Insights
Newtyn is a visible holder with single-digit ownership and full voting/dispositive power.
Newtyn Management is reported to beneficially own 11,600,000 shares, equal to 8.1% of the Class A common stock based on a 143,870,326 share base as of February 27, 2026. The filing attributes sole voting and dispositive power to Newtyn Management over the aggregate holdings.
The position size is below typical takeover thresholds but is large enough to register as a notable institutional stake. Subsequent filings may show changes; any shifts in voting disposition or additional purchases/sales would materially change influence.
Reported sole voting/dispositive power centralizes control of the combined stake under the manager.
The report states Newtyn Management "may be deemed to beneficially own" the combined 11,600,000 shares because it is investment manager to two related partnerships. The filing discloses sole voting power and sole dispositive power for that aggregate amount.
The submission includes a Joint Filing Agreement dated March 25, 2026. Governance watchers should note the managerial attribution; any material changes to holdings or voting arrangements would be disclosed in future Section 13 filings.
