New Stock Spotlight | Sturgeon Aquaculture Technology in Hot IPO Subscription: World's Top Caviar Seller, an 'Underwater Business' on Par with Moutai

The Hong Kong IPO market is expected to perform strongly overall in 2026, with tech stocks—particularly those in the AI supply chain—standing out significantly. However, amid a wave of AI-related tech companies going public,a notably promising consumer stock—$XUNLONG SCITECH (06715.HK)$ is also now in hot IPO subscription.

Industry Positioning and Core Business

The global caviar industry chain consists of three segments:Upstream (sturgeon breeding and farming) → Midstream (processing and quality control) → Downstream (branding, sales, and distribution channels)

Sturgeon Aquaculture Technology is one of the very few companies globally that has achieved full vertical integration across all three segments.It breeds its own fingerlings, raises sturgeons itself (a 7–15 year cycle), processes them into caviar, and handles exports directly—some products are sold under its own brand 'Kaluga Queen' straight to end consumers, while the rest are produced as private-label goods for overseas premium food brands (such as fine food companies and airline catering suppliers in Europe and North America). The core value of this model lies in the scarcity of its cost structure: sturgeon breeding to maturity takes 7–15 years, requiring continuous investment in feed, labor, and land throughout that period, placing it beyond the reach of most small and medium-sized enterprises due to high capital and technical barriers.After 20 years of sustained capital investment, Sturgeon Aquaculture Technology now owns over 1.4 million mature female sturgeons—a genuine time-based barrier for any new entrant.

Kaluga Queen operates two key business segments:

Caviar Business: Caviar is the company's core business by far,with a gross margin consistently maintained between 70% and 75% over the past three years—a level far exceeding that of typical food companies and placing it among the top tier in the consumer goods industry.Russian sturgeon caviar represents the company’s single largest concentration of risk, accounting for more than half of total revenue. Hybrid sturgeon caviar is a growth category, as China is currently the sole global producer,and the absence of overseas supply competition enhances its pricing power.

Sturgeon products and others:including sturgeon meat products and live fish sales, which are by-products of sturgeon farming. These carry significantly lower gross margins compared to caviar and hold a subordinate strategic position—they essentially serve as a means to utilize male sturgeons (which do not produce roe and thus have much lower value per unit) and deceased or substandard fish.

Kaluga Queen's business model can be summarized by a simple chain: large-scale farming reduces unit costs → high-margin caviar operations sustain overall profitability → sales of sturgeon meat and live fish absorb low-value male fish and by-products.

These three elements are tightly interlinked, maximizing the commercial return from every mature female sturgeon raised over many years.The larger the scale, the lower the marginal cost per unit (‘the additional cost of raising one more fish keeps decreasing’), which underpins the caviar business’s ability to maintain a gross margin above 70%.

Competitive landscape: The market leader is four times ahead, yet overall market concentration remains low.

The global caviar market is in a state of ‘supply shortage relative to demand’—The long sturgeon farming cycle constrains the pace of capacity expansion, leaving an annual global demand gap of nearly 900 metric tons.

Kaluga Queen is projected to hold a 36.1% market share in 2025, more than four times that of the second-largest player.Although European family-owned businesses benefit from brand heritage, their capacity expansion is severely limited by high cold-water farming costs and small-scale family-run operations.

Why is Kaluga Queen’s IPO worth watching?

Scarcity value: The only caviar-focused stock listed on the Hong Kong Stock Exchange, serving as a gateway for global investors.

There is currently no pure-play caviar stock comparable to this in the Hong Kong market, nor in the A-share market. The listing of Sturgeon Technology provides investors seeking exposure to the 'premium food' segment with the only secondary market entry point. The global caviar industry’s CR5 (combined market share of the top five companies) stands at just 56.7%, yet the market leader alone holds a 36% share—a structure featuring an absolute dominant player within a highly fragmented industry, which itself presents investment appeal.

Profitability: Steady net profit margin of 47% over three years, on par with Kweichow Moutai

The company has maintained a net profit margin above 47% for three consecutive years, reaching 58.3% in the first half of 2025—surpassing Kweichow Moutai’s 49.89% during the same period. This level ranks among the highest globally in the food industry.

More notably, after excluding fair value changes of biological assets, the company reported an adjusted net profit of RMB 401 million in 2025, translating into an adjusted net profit margin exceeding 52%. This demonstrates that the core business—comprising export sales and processing—generates genuine profitability, independent of accounting gains from valuation changes in live fish.

Additionally, the number of overseas customers increased from 108 in 2024 to 129 in 2025, indicating continued expansion of its international sales network and providing visible fundamental support for revenue growth over the next one to two years.

Growth potential: Per capita caviar consumption in China is only 1/15th of that in Europe and the U.S.

Sturgeon Technology’s current domestic revenue amounts to only RMB 125 million (16.2% of total revenue), leaving the Chinese market virtually untapped.

The company’s announced plan to open approximately 50 offline flagship stores within five years, coupled with its extensive social media marketing initiatives, signals a strategic shift from B2B (restaurants and hotels) toward B2C (individual consumers). Should domestic consumption see meaningful breakthroughs, the current revenue model—predominantly based on contract manufacturing—would be reshaped. Sales under its own brand carry significantly higher gross margins than contract manufacturing, implying greater earnings elasticity.
