Could be a number of things or a combination of problems. But it is for sure "Further evaluation by a certified stucco / EIFS inspector". IR would be helpful and could determine extent of moisture behind stucco / in wall, but it will still need to be confirmed with probe moisture meter.
Cracks indicate stucco too thin. (should be 7/8 inch) and / or insufficient drying time between coats.
Stains could be moisture behind stucco rusting the wire lath and bleeding out or OSB tea. (Vertical mulch getting wet causing stains)
Either way moisture should not be behind stucco.
Great forum, great information.
