Rational AG (ISIN DE0007010803) closed at EUR 578.50 on Xetra on September 21, 2026, up 0.26 percent from EUR 577.00. The move came as the company entered the latest session with first half 2026 revenue growth in the double digits and EBIT expanding faster than sales.

Half year growth lifts margins

According to Ad Hoc News on September 21, 2026, Rational reported double digit revenue growth in the first half of 2026 versus the first half of 2025. EBIT increased at a faster rate than revenue during the same period, raising the operating margin.

The comparison matters because faster EBIT growth creates operating leverage: each additional percentage point of sales growth contributes more to earnings than in the prior-year period. The available report summary also states that Rational expects further revenue growth in fiscal year 2026 and a stable to slightly improved EBIT margin.

Stock remains below yearly high

The September 21, 2026 Xetra close of EUR 578.50 was EUR 42.50 below the 52-week low of EUR 621.00 cited in the same market context and EUR 296.50 below the 52-week high of EUR 875.00. That range shows that the share price remains materially below the upper end of its latest annual trading band.

A separate market update dated September 19, 2026 placed Rational at EUR 675.60 on Xetra and valued the company at about EUR 7.7 billion, while quoting a 52-week range of EUR 621.00 to EUR 875.00. The conflicting close values require venue and timestamp discipline; this article uses the September 21, 2026 quote because it is the latest dated session figure in the current market update.
