This looks like a case of holly leaf spot, which is common, and affects vigorusly growing plants, or plants that are soft in growth and sheltered, causing leaves to drop off.

The plants are likely to sprout again but may be affected again. Spraying is of limited effect but might help if you try a copper spray such as Bordeau mixture.
