Exhibit 99.4

Business Partners Communication

Upon announcement of the proposed acquisition of Bsquare Corporation (“Bsquare”) by Kontron America, Incorporated (“Kontron”), Bsquare and Kontron are providing the following information to customers:

● Kontron and Bsquare have executed a merger agreement whereby Kontron will commence a tender offer for the outstanding shares of Bsquare. Under the agreement, a successful tender will be followed by a merger to acquire any untendered shares and Bsquare will merge into Kontron’s US subsidiary, Kontron Merger Sub., Inc., based in San Diego, CA.

● The tender offer and the merger are subject to certain customary and other closing conditions.

● While the tender and merger are in progress nothing will change for Bsquare customers. Microsoft licensing customers should expect to continue purchasing as they have in the past and we will continue to provide industry-leading technical support and business services. We will continue to provide operations and software development services for our Edge-to-Cloud and SquareOne customers.

● We believe that Bsquare’s software products and services will combine naturally with Kontron’s IoT hardware products and services to create a more complete solution for our customers.
