Insights

Securities Compliance Counsel

Amendment reflects administrative disaggregation under SEC Release No. 34-39538.

The filing documents that Vanguard's internal realignment caused certain subsidiaries to report holdings separately, and as a result Vanguard reports 0 shares beneficially owned in Dorman Products Inc. The text cites SEC Release No. 34-39538 and the January 12, 2026 realignment.

From a compliance perspective, this is a routine disclosure correcting beneficial-ownership reporting lines; timing and formality are shown by the 03/26/2026 signature date.

Institutional Holdings Analyst

Operational change, not an economic trade signal; holdings are reported at the subsidiary level now.

The amendment states Vanguard no longer is deemed to beneficially own the securities held by certain subsidiaries; it therefore reports 0 shares for the parent entity. The filing clarifies that subsidiaries pursue the same investment strategies as before.

Investor interpretation: the entry signals a reporting shift rather than a disposition of shares; subsequent filings from the named subsidiaries will show actual holdings.
