The Cosmo Energy Group states in chapter 1 of its Code of Conduct, “We are determined to be a safe, accident-free corporate group.” It is our mission to ensure safety and confidence in all business activities. Based on the Group Management Vision and the Code of Conduct, we established the Safety Policy to guide our basic approach to safety.
The Cosmo Energy Group has designated “safe operations and stable supply” as one of its most important material issues with an impact on enterprise value over the medium to long term. We have incorporated “safe operations and stable supply” into our governance categories as the foundation for enhancing enterprise value, and we are establishing targets and KPIs for these categories.
Cosmo Energy Group’s Safety Management System
The Cosmo Energy Group promotes safety management efforts in Group-wide business activities based on a strong sense of its mission to realize a stable energy supply. We work to ensure safe operations and stable supply by striving to eliminate accidents and work-related injuries at our business sites and departments.
Under the Seventh Consolidated Medium-Term Management Plan (FY2023 – FY2025), we focused on “safe operations and stable supply” as a priority, and we are taking safety measures throughout the entire Cosmo Energy Group. Moving forward, we will continue to strive to strengthen our safety management system and raise safety awareness throughout the Group under the eighth Consolidated Medium-Term Management Plan.
Results of Seventh Consolidated Medium-Term Management Plan Initiatives
The Cosmo Energy Group promoted initiatives on safety management and risk management activities via the Sustainability Strategy Council with the aim of ensuring safety and reducing future risk in Group-wide business activities, seeking in all of these efforts to earn greater social trust and confidence.

Initiatives on Safety Measures
At the Cosmo Energy Group’s business sites, including refineries and plants, we have set the safety goal of zero serious accidents (fires, explosions, external leaks, large-scale leaks, and serious work-related injuries), and we are focused on a variety of safety measures. In addition, we implement safety management by establishing management targets as indicators, and we foster a culture of safety by improving workplaces and working environments and applying our Operational Management System (OMS).
In fiscal 2025, the Cosmo Energy Group achieved zero serious workplace accidents. We will continue to strictly enforce our basic guidelines and rules to maintain this record of zero serious workplace accidents.

Initiatives to Prevent Accidents Being Forgotten and to Reduce Unsafe Conditions
Cosmo Oil has designated March 11, the date when an LPG fire and explosion occurred during the Great East Japan Earthquake, as Cosmo Oil Safety Day. Group employees watch a video compiling the story of the accident, its cause, and steps taken to prevent a recurrence. We continue to work never to forget the incident by implementing initiatives such as safety seminars in various regions. In fiscal 2024, we invited an external expert to speak at a seminar, which offered a valuable opportunity to reassess the importance of safe operations.
More than ten years since the accident, we are ensuring that information about the accident is passed on to a new generation of employees who did not experience it. We are also grateful once more for the cooperation and support of local residents, neighboring companies and relevant government authorities, which has enabled us to continue our operations, and we will continue to keep safety as our top priority.

Initiatives to Ensure Safe Operations and a Stable Supply
In addition, our major group companies other than Cosmo Oil Co., Ltd. are also promoting the following initiatives to ensure safe operations and a stable supply.
Maruzen Petrochemical Co., Ltd.
Maruzen Petrochemical’s advanced safety management system has been recognized, leading to the Chiba Plant obtaining Special Accredited Advanced Safety Inspector Certification (A-Certification) in February 2025, and the Yokkaichi Plant obtaining certification as an Advanced Self-Regulatory Safety Operator in March 2026. Furthermore, through the strengthening of disaster prevention systems, training, risk assessments, and patrols, we aim to maintain accident- and disaster-free operations.

Cosmo Oil Marketing Co., Ltd.
We have long been promoting initiatives aimed at reducing accidents and incidents related to the overland transportation of petroleum products to customers, including service stations. Specifically, we have established key performance indicators focused on preventing traffic accidents during transport and contamination incidents (where the wrong petroleum product is mixed in) during unloading, as well as reducing damage at delivery facilities. We are engaged in safety initiatives in collaboration with transport companies and delivery destinations, including facility improvement activities at delivery sites, awareness activities promoting on-site supervision during unloading, and the introduction of systems to prevent mis deliveries and collision-avoidance devices.
