Envicool Deep-Dive Research

What really shaped the company was management's background, rather than that initial RMB 1 million in capital. The 2025 annual report discloses that chairman and general manager Qi Yong previously worked at Huawei Electric and Emerson, while several core executives came from Liebert, Emerson, Midea, Huawei Electric, Foxconn, and other companies. This is a typical network-energy, precision-cooling, and industrial-equipment talent mix, not an internet-style founding team. It explains why Envicool later became good at selling high-reliability, long-validation-cycle, complex-application thermal-control solutions to major customers, instead of building a traffic gateway. Qi Yong serves as both chairman and general manager. The annual report says the company balances this through the board and independent-director system. That structure improves execution efficiency and also brings key-person risk.

Envicool listed on the SZSE SME Board on December 29, 2016, at an issue price of RMB 18 per share, issuing 20 million shares and raising net proceeds of about RMB 309 million. The IPO story told to the market was still traditional but solid: a precision thermal-control energy-saving equipment manufacturer replicating technology and customer capabilities across communications, data centers, bus air conditioning, and other scenarios. At the moment of listing, the market had not yet given it today's AI premium. Envicool then looked more like a manufacturing growth stock.

Development Stages and Key Milestones

Envicool's development can be divided into four clear stages.

The first stage, from 2005 to 2016, was product validation. The early customer list already revealed its commercial character. The prospectus listed customers and application scenarios including Huawei, ZTE, China Unicom, China Mobile, China Telecom, BYD, Yutong, King Long, and CATL. In other words, from the start it built products along outdoor cabinets, communications networks, data centers, and new-energy vehicles, all scenarios with rigid thermal-management requirements, rather than starting from a single track. Its edge at the time was a willingness to do hard engineering work and deliver high-reliability customer scenarios. It was not yet a full-chain liquid-cooling company.

The second stage, from 2017 to 2020, was category expansion. In 2018, Shanghai Cooltech became a wholly owned subsidiary, taking Envicool into rail-transit train air conditioning and adding metro train air-conditioning and overhaul-service businesses. This move resembled a common manufacturing-company boundary expansion: extending environmental-control technology from equipment rooms into rail transit, rather than chasing a new story. After 2018, the company did not narrow its business lines. It continued to run room thermal control, cabinet thermal control, energy-storage thermal management, vehicle air conditioning, and rail-transit air conditioning in parallel, gradually forming platform-style thermal-management capabilities. Shanghai Cooltech's addition still has aftereffects today. The rail-transit business gave Envicool more service and maintenance capability, but it is dragged by local fiscal conditions and metro investment cycles, adding a low-demand, low-elasticity piece to the profit structure.

The third stage, from 2020 to 2023, was a second acceleration. The company launched a private placement in 2020 and completed it in 2021, issuing 12.0797 million new shares at RMB 25.58 per share and raising net proceeds of about RMB 302 million for the South China headquarters base and R&D and manufacturing capacity. This node was important because it was typical growth-capacity financing, not distress financing. At the same time, in 2023 the company included cold-plate products in the Intel Eagle Stream server Design Guide. Quick-disconnect connectors, Manifolds, cold plates, liquid-cooling fluids, leak detection, and other products in the Coolinside full-chain liquid-cooling solution were recognized by mainstream compute-chip vendors and leading compute-equipment manufacturers and began scaled procurement. Liquid-cooling electronic thermal-dissipation chain products had already begun making a meaningful revenue contribution in 2023. By this point, Envicool finally began growing from a thermal-control equipment manufacturer into a capital-market identity as a compute liquid-cooling chain supplier.

The fourth stage, from 2024 to today, is the AI narrative uplift and reality recalibration. Revenue stepped up again in 2025, room thermal control grew 41.28% year over year, overseas revenue grew 52.64%, and management emphasized overseas business expansion, global supply-chain platform construction, and acceleration in electronic thermal dissipation during earnings communication. But the Q1 2026 report also laid out the other side: between order growth, project progress, and revenue recognition, an equipment company is still governed by acceptance, collection, exchange rates, and financing costs. Envicool has not lost its track position, but it has begun losing the market's illusion that high growth automatically equals high profit and high cash flow.

Longitudinal Financial Review

Financially, Envicool's past five years tell a complete story: revenue rose all the way, profit also rose but with a lag, and cash flow briefly improved in 2023 before working capital restrained it again in 2024-2025. From 2021 to 2025, revenue grew from RMB 2.228 billion to RMB 6.068 billion, and net profit attributable to shareholders grew from RMB 205 million to RMB 522 million. But net operating cash flow moved only from RMB 180 million to RMB 157 million, and the five-year cumulative operating cash flow to net profit attributable to shareholders ratio was about 0.66. Operating cash flow fell 55.89% year over year in 2024 and declined further to RMB 157 million in 2025.

