Global AI Power Peers' 2Q26 Results Confirm AIDC Prosperity; Weichai Reiterates Buy Rating

Overview

This is an earnings commentary report on Weichai Power released by Goldman Sachs. The core focus is not on Weichai's own Q2 results, but rather on validating the prosperity and investment logic of Weichai's AIDC power business by reviewing the latest Q2 earnings and management commentary from its global peers in the AI data center power generation equipment sector—Cummins, Caterpillar, INNIO, Wärtsilä, Generac, and Bloom Energy. The report's core conclusion is that the global AIDC power generation equipment industry is in a strong prosperous phase characterized by sustained supply shortages, order backlogs extending years into the future, and favorable pricing environments. Weichai, benefiting from a shorter capacity expansion cycle and a complete product portfolio covering diesel backup power, gas primary power, and SOFC fuel cell primary power, is a key beneficiary of this trend, warranting a reiterated Buy rating.

Core views

The report first conveys a highly consistent signal from global peers: AIDC power demand is extremely strong with no signs of slowing down. Cummins, Caterpillar, INNIO, Wärtsilä, Generac, and Bloom Energy all achieved robust growth in their AIDC power businesses in 2Q26, with revenue growth rates generally ranging from double-digit to triple-digit percentages. Management teams across multiple companies explicitly stated that data center backup power demand is "exceptionally strong and still growing," with no observed signs of customers shifting to zero-backup configurations. Notably, nearly all companies emphasized the rapid rise in behind-the-meter site primary power demand, as hyperscale cloud providers seek to bypass grid connection bottlenecks and accelerate data center deployment. INNIO, Cummins, Wärtsilä, and Bloom Energy all secured gigawatt (GW)-scale primary power projects this quarter. Supply constraints are currently the more prominent contradiction. Caterpillar, Cummins, and INNIO have all indicated that capacity, rather than demand, is the main bottleneck, with order books and capacity schedules extending through 2028-2031. Caterpillar has comprehensively extended delivery cycles, with gas primary power engines scheduled until late 2028 to 2029, and diesel backup generators booked through 2028. Bloom Energy highlights "short delivery cycles" as a key advantage over internal combustion engine competitors, with management noting that customers are willing to pay a premium for faster commissioning. On the pricing front, the imbalance between supply and demand and long lead times support a favorable pricing environment: Caterpillar introduced contract price escalation clauses for long-cycle orders, INNIO's recent order margins were better than historical averages, Generac emphasized that market pricing remains at high levels, and Bloom noted that customers are paying for "time to power" (rapid energization capability) and advanced features rather than just commoditized kilowatts. Capacity expansion is accelerating across the board: Caterpillar restarted its 10MW medium-speed gas reciprocating engine platform (halted in 2022), expecting shipments to begin in 4Q26 and adding 1.5GW of capacity; INNIO plans to increase capacity from 3.5GW in 2025 to approximately 10GW by 2030; Wärtsilä added a EUR 90 million investment, increasing total capacity by 65% compared to 2025; Generac plans to triple its data center-related capacity within the next 12 months; Cummins reaffirmed its plan to add 20GW of new capacity across the entire supply chain, with partial production starting in 2027, significant ramp-up in 2028, and continuation through 2030. Mapping these insights to Weichai Power, the report argues that the investment narrative has shifted from heavy trucks to AI data center power generation. Currently, the AIDC power business accounts for approximately 12% of Weichai's expected net profit in 2025. Goldman Sachs estimates that this business will grow by roughly 10 times by 2030, with its profit contribution rising to over 43% of total profits and contributing more than 60% of incremental EPS growth before 2030. Compared to overseas peers, Weichai's advantages lie in its shorter capacity expansion cycle and its comprehensive product portfolio spanning diesel large-bore engines (backup power), gas reciprocating engines (primary/backup power), and SOFC fuel cells (emerging on-site power). This positions it favorably in an environment of supply shortages and spillover orders.

