OHB is trading 4.05% lower at €180.00 on September 29; no clear company-specific announcement dated September 28 or 29 was found to explain the drop. - The latest company-related news was a September 24 memorandum between OHB Sweden and Saab to explore cooperation on space-based defence capabilities. It predates the move and does not establish a cause. - The broader backdrop included renewed geopolitical concerns after the U.S. rejected Iran’s proposal, alongside rising oil prices and Treasury yields. Available evidence does not directly link these factors to OHB’s decline, leaving the specific catalyst unclear.
