Option exercise brings Sanuwave an additional $5.0M cash for its intravascular shockwave patent portfolio.

The company indicates that a third-party licensee has exercised an option to acquire a portfolio of patents covering intravascular shockwave applications. This option stems from an agreement dated March 6, 2024, under which Sanuwave, Inc. had previously granted the licensee an exclusive license and the related purchase option in exchange for a one-time $2.5 million payment.

With the option exercise on August 21, 2025, the licensee has now made an additional $5.0 million cash payment to Sanuwave, Inc.
