1. Executive Summary

Suchangchai A mainly produces small- and medium-power off-road diesel engines. In 2025, the company generated operating revenue of RMB 2.476 billion, up 2.50% year on year; in the first half of 2026, revenue was RMB 1.670 billion, up 6.96% year on year, attributable net profit was RMB 105 million, up 43.09%, and attributable net profit excluding non-recurring items was RMB 85.248 million, up 51.42%. However, net cash flow from operating activities was negative RMB 135 million in the first half of 2026. Profit growth was also supported by non-core factors, including the sale of certain shares, dividends from Bank of Jiangsu and cash-management income. The quality of cash conversion from the earnings improvement therefore still requires monitoring.

The company is highly dependent on its diesel-engine business. Diesel-engine revenue was RMB 2.284 billion in 2025, accounting for 92.25% of operating revenue, while the diesel-engine gross margin declined from 13.65% in 2024 to 11.91% in 2025. Raw-material costs accounted for 78.01% of the relevant operating costs of diesel and gasoline engines, while energy costs increased 22.37% year on year. This indicates that the company remains in a midstream manufacturing segment sensitive to upstream costs and with relatively strong downstream customer bargaining power; its ability to pass through costs remains unstable.

The company has the “Changchai” brand, accumulated expertise in single-cylinder and small- and medium-power products, domestic and overseas sales and after-sales networks, and synergies between casting and engine assembly. Gasoline engines, hybrid powertrains, hydrogen internal-combustion engines and high-horsepower diesel engines represent potential product-upgrade directions. However, hybrid and hydrogen internal-combustion engines remain at the R&D or product-reserve stage and cannot yet be regarded as sources of scaled revenue. Recently, a subsidiary subscribed RMB 50 million to participate in a RMB 1 billion industrial investment fund, targeting the new-energy vehicle, new-energy and next-generation information-technology value chains. As of now, no specific investee projects or returns have been disclosed.

As of September 11, 2026, the share price closed at RMB 5.19, corresponding to approximately 44x forward P/E, approximately 73–75x forward P/E excluding non-recurring items, and approximately 1x P/B. The share price was below the MA5 and MA10 and close to the MA20 and the Bollinger midline. RMB 5.14–5.20 was the short-term support zone, while RMB 5.28–5.40 was the resistance zone. Recent trading value and turnover were at low-to-medium levels, major capital flows were biased toward outflows in early September, and no sustained high-volume breakout structure had yet formed.

2. Company Overview

2.1 Basic Information

2.2 Principal Businesses and Product Positioning

• Diesel engines: Revenue was RMB 2.284 billion in 2025, accounting for 92.25% of operating revenue and increasing 1.82% year on year. Products cover single-cylinder and multi-cylinder engines with power ranging from 3kW to 180kW, mainly targeting small- and medium-power off-road applications.
• Gasoline engines: Mainly “Robin” brand products. Revenue was RMB 137 million in 2025, accounting for 5.52% of operating revenue and increasing 11.23% year on year. Products mainly support small power equipment, generator sets and related machinery.
• Supporting generator sets and other businesses: Other-business revenue was RMB 55 million in 2025, accounting for 2.23% of operating revenue.
• Downstream applications: Agricultural machinery, including tractors, combine harvesters, rotary tillers and crop-protection machinery; small construction machinery; generator sets; marine machinery; light commercial vehicles and other power equipment.
• R&D and product reserves: China IV off-road diesel engines, high-horsepower diesel engines, light-duty engines, diesel engines for generator sets, hybrid powertrains, hydrogen internal-combustion engines and low-emission, energy-efficient engines. Hybrid and hydrogen internal-combustion engines remain at the R&D or product-reserve stage and cannot be regarded as having generated scaled commercial revenue.

2.3 Position in the Upstream and Downstream Value Chains and Cost-Profit Structure

Suchangchai is positioned in the midstream powertrain segment of the agricultural-machinery, construction-machinery and generator-set value chains. Its core products are small- and medium-power off-road diesel engines, with gasoline engines as a supplement. The company has the Changchai brand, a broad product portfolio, channel networks and some in-house casting capabilities. Overall, however, it remains a fully competitive, cost-sensitive manufacturer with relatively low gross margins. It does not have the strong pricing power of an upstream resource company and does not benefit from the terminal whole-machine brand premium of a downstream manufacturer.

