Full story

Arconic Adds Two Exceptional Director Nominees, Issues New White Proxy Card

The Arconic Board of Directors published an open letter to Arconic shareholders and published a new investor presentation. Here’s what employees need to know:

1. Arconic has added two exceptional candidates to its slate of Board of Director nominees. They bring valuable aerospace expertise to an already outstanding director slate dedicated to serving shareholder interests.

• Our new nominees are:

• James “Jim” F. Albaugh, an internationally recognized aerospace executive who was the President and Chief Executive Officer of Boeing Commercial Airplanes until his retirement in 2012. Prior to that role, Mr. Albaugh was President and CEO of Boeing Integrated Defense Systems, and President of Rocketdyne Propulsion and Power. Mr. Albaugh is the Chairman of the National Aeronautic Association, past Chairman of the Aerospace Industries Association and serves on the Board of American Airlines and Harris Corporation.

• Janet C. Wolfenbarger, a retired four-star general who was responsible for procurement, science and technology, test and evaluation, logistics and supply chain for the U.S. Air Force; she oversaw an approximately $60 billion annual budget, including a large portion of the approximately $1 billion of business that Arconic does in the defense industry.

• Both of these new nominees know Arconic from having served as respected leaders at important Arconic customers. They bring operating experience and commercial insights that we believe will help optimize the Company and its strategy for many years. We are confident that these two nominees, like our other nominees, are independent and objective and seeking only to serve Arconic using their best judgment and insights from decades of relevant experience.

• They join our slate alongside three current Board members – our Interim CEO, the head of our Audit Committee and the head of our Cybersecurity Subcommittee. Together, these five nominees bring decades of experience in aerospace and defense.

2. This proxy fight isn’t a choice between “change” or “no change.” If Arconic’s candidates are elected, nine of 13 directors will have joined the Board in the last 16 months, making it one of the shortest tenured Boards in the S&P 500.

• Regardless of who wins this proxy fight, there will be change in the Board, and there will be new perspectives.

• Our slate of nominees has five new directors: two who have never served on our Board, two who have served for fewer than seven months and one who was originally nominated by Elliott and who joined the Board just last year.

3. The most important decision this Board will make in the coming months is the selection of a new CEO. Arconic’s recommended Board is without question best placed to select the next CEO, given its deep industry expertise and view of the marketplace.

4. We believe public companies should be run for all shareholders and should be governed ethically. Arconic’s Board refuses to allow one shareholder the right to shape a majority of the Board, select a CEO, or to unilaterally define how a board organizes itself and operates.

• Since Arconic’s CEO stepped down, Elliott has shifted its attacks to the Board level with increasingly personal attacks on directors and hyperbolic assertions that the Board is weak on governance. Elliott’s latest attack theme – “subversion of shareholder democracy” – is ironically being deployed in an effort to enable one 13.2% shareholder to shape a majority of the Board. If successful, Elliott will have nominated seven of Arconic’s 13 directors.

• A weak-governance Board would have ended this fight to spare themselves Elliott’s unfair attacks by agreeing, via settlement, to Elliott’s over-reaching demands - including its insistence on appointing a majority of both an Operating Committee and the CEO Search Committee.

• We also believe that hedge funds should not have free reign to level false or unsubstantiated accusations with the aim of embarrassing, ruining or damaging people.

• We believe that a vote on Elliott’s proxy card is a vote of encouragement for activists who demand undue influence as Elliott has clearly demanded at Arconic, and for activists to use tactics of personal destruction as their means.

• The Arconic Board urges shareholders not to cede undue and excessive influence over the Company and the CEO search process to Elliott, one shareholder with a 13.2% stake.

5. We delivered a strong first quarter as an independent Company, and are on track for the future. To keep the business healthy and build sustainable shareholder value, we need to ensure we continue to execute the right strategy, appoint a permanent CEO who will focus on value creation, and not compromise on sound governance. We need your support; vote the WHITE proxy card for the right kind of change to keep Arconic on a strong path.

• We are proud that Arconic is positioned well for the future. Last week, we announced strong earnings for the first quarter of 2017 – our first full quarter as a standalone company. Revenue was up 4.5% year over year, and strong performance and continued cost savings allowed Arconic to deliver net income that exceeded expectations. Our earnings announcement is a strong first data point that we are on the right path after the highly complex separation transaction that the Company executed this past November. Significant shareholder value has been created in just the first few months since the separation was completed.

• Arconic has a clear strategy to harness innovation, control costs and deepen our close customer relationships to generate value for shareholders. Our customers agree: Airbus, Boeing, United Technologies and GE Aviation have all expressed support for the strategy Arconic’s Board has endorsed.

• To keep the business healthy and build sustainable shareholder value, we need to ensure we continue to execute the right strategy, appoint a permanent CEO who will focus on value creation, and not compromise on sound governance. To do these things, we need your support and your vote.

• The Arconic Annual Meeting of Shareholders will take place on May 25, 2017 at 9:00 a.m. in Purchase, New York.

• Please vote for the principles and people that will create the best Arconic for shareholders. Vote on the White card for the Board’s recommended nominees. Details about the proxy voting. [LINK]

Colleagues,

Today, we announced the nomination of two exceptional new candidates to Arconic’s director slate for the 2017 Annual Meeting.

Former Boeing Commercial Airplanes President and CEO James “Jim” F. Albaugh and Air Force retired General Janet C. Wolfenbarger will stand for election alongside current directors David Hess, Amy Alving and Ulrich Schmidt.

Together, Arconic’s director nominees for the 2017 Annual Meeting have decades of combined aerospace and defense experience. Their deep expertise spans aerospace structures, jet engines, defense, manufacturing and engineering, technology, finance and purchasing – all highly relevant to Arconic’s core business.

If Arconic’s director nominees are elected, nine of 13 directors will have joined the Board in the last 16 months, making ours one of the shortest tenured Boards in the S&P 500.

We believe our slate represents the right kind of change at Arconic.

Read more in the Board’s Letter to Shareholders and the new investor presentation as well as our infographic. Below are the key points of today’s release.

The Arconic Annual Meeting of Shareholders will take place on May 25, 2017 at 9:00 a.m. in Purchase, New York.

Even if you previously voted on the WHITE proxy card, we ask that you vote “FOR” each of Arconic’s five nominees, including its two new nominees, by voting AGAIN on the new WHITE proxy card that will be issued.
