Adtran Networks stock closed at EUR 22.40 on Xetra on September 18, 2026, gaining 0.45 percent from the prior session. The move contrasted with the DAX, which fell 1.60 percent to 25,304.06 points on the same date.

September 18, 2026 in numbers

Adtran Networks AG (ISIN DE000A14U784) ended the last completed Xetra session at EUR 22.40. The dated market report also identified the September 18, 2026 close as the central reference for the shares, while a later portal snapshot showed EUR 22.80 without representing the completed Xetra close.

The stock therefore outperformed the DAX by 2.05 percentage points in the September 18, 2026 session. A market report published on September 21, 2026 described the stock as holding its level after the modest Xetra increase, but supplied no company-specific catalyst for the move.

September 22, 2026 trading outlook
