EDEN PRAIRIE, MN, August 8, 2025 (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 ended June 30, 2025.

Quarter ended June 30, 2025

•Revenue for the three months ended June 30, 2025, totaled $10.2 million, an increase of 42%, as compared to $7.2 million for the same period of 2024. This growth was within the Company's guidance of growth of 40-50% year on year for the quarter.
•116 UltraMist® systems were sold in Q2 2025 up from 72 in Q2 2024, and from 98 in Q1 2025.
•UltraMist® consumables revenue increased by 37% to $6.4 million in Q2 2025, versus $4.7 million for the same quarter last year. UltraMist® revenue represented 99% of Sanuwave’s overall revenues in Q2 2025.
•Gross margin as a percentage of revenue amounted to 78.3% for the three months ended June 30, 2025, versus 73.2% for the same period last year.
•For the three months ended June 30, 2025, operating income totaled $1.9 million, compared to $2.0 million in Q2 2024. Q2 2025 operating expenses included $1.1 million of stock compensation expenses versus $0 in the same period in 2024.
•Net income for the second quarter of 2025 was $1.1 million. This compares to a net income of $6.6 million in the second quarter of 2024 which was primarily driven by a $5.3 million gain on extinguishment of debt that did not recur during the three months ended June 30, 2025 and the change in the fair value of derivative liabilities.
•Adjusted EBITDA [1] for the three months ended June 30, 2025, was $3.4 million versus Adjusted EBITDA of $1.5 million for the same period last year.

“We’re pleased to have put up strong results for Q2 and to have achieved 51% revenue growth in the first six months of 2025 vs the same period in 2024 ,” said Morgan Frank, CEO. “We sold 214 UltraMIST systems in the first six months of this year, more than we did in the full year of 2023 and an increase of 86% versus same period in 2024. Q1 and Q2 have been spent building and reshaping our sales and commercial operations teams, and as of mid July, the Company achieved


full national sales coverage for the first time in my tenure as CEO. If Q1 and Q2 were the quarters of “max disruption” Q3 is expected to be the quarter of “max construction” as the Company builds up momentum around our new sales and marketing practices (including the launch of our first concerted marketing program) with an aim to set us up for breakout performance in Q4 2025 and 2026. The energy at our sales and commercial operations national meeting a couple of weeks ago was palpable. I think we’re all looking forward to seeing what Sanuwave can become as it starts firing on all cylinders.”

Financial Outlook

The Company forecasts Q3 2025 revenue of $12-$12.7 million and reiterates full year 2025 revenue guidance of $48-$50 million (47-53% increase as compared to full year 2024 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”) and Adjusted EBITDA 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. EBITDA and Adjusted EBITDA should not be considered as alternatives to net income (loss) 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 and Adjusted EBITDA 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. 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).

Forward-Looking Statements

This press release may contain “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995, such as statements relating to future financial results, production expectations, and plans for future business development activities. Forward-looking statements include all statements that are not statements of historical fact regarding intent, belief or current expectations of the Company, its directors or its officers. Investors are cautioned that any such forward-looking statements are not guarantees of future performance and involve risks and uncertainties, many of which are beyond the Company’s ability to control. Actual results may differ materially from those projected in the forward-looking statements. Among the key risks, assumptions and factors that may affect operating results, performance and financial condition are risks associated with regulatory oversight, the Company’s ability to manage its capital resources, competition and the other factors discussed in detail in the Company’s periodic filings with the Securities and


Exchange Commission. The Company undertakes no obligation to update any forward-looking statement, except as may be required by applicable law.
