Arconic’s Director Slate Brings More Relevant Skills, Leadership Experience and Industry Expertise

Vote “FOR” the Company’s Nominees on the NEW WHITE Proxy Card

The Board of Directors of Arconic (NYSE: ARNC) today issued the below
letter to shareholders in response to the latest letter issued by
Elliott Management (“Elliott”). Additional information, including the
letter to shareholders and supplemental proxy materials, are available
at www.arconic.com/annualmeeting.

The Company urges shareholders to vote “FOR” the Company’s new slate of
five director nominees and governance proposals on the NEW WHITE proxy
card.

The full text of the letter follows:

Dear Fellow Shareholders:

The Arconic 2017 Annual Meeting of Shareholders is fast approaching, and
we are writing to ask you to vote for the slate of director candidates
nominated by the Arconic Board of Directors by using the NEW WHITE proxy
card.

Earlier this week, Elliott Management issued its latest letter in the
ongoing proxy contest, which is essentially a compilation of the same
misleading claims and unfounded allegations that have characterized its
months-long attack on Arconic’s Board and management. Elliott’s most
recent letter really boils down to a simple proposition with three
elements: Arconic has the wrong strategy, real change is needed, and
Elliott’s director nominees offer the best path to real change. Elliott
has advocated each of these three elements with disingenuous rhetoric,
but each is completely wrong.

We urge shareholders to apply their business judgment and experience in
giving Elliott’s assertions a reality check based on the facts and the
specific voting decisions that shareholders will make at Arconic’s 2017
Annual Meeting on May 25, 2017.

First Elliot Assertion: “Arconic Has The Wrong
Business Strategy”

The Board’s strategic view for Arconic is straightforward: we believe
that Arconic will maximize value for shareholders through differentiated
innovation and close strategic partnerships with our key customers.
Arconic seeks to add value in these partnerships and to get paid
appropriately for that value added. We believe this is a higher-return,
long-term industrial strategy than the more commoditized,
build-to-print strategy that Elliott, its nominees and its CEO candidate
have advocated. This type of differentiated, innovation-led strategy is
not novel – many of the best U.S. advanced manufacturing companies have
generated outstanding shareholder returns through this path. We have
concretely illustrated the implications of our strategic view by
publishing a three-year financial plan which includes double-digit
earnings growth and a substantial increase in returns on capital.
Multiple independent research analysts have noted that Arconic’s plan
sets ambitious targets.

If achieved, we believe that this plan’s value creation for shareholders
will be significant. In recruiting a world-class permanent CEO, our
primary focus will be on attracting a leader who agrees that Arconic can
create this type of substantial incremental value for shareholders over
the next few years and over the long term.

Second Elliott Assertion: “Real Change Is
Needed”

To this very misplaced assertion, we answer with the facts: real change
– dramatic, constructive, value-creating change – has been underway for
some time and will continue under your Board and its director nominees.

Your Board has taken or announced a broad range of actions to position
Arconic for success as a new standalone public company, including:

• Intensive work pre-separation to ensure the timely and successful
  launch of both Arconic and Alcoa Corp. as separate companies in
  November 2016.
• Substantial refreshment of the Board itself (seven of the 11 directors
  currently serving on the Board have joined within the past 16 months).
• Initiating a wide range of governance enhancements, including the
  formation of a Finance Committee, focused on optimizing capital
  allocation, and the adoption of proxy access.
• Streamlining our executive compensation program to align it with core
  metrics (such as RONA, margin improvement and earnings growth) that
  directly drive improved shareholder value.

Your Board is committed to aggressively driving constructive change that
creates shareholder value – both near- and longer-term – and has
demonstrated that it has zero interest in sitting still, “entrenching”
itself or any other Elliott-asserted clichés that fly in the face of the
reality at Arconic.

Third Elliott Assertion: “Elliott Nominees
Offer The Best Path to Real Change”

The fact is that both Arconic’s slate and Elliott’s slate consist only
of directors who are or will be new to Arconic within the past 16
months. Notwithstanding Elliott’s focus on the past, the only decision
being contested at the 2017 Annual Meeting is the vote between Arconic’s
director nominees and Elliott’s director nominees. We welcome a detailed
review by shareholders of the two slates, because we believe the Arconic
slate brings far more relevant skills, leadership experience and global
aerospace-industry expertise. Our nominees include:

• Arconic’s Interim CEO, who previously ran a $15 billion global
  commercial and military aircraft engine company, and a major Arconic
  customer.
• Arconic’s Audit Committee Chair, who previously served as CFO of two
  different aerospace suppliers, and who was nominated by Elliott in
  2016.
• Arconic’s Cybersecurity Subcommittee Chair, an aerospace engineer and
  innovation expert who serves as the Board’s cybersecurity expert.
• The former head of Boeing’s Commercial Airplanes business and, prior
  to that, leader of Boeing’s Integrated Defense Systems business.
• The first female four-star general in U.S. Air Force history, who was
  responsible for procurement for the U.S. Air Force and oversaw a
  significant restructuring of the Air Force Materiel Command to improve
  efficiency.

