GERON CORP

Previous wording

As a company, we have limited prior experience in selling and marketing or commercializing an approved drug product in the U.S., and we have no experience selling, marketing or commercializing an approved drug outside of the U.S. The success of our commercialization efforts is subject to, among other things, managing our internal sales, marketing, and distribution capabilities and our ability to navigate the significant expenses and risks involved with the management of such capabilities. For example, RYTELO sales trends have been and may continue to be variable. Net product revenue was approximately $49.0 million in the second quarter of 2025, $39.4 million in the first quarter of 2025, and $47.5 million in the fourth quarter of 2024. Our priority is to drive new patient starts across the breadth of the eligible patient population in RYTELO’s approved indication in the U.S. Our strategy to drive sales growth in the U.S. is currently focused on three key areas: investing additional resources to increase brand awareness, including increasing the size of our commercial and medical field forces; refining our marketing and medical efforts to enhance prescribing clarity and confidence with the approved use of RYTELO; and implementing programs to expand key opinion leader support and advocacy. However, this strategy and our ongoing commercialization efforts may not achieve meaningful sales growth, which may require us to, among other things, further adjust or amend our commercialization strategy and plans and incur significant expenses, and there can be no assurance that we will be able to grow RYTELO net product revenues in future periods. In particular, our strategy may not drive new patient starts across the breadth of the eligible patient population in RYTELO's approved indication in a timely manner or at all, or the duration of therapy could be shorter than we expect, each of which would limit RYTELO's growth potential and could preclude or delay our ability to generate meaningful revenue from product sales and to achieve profitability. Further, given our limited historical experience commercializing drug products, we do not have a track record of successfully executing a commercial launch. If we are unsuccessful in accomplishing our objectives from our commercialization efforts and strategy, or they are not executed as planned, we may not be able to generate meaningful revenues from the commercialization of RYTELO in lower-risk MDS, we may require significant additional capital and financial resources, we may not become profitable, and we may not be able to compete against more established companies in our industry. Any of these outcomes would severely and adversely affect our financial results, business and business prospects, and might cause us to cease operations.

In the second quarter of 2025, we increased the size of our sales force by 20% and doubled the size of our medical affairs team. However, our strategy to drive sales growth and our ongoing commercialization efforts has not to date achieved and may not in the future achieve meaningful sales growth, which may require us to, among other things, further adjust or amend our commercialization strategy and plans and incur significant expenses, and there can be no assurance that we will be able to grow RYTELO net product revenues in future periods.

Further, given our limited experience in marketing and selling RYTELO, we continue to evaluate and adapt our strategy in response to experience in the marketplace and have determined to expand our field sales force and medical support liaisons to support our U.S. commercialization efforts. However, we may determine that we need further changes in the future that require additional hiring to further expand our field sales force and medical support liaisons to adequately support the commercialization of RYTELO in the U.S., which could further increase our costs. With respect to the EU or any other regions outside the U.S. where we might seek marketing authorization in the future for RYTELO, we plan to enter into arrangements with other third parties to utilize their local marketing and distribution capabilities, but we may be unable to enter into such arrangements on favorable terms, if at all. If potential future partners do not commit sufficient resources to commercialize RYTELO, we may be unable to generate sufficient product revenue to sustain our business. In any event, if we are unable to establish and maintain adequate sales and marketing capabilities for RYTELO, whether on our own or through contractual arrangements, collaborations or other arrangements, our results of operations may be negatively impacted. Any of the foregoing would negatively impact our business and business prospects, severely and adversely affect our financial results, and might cause us to cease operations.

In addition, government authorities and other third-party payors in the U.S. and other jurisdictions are developing increasingly sophisticated methods of controlling healthcare costs, such as by limiting coverage and the amount of reimbursement for particular medications. Increasingly, third-party payors are requiring that drug companies provide them with predetermined discounts from list prices as a condition of coverage, are using restrictive formularies and preferred drug lists to leverage greater discounts in competitive classes, and are challenging the prices charged for medical products. The Inflation Reduction Act of 2022 includes several provisions to lower prescription drug costs for people with Medicare and reduce drug spending by the federal government, which may ultimately have a negative effect on the pricing for RYTELO. However, the Medicare Drug Pricing Negotiation Program provisions of the law are currently subject to legal challenges. Further, no uniform policy requirement for coverage and reimbursement for drug products exists among third-party payors in the U.S. As a result, the coverage determination process is often a time-consuming and costly process that will require us to provide scientific and clinical support for the use of RYTELO to each payor separately, with no assurance that coverage and adequate reimbursement will be applied consistently or obtained in the first instance.

