Current report
On January 28, 2026, the CERT defendants filed a notice of appeal of the judgment. Under applicable rules, the CERT defendants may seek a stay of execution of the judgment pending appeal by posting a bond or other security in an amount and form approved by the Court. As of the date of this report, the CERT defendants have not obtained a bonded stay. Although the automatic stay of execution applicable following entry of judgment has expired, the appeal remains pending. As a result, there can be no assurance regarding the timing or amount of any recovery, if any, from the judgment, or that the judgment will ultimately be upheld on appeal. Interest continues to accrue on the judgment amount during the pendency of the appeal.
Current report
We are currently subject to inter partes review proceedings that could adversely affect the enforceability of our patent rights.
Current report
Certain of our patents which pertain to mercury removal from coal-fired power plants are currently the subject of inter partes review (“IPR”) proceedings before the United States Patent and Trademark Office. IPR proceedings are a mechanism by which third parties can challenge the validity of issued patents, and they have become a frequent tool used by parties seeking to invalidate patents in our industry. Even though a jury has upheld the validity of certain of our patents in the Delaware proceeding and judgment has been entered as described in the immediately preceding risk factor and in further detail under Part I, Item 3. “Legal Proceedings”, the IPR process is independent and could result in the narrowing or invalidation of some or all of the asserted claims, which could impair or eliminate our ability to enforce the judgment, collect damages or obtain other relief. While IPRs are a common feature of the U.S. patent system, we believe that our patents are valid and enforceable. We intend to actively defend our intellectual property rights, but the outcome of any administrative proceeding cannot be predicted with certainty**.**
Current report
For the year ended December 31, 2025, two suppliers represented 55% and 36% of the Company’s purchases. For the year ended December 31, 2024, two suppliers represented 51% and 35% of the Company’s purchases. At December 31, 2025 and 2024, 63% and 68% of the Company’s accounts payable and accrued expenses related to two vendors, respectively. The Company believes there are numerous other suppliers that could be substituted should a supplier become unavailable or non-competitive.