Analysis framework

The report employs a 'peer read-across' analytical approach: since Weichai's key investment logic hinges on the high growth of its AIDC power business, the latest operating data and management commentary from global top-tier peers serve as external evidence to validate whether this logic holds. The report follows the主线 (main thread) of 'Demand-Supply-Pricing-Capacity Expansion', systematically organizing the earnings highlights, orders/backlog/lead times, pricing environments, and capacity plans of six overseas peers. These signals are then unified into the conclusion that 'global AIDC power generation equipment is in a state of supply shortage with sustained prosperity.' Finally, this industry judgment is transmitted back to Weichai's own investment logic: in such a tight supply-demand landscape, Weichai's shorter expansion cycle and more complete product portfolio offer relative advantages, supporting its Buy rating and SoTP (Sum-of-the-Parts) segment valuation. In terms of valuation, Goldman Sachs uses the Sum-of-the-Parts (SoTP) method. Traditional businesses are valued at 12x the average EPS for 2026-27 (a mid-cycle P/E ratio). The three AIDC businesses are valued separately: diesel large-bore engines at 25x 2028 P/E, gas primary power at 30x 2030 P/E, and SOFC at 51x 2030 P/E. These values are discounted back to mid-2027 using a 9% cost of equity, resulting in a baseline H-share target price of HK$56. Assuming an A-share discount of 6% relative to H-shares, the A-share target price is derived as RMB 48.

Methodology notes

• Industry/Industrial Analysis FrameworkSupply-demand framework

  The prosperity of the AIDC power generation equipment industry is determined by both supply and demand sides. The report focuses on observing orders, backlog, lead times, capacity, and prices to determine whether the industry is in a state of supply shortage or oversupply.

  By analyzing order backlogs, the degree of extended lead times, and the pace of capacity expansion across various companies, the report determines that the current AIDC power generation equipment market is in a prosperous stage of supply shortage and strong demand. This is a typical method of judging industry positioning by contrasting supply and demand sides.

• Industry/Industrial Analysis FrameworkUpstream-Midstream-Downstream Transmission in the Value Chain

  Judging the prosperity level of the entire AIDC power generation equipment chain through the operating data of global peers (similar equipment suppliers in the value chain) and mapping it to Weichai Power.

  The report does not analyze Weichai in isolation but uses the performance and orders of six global peers to 'validate' industry demand, then transmits this industry prosperity to Weichai's own business. This is a practice of inferring individual stock investment logic from successful cases of peer companies.

• Valuation MethodSOTP Segment Valuation

  Sum-of-the-Parts valuation method, where different business segments of a company are valued separately and then summed up.

  Weichai's traditional businesses (heavy trucks, agricultural machinery, etc.) and AIDC power generation business are at completely different stages of growth. Using a single P/E ratio makes it difficult to accurately reflect value. Therefore, Goldman Sachs assigns different multiples to traditional businesses and the three types of AIDC power products, discounts them, and sums them up to derive the target price. This better captures the value differences among businesses with varying growth potentials.

• Company Fundamentals and Financial FrameworkProfit Quality Analysis

  Examining the sustainability of rapid profit growth and its impact on the overall profit structure.

  The report focuses on whether the AIDC business, currently accounting for only 12% of net profit, can contribute over 43% of overall profit in the future and drive more than 60% of incremental EPS growth. This is essentially analyzing the improvement in profit structure quality and the switch in growth engines, rather than just looking at total volume growth.

• Cycle and Prosperity FrameworkProsperity Turning Point Analysis

  Identifying the prosperity turning point where the industry shifts from the traditional heavy truck logic to the AI data center power generation logic.

  The report believes that Weichai's investment narrative has shifted from the heavy truck cycle to the growth logic of AI data center power generation. This 'narrative shift' is essentially about judging whether the turning point for the company's profit drivers has arrived and whether the market should re-rate the stock.

Asset mapping & comparison

Structured mapping from thesis to named assets (strengths, weaknesses, peers, risks).

• Weichai Power (000338.SZ / 2338.HK)

  Direct beneficiary of global AIDC power supply shortage: possesses a shorter capacity expansion cycle and a complete product portfolio covering diesel backup/gas primary power/SOFC primary power.

  Strengths

  Complete product portfolio, shorter capacity expansion cycle than overseas peers, approx. 20% market share in China's multi-cylinder engine market, diversified business (heavy trucks, agricultural machinery, intelligent logistics) providing earnings buffer.

  Weaknesses

  AIDC power business is currently small in scale (approx. 12% of 2025 net profit), traditional heavy truck business remains affected by macroeconomic and real estate prosperity.

