• Full disclosure of aggregated holdings: 1,800,651 shares (5%)
• Clear certification that the holdings are not intended to influence control
• Detailed entity mapping showing ownership by funds, SPVs, GP entities, and the managing partner

Negative

• Concentration in grouped vehicles (largest sub-holder CRCM G SPV, LP: 937,153 shares, 2.6%) could create perception of concentrated exposure
• Filing notes rely on an outstanding share denominator from an SEC filing dated June 30, 2025, requiring updates if share count changes

Insights

Fund Ownership Analyst

CRCM and affiliated funds hold a consolidated 5% stake in Grail, a visible minority position.

The filings list multiple CRCM vehicles that together account for 5% of common stock, with the largest sub-holder at 2.6%. This structure is typical for investment managers allocating holdings across funds and SPVs while consolidating reporting for transparency.

Key dependencies include the 36,047,799 share denominator and the funds' internal allocation; investors should note the position size is below common control thresholds and was expressly declared not intended to influence control.

Regulatory Compliance Specialist

Filing appears to meet Schedule 13G disclosure requirements for passive holdings with required certifications.

The document is structured as an amendment to Schedule 13G and includes Itemized ownership rows, entity identifications, citizenship, and the certification that the securities were not acquired to influence control. Multiple entities and a natural person (Chun R. Ding) signed the filing on 10/06/2025.

Material facts to watch are any future amendments that change percent ownership above 5% or reclassification to Schedule 13D, which would indicate active intent; none are present in this filing.
