TSS Reports Third Quarter 2025 Financial Results

Year-to-date revenue of $184.8 million, up 88%

2025 Outlook Updated to Reflect Growth Investments

GEORGETOWN, TEXAS – Nov. 13, 2025 – TSS, Inc. (Nasdaq: TSSI), a data center services company that integrates AI and other high-performance computing infrastructure and software and provides related data center services, today reported results for its third quarter ended September 30, 2025.

“Our year-to-date revenue growth of 88% and Adjusted EBITDA improvement of 59% underscore the strength and momentum of our business.  This quarter’s procurement revenues reflect a comparison against last year’s exceptionally strong Q3 results.  In our Systems Integration business, where we deliver infrastructure to serve the exploding AI market, the volume of racks we integrated was lower than expected due to unforeseen operational requirements.  We have implemented new procedures and processes and are seeing dramatically higher rack volumes in our fourth quarter.  Costs reflect a full quarter of our new factory that in the third quarter were not matched by the additional revenues we expect to increase beginning in the fourth quarter plus additional investment in the facility itself”, said Darryll Dewan, CEO of TSS, Inc.

Fourth Quarter Outlook

Dewan added, “Two years of rapid growth, a focus on operational excellence and strong relationships with key partners have driven our performance year-to-date. We expect elevated performances from Procurement although the government shutdown may impact pipeline orders closing in the calendar year. Systems Integration and Facilities Management should both have stronger results in the fourth quarter, resulting in a strong rebound in quarterly EBITDA. Accordingly, we are updating our full year 2025 Adjusted EBITDA outlook to a range between 50% and 75% growth compared to 2024.  This run rate should carry into 2026 and result in another year of rapid revenue and EBITDA growth.”

About Non-GAAP Financial Measures

Adjusted EBITDA is a supplemental financial measure not defined under Generally Accepted Accounting Principles (GAAP). We define Adjusted EBITDA as net income (loss) before net interest expense, income taxes, depreciation and amortization, impairment loss on goodwill and other intangibles, stock-based compensation, and certain extraordinary items. We present Adjusted EBITDA because we believe this supplemental measure of operating performance is helpful in comparing our operating results across reporting periods on a consistent basis by excluding items that may or could have a disproportionately positive or negative impact on our results of operations in any particular period. We also use Adjusted EBITDA as a factor in evaluating the performance of certain management personnel when determining incentive compensation.

Adjusted EBITDA may not be comparable to similarly titled measures reported by other companies. Adjusted EBITDA, while providing useful information, should not be considered in isolation or as an alternative to net income or cash flows as determined under GAAP. Consistent with Regulation G under the U.S. federal securities laws, Adjusted EBITDA has been reconciled to the nearest GAAP measure; this reconciliation is located under the heading “Adjusted EBITDA Reconciliation” following the Consolidated Statements of Operations included in this press release.
