Executive Summary
For the cumulative Q2 of the fiscal year ending December 2026, Bridgestone reported higher revenue and higher profits, demonstrating quality earnings growth in which the increase in operating income significantly outpaced revenue growth. Revenue was ¥2,3216.7B (+9.7% YoY), operating income was ¥2802.3B (+70.4%), profit before tax was ¥2746.0B (+76.7%), and net income attributable to owners of the parent was ¥2,062.5B (+78.5%). All segments achieved higher revenue and higher profits. Improvements in raw material costs and the effects of restructuring in Europe drove margin expansion, while cost increases associated with the situation in the Middle East and U.S. tariffs are expected to become more pronounced in the second half.
Factors Affecting Performance
【Revenue】Revenue was ¥2,3216.7B, representing a +9.7% YoY increase. The Americas (+11%), Europe, Middle East and Africa (+11%), and Asia and Oceania (+13%) led growth, while Japan also posted a +5% increase, resulting in higher revenue across all regions.
【Profit and Loss】Operating income was ¥2802.3B, up +70.4% YoY, and the operating margin improved to 12.1% from 7.8% in the prior year, an improvement of approximately 4.3pt. The Japan segment’s margin of 17.9% (+4.3pt) and significant earnings improvement in Europe contributed to the result, with improved raw material costs and restructuring effects serving as key drivers. Profit before tax was ¥2746.0B and net income was ¥2103.2B (¥2,062.5B attributable to owners of the parent, +78.5% YoY), both showing growth broadly in line with operating income. There was no significant divergence, and one-time factors were limited. In conclusion, the Company achieved higher revenue and higher profits, while the profit growth rate significantly exceeding the revenue growth rate indicates a growth phase accompanied by improved profitability.
Segment Analysis
The Americas generated the largest revenue at ¥11,353B and is positioned as the core business. Its operating margin was 9.1% (+0.1pt), essentially flat; while its large scale supported absolute earnings, its contribution to margin improvement was limited. Japan generated revenue of ¥6,344B but recorded the highest margin among all segments at 17.9% (+4.3pt). Strong performance of the new FINESSA product and improved raw material costs contributed significantly to overall profit growth. Europe, the Middle East and Africa generated revenue of ¥4,585B, with its margin improving substantially to 7.4% (+3.0pt) due to restructuring and rebuilding effects; it recorded the largest margin increase from the prior year. Asia, Oceania, India and China generated revenue of ¥2,780B, with the margin declining slightly to 11.2% (-0.7pt). Among the segments, Japan posted the highest margin, while Europe recorded the largest improvement, indicating that profitability improvements were led by Japan and Europe.
Key Financial Indicators
Profitability: ROE was 5.5%, and the operating margin was 12.1% (improved from 7.8% in the prior year).
Cash flow quality: Operating CF of ¥3,418.3B was 1.6 times net income of ¥2,103.2B, indicating strong cash backing for earnings.
Investment efficiency: Free CF was positive at ¥2,214.8B against capital expenditures of ¥1,308.1B.
Financial soundness: The equity ratio was 64.1% (63.7% in the prior year). Cash and deposits of ¥7,917.3B exceeded total bonds and borrowings of ¥5,600.7B, indicating a conservative financial position.
Cash Flow Analysis
Operating CF was ¥3,418.3B, or 1.6 times net income, generating cash at a pace exceeding earnings growth. Investing CF was -¥1,203.4B, primarily due to capital expenditures of ¥1,308.1B. Financing CF was -¥1,581.5B, with dividend payments of ¥733.8B and share repurchases of ¥1,092.8B representing the main cash outflows. FCF was ¥2,214.8B (operating CF - capital expenditures), sufficient to cover total shareholder returns of ¥1,826.6B. Cash generation is considered strong, and cash backing during the earnings growth phase is favorable.
Quality of Earnings
Net income was ¥2,103.2B against profit before tax of ¥2,746.0B, after deducting income taxes and other taxes of ¥644.4B (effective tax rate of 23.5%). The difference between the two is commensurate with the tax burden, with no particular one-time factors identified. Financial expenses of ¥178.1B exceeded financial income of ¥115.5B on a net basis, but the impact on profitability was limited as the amount was small relative to revenue. Operating CF exceeded net income by 1.6 times, indicating limited accruals and good earnings quality.
Earnings Forecast and Guidance
Progress toward the full-year forecast (revenue of ¥4,5000B and net income attributable to owners of the parent of ¥3,400B) was 51.6% for revenue and 60.7% for net income. Net income progress was 10.7pt above the standard first-half progress rate of 50%. There was no revision to the earnings forecast during the quarter, and the full-year outlook remains unchanged. In the second half, raw material cost increases associated with the situation in the Middle East are expected to materialize (approximately ¥700B for the full year, of which slightly more than ¥600B is expected in the second half). Accordingly, it should be noted that the strong first-half progress may not continue at the same pace in the second half.
