Report overview

Orders Grow in Space and Fusion, Profit Still Elusive

Vitzronextech is expanding revenue on the back of national space and fusion-energy projects such as the Nuri rocket, ITER, and KSTAR, but it posted an operating loss again in 2025 and remained in the red through the first half of 2026.

  1. 1

    2025 revenue rose 21.1% year over year to KRW 36.79 billion, but the company still posted an operating loss of KRW 7.36 billion and a net loss of KRW 6.60 billion.

  2. 2

    Both the operating and net losses narrowed to less than half of their 2024 levels, showing a clear improvement trend.

  3. 3

    Losses continued in both Q1 and Q2 2026, and the first-half operating margin was actually worse than the full-year 2025 figure.

  4. 4

    In August 2026 the company signed a KRW 53.5 billion contract with Hanwha Aerospace for Nuri rocket FM7-FM11 engine components, securing revenue visibility through 2029.

  5. 5

    Korea Investment & Securities, in a December 2025 report, pointed to 2027 as the turning point for profitability.

02

Business structure

Vitzronextech was established in 2016 through a spin-off of the special business division from Vitzro Tech and operates across four segments: aerospace, fusion energy, accelerators, and plasma applications.

The aerospace segment is the sole domestic designer and manufacturer of core liquid rocket engine components for the Korean-made Nuri rocket, with Hanwha Aerospace and the Korea Aerospace Research Institute as key customers.

In fusion energy, the company is one of the top four global specialists (and the only one domestically) in plasma-facing components, supplying internal protective devices to ITER and Korea's KSTAR fusion research reactor.

The accelerator segment has localized 80% of core parts such as klystrons and accelerating tubes, and has recently exported a total of 18 types of components to 33 countries for medical accelerators, container inspection systems, and non-destructive testing equipment.

The plasma segment is applied to radioactive waste volume-reduction equipment for KHNP and resource-recovery devices that carbonize and dry waste using high-temperature plasma pyrolysis technology.

As of 2024, revenue mix was 60.7% aerospace, 28.2% plasma, 4.6% fusion energy, and 5.7% accelerators, with aerospace accounting for more than half of sales. The company completed a new listing on KOSDAQ on November 21, 2025 under the technology growth (innovative technology) company requirements.

That said, some assessments note that the high-revenue aerospace and fusion businesses are largely publicly driven, carrying greater uncertainty and lower profitability than private-sector projects.

Earnings analysis

Consolidated revenue rose 21.1% from KRW 30.376 billion in 2024 to KRW 36.791 billion in 2025. Over the same period, the operating loss narrowed from KRW 14.065 billion to KRW 7.364 billion, and the net loss attributable to owners shrank by more than half, from KRW 15.441 billion to KRW 6.597 billion.

The operating margin improved sharply from -46.3% in 2024 to -20.0% in 2025, though the company has still not reached breakeven. In Q1 2026, revenue came in at KRW 7.121 billion with an operating loss of KRW 3.369 billion and a net loss of KRW 2.963 billion.

In Q2, revenue slipped slightly to KRW 6.670 billion, while the operating loss was KRW 3.120 billion and the net loss KRW 2.437 billion — an improvement in net loss versus the prior quarter.

However, the first-half 2026 operating margin of around -47% was actually worse than the full-year 2025 figure, illustrating how earnings can swing significantly by quarter depending on the timing of revenue recognition typical of government-led projects.

On the balance sheet, total equity grew substantially from KRW 35.834 billion in 2024 to KRW 58.953 billion in 2025, while the debt ratio fell from 163.7% to 93.0%, a shift attributable to the capital raised through the November 2025 KOSDAQ listing.

Operating cash flow, however, moved in the opposite direction — from an outflow of KRW 7.212 billion in 2024 to a larger outflow of KRW 8.780 billion in 2025 — suggesting that project-related working-capital assets that grew alongside revenue are weighing on cash generation.

05

Industry analysis

Korea's space industry is shifting toward a repeat-launch regime, as the government plans to launch at least one Nuri rocket every year through 2032 to raise the launch success rate above 90%, and the direction of next-generation launch vehicle development has also been reorganized at the government level.

In fusion energy, KSTAR and ITER continue to operate as long-term research infrastructure generating steady demand for related components, but schedule risk typical of large international projects persists, as the ITER project's completion timeline has stretched longer than expected, incurring additional costs.

