CompoSecure (CMPO) shares plummeted nearly 7% in Wednesday's after-market session, following the payment card maker's weaker-than-expected fourth quarter earnings results.

For the quarter ended December 31, 2024, CMPO reported net sales of $100.9 million, up just 1% year-over-year and missing the consensus estimate of $102.2 million. The company cited higher costs and expenses related to new card designs, production inefficiencies, and inflationary pressures weighing on profitability.