Shareholder Returns
The Q2 dividend was ¥60.00 per share, and the full-year dividend forecast is ¥125.00 (scheduled to increase from ¥115 in the prior year). The payout ratio, calculated based on net income reported for the first half, is at an appropriate level. In addition to dividend payments of ¥733.8B, the Company conducted share repurchases of ¥1,092.8B, resulting in a total return ratio of approximately 88.6% relative to net income attributable to owners of the parent. The ¥1,500B share repurchase program had reached approximately 87% completion as of the end of July, and total shareholder returns were funded within FCF of ¥2,214.8B.
Catalysts
【Short term】The extent to which raw material cost increases associated with the situation in the Middle East (slightly more than ¥600B) can be absorbed in the second half, and the development of the impact of U.S. tariffs. 【Long term】Progress in initiatives to strengthen product competitiveness, the global portfolio and the brand under the management policy of reclaiming the global No.1 position toward the 100th anniversary of the Company’s founding in 2031.

Risk Factors
-
Working capital accumulation: Inventory days (annualized) are approximately 122 days, receivable days are approximately 89 days, and the CCC is approximately 137 days (172 days based on the PDF, +1 day YoY). All exceed typical manufacturing industry levels. During periods of slowing demand, this could lead to impairment losses and pressure to offer discounts.
-
Rising raw material costs: Raw material and other costs related to the situation in the Middle East are expected to materialize at slightly more than ¥600B in the second half. If market prices for natural rubber (TSR20 218¢/kg) and crude oil (WTI 93$/bbl) continue to rise, maintaining the improved margin achieved during the current period will be a challenge.
-
Foreign exchange and tariff impacts: The impact of U.S. tariffs for the cumulative Q2 was ¥250B YoY (in line with the plan), while fluctuations in foreign exchange rates (USD/JPY ¥158) could also affect the translation of overseas business earnings.
Key Earnings Highlights
-
The operating margin improved by approximately 4.3pt, from approximately 7.8% in the same period of the prior year to 12.1%, and all segments achieved higher revenue and higher profits. Japan (17.9%) and Europe (7.4%, +3.0pt) recorded particularly large improvements and were the primary drivers of profitability enhancement.
-
While the full-year forecast remains unchanged, cost increases of slightly more than ¥600B arising from the situation in the Middle East are planned for the second half. Whether the strong first-half progress (60.7% for net income) can be maintained in the second half will depend on the ability to pass through costs and the sustainability of restructuring effects.
-
Operating CF was 1.6 times net income, indicating strong cash generation. However, the tendency toward a lengthening CCC is a structural issue requiring monitoring from the perspective of working capital efficiency.

AI Financial Analysis
Executive Summary
Bridgestone delivered a strong FY2026 Q2 earnings outcome, with substantial operating-profit and attributable-profit growth on solid revenue expansion. Revenue increased 9.7% year on year to ¥2,321.7bn. Operating income rose 70.4% to ¥280.2bn, materially outpacing sales growth. Profit attributable to owners increased 78.5% to ¥206.2bn. Gross profit increased to ¥922.7bn from ¥816.0bn in the prior-year period. The gross margin expanded by 110bp to 39.7%, indicating improved pricing, mix, manufacturing cost absorption, or a combination of these factors. The operating margin expanded by 430bp to 12.1% from 7.8% a year earlier. Net margin rose by 340bp to 8.9% from 5.5%. This demonstrates meaningful operating leverage, as SG&A rose 9.6%, broadly in line with revenue and far below gross-profit growth. Net income was well supported by cash generation: operating cash flow was ¥341.8bn and equalled 1.66x attributable net income. Free cash flow was robust at ¥221.5bn after ¥130.8bn of capital expenditure. However, working-capital efficiency remains the principal operational issue, with annualized receivable days of 89, inventory days of 122, and a cash-conversion cycle of 137 days. Inventories rose 5.6% year on year to ¥935.2bn, while trade receivables increased 4.1% to ¥1,137.7bn. The balance sheet remains conservatively capitalized, with a 64.1% equity ratio and a reported debt-to-equity ratio of 0.54x. Full-year revenue progress is slightly ahead of the normal first-half run rate, while attributable-profit progress is substantially ahead of it. The FY2026 forecast has not been revised, suggesting management retains caution over second-half demand, input costs, foreign exchange, or regional market conditions. The ¥60 interim dividend and continuing ¥109.3bn share repurchase demonstrate active shareholder distributions, supported by first-half free cash flow. Overall, the first-half result strengthens the earnings base, but sustained improvement in inventory and receivable turnover is necessary to validate the durability of cash returns and margins.
