Acorn Energy's second quarter of 2026 marked a return to bottom-line profitability and inflection toward new growth engines as the large cell phone contract finished cycling through year-over-year comparisons. Total revenue declined to $2,489,000 from $3,525,000 a year earlier because the prior-year quarter had captured the final major hardware shipments under the material contract, but recurring monitoring revenue grew 8% to $1,425,000 at a greater-than-90% gross margin, driving overall gross margin up 750 basis points to 82.4%. Net income was $294,000 ($0.12 per diluted share) and the OmniMetrix operating subsidiary produced $722,000 of operating income, nearly double the prior quarter, while the company stayed debt-free with $4,478,000 of cash. Two initiatives dominated the call: the formal launch of OMNI360, an all-in-one cell tower campus monitoring and control platform offered in three tiers (Nova, Horizon, Zenith) with a 24/7 network operating center and AI-supported software, and a new Champion Power Equipment partnership making OmniMetrix the standard monitoring option on Champion's aXis and fleX home standby generators. Management framed a large addressable opportunity — roughly 235,000 North American cell towers and an estimated $500 million of industry-wide tower theft losses in 2026 — kept its near-term focus on cell towers rather than data centers, and reaffirmed its ~20% average annual revenue-growth target with strong incremental operating leverage. It expects more favorable year-over-year comparisons in the second half of 2026, aided by the Champion partnership beginning to contribute in the current quarter, while blended gross margin normalizes toward ~75% as hardware volumes rebuild.

Thank you, Tracy. Good morning, everyone. Thank you for participating on today's call. Our second quarter results demonstrate the underlying strength of our business model, centered on high-margin recurring monitoring revenue driven by a growing base of hardware deployments, which can be variable in their size and timing. As expected, our year-over-year revenue comparison was impacted by strong year-ago hardware deployments related to the material cell phone contract. Total second quarter revenue of $2.49 million reflected 8% growth in monitoring revenue, which is our highest margin and most predictable revenue stream. Hardware revenue was $1.06 million in the second quarter versus $2.21 million in Q2 last year.
The year-ago period reflected over $1.3 million in hardware revenue related to the last significant shipments and the fulfillment of the initial purchase orders under the material contract, as compared to follow-on purchase orders for hardware, which resulted in revenue from the cell phone provider totaling $263,000 in this Q2 2026. Our Q2 gross margin improved by 750 basis points to over 82%, principally driven by the increase in monitoring revenue as a percentage of total revenue. Monitoring generated a gross margin of over 90% in the quarter, though moving forward, I would expect our blended gross margin to average more in the 75% range as we make progress in expanding hardware deployments. On the bottom line, we reported second quarter net income of $294,000 or $0.12 per diluted share.
For the first six months, our net income was $217,000, or $0.09 per diluted share. These results reinforce our ability to maintain solid profitability and cash generation while investing in future growth. For example, in the residential market, we are advancing our growth potential through a new partnership with Champion Power Equipment. The collaboration makes our monitoring and control solution the standard monitoring option on their popular aXis and fleX lines of home standby generators. Champion has a strong reputation for reliable, high-quality, and competitively priced portable generators, which have sold millions of units over the years. Recently, Champion has developed whole home solutions featuring advanced technologies such as fleX for better load management and fuel efficiency, durable all-aluminum enclosures for weather resistance with extended warranties.
By integrating our monitoring capabilities as the standard option, Champion customers can gain real-time visibility into generator status, fuel levels, battery condition, maintenance alerts, and remote control options through our OmniView interface. Given Champion's accelerating growth in the residential standby generator market, we believe this partnership provides significant long-term growth potential that should begin contributing to our results in the current quarter. Pricing under the agreement is based on an assumed annual purchase volume of 3,000 units, but the agreement does not obligate Champion to purchase a minimum quantity. Champion is planning to issue a press release today regarding this partnership. Turning to another exciting initiative that could have a transformative impact on our business. We are particularly thrilled about the formal launch of OMNI360, our comprehensive remote monitoring and control platform for cell tower campus security and other critical infrastructure.
After investing several months in customization, product enhancements, and integration, OMNI360 is now available in three tiers, Nova, Horizon, and Zenith, offering different capability levels and each backed by a 24/7 network operating center, a sophisticated AI-supported software suite and mobile asset access. OMNI360 delivers a much broader suite of capabilities that builds on our industry-leading generator-focused solutions to provide unified turnkey management of an entire site. Capabilities include advanced environmental monitoring control, temperature, humidity, HVAC, smoke detection, and flood sensors, robust campus security with AI-powered cameras, site access control, intrusion sensing, two-way audio, and live incident response. It includes comprehensive power management solutions such as fuel level sensing and usage prediction, commercial power automatic, transfer switch monitoring, battery health, transformer temperature and voltage, current balance, imbalance detection, along with smart energy and cooling optimization tools.
OMNI360's all-in-one approach delivers real-time visibility, automated controls, and actionable insights that help operators cut energy costs, reduce unnecessary truck rolls, prevent theft, and ensure compliance. What makes OMNI360 particularly exciting is that it is the only solution that brings together all of these functions into one platform and provides 24/7 monitoring and support. While there are a range of hardware solutions already in the market, they are typically limited to just a few functions, and they do not include a monitoring capability. We believe these limitations create very exciting opportunities for a more robust solution that also delivers mission-critical real-time data and controls to cell tower owners and tenants. We are actively introducing OMNI360 across the industry. For example, we'll showcase it at this year's ISE EXPO, a gathering of telecom sector leaders taking place in Nashville later this month.
