Fair value · TENARIS SA (TS) · updated 2026-09-10 · from 20-F FY2025
TENARIS SA trades at $56.80. We are not reading assumptions out of that price: our price is for one ADS, which represents 2 ordinary shares, but this company files its per-share figures per ordinary share — so these methods need a per-share restatement we do not yet publish.
Everything below is unaffected: the filed statements, the filing they came from, and TS’s growth history are all as reported.
At least two methods need a usable value to draw a range with these inputs.

The two ranges are identical because every input sits on a preset.
We don’t tell you what TS is worth. Every tab OPENS on what today’s price implies for that method’s key assumption; you decide whether that assumption is reasonable — the growth matrix has TS’s filed history and the AI chat will reason it through with you — and the range you build is yours. Our presets are filed history and reference settings, never a recommendation.