Trading activity for our common stock has varied, and, at times, been limited.
Current report
Our indemnification obligations to directors and officers could be costly to us and may discourage lawsuits against them, potentially limiting stockholder rights and remedies.
Current report
For these reasons, penny stocks may have a limited market and, consequently, limited liquidity. We can give no assurance at what time, if ever, our common stock may be classified as a “penny stock” in the future.
Current report
Our Chief Executive Officer has the ability to significantly influence all matters submitted to our stockholders for approval.
Current report
As of March 31, 2026, our Chief Executive Officer, Richard MacPherson, beneficially owned approximately 11.94% of our outstanding shares of common stock. As a result, while we do not expect to be a “controlled company” within the meaning of the corporate governance rules of the NYSE American, Mr. MacPherson is able to significantly influence all matters submitted to our stockholders for approval, as well as our management and affairs. For example, Mr. MacPherson would significantly influence the election of directors and the approval of any merger, consolidation or sale of all or substantially all of our assets. This concentration of voting power could delay or prevent an acquisition of the Company on terms that other stockholders may desire.
Current report
Our Certificate of Incorporation, Bylaws and the DGCL contain provisions that could have the effect of rendering more difficult, delaying, or preventing an acquisition deemed undesirable by our Board of Directors and therefore depressing the trading price of our common stock. These provisions also could make it difficult for stockholders to take certain actions, including electing directors who are not nominated by the current members of our Board of Directors or taking other corporate actions, including effecting changes in our management. Among other things, our Certificate of Incorporation and Bylaws include provisions regarding:
Current report
If we fail to comply with the standards for continued listing on the NYSE American, this could negatively impact the price of our common stock and your ability to sell your shares of common stock.
Current report
Even though we effected the 1-for-5 reverse stock split of our common stock, we cannot assure you that the market price of our common stock will remain high enough for such reverse stock split to have the intended effect of complying with the NYSE American’s minimum price requirement.
Current report
In connection with the uplist of our common stock to the NYSE American, we effected a 1-for-5 reverse stock split on December 26, 2025 with the primary purpose to allow us to meet the NYSE American’s minimum price requirement. There can be no assurance that the market price of our common stock following such reverse stock split will remain at the level required for compliance with that requirement. In any event, other factors unrelated to the number of shares of our common stock outstanding, such as negative financial or operational results, could adversely affect the market price of our common stock and thus jeopardize our ability to meet or maintain the NYSE American’s minimum price requirement.
Current report
The trading market for our common stock will depend in part on the research and reports that securities or industry analysts publish about us or our business. Securities and industry analysts do not currently, and may never, publish research on our Company. If no securities or industry analysts commence coverage of our Company, the trading price for our common stock would likely be negatively impacted. In the event securities or industry analysts initiate coverage, if one or more of the analysts who covers us downgrades our common stock or publishes inaccurate or unfavorable research about our business, our stock price may decline. If one or more of these analysts ceases coverage of our Company or fails to publish reports on us regularly, demand for our common stock could decrease, which might cause our stock price and trading volume to decline.
Current report
We may be constrained in the manner in which we can proceed against the relevant short seller by principles of freedom of speech, applicable state law or issues of commercial confidentiality. Such a situation could be costly and time-consuming, and could distract our management from growing our business. Even if such allegations are ultimately proven to be groundless, allegations against us could severely impact our business, and any investment in the common stock could be greatly reduced or even rendered worthless.
Current report
The market price of our common stock may be volatile, and in the past companies that have experienced volatility in the market price of their securities have been subject to securities class action litigation. We may be the target of this type of litigation in the future. Securities litigation against us could result in substantial costs and divert our management’s attention from other business concerns, which could seriously harm our business.
Current report
There is no assurance that an investment in our common stock will earn any positive return.
Current report
There is no assurance that an investment in our common stock will earn any positive return. An investment in our common stock involves a high degree of risk and should be undertaken only by investors whose financial resources are sufficient to enable them to assume such risks and who have no need for immediate liquidity in their investment. An investment in our common stock is appropriate only for investors who have the capacity to absorb a loss of some or all of their investment.
Current report
An investment in our common stock, and certain subsequent transactions with respect to our common stock, may result in uncertain or adverse U.S. federal income tax consequences for an investor.
Current report
An investment in our common stock, and certain subsequent transactions with respect to our common stock, may result in uncertain or adverse U.S. federal income tax consequences for an investor. See the section entitled “Material U.S. Federal Income Tax Consequences to U.S. and Non-U.S. Holders” below for a summary of the principal U.S. federal income tax consequences of an investment in our common stock. Each prospective investor is urged to consult with and rely solely upon its own tax advisors with respect to these and other tax consequences when purchasing, holding or disposing of our common stock.
Current report
The reverse stock split could cause our stock price to decline relative to its value before the split and decrease the liquidity of shares of our common stock.
Current report
On December 26, 2025, we effected a 1-for-5 reverse stock split of our issued and outstanding common stock. There is no assurance that such reverse stock split will not cause a decline in the value of our outstanding common stock. The liquidity of the shares of our common stock may be affected adversely by such reverse stock split given the reduced number of shares that are outstanding following such reverse stock split, especially if the market price of our common stock does not increase as a result. Additionally, it is not uncommon for the market price of a company’s common stock to decline in the period following a reverse stock split. If the market price of our common stock declines following the effectuation of our 1-for-5 reverse stock split, the percentage decline may be greater than would occur in the absence of such a reverse stock split. In addition, this reverse stock split may have increased the number of stockholders who own odd lots (less than 100 shares) of our common stock, creating the potential for such stockholders to experience an increase in the cost of selling their shares and greater difficulty effecting such sales.

Possible inability to continue as a going concern.
Previous report
Based on our current cash levels and burn rate, amongst other things, we believe our cash and financial resources may be insufficient to meet our anticipated needs for the next twelve months, which raises substantial doubt about our ability to continue as a going concern within one year from the issuance date of the financial statements included elsewhere in this Annual Report. The financial statements included elsewhere in this Annual Report have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. The financial statements do not include any adjustments relating to the recoverability and classification of asset amounts or the classification of liabilities that might be necessary should we be unable to continue as a going concern within one year after the date the financial statements are issued.
Previous report
In addition to maintaining the revenue stream from our legacy mercury emissions control business, our plans and expectations over the next twelve months to mitigate such financial condition include receiving additional cash inflows from the judgment expected in connection with the $57.1 million jury verdict awarded to us in March 2024, additional licensing revenues and product sales from the other patent litigation recently commenced, and revenues from our entry into the water treatment business. During 2024, we opened two new state of the art laboratories and have added personnel to support our entry into the water business which we believe will lead to a vibrant new revenue stream. In addition, management is exploring additional financing opportunities. While management believes these plans will alleviate substantial doubt, there is no assurance that they will be successfully realized or implemented.
Previous report
The results of the 2024 United States presidential election has created regulatory uncertainty.
Previous report
The outcome of the 2024 U.S. presidential election has introduced significant uncertainty regarding future environmental regulations, particularly those affecting mercury emissions from power plants. The newly inaugurated administration has signaled potential shifts in environmental policy, including possible rollbacks of existing regulations and changes in enforcement priorities. For instance, if the administration weakens or repeals the MATS Rule, such regulatory changes could materially impact our operations. In addition, any weakening, rollback, or delayed implementation of PFAS-related regulations could reduce demand for our water treatment technologies, testing services, or remediation solutions, negatively impacting our growth prospects.

