History

Figures converted from Chinese renminbi at historical, period-end FX rates — see data/company.json.fx_rates for the run's rate table; renminbi-to-dollar rates are taken from the same Frankfurter source for the year each figure applies to. Amounts the filings themselves state in US dollars are unchanged, and dividends per share, which are declared in Hong Kong dollars, are shown as declared. Ratios, margins, multiples, unit volumes, share counts and dates are unitless or unchanged.

The record and its breaks

Prinx Chengshan dates itself to the Rongcheng Rubber Factory of 1976, and the FY2025 chairman's statement treats 2026 as the group's fiftieth year [1]. The corporate entity is much younger: the Cayman holding company was incorporated on 22 May 2015, and the shares have traded on the Main Board of the Hong Kong Stock Exchange since 9 October 2018 [2].

Four breaks organise everything after that. The first is the 2014–2015 buy-back of control from Cooper Tire and the pre-IPO restructuring that created the listed group. The second is the 2018 listing, which arrived in the same weeks as the first round of United States tariffs on Chinese tyres. The third is the Thailand production base, built between 2019 and 2022, which changed where the company manufactures, where it sells, and how much cash it consumed on the way. The fourth is the capital-allocation reset that began in FY2022, when the announced Anhui plant was suspended, and ended in 2025, when the group committed to a Malaysian base and a domestic off-the-road tyre plant instead.

This tab is a record, not an argument. Who controls and runs the company today sits in People; the named-rival and share record sits in Competition.

What the corpus does and does not cover. The primary record available here runs from the 2018 global offering prospectus through the FY2025 annual report signed on 30 March 2026, plus a news index to July 2026. The FY2018, FY2019 and FY2020 annual reports are not in the corpus, so the disclosed utilisation of the listing proceeds and the first two years of Thailand construction spending cannot be sourced to a filing page here. Only two earnings-call transcripts exist in the record — the FY2020 call of 31 March 2021 and the H1 2021 call of 31 August 2021 — and both are summarised on the Calls tab. Every period below is either accounted for or marked unavailable.

What the record produced

Revenue has risen in every year the corpus covers. Profit has not: FY2021 and FY2022 sit in a trough between the pre-Thailand years and the FY2023–FY2024 peak, and FY2025 gave back part of that peak.

Sources: the revenue and profit for the year rows of the FY2021 five-year summary, FY2017 to FY2021 [39]; the FY2025 five-year summary, FY2021 to FY2025 [40]; FY2016 revenue as reported in the 2018 global offering prospectus [41].

Gross margin traces the same shape more sharply. It fell from 22.3 per cent in FY2020 to 13.8 per cent in FY2021, recovered to 21.3 per cent in FY2023, and fell again to 18.1 per cent in FY2025.

Sources: the gross profit margin and net profit margin rows of the FY2021 Key Financial Indicators [42]; and of the FY2025 Key Financial Indicators [43].

Management said versus did

The record contains one quantified multi-year revenue target, a set of project-level capacity and timing commitments, a dividend policy, and an investment-return hurdle. The table below scores each against the outcome the filings later reported, and names the measurement basis where it matters.

