Financial Summary

Revenue in the first quarter of 2021 totaled $13.3 million as compared to the record Q1 of $13.4 million in the same year-ago quarter. Although the higher margin OSS core business improved, it was offset by a modest decrease in Bressner revenue.

Gross profit was $4.4 million or 33.3% of revenue, up from $3.4 million or 25.4% of revenue in Q1 2020. The significant improvement in quarterly margin was attributed to a higher mix of government business of $2 million, with this revenue primarily generated by three of the company’s 2020 design wins, including Datacenter in the Sky, Data Storage Units and 4U Pro.
