Exhibit 99.1

FOR IMMEDIATE RELEASE 

COMMUNICATIONS SYSTEMS, INC. REPORTS THIRD QUARTER 2015 FINANCIAL RESULTS 

Minnetonka, MN – November 4, 2015 – Communications Systems, Inc. (NASDAQ: JCS) (“CSI” or the “Company”), a global provider of physical connectivity infrastructure and services for deployments of broadband networks, today announced financial results for the third quarter (“Q3”) and nine months ended September 30, 2015, including a discussion of results of operations by segment.

Third Quarter 2015 Summary

·      Consolidated operating income was $0.4 million compared to $2.7 million in Q3 2014.

CSI’s Chief Executive Officer Roger H.D. Lacey commented, “Q3 2015 marked our second consecutive quarter of sequential improvement in sales and profitability at each of our businesses. Our Q3 2015 operating profit reflects strengthening 2015 business activity as well as our ongoing efforts to increase new product sales, achieve lean operations, and invest in R&D. While we still have work do, we believe that Suttle, Transition Networks and JDL Technologies are well positioned for long-term growth and profitability.”

He continued, “Suttle’s Q3 2015 performance reflected the ongoing impact of reduced sales and lower margins on passive legacy products associated with a large tier-1 communications service provider. Increased sales to other customers, including expanded international business, reduced our dependency on this major carrier. We continue to focus on developing new products to advance our fiber and active capabilities to ensure that Suttle remains well positioned to benefit from our customers’ continuing deployment of high-speed networks.

“Transition Networks’ Q3 2015 sales increased by 10%, driven by a rebound in federal spending and growth in North America. Transition Networks improved its profitability this quarter through good expense management and a one-time research and development tax refund of approximately $0.3 million from amended 2011 and 2012 state tax returns. This improved profitability was notwithstanding our continued investment in the development of new products. We continue to add features to our media conversion products that are designed to overcome bandwidth, security and distance limitations.”

Mr. Lacey concluded, “JDL Technologies’ Q3 2015 sales increased by 124%, driven by work associated with the School Board of Broward County as well as new managed services business. JDL experienced favorable operating leverage this quarter as Broward revenues increased, translating into operating income of nearly $1 million compared to a loss in Q3 2014. With the reinstatement of E-Rate funding in Q3 2015, we expect Broward sales to remain robust through 2016 and beyond. Outside of its core educational vertical, JDL continues to grow its managed services recurring revenue stream, led by its HIPAA-compliant IT services offerings, while penetrating new markets, such as Minneapolis and Atlanta.”

Segment Financial Overview

See the Communications Systems, Inc. Form 10-Q to be filed on or about November 6, 2015 for more details of the quarter.

CSI operates through the following business units:

Suttle

Suttle’s Q3 2015 sales decreased 24% to $15.1 million, from $19.9 million in Q3 2014, primarily due to increased pricing pressure and volume declines in its legacy product lines.

Sales to the major communication service providers declined 37% to $11.0 million in Q3 2015, from $17.4 million in Q3 2014, and comprised 73% of total segment revenues. Lower sales to communications service providers reflected a decline in legacy product purchases, including a reduction of purchases by a major customer starting in Q1 2015 and continuing through Q3 2015. FTTx product sales as a group declined 39% to $3.6 million in Q3 2015 from $5.8 million in Q3 2014, also reflecting the purchase curtailment by this same major customer that purchased a significant amount of FTTx products in Q3 2014. Apart from the impact of this customer’s curtailment, Suttle continued to achieve underlying growth in core high-speed copper connectivity products and secured new business in multiple FTTx domains during the quarter.

In other product categories, sales of structured cabling decreased 44% from $9.0 million in Q3 2014 to $5.1 million in Q3 2015 due to reduced demand by major customers. Reflecting continuing shifts in technology, sales of modular connecting products decreased 15% from $3.6 million in Q3 2014 to $3.0 million in Q3 2015. Sales of DSL products increased 138% from $1.4 million in Q3 2014 to $3.4 million in Q3 2015, due to increased ordering from a major international customer.

International sales increased 283% to $3.3 million in Q3 2015 due to the ordering cycle of DSL products and introduction of new products used in FTTx deployments for a major customer, and comprised 22% of total segment revenues. Sales to distributors decreased 52% to $0.8 million in Q3 2015 due to a continuing decline in legacy product lines, and comprised 5% of total segment revenues.

Gross profit in Q3 2015 declined 52% to $3.1 million, or 20.5% of sales, from $6.5 million, or 32.4% of sales, in Q3 2014. Gross profit as a percentage of sales decreased due to a series of factors, including pricing pressure from a major customer, a relatively high production cost variance due to decreased demand, and higher allocation of overhead to cost of goods sold resulting from recent investment into production capabilities to support new FTTx product platforms.

Suttle’s operating loss totaled $0.8 million in Q3 2015 compared to operating income of $2.8 million in Q3 2014, reflecting lower gross profit and a $0.2 million increase in selling, general and administrative (“SG&A”) expense. Research and development expenses were $1.7 million in Q3 2015 and $1.0 million in Q3 2014, as Suttle continues to invest in enhancing existing products and developing new products.

Transition Networks

Transition Networks’ Q3 2015 sales increased 10% to $12.4 million from $11.3 million in Q3 2014, reflecting a 14% increase in North America sales, partially offset by a 2% decline in international sales. By product category, a 102% increase in Ethernet adapter sales, 18% rise in other product sales and 9% increase in Ethernet switch sales more than offset an 8% decline in media converter sales. Media converter sales represented 56% of total segment sales in Q3 2015, down from 66% of total segment sales in Q3 2014.

Gross profit increased 15% to $5.7 million, or 46.4% of segment sales, compared to $5.0 million, or 44.3% of segment sales, in Q3 2014, due to favorable product mix.

Transition Networks’ operating income was $0.3 million, and included $293,000 from refundable research and development tax credits for the amended 2011 and 2012 state tax returns, compared to an operating loss of $43,000 in Q3 2014.

JDL Technologies

JDL Technologies’ Q3 2015 sales increased 124% to $5.0 million from $2.2 million in Q3 2014, primarily reflecting a $2.1 million increase in revenues earned from the School Board of Broward County.

This was the result of the District proceeding with its Data Center Upgrade initiative as well as several wireless upgrades funded through grants outside of E-Rate. The Schools and Library Department of the federal government has provided confirmation of E-Rate awards in Q3 2015. Initiatives utilizing these contracts began in Q3 2015 and are expected to continue for several years.

Sales to small- and medium-sized commercial businesses (SMBs) increased $0.6 million, or 160%, due to the acquisition of several new clients and the June 2015 acquisition of Twisted Technologies.  In September 2015, JDL Technologies’ managed services business achieved an annual recurring revenue run rate of approximately $2.5 million, primarily driven by strong demand for its HIPAA-Compliant IT services and expansion into the financial and legal verticals. While the composition of these contracts may vary, the Company believes the achievement of this milestone reflects the potential of and the increasing demand for the services of the JDL Technologies segment.

Q3 2015 gross profit increased 219% to $1.8 million, or 35.6% of segment sales, from $0.6 million, or 25.0% of sales, in Q3 2014.

JDL Technologies’ operating income was $0.9 million, compared to an operating loss of $0.1 million in Q3 2014.
