CEMEX, S.A.B. de C.V. (“CEMEX”) (NYSE: CX) today informed the Mexican Stock Exchange (Bolsa Mexicana de Valores) of a message sent by the CEO of CEMEX to CEMEX’S worldwide employees announcing further measures designed to mitigate the impact of the COVID-19 pandemic and to strengthen CEMEX’s liquidity position.

CEMEX believes the world is going through an unprecedented time due to the COVID-19 pandemic and that CEMEX’s industry and CEMEX are no exception. CEMEX expects that construction activity across most of the markets in which CEMEX operates will be impacted for some time, before returning to pre-pandemic (COVID-19) levels.

CEMEX also believes that it is crucial that it responds in an agile manner to this health crisis, focusing its efforts on the variables CEMEX can control. CEMEX’s focus during these challenging times is on three priorities: first, to protect the health and safety of its employees and their families, customers, and communities; second, to support its customers as much as possible in a responsible way; and third, to take decisions that protect the future of CEMEX.

In the past few weeks, CEMEX has applied strict hygiene protocols in all its operations and modified its manufacturing, sales, and delivery processes to implement physical distancing intended to considerably reduce the possibility of contagion of COVID-19. CEMEX has also strengthened its liquidity position, mainly with funds from its committed revolving credit facility and with proceeds from asset sales.

As a further measure to enhancing CEMEX’s liquidity, CEMEX is suspending its share repurchase program for the remainder of the year and, as previously informed, is not paying dividends during 2020.

In addition, CEMEX shall undertake the following temporary measures that CEMEX believes could save jobs, weather the crisis, and allow CEMEX to recover as soon as possible. Starting May 1st, 2020 and for a 90-day period, in accordance with applicable laws and regulations:

Also, with immediate effect, and for the next 90-days, CEMEX will suspend or reduce the following:

During the next three months, CEMEX plans to focus all its efforts on managing the impact of the COVID-19 pandemic on its production, commercial, and financial activities. CEMEX will continue to carefully monitor this overall situation and expects to take additional steps, as could be required.
