Ref.: Loma Negra C.I.A.S.A. - Relevant Event

Dear Sirs:

We are writing in order to comply with section 2, Chapter I, Title XII of the Argentine securities regulator (Comisión Nacional de Valores) Rules (2013 revised version).

In this sense, we inform that by resolution of the Board of Directors of Loma Negra C.I.A.S.A. of December 18, 2020 it was approved to renew and reduce the amounts of some of the guarantees granted in favor of the banks with which its subsidiary Ferrosur Roca S.A. (“Ferrosur”) operates . This, in order to guarantee the lines of bank´s overdraft that could be taken by Ferrosur in the ordinary course of its business and letters of credit to finance imports or exports, all for up to a maximum amount of AR$ 900 million. Also, it is informed that as of November 30, 2020, Ferrosur did not maintain significant amounts taken under any overdraft line.

The guarantees will be granted to the extent that Ferrosur effectively takes overdrafts or requests letters of credit with the banks, and for the amounts actually taken in each case up to the maximum limit approved as above mentioned. Each new guaranty will be granted for a period of one year from its granting.

Sincerely,
