Thank you, Morgan. Good morning, everyone. I'm pleased to have joined the SANUWAVE team just a short 6 weeks ago, and I'm very excited to contribute to the team's continued growth and strategic initiatives. With that, here's a look at the numbers.
Revenue for the 3 months ended March 31, 2024, totaled $5.8 million, an increase of 53% as compared to $3.8 million for the same period of 2023. This growth is within the previous guidance range of 45% to 55%. Gross margin as a percentage of revenue amounted to 73% for the 3 months ended March 31, 2024, versus 67% for the same period last year. For the 3 months ended March 31, 2024, operating loss totaled $1.1 million, which is an improvement of $928,000 compared to the same period last year, which aligns with our continued initiative to drive towards profitable growth and manage spend effectively.
Operating expenses for the 3 months ended March 31, 2024, amounted to $5.3 million compared to $4.5 million for the 3 months ended March 31, 2022, an increase of $761,000 due to a couple of nonrecurring charges related to litigation charges and a charge for severance agreement.
Net loss for the 3 months ended March 31, 2024, was $4.5 million compared to a net loss of $13.1 million for the same period in 2023. The decrease in net loss was primarily due to a change in the fair value of derivative liabilities, interest expense and somewhat offset by the receipt of $2.5 million related to the license and option agreement.
Adjusted EBITDA for the 3 months ended March 31, 2024, was close to breakeven at a $59,000 loss versus a $1.8 million loss for the same period last year, an improvement of $1.7 million. SANUWAVE continued to execute its financial strategy to improve operational profitability and manage operating expenses. Total current assets amounted to $10.8 million as of March 31, 2024, versus $9.8 million as of December 31, 2023. Cash totaled $2.9 million as of March 31, 2024.
We thank you for the continued support of SANUWAVE. And with that, I'll now transfer the call back to Morgan.
