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.

Dividends: $70.7M

What drove EPS

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

FY23

71.5% = 71.8% + −0.2%

FY24

−25.1% = −25.1% + −0.0%

FY25

11.5% = 12.9% + −1.2%

Earnings Fewer shares More shares

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.
