E/P = trailing-12-month diluted EPS / price at quarter end. E/P is the inverse of P/E and stays defined when earnings are negative.
Today's P/E sits at the 33 percentile of its own 3-quarter history (min 24.1, median 29.7, max 32.5; quarters with earnings only).

Memo
DIASORIN S.P.A. (DIA.MI). Latest full fiscal year: 2025; data up to 2025-12-31.
Figures computed from the financial statements: revenue 1.2 bn EUR in 2025; YoY growth 0.8%; net margin 13.0%; ROE 9.2%.
The estimated value range is 16.86–43.30 EUR per share (median of 2 methods, agreement: low); assumptions are illustrative. Against the central value of 27.96 EUR, the price of 82.18 EUR leaves a potential of -66.0% (value / price − 1) and a margin of safety of -194.0% (1 − price / value). The range is the median of the methods' low, central and high values, not a probability interval.
Insufficient data for a verdict (score weight coverage: 52.1% of at least 60%).
Text generated deterministically from the figures shown; no language model. Not investment advice.
What supports the thesis
- Net margin: 13.0%
- FCF conversion: 180.6%
- Interest coverage: 9.0x
- FCF yield: 6.4%
- Payout ratio (FCF): 22.6%
What contradicts it
- P/E (TTM): 28.8x
- Shareholder yield (distributions): 1.5%
- The price is above the estimated value range
- The valuation methods diverge
