LG Chem Additional Discussion: Deleveraging Path and Warning Lines for Maintaining the BBB Rating

LG Chem Additional Discussion: Deleveraging Path and Warning Lines for Maintaining the BBB Rating

1. Purpose and Treatment

This report is a supplementary note that organises the Q&A from the discussion against the existing reports, focusing on LG Chem’s post-2026 credit deterioration scenarios, short-term debt and interest coverage, LGES profitability excluding subsidies, Petrochemicals’ underlying earnings, and capital allocation after asset disposals.

The discussion points covered here should not be treated as verified new factual findings. They need to be read separately from the context already confirmed in the 2026-05-13 issuer_summary, the analytical hypotheses presented during the discussion, and matters that have not yet been confirmed through primary sources or detailed disclosures.

The central point of the discussion was that LG Chem should not be viewed simply as a petrochemical company, nor as a stable issuer protected only by the equity value of its LGES stake. The credit deterioration thesis converged on the view that Petrochemicals, LGES, Advanced Materials, capex, asset disposals, and short-term debt are not merely separate negative factors; rather, if several adjustment levers fail to work at the same time, they could erode the cushion available to a lower investment-grade issuer.

2. Analytical Read-Through from the Discussion

The conclusion from the discussion is that, when assessing downside pressure over the next 12–24 months, the most important inflection point is whether the deleveraging path actually progresses. Delayed recovery in consolidated earnings should be treated as the preceding cause, while deterioration in liquidity or refinancing conditions should be treated more as the market-visible outcome.

The first visible warning lines are likely to be persistently high short-term debt, lack of recovery in operating cash flow, and interest coverage stagnating near 1x. This does not imply a liquidity crisis. LG Chem has cash, capital-market access, the equity value of its LGES stake, and room for asset disposals. However, if these supports do not translate into debt reduction or lower interest burden, the cushion for a lower investment-grade issuer could be priced by the market relatively quickly.

The business constraints behind this are two-layered. LGES supports LG Chem through equity value and growth potential, but as of 1Q 2026 it remained loss-making at the operating level even including subsidies, and improvement in profitability and free cash flow excluding subsidies has not yet been confirmed. Petrochemicals returned to profit in 1Q 2026, but because this included inventory lag effects and tariff refunds, it is still difficult to conclude that the segment has returned to being a cash-generating source that can support consolidated deleveraging.

Therefore, the strongest warning line would be a combination in which LGES’s losses excluding subsidies do not narrow, Petrochemicals remains weak after excluding temporary factors, and free cash flow, short-term debt, and interest coverage fail to improve even after capex reductions and sales of LGES shares. In that situation, the issue would no longer be a simple wait for business recovery; it would more likely indicate that the deleveraging path needed to maintain the BBB rating has broken down.

3. Organisation of Q&A Content

3.1 Combined Stress and the First Warning Lines

Intent of the question: The first main question sought to identify which constraint would bite first in a post-2026 credit deterioration scenario: a downturn in Petrochemicals, battery-related investment/losses/subsidy dependence including LGES, or rising short-term debt and declining interest coverage. The PM-side hypothesis was that deterioration would be more likely to surface through combined stress — delayed petrochemical recovery, delayed monetisation at LGES, continued capex, and rising short-term debt — rather than through a single industry downturn.

Key points of the answer: The discussion concluded that the factors most likely to affect the market and rating headroom first are rising short-term debt and declining interest coverage. The underlying drivers are delayed monetisation and investment burden in battery-related businesses including LGES. Weak petrochemical market conditions are better understood not as the sole cause, but as an amplifying factor that reduces recovery capacity. Short-term debt is more a symptom than a cause, and it is visible to the market through weaker operating cash flow, a higher net debt-to-equity ratio, and lower interest coverage.