Previous wording
North American coal-fired electricity generating units comprise the basis of the market for our services and products. Regulations mandating or incentivizing the purchase of power from renewable energy sources (e.g., wind, solar, hydroelectric, geothermal) and/or the phasing out of coal-fired power plants could lessen the demand for electricity from such plants and overall reduce the number of coal-fired electricity generating units and the amount of coal burned, thereby decreasing the demand for our services and products which could adversely affect our business. The phasing out of coal-fired plants has already had a negative effect on our results of operations. Continued promulgation of these regulations in North America is affected by, among other things, politics, perceived environmental impact, and public favor.

Previous wording
We operate in highly competitive industries that are characterized by a diverse range of participants, including companies that operate in both the mercury capture and water treatment industries. Our major competitors in the mercury capture and water treatment markets includes companies such as Arq, Inc. (formerly Advanced Emissions Solutions, Inc.), Norit Activated Carbon, Calgon Carbon Corporation, and Nalco Company LLC (also known as Nalco Water, an Ecolab company). Many of our competitors employ larger sales staff and are well established in the market with greater financial and operational resources. Our ability to compete successfully depends in part upon our ability to offer superior technology, including a superior team of technical personnel. If we are unable to maintain our competitive position, we could lose market share to our competitors which is likely to adversely impact our financial results.

We have a patent portfolio relating to mercury removal of 35 granted patents worldwide, consisting of 27 U.S. patents and 8 foreign patents (Canada, Germany and China) with expiration dates ranging from August 2025 to September 2034. While we actively pursue new patents and technological advancements to replace expiring patents, there is no guarantee that future patents will be granted, or that they will be able to provide and/or allow us to maintain the same level of market protection. As a result, we may not be able to successfully protect proprietary aspects of our technology.
Current wording
As of December 31, 2025, our patent portfolio relating to mercury removal included 18 granted patents worldwide, consisting of 13 U.S. patents and 5 foreign patents (Canada, Europe and China), with stated expiration dates ranging from January 2026 to September 2034. Between August and October 2025, 13 U.S. Patents and 2 foreign patents relating to mercury removal expired. The patent data and expiration timelines cited above and elsewhere in this report are based on internal assessments and information currently available through third-party databases, including Google Patent Database. While we believe these sources to be generally reliable, they are subject to inherent data lags, indexing errors or incomplete coverage of foreign jurisdictions. Consequently, the actual status, enforceability or precise expiration dates of certain patents may differ from those stated. While we actively pursue new patents and technological advancements to replace expiring patents, there is no guarantee that future patents will be granted, or that they will be able to provide and/or allow us to maintain the same level of market protection. As a result, we may not be able to successfully protect proprietary aspects of our technology.
Previous wording
With regard to our water treatment technologies, we have to date filed two provisional patent applications in the U.S. relating to water treatment. However, provisional applications do not provide enforceable patent rights unless they are converted into non-provisional applications and successfully granted by the U.S. Patent and Trademark Office. There is no assurance that our pending provisional applications will result in issued patents, or that any patents granted will provide meaningful protection against competitors.
Current wording
With regard to our water treatment technologies, we have to date filed two provisional patent applications in the U.S. relating to water treatment. We have also filed two Patent Cooperation Treaty (“PCT”) applications and one U.S. patent application. However, these applications do not provide enforceable patent rights unless they are successfully granted by the PCT and U.S. Patent and Trademark Office. There is no assurance that our pending applications will result in issued patents, or that any patents granted will provide meaningful protection against competitors.
Previous wording
Patent litigation, like most types of commercial litigation, can be expensive, time-consuming, and unpredictable. Any such litigation may require us to spend a substantial amount of time and money and could distract management from our day-to-day operations. There is no assurance that we will be successful in any such litigation. Moreover, in an infringement proceeding, a court may decide that one or more of our patents are not valid or enforceable, or a court may refuse to stop the other party from using the technology at issue on the grounds that our patents do not cover the technology in question. An adverse result in any litigation could put one or more of our patents at risk of being invalidated, held unenforceable, or interpreted narrowly and could put our patent applications at risk of not issuing.

