UAA — blockholders· UNDER ARMOUR INC
Everyone who has reported crossing 5% of this issuer inside the capture window — Schedule 13D (active intent, with its Item-4 purpose) and Schedule 13G (passive by rule) kept apart — each with its full amendment chain and, in the fold, the cover page's sole and shared voting and dispositive power per reporting person. Percents are each group's own as-filed figures and do not add up across filers: two filers can report the same shares.
The filer says it may seek to influence or change control, and states why in Item 4. Open the fold for each reporting person's voting and dispositive power.

Filed passively under Rule 13d-1(b) (qualified institution), (c) (passive investor) or (d) (exempt). A 13G filer is not an activist and files no purpose statement.

Voting is not disposition. Each reporting person's cover page splits its holding into VOTING power (sole / shared) and DISPOSITIVE power (sole / shared). Voting and dispositive totals are summed WITHIN a person only — never across persons, because a group's members report overlapping interests in the same shares and the filing's aggregate is not their sum. Where a person's voting total is below its reported aggregate, the difference is shares it reports beneficial ownership of with no voting power reported; it is shown as a gap, never as a second position.
Percent is as filed. Percent is the filing's own percent of class, as filed (0–100). It's the reporting group's figure — not summed across filers, not recomputed against shares outstanding, not rescaled. Share counts are as filed and never subtracted across filings (a split would make that meaningless); the only change we show is the change in the as-filed percent against the prior captured filing.
We never call an amendment “new”. A filing is 'first captured' when we hold nothing earlier for that company + filer. On an amendment that means the original predates our window, not that the position is new — so we never badge an amendment 'new,' even when the raw data says so.
Escalations. An escalation is a filer moving from a passive 13G to an active 13D on the same company — telling the SEC it may now seek to influence control. It's a lower bound: a 13G filed before our window began is invisible and never guessed. If the 13D leg is a 13D/A, an earlier 13D predates our window, so the crossing shown is the first one visible inside it, not necessarily the filer's first.
Parsed Schedule 13D/G XML (events.db schedule_13dg + schedule_13dg_persons). 13D = active intent; 13G filers report passively under Rule 13d-1(b) QII / (c) Passive / (d) Exempt and are never activists. Percents are the reporting group's own as-filed figures and are NOT additive across filers — two filers can report the same shares. Structured 13D/13G coverage starts December 2024 (SEC XML mandate).
