SUMCO (3436) FY2026 Q1 Earnings Report

Quick View

Executive Summary

For Q1 of the fiscal year ending December 2026, the Company reported a decline in revenue and a shift to operating and net losses. Although the loss幅 has been trending downward from the previous year, profitability has not yet recovered. Revenue was ¥1,014.0B (-1.0% YoY), Operating Income was ¥-52.7B (a shift to a loss from ¥59.9B in the previous year), Ordinary Income was ¥-79.7B (a shift to a loss from ¥48.9B in the previous year), and Net Income attributable to owners of the parent was ¥-84.7B (a shift to a loss from ¥30.5B in the previous year). With the gross profit margin remaining low at 8.3%, the Company was unable to absorb fixed SG&A expenses of ¥137.3B, resulting in an operating loss. As the Company operates a single business—high-purity silicon—demand and capacity-utilization trends have a substantial impact on profitability.

Factors Affecting Earnings

【Revenue】Revenue was ¥1,014.0B, representing an almost flat decline of -1.0% YoY. The Company has a single segment, “high-purity silicon,” and does not disclose a business-by-business breakdown; however, demand and pricing trends for semiconductor silicon wafers are directly reflected in total revenue. The full-year forecast is ¥2,134.0B (+3.9% YoY), and the Q1 progress rate is 47.5%, exceeding the standard progress benchmark of 25%.

【Profit and Loss】Cost of sales was ¥929.4B, and the gross profit margin remained low at 8.3%. As the Company was unable to fully absorb SG&A expenses of ¥137.3B, Operating Income was ¥-52.7B. This represents a significant deterioration from Operating Income of ¥59.9B in the same period of the previous year; however, compared with the full-year forecast of an operating loss of ¥77.0B, performance is trending toward improvement. Non-operating expenses of ¥34.2B, including interest expense of ¥8.1B, exceeded non-operating income of ¥7.3B, causing Ordinary Income to deteriorate further from Operating Income to ¥-79.7B. Following the recognition of income taxes and other taxes of ¥6.9B, consolidated Net Income was ¥-86.5B, while Net Income attributable to owners of the parent widened to ¥-84.7B. In conclusion, the Company reported declining revenue and earnings, with Operating Income, Ordinary Income, and Net Income all shifting into the red.

Segment Analysis

The Group operates in a single segment, “high-purity silicon,” and therefore omits segment-level disclosures. Accordingly, all earnings fluctuations are attributable to supply-demand, pricing, and capacity-utilization trends in this single business, while the risk-mitigation benefits of business diversification are limited.

Key Financial Indicators

【Profitability】The Operating Income margin deteriorated significantly to -5.2% (previous year: +5.8%), while the Net Income margin, based on income attributable to owners of the parent, declined to -8.4% (previous year: +3.0%). The gross profit margin of 8.3% is insufficient to absorb fixed costs. ROE was -1.4%, indicating a substantial decline in capital efficiency following the shift to a loss. 【Cash Quality】Interest expense of ¥8.1B exceeded interest income of ¥3.5B, resulting in negative net non-operating income of ¥-26.9B and indicating that financing costs are weighing on earnings. 【Investment Efficiency】Property, plant and equipment of ¥6,421.6B accounted for 56.2% of total assets, reflecting a capital-intensive business structure. Although investment, including construction in progress, is proceeding ahead of returns, the Company recorded an operating loss in the current period, and the return on invested capital remains low. 【Financial Soundness】The Equity Ratio improved from the previous year to 56.0% (previous year: 51.3%). Net assets of ¥6,404.4B against total assets of ¥11,428.2B indicate a solid capital base. However, interest-bearing debt is substantial, with long-term borrowings of ¥3,301.1B compared with cash and deposits of ¥794.8B. During periods of negative Operating Income, sensitivity to the interest burden is increasing.

Cash Flow Analysis

Although disclosed figures from the cash flow statement could not be confirmed, funding trends can be assessed from changes in the balance sheet. Cash and deposits increased by +¥121.9B to ¥794.8B from ¥672.9B in the previous year. Meanwhile, short-term borrowings stood at ¥435.5B, and long-term borrowings increased to ¥3,301.1B (previous year: ¥3,122.0B). Funding secured through borrowings appears to be one factor behind the increase in cash and deposits. Inventories were ¥269.1B on a finished-goods basis, representing a slight increase from the previous year. Although there has been no significant change in inventory levels, maintaining inventories during an operating loss could place pressure on working capital. Accounts receivable were ¥871.6B, slightly down from ¥899.9B in the previous year, indicating that collections have progressed to some extent.