Points explored further in the follow-up: The follow-up question asked how to distinguish whether the increase in short-term debt is a temporary working-capital factor or a structural deterioration in liquidity. The answer was to look not only at the absolute amount of short-term debt, but also at a combination of operating cash flow failing to recover, short-term debt remaining elevated for several quarters, interest coverage remaining near 1x, and refinancing terms for long-term bonds worsening. For 1Q 2026 alone, there remains room to view the deterioration as temporary, including working-capital outflow. However, if there is no reversal from 2Q onward, it should be treated as structural deterioration.

Credit analysis implications: The existing reports confirm the context of company-defined interest coverage of 0.9x in 2025, short-term debt of KRW13.117tn at end-1Q 2026, and negative operating cash flow in 1Q 2026. By contrast, the breakdown of bank borrowings, CP, bond maturities, unused committed lines, and parent-only liquidity has not been confirmed. Therefore, at this stage this should be positioned not as a “liquidity crisis”, but as a “warning stage in which it is necessary to confirm whether the issue is becoming structural”.

3.2 Financial Defence Measures and Capital Allocation

Intent of the question: The second main question sought to confirm which of capex reduction, slower LGES/battery-materials investment, asset disposals, and restraint in shareholder returns would actually serve as adjustment levers to prioritise rating maintenance. The issue behind the question was that, while LG Chem has the equity value of its LGES stake and room for asset disposals, EV batteries and battery materials are strategic businesses, so management’s flexibility to reduce investment may be limited.

Key points of the answer: The discussion ranked the likely feasibility of measures as follows: capex reductions and deferral of investment timing, asset disposals including LGES shares, slower battery-materials and LGES-related investment, and restraint in shareholder returns. Because LGES has indicated a capex reduction policy, this has some practical relevance as a financial defence measure. However, the freedom to fully stop growth areas such as ESS, 46-Series, battery materials, and bioscience is limited. Investment reduction is therefore closer to prioritisation and deferral than outright suspension.

Points explored further in the follow-up: The follow-up question confirmed the conditions under which a sale of LGES shares or other assets would protect bondholders. In the discussion, it was considered necessary for the use of proceeds to be clearly identified as loan repayment, short-term debt reduction, or funding for bond redemptions, and for short-term debt, the net debt-to-equity ratio, and interest coverage to actually improve after the sale. Conversely, if the proceeds are largely allocated to dividends, share buybacks, or growth investment, and short-term debt remains elevated around KRW13tn, asset disposals should be reassessed not as creditor protection but as a competing factor within capital allocation.

Credit analysis implications: The existing reports treat the equity value of LGES and room for asset disposals as supports for credit quality. However, the fact that sale proceeds will not necessarily all be used for debt reduction, the allocation between creditor protection and shareholder returns, future dilution of control, and reinvestment in growth have not been confirmed. From a credit perspective, the focus should not merely be that “there is room for disposals”, but whether debt reduction and a lower interest burden can be confirmed after the sale.

3.3 LGES Profitability Excluding Subsidies and Demand Mix

Intent of the question: The third main question asked whether the main judgement axis for LGES should be not profitability including subsidies, but whether earnings and free cash flow are improving sustainably even after excluding subsidies. The question also sought to confirm which downside factor should be weighted most heavily: North American EV demand, ESS demand, policy support such as IRA, or customer inventory adjustments.

Key points of the answer: The discussion concluded that the key axis should be earnings and free cash flow improvement excluding subsidies, rather than profitability including subsidies. In 1Q 2026, LGES recorded an operating loss even including North American production incentives; excluding subsidies, the loss would be larger. The relative importance of downside factors was organised as follows: North American EV demand and production adjustments by major customers, customer inventory adjustments, uncertainty over policy support such as the IRA, and ESS ramp-up costs. ESS is a support on the demand side, but if ramp-up costs continue, it can also become a constraint on earnings.

