SANUWAVE HEALTH REPORTS SECOND QUARTER FINANCIAL RESULTS

AND PROVIDES A BUSINESS UPDATE

ALPHARETTA, GA, August 6, 2014 – SANUWAVE Health, Inc. (OTCQB: SNWV) today reported financial results for the three and six months ended June 30, 2014 and provided a business update. The Company will host a conference call on Thursday, August 7, 2014, at 11:00 a.m. Eastern Time.

Highlights of the second quarter and recent weeks include:

“We achieved a significant milestone for SANUWAVE in the second quarter with the 90th patient being enrolled in the dermaPACE clinical trial and now having completed the 12 week efficacy assessment period,” stated Kevin A. Richardson, II, Chairman of the board of directors. “We anticipate having the feedback from the Data Monitoring Committee regarding the first 90 patients in September and look forward to updating shareholders at that time. We have continued to enroll patients in the dermaPACE^® clinical trial for treating diabetic foot ulcers and remain focused on completing the trial as soon as possible to address this $3 billion market opportunity in the United States.”

“In addition, our technology platform includes 38 issued and pending patents, and finding additional strategic partners, such as Premier Shockwave, to help us monetize and advance new uses for our technology covered by these patents into other verticals and applications, including stem cells, is very important for us to achieve our ultimate goal, which is to maximize shareholder value,” concluded Mr. Richardson.

Second Quarter Financial Results

Revenue for the three months ended June 30, 2014 was $238,115, compared to $160,617 for the same period in 2013, an increase of $77,498, or 48%. The increase in revenue for 2014 was due to higher sales of orthoPACE devices in 2014 in Asia/Pacific, as compared to the prior year, as well as higher sales of refurbished applicators in Europe.

Research and development expenses for the three months ended June 30, 2014 were $1,013,652, compared to $624,533 for the same period in 2013, an increase of $389,119, or 62%. Research and development expenses increased in 2014 as a result of the clinical study starting the more costly enrollment phase in June 2013.

General and administrative expenses for the three months ended June 30, 2014 were $694,402, as compared to $1,157,119 for the same period in 2013, a decrease of $462,717, or 40%. The decrease in general and administrative expenses is primarily due to reduced stock-based compensation expense for 2014 due to the forfeiture of non-vested stock options by a terminated employee in 2014.

Net loss for the three months ended June 30, 2014 was $1,693,650, or ($0.03) per basic and diluted share, compared to a net loss of $818,331, or ($0.04) per basic and diluted share, for the same period in 2013, an increase in the net loss of $875,319, or 107%. The increase in the net loss was primarily a result of the one-time non-cash gain of $2,328,000 in other income in 2013 for the embedded conversion feature of the Senior Secured Notes which were converted to equity in the third quarter of 2013, offset by accrued interest expense on the Senior Secured Notes.

Net loss for the six months ended June 30, 2014 was $4,257,604, or ($0.10) per basic and diluted share, compared to a net loss of $6,187,664, or ($0.29) per basic and diluted share, for the same period in 2013, a decrease in the net loss of $1,930,060, or 31%.
