Idemitsu Kosan (5019) FY2026 Q3 Earnings Report

Quick View

Executive Summary

For the cumulative Q3 period of the fiscal year ending March 2026, the Company posted a substantial decline in both revenue and earnings, primarily due to deteriorating profitability in the Fuel Oil and Resources businesses. Revenue was ¥5 trillion 9,445.9B (-13.6% YoY), Operating Income was ¥366.9B (-70.2%), Ordinary Income was ¥549.9B (-66.8%), and Net Income attributable to owners of the parent was ¥525.8B (-58.7%). The Operating Income margin contracted by approximately 1.2pt YoY to 0.6%; the substantial decline in Operating Income, exceeding the rate of revenue decline, indicates negative operating leverage.

Factors Affecting Performance

【Revenue】Revenue decreased 13.6% YoY to ¥5 trillion 9,445.9B. By segment, Fuel Oil accounted for the largest share at ¥4,992.1B (83.9% of total, down 13.5% YoY), followed by Resources at ¥1,499.7B (down 25.1%), Advanced Materials at ¥3,906.4B (down 2.1%), Basic Chemicals at ¥3,622.3B (down 22.7%), and Power & Renewable Energy at ¥744.9B (down 24.7%). The structure of the business is such that crude oil prices, refined product market conditions, and inventory valuation in the Fuel Oil segment have a substantial impact on consolidated revenue.

【Profit and Loss】Operating Income decreased 70.2% YoY to ¥366.9B. Operating Income in the Fuel Oil segment declined 82.1%, from ¥713.2B to ¥127.8B, while its margin contracted from approximately 1.23% to 0.26%. Resources also declined 57.0%, from ¥527.0B to ¥226.5B. In contrast, Advanced Materials recorded higher earnings of ¥290.0B (+29.7% YoY), with its margin improving to 7.4%; it was the largest contributor to Operating Income during the period. Basic Chemicals posted an Operating Loss of ¥121.2B, with the loss widening. Ordinary Income was ¥549.9B, supported by non-operating income of ¥183.0B, including interest income of ¥141.4B and foreign exchange gains of ¥83.2B. Net special gains and losses resulted in a gain of ¥92.7B, including a ¥78.8B gain on negative goodwill arising from the additional acquisition of interests in the Bogabrai coal mine in Australia. In conclusion, the Company recorded declines in both revenue and earnings.

Segment Analysis

Fuel Oil recorded Revenue of ¥4,992.1B (83.9% of total, down 13.5% YoY) and Operating Income of ¥127.8B (down 82.1%), representing a substantial decline and having the largest impact on consolidated earnings. Resources recorded Revenue of ¥1,499.7B (down 25.1%) and Operating Income of ¥226.5B (down 57.0%), with its margin declining significantly from 26.3% to 15.1%. Advanced Materials recorded Revenue of ¥3,906.4B (down 2.1%) but higher Operating Income of ¥290.0B (+29.7%), with its 7.4% margin at the highest level among all segments. Basic Chemicals posted an Operating Loss of ¥121.2B, widening from the ¥52.1B loss recorded in the previous year, while Power & Renewable Energy improved, posting an Operating Loss of ¥8.8B compared with a ¥64.4B loss in the previous year. The earnings growth in Advanced Materials was insufficient to offset the scale of declines in Fuel Oil and Resources. Across the portfolio, continued reliance on the highly market-sensitive Fuel Oil and Resources businesses remains the primary driver of earnings volatility.

Key Financial Indicators

【Profitability】The Operating Income margin contracted to 0.6% from approximately 1.8% in the same period of the previous year, while the gross profit margin remained at 7.3%. ROE was 2.7%, with the low Operating Income margin constraining capital efficiency. 【Cash Flow Quality】Non-operating income of ¥353.4B was equivalent to 96.3% of Operating Income of ¥366.9B, indicating a high degree of reliance on interest income and foreign exchange gains. Comprehensive Income of ¥878.8B substantially exceeded Net Income of ¥486.7B, with foreign currency translation adjustments of ¥369.5B serving as an increasing factor. 【Investment Efficiency】Special gains of ¥210.2B included a ¥78.8B gain on negative goodwill, indicating that non-recurring factors contributed to earnings to a certain extent during the period. 【Financial Soundness】The Equity Ratio declined to 34.1% from 36.0% in the previous year. While total assets expanded to ¥5 trillion 2,579.7B, cash and deposits remained at ¥2,399.0B, resulting in a financial structure with relatively high reliance on short-term funding.

