For 2023, the Company expects to build on the momentum from the second half of 2022, with a stronger portfolio and market presence, and to follow a normal seasonal pattern with the business accelerating as the year progresses.

For the first quarter of 2023, the Company projects revenue of $180 million to $190 million, up 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% to 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 ($6) million to $1 million.

For the full year 2023, the Company projects revenue of $840 million to $870 million, up 4% year-over-year at the mid-point, non-GAAP gross margin of 53% to 54%, and Adjusted EBITDA of $95 million to $110 million, up 60% year-over-year at the mid-point.