• Major inputs include cast-iron and cast-aluminum materials, steel and forgings, and core engine components such as crankshafts, cylinder blocks, cylinder heads, pistons and connecting rods, as well as fuel-injection systems, turbochargers, sensors, electronic-control systems, rubber parts, seals, electrical components, energy, electricity and processing services.
• In 2025, raw-material costs were RMB 1.661 billion, accounting for 78.01% of the relevant operating costs of diesel and gasoline engines; labor costs accounted for 11.10%, depreciation for 2.75% and energy for 1.45%. Raw materials were the most important cost variable.
• Purchases from the five largest suppliers amounted to RMB 334 million in 2025, accounting for 18.31% of annual total purchases, with no related-party purchases. Overall supplier concentration is not high, but the company remains a price taker for upstream costs such as steel, castings, parts and electronic components and has not demonstrated clear bargaining power over suppliers.
• The company has in-house casting and processing plants that provide internal support for certain diesel-engine components. The casting and internal-combustion-engine assembly businesses have production and quality synergies, which can reduce external purchases and process transfers, shorten delivery cycles and strengthen component quality control. The annual report did not disclose casting capacity, the internal-support rate or the proportion of self-manufactured components; it is therefore not possible to conclude that the company has formed a fully integrated value-chain loop.
• The annual report did not disclose detailed purchase amounts for steel, aluminum, castings or electronic-control systems, so the cost shares of individual raw-material categories cannot be accurately broken down further.
• Downstream customers include tractor and combine-harvester manufacturers, construction-machinery OEMs, generator-set manufacturers, marine-engine manufacturers, individual distribution markets and overseas distributors.
• The company uses a combination of direct sales and distribution. Direct sales are mainly used for OEMs, while distributors are mainly used in individual circulation markets oriented toward farmers and in overseas markets. Direct-sales revenue was RMB 1.274 billion in 2025, accounting for 51.43% of operating revenue; distribution revenue was RMB 1.203 billion, accounting for 48.57%. Distribution revenue increased 25.04% year on year, while direct-sales revenue declined 12.41%.
• Sales to the five largest customers amounted to RMB 1.099 billion in 2025, accounting for 44.40% of annual total sales; the largest customer accounted for 25.58%. These figures are for 2025, and customers were disclosed anonymously, so the identities of individual customers and the stability of concentration cannot be determined.
• In direct sales to OEMs, customers generally have strong purchasing bargaining power regarding emissions, reliability, delivery and price. In distribution and overseas markets, the company benefits from the Changchai brand, product compatibility and after-sales networks, but faces channel-discount, inventory and foreign-exchange risks.
• Agricultural-machinery demand is affected by agricultural-machinery purchase subsidies, replacement and renewal policies, grain prices, weather and farmers’ operating returns. Demand for construction machinery and generator sets is related to infrastructure, industrial investment, exports and equipment-renewal cycles.
• As of December 31, 2025, the book balance of accounts receivable was RMB 595 million, and the carrying value after deducting provisions for bad debts was RMB 452 million. Operating revenue in 2025 was RMB 2.476 billion. Based on the book balance, accounts receivable were equivalent to approximately 24.0% of full-year operating revenue; based on carrying value, the ratio was approximately 18.3%. Accounts receivable aged more than three years amounted to RMB 135 million, including RMB 130 million aged more than five years; the company had recognized RMB 144 million in provisions for bad debts. The combined balance of receivables from the five largest customers was RMB 361 million, accounting for 60.63% of the accounts-receivable balance, while the largest customer accounted for RMB 269 million, or 45.10%. These data indicate a relatively large amount of long-outstanding receivables and dependence on collections from core customers. The evidence on working-capital bargaining power is more consistent with the characteristics of a midstream manufacturer facing upstream cost pressure and downstream customer bargaining power.
• The top five suppliers accounted for 18.31% of purchases in 2025, while the top five customers accounted for 44.40% of sales and the largest customer accounted for 25.58%. Customer concentration was clearly higher than supplier concentration. Both customers and suppliers were disclosed anonymously. The relevant concentration data cover only 2025, and the research materials did not provide data for other years for comparison; the latest annual report should prevail. The company did not disclose the specific names of individual suppliers or customers or the stability of long-term cooperation.

The company is positioned in the midstream powertrain segment of the agricultural-machinery and off-road-power value chains. It is a cost-sensitive, fully competitive manufacturer focused on small- and medium-power diesel engines, rather than a high-margin upstream resource company or a high-margin downstream terminal brand. Future gross-margin improvement will depend mainly on the volume ramp-up of high-horsepower and higher-value-added products, product-mix upgrades, procurement cost reductions, casting synergies, economies of scale and improved overseas-channel profitability. The decline in gross margin in 2025 indicates that the company has not yet established stable cost pass-through capabilities.

