MATERIAL FACT

Braskem S.A. ("Braskem" or "Company"), in compliance with CVM Instruction 358/02, informs its shareholders and the market that, it became aware of a letter from the National Mining Agency (“ANM”) regarding measures for the closure of salt extraction activities in Maceió with the closure of the mine including the backfilling with solid material of a number of additional salt wells (“Letter”).

As already informed in other opportunities, the Company has been implementing actions consisting in backfilling 4 salt wells with solid material, a process that should take three years, and in actions of conventional closure and monitoring for the remaining salts wells of the Company. These actions were defined based on the recommendations of studies carried out by independent institutions and renowned experts nationally and internationally, and which have been shared with ANM.

For the implementation of the measures defined by ANM in the Letter and taking into account the preliminary information that the Company obtained to date and without the benefit of discussions with ANM, the Company estimates approximately R$3 billion in costs and expenses in addition to the amounts already booked. Such incremental costs and expenses, if confirmed, would be incurred in the long term due to the complexity of the technical aspects. The Company´s actual costs may be materially different than this preliminary estimate based on a variety of factors, including but not limited to the result of the monitoring and backfilling actions of the wells, potential future determinations by ANM, unforeseen technical difficulties or costs, or other factors. Additionally, the Agency may reevaluate the measures presented in the Letter, including dispensing with backfilling remaining wells in the event of soil stabilization.

Lastly, the Company informs that it will engage in discussions with the ANM regarding the measures defined in the Letter.

To the extent required by applicable law, the Company will keep the market informed of material developments concerning the geological event in Alagoas and related proceedings, which include the public-interest civil action filed by the Federal Prosecution Office involving social and environmental damages, as well as negotiations with other authorities related to the geological event in Alagoas. The Company cannot predict with certainty future developments in respect of this matter or its related expenses, and the costs to be incurred by the Company may be different than currently estimated.
