RelyEZ Files Again for a Hong Kong IPO as Storage Economics Tighten

RelyEZ Energy Storage has reportedly filed again for a Hong Kong IPO, one month after its first application expired without producing a listing. The Shenzhen company submitted the new application on August 9, according to a 36Kr report, with CMB International acting as sole sponsor.

That action sounds procedural, but it creates a sharper test for the company. RelyEZ must persuade investors that its rapid revenue growth represents durable demand, not temporary volume gained through lower prices and concentrated contracts.

The filing also arrives amid a crowded migration toward Hong Kong. Battery manufacturers, system integrators, and energy technology suppliers are seeking international capital as they expand beyond China.

Successful listings from CATL and Sigenergy have demonstrated investor demand. They have also raised the standard for smaller applicants. RelyEZ enters that contest without their scale, established public-market history, or equally broad customer base.

The core question is therefore not whether grid storage demand is rising. It is whether RelyEZ can convert that demand into cash, repeat orders, and defensible margins while much larger suppliers chase the same projects.

The Second Filing Restarts the Clock, Not the IPO

RelyEZ has returned to the listing queue, but a renewed application does not mean that Hong Kong has approved an offering.

RelyEZ first submitted an application for a Main Board listing on January 9, 2026. That application identified CMB International as the sole sponsor and introduced the company under its English name, RelyEZ Energy Storage Technology.

The original application proof was published through the HKEX filing system. It warned that the application had not been approved and that the exchange could accept, return, or reject it.

Hong Kong application proofs normally remain active for six months. The January application consequently expired on July 9 without a completed offering.

The reported August 9 submission effectively renews the process. It gives regulators and potential investors a refreshed document, while allowing the company to update financial information and material developments.

It does not establish an offering size, valuation, share allocation, or trading date. Those details generally remain redacted until an applicant advances further and publishes a formal prospectus.

This distinction matters because “filing for an IPO” often gets interpreted as “going public.” The two events sit far apart in Hong Kong’s listing process.

The exchange must review the applicant’s disclosures and eligibility. The company must answer regulatory questions, pass a listing hearing, register its final documents, market the offering, and secure sufficient investor demand.

Any of those stages can delay a transaction. Market volatility can also persuade an applicant and its sponsor to wait, even after regulatory progress.

RelyEZ has disclosed a business built around integrated energy storage system solutions and related equipment. An energy storage system combines batteries, thermal controls, power electronics, safety components, and software into deployable infrastructure.

Its customers include project owners, engineering contractors, and subcontractors. These buyers use storage systems to move electricity across time, stabilize renewable generation, and provide grid services.

The company was established in 2019 and converted into a joint-stock company in December 2025, shortly before its first application. That restructuring prepared it to issue shares under the proposed Hong Kong listing.

RelyEZ says its market position extends beyond equipment sales. It describes its model as covering an energy storage asset’s lifecycle, including system design, integration, delivery, and operational support.

That broader description supports a more valuable story than simple hardware manufacturing. Investors must still determine how much recurring or defensible value the lifecycle model actually produces.

The second filing therefore changes one concrete fact: RelyEZ remains committed to the Hong Kong route. Everything after that remains conditional.

The renewed application must eventually show whether operations advanced during the additional months. Updated revenue quality, cash collection, overseas delivery, and customer concentration will matter more than the filing date itself.

RelyEZ’s Growth Story Comes With a Cash-Flow Test

The company has demonstrated fast accounting growth, but investors will examine whether project revenue turns into collectible cash.

RelyEZ reported revenue of RMB435 million in 2023 and RMB1.14 billion in 2024, according to figures drawn from its first application. That represented annual growth of approximately 163 percent.

Net profit increased from RMB40.7 million to RMB96.3 million across those two years. Overall gross margin moved in the opposite direction, falling from 21.6 percent to 17.8 percent.

For the first nine months of 2025, the company recorded RMB881 million in revenue and RMB70.9 million in net profit. Gross margin recovered slightly to 18.3 percent.

