One Stop Systems CEO and Chairman Issue Letter to Shareholders

ESCONDIDO, Calif., April 17, 2025 (GLOBE NEWSWIRE) -- One Stop Systems, Inc. (“We”, “OSS” or the "Company") (Nasdaq: OSS), a leader in rugged Enterprise Class compute for artificial intelligence (AI), machine learning (ML) and sensor processing at the edge, today issued a shareholder letter, which reviews the progress it made in 2024 and the Company’s expectations for 2025.

Dear Fellow Shareholders

We are excited to share the progress we made in 2024 and the opportunities ahead to profitably grow our business and create significant value for our shareholders. 2024 was a transformative year for OSS. We successfully executed a strategic transition that not only reshaped our business, but we also believe positioned us at the forefront of one of the most dynamic and rapidly growing markets—high-performance edge compute (HPeC) for AI, machine learning (ML), autonomy, and sensor fusion at the edge.

Our ability to adapt and innovate fueled sequential revenue growth for every quarter of 2024, expanded our order volumes, and strengthened our sales pipeline. As demand for intelligent, real-time processing continues to grow across industries—from defense to aerospace to industrial and commercial applications—OSS is well positioned to capitalize on these powerful market trends.

Since joining in June 2023, I have talked about a multi-year strategy aimed at producing significant growth within our OSS segment. Our efforts have been focused on three phases. During 2023 we successfully executed our first phase and strengthened our foundation by adding new management and board talent, and pivoting our strategy to pursue higher-margin, higher-growth opportunities across defense and commercial markets. These efforts developed a comprehensive go-to-market strategy, rebuilt our sales pipeline to over $1 billion, and reduced our exposure to legacy low margin, non-core markets.

With a proper foundation in place to support a larger business, throughout 2024 we executed against our second phase of transformation aimed at converting our pipeline to orders and increasing our competitive position more broadly across defense markets.

Looking at the progress of our second phase, during 2024 we created a new customer funded development revenue stream to provide more integrated solutions to our customers and establish OSS as a platform incumbent on large, multi-year programs. We believe these efforts will provide meaningful benefits to our business over the long term by contributing a higher mix of predictable recurring revenue and multi-year backlogs.  

Customer funded development revenue grew by 118% in 2024 to $3.7 million. While still small numbers, this growth highlights our initial efforts to pursue programs that establish OSS in an incumbent position on key military and commercial applications. Development relationships are expected to take one to two years before leading to production orders. As a result, we expect certain development programs that we worked on during 2024 to transition to orders and sales in 2025. This includes commercial applications in datacenter, healthcare, and aerospace markets, combined with multiple opportunities across the U.S. Department of Defense.

Throughout 2024, we also experienced greater adoption within our OSS segment from both defense and commercial end markets. We continue to experience high levels of interest in our solutions and increasing requests for information, proposals and white papers, as customers look for technology partners like OSS to support their expanding and highly specialized needs. These trends helped grow our customer base and broaden our customer concentration during the year.

OSS segment growth in our defense market was from new and existing programs. We experienced demand from several programs within the U.S. Army, a renewal for the U.S. Navy P-8 program, a new HPeC solution for a U.S. intelligence agency and a new design win with a leading defense contractor in Asia for an autonomous maritime application.

Within the defense market, we continue to work on a rugged 360-degree Situational Awareness system for the U.S. Army. If the Army chooses to fund and field this system across one or multiple combat vehicles, we estimate the value of such an opportunity could exceed $200 million in production orders over a three-to-five-year period with additional opportunities for follow on logistics, support and tech refresh options

In our commercial end market, we experienced customer demand for our solutions from several sectors, including motorsport, autonomous trucking, commercial aerospace, and, importantly, the datacenter markets. We are pursuing a potential $200 million multi-year pipeline opportunity to provide our solutions within the composable infrastructure/datacenter market. In 2024, we announced an initial contract for 100 units with a datacenter customer. We expect our best-in-class solution will expand to multiple customers in 2025, leading to increased revenue potential for 2025 and beyond.

While the U.S. Army Situational Awareness or composable infrastructure/datacenter opportunities remain subject to fielding and funding decisions, they represent transformative opportunities that we are pursuing to significantly transform our OSS segment

Finally, after a weaker economy in Europe in 2024, our Bressner segment is off to a good start in 2025 with anticipated rising demand throughout the year. Our embedded position remains strong with our customers, and the programs we have pursued are aligned with our customers’ priorities. As a result, we currently expect the 2025 annual book-to-bill ratio for our OSS segment to be on the order of 1.2x. We believe a higher expected book-to-bill for 2025, on a base of higher annual revenue, showcases accelerating momentum underway for our HPeC and enterprise class compute solutions.

We anticipate consolidated revenue of $59 to $61 million for the full year of 2025. This includes expected OSS segment revenue of approximately $30 million, representing over 20% year-over-year growth in the OSS segment. In addition, the Company expects to be EBITDA break-even for the full year of 2025. It is important to note that we expect revenue and profitability to improve at a higher rate in the second half of 2025 based on current trends and our expanding sales pipeline.

Our solutions remain in demand and our opportunities across our commercial and defense markets are only increasing, despite recent economic and trade policies that have increased the level of global economic uncertainty over the near term. We are monitoring the potential impact tariffs may have on our supply chain. In addition, we are beginning to see opportunities emerge as certain of our product lines, specifically in our commercial markets, have the potential to be more competitive against foreign competition.

As we enter the third year of our transformation, we are proud of our team and what we have accomplished so far and are excited to enter this next phase of accelerating growth and improving profitability.

We believe the investments we made in 2023 and 2024 have established a solid foundation for scaling our business and capturing transformative revenue opportunities. We believe we have the right products, the right team, and the right strategy to meet the increasing demand for rugged, enterprise-class computing solutions across defense and commercial markets.

On behalf of the OSS team and Board of Directors, we extend my sincere appreciation to our employees for their dedication, our customers for their trust, and our shareholders for their continued support. Our commitment remains steadfast: to deliver innovative solutions, drive sustainable growth, and enhance shareholder value.

Respectfully,

Mike Knowles
