Ribbon Communications sees Q1 revenue $180M-$190M, consensus $185.7M

Q1 revenue guidance represents an increase of 7% year-over-year at the mid-point, constrained by a small number of specific supply chain shortages. Non-GAAP gross margin is projected in a range of 46%-48%, lower than typical as a result of higher start-up costs associated with several new customer wins and product mix. Adjusted EBITDA is projected in a range of ($6M)-$1M.