Those figures describe a profitable company with substantial growth. They do not, by themselves, settle the quality of that growth.

Project-based energy businesses can recognize revenue well before every invoice becomes cash. Customers may pay through milestones tied to delivery, grid connection, testing, or acceptance.

That structure creates working-capital pressure. The supplier purchases cells and other equipment, pays manufacturing expenses, and delivers the system before collecting the full contract amount.

At the end of September 2025, RelyEZ reportedly carried RMB845 million in trade receivables, notes receivable, and contract assets. Together, those balances represented about 42 percent of total assets.

The company also recorded a net operating cash outflow of RMB40.9 million in 2024. A profitable income statement combined with negative operating cash flow deserves close attention.

It does not automatically signal weak contracts or impending losses. Rapidly expanding project suppliers often consume cash because receivables and inventories grow faster than customer payments.

However, the pattern shifts financing risk onto the company. RelyEZ must fund procurement and execution while waiting for customers to complete acceptance or settle invoices.

A Hong Kong offering would provide capital that can absorb this timing gap. That makes the listing commercially useful, but it also exposes the tension inside the investment case.

If revenue growth requires increasingly large working-capital commitments, outside financing supports growth without necessarily improving the underlying cash cycle. Investors will want evidence that collection efficiency improves as the company scales.

Customer concentration makes that question more urgent. Reports based on the application indicated that RelyEZ’s five largest customers generated 80.8 percent of revenue during the first nine months of 2025.

A concentrated customer base can create operational efficiency. Large utility projects require significant deliveries, and winning one contract can transform a supplier’s annual results.

The same concentration can make revenue uneven. A delayed project, disputed acceptance milestone, or slower customer payment can materially affect a reporting period.

RelyEZ’s 2024 results illustrate that seasonality. The company recorded a loss during the first nine months before recognizing a large portion of annual revenue in the fourth quarter.

That timing does not prove the underlying projects were weak. It shows why annual growth rates can conceal execution and collection volatility.

The renewed filing should provide a better view of what happened after September 2025. Investors need updated aging data for receivables, subsequent collections, contract liabilities, and operating cash flow.

They will also watch whether the company’s customer mix broadened. A growing number of customers would reduce dependence only if revenue becomes less concentrated and those customers pay on workable terms.

The quality of new overseas contracts matters as well. International projects can diversify revenue, but they can also extend delivery chains, introduce foreign-exchange exposure, and complicate legal enforcement.

For RelyEZ, faster growth strengthens the IPO story only when it produces a healthier balance between revenue, cash, and customer risk.

Why Storage Prices Complicate the RelyEZ Hong Kong IPO

Energy storage demand is expanding, while the price attached to each delivered unit faces persistent pressure.

RelyEZ sold 2.46 gigawatt-hours of storage capacity during the first nine months of 2025, according to a breakdown reported by EnergyTrend. Integrated solutions contributed 1.35 GWh, while product sales contributed approximately 1.12 GWh.

Integrated large-scale storage solutions produced RMB817 million in revenue during that period. They represented 92.7 percent of the company’s total revenue and generated an 18.3 percent gross margin.

Standalone energy storage product sales produced RMB52.5 million, or about 6 percent of revenue. Their gross margin had fallen to 5.4 percent.

That contrast explains why RelyEZ emphasizes solutions. Packaging hardware with design, integration, controls, commissioning, and service can preserve more value than selling standardized equipment alone.

Yet solution revenue does not escape industry pricing. Battery cells remain a major input, while customers compare bids using cost per watt-hour, expected availability, warranty protection, and lifetime performance.

RelyEZ’s disclosed average selling price for integrated solutions was RMB0.44 per watt-hour during the first nine months of 2025. Its storage products averaged RMB0.38 per watt-hour.

Reports based on the application said core product prices had declined sharply over two years. The company attributed lower pricing to cheaper battery cells, intense competition, and production efficiencies.

Cheaper cells benefit system suppliers because input costs fall. They also invite aggressive bidding because rivals can pass savings to customers and pursue market share.

