Why did EOS rise 16.2% on 29 May 2026?
Electro Optic
EOS shares surged following the announcement of a major deal with MARSS, a capital raise, and the appointment of former senior defence leaders to its board.
Multiple news articles around the event date highlight the MARSS deal as a key catalyst, alongside a capital raise and new board appointments. The price surge aligns with these company-specific announcements rather than sector or macro factors. However, the exact timing and relative impact of each piece of news is not fully clear, so confidence is medium.
