Rhea-AI Filing Summary

ALPS Advisors, Inc. and the Alerian MLP ETF filed an Amendment to Schedule 13G reporting shared beneficial ownership of common units of Hess Midstream LP. ALPS Advisors reports beneficial ownership of 12.75% of the class, equal to 29,295,245 units, while Alerian MLP ETF reports 12.6%, equal to 28,950,810 units. Both filers state they have no sole voting or dispositive power and instead report shared voting and dispositive power over the listed amounts. The filing clarifies that ALPS Advisors acts as an investment adviser to funds that own the securities and disclaims direct beneficial ownership, and that the holdings are managed in the ordinary course of business and not for the purpose of changing control.

Positive

• Transparent disclosure of ownership percentages (12.75% and 12.6%)
• Adviser disclaimer clarifies holdings are owned by funds, not directly by the adviser
• No indication of intent to influence or change control; holdings characterized as ordinary-course management

Negative

• High concentration: each filer holds >12%, which could concentrate voting influence
• Shared voting power reported for large stakes, reducing clarity about ultimate voting decisions

Insights

Investment Adviser Compliance Analyst

Reported fund holdings show material passive stakes without control intent.

The filing shows an investment adviser (ALPS Advisors) and one of its advised funds (Alerian MLP ETF) collectively holding over 12% stakes each in the same equity class, with voting and dispositive power reported as shared. This structure is common when an adviser manages ETF positions and signals substantial passive exposure to the issuer.

Key dependencies include whether the positions represent index tracking or active strategy implementation; the filing explicitly states the holdings are managed in the ordinary course and not to change control. Monitor periodic filings for quarterly updates and any Schedule 13D filings that would indicate a change in intent or activism within short regulatory timeframes.

ETF Portfolio Strategist

ETF-level stake of 12.6% is a sizable passive holding for investors to note.

The Alerian MLP ETF reports ownership of 28,950,810 units representing 12.6% of the class, which is large enough to affect trading liquidity and index-weighted exposures for MLP-focused products. Since the ETF is an investment company, its holdings disclose concentration but not the identity of underlying shareholders.

Watch subsequent Form 13G/A or 13D filings and fund disclosures for any change in position size or voting policy within the next reporting cycle that could alter passive-market dynamics.
