Previous wording
We have had significant losses and negative cash flows in nearly every year since inception, and continue to have an accumulated deficit which, at December 31, 2024, was approximately $448.2 million. Our net loss for the year ended December 31, 2024 was approximately $14.5 million, compared to net income for the year ended December 31, 2023 of $9.5 million. Our independent registered public accounting firm has included in their audit opinion on our consolidated financial statements as of and for the year ended December 31, 2024, a statement with respect to substantial doubt about our ability to continue as a going concern. Note 2 to our consolidated financial statements included in Item 8 includes a discussion regarding our liquidity and our ability to continue as a going concern. Our consolidated financial statements have been prepared assuming we will continue to operate as a going concern, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. If we become unable to continue as a going concern, we may have to liquidate our assets and the values we receive for our assets in liquidation or dissolution could be significantly lower than the values reflected in our consolidated financial statements. The substantial doubt as to our ability to continue as a going concern may adversely affect our ability to negotiate reasonable terms with our vendors and may adversely affect our ability to raise additional capital in the future.

Previous wording
Because we have a history of net losses and negative cash flow from operations, we have funded our operating costs primarily from the sale of debt and equity securities, including our secured and unsecured contingent debt obligations. Our current capital resources include cash and cash equivalents of $4.9 million at December 31, 2024, which will not be sufficient to meet our working capital needs for the twelve months after issuance of our consolidated financial statements. Our business plan will continue to require expenditures for patent protection and enforcement and general operations. If we do not generate sufficient revenues from our licensing and patent enforcement programs, we will require additional capital to fund our operations. Additional capital may be in the form of debt securities, the sale of equity securities, including common or preferred stock, additional litigation funding, or a combination thereof. Failure to raise additional capital may have a material adverse impact on our ability to achieve our business objectives.

Previous wording
We have $3.5 million in outstanding principal under convertible notes at December 31, 2024. If we fail to comply with the various covenants set forth in each of the notes, including failure to pay principal or interest when due or consummating a change in control, we could be in default thereunder. Upon an event of default under each of the notes, the interest rate of the notes will increase to 12% per annum and the outstanding principal balance of the notes plus all accrued unpaid interest may be declared immediately payable by the holders. We may not have sufficient available funds to repay the notes upon an event of default, and we cannot provide assurances that we will be able to obtain other financing at terms acceptable to us, or at all.

Previous wording
We have cumulative net operating loss carryforwards (“NOLs”) totaling approximately $270.8 million at December 31, 2024, of which $230.1 million is subject to expiration in varying amounts from 2025 to 2037. Our ability to fully recognize the benefits from those NOLs is dependent upon our ability to generate sufficient income prior to their expiration. In addition, our NOL carryforwards may be limited if we experience an ownership change as defined by Section 382 of the Internal Revenue Code (“Section 382”). In general, an ownership change under Section 382 occurs if one or more 5% shareholders increase their collective ownership of the aggregate amount of our outstanding shares by more than 50 percentage points over a relevant lookback period. We have sold a significant number of equity securities over the relevant lookback period which increases the risk of triggering an ownership change under Section 382 from the future sale of additional equity securities. An ownership change under Section 382 will significantly limit our ability to utilize our tax benefits.

Previous wording
Since 2011, we have spent a significant amount of our financial and management resources to pursue patent infringement litigation against third parties. We believe this litigation, and other litigation matters that we may in the future determine to pursue, will continue to consume management and financial resources for long periods of time. There can be no assurance that our current or future litigation matters will ultimately result in a favorable outcome for us or that our financial resources will not be exhausted before achieving a favorable outcome. In addition, even if we obtain favorable interim rulings or verdicts in particular litigation matters, they may not be predictive of the ultimate resolution of the matter. Unfavorable outcomes could result in exhaustion of our financial resources and could hinder our ability to pursue licensing and/or product opportunities for our technologies in the future. Failure to achieve favorable outcomes from one or more of our patent enforcement actions will have a material adverse impact on our financial condition, results of operations, cash flows, and business prospects.

Previous wording
Our licensing and enforcement activities are subject to numerous risks from outside influences, including new legislation, regulations and rules related to obtaining or enforcing patents. For instance, the U.S. has enacted sweeping changes to the U.S. patent system including changes that transition the U.S. from a “first-to-invent” to a “first-to-file” system and other changes that alter the processes for challenging issued patents. To the extent that we are unable to secure patent protection for our future technologies and/or our current patents are challenged such that some or all of our protection is lost, we will suffer adverse effects to our ability to offer unique products and technologies. As a result, there would be an adverse impact on our financial position, results of operations and cash flows and our ability to execute our business plan.

At December 31, 2024, we had 114.0 million shares of common stock outstanding and had outstanding options and warrants for the purchase of up to 35.2 million additional shares of common stock, of which approximately 34.4 million were exercisable as of December 31, 2024. In addition, as described more fully below, holders of convertible notes may elect to receive up to 27.7 million shares of common stock upon conversion of the notes, and we may elect to pay accrued interest on the notes in shares of our common stock. The majority of the shares of common stock underlying these securities are currently registered for sale to the holder or for public resale by the holder. The amount of common stock reserved for issuance may have an adverse impact on our ability to raise capital and may affect the price and liquidity of our common stock in the public market. In addition, the issuance of these shares of common stock will have a dilutive effect on current shareholders’ ownership.
Current wording
At December 31, 2025, we had 143.2 million shares of common stock outstanding and had outstanding options, restricted share units, and warrants for the purchase of up to 29.3 million additional shares of common stock, the majority of which were exercisable as of December 31, 2025. In addition, as described more fully below, holders of convertible notes may elect to receive up to 24.7 million shares of common stock upon conversion of the notes, and we may elect to pay accrued interest on the notes in shares of our common stock.

Previous wording
We have an aggregate principal amount of $3.5 million in convertible notes outstanding at December 31, 2024. The notes are convertible into shares of our common stock at fixed conversion prices, which may be less than the market price of our common stock at the time of conversion. If the entire principal were converted into shares of common stock, we would be required to issue an aggregate of up to 27.7 million shares of common stock. If we issue all of these shares, the ownership of our current shareholders will be diluted.

Further, we may elect to pay interest on the notes, at our option, in shares of common stock, at a price equal to the then-market price for our common stock. From 2018 to 2024, we issued an aggregate of approximately 9.3 million shares of common stock as in-kind interest payments on our convertible notes. We currently do not believe that we will have the financial ability to make payments on the notes in cash when due. Accordingly, we currently intend to make such payments in shares of our common stock to the greatest extent possible. Such interest payments could further dilute our current shareholders.

The trading price of our common stock has been and may continue to be volatile. Between January 1, 2023 and March 1, 2025, the reported high and low sales prices for our common stock ranged between$0.07 and $1.18 per share. The price of our common stock may continue to be volatile as a result of a number of factors, some of which are beyond our control. These factors include, but are not limited to, developments in outstanding litigation, our performance and prospects, general conditions of the markets in which we compete, and other economic and financial conditions. Such volatility could materially and adversely affect the market price of our common stock in future periods.