Profitability Analysis
Annualized DuPont ROE is 10.8%, comprising an 8.9% net profit margin, 0.787x asset turnover, and 1.54x financial leverage. The largest positive change is profitability rather than leverage: the operating margin expanded 430bp year on year to 12.1%, while the balance-sheet equity ratio improved modestly to 64.1% from 63.7%. Gross margin increased 110bp to 39.7%, and the much larger operating-margin expansion indicates disciplined overhead absorption in addition to gross-profit improvement. Revenue growth of 9.7% generated a 70.4% increase in operating income, evidencing strong operating leverage. SG&A increased 9.6% to ¥642.6bn, essentially matching revenue growth and remaining well below the 13.1% increase in gross profit. Accordingly, there is no indication from the available figures that SG&A inflation is eroding the earnings recovery. The tax burden was 0.751 and the effective tax rate was 23.5%, both consistent with a normal tax profile. The interest burden was 0.980, as finance costs of ¥17.8bn were modest relative to EBIT of ¥280.2bn. Finance income of ¥11.6bn offset much of finance cost, leaving limited financing drag on pre-tax income. Other income of ¥14.4bn was substantially offset by other expenses of ¥14.3bn, so operating-profit conversion into pre-tax profit was largely clean. Equity-method investment income was only ¥0.6bn and did not materially drive group earnings. IFRS accounting means goodwill is subject to impairment testing rather than systematic amortization, making operating income broadly comparable without a JGAAP goodwill-amortization adjustment. Goodwill represents only 4.4% of equity and 2.8% of assets, limiting M&A-accounting distortion and goodwill impairment sensitivity. The 10.8% annualized ROE is in the good benchmark range, although it remains below the >15% level generally associated with excellent capital returns. Further ROE improvement depends primarily on maintaining the current margin recovery and improving asset turnover through better inventory and receivable efficiency.
Growth Assessment
First-half revenue growth of 9.7% and operating-income growth of 70.4% indicate that the earnings recovery is materially faster than top-line expansion. Gross profit rose 13.1%, confirming that the improvement was not solely attributable to higher sales volume. Attributable net income rose 78.5%, slightly faster than operating income, supported by limited net finance-cost burden and the absence of a material other-income contribution. Revenue reached 51.6% of the ¥4,500.0bn full-year forecast, 1.6 percentage points above the standard 50% first-half progress rate. Attributable profit reached 60.7% of the ¥340.0bn full-year forecast, 10.7 percentage points above the standard first-half rate. This profit-progress outperformance is notable because the full-year forecast was maintained rather than raised. The maintained forecast implies a lower second-half earnings pace than the first half, with approximately ¥133.8bn of attributable profit required in H2 versus ¥206.2bn delivered in H1. The implied full-year net margin is approximately 7.6%, below the 8.9% achieved in H1. This conservatism may reflect management’s expectation of normalization in volume, pricing, raw-material costs, foreign exchange, or regional demand conditions. The company remains a capital-intensive global manufacturer, with PPE of ¥1,856.0bn, or 31.4% of total assets, making plant utilization and manufacturing cost absorption important determinants of margin sustainability. Inventory of ¥935.2bn, equivalent to 15.8% of assets, requires monitoring as an indicator of demand alignment and production planning. Continued conversion of the operating-margin recovery into cash flow, rather than further working-capital investment, will be the key confirmation of sustainable growth.
Financial Health
Financial health is solid. Current assets were ¥3,024.7bn, while derived current liabilities were approximately ¥1,086.1bn, producing a current ratio of about 2.78x. This is well above the 1.0x warning threshold and indicates no apparent near-term liquidity mismatch. Derived working capital was approximately ¥1,938.6bn. Cash and cash equivalents were ¥791.7bn, up from ¥713.8bn a year earlier. The reported debt-to-equity ratio of 0.54x is conservative and well below the 2.0x level that would indicate aggressive leverage. Bonds and borrowings totalled ¥560.1bn, comprising ¥78.3bn current and ¥481.7bn non-current. Lease liabilities totalled ¥340.7bn, comprising ¥70.1bn current and ¥269.7bn non-current. The current portions of borrowings and lease liabilities totalled ¥148.4bn, comfortably covered by cash and current assets. Total liabilities represented 35.0% of total assets, while equity represented 65.0%, consistent with a resilient capital structure. Right-of-use assets of ¥310.8bn and lease liabilities of ¥340.7bn represent meaningful contractual obligations, but their scale is manageable relative to equity of ¥3,838.7bn and operating cash flow of ¥341.8bn. The net defined-benefit liability was ¥127.2bn and should remain under review as a long-duration obligation. Treasury stock’s carrying balance changed by ¥159.9bn year on year, from negative ¥433.9bn to negative ¥274.0bn, a 36.9% movement that materially affected the composition of equity. This movement occurred alongside ¥109.3bn of first-half treasury-share purchases, making treasury-share activity and its treatment within equity important to monitor. Goodwill of ¥168.0bn and intangible assets of ¥199.3bn are modest relative to total assets and equity, reducing balance-sheet dependence on acquired intangible values.