On March 1, 2024, following a five-day jury trial, a federal jury in the U.S. District Court for the District of Delaware awarded a $57.1 million patent infringement verdict in our favor against a group of defendants. Nevertheless, the ultimate success in this litigation against this group of defendants still remains uncertain due to other possible factors including, but not limited to, the results of any post-trial motions and applications, appeals and any collectability issues.
Current wording
On March 1, 2024, following a five-day jury trial, a federal jury in the U.S. District Court for the District of Delaware (the “Court”) awarded a $57.1 million patent infringement verdict in our favor against a group of defendants (the “CERT defendants”). Nevertheless, the ultimate success in this litigation against this group of defendants still remains uncertain due to other possible factors, including, but not limited to, the results of any post-trial motions and applications, appeals and any collectability issues. Following the trial, the Court entered non-final judgments on the verdict against the defendants and the parties submitted post-trial motions relating to the jury trial. The defendants also asserted that the Company’s claims were barred due to their defense that they had an implied license to the asserted patents. A bench trial was held on such issue. On June 10, 2025, the Court ruled that the CERT defendants failed to prove that they had such an implied license and denied their motion to alter or amend the non-final judgment. On September 25, 2025, the Court issued a Memorandum Opinion and Order denying the CERT defendants’ post-trial motion that they should not be held liable as a matter of law for induced infringement, contributory infringement or willful infringement, and on November 20, 2025, the Court issued a Memorandum Opinion and Order denying the CERT defendants’ post-trial motion for a new trial on the issues of induced infringement, contributory infringement, willful infringement and damages. Thereafter, on December 17, 2025, the Court issued a memorandum order granting the Company’s request for pre- and post-judgment interest, and denying the Company’s request for enhanced damages. Following resolution of all post-trial motions, the Court issued the final judgment in favor of the Company on December 29, 2025 in the total amount of $78,397,157, which amount includes pre-judgment interest.

Previous wording
Our customers are concentrated, so the loss of one or more key customers or a material reduction in business performed for them could cause us to experience a decline in net sales, which could adversely affect our financial results. In addition, there can be no assurance that such customers will not experience financial difficulties or other problems which could delay such customers in paying for product and services on a timely basis or at all. Any problems with such customers can be expected to have an adverse impact on our results of operations and financial condition.
Current wording
For the year ended December 31, 2025, three customers represented 29%, 11%, and 9% of the Company’s revenues, and for the year ended December 31, 2024, three customers represented 32%, 13%, and 10% of the Company’s revenues. At December 31, 2025, two customers represented 51%, and14% of the Company’s accounts receivable, and at December 31, 2024, three customers represented 32%, 26% and 9% of the Company’s accounts receivable.

We are subject to the requirements of the Exchange Act, including the requirements of the Sarbanes-Oxley Act of 2002. The requirements of these rules and regulations have increased in recent years, causing an increase in legal and financial compliance costs, and make some activities more difficult, time-consuming, or costly and may also place undue strain on our personnel, systems, and resources. Such rules and regulations require, among other things, that we maintain effective disclosure controls and procedures and internal control over financial reporting. This can be difficult to do. In this regard, our management concluded our internal control over financial reporting was not effective as of December 31, 2024. While certain remedial actions have been completed, we continue to actively plan for and implement additional control procedures to improve our overall control environment and expect these efforts to continue throughout the rest of 2025 and beyond. As a result of this and similar activities, management’s attention may be diverted from other business concerns, which could have a material adverse effect on our business, financial condition, and results of operations. Further, investors could lose confidence in our financial reports, and our stock price may be adversely affected, if our internal controls over financial reporting continue to be found not to be effective by management or if we make disclosure of existing or potential significant deficiencies or material weaknesses in those controls in the future. Relatedly, if we fail to remediate any such material weakness in the future, we may not be able to accurately report our financial condition or results of operations.

