Castellum, Inc. (NYSE-American: CTM): Fortifying Cybersecurity and Mission-Critical Services for Federal Clients

Published on March 17, 2025 | Ticker: CTM

Business Overview and Historical Highlights

Castellum, Inc. (NYSE-American: CTM) is a leading provider of cybersecurity, electronic warfare, and software engineering services catering to the critical needs of the U.S. federal government. With a steadfast commitment to national security and a proven track record of delivering mission-essential solutions, Castellum has emerged as a trusted partner for government agencies navigating the evolving technological landscape.

Castellum's history dates back to 2010 when it was incorporated in Nevada under the name Passionate Pet, Inc. The company underwent several name changes, becoming Firstin Wireless Technology, Inc. in 2013 and BioNovelus, Inc. in 2015. However, the true transformation of Castellum began in 2019 with the acquisition of Bayberry Acquisition Corporation and Corvus Consulting, LLC. This pivotal moment marked the company's shift towards becoming a technology-focused entity specializing in cybersecurity, IT, electronic warfare, information warfare, and information operations.

The Bayberry acquisition brought in key leadership, including Jay Wright and Mark Fuller, who became officers and directors of the newly formed Castellum. This strategic move set the stage for the company's future growth and expansion in the government services sector.

Following the transformative acquisitions in 2019, Castellum continued its growth strategy through a series of strategic acquisitions. In 2021, the company acquired Mainnerve Federal Services, Inc., Merrison Technologies, LLC, and Specialty Systems, Inc., further expanding its capabilities and market presence. The acquisition of Global Technology and Management Resources, Inc. in 2023 further solidified Castellum's position in the federal market.

These acquisitions have allowed Castellum to significantly enhance its service offerings, increase market share, gain access to new contracts, and achieve cost efficiencies. The company's growth strategy has been focused on integrating complementary businesses to create a comprehensive suite of services for federal clients.

Despite its impressive growth trajectory, Castellum has faced some challenges along the way. In 2023, the company recorded a $6.92 million non-cash goodwill impairment charge related to a decline in its stock price. Additionally, operating in the government contracting space has required Castellum to navigate a complex regulatory environment, adhering to various laws and regulations related to the formation, administration, and performance of government contracts.

Financials and Key Metrics

Castellum has demonstrated steady financial performance, although the company has faced some challenges in recent years. In the fiscal year 2024, the company reported revenue of $44.8 million, a slight decrease from the previous year's $45.2 million. This decrease was primarily attributed to the sale of the Mainnerve Federal Services, Inc. (MFSI) subsidiary in September 2024. However, the company's operating loss improved significantly, narrowing from $16.7 million in 2023 to $7.2 million in 2024, thanks to strategic cost-saving initiatives and enhanced operational efficiencies.

One of the key financial metrics Castellum focuses on is Adjusted EBITDA, a non-GAAP measure that provides insight into the company's core operating performance. In 2024, Castellum reported Adjusted EBITDA of $0.8 million, a positive result that excludes non-cash charges, such as stock-based compensation and impairment of goodwill.

Castellum's net income for 2024 was -$10 million, reflecting the ongoing challenges and investments in growth initiatives. The company's operating cash flow remained positive at $1.12 million, which was also its free cash flow for the year.

In terms of quarterly performance, Castellum showed sequential revenue growth in 2024, with Q3 revenue reaching $11.6 million, up from $11.5 million in Q2 and $11.3 million in Q1.

Liquidity and Capital Structure

Castellum's balance sheet remains well-capitalized, with $12.0 million in cash and cash equivalents as of December 31, 2024. The company has been actively managing its debt load, reducing its total debt from $11.9 million in 2023 to $10.3 million by the end of 2024. This deleveraging strategy has enhanced Castellum's financial flexibility and positioned the company for future growth.

The company's liquidity position is further strengthened by its solid current ratio of 1.92 and quick ratio of 1.92 as of December 31, 2024. These ratios indicate that Castellum has sufficient short-term assets to cover its short-term liabilities.