We believe that all of Arconic’s nominees are exceptionally
well-qualified and bring the critical skills and experience needed to
drive further constructive change at Arconic and value creation for its
shareholders.

Without the facts on its side, Elliott has resorted to its well-worn
playbook of distortions and diversions. Consider just a few examples of
how Elliott’s claims compare to the facts:

					Elliott Claim			The Facts
					“[T]he Board is involved. But Elliott is committed.”   “Elliott’s focus is very much long-term oriented.”			Arconic’s directors have real commitments – in the form of fiduciary duties – to the Company’s shareholders. Elliott, by contrast, has no commitment to Arconic’s other shareholders, and no commitment to the long-term success of the Company. While Elliott is indeed a significant shareholder and has an economic interest in Arconic, it has made no commitment to maintain its shareholding for any period of time. In fact, during settlement negotiations, Elliott insisted on having the unfettered ability to sell its shares at any time , demanding that Arconic file a registration statement to facilitate its sales.
					Elliott is engaging in “responsible” and “constructive” activism.   Elliott’s proxy contest “is a last resort, not a preferred course.”			Elliott has spent the last 15 weeks running one of the most aggressive campaigns of personal destruction the capital markets have witnessed , seeking to humiliate and destroy Arconic’s former CEO, and now its directors, to win at any cost. And Elliott has twice reneged on settlement agreements and insisted on continuing its proxy contest even after its principal objective (a change in Arconic’s CEO) occurred, and even after the Board made a reasonable proposal to appoint two of Elliott’s director nominees, which Elliott promptly rejected.
					The Board has engaged in a “determined defense for years” of its legacy governance regime.			Arconic, and Alcoa before it, have spent years pursuing governance reforms, including implementing proxy access, enhancing the Company’s executive compensation programs and submitting past proposals to declassify the Board and eliminate supermajority provisions. The reality is that Arconic has been saddled with legacy supermajority voting requirements that limit the Board’s ability to make desirable governance changes.   Moreover, the Board has made clear that it will provide for all directors to be subject to annual elections beginning in 2018 , and if the governance proposals are not approved at the 2017 Annual Meeting, Arconic intends to pursue reincorporation as soon as practical . The Board decided not to pursue reincorporation while the separation was pending because it could have seriously jeopardized the timing of the separation (particularly if pro forma financial statements would have been required by the Securities and Exchange Commission). The Board also considered whether it would be feasible to submit a reincorporation proposal at the upcoming annual meeting, but the need for a merger proxy statement could have resulted in a longer SEC review process for Arconic’s proxy materials and therefore substantially impacted its ability to compete with Elliott for shareholder support in the proxy contest.   In any event, none of Arconic’s nominees have been on the Board “for years.” They represent just as much change as Elliott’s nominees.
					The “shareholder-friendly corporate governance practices” of Alcoa Corp. provide a basis to criticize Arconic’s governance.			Alcoa Corp., which, like Arconic, launched in November 2016, is incorporated in Delaware and has annual director elections. It was the Alcoa Inc. directors, seven of whom now serve on the Arconic Board, that created these Alcoa Corp. governance features, in keeping with the Board’s commitment to corporate governance best practices . Pat Russo, Arconic’s current interim Chair, was the chair of Alcoa Inc.’s governance and nominating committee and accordingly played a critical role in determining the corporate governance profile of Alcoa Corp.
					Arconic is seeking to limit its next CEO’s “freedom to operate” and will “tie[] any new CEO’s hands.”			Arconic has begun the process of selecting a world-class candidate to serve as the new CEO, and the Board is committed to ensuring that Arconic’s next leader has the appropriate authority and role in the Company’s operations, financial planning and business strategy. The Board resisted Elliott’s attempt to impose an “Operations Committee,” consisting of a majority of Elliott’s designated nominees and with a mandate dictated by Elliott, because it could seriously undermine Arconic’s efforts to recruit the best possible CEO . CEO candidates may be unlikely to sign up for micromanagement by a Board committee with an agenda delineated by one shareholder.
					“[T]he Board had no credible succession strategy.”			Elliott has manufactured a claim about inadequate succession planning because it cannot attack the appointment of David Hess as Arconic’s highly qualified interim CEO . Mr. Hess has been a stabilizing force during this period of transition. Moreover, considerable succession-planning efforts were recently required for the separation of Alcoa Inc. into Arconic and Alcoa Corp., which involved the recruitment or promotion of several executive candidates in order to ensure both companies had top-notch, experienced management teams, including an executive ready to lead a large public company, like Alcoa Corp.
