Rhea-AI Filing Summary

The Form 4 filing discloses that Hannah A. Valantine, M.D., a director of BridgeBio Pharma, Inc. (BBIO), sold a total of 4,707 shares of BBIO common stock on 26-Jun-2025 at weighted-average prices ranging from $44.01 to $44.14 per share.

  • Direct holdings: Two separate sales of 876 shares (avg. $44.1099) and 1,542 shares (avg. $44.01) reduced Dr. Valantine’s direct ownership from 9,883 shares to 7,465 shares.
  • Indirect (spousal) holdings: Two sales of 398 shares (avg. $44.1263) and 1,891 shares (avg. $44.0303) lowered spousal indirect holdings from 2,687 shares to 398 shares.
  • Total remaining beneficial ownership: 7,863 shares (7,465 direct + 398 indirect).
  • The filing uses transaction code �S� indicating open-market sales. Weighted-average price ranges are provided; detailed price breakdowns are available upon request, per footnotes 1 and 2.

No derivative security transactions were reported. No 10b5-1 trading plan is indicated, and there are no acquisitions or option exercises in this filing.

The magnitude of the sale represents a partial reduction of the director’s position rather than a complete exit, and the company’s overall share count is unaffected. The information is limited to insider activity; it does not include operational or financial performance data.

Insights

TL;DR � Director trims stake by 4,707 shares at ~$44; modest size, neutral-to-slightly negative sentiment.

Dr. Valantine sold roughly 37% of her combined direct and indirect position (4,707 of 12,570 pre-sale shares) at market prices near $44. Because the transactions were open-market sales without an accompanying 10b5-1 plan, they can be interpreted as discretionary. While insider selling often raises caution flags, the dollar value (�$207k) is modest relative to BBIO’s daily trading volume and market capitalization. No derivatives were exercised or created, suggesting this is a straightforward liquidity event rather than a strategic repositioning. Overall impact on valuation is minimal, but the selling may carry a mildly negative signal for sentiment-sensitive investors.
