NS : Notice of the 44th Annual General Meeting of Shareholders

To: Our Shareholders

I would like to express my sincere gratitude to you for your continued support.

While society undergoes various forms of change including the shrinking workforce and intensifying environmental issues, technological innovation is accelerating, as symbolized by the emergence of generative AI. There is growing potential for IT to solve problems that have been unsolved up to now.

NS Solutions Corporation will take these changes as opportunities and leverage digital technology, which is our strength, to actively initiate engagement with society and open up new possibilities.

With our PURPOSE, "Dream our future, unleash the possibilities of society, with technology and passion," we will promote sustainability management based on our value creation process, whereby contributing to the realization of a sustainable society as a member of the global community.

The NSSOL group has promoted business activities in accordance with the Medium-term Business Strategy 2021-2025. In the 44th fiscal year, we achieved record highs as well in both revenue and operating profit, exceeding our initial forecasts thanks to strong IT demand. Growth investments were also implemented smoothly as planned.

Given that the current Medium-term Business Strategy is outpacing the plan, and the external environment and IT megatrends are changing dramatically, we have positioned the fiscal year ending March 31, 2026, the 25th year of our establishment, as our second founding period and will launch new activities to prepare for the next stage. To lead the movement, we have formulated the "NSSOL 2030 Vision," which is what we aim for in 2030.

As the role of IT expands from solving the issues of individual companies and organizations to solving those of society as a whole and across industries, we aspire to grow out of our existing presence as a partner of individual companies and become a "producer" that envisions and realizes the future for society and businesses. We aim to achieve industry-leading business growth with the vision of becoming a "Social Value Producer with Digital" by 2030.

We ask for the continued understanding and support of our shareholders.

Yours truly,

Kazuhiko Tamaoki

Representative Director & President

NS Solutions Corporation
