Press Release & Investor Call

Acorn’s Q2 EPS of $0.12 Reflects Increasing High-Margin, Recurring Monitoring Revenue; Growth Initiatives Include New Generator Partnership and OMNI360 Launch

Wilmington, DE – August 6, 2026 – Acorn Energy, Inc. (Nasdaq: ACFN), a provider of remote monitoring and control solutions for generators, gas pipelines, cell tower campuses and other critical infrastructure, announced results for its 2026 second quarter (Q2’26) and six months (6M’26) ended June 30, 2026. Acorn will hold an investor call today at 11am ET (details below).

(1) All of Acorn’s revenue is derived from its 99%-owned operating subsidiary, OmniMetrix™, LLC.

CEO Commentary

Jan Loeb, Acorn’s CEO, said, “Q2 results showed continued strength in high-margin, recurring monitoring revenue from a growing base of monitored endpoints, offset by lower hardware revenue, primarily due to the timing of deployments for a national cell phone provider initiated in late 2024. Hardware revenue from the customer was $263,000 in Q2’26, compared to $1,338,000 in Q2’25.

“Supporting our long-term growth prospects in the residential market is a new partnership agreement with Champion Power Equipment which makes OmniMetrix remote monitoring and control the standard monitoring option on Champion’s aXis and fleX home standby generators. Champion is one of the fastest-growing generator brands in the industry, with a strong position in the residential market. It’s a significant opportunity for us that should begin to positively impact our results in the current quarter.

“Earlier this year, we secured North American rights to a comprehensive suite of remote monitoring solutions with AI-driven insights for telecommunication towers, energy sites, and data centers and formed an Infrastructure Solutions reporting segment for this business. Following several months of development, customization and product enhancements, we formally launched the segment’s first product – OMNI360, which delivers remote monitoring and control solutions for a wide range of critical functions at cell tower campuses.

“OMNI360 is an all-in-one site level management system offered in three different tiers of varying scope with 24/7 network operations center (NOC) support. Capabilities include monitoring/management of environmental changes (temperature, humidity, HVAC control, smoke detection, flood sensors); campus security (AI cameras, site access and intrusion sensing, two-way audio and live incident response); power monitoring and management solutions (fuel sensing and usage prediction, commercial power automatic transfer switch, battery health, transformer temperature, voltage/current imbalance detection); plus smart energy and cooling optimization.

“We are very excited about OMNI360’s potential and are actively working to introduce the product suite across the telecom industry. Given the breadth of the solution, its expanded capabilities and the large size of prospective customers, we anticipate a longer sales cycle but hope to be surprised. Accordingly, it’s too early to provide visibility on the timing of potential revenue opportunities for the OMNI360 suite.

“We also remain active in pursuing complementary strategic M&A opportunities that are accretive to revenue and earnings, where the challenge has been finding the right opportunity on terms that can create value for shareholders. With the significant hardware revenue contributions from our large national cell phone provider now cycled through our year-ago comparison periods, we expect more favorable revenue comparisons moving forward. These factors combined with our growth initiatives should enable us to bring our top-line growth more in line with our three- to five-year target of 20% average annual growth in coming quarters.”

Financial Review

Q2’26 revenue decreased 29.4% to $2,489,000 versus $3,525,000 in Q2’25, primarily due to a $1,141,000 decrease in hardware revenue –– as the prior-year period included significantly more hardware revenue under our material cell phone provider contract noted above. We received $263,000 of hardware revenue and $147,000 of monitoring revenue from the provider in Q2’26, as compared to $1,338,000 of hardware revenue and $102,000 of monitoring revenue in Q2’25. Total monitoring revenue, which is amortized over a service period of typically one year, grew 8.0% to $1,425,000 in Q2’26, reflecting continued growth in monitored endpoints. For the first six months of 2026, total revenue was $4,716,000 vs. $6,623,000 in 6M’25, also reflecting steady growth in monitoring revenue offset by variability in hardware revenue, principally related to large shipments under the material contract in the year-ago period.

Q2’26 gross profit was $2,050,000, reflecting 82.4% gross margin, compared to gross profit of $2,639,000 and gross margin of 74.9% in Q2’25. The margin improvement was principally driven by a greater portion of monitoring revenue, with a 95.6% gross margin in Q2’26 and a 94.6% gross margin in Q2’25, as a percentage of total revenue.

Operating expenses decreased 1.0% to $1,675,000 in Q2’26 versus $1,692,000 in Q2’25, due a $26,000 decrease in research and development (R&D) expense, offset by a $9,000 increase in selling, general and administrative (SG&A) expense. The slight increase in SG&A reflected higher stock-based compensation and personnel expenses, offset by lower commissions related to lower hardware sales. Lower R&D expense primarily reflected the tailing-off of investment related to the completion of Omni and OmniPro product development in 2025, prior to the commencement of our next product initiative.

Lower revenue, partially offset by slightly lower operating expenses, resulted in Q2’26 net income attributable to Acorn stockholders of $294,000, or $0.12 per diluted share, compared to net income of $720,000, or $0.28 per diluted share, in Q2’25. Q2’26 included $99,000 of non-cash, stock-based compensation expense vs. $32,000 in Q2’25. Net income to attributable to Acorn stockholders in the 6M’26 period was $217,000, or $0.09 per diluted share, as compared to $1,184,000, or $0.47 per diluted share, in 6M’25. Net income in 6M’26 included $296,000 of non-cash, stock-based compensation expense vs. $93,000 in 6M’25.

Liquidity and Cash Flow

Excluding deferred revenue of $2,722,000, which has no impact on future cash flow, net working capital was $6,410,000 at June 30, 2026 versus $6,254,000 at December 31, 2025. This included cash of $4,478,000 at June 30, 2026 versus $4,454,000 at year-end 2025.

Through the first half of 2026, Acorn generated $277,000 of cash from operating activities, used $263,000 for investing activities (including $250,000 in Q1 related to the new OMNI360 solutions suite), and received $10,000 from financing activities related to the exercise of stock options––for a net increase in cash of $24,000.
