Corporate governance Compensation of the management and governing bodies

Gouvernance changes in 2021 In view of the changes in governance in 2021: the Executive corporate officers compensation for the ■ 2021 fiscal year has been annualized; the compensation ratios of all Executive corporate ■ officers over the last five years are presented. Employees taken into account Only the employees who have entered into an indefinite or fixed-term employment contract with Compagnie de Saint-Gobain or a consolidated subsidiary of the Saint-Gobain Group registered in France and who have been continuously employed in these companies from January 1 to December 31 of the fiscal year in question were taken into account when calculating the ratios. The employees who have entered into a part-time employment contract with Compagnie de Saint-Gobain or a consolidated subsidiary of the Saint-Gobain Group registered in France were not taken into account when calculating the ratios but represent less than 3% of the workforce on the considered perimeter. Concept of full time equivalent To determine the average and median compensation paid to employees of Compagnie de Saint-Gobain and the consolidated subsidiaries of the Saint-Gobain Group registered in France on a full-time equivalent basis, the methodologies already in use within the Group for the employee data reporting reviewed by the independent third party in charge of reviewing extrafinancial information were used (see Chapter 9, Section 2.1). Changes in scope Within the French perimeter, the consolidated companies sold during a given fiscal year are excluded from the ratios calculations of that fiscal year. The acquired companies which were in the process of being consolidated on December 31, 2020 are excluded from the ratios calculations, but represent less than 1% of the total number of employees of the consolidated subsidiaries of the Saint-Gobain Group registered in France. The compensation of Executive corporate officers for fiscal years 2019 and 2020 taken into account for the calculation of the compensation ratios for 2019 and 2020 were impacted by the reductions of 25% of their fixed compensation for 2020 and 25% of their variable compensation for 2019 (see Chapter 5, Section 2.2.2 of the Company's 2020 universal registration document) decided by the Board of Directors for as long as the Group’s employees were subject to partial employment in the context of the emergency measures taken by the French Government to halt the spread of the Covid-19 pandemic. Compensation paid by the French State in 2020 to employees of Saint-Gobain Group entities subject to partial employment in the context of the emergency measures taken by the French Government to halt the spread of the Covid-19 pandemic are taken into account for the purposes of calculating compensation ratios for 2020 as if that compensation had been paid by the Saint-Gobain Group. Covid-19 effect on the calculation of compensation ratios in 2019 and 2020

The difference between the ratios on Compagnie de Saint-Gobain’s average compensation and on average compensation in France is mainly due to the distribution structure of the employees in the scopes concerned: thus, while in 2021, Compagnie de Saint-Gobain comprised 82% of managers (including all members of the Executive Committee of the Saint-Gobain Group except those based in a foreign country) and 18% of administrative employees, the French scope comprised 23% of managers, 53% of administrative employees and 24% of blue-collar workers. Method used to calculate compensation ratios To calculate the compensation ratios presented above, Compagnie de Saint-Gobain referred to the guidelines on compensation multiples published by the AFEP on January 28, 2020, updated in February 2021. The compensation components and the methodology selected are shown below. Compensation components selected For Executive corporate officers: all compensation paid or awarded during or for the fiscal year in question, submitted to the vote of the General Shareholders’ Meeting (Say on Pay ex post ) (1) , namely: the fixed compensation paid during the given fiscal ■ year; the annual variable compensation granted in respect of ■ the same fiscal year; any exceptional compensation paid during the same ■ fiscal year; long-term compensation instruments granted during ■ the same fiscal year (stock options, performance shares and/or performance units) at IFRS value on the grant date; benefits in kind (company car) granted during the same ■ fiscal year (book value); it being specified that Executive corporate officers are ■ not granted any compensation in respect of their Directors’ term of office within the Saint-Gobain Group. For employees: the fixed gross compensation paid during the given ■ fiscal year; for reasons of information availability on the publication ■ date of the Universal Registration Document, the annual gross variable (annual bonus, profit-sharing, incentive schemes, payments into the Group Savings Plan, as applicable) and exceptional (premiums) compensation paid during the same fiscal year; long-term compensation instruments granted during ■ the same fiscal year (stock options, performance shares and/or performance units) at IFRS value on the grant date; benefits in kind granted during the same fiscal year ■ (book value); to ensure consistency with the compensation ■ components paid to the Executive corporate officers, termination of office indemnities are not included.
