Business

What the company sells

Bottom line. Prinx Chengshan sold 29.3 million tyres in FY2025 for ¥11,806.8 million and kept ¥1,087.6 million of profit — about ¥37 per tyre [1]. Operating costs below the gross line are close to fixed at 8.6% of revenue, so nearly the whole earnings swing since FY2021 came from gross margin. Two plants, a distributor network the company does not own, and a third build cycle now starting define the rest.

The company began as a Shandong rubber factory in 1976 and now designs, manufactures and sells tyres from two production bases — Rongcheng in Shandong and Chon Buri in Thailand — with a third under construction in Kedah, Malaysia, two research and development centres in China, and sales centres in China, North America and Europe [2]. Product reaches over 160 countries [3]. Roughly 6,800 people run it [4]. The product taxonomy and the arena it competes in are set out in Industry; this chapter is about the mechanics of the money.

The revenue line divides into three products, and the division matters more than its size suggests. All-steel radial tyres — truck and bus fitments — were 8.4 million of the 29.3 million sets sold, but ¥6,664.2 million of the ¥11,806.8 million of revenue. Semi-steel radials for passenger cars were 20.4 million sets and ¥4,936.1 million. Bias tyres were 0.5 million sets and ¥201.4 million [7] [8].

Source: sales volumes per the FY2025 operation review [9] against revenue by product type [10]. Shares derived.

Dividing revenue by volume gives an average realised price of about ¥793 per all-steel tyre against ¥242 per semi-steel tyre — a truck tyre carries roughly 3.3 times the revenue of a car tyre. (Volumes are disclosed rounded to 0.1 million sets, so these unit figures carry about a percentage point of rounding.) Just over a quarter of the units therefore produce more than half the revenue, so the top line is most sensitive to the mix between them: at those realised prices, moving one percentage point of the 29.3 million sets from semi-steel to all-steel adds about ¥160 million of revenue, or 1.4% of the FY2025 total. Management describes FY2025 growth in both products as volume and price together: all-steel revenue rose 6.3% on a 5.3% volume gain and a slight price rise, semi-steel 9.8% on a 4.9% volume gain and a 4.7% price rise [11].

Per tyre sold, gross profit has ranged from ¥55.9 to ¥84.9 across the five years to FY2025, and profit for the year from ¥14.9 to ¥46.9.

Source: derived — gross profit and profit for the year from the five-year summary [12], divided by sales volume as disclosed for each year [13] [14] [15] [16] [17].

Between FY2021 and FY2024 the company more than tripled what it kept on each tyre, from ¥14.9 to ¥46.9, while volume grew 51%. FY2025 gave back a fifth of that level, to ¥37.1, even as volume rose again. Volume and unit profit have moved on different clocks, and the second one is not under management's control in the way the first is.

Channels and payment terms

The buyer of 83.7% of FY2025 revenue was a distributor, not a driver and not a carmaker. International distributors took ¥7,796.6 million, domestic distributors ¥2,078.9 million, and direct sales to automobile manufacturers ¥1,926.3 million [18].

Sources: sales-by-channel tables in the FY2022 [19], FY2023 [20], FY2024 [21] and FY2025 [22] annual reports. FY2021 is stated on the FY2022 report's restated basis, which folds private-label revenue into international distributors. Small raw-material trading revenue is excluded.

Four years of growth came from one place. International distributor revenue rose 82% between FY2021 and FY2025; domestic distributor revenue ended the period at ¥2,078.9 million against ¥2,043.0 million four years earlier, having fallen in three of those years. The direct-to-manufacturer channel is the volatile one — ¥1,209.2 million, then ¥619.1 million, then a climb to ¥1,926.3 million in FY2025, a 73.9% jump on a 57.6% rise in OE volume [23].

Management is explicit that the two moved together by design: it "tilted its production capacity to focus on ensuring the development of its export and OE businesses, which in turn led to a corresponding decrease in the sales of commercial vehicle tire replacement" [24]. That is a choice with a cash consequence, developed below.

