EPS and revenue as reported in this filer's own XBRL — our extraction of the filings, not a vendor consensus feed, and never a beat/miss claim (we carry no estimates). YoY compares the same fiscal quarter a year earlier. Next report 2026-08-06 is ESTIMATED from filing cadence (median gap 91d) — not company-confirmed.

Basis & disclosures

End-of-day only. Every price on this sheet is a stored CLOSE — the last one is 2026-07-28. Nothing here is live, intraday or delayed-real-time, and the sheet does not update after it is printed.
Nothing is imputed. A figure that is not in the underlying filing or feed renders as “—”. We never fill a gap with an estimate, a peer median or a carried-forward value.
Mixed as-of dates by design. Prices are at the last close; fundamentals are at the latest reported fiscal period; 13F ownership is at the latest filed quarter (45+ days in arrears); short interest is the latest FINRA settlement. Each block states its own basis above.
Not investment advice. Model fair values, reverse-DCF grades and confidence labels are the output of published, disclosed methods on public filings — they are analysis, not a recommendation, a price target or a solicitation.
Fundamentals and ownership derive from SEC EDGAR (and equivalent foreign registers); prices from a licensed end-of-day vendor, shown under a neutral source label. Full methodology at spzco.com/methodology.
