Stocks to watch: Jason Holdings, Yeo Hiap Seng, Olam International

THE following listed companies made material announcements before the Singapore market opened on Thursday.

Jason Holdings: Troubled timber flooring specialist Jason Holdings, which is dealing with corporate governance and debt repayment issues, has released its unaudited full-year and adjusted half-year results for 2015. The firm registered a S$13.8 million net loss for the full year compared with a S$215,000 net profit in its restated 2014 results.

Yeo Hiap Seng: Shares of Yeo Hiap Seng jumped more than 13 per cent on Wednesday from the previous day's close, prompting a query from the Singapore bourse operator. This comes two days after a research report stated that there were no plans to delist the food and beverage company and that it had yet to realise its full potential.

Olam International: Agri-business group Olam International said on Wednesday that it has acquired the remaining 50 per cent stake that it does not already own in Acacia Investments from its joint venture partner for US$24 million. The acquisition is expected to be completed this month.
