EDEN PRAIRIE, Minn., March 26, 2026 (GLOBE NEWSWIRE) — Sanuwave Health, Inc. (the “Company” or “Sanuwave”) (NASDAQ: SNWV), a leading provider of next-generation FDA-approved wound care products, is pleased to provide its financial results for the three months and full year ended December 31, 2025.

Q4 2025 ended December 31, 2025

Revenue for the three months ended December 31, 2025, totaled $13.4 million, an increase of 29.7%, as compared to $10.3 million for the same period of 2024. This growth is consistent with guidance of $13-14 million for the quarter.
255 UltraMist® systems were sold in Q4 2025 up from 135 in Q4 2024 and from 155 in Q3 2025.
UltraMist® consumables revenue increased by 10.6% to $6.5 million in Q4 2025, versus $5.9 million for the same quarter last year. Consumables revenue represented 48.7% of overall revenues in Q4 2025. UltraMIST systems and consumables remained the primary revenue growth driver for the Company and represented approximately 100% of Sanuwave’s overall revenues in Q4 2025.
Gross margin as a percentage of revenue amounted to 74.7% for the three months ended December 31, 2025, versus 77.9% for the same period last year. Cost of revenues included a $486 thousand write-off of PACE inventory associated with the sunsetting of that product line. Absent this charge, gross margin would have been 78.3%.
For the three months ended December 31, 2025, operating income totaled $2.0 million, no change, compared to Q4 2024. Q4 2025 included the inventory write off of $486 thousand which affected cost of revenues and a sales tax expense of $479 thousand which increased general and administrative expenses. Absent these charges, operating income would have been $3.0 million.
Net income for the fourth quarter of 2025 was $7.7 million, driven predominantly by the change in the fair value of derivative liabilities. This compares to a net loss of $13.3 million in the fourth quarter of 2024 which was primarily driven by the change in the fair value of derivative liabilities, valuation adjustments resulting from the share and warrant exchange, and the extinguishment of debt.
Adjusted EBITDA [1] for the three months ended December 31, 2025, was $4.8 million versus Adjusted EBITDA of $3.7 million for the same period last year, an improvement of $1.1 million.

Full year 2025 ended December 31, 2025

Revenue for the year ended December 31, 2025, totaled $44.1 million, an increase of 35.0%, as compared to $32.6 million for the same period of 2024. This growth was in line with full year guidance of growth of 35-39% year on year.
624 UltraMist® systems were sold in 2025 up from 374 in 2024.
UltraMist® consumables revenue increased by 27.4% to $25.5 million (58.0% of revenues) in 2025, versus $20.1 million for the same period last year. UltraMIST systems and consumables remained the primary revenue growth driver and continued to represent over 99% of Sanuwave’s overall revenues in 2025.
Gross margin as a percentage of revenue amounted to 77.1% for the year ended December 31, 2025, versus 75.2% for the same period last year.
For the year ended December 31, 2025, operating income totaled $4.9 million, an increase of $1.1 million compared to 2024 as a result of the Company’s continued efforts to drive profitable growth and manage expenses.
Net income for 2025 was $11.8 million, driven predominantly by the change in the fair value of derivative liabilities, other income, and increased operating profit. This compares to a net loss of $33.1 million in 2024 which was primarily driven by the change in the fair value of derivative liabilities.
Adjusted EBITDA [1] for the twelve months ended December 31, 2025, was $13.6 million versus Adjusted EBITDA of $7.2 million for the same period last year, an improvement of $6.5 million.

“We’re pleased to be, once more, announcing an all-time record quarter for Sanuwave on both revenues and adjusted EBITDA, especially during such challenging times in the wound care space,” said CEO Morgan Frank. “The effects of the CMS reimbursement cut to skin substitutes and an intensification of the CMS audit environment have been dramatically reshaping a number of sectors of wound care, particularly mobile care. Q4 2025 saw the first major reactions to the new pricing with large numbers of mobile wound care providers exiting the space and/or cutting staff. At the same time, we have seen other existing companies and a great many new ones gearing up to enter. It seems very much to be a ‘one tide going out while another tide is coming in’ sort of moment for the space and, while such transitions are inevitably choppy, it seems like a lot of this change will ultimately flow our way. The patients and the wounds have not gone away and neither has the need for care. UltraMIST remains a potent solution ready made for the work and business flow of our customers and the needs of those they care for. Significant numbers of large, skilled distributors and resellers who had been focusing on skin subs and allografts have become interested in repping UltraMIST and we have taken advantage of this new option to dramatically increase our functional number of feet on the street. These gains in Q4 2025 were somewhat offset by lower consumables sales resulting from a confluence of some customers going out of business and others reducing patient volumes in response to an aggressive audit environment. CMS appears to have made a determination to focus heavily on medical necessity and value for money in the wound care space and while this has created a bit of a stutter step in the short run, we see it as a trend that should be long term beneficial to us. We remain more convinced than ever of the potential for this product to help transform wound care.”

Financial Outlook

The Company forecasts Q1 2026 revenue of $9.6 to $10.3 million (3-10% increase from Q1 2025) and initiates full year 2026 revenue guidance of $51.0-55.0 million (16-25% increase as compared to full year 2025 revenue).

Non-GAAP Financial Measures
This press release includes certain financial measures that are not presented in our financial statements prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”). These financial measures are considered “non-GAAP financial measures” and are intended to supplement, and should not be considered as superior to, or a replacement for, financial measures presented in accordance with U.S. GAAP.

The Company uses Earnings Before Interest, Taxes, Depreciation and Amortization (“EBITDA”), Adjusted EBITDA, Adjusted Gross Margin Percentage and Adjusted Operating Income to assess its operating performance. Adjusted EBITDA is Earnings before Interest, Taxes, Depreciation and Amortization adjusted for the change in fair value of derivatives and any significant non-cash or infrequent charges. Adjusted Gross Margin Percentage is gross margin percentage adjusted for inventory write-off. Adjusted Operating Income is operating income adjusted for inventory write-off, sales tax expense and release of historical accrual. EBITDA, Adjusted EBITDA, Adjusted Gross Margin Percentage and Adjusted Operating Income should not be considered as alternatives to net income (loss), gross margin percentage or operating income, as applicable, as a measure of financial performance or any other performance measure derived in accordance with U.S. GAAP, and they should not be construed as an inference that the Company’s future results will be unaffected by unusual or infrequent items. These non-GAAP financial measures are presented in a consistent manner for each period, unless otherwise disclosed. The Company uses these measures for the purpose of evaluating its historical and prospective financial performance, as well as its performance relative to competitors. These measures also help the Company to make operational and strategic decisions. The Company believes that providing this information to investors, in addition to U.S. GAAP measures, allows them to see the Company’s results through the eyes of management, and to better understand its historical and future financial performance. These non-GAAP financial measures are also frequently used by analysts, investors, and other interested parties to evaluate companies in our industry, when considered alongside other U.S. GAAP measures.

EBITDA, Adjusted EBITDA, Adjusted Gross Margin Percentage and Adjusted Operating Income have their limitations as analytical tools, and you should not consider them in isolation or as a substitute for analysis of the Company’s results as reported under U.S. GAAP. For example, some of these limitations are that EBITDA and Adjusted EBITDA:

Do not reflect every expenditure, future requirements for capital expenditures or contractual commitments.
Do not reflect all changes in our working capital needs.
Do not reflect interest expense, or the amount necessary to service our outstanding debt.

As presented in the U.S. GAAP to Non-GAAP Reconciliations section below, the Company’s non-GAAP financial measures exclude the impact of certain charges that contribute to our net income (loss), gross margin percentage and operating income, as applicable.
