Both are AllianzIM funds, so the difference between them is the terms rather than the house.
Where each one stands today
SEPT resets first, on Aug 31, 2027, 345 days from now; SEPU runs to Aug 31, 2027, 345 days. A fall from here reaches SEPT’s buffer after 1.4% and SEPU’s after 1.4%. Both track SPY, so what separates them is where each is in its own period.
Every figure is ETFIQ’s own, from the issuer’s published outcome-period terms. A buffer ETF holds FLEX options on its reference index rather than shares, so there is no holdings overlap between two of them to report.
