Legacy analysis: only the dimensions classifiable by the pre-v1 pipeline are shown.

Reported facts

GAAP facts are reported by the company. Comparable figures are EarnIQ arithmetic using only quantified adjustments disclosed in the linked SEC exhibit.

Earnings quality

From 10-Q / 10-K XBRL filings. Sloan (1996) accruals: high accruals relative to assets have historically preceded earnings disappointments. Descriptive research, not a prediction.

Earnings look cash-backed — accruals are -6.3% of assets, in the strongest quintile of large caps.
