Properties, in its own words

OmniMetrix’s activities are currently conducted in approximately 21,000 square feet of office and production space in the Hamilton Mill Business Park located in Buford, Georgia, under a lease that was amended on June 20, 2025 to extend the lease term through November 30, 2030. The annual operating lease expense was $184,000 in 2025 and $129,000 in 2024. For 2026, the annual operating lease expense will be $216,000 for the year ending through December 31, 2026. OmniMetrix is currently utilizing only a portion of these leased facilities.

On July 6, 2021, the Company entered into an agreement with King Industrial Realty, Inc. to sublease from the Company 1,900 square feet of the Company’s 21,000 square feet office and production space in the Hamilton Mill Business Park located in Buford, Georgia. This sublease was amended on August 15, 2025 to extend the term through September 30, 2028 and to provide a monthly sublease payment of $3,374 plus annual escalators (the average monthly sublease payment in 2025 was $2,790), which includes the base rent plus a pro-rata share of utilities, property taxes and insurance. Fifty percent of any excess rent received above the per square foot amount that the Company pays will be remitted to the Company’s landlord less the allocation of any shared expenses and leasehold improvements specific to the sublease. After the offset of the investment in leasehold improvements and other expenses related to the sublease, the total amount payable to our landlord under the sublease was $8,295 for the year ended December 31, 2025, and $6,680 for the year ended December 31, 2024.

The rest of Item 2

Below are the future payments (in thousands) expected to be received from King Industrial Realty, Inc. under the sublease. The Company expects to remit fifty percent of these amounts net of the annual service cost of approximately $2,600 to our landlord.

Risk factors and legal proceedings

The risks Acorn Energy names in Item 1A of its 10-K filed Mar 5, 2026: 20 risks under these headings, as written.16

  • General Factors
  • We depend on key management for the success of our business.
  • Loss of the services of a few key employees could harm our operations.
  • Compliance with changing regulations of corporate governance, public disclosure and financial accounting standards may result in additional expenses and affect our reported results of operations.
  • We may not be able to successfully integrate companies which we may invest in or acquire in the future, which could materially and adversely affect our business, financial condition, future results and cash flow.
  • If we are unable to protect our intellectual property, or our intellectual property protection efforts are unsuccessful, others may duplicate our technology.
  • Our financial instruments could subject us to concentrations of credit risk.
  • International trade policies, including tariffs, sanctions and trade barriers may adversely affect our business, financial condition, results of operations and prospects.
  • We are dependent on information technology and our systems and infrastructure face certain risks, including cybersecurity breaches and data leakage.
  • Risks Related to OmniMetrix
  • An increase in customer terminations would negatively affect our business by reducing OmniMetrix’s revenue or requiring us to spend more money to grow our customer base.
  • OmniMetrix is a relatively small company with limited resources compared to some of its current and potential competitors, which may hinder its ability to compete effectively.
The other 10 risks
  • OmniMetrix may not be able to access sufficient capital to support growth.
  • OmniMetrix sells equipment and services which monitor third-party products; thus, its revenues are dependent on the continued sales of such third-party products.
  • If OmniMetrix is unable to keep pace with changing markets or customer-mandated product and service improvements, OmniMetrix’s results of operations and financial condition may suffer.
  • The cellular networks used by OmniMetrix are also subject to periodic technical updates that may require corresponding updates to, or replacement of, OmniMetrix’s monitoring equipment.
  • A substantial portion of OmniMetrix’s revenues is expected to be generated not from product sales, but from periodic monitoring fees and thus it is continually exposed to risks associated with its customers’ financial stability.
  • OmniMetrix’s ability to provide, and to collect revenues from, monitoring services is dependent on the reliability of cellular networks not controlled by OmniMetrix.
  • OmniMetrix’s business is dependent on its ability to reliably store and manage data, but there can be no guarantee that it has sufficient capabilities to mitigate potential data loss in all cases.
  • Risks Related to Our Securities
  • Our stock price is highly volatile, and we do not expect to pay dividends on shares of our common stock for the foreseeable future. Investors may never obtain a return on their investment.
  • Our share price may decline due to the large number of shares of our common stock eligible for future sale in the public market including shares underlying options.
  • We may have to offer additional securities for sale in the near future.
