Funds holding the stock by quarter

Q4 2025	9	—	1.48M	$14.6M
Q1 2026	24	+15	5.06M	$50.5M
Q2 2026	27	+3	5.33M	$53.8M
Q3 2026	11	-16	3.00M	$30.4M

Each point is a quarter-end, from Q4 2025 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 (G9584S106). 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 (Q4 2025) can be later than the stock's first appearance in 13F reports.

Share counts are adjusted for stock splits; none took place between these quarters. Values are in dollars as reported at the time and are not adjusted.

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.