The accelerator market is seeing diversifying demand from medical, industrial, and research applications, and the company has a track record of securing order references related to every accelerator currently operating in Korea, and has recently exported a total of 18 types of components to 33 countries to various private companies for medical accelerators, container inspection systems, and non-destructive testing equipment, suggesting room to expand through overseas private channels.

In terms of competitive positioning, both liquid rocket engine components and fusion-related plasma-facing components are areas with limited domestic alternative suppliers, giving the company high barriers to entry, though a structural limitation also exists in that security-related regulations make it difficult to secure new revenue sources through overseas expansion.

Additionally, the case in which a key customer, Hanwha Aerospace, delayed signing a supply contract amid a dispute with the Korea Aerospace Research Institute illustrates the vulnerability of a business structure dependent on a small number of customers and institutions.

Overall, while the industry itself benefits from policy tailwinds, earnings visibility remains limited given how heavily individual projects depend on order timing and budget allocation.

06

Outlook

The most concrete evidence is the contract disclosed on August 6, 2026 with Hanwha Aerospace, under which Vitzronextech secured a supply contract for core liquid rocket engine components for Nuri rocket units FM7 through FM11, worth about KRW 10.7 billion per vehicle for a total of KRW 53.5 billion covering five units.

The contract period runs from August 6, 2026 to November 30, 2029, giving the company revenue visibility extending more than three years forward.

This followed earlier contracts with the Korea Integrated Wind Tunnel Center and the Korea Institute of Fusion Energy, continuing a pattern of national-project orders across both the aerospace and fusion pillars.

Korea Investment & Securities stated in a December 2025 report that the company is expected to post operating losses through 2026, with a return to profitability possible in 2027 when significant top-line growth is expected, and in the same report forecast that mass production of final units is scheduled for an overseas research institution (government-backed) with which prototype contracts have already been signed in the fusion segment, while the timing for winning the main unit order in the heavy-ion accelerator construction project the company is participating in is expected around 2027.

The company has stated that it is supplying tungsten PFUs exclusively to KSTAR while pursuing expanded sales into private fusion projects, and plans to increase its product share within fusion reactor projects through new product development such as vacuum vessel ports and tungsten first-wall components.

That said, since these timelines are tied to multilateral international projects and government budgets, delays cannot be ruled out.

Because the company has remained in a net-loss position even after listing, a conventional price-to-earnings comparison is difficult to apply.

At the time of listing, the lead underwriter set the IPO price at the top of the indicative band (KRW 5,900-6,900) based on a high institutional demand ratio of 1,016 to 1, a price that was derived by applying the average P/E of 37.8x for comparable domestic and overseas companies (based on Q2 2025 LTM) to the company's projected 2027 earnings, then discounting the resulting per-share valuation by 22.0-33.3%.

In other words, the starting point of the market's valuation was explicitly premised not on current performance but on a return-to-profitability scenario several years out.

Relative to net assets, although shareholders' equity grew substantially through the capital raised in the 2025 KOSDAQ listing, the stock has continued to trade at multiples above that level in recent trading, which can be read as a premium to book value. The stock pays no dividend, making dividend-based metrics unhelpful for assessing its valuation.

Bull factors

Revenue Visibility Secured via Large National-Project Contracts

The KRW 53.5 billion Nuri rocket FM7-FM11 engine component contract signed with Hanwha Aerospace in August 2026 is significant because it locks in a long-term supply schedule through 2029.

Combined with earlier contracts with the Korea Integrated Wind Tunnel Center and the Korea Institute of Fusion Energy, orders continue across both the aerospace and fusion pillars simultaneously.

As long as the government maintains its plan for repeat launches and higher launch success rates, related component demand could continue over the medium to long term.

Entry Barriers from Rare Domestic Technology

Both core liquid rocket engine components and fusion-related plasma-facing components are areas with few alternative domestic suppliers, so the company's long-accumulated supply track record functions as a competitive advantage.

In the accelerator segment as well, it has localized a substantial share of core parts, giving it broad order references tied to accelerators operating domestically. These technology barriers make rapid catch-up by new entrants difficult.

Clear Narrowing of Loss Size

The operating loss narrowed from around KRW 14 billion in 2024 to about KRW 7.4 billion in 2025, and the net loss fell from roughly KRW 15.4 billion to about KRW 6.6 billion — both down by roughly half. Revenue also grew 21% over the same period, moving in tandem with improving profitability.