Quality of Earnings

The loss arose at the operating level and was not attributable to extraordinary gains or losses. Accordingly, the deterioration in earnings quality should be viewed as recurring and primarily driven by worsening profitability in the core business. Non-operating expenses of ¥34.2B include interest expense of ¥8.1B and represent recurring financing costs. Foreign exchange gains of ¥2.1B were recorded as part of non-operating income, but the amount was limited and had only a minor impact on earnings. Comprehensive Income was ¥-74.1B, including ¥-70.9B attributable to owners of the parent. The difference from Net Income of ¥-84.7B was attributable to foreign currency translation adjustments of +¥12.6B, with changes in the valuation of overseas assets slightly increasing Comprehensive Income. Income taxes and other taxes of ¥6.9B were recognized despite a loss before tax of ¥-79.7B, resulting in a negative effective tax rate. This indicates that accrual-related factors, such as the treatment of deferred tax assets, further worsened final earnings.

Earnings Forecast and Guidance

The full-year earnings forecast comprises Revenue of ¥2,134.0B (+3.9% YoY), an Operating Loss of ¥-77.0B, and an Ordinary Loss of ¥-144.0B, representing a consistent loss forecast since the beginning of the fiscal year. As of Q1, the progress rate for Revenue was 47.5%, indicating solid progress. However, the operating loss had already reached 68.5% of the full-year forecast, while the ordinary loss had reached 55.3%. Therefore, improvement in profitability over the remaining three quarters is a prerequisite for achieving the plan. The earnings forecast was revised during the current quarter, and demand and pricing trends toward the second half of the fiscal year will be key to achieving the plan.

Shareholder Returns

The dividend per share for the fiscal year ending December 2026 has not yet been determined, and the Company states that it will promptly disclose the amount once disclosure becomes possible. During the current quarter, Net Loss attributable to owners of the parent was ¥84.7B, and EPS was ¥-24.22, reflecting a loss. Accordingly, evaluation based on the Payout Ratio is not currently applicable. The dividend forecast was also revised, and the future dividend level is expected to depend on the extent of earnings recovery.

Risk Factors

1. Single-business structure risk: The Company operates a single segment consisting solely of the high-purity silicon business. Changes in capital expenditure, selling prices, and capacity-utilization rates among semiconductor memory and logic customers directly affect total Revenue and earnings. The low gross profit margin of 8.3% and Operating Income margin of -5.2% support this structural vulnerability.

2. Insufficient interest coverage risk: Because Operating Income is a loss of ¥-52.7B, the Company is unable to cover interest expense of ¥8.1B through Operating Income. Interest-bearing debt is substantial, centered on long-term borrowings of ¥3,301.1B. If losses continue, concerns arise regarding the impact on refinancing terms and funding costs.

3. Recovery risk for large-scale capital investment: Property, plant and equipment of ¥6,421.6B, including construction in progress of ¥902.8B, accounts for 56.2% of total assets. If the recovery in demand for advanced wafers is slower than expected, the risks of excess capacity, an extended investment payback period, and the inability to absorb depreciation expenses will increase.

Key Points in the Earnings Report

1. Although the Operating Loss and Net Loss narrowed year on year, the Operating Income margin of -5.2% and Net Income margin of -8.4% remain below the breakeven point, indicating that profitability is still in the process of recovery.

2. Property, plant and equipment accounts for 56.2% of total assets, and large-scale investment, including construction in progress of ¥902.8B, is proceeding ahead of returns. While operating leverage will work during a recovery in the semiconductor cycle, a delayed recovery would result in fixed costs and depreciation expenses becoming a burden.

3. As of Q1, the operating loss had reached 68.5% of the full-year forecast, meaning that achievement of the full-year plan depends on improved profitability from the second half onward. The year-end dividend forecast remains undetermined, and progress in earnings recovery will influence the Company’s future shareholder-return policy.