Points explored further in the follow-up: The follow-up question asked where the boundary lies between viewing North American EV demand and inventory adjustments by major customers as temporary volume adjustments and judging them to represent a medium-term downward revision to demand assumptions. The answer was to watch for a situation where shipments of North American EV pouch-type batteries decline for several quarters, explanations based on major-customer inventory adjustments turn into downward revisions to production plans, and losses excluding subsidies and free cash flow outflow do not improve even with increased shipments of 46-Series cylindrical batteries and ESS.

Credit analysis implications: The existing reports describe LGES as both a support through equity value and growth potential, and a constraint through consolidated earnings, capex, and subsidy dependence. The current discussion emphasised that the point to confirm is not the 46-Series order backlog or ESS capacity expansion itself, but whether these translate into narrower losses excluding subsidies, reduced free cash flow outflow, and improvement in LG Chem’s consolidated short-term debt and net debt-to-equity ratio. Utilisation rates by customer and plant, contract terms, earnings excluding subsidies, and LGES standalone free cash flow have not been confirmed.

3.4 Petrochemicals’ Troughing and Underlying Earnings

Intent of the question: The fourth main question asked whether the 1Q 2026 improvement in Petrochemicals should be viewed as a troughing sign including temporary factors, or as a structural burden that continues to obstruct the recovery of consolidated credit quality because of capacity additions in China and the Middle East, naphtha prices, and weak product spreads. The issue behind the question was that unless petrochemicals recover in earnest, cash generation on the LG Chem parent side will not return, making it harder to absorb LGES and battery-materials investment.

Key points of the answer: The discussion concluded that the 1Q 2026 improvement in Petrochemicals was closer to troughing including temporary factors than a full-fledged recovery. In 1Q 2026, operating profit improved to KRW165bn and the operating margin to 3.7%, but company explanations indicated that this included inventory lag effects from higher raw-material prices and EU anti-dumping tariff refunds. The 2Q outlook also only indicates that profitability will be maintained through naphtha lag effects and cost reductions, while assuming lower volume from the temporary suspension of NCC No.2. It is therefore still difficult to describe this as a recovery driven by demand, spreads, and utilisation.

Points explored further in the follow-up: The follow-up question asked what conditions would justify judging Petrochemicals not merely as having “bottomed out”, but as having recovered into a cash-generating source that supports consolidated deleveraging. The answer was that operating profit excluding temporary factors needs to continue for several quarters, underlying spreads in NCC, PO, PVC, ABS and other products need to improve, utilisation recovery with profitability needs to be confirmed, and this must be reflected in positive consolidated operating cash flow, improvement in interest coverage above 1x, and clear reduction in short-term debt.

Credit analysis implications: The existing reports position Petrochemicals as LG Chem’s historical core business, while also as a constraint exposed to Chinese capacity additions, Asian oversupply, and declining competitiveness of naphtha-based facilities. The current discussion treated the key dividing line not as whether the segment is in profit or loss, but whether it can generate cash sufficient to support fixed costs, interest payments, and short-term debt reduction. Underlying profit in 1Q 2026 excluding inventory lag, tariff refunds, and cost reductions; product-by-product spreads; utilisation; and segment free cash flow have not been confirmed.

3.5 Deleveraging Path Required to Maintain the BBB Rating

Intent of the question: The fifth main question, in light of S&P affirming the BBB rating while revising the outlook to negative, sought to confirm which inflection point should be seen as raising downgrade risk over 12–24 months: delayed recovery in consolidated earnings, failure to reduce debt, or deterioration in liquidity/refinancing conditions.

Key points of the answer: The discussion concluded that the most important inflection point is failure to reduce debt. Delayed recovery in consolidated earnings is the cause, while deterioration in liquidity/refinancing conditions is the market-visible result. If recovery at LGES and the chemicals business is delayed, and even capex reductions and asset disposals do not lead to lower net debt, reduced short-term debt, and improved interest coverage, that would be most directly connected to S&P’s negative outlook.

