MATERIAL FACT

Usinas Siderúrgicas de Minas Gerais S.A. - USIMINAS ("Usiminas" or "Company") hereby informs its shareholders and the market in general possible economic and financial impacts arising from the spread of the new coronavirus (COVID-19).

Although the Company has not observed a significant impact on its activities so far, uncertainties regarding the dynamics of evolution of the COVID-19 outbreak and its effects on the economic activity of our clients and suppliers, make impossible to predict the total impact that the pandemic will have on the global economy, as well as on the Company's activities.

However, in view of the already observed global economic downturn, as well as the recent disclosures made by Usiminas clients, especially with regard to the automotive industries, reporting on the decrease and, in some cases, temporary shutdown of its production units, the Company expects a drop in its sales for the coming months, although it is not possible to make concrete estimates in this regard yet.

Usiminas continues to constantly evaluate the impacts on its operations and will keep the market duly informed about future developments, in accordance with the applicable regulation.

Belo Horizonte, March 20th, 2020.

Alberto Ono

Finance and Investors Relations Vice-President Officer
