EDAP TMS Director David R. Horn Acquires Shares in Public Offering via ADSs

The Form 4 for Horn notes 'Net buy activity across all transactions in this Form 4,' indicating insider purchasing activity that spans more than just the single 10,000-share block.
The filing explains the mechanics of an underwritten public offering, where the underwriter commits to buying all offered shares upfront to reduce issuer risk and facilitate a rapid capital raise.
There are multiple related Form 4 filings (with identifiers 34e155709f1f, 093d97e99607, 926d3bcc076f, 7d121d25508f) describing the same insider activity, suggesting repetitive disclosures across separate documents.
The filings reiterate that ADSs provide a means for U.S. investors to own shares of a foreign issuer on U.S. exchanges, broadening access to EDAP TMS SA stock in the U.S. market.
Three directors at EDAP TMS SA bought a combined 85,000 shares on August 14, 2026, at $4.75 per share — a clear sign of insider confidence during a public stock offering. The purchases totaled roughly $403,750 and were tied to an underwritten public offering of American Depositary Shares, according to Quiver Quant and GuruFocus.
Director Lance Willsey led the buying with 50,000 shares, pushing the company's total reported shares to 1,291,780, GuruFocus reported. Directors David R. Horn and Fran Schulz each bought 10,000 shares, with Schulz's purchase growing her stake by 196%, Quiver Quant noted.
All three purchases happened on the same day at the same price. Lance Willsey bought 50,000 shares for roughly $237,500, according to GuruFocus. David R. Horn bought 10,000 shares for $47,500, and Fran Schulz also bought 10,000 shares for $47,500, per Quiver Quant. Together, the three directors spent about $403,750 of their own money.
For Schulz, the purchase was especially notable. Her 10,000 new shares grew her holdings by 196%, meaning she nearly tripled her stake in one transaction, Quiver Quant reported. Horn's filing noted 'net buy activity across all transactions,' suggesting he may have made additional moves beyond the single 10,000-share block.
The shares were sold through an underwritten public offering. In this type of deal, an underwriter — usually a bank — agrees to buy all the offered shares upfront. This removes risk for the company and helps it raise money quickly. The company gets its cash fast, no matter how the market reacts afterward.
The offering used American Depositary Shares, or ADSs. An ADS is a way for U.S. investors to buy stock in a foreign company on a U.S. exchange. Each ADS in this case represents one ordinary share of EDAP TMS SA, a French medical device maker. Ordinary shares come with voting rights and the potential to earn dividends.
At least four separate Form 4 filings were submitted around this offering. The filings carry identifiers 34e155709f1f, 093d97e99607, 926d3bcc076f, and 7d121d25508f. Form 4s are required when company insiders buy or sell stock. The overlap suggests each director filed separately, but the activity all links back to the same public offering.
Insider buying during a public offering is often seen as a positive signal. When directors put their own money in at the offering price, it shows they believe the stock is fairly valued — or even cheap. At $4.75 per share, these directors are on record betting that EDAP TMS has room to grow, according to Quiver Quant and GuruFocus.