Cash Flow Analysis

Although disclosure of the cash flow statement is limited, changes in the balance sheet provide some insight into funding trends. Cash and deposits increased by ¥741.4B from ¥1,657.6B in the previous year to ¥2,399.0B, while reliance on short-term funding increased, with short-term borrowings of ¥6,921.2B and commercial paper of ¥3,056.7B. Inventories increased from the previous year to ¥1 trillion 3,111.0B, representing 24.9% of total assets; the expansion of working capital may affect liquidity management. Property, plant and equipment also expanded from ¥1 trillion 509.9B, indicating continued investment activity. At the same time, the Company is experiencing both a contraction in Operating Income and increased reliance on borrowings.

Earnings Quality

Regarding the quality of earnings for the period, attention should be paid to the relatively high reliance on non-recurring factors. Special gains of ¥210.2B included a ¥78.8B gain on negative goodwill arising from the additional acquisition of interests in the Bogabrai coal mine in Australia, equivalent to approximately 16.2% of Net Income of ¥486.7B. Non-operating income of ¥353.4B was primarily composed of foreign exchange gains of ¥83.2B and interest income of ¥141.4B, and supported Ordinary Income at a level comparable to Operating Income of ¥366.9B. While the core business’s Operating Income declined substantially by 70.2% YoY, the rates of decline in Ordinary Income and Net Income (-66.8% and -61.4%, respectively) were lower, as non-operating and special gains and losses provided supplementary support. In terms of earnings quality, the sustainability of a recovery in core business earnings warrants close monitoring.

Earnings Forecast and Guidance

Cumulative Q3 progress against the full-year Company plan was approximately on track for Revenue, at 74.8% against the forecast of ¥7 trillion 9,500B, while Operating Income reached only 54.0% against the forecast of ¥680.0B, substantially below the customary benchmark of 75%. Ordinary Income progress was 64.7% against the forecast of ¥850.0B, and Net Income progress was 70.1% against the forecast of ¥750.0B. Support from non-operating and special gains and losses has partially mitigated the shortfall against plan. Achieving the full-year Operating Income plan will require approximately ¥313B of Operating Income in Q4 alone, making a recovery in profitability in the Fuel Oil and Resources segments the key to meeting the plan.

Shareholder Returns

The Q2 dividend was ¥18.00 per share, and the full-year dividend forecast is ¥36.00, assuming an equivalent amount for the year-end dividend. Based on the number of shares outstanding, the annual total dividend is estimated at approximately ¥464B, resulting in an estimated Payout Ratio of approximately 61.9% against the full-year Net Income forecast of ¥750.0B. This level is slightly above the guideline for sustainability based solely on dividends, and maintaining the full-year dividend is relatively dependent on achieving the earnings plan for Q4. No data on share buyback execution has been disclosed; therefore, the assessment here is based on the Payout Ratio.

Risk Factors

1. Market dependence risk: The Fuel Oil segment recorded a 13.5% YoY decline in Revenue and an 82.1% decline in Operating Income. Fluctuations in crude oil prices, product spreads, and inventory valuation directly affect consolidated earnings.

2. Deteriorating profitability in the Resources business: Operating Income in the Resources segment declined 57.0% YoY, and its margin fell from 26.3% to 15.1%. The segment is highly sensitive to fluctuations in coal prices and operating and transportation costs in Australia.

3. Reliance on short-term funding and interest burden: The Company relies on short-term funding, including short-term borrowings of ¥6,921.2B and commercial paper of ¥3,056.7B. Compared with cash and deposits of ¥2,399.0B, liquidity requires some attention. Pre-tax income of ¥642.6B provides approximately 4.9x coverage of interest expenses of ¥130.8B.

