Mellanox Technologies Ltd.  (MLNX) , a global computer networking products supplier headquartered in Israel, reportedly is a takeover candidate. 

The stock rose as much as 15% on Friday, Oct. 26, sending the stock's market cap to more than $4.4 billion. Mellanox, CNBC reported, has garnered interest from at least two buyers. Mellanox has hired a financial adviser to explore a sale. 

The push for a sale comes from activist value investment firm Starboard Value LP, which has more than $4 billion under management. Starboard had successfully pushed for three new board directors early this year. It currently holds an 8.6% stake in Mellanox. 

Mellanox makes chips and other hardware products for data centers. The current valuation, clearly reflecting an expected premium on a potential sale, brings the company's trailing 12 months earnings multiple to about 81.
