Goldan purchased 1,226 common shares on 07/31/2025 under the company’s Employee Stock Purchase Plan (ESPP) at an average price of $8.43 per share. The transaction is coded “J,” confirming it is part of a tax-qualified plan rather than an open-market buy.
Following the purchase, Goldan’s direct ownership rises to 93,676 shares. No derivative securities were reported. The filing was submitted on 08/07/2025 and signed by attorney-in-fact Michael A. Metzger.
The acquisition is modest in dollar terms (≈$10 k) but represents incremental insider buying, which can be interpreted as a signal of management confidence. However, the size relative to Goldan’s total stake and SNDX’s share count suggests limited market impact.
