Suresofttech

Founded in 2002, SureSoftTech specializes in verifying mission-critical software, focusing on developing and supplying automated verification tools along with verification services.

Based on the H1 2023 business report, revenue was split among code verification solutions (46.4%), system verification solutions (25.8%), future-technology verification solutions (18.8%), and model verification solutions (9.0%), with automotive accounting for an overwhelming 75.6% of industry mix at the time, followed by defense/aerospace at 12.2% and nuclear/energy at 5.0%.

Analysts have since noted the automotive share fell to around 44% in 2024 before climbing back above half to 56% in H1 2025.

The company has partnered with the Hyundai Motor Group on vehicle software safety verification since around 2010, with key customers including Hyundai Motor, Hyundai Mobis, and Hyundai Kefico in automotive; Hanwha Group companies, Korea Aerospace Industries, and LIG Nex1 in defense; and Doosan Enerbility in nuclear.

In 2022 it also secured an overseas software contract related to NuScale Power's small modular reactor business in the United States.

Subsidiaries include the wholly owned U.S. entity V-cubed Solutions Inc, and in August 2023 the company acquired a 43.7% stake in big data and AI Ops specialist Mobigen for KRW 22.9 billion, consolidating it from the fourth quarter of that year.

Mobigen supplies big data analytics and AI Ops solutions to telecom operators, large system integrators, and public institutions, and carries seasonality with revenue concentrated in the fourth quarter given its heavy public/financial sector weighting.

The company listed on KOSDAQ in April 2023 via a merger with NH Special Purpose Acquisition Company 22, and is understood to face no clear direct domestic competitor in mission-critical software verification.

2025 consolidated revenue rose to KRW 93.94 billion from KRW 88.80 billion in 2024, while operating profit jumped to KRW 12.60 billion from KRW 7.89 billion, lifting the operating margin from 8.9% to 13.4%.

Net income attributable to owners, however, actually declined to KRW 8.58 billion in 2025 from KRW 10.81 billion in 2024, a gap that stems from the difference between total consolidated net income (KRW 10.08 billion in 2024, KRW 9.63 billion in 2025) and the owners' share.

In 2024, owners' net income exceeded total consolidated net income, while the opposite held in 2025 — a pattern that can be linked to year-to-year swings in the profit contribution of non-controlling shareholders in Mobigen, in which the company held a 50.5% stake as of Q3 2024.

On a quarterly basis, revenue bottomed at KRW 21.50 billion with operating profit of just KRW 0.19 billion in Q2 2025, before rising to KRW 23.57 billion / KRW 3.60 billion in Q3 and KRW 31.95 billion / KRW 10.90 billion in Q4, a clear back-loaded pattern that also reflects Mobigen's fourth-quarter revenue concentration.

That momentum reversed in Q1 2026, when revenue fell to KRW 20.22 billion and the company posted an operating loss of KRW 0.42 billion, before recovering in Q2 2026 with revenue of KRW 26.45 billion, operating profit of KRW 2.76 billion, and owners' net income of KRW 2.78 billion.

Summed over the most recent four quarters (Q3 2025 through Q2 2026), owners' net income totaled roughly KRW 11.40 billion, indicating a profit base that has persisted on an annualized basis as well.

On the balance sheet side, the debt ratio has steadily declined from 74.6% in 2022 to 46.8% in 2025, while operating cash flow grew from KRW 9.34 billion in 2022 to KRW 17.90 billion in 2025, pointing to improving cash conversion of earnings.

In the automotive end-market, the shift toward Software Defined Vehicles (SDV) is the central theme, and SureSoftTech has expanded from automotive controller testing and verification into developing verification solutions specialized for automotive software.

As controller software complexity rises, the importance of verification grows correspondingly, and because verification work handles sensitive information, automakers face difficulty easily diversifying verification partners — a factor cited as a competitive advantage.

In defense, the company has a track record of supplying Hardware-In-the-Loop Simulation (HILS) system verification services to Hanwha Aerospace, with defense-related revenue understood to correlate more closely with individual defense companies' R&D spending capacity than with their export performance.

In nuclear energy, the company has a track record of verifying instrumentation and control systems (MMIS) based on international standards for clients including Doosan Enerbility, and has also won a software contract related to NuScale Power's small modular reactor (SMR) business in the United States, drawing attention amid the expanding global SMR market.

Through the Mobigen acquisition, the company has broadened into AI and big data verification (future-technology verification solutions), positioning itself to address growing software testing demand as AI and machine learning applications expand in areas such as autonomous driving.

With no clear direct domestic competitor identified in mission-critical software verification, some assessments view the company as positioned to capture a substantial share of demand growth as the underlying industries expand.

Q1 2026 results reportedly showed revenue up 19.5% year on year, the operating loss narrowing 80.1%, and net income turning positive, with the company identifying automotive software as the core growth area and emphasizing the close relationship between the global SDV transition and its software testing and verification business.

The company is pursuing expansion into the Trustworthy AI domain through its Safe Intelligence business, positioning related solutions and certification programs to support customers' adoption of AI safety measures.

In the automotive segment, the company has moved beyond pure verification to directly developing certain controller software for next-generation vehicles, expanding into a comprehensive automotive software engineering partner role — a development worth monitoring for future revenue mix shifts.

Given Mobigen's pronounced fourth-quarter revenue concentration, second-half performance is likely to continue driving the full-year outcome. In nuclear energy, further progress on projects tied to NuScale Power and the broader U.S. SMR market expansion is cited as a potential source of additional order momentum.

That said, these directions reflect expectations expressed by the company and the market, and uncertainty remains until specific order sizes and timing are confirmed through disclosures.
