In addition to the quarterly meetings, numerous meetings and roadshows were organized virtually - given the coronavirus pandemic - with financial analysts, institutional investors and journalists. Specific meetings and conferences dedicated to ESG (Environment, Social and Governance) issues were also organized, with the participation of the Vice President for Sustainable Development and the Lead independent Director. 2021 was marked by the organization of the Capital Markets Day, a major event for the financial community, which was held on October 6, 2021 in person at the Saint-Gobain Tower, with live broadcasting of the entire event via an immersive platform. This event was an opportunity for the Chief Executive Officer and the management team to present the Group's new strategic plan for the period 2021-2025, the Grow & Impact plan, and to answer questions from the financial community. Those who were able to attend the event in person were able to take part in guided tours of the Saint-Gobain Tower to discover more than 80 Group solutions used in the Tower. The year was also marked by the announcement of two key acquisitions for the Group - Chryso and GCP - which provided an opportunity to present two decisive steps that establish Saint-Gobain as a world leader in construction chemicals and reinforce the Group's strategy as a world leader in sustainable construction. Conference calls with the Chief Executive Officer, the Chief Financial Officer and the Chief Executive Officer of Chryso were held on the day of the announcement of these transactions, along with question and answer sessions. In the context of the coronavirus pandemic and the fight against its spread, and in order to protect everyone's health, the Board of Directors has decided to hold the Shareholders' Meeting in closed session on June 3, 2021, as it did for the June 2020 General Shareholders' Meeting. Shareholders were invited to exercise their voting rights prior to the General Meeting. The Group has ensured that the necessary resources are in place to facilitate remote participation by shareholders, with a full live webcast on the Saint-Gobain website and the possibility for shareholders to ask questions live via the webcast platform. The Group also favored a policy of virtual exchanges with individual shareholders for site visits, meetings and cultural conferences, given the uncertain health environment. The Chief Executive Officer participated in the “Investir Day” event held on November 23, 2021 in a hybrid format (in person and online broadcast). In addition to the virtual events organized throughout the year, the Investor Relations Department kept individual shareholders regularly informed of the Group's many news items via its website, the Saint-Gobain Shareholder app and the Letter to Shareholders. The Saint-Gobain Shareholder app allows shareholders to follow the Group's financial news and find essential and useful information (share price, financial calendar, press releases, etc.). Finally, the Letter to Shareholders, sent twice a year to Group shareholders in March and September, highlights the Group's financial results and strategic priorities.
