ESTsoftCorp

ESTsoft started with the national utility ALTools and Korea's leading antivirus ALYac, and has since grown into a diversified group spanning AI/SW, games, portal, commerce, and asset management.

The core pillar is the AI/SW business, which delivers AX (AI transformation) solutions and AI education services through the real-time AI avatar service Perso Interactive, the generative service Perso AI, and the agentic AI Alan.

The gaming business, run through subsidiary ESTGames, generates revenue led by the new title Cabal RED, while the security business, ALYac from subsidiary ESTsecurity, has long held share in the domestic antivirus market.

The portal business operates the Zum search-news-content service through subsidiary ESTAID, which is now attempting a shift toward an AI search agent. Commerce and asset management exist as separate business lines, with first-half 2026 asset management revenue of KRW 9 billion, up 7% year over year.

The customer base splits between B2C (utility, antivirus, and portal users) and B2B (companies adopting AX solutions and AI avatars), with recent expansion into retail touchpoints such as an AI shopping assistant developed with CJ Olive Young.

Competitively, ESTsoft faces large telecom and platform players such as SK Telecom, Kakao, and KT in the AI agent market, and established antivirus vendors such as AhnLab in security.

Overall, the group's revenue structure combines multiple small business units, causing each segment's profit contribution to swing significantly from quarter to quarter.

Annual revenue rose for four consecutive years, from KRW 88.77 billion in 2022 to KRW 92.48 billion in 2023, KRW 102.46 billion in 2024, and KRW 106.79 billion in 2025, yet the operating loss widened over the same period from KRW 5.67 billion to KRW 8.91 billion, KRW 13.46 billion, and KRW 18.95 billion, showing a disconnect between top-line growth and profitability.

The net loss attributable to owners also grew, from KRW 6.10 billion in 2022 and KRW 6.17 billion in 2023 to KRW 11.65 billion in 2024 and KRW 17.73 billion in 2025, while operating cash flow swung from a positive KRW 199 million in 2022 to outflows of KRW 4.64 billion in 2023, KRW 2.99 billion in 2024, and KRW 17.68 billion in 2025.

On a quarterly basis, 2Q25 came close to breakeven with an operating profit of KRW 81 million, but losses widened sharply in the second half to KRW 4.48 billion in 3Q25 and KRW 10.19 billion in 4Q25.

In 1Q26, revenue reached KRW 30.98 billion with an operating loss of KRW 1.67 billion, a large improvement year over year, and net income attributable to owners turned positive at KRW 175 million.

However, 2Q26 revenue fell 4.7% year over year to KRW 29.74 billion (versus KRW 31.21 billion) and the operating result flipped back to a loss of KRW 332 million, underscoring significant quarter-to-quarter volatility.

Still, cumulative first-half 2026 revenue reached a record KRW 60.7 billion, and the cumulative operating loss of KRW 2.0 billion was 53.3% smaller than the KRW 4.29 billion loss a year earlier, indicating a profitability improvement trend on a half-year basis.

By segment, AI/SW revenue drove growth in the first half of 2026 at KRW 30.3 billion (up 18.3% year over year), while gaming reached KRW 16.4 billion (up 2.9%) and asset management reached KRW 9.0 billion (up 7%).

The sharp loss expansion in 4Q25 appears to have carried a strong one-off cost element, and with losses narrowing over the following two quarters, the repeatability of that improvement is a key point to watch going forward.

Korea's AI software industry is in a phase where government-led promotion of a domestic AI ecosystem and large-scale investment by major telecom and platform operators are advancing simultaneously.

The Ministry of Science and ICT's 'AI for All' project, aimed at universal access to domestic AI services, ultimately selected the SK Telecom, Kakao, and KT consortia as operators, who will receive large-scale infrastructure support including 512 Nvidia B200 GPUs.

ESTsoft participated at the group level, combining ALYac, ALTools, and Zum services, but was excluded from the final list.

As a result, ESTsoft must now operate its personal AI agent Albiseo with its own resources rather than government support, making small language model (SLM) adoption and model optimization to cut inference costs a key factor for expansion.

In the security market, amid rising AI-driven threats, ESTsecurity launched ALYac Agentic EDR to address AI security demand, with ALYac's existing user base—detecting and blocking roughly 200 million malware incidents annually—cited as a competitive asset.

In the portal market, dominant players such as Naver and Daum retain overwhelming positions, while Zum is in an early stage of attempting differentiation through a shift toward an AI search agent.

In K-content AI dubbing, ESTsoft has been selected for the K-FAST program for two consecutive years, maintaining its position as a supporter of overseas content distribution.

Overall, the AI services market remains in an early expansion phase, but as a small-to-mid-sized software company with relatively limited capital compared to large platform operators, selection outcomes in government policy projects and the burden of GPU and infrastructure costs are important variables in its growth path.

Although ESTsoft was not selected as an operator for the government's 'AI for All' project, the company plans to launch its personal AI agent Albiseo, which it had already been developing, in the second half of 2026 as scheduled, and intends to expand its features to deep research, public services, and an AI human mode, targeting 10 million monthly active users by 2030.

Albiseo will start this year centered on chatbot functions, with a sequential rollout of an evidence-based 'deep research' feature, a 'skill wish store' for linking external apps, and an 'AI human mode' aimed at elderly users.

In the AI/SW business, expansion of the real-time AI avatar Perso Interactive into retail and mobility applications at home and abroad is underway, including an AI shopping assistant using a real-time conversational AI avatar launched with CJ Olive Young for K-beauty retail settings.

In security, the company plans to grow ALYac Agentic EDR as a new revenue source, and has been selected for the K-FAST program supporting overseas distribution of Korean content for two consecutive years, continuing to send AI-dubbed content to North America and Australia.

Management has stated its intent to pursue both revenue growth and profitability improvement in the second half through synergies with AI national projects such as AX and talent development, sustained popularity of the new game Cabal RED, and continued intensive cost efficiency measures.

However, since ESTsoft's own AI agent business, including Albiseo, must bear inference costs without government support, the actual pace of user growth and the company's cost-management ability are likely to be key points to watch in future results.
