With strong cornerstone investors backing it, what makes Topu CNC the 'invisible chassis' of commercial aerospace?
In May 2026, the Hong Kong stock IPO market welcomed a special contender.
On its list of cornerstone investors appeared names like RBC, 3W, Boyu, HH Capital, UBS, CDH Partners, Cithara, Fullgoal, China Asset Management, Shanghai Minhang, TT International, Mirae Asset, GSAM Goldman Sachs, and others—a remarkable lineup of top-tier institutions for a single company.The company's market capitalization at issuance and issue size were only HKD 10.801 billion and HKD 1.724 billion respectively, making such a gathering of top-tier institutions quite unusual.。
Even more intriguing is that Royal Bank of Canada (RBC), a leading asset manager, rarely invests but typically holds onto landmark IPOs for the long term when it does. Meanwhile, TT International, an established British investment firm, made its debut as a cornerstone investor in Hong Kong stocks.
Against the backdrop of frequent new share price collapses in the Hong Kong stock market, these institutions known for their long-term vision and sharp acumen collectively placed their trust in a company specializing in five-axis CNC machine tools—a phenomenon worth pondering.
Their involvement suggests that Topper CNC’s story goes beyond just being another 'high-end manufacturing enterprise IPO.' A closer look reveals that to truly understand Topper CNC,one cannot bypass a certain company—SpaceX.。
This isn't about riding on SpaceX's popularity; rather, it raises an important proposition long overlooked by the capital markets: The real bottleneck in China’s commercial aerospace industry has never been design blueprints, but the capability to mass-produce rockets as industrial products. What Topper CNC sells isn’t just machinery—it’s essential infrastructure for this capability.
01
Equipment always plays a strategic role.
Over the past few years, the market narrative around commercial aerospace has revolved around engineering milestones such as 'maiden flights,' 'orbit insertion,' and 'recovery.'
In 2025, China completed 92 space launches, with 50 being commercial launches, accounting for more than half for the first time; 311 commercial satellites were placed into orbit, making up 84% of the total number of satellites launched. Entering 2026, out of the first 18 space launches in one and a half months, commercial launches accounted for 11, breaking through 60%, with 127 commercial satellites entering orbit, representing an even higher proportion of 91%. Many investors are very familiar with these figures.
But the key question is: after the rising number of launches, what changes will occur in the core contradictions of the industrial chain? The answer can be found in the development path of SpaceX.
Elon Musk himself has a widely circulated original quote: “Design is easy. Production is hard. Making one of something is easy, making a large number of something that is reliable and affordable is extremely hard.” The deeper meaning of this statement is: SpaceX's true moat is not the reusable rocket technology itself, butthe ability to mass-produce spacecraft as industrial products.。
At the beginning of 2026, SpaceX posted on LinkedIn that its Hawthorne factory had significantly expanded the production capacity of Starship components, recruiting positions covering CNC machinists, CMM programmers, precision inspectors, automation engineers, etc. For investors, the implied hiring spree in this post indicates that SpaceX is striving to industrialize the production of Starships rather than treating it as a low-rate R&D project.
Looking back at the domestic situation, the pain points of the industry are equally clear.
China’s two major constellations - 'State Grid' and 'Thousand Sails',plan to collectively launch 7,600 satellites by 2028.If calculated based on the current mainstream batch launch capability of 18-36 satellites per rocket, to complete the launch of 7,600 satellites by 2028, an annual average of 200 to 400 launches would be required. Every satellite and every rocket, from structural parts to engines, depends on high-precision processing.
This logic has been repeatedly verified across multiple industrial cycles.
Whether it was the energy revolution sparked by photovoltaics and new energy vehicles in the past, or the current rise of AI bringing about a major cycle in storage and optical communication, the upstream equipment manufacturers are often the first to benefit before the explosion of end-user applications.
Why? Because for any industry moving from 'laboratory' to 'industrialization,' the primary bottleneck is always manufacturing capability. While design solutions may be feasible, the key variable determining industrial progress is whether products can be produced stably, at low cost, and in large quantities.
Commercial aerospace is at such a turning point. SpaceX's Falcon 9 first-stage rocket can already be reused up to 24 times, but that is the result of precise equipment and stable processes, not luck. The daily production of Starlink terminals exceeds 20,000 units, which is due to deep control over the manufacturing process. SpaceX has even started developing its own RF chips because off-the-shelf solutions cannot meet its mass-production pace.