  Comparison

  Compared to overseas peers like Caterpillar, Cummins, and INNIO whose lead times are already booked to 2028-2031, Weichai's shorter expansion cycle means it can respond to customer demands faster in an environment of spillover orders.

  Risks

  Macro activity (road freight, infrastructure, real estate) weaker than expected; power business development slower than expected; heavy truck engine market share performance weaker than expected.

• Caterpillar (CAT)

  Representative peer reflecting AIDC power demand prosperity: orders booked to 2029/2030, lead times comprehensively extended, restarting halted platforms to accelerate capacity expansion.

  Strengths

  Full product line coverage, pricing includes contract escalation clauses to protect long-cycle orders, FY26 revenue guidance raised to mid-to-high double digits.

  Weaknesses

  Lead times comprehensively extended to 2028-2029, some customers switching to smaller products due to supply shortages, capacity becoming the main constraint on growth.

  Comparison

  As a leader in internal combustion engine power generation equipment, its capacity bottlenecks and long lead times instead highlight the relative advantages of manufacturers like Weichai that can expand capacity faster.

  Risks

  If AI data center demand slows down, high order volumes and capacity expansions may face digestion pressure.

• Bloom Energy (BE)

  Representative of the SOFC fuel cell route, validating the on-site primary power and 'rapid energization' premium logic.

  Strengths

  Delivery cycles significantly shorter than internal combustion engine competitors (months vs. years), products validated and recognized by major US cloud providers, revenue and guidance substantially raised.

  Weaknesses

  Capacity and raw material (scandium) supply rely on domestic US expansion, still in a high-growth investment phase.

  Comparison

  Securing orders based on short lead times and advanced features (load tracking, carbon capture ready) rather than simply competing on price is a differentiated advantage of the SOFC route relative to internal combustion power generation.

  Risks

  If raw material supply chains (e.g., scandium) are restricted or capacity expansion execution falls short of expectations, it may suppress deliveries and gross margins.

• Generac (GNRC)

  Comparable benchmark for large generator sets/data center backup power, validating backup power demand and market share logic.

  Strengths

  Data center backlog reached $1.6 billion, new orders in the last 90 days approx. $1 billion, lead times of 40-45 weeks significantly lower than the industry average of 70-80 weeks.

  Weaknesses

  Relatively small capacity scale, adopting a strategy of grabbing market share with short lead times rather than commanding higher-than-market pricing.

  Comparison

  Similar to Bloom, it uses delivery speed as a differentiation tool rather than relying solely on pricing premiums; this highlights the industry rule that 'delivery capability is competitiveness'.

  Risks

  If demand grows beyond expectations while capacity expansion lags, it may limit its ability to capture higher pricing power.

Impact & implications

The report believes that the high consistency of information from global top-tier peers means that AIDC power generation equipment is in a multi-year supply shortage cycle, with backlogs extending to 2028-2031 and favorable pricing environments. For Weichai Power, this industry background provides clear positive validation: although its AIDC power business is currently small (accounting for approx. 12% of net profit in 2025), in an environment of supply shortages and constrained capacity among overseas manufacturers, Weichai's shorter capacity expansion cycle and complete product portfolio covering diesel backup power, gas primary power, and SOFC position it to potentially accelerate order acquisition and market share gains. Based on this, Goldman Sachs reiterates its Buy rating for A-shares and H-shares, maintaining target prices of RMB 48 for A-shares and HK$56 for H-shares, believing that Weichai is transitioning from a heavy truck cyclical stock to an AI data center power generation growth stock, presenting re-rating potential.

Risks

• Macro activity (especially road freight, infrastructure, and real estate) weaker than expected, dragging down Weichai's traditional engine and vehicle businesses.
• Global economic growth weaker than expected.
• Accelerated penetration of powertrains towards higher electrification and LNG penetration rate lower than expected.
• Heavy truck engine market share performance weaker than expected.
• Power business (AIDC-related) development slower than expected.

What to watch

• Order acquisition speed, capacity expansion pace, and profit contribution changes for Weichai's AIDC power business.
• Whether the global AIDC power generation equipment supply-demand situation remains tight (changes in peer lead times, backlog orders, pricing environments).
• Customer validation and commercialization progress for Weichai's emerging businesses such as SOFC and gas primary power.
• Recovery of macro demand for traditional heavy trucks, agricultural machinery, and logistics sectors.