Further, on July 16, 2025, the Centers for Medicare & Medicaid Services issued the CY 2026 Medicare Physician Fee Schedule proposed rule, which if finalized, would, among other things, restrict whether certain fees should be considered bona fide service fees, increase bona fide service fee documentation requirements, define “bundled arrangement,” require “unbundling” of both contingent and non-contingent discounts and include sales of Part B units at the Maximum Fair Price in average sales price calculations. These changes, if finalized, could lower reimbursement for Medicare Part B utilization and require manufacturers to comply with new, uncertain or complex reporting obligations and drug pricing documentation practices.

Previous wording

Although we have received a permanent and product-specific J-Code (J0870) for RYTELO which became effective on January 1, 2025, there may also be significant delays in obtaining coverage and reimbursement for newly approved drugs, and coverage may be more limited than the purposes for which the drug is approved by the FDA or similar international regulatory authorities. Coverage and reimbursement may impact the demand for, or the price of RYTELO, and reimbursement policies in the U.S., the EU, and other jurisdictions may evolve which may adversely impact our ability to successfully commercialize RYTELO. Even if favorable coverage and reimbursement status is attained for one or more products for which we receive regulatory approval, less favorable coverage policies and reimbursement rates may be implemented in the future. If coverage and reimbursement are not available or reimbursement is available only to limited levels, we may not be able to successfully commercialize RYTELO, which would negatively impact our business and business prospects.

RYTELO may not achieve market acceptance for lower-risk MDS or any other indication that might be approved in the future, or achieve the potential U.S. or international revenue we believe may be possible for lower-risk MDS, since hospitals, physicians, patients or the medical community in general may decide not to accept and utilize RYTELO at the rate we expector may not use RYTELO across the breadth of eligible patient segments. For example, new patient starts in the U.S. through the end of the first quarter of 2025 have been primarily in the third-line setting. While our current priority is to drive new patient starts across the breadth of eligible patient segments in RYTELO's approved indication, we may be unable to do so in a timely manner or at all, which would limit RYTELO's growth potential and which could delay or preclude our ability to generate meaningful revenue from product sales and to achieve profitability. Furthermore, RYTELO competes with a number of conventional and widely accepted drugs and therapies manufactured and marketed by major pharmaceutical companies. The degree of market acceptance of RYTELO depends on a number of factors, including:

Our regulatory approval for RYTELO in lower-risk MDS in the U.S. is subject to non-clinical, clinical and manufacturing post-marketing requirements and commitments, including the requirement of continuing to assess long-term safety of RYTELO (imetelstat) in the IMerge trial and a clinical trial to evaluate alternative dosing regimens in lower-risk MDS, with timelines for completion and reporting established by the FDA. In the EU, our regulatory approval for RYTELO in certain patients with TD anemia due to lower-risk MDS is subject to our commitment to submit the results from certain ongoing non-clinical and clinical studies required by the FDA, including the assessment of the long-term safety of RYTELO in the IMerge trial, as well as results from an ongoing substudy within the IMerge trial and the completion of certain quality-related activities and study. In addition, RYTELO and the manufacturing processes and facilities, post-approval clinical data, labeling, advertising and promotional activities related to RYTELO will be subject to continual requirements of, and review by, the FDA and comparable regulatory authorities. These requirements include submissions of safety and other post-marketing information and reports, compliance with good pharmacovigilance practices, registration requirements, current Good Manufacturing Practice, or cGMP, requirements relating to quality control, quality assurance and corresponding maintenance of records and documents, and requirements regarding promotional interactions with healthcare professionals.

