The building season — CHF 11.5bn by September, at 93%.

93% probability Holcim's nine-month 2026 net sales reach at least CHF 11.5bn. The first half delivered CHF 7.9bn with 5.2% organic growth, recurring EBIT rose 11.5% organically, and management upgraded full-year guidance. Q3 is the Northern Hemisphere construction peak.

— 1 · The Locked Call

Holcim's nine-month 2026 net sales are at least CHF 11.5bn — P = 0.93.

We lock a binary: Holcim's reported net sales for the nine months to 30 September 2026 are CHF 11.5bn or higher. Confidence 93%.

The first half is already banked at CHF 7.9bn. The threshold therefore asks Q3 alone to contribute CHF 3.6bn. That is a low bar for a quarter that contains the Northern Hemisphere construction peak, against a first half that averaged CHF 3.95bn per quarter including a seasonally weak Q1.

— 2 · Cement was a hole in the series

We had no building materials lock at all. This closes it with the metric management guides on.

The series carries locks on power, mining, pharma, software, banking, autos and consumer goods. Cement and aggregates, one of the largest and most cyclically informative industrial sectors in the world, had nothing. Holcim closes it, and closes it on a company that has just upgraded guidance rather than one that is limping.

One structural note that matters for anyone checking our base against older figures: Holcim separated its North American business in 2025, so the CHF 7.9bn first half is the continuing group, not the pre-separation whole. The guidance upgrade was issued on that same continuing basis, which is why the two are comparable here and why comparisons to pre-2025 revenue lines are not.

The residual 7% is almost entirely the Swiss franc. Holcim reports in CHF while earning across the euro area, Latin America and Asia, so a sharp franc appreciation compresses reported net sales even when volumes and organic growth hold. That is the realistic path to a miss, and it is the reason the floor sits roughly 7% below our central expectation rather than 2%.

Binary: YES if Holcim's reported nine-month 2026 group NET SALES are CHF 11.5bn or greater; NO if below. Net sales as reported in Swiss francs for the continuing group — NOT recurring EBIT, NOT organic growth percentages, and NOT a constant-currency or like-for-like restatement. We take the published CHF figure and apply no FX adjustment of our own.

Q3 need only add CHF 3.6bn to a first half that averaged CHF 3.95bn a quarter, in the strongest construction quarter of the year. The realistic path to NO is franc appreciation, not demand.