Notable B/S Changes
Treasury stock: +¥159.9bn year on year (negative balance narrowed from ¥433.9bn to ¥274.0bn; +36.9%) - material change in the equity structure. This should be assessed alongside ¥109.3bn of first-half treasury-share purchases and ongoing shareholder-return policy. Inventories: +¥49.8bn year on year (+5.6%) to ¥935.2bn - elevated stockholding is consistent with the 122-day annualized DIO alert and increases demand, obsolescence, and cash-conversion sensitivity. Bonds and borrowings, non-current: +¥89.4bn year on year (+22.8%) to ¥481.7bn - the increase remains manageable given the 64.1% equity ratio and reported D/E of 0.54x. Cash and cash equivalents: +¥77.9bn year on year (+10.9%) to ¥791.7bn - liquidity improved despite capital expenditure, dividends, and buybacks. Assets held for sale: -¥14.9bn year on year (-51.9%) to ¥13.8bn - indicates a reduced balance of assets designated for disposal.
Cash Flow Quality
Cash-flow quality was strong in FY2026 Q2. Operating cash flow was ¥341.8bn, exceeding attributable net income of ¥206.2bn by 1.66x. This is well above the 0.8x quality-warning threshold and indicates that reported profit was converted into cash effectively. The accruals ratio was negative 2.3%, also supportive of earnings quality. Free cash flow was ¥221.5bn after capital expenditure of ¥130.8bn. Operating cash flow increased 22.5% year on year, compared with 78.5% attributable-profit growth, so cash flow improved strongly but did not match the rate of accounting-profit growth. Working-capital movements were a cash outflow overall: inventories consumed ¥29.6bn, receivables consumed ¥11.7bn, other working-capital changes consumed ¥49.4bn, and payables provided only ¥8.0bn. The inventory build and receivable outflow are not evidence of earnings manipulation given OCF exceeded net income, but they constrain cash conversion and warrant active monitoring. The quality alert for annualized DSO of 89 days is material because it is above both the 60-day warning level and the manufacturing efficiency benchmark; slower collection raises customer-credit and cash-conversion risk. The quality alert for annualized DIO of 122 days is material because it exceeds the 90-day warning level and also breaches the more stringent 60-day manufacturing benchmark. The duplicated high-inventory-days alerts therefore point to the same core issue: elevated stockholding can signal weaker sell-through, supply-chain buffers, unfavorable product mix, or rising obsolescence risk. The 137-day annualized cash-conversion cycle also exceeds the 120-day warning threshold, reflecting the combined burden of receivables and inventories despite supplier financing. For a tire manufacturer, inventory discipline is particularly important because raw-material price fluctuations, replacement-demand cycles, OEM production schedules, and product specifications can quickly affect stock valuation and turnover. Capex represented 5.6% of first-half revenue, within the typical 3-8% manufacturing range, and FCF remained positive after this investment. Cash flow therefore supports the current earnings performance, but a reduction in DSO, DIO, and the cash-conversion cycle would materially strengthen the quality and repeatability of free-cash-flow generation.
Dividend Sustainability
The FY2026 Q2 dividend is ¥60 per share. Based on first-half EPS of ¥163.30, the calculated interim payout ratio is 38.8%, which is comfortably below the 60% sustainability benchmark. First-half free cash flow of ¥221.5bn covered the estimated interim dividend requirement by 2.77x. The full-year dividend forecast is ¥125 per share, implying a remaining year-end dividend of ¥65 per share. Against forecast EPS of ¥270.87, the forecast dividend payout ratio is approximately 46.1%, which remains conservative. Dividend payments to owners in the first half were ¥73.4bn, below operating cash flow and free cash flow. Share repurchases were ¥109.3bn, in addition to dividends. On a first-half cash basis, dividends plus share repurchases totalled approximately ¥182.7bn, equivalent to an estimated total return ratio of 88.6% of attributable net income. This is below 100%, although it is materially higher than the dividend-only payout ratio and leaves less room for a deterioration in working-capital cash flow. The combined first-half distributions were also covered by first-half FCF, leaving approximately ¥38.7bn after dividends and buybacks. The balance sheet and cash position provide additional flexibility, with ¥791.7bn of cash and a 64.1% equity ratio. Dividend sustainability is therefore well supported by current earnings, FCF, and capitalization. The principal condition for sustaining both dividends and buybacks is preservation of FCF after inventory, receivable, and capital-investment requirements.