No single customer is large. The top five accounted for 13.4% of FY2025 revenue and the largest for 3.7% [25]. Neither is any single supplier: the top five were 18.5% of purchases. This cuts both ways. No counterparty can dictate terms, and no counterparty is contractually obliged to keep buying — the switching terms behind that are set out in Competition.

What the company owns instead of customers is a network it organises but does not consolidate: 126 domestic distributors, 25,389 registered retail stores, and 8,078 stores on the "lighthouse e-station" ordering platform, of which 770 are top-tier accounts [26]. None of it sits on the balance sheet. The commitment that does is a four-year product warranty, carried as a ¥40.7 million charge in FY2025 [27] [28] — about a third of a percent of revenue.

At the 2018 listing the company granted customers a credit period of no more than two months, and receivable turnover ran 66 to 82 days [29]. That is the working-capital shape the distributor model was built on, and FY2025 is the year it stretched.

Where the tyres are made, and what that does to the margin

The company reports two segments, and they are defined by where production happens, not by where the customer is: a Domestic segment (Shandong) and an Overseas segment (Thailand) [30]. Shandong produced about 62% of FY2025 revenue and Thailand about 38% [31].

Delivery destination is a separate cut and looks nothing like the production split: China took ¥3,997.2 million of FY2025 revenue, the Americas ¥3,901.9 million, Asia excluding China ¥1,126.6 million, Africa ¥1,007.3 million, the Middle East ¥787.8 million and other countries ¥986.1 million [32]. Because anti-dumping and countervailing duties are assigned by country of production rather than country of sale, the segment split — not the destination split — is what trade measures price.

That is visible in the plants' own utilisation. Design capacity is 7.4 million all-steel and 11.53 million semi-steel sets a year in Shandong, and 2 million all-steel and 10 million semi-steel sets in Thailand. In FY2025 Shandong ran its all-steel lines at 93.8% against 82.6% a year earlier, while Thailand's all-steel utilisation fell to 80.6% from 87.1% [33]. The US anti-dumping duty on truck and bus tyres from Thailand, set at 12.33% for the group in October 2024, is the obvious candidate for that divergence [34].

Source: derived from segment revenue and segment results in the FY2022 [35], FY2023 [36], FY2024 [37] and FY2025 [38] annual reports. Segment results are stated before selling, administrative and research and development expenses, which the company does not allocate by segment.

Thailand's margin advantage was one percentage point in FY2021, widened to 11.7 points by FY2024, and halved to 6.0 points in FY2025. The dated record of how that base was built sits in History; what matters for the economics is that a plant carrying 38% of revenue delivered 46.2% of group gross profit in FY2025, down from 50.6% in FY2024.

Sources: segment revenue and results for FY2025 and FY2024 [39] [40]; non-current assets by location [41]. Margins derived.

The asset side is the asymmetry worth holding on to. Excluding deferred tax and associates, ¥2,965.7 million of non-current assets sit overseas against ¥2,440.4 million domestically — 54.9% of the fixed base in the plant that generates 38% of revenue [42]. Shandong turns ¥2.98 of revenue per ¥1 of non-current assets; Thailand turns ¥1.53. Thailand is the higher-margin, more capital-hungry and more tariff-exposed half of the company, and its margin premium is the variable that has moved most.

The cost structure and where the leverage sits

Below the revenue line the company is unusually simple. Raw materials and consumables were ¥8,400.2 million in FY2025 against ¥10,683.6 million of total costs across cost of sales, selling, administrative and research and development expenses — 78.6% of everything the company spends, and 71.1% of revenue on its own. Wages were ¥808.1 million and depreciation of property, plant and equipment ¥500.9 million [43]. The relationship between input prices and realised prices, and the lag between them, is the industry mechanic set out in Industry.

