May 10, 2017
Dear Fellow Shareholder:
      At Arconic’s upcoming Annual Meeting of Shareholders on May 25, 2017,
      you will have the opportunity to elect five director candidates
      nominated by Arconic who we believe bring new perspectives, critical
      skills and a wealth of relevant expertise to Arconic’s Board of
      Directors.
    
      Three of our candidates are current Board members – none having served
      for more than 16 months – and two are entirely new and have not yet
      served on Arconic’s Board.
    
      We invite you to hear from the Arconic Director nominees to learn a
      little more about their personal views and their objectives regarding
      Arconic.
    
Unanimously,
The Board of Directors of Arconic Inc.
      
David P. Hess, Interim CEO
Director since: March
      2017
    
Unique Qualifications:
- Proven aerospace industry leader, with 38 years of industry experience
 - 
        Known for extensive and credible customer relationships across the
industry - 
        Former EVP and Chief Customer Officer for Aerospace at United
Technologies Corp.; Former President of Pratt & Whitney 
      You are Arconic’s newest director and were recently appointed Interim
      CEO. What has impressed you most about the Company? What do you see as
      its greatest challenge?
    
      I’ve been impressed by how thoroughly engaged and open-minded this Board
      is, as well as the range and balance of perspectives that the directors
      collectively bring to bear in our deliberations. Although I’ve only been
      on the Board for a little over two months, we’ve had numerous board
      sessions and frequent interactions. This has given me a good opportunity
      to see the group make some critical decisions and tackle tough issues –
      including addressing an inappropriate letter sent by our former CEO,
      recruiting new nominees to fill two open Board seats, contemplating the
      appropriate timing for the annual meeting in light of fast-changing
      circumstances, and engaging in settlement discussions with Elliott. I
      believe if you were in the boardroom along with us, you would observe a
      group of people who always act with the highest ethics and integrity and
      always with the best interests of the shareholder in mind.
    
      In terms of challenges going forward, perhaps the most critical task for
      Arconic right now is recruiting a new CEO. We’ve formed a search
      committee and are starting a deliberate and thorough process to select
      the perfect candidate with the right experience and capabilities to lead
      Arconic into the future. At the same time, we must remain relentlessly
      focused on meeting or exceeding the expectations of our customers and
      shareholders and on flawlessly executing our three-year plan. I am truly
      honored to serve as your interim CEO and to be able to lead Arconic
      through this challenging period. In the short time that I’ve been here
      at Arconic, I have been very impressed by the dedication of our
      employees and the support of our customers. With a strong first quarter,
      we’re off to a great start, and I look forward to what lies ahead.
    
      
James “Jim” F. Albaugh
New Nominee, to join at
      2017 Annual Meeting
    
Unique Qualifications:
- Internationally recognized commercial aerospace executive
 - 
        Former President and CEO, Boeing Commercial Airplanes; Former Member
of Boeing’s Executive Council - 
        Currently, independent director of American Airlines and Harris
Corporation - 
        Currently, Chairman of the National Aeronautic Association; Past
President of the American Institute of Aeronautics and Astronautics;
Past Chairman of the Aerospace Industries Association 
      Why did you decide to join the new Arconic slate when it is in the
      middle of a proxy fight? You must have numerous other opportunities to
      serve on public company boards.
    
      I agreed to join the slate because I believe Arconic is an outstanding
      company with a strong values-based culture. As the President and CEO of
      Boeing’s Commercial Airplanes business, I experienced first-hand what it
      means to be one of Arconic’s customers. The Company stood out to me as a
      true partner that invests in growing areas and innovative technologies,
      and I believe the reputation and culture that Arconic has built up over
      time gives it a strong foundation for future growth.
    
      In addition, as a newly launched, standalone company, Arconic now has a
      more streamlined set of businesses with a strong focus on the aerospace
      and transportation industries. Given my background, this felt like an
      ideal opportunity for me to contribute my knowledge and expertise to a
      company where it is directly relevant and hopefully will have a real
      impact. I spent almost my entire career in the aerospace sector, and my
      perspective has been shaped not only by my years at Boeing but also as
      Chairman of the National Aeronautic Association and in my prior roles as
      President of the American Institute of Aeronautic and Astronautics and
      Chairman of the Aerospace Industries Association. I’ve had the
      opportunity to discuss the future of the commercial aerospace industry
      with a number of leaders, and I’m excited to help Arconic realize its
      full potential.
    
      
Amy E. Alving
Director since: November 2016
Committees:
      Audit Committee; Cybersecurity Advisory Subcommittee (Chair)
    
Unique Qualifications:
- In depth technology, defense, and engineering expertise
 - PhD in Mechanical & Aerospace Engineering
 - Successful public company board track record
 
      You are new to the Board, having joined last November upon the launch
      of Arconic as a standalone company, following its separation from Alcoa
      Corp. What is it like to be part of a company going through so much
      change?
    
