Notice Regarding the Formulation of the Medium-Term Management Plan

Mitsui Matsushima Holdings Co., Ltd. (the "Company") has formulated a medium-term management plan with the fiscal year ending March 2030 as its final year and hereby announces an outline of the plan as set forth below. For further details, please refer to the attached material.

  1. Background and Vision of the Medium-Term Management Plan

    For more than a decade, the Mitsui Matsushima Group has promoted M&A activities focused on market-leading niche companies primarily in the manufacturing sector and has successfully established a stable business portfolio to replace its founding coal business.

    Building on this, in May 2024, the Company announced its three-year "Management Strategy 2024," covering up to the fiscal year ending March 2027, which set forth aggressive M&A investments and shareholder returns. As these initiatives were steadily executed, the Group achieved, one year ahead of schedule, the establishment of an earnings base targeted at net profit of 5 billion yen or more.

    Following this, starting in the current fiscal year, the Company formulated a new "Medium-Term Management Plan 2030" and established the following numerical target and shareholder return policy.

  2. Numerical Target

    Net profit of 10 billion yen or more (fiscal year ending March 2030)

  3. Shareholder Return Policy

The Company adopts progressive dividends as its basic policy and aims to achieve a sustainable increase in annual dividends per share through profit growth.

In addition, the Company targets a dividend payout ratio of approximately 40% (assuming an annual dividend per share of 100 yen or more) for the fiscal year ending March 2030.

While placing emphasis on investment discipline and capital efficiency, the Group will continue to pursue M&A of market-leading niche companies with reliable technological capabilities and aims to become a corporate group that protects and nurtures Japanese manufacturing for the next 100 years.