The result is a familiar industrial squeeze. Shipment volume increases, reported capacity reaches new records, and revenue grows. At the same time, the economic value captured from each unit can narrow.

RelyEZ’s gross-margin pattern reflects that tradeoff. Its overall margin remained in the high teens, but the margin on product sales fell substantially.

The company’s strategic response is to move toward integrated projects and lifecycle services. That approach gives it more control over system architecture and customer relationships.

It also increases execution responsibility. A vendor supplying an integrated system becomes accountable for component compatibility, thermal management, commissioning, availability, and long-term performance.

Storage projects must operate safely across thousands of charge and discharge cycles. Failures can create warranty expenses, replacement obligations, schedule penalties, and reputational damage.

Grid-scale systems introduce additional complexity because their economics depend on local market rules. A project designed for frequency regulation has different operating requirements from one shifting solar output into evening demand.

Software and controls can improve those economics, but they do not eliminate commodity exposure. Most integrators still depend on external cell suppliers and face similar component cost curves.

RelyEZ reported 103 research and development employees at the end of September 2025, representing 35.3 percent of its workforce. Research spending was RMB19 million in 2023, RMB34.1 million in 2024, and RMB21.6 million during 2025’s first nine months.

R&D spending fell as a percentage of revenue, from 4.4 percent in 2023 to 2.5 percent during the latest reported period. The decline can reflect operating leverage, but it also raises questions about differentiation.

Investors will want to identify which capabilities RelyEZ owns and which it assembles from suppliers. Proprietary controls, safety systems, and service data can support margins. Standardized enclosures and purchased cells offer fewer barriers.

The company highlights projects including a 500 MW, 2,000 MWh installation in Inner Mongolia and deployments totaling 1.5 GWh in Yunnan. Those figures come from RelyEZ’s 2025 project summary.

Company announcements demonstrate project scope, not verified lifetime economics. Investors still need evidence covering commissioning, utilization, performance, and customer payment.

This is the central mechanism behind the filing. RelyEZ needs more capital to pursue larger projects, while larger projects create bigger procurement needs and potentially larger receivable balances.

An IPO can fund the cycle. Only disciplined pricing, project selection, and collections can make that cycle self-sustaining.

Hong Kong’s Battery Listings Raise the Competitive Bar

RelyEZ is entering a receptive market, but that market now offers investors several storage companies with different strengths.

Hong Kong became an important fundraising venue for Chinese battery companies after CATL completed its secondary listing in May 2025. The offering raised about HK$35.7 billion before any over-allotment option.

CATL shares rose strongly in their trading debut. The company’s scale, profitability, and global customer relationships helped attract demand despite geopolitical scrutiny.

CATL held nearly 38 percent of the global electric-vehicle battery market in 2024, according to listing information cited by the Associated Press. It also operates in stationary energy storage.

That scale changes investor expectations. RelyEZ is not competing with CATL solely for project orders. It is competing for attention and capital inside the same broad investment theme.

Sigenergy provided another reference point in April 2026. The energy storage company sought about HK$4.4 billion through its Hong Kong offering, with proceeds directed toward production, research, and global sales.

Sigenergy’s offering included 13.57 million shares priced at HK$324.20 each, according to its IPO terms. The company focused heavily on modular solar and storage products.

Other suppliers have joined the queue or announced listing plans. The group spans battery manufacturers, system integrators, power electronics companies, charging providers, and materials suppliers.

For investors, that pipeline creates choice. They can favor upstream battery scale, integrated systems, overseas exposure, stronger cash flow, or specialized technology.

For applicants, it creates comparison risk. A company with fast revenue growth can still receive a cautious valuation if competitors offer better margins, broader customers, or more predictable cash generation.

RelyEZ’s clearest point of distinction is its concentration on integrated storage solutions and asset-lifecycle support. It serves utility-scale and commercial applications rather than relying on one consumer product.

The company has also begun building an overseas pipeline. It started developing international business during the second half of 2024 and recorded RMB8.6 million from American customers during 2025’s first nine months.

