George Soros' family office Soros Fund Management has filed a 13G with the SEC regarding their stake in Mercury Systems (MRCY).  Per the filing, Soros has revealed a 5.02% ownership stake in MRCY with 1,666,666 shares.

This means their equity stake has increased to the tune of 400,000 shares since the end of the second quarter, or around a 32% boost from their last disclosure.  The latest filing was required due to portfolio activity on October 22nd. 

This has been a longstanding position for Soros as we covered their stake back in 2009, when they owned equity and also convertible notes.