The three lines below gross profit have barely moved. Selling and distribution expenses were ¥522.2 million in FY2025 against ¥517.0 million in FY2024; administrative expenses ¥233.4 million against ¥236.0 million; research and development expenses ¥259.0 million against ¥250.7 million [44]. Together they came to ¥1,014.6 million, or 8.59% of revenue.

Sources: gross margin and operating margin per the five-year summary and key indicators [45] [46]; operating expenses are selling and distribution, administrative and research and development expenses as disclosed in each year's segment note [47] [48] [49], divided by revenue. Ratios derived.

Over FY2021 to FY2025 revenue grew 56.6% and those operating expenses grew 16.9%, falling from 11.51% of revenue to 8.59%. Gross profit grew 105.7% and operating profit — the line the accounts strike before finance items, and the measure the operating-margin series in the chart above divides by revenue — grew 341%, from ¥271.0 million to ¥1,194.4 million [50] [51]. Net finance costs of ¥0.2 million in FY2025 make that the same ¥1,194.4 million the accounts report as profit before income tax, the figure Valuation and Discount uses; it reconciles to profit for the year of ¥1,087.6 million at the 8.9% effective rate, and sits ¥21.7 million below the ¥1,216.1 million of EBIT used in Return on Capital. Operating margin rose 6.5 percentage points over that span. Gross margin contributed 4.3 points and the fall in operating expenses 2.9; the roughly 0.7-point difference is smaller other gains, which fell from ¥40.6 million in FY2021 to ¥19.7 million in FY2025.

That fixes the sensitivity. At FY2025 revenue, one percentage point of gross margin is ¥118.1 million — about a tenth of profit for the year after tax at the FY2025 effective rate of 8.9%. A 1% move in the raw-material bill is ¥84.0 million, or 7.0% of profit before income tax. Prices are set by distributors' willingness to pay and by duty schedules; costs are set by rubber, carbon black and steel cord markets. The company's own explanation for the FY2025 decline names both: "fluctuations in raw material prices and the impact of U.S. tariff policies" [52].

One qualification on the FY2025 fall. Trade-press reporting of the interim result puts first-half revenue at ¥5,705.2 million with attributable profit down 37.4% to ¥507.6 million [53]. Against full-year profit of ¥1,087.6 million, that implies roughly ¥580 million in the second half — above the ¥500 million implied for the second half of FY2024 on the same reporting, which put first-half FY2024 profit at ¥811.4 million [54] — and achieved despite a suspension that held the Thai plant to trial production from 8 August to 4 September 2025, with normal production resuming on 5 September [55]. No interim filing sits in this corpus, so the half-year split rests on secondary reporting and should be treated as indicative. On that basis the FY2025 decline reads as a first-half event rather than a full-year deterioration, which is the strongest single fact against reading FY2024 as a peak.

The balance sheet and the cash cycle

Property, plant and equipment of ¥5,056.7 million is 43.1% of ¥11,744.7 million of total assets [56]. Against it sits ¥7,189.5 million of equity, an asset-to-liability ratio of 38.8% and a return on equity of 15.8%, down from 21.9% [57]. The company ended FY2025 with ¥643.4 million of net cash on the run's shared measure; on its own definition, borrowings of ¥682.9 million [58] against ¥1,099.8 million of cash and restricted cash gave a gearing ratio of -5.7% [59] [60]. Either way, the debt burden is small.

The receivable line is where FY2025 shows strain. Trade and notes receivables rose ¥421.0 million to ¥2,441.6 million, and amounts due from related parties rose ¥351.5 million to ¥553.4 million [61]. Those two increases total ¥772.5 million against a revenue increase of ¥832.9 million. Days sales outstanding on trade and notes receivables went from 67.2 to 75.5; including related-party balances, from 73.9 to 92.6. Management attributes the trade movement to "the increased sales share to automobile manufacturers through direct sales channels, which have a longer accounts receivable collection period" [62] — the cash price of the channel tilt described above.

