Goldman Sachs Maintains Weichai Buy, Raises Target to RMB 42 as AI Data Center Power Generation Becomes a New Growth Engine

Overview

Goldman Sachs issued an earnings commentary following Weichai Power’s Q1 2026 results, maintaining a Buy rating on both A‑ and H‑shares while raising their respective target prices to RMB 42 and HKD 46. The core argument is that Weichai’s investment thesis has undergone a structural shift, moving from cyclical heavy‑duty truck engine operations to the high‑growth AI data center power generation segment. Its 2027–2030 EPS forecasts were increased by 3–6%, primarily reflecting faster‑than‑expected shipments of gas generator sets.

Core views

Earnings and Forecast Adjustments: The 2026 EPS forecast remains largely unchanged, but the 2027–2030 projections have been raised by 3–6%. The 12‑month target price is based on a 22x multiple of the 2026–2027 average EPS, representing a shift from the previous practice of valuing the company against a single fiscal year’s EPS. The A‑share target assumes virtually no discount or premium relative to the H‑share, consistent with trading patterns over the past two to three quarters. Shift in Investment Thesis: Weichai Power’s primary growth driver is transitioning from heavy‑duty truck engines to the AI data center power generation business. The company has built a comprehensive technology portfolio encompassing diesel generator sets (for data center backup power), gas generator sets (for on‑site primary/backup power), and fuel cells (an emerging on‑site power solution). The AIDC power generation business currently accounts for 12% of the projected 2025 net profit and is expected to grow roughly tenfold by 2030, with its profit contribution more than tripling to 43%, driving over 60% of the incremental EPS growth through 2030. Industry Trend Validation: Caterpillar’s Q1 results indicate accelerating adoption of reciprocating engines as primary power solutions for AI data centers. Caterpillar has scaled up its reciprocating engine capacity expansion plan from a previous doubling to roughly triple the 2024 level and has already secured six gigawatt‑scale primary power orders for data centers. Combined with INNIO’s approximately 5 GW and Wärtsilä’s roughly 2.4 GW of orders, industry‑wide reciprocating engine commitments for AI data center primary power have reached around 15 GW over the past six months.

Analysis framework

Goldman Sachs employs an analytical framework where a shift in narrative drives a revaluation. When a company’s core growth engine transitions from a low‑multiple cyclical business (heavy‑duty truck engines) to a high‑multiple growth business (AI data center power generation), the market assigns a higher valuation multiple. In this report, the target valuation multiple is set at 22x the 2026–2027 average EPS, about 100% above the long‑term cyclical median of roughly 11x, to reflect this transition. Benchmarking Against Peers’ Revaluations: Goldman Sachs compares Weichai’s target valuation multiple to the revaluation patterns observed among global engine peers over the past year, while also factoring in Weichai’s power generation business’s stronger growth profile relative to its peers to ensure the reasonableness of its assumptions. The targeted 2026/2027 P/E multiple aligns with the average level seen among global power equipment peers. Revenue and Margin Decomposition Methodology: The report disaggregates the power generation business by product segment—large‑bore diesel engines, SOFCs, and gas generator sets—projecting volumes and unit margins for each, analyzing sales, per‑unit profits, and changes in share across product lines to bolster the credibility of the overall earnings forecast.

Methodology notes

• Valuation MethodologyPE/PEG valuation

  P/E valuation based on average EPS

  This report uses the 2026–2027 average EPS rather than a single fiscal year, which smooths out cyclical fluctuations and is better suited to companies undergoing structural transformation.

• Company Fundamentals and Financial Framework

  Narrative Shift Drives Valuation Reassessment

  When a company’s core growth engine shifts from a low‑multiple cyclical business to a high‑multiple growth business, the market assigns a higher valuation multiple. This logic is applied here to Weichai’s transition from heavy trucks to AI data center power generation.

• Industry/Industrial Analysis Framework

  Peer Revaluation Benchmarking

  Comparing the target company’s valuation multiple changes to those of global peers over the past year ensures the reasonableness and market consistency of valuation assumptions.

• Weichai Power (000338.SZ/02338.HK)

  Primary beneficiary; rapid growth in the AI data center power generation business drives the revaluation

  Strengths

  Comprehensive technology portfolio (diesel/gas generator sets, fuel cells); power generation business exhibits a stronger growth profile than global peers

  Weaknesses

  Traditional heavy‑duty truck engine business still accounts for a significant share; cyclical volatility may weigh on overall performance

  Comparison

  The valuation multiple of 22x matches the global peer average for power equipment, yet its growth trajectory is more robust

  Risks

  Macroeconomic slowdown, rising electrification penetration, underperformance in the power generation business

Impact & implications

Goldman Sachs believes Weichai Power’s investment thesis has undergone a structural shift, moving from cyclical heavy‑duty truck engines to the high‑growth AI data center power generation business. This transformation warrants a revaluation, with the target multiple about 100% above the long‑term median. The power generation business will drive over 60% of the incremental EPS growth through 2030. For investors, it will be important to monitor the company’s ability to secure ongoing AIDC power generation orders, the progress of gas generator set shipments at the gigawatt scale, and whether the heavy‑duty truck engine business drags down overall performance.

Risks

• Slowdown in macroeconomic activity, particularly in road freight, infrastructure, and real estate
• Weakness in global economic growth
• Transition of powertrains toward higher electrification and lower LNG penetration
• Underperformance in heavy‑duty truck engine market share
• Slower-than-expected development of the power generation business

What to watch

• Progress of gas generator set shipments at the gigawatt scale
• Order intake in the AI data center power generation business
• Changes in heavy‑duty truck engine market share
• Trends in LNG engine penetration
