Insights

Financial Analyst

Wasatch reports a material, passive 5.5% stake in CWST (3.41M shares).

The Schedule 13G discloses Wasatch Advisors' beneficial ownership of 3,412,123 Class A shares, equal to 5.5% of the class, with sole voting power over 2,630,150 shares and sole dispositive power over the full amount. Filing under Schedule 13G and the included certification indicate the position is held in the ordinary course and not intended to effect control. For investors, this registers Wasatch as a notable institutional holder without an expressed control agenda.

Corporate Governance Expert

Institutional stake disclosed as passive; voting and dispositive figures are clearly stated.

Wasatch Advisors is classified as an investment adviser and reports both voting and dispositive authorities: 2,630,150 shares with sole voting power and 3,412,123 with sole dispositive power. The filing's certification explicitly denies acquisition for control, consistent with a Schedule 13G passive disclosure. This is material from an ownership-transparency standpoint but does not, on its face, signal governance engagement or a control intent.
