Toyoda Gosei

Where we land

Toyoda Gosei makes the seals, trim and safety equipment that go into cars, and sells them mainly to Toyota and the companies around it. Over four years its operating profit, what is left after the costs of making, selling and running the company, has climbed from 32.5bn to 87.8bn. Yet the shares sell for about 10 times earnings, a price that makes sense only if those profits are expected to shrink. We find that price hard to square with the record, and we award it gold.

The reasons for caution are real. This supplier leans on one dominant customer, works on thin margins and buys oil-based raw materials just as oil has become sharply dearer. Those risks deserve a discount. The question is how large, and today's price asks for a decline far deeper than anything the business has recently shown.

What the business is

Everything the company sells falls into a single line: vehicle parts. That means rubber seals around doors and windows, plastic interior and exterior parts, and safety systems such as airbags and steering wheels. Our figures do not split sales by customer, but Toyota and its group are the dominant buyer, and the business largely rises and falls with how many cars Toyota builds and how much of this content goes into each.

The economics are those of a volume supplier, not a premium brand. Of every sale, about 16% is left once the direct cost of making the product is paid, the gross margin; after running costs, about 7% remains as operating profit. Most of the money that comes in goes straight back out on materials and production.

What redeems a thin margin is steadiness. Over five years the gross margin has had a middle value of 15%, typically moving no more than 2 points either side. The company has held its share of each car's value through good years and bad, even if it has never commanded a fat one.

Why now

The force driving the business is Toyota's production. Toyota's global build rates decide most of Toyoda Gosei's orders, and hybrids and larger vehicles carry more of its content, so a mix tilted towards them lifts sales faster than raw vehicle numbers would.

Those who follow the company closely are moving their numbers up: in the past 45 days, five upgrades to profit forecasts against one cut. On how reliably it turns sales into profit and cash, it is among the strongest companies we rate.

Yet with profits at a record, the shares sit at about book value, meaning the market values the company at roughly what its own accounts say its net assets are worth, and at about 10 times earnings. It joined the Gold Income 10 this month.

The case for

The plainest argument is the profit record. Operating profit rose every year from 32.5bn in the twelve months to September 2022 to 87.8bn in the twelve months to September 2026, nearly tripling. Net profit, what is left for shareholders after interest and tax, followed the same path from 22.6bn to 61.2bn. This was a steady climb, not one lucky year.

Nor do analysts expect the climb to stop. Their consensus has earnings per share rising a further 9.3% next year, and with upgrades outnumbering cuts five to one, expectations are being revised towards the company, not away from it.

The shares have begun to reflect this, rising over the past three months strongly enough to rank near the top of the market for the strength of their run. That reads better as a recovery than a breakout, since the run is still slightly weaker than a year ago, but it suggests the market is starting to notice a business whose profits have outpaced its share price.

A company growing profits every year, with forecasts still rising and a valuation close to its own net assets, is being priced as though its best years are behind it, when the evidence points the other way.

Where the growth could come from

The clearest explanation for the recent surge is Toyota. Sales grew 13% last year against 6% a year over three years, well above trend. With no company announcements to point to, the pattern fits strong Toyota output and a mix rich in hybrids and larger vehicles rather than anything Toyoda Gosei did on its own. If Toyota keeps building at this rate, the expected rise in earnings has a sound footing; if it slows, that forecast could prove too optimistic.

The main threat to margins is oil. Brent crude stands at $123 a barrel, up 88% in a year, and plastics and synthetic rubber, the company's core raw materials, are made from it. Price talks with Toyota usually lag material costs, so dearer oil can eat into profit even while sales grow, undercutting the upward forecast revisions.

Within the existing business, safety systems offer a lever. Tighter safety rules and more airbags per car add value, and safety equipment carries more value per vehicle than many rubber parts. Selling airbags and steering wheels to carmakers outside the Toyota group would also make growth less dependent on one customer, though our figures do not break safety systems out from the single vehicle-parts line.

Further out sits an option on electrification. As cars move to batteries, demand for some traditional parts, fuel-system components among them, shrinks. The company is developing lightweight resin parts and battery-related components, and has know-how in gallium-nitride semiconductors, used in chips that manage electrical power. This is small next to the core business today; it would matter if it replaced lost revenue with higher-value products, signalled by disclosed orders for electric-vehicle components or a commercial customer for the chips.

