Wilmington, DE – August 7, 2025 – Acorn Energy, Inc. (Nasdaq: ACFN), a provider of remote monitoring and control solutions for backup generators, gas pipelines and other critical infrastructure assets, announced results for its second quarter ended June 30, 2025 (Q2’25). Acorn will hold an investor call today at 11 a.m. ET (details below).

Summary Financial Results

CEO Commentary

Jan Loeb, Acorn’s CEO, said, “Our Q2 results reflect the strength of our technology and solutions as well as the operating leverage of our high-margin business model. Our business is fueled by hardware sales that create recurring revenue streams from annual monitoring contracts, 90% or more of which typically renew each year. Given the modest incremental investment required to scale our business, we expect approximately 50% of each incremental revenue dollar to drop to our operating income line for the foreseeable future.

“Our results continue to benefit from an estimated $5.4M contract to provide monitoring equipment plus an initial year of monitoring services for 5,000 -10,000 cell tower backup generators for a national cellular phone provider which we refer to as the Material Contract. The monitoring hardware rollout is progressing well, and we expect to complete all hardware deliveries by the end of 2025. We recognize hardware revenue upon delivery and customer acceptance, while monitoring revenue is deferred and then amortized over 12 months. The contract contributed $1.4M of revenue in Q2’25 and a total of $4.1M since inception in Q4’24, approximately 95% of which relates to hardware sales thus far.

“Several factors are expected to drive demand for backup power generation and our remote monitoring services in the coming years. Most importantly, growing energy demand is taxing our aging grid infrastructure, resulting in increasing reliability challenges for electricity access. In addition, a growing incidence of extreme weather events and natural disasters that disrupt electricity access for days, weeks and sometimes months, further underscores the critical importance of reliable backup power. These factors are contributing to increasing awareness, interest and demand for backup power and remote monitoring solutions that ensure their proper functioning across commercial, industrial, and residential applications.

“As a pioneer and technology leader in remote monitoring solutions, OmniMetrix is primed to scale our base of monitored endpoints in step with the expected growth in standby generator deployments. At the same time, we continue to invest in developing new products as well as enhancing our industry-leading solutions to deliver the greatest possible value to our growing base of customers.

“We’ve been working diligently to ensure the success of our large cell tower rollout, demonstrating our market leadership and creating momentum for expanded collaborations and other large-scale deployment opportunities. Our internal sales team focuses on large commercial and industrial customer opportunities, and we access the residential market through our network of approximately 600 generator dealers in North America. We are also seeking to forge strategic relationships with one or more OEMs to extend our market reach. Additionally, we continue to evaluate possible M&A opportunities that are closely aligned with our business model and have the potential to be meaningfully accretive. These initiatives require discipline, patience, and persistence and, therefore, it’s not possible to predict timing or outcomes, but we want you to be aware of these areas of focus.

“Subsequent to quarter-end, we completed an uplisting to the Nasdaq Capital Market, a significant milestone for our company. The Nasdaq listing should benefit our shares and shareholders by enhancing our visibility, attracting a broader base of investors and improving trading liquidity of our shares thereby supporting growth through potential M&A opportunities.”

Financial Review

Q2’25 revenue rose 55% to $3,525,000 vs. Q2’24, reflecting an 89% increase in hardware revenue and a 19% increase in monitoring revenue. Hardware growth was principally due to $1,338,000 in sales of monitoring equipment related to our Material Contract. Growth in monitoring revenue was driven by an increase in total monitored units in Q2’25 as compared to the year-ago period. For the six months ended June 30, 2025, revenue grew 50% to $6,623,000 versus the prior-year period, due to the same factors.

Q2’25 gross profit grew 58% to $2,639,000 vs. Q2’24, principally reflecting higher revenue and a Q2’25 gross margin of 75%.

Operating expenses increased 20% to $1,692,000 in Q2’25 vs. $1,407,000 in Q2’24, due to a $246,000 increase in selling, general and administrative (SG&A) expenses and a $39,000 increase in research and development (R&D) expenses. However, operating expenses decreased to 48% of total revenue in Q2’25 from 62% of total revenue in Q2’24, as revenue growth outpaced expense increases. The increase in SG&A expenses reflects a $100,000 increase in commission expense related to the Material Contract, a $48,000 increase in personnel expenses due to staff additions and compensation increases, a $39,000 increase in technology fees and expenses, as well as a $59,000 increase in tax and audit professional fees and other corporate/public company expenses. Higher R&D expenses reflect the hiring of a senior-level engineer in November 2024 and salary increases, as well as increased investment in next-generation monitoring products, as well as the exploration of new products and product lines.

Reflecting revenue growth and operating leverage, Q2’25 net income attributable to Acorn stockholders improved to $720,000, or $0.28 per diluted share, from $271,000, or $0.11 per diluted share, in Q2’24. Net income for the first six months of 2025 increased to $1,184,000, or $0.47 per diluted share, as compared to $336,000, or $0.13 per diluted share, in the prior-year period. As of Q4’24, Acorn began reporting on a fully taxable basis though its earnings are shielded from federal income taxes on a cash basis due to its substantial net operating loss carryforwards. Income tax expense was $242,000, or $0.10 per share in Q2’25 vs. zero in Q2’24. Likewise, income tax expense was $396,000, or $0.16 per share, in the first six months of 2025, compared to $25,000, or $0.01 per share, in the prior-year period.

Liquidity and Cash Flow

Excluding deferred revenue of $3,155,000 and deferred cost of goods sold of $223,000, which have no impact on future cash flows, net working capital improved to $5,661,000 at June 30, 2025 from $4,230,000 at December 31, 2024. Acorn’s cash position increased to $3,253,000 at the close of Q2’25 versus $2,591,000 at the close of Q1’25 and $2,326,000 at year-end 2024.

Through the first six months of 2025 Acorn generated $900,000 of cash from operating activities, used $21,000 in investing activities and received proceeds of $48,000 from the exercise of Company stock options. The resulting net increase in cash of $927,000 compares to $14,000 generated in the first half of 2024.
