Reviewed listing: XETR:STO3 · Analysis dated Oct 29, 2026
It has not been confirmed whether the basis of this analysis still holds today. Read it as a dated earlier assessment; it does not establish a current buying opportunity.
How does the company make money?
For example, Sto makes insulation materials and coatings for facades, as well as plaster and paint products for interiors. The company makes money by selling these construction materials and systems internationally.
What supports the business?
In the first half of 2026, Sto's earnings before interest and taxes rose to 30.5 million euros, compared with 25.3 million in the prior-year period. The improvement came despite a difficult construction market.
What could improve?
The interiors business performed well, and Sto gained market share in some weak markets. If this continues and the construction economy does not deteriorate further, the business result could benefit.
How is the stock price assessed?
This assessment refers to the analysis and its quoted price shown here. It is not a live quote or a personal recommendation to buy.
At 105.80 euros per preferred share, the price cannot be reliably assessed as cheap or expensive based on the verified business figures. The half-year result alone is not enough to establish a sound price limit.
What is the main risk?
Cash outflow from ongoing operations was 19.2 million euros in the first half, following an outflow of 0.7 million in the prior year. Higher procurement and freight costs, as well as pricing pressure, could put further pressure on profits.
What is the overall assessment?
Sto increased revenue and operating income in the first half of 2026, but cash flow from operating activities deteriorated significantly. Cost and pricing pressures remain important risks, and the specified price cannot be assessed reliably; therefore, the overall risk-reward profile is not yet compelling.
