Conservative Entry: $45.34 Current Price: $48.70 Extension: +7.4% vs. conservative entry Breakout Level: $45.34 (Conservative Entry)

Classification: CONFIRMED-ACTIVE

2. Thesis Layer

Primary Secular Thesis: AI Infrastructure → Power / Grid / Electrical (Tier Tertiary, Confidence Low) Thesis Context: The company is positioned as a beneficiary of the AI Infrastructure thesis, specifically within the Power and Grid sub-sector. The direct link is the demand for reliable backup power generation for data centers.

• Directness: The company is a direct beneficiary of this trend. Management explicitly stated that combined sales of MTU Yuchai Power and Yuchai branded high-horsepower engines to data centers exceeded 2,000 units in 2025, a significant increase from 750 units in the prior year.
• Additional Tailwinds: While the AI thesis is the primary secular driver noted in the setup, the company also benefits from the broader "New Quality Productive Forces" and green transition mandates outlined in China's 15th Five-Year-Plan (2026-2030), which prioritizes low-carbon transitions and mandates emission reductions. This provides a secondary structural tailwind for their engine portfolio, particularly in the heavy-duty and marine sectors.

3. Business Overview

Company Profile: China Yuchai International Limited (CYD) is a global manufacturer of diesel, natural gas, and alternate fuel combustion engines, as well as new energy powertrain systems. Headquartered in Singapore with operations in China, the company serves a diverse range of applications including trucks, buses, passenger vehicles, marine vessels, industrial equipment, and agricultural machinery.

Business Model & Performance (As of 2026-06-13):

• Revenue Growth: For the fiscal year 2025, revenue increased by 28.9% to RMB 24.7 billion (USD 3.5 billion).
• Unit Sales: Engine sales volume surged 29.4% in 2025 to 461,309 units, up from 356,586 units in 2024.
• Segment Performance:
• Data Center Power: Sales to data centers exceeded 2,000 units in 2025, driven by the need for reliable backup power.
• Commercial Vehicles: Heavy-duty truck engine sales increased 80.1% year-over-year in 2025. Medium-duty and light-duty engine sales grew 34.2% and 67.6% respectively.
• Market Share: Truck and bus engine units rose 42.8% compared to CAAM data for vehicle market sales growth (excluding gasoline and electric vehicles), which grew only 4.5% in 2025.
• Capacity & Expansion: Management confirmed that production capacity expansion is "well underway" to meet the expected increase in demand for power generating engines.
• Strategic Moves: In January 2026, the indirect subsidiary, Guangxi Yuchai Marine and Genset Power Company, filed an application for listing with the Hong Kong Stock Exchange.
• Customer Concentration: Sales to the top five customers accounted for 35.5% of total revenue in 2025, with the top customer (a leading Chinese automobile manufacturer group) accounting for 17.1%.

4. Archetype and Conviction

Archetype: Quality Compounder Rationale: The company fits the "Quality Compounder" archetype due to its consistent ability to grow revenue and unit sales while expanding margins.

• Margin Inflector: Gross margin rose to 16.5% in 2025, indicating improved operational leverage or pricing power amidst the volume surge.
• Structural Quality: The ATR at breakout was 3.6% (productive), suggesting a clean structural move. The current ATR of 6.5% (very high) reflects the volatility associated with the rapid growth in the data center and commercial vehicle sectors.
• Conviction Stack:
• Thesis Strength: Moderate. The AI/Power thesis is "Tier Tertiary" with "Low" confidence in the setup metadata, but the *evidence* of actual sales to data centers (2,000+ units) is concrete and material.
• Evidence Quality: High. The evidence block contains multiple primary and beneficiary citations from earnings transcripts and SEC filings dated prior to the event date, confirming the growth narrative with specific numbers.
• Structural Quality: The setup is confirmed with a wide stop ($34.54) relative to the entry, providing a favorable risk/reward profile for a confirmed breakout.
• Rerating Potential: The combination of high growth (28.9% revenue, 29.4% unit sales) and margin expansion (16.5% gross margin) suggests potential for multiple expansion, supported by the "New Quality Productive Forces" policy tailwinds.

5. Invalidation, Strengthening, and Gaps

Invalidation Triggers:

• A significant reversal in the data center engine sales trend (e.g., a drop in orders or a delay in capacity expansion) would weaken the primary thesis.
• Failure to execute the planned capacity expansion or the Hong Kong listing of the subsidiary could signal execution risk.

Strengthening Factors:

• Continued acceleration in data center engine sales beyond the 2,000-unit baseline.
• Successful listing of the Guangxi Yuchai Marine and Genset Power Company subsidiary, which could unlock capital for further expansion.
• Further margin expansion as the company scales production to meet the "well underway" capacity expansion.

Evidence Gaps:

• Valuation Context: While the financial spine provides forward consensus EPS (FY1: 21.84, FY2: 28.17), specific P/E or P/S multiples relative to historical averages or peers are not explicitly detailed in the provided evidence block, limiting a precise valuation comparison.
• Geopolitical Exposure: The evidence mentions global operations but does not explicitly detail the impact of current or potential trade restrictions on the company's international sales or supply chain, which is a material risk for a Chinese manufacturer.
• NEV Transition Impact: While the company is developing new energy powertrains, the specific revenue contribution or margin impact of these new energy products versus the core diesel/natural gas business is not quantified in the provided evidence.

PRIVATE ANALYST CALL

Judgment: Buy Confidence: medium Key risks: High current ATR (6.5%) indicates elevated volatility; Customer concentration risk (top 5 customers = 35.5% of revenue); Regulatory and geopolitical headwinds for Chinese manufacturers; Execution risk on capacity expansion. Sizing hint: Moderate position size due to very high current ATR; reduce size if volatility spikes further. Expected path: Management expects demand to continue rising, driving capacity expansion and further sales growth; the subsidiary listing may provide additional capital for R&D and expansion. Expected horizon: 12 to 24 months for the thesis to fully play out as capacity comes online.