3. Financial Data and Valuation Analysis

3.1 Recent Operating Performance

Attributable net profit excluding non-recurring items was RMB 85.248 million in the first half of 2026, up 51.42% year on year; full-year 2025 attributable net profit excluding non-recurring items was RMB 20.574 million, down 61.15% year on year. Basic EPS was RMB 0.1489 in the first half of 2026, weighted-average ROE was 3.00%, comprehensive gross margin was 14.87% and net margin was approximately 6.58%.

Revenue grew moderately in the first half of 2026, while attributable net profit and attributable net profit excluding non-recurring items grew significantly faster than revenue. Gross margin increased 2.08 percentage points from the same period a year earlier, indicating a clearer improvement in core profitability than in 2025. Profit growth was also supported by non-core factors such as the sale of certain shares, dividends from Bank of Jiangsu and cash-management income. Net cash flow from operating activities was negative RMB 134.71 million, further deteriorating from negative RMB 74.306 million in the same period a year earlier, requiring attention to the quality of earnings conversion. Although attributable net profit increased sharply in 2025, attributable net profit excluding non-recurring items declined year on year, indicating that non-recurring gains made a substantial contribution to profit growth that year.

3.2 Earnings Forecast

As of September 13, 2026, no valid, cross-verifiable multi-institution consensus earnings forecasts for 2026–2028 covering Suchangchai A had been identified. Relevant pages on Tonghuashun and East Money did not display clear institutional forecasts for net profit, EPS or consensus target prices. Forecast information encountered during the research process that was inconsistent with the company’s business and scale was excluded and was not used as a forecast basis for 000570.

3.3 Valuation and Institutional Ratings

As of intraday trading on September 11, 2026, the latest intraday price was approximately RMB 5.15, total shares outstanding were approximately 706 million, total market capitalization was approximately RMB 3.64 billion, forward P/E was approximately 44.07x, forward P/E excluding non-recurring items was approximately 73.38x and P/B was approximately 1.00x. Another market-data source showed an intraday price of approximately RMB 5.23, forward P/E of approximately 44.76x, P/E excluding non-recurring items of approximately 74.52x and P/B of approximately 1.02x. The differences mainly reflect the market-data timestamp, valuation basis and data-refresh timing. Overall, an unadjusted P/E of approximately 44x is not low for a traditional internal-combustion-engine and agricultural-machinery power company. An adjusted P/E of approximately 73–75x indicates that recurring core earnings remain relatively low. P/B of approximately 1x mainly reflects the relatively large net-asset base and low profitability and ROE; it does not indicate high earnings quality. ROE was 3.00% in the first half of 2026, operating cash flow was negative and investment income continued to contribute to profit. Although attributable net profit excluding non-recurring items increased 51.42% year on year, if profit growth cannot be sustained, the current P/E valuation will face some pressure.

4. Recent News and Announcements

4.1 No New Major Announcements Retrieved for September as of September 13, 2026

As of September 13, 2026, no new major announcements, earnings forecasts, share repurchase announcements, changes in holdings by the controlling shareholder, major mergers and acquisitions or regulatory penalty announcements disclosed by Changchai in September 2026 had been identified. The latest announcement that could be cross-verified in the public disclosure record was the “Announcement on the Progress of the Subsidiary’s Participation in the Establishment of an Equity Investment Fund and Related-Party Transaction,” disclosed on August 26, 2026. This conclusion is based on the announcement lists of the Shenzhen Stock Exchange and public announcement databases and does not mean that information not retrieved absolutely does not exist. Subsequent information should be based on disclosures from the Shenzhen Stock Exchange and CNINFO.

4.2 Subsidiary Completed Private-Fund Registration for Participation in an Industrial Investment Fund

On August 26, 2026, the company disclosed that “Yuanzhi Changtou Xingyu (Changzhou) Equity Investment Partnership (Limited Partnership),” in which wholly owned subsidiary Changzhou Housheng Investment Co., Ltd. participated, had completed private investment fund registration with the Asset Management Association of China. The fund registration code is SBWE85, the registration date was August 24, 2026, the manager is Shenzhen Yuanzhi Venture Capital Co., Ltd. and the custodian is Industrial and Commercial Bank of China Limited. Changchai had originally planned to invest RMB 50 million through Housheng Investment in the establishment of the fund. The fund’s initial investment focus was mainly new-energy vehicles and the new-energy value chain, including equipment, materials and components. This matter represents subsequent progress in the establishment of an investment and related-party transaction and is not a direct acquisition by the listed company of operating assets. The announcement did not disclose any new change in the listed company’s cash contribution. The company will continue to fulfill its disclosure obligations based on the fund’s subsequent progress.