The ageing schedule sharpens it. Balances invoiced 4 to 6 months earlier rose from ¥3.1 million to ¥229.6 million, and the share of receivables under three months old fell from 99.5% to 89.2% [63]. That is a change of kind, not only degree, in a business that historically collected inside its two-month credit term.

The counterweight is inventory. Inventories fell ¥268.0 million to ¥1,674.9 million, taking inventory days from 82.0 to 63.2 [64] [65]. On the trade-only measure the cash conversion cycle therefore lengthened by about 2 days; counting the related-party receivable it lengthened by about 13. Cash generated from operations was ¥1,276.9 million and net operating cash flow ¥1,201.2 million, down 3.9% on a 17.1% fall in profit — the inventory release funded the receivable build [66]. That is a one-year source of cash, not a repeatable one.

Source: free cash flow and capital expenditure intensity per the run's shared financial series, derived from the consolidated cash flow statements; the FY2025 figures reconcile to purchases of property, plant, equipment and land use rights of ¥577.3 million against operating cash flow of ¥1,201.2 million [67].

Capital intensity tells the story of the last cycle and forecasts the next one. Capital expenditure ran at 18.6% of revenue in FY2021 during the Thai build-out, producing free cash flow of about -¥1,020 million, then fell to between 4.4% and 5.4% for four years while free cash flow ran ¥559 million to ¥660 million. FY2025 capex of ¥581.5 million was close to the ¥547.5 million of depreciation and amortisation charged — replacement-level spending.

That phase is ending. The Malaysian base at Kedah Rubber City is budgeted at US$299 million, commenced construction in the third quarter of 2025 and expects trial production in the fourth quarter of 2026 [68]. The Shandong off-the-road project is budgeted at ¥1.11 billion, with trial production begun in the fourth quarter of 2025 and design capacity targeted for 2029 [69]. Together that is roughly ¥3.2 billion at year-end 2025 exchange rates — about 45% of equity, and close to three years of FY2025 operating cash flow — against ¥643.4 million of net cash and a dividend distribution of ¥293.3 million in FY2025 [70]. The projects are staged over several years and internal cash flow plus modest borrowing can plausibly carry them, but the free cash flow of the last four years was earned in a capex trough that is closing.

What this report sets out to answer

Prinx Chengshan converts rubber into 29 million tyres a year across two countries and sells them mainly through distributors it does not own, keeping about ¥37 per tyre in FY2025. The costs it can control are small and already efficient; the spread it earns is set by input prices, by what distributors will pay, and increasingly by duty schedules assigned to the country a tyre is made in. The step-change from ¥14.9 to ¥46.9 of profit per tyre between FY2021 and FY2024 came almost entirely from that spread, and it came disproportionately from a Thai plant that now holds more than half the fixed asset base and saw its margin premium halve in a single year.

The question this report exists to answer: is the profit step-up of FY2023 and FY2024 a durable property of Prinx Chengshan's multi-country manufacturing model, or the high point of a cost-and-duty spread the company does not set — and one it is now committing roughly ¥3.2 billion of new capacity against.

The evidence points, on balance, toward durability being conditional rather than established: the fixed-cost leverage is real and permanent, but 46% of gross profit rests on a single offshore plant already carrying a 12.33% US truck-tyre duty, with an EU anti-dumping investigation open against Chinese-origin passenger tyres since May 2025 and import registration permitting retroactive duty from January 2026 [71]. The strongest fact against that caution is the second-half FY2025 recovery noted above. What would settle it is a full year at the FY2025 exit run-rate with the Thai plant at pre-duty utilisation, or a definitive EU determination that leaves the Shandong base's export economics intact.

For orientation, the market capitalisation on 3 August 2026 was HK$4.33 billion, at a closing price of HK$6.815 against FY2025 earnings of RMB1.71 per share — roughly 3.6 times trailing earnings at year-end exchange rates. The valuation question that number raises belongs to a later chapter; what this one establishes is the engine those earnings come out of.
