Risk factors and legal proceedings

The risks Ideal Power Inc. names in Item 1A of its 10-K filed Mar 27, 2026: 26 risks under these headings, as written.4

  • We are subject to various risks that may materially harm our business, prospects, financial condition and results of operations. An investment in our common stock is speculative and involves a high degree of risk. In evaluating an investment in shares of our common stock, you should carefully consider the risks described below, together with the other information included in this report.
  • Risks Related to the Company
  • We lack an established operating history on which to evaluate our business and determine if we will be able to execute our business plan. We have also incurred losses in prior periods, expect to incur losses in the future, currently generate limited commercial revenue and we may not achieve or maintain profitability in the future.
  • Product development and commercialization is an inherently uncertain process, and we may encounter unanticipated development and/or commercialization challenges and may not be able to meet our product design and/or commercialization milestones.
  • Our semiconductor fabrication partners may be unable to successfully and cost-effectively develop and implement new process steps necessary for bidirectional semiconductor device fabrication at scale.
  • We, or our potential future licensees, must achieve design wins to obtain customers, although design wins achieved may not necessarily result in substantial sales or licensing revenue to us.
  • We previously received grant funds from the United States for the development of a bidirectional switch. In certain instances, the United States may obtain title to inventions related to this effort. If we were to lose title to those inventions, we may have to pay to license them from the United States in order to manufacture the inventions. If we were unable to license those inventions from the United States, it could slow down our product development.
  • As we continue to grow and to develop our intellectual property, we could attract threats from patent monetization firms or competitors alleging infringement or competitors could infringe upon our intellectual property. We may incur substantial costs as a result of litigation or other proceedings relating to patent and other intellectual property rights.
  • We may license our technology in the future; however the terms of any such agreements may not prove to be advantageous to us. If the license agreements we may enter into do not prove to be advantageous to us, our business and results of operations will be adversely affected.
  • Future revenue may rely on the marketing and sales efforts of third parties whom we do not control.
  • A material part of our success depends on our ability to manage third-party resources. Our failure to properly select, manage and retain qualified third-party resources could materially and adversely affect our results of operations and relations with our partners and future customers.
  • Supply chain disruptions and barriers to trade, such as tariffs, could interrupt product manufacturing and global logistics and increase product costs.
The other 15 risks
  • Changes in U.S. trade policies, the imposition of tariffs by the U.S. and retaliatory responses from other countries may significantly increase our costs of production and materially and adversely affect our business.
  • Our ability to successfully commercialize our products and future operating results depend on the continued growth of our target markets and related technologies.
  • We will need additional financing to execute our business plan and fund operations, which additional financing may not be available on commercially reasonable terms or at all.
  • A failure to obtain additional government grants could have a material adverse effect on our development efforts and our ability to fund operations and execute on our business plan.
  • We are highly dependent on the services of key members of our management and technical teams. Our inability to retain these individuals could impede our business plan and growth strategies, which could have a negative impact on our business and the value of your investment.
  • Our operating results for any quarterly reporting period may fluctuate significantly depending on the timing and pace of our development spending and costs to commercialize our technology.
  • New technologies in the power semiconductor switch industry may supplant our technology in this market, which would harm our business and operations, and we may not be able to compete effectively in this industry and with any such new technologies.
  • We may not be able to use some or all of our net operating loss carryforwards to offset future income.
  • Risks Related to Owning Our Common Stock
  • The public market for our common stock may be volatile. This may affect the ability of our investors to sell their shares as well as the price at which they sell their shares.
  • We have the right to issue, and have in the past issued, shares of preferred stock. If we were to issue additional preferred stock, it may have rights, preferences and privileges that may adversely affect the common stock.
  • We have not paid dividends in the past and have no immediate plans to pay dividends.
  • Shares eligible for future sale, including pre-funded warrants and options exercisable into shares of our common stock and restricted stock units and performance stock units subject to future vesting, may cause dilution to our existing stockholders and may adversely affect the market for our common stock.
  • Raising additional capital, as necessary, may cause dilution to our existing stockholders, restrict our operations or require us to relinquish rights to our technologies.
  • Our charter documents and Delaware law may inhibit a takeover that stockholders consider favorable.
  • If securities or industry analysts do not publish or do not continue to publish research or reports about our business, or if they issue an adverse or misleading opinion regarding our stock, our stock price and trading volume could decline.

Legal proceedings

We may be subject to litigation from time to time in the ordinary course of business. We are not currently party to any legal proceedings.