Data source: company 2023, 2024, and 2025 annual-report summaries and full 2025 annual report.

The key signal in this table is how growth was generated, not whether the company grew. At the end of 2025, accounts receivable were RMB 3.054 billion, 39.42% of total assets; contract assets were RMB 229 million, up year over year; inventory was RMB 983 million; short-term borrowings increased to RMB 736 million, long-term borrowings were RMB 321 million, and non-current liabilities due within one year were RMB 247 million. Management itself explained in the annual report that the large gap between operating cash flow and net profit came from increases in operating receivables and inventory. Credit impairment losses of RMB 93.62 million and asset impairment losses of RMB 73.18 million were also mainly related to receivable bad debts, goodwill impairment, and inventory write-downs. For an equipment company with a strong project-based profile and long acceptance cycles, this is not abnormal, but it directly lowers the valuation ceiling investors can accept.

The gross-margin side is also sending mixed signals. In 2025, room thermal-control gross margin was 28.36%, up 1.39 percentage points from the prior year. Cabinet thermal-control gross margin was 27.24%, down 4.24 percentage points from the prior year. Based on 2025 main-business revenue and operating cost, overall gross margin was about 27.9%, slightly lower than about 28.7% in 2024. Selling, administrative, and R&D expenses were RMB 254 million, RMB 244 million, and RMB 446 million, respectively. R&D expenses rose 27.51% year over year, but finance expense shifted from RMB -0.8488 million in 2024 to RMB 16.1822 million, which the annual report explicitly attributed to lower FX gains and higher interest expense. In other words, Envicool is still investing, and it must invest. But the result of that investment has not yet appeared as a sustained lift in the margin center.

Share-Price and Valuation History

For a long time after listing, Envicool was only a niche equipment growth stock. The real valuation distortion happened from 2025 to the first half of 2026. Media reviews show that the share price rose from a stage low of RMB 21.51 on April 21, 2025, to an intraday high of RMB 121.74 on April 20, 2026, with market cap peaking at about RMB 118.3 billion. Immediately after the Q1 report, the market's concern over profit realization erupted and the share price quickly pulled back. Looking back today, the core driver of that rally was three layers of valuation expansion, rather than profit: the liquid-cooling penetration story, NVIDIA ecosystem mapping, and overseas AIDC imagination. The decline was triggered by one reverse realization: revenue growth does not automatically lead to profit and cash flow.

As of 2026-06-12, Envicool's share price was RMB 66.08 and total market cap was RMB 84.209 billion. Based on 2025 net profit attributable to shareholders of RMB 522 million, the static P/E was about 161x; based on 2025 revenue of RMB 6.068 billion, the P/S was about 13.9x. If 2025 operating cash flow of RMB 157 million is reduced by capex of RMB 303 million, free cash flow was negative. This valuation already requires sustained high-growth delivery and preferably quick cash-flow improvement. It is beyond the category of an ordinary manufacturing growth stock. The share price has not returned to the bubble peak, but valuation discipline is already tight.

Business Model and Industry Cycle

Revenue Structure, Cost Structure, and Operating Leverage

Envicool's revenue structure today looks dispersed, but the main line is clear: everything revolves around thermal control for high-heat-density equipment and scenarios. In 2025, energy-saving room thermal-control products generated RMB 3.448 billion, 56.83% of revenue; energy-saving cabinet thermal-control products generated RMB 1.977 billion, 32.59%; bus air conditioning plus rail-transit train air conditioning and services together accounted for only 2.23%; and "others" accounted for 8.35%. Externally, the company no longer emphasizes that it is only an equipment-room air-conditioning manufacturer. It includes data centers and intelligent-computing centers, compute equipment, electrochemical energy-storage systems, communications networks, power grids, electric-vehicle charging piles, industrial automation, and power conversion in its application scope. The benefit of this structure is that the cycle is not fully concentrated in one industry. The drawback is that profit quality can be dragged down by the most project-based, lowest-margin, slowest-acceptance segment among several business lines.

From a cost breakdown, Envicool remains a manufacturing business with heavy engineering delivery. In 2025 main-business cost, direct materials accounted for 80.48%, engineering installation fees 6.87%, after-sales service fees 3.17%, direct labor 3.83%, manufacturing overhead 3.85%, and freight 1.80%. This shows that although the company can talk about the liquid-cooling chain and system solutions, its commercial essence still cannot escape materials, manufacturing, installation, and service. Scale expansion will bring some operating leverage, especially as already reflected in higher-value room thermal-control products. But unlike pure software or pure chips, its margin uplift is naturally unlikely to be especially steep. When revenue falls, R&D, service networks, and project teams are also hard to compress quickly.

