FOR IMMEDIATE RELEASE

COMMUNICATIONS SYSTEMS, INC. REPORTS 2020 FOURTH QUARTER AND YEAR-END FINANCIAL RESULTS

Company Also Updates Shareholders on Progress Towards Completing its Previously Announced Merger with Pineapple Energy

Minnetonka, MN – March 30, 2021 – Communications Systems, Inc. (NASDAQ: JCS) (“CSI” or the “Company”), an IoT intelligent edge products and services company, today announced financial results for the fourth quarter and full year (“FY”) ended December 31, 2020.

Q4 2020 Financial Highlights vs Q4 2019

FY 2020 Financial Highlights vs FY 2019

Anita Kumar, CEO of CSI commented, “Our full year 2020 financial results were negatively affected by the COVID-19 pandemic. Our commercial customers, both in the U.S and internationally, were substantially affected by reduced growth in building lighting and automation, security and surveillance and intelligent transportation applications, which resulted in delays and declines in project spending. This decline was partially offset by strong demand from the U.S. Federal government. While the duration and the global economic effect of this pandemic is outside of our control, during the year we took several steps to adjust to this challenging new operating and economic environment. We implemented cost-reduction measures, which partially offset lower revenue and resulted in positive operating income and net income for the second half of 2020.”

Dr. Kumar added, “Both our business segments remain fundamentally strong due to the investments we made in new technologies. These investments are aimed at developing easy-to-use / easy-to-integrate software and services that address demand from critical infrastructure initiatives, including security and surveillance, intelligent transportation, smart buildings, and smart cities. With the acquisition of Ecessa, a designer and distributor of SD-WAN for businesses, we expanded our services and support segment broadening our portfolio of products and services. Also, the minority investments we have made in Quortus, Kogniz and Spyrus expanded our ability to explore providing Private LTE, Artificial Intelligence and secure network access solutions to our customers.”

Progress Made Towards Completing its Previously Announced Merger with Pineapple Energy

Of note, on March 2, 2021, CSI announced the signing of a definitive merger agreement with privately held Pineapple Energy, LLC (“Pineapple”), a growing U.S. operator and consolidator of residential solar, battery storage, and grid services solutions. Upon obtaining shareholder approval for the merger and closing, CSI will commence doing business as Pineapple Energy, with a business model focused on the rapidly growing home solar industry.

Commenting on the progress made towards completing the merger with Pineapple, Roger Lacey, Executive Chairman of CSI, commented, “As per the terms of the merger, we intend to divest all of our existing business lines, real estate holdings and other investments, and distribute the proceeds to CSI Shareholders. Currently, we are in discussions with potential buyers for both our operating business segments (Electronics & Software and Services & Support). These businesses could offer potential buyers substantial long-term growth opportunities by unlocking additional synergies, and the ability to expand into adjacent markets, add scale, and broaden their existing product lines. We will provide additional details once we enter into definitive agreements.”

As previously announced, we expect to distribute most of the proceeds from any pre-merger divestitures in the form of a cash dividend to existing CSI shareholders prior to, or concurrent with the effective date of the merger.

The definitive merger agreement with Pineapple, which was approved by CSI’s Board of Directors, is subject to approval by CSI’s shareholders, which we currently expect to occur in June 2021, with the merger expected to close before the end of the second quarter of 2021.

FY 2020 Segment Financial Overview

Electronics & Software

Electronics & Software Q4 2020 sales and operating income decreases were driven by the $4.2 million 2019 New York City Department of Transportation (“NYCDOT”) project related revenue which did not reoccur in 2020, and the impact of project delays driven by the COVID-19 pandemic.

Electronics & Software sales decreased 27% to $34,496,000 in FY 2020 compared to $47,007,000 in FY 2019. Sales in North America decreased by 25% or $10,050,000 in FY 2020 compared to 2019 primarily due to delayed project spending by customers due to the effect of the COVID-19 pandemic, $7,050,000 of sales on the NYCDOT IoT project recorded in FY 2019 that did not reoccur in FY 2020, and a decline in sales to a major Canadian telecommunications customer, partially offset by strong sales to Federal agencies. International sales decreased by $2,461,000, or 34%, primarily due to the economic effects of the COVID-19 pandemic and an overall drop in demand for traditional products.

Sales of Intelligent Edge Solutions (“IES”) products decreased 34% or $6,280,000 due to the $7,050,000 of deliveries in FY 2019 for the NYCDOT project that did not reoccur in FY 2020, partially offset by higher sales of security and surveillance products and sales to Federal agencies. Excluding the prior year NYCDOT IoT project, sales of IES products increased by $770,000 or 7%. Traditional product sales decreased 22% or $6,231,000, due mainly to the overall economic effects of the COVID-19 pandemic and a decline in media converter orders from major telecommunications customers.

Gross profit decreased by 30% to $14,890,000 in FY 2020 compared to $21,394,000 in FY 2019. Gross margin as a percentage of sales decreased to 43% in 2020 from 46% in 2019 primarily due to the volume and favorable margin impacts from the prior year NYCDOT smart city IoT project that did not reoccur in the current year and increased sales of certain IES products to Federal agencies at lower margins, partially offset by lower inventory write-downs year over year.

Selling, general and administrative expenses decreased by 20% to $13,875,000, or 40% of sales, in FY 2020 from $17,354,000, or 37% of sales in FY 2019 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 had operating income of $1,015,000 in FY 2020 compared to operating income of $4,040,000 in FY 2019, primarily due to lower sales and gross margin.

Services & Support

Services & Support sales increase in Q4 2020 was driven by education sector projects restarted in 2020 and the addition of revenues from Ecessa and IVDesk, which were both acquired in 2020.

Services & Support sales increased by 85% to $8,777,000 in FY 2020 compared to $4,741,000 in FY 2019. Revenues from the education sector increased by $2,557,000 or 133% in FY 2020 primarily due to the commencement of projects that had been previously delayed due to funding issues while the prior year had less project revenue in this sector. Projects for this education customer commenced at the end of the second quarter of FY 2020. Revenue from small to medium businesses (“SMBs”), which are primarily healthcare, financial and commercial clients, increased by 82% or $1,622,000 due to the acquisition of Ecessa on May 14, 2020 and the acquisition of the assets of IVDesk on November 3, 2020. Project and product revenue increased by $2,878,000 or 128% during FY 2020 as compared to FY 2019 due primarily to the increase in the education sector. Services and support revenue increased by $1,158,000 or 46% as compared to the prior year due to the Company’s acquisition of Ecessa, which has service and support revenue on its SD-WAN products. Overall, Ecessa contributed $1,260,000 and IVDesk contributed $401,000 in revenue during the year.

Gross profit increased by 101% to $2,979,000 in FY 2020 compared to $1,482,000 in FY 2019. Gross margin as a percentage of sales increased to 34% in 2020 compared to 31% in 2019 due to the increase in project revenue in the education sector, primarily within the second half of the year.

Selling, general and administrative expenses increased by 80% in FY 2020 to $2,669,000, or 30% of sales, compared to $1,485,000 in FY 2019, or 31% of sales 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.

Operating income was $310,000 in FY 2020 compared to an operating loss of $3,000 in FY 2019, primarily due to increased education revenue.
