CEMEX ANNOUNCES SIGNIFICANT CORPORATE GOVERNANCE CHANGES

MONTERREY, MEXICO. FEBRUARY 24, 2022 – Continuing its longstanding commitment to evolve its corporate governance towards global best practices, CEMEX, S.A.B. de C.V. (“CEMEX” or the “Company”) today announced a series of significant corporate governance changes.

Beginning with CEMEX’s ordinary general shareholders meeting scheduled to be held on March 24, 2022 (the “Meeting”), each Director candidate will stand for election on an individual basis, meaning that voting at the Meeting will no longer be on a “group slate” basis. Additionally, as part of the Company’s ongoing focus on effective Board structure, a proposal for the Meeting to reduce the size of the Board from 15 to 12 members was presented today. If approved, this will result in the proportion of Board members considered independent under Mexican securities law criteria increasing to 75%. Also, enhanced disclosure concerning the Director candidates, including their qualifications and experience, as well as additional information on Board remuneration, Board and Committee meeting attendance and voting results for the shareholders meetings held in 2021, can be found at CEMEX’s website (www.cemex.com).

“Despite a challenging macro environment, CEMEX has made significant progress in achieving its Operation Resilience goals over the last two years. Importantly, these goals are not just about a fortified capital structure, but they also reposition our company toward sustainable growth with a robust bolt-on investment strategy and an accelerating climate action agenda. All of this leads to a more resilient CEMEX equipped to face the new challenges and social needs of the post pandemic world. With today’s announcement, we are further strengthening the company by continuing to evolve our corporate governance towards global best practices. This effort builds on years of gradual improvements that you should expect to continue over the next few years”, said Rogelio Zambrano, CEMEX’s Chairman of the Board of Directors. “The initiatives announced today, and those expected to come in the future, seek to provide the Company with the oversight on strategy necessary to lead the Company into a rapidly changing future while also providing investors and other stakeholders with greater transparency as we continue to make progress in all aspects of our business.”

The Company also announced that it will be enhancing disclosure in its forthcoming Integrated Report and Annual Report on Form 20-F relating to the responsibilities and practices of the Board and Board Committees, the Company’s executive compensation program, the established process for managing potential conflicts of interests at the Board and executive level and other compliance matters.

Since 2014, the Company has been committed to upgrading its corporate governance practices. These enhancements have included, among others, separating the roles of the Chairman and the Chief Executive Officer, appointing Directors that have increased the representation of independent, female, and international Directors, increasing disclosures regarding shareholders meetings, a Board skills matrix, executive variable compensation, and finally the issuance of an Integrated Report beginning in 2017. The Company will continue to evolve its corporate governance over the next few years through the implementation of formal requirements on electing Board members, Board diversity, independent Board members selection, overboarding, tenure guidelines, and expertise prerequisites, and the way the Board is evaluated, among other changes. Updates on these additional initiatives will be provided as appropriate.

All of the materials for the Meeting are available at the Company’s website (www.cemex.com).