Cash generation has therefore become the most important layer to penetrate. In 2025, operating cash flow was only RMB 157 million, while cash paid to acquire fixed assets, intangible assets, and other long-term assets was RMB 303 million, implying apparent free cash flow of RMB -146 million. The annual report also discloses that the increase in construction in progress was mainly related to investment in the Central China headquarters base, while the increase in fixed assets related to equipment procurement and transfer of the South China headquarters base into fixed assets. This means a meaningful portion of 2025 capex was indeed expansionary and should not all be treated as maintenance capex. But even under a relatively lenient approach, treating only 40% as maintenance capex, 2025 owner earnings would be only about RMB 36 million, implying an owner-earnings yield of about 0.4% on the current market cap. The headline looks like a 160x P/E. Once translated into cash-flow terms, it becomes more expensive, not cheaper.

Moat and Governance

Envicool's real moat lies in three specific things, not in the three words "liquid cooling" by themselves.

First is cross-scenario engineering capability. The company sells quick-disconnect connectors, Manifolds, cold plates, liquid-cooling fluids, leak detection, CDUs, cabinets, room-level thermal control, and system integration as one connected offering, rather than only making a single cold-plate component. The 2024 annual report also discloses that as the first partner in Intel China's Data Center Liquid Cooling Innovation Acceleration Program, Envicool's BHS-AP platform cold plate, UQD04 quick connector, manifold, and rack-mounted liquid-cooling CDU passed Intel testing and validation, making it the first cold-plate liquid-cooling solution integrator for the Xeon 6 platform. This capability is built through system understanding, project experience, and supporting delivery, not by stacking one or two components.

Second is the customer entry threshold. The end users or project users named in the 2025 annual report include ByteDance, Tencent, Alibaba, Chindata, GDS, DataPort, China Mobile, and China Telecom. Top 5 customers accounted for 19.41% of sales, and Top 5 suppliers accounted for 15.18% of purchases. This shows that the company is neither overly dependent on a single customer nor controlled by a single supplier. More important, these customers generally have long validation cycles, strong reliability requirements, and heavy delivery-record requirements. A new entrant cannot replace an incumbent simply by being 5% cheaper.

Third is management's industry DNA. The founder and multiple executives have long backgrounds in Huawei Electric, Emerson, Liebert, Midea, and other environmental-control and network-energy systems. This makes the company naturally more like an equipment-engineering company in product roadmap, customer communication, and delivery system, with less concept-only volatility. The 2025 annual report shows the actual controller Qi Yong still serves as both chairman and general manager. The advantage is a short chain and fast execution; the problem is that governance depends heavily on a core individual. The 2025 annual report had no modified audit opinion, and the independent-director report did not disclose related-party transactions that should have been disclosed. That makes the governance baseline broadly reliable, but it does not mean there is a high governance premium. It looks more like a typical founder-controlled manufacturing listed company.

The moat praised by the market also requires two reminders. One is that liquid-cooling components themselves tend toward standardization, and cold plates, connectors, and distributors will keep attracting more suppliers. The other is that being full-chain does not automatically mean higher profit. Sometimes it simply means the company bears more system-integration and delivery responsibility. Envicool's advantages are real, but this is not a rent-collecting moat. It is more like a moat that requires continuous R&D, continuous project execution, and continuous delivery records to win the next order.

Industry Structure, Cyclicality, and Geopolitical Risk

The reason liquid cooling has suddenly become a capital-market hotspot in the past two years is the thermal design power of compute equipment. CAICT research shows that China's liquid-cooled server market reached USD 2.37 billion in 2024, with the vast majority using cold-plate liquid cooling. ODCC discloses that China's intelligent-computing-center liquid-cooling market was about RMB 18.4 billion in 2024, up 66.1% year over year, and is expected to reach about RMB 130 billion by 2029. The industry is still in its growth phase, not maturity. The profit pool is currently distributed mainly across three ends: upstream high-performance chips and core components, midstream servers and liquid-cooling system integration, and downstream cloud vendors, carriers, and large IDCs with hyperscale capex capacity. Envicool sits between components and system solutions. It can benefit from rising penetration, while also facing centralized procurement by large customers and capacity expansion by peers.

