Shipments Commencing in Q3 2022 Diversify Revenue Opportunities

Austin, Texas--(Newsfile Corp. - September 6, 2022) - Sonim Technologies (NASDAQ: SONM) today announced a customer purchase order for $9 million to purchase tablet products designed by Sonim and assembled via an ODM relationship. Sonim expects to ship the initial purchase order starting from the third quarter, then fulfill additional orders in late 2022 and throughout 2023. The new tablet order exemplifies Sonim's strategic plans to enter the larger and more diverse industrial equipment market with new devices leveraging its engineering expertise and rugged heritage.

The new tablet features an eight-inch display with 4G LTE connectivity running on a Qualcomm Snapdragon chipset. The tablet targets both enterprise and consumer applications, including service and education applications.

The tablet is an ODM project for which Sonim will design and build the devices for shipment to U.S. carrier partners. The new tablet project is not expected to represent inventory risk Sonim, as the tablets are built to customer purchase orders.

"This tablet project is a good example of our ability to grow revenue in large but untapped end markets where we can apply our engineering expertise to design and deliver purpose built mobile devices to our carrier partners," said Sonim CEO, Peter Liu. "We look forward to bringing additional products to market in this same manner as a means to grow and diversify Sonim's revenue opportunities while at the same time building economies of scale and leveraging our rugged heritage to address unmet needs in the marketplace."
