In December 2013, Crittenden oversaw the acquisition of Lucent Polymers by the HGGC company Citadel Plastics Holdings, a top global thermoplastics and thermoset resins compounder. The acquisition gave Citadel Plastics access to a portfolio of over 1,400 formulations and enhanced its position in the engineered resins sector. Crittenden heralded the acquisition as a prime example of growth via strategic acquisition and integration of successful, complementary businesses. According to Crittenden, Citadel Plastics will benefit greatly from the financial strength and blue-chip customer base of Lucent, as well as its numerous development initiatives. The Lucent acquisition was Citadel's seventh since 2007 and the 31st overall acquisition for HGGC.
