Goins Melanie F 4

What Happened
Melanie F. Goins, General Counsel and Chief Product Officer of 1stdibs.com, had restricted stock units (RSUs) vest on March 9, 2026 and those RSUs converted to common shares. Of the vested shares (33,195 total), 9,745 shares were retained by the company to satisfy tax withholding, and 14,900 shares were sold in open-market transactions March 9–11, 2026 for aggregate proceeds of approximately $82,002 (sales executed at prices roughly $5.50–$5.56 per share). The conversions and withholding appear as derivative/settlement entries; the open-market sales were executed under a pre-established Rule 10b5-1 trading plan.

Context
These transactions reflect RSU vesting followed by net tax withholding and planned open-market sales under a 10b5-1 program. That sequence (vesting → withholding → pre-arranged sale) is a common, administrative insider transaction and does not by itself indicate a change in the insider’s view of the company. The filing was timely.
