Revenue for continuing operations recognized for the reporting period is as follows:

In the same period of the prior year, revenue from activities previously allocated to the Water Management business - which was classified as a discontinued operation - was reallocated to IA as those activities were not part of the divestiture. This concerns revenue in the amount of EUR 8,444 thousand. 

In addition, revenue incurred between the continuing operation and the discontinued operation up to the time of disposal in the amount of EUR 1,312 thousand (H1 2025: EUR 6,891 thousand) was allocated to IA.

Sales revenues are broken down into categories as follows:

Other sales revenues mainly include proceeds from the sale of no longer used production residues from metal production.

Revenues for the first six months of 2026 include “income” from the reversal of refund liabilities recorded in the previous period in the amount of EUR 989 thousand (H1 2025: EUR 171 thousand). The reversals represent the difference between the expected volume discounts and annual bonuses for customers recorded as of December 31, 2025, and the actual payment in the fiscal year, as well as the differences from recorded deferred revenue from price negotiations with NORMA Group customers that were not concluded in the prior year.

Excluding changes in inventories, the cost of materials as a percentage of revenue was 43.6% (H1 2025: 46.0%), below the level in the corresponding prior-year period. The cost of materials as a percentage of total operating performance was 43.6% (H1 2025: 45.6%), likewise below the level in the corresponding prior-year period.
