QT Imaging Holdings, Inc. (Nasdaq: QTI) (“QT Imaging” or the “Company”) a medical device company dedicated to transforming breast health management through innovative, radiation-free imaging technology, today announces preliminary unaudited financial results for the fourth quarter and full year ended December 31, 2025.

“Q4 marked a pivotal moment for the Company with record quarterly revenue driven by a record number of scanners shipped, and strong execution across our commercial and product initiatives,” said Dr. Raluca Dinu, Chief Executive Officer. “Exceeding our 2025 revenue outlook and successfully relisting on Nasdaq in under a year underscore the strength of our team, the resilience of our strategy and growing patient awareness and demand for our breast imaging alternative. As we continue our transition from a traditional scanner company to a SaaS and biomarker-driven medical imaging platform, we believe we are building a scalable, data centric business positioned for long-term growth.”

Fourth Quarter and Recent Business Highlights

• The Company shipped 17 QTI Breast Acoustic CT™ scanners and generated record revenue of $8.3 million in the fourth quarter of 2025, up 97% and 877% from the third quarter of 2025 and fourth quarter of 2024, respectively. For 2025, the Company shipped 40 scanners and generated record revenue of $18.9 million, surpassing its revenue guidance of $18.0 million.
• Significantly strengthened its financial position through a private placement with gross proceeds of $18.2 million, which included lead investor Sio Capital and participation from other institutional and existing Company investors.
• Uplisted from the OTCQB Venture Market to the Nasdaq Capital Market after having met all listing requirements, including financial, corporate governance and regulatory criteria.
• Entered into a strategic collaboration with Intelerad Medical Systems, a global leader in providing medical imaging solutions, which supports QT Imaging’s mission to deliver safe, quantitative and accessible imaging by enabling seamless integration of QT Imaging’s Breast Acoustic CT™ Scanners with Intelerad’s secure, cloud-based platform to deliver QT Imaging’s Cloud SaaS Platform to its customers.
• Announced a collaboration with Olea Medical, a renowned provider of advanced medical imaging software, enhancing the QTI Cloud SaaS Platform by integrating Olea Medical’s advanced visualization, quantitative analytics and AI-ready imaging technologies to support clinical interpretation, research workflows and quantitative imaging analysis.

The agreement provides for committed, minimum order quantities of seven scanners in 2026 (starting in the second quarter), increasing to 16 scanners in 2027 and 20 scanners in 2028, for a total minimum of 43 scanners representing revenue of more than $24 million.

Summary of Preliminary Unaudited Fourth Quarter 2025 Financial Results

• Revenue was $8.3 million for the fourth quarter of 2025, representing 877% year-over-year growth and 97% sequential-quarter growth, respectively. The increase was primarily attributable to the shipment of 17 QT Breast Acoustic CT™ scanners in the period to the Company’s U.S. distributor NXC Imaging.
• Gross margin of 38% in the fourth quarter of 2025 compared to 47% in the fourth quarter of 2024. The decline was primarily attributable to the shipment of two scanners that were built by our contract manufacturing partner at a higher cost due to tariffs and other fees.
• Total operating expenses for the fourth quarter of 2025 were $3.8 million, a 57% increase from $2.5 million in the same period of 2024. This was primarily attributable to increases in employee compensation costs and professional and outside service costs, partially offset by an increase in the allocation of overhead expenses from operating expenses to cost of revenue.
• Net loss of $1.4 million for the fourth quarter of 2025 improved 60% compared to a net loss of $3.5 million for the fourth quarter of 2024.
• Non-GAAP Adjusted EBITDA* of $(0.4) million for the fourth quarter of 2025 improved 79% compared to $(1.9) million for the fourth quarter of 2024.
• Net cash used in operating activities during the fourth quarter of 2025 was $3.1 million compared to $1.2 million in the fourth quarter of 2024. The increase was primarily due to an increase in accounts receivable to $5.8 million as of December 31, 2025, which was subsequently collected, partially offset by a lower net loss as adjusted for non-cash operating activities.
• As of December 31, 2025, the Company had cash, restricted cash, and cash equivalents of $10.5 million.

Summary of Preliminary Unaudited Full Year 2025 Financial Results

• Revenue was $18.9 million for 2025, surpassing the Company’s guidance of $18 million and representing 288% growth compared to 2024.
• Gross margin was 45% for 2025, compared to 54% for 2024. The decline was primarily attributable to two scanners that were built by our contract manufacturing partner at a higher cost, including tariffs and other fees.
• Total operating expenses for 2025 were $13.0 million, a 12% improvement from $14.8 million in 2024. This was primarily attributable to a $3.6 million decrease in professional fees associated with transaction costs, a $1.7 million increase in the allocation of overhead expenses from operating expenses to cost of revenue, and a $0.3 million reduction in insurance expense, partially offset by a $2.8 million increase in compensation and benefits and a $0.4 million increase in professional and outside services.
• Net loss was $21.1 million for 2025, which included other expense of $8.8 million consisting of non-cash expense of $6.6 million incurred at the issuance of the Lynrock Lake Term Loan, an extinguishment loss of $2.1 million for the Yorkville Note and Cable Car Note, and a $0.1 million extension fee for the Cable Car Note, as well as a $3.6 million increase in the fair value of warrant liability and a $1.8 million increase in the fair value of earnout liability. This compared to a net loss of $9.0 million for 2024.
• Non-GAAP Adjusted EBITDA* of $(3.5) million for 2025, improved 52% compared to $(7.4) million for 2024.
• Net cash used in operating activities for 2025 was $9.0 million compared to $10.0 million in 2024.

