Yoon William T 4

What Happened
William T. Yoon, Chief Legal Officer of Dropbox, disposed of shares in two ways: 16,124 shares were withheld to cover tax withholding related to vested restricted stock units (RSUs) on 2026-05-15 (value reported $422,449), and he sold 7,230 shares in open-market transactions on 2026-05-18 for approximately $199,338 (two weighted-average sales at $27.28 and $27.80). Combined proceeds/withholding value reported across these transactions is about $621,787. All transactions are disposals (sales/withholding), which are generally routine and do not, by themselves, indicate insider sentiment.

Context

• RSU withholding (code F) is a common administrative action when restricted shares vest; the company retains shares to cover taxes rather than the insider selling shares afterward — this is not a market sale driven by the insider.
• The open-market sales were executed under a pre-established 10b5-1 plan, which typically indicates pre-arranged, rule-compliant selling rather than opportunistic trading based on inside information.
• As with all insider filings, these are factual disclosures of transactions; they do not by themselves prove the insider’s view of the company’s prospects.