On March 28, 2025, our board of directors, along with our audit committee and with management and, following dialogue with our auditors, concluded that our previously issued financial statements for the periods ended December 31, 2023 and 2022 included in the Company’s Annual Reports of Form 10-K, March 31, 2024, June 30, 2024, and September 30, 2024, March 31, 2023, June 30, 2023, and September 30, 2023, included in the Company’s Quarterly Reports of Form 10-Q, should no longer be relied upon as a result of the change in accounting for a certain license agreement. We concluded that the Company should have recognized the entire proceeds receivable pursuant to the agreement as revenue during the year ended December 31, 2022. The Company should also have recognized the financing component of the licensing agreement during the fiscal years ended December 31, 2023 and 2024. Such restatement could cause uncertain sentiment in the investment community.

Previous wording
Our business relies heavily on environmental regulations governing emissions from coal-fired power plants and regulations related to water treatment. In the United States, the Mercury and Air Toxics Standards (MATS) rule, issued by the U.S. Environmental Protection Agency (EPA) in 2011, is intended to reduce air emissions of heavy metals, including mercury (“Hg”), from all major U.S. power plants burning coal or oil, which are the leading source of non-natural mercury emissions in the U.S. Potable water treatment is regulated primarily by the EPA under the Safe Drinking Water Act (“SDWA”), which establishes standards to ensure that water is safe for human consumption. In April 2024, the EPA issued the first-ever national, enforceable drinking water standard to protect communities from exposure to harmful per-and polyfluoroalkyl substances (“PFAS”), also known as “forever chemicals”. The Rule sets limits for five individual PFAS: PFOA, PFOS, PFNA, PFHxS, and HFPO-DA (known as GenX Chemicals). Any changes, rollbacks or delays in these regulations could significantly impact the Company’s financial performance and growth prospects.

Any changes, rollbacks or delays in these regulations could significantly impact the Company’s financial performance and growth prospects. In this regard, on May 14, 2025, the EPA under the new Trump Administration announced the agency will keep the regulations for PFOA and PFOS, but also announced its intent to extend the PFOA and PFOS MCL compliance deadlines to 2031 and establish a federal exemption framework. Additionally, the EPA announced its intent to rescind the regulations and reconsider the regulatory determinations for PFHxS, PFNA, HFPO-DA, and the Hazard Index mixture of these three PFAS plus PFBS to ensure the determinations and any resulting drinking water regulation follow the SDWA process.

