Grupo Carso: Four Times the Profit on 4.6% More Sales — Three Old Drags Flipped at Once

Ixachi drilling and Saltillo construction turned from laggards into the growth engines, data-center cable ran hot at Condumex, and Panama still hasn't rained — but the Q&A was a blackout.

The arithmetic of a lopsided quarter

Conglomerates are supposed to be boring. Grupo Carso's third quarter of 2026 was not. “Grupo Carso sales totaled MXN 47.6 billion in the third quarter of 2026, increasing 4.6% compared with the same period of the prior year, despite the impact of the peso appreciation.” — Rafael Rogelio Barradas Servín, Unknown, likely an executive or investor relations representative · 2026-10-27 On that thin top line, “Operating income reached MXN 4.8 billion compared with MXN 3.2 billion in the third quarter of '25, representing an increase of 51.3%.” — Rafael Rogelio Barradas Servín, Unknown, likely an executive or investor relations representative · 2026-10-27 EBITDA rose 21.5% to MXN 6.8 billion, and net income attributable to the controlling interest hit MXN 2.6 billion against MXN 651 million a year earlier — roughly a four-fold increase. That gap between +4.6% sales and +51% operating income is the whole story of the print, and it is a mix story, not a volume story. Two of Carso's three biggest internal drags from earlier in the cycle reversed hard, and one got worse. What an investor needs to know is which is which. The audit caveat first: the net income bridge is not fully explained. The prepared remarks attribute the bottom-line leap to operating performance "together with the [indiscernible] in Central America" — a genuinely dropped word in the transcript. With a net swing of nearly MXN 2 billion, that missing word matters. Treat the reported net figure as directionally right and analytically incomplete.

What actually flipped

Zamajal and Ixachi. A year ago this division was the complaint: the prior keyword deck carried lower drilling activity in the first quarter of 2026 as an operating negative. In the third quarter, Zamajal sales went from MXN 546 million to MXN 3.0 billion on the back of the drilling services agreement with Pemex. The margin structure is the point: “Operating income reached MXN 736 million with a margin of 24.7%, while EBITDA totaled MXN 1 billion with a margin of 34.6%.” — Rafael Rogelio Barradas Servín, Unknown, likely an executive or investor relations representative · 2026-10-27 Management says eight wells have been delivered at Ixachi and two to four more are expected by year-end. A contracted, Pemex-anchored, high-margin service line is a very different asset from the idle onshore rigs described through 2025. Saltillo–Santa Catarina. The construction division's infrastructure segment posted 81% sales growth as the Saltillo-Santa Catarina train moved into construction. This directly retires the prior-quarter refrain of a drag from the conclusion of large infrastructure projects — the pipeline refilled, and backlog totaled MXN 36.9 billion as of September. A quieter new line: the jack-up rig leasing started during the quarter on a term exceeding one year, converting idle oil-service assets into contracted revenue. Condumex and the cable trade. Condumex sales rose 12.3% to MXN 14.9 billion, with the Cable division up 27.9%. The reason is the single most forward-looking sentence in the release:

Condumex sales increased 12.3% to MXN 14.9 billion, mainly driven by a 27.9% increase in Cable division sales, including, among others, cables for data centers together with higher exports.

That is a company riding a market wave rather than creating one. The global tape shows AI data center as a massive advancing cluster over twelve months (43 advancers versus 11 decliners) that has nevertheless de-rated over the last 90 days, with the optics and silicon sub-cluster — high bandwidth memory, co-packaged optics, PCIe lanes — down double digits recently. Carso's exposure is the copper-and-jacket layer, not the silicon. So the divergence is instructive: the equity market has cooled on AI infrastructure, while the physical cable pull-through at Condumex accelerated. Either the tape is early or the cable cycle is late. That is the debate, and the source of Condumex's cables for data centers momentum is the newest thing in this franchise. Elementia and Fortaleza. Sales fell to MXN 6.2 billion from MXN 7.6 billion on the El Salvador divestment, softer U.S. activity and FX translation — yet operating income rose to MXN 1.8 billion from MXN 1.1 billion. Revenue down, profit up 60%-plus, is a cost-and-mix print. Note that the Fortaleza Materiales disposal of 65% of Cementos Fortaleza El Salvador at an enterprise value of MXN 75 million is far too small to explain a swing of that size, so the improvement is structural, not one-off. Cement peers are saying similar things about price and cost this season.

What didn't flip

Carso Energy is the holdout. Revenue fell 19.1% to MXN 709 million, with operating income and EBITDA both down 20.5%, and the cause is unchanged from prior quarters: “power sales in Panama remained affected by lower water inflows associated with El Nino, a condition we expect to persist into next year.” — Rafael Rogelio Barradas Servín, Unknown, likely an executive or investor relations representative · 2026-10-27 This was already a named drag as lower electricity sales in Panama earlier in 2026. Importantly, the drought is not idiosyncratic: el niño ranked among the very top global themes across the market in the second quarter of 2026. Carso's Panama hydro problem is a weather market, and management has just told you it runs into next year. The peso is the second persistent headwind. peso appreciation and the stronger peso have appeared in the company's keyword deck repeatedly through 2026, and management again led the release by crediting the beat to operations "despite" FX. When a dollar-revenue segment like Carso Energy takes a 7.5% average-rate hit and cement takes translation losses, FX is doing real damage to reported numbers while underlying operations improve. Worth separating the two. And then the quiet one: Grupo Sanborns, at MXN 16.1 billion still Carso's largest division by sales, grew revenue just 1.4% on "subdued consumer spending as reflected in ANTAD indicators." An operating-income gain of 19.1% on that top line is impressive margin work, but Grupo Sanborns has slipped from the top of the narrative — a stark contrast with the fourth quarter of 2025, when it was the company's single most-highlighted theme. The rotation is the message: Carso's earnings engine has moved from retail and gas pipelines to industrial cable, Pemex drilling and cement margin.

The evidence problem

The Q&A is missing in action. “[Foreign Language] [The remainder of this transcript is in a foreign language]” — Unknown Analyst, Analyst · 2026-10-27 — and this is not new. The prior calls are archived the same way; even the operator script is one of the few usable English fragments: “The first question comes from [ Miguel Ochoa ].” — Rafael Rogelio Barradas Servín, Unknown, likely Investor Relations or Executive · 2026-02-10 Management answers arrive as placeholders. So there is no way to test the three questions that matter most: how much of the MXN 2.6 billion net income is recurring; whether the Elementia margin holds as U.S. volumes stay soft; and whether Condumex's cable order book extends beyond the current data-center build. First-quarter commentary from an earlier call is equally opaque: “[Foreign Language].” — Rafael Rogelio Barradas Servín, Unknown, likely Investor Relations or Executive · 2026-02-10 What you can underwrite is narrower and still real: a conglomerate whose 2026 drags — Ixachi drilling inactivity, concluded mega-projects, cement losses — have converted into three simultaneous tailwinds, against one weather-driven holdout and a persistent FX tax on reported revenue. The next checkpoints are the two-to-four Ixachi wells promised by year-end, conversion of the MXN 36.9 billion backlog, and rainfall in Panama. Everything else is a prepared remark.
