On January 28, 2016, Acorn announced the sale of a 50% strategic interest in its DSIT Solutions, Ltd. business to Rafael Advanced Defense Systems, a major Israeli defense company. Acorn expects to receive gross proceeds of approximately $4.9 million before escrow (approximately $0.6 million), fees and taxes. Acorn is also eligible to receive its pro-rata share of a $1.0 million earn-out over a three-year period. In addition to customary closing conditions, the DSIT Transaction requires the approval of the Israeli Ministry of Defense and the Israeli Anti-Trust Authority. Both approvals have already been received. Acorn expects that the DSIT Transaction will close in the first two weeks of April 2016. Following the sale, Acorn will own approximately 41.2% of DSIT.

Portfolio Companies

DSIT Solutions Ltd., based in Israel, develops and produces advanced underwater sonar detection systems to protect ships and critical harbor installations against attack. Primary customers for its systems are navies, homeland security agencies, oil and gas (O&G) companies, nuclear power facilities and port authorities.

DSIT's fiscal year 2015 revenue was $13.5 million vs. $12.3 million in 2014. The increase in revenue was primarily due to a $15.4 million order received in early 2015 for four Hull Mounted Sonar (HMS) systems and an anti-Submarine Warfare (ASW) trainer for an undisclosed navy. DSIT's backlog at the end of 2015 was $20.6 million as compared to $12.0 million at the end of 2014.

GridSense develops and markets remote monitoring systems for electric utility companies. The systems are used for outage management, power quality measurement, systems planning, trouble-shooting and maintenance. The company's focus is on the early detection of problems on power lines and transformers and the prevention of power outages. Its unique solution is applicable to hundreds of thousands of underground and vault transformers, most of which are approaching or past their life expectancies. Compared to manual inspections, the use of remote monitoring can save time and money and alert management to problems and possible failures. Also closer monitoring and maintenance can help extend the usable lives of transformers, whose replacement costs are prohibitive. GridSense's low-cost and effective monitoring system is one answer to a growing problem.

Fiscal year 2015 revenue was $2.5 million compared to $4.5 million in 2014. The decrease in revenues was due to lower backlog entering 2015 combined with a reduced sales force in place in the U.S. in the beginning of 2015. R&D expenses were $0.5 million compared to $1.1 million in 2014 (a reduction of 54%) while SG&A expenses for 2015 decreased $0.9 million, or 32% compared to 2014. The decrease in expenses were primarily due to the elimination of GridSense's Australian operations and the downsizing of its U.S. operations following GridSense's restructuring which began in mid-2013.

GridSense's management has realigned its sales and engineering efforts and is focusing on more standardized opportunities which seem most likely to result in commercial-scale orders. Specifically, GridSense plans to focus sales efforts in 2016 only on those products that have already shown the most traction in the marketplace such as the Transformer IQ® and the Line IQ®.

OmniMetrix has developed what it believes are the most advanced systems available for wirelessly and remotely monitoring back-up generators and other equipment, like oil corrosion protection systems on pipelines, to prevent failures. The system collects key data continuously and alerts the responsible manager to signs of trouble. With the emergence of applications that aggregate multiple sensors and monitors into a simplified customer dashboard interface, OmniMetrix, which monitors all major brands of critical equipment, believes it can play a key role in this new market.

OmniMetrix is marketing its products to end-users as well as to select dealers identified as possessing both a substantial maintenance customer base and a willingness to provide value-added services. OmniMetrix also provides corrosion monitoring and control of gas pipelines.

OmniMetrix revenue increased 11% from $2.8 million in 2014 to $3.0 million in 2015. The increase in revenue was driven by increased monitoring revenue. Gross margins for fiscal year 2015 were 59% compared to 58% in 2014. As monitoring revenue continues to grow, OmniMetrix's margins are expected to increase as well, as monitoring revenues

generate significantly higher margins than hardware sales.

Acorn Energy will host a conference call to discuss fourth quarter and year-end 2015 results and corporate developments shortly after the closing of the sale of a portion of its holdings in DSIT which is expected in April 2016.
