Growth Drivers

  • User expansion through Chatwork's PLG strategy: the number of paid IDs expanded to 845 thousand (up 38 thousand year on year), while ARR maintained and grew to ¥7,322 million
  • Expansion of cross-selling in the BPaaS domain: cross-selling initiatives into BPaaS leveraging Chatwork's broad customer base have been successful, contributing to cost of sales efficiency (decreasing from ¥744 million to ¥705 million year on year) and improved gross margin
  • M&A roll-up strategy: expanded BPaaS value proposition through the acquisition of the Paytner Invoice business (Fintech entry) and the resolution to make atena Inc. a wholly owned subsidiary (cloud mail)
  • Stability of the recurring revenue model: the majority of revenue is subscription-based revenue (contract liability balance of ¥2,290 million), providing a stable, ARR-based earnings foundation
  • Continued expansion of DX demand among small and medium-sized enterprises: maintaining Japan's No.1 position in the business chat market amid ongoing needs for labor productivity improvement and digitalization in the domestic SME market

Risks

  • Risk of deviation from mid-term management plan targets: against the FY2026 (ending December 2026) revenue target of ¥15.0 billion, the full-year forecast remains at ¥10,768 million or more (+13% or more), requiring substantial upside to achieve the target
  • Labor-intensive nature of the BPaaS business: labor and personnel costs are increasing as the business expands, making productivity improvement through AI and technology utilization key to maintaining profitability
  • M&A and PMI risk: with an aggressive M&A strategy including the Paytner Invoice business acquisition and the full subsidiary conversion of atena, there is a risk of delays in post-acquisition organizational integration (PMI) or failure to achieve expected synergies
  • Risk of intensifying competition: intensifying competition in the business chat market with major domestic and international players such as Microsoft Teams, Slack, and LINE WORKS
  • Security risk: given its nature as infrastructure handling confidential information and personal data of numerous companies, cyberattack and information leakage risks are directly linked to business continuity
