Quanta Services, median P/E at fiscal year-end, 10 fiscal years (2016 to 2025), reported earnings, 5 of the years ex one-offs: 30.6.
Forward P/E: price divided by the analyst consensus for the first fiscal year that has not started yet. The current year carries special items from quarters already reported.

Quanta Services leads: 6 to 8 metric wins.

Group holding company: 6179 (24 %) consolidates subsidiaries in full but owns only the stated share. Revenue, EBITDA and margin ratios are therefore restated for its own shareholders; earnings per share, P/E and return on equity already were.

n/a = not meaningfully computable, for example with negative equity.
