Key Products
Growth Drivers
- "Bill One" continued high growth, with the number of paid contracts up 31.9% year on year and MRR up 34.9% year on year, driven by a strengthened sales structure and new AI-powered feature development
- The number of "Sansan" contracts increased 14.0% year on year due to a strengthened sales structure, with steady progress in acquiring new small and medium-sized contracts
- The cloud invoice receipt service market continued its high growth in fiscal 2024, up 52.4% year on year; market expansion has continued even after the one-time surge in demand related to the Invoice System and Electronic Bookkeeping Act compliance subsided
- Amid the global expansion of AI-related investment, the company is strengthening its value proposition as data infrastructure in the AX (AI Transformation) domain, and promoting feature development premised on the use of generative AI
- Adjusted operating profit margin improved substantially from approximately 9.5% in the prior period to approximately 17.8%, driven by improved gross profit margin from revenue growth and lower personnel and advertising expense ratios
- New services such as "Contract One" and Nine Out, Inc.'s "Ask One" expanded rapidly, up 69.1% year on year, advancing revenue diversification within the segment
Risks
- "Sansan"'s trailing 12-month average monthly churn rate showed a gradual upward trend at 0.55% (up 0.06pt year on year), requiring continued efforts in customer retention
- While holding an 85.8% share of the corporate business card management service market, there is a risk of emerging competing services leveraging AI
- While "Bill One" has maintained growth even after the one-time demand related to Invoice System and Electronic Bookkeeping Act compliance subsided, there is a risk of growth slowdown as regulatory compliance-related demand fades
- Given the large volume of personal and corporate information handled, an information security incident would have a significant impact on the business and trust
- Goodwill amortization burden and integration risk associated with M&A investments such as the full acquisition of Nine Out, Inc. (acquisition cost of ¥1,412 million)
- Personnel expenses are expected to increase approximately 12% year on year and advertising expenses approximately 8% year on year in FY2027 (ending May 2027); cost control during this phase of expanded investment will affect profit margins
