Alcoa Corporation Provides Update Regarding Wenatchee Smelter in Washington State

Alcoa, a global leader in bauxite, alumina and aluminum products,
announced today that it will make a $62.4 million payment under an
electricity supply agreement for its smelter in Wenatchee, Washington,
and will permanently close one of four potlines at the fully curtailed

In connection with the planned payment on June 19, 2018, and the closure
of the one potline, the Company will record an estimated charge of $73
million (pre- and after-tax), or $0.39 per share, in the second quarter
of 2018.

The payment to the Chelan Public Utility District (Chelan PUD) was
triggered by a recent decision of Alcoa management to not restart the
Wenatchee smelter within the term provided in the amended electricity
supply agreement. Under the agreement, which expires on October 31,
2028, Alcoa receives 26 percent of the electric generation from two
Chelan PUD hydropower projects for the Wenatchee smelter.

During the smelter’s curtailment, Chelan PUD sells unused power on
Alcoa’s behalf, and the proceeds are applied toward Alcoa’s costs under
the agreement. Other than these monthly power transactions, there are no
other required payments.

The potline planned for closure, Line 3 (capacity of 38,000 metric tons
per year), has not operated since 2001, and the investments needed to
restart that line are cost prohibitive. Three other lines at the
Wenatchee site, with 146,000 metric tons per year, have been curtailed
since December 2015. Another line at the Wenatchee site was permanently
closed in 2004.

The closed portions at the Wenatchee site will be evaluated for
potential redevelopment, which will not affect the status of the three
remaining curtailed potlines.