Its cyclical profile is an overlay of four cycles, not a single line. The first is the AI capex cycle, where the core variables are GPU installations, cabinet power density, and hyperscale campus construction. The second is the data-center construction and acceptance cycle, which directly affects revenue recognition and receivables collection. The third is the energy-storage and broader industrial thermal-control cycle, which determines cabinet thermal-control demand. The fourth is the technology iteration cycle, with cold plate, immersion, coolant routes, and liquid-cooling standards still evolving. Uptime Institute's view is important: AI is adopting direct liquid cooling faster, but enterprise IT deployment is slower because facility teams and IT teams must rebuild interfaces, failure modes are unfamiliar, and standardization still takes time. In other words, the penetration direction is sound, but the pace will not be a straight line.

Geopolitical and regulatory risks are not life-or-death for Envicool, but they will affect valuation. In the GB200 NVL72 design, NVIDIA raised rack-level liquid-cooling capacity to 120 kW and included more than 40 infrastructure partners, including Envicool, in its ecosystem. That gives Envicool strong market endorsement. On the other side, overseas AIDC business means longer delivery chains, more complex local certification, higher FX volatility, and more demanding financing management. The company also set up Thailand and Indonesia entities in 2025, showing overseas expansion is genuinely advancing. When Q1 profit dropped sharply, the first reason management named was FX losses and higher interest expense. That is enough to show that overseas expansion brings financial volatility into the statements, not just a valuation premium.

Horizontal Competitor Analysis

Competitive Landscape and Peer Profiles

Envicool faces a typical "different species on the same map" situation, rather than a lack of comparables. The most direct comparables must be divided into four categories. Vertiv is the global leader in data-center power and thermal management, with the strongest capabilities, a higher service mix, and a role as a collaborator in NVIDIA Blackwell reference architecture. Delta Electronics is a platform giant selling power, thermal management, UPS, and automation together, with liquid cooling only one high-growth branch on a huge business tree. Shenling Environmental is closer to a domestic special-purpose air-conditioning and environmental system-integration player, deeply focused on data-service industrial environments and industrial-process environments. Goaland is more component- and professional thermal-management-equipment oriented, with positions in power electronics and liquid-cooling links but still some distance from full-chain system delivery. Envicool's real niche is as a Chinese local, system-leaning middle-layer player that is closer to the compute liquid-cooling chain than traditional air-conditioning companies.

Vertiv has become a global infrastructure company. Its 2025 net sales were USD 10.230 billion, operating profit was USD 1.830 billion, ER&D spending was USD 442 million, and it had more than 5,000 global field service engineers. It sells packaged infrastructure across power, thermal management, controls, and services, not just cooling. For customers, Vertiv wins through service networks, global delivery, and system-level optimization. Its valuation is not low, but it also does not need imagination to support it like a pure theme stock. Compared with Vertiv, Envicool's engineering understanding is not much weaker in localized scenarios, but its global service capability, brand recognition, and cross-region delivery system still lag clearly.

Delta Electronics has become a platform. Its 2025 consolidated revenue was TWD 554.9 billion, after-tax net profit was TWD 60.1 billion, and ROE was 24.1%. By June 2026, the company had also launched prefabricated AI modular data-center solutions at COMPUTEX. This company does not need a single liquid-cooling story to prove itself because it has growth entries across power, thermal management, automation, buildings, and infrastructure. Customers often choose Delta because it can turn power and thermal management into an integrated platform, rather than for a single liquid-cooling component. For Envicool, Delta is not the most direct front-line price-war opponent, but it is the most important valuation-ceiling reference. If platform giants do not trade at extreme valuations, whether the market will keep giving a single-track company a higher premium is an open question.

Shenling Environmental is more like Envicool's domestic environmental-system neighbor. Its 2024 annual report positioned it as a professional special-purpose air-conditioning and integrated-solutions provider for data-service industrial environments, industrial-process R&D and production environments, professional special applications, and indoor public-building environments. Its 2025 net profit attributable to shareholders was about RMB 217 million, up 87.59% from the previous year, with total market cap about RMB 37.08 billion and a P/E close to 194x. Why would customers choose Shenling? Because it has deep experience in special-environment system integration and suits complex scenarios. Why might they also turn to Envicool? Because in the compute liquid-cooling chain, Envicool is more deeply coupled with servers and compute equipment, and the capital market is more willing to classify it as AI liquid cooling rather than special-purpose air conditioning.

Goaland has a different profile. The company is more focused on professional thermal-management equipment and liquid-cooling subsegments. Its 2025 net profit attributable to shareholders was about RMB 55.78 million, up 194.43% year over year. Its 2025 interim report disclosed that the company uses a direct-sales model of long-term technical cooperation plus brand demonstration, with customers mainly large state-owned enterprises in the power industry, listed companies, and leading internet companies. Goaland's strength is depth in professional links; its weakness is scale and platform capability. It represents the type of rival Envicool most needs to watch: not necessarily comprehensive, but able to use more aggressive pricing or speed to take orders in a specific liquid-cooling segment.