Key Takeaways from the Financial Results

1. The Operating Income margin contracted to 0.6%, with deteriorating profitability in the Fuel Oil and Resources segments serving as the primary driver of volatility in consolidated earnings. Advanced Materials recorded higher Operating Income of ¥290.0B (+29.7% YoY), with a 7.4% margin at the highest level among all segments, highlighting its relative strength within the portfolio.

2. Progress against the full-year Operating Income plan was 54.0%, below the customary benchmark. Whether profitability in Fuel Oil and Resources recovers in Q4 will be the decisive factor in achieving the full-year plan.

3. Ordinary Income and Net Income were supported to a certain extent by non-operating income, including foreign exchange gains of ¥83.2B and interest income of ¥141.4B, as well as special gains of ¥210.2B, including a ¥78.8B gain on negative goodwill. The gap between core operating earnings and bottom-line earnings is an important point for understanding the earnings structure.

Theoretical Share Price (Reference Value)

Sensitivity: ¥1,206–¥1,275 at ±1% for the Cost of Equity, and ¥1,232–¥1,244 at ±0.1 for ω.

Notes:

• Because forecast ROE is below the Cost of Equity, the theoretical value is below Book Value per Share.
• Net assets as of the quarter-end are used; there is a timing difference from the full-year forecast.
• Because net assets include non-controlling interests, the theoretical value may be calculated somewhat higher.

AI Financial Analysis

Executive Summary

Idemitsu Kosan’s FY2026 Q3 cumulative earnings were materially weaker year on year, as lower petroleum-related sales and a sharp contraction in Fuel Oil profitability more than offset resilience in High Functional Materials and Resources. Revenue declined 13.6% year on year to ¥5,944.6bn. Operating income fell 70.2% to ¥36.7bn, while profit attributable to owners of parent declined 58.7% to ¥52.6bn. The operating margin compressed by 117bp year on year to 0.6%, from 1.8%. Gross margin narrowed modestly by 11bp to 7.3%, but the SG&A-to-sales ratio increased by approximately 106bp to 6.6%, creating substantial negative operating leverage. Fuel Oil segment operating income fell 82.1% to ¥12.8bn despite remaining the largest revenue segment, reflecting the sensitivity of the group’s earnings to market conditions in its core downstream business. Basic Chemicals remained loss-making, with its operating loss widening to ¥12.1bn from ¥5.2bn. High Functional Materials was the principal operating-profit contributor at ¥29.0bn, up 29.7%, and its segment margin improved to 7.4%. Resources operating income fell 57.0% to ¥22.6bn, though the segment received a ¥7.9bn negative-goodwill gain below operating income following an additional acquisition in the Australian Boggabri coal mine. Non-operating income of ¥35.3bn was unusually significant relative to operating income, including ¥14.1bn of interest income and ¥8.3bn of foreign-exchange gains. Pre-tax income exceeded ordinary income because extraordinary gains of ¥21.0bn outweighed extraordinary losses of ¥11.8bn, supporting reported net income. This includes acquisition-related negative goodwill and a gain on step acquisitions, reducing the recurrence quality of bottom-line earnings. Annualized ROE was only 3.9%, with low profitability rather than insufficient asset turnover as the principal limitation. Liquidity remains positive on a current-ratio basis at 120.2%, but the quick ratio of 66.3% shows material reliance on inventory monetization. The capital structure has become more short-term funding dependent, with short-term loans increasing 44.3% year on year to ¥692.1bn and short-term debt representing 58.9% of interest-bearing debt. Management’s full-year forecast implies a substantial Q4 earnings recovery, especially in operating income, making refined-product margins, chemical spreads, foreign exchange and inventory discipline central monitoring variables.