Promise or target	Made	Basis	Measured at	Outcome
Annual dividend of no less than 20 per cent of distributable net profit attributable to equity shareholders	2018 prospectus [44]	Declared dividends over profit attributable	FY2021 to FY2025	Dividends declared every year. Converting declared per-share dividends at year-end rates and dividing by profit attributable, the payout was about 38, 29, 17, 30 and 26 per cent for FY2021 to FY2025; the FY2023 figure sits below the 20 per cent floor on that basis. The policy's own denominator, distributable net profit, is not disclosed as a flow — the reports disclose only a stock of distributable reserves, $312.6 million at end-2023 [45]
Invest only in projects with an internal rate of return of no less than 10 per cent and a payback period of no more than 10 years	2018 prospectus [46]	Project-level returns	FY2021 to FY2025	No project-level internal rate of return or realised payback has been disclosed in any annual report in the corpus. The only later payback figure on the record came on the August 2021 call, where the chief financial officer put Anhui phase I at about ten years — the outer edge of the stated hurdle
Expand all-steel radial capacity by 2.0 million units by 2021 in two phases costing about $72.2 million and $94.6 million, with paybacks of 2.5 and 3.5 years	2018 prospectus [47] [48]	Rongcheng all-steel capacity	FY2021 to FY2023	Shandong all-steel capacity reached 7.4 million units, against 4.7 million at the prospectus date [49] [50]. The capacity was delivered and exceeded, though under a differently structured programme; the 2.5 and 3.5 year paybacks were never reported against
Expand semi-steel radial capacity by 2.25 million units by 2021 at a cost of about $67.0 million, payback 4.8 years	2018 prospectus [51]	Rongcheng semi-steel capacity	FY2021 to FY2024	Shandong semi-steel capacity reached 11.2 million units by FY2023 and 11.53 million after the 2024 optimisation, against 6.5 million at the prospectus date [52] [53]. Delivered; payback never reported against
Group revenue of $2.52 billion in 2025, described as a stage goal of the medium and long-term plan	FY2021 chairman's statement [54]	Group revenue, FY2025	FY2025	Missed. FY2025 revenue was $1,686.5 million, about 74 per cent of the target [55]. The target appears once in the corpus and is not restated, revised or referenced in the FY2022 to FY2025 annual reports
Thailand phase II, 1.2 million all-steel and 4.0 million semi-steel units, to reach designed capacity in Q1 2022	FY2021 annual report [56]	Thailand capacity	Q1 2022	Met. Thailand stood at 2.0 million all-steel and 8.0 million semi-steel units at end-2022 [57]
Shandong expansion, 1.05 million all-steel and 2.8 million semi-steel units for about $101.9 million, to reach designed capacity in Q1 2022	FY2021 annual report [58]	Shandong capacity	Q1 2022	Met [59]
Anhui phase I, 800,000 all-steel and 5 million semi-steel units, about $472 million, funded by shareholder contributions and a syndicated loan	Board resolution 31 August 2021, FY2021 annual report [60]	Construction start and output	End-2022 target on the August 2021 call	Not delivered. The FY2022 report states the group decided to suspend implementation and that no definitive agreements had been entered into [61]. Anhui does not reappear in the investments or future-plans sections of the FY2023, FY2024 or FY2025 reports
Shandong semi-steel optimisation to 11.53 million units for about $16.9 million, and Thailand phase III of 2 million semi-steel units for about $28.3 million, both to reach designed capacity in H2 2024	Board resolutions 31 August 2023 [62]	Project completion	FY2024	Met. Shandong completed in Q2 2024 and Thailand phase III in Q4 2024 [63]
Malaysia base to commence in Q2 2025 with trial production in H2 2026, total investment $380 million	FY2024 annual report [64] [65]	Start date, cost, trial date	FY2025	Partly. Construction commenced in Q3 2025, not Q2; trial production is now expected in Q4 2026; and the stated total investment is now $299 million on the same capacity plan [66]
Off-the-road tyre project, construction from Q2 2025, designed capacity by 2029, output value about $137 million	FY2024 annual report [67]	Trial production	FY2025 and January 2026	Ahead of the disclosed path on the first milestone: trial production began in Q4 2025 and the first giant tyre rolled off the line on 19 January 2026 [68]

Two commitments made on the FY2020 call of 31 March 2021 can now be scored against the filings. The chief financial officer forecast double-digit group revenue growth for 2021; revenue rose 20.0 per cent to $1,186.5 million [69]. He also put FY2021 Thailand revenue at $283 million to $315 million; the FY2022 report's first segment disclosure shows overseas segment revenue of $285.1 million for FY2021, at the bottom of that range [70]. The undertaking that Thailand profit in 2021 would absorb its $7.6 million 2020 loss cannot be scored: no Thailand-level profit figure appears in the annual reports in this corpus.

Sources: FY2021 Annual Report, Chairman's Statement, for the $2.52 billion 2025 stage goal [71]; the FY2025 five-year summary, for the reported revenue outcome [72].