Quantitative Comparison

Translation exchange rates use 2026-06-12. † Calculated from market cap and 2025 annual-report metrics.

The most striking point in this table is who deserves to be more expensive and why, rather than who is more expensive. Vertiv is much larger than Envicool, deeper in globalization, and thicker in service network, yet its P/E is only about half Envicool's. Delta Electronics is a platform giant, with AI data centers only one part of the business, and it also has not received a much higher valuation than Envicool. Conversely, A-share comparables such as Shenling Environmental and Goaland are also in high-valuation territory, showing that the overall A-share liquid-cooling and environmental-control track carries a thematic premium. Peers being expensive does not make Envicool cheap. The more meaningful conclusion is that Envicool has a strong position in Chinese local full-chain liquid cooling, but when placed against global infrastructure and platform thermal-management players, its valuation is no longer conservative.

Current Fundamentals, Valuation, Risks, and Catalysts

What Is Happening Now

Looking only at the 2025 annual report, Envicool remains on an upward path. Revenue was RMB 6.068 billion in 2025, up 32.23% year over year; net profit attributable to shareholders was RMB 522 million, up 15.30%; non-recurring-adjusted net profit attributable to shareholders was about RMB 504 million, up 17.22%. Room thermal-control revenue was RMB 3.449 billion, 56.83% of total revenue, up 41.28%; cabinet thermal-control revenue was RMB 1.977 billion, 32.59% of total revenue, up 15.30%; overseas revenue was RMB 849 million, up 52.64%. In earnings communication, management explicitly attributed 2025 performance to promotion of full-chain compute liquid cooling, overseas business expansion, global supply-chain platform construction, organizational optimization, and technological innovation.

If we cut back to the 2025 interim report, the structure becomes clearer. In the first half of 2025, revenue was RMB 2.573 billion, up 50.25% year over year; net profit attributable to shareholders was RMB 216 million, up 17.54%; and net operating cash flow was RMB -234 million. Revenue broke out, profit rose with it, but cash flow had already sounded the first warning. By Q1 2026, revenue continued to rise 26.03% year over year to RMB 1.175 billion, but net profit attributable to shareholders fell to only RMB 8.6576 million, down 81.97%; adjusted net profit fell 87.10%; and net operating cash flow declined further to RMB -386 million.

Management's explanation for the Q1 profit decline was specific and typical of equipment-company bottlenecks. First, some overseas projects were settled in local currencies, so RMB appreciation caused FX losses, while expanded financing scale pushed up interest expense. Second, the pace of domestic IDC construction slowed, project implementation cycles lengthened, settlement and collection cycles became slower, and bad-debt provisions increased. Third, changes in the revenue mix caused gross margin to decline year over year. Fourth, orders were plentiful, but shipment and revenue recognition did not rise in sync. In other words, the real issue is that the chain converting demand into profit slowed at several links, rather than demand suddenly disappearing.

What the Market Is Trading and the Long-Short Split

The market's main narrative is still that high heat density in AI compute raises liquid-cooling penetration, and Envicool benefits from full-chain liquid cooling and overseas expansion. This narrative is not built on air. The company's cold plates, quick connectors, Manifolds, CDUs, and other liquid-cooling chain products have already been recognized by mainstream compute-chip vendors and leading equipment manufacturers. Intel testing validation and NVIDIA ecosystem coverage are also real. In H2 2025, management also clearly mentioned that overseas revenue in the room thermal-control business increased significantly, and that electronic thermal-dissipation growth was expected to accelerate in 2026.

Bulls truly believe three things. First, liquid-cooling penetration is far from over, and China's intelligent-computing-center liquid-cooling market in 2024 was only the starting point. Second, Envicool can keep climbing the value chain from room-level thermal control to rack-level and board-level liquid cooling. Third, overseas revenue growth of 52.64% shows it can benefit beyond the domestic market. Bears focus on three other things. First, revenue acceleration has not become profit acceleration: 2025 revenue grew 32.23%, while net profit grew only 15.30%. Second, cash flow is meaningfully weaker than profit: 2025 operating cash flow to net profit was only about 0.30. Third, receivables and impairments have begun telling investors that project-based conversion cannot be as smooth as an AI hardware theme. The core of the long-short disagreement is whether strong demand can become higher-quality profit and cash flow, not whether the demand is real.

