Business Model
Revenue is broadly composed of three layers. Products & Services (net sales of ¥5,751 million) consists of LifeKeeper license and support revenue as well as SaaS/subscription-type ARR revenue from the Gluegent series. Consulting & Integration (¥3,459 million) consists of project-based revenue such as system development for financial institutions and educational institutions and Generative AI Implementation Support. Software Sales & Solutions (¥9,860 million) consists of sales agency and technical support for OSS-related products such as Red Hat, Inc. and Elastic N.V. Otsuka Corporation (28.5% of net sales) and Networld Corporation (12.0%) are the main sales channels.
Company Strengths
1997年創業以来OSSを事業の軸に据え、HA製品「LifeKeeper」(米国子会社SIOS Technology Corp.を通じグローバル展開)、クラウドSaaS「Gluegentシリーズ」等の自社製品を保有。Red Hatとは2003年のパートナー契約・2008年のDistribution契約を締結し、OSS商流における確固たる地位を確立している。
-> Since its founding in 1997, the company has positioned OSS (open source software) as the core of its business, holding proprietary products such as the HA (high availability) product LifeKeeper (deployed globally through its U.S. subsidiary SIOS Technology Corp.) and the cloud SaaS Gluegent series. It signed a partner agreement with Red Hat in 2003 and a Distribution agreement in 2008, establishing a solid position in the OSS distribution channel.
GluegentシリーズへのAI機能搭載(AIワークフロー・パスワードレス認証等)によりARRが伸長し、プロダクト&サービスセグメントの利益は726百万円(前年同期比48.0%増)、利益率12.6%を達成。外部環境変動に左右されにくいストック型収益基盤の構築が進んでいる。
-> The addition of AI functionality to the Gluegent series (AI workflow, passwordless authentication, etc.) has driven ARR growth, with the Products & Services segment achieving profit of ¥726 million (up 48.0% year on year) and a profit margin of 12.6%. Progress is being made in building a recurring revenue base that is less susceptible to changes in the external environment.
2025年12月期において、EBITDA目標122百万円に対し実績460百万円、ROIC目標2.8%に対し実績14.2%と、いずれも計画を大幅に上回った。販売費及び一般管理費の前年同期比404百万円削減が主因であり、コスト構造改革の実効性が数値で確認された。
-> In FY2025 (ending December 2025), EBITDA reached ¥460 million against a target of ¥122 million, and ROIC reached 14.2% against a target of 2.8%, both substantially exceeding plan. The main driver was a ¥404 million year-on-year reduction in selling, general and administrative expenses, confirming the effectiveness of the cost structure reforms in numerical terms.
ENVALITH's Perspective
Performance Trend
In 1Q FY2026 (ending December 2026), revenue reached ¥5,895 million (up 18.1% year on year), operating profit reached ¥177 million (up 159.4% year on year), and quarterly net income attributable to owners of the parent reached ¥133 million (up 242.2% year on year), marking substantial improvement across all metrics. Looking at the trend over the past five fiscal years, revenue peaked in FY2024 (¥20,562 million) before adjusting down to ¥19,060 million in FY2025, but FY2026 (ending December 2026) full-year guidance calls for revenue of ¥20,000 million (up 4.9% year on year), pointing to a return to a growth trajectory. As an external factor, the rapid expansion in demand for generative AI and AI agents is directly driving increased orders for Elastic N.V. Related Products and AI Implementation Support, and steady IT investment demand is supporting the business recovery. Full-year guidance remains unchanged, and 1Q progress rates were solid at 29.5% for revenue and 39.4% for operating profit.
Growth Strategy
Pursuing sustainable growth through three pillars: expansion of the stock-type business model, leveraging generative AI, and developing API Solutions
The company positions the expansion of stock-type revenue centered on SaaS, subscriptions, and maintenance contracts as its most important strategy. Period-recognized revenue in the first quarter of FY2026 (ending December 2026) expanded to ¥2,069 million from ¥1,991 million in the same period of the previous year, driven by the migration to new pricing plans for the Gluegent series and growth in the number of users.
The company is promoting the standard installation of generative AI functions in the Gluegent series, the deployment of the Elastic N.V. Related Products (RAG Implementation Consulting Service), and the expansion of orders for the Generative AI Implementation Support business. In the first quarter of FY2026 (ending December 2026), Elastic N.V. Related Products significantly increased sales (up 28.6% year on year), and the capture of AI-related demand has materialized as a concrete contribution to results.
The company is promoting continued license sales and expansion of service order intake in the API Solutions domain, as well as strengthening the acquisition of projects for System Development & Implementation Support for Financial Institutions. In the first quarter of FY2026 (ending December 2026), the Consulting & Integration segment profit margin improved significantly to 18.0% (from 11.4% in the same period of the previous year), reflecting the effects of measures to strengthen profitability.