Points explored further in the follow-up: The follow-up question asked what combination would indicate not merely a temporary delay while waiting for business recovery, but a breakdown in the deleveraging path required to maintain the BBB rating. The most concerning combination was organised as continued LGES losses excluding subsidies, weak Petrochemicals earnings after excluding temporary factors, and no improvement in free cash flow or short-term debt even after asset disposals and capex reductions. In particular, if short-term debt remains elevated around KRW13tn even after a sale of LGES shares, interest coverage stays near 1x, and operating cash flow does not recover, this would be a fairly strong warning line.

Credit analysis implications: The existing reports describe LG Chem as a lower investment-grade issuer in the BBB/Baa2 area, with business scale, the equity value of LGES, capital-market access, and room for asset disposals, while also facing heavy pressure from interest coverage, net loss, investment cash flow outflow, and rising gross debt. The current discussion distilled this two-sided profile into the question of whether the deleveraging path required to maintain the rating is progressing. S&P’s detailed downgrade thresholds and definitions of adjusted Debt/EBITDA, operating cash flow to debt, free cash flow, and interest coverage have not been confirmed.

4. Relationship with Existing Reports

Category Content Treatment in This Report
Context confirmed in existing reports LG Chem is a lower investment-grade industrial issuer that includes not only the parent-side chemicals, materials, and pharmaceutical businesses, but also LGES to a significant degree on a consolidated basis. Company-defined interest coverage was 0.9x in 2025, and consolidated operating loss, higher short-term debt, and a rising net debt-to-equity ratio were confirmed in 1Q 2026. Adopted as the starting point for credit analysis.
Context confirmed in existing reports Petrochemicals’ return to profit in 1Q 2026 included inventory lag and tariff refunds, while LGES recorded an operating loss in 1Q 2026. Treated in the current discussion as context requiring confirmation of the quality of recovery.
Discussion-based read-through The first warning lines likely to be visible to the market are short-term debt, interest coverage, and operating cash flow, behind which lie LGES/battery-materials investment and delayed petrochemical recovery. Treated as an analytical read-through, not as a new factual finding.
Discussion-based read-through Sales of LGES shares and capex reductions are feasible adjustment levers, but the key question is whether proceeds are used to reduce short-term debt and lower interest burden. Treated as a confirmation axis for capital allocation.
Unconfirmed items Parent-only debt maturities, CP, bank credit lines, unused committed lines, cash reaching the parent from LGES, and detailed allocation of proceeds from LGES share sales remain unconfirmed. To be confirmed through the next disclosures, DART, and rating reports.
Unconfirmed items Quarterly trends in LGES operating profit/loss and free cash flow excluding subsidies, utilisation of North American EV pouch-type battery capacity, margins for 46-Series and ESS, and Petrochemicals’ underlying profit excluding temporary factors remain unconfirmed. Treated as hypotheses in the current discussion, not as factual findings.

5. Ongoing Monitoring Items and Candidates for Transfer to issuer_notes

The following are ongoing monitoring candidates extracted from the current Q&A. None of them represents a credit judgement finalised by this report alone; they should be treated as points to confirm in future research and report updates.

