QualTek Services Inc. became a public company through its business combination with Roth CH Acquisition II Co., a blank-check company that traded under the ticker ROCR and completed its IPO in 2021, sponsored jointly by Roth Capital Partners and Craig-Hallum Capital Group. QualTek operates in the telecommunications and renewable energy infrastructure services sector, providing network, utility, and wireless services to major carriers and utilities across North America. The de-SPAC transaction closed in February 2022, but the combined company filed for Chapter 11 bankruptcy protection in early 2023. This 8-K, filed May 31, 2023, reflects a subsequent development in QualTek's ongoing restructuring proceedings.