Finally, there is a possible spur for the shares rather than sales. Across Japan, including within the Toyota group, companies face pressure to unwind cross-shareholdings and earn more on their capital. Selling such stakes, or returning more cash through dividends and buybacks, could raise the return on shareholders' money without changing how fast the operating business grows. An announced buyback, a higher dividend target or disclosed sales of cross-held shares would be the sign.

The case against

The market has reasons for the price. At 10 times earnings, about 1.0 times book value and 6.5 times operating profit, the shares rank close to the top of the whole market for cheapness and below most peers: DENSO trades on 11 times earnings, Bridgestone on 12 and Sumitomo Electric on 13. But cheapness among car-parts makers is not unusual. Niterra trades on just 7 times earnings with far higher margins, so a low multiple here is not by itself proof of a mistake.

Margins are the heart of the objection. The quality of the business ranks near the top of its peer group, a standing that has edged up over the year, ahead of DENSO, Aisin and Bridgestone and level with Niterra. Yet its 7.2% operating margin is only middling: it matches DENSO and beats Aisin's 4%, but trails Bridgestone's 12% and Niterra's 19%.

That thinness cuts both ways. With a gross margin of 16.5%, a small squeeze on costs or volumes takes a large share of profit, and the record shows it can happen: operating profit fell by a third in the year to September 2022. The one comfort is that net debt is roughly zero, so the balance sheet adds no strain of its own.

The growth rate also looks stretched. Last year's 12.9% sales growth is about double the three-year trend of 6.1%, and over the past twelve months the company's standing on growth has slipped to around the middle of the market. If sales drift back towards trend, as above-trend years often do for a supplier tied to one carmaker, profit gains may slow and the recent forecast upgrades could reverse.

What the price assumes

One way to read a share price is to ask what it requires. Suppose the price stays flat for five years and the shares then trade at 18.5 times earnings, the middle value for every profitable listed company we cover. For that to hold, earnings per share would need to shrink by 12% a year, to 53.18.

The company's own record points elsewhere. If the recent trend in operating profit simply continued, earnings per share would reach 136.70 in five years, 257% of what the price requires; the trend amounts to earnings growing about 6% a year. This is past results carried forward, not a forecast, and because earnings have risen in steps rather than compounding smoothly, the level comparison is the fairer test. On it, the gap is wide.

The market has begun to move, with the shares up 37% over the past year and 8% over six months. Even so, the price still assumes a sharp decline in profits rather than the steady progress the record shows.

The other side of the medal

The risk we would watch above all is a combination: a parts maker leaning on Toyota just as oil near $123 a barrel pushes up its resin and rubber costs. Either half alone would be manageable. Together they could turn record profits into the shrinking ones the price already assumes.

A supplier with many customers can push higher costs onto those willing to pay and walk away from those who will not. One whose main customer is Toyota has far less freedom, and talks with a buyer that size lag the moves in materials. With a margin this thin, even a modest delay in recovering higher costs could take a sizeable bite out of profit, and if Toyota's output eased at the same time, volume would no longer cover the gap. It would show first as an operating margin slipping while sales still grow, alongside falling Toyota production.

What to watch

First, oil alongside the margin. If the operating margin, now 7%, holds as oil costs bite, or the company says Toyota and other carmakers have agreed to pay more for pricier materials, the main threat to profit will have been contained. Brent moves daily, well before results appear, so a sustained rise or retreat gives early warning of the pressure coming through.

Second, Toyota's monthly global production and sales, the closest thing to a running read on Toyoda Gosei's sales. Output at or above last year's level, with the company's sales keeping pace, would support the expected rise in earnings; a falling trend would warn that the above-trend growth is fading.

Third, a wider customer base: announced airbag or steering-wheel orders from carmakers outside the Toyota group, or a rising share of sales to them. Each would loosen the dependence on a single buyer that sits at the root of the main risk.

Finally, the warning sign that would undo the case. Operating profit falling back as it did in the year to September 2022, when it dropped to 32.5bn from 48.9bn, or gross margin slipping below its steady 15% band, would show the earnings recovery is cyclical rather than durable. Until then, the record argues against the decline the price assumes.