4.3 Industrial Investment Fund Changed Its General Partner and Expanded Its Investment Scope

On August 14, 2026, the company disclosed adjustments to the general partners and investment scope of the Yuanzhi Changtou Xingyu Fund. The original general partners, Changzhou Xinhui Private Fund Management Co., Ltd. and Changzhou Xingyu Industrial Investment Co., Ltd., withdrew from the partnership. Changzhou Xingyu Xinhui Venture Capital Co., Ltd. was added as a new general partner and executive partner. The fund was converted to a dual-GP structure, with Shenzhen Yuanzhi Venture Capital Co., Ltd. as the other GP. The investment scope was expanded from the upstream and downstream value chains of new-energy vehicles and new energy to include the upstream and downstream value chains of the “next-generation information-technology supporting industries.” The fund’s total subscribed capital is RMB 1 billion, of which Changzhou Housheng Investment Co., Ltd. subscribed RMB 50 million, representing 5%. The change does not involve any change in Changchai’s capital contribution. The company stated that it would not have a material impact on normal production and operations or financial condition and would not create new related-party transactions. No specific investment projects, project returns or direct contribution to the company’s profit have been disclosed.

4.4 First-Half 2026 Report Shows Profit Growth, but Operating Cash Flow Was Negative and Impairment Was Recognized

On August 21, 2026, the company disclosed its first-half 2026 report and related announcements. Operating revenue was RMB 1.670 billion in the first half of 2026, up 6.96% year on year; net profit attributable to shareholders of the listed company was RMB 105 million, up 43.09%; net profit excluding non-recurring items was RMB 85.2479 million, up 51.42%; and net cash flow from operating activities was negative RMB 135 million, with the negative amount further expanding from the same period a year earlier. The company will not pay an interim cash dividend, issue bonus shares or convert capital reserves into share capital. During the same period, the company recognized or reversed impairment provisions for accounts receivable, other receivables, inventories and fixed assets as of the end of June 2026, ultimately recognizing an impairment loss of RMB 18.0616 million. Future attention should focus on accounts-receivable collections, inventory turnover and improvement in operating cash flow.

4.5 No New Earnings Forecast or Results Announcement Retrieved as of September 13

As of September 13, 2026, no new earnings forecast, results announcement or earnings warning for the third quarter or full year of 2026 had been identified. The latest clearly disclosed earnings forecast was the first-quarter 2026 earnings forecast released on April 15, 2026, in which the company expected first-quarter attributable net profit to increase 60.11%–82.98% year on year. The subsequently disclosed first-quarter report showed attributable net profit of RMB 74.3949 million, up 70.16% year on year. The results were partially validated by the first-half report, but this was not a new announcement in September 2026.

4.6 No Recent Share Repurchase or Share-Change Announcement Retrieved as of September 13

As of September 13, 2026, no recent disclosure by 000570 of a share-repurchase plan, repurchase-progress announcement or repurchase cancellation announcement had been identified. Among the 2026 announcements retrieved, recent matters mainly concerned the industrial investment fund, the first-half report, impairment provisions and housing expropriation compensation. No titles containing “share repurchase,” “repurchase progress” or “repurchase cancellation” appeared. This conclusion only means that no relevant information was retrieved from public announcements and cannot be used to absolutely infer that the company has no undisclosed or not-yet-disclosable share arrangements.

4.7 Shareholder Count Rebounded Slightly by the End of July 2026

Investor-interaction information from the company showed that the total number of A- and B-share shareholders was 45,663 as of June 18, 2026; the total number of ordinary shareholders disclosed in the interim report was 45,319 as of June 30, 2026; and the total number of A- and B-share shareholders was 45,971 as of July 31, 2026, an increase of 652 households, or approximately 1.44%, from June 30. The shareholder count declined noticeably from May to June 2026 before rebounding slightly in July. These data came from the company’s investor-interaction responses and public F10 materials. They are not share-increase or share-reduction announcements and cannot be directly equated with capital inflows from any specific shareholder.