Previous wording

In April 2025, the U.S. government imposed a 10% baseline global tariff, while suspending the imposition of higher “reciprocal” tariffs on numerous other territories until August 2025. The U.S. government has also specifically stated that the pharmaceutical industry will be subject to industry-specific tariffs and has initiated a related investigation into the national security effects of imported pharmaceuticals and their ingredients. As such, we currently expect that the current pharmaceutical exemption will be short-lived and that such industry-specific pharmaceutical tariffs will ultimately be imposed by the U.S. government. Although a significant portion of our supply chain for imetelstat is currently based in the U.S., the active pharmaceutical ingredient, or API, for imetelstat is manufactured in South Korea and our 47mg vial of RYTELO drug product is currently manufactured in Italy. In addition, in the future we may choose to utilize other contract manufacturers for different presentations of imetelstat and source materials for our supply chain from other international jurisdictions. Accordingly, such global or industry-specific tariffs, or the renegotiation of current international trade agreements, or other trade restrictions could result in additional costs on our business, including generally increasing our manufacturing costs, and may decrease our gross margins and increase our supply chain complexity. Moreover, other governments have imposed and may continue to impose retaliatory tariffs, trade restrictions or trade barriers impacting RYTELO, which could impose additional costs and complexity on our business, including with respect to our planned commercialization of RYTELO in select EU markets in 2026 or restrict our ability to sell RYTELO in the EU or in other international markets where we may obtain approval of RYTELO.

Current wording

The ongoing trade tensions between the U.S. and other jurisdictions have resulted in multiple rounds of tariffs and anticipated tariffs affecting pharmaceuticals and pharmaceutical ingredients, including finished drug products, manufacturing equipment, and related supplies. In April 2025, the U.S. government imposed a 10% baseline global tariff and in August 2025, the U.S. imposed higher “reciprocal” tariffs on numerous other territories, including EU Member States and South Korea, with the potential for future increases or revisions. The Bureau of Industry and Security, U.S. Department of Commerce, has initiated an investigation to determine whether pharmaceutical ingredients, including finished drug product, manufactured outside the U.S. pose a national security risk and should be subject to additional tariffs. Unlike consumer goods, pharmaceuticals face unique regulatory constraints that make rapid supply chain adjustments particularly difficult and costly. Although a significant portion of our supply chain for imetelstat is currently based in the U.S., the active pharmaceutical ingredient, or API, for imetelstat is manufactured in South Korea and our 47mg vial of RYTELO drug product is currently manufactured in Italy.

In addition, because remaining patients in ongoing clinical trials continue to receive imetelstat, additional or more severe toxicities or safety issues may be observed, and the benefit-risk profile of imetelstat will continue to be assessed, including the risk of hepatotoxicity, severe cytopenias, fatal bleeding with or without any associated thrombocytopenia, patient injury or death. New data relating to imetelstat, including from adverse event reports and our post-marketing requirements in the United States, and from ongoing clinical trials of imetelstat, may result in changes to the product label and may adversely affect sales, or result in withdrawal of imetelstat from the market. The FDA and regulatory authorities in other jurisdictions may also consider the new data in reviewing our marketing applications for additional indications and/or in other jurisdictions, or impose post-approval requirements. If any of these actions were to occur, it could result in significant expense and delay or limit our ability to generate sales revenues.

Furthermore, non-clinical and clinical data are often susceptible to varying interpretations and analyses. In some instances, there can be significant variability between different clinical trials of imetelstat due to numerous factors, including changes in trial procedures set forth in trial protocols, differences in the size and type of patient populations, and changes in and adherence to the dosing regimens. For example, although the statistical analyses comparing IMbark data to closely matched real world data, or RWD, published in the September 2021 issue of the Annals of Hematology, suggest potentially favorable overall survival in relapsed/refractory MF patients treated with imetelstat, compared to BAT using closely matched patients’ RWD, such comparative analyses between RWD and our clinical trial data have several limitations. For instance, the analyses create a balance between treatment groups with respect to commonly available covariates, but do not take into account the unmeasured and unknown covariates that may affect the outcomes of the analyses. Potential biases are introduced by factors which include, for example, the selection of the patients included in the analyses, misclassification in the matching process, the small sample size, and estimates that may not represent the outcomes for the true treated patient population. Failure to achieve results supporting a positive benefit-risk profile in current or potential future imetelstat clinical trials would interrupt, further delay, or halt, any development of imetelstat, which would have a severe adverse effect on our results of operations, financial condition and ability to raise additional capital, if needed, business and business prospects.

