Arconic to Freeze Pension Plans for U.S.-Based Salaried and Non-Bargained Hourly Employees

January 8, 2018

Arconic Inc. (NYSE:ARNC) announced today that it will freeze U.S.
defined benefit pension plans for all U.S.-based salaried and
non-bargained hourly employees, effective April 1, 2018.

As a result, in the first quarter of 2018, the Company expects to record
a liability decrease of approximately $140 million related to the
reduction of future benefits and a curtailment charge of approximately
$5 million pre-tax. For the full year 2018, the Company expects
pension-related expense to be lower by approximately $50 million pre-tax
compared to 2017 full-year expenses.

The pension freeze applies to the accrual of future benefits for
approximately 7,900 affected U.S. employees; benefits already earned by
these employees through March 31, 2018 will be available when they reach
retirement eligibility. Retirees already collecting benefits and former
employees with vested benefits under the pension plans will not be
impacted by this change.

Arconic will continue to support affected employees in preparing for a
financially sound retirement by contributing 3% of their eligible
compensation to the Company’s applicable 401(k) plan and by matching
their contributions of up to 6% of eligible compensation to the
applicable plan—consistent with what most new salaried employees
currently receive. Arconic is also providing an additional transition
contribution of 3% of eligible compensation for the remaining nine
months of 2018 for affected employees.

“This transition balances our need to deliver competitive, equitable
benefits to all employees while maintaining market competitiveness,”
said Vas Nair, Executive Vice President of Human Resources at Arconic.

The lower pension expense expectation is based on preliminary year-end
December 31, 2017 results and is inclusive of the change to the pension
plans described above as well as expected changes in other
pension-related assumptions.
