Sige New Energy Passes HKEX Listing Hearing; Single Product Accounts for Over 90% of Revenue

ZC Asia has learnt that Sige New Energy (Shanghai) Co., Ltd. (hereinafter referred to as “Sige New Energy”), which was established just four years ago and is regarded as a “Huawei-affiliated” start-up, has recently passed the Hong Kong Stock Exchange’s listing hearing. Should the listing be successful, it will become the first publicly listed company in the global stackable distributed photovoltaic-storage integrated system sector.

Explosive Growth in Performance: From Losses to Annual Profits of 2.9 Billion

Financial data shows that the company’s revenue surged from 58 million yuan in 2023 to 9.001 billion yuan in 2025, representing a growth of over 150-fold within two years. In terms of profitability, the company recorded a loss of 373 million yuan in 2023, achieved a net profit of 84 million yuan in 2024, and saw net profit rise further to 2.919 billion yuan in 2025.

The company’s gross profit margin improved from 31.3% in 2023 to 50.1% in 2025. This shift is primarily attributable to the market performance of its flagship product, the “SigenStor” five-in-one photovoltaic-storage-charging integrated unit. Featuring a modular, stackable design, this product integrates a photovoltaic inverter, energy storage converter, battery and energy management system, and DC charging module, meeting the overseas residential market’s demand for flexible deployment and intelligent management. According to a Frost & Sullivan report, Sigen New Energy became the global leader in this segment by shipment volume in 2024, with a market share of 28.6%. The company’s emphasis on “AI + energy storage” technology forms the core rationale for its valuation.

“Huawei-affiliated” heritage and capital-driven expansion

The company’s founder, Xu Yingtong, worked at Huawei for nearly 23 years, serving as President of Huawei’s Smart PV Business. Several members of the core team also have a Huawei background, which has laid the foundation for Sige New Energy in product definition, global channel expansion and supply chain management.

On the capital side, Hillhouse Capital holds a 14.89% stake in the company, with institutions such as Guangzhou Huaxin Shengjing also deeply involved. Since its establishment in 2022, Sige New Energy has completed multiple rounds of financing, with its valuation rising rapidly. This Hong Kong IPO serves both as validation of its growth narrative and as a means to raise funds for the next phase of capacity and market expansion.

On 13 March 2026, the Smart Energy Centre in Nantong, Jiangsu, was officially inaugurated. With a total investment of 500 million yuan, it boasts an annual production capacity exceeding 300,000 inverters and energy storage packs. This provides the physical infrastructure for the company’s expansion into the commercial and industrial energy storage and ground-mounted power station sectors.

Global Expansion and Regional Concentration Risks

To date, Sige New Energy’s operations span 85 countries and regions worldwide, with partnerships established with 172 distributors. In terms of revenue structure, Australia is its largest market, accounting for 42.6% of revenue in 2025. Europe and Africa are key growth drivers, with the African market recently securing contracts for projects exceeding 1 GWh.

High reliance on a single national market entails certain policy and exchange rate risks. The penetration rate of residential solar-plus-storage systems in Australia is already among the highest globally, leaving limited room for market growth. Furthermore, changes in local regulatory policies, grid connection rules and consumer subsidies could all impact the company’s performance.

Furthermore, the company has recently expanded from residential energy storage into the commercial, industrial and large-scale utility-scale solar power sectors, launching high-power string inverters. This shift means it will face direct competition from established players such as Sungrow. Utility-scale projects involve long project cycles, slow cash flow recovery and different channel requirements, posing new challenges to Sigen New Energy’s organisational capabilities and capital efficiency.

Despite its rapid growth, the potential risks facing Sigen New Energy are equally worthy of attention.

In terms of product mix, the SigenStor series accounts for over 90% of the company’s revenue. Whilst this reliance on a single product is an advantage during periods of rapid growth, it leaves the company with little room for manoeuvre should technological shifts occur, competitors make breakthroughs, or quality issues arise.

Regarding quality, in November 2025, Sigen New Energy proactively recalled certain products in Australia due to a risk of overheating in the AC power plugs used in some inverters. Whilst the recall itself demonstrates a sense of responsibility for quality control, it also exposes the pressures on supply chain and quality management arising from rapid expansion. For energy storage equipment where ‘safety’ is a core selling point, quality incidents could have a long-term impact on brand reputation.

In terms of the competitive landscape, competition in the global distributed solar-plus-storage market is intensifying. Competitors such as Tesla’s Powerwall, Huawei, Sungrow and GoodWe are all accelerating product iteration and expanding into lower-tier markets. It remains to be seen whether Sige New Energy can continue to expand its market share whilst maintaining high gross margins.

Furthermore, the company has undergone numerous early-stage financing rounds, resulting in a significant proportion of shares held by institutional investors. Should the share price perform below expectations following the IPO, or once the lock-up period expires, the company may face some selling pressure.
