Caster Co.Ltd. Q4 FY2025 earnings call

• Overall 2025 August Full Year Results: Revenue grew steadily year-over-year, reaching 99.3% of plan, and operating income came in 45 million yen above plan. The full year ended with an operating deficit due to unrecouped upfront investment from the first half, though Q4 operating profit improved significantly. Active client companies reached 1,316, up 10.4% year-over-year. ARPU declined temporarily due to rapid growth in low-value micro-lot contracts, and MRR also saw a temporary decline, while churn rate trended downward steadily. LTV/CAC exceeded appropriate levels significantly in Q4.
• New Service Launches & Operational Updates: 1. Launched ECHO BOARD, an AI agent service specialized for accounting and business management, currently in waiting list mode with early client deployments. The service automatically completes financial analysis from input financial data and fully discloses all analysis sources, reasoning steps, and evidence, a capability that generic AI tools like ChatGPT cannot provide, and has received strong demand from business owners. 2. Launched CASTER BIZ accounting for listed companies, a specialized plan for public enterprise accounting that can now be stably delivered after strengthening talent depth. 3. Launched NEO assistant, a service that designs, operates, and improves AI workflows for clients, with demand far exceeding current capacity. 4. Launched CASTER BIZ recruiting AI Talent Recruiting to meet market demand for AI-related hiring and process building. 5. Added self-serve sign-up functionality to My Assistant, the company's micro-lot service, with plans to add AI agent automation for client support. 6. Established CASTER TECH VIETNAM, a development subsidiary in Vietnam, to advance AI-powered VibeCoding development.
• Updated Corporate Strategy: Revised the corporate mission from "Make remote work the norm" to "Reinvent all of work" with an AI FIRST core strategy. The long-term vision is to dramatically improve Japanese labor productivity in the back-office space to address long-term population decline and the resulting demand for higher per-capita output. Growth priorities are: expanding in the small-lot and micro-lot markets, expanding into enterprise/niche segments, and optimizing the business portfolio. Micro-lot expansion is targeted through AI agent-powered sales to open up the underserved market of very small contracts that are uneconomical for traditional BPO providers, and micro-lot growth also naturally drives enterprise expansion by penetrating unaddressed niche department-level needs at large companies.

1. BPaaS Business: Overall segment revenue was flat year-over-year, with accounting, labor, and micro-lot segments driving growth while other segments remained flat. Segment profit decreased year-over-year due to heavy upfront investment in specialized accounting and labor talent in the first half of the period. The fourth quarter saw significant profit improvement following sales promotion strengthening and selling, general and administrative expense (SG&A) reduction initiatives. No revenue contribution percentages were provided in the transcript. 2. Other Business: The segment grew revenue year-over-year and improved profit, driven by full-year revenue recognition from new businesses and subsidiaries Grams and Caster Tech Japan (previously LUVO, renamed September 1, 2025). The segment is currently optimizing resource allocation to focus on AI-related areas. Starting from FY2026 August, the company will reorganize into three reportable segments: BPaaS, HR, and AI Tech, with profits from the two existing businesses to be invested into the AI Tech segment.

• The company expects continued revenue growth for FY2026 August, with a projected 27.8% CAGR for the medium term.
• Following the achievement of monthly profitability in late FY2025, the company targets full-year net profitability for FY2026 August through continued gross margin improvement and SG&A optimization.
• The medium-term plan expects the company to meet the Tokyo Stock Exchange's 10 billion yen (100 billion yen market capitalization requirement for Growth Market listings by 2030, with no plans to switch to the Standard Market at this time.
• Medium-term guidance does not yet include significant revenue contribution from AI Tech, with growth expected to come from incremental gains in existing businesses plus gradual new AI-related revenue build-up.

• High upfront investment in specialized accounting and labor talent led to full-year operating deficit in FY2025.
• Overly rapid expansion in micro-lot contracts could lead to sustained ARPU decline and unprofitable small-contract business if AI automation is not implemented successfully.
• AI hallucination and incorrect evidence generation is a key risk for financial AI services; the company has mitigated this by building mandatory source evidence disclosure into ECHO BOARD, and no hallucination events have been observed to date.
• The company operates in an immature AI agent market with no established best practices, requiring continuous trial and error for product development.
• Failure to achieve the TSE 100 billion yen market capitalization requirement by 2030 could result in delisting from the Growth Market.
• High transaction friction in small-lot BPO makes micro-lot expansion uneconomical without successful AI automation of sales and client support processes.

Q: What is Caster's top priority initiative for the coming period? / A: Management's top priority is the AI agent space, which is an immature market with no established dominant players, giving Caster a strong opportunity to capture a leading market position. Management is prioritizing capturing the first-mover advantage in this high-potential area.

Q: How can AI agents improve customer acquisition cost (CAC) for My Assistant's micro-lot business? / A: The company expects that fully AI agent-powered self-serve sales and client support, replacing human sales teams, can reduce CAC by up to 90% compared to current levels. This will make the currently uneconomical very small micro-lot contracts profitable, opening up a large new underserved market. No player has yet built this business model successfully, and Caster aims to be the first to bring it to market.

Q: How does Caster plan to balance revenue growth and margin improvement, and what is the long-term sustainable growth story? / A: Caster's cost structure has limited variable costs outside of talent hiring for service delivery, so revenue expansion naturally improves margin as fixed costs are spread over a larger revenue base. Growth from AI Tech and enterprise segment expansion will drive gradual margin improvement. Long-term growth relies on repeated cycles of developing high-productivity talent to serve clients, which is necessary to address structural labor scarcity from ongoing Japanese population decline.

Q: What are the most common churn reasons, and how does Caster mitigate churn risk? / A: The most critical churn driver is low first-contract renewal rates, most often caused by staff turnover at either the client or Caster side leading to unaddressed client needs, or misalignment between client expectations and delivered outcomes. Caster mitigates this through proactive early client communication to identify issues, and human-led relationship management to resolve problems before they lead to churn. Churn rate has declined steadily through these efforts.