Valuation Analysis

Start with cash-flow penetration. From 2021 to 2025, Envicool's cumulative net operating cash flow was about RMB 1.183 billion, cumulative net profit attributable to shareholders was about RMB 1.804 billion, and the five-year cumulative operating cash flow to net profit ratio was about 0.66. In the most recent two years, 2024 and 2025 were only 0.44 and 0.30. 2025 capex was RMB 303 million. Considering the headquarters-base construction, equipment deployment, and new fixed assets disclosed in the annual report, I judge that expansionary spending accounted for a high share of 2025 capex. But even if only 40% is treated as maintenance capex, 2025 owner earnings would be only around RMB 36 million, far below accounting profit of RMB 522 million. From this perspective, a headline P/E around 160x does not overstate valuation pressure. It understates the cash-conversion problem.

On relative valuation, Envicool currently sits in an awkward position: materially above the growth-discount speed of global leaders, while not more extreme than some A-share comparables' thematic premium. It is much more expensive than Vertiv and also more expensive than Delta Electronics. Compared with A-share peers such as Shenling Environmental and Goaland, it sits in the range of not the most expensive, but certainly not cheap. The problem is that high valuations among A-share peers may not be reliable in the first place. If the whole liquid-cooling and thermal-control track is near a historical high, investment discipline can no longer rely on peers also being expensive. It must return to absolute valuation.

The following table gives my three scenarios. They are price projections under the research framework, not investment advice. The valuation method mainly cross-checks 2027 earnings capacity and P/S, then applies a discount for cash-flow quality. I use a 2027 perspective instead of single-year 2026 profit because the company's near-term volatility is more affected by acceptance, delivery, FX, and expense disruptions. Using only 2026 profit would make the model too fragile.

Data basis: 2025 annual report, Q1 2026 report, current market cap and share price, with share count estimated backward from current total market cap.

After reviewing the margin of safety, the conclusion is direct. The current price is a clear premium to the implied value in the conservative scenario, leaving zero margin of safety. If the weakest assumptions in the base scenario, improved receivable collection and no further rise in bad debts, are cut by 30%, base valuation quickly falls to the high RMB 20s to low RMB 30s. If profit is flat over the next three years, the earnings yield at the current price is only about 0.62%, clearly below the China 10-year government-bond yield of about 1.74% on 2026-06-12. This is a classic good company at a bad price. My margin-of-safety conclusion is: none.

Risks, Catalysts, and Tracking Metrics

I think there are only five risks that most deserve attention.

The first is collection and bad-debt risk, with medium probability and high impact. Accounts receivable were RMB 3.054 billion at the end of 2025, 39.42% of total assets. In Q1 2026, management also explicitly said the slower domestic IDC construction pace lengthened settlement and collection cycles. This is the first transmission chain pressuring both profit and cash flow. If accounts receivable and contract assets continue to underperform revenue growth for two consecutive quarters, bad-debt provisions may rise further, and the market may reprice the company from a growth stock into a project-based company with heavy working-capital occupation.

The second is gross-margin and product-mix risk, with medium probability and high impact. In 2025, room thermal-control gross margin rose, but cabinet thermal-control gross margin fell 4.24 percentage points. In Q1 2026, the company again cited revenue-mix changes as the reason for a year-over-year gross-margin decline. The liquid-cooling story is large, but actual profit depends on how much high-value chain product is in revenue. If competition in cabinet thermal control and energy-storage thermal management continues to intensify, Envicool will first look like revenue is still fine while margins begin falling.

The third is FX and financing-cost risk, with medium probability and medium-high impact. Finance expense turned from negative to positive in 2025, and in Q1 2026 management again listed FX losses and interest expense as the first reason for the profit decline. Overseas expansion can open valuation room, but it also brings RMB exchange rates, overseas settlement, and financing costs into the income statement. For a company with a very high current valuation, this type of seemingly financial noise can also trigger sharp share-price volatility.

The fourth is sector valuation-center decline risk, with medium-high probability and high impact. Envicool currently trades at about 161x static P/E, and peers Shenling and Goaland are also expensive. This means the market is applying a high-discounted-growth logic to the entire liquid-cooling track. Once AI infrastructure investment growth normalizes, or market style shifts from high-beta themes back to earnings realization, valuation compression may occur before fundamentals change. The share-price reaction after the April 2026 Q1 report already provided a sample.

The fifth is governance and execution-complexity risk, with low-to-medium probability and medium impact. The actual controller serves as both chairman and general manager. Capacity expansion, overseas expansion, new liquid-cooling businesses, and global supply-chain platform construction are all advancing at the same time, and organizational complexity is rising quickly. The company currently has no obvious governance red flags, no modified audit opinion, and no disclosed major related-party transaction issue. But for this type of founder-controlled manufacturing company, the biggest risk is loss of execution rhythm, rather than the wrong strategic direction. Orders, delivery, working-capital occupation, and expense growth can run together, squeezing profit in the middle.

