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).

We inform that as a result of a labor strike originated in a conflict involving the Argentine Mining Workers Association (Asociación Obrera Minera Argentina - AOMA) and the company contracted by Loma Negra CIASA (the “Company”) for the extraction of limestone in Olavarría -material required for the production of cement- the usual operations in the quarry and the operation of the kilns of the plants in that town were suspended. If the claim is extended in time, it is likely that the Company will be forced to suspend the operation and dispatch from its plants in Olavarría soon.

The Company, together with the company that provides the extraction service, is currently carrying out the actions within its reach in order to resume normal operations in the quarry.

Sincerely,

______________________
