Haseko Livenet's June 2026 survey on real estate investment found that appetite for residential property remained firm despite rising interest rates and the impact of conditions in the Middle East. Investors weighed high liquidity against concerns about rising prices. Increased rental income and strong property sales are supporting investment activity.
Haseko Corporation has published the "Haseko Group Integrated Report 2026" on its website. The report introduces the initiatives and progress of the first year of the new medium-term management plan "HASEKO Evolution Plan," which started in fiscal year 2025.
Haseko Corporation stated that it aims for a 15% profitability at the time of order and seeks to recover profits during the construction phase, and that the profit margin has improved better than expected. It will continue to strive to improve construction profit margins, but will respond cautiously, taking into account market conditions and the balance with business profitability. It indicated that profit recovery can be maintained steadily due to rising material costs and site improvements.
Haseko Corporation's revenue and net profit increased compared to the first quarter of FY2026. Operating profit and ordinary profit also exceeded the same period last year, and the net profit attributable to shareholders increased by approximately 68.5%. Total assets and net assets also increased, and the equity ratio is 42.1%.
Haseko Corporation announced its consolidated financial results for the first quarter of the fiscal year ending March 2027. It reports detailed figures for sales and profits, as well as the status of overseas operations and real‑estate related businesses. It also touches on future business outlook and investment status.
Haseko Corporation plans to dispose of 4,151,500 common shares at ¥2,659.5 per share on August 21, 2026. This disposal is related to additional contributions to the Stock Benefit Trust (BBT) and the stock-based ESOP, with the trust beneficiary being Japan Custody Bank. A special report regarding the disposal will be filed in accordance with the Financial Instruments and Exchange Act.

Employees have engaged in environmental conservation activities a total of 22 times, involving 892 people. The company plans to continue actively engaging in biodiversity conservation activities, aiming to enhance environmental awareness and preserve the natural environment.
