ONYX HOLDINGS LLC has been licensed as an independent testing lab in Maryland, according to state license records. The entity holds an active Ancillary Business Registration and Independent Testing Lab license (L-25-00001) as of October 10. This marks Maryland's fourth operational testing lab, joining Green Analytics, Pinnacle ct, inc, and Quales, llc, all licensed the same date.

The licensing cluster arrives as Maryland's adult-use market stabilizes. September 2026 sales reached $101.5 million, down slightly from August's $105.2 million but consistent with recent monthly ranges around $100–109 million. The state operates 128 retail outlets, 27 cultivators, and 31 manufacturers, suggesting testing infrastructure expansion may reflect growing production and compliance volume.

Watch whether the addition of multiple labs in a single licensing round signals Maryland's regulator responding to testing bottlenecks, or simply routine licensing processing. Lab capacity typically constrains market velocity in mature adult-use states.
