Executive Summary

Q4 2022 revenue was $41.7M, essentially flat quarter-over-quarter (-0.7% vs Q3) and down 17% year-over-year, while gross margin expanded sharply to 46.1% from 39.8% in Q3 on improved mix; diluted EPS improved to -$0.15 vs -$0.32 in Q3; Adjusted EBITDA loss narrowed to -$5.0M from -$10.0M in Q3 .
Operating expenses fell to $27.0M (from $33.1M in Q3) as cost-reduction actions flowed through, driving quarter-over-quarter profitability improvements despite supply-chain cost pressures earlier in the year .
Liquidity and covenant risk intensified: cash fell to $7.3M at year-end; the company disclosed covenant breaches and substantial doubt about going concern absent waivers/financing, making debt resolution a critical near-term catalyst .
Strategic focus sharpened post-quarter with agreement to sell Mimosa Networks for ~$60M cash (CFIUS/Turkish approvals pending), aligning resources around 4G/5G Open RAN and private networks; deal close and proceeds deployment are key stock catalysts .

What Went Well and What Went Wrong

What Went Well
- Gross margin expanded to 46.1% in Q4 (from 39.8% in Q3), reflecting favorable product mix and cost actions; management highlighted “higher gross margins due to product mix and lower operating expenses recorded as a result of the reductions in headcount” .
- Adjusted EBITDA improved throughout 2022, reaching -$5.0M in Q4 vs -$18.0M in Q1, driven by margin gains and opex reduction .
- Operating expenses declined to $27.0M in Q4 from $33.1M in Q3, reflecting restructuring and cost discipline .
What Went Wrong
- Revenue pressure persisted: Q4 revenue was $41.7M, down ~17% year-over-year, and Q2–Q3 showed service revenue headwinds as NRE and maintenance contracts rolled off .
- Liquidity deteriorated; cash and equivalents fell to $7.3M at year-end; management disclosed covenant breaches and going concern risks without waivers or new capital .
- Supply chain and component costs weighed on gross cost structure across Q2–Q3 before mix-driven margin recovery in Q4 .

Management Commentary

“Adjusted EBITDA improved from a loss of $18.0 million in Q122 to a loss of $5.0 million in Q422 as a result of higher gross margins due to product mix and lower operating expenses recorded as a result of the reductions in headcount.” (Exhibit 99.1 press release) .
Risk disclosure: “There is substantial doubt about our ability to continue as a going concern… absent waivers or remedies of existing covenant breaches or additional financing.” (10-K) .

Key Takeaways for Investors

Margin recovery is notable: Q4 gross margin reached 46.1%, driving sequential improvements in EPS and Adjusted EBITDA despite revenue pressure .
Cost discipline is working: Q4 OpEx dropped to $27.0M (from $33.1M in Q3), underpinning profitability trajectory improvements into 2023 if sustained .
Liquidity/covenant resolution is the near-term gating factor: year-end cash was $7.3M and covenant breaches/going concern disclosures make waivers, refinancing, or proceeds from Mimosa pivotal catalysts .
Mimosa sale (~$60M cash) and related agreements (reseller/TSA/license) can stabilize liquidity and sharpen strategic focus; watch for regulatory clearances and closing timeline .
Customer concentration remains high historically (50–70% of revenue from top three customers); execution on diversification and private/Open RAN wins is key to medium-term resilience .
Supply-chain costs pressured earlier quarters; Q4 mix aided margins—sustainability of margin gains depends on continued product mix benefits and easing component costs .
