SK On Issuer Flash - Q1 2026 Battery Business Results

Report date: 2026-05-21 Event date: 2026-05-13 Event title: Q1 2026 Results

Flash Conclusion

The SK On battery business results confirmed in SK Innovation’s Q1 2026 earnings are positive in the sense that losses narrowed, but they remain insufficient to indicate a clear turn in the business credit profile. The battery business reported revenue of KRW1.79 trillion and an operating loss of KRW349.2 billion, with the operating loss narrowing by KRW91.6 billion versus the previous quarter. The improvement was driven by a modest increase in North American sales volumes and a recovery in European and Asian demand, but profitability excluding subsidies, operating cash flow, and SK On standalone liquidity remain unconfirmed.

The appropriate read-through from this release is limited to: “loss reduction confirmed, but profitability not yet confirmed.” SK Innovation consolidated reported operating profit of KRW2.16 trillion, but this was mainly driven by refining inventory valuation gains and crude oil price lag effects. It does not demonstrate that SK On’s battery business has moved to a position where it can generate cash on a self-sustaining basis. The credit view in the existing issuer_summary is maintained.

Bondholders should distinguish SK On’s business credit from the credit support embedded in KB-guaranteed SKBA bonds. SKBA’s 2027 and 2029 guaranteed senior unsecured green notes benefit from an unconditional and irrevocable guarantee from Kookmin Bank. As long as the guarantee remains effective, the primary payment risk depends on Kookmin Bank and the guarantee agreement.

What Was Announced

On 2026-05-13, SK Innovation announced Q1 2026 consolidated revenue of KRW24.21 trillion and operating profit of KRW2.16 trillion. The main drivers of the consolidated profit increase were higher oil prices, improved refining margins, sales timing lags, and inventory valuation gains. Of SK Energy’s KRW1.28 trillion operating profit, approximately KRW780 billion was attributable to inventory valuation gains.

The key results for SK On’s battery business were as follows.

Metric Q4 2025 Q1 2026 Credit interpretation
Battery business revenue KRW1.46 trillion KRW1.79 trillion Improved due to a modest increase in North American sales volumes and recovering demand in Europe and Asia
Battery business operating loss Negative KRW441.4 billion Negative KRW349.2 billion Improved by KRW91.6 billion QoQ, but the loss amount remains large
Battery business operating loss margin Approximately 30% Approximately 20% Directionally improved. However, profitability, profitability excluding subsidies, and operating cash flow remain unconfirmed
AMPC benefit KRW101.3 billion Not disclosed As there is no Q1 subsidy breakdown, the extent of improvement in underlying earnings power cannot yet be judged
ESS-related Target of 20GWh in global project orders in 2026 Secured 284MW, or 50.3%, in Korean ESS auction This may help reduce dependence on EV demand, but profit and cash conversion remain unconfirmed

For the battery business in Q2 2026, the company cited European local production incentives and subsidies, as well as North American ESS demand related to AI data centres and clean energy, as tailwinds. However, as of Q1, what can be confirmed is limited to a narrowing of losses; operating profitability and cash generation remain unconfirmed.

In the Q1 disclosure, SK On Trading International is presented separately from SK On (Battery Business), with revenue of KRW15.11 trillion and operating profit of KRW15.6 billion. It is necessary to remain aware of the difference in scope between the reorganised SK On legal entity and the battery manufacturing-centred battery business.

Credit Read-Through

The Q1 loss reduction is a small positive for the business credit profile. In Q4 2025, lower sales following the expiry of US EV purchase subsidies, inventory adjustment by North American customers, year-end shutdowns, lower utilisation rates, and a decline in the AMPC benefit coincided, causing the battery business operating loss to widen to KRW441.4 billion. The Q1 improvement indicates, at a minimum, that demand and utilisation were not continuing to deteriorate further.

However, the absolute level remains weak. An operating loss of KRW349.2 billion on Q1 revenue of KRW1.79 trillion means the business is still not sufficiently absorbing fixed costs, pricing pressure, yield issues, warranty costs, subsidy volatility, and customer inventory adjustment. Without confirmation of operating profitability, earnings excluding subsidies, and operating cash flow, it is difficult to describe this as an improvement in repayment resources for creditors.

It is also important not to read consolidated profitability as evidence of SK On improvement. While group earnings certainly create some capacity to support SK On, the credit constraints on SK On’s battery business remain in the standalone profit and loss and cash consumption of the battery business.

ESS is an improvement option, but not yet evidence of credit improvement. The 284MW, or 50.3%, secured in the Korean ESS auction and expected North American ESS demand may help offset slower EV demand. However, as results will depend on pricing, delivery timing, warranties, customer credit, grid connection, and funding, margins and cash conversion should be checked in subsequent periods.

Structurally, SK On’s own credit should be separated from guaranteed securities. SK On operating debt and SK Innovation-guaranteed obligations are affected by the battery business losses, group leverage, and capital policy. By contrast, SKBA’s KB-guaranteed 2027 and 2029 notes depend heavily on Kookmin Bank’s guarantee, so the guarantor, guarantee terms, maturity, and issuer should be identified when assessing the securities.

What To Watch Next

In subsequent periods, Q2 2026 battery business results should be checked to see whether operating losses narrow further, whether profitability excluding subsidies is improving, and whether regional sales volumes and utilisation rates are improving. For ESS, the key issue is how the 284MW Korean auction award and North American demand translate into backlog, deliveries, revenue, gross profit, warranty costs, and working capital.

For the capital structure, the debt layers of SK On / SKBA / SK Innovation should continue to be disaggregated. Items to confirm include SK On standalone cash, borrowings, maturities, collateral, covenants, the post-SK Enmove integration pro forma position, and asset and liability transfers after the BlueOval SK restructuring. For KB-guaranteed SKBA bonds, Kookmin Bank’s bank credit and the effectiveness of the guarantee agreement should be assessed separately.

High Q1 2026 AMPC, European subsidies, and operating profit or loss excluding subsidies Left as an unverified item to judge the quality of the loss reduction
High Sales volumes, utilisation rates, customer inventories, and contract pricing by North America, Europe, and Asia To be checked next time to assess whether the Q1 improvement is sustainable
Medium Revenue conversion, gross profit, warranty terms, customer credit, and delivery timing for ESS / BESS orders There is potential for demand diversification, but evidence is still needed before treating it as credit improvement
Medium Post-SK Enmove integration pro forma, realised EBITDA, and differences between the SK On legal entity and battery segment To be monitored continuously to avoid conflating improvement in the legal entity with improvement in the battery business
Medium Final asset and liability transfers, residual obligations, and additional cash outflows after the BlueOval SK restructuring To be monitored continuously to assess the degree of substantive financial improvement after the 2025 impairment