Since being enacted, the MATS Rule has been subject to legal challenges which may continue.
Current wording
Since being enacted, the MATS Rule has been subject to legal challenges and modifications which may continue.
Previous wording
Since being enacted in 2011, the MATS regulation has been subject to legal challenge. In June 2015, the U.S. Supreme Court, inMichigan v. EPA, held that the EPA unreasonably failed to consider costs in determining whether it is "appropriate and necessary" to regulate hazardous air pollutants, including mercury, from power plants, but left the rule in place. In April 2016, the EPA issued a supplemental finding in response to theMichigan decision and found that, after a consideration of costs, it remained appropriate and necessary to regulate such emissions from coal- and oil-fired power plants. In May 2020, the EPA, then under the first Trump Administration, reversed the determination, finding that, after weighing the costs of compliance against certain benefits of the regulation, the 2016 supplemental finding was erroneous but left the MATS rule in place. Upon taking office, the Biden Administration in January 2021 directed the EPA to review the previous Administration’s actions on various environmental matters including the withdrawal of the May 2020 “appropriate and necessary” determination, for conformity with Biden Administration environmental policy. On February 9, 2022, the EPA proposed to revoke the May 2020 finding and reaffirm the EPA’s 2016 finding. On February 15, 2023, the EPA reaffirmed that it remains appropriate and necessary to regulate hazardous air pollutants, including mercury, from power plants after considering cost, and revoked the May 2020 finding. On April 3, 2023, the EPA issued a proposal to strengthen and update MATS. The newly inaugurated second Trump Administration has indicated potential shifts in environmental policies, which may include revisiting existing regulations such as MATS. In this regard, on March 12, 2025, the newly appointed EPA administrator under the Trump Administration announced plans to roll back dozens of environmental regulations including the reconsideration of the MATS regulation.
Current wording
Since being enacted in 2011, the MATS regulation has been subject to legal challenge and modifications. In June 2015, the U.S. Supreme Court, inMichigan v. EPA, held that the EPA unreasonably failed to consider costs in determining whether it is “appropriate and necessary” to regulate hazardous air pollutants, including mercury, from power plants, but left the rule in place. In April 2016, the EPA issued a supplemental finding in response to theMichigan decision and found that, after a consideration of costs, it remained appropriate and necessary to regulate such emissions from coal- and oil-fired power plants. In May 2020, the EPA, then under the first Trump Administration, reversed the determination, finding that, after weighing the costs of compliance against certain benefits of the regulation, the 2016 supplemental finding was erroneous, but left the MATS rule in place. Upon taking office, the Biden Administration in January 2021 directed the EPA to review the previous Administration’s actions on various environmental matters, including the withdrawal of the May 2020 “appropriate and necessary” determination, for conformity with the Biden Administration’s environmental policy. On February 9, 2022, the EPA proposed to revoke the May 2020 finding and reaffirm the EPA’s 2016 finding. On February 15, 2023, the EPA reaffirmed that it remains appropriate and necessary to regulate hazardous air pollutants, including mercury, from power plants after considering cost, and revoked the May 2020 finding. In April 2023, the EPA issued a proposal to strengthen and update MATS. Such proposal was finalized and published in May 2024, with an effective date of July 8, 2024, which, among other things, strengthens and updates MATS for coal-fired power plants and tightens the emission standard for mercury for existing lignite-fired power plants to a level that is aligned with the mercury standard that other coal-fired power plants have been achieving under MATS. On March 12, 2025, the newly appointed EPA administrator under the Trump Administration announced plans to roll back dozens of environmental regulations, including the reconsideration of the MATS regulation. On April 8, 2025, President Trump signed a Proclamation exempting certain stationary sources, identified in Annex 1 of the Proclamation, from compliance with the 2024 updated MATS Rule. As set out in the Proclamation, the President’s exemption lasts for a period of two years beyond the updated Rule’s compliance date (i.e., for the period beginning July 8, 2027 and concluding July 8, 2029). During the two-year period, these stationary sources identified in Annex 1 are subject to the compliance obligations that they are currently subject to under MATS as the MATS Rule existed prior to the 2024 update. Annex 1 identifies 47 plant owners and over 60 power plants provided such exemption. In June 2025, the EPA proposed to repeal certain amendments finalized in 2024 to the MATS Rule and return compliance obl…

Our common stock is currently traded in Canada on the Toronto Stock Exchange (“TSX”) under the symbol “BCHT” and is quoted in the United States on the OTCQB operated by OTC Markets Group Inc. under the symbol “BCHT”. Historically, the trading volume for our common stock has been limited. Accordingly, investors may find it more difficult to buy and sell our shares. These factors may have an adverse impact on the trading and price of our common stock.
Current wording
Our common stock is currently traded in Canada on the TSX under the symbol “BCHT” and prior to February 26, 2026 was quoted in the United States on the OTCQB operated by OTC Markets Group Inc. under the symbol “BCHT”. Effective February 26, 2026, our common stock became listed and began trading on the NYSE American under the symbol “BCHT”, at which point our common stock ceased being traded on the OTCQB. Historically, the trading volume for our common stock has varied and, at times, been limited. Accordingly, if we are not able to maintain the listing of our shares of common stock on the NYSE American or the TSX and our common stock becomes quoted on the OTCQB again, investors may find it more difficult to buy and sell our shares. These factors may have an adverse impact on the trading and price of our common stock.
Previous wording
Any of these factors, as well as broader market and industry factors, may result in large and sudden changes in the trading volume of our common stock and could seriously harm the market price of our common stock, regardless of our operating performance. This may prevent you from being able to sell your shares at or above the price you paid for your shares of our common stock, if at all. In addition, following periods of volatility in the market price of a company’s securities, stockholders often institute securities class action litigation against that company. Our involvement in any class action suit or other legal proceeding could divert our senior management’s attention and could adversely affect our business, financial condition, results of operations, and prospects.

