2. Revision of Full-Year Forecasts and Background
One of the most notable changes this quarter is the revision of the full-year earnings forecast for the fiscal year ending December 2026 . While the company initially provided guidance based on growth rates, the strong progress made in the first half prompted a shift to specific, bullish monetary ranges.
As shown in the slide above, the revised full-year revenue forecast is set at 10.768 billion to 10.958 billion yen (+13.0% to +15.0% YoY) . Profitability improvements are particularly striking, with EBITDA projected at 1.5 billion to 1.7 billion yen (+9.4% to +24.0% YoY) , operating profit at 620 million to 918 million yen (+28.0% to +89.3% YoY) , and net profit attributable to owners of the parent at 456 million to 753 million yen (+112.2% to +250.5% YoY) .
This revision is underpinned by revenue growth in the BPaaS domain exceeding expectations and improvements in the cost structure driven by company-wide productivity gains. As of the first half, the progress rate for EBITDA against the lower end of the full-year forecast has reached 62.5% , indicating that profit generation is accelerating faster than initially anticipated.
3. Major Milestone Achievement: 1 Million Corporate Clients and 10 Billion Yen ARR
A historic turning point in the kubell Group's growth story is the surpassing of major thresholds in both its customer base and recurring revenue scale.
As indicated in the slide above, 15 years after the launch of the business chat tool "Chatwork," the number of group service corporate clients has reached 1.004 million . Furthermore, the total company ARR (Annual Recurring Revenue) reached 10.23 billion yen (+17.3% YoY) , successfully achieving the target of 10 billion yen in ARR .
The strategic significance of this data goes beyond mere numbers. The customer base, consisting primarily of small and medium-sized enterprises (SMEs) across Japan, functions as a powerful "customer touchpoint (channel)" for the company. An ecosystem has been established to cross-sell BPaaS services , such as back-office support, to this massive customer base, enabling highly efficient expansion of ARPU (Average Revenue Per User) and LTV (Lifetime Value).
4. Q2 Financial Results and Profit Analysis
A detailed look at the financial figures for the second quarter (3 months) and the first half (6 months) of the fiscal year ending December 2026 reveals a significant jump in profitability alongside revenue growth.
H1 Performance (January–June 2026)
- Revenue : 5.276 billion yen (+16.4% YoY)
- Gross Profit : 3.8 billion yen (+25.6% YoY, Gross Margin: 72.0%)
- EBITDA : 938 million yen (+62.2% YoY, EBITDA Margin: 17.8%)
- Operating Profit : 556 million yen (+278.7% YoY)
- Net Profit : 490 million yen (Turned profitable from a 14 million yen loss in the same period last year)
In the second quarter alone (Q2 '26), revenue reached 2.689 billion yen (+17.1% YoY) , while EBITDA showed strong growth at 469 million yen (+60.6% YoY) .
The increase in gross margin from 66.8% in the same period last year to 72.0% (+5.2 points) is attributed to lower marginal infrastructure costs as revenue scales and a shift in the product mix toward higher-margin offerings. Additionally, the EBITDA margin of 17.8% is tracking ahead of the 2026 target range (10–15%) set in the mid-term management plan.
5. Domain Trends: Rapid BPaaS Expansion and Stable SaaS Foundation
kubell's business structure is broadly divided into the "SaaS domain" and the "BPaaS domain." By examining the ARR and revenue trends of both, the company's dual-engine growth structure becomes clear.
The "ARR Trends" slide above most directly illustrates the company's growth structure.
SaaS Domain (Chatwork, Storage, etc.)
- ARR : 7.92 billion yen (+6.4% YoY)
- Q2 Revenue : 2.044 billion yen (+5.0% YoY)
- Metrics : Registered IDs reached 8.231 million (+6.2%) , paid IDs reached 849,000 (+3.3%) , and ARPU was 734.5 yen (+1.8%) , indicating steady stock accumulation. Although the churn rate rose slightly to 1.17% due to the impact of phishing scams, it remains at a very healthy, low level within the industry.
BPaaS Domain (Taxita, Labor, Attendance, Invoice Receipt, etc.)
- ARR : 2.31 billion yen (+80.9% YoY)
- Q2 Revenue : 645 million yen (+84.0% YoY)
- Characteristics : The BPaaS domain, which provides back-office support for SMEs struggling with labor shortages by combining IT tools with human support (operators), is growing at an overwhelming speed of over 80% year-on-year. The lineup and expansion speed have been further bolstered by the addition of the mail-receiving business from "atena Inc.," which joined the group in April 2026.
6. AI Implementation and New Business (Labor and Social Security Attorney AI Agent)
In terms of product strategy, the active practical application of AI (Artificial Intelligence) technology is a major topic.
Within Chatwork, the company is sequentially implementing and providing AI features tailored to daily operations, such as "AI Summarization" for unread messages, "AI Draft Creation" to assist in writing, and automatic distribution of legal updates and labor news.
Furthermore, the launch of the "Chatwork Labor and Social Security Attorney AI Agent" business, which productizes the company's internal labor support expertise, is noteworthy. The AI agent automatically handles routine procedures, applications, and document creation previously performed by humans, allowing labor and social security attorneys to focus on higher-value consultation and dialogue. This is a concrete example of an "incubation model" that turns know-how gained from internal AI-driven efficiency into an external service, and it is expected to become a new pillar of revenue.
7. Cost Structure, Productivity, and Organizational Optimization
The dramatic improvement in profitability is supported by controlled SG&A ratios and increased productivity .
Looking at the expense structure, personnel costs for operators are on an upward trend due to the rapid expansion of the BPaaS business (headcount increased by 89 from the previous quarter to 824 , with 371 being BPaaS operators). However, the ratio of S&M (Sales & Marketing) and G&A (General & Administrative) expenses to revenue is declining , reflecting increased efficiency in advertising and outsourcing costs.
In July 2026, the company consolidated its headquarters into "WeWork KDX Toranomon 1-chome." By consolidating dispersed floors to improve work efficiency and utilizing flexible office space to achieve low-cost relocation, the company has successfully minimized the burden of fixed costs on its financial performance.
8. Conclusion and Future Outlook
kubell's earnings for the second quarter of the fiscal year ending December 2026 demonstrated that its business model—leveraging an overwhelming SME platform (SaaS) with over 1 million companies and combining it with a high-growth BPaaS domain —is functioning robustly.
Beyond revenue growth, the significant improvement in profitability, reaching a 72.0% gross margin and a 17.8% EBITDA margin , along with the upward revision of the full-year forecast, indicates that the company's earnings structure has moved to the next stage. Moving forward, attention will be focused on how the company progresses toward becoming the No. 1 BPaaS company for SMEs through the promotion of BPaaS cross-selling to existing customers, AI-driven productivity gains, and the deployment of new products.
