Corporate Governance Expert

TL;DR This Schedule 13G/A signals a sizable passive stake (8.24%) and confirms no declared intent to change issuer control.

The amendment clarifies Primecap's stake and voting/dispositive authority without indicating activist intent. The explicit certification that the shares were not acquired to influence control is important for governance assessment: it frames the holding as passive under the Schedule 13G framework. While the stake exceeds the 5% reporting threshold and is material, the filing contains no proposals, arrangements, or group affiliations that would suggest governance action.
