Insights

Portfolio Manager

Janus Henderson reports a material 5.4% holding in TYRA via shared voting and dispositive power.

The filing discloses 2,856,290 shares and explicitly allocates shared voting and shared dispositive power to the reporting group while showing no sole voting or dispositive power. Crossing the 5% threshold triggers public reporting and signals a visible institutional position. The classification as IA, HC and the identification of investment-adviser subsidiaries clarify the channels through which the position is managed. On its face, the disclosure is a routine institutional ownership report rather than an indication of control actions.

Corporate Governance Expert

The Schedule 13G/A and attached power of attorney reflect centralized, compliant reporting by Janus Henderson subsidiaries.

The document names JHIUS, JHIUKL and JHIAIFML as indirect subsidiaries and includes a power of attorney granting authority to specific employees to file and amend U.S. disclosure forms. That structure supports coordinated compliance across entities and clarifies who may execute reporting obligations. The statement of shared voting and dispositive power is explicit and limits ambiguity about how the position is reported within the group.
