percentage Points	From a low of 21.3% in Q3 2024 to a high of 24.5% in Q3 2025
Q3 2025 Net Profit Margin	19.1%	Year-on-year increase of 4.1 percentage points

: The decline in LFP prices has a positive contribution to CATL’s gross profit margin, but the actual performance of gross profit margin is the result of multiple factors, including product structure optimization, scale effects, and changes in industry structure.

Stage	Time Period	Price Change	Core Driving Factors
Rapid Decline Period	2023Q1-Q4	From RMB 165,000/ton to RMB 58,000/ton (-65%)	Collapse in lithium carbonate prices (from RMB 600,000/ton to RMB 100,000/ton) and overcapacity
Bottoming and Volatility Period	2024Q1-Q4	From RMB 58,000/ton to RMB 35,000/ton (-40%)	Deep industry losses and production cuts by enterprises to support prices
Moderate Recovery Period	2025Q2-Q4	From RMB 33,000/ton to RMB 41,200/ton (+25%)	Surge in energy storage demand and rebound in lithium carbonate prices to over RMB 100,000/ton

Time	Lithium Iron Phosphate Price (RMB 10,000/ton)	CATL’s Gross Profit Margin	Remarks
2023Q1	14.7	21.8%	High price level, significant cost pressure
2023Q4	5.8	22.6%	Costs decreased, gross profit margin rebounded
2024Q3	3.7	21.3%	Lowest gross profit margin
2025Q1	3.3	22.4%	Cost dividends released
2025Q3	3.9	24.5%	Gross profit margin hit a new multi-year high

:

Analysis Dimension	Correlation Coefficient	Statistical Significance
Overall Period	-0.25	Weak negative correlation
Price Decline Period (2023-2024)	+0.16	Weak positive correlation (not significant)
Price Recovery Period (2025)	+1.00	Strong positive correlation

:

1. Weak Overall Correlation
   : Gross profit margin is affected by multiple factors, with LFP prices being only one cost-side variable

2. Q3 2024 Paradox
   : Despite low raw material prices, CATL’s gross profit margin hit a new low (21.3%), mainly due to:
   • Intensified industry price wars, continued pressure on downstream battery cell prices
   • Fierce competition due to overcapacity
   • Intensified price pressure from customers and supply chain games

3. 2025 V-shaped Reversal
   : Gross profit margin jumped from 21.3% to 24.5%, driven by:
   • Full release of raw material cost dividends
   • Increased proportion of energy storage business (high-margin products)
   • Improved industry structure and coordinated price stabilization among enterprises

Based on the latest financial report data[3][4]:

Indicator	Q3 2025	Year-on-Year Change	Interpretation
Revenue	RMB 104.186 Billion	+12.9%	Steady growth
Net Profit Attributable to Parent Company	RMB 18.549 Billion	+41.21%	Significantly outpacing revenue growth
Net Profit Margin	19.1%	+4.1pct	Significant improvement in profitability
Gross Profit Margin	25.8%	-5.37pct	Quarterly decline but profit growth

CATL has achieved high-quality growth of “

”, with profit growth (41.21%) significantly outpacing revenue growth (12.9%). The driving factors behind this include:

• Financial expenses in the first three quarters:
  -RMB 7.016 Billion
  (net income)
• Year-on-year increase of 142.41%
• Source: Exchange gains + net interest income

• Affiliated companies contributed 67% of investment income growth
• Positive contributions from overseas business expansion

• Increased capacity utilization
• Emergence of scale effects

Taking early 2023 as the benchmark (LFP price of RMB 165,000/ton):

Time Node	Lithium Iron Phosphate Price	Price Drop	Estimated Cost Savings (as a percentage of total costs)
Early 2024	RMB 48,000/ton	-70.9%	Approx. 13.6%
Early 2025	RMB 33,000/ton	-80.0%	Approx. 15.4%
Late 2025	RMB 41,200/ton	-75.0%	Approx. 14.4%

Note: The calculation assumes that cathode materials account for 35% of costs, and lithium iron phosphate battery shipments account for 55%

Lithium Iron Phosphate Price Change → Gross Profit Margin Sensitivity

Assumptions:
- Cathode material cost proportion: 35%
- Gross profit margin transmission coefficient: 0.3-0.5

Calculation Results:
- If LFP prices increase by RMB 10,000/ton → Gross profit margin decreases by approximately 0.8-1.4 percentage points
- If LFP prices decrease by RMB 10,000/ton → Gross profit margin increases by approximately 0.8-1.4 percentage points

According to forecasts from industry research institutions[5][6]:

Indicator	2025	2026 Forecast
Average Lithium Carbonate Price	Approximately RMB 80,000-100,000/ton	RMB 100,000-150,000/ton
Lithium Iron Phosphate Price	RMB 33,000-41,200/ton	Stabilizes after a slight increase
Battery Pack Price	Year-on-year decrease	Expected to drop another USD 3/kWh

:

• LFP prices increase moderately (+10-15%)
• Costs are passed on to battery products, moderately compressing gross profit margin
• Increased proportion of energy storage business offsets part of the pressure

:

• Tight balance between industry supply and demand continues
• CATL maintains cost leadership through technological and scale advantages
• Gross profit margin is expected to remain in the 23-25% range

Risk Type	Details	Impact Level
Raw Material Price Volatility	Lithium carbonate prices rebound beyond expectations	Medium-High
Industry Price War	Overcapacity triggers a new round of competition	High
Demand Below Expectations	Slowdown in growth of new energy vehicles/energy storage	Medium
Policy Risk	Subsidy withdrawal, trade frictions	Medium

1. Lithium iron phosphate prices and CATL’s gross profit margin show a weak negative correlation; raw material costs are only one of multiple factors affecting gross profit margin

2. The sharp drop in raw material prices from 2024 to 2025 provided significant cost dividends for CATL, but the actual performance of gross profit margin is also comprehensively affected by factors such as product structure, industry competition pattern, and scale effects

3. CATL’s profitability improved significantly in 2025, with a net profit margin of 19.1% (year-on-year +4.1pct), mainly benefiting from the release of cost-side dividends, increased proportion of energy storage business, and reversal of financial expenses

4. Cautiously optimistic outlook for 2026: The tight balance between supply and demand in the lithium battery industry chain is expected to continue, and CATL is expected to maintain good profitability through technological and scale advantages

• Monthly price trends of lithium carbonate/lithium iron phosphate
• Quarterly changes in CATL’s gross profit margin
• Changes in the proportion of energy storage business revenue
• Industry capacity utilization and inventory levels
