Business Details

Serving pharmaceutical companies, biotech ventures, universities and other customers, the business provides kinase protein sales (including mutant and biotinylated proteins), profiling services, NanoBRET™ Service and more. It specializes in the early stages of drug discovery research, supporting customers' drug discovery activities, and an important mission is to channel earned revenue to the Drug Discovery Business. The business operates globally across the US, Europe, China and other regions, capturing AI drug discovery companies and Chinese CROs as key customer segments.

Recent Overview

In Q1 FY2026 (ending March 2026), revenue was ¥183 million (up 28.1% year-on-year), and operating profit turned positive at ¥19 million

In Japan, protein sales to key customers performed well, and orders for profiling services and NanoBRET™ Service to pharmaceutical companies and biotech ventures expanded, resulting in a significant revenue increase of 104.3% year-on-year for the same quarter. In Europe, the company won a large profiling service order from a drug discovery biotech venture, driving growth of 167.7%. Protein sales to Chinese CROs were also strong, growing 54.4%. On the other hand, in the US, profiling orders from AI drug discovery companies temporarily declined, and large protein sales orders also decreased, resulting in a weak 37.1% decline. A new order from an AI drug discovery company won at the end of 2025 contributed to revenue in the current first quarter.

Key Products

product
Kinase Protein Sales

The core revenue driver. The company continues to strengthen its lineup of biotinylated and mutant proteins. Since last year, it began selling a new category, Pseudo Kinase (pseudokinase). It also sells related reagents such as assay buffer and substrate, comprehensively supporting customers in building their experimental systems.

service
Profiling Service

The company conducts contracted testing using the Mobility Shift Assay System, which only it can provide. Orders from AI drug discovery companies contributed to revenue. To expand its customer base, the company is also developing profiling services using new assay platforms that are in high demand among customers.

service
NanoBRET™ Service

Provided to pharmaceutical companies and biotech ventures. In Q1 FY2026 (ending March 2026), the service performed well in Japan and the US, contributing to revenue growth.

product
Assay Buffer/Substrate Reagent Sales

Sales began last year. In conjunction with the "Kinase Assay Support Portal" (available in Japanese, English and Chinese), the company provides an environment where customers can easily and efficiently build highly reliable experimental systems, promoting product usage.

service
Custom Protein & Custom Assay Services

The company provides an integrated service from custom protein development through to assay. It is also advancing R&D toward the commercialization of kinases and related proteins that are difficult to produce and not commercially available, despite existing market demand.

Growth Drivers

  • Expansion of orders for profiling services and NanoBRET™ Service to domestic pharmaceutical companies and biotech ventures
  • Acquisition of a large profiling project from a European drug discovery biotech venture
  • Continued strong kinase protein sales to Chinese CROs
  • Profiling service orders from AI drug discovery companies (new project won at the end of 2025, contributing to revenue in Q1 FY2026)
  • Meeting customer needs by strengthening the lineup of biotinylated proteins, mutant proteins, and Pseudo Kinase
  • Improved customer convenience and promotion of product usage through individual sales of assay buffer/substrate and the "Kinase Assay Support Portal" (available in Japanese, English and Chinese)
  • Differentiated competitive advantage as the only company able to provide the Mobility Shift Assay System

Risks

  • Risk that the temporary decline in profiling orders from AI drug discovery companies in the US market continues
  • Sharp decline in demand for protein sales and profiling due to major customers' shift in research phase (a decrease in large orders has become apparent in the US)
  • North America revenue declined significantly, down 37.1% year-on-year for the same quarter, and recovery in the US market remains uncertain
  • The profitability of the Drug Discovery Support Business is limited to Q1 alone, and stable profitability for the full fiscal year remains uncertain
  • Information security risk related to ensuring confidentiality of customer information (information barrier management with the Drug Discovery Business is required)
  • Foreign exchange risk (overseas revenue accounts for approximately 63% of consolidated revenue)