Capital allocation

Everything the group has built since listing has been built, not bought. The corpus records no acquisition, no disposal of a subsidiary, associate or joint venture, and no purchase, sale or redemption of listed securities in any year from FY2021 through FY2025 [73] [74]. Cash went to plants and to dividends.

Approved	Project	Stated cost	Stated objective	Disclosed outcome
2018 prospectus	Rongcheng all-steel expansion, two phases	$72.2 million and $94.6 million	Add 2.0 million units by 2021; paybacks 2.5 and 3.5 years	Capacity delivered; no payback or return reported [75]
2018 prospectus	Rongcheng semi-steel expansion	$67.0 million	Add 2.25 million units by 2021; payback 4.8 years	Capacity delivered; no payback or return reported [76]
H2 2020	Thailand phase II, all-steel	$82.8 million	1.2 million all-steel units per year	Designed capacity reached Q1 2022 [77]
H2 2020	Shandong expansion	$101.9 million	1.05 million all-steel and 2.8 million semi-steel units	Designed capacity reached Q1 2022 [78]
H1 2021	Thailand phase II, semi-steel	$141.0 million	4.0 million semi-steel units per year	Designed capacity reached Q1 2022 [79]
31 August 2021	Anhui phase I	About $472.3 million; 2022 budget of $275.2 million	800,000 all-steel and 5 million semi-steel units; second domestic base	Suspended in FY2022; no definitive agreements signed; not mentioned again [80] [81]
31 August 2023	Shandong semi-steel optimisation	$16.9 million	Raise semi-steel capacity to 11.53 million units	Completed Q2 2024 [82]
31 August 2023	Thailand phase III	$28.3 million	2 million semi-steel units per year	Completed Q4 2024 [83]
2025	Malaysia base, Kedah Rubber City	$380 million at disclosure, restated to $299 million	6 million semi-steel and 600,000 all-steel units; output value about $270 million at full capacity	Under construction; trial production expected Q4 2026 [84]
2025	Shandong off-the-road tyre project	$160.3 million in the chairman's statement, $152.1 million in the same year's management discussion	Fill the domestic high-end engineering tyre gap; output value about $137 million	Trial production Q4 2025; first giant tyre January 2026 [85] [86] [87]

The spending pattern that results is a three-year build, a three-year pause, and the start of a second build. Capital commitments outstanding at year-end tell the same story compressed: $9.9 million at end-2023, $10.7 million at end-2024, then $106.5 million at end-2025, which the report attributes to Malaysia and the off-the-road project [88].

Sources: capital expenditure from reported cash-flow statements; total dividend distribution per the management discussion in each year, FY2021 [89], FY2022 [90], FY2023 [91], FY2024 [92] and FY2025 [93].

Dividends are declared in Hong Kong dollars. The per-share record is flat for two years, then a step up, then a partial step back: an interim dividend appeared for the first time in FY2024 and did not recur in FY2025, so declared distributions per share fell from HK$0.65 to HK$0.50 even though the FY2025 statement presents the final dividend as sharing the fruits of development [94] [95].

Sources: the FY2024 interim dividend per ordinary share [96]; the FY2025 final dividend per ordinary share [97]; earlier years from the corresponding Report of the Directors. Dividends are declared in Hong Kong dollars and are shown as declared.

Where the growth came from

The FY2022 report introduced two reportable segments defined by operating location, domestic and overseas. On that basis the Thailand base went from 24 per cent of revenue in FY2021 to 38 per cent in FY2025, and in FY2022 and FY2024 it produced more gross profit than the far larger domestic segment.

Sources: the segment revenue rows of the FY2022 Segment Information note, for FY2021 and FY2022 [98]; FY2023 [99], FY2024 [100] and FY2025 [101] annual reports.

Sources: segment results as reported in the FY2022 [102], FY2023 [103], FY2024 [104] and FY2025 [105] annual reports.

Sales volume follows the capacity that was actually built. The group sold 18.61 million tyres in FY2021, 18.53 million in FY2022, then 25.03 million, 27.97 million and 29.29 million as Thailand phases II and III and the Shandong expansion came on stream.