Theoretical Share Price (Reference Value)

Sensitivity: ¥1,241–¥1,312 at cost of equity ±1%, and ¥1,258–¥1,287 at ω±0.1.

Notes:

• As 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 relative to the full-year forecast.
• Because net assets include non-controlling interests, the theoretical value may be calculated somewhat higher.

AI Financial Analysis

Executive Summary

SUMCO’s FY2026 Q1 result was weak, with a modest sales decline translating into a substantial operating and net loss as gross profitability deteriorated sharply. Revenue was ¥101.4bn, down 1.0% YoY from ¥102.5bn. Gross profit fell to ¥8.5bn from ¥19.0bn in the prior-year quarter. The gross margin compressed by 1,021bp YoY to 8.3% from 18.6%. SG&A expense increased 5.5% YoY to ¥13.7bn despite lower revenue. Consequently, operating income swung to a ¥5.3bn loss from a ¥6.0bn profit, and the operating margin deteriorated by 1,105bp to negative 5.2%. Ordinary income was a ¥8.0bn loss, reflecting the operating loss and ¥3.4bn of non-operating expense, including ¥0.8bn of interest expense. Net income attributable to owners was a ¥8.5bn loss, versus a ¥3.0bn profit a year earlier, equivalent to EPS of negative ¥24.22. The net margin was negative 8.3%, down 1,193bp from positive 3.6% in FY2025 Q1. The loss was driven principally by the collapse in gross profit rather than revenue contraction, indicating substantial sensitivity to wafer pricing, product mix, utilization and fixed-cost absorption. Interest income of ¥0.4bn and FX gains of ¥0.2bn provided only limited offsets to financing costs. The balance sheet retains substantial liquidity, with a 335.7% current ratio, ¥79.5bn of cash and deposits, and cash equal to 1.82 times short-term debt. However, the earnings recovery requirement is significant because the company carries ¥373.7bn of interest-bearing debt while EBIT is negative. The full-year forecast calls for revenue of ¥213.4bn and an operating loss of ¥7.7bn. Q1 revenue has already reached 47.5% of the full-year sales forecast, well above the normal 25% quarterly run-rate, while the Q1 operating loss represents 68.5% of the projected full-year loss. This profile implies that management expects a material improvement in profitability through the remaining quarters, rather than a comparable improvement in sales alone. The FY2026 year-end dividend remains undetermined, appropriately placing capital preservation and the timing of semiconductor-cycle recovery at the center of shareholder-return expectations.

Profitability Analysis

Annualized DuPont ROE was negative 5.3%, comprising a negative 8.3% net profit margin, 0.355x asset turnover, and 1.78x financial leverage. The dominant negative factor was profitability: the net margin moved from positive 3.6% in FY2025 Q1 to negative 8.3%, whereas the quarter’s revenue decline was only 1.0%. Gross margin compression to 8.3% from 18.6% was the central operational driver, reducing gross profit by ¥10.5bn. SG&A increased to ¥13.7bn from ¥13.0bn while sales declined, raising the SG&A-to-sales ratio to 13.5% from 12.7% and worsening negative operating leverage. Operating income therefore deteriorated by ¥11.3bn YoY, from a ¥6.0bn profit to a ¥5.3bn loss. Annualized asset turnover of 0.355x remains low, consistent with the capital-intensive silicon-wafer manufacturing model and the currently subdued revenue base relative to ¥1,142.8bn of assets. Financial leverage of 1.78x amplified the negative return on equity but remains moderate in balance-sheet terms, supported by a 0.78x debt-to-equity ratio. The negative EBIT margin of 5.2% and ROIC of negative 2.3% indicate that operating assets are currently generating returns below funding costs. The five-factor DuPont tax burden of 1.063 and interest burden of 1.511 are mechanically distorted by losses and should not be interpreted as favorable tax or financing efficiency. The priority for profitability is a recovery in gross margin through improved capacity utilization, pricing, mix and fixed-cost absorption; revenue growth without this margin normalization would not restore acceptable returns.