Profitability Analysis

The reported annualized DuPont ROE of 3.9% comprises a 0.9% net profit margin, 1.507x asset turnover and 2.93x financial leverage. The main constraint is the very low net margin, not asset utilization: revenue turnover is relatively robust for a high-volume energy distributor, while financial leverage provides a meaningful uplift to equity returns. The operating margin deteriorated to 0.6% from approximately 1.8% in FY2025 Q3, a 117bp contraction and the largest adverse movement in the earnings structure. Gross margin declined only modestly to 7.3%, but SG&A rose 2.8% to ¥394.7bn while revenue fell 13.6%, increasing the SG&A ratio to 6.6% and demonstrating unfavorable operating leverage. The Fuel Oil segment, the core business by revenue at ¥4,982.7bn, saw operating income contract to ¥12.8bn from ¥71.3bn; its operating margin fell to 0.3% from 1.2%. Basic Chemicals’ operating loss widened to ¥12.1bn, equivalent to a negative 3.3% margin, from a ¥5.2bn loss. In contrast, High Functional Materials produced ¥29.0bn of operating income on ¥390.6bn of sales, a 7.4% margin versus 5.7% a year earlier, demonstrating materially higher earnings quality and margin resilience than the commodity-linked segments. Resources generated a 15.1% operating margin, but operating income declined to ¥22.6bn from ¥52.7bn as segment revenue fell 25.1%. The reported five-factor DuPont interest burden of 1.751x exceeds 1.0x because non-operating income exceeded net interest expense, rather than because the debt load is immaterial. Interest expense increased 11.2% to ¥13.1bn, while interest coverage weakened to 2.81x, below the 3x caution threshold. The 24.3% effective tax rate and 0.818 tax burden are normal; the shortfall in returns is operational. Annualized ROIC of 1.4% confirms that capital is currently earning a modest return relative to the scale of the asset base and funding employed.

Growth Assessment

Revenue weakness was broad-based: Fuel Oil sales declined 13.6%, Basic Chemicals fell 22.3%, Power and Renewable Energy declined 24.5%, and Resources decreased 25.1%. High Functional Materials was the exception, with external sales declining only 2.1% and operating income increasing 29.7%, indicating improved product mix, pricing, cost control or all three. The FY2026 full-year forecast calls for revenue of ¥7,950.0bn, down 13.5% year on year, broadly consistent with the 74.8% Q3 progress rate versus the standard 75% seasonal benchmark. Q3 operating-income progress is only 54.0% against the ¥68.0bn full-year forecast, 21 percentage points below the standard 75% benchmark. Ordinary-income progress is 64.7% against the ¥85.0bn target, and profit attributable to owners progress is 70.1% against the ¥75.0bn target. Accordingly, the full-year plan requires Q4 operating income of ¥31.3bn, nearly 85% of the cumulative nine-month operating income, versus Q3 cumulative operating income of ¥36.7bn. The forecast therefore embeds a sharp final-quarter recovery in underlying trading conditions and/or inventory-related margins. The High Functional Materials business is the strongest internal offset to cyclical downstream and chemicals volatility, but its current sales base remains small relative to Fuel Oil. Resources remains strategically relevant given its high segment margin, although earnings are exposed to coal prices, production performance and Australian asset conditions. Earnings quality is weakened by a high contribution from non-operating and extraordinary items, so sustainable growth depends primarily on recovery in Fuel Oil and Basic Chemicals operating profitability rather than reported net-income momentum.

