Insights

Financial Analyst

TL;DR: LMR holds a passive, sub-5% stake of 941,287 shares (4.1%) via two master funds; shared power limits unilateral influence.

The disclosure shows LMR controls 941,287 Class A shares split between two master funds (590,644 and 350,643). Filing on Schedule 13G and the certification of ordinary-course acquisition signal a passive position rather than an active takeover intent. Because the stake is below 5% and voting/dispositive power is shared, this holding is material to record but unlikely to alone alter governance or trigger control thresholds.

Corporate Governance Expert

TL;DR: Reporting persons report shared voting/dispositive power over 941,287 shares and disclaim intent to influence control.

The filing identifies multiple LMR entities across jurisdictions and two individuals as the ultimate decision-makers. Itemized ownership shows no sole voting or dispositive power and confirms ownership is held for investment purposes. Items regarding group formation, >5% ownership, and parent/subsidiary acquisitions are marked not applicable or indicate 5% or less, aligning with a passive investor profile under Schedule 13G.
