Framework analysis

Verdict	Meaning
BUY	Positive purchase signal: the framework's buy requirements are met.
PASS	The company clears the framework's checklist or screen, but the framework does not produce a buy signal. For valuation frameworks this often means margin of safety is missing, insufficient, or unavailable; some screen-only frameworks have no intrinsic-value BUY state.
NEUTRAL	Neither a positive nor negative conclusion. It does not mean to hold an existing position.
FAIL	The company does not clear the framework's requirements.
Ranked	Ranked strategies do not use PASS: selected cohort is BUY, outside the cohort is FAIL, and unranked is NEUTRAL.

Current investor scores use trailing 12-month flows and the latest balance sheet where supported. Multi-year and EPS tests retain annual history; each framework shows its financial basis below. Intrinsic values use annual financials.

What drove EPS

A buyback raises earnings per share without the company earning more. This splits each year's change into the two.

FY23

−81.5% = −81.2% + −1.3%

FY24

−72.1% = −71.5% + −2.0%

Earnings Fewer shares More shares

The two parts do not sum exactly to the total — the difference is the cross-term, plus preferred capital where the company has any. It is left visible rather than distributed into the other two.

Share count is the denominator the filer used for diluted EPS, recovered as net income ÷ EPS — not the balance-sheet count, which is a point-in-time figure and would put the timing difference into this split. Years with a loss are omitted: a smaller share count makes a loss per share larger, so the decomposition inverts.

Latest TTM and quarters alongside annual years

TTM sums four consecutive quarters and uses the latest quarter-end balances. Quarter columns show three-month results; annual columns show full-year totals. Growth compares the same period a year earlier. EPS is not added for TTM; full-year ratios are blank for quarters.