These facts collectively point to one conclusion:Mastering the 'equipment capable of producing high-end aerospace parts' means controlling the lifeline of the industry chain.
However, China faces unique challenges in this area. Five-axis CNC machine tools, especially those used in aerospace, have long been subject to foreign technological blockades. Even if they can be purchased, restrictive agreements must be signed, sometimes completely prohibiting their use in military or aerospace applications. According to the prospectus, the localization rate in this field will only reach about 54.6% by 2025.
This creates a 'scissors gap' between supply and demand: downstream demand is exploding, but upstream critical equipment relies on imports, which could be cut off at any time.
The capital expenditure direction of commercial rocket companies further clarifies the trend of industrial evolution. By the end of 2025, LandSpace's STAR Market IPO application was accepted, aiming to raise 7.5 billion yuan, of which 2.77 billion yuan is specifically earmarked for projects to enhance the production capacity of reusable rockets. Following closely, in March 2026, CAS Space’s STAR Market IPO application was also accepted, with plans to raise 4.18 billion yuan, over 80% of which will be invested in R&D projects and industrial base construction to lay the foundation for scaled production.
The fundraising plans of these two leading commercial rocket enterprises after their IPOs clearly indicate that industrial capital is shifting comprehensively from 'R&D narratives' to 'manufacturing narratives.' Equipment procurement and capacity building have become the core expenditures determining the competitive landscape of the next phase in commercial aerospace.

What positions Topper CNC in this space?
Although there are many domestic CNC machine tool companies, the reason why Topper CNC deserves individual attention lies in its core technology advantage, which is concentrated in the aerospace sector—a field with the highest manufacturing thresholds and the most stringent precision requirements.
Key components such as aircraft skins, dome sections of rocket fuel tanks, and blades of aero engines share common characteristics: thin, large, complex shapes, difficult-to-process materials, and extremely high precision requirements. These cannot be easily achieved using conventional three-axis machine tools. One of Topper CNC's core competencies is the 'dual five-axis mirror milling technology,' successfully developed in 2016, making China the third country globally to master this technology. Prior to this, this technology was an explicit no-go zone.
Based on the revenue from five-axis CNC machine tools in the aerospace sector in 2025,Topper CNC ranks first among all suppliers in China’s five-axis CNC machine tool industry, with a market share of 10.0%.
Another technological breakthrough is reflected in the 'carbon fiber composite material five-axis machine tool.' The moving parts of traditional machine tools are metallic, heavy, with high inertia and significant thermal deformation. Topper CNC implemented a bold technological innovation—replacing all moving parts with carbon fiber composite materials. It is precisely this innovative courage that has made it the world's first, and currently the only, machine tool manufacturer to achieve this. In the fiscal year 2025, the company sold six units in its first year, generating revenue of 24.4 million yuan.
This product has broad application scenarios, solving the issue of precision stability for large, complex structural components under high-speed operation—a technical bottleneck also faced in semiconductor equipment cavity processing and new energy vehicle integrated die-casting mold processing.
Thus, a clear logical chain emerges: the higher the technical threshold, the more manufacturing equipment needs to be independently controllable. These 'China-only' equipment capabilities ultimately serve national-level projects such as multi-series carrier rockets, the C919 large aircraft, and aerospace engines. According to the prospectus, Topper’s clients cover key processes such as aircraft skin milling, engine casing and turbine disk machining, and rocket fuel tank welding, spanning the entire cycle from design to mass production.
Looking at the revenue structure again,Total revenue for the fiscal year 2025 was 578 million yuan, with aerospace equipment revenue at 512 million yuan, accounting for 88.7% of total revenue.The proportion of compact general-purpose five-axis machine tools in total revenue increased to 6.8%, nearly sevenfold in three years. Although the current gross margin of compact general-purpose machine tool business is relatively low, mainly due to the impact of production capacity not yet being fully utilized, its strategic value lies in opening up broader general markets such as automotive, medical, and energy for the company.
This means that Topper CNC has not rigidly stuck to the aerospace track. Instead, it has honed its technology to the top level in this most challenging field and then brought this capability into larger markets such as automotive, medical, and shipbuilding.