At the tracking level, I suggest focusing only on the following hard indicators:

Data basis: 2025 annual report, Q1 2026 report, current share price and market cap, and government-bond yield.

Among these indicators, the three most important items are plain ones, not another large order: whether bad-debt provisions can stop rising, whether receivables can stop growing faster than revenue, and whether operating cash flow can truly return close to profit. Liquid-cooling penetration is the long-term view. Cash flow is reality. Stocks are ultimately priced by reality.

Cross-Sectional and Longitudinal Synthesis

Longitudinally, Envicool has proven a capability that is very Chinese-manufacturing in character and also valuable: it can turn complex environmental-control problems into deliverable products, then turn deliverable products into a cross-scenario platform. From communications cabinets, equipment-room air conditioning, and bus air conditioning to rail-transit air conditioning, energy-storage thermal control, and data-center liquid cooling, it has not always stood on the most glamorous track, but it has consistently stood within the broad trend of thermal management becoming more important. Its past success did not rely on financial leverage or pure luck. The core was management's industry experience in network energy and precision cooling, understanding of customer scenarios, and willingness to do the hard work of system integration and engineering implementation. Those success factors remain today and have become more important because of the high-heat-density trend in AI compute.

Horizontally, Envicool's most real advantage is its position in China's local liquid-cooling chain, not absolute scale or a global service network. It is deeper into the compute-equipment side than traditional special-purpose air-conditioning companies, more capable of system solutions than point-component companies, and more like a pure beneficiary than platform giants. It fills the niche of a local full-chain liquid-cooling system supplier. The problem lies exactly there. This niche is attractive enough to draw competition, and it is not a globally monopolistic niche, so valuation should not rise without limit. Over the past year, the market looked more like it was rewarding Envicool for choosing the right track, rather than for having already converted the track dividend steadily into cash returns.

My core judgment on the company can be compressed into one sentence: Envicool looks more like a company whose fundamentals are still strengthening, while the stock has already run too far ahead. The issue today is how many years of future growth the current price has already bought, not whether it has growth. The current valuation requires the company to complete four things over the next two to three years, and each has to be more than slightly better: liquid-cooling penetration must keep accelerating, overseas execution must avoid mistakes, margins must avoid compression from competition, and cash flow must repair quickly. If any one of these is realized more slowly, the share price will face a swing back in the valuation system itself, not a minor fluctuation.

The most important variable over the next 1 year is whether collection and acceptance rhythms can repair, especially domestic IDC project collection and overseas project settlement. The most important variable over the next 3 years is whether liquid-cooling chain products can move from validation obtained to a major revenue share. The most important variable over the next 5 years is whether Envicool can push itself from a Chinese thermal-control leader into an infrastructure supplier with genuine global service and system-delivery capability. The conditions that would make this company a better investment candidate are simple: lower price, better cash flow, and more stable margins. If gross margin steps down for two consecutive quarters, receivables continue to grow quickly, and overseas expansion does not convert into revenue and cash flow, the company needs to be reassessed.

Bull and Bear Cases

Bull case:

• Room thermal-control revenue grew 41.28% year over year in 2025, showing that demand related to compute and data centers has entered the statements in concrete form.

• The Coolinside full-chain liquid-cooling solution has been recognized by mainstream compute-chip vendors and leading equipment manufacturers, and Intel validation further raises the customer entry threshold.

• Overseas revenue grew 52.64% year over year in 2025, so overseas expansion is no longer just a PPT story.

• Top 5 customers accounted for only 19.41% of sales, indicating a diversified customer structure rather than a single large-customer bet.

• The industry remains in a growth phase, and China's intelligent-computing-center liquid-cooling market is still expanding, so the track ceiling has not closed.

Bear case:

• Revenue grew 32.23% in 2025, while net profit attributable to shareholders grew only 15.30%, so profit realization lagged revenue.

• Operating cash flow was only RMB 157 million in 2025, far below RMB 522 million in net profit, indicating weak cash-flow quality.

• Accounts receivable were RMB 3.054 billion at the end of 2025, 39.42% of total assets, so bad-debt and collection risks are rising.

• Q1 2026 revenue grew 26.03% year over year, while net profit attributable to shareholders fell 81.97%, showing extremely fragile short-term earnings elasticity.

• The current static P/E is about 161x, with an earnings yield below China's 10-year government-bond yield, leaving almost no margin of safety.

