Fourth quarter 2022 antennas and industrial IoT device revenue was $16.4 million, a decrease of 14.2% year-over-year, partially due to high customer inventory levels. Fourth quarter 2022 Test & Measurement revenue was $9.9 million, an increase of 37.7% year-over-year due to higher revenues for 5G products in the U.S. Fiscal 2022 revenues were $99.4 million, an increase of 13.2% compared to $87.8 million in fiscal 2021. The increase in revenue for fiscal 2022 was driven by double-digit growth in both segments. Fiscal 2022 Antennas and IIoT Devices revenue was $69.7 million, an increase of 10.5% year-over-year. Fiscal 2022 Test & Measurement revenue was $30.6 million, an increase of 18.9% year-over-year.

Fourth quarter 2022 GAAP gross profit margin was 50.3%, compared to 45.9% in the fourth quarter of 2021. The higher gross profit margin was due to a higher mix of Test & Measurement products. Fiscal 2022 gross profit margin was 46.0%, compared to 46.1% in fiscal 2021.

Adjusted EBITDA in the fourth quarter increased to $3.7 million compared to $3.1 million in the fourth quarter of 2021. Adjusted EBITDA in fiscal 2022 increased to $10.7 million compared to $8.5 million in fiscal 2021.

A reversal of allowances related to deferred income taxes contributed $0.02 per share during the fourth quarter 2022. Non-GAAP net income was $3.0 million, or $0.16 diluted earnings per share, compared to $2.1 million or $0.12 per share in the fourth quarter of 2021.

Fiscal 2022 GAAP net income was $2.9 million or diluted earnings per share of $0.15 compared to GAAP net income of $0.2 million or $0.01 per share during fiscal 2021.

Our leading wireless technology solutions enable us to serve customers in the utilities, rail, 5G and public safety sectors, supporting critical applications that require reliable connectivity. For the first quarter of 2023, we anticipate lower sequential revenue due to typical seasonality effects; however, we maintain a positive outlook for the remainder of the year.