Sales of substantial amounts of shares or the perception that such sales could occur may adversely affect the prevailing market price for our shares. We may issue additional shares in subsequent public offerings or private placements to make new investments or for other purposes. We are not required to offer any such shares to existing shareholders on a preemptive basis. Therefore, it may not be possible for existing shareholders to participate in such future share issuances, which may dilute the existing shareholders’ interests in us.

We may need additional capital in the future, which may not be available on acceptable terms or at all, to among other things, continue investing in our business, pursue acquisitions and other strategic transactions. Future financings may involve the issuance of debt, equity, and/or securities convertible into or exercisable or exchangeable for our equity securities.

If we are able to consummate such financings, the trading price of our common stock could be adversely affected and/or the terms of such financings may adversely affect the interests of our existing stockholders. Any failure to obtain additional working capital, if and when required, could have a material adverse effect on our business and financial condition and may result in a decline in our stock price.

Our articles of incorporation provide that we possess and may exercise all powers of indemnification of our officers, directors, employees, agents, and other persons and our bylaws also require us to indemnify our officers and directors as permitted under the provisions of the Delaware General Corporate Law. The foregoing indemnification obligations could result in our incurring substantial expenditures to cover the cost of settlement or damage awards against directors and officers. These provisions and resultant costs may also discourage us from bringing a lawsuit against directors, officers, and employees for breaches of their fiduciary duties, and may similarly discourage the filing of derivative litigation by our stockholders against our directors, officers, and employees even though such actions, if successful, might otherwise benefit the Company and stockholders.

Our Certificate of Incorporation provides that we possess and may exercise all powers of indemnification of our officers, directors, employees, agents, and other persons and our second amended and restated by-laws (“Bylaws”) also require us to indemnify our officers and directors as permitted under the provisions of the General Corporate Law of the State of Delaware (the “DGCL”). In addition, we have entered into agreements to indemnify our directors and executive officers. These agreements, among other things, require us to indemnify these individuals for certain expenses (including attorneys’ fees), judgments, fines, and settlement amounts reasonably incurred by such person in any action or proceeding, including any action by or in our right, on account of any services undertaken by such person on behalf of our Company or that person’s status as a member of our Board of Directors to the maximum extent allowed under Delaware law.

Our common stock is currently characterized as a “penny stock” under SEC rules. It may be more difficult to resell securities classified as “penny stock.”
Current wording
If our common stock becomes characterized as a “penny stock” again under SEC rules, it may be more difficult to resell our common stock.
Previous wording
Our common stock is currently characterized as a “penny stock” under applicable SEC rules (generally defined as non-exchange traded stock with a per-share price below $5.00). These rules impose additional sales practice requirements on broker-dealers that recommend the purchase or sale of penny stocks to persons other than those who qualify as “established customers” or “accredited investors.” For example, broker-dealers must determine the appropriateness for non-qualifying persons of investments in penny stocks. Broker-dealers must also provide, prior to a transaction in a penny stock not otherwise exempt from the rules, a standardized risk disclosure document that provides information about penny stocks and the risks in the penny stock market. The broker-dealer also must provide the customer with current bid and offer quotations for the penny stock, disclose the compensation of the broker-dealer and its salesperson in the transaction, furnish monthly account statements showing the market value of each penny stock held in the customer’s account, provide a special written determination that the penny stock is a suitable investment for the purchaser, and receive the purchaser’s written agreement to the transaction.
Current wording
Prior to the recent listing of our common stock on the NYSE American, our common stock was considered a “penny stock” under applicable SEC rules (generally defined as non-exchange traded stock with a per-share price below $5.00). While we do not expect our common stock to be considered a “penny stock” following our listing, if we are later deemed a “penny stock”, certain rules impose additional sales practice requirements on broker-dealers that recommend the purchase or sale of penny stocks to persons other than those who qualify as “established customers” or “accredited investors.” For example, broker-dealers must determine the appropriateness for non-qualifying persons of investments in penny stocks.

Many of the shares of our common stock presently held by management and others are “restricted securities” as that term is defined in Rule 144, promulgated under the United States Securities Act of 1933, as amended. Under Rule 144, a person (or persons whose shares are aggregated) who has satisfied a certain holding period, may, under certain circumstances, sell such shares or a portion of such shares. Such holding periods have already been satisfied in many instances. Therefore, actual sales or the prospect of sales of such shares under Rule 144 in the future may depress the price of our common stock.