Sources: total sales volume tables in the FY2021 [106], FY2022 [107], FY2023 [108], FY2024 [109] and FY2025 [110] annual reports.

Explanation drift

Four accounts changed materially over the period. Each is quoted at its stages, with the date and source.

Margin and cost pass-through, 2021. On the FY2020 call of 31 March 2021 the chief financial officer told analysts that over an annual cycle gross margin would stay at a stable level. On the H1 2021 call of 31 August he said that improving gross margin in the short term was very difficult, and described a price-transmission gap in the industry that remained under heavy pressure. The FY2021 annual report then reported gross margin of 13.8 per cent against 22.3 per cent in FY2020 [111]. Both call quotes and their context are on the Calls tab; the transcripts themselves are not filings in this corpus and carry no page link.

The second domestic plant. In FY2021 Anhui was presented as an approved investment with a registered subsidiary, a named local partner, a $472 million phase I and a $275.2 million budget line for 2022 [112]. In FY2022 the same section states that, based on forecasts of the economic situation and the company's capacity utilisation rate, the group decided to suspend the implementation of the project, and that no definitive agreements had been entered into [113]. From FY2023 the project is absent from the investments and future-plans sections altogether; the Anhui subsidiary remains in the group's subsidiary listings. No write-off, cost or recovery relating to the suspension is disclosed in the corpus.

The cost of the Malaysian base. The FY2024 chairman's statement and management discussion both put the total investment at approximately $380 million, with commencement in Q2 2025 and trial production in H2 2026 [114] [115]. The FY2025 report describes the same capacity plan, the same $270 million output value at full capacity, and a total investment of $299 million, with construction commenced in Q3 2025 and trial production expected in Q4 2026 [116]. No reason for the 21 per cent reduction is given.

The Thai shutdown. The FY2025 management discussion states that Prinx Thailand received a notice of temporary suspension of production from the Industrial Estate Authority of Thailand in August 2025 over the acceptance of waste treatment and emissions, that rectification was completed on 4 September and full resumption approved on 5 September, and that the matter had no material adverse effect on operations or financial position [117]. The chairman's statement covers the same episode as a compliance upgrade that ended in an environmental certification [118]. Contemporaneous trade coverage sized the affected plant at roughly 38 per cent of tyre revenue at the time of the order [119]. Thai all-steel utilisation fell from 87.1 per cent in FY2024 to 80.6 per cent in FY2025, and Thai semi-steel from 97.2 to 92.5 per cent [120]. No quantified revenue or profit impact from the shutdown is disclosed.

The scope of the non-competition undertaking. The prospectus describes the restricted business as tyre manufacturing and sale in the PRC and overseas [121]. Every annual report from FY2021 to FY2025 describes it as tyre manufacturing and tyre sales in the PRC [122] [123]. Over the same period the retained Malaysian business held by the controlling shareholder, and the call option and right of first refusal over it, stop being described in the annual reports, while the group builds its own Malaysian base at a different site [124] [125].

Definition and disclosure changes

Change	Before	After	Effect on comparability
Segment reporting	FY2021 note 5: one operating segment, manufacturing and selling of tyre products [126]	FY2022 note 5: two segments defined by operating location, domestic and overseas [127]	FY2021 is restated on the new basis inside the FY2022 report, so the series begins in FY2021 and not earlier
Ratio label in the Financial Highlights	FY2021 and FY2022 report a Gearing ratio of 56.9 and 55.4 per cent [128]	From FY2023 the identical row is labelled Asset to liability ratio, with the same historical values [129]	Values are unchanged; the label change matters because the management discussion separately reports a different gearing ratio, defined as net debt over total capital, which was minus 5.7 per cent in FY2025 [130]
Off-the-road project cost	FY2024 chairman's statement: approximately $160.3 million [131]	FY2024 management discussion and FY2025 report: $152.1 million [132] [133]	Two figures for the same project inside one annual report; neither is reconciled
Off-the-road unit capacity	FY2024: 840 thousand high-performance engineering radial tyres per year [134]	FY2025: 84 thousand per year, with the same 10 thousand giant tyres, the same 50 thousand tonnes and the same $137 million output value [135]	A tenfold restatement of the unit figure with no note; the tonnage and output-value anchors did not move
Malaysia project cost	FY2024: $380 million [136]	FY2025: $299 million on identical capacity and output-value assumptions [137]	Project economics stated at approval cannot be tracked against a stable cost base
Dividend cadence	FY2021 to FY2023: final dividend only	FY2024 adds an interim dividend of HK$0.15; FY2025 declares a final dividend only [138] [139]	Year-on-year dividend comparisons need the interim added back; the reported cash distribution in a calendar year also lags the fiscal year it relates to