4.8 Changes in Institutional Holdings Among the Top 10 Tradable Shareholders

The interim report as of June 30, 2026 showed that Changzhou Investment Group Co., Ltd. remained the largest shareholder, with a 32.26% stake and 227,663,417 shares. Institutional investors including the Huashang Lexiang Internet Flexible Allocation Mixed Securities Investment Fund and the Broad Wisdom Jiuhang Mixed Securities Investment Fund appeared among the top 10 tradable shareholders. UBS AG held approximately 2.1622 million shares, representing approximately 0.31%, a decrease from the previous reporting period. Media reports also mentioned that Barclays Bank and other institutions had exited the top 10 tradable shareholders, but this reflects media compilations of interim-report shareholder data; the company’s original interim-report tables should prevail. These changes relate to the shareholder structure as of June 30, 2026 and do not represent real-time holdings changes in September 2026.

4.9 No Recent Changes in Holdings or Pledge Announcements by the Controlling Shareholder or Directors and Senior Executives

As of September 13, 2026, no recent announcements of new increases, reductions, pledges or releases of pledges involving Changzhou Investment Group Co., Ltd. or the company’s directors and senior executives had been identified.

4.10 Industrial Investment Fund Positioning Does Not Constitute a Completed Major Acquisition

No major asset acquisition, issuance of shares for asset purchases or major asset restructuring by the company was identified recently. The matter most relevant to acquisitions and investment is currently the Yuanzhi Changtou Xingyu industrial investment fund. Changchai subscribed RMB 50 million through Housheng Investment, while the fund’s total subscribed capital is RMB 1 billion. Its principal investment areas are the new-energy vehicle, new-energy and next-generation information-technology supporting value chains. As of August 26, 2026, the fund had only disclosed completion of private-fund registration and had not disclosed specific investee projects or investment returns. Accordingly, this matter should be defined as industrial investment fund positioning and progress on a related-party transaction, rather than a major acquisition completed by the listed company.

4.11 Housing Expropriation Compensation for the Sanjing Branch Remains in Progress

The company’s interim report disclosed that housing expropriation compensation for the Sanjing branch on state-owned land remains in progress. As of the end of the first-half reporting period of 2026, the company had cumulatively received the first compensation payment of RMB 30 million. The company and relevant government departments had reached agreement on land consolidation, standards enhancement and subsequent compensation payments and planned to sign a supplemental agreement. The matter was approved at the company’s first extraordinary general meeting of 2026 held on July 21, 2026. The company also disclosed that the housing expropriation compensation agreement for the casting plant involved total compensation of RMB 346.8569 million, but a formal expropriation compensation agreement had not yet been signed as of the interim-report disclosure date. This matter may affect future cash flow, asset-disposal gains and production layout. However, it is inappropriate to recognize the full compensation amount or gains in advance. Actual gain recognition depends on the signing of the compensation agreement, payment of funds and accounting-recognition progress.

4.12 Extension of the Board Election

On June 10, 2026, the company disclosed a reminder announcement regarding the postponement of the board election. This was not a new development in September 2026, but it remains a recent corporate-governance matter. Future attention should focus on the election arrangements and any changes in the management and governance structure.

4.13 Overall Assessment of Recent Announcements

As of September 13, 2026, the main themes of 000570’s recent announcements included the completion of private-fund registration and expansion of the investment scope of the industrial investment fund. Through the related industrial fund, Changchai is positioning itself in the new-energy vehicle, new-energy and next-generation information-technology value chains, but no specific project implementation has been disclosed and the short-term earnings contribution remains uncertain. Operating revenue increased 6.96% in the first half of 2026, attributable net profit increased 43.09% and net profit excluding non-recurring items increased 51.42%, but operating cash flow was negative and an impairment loss of RMB 18.0616 million was recognized, requiring attention to earnings quality and cash collections. No new repurchase, controlling-shareholder purchase, major reduction, major acquisition or regulatory penalty announcement was identified recently. Shareholder-count and top-shareholder data are mainly as of July 31 or June 30, 2026 and do not represent the real-time shareholder structure in September. Housing expropriation compensation amounts are contractual or proposed arrangements; the timing and amount of actual gain recognition remain dependent on the formal agreement, payment of funds and accounting treatment.