Issue Current Positioning Warning Line or Trigger for Confirmation Materials to Confirm Next Candidate Text for issuer_notes.md
Whether proceeds from LGES share sales are actually used for debt reduction Discussion-based hypothesis. Past disposals have been explained as being used for loan repayment, but future capital allocation is unconfirmed. If short-term debt remains elevated after a sale of LGES shares and interest coverage does not improve from around 1x. LG Chem IR materials, earnings presentation materials, asset-disposal disclosures, DART disclosures, rating-agency comments, and explanations of use of proceeds. LGES share sales are a credit-supportive factor, but it is unconfirmed whether sale proceeds will be clearly used for short-term debt reduction and loan repayment; the priority versus shareholder returns and growth investment needs to be monitored.
LGES losses excluding subsidies and free cash flow outflow Mix of confirmed facts and discussion-based hypothesis. As of 1Q 2026, LGES was loss-making even including subsidies, and losses are larger excluding subsidies. If losses excluding subsidies do not narrow over several quarters and free cash flow outflow continues even after capex reductions. LGES quarterly results, breakdown of IRA and other production incentives, operating profit/loss excluding subsidies, capex, and free cash flow. LGES needs to be monitored not by profit/loss including subsidies, but by improvement in profitability excluding subsidies and improvement in free cash flow after capex reductions.
Whether low utilisation of North American EV pouch-type batteries is temporary inventory adjustment or a medium-term downward revision to demand Unconfirmed item. The company has described it as inventory adjustment, but utilisation by customer and plant and the demand outlook are unconfirmed. If declines in pouch-type EV battery shipments continue for several quarters and LGES’s overall profit/loss excluding subsidies does not improve despite increased shipments of 46-Series and ESS. LGES earnings explanations, EV production plans of major customers, inventory-adjustment comments, plant utilisation, and shipments/margins by product. It remains unconfirmed whether low utilisation of North American EV pouch-type batteries is temporary inventory adjustment or a medium-term downward revision to demand; monitor whether expansion in 46-Series and ESS translates into profitability improvement.
Whether improvement in Petrochemicals returns to being a cash-generating source even after excluding temporary factors Mix of confirmed facts and unconfirmed items. 1Q 2026 improved, but underlying earnings power excluding temporary factors is unconfirmed. If the petrochemical segment is operating-profit positive but this is not reflected in consolidated operating cash flow, interest coverage, or short-term debt reduction. Product-by-product spreads, profitability of NCC/PO, PVC, ABS and other products, utilisation, impact of inventory lag, impact of tariff refunds, and segment cash flow. Petrochemicals’ return to profit should be viewed cautiously as a source of deleveraging until it is reflected in underlying spread improvement excluding temporary factors and improvement in consolidated operating cash flow.
Whether capex reductions actually translate into free cash flow improvement Discussion-based hypothesis. LGES’s capex reduction policy has been confirmed, but the effect on consolidated free cash flow improvement is unconfirmed. If the company continues to fund the shortfall in operating cash flow and investment cash flow with borrowings even after capex reductions. LG Chem and LGES capex plans, quarterly capex, segment investment allocation, free cash flow, and trends in borrowing and repayment. It remains unconfirmed whether the capex reduction policy will translate into free cash flow improvement and short-term debt reduction; the continuing burden of LGES and battery-materials investment needs to be monitored.
Persistently high short-term debt and interest coverage near 1x Mix of confirmed facts and discussion-based hypothesis. In 1Q 2026, the increase in short-term debt and deterioration in operating cash flow were confirmed, but whether this has become structural is unconfirmed. If short-term debt remains elevated, operating cash flow does not recover, and interest coverage remains stuck near or below 1x. Debt maturity schedule, short-term borrowings, CP, breakdown of bond redemptions, unused committed lines, bond-issuance terms, and company definition/trend of interest coverage. If short-term debt remains elevated and interest coverage stays near 1x, LG Chem’s liquidity deterioration should be treated not as a temporary working-capital factor, but as a warning signal of failure to reduce debt.
Conditions under which the financial improvement path needed to maintain BBB is impaired Discussion-based hypothesis. If LGES losses excluding subsidies, weak Petrochemicals earnings after excluding temporary factors, free cash flow outflow after capex reductions, and persistently high short-term debt after LGES share sales appear at the same time. Rating comments from S&P, Moody’s and others; LG Chem results; LGES results; asset-disposal disclosures; debt maturity and refinancing status; and new-issue terms in the bond market. The inflection point for maintaining BBB is not a standalone loss, but a situation in which LGES losses excluding subsidies, weak petrochemical earnings, free cash flow outflow, and persistently high short-term debt after asset disposals overlap, preventing debt reduction.
