MINE SAFETY DISCLOSURE

At Alcoa Corporation, management strives to work safely in a manner that protects and promotes the health and well-being of the Company’s employees, contractors, and the communities in which Alcoa Corporation operates because it is fundamentally the right thing to do. Despite uncertainties and economic challenges, Alcoa Corporation remains committed to living its values and managing risks accordingly.

Alcoa Corporation’s health and safety systems are anchored by committed people who are actively engaged and effectively support a safe work environment, safe work methods, and overall production system stability. Each day, people at all levels proactively monitor and intervene to defend against weaknesses that develop in Alcoa Corporation’s safety systems by identifying potential hazards and error-likely situations and responding to eliminate or control them.

In the table below, there are disclosures involving the Point Comfort, TX alumina refinery. All citations have been or are being addressed; none constituted an imminent danger.

Dodd-Frank Act Disclosure of Mine Safety and Health Administration Safety Data

Certain of Alcoa Corporation’s U.S. facilities are subject to regulation by the Mine Safety and Health Administration (MSHA) under the U.S. Federal Mine Safety and Health Act of 1977 (the “Mine Act”). The MSHA inspects these facilities on a regular basis and issues various citations and orders when it believes a violation has occurred under the Mine Act. Whenever the MSHA issues a citation or order, it also generally proposes a civil penalty, or fine, related to the alleged violation. Citations or orders can be contested and appealed, and as part of that process, are often reduced in severity and amount, and are sometimes dismissed.

Management believes the following mine safety disclosures meet the requirements of section 1503(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”).

Mine Safety Data. The table and other data below present mine safety information related to the Company’s U.S. facilities subject to MSHA regulation, as required by section 1503(a)(1) of the Dodd-Frank Act. The following data reflects citations and orders received from the MSHA during the quarter ended March 31, 2018, as reflected in the MSHA system on March 31, 2018, and the proposed penalties received from the MSHA during such period. ($ in full amounts)

During the quarter ended March 31, 2018, Alcoa Corporation had no mining-related fatalities, and none of the Company’s mining operations received written notice from the MSHA of a pattern of, or the potential to have a pattern of, violations of mandatory health or safety standards that are of such nature as could have significantly and substantially contributed to the cause and effect of mine health or safety hazards under section 104(e) of the Mine Act.

The Federal Mine Safety and Health Review Commission (the “Commission”) is an independent adjudicative agency that provides administrative trial and appellate review of legal disputes arising under the Mine Act. As of March 31, 2018, Alcoa Corporation had a total of four matters pending before the Commission. Three of these matters concern contests of citations or orders issued under section 104 of the Mine Act, along with the contests of the proposed penalties for each of these. After a trial, an Administrative Law Judge issued a decision on these three matters on January 18, 2017, for which the U.S. Secretary of Labor has filed a Petition for Discretionary Review. These cases are still pending. The other matter was a retaliation complaint filed by an employee, which was dismissed by an Administrative Law Judge on December 17, 2017, after a trial on the merits. The employee has appealed the dismissal to the Commission, where the matter is pending. All of these matters concern citations, orders or proposed assessments issued by the MSHA during 2015 (three) or 2014 (one).
