OnTheMarket PLC (AIM:OTMP) flagged that proxy voting adviser ISS has issued a voting recommendation in favour of the CoStar takeover. It noted that ISS has recommended to its clients that shareholders vote for the deal at the 4 December meetings, in line with the board's unanimous recommendation. US giant CoStar made the £99 million bid last month, with the 110p per share offer price a 56% premium to the last close price, though below short-term levels seen in 2019 and 2021.
