Schedule 13D/A: Viking entities disclose 9.1%–9.7% holdings in BridgeBio (BBIO)

Rhea-AI Filing Summary

Amendment No. 8 to a Schedule 13D reports updated beneficial ownership information for the common stock of BridgeBio Pharma, Inc. ("Common Stock"). Multiple Viking-related entities and individuals are disclosed as reporting persons. Percentage calculations are based on 191,168,504 shares outstanding as of July 29, 2025. The cover pages show key positions: Viking Global Investors LP reports shared beneficial ownership of 17,780,183 shares (9.3%); Viking Global Opportunities-related entities report shared holdings of 17,489,651 shares (9.1%); and three individuals (O. Andreas Halvorsen, David C. Ott and Rose S. Shabet) are each reported with shared beneficial ownership of 18,602,920 shares (9.7%). The filing states the funds used were investor capital and incorporates a Schedule of Transactions as Exhibit 99.8. No transactions since Amendment No. 7 are reported except those listed in Exhibit 99.8.

Insights

Financial Analyst

TL;DR: Significant disclosed stakes by Viking-affiliated funds and principals approach 10%, a material ownership position to note.

The filing consolidates beneficial ownership across multiple Viking entities and identifies shared voting and dispositive power exercised through investment managers and general partners. Percentages are calculated on 191,168,504 outstanding shares, with key figures: 17,780,183 shares (9.3%) for Viking Global Investors LP and 18,602,920 shares (9.7%) for certain individuals. This scale of holdings is material for shareholder composition and could affect shareholder dynamics. The source of funds is investor capital and a transactions schedule is provided as Exhibit 99.8. The disclosure is procedural and updates prior Schedule 13D amendments without adding new narrative objectives.

Corporate Governance Expert

TL;DR: Clear mapping of voting/dispositive authority among funds, managers and named executives clarifies who may influence corporate votes.

The amendment details which entities have authority to vote and dispose of shares and describes how VGI, VGP, VLFGP, Opportunities Portfolio GP and related managers may be deemed beneficial owners through their control relationships. It also confirms delegated signing authority for filings. These disclosures improve transparency about which parties hold shared control over substantial positions, which is important for board engagement and voting outcomes. The filing references Exhibit 99.8 for transaction detail and incorporates prior amendments.