5. Share-Price Performance and Technical Analysis

5.1 Price Overview

5.2 Technical Indicators

As of the September 11, 2026 close, Suchangchai A had declined consecutively from the September 9 interim high of RMB 5.37 to RMB 5.19, falling below the MA5 and MA10 while remaining close to the MA20 and the Bollinger midline at approximately RMB 5.18. RMB 5.14–5.20 was the first defense zone formed by the overlap of recent lows, the MA20 and the Bollinger midline. RMB 5.28–5.40 was the resistance zone formed by the MA5, MA10, recent high and Bollinger upper band. RSI was approximately 62 and had not entered clear oversold territory. Recent trading value and turnover were at low-to-medium levels, and verifiable major-capital-flow data in early September showed a bias toward outflows, indicating only moderate short-term buying support. Shareholder data as of June 30, 2026 showed relatively high institutional ownership, but the quarterly lag means that the data cannot directly represent current third-quarter capital activity.

5.3 Short-Term Outlook (Next Week, Scenario Analysis for Reference Only)

⚠️ Risk warning: The following is only a subjective scenario analysis based on closing data as of September 11, 2026, historical prices and technical indicators. It does not constitute investment advice or a definitive forecast of future prices.

① Key Technical Levels

② Scenarios for the Coming Week (Subjective Weights, Not Statistical Probabilities)

• Range-bound consolidation (relatively high subjective weight, approximately 60%; a subjective heuristic judgment based on the current technical pattern and capital flows, not a statistical probability): The price range would be approximately RMB 5.14–5.35. The trigger would be buying support around RMB 5.14–5.20 without an effective breakout above the RMB 5.28–5.40 resistance zone. Daily trading value would generally remain around RMB 30–50 million, with no major catalyst. The market could see continued bullish-bearish competition around the MA20 and Bollinger midline.
• Weak downward move (medium weight; a subjective judgment based on the current technical pattern and capital flows, not a statistical probability): The price range would be approximately RMB 4.94–5.14. The trigger would be an effective closing break below RMB 5.14 accompanied by trading value above the recent average, or consecutive net outflows from major investors. If the machinery-equipment sector and broader market weakened simultaneously, pressure to test the RMB 4.94–5.03 support zone could increase. If RMB 4.94 also failed, attention would need to turn to a further decline toward the previous low area.
• Stronger rebound (low weight but cannot be completely excluded; a subjective judgment based on the current technical pattern and capital flows, not a statistical probability): The price range would be approximately RMB 5.28–5.50. The trigger would be a renewed move above RMB 5.28 followed by a high-volume breakout above RMB 5.40, with trading value clearly exceeding the recent average of approximately RMB 42 million for one or two consecutive trading days, preferably reaching more than RMB 60 million, and major capital flows shifting from outflows to sustained net inflows. Without confirmation from volume and capital flows, a one-day surge should not be directly defined as a trend reversal.

③ Capital and Liquidity Background

As of September 11, 2026, daily trading value was approximately RMB 44.62 million and turnover was 1.55%. From September 7 to 11, trading value was approximately RMB 37–51.4 million and turnover was approximately 1.21%–1.73%, with average trading value of approximately RMB 41.88 million and average turnover of approximately 1.43% over the latest five trading days. As of June 30, 2026, Tonghuashun data showed that 61 major institutional investors held approximately 248.7 million shares, representing approximately 44.76% of tradable A-shares, including 59 funds, one QFII and one general corporate entity. Public funds and UBS AG appeared among the top 10 tradable shareholders, while the largest shareholder, Changzhou Investment Group Co., Ltd., held approximately 227.66 million shares, representing approximately 32.26% of total shares outstanding. These shareholder-structure data have a quarterly lag, and the actual tradable float may have changed in the third quarter. Given total market capitalization of approximately RMB 3.663 billion and low-to-medium turnover, short-term prices may be relatively susceptible to daily capital flows and sector sentiment, but this cannot be used to infer current specific holdings changes.

A volume confirmation signal to monitor is the following: if daily trading value expands to more than RMB 60 million for several consecutive days during the coming week, while the price holds above RMB 5.28 and subsequently breaks above RMB 5.40, this could be regarded as a signal of stronger short-term capital participation and breakout validity. If trading value expands while the price falls below RMB 5.14, the move would more closely resemble high-volume profit taking or selling-pressure release.

④ Points to Monitor (Observation Ideas Only, Not Trading Instructions)

• Observe whether the RMB 5.14–5.20 support zone holds; if it fails, monitor the RMB 4.94–5.03 strong-support zone. This is an observation idea, not a trading instruction.
• Observe whether the RMB 5.28–5.40 resistance zone can be broken with support from trading value. This is an observation idea, not a trading instruction.
• Observe whether trading value can rise from the recent average of approximately RMB 42 million to above RMB 60 million and remain there for at least one or two trading days. This is an observation idea, not a trading instruction.
• Observe whether major capital flows shift from the early-September outflow bias to consecutive net inflows. This is an observation idea, not a trading instruction.