Pre-mortem

If this investment loses 50% three years from now, the most likely first script is that from H2 2026 to 2027, domestic IDC construction and acceptance continue to be slow, while overseas projects are signed in volume but revenue recognition and collection are both slower than expected. The company is forced to keep provisioning for bad debts, cabinet thermal-control price competition pressures gross margin, and net profit attributable to shareholders stays around RMB 600 million to RMB 700 million for a long period. The valuation the market is willing to give it contracts from above 100x today to around 45x, and the share price may return to the RMB 25-30 range. This script does not require demand to collapse. It only requires conversion to remain slow.

The second script is that after 2027, the liquid-cooling chain gradually moves toward more standardized component competition, with Vertiv, Delta Electronics, domestic system integrators, and specialized liquid-cooling vendors jointly squeezing the profit pool. Envicool's revenue still grows, but more of that growth comes from low-margin system delivery, gross margin falls to 24%-25%, and operating cash flow continues to lag net profit. By then, the market will reclassify it as a cyclical equipment stock in a strong-demand track rather than a high-quality growth stock. The valuation center may fall to 30-40x. Even if net profit is still growing, the share price could be cut in half.

Final Research Conclusion

Envicool is a well-positioned company. It stands at the point where data-center liquid-cooling penetration is rising, management has industry experience, the product chain has depth, the customer base has quality, and overseas expansion has begun to deliver substantive incremental growth. Within China's liquid-cooling value chain, the company does deserve to be viewed as one of the leaders. The problem is that the stock has moved too fast, not that the company is poor. The 2025 and Q1 2026 statements already make the facts clear enough: high revenue growth is real, slow profit realization is real, and weak cash flow is also real. The market previously preferred to look only at the first two realities. Now it has to include the third.

My conclusion therefore does not go to either extreme. This is neither a bad company to avoid immediately nor a good target that can be bought comfortably at this price. More precisely, it is a company worth long-term tracking and worth placing in the candidate pool during an industry upcycle, but it is not worth taking the dual risk of high valuation and low margin of safety at the current price in June 2026. My view would change under two conditions: either the price returns to a range that compensates sufficiently for cash-flow risk, or the company delivers several consecutive quarters of smoother collection, bad debts, gross margin, and overseas conversion, so that profit and cash flow genuinely catch up with the track narrative.

【Investment Rating】

• Rating: Watch

• One-line investment thesis: Liquid-cooling demand is visible, but neither cash flow nor valuation offers a margin of safety.

• 【Ideal/Fair Buy Price】24-30 CNY

• Basis: A discounted purchase range corresponding to 2027 earnings capacity and valuation under the conservative scenario, with an approximately 20% margin of safety reserved.

• Acceptable holding price: 31-45 CNY

• Is it worth waiting for a better price: Yes. More specific buy triggers would be a share price returning to the RMB 24-30 range, while accounts-receivable growth falls below revenue growth and operating cash flow clearly repairs. The opportunity cost of waiting is that one may miss a phase-driven rebound in the AI liquid-cooling theme.

• Target holding period: If buy conditions are met, mainly 3-5 years; currently more suitable for 6-12 months of observation.

• Expected annualized return: On a rough three-year view, about -26% per year in the conservative case, about -17% per year in the base case, and about -8% per year in the bull case.

• Maximum loss risk: If bad debts, gross margin, and valuation compression occur at the same time, the maximum loss over three years could reach 50%-60%.

• Signals triggering reassessment: Operating cash flow remains negative for two consecutive quarters while accounts receivable continue to grow faster than revenue; overall gross margin declines for two consecutive quarters; overseas revenue growth turns negative while finance expense ratio rises materially; liquid-cooling chain certification and leading-customer expansion stall; the overall industry valuation center moves down materially.

Research Uncertainties

• The company does not separately disclose revenue, gross margin, and order metrics for electronic thermal dissipation / the liquid-cooling chain. I can only infer progress from room thermal control, management communication, and customer certification information, making it difficult to estimate value per GW precisely.

• Overseas customers and specific project names are disclosed only in limited detail. The market often directly links the company with the NVIDIA ecosystem, but public materials more clearly prove ecosystem inclusion and technical interfaces, not that large-scale revenue has already been secured.

• Share-count changes after the 2025 equity distribution mean current per-share valuation needs to be estimated backward from market cap, creating small calculation error.

• The liquid-cooling industry is still evolving quickly. Competition among cold plate, immersion, and coolant routes will change profit-pool allocation among suppliers, and the long-term valuation center is not stable.

• For some comparable companies, access to full original 2025 annual reports is not fully consistent, so a small amount of horizontal-comparison data relies on company investor pages or report summaries rather than full documents on the same basis.
