To All Our Shareholders President Thank you for your continuous support of the business of the Komatsu Group. I would like to extend our sincere condolences for all those who have passed away due to COVID-19 as well as to their bereft families, and our sympathy to those who have been infected. I am also sincerely grateful to everyone who has worked tirelessly to maintain our social system, most notably professionals in the medical and health care field. I hereby provide notice of convocation of the 152nd Ordinary General Meeting of Shareholders, which is to be held on June 18, 2021. The Komatsu Group has been executing its business strategy according to the three-year mid-term management plan “DANTOTSU Value – FORWARD Together for Sustainable Growth” since April 2019, under which we are eagerly pursuing three pillars of growth strategies, i.e., 1) value creation by means of innovation, 2) growth strategies based on business reforms, and 3) structural reforms for growth. The business environment in fiscal year 2020 turned out to be challenging due to the slowdown of economic activities affected by the worldwide pandemic of COVID-19, which continues to persist to date. Also, the requirement from society to focus on ESG issues and initiatives to achieve SDGs, among others climate change and carbon neutrality, is intensifying continuously and globally. These conditions surrounding us have made it increasingly important to promote advanced products, services and solutions which create value at our customers’ worksites, while keeping our eyes fixed on the needs of society during and after the pandemic. In order to achieve sustainable growth, we continue dedicating our resources to the activities designated in the mid-term management plan: automation, autonomy (self- supporting), electrification and remote control of construction and mining equipment; the solution business, which optimizes customers’ operations at their worksites; reinforcement of the after-market business through the application of IoT and AI; and products, services and solutions that contribute to environmental protection and a circular economy, such as remanufacturing and the forestry equipment business. Komatsu celebrated its 100th Anniversary on May 13, 2021. I would like to extend our heartfelt gratitude to all stakeholders, including our valued shareholders, for their support to this day. Aiming at continuous growth in the next 100 years, we reiterate our commitment to “quality and reliability,” will create new value through manufacturing and technological innovation, and will strive to realize a future where individuals, society and our planet prosper harmoniously. Finally, I would like to take the opportunity to ask our shareholders for your kind and continuous support.