The above scenario analysis is based on closing data as of September 11, 2026, historical prices and estimated technical indicators. Short-term share prices will also be affected by news, capital flows, the broader market and other factors. Technical indicators themselves have lagging effects and limitations. This does not guarantee actual future performance or constitute a buy or sell recommendation. Investors should make independent judgments based on the latest market information and bear their own investment risks.

6. Industry Landscape and Competitor Analysis

6.1 Industry Conditions

Suchangchai operates in the internal-combustion-engine and parts manufacturing industry, with downstream exposure to agricultural machinery, construction machinery, generator sets, marine engines and commercial vehicles. The industry is affected by agricultural-machinery subsidies, equipment renewal, construction-machinery cycles, exports and emissions regulations. Traditional diesel-engine market growth is slowing, with stronger characteristics of replacement demand and structural upgrading. The China IV off-road emissions standard has raised barriers to product development, emissions control and supporting certification. The industry is evolving toward high efficiency, intelligence, hybrid systems, gas engines and hydrogen internal-combustion engines.

6.2 Competitive Landscape

• Agricultural-machinery demand has been pressured by low grain prices, abnormal weather and declining operating returns for users. Traditional agricultural-machinery demand is shifting from incremental expansion toward replacement demand, while large tractors, powershift transmissions, smart agricultural machinery, exported agricultural machinery and machinery for hilly and mountainous areas are performing relatively better.
• Leading enterprises are increasing market concentration through brand, technology, channel and scale advantages, placing greater competitive pressure on smaller and medium-sized companies.
• According to the China Internal Combustion Engine Industry Association, the 10 largest companies, including Weichai, Yuchai, Quanchai, Yunnei, Xinchai, YTO, Dongfeng Cummins, FAW Jiefang Power, Xindongli Technology and Jiangling, together accounted for approximately 79.02% of multi-cylinder diesel-engine sales in March 2026. This is a multi-cylinder diesel-engine statistic and cannot be directly equated with Suchangchai’s market share in single-cylinder and small- and medium-power diesel engines.
• Suchangchai’s competitive advantages are concentrated in single-cylinder and small- and medium-power diesel engines, supporting power for agricultural machinery and generator sets, the Changchai brand, a relatively complete product range, nationwide sales and after-sales networks, and synergies between in-house casting and engine assembly.
• The company disclosed that its single-cylinder products have relatively high market shares, with certain power ranges ranking among the top in China. The 2023 annual-report summary stated that market share in certain power ranges ranked first nationally. However, the 2025 annual report did not disclose specific market shares or corresponding power ranges. This statement mainly originates from the company’s annual reports and lacks independent external cross-verification; it should not be generalized to mean that the company ranks first in the entire diesel-engine industry.
• The company has an after-sales network comprising 24 sales and service centers and 746 authorized repair stations. As of the end of 2025, it held 209 valid domestic and overseas authorized patents, including 42 domestic invention patents and four overseas invention patents, and received 32 new patent grants in 2025.

6.3 Major Competitors

Suchangchai overlaps most with Quanchai Power and Xinchai in off-road diesel engines, agricultural machinery and generator-set power, but Suchangchai is more focused on single-cylinder and small- and medium-power markets. Compared with Yunnei Power, it has lower exposure to vehicle and multi-cylinder power. Compared with YTO Group, Suchangchai is mainly positioned as an engine supplier rather than an agricultural-machinery whole-machine manufacturer. Weichai Power is primarily an industry leader and technology-upgrade benchmark in high-power diesel engines. Overall, Suchangchai’s relative advantages derive from its accumulated expertise in single-cylinder and small- and medium-power products, the Changchai brand, specialized channels and casting synergies. Its main weaknesses are relatively high downstream customer concentration, sensitivity to upstream costs, low gross margins and a lack of independent external verification of certain market-share claims and the commercialization of new technologies.

