TempusAI reports $348.1M Q1 revenue

Tempus AI said on May 5 that first-quarter revenue rose 36.1% from a year earlier to $348.1 million, as its diagnostics and data businesses both posted double-digit growth. The Chicago-based company reported the results for the quarter ended March 31 in its quarterly filing and a same-day earnings release. Tempus said diagnostics revenue reached $261.1 million and data and applications revenue totaled $87.0 million. The company also raised its full-year 2026 revenue guidance to a range of $1.59 billion to $1.60 billion. ### Where did the $348.1 million come from? Diagnostics revenue of $261.1 million accounted for the largest share of Tempus AI’s quarterly sales, according to the company’s May 5 earnings release. Tempus said that segment grew 34.7% from a year earlier, driven by 28% oncology volume growth. Data and applications revenue of $87.0 million grew 40.5% year over year, the company said. Tempus said its Insights business, which includes data licensing and modeling, grew 44.1%. ### What did the company say about demand? Eric Lefkofsky, Tempus AI’s founder and chief executive, said in the earnings release that the quarter showed “accelerating demand” for the company’s AI-driven diagnostic platform and its multimodal data and AI models. The company tied the revenue increase to growth across its oncology and diagnostics services. MRD volume was about 6,500 tests in the first quarter, Tempus said, up about 500% from a year earlier. The company included that figure as one of the operating markers in its quarterly update. ### Did higher revenue translate into profit? Tempus AI reported a net loss of $125.9 million for the three months ended March 31, compared with a net loss of $68.0 million a year earlier, according to its Form 10-Q. The filing said the company generated total revenue of $348.1 million in the quarter, up from $255.7 million in the same period of 2025. The March 31 balance sheet showed $643.8 million in cash and marketable securities, according to the earnings release. The Form 10-Q separately listed $525.9 million in cash, cash equivalents and restricted cash, plus marketable equity securities. ### What stood out in the filing beyond the headline number? Related-party revenue totaled $21.8 million in the first quarter of 2026, up from $631,000 a year earlier, according to the Form 10-Q. The filing included that figure in the notes to the condensed consolidated financial statements. Operating expenses and costs continued to run above revenue. The Form 10-Q showed total costs and operating expenses of $432.8 million for the quarter, producing a loss from operations of $84.7 million. ### What did Tempus change about its outlook? Tempus AI said it increased full-year 2026 revenue guidance to $1.59 billion to $1.60 billion. The company also said it expects full-year 2026 adjusted EBITDA of about $65 million. March 31 remains the quarter-end date for the reported period, and the next scheduled checkpoint for investors will be Tempus AI’s second-quarter results and filing later in 2026. Tempus shares trade on Nasdaq under the ticker TEM, and the company’s May 5 Form 10-Q is available through its investor relations site and the U.S. Securities and Exchange Commission.
