How much is Paolo Rocca Worth? Paolo Rocca Net Worth in 2026
Paolo Rocca’s net worth is estimated at $6.5 billion as of November 2026. For every $1 billion that Tenaris, the steel pipe maker he ran as CEO for 24 years, gains or loses in market value, his fortune moves by about $128 million. For the Milan-born Argentine-Italian executive, we value the fortune as a share of the family’s holding company, San Faustin, which controls Tenaris, Ternium and a string of private businesses.

How much is Paolo Rocca worth in 2026?
We estimate $6.5 billion. The key fact came out in July 2026: the Rocca family holds 39.7 percent of San Faustin’s capital and 51 percent of its votes, through a Dutch foundation, Milano Finanza reported. We split that equally between Paolo and his brother Gianfelice, then look through to what San Faustin owns. Euros are converted at 1.1228 dollars, the rate on November 10, 2026.
How we got to $6.5 billion
| Source | Our estimate | What it rests on |
|---|---|---|
| Tenaris, through San Faustin | $3.84 billion | Tenaris was worth $30.02 billion on November 9, 2026. The group holds 64.37 percent ($19.32 billion). His share is 19.85 percent of that: half of the family’s 39.7 percent of San Faustin. |
| Ternium, through San Faustin | $1.24 billion | Ternium was worth $10.05 billion on November 9, 2026. The group’s direct 62.02 percent is $6.23 billion; we take 19.85 percent. Tenaris’s own Ternium shares are already inside the Tenaris row. |
| Teur: Humanitas and Tenova | $0.86 billion | Our assumption: the Italian subholding is worth 10 times its 2025 EBITDA of 336.7 million euros plus 477.6 million euros of net cash, 3.84 billion euros or $4.32 billion, of which we take 19.85 percent. |
| Tecpetrol, engineering and other private units | $0.60 billion | Our assumption: $3 billion for the private businesses we found no figures for, of which we take 19.85 percent. |
| Total | $6.5 billion | The rows add to $6.54 billion. |
A fortune on a pipe
Our calculation: San Faustin’s 64.37 percent of Tenaris, times Paolo’s 19.85 percent share of San Faustin, means he owns the economic equivalent of about 12.8 percent of Tenaris. So each $1 billion swing in Tenaris’s value moves his net worth by about $128 million, and Tenaris alone makes up 59 percent of our total.
At the close we used, the stock was worth $30.02 billion. Tenaris had revenue of $11.98 billion in 2025, down from the year before. Ternium, the flat steel arm, was worth $10.05 billion that day, and the group’s direct 62.02 percent of it, plus Tenaris’s 11.46 percent, keeps it firmly in the family’s control.
Twenty-four years in the chair
He is the grandson of Agostino Rocca, who founded the group, and the son of Roberto Rocca. He studied political science in Milan, worked for an executive director at the World Bank and joined Techint in 1985 as an assistant to the chairman. He became CEO of Tenaris in 2002 and handed the job to Gabriel Podskubka in May 2026, staying on as chairman, according to his biography. He also chairs Ternium and Tamsa.
Why other estimates disagree
Most public estimates are higher. They tend to give each brother a bigger slice of San Faustin than a 39.7 percent family stake split two ways allows, or put a much higher price on the private businesses. Ours uses the July 2026 ownership figure and November 2026 share prices.
What would move the figure
The Tenaris share price does most of the work. A sale or listing of Tecpetrol or Humanitas would replace our two private-business assumptions with real prices. If other relatives own part of the family’s 39.7 percent, his share is smaller than half.
