the Daigas Group

Co-creation of Value

We would like to extend our warmest greetings to all stakeholders as we issue this Integrated

Report.

The COVID-19 pandemic has been significantly impacting daily life and economic activity since the previous year. At the Daigas Group, we have been working hard to provide the stable supply of energy and maintain safety, as a corporate group responsible for social infrastructure. And we are rediscovering the weight of this responsibility on a daily basis.

Over the past 115 years since beginning to provide gas for lighting gas lamps in 1905, our gas business has expanded its application to heat source for residential, commercial, and industrial purposes to electric power generation, in response to social and environmental changes. The Daigas Group has worked to evolve as a corporate group that can meet the needs of customers and society through providing gas and electricity, as well as various related products, services, and solutions to support lifestyles and businesses.

The Daigas Group's principles and spirit are reflected in Our Corporate Motto "Service First" and in What We Aim to Be, "a corporate group that powers continuous advancement in customers' lives and businesses," which each employee takes to heart. We believe that it is the management's mission to apply these unwavering corporate principles and values to the greatest extent possible to the Daigas Group's corporate activities, regardless of changes in the times or the environment.

In the age of COVID-19 and even afterward, there will never be a change in the Daigas Group's original intention to genuinely engage with and serve customers and society. We are committed to maximizing value for all stakeholders, including customers and shareholders, and working toward realizing sustainable growth. As we work to meet the commitment, we aim to evolve into "an innovative energy and services company that continues to be the first choice of customers," which is our goal set in the Long-Term Management Vision 2030.

In March 2021, we announced the Daigas Group Medium-Term Management Plan 2023: Creating Value for a Sustainable Future, following the Daigas Group Carbon Neutral Vision released in January. Under the Plan, we will strive to create value for a sustainable future, which consists of achieving a low carbon / carbon neutral society, establishing lifestyles and businesses adjusted to the new normal, and enhancing resilience of customers and society. Creating this value will fulfill our corporate purpose of contributing to society by solving social issues.

As we pursue the goals set in the current Medium-Term Management Plan, we deeply appreciate the continued support and encouragement of our stakeholders.