      We do have a lot of change underway – governance changes at the Board
      and CEO level, and operational changes as we are able to focus on our
      core business, post-separation. From my experience on other boards I
      know that, when making tough decisions, access to a diverse set of views
      is key to finding the best path. This Board was carefully constructed to
      include a wide range of experiences and perspectives. Arconic’s Board is
      a bit unique in that seven of us have joined in the past 16 months, and
      we are fortunate to benefit from the knowledge of the four directors
      with longer tenure.
    
      Personally, I am especially attracted to Arconic’s emphasis on
      technology and innovation, which have been the focus of my career. I
      served as the Director of the Special Projects Office at the Defense
      Advanced Research Projects Agency (DARPA), where we developed
      breakthrough innovations in support of national security. Later I was
      the Chief Technology Officer at one of the nation’s largest defense
      contractors. I know that successful innovation at a large company
      requires alignment from the boardroom through management to the
      front-line technologists, and it requires close, iterative collaboration
      with customers to ensure appropriate return on investment.
    
      From my experience in the defense and financial services sector, I also
      understand the evolving cyber security threat that Arconic is facing. As
      Arconic increases its criticality in the national-security supply chain,
      its Board will need to ensure the Company stays ahead of this threat.
    
      
Ulrich R. Schmidt
Director since: February 2016
Committees:
      Audit Committee (Chair); Executive Committee; Governance and
      Nominating Committee; Finance Committee
    
Unique Qualifications:
- Extensive executive and business experience at the board and CFO level
 - 
        Deep knowledge of the aerospace industry, including as Former EVP and
CFO of Spirit Aerosystems Holdings, Inc. and separately, Goodrich
Corporation - Served as chairman of Precision Castparts Audit Committee
 
      You were suggested for the Arconic Board by Elliott last year – how
      has your integration into the Board gone? Elliott obviously has
      confidence in your judgment and perspective as a director (it is not
      contesting your election this year) – with that in mind, do you feel
      that Elliott’s criticisms of the Board are warranted?
    
      Following my appointment to the Board, together with the other two
      directors who were also nominated by Elliott last year, it was
      immediately apparent that everyone on the Board has a voice and their
      views are respected. Our meetings are characterized by open debate, a
      free flow of ideas and the shared goal of doing what is right for the
      Company and the shareholders. So to answer your first question, the
      integration was seamless and there was no “us versus them” mentality or
      other tension between the Elliott nominees and the rest of the Board.
    
      Regarding your second question – I don’t believe Elliott’s criticisms of
      the Board and its culture are supported by the facts. I have found that
      the Board is thoroughly engaged, values strong governance and the
      highest standards of ethical behavior, and actively evaluates and
      embraces changes that it believes make sense for the Company and are in
      the best interests of all constituents. Many of the governance changes
      that have recently been adopted were being contemplated prior to or in
      connection with the separation, well before Elliott launched its proxy
      fight.
    
      
Janet C. Wolfenbarger
New Nominee, to join at
      2017 Annual Meeting
    
Unique Qualifications:
- 
        In depth defense knowledge; 35-year veteran and first female four-star
general of U.S. Air Force - 
        Former lead procurement officer for U.S. Air Force, a major Arconic
customer - Independent director of AECOM since August 2015
 
      As the Air Force’s first female four-star general, what makes you
      want to take on the challenge of serving on the Arconic Board?
    
      I’ve been fortunate to serve with exceptional teams throughout my
      career, both in the Air Force and post retirement, in my corporate board
      and federal advisory committee work, and I’ve been impressed with the
      caliber of the people who serve at Arconic.
    
      During my 35-year tenure in the U.S. Air Force, I oversaw an
      approximately $60 billion annual budget, including purchasing, which
      covered a large portion of the approximately $1 billion of business that
      Arconic does in the defense industry. Arconic operates in an important
      and very competitive industry, and it stands out to me as a leader in
      the space. Not only because the Company offers leading innovative
      technologies, but also because Arconic puts in the effort to maintain a
      dialogue with its customers in order to better understand and adapt to
      their wants and needs.
    
      I also have experienced firsthand the complexities that surround
      organizational transformations, which I feel gives me some insight into
      Arconic – itself the product of a transformation that is still underway.
      I understand that an ongoing commitment to excellence, efficiency, and
      cost effectiveness is integral to any organization’s success,
      particularly in the early years, and feel Arconic’s strategy of focusing
      its efforts on high-potential areas reflects that.
