Funds holding the stock by quarter

Q1 2026	1	—	0	$0
Q2 2026	5	+4	127,288	$190.3K
Q3 2026	4	-1	49,300	$41.4K

Each point is a quarter-end, from Q1 2026 to Q3 2026. A fund's 13F lists its long positions in US-listed securities as of the last day of the quarter and arrives up to 45 days later, so each point shows holdings at quarter-end, not on the day they were reported.

Common shares only; options and bonds are left out. When a fund amends a report, the amended version is the one counted.

The history follows the company's current CUSIP number (G2124G203). If the company's shares were ever re-issued under a different CUSIP, the quarters before the change are not part of this series, so the first point (Q1 2026) can be later than the stock's first appearance in 13F reports.

Share counts are adjusted for stock splits (1-for-150 on Apr 8, 2026): reports from before a split are multiplied by its ratio, so every quarter is on the share count of Q3 2026.

A quarter appears once our daily update has built its summary. If a summary cannot be built, older reports are kept and the chart shows the quarters it has until the next update repairs it.
