Aerojet Rocketdyne Executive Chairman Warren Lichtenstein Sends Letter to Fellow Shareholders Regarding Critical Vote at June 30^th Special Meeting

Urges Shareholders to Vote on the GREEN Proxy Card to Elect His Refreshed Slate of Eight Highly Qualified Director Candidates, Which Possesses the Right CEO and a Superior Strategy

NEW YORK--(BUSINESS WIRE)--Aerojet Rocketdyne Holdings, Inc. (NYSE: AJRD) (“Aerojet Rocketdyne” or the “Company”) Executive Chairman Warren Lichtenstein, who collectively with his affiliates and the participants in his solicitation owns approximately 5.6% of the Company's outstanding shares, today sent the below letter to shareholders in connection with a special meeting of shareholders (the “Special Meeting”) scheduled to be held on June 30, 2022. Mr. Lichtenstein is seeking support on the GREEN Proxy Card to elect his recently refreshed slate of highly qualified candidates to the Company’s Board of Directors (the “Board”). Learn more about the slate and its plan for enhanced value creation by visiting www.SaveAerojet.com.

Dear Fellow Shareholder,

Thank you for your investment in Aerojet Rocketdyne and your willingness to evaluate the refreshed slate of director candidates I have nominated for election at the June 30^th Special Meeting.

I want you to know it remains my privilege to be aligned with you and champion your interests in the boardroom. Since making an initial investment in 2000 and joining the Board in 2008, I have focused on helping the Company transform into a technology-led aerospace and defense business that can grow with its customers and produce long-term value for its shareholders. I am proud that this focus has helped drive an approximately 7x increase in the Company’s market capitalization and more than 250% total shareholder returns. With that said, Aerojet Rocketdyne has to continue building on – not giving back or resting on – past results.

I also want to acknowledge at this time that it has been a very difficult and tumultuous period for the Company. When Lockheed Martin terminated its acquisition in February following more than a year of very public headwinds, we were not prepared with the comprehensive contingency plan sought by myself and a subset of the Board – resulting in disruptions for employees, customers and shareholders. When it came time for the current Board to nominate a slate for the 2022 Annual Meeting, we were unable to reach consensus – resulting in more disruptions. Additionally, my differences of opinion with Chief Executive Officer Eileen Drake led her to initiate a distracting internal investigation (that rejected claims of harassment and retaliation) and then compelled me to file litigation over her misuse of shareholders’ resources to pursue boardroom control. Although I always seek to do what is in your best interest, I know the status quo is unacceptable and that all of the Company’s stakeholders deserve better.

In the lead-up to the Special Meeting, it has very much been a tale of two stories. Ms. Drake and her allies contend everything has been fine at Aerojet Rocketdyne except for me. They have consistently deflected attention away from the operational and financial deterioration that has set in over the last 18 months by attacking me – an engaged Executive Chairman who has put his money where his mouth is with a more than $150 million stake and an irrefutable record of long-term value creation. They have maintained this posture even while Ms. Drake, who has never purchased a share of Aerojet Rocketdyne on the open market, has reportedly sought $48 million of shareholders’ money to leave. But rather than continue engaging in a tit-for-tat, I want to focus your attention on what actually matters today: since December 2020, a lack of contingency planning and poor operational oversight at Aerojet Rocketdyne has led to a nearly 80% decline in real free cash flow, numerous customer complaints, sustained employee attrition and several defense and space programs going from the black into the red. I would have fought harder from the boardroom to fix these issues had I not been effectively sidelined for most of the past 18 months by Ms. Drake’s investigation and her management team’s documented efforts to block my access. The fact that Ms. Drake’s faction will not assume any accountability for these issues speaks volumes about its lack of credibility and unfitness to lead.

By voting on the GREEN Proxy Card to elect my refreshed slate of director candidates at the upcoming Special Meeting, I am confident you can help usher in the better future we all want. Here is an overview of what my eight-member slate is offering: 

1. The Right Level of Credibility – Our slate, which includes six new director candidates and only two incumbents, possesses necessary experience in capital allocation, corporate governance, government relations, mergers and acquisitions, and various operational areas. Several members of the slate also have meaningful shareholdings and direct experience as Aerojet Rocketdyne customers. Lastly, our slate has already committed to immediate governance enhancements such as appointing a lead independent director, phasing out the Executive Chairman role, expanding the Board to nine directors, and reestablishing quarterly earnings calls and more substantive shareholder engagement throughout the off-season. Instead of believing Ms. Drake’s baseless claim that this refreshed slate is comprised of “friends,” I ask that you assess each nominee’s background and engage with us. You will find that each candidate is fiercely independent and has value-add expertise aligned with the Company’s needs.

2. The Right Chief Executive Officer – Our slate has recruited Mark Tucker, Aerojet Rocketdyne’s former Chief Operating Officer from 2015 through 2020, to return to the Company as Chief Executive Officer. He has more than three decades of defense and space sector experience, including holding various senior operating roles at Northrop Grumman Corporation. His industry expertise and institutional knowledge of Aerojet Rocketdyne make him the ideal leader to reverse the financial and operational deterioration that has set in since the Lockheed Martin transaction was announced in late 2020. As documented in the recent shareholder presentation that can be found at www.SaveAerojet.com/resources, the Company needs to immediately fix its diminishing cash flows, frayed customer relationships and unhappy employee base. Mr. Tucker has the acumen and vision to address these challenges. He is also squarely aligned with investors, with several million dollars of shareholdings and a stated intent to purchase more shares on the open market after the Special Meeting.

3. The Right Plan and Strategy – As many of you heard from Mr. Tucker on his recent shareholder call, our slate’s plan entails healing the organization so that employees, customers and shareholders once again trust us. From there, he believes the Company can produce at least $65 per share in value over the next three years and unlock growth opportunities for the longer term by (i.) establishing fundamentally sound program operations, (ii.) initiating smarter capital allocation and (iii.) investing in R&D tied to the future of propulsion technologies. If strategic alternatives present themselves, our slate is equally committed to evaluating those opportunities with an open mind and through a comprehensive, transparent process. Unlike Ms. Drake, who is not acknowledging the Company’s vulnerabilities or providing a comprehensive plan, Mr. Tucker and our slate have detailed their multi-faceted strategy in the shareholder presentation found at www.SaveAerojet.com/resources.

Looking ahead, I urge all shareholders of Aerojet Rocketdyne to evaluate their voting decision based on these three prongs. The path to a more stable future and long-term value creation begins with a credible Board, a high-quality Chief Executive Officer and a viable strategy. That is exactly what my slate is offering. There is no need to roll the dice on Ms. Drake, who seems to be focused on a fire sale in this challenging market environment, when the Company has so much potential that can be realized in the coming quarters and years under Mr. Tucker and the right leadership.

Thank you for your consideration. My fellow nominees and I look forward to earning your support on the GREEN Proxy Card.

Sincerely,

Warren G. Lichtenstein

Executive Chairman

Aerojet Rocketdyne Holdings, Inc.