Financial Health

The current ratio is 120.2%, above 1.0x, and working capital is ¥492.0bn, indicating that reported current assets exceed current liabilities. However, the quick ratio is only 66.3%, meaning that liquidity is materially dependent on inventories of ¥1,311.1bn, which represent 24.9% of total assets. Cash and deposits increased 44.7% year on year to ¥239.9bn, but cash covers only 0.35x of short-term debt, a liquidity-stress indicator. Short-term loans increased 44.3% to ¥692.1bn, while commercial paper increased ¥138.8bn to ¥305.7bn. Short-term debt accounts for 58.9% of interest-bearing debt, creating refinancing risk and a maturity mismatch because readily available cash is limited relative to near-term funding needs. Interest-bearing debt totaled ¥1,176.0bn, with debt-to-equity of 1.93x and debt-to-capital of 39.6%. D/E is below, but close to, the 2.0x aggressive-leverage warning threshold; balance-sheet flexibility is therefore more constrained than the debt-to-capital ratio alone suggests. Interest coverage of 2.81x is a concern because operating profitability provides a limited buffer against higher financing costs or weaker market margins. Total assets increased ¥482.1bn year on year to ¥5,258.0bn, while total liabilities increased ¥642.8bn to ¥3,466.0bn, reducing the equity ratio to 33.5% from 36.0%. Long-term loans increased ¥74.0bn to ¥483.9bn, whereas bonds payable declined ¥10.0bn to ¥100.0bn. Goodwill of ¥131.6bn is modest at 7.3% of equity and 2.5% of assets, limiting goodwill-related balance-sheet risk. Asset-retirement obligations totaled ¥41.6bn, or about 1.2% of total liabilities, which is manageable but relevant for a refining, chemicals and resource-asset operator.

Notable B/S Changes

Cash and deposits: +¥74.1bn (+44.7%) to ¥239.9bn - improved nominal cash reserves, but coverage remains only 0.35x of short-term debt. Short-term loans: +¥212.2bn (+44.3%) to ¥692.1bn - materially higher reliance on near-term borrowing and refinancing markets. Commercial paper: +¥138.8bn (+83.2%) to ¥305.7bn - reinforces the shift toward short-duration funding. Long-term loans: +¥74.0bn (+18.1%) to ¥483.9bn - adds to interest-bearing debt while operating income has weakened. Accounts receivable: +¥98.7bn (+12.1%) to ¥916.0bn - increased capital tied up in customer balances and should be monitored alongside collections. Accounts payable: -¥116.8bn (-14.2%) to ¥707.7bn - reduced supplier financing contributed to higher working-capital funding needs. Total liabilities: +¥642.8bn (+21.2%) to ¥3,466.0bn - liabilities increased faster than assets and equity, contributing to the decline in the equity ratio. Treasury stock: +¥73.2bn reduction in the negative balance (+52.4%) to -¥66.5bn - supports reported equity and per-share measures, though the underlying capital-allocation mechanism should be assessed separately. Property, plant and equipment: +¥135.9bn (+9.1%) to ¥1,509.9bn - reflects the capital intensity of refining, chemicals and resource operations. Goodwill: +¥7.3bn (+5.9%) to ¥131.6bn - acquisition exposure remains modest at 7.3% of equity, limiting impairment concentration risk.

Cash Flow Quality

Dividend Sustainability

The interim dividend was ¥18 per share, and the full-year forecast is ¥36 per share. The disclosed interim payout ratio was 44.1%, based on the ¥18 dividend and interim-period earnings, which is within the stated 60% sustainability benchmark. Based on the full-year EPS forecast of ¥61.24, the planned ¥36 annual dividend implies a forecast dividend payout ratio of approximately 58.8%, close to but still below that benchmark. Dividend capacity is nevertheless sensitive to the required Q4 recovery in operating income, because nine-month earnings include material non-operating and extraordinary gains. The reduction in treasury stock by ¥73.2bn year on year affects equity and per-share metrics, but no cash-flow data are available to assess shareholder distributions beyond the stated dividend. The sustainability of the forecast dividend should therefore be evaluated against achievement of the full-year earnings plan, cash generation from working capital, and the ability to refinance short-term debt at reasonable cost.

Risk Assessment

Business risks include Fuel Oil is the core business by revenue, but its operating income fell 82.1% year on year to ¥12.8bn. Refining margins, crude and product price volatility, inventory valuation effects and domestic fuel-demand trends can therefore cause large earnings swings., Basic Chemicals recorded a ¥12.1bn operating loss, wider than the ¥5.2bn prior-year loss. Persistent weak petrochemical spreads, oversupply and feedstock-cost volatility could delay a return to segment profitability., Resources operating income declined 57.0% to ¥22.6bn. Coal-price volatility, mine operating performance, Australian regulatory requirements and decarbonization-related demand risks remain material., High Functional Materials provides a higher-margin earnings offset, but its ¥390.6bn revenue base is substantially smaller than Fuel Oil and cannot yet fully neutralize commodity-segment volatility., Foreign-exchange gains were ¥8.3bn, equal to 22.7% of operating income. This exceeds the 20% alert threshold and indicates that currency movements can materially affect reported earnings despite operating performance..

