TSS Reports First Quarter 2026 Financial Results

Total Revenue of $55.3 Million

Systems Integration Revenue Increased 88% Year-Over-Year

 Refines Full-Year 2026 Outlook; Now Expects Adjusted EBITDA Toward High End of $20 to $22 Million Range

GEORGETOWN, TEXAS – May 7, 2026 – 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 first quarter ended March 31, 2026.

“We delivered strong growth in our higher margin Systems Integration business in the first quarter, with revenue increasing 88% year over year, driven by strong customer demand and solid operational execution with growth particularly high in our AI activities,” said Darryll Dewan, CEO of TSS, Inc. “Total revenue comparisons were affected by record high volumes in the first quarter of last year in our lower-margin Procurement business, which can vary from quarter to quarter. Importantly, our first quarter results were in line with our expectations, underscore the strength of our core business and reinforce our confidence in achieving our outlook for the full year.

“Our Georgetown, Texas AI rack integration facility has been running at increasing scale for six months. As a result, our quarterly EBITDA levels have grown and will continue to grow along with AI rack volumes. We are working to expand the markets we serve in terms of both customers and service offering. We have strengthened our leadership team with the addition of a chief strategy officer and a chief technology officer, whose deep industry expertise, proven leadership and extensive global networks position us to accelerate both organic expansion and strategic growth initiatives within our current customer base as well as opportunities to expand beyond our current customers.”

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 and bank factoring costs, 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. The Company is unable to provide a reconciliation of forward-looking Adjusted EBITDA to GAAP net income because certain reconciling items are outside the Company’s control or cannot be reasonably predicted without unreasonable efforts. These items may include stock-based compensation expense, fluctuations in prevailing interest rates and the resulting impacts on bank factoring fees, interest expense and interest income, and other adjustments that may be material.