					The Board has inappropriately “rewarded” the interim Chair with “an immediate eight-fold increase in compensation.”			Elliott’s math is wrong and grossly overstates the interim increase in Ms. Russo’s total director compensation.
					Arconic should be criticized for “the returns which have been earned on [its] investments.”			Elliott has focused on historical Alcoa Inc. returns that were impacted by pre-2008 capital commitments in the upstream business combined with the low commodity price environment. In fact, a substantial increase in Return On Net Assets has been achieved in Arconic’s businesses, and Arconic has implemented an exacting capital expenditure approval process with strict growth investment criteria .
					“[C]hange is not simply about bringing in new people.”			The Board has brought in new directors and nominees – nine in the last 16 months. But Arconic’s changes have not been only about directors; it has also shed businesses, acquired others, split the company to create two independent firms, made a swift and decisive change in leadership and implemented a revised executive compensation program aligned to value creation specific to Arconic’s business .
					Shareholders should not be concerned about Elliott’s ever-increasing demands at Arconic because it “hasn’t nominated any employee or affiliate” and its nominees “will receive no ongoing compensation from Elliott.”			The Board is charged with acting on behalf of all shareholders, and having one 13% shareholder designate a majority of the Board and direct the selection of the new CEO is not consistent with good governance that serves the best interests of all shareholders . While its nominees may not be on its payroll, Elliott has failed to mention that it has proposed a CEO candidate who it has agreed to pay approximately $28 million over the course of the next two years .
					The Arconic Board has triggered a “poison put” whose “sole plausible purpose is to entrench management and the Board” despite having “the right to unilaterally amend or eliminate the provision at any time it wanted.”			Arconic’s rabbi trust is not a poison put – no liabilities have been created, accelerated or increased as a result of the Board’s determination. And the rabbi trust has nothing to do with entrenchment – its sole purpose is to set aside funds to protect the Company’s pre-existing benefit obligations to its employees and retirees, which are already reflected on Arconic’s balance sheet , from mismanagement following a change in control. In fact, a court recently found “no evidence” that the Arconic rabbi trust was “chilling the votes of any of the shareholders.” After Elliott launched its proxy contest, management identified the potential change in control trigger in the trust agreement and, promptly after this was brought to the Board’s attention, the Board took action to ensure full disclosure of the trust agreement. Moreover, Elliott’s claim that Arconic had a clear right to amend the trust agreement at any time is false.
					Arconic engaged in “vote-buying” and “fail[ed] to make proper disclosure” of the voting commitment entered into with Oak Hill in August 2016 to “tamper with the shareholder franchise.”			The voting commitment was not “bought” because no additional value was given by Arconic for it. The Oak Hill agreement was not filed because it was not material and contained customary confidentiality restrictions which continue to prohibit public disclosure.   Elliott conveniently fails to mention that it has entered into numerous voting commitments – including as part of Alcoa Inc.’s settlement agreement with Elliott last year.   Most importantly, in the context of the current proxy contest, the Board determined to waive the voting commitment promptly after it became aware of it, in order to enable full participation by every shareholder in the contested election .

Despite Elliott’s best efforts to paint a picture of a company in
trouble and a Board in need of change, the image they have created does
not bear any semblance to the reality at Arconic. Your Board has
initiated a number of changes – both in the Company itself and in its
own composition. We have recently completed a successful separation
transaction and strong first quarter as an independent company, and a
majority of our directors are nearly brand new to the Company. Your
Board is unanimous in opposing Elliott’s campaign and believes Elliott’s
suggestions are misleading and would jeopardize the value of your
investment in Arconic.

We ask that you join us in looking to the future, and
vote
on the NEW WHITE card for the Board’s recommended nominees
,
who we believe are the most qualified candidates for election at the
2017 Annual Meeting and who will bring the right kind of change to
Arconic.

Unanimously,

The Board of Directors of Arconic Inc.