Financial risks include Short-term debt represents 58.9% of interest-bearing debt, above the 40% refinancing-risk alert level. The ¥692.1bn short-term loan balance rose 44.3% year on year, increasing dependence on stable bank and commercial-paper markets., Cash-to-short-term-debt is only 0.35x, below the 0.5x liquidity-stress threshold. Although the current ratio is above 1.0x, short-term liquidity depends materially on inventory realization and continued refinancing., Interest coverage is 2.81x, below the 3x caution threshold. A further reduction in operating income or an increase in borrowing costs would reduce debt-service headroom., D/E of 1.93x is close to the 2.0x aggressive-leverage threshold, while the equity ratio declined to 33.5% from 36.0% as liabilities grew faster than equity., Inventory days of 65 exceed the 60-day alert threshold. In an energy and chemicals business, elevated inventory increases exposure to commodity-price declines and potential working-capital absorption..

Key concerns include Low operating efficiency is the highest-priority concern: the 0.6% EBIT margin is far below the 5% caution benchmark and fell 117bp year on year. This reflects severe profit compression in the largest Fuel Oil segment and continued losses in Basic Chemicals., Capital efficiency is weak, with annualized ROIC of 1.4% and annualized ROE of 3.9%. Current returns appear insufficient to provide a large buffer for a capital-intensive operating model and debt load., Reported bottom-line earnings include high one-time items, flagged at 20.4% of net income. In particular, ¥7.9bn of negative-goodwill gain from the Boggabri coal-mine interest acquisition and ¥8.1bn of gain on step acquisitions supported pre-tax income; these items are not recurring operating earnings., The combination of low gross margin at 7.3%, elevated inventory days and a low quick ratio increases vulnerability to abrupt commodity-price moves and working-capital pressure., The full-year operating-income forecast requires a large Q4 recovery, with only 54.0% progress at Q3 versus a standard 75%. Failure to restore Fuel Oil margins or narrow Basic Chemicals losses would place the profit plan and forecast dividend coverage under pressure..

Investment Implications

Key takeaways include The earnings deterioration is primarily operational: operating income fell ¥86.6bn year on year, far exceeding the decline in reported net income because non-operating and extraordinary items partially cushioned the bottom line., High Functional Materials is the most profitable operating segment at a 7.4% margin and delivered year-on-year profit growth, but Fuel Oil and Resources remain the dominant earnings drivers by scale., The balance sheet remains supported by positive working capital and moderate goodwill exposure, but higher short-term funding and weak interest coverage increase sensitivity to funding-market conditions., Forecast delivery depends disproportionately on Q4, particularly recovery in Fuel Oil profitability and containment of Basic Chemicals losses., JGAAP goodwill of ¥131.6bn is not excessive relative to equity, but JGAAP amortization and future impairment assessments remain relevant to acquisition-related earnings analysis..

Metrics to watch include Fuel Oil segment operating income and refining/inventory-margin trends, Basic Chemicals operating loss and petrochemical spread recovery, Q4 operating income required to close the ¥31.3bn gap to full-year guidance, Short-term loans, commercial paper balances, cash-to-short-term-debt coverage and interest coverage, Inventory days and inventory valuation sensitivity to crude and product prices, Foreign-exchange gains or losses relative to operating income, Recurring earnings excluding negative-goodwill, step-acquisition and other extraordinary gains.

Regarding relative positioning, Idemitsu combines a very large, high-turnover Fuel Oil platform with smaller but structurally higher-margin High Functional Materials and Resources businesses. At present, its 0.6% operating margin, 1.4% annualized ROIC and 3.9% annualized ROE indicate weaker capital efficiency than a diversified energy and materials peer would typically seek, while the High Functional Materials margin demonstrates a potentially valuable higher-quality earnings base.