Risk Assessment
Business risks include Working-capital risk is the highest operational concern: annualized DSO of 89 days, DIO of 122 days, and a 137-day cash-conversion cycle are all above stated warning thresholds. The impact is potentially significant because slower collections and elevated inventories can absorb cash even if reported margins remain strong., Tire-industry demand is exposed to global OEM vehicle production, replacement-market volumes, freight activity, and consumer mobility. A second-half slowdown would be particularly relevant because first-half attributable profit already represents 60.7% of the maintained full-year forecast., Raw-material and energy-cost volatility is an industry-specific risk for tire manufacturing. The first-half margin recovery may be difficult to preserve if rubber, petrochemical-derived inputs, steel cord, logistics, or energy costs rise faster than pricing can adjust., Inventory risk is elevated due to 122 days of stockholding. A deterioration in demand, production mix, or regional conditions could increase markdown, obsolescence, or under-absorption risk., Foreign-exchange translation materially supported comprehensive income, with exchange differences of ¥928.5bn? Wait, exchange differences were ¥92.9bn, contributing to other comprehensive income of ¥95.4bn. This creates equity volatility even though it does not directly determine operating income..
Financial risks include Leverage risk is limited at present, with a reported debt-to-equity ratio of 0.54x and 64.1% equity ratio, but lease liabilities of ¥340.7bn remain contractual fixed obligations., Treasury-share activity is sizeable: ¥109.3bn of buybacks in H1 increased cash-distribution requirements alongside ¥73.4bn of dividends. If free cash flow weakens, the pace of repurchases could reduce financial flexibility., Defined-benefit obligations of ¥127.2bn create sensitivity to discount rates, asset returns, and actuarial assumptions., The maintained full-year forecast despite above-normal first-half profit progress introduces risk of a material earnings deceleration in H2..
Key concerns include Prioritize whether inventory days decline from 122 days and whether receivable days improve from 89 days; these are the clearest indicators of cash-flow sustainability., Monitor whether the 12.1% operating margin can be sustained as the full-year plan implies a more moderate second-half earnings pace., Monitor total shareholder returns, not only the dividend payout ratio, because buybacks materially increase the aggregate cash commitment., Monitor treasury-stock movements and their effect on equity per share and capital-allocation discipline., Goodwill risk is low relative to peers and to the balance sheet, as goodwill is only 4.4% of equity; impairment is not a central current concern..
Investment Implications
Key takeaways include Revenue increased 9.7%, while operating income and attributable profit increased 70.4% and 78.5%, respectively, showing a sharp profitability recovery., Operating margin expanded 430bp to 12.1%, supported by a 110bp increase in gross margin and controlled SG&A growth., Annualized ROE of 10.8% is good, with performance driven by margin improvement rather than higher leverage., OCF/attributable net income of 1.66x, negative 2.3% accruals, and ¥221.5bn FCF support the quality of reported earnings., High DSO, DIO, and cash-conversion-cycle metrics are the principal constraints on the otherwise strong cash-flow profile., The balance sheet is robust, with a 64.1% equity ratio, 0.54x reported D/E, and cash of ¥791.7bn., The FY dividend plan appears sustainable, while the combined dividend-and-buyback commitment requires ongoing FCF discipline..
Metrics to watch include Operating margin versus the 12.1% H1 level and the implied lower second-half margin embedded in unchanged guidance, Annualized receivable days, currently 89 days, Annualized inventory days, currently 122 days, Annualized cash-conversion cycle, currently 137 days, Inventory balance of ¥935.2bn and receivable balance of ¥1,137.7bn, Free cash flow after ¥130.8bn of H1 capex, The pace of buybacks relative to cash generation and forecast attributable profit, Full-year attributable-profit delivery versus the ¥340.0bn forecast.
Regarding relative positioning, Bridgestone combines good annualized ROE, a 12.1% operating margin within the good benchmark range, strong cash conversion from earnings, and conservative capitalization. Its relative weakness is manufacturing working-capital efficiency: DSO, DIO, and the cash-conversion cycle are above warning levels, making inventory and collections the main determinants of whether the first-half margin recovery translates into durable free cash flow.
