Double gang box. One switched, three hot. Is a shared neutral OK?
Sounds like you've got it.


Neutral feeder comes into the box, and pigtails out to each receptacle (silver colored screw) and a neutral to the switch (if required by 2014 code).
Hot feeder comes into the box, and pigtails to each receptacle (brass colored screw) and a hot to the switch.
Switched hot comes into the box, and connects to one of the receptacle terminals. 
The bonding jumper on the receptacle with two hot feeds is broken.
All grounding conductors are properly connected.
