Calculate how Tesla-linked sales changes could affect LG Energy Solution revenue using the 19.03% Altsets customer share and explicit offset assumptions.
Dataset reference:Altsets supply chain relationships dataset covers 115k+ entities, 550k+ relationships, and history since 2006 across the full dataset; individual analyses use a narrower scope.
Key findings
- A 20% decline in Tesla-linked sales implies a 3.806% decline in LG Energy Solution total revenue if the rest of the business is unchanged.
- The remaining 80.97% of revenue would need approximately 4.70% growth to offset that decline.
- The 19.03% customer share is company-level exposure and cannot be assigned to one battery chemistry, vehicle program, or storage project.
Tesla is an estimated 19.03% of LG Energy Solution revenue in Altsets' July 30, 2026 snapshot. For an LG Energy Solution investor, the useful consequence is a revenue stress test: how much growth elsewhere would offset weaker sales to this customer?
If Tesla-linked sales fell 20%, with prices, recognition timing and all other sales held fixed, total LG Energy Solution revenue would fall 3.806%. Its other customers would need approximately 4.70% growth to keep the consolidated total unchanged. That is the concentration problem expressed as a business requirement.
What is actually measured
| Relationship | Supplier revenue | Relationship size | Customer COGS |
|---|---|---|---|
| LG Energy Solution to Tesla | 19.03% | 3.2B USD | 3.41% |
These are estimated company-level relationship measures. The 19.03% uses LG Energy Solution revenue as its denominator. The 3.41% uses Tesla's cost base. Comparing the two describes different financial perspectives; their ratio is not an elasticity or a measure of bargaining power.
The offset required from other customers
Normalize starting revenue to 100: Tesla contributes 19.03 and the rest contributes 80.97. The required other-customer growth is the lost Tesla-linked revenue divided by that 80.97 base.
| Assumed decline in Tesla-linked sales | Effect on total revenue if other sales are flat | Other-customer growth needed to offset it |
|---|---|---|
| 10% | −1.903% | 2.35% |
| 20% | −3.806% | 4.70% |
| 30% | −5.709% | 7.05% |
These are conditional calculations, not a forecast of Tesla orders. They deliberately leave replacement capacity, pricing and margins unresolved. Replacing the revenue can also leave profit below the original plan if the replacement business earns less or needs extra investment.
My view is that a thesis relying on diversification should name where the offset comes from. “Other battery demand” is too vague when one customer occupies almost a fifth of the mapped revenue base. The company needs buyers, qualified products and capacity that can actually absorb the displaced business.
Tesla vehicle demand is an imperfect customer-sales proxy
LG Energy Solution's passenger EV and cylindrical battery materials supply product context. They do not allocate this company-level relationship to a specific vehicle, cell format, chemistry or factory.
A Tesla vehicle-delivery change therefore should not be entered directly as an equal change in LG Energy Solution's Tesla sales. Inventory, supplier allocation, price and the scope of purchased products can break that equality. The model needs a separate assumption for purchases from this supplier.
This page answers the downside offset question. Whether an expanding customer relationship deserves a higher valuation is addressed in customer concentration and forecast visibility, which examines how to distinguish new customer wins from weakness elsewhere.
