    Forecast for FY 2026

    ©Tsukishima Holdings Co., Ltd. All Rights Reserved. 10



    Forecast for FY2026

    Orders received, net sales, and operating profit are expected to hit record highs

    • Orders received are expected to increase, supported by large-scale projects in the Water Environmental Business and continued strong performance in the Industrial Business.

    • Net sales are expected to increase as projects in the order backlog progress in both businesses.

    • Operating profit is expected to increase, mainly due to higher profit in the Water Environmental Business.

    • Profit attributable to owners of parent is expected to decrease due to the absence of gains from the sale of logistics facilities in the previous fiscal year.

Impact of military conflict in the Middle East

Although we do not expect a significant impact on overall business performance, we are closely monitoring the situation, as the potential impacts listed below are anticipated.

[ Orders received ]

  • Potential impact on customers' capital investment decisions in the Industrial Business. [ Net sales, Operating profit ]

  • Increased costs due to rising prices and delivery delays due to procurement difficulties of petroleum-derived products

  • Challenges in securing utilities (chemicals, etc.) for operation and maintenance business in the Water Environmental Business, as well as rising costs.

⇒Although we plan to recover costs through negotiations with customers,

the magnitude and outlook of the impact remain difficult to estimate at this point.

Forecast for FY2026 : Order trend and order backlog for Water Environmental Business Order Trends
  • Orders received decreased in FY2025 due to a transitional period between large-scale projects.

  • In FY2026, a significant increase is expected, including multiple large-scale projects.

  • Order backlog remains at a high level, ensuring that sufficient resources for sales have been secured.

    Breakdown of Order backlog
  • Order backlog at beginning of fiscal year remains at a high level of 271.5 billion yen

  • The ratio of water infrastructure (EPC) to life cycle business (O&M) is approx. 30:70

  • In Water infrastructure, construction periods tend to become longer due to delays in separately contracted civil engineering works, growing scale of projects and restrictions on overtime work.

  • In Life cycle business, the proportion of long-term projects is on the rise as orders for PPP projects such as PFI and DBO remain strong, with the increasing volume of these projects.

Features of our financial results
  • Sales recognition is concentrated in the 4th quarter

  • Project lead time from order receipt to delivery depends on the order amount, project size, and level of difficulty.

    Example) For equipment, small to medium scale projects : approx. 1 to 2 years For large-scale projects (several billion yen level): approx. 3 to 5 years

  • In recent years, the lead time for large-scale projects in the water environmental business has tended to increase to a multi-year basis due to the following factors.

EPC : Larger-scale projects, along with extended construction periods due to overtime regulations, as well as delays in separately contracted civil engineering work, have contributed to longer project schedules.

O&M: An increase in long-term operations and maintenance contracts, such as PFI and DBO projects, with contract periods of up to 20 years.

⇒ ⇒ ⇒

  • In recent years, the demand for finer particles and higher sphericity has been increasing to enhance battery performance. As particle sizes become smaller, the requirements for post-crystallization processes such as Filtration, Drying, and Crushing, also become more stringent. In response, new technologies have been added to the product lineup. (We are advancing the application of this technology beyond the battery sector)

  • We are enhancing market development and sample-based contract.

  • Requests for testing as well as inquiries regarding next-generation all-solid-state batteries are increasing.