A securities firm has flagged 2027 as the turning point for earnings improvement, making it worth watching whether this trend continues in upcoming quarterly results.

09

Bear factors

Losses Persist, Profitability Delayed

The company posted operating and net losses in both Q1 and Q2 of 2026, and the first-half operating margin of around -47% was actually worse than the full-year 2025 level. A securities firm's projected turning point for profitability is 2027, meaning more than a year of continued losses likely lies ahead.

Given the nature of national projects, revenue recognition timing is dispersed, resulting in significant quarter-to-quarter earnings volatility.

Constraints on Profitability and Overseas Expansion from a Public-Sector-Driven Revenue Structure

The aerospace and fusion businesses, which account for the bulk of revenue, are largely driven by public-sector orders and are assessed as less profitable than private-sector projects. Security-related regulations also make it difficult to secure new revenue sources through overseas market expansion.

There has indeed been a case where a supply contract was delayed due to a dispute between a key customer and an ordering institution.

Pressure on Cash Generation

Even in 2025, when revenue grew, operating cash flow recorded a larger outflow than the prior year. Given the project-based revenue structure, growth in work-related assets such as inventory and unbilled construction appears to be causing cash collection to lag the pace of earnings improvement. The possibility of continued need for additional external funding cannot be ruled out.

10

Risk factors

Business Execution/Schedule Risk

As seen with large international fusion projects like ITER whose completion timelines have stretched, national and multilateral projects can see revenue recognition delayed due to design changes or budget adjustments.

Subsequent Nuri rocket launches and next-generation launch vehicle development could also see their schedules adjusted depending on government policy direction. In such cases, the actual pace at which the company's contract backlog converts to revenue could differ from expectations.

Customer and Geopolitical Risk

A significant portion of revenue is concentrated among a small number of large customers and institutions, including Hanwha Aerospace, the Korea Aerospace Research Institute, and the Korea Institute of Fusion Energy.

Defense- and space-related technologies are subject to security regulations that limit overseas market expansion, and there is precedent for disputes between ordering institutions leading to delayed supply contracts.

Without further customer diversification, the delay of any single contract could have an outsized impact on overall results.

Financial/Capital Risk

While the debt ratio fell thanks to capital raised in the 2025 KOSDAQ listing, the company remains in a phase of continued net losses and negative operating cash flow.

If the turn to profitability is delayed, additional funding such as a rights offering or convertible bonds may become necessary, which could dilute shareholder value. The pace at which project-related inventory and unbilled construction assets are collected is also a variable affecting financial soundness.

11

What to watch next

  1. Around November 2026 (expected Q3 report filing)

    This is a point to check whether Q3 2026 revenue and operating results break out of the first-half loss pattern, and whether initial revenue recognition from the August Nuri FM7-FM11 contract begins.

  2. Q4 2026

    More concrete details on the government's next-generation launch vehicle timeline and subsequent Nuri launch plans may be disclosed, warranting attention to whether related component orders expand.

  3. During 2027

    Whether the main-unit order for the heavy-ion accelerator construction project and the start of final-unit production for an overseas fusion research institution, both cited by Korea Investment & Securities, actually materialize is a key variable for the profitability outlook.

  4. At the time of full-year 2027 results release

    Since this is the year flagged by a securities firm as the profitability target, full-year results should be checked for whether operating profit is achieved and for the pace of revenue growth.

12

Overall view

Vitzronextech is a national-project-centered company holding technology areas with few domestic substitutes, including liquid rocket engine components for the Nuri rocket, fusion parts for KSTAR and ITER, and accelerator and plasma application equipment. 2025 revenue rose 21.1% year over year to roughly KRW 36.8 billion, with both the operating and net losses shrinking to less than half their prior levels — but the quarterly operating margin remained around -47% through the first half of 2026, indicating that breakeven still requires more time.

The KRW 53.5 billion Nuri FM7-FM11 contract signed with Hanwha Aerospace in August 2026 is positive in that it secures revenue visibility through 2029, but the structural characteristic of results being driven by public-institution order timing and budgets remains unchanged.

A securities firm has flagged 2027 as the turning point for profitability, and quarterly results and additional order disclosures in the interim will provide the basis for judging whether this outlook materializes.

Investors should weigh the schedule risk inherent to national projects, dependence on a small number of customers, and the ongoing net-loss and negative-cash-flow phase together.