7. Risk Factors

• High concentration in the core diesel-engine business: Diesel-engine revenue accounted for 92.25% of operating revenue in 2025. If demand for agricultural machinery, construction machinery or generator sets is affected by agricultural-machinery subsidies, equipment renewal, weather, grain prices or investment cycles, the company’s overall revenue and profit may come under simultaneous pressure.
• Significant impact of raw-material costs on profitability: Raw materials accounted for 78.01% of the relevant operating costs of diesel and gasoline engines in 2025, while energy costs increased 22.37% year on year. If steel, castings, components or energy costs rise and the company cannot pass them through to downstream customers in a timely manner, diesel-engine gross margin may face further pressure.
• Relatively high customer concentration and strong downstream bargaining power: The five largest customers accounted for 44.40% of sales in 2025, and the largest customer accounted for 25.58%. OEM customers have strong bargaining power over price, emissions, reliability and delivery. Changes in orders or collections from major customers could significantly affect operating performance.
• Risk of long-outstanding receivables and concentrated collections: At the end of 2025, the book balance of accounts receivable was RMB 595 million, including RMB 135 million aged more than three years and RMB 130 million aged more than five years. The five largest accounts-receivable customers accounted for 60.63% of the balance, while the largest customer accounted for 45.10%. If collections fall short of expectations, bad-debt losses and working-capital occupation could increase.
• Mismatch between cash flow and profit: Net cash flow from operating activities was negative RMB 134.71 million in the first half of 2026, with the negative amount further expanding from the same period a year earlier. Although attributable net profit was RMB 105.06 million during the same period, profit was still supported by non-core factors such as share disposals, bank dividends and cash-management income. The quality of cash conversion from core earnings remains uncertain.
• Relatively weak core earnings base: Attributable net profit increased 174.86% year on year in 2025, but attributable net profit excluding non-recurring items declined 61.15%. As of September 11, 2026, forward P/E was approximately 44x and forward P/E excluding non-recurring items was approximately 73–75x. If growth in adjusted profit cannot be sustained, the valuation may face significant pressure.
• Uncertain short-term contribution from new businesses and the industrial investment fund: Hybrid powertrains and hydrogen internal-combustion engines remain at the R&D or product-reserve stage. Although the industrial investment fund in which the company participated has completed registration, no specific investee projects, project returns or direct contribution to profit have been disclosed. Investment and returns may fall short of expectations.
• Uncertainty regarding the timing and amount of housing-expropriation compensation: The Sanjing branch has cumulatively received the first compensation payment of RMB 30 million. The casting plant involves compensation of RMB 346.8569 million, but a formal agreement had not been signed as of the interim-report disclosure date. Future compensation payments, asset-disposal gains and production-layout impacts depend on the signing of the agreement, payment of funds and accounting-recognition progress.
• Weak short-term trading structure and relatively limited liquidity: As of September 11, 2026, the share price was below the MA5 and MA10, major capital flows were biased toward outflows in early September, and average trading value and turnover over the latest five trading days were approximately RMB 41.88 million and 1.43%, respectively. If the RMB 5.14–5.20 support zone fails, the price may test RMB 4.94–5.03, although technical indicators are lagging and cannot support definitive conclusions.

8. Conclusion and Outlook

The improvement in Suchangchai’s fundamentals is mainly reflected in moderate revenue growth in the first half of 2026, growth in adjusted profit exceeding revenue growth and higher comprehensive gross margin, indicating some improvement in product mix, cost control or operating efficiency. Future growth will depend on changes in replacement demand for agricultural machinery, equipment renewal and exports, as well as whether the volume ramp-up of high-horsepower and higher-value-added products, casting synergies, procurement cost reductions and improved overseas-channel profitability can be sustained. The industrial investment fund provides the company with a channel to position itself in the new-energy and next-generation information-technology value chains, but it has not yet produced identifiable incremental core-business revenue or investment gains.

The company remains constrained by slowing growth in traditional diesel-engine demand, relatively high customer concentration, a high raw-material cost share and gross-margin volatility. In 2025, the largest customer accounted for 25.58% of sales and the five largest customers accounted for 44.40%. At the same time, long-outstanding receivables and negative operating cash flow indicate that the conversion of revenue growth into cash collections remains insufficient. Given forward P/E of approximately 44x and relatively high adjusted valuation, the market’s focus will be on whether core earnings can continue to improve, whether cash flow can recover and whether the contribution of non-recurring gains to profit can decline.

Technically, the share price is currently in a pullback phase after a surge. The key short-term points to monitor are whether the RMB 5.14–5.20 area can hold and whether the RMB 5.28–5.40 resistance zone can be broken with a clear increase in trading value. If support fails, attention should turn to RMB 4.94–5.03. These price ranges reflect only the technical structure as of September 11, 2026 and do not represent a definitive forecast of future performance.