This logic is similar to Huawei’s approach of rigorously developing technology using strict standards for communication equipment before expanding into enterprise and consumer businesses.
As the scale of operations in general-purpose fields gradually expands in the future, the company will form a dual-driven structure with 'aerospace equipment as the profit cornerstone and general-purpose machine tools as the growth engine,' further enhancing operational stability.
03
The 'hidden logic' of premium cornerstone investors: The investment focus is shifting from finished products to equipment.
The collective endorsement by cornerstone investors such as RBC, 3W, Boyu, Hillhouse, UBS, CDH, Cithara, Fidelity, China Asset Management, Shanghai Minhang, TT International, Mirae Asset, and Goldman Sachs sends a strong signal.
In the current Hong Kong IPO environment, institutions are generally cautious about manufacturing sector new listings. Attracting so many top-tier institutions simultaneously relies not on hype but on an accurate assessment of core industry chain issues.
Over the past three years, the primary market invested heavily in rocket, satellite, and engine companies, but the secondary market has consistently lacked a truly solid 'manufacturing-focused' pure-play. The emergence of Topper CNC fills this gap perfectly.It is neither a rocket manufacturer nor a satellite maker but rather the essential manufacturing equipment foundation that all rockets, satellites, and aircraft depend on.
This position as a 'pick-and-shovel provider' determines that its risk-return profile is completely different from that of finished product manufacturers. While finished product manufacturers might be swayed by the success or failure of a particular model, Topper CNC benefits from the certainty of demand driven by 'collective production expansion among downstream customers.'
Some may argue that when a gold rush fades, those selling shovels are often hit first. This analogy holds some truth but overlooks a key premise: if the gold in this land isn't just 'possibly present' but 'must be mined,' then the demand for shovel sellers will not wane.
Commercial aerospace precisely belongs to the latter category. It is not a short-term bubble created by capital but a strategic chip in the competition between major powers. In the 2026 government work report, aerospace was listed as an 'emerging pillar industry' for the first time, and the '15th Five-Year Plan' explicitly included it as a core direction for the cluster development of strategic emerging industries.
After all, frequency and orbital resources for low-orbit satellites are allocated on a 'first-come, first-served' basis; whoever moves slower will be at a disadvantage. This determines that regardless of whether a single satellite makes money or not, the quantity must increase, and production capacity must rise.
Under this logic,Top Ridge’s moat is not the technology itself but rather the 'time window' and 'switching costs.'
The certification cycle for aerospace-grade equipment typically lasts one to three years, or even longer. Customers’ process parameters, operating habits, and after-sales service systems become deeply tied to the equipment. Once put into use, replacing the supplier would be equivalent to reconstructing the production line, with extremely high costs.
This kind of first-mover advantage is almost irreversible in the industrial sector. It’s like once you get used to the iOS ecosystem, switching to Android involves costs beyond just changing your phone.
In addition, the prospectus shows thatthe market size for five-axis CNC machine tools is expected to grow from 12.9 billion yuan in 2025 to 35.2 billion yuan in 2030, with a CAGR exceeding 20%.Meanwhile, the aerospace sector's market reached 4.3 billion yuan in 2025. In such a track with strong certainty of prosperity, suppliers occupying the most central position naturally become targets regarded by institutions as 'long slopes and thick snow.'

Conclusion
Listening to too many stories about commercial space can easily create an illusion that the barrier lies in the moment of 'reaching space.' However, what truly determines who can continuously 'reach space' is ground-based manufacturing capability.
Only when the pricing of manufacturing equipment is fully understood by the market can the entire industry chain be said to have truly completed its commercial closed loop.
The IPO of Topper CNC, along with its impressive list of cornerstone investors, could very well mark the turning point in this narrative shift. As SpaceX ramps up production, the Chinese market has finally welcomed a highly recognizable 'high-end manufacturing infrastructure' stock, giving secondary market investors a chance to directly participate in this industrial transformation.
Ultimately, the first half of the commercial space race is about design capabilities and technological breakthroughs; but in the second half, the deciding factors will be the completeness of the manufacturing system, the consistency of equipment precision, and the maturity of mass production. In this grand transition from a 'launch narrative' to a 'manufacturing narrative,' whoever can turn manufacturing capability into an industry barrier will secure the most advantageous position in the next phase of competition.