That amount remained small compared with total revenue. However, RelyEZ said it had entered contracts or purchase orders involving customers across the United States, Japan, Hungary, Poland, Spain, Mexico, Kenya, and Burkina Faso.

Signed orders do not guarantee recognized revenue. Overseas projects must clear financing, permits, shipping, installation, testing, and grid-connection milestones.

International expansion can nevertheless strengthen the company’s case. It reduces dependence on China’s intensely competitive procurement market and places RelyEZ closer to regions adding renewable generation.

It can also make the model harder to manage. Different electrical standards, fire codes, warranty expectations, and grid rules require local engineering and service capacity.

Trade policy adds another layer. Governments increasingly link energy incentives and public procurement to supply-chain origin, domestic manufacturing, and security requirements.

Chinese storage suppliers can remain competitive in markets where cost and delivery dominate. They face greater friction where policy restricts components or creates local-content conditions.

Hong Kong offers access to international investors, but a listing cannot remove those commercial barriers. It can finance factories, sales teams, and compliance work needed to respond.

The market backdrop is supportive. Hong Kong raised nearly HK$300 billion across approximately 100 listings in 2025, according to figures summarized in a battery IPO analysis.

The same analysis said A+H listings generated about half of total proceeds. RelyEZ is different because it is not already listed on a mainland exchange.

That distinction cuts both ways. RelyEZ offers investors direct access to a younger storage specialist, but it lacks the reporting history associated with an established public company.

Its renewed application must therefore do more than ride sector momentum. It must explain why RelyEZ deserves capital before larger or more mature applicants absorb investor demand.

The Filing Still Leaves Three Signals to Watch

The next meaningful evidence will come from regulatory progress, cash conversion, and overseas project delivery.

The first signal is whether RelyEZ reaches a Hong Kong listing hearing. A renewed application can remain under review for months, and publication alone reveals little about regulatory readiness.

A successful hearing would indicate that the exchange has completed a substantial review of eligibility and disclosure. It would not guarantee strong demand or a completed transaction.

The filing’s document history also matters. Supplemental disclosures can reveal which topics required clarification, including customer concentration, receivables, safety exposure, or ownership arrangements.

The second signal is updated cash conversion. Revenue and profit growth will carry less weight if operating cash flow stays negative and receivables continue rising.

Investors should compare the growth of receivables with the growth of revenue. They should also examine aging categories, credit-loss provisions, subsequent settlement, and contract asset conversion.

Improvement would support RelyEZ’s claim that recent growth represents scalable execution. Deterioration would suggest that the company is financing customers or accepting slower payment to win volume.

The third signal is recognizable overseas revenue. Announced agreements and geographic coverage establish a pipeline, but completed projects show whether RelyEZ can operate outside its home market.

Overseas revenue should become material without producing a disproportionate increase in selling expenses, inventories, or working capital. New customers should also reduce concentration rather than simply replace one dominant account with another.

Safety and performance data belong inside this signal. Successful commissioning, stable availability, and manageable warranty costs would strengthen the company’s lifecycle-services narrative.

The absence of those results would not invalidate global expansion. It would leave the international strategy at an earlier and riskier stage than headline project announcements imply.

RelyEZ’s second filing ultimately asks investors to fund an industrial scaling process. The company purchases components, integrates complex systems, delivers capital projects, and waits for milestone payments.

That model can create significant value when project selection and cash collection remain disciplined. It can consume capital rapidly when pricing falls or customers delay acceptance.

Hong Kong’s active IPO market gives RelyEZ a credible route to financing. The storage boom gives it a large underlying opportunity. Neither removes the need to prove repeatable economics.

Readers following the RelyEZ Hong Kong IPO should therefore look beyond the eventual valuation. The better questions concern who pays, how quickly they pay, and what margin remains after the system operates.

The next version of the application should make those answers clearer. Until then, RelyEZ’s return to the queue represents continued ambition, not a completed market verdict.
