(NYSE American: WTT) (the “Company”) announced today results for the three months ended March 31, 2022. Tim Whelan, CEO of Wireless Telecom Group, Inc. stated, “Our first quarter revenues reflect a solid delivery against our year-end backlog of $6.7 million. We initially expected nearly $1 million of additional Q1 shipments which are currently being delayed into the second quarter because of supply chain delays and longer than expected export license issuances. We are seeing some modest improvements in supplier delivery dates heading into the second quarter, and we are building our inventory levels to ensure we continue to keep pace with continued customer demand and strong bookings. We expect to see meaningful sequential increases in revenue and bookings in our second quarter.” The Company’s strategic alternatives process remains active and continuing. Second Quarter 2023 Operating Results: Consolidated net revenues decreased $884,000 from the prior year period due to supply chain delays and export license delays. Gross profit margin decreased from 57.9% in the prior year period to 57.0% in the first quarter 2023 due to lower revenue resulting in lower absorption of fixed manufacturing costs. Operating expenses increased $44,000 from the prior year period reflecting higher legal fees and severance expenses offset by lower commissions and stock based compensation expense. Loss from continuing operations of ($941,000) compared to a loss of ($796,000) in the prior year. The higher loss is due primarily to lower gross profit offset by interest income versus interest expense in the prior year. Non-GAAP Adjusted EBITDA of $(123,000) compared to $455,000 in the prior year, primarily due to lower revenues and higher legal expenses. Non-GAAP adjusted EBITDA is a metric the Company uses to measure our core operations.