The trade-measure record

Trade actions are external events, but they set the timing of the group's two largest capital decisions: Thailand after 2018, and Malaysia after 2024. The dated record is unusually specific.

Date	Measure	Rate applying to the group
24 September 2018	United States additional tariff on Chinese imports, covering all tyres exported to the United States in the track record period	10 per cent, raised to 25 per cent on 10 May 2019 [140] [141]
15 February 2019	United States anti-dumping and countervailing order, Chinese truck and bus tyres	Combined deposit rate 42.16 per cent [142]
23 December 2021	First administrative review, countervailing duty, Chinese truck and bus tyres	Shandong company deposits at 17.47 per cent [143]
19 July 2021	United States anti-dumping order, Thai passenger and light-truck tyres	Average 17.06 per cent [144]
January 2024	First administrative review of that order	Average 4.52 per cent [145]
10 October 2024	United States anti-dumping final determination, Thai truck and bus tyres	12.33 per cent [146]
6 May 2025	Second administrative review, Thai passenger and light-truck tyres	5.08 per cent [147]
20 September 2024	South Africa anti-circumvention investigation covering exports via Cambodia, Thailand and Vietnam	Preliminary 6.61 per cent; still under review [148]
21 May 2025 and 6 November 2025	European Union anti-dumping then countervailing investigations into Chinese passenger and light-truck tyres, with import registration from 22 January 2026 permitting retroactive duty	Not yet determined [149]

The rival record against which these rates should be read sits in Competition.

Leadership and governance events, dated

The people who hold these roles now, and their incentives, belong to People. What the record shows is the sequence.

Date	Event
5 March 2018	Che Hongzhi, the founder, re-designated as a non-executive director and appointed chairman [150]
January 2021	Che Baozhen ceases to serve as general manager of the Shandong operating company, remaining chief executive of the group [151]
November 2022	Jiang Xizhou, hired from Giti Tire in 2019, becomes executive vice president [152]
June 2023	Shi Futao ceases to serve as chief financial officer, remaining an executive director [153]
28 March 2024	Jiang Xizhou appointed a director; Cao Xueyu resigns as a director and continues as company secretary [154]
30 December 2024	Jiang Xizhou becomes executive president [155]
December 2025	Thailand and Shandong general managers exchange posts [156]
March 2026	Leo Chan joins as an independent non-executive director; the audit and risk management committee is reconstituted as all non-executive [157]
1 August 2026	Che Baozhen steps down as chief executive; Jiang Xizhou becomes president [158]

Headcount over the same span moved from 6,450 at end-2021 to 6,834 at end-2025, a 6 per cent increase against a 57 per cent increase in revenue and a 57 per cent increase in tyres sold [159] [160].

Gaps in the record

Three absences are material enough to name rather than smooth over. First, the FY2018 to FY2020 annual reports are not in this corpus, so the disclosed application of the $106.1 million of listing proceeds, and the reported cost and first-year economics of Thailand phase I, cannot be sourced here. Second, no project in the corpus has a disclosed realised return, payback or internal rate of return, despite the prospectus setting an explicit 10 per cent and ten-year hurdle. Third, the earnings-call record stops in August 2021; there is no transcript covering the Anhui suspension, the Thai shutdown, the Malaysia cost restatement or the FY2025 profit decline, so management's contemporaneous explanation of each rests on the annual reports alone.