Castellum's debt-to-equity ratio stood at 0.57 as of December 31, 2024, reflecting a relatively balanced capital structure. The company had access to a $4 million revolving credit facility with Live Oak Bank as of February 2024, which was later reduced to $2 million in August 2024, providing additional financial flexibility if needed.

Operational Highlights and Strategic Initiatives

Castellum's operational success is driven by its unwavering focus on delivering mission-critical services to federal clients. The company's capabilities span a wide range of areas, including intelligence analysis, software development, program management, cybersecurity, and data analytics.

One of Castellum's key strategic initiatives is its acquisition and integration strategy. The company has demonstrated a proven ability to identify and successfully integrate complementary businesses, leveraging synergies to enhance its service offerings and expand its customer base. For example, the GTMR acquisition has strengthened Castellum's presence in the classified government services market, while the SSI acquisition has bolstered the company's software engineering and IT capabilities.

Additionally, Castellum has placed a strong emphasis on organic growth, investing in talent development and technology innovation to stay ahead of the curve in the rapidly evolving government services industry. The company's recent hiring of Tanya Bassett as Vice President of Business Development and Capture Management underscores its commitment to driving sustainable growth through strategic business development initiatives.

Revenue Streams and Contract Types

Castellum generates its revenue primarily from services provided to U.S. federal, state, and local government agencies. The company operates in a single reporting segment focused on providing expertise and technology in the areas of information technology (IT), electronic warfare, information warfare, and cybersecurity to government and commercial customers.

Castellum's revenues are derived from three main contract types: 1. Time-and-Materials (T&M) contracts: Accounted for 54.7% of total revenues in 2024 2. Cost Plus Fixed Fee (CPFF) contracts: Represented 39.0% of total revenues in 2024 3. Firm-Fixed-Price (FFP) contracts: Contributed 6.3% of total revenues in 2024

The company uses different revenue recognition methods for each contract type based on the nature of the work performed.

Customer Concentration and Backlog

Castellum has a concentrated customer base, with its top three revenue-producing contracts accounting for 49% of total 2024 revenues, or $21.97 million. These contracts are with the U.S. Navy's Naval Air Systems Command (NAVAIR), Peraton, Inc., and the Naval Sea Systems Command (NAVSEA).

As of December 31, 2024, Castellum had a total backlog of $100.48 million, consisting of:

$12.74 million in funded backlog
$15.37 million in unfunded backlog
$72.37 million in priced options

The company expects to recognize approximately 28% of the remaining performance obligations over the next 12 months and 49% over the next 24 months, providing visibility into future revenue streams.

Competitive Landscape and Risks

Castellum operates in a highly competitive market, vying for contracts with large government services providers such as Northrop Grumman, CACI International, and Booz Allen Hamilton. The company's ability to differentiate itself through its specialized expertise, innovative solutions, and strong customer relationships has been crucial to its success.

However, Castellum faces several risks that could impact its future performance. The volatile nature of government budgets and the potential for spending cuts or program delays pose a significant challenge. Additionally, the company's reliance on security clearances and the ability to retain and attract skilled personnel are critical factors that could affect its operations.

The company's business is heavily concentrated in the U.S. government market, particularly with Department of Defense agencies, which accounted for substantially all of its 2024 revenues. This concentration exposes Castellum to risks associated with changes in government spending priorities and policies.

Outlook and Conclusion

Despite the challenges, Castellum remains well-positioned to capitalize on the growing demand for mission-critical services in the federal government. The company's focus on cybersecurity, electronic warfare, and software engineering aligns with the government's heightened emphasis on national security and technology modernization.

Castellum's strategic acquisitions, organic growth initiatives, and strong customer relationships have positioned the company as a trusted partner for government agencies. As the company continues to navigate the evolving landscape, its ability to deliver innovative solutions and maintain its operational excellence will be crucial to its long-term success.

The company's growth strategy, focused on expanding its service offerings and customer base through strategic acquisitions while maintaining a strong backlog of contracted work, provides a solid foundation for future growth. With a well-capitalized balance sheet, improving operational efficiency, and a robust pipeline of opportunities, Castellum is poised to strengthen its position in the government services market and drive long-term value for its stakeholders.