Preliminary Financial and Operating Results

The financial information in this press release is preliminary, unaudited, based on currently available information and subject to adjustment in the final financial statements to be filed with the Company's Annual Report on Form 10-K for the year ended December 31, 2025. The preliminary results set forth above reflect preliminary, unaudited estimates based solely on currently available information, which is subject to change. Such preliminary results are subject to the finalization of year-end financial and accounting procedures. While carrying out such procedures, QT Imaging may identify items that would require it to make adjustments to the preliminary estimates of financial results set forth herein. As a result, QT Imaging’s actual financial results could differ from the information set forth herein and such differences could be material. Moreover, preliminary and estimated financial results should not be viewed as a substitute for QT Imaging’s full annual financial statements for the year ended December 31, 2025, which will be prepared in accordance with accounting principles generally accepted in the United States (“GAAP”).

Non-GAAP Financial Measures

The financial information and data contained in this press release is unaudited. Some of the financial information and data contained in this press release, such as EBITDA and Adjusted EBITDA, have not been prepared in accordance with GAAP. To supplement our unaudited condensed consolidated financial statements, which are prepared and presented in accordance with GAAP in our press release, we also report certain non-GAAP financial measures. A “non-GAAP financial measure” refers to a numerical measure of a company’s historical or future financial performance, financial position or cash flows that excludes (or includes) amounts that are included in (or excluded from) the most directly comparable measure calculated and presented in accordance with GAAP in such company’s financial statements. Non-GAAP financial measures should not be considered in isolation or as a substitute for the relevant GAAP measures and should be read in conjunction with information presented on a GAAP basis. Because not all companies use identical calculations, our presentation of non-GAAP measures may not be comparable to other similarly titled measures of other companies.

The presentation of these financial measures is not intended to be considered in isolation or as a substitute for, or superior to, financial information prepared and presented in accordance with GAAP and should not be considered measures of QT Imaging's liquidity. Investors are cautioned that there are material limitations associated with the use of non-GAAP financial measures as an analytical tool. In particular, many of the adjustments to our GAAP financial measures reflect the exclusion of certain items, as defined in our non-GAAP definitions below, which are recurring and will be reflected in our financial results for the foreseeable future. In addition, these measures may be different from non-GAAP financial measures used by other companies, even where similarly titled, limiting their usefulness for comparison purposes and therefore should not be used to compare QT Imaging’s performance to that of other companies. We endeavor to compensate for the limitation of the non-GAAP financial measures presented by also providing the most directly comparable GAAP measures and descriptions of the reconciling items and adjustments to derive the non-GAAP financial measures.

We believe these non-GAAP financial measures provide investors and analysts with useful supplemental information about the financial performance of our business, enable comparison of financial results between periods where certain items may vary independent of business performance, and allow for greater transparency with respect to key measures used by management to operate and analyze our business over different periods of time.

EBITDA is defined as loss before interest expense, income tax expense, depreciation and amortization. Adjusted EBITDA is defined as EBITDA further adjusted for stock-based compensation, net change in fair value of the derivative, earnout and warrant liabilities, transaction expenses, warrant modification expense, loss on debt extinguishment, debt issuance expense and other income (expense), net. Similar excluded expenses may be incurred in future periods when calculating these measures. QT Imaging believes these non-GAAP measures of financial results provide useful information to management and investors regarding certain financial and business trends relating to the Company’s financial condition and results of operations. QT Imaging believes that the use of these non-GAAP financial measures provides an additional tool for investors to use in evaluating projected operating results and trends and in comparing QT Imaging’s financial measures with other similar companies, many of which present similar non-GAAP financial measures to investors.

Management does not consider these non-GAAP measures in isolation or as an alternative to financial measures determined in accordance with GAAP. The principal limitation of these non-GAAP financial measures is that they exclude significant expenses and income that are required by GAAP to be recorded in the Company’s condensed consolidated financial statements. In addition, they are subject to inherent limitations as they reflect the exercise of judgment by management about which expense and income items are excluded or included in determining these non-GAAP financial measures.

Management uses EBITDA and Adjusted EBITDA as a non-GAAP performance measure that is defined in the accompanying tables and is reconciled to net loss, the most directly comparable GAAP measure, in the tables below.

We present reconciliations of these non-GAAP financial measures to the most directly comparable GAAP measures in the tables below.
