Thomas Teisseyre, Chief Operating Officer of Hyperfine, Inc. (NASDAQ:HYPR), sold 24,188 shares of Class A common stock on March 23, 2026, as documented in a Form 4 filing with the Securities and Exchange Commission. The shares were sold at $1.21 apiece, producing a total transaction value of $29,267.
Following the disposition, Teisseyre’s direct holdings in Hyperfine stand at 354,648 shares. The filing specifies the purpose of the sale: to cover tax withholding obligations tied to the vesting of restricted stock units that were granted on March 31, 2025. The Form 4 provides a formal record of the transaction and the stated reason for the sale.
At the time of the filing, Hyperfine’s shares were trading at $1.17, a level that reflects a decline of roughly 9.5% over the prior week. Separately, analysis from InvestingPro indicates that the company appears undervalued at current levels based on its Fair Value assessment.
The insider transaction arrives against a backdrop of improving company performance. Hyperfine reported fourth-quarter and full-year 2025 results that exceeded expectations, including revenue growth that topped analysts’ projections and a smaller-than-anticipated loss per share. Those outcomes were highlighted by Lake Street, which raised its price target on Hyperfine to $2.50 from $2.00 and maintained a Buy rating.
Lake Street characterized the quarter as a turning point for the company, describing the results as evidence of a transition to what it calls "Hyperfine 2.0" - an emphasis on execution with accelerating revenue growth and improving gross margins. According to the firm, the shift marks a movement away from a research-and-development posture toward one focused on operational execution.
Investors tracking insider activity, company fundamentals, and analyst revisions may view the sale and recent quarterly performance as related but distinct developments: the restricted stock unit vesting prompted a tax-related disposition by an executive, while the reported results and analyst commentary speak to the company’s recent operating trajectory.
