Business
Rentracks Co., Ltd. is an internet advertising company founded in 2005 that operates four business segments centered on its core Performance-Based Advertising Service Business "Rentracks": the Programmatic Advertising Agency Business, the Used Construction Machinery Marketplace Business, and the Precious Metal Reuse, Processing and Refining Business. Built on a platform business model connecting advertisers, partner site operators, and buyers, the company forms a group consisting of 5 domestic subsidiaries and 13 overseas subsidiaries. In FY2026 (ending March 2026), consolidated net sales were ¥4,440 million, with performance-based advertising accounting for 50.7% and used construction machinery accounting for 38.8%. The company is listed on the Growth Market of the Tokyo Stock Exchange.
Business Model
In the Performance-Based Advertising Service Business, no initial or monthly fees are charged to advertisers; compensation is received only upon approval of results. Partner site operators ensure quality through closed-type screening, providing advertisers with high cost-effectiveness. The Used Construction Machinery Marketplace Business similarly operates on a fully performance-based trading intermediary model, setting low entry barriers for both sellers and buyers. The Programmatic Advertising Agency Business collects agency fees as an official agency for LINE Yahoo and Google.
Company Strengths
As of the end of March 2026, the number of partner site operators was 64,719 (up 3,974 year on year). Media quality is maintained through a closed-type screening system under which registration is only possible via referral from existing operators, and this provides a point of differentiation from competitors by enabling advertisers to reach an actively engaged consumer segment.
The used construction machinery platform operated by subsidiary GROWTH POWER supports Japanese, English, and Chinese, and revenue from Asia in FY2026 (ending March 2026) rose sharply to ¥1,353 million (from ¥899 million in the prior fiscal year). New sales channels have also been developed for Europe and other regions, and the fully performance-based fee model keeps entry barriers low for both sellers and buyers.
In the Programmatic Advertising Agency Business, the company holds official agency status with LINE Yahoo Corporation (contract signed in 2009) and Google Japan G.K. (terms agreed in 2011). It has built a system that comprehensively covers the major programmatic advertising platforms, and revenue from this business expanded rapidly to 316.0% year on year in FY2026 (ending March 2026).
ENVALITH's Perspective
Performance Trend
Revenue maintained an expanding trend for five consecutive fiscal periods, growing from ¥2,456 million in FY2022 (ended March 2022) to ¥4,440 million in FY2026 (ending March 2026). However, operating profit in FY2026 (ending March 2026) declined to ¥1,051 million (down 8.0% year on year), retreating from the previous period's record-high level, and the operating profit margin fell from 29.6% to 23.7%. M&A-related expenses and an increase in the provision for shareholder benefit programs, among other factors, weighed on profit. On the other hand, the recognition of a ¥2,079 million gain on negative goodwill arising from the consolidation of Ijima Kingin Kogyo as a subsidiary caused net income to surge to ¥2,570 million. Regarding the external environment, the internet advertising market maintained high growth in 2025, with media spending up 111.8% year on year, providing a tailwind for the core Performance-Based Advertising Service Business. For FY2027 (ending March 2027), the company projects revenue of ¥43,182 million reflecting the full-year consolidated contribution of Ijima Kingin Kogyo, but the profit margin is expected to decline significantly due to changes in the business portfolio and other factors.
Growth Strategy
Parallel advancement of deepening the core advertising business, overseas expansion of used construction machinery, and monetization of the precious metal reuse business
While continuing to focus on existing genres such as finance, automobiles, and beauty clinics, the company will strengthen sales efforts targeting advertisers in new fields such as retail products. Leveraging the expansion of the internet advertising market (media spending up 111.8% year-on-year in 2025) as a tailwind, the company aims to expand its industry share. Revenue from this business in FY2026 (ending March 2026) rose steadily to ¥2,253 million (up 2.6% year-on-year).
Revenue from Asia increased substantially in FY2026 (ending March 2026) to ¥1,353 million (from ¥899 million in the previous period), and new sales channels were also developed in Europe and other regions. Leveraging multilingual support and a fully performance-based fee model, the company will continue to expand transactions with overseas buyers. Continued growth of this business is expected in FY2027 (ending March 2027) as well.
Through Ijima Kingin Kogyo, which was made a consolidated subsidiary in February 2026, the company aims to cultivate the Precious Metal Reuse, Processing and Refining Business as a new pillar of earnings. In FY2026 (ending March 2026), the consolidation period was short and there was no impact on revenue or operating profit/loss, but in FY2027 (ending March 2027), revenue is expected to expand substantially due to the full-year consolidation contribution. In the first half, profit is expected to be squeezed by factors such as increased cost of sales associated with mark-to-market valuation of inventory, making early stabilization of earnings a key challenge.
The company will promote sales activities tailored to the market characteristics of each region at its domestic and overseas subsidiaries, aiming to improve overall group performance. It will maintain and strengthen the competitiveness of each business through the continuous acquisition of talented personnel. The Programmatic Advertising Agency Business expanded rapidly in FY2026 (ending March 2026), with revenue of ¥171 million (up 316.0% year-on-year).
