There can be no assurances that the company will meet its growth targets or other strategic goals and objectives. In 2025, Acorn Energy achieved record revenue, improved operating income, higher cash flow, and our third straight year of profitability. Our performance benefited from a 22% increase in high-margin monitoring revenue, driven by continued growth in our installed base of remote monitoring endpoints. Our year-over-year Q4 and full year comparisons reflect the benefit of a national cell phone provider contract, the largest in our history.
The bulk of hardware revenue for this contract was recorded between Q3 of 2024 and Q2 of 2025, contributing to lower year-over-year hardware revenues in the second half of 2025. Acorn's 2025 results reflected $956,000 in revenue from amortization of deferred hardware revenue, a 48% decrease from the $1.84 million recorded in 2024, but with no impact on cash generation. This revenue impact will end this year as we expect the balance of deferred hardware revenue of $168,000 to be fully amortized by August of 2026. Our belief is that consumer generator demand is likely to return to more historic levels as impending factors moderate.
Turning to our strategies for growth, we reviewed five complementary core initiatives in today's press release on which I'd like to provide a little more color. One of the larger generator manufacturers has publicly stated they expect a 10% increase in residential generated sales in 2026, we expect to benefit if this does indeed occur. They provide best-in-class technology and cloud-based business intelligence platforms that are successfully deployed at over 110,000 sites in 15 countries. As we will be sharing SaaS revenue with AIO, it is too early to project what our margins will be.
| Metric | Period | Current guidance |
|---|---|---|
| Long-term revenue growth | Next 3-5 years | Reaffirmed ~20% average annual revenue growth over the coming three to five years |
| Incremental operating leverage | Ongoing | ~50% of each incremental revenue dollar from the existing business expected to flow through to operating income |
| AIO / Infrastructure Solutions revenue | 2H 2026 | No revenue expected from the AIO partnership until the second half of 2026 |
| Deferred hardware amortization | Through August 2026 | Remaining $168,000 of deferred hardware revenue expected to be fully amortized by August 2026 |
| Residential market | 2026 | One large generator manufacturer publicly expects a ~10% increase in residential generator sales in 2026, from which Acorn expects to benefit |
| Metric | YoY | Note |
|---|---|---|
| Total revenue | $11,478K (+4.5%) | 22% monitoring growth partially offset by an 8% hardware decline from contract timing and lower deferred-revenue amortization. |
| Monitoring revenue | +22% | Expansion of the installed base of monitored endpoints; ~95% gross margin. |
| Gross margin | 76.8% vs 72.8% (+400 bps) | Higher monitoring mix plus hardware-margin gains from next-generation product cost efficiency. |
| Operating cash flow | $2,090K (+131%) | Higher-quality earnings and working-capital timing; year-end cash up $2.1M to $4,454K. |
| Diluted EPS | $0.99 vs $2.51 | Prior year included a much larger ($1.77/share) non-cash deferred-tax benefit. |
| Topic | Previous mention | Current period | Trend |
|---|---|---|---|
| AIO (All In One) partnership | — | A transformative, capital-light 'semi-acquisition' of North American rights structured as a modest upfront fee plus an ongoing monitoring revenue share (an earn-out); OmniMetrix keeps the hardware sale and brands the products, targeting cell towers first (theft, power, environmental and security monitoring), then data centers and utilities. | — |
| Five growth initiatives | — | Large C&I sales; OEM white-label bundling (still expects at least one of three OEMs); residential via 600+ dealers; R&D/new products; and accretive M&A (AIO emerged from the M&A pipeline; two other prospects remain but priced too far apart). | — |
| NOLs / balance sheet | — | $14.4 million of NOL and capital-loss carryforwards (most expiring 2031 or later) with a $10.3 million valuation allowance are viewed as a strategic asset to shelter growth and potential M&A; released an additional $464,000 of allowance in 2025. | — |
| Secular tailwinds | — | AI/data-center demand, electrification, EV adoption and reshoring straining an aging grid, plus severe weather (e.g., late-January ice storms leaving 1M+ without power), reinforce demand for backup power and remote monitoring. | — |
