Resolution to End Proxy Contest: Five Things to Know

1. Arconic has entered into an agreement with Elliott Management to resolve the pending proxy contest in connection with the Company’s May 25, 2017 annual meeting of shareholders.

2. Under terms of the agreement, Elliott will nominate Christopher L. Ayers, Elmer L. Doty and Patrice E. Merrin, and Arconic will nominate David P. Hess and Ulrich R. Schmidt for election as directors at the upcoming annual meeting. Elliott and Arconic have agreed to withdraw their respective nominations of any other director candidates.

3. One of Elliott’s director nominees will be added to the CEO search committee and Elliott will have the opportunity to engage collaboratively with the CEO search committee and meet with candidates as the Board manages the search and selection process. The mandate of the CEO search committee is to identify a world-class leader for Arconic. It will consider a number of candidates, including Larry Lawson.

4. L. Rafael Reif, an Arconic director since 2015, has announced his resignation as a Board member; the Board appointed James “Jim” F. Albaugh, a candidate previously nominated by Arconic for election at the annual meeting, to fill the resulting vacancy effective immediately following the 2017 annual meeting.

5. Arconic will be working to reincorporate in Delaware by the end of this year, and the certificate of incorporation and bylaws of the resulting Delaware corporation will provide for an annually elected Board and contain no provisions requiring a supermajority shareholder vote.

• Elliott is nominating Christopher L. Ayers, Elmer L. Doty and Patrice E. Merrin.

• Arconic is nominating Ulrich “Rick” R. Schmidt and David P. Hess.

2. If you previously voted, your latest proxy card will be voted as you instructed for those nominees who remain. Votes for withdrawn nominees will be disregarded. You do not need to revote.

3. If you have not yet voted, please do so, noting the fast-approaching deadline for your proxy card in advance of the Annual Meeting on May 25. The Arconic Board continues to recommend that you vote on the white proxy card.

FAQs

What happens to the other nominees— Bernd F. Kessler on Elliott’s blue proxy card, and Amy E. Alving, James F. Albaugh and Janet C. Wolfenbarger on Arconic’s white proxy card?

The nominations of those candidates have been withdrawn. Any votes for those candidates will be disregarded, while proxy cards will be voted as instructed with respect to the remaining nominees.

What if some candidates don’t receive as many votes as others?

With five nominations for five open Board seats, the five candidates are uncontested.

May I split my vote, submitting both blue and white proxy cards?

No, if a shareholder submits multiple proxy cards, only the latest dated card counts. The Arconic Board continues to recommend you vote on the white proxy card.

The voting deadline for my shares is fast approaching. How do I ensure my vote is counted?

Your proxy card includes details on how to vote by web or phone, using your individual control number. These options are available 24x7 through the voting deadline and authorizes the named proxies to vote your shares in the same manner as if you had marked, signed and returned a physical card.

The voting deadline for my shares is already past. What options do I have to vote?

If voting for your shares has closed, your latest vote cast will be voted as instructed with respect to the remaining nominees. Any votes for withdrawn candidates will be disregarded.

Does my vote really matter?

Yes, even with five nominations for five open Board seats, it is important that you vote to ensure enough votes are received, and to get your vote on the corporate governance proposals related to supermajority voting, executive compensation, and the independent public accounting firm.

Arconic’s interim Chief Executive Officer David P. Hess sent the following employee communication:

Agreement Reached, Ending Proxy Contest

Arconic Team,

This morning we announced that Arconic and Elliott Management have reached an agreement to end the proxy contest.

As part of that agreement, Elliott will nominate Christopher L. Ayers, Elmer L. Doty and Patrice E. Merrin for election as directors at the upcoming annual meeting, and Arconic will nominate Rick Schmidt and myself. Both Elliott and Arconic have agreed to withdraw their nominations of any other director candidates, so there are now five nominees for the five seats up for election. More details about the settlement are in this press release.    See details about voting.

In addition, L. Rafael Reif has resigned from the Board and will be replaced by James “Jim” Albaugh, effective immediately following the annual meeting.

Now that the proxy fight is over, the Board’s highest priority will be to appoint a world-class permanent CEO to lead Arconic. I am proud to continue to serve as your interim CEO while the Board conducts its search. I only recently joined Arconic, but I’ve admired this company for a long time. While serving in leadership roles for United Technologies and Pratt & Whitney, I saw the strength of Arconic first-hand, including world-renowned R&D capabilities, lean manufacturing know-how, incredible talent and strong values.

With the proxy contest behind us we can now all get back to business. You built a great company and launched it with the slogan “Innovation, Engineered.” To me those aren’t just words. Their meaning is real for all of our customers. Technological leadership, combined with a continued focus on cost reduction and operational excellence remain at the forefront of what we do.

Over the past few months, many viewpoints were shared. Through it all, you remained steadfast in your focus and delivered a strong first quarter. The Board and I appreciate your efforts. It is critically important we continue to deliver for our customers and shareholders, while keeping safety as our top priority. Thank you for your continued commitment.

Sincerely,

David

David Hess

Interim CEO