While the breadth of the solution and typical enterprise sales processes suggest a longer sales cycle, early feedback has been very positive, and we see substantial potential in this market. In addition to these efforts, we remain active in seeking and reviewing complementary accretive M&A opportunities using a very disciplined financial and operational framework. Once we've identified an appropriate target that meets our operational criteria, the challenge is in negotiating appropriate terms that create value for shareholders. We have lost out in several situations where another bidder was willing to pay substantially more than we thought the assets could justify, and we are unwilling to take such risks. By their nature, discussions of this type can take many months, and the outcomes are impossible to predict until the very end. As a result, there's little we can say while discussions progress.
The same is true for our efforts to secure OEM bundling opportunities, which we continue to pursue as we believe these are worthwhile efforts to continue to increase our number of monitoring connections. The secular tailwinds supporting our business remain in place. Increasing frequency of severe weather events, combined with growing power demand from AI data centers, electrification, and reshoring, continue to highlight the critical need for resilient infrastructure. In just the past few weeks, extreme heat and thunderstorms have strained the U.S. power grid, causing hundreds of thousands of outages across multiple regions. These events underscore both the vulnerability of the grid and the value of reliable backup systems and remote monitoring. Additionally, attacks on critical communications infrastructure reached record levels in 2025, and we estimate that cell tower theft losses will reach approximately $500 million industry-wide in 2026, including copper and equipment theft.
OMNI360 is purpose-built to help operators combat these exact challenges, increasing reliability, security, and operational efficiency. Also today, one year in, AI already represents 4% of all cell network traffic. Imagine what it'll be in three years. This points to the critical importance of protecting cell towers and related infrastructure. Looking ahead, we remain very optimistic about our long-term growth potential. 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 and earnings comparisons moving forward. Combined with the momentum in our monitoring base, the launch of OMNI360, the Champion partnership, our internal sales strategies, and our ongoing M&A and OEM efforts, we believe we have the pieces in place to achieve growth that more than exceeds and aligns with our three to five-year target of approximately 20% average annual revenue growth.
Further, our capital-light, high margin, recurring revenue model and significant NOLs give us strong operating leverage, allowing us to drive meaningful incremental profitability as we scale. We are very enthusiastic about the progress across all fronts and the opportunities that lie ahead for Acorn and OmniMetrix. I will turn to Tracy for her financial and operational insights.
Thank you, Jan. A theme for our Q2 2026 results is the steady progression of recurring monitoring revenue and our strong gross margin performance. On lower revenues, OmniMetrix, our operating subsidiary, again delivered solid profitability with operating income of $722,000 in Q2 2026 versus $1.2 million in Q2 2025, and significantly better than $395,000 in Q1 2026. I will touch on a few key points. Total revenue was $2,489,000, down from $3,525,000 in Q2 2025 and up from $2,227,000 in Q1 2026.
This year-over-year decline stemmed from a $1,141,000 decrease in hardware revenue, which was due to the impact of the sales last year under the material contract that were largely fulfilled prior to 2026, partially offset by $105,000 rise in monitoring revenue. Monitoring revenue rose 8% to $1,425,000 as our installed base of monitored endpoints continued to expand. Hardware revenue of $1,064,000 included $1,000,011 from sales of new hardware and accessories, and $53,000 from the amortization of deferred hardware revenue. Amortization of deferred revenue was $270,000 in the prior year period, a year-over-year variance of $217,000. We expect to recognize our remaining deferred hardware balance of $5,000 in Q3 2026, which will be compared to $215,000, which was recognized in Q3 2025.
Gross margin increased 750 basis points to 82.4%, from 74.9% in Q2 2025, reflecting the higher relative contribution of monitoring revenue, which resulted in gross margin greater than 90% in the quarter. Operating expenses declined 1% to $1,675,000 from $1,692,000, with R&D expense decreasing by $26,000, partially offset by slightly higher SG&A expense. The modest SG&A increase reflected higher stock-based compensation and personnel costs, partially offset by lower commissions on reduced hardware volume. The decline in R&D expense primarily reflected lower spending after the completion of OMNI and OMNIPRO product development in 2025, prior to the start of our next product initiative.
OmniMetrix segment operating income, the combined operating results of our PG, CP, and IS segments, the IS segment being the infrastructure solution segment, was $722,000, demonstrating the profitability of our core operating subsidiary, even after absorbing approximately $30,000 of operating expense in our pre-revenue infrastructure solution segment. On a consolidated basis, including unallocated corporate headquarters costs, we reported net income 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 the year-ago quarter. Q2 2026 results included $99,000 of non-cash stock-based compensation expense versus $32,000 in Q2 2025. For the six months ended June 30th, 2026, net income to Acorn stockholders was $217,000 or $0.09 per share, compared to $1,184,000 or $0.47 per share in the first half of 2025.
Six months results included $296,000 of non-cash stock-based compensation expense versus $93,000 in the prior year period. Looking at liquidity and cash flow, our cash balance was $4,478,000 at June 30th. Excluding deferred revenue of $2.7 million, our net working capital improved to $6.4 million versus $6.25 million at December 31, 2025, and we remain debt-free. In the first half of 2026, we generated $277,000 of cash from operating activities, used $263,000 in investing activities, including the $250,000 related to the exclusive license agreement for OMNI360, and received $10,000 from financing activities tied to the exercise of stock options, producing a net cash increase of $24,000. With respect to our deferred tax asset, we continue to maintain a partial valuation allowance of $10.3 million, leaving a meaningful base of NOL and capital loss carryforwards to enhance cash flows to support future growth and potential M&A initiatives.
We're very excited about our new product and other strategic opportunities we discussed, as well as the prospect of returning to top-line year-over-year growth comparisons in the second half of 2026. Operator, you may now prepare the lines for questions. Thank you.