Growth Assessment

Revenue declined only 1.0% YoY in Q1, but profit performance shows that current growth quality is weak because the revenue base is not covering production and fixed costs adequately. The 55.5% decline in gross profit far exceeded the sales movement, signaling adverse unit economics rather than a simple volume shortfall. Accounts receivable declined 3.2% YoY to ¥87.2bn, broadly consistent with the low-growth revenue environment. Management’s FY2026 forecast assumes 3.9% full-year revenue growth to ¥213.4bn, and Q1 progress was 47.5% versus a normal 25% benchmark. The unusually high Q1 sales progress suggests the forecast embeds a weaker revenue run-rate in subsequent quarters or reflects expected timing effects in shipments. In contrast, the Q1 operating loss of ¥5.3bn equals 68.5% of the full-year operating-loss forecast of ¥7.7bn, indicating that management expects earnings to improve materially after Q1. Q1 ordinary loss and loss attributable to owners respectively represent 55.3% and 55.0% of the respective full-year forecast losses. For a high-purity silicon single-segment business, the durability of recovery will depend more on semiconductor-wafer demand, customer inventory normalization, utilization rates and pricing than on nominal sales growth alone. Construction in progress declined 26.9% YoY to ¥90.3bn while machinery increased 4.7% to ¥324.8bn, consistent with the progression of an existing investment pipeline into productive assets. This creates a need for demand recovery and utilization improvement to support returns on the expanded manufacturing asset base.

Financial Health

Liquidity is strong on reported balance-sheet measures. Current assets of ¥464.2bn exceeded current liabilities of ¥138.3bn, producing working capital of ¥326.0bn and a current ratio of 335.7%. The quick ratio was also robust at 316.3%, indicating that short-term obligations are covered without relying on inventory liquidation. Cash and deposits were ¥79.5bn, up 18.1% YoY, and covered short-term loans of ¥43.6bn by 1.82x. Interest-bearing debt totaled ¥373.7bn, comprising ¥43.6bn of short-term loans and ¥330.1bn of long-term loans. The short-term debt ratio was 11.7%, so debt maturity is concentrated in long-term borrowings rather than creating an immediate maturity mismatch. Debt-to-equity was 0.78x and debt-to-capital was 36.8%, both within conservative-to-moderate balance-sheet benchmarks. Total equity was ¥640.4bn, equivalent to 56.0% of total assets, while the capital adequacy ratio was 49.8%. The central financial-health concern is debt service capacity rather than near-term liquidity: interest coverage was negative 6.49x because EBIT was a ¥5.3bn loss against ¥0.8bn of interest expense. This negative coverage means operating earnings currently do not service financing costs, making the forecast profitability recovery important to maintaining balance-sheet flexibility. Net defined benefit liability was ¥20.2bn, representing an additional fixed long-term obligation, though it is modest relative to total equity.

Notable B/S Changes

Construction in progress: -¥33.1bn (-26.9% YoY) to ¥90.3bn - indicates a substantial portion of the investment pipeline has been completed, deferred or otherwise moved out of CIP; subsequent utilization and return generation are important. Machinery and equipment: +¥14.6bn (+4.7% YoY) to ¥324.8bn - reflects continued expansion of productive manufacturing assets and reinforces the need for utilization recovery. Cash and deposits: +¥12.2bn (+18.1% YoY) to ¥79.5bn - improves immediate liquidity and supports coverage of ¥43.6bn in short-term loans. Provision for bonuses: +¥1.7bn (+78.3% YoY) to ¥4.0bn - a notable increase in current obligations that should be monitored alongside profitability and personnel-cost discipline.

Cash Flow Quality

Dividend Sustainability

The FY2026 year-end dividend per share is undetermined. With Q1 EPS of negative ¥24.22 and a full-year EPS forecast of negative ¥44.04, a conventional dividend payout ratio is not meaningful. The prior-year Q1 dividend per share was ¥10.00, but the current loss-making period and management’s undecided dividend stance indicate that any future distribution decision will depend on the pace of profit recovery, liquidity preservation and funding requirements for the capital-intensive production base.

