What: Shares of Integrated Silicon Solution rose as much as 14% on Thursday after the fabless semiconductor company announced it has agreed to be acquired in an all-cash deal for $19.25 per share by a Chinese group of investors led by Summitview Capital.

So what: On Dec. 1, respected activist investor Starboard Value, ISSI's second largest shareholder with an 8% stake, published an open letter to the company's CEO and its Board of Directors. In it, Starboard advised ISSI to focus on its specialty memory products for the auto and industrial markets rather than continue pursuing distracting acquisitions and it proposed a slate of five candidates for election to the Board. ISSI's stock, which closed at $14.42 on the trading day prior to the letter's release, gained 6% on the day.

Now what: In its December letter, Starboard Value wrote:
