CTM Castellum Inc

Castellum, Inc. (the "Company" or "Castellum") (NYSE-American: CTM), a cybersecurity, electronic warfare, and software services company focused on the federal government, releases this letter to shareholders from Chief Executive Officer ("CEO"), Glen Ives.

Dear Fellow Shareholders:

This letter represents my first formal communication with you since I was appointed CEO by the Board of our Company earlier this month. I am greatly honored by the appointment and feel very humble to take on the responsibility of serving our employees and you, our shareholders. Let me start by introducing myself and then sharing a few thoughts about where I would like to lead us over the coming months and years.

I grew up as an Army brat before attending and graduating from the U.S. Naval Academy at Annapolis. I served 34 years in the Navy, where I met my wife (also a Naval Academy graduate and a member of the first class of women to enter the Academy and a far more accomplished graduate than me). Initially, I was a pilot, flying Navy helicopters from destroyers and carriers, and I flew many different aircraft later as a test pilot. I served on several senior joint staffs and in major acquisition roles. During my final Navy tour, I served as Commanding Officer of the world's finest Naval Air Station Patuxent River, where I developed many long-term friendships and became intimately involved in the local community. Patuxent River is a key Research, Development, Test, and Evaluation military base where approximately $45 billion of contracts are executed yearly. In 2008, I retired from the Navy and transitioned to industry with a government contractor, Sabre Systems. I helped build that company as President, bringing together a strong team and overseeing a more than doubling of its revenue during my tenure and transforming the company into a leading-edge technology solutions and services company with numerous prime contracts and new capabilities in Full Spectrum Offensive and Defensive Cyber, AI/ML, Enterprise Data Management, Advanced Communications Technologies and Digital Transformation. In 2021, I joined Castellum to help build its Navy Division. I then became Chief Operating Officer prior to my recent appointment as CEO.

In my view, Castellum has tremendous potential as a company. As I write this, we have 254 tremendous employees. Through their unparalleled dedication, world-class professionalism, knowledge, experience, and talents, we can provide critically important services and technology solutions to our mission customers, who are directly responsible for many vital aspects of our nation's security and well-being. We could not be more honored and prouder of our role and mission. We have numerous contracts, including some very important prime contracts. We have strong and relevant capabilities, past performance, and solid relationships based on trust and mutual respect with our government customers. We have good teaming partners and a top-notch protégé company. Castellum and our four subsidiary companies, Corvus Consulting, LLC, Mainnerve Federal Services, Inc., Specialty Systems, Inc., and Global Technology and Management Resources, Inc., is a well-grounded platform and rock-solid business poised for real growth.

Over the next two years, I would like to see Castellum grow organically faster than we have previously. We have a good pipeline of opportunities that we are building even stronger, and we need to convert that pipeline into revenue and profit growth. At a minimum, I would like to see us grow organically 25% over the next two years and 40% over the next three years. This would take us above $56 million in annualized revenue by mid-2026 and $63 million in annualized revenue by mid-2027. I would like to see us get to $5 million a year in adjusted earnings before interest depreciation and amortization ("EBITDA") and U.S. GAAP net income positive during that time. While we are not currently under a letter of intent with any acquisitions, I would like to return to making selective acquisitions as our balance sheet strengthens. I believe we are one good acquisition away from really accelerating our growth.

Financially, we need to continue to pay down debt and build financial muscle. We recently announced that we have retired our Live Oak Banking Company term loan. We plan to retire the $2.4 million Buckhout Charitable Remainder Trust note over the next two years (by August 2026) and reduce our other debt as well. As you know, retiring debt strengthens our balance sheet, gives us financial flexibility to potentially make acquisitions, reduces financial risk to our Company, and, someday, will allow us to return capital to our shareholders. Ideally, we are looking to get our debt below 15% of revenue and 2.5x adjusted EBITDA. We could be there in less than a year with just some growth and steady debt retirement.

If we can achieve these goals, we, the shareholders, will benefit. I am acutely aware that our stock price has not done well over the past 20 months. However, if we execute our plan, I am confident that the next 20 months will be quite different from the past 20 months to all of our benefit.

In closing, I'd like to say again I could not be more honored, encouraged, and committed as your CEO. I'm grateful to have our world-class team here at Castellum and our exceptional government customers with vital missions we share. I know and appreciate that we will all work, serve, and pull together with trust, respect, honesty, and faith in one another and our mission to achieve our success. I know we can, and I know we will because, quite simply, that is our character, individually and as a team. I believe that there is nothing we cannot do and achieve together as we commit and work to build and institutionalize a true winning culture here at Castellum for all of us.

I sincerely welcome and encourage your thoughts, ideas, and help as we build our Company over the coming quarters, and I look forward to serving you and leading Castellum to many good things ahead.

Sincerely,

Glen Ives, CEO
