Key Details

• Transaction date: 2026-08-19; Form 4 filed: 2026-08-21 (appears timely — two days after the trades).
• Reported prices: $14.00 reported as weighted-average; actual trade prices ranged $13.95–$14.15 (per filing).
• Total shares sold: 28,468; total proceeds: ~$398,552.
• Shares owned after transaction: not specified in the provided filing.
• Notable footnotes: sales were made pursuant to a Rule 10b5‑1 trading plan established April 8, 2026. The filing also notes the shares were held directly by Atlas venture funds (Atlas Venture Fund XI, L.P. and Atlas Venture Opportunity Fund II, L.P.) and the reporting person disclaims beneficial ownership except for any pecuniary interest.

Context
Sales under a 10b5‑1 plan are prearranged and often reflect scheduled disposals rather than real-time views on the company; filings also indicate these shares were held by affiliated venture funds (institutional interest), not necessarily sold as the director’s personal holdings. As always, insider sales are factual data points but do not on their own prove management sentiment.
