Exhibit 99.1

FOR IMMEDIATE RELEASE

COMMUNICATIONS SYSTEMS, INC. REPORTS FIRST QUARTER 2021 FINANCIAL RESULTS

Reporting strong growth and margin improvement

Minnetonka, MN – May 7, 2021 – Communications Systems, Inc. (NASDAQ: JCS) (“CSI” or the “Company”), which has operated as a global IoT intelligent edge products and services company, today announced financial results for the first quarter (“Q1”) ended March 31, 2021, including a discussion of results of operations by segment.

Management Comments for Q1 2021

Anita Kumar, CSI’s CEO commented, “Although our operations in Q1 2021 continued to be affected by the COVID-19 pandemic which resulted in supply chain challenges and delays in project spending by customers, due to the proactive measures we took and the resilience of our team, we were able to take advantage of the growing need for actionable insight and ubiquitous connectivity at the edge of networks. As a result, our total consolidated sales increased by 11% and gross margin improved by 13%.”

“That said, in April 2021, we entered into a definitive securities purchase agreement (“Purchase Agreement”) with Lantronix, Inc. (“Lantronix”), to sell our Electronics and Software segment (E&S Segment), which contains our Transition Networks and Net2Edge businesses, for a base price of $25.0 million to be paid at closing, subject to a working capital adjustment following the closing, plus up to an additional $7.0 million in earnout payments based on revenue milestones for the E&S Segment businesses in the two consecutive 180-day periods after closing of the sale.”

Roger Lacey, CSI’s Chairman noted, “The agreement to sell our E&S Segment businesses marks an important milestone towards our goal of completing the previously announced merger with Pineapple Energy, LLC (“Pineapple”), a growing U.S. operator and consolidator of residential solar, battery storage, and grid services solutions. As previously announced, we plan to distribute available sale proceeds from any pre-merger divestitures, together with other available cash in the form of a cash dividend to existing CSI shareholders prior to the effective date of the Pineapple merger. CSI’s balance sheet at March 31, 2021 included cash, cash equivalents, and liquid investments of $21.0 million and the divestiture of assets to Lantronix for $25.0 million, will further increase our cash position. Currently, we intend to distribute $3.50 per share or approximately $35.0 million, consisting of proceeds from the sale of the E&S Segment businesses and other available cash after closing the sale of these businesses, but prior to the closing of the CSI-Pineapple merger. We will provide more information about the payment of this proposed dividend in the future.”

Electronics & Software

Electronics & Software sales decreased 2% to $8,365,000 in Q1 2021 compared to $8,536,000 in Q1 2020. Sales in North America decreased $247,000, or 3%, primarily due to supply chain constraints in addition to delayed project spending by customers due to the COVID-19 pandemic. International sales increased $76,000, or 7%, primarily due to growth in the Asia Pacific region of sales of our traditional products. Sales of Intelligent edge solutions (“IES”) products increased 11% or $359,000 due to an uptick in our core IES media converter products by Federal agencies and an uptick in our Switch products used in security and surveillance applications. Traditional product sales decreased 10% or $530,000 due to supply chain constraints in addition to delayed project spending by customers due to the COVID-19 pandemic.

Q1 2021 Gross profit decreased to $3,584,000 from $3,729,000 in Q1 2020. Gross margin decreased to 42.8% in Q1 2021 from 43.7% in Q1 2020 primarily due to an unfavorable product mix including some lower margin sales on IES products sold to Federal agencies due to competitive bidding. Selling, general and administrative expenses decreased 7% to $3,608,000, or 43.1% of sales, in Q1 2021 compared to $3,897,000, or 45.7% of sales, in Q1 2020 due to reduced travel, marketing and personnel expenses, in part due to steps taken by management in response to the COVID-19 pandemic.

Electronics & Software incurred an operating loss of $24,000 in Q1 2021 compared to an operating loss of $168,000 in Q1 2020, primarily due to lower sales and gross margin.

Services & Support

Revenues from the education sector decreased $30,000 or 32% in Q1 2021 as compared to Q1 2020 due to the substantial completion of projects from the Company’s Florida school district customer.

Revenue from sales to small and medium size businesses, which are primarily financial, healthcare and commercial clients increased $1,198,000 or 225% in Q1 2021 as compared to Q1 2020 due to the acquisition of Ecessa on May 14, 2020 and the acquisition of the assets of IVDesk on November 3, 2020. Also, project and product revenue increased $244,000 or 173% in Q1 2021 as compared to the same period of 2020 primarily due to the acquisition of Ecessa and its SD-WAN products. Similarly, services and support revenue increased $867,000 or 126% as compared to the same quarter of the prior year due to the Company’s acquisition of Ecessa and its service and support revenue on its SD-WAN products as well as the acquisition of IVDesk, which contributed $597,000 in revenue during the quarter. Overall, Ecessa contributed $653,000 in revenue during the quarter.

Gross margin increased to 40.0% in Q1 2021 compared to 25.0% in Q1 2020 due to the increase in services & support revenue, which has higher margins. Selling, general and administrative expenses increased 198% in Q1 2021 to $979,000, or 50.5% of sales, compared to $328,000, or 39.7% of sales, in the same period of 2020 due to the May 2020 acquisition of Ecessa and the inclusion of its general and administrative costs that are not included in the prior year.

Services & Support incurred an operating loss of $203,000 in Q1 2021 compared to an operating loss of $121,000 in the same period of 2020, primarily due to increased selling, general and administrative expenses, including amortization expense.