Risk Assessment

Business risks include Semiconductor-cycle and silicon-wafer pricing risk is the highest operational risk: a 1.0% sales decline coincided with a 1,021bp gross-margin decline, demonstrating high exposure to utilization and fixed-cost absorption., Inventory-cycle risk is elevated. Annualized DIO of 251 days exceeds the 90-day warning threshold, indicating a long capital commitment in inventory and potential exposure to demand changes, mix shifts or valuation pressure., Collection efficiency requires monitoring, with annualized DSO of 78 days above the 60-day warning threshold. Combined with high inventory days, this contributes to a 292-day annualized cash conversion cycle., The company operates in a single high-purity silicon segment, concentrating exposure to semiconductor foundry and memory investment cycles, customer purchasing adjustments and competitive capacity additions., Manufacturing execution risk remains material because PPE represents 56.2% of total assets. Returns depend on maintaining high utilization of specialized wafer-production equipment and successfully converting investment pipeline assets into productive capacity., Foreign-exchange exposure remains relevant for an export-oriented semiconductor-materials business; Q1 included ¥0.2bn of FX gains, although this did not offset the operating loss..

Financial risks include Debt-service risk is elevated: interest coverage was negative 6.49x, as negative EBIT does not cover ¥0.8bn of quarterly interest expense. The risk is mitigated by strong short-term liquidity but requires a restoration of operating profit., Interest-bearing debt of ¥373.7bn is significant relative to the current loss-making earnings base. Debt-to-equity of 0.78x and debt-to-capital of 36.8% remain manageable, but these ratios could weaken if losses persist., Annualized ROIC of negative 2.3% is below the 5% warning threshold, indicating that capital employed is currently not earning an adequate return., Total equity declined ¥7.3bn YoY to ¥640.4bn, reflecting losses and other comprehensive income movements, although the 49.8% capital adequacy ratio continues to provide a meaningful loss-absorption buffer..

Key concerns include The most material issue is low operating efficiency: EBIT margin was negative 5.2%, versus the 5% concern threshold, following an 1,105bp YoY operating-margin deterioration., Low gross margin of 8.3%, below the 20% alert threshold, is the immediate cause of the operating loss and highlights the need for utilization and pricing recovery., The 292-day annualized cash conversion cycle is substantially above the 120-day warning level. DSO of 78 days and DIO of 251 days suggest that working capital could constrain cash generation during a prolonged downturn., Forecast execution risk is high because Q1 already accounts for 68.5% of the full-year operating-loss forecast, requiring a marked earnings improvement across the remaining quarters., The Q1 loss included a ¥0.7bn income-tax expense despite a pre-tax loss, contributing to the net loss; this increases sensitivity of attributable earnings to tax recognition and jurisdictional profit mix..

Investment Implications

Key takeaways include Q1 sales were broadly stable, but gross margin compression caused a shift from ¥6.0bn operating profit to a ¥5.3bn operating loss., Annualized ROE of negative 5.3% and annualized ROIC of negative 2.3% indicate materially subpar capital returns at the current point of the cycle., Liquidity is a counterbalance to weak earnings, supported by a 335.7% current ratio, ¥79.5bn of cash and deposits, and long-term concentration of debt maturities., The principal analytical question is whether utilization, wafer pricing and fixed-cost absorption can recover sufficiently to narrow the gap between Q1 earnings and the full-year loss forecast., The undetermined FY2026 dividend makes future shareholder returns dependent on earnings normalization and balance-sheet priorities..

Metrics to watch include Gross margin and operating margin, particularly evidence of recovery from 8.3% and negative 5.2%, respectively., Operating-income progress against the FY2026 forecast operating loss of ¥7.7bn., Annualized DIO, DSO and cash conversion cycle, currently 251 days, 78 days and 292 days., Interest coverage and the relationship between EBIT recovery and ¥373.7bn of interest-bearing debt., Revenue run-rate relative to the ¥213.4bn full-year forecast and indications of wafer demand, utilization and pricing., Construction-in-progress conversion and returns on the ¥642.2bn PPE base..

Regarding relative positioning, SUMCO has a capital-intensive, single-product semiconductor-materials profile in which modest revenue movements can produce large margin and return swings. Relative balance-sheet liquidity is solid, but current earnings efficiency is weak: negative EBIT, negative annualized ROE and ROIC, low gross margin, and a long working-capital cycle make the company more dependent on a cyclical recovery in wafer utilization and pricing than a diversified or asset-light peer.