Top-line results and data may differ from future results of the same study, or different conclusions or considerations may qualify such results, once additional data have been received and fully evaluated. Moreover, as remaining patients in IMerge Phase 3 continue to be treated and followed under the extension phase of the trial and longer-term outcomes are assessed, these additional and more mature data may alter the benefit-risk profile of imetelstat in an adverse manner, including with respect to overall survival. Material adverse differences in future results, compared to preliminary, interim or top-line data, could severely and adversely affect our financial results, business and business prospects, including the commercialization of RYTELO, and might cause us to cease operations.

Successful drug development and commercialization requires significant amounts of capital. As of June 30, 2025, we had approximately $432.6 million in cash, cash equivalents, restricted cash and marketable securities. While we believe that, based on our current operating plans and assumptions, our existing cash, cash equivalents, and marketable securities, together with anticipated net revenues from sales of RYTELO, will be sufficient to fund our projected operating requirements for the foreseeable future, if we do not generate net revenues from commercial sales of RYTELO at the levels we anticipate, if we experience unforeseen events or choose to make other investments in our business, or our assumptions regarding our projected operating expenses are otherwise incorrect, we may require additional funding, which could include a combination of public or private equity offerings, debt financings (including additional tranches under the Pharmakon Loan Agreement, if available), collaborations, strategic alliances, licensing arrangements or marketing and distribution arrangements, which may not be possible. For example, changes in our operations, such as increased development, manufacturing and clinical trial expenses, or our undertaking of additional programs, business activities, or entry into strategic transactions, including potential future acquisitions of products, technologies or businesses, may cause our operating expenses to increase, perhaps significantly, which could require us to raise additional funding. If adequate funds are not available to us when we need them, our RYTELO commercialization efforts may be adversely affected and we may be unable to pursue further development of imetelstat, which would severely harm our business and we might cease operations.

In the event we need to raise additional capital to fund our business, including pursuant to the 2023 Sales Agreement with B. Riley Securities, Inc., the Tranche B Loan and the Tranche C Loan under the Pharmakon Loan Agreement, which are subject to certain funding conditions; capital lease transactions or other financing sources, such additional capital may not be available on acceptable terms, or at all. We may be unable to raise equity capital, or may be forced to do so at a stock price or on other terms that could result in substantial dilution of ownership for our stockholders. The receptivity of the public and private debt and equity markets to proposed financings has been substantially affected by uncertainty in the general economic, market and political climate due to the effects of macroeconomic or other global conditions, such as inflation, fluctuations in interest rates, prospects of a recession, government shutdowns, further changes in tariffs and other trade restrictions, bank failures and other disruptions to financial systems, civil or political unrest, military conflicts, pandemics or other health crises and supply chain and resource issues, and may in the future be affected by other factors which are unpredictable and over which we have no control. These effects have increased market volatility and could result in a significant long-term disruption of global financial markets, which could reduce or eliminate our ability to raise additional funds through financings, and could negatively impact the terms upon which we may raise those funds. Similarly, these macroeconomic conditions have created extreme volatility and disruption in the capital markets and is expected to have further global economic consequences. If the equity and credit markets deteriorate, including as a result of macroeconomic or other global conditions, such as further changes in tariffs and other trade restrictions and uncertainty around further escalation of trade tensions and renegotiation of existing international trade agreements, inflation, fluctuations in interest rates, prospects of a recession, government shutdowns, bank failures and other disruptions to financial systems, civil or political unrest, military conflicts, pandemics or other health crises and supply chain and resource issues, it may make any necessary debt or equity financing more difficult to obtain in a timely manner or on favorable terms, more costly or more dilutive. If we are unable to effectively commercialize RYTELO, or raise additional capital, if needed, or establish alternative collaborative arrangements with third-party collaborative partners for RYTELO when needed, the development and commercialization of RYTELO may be further delayed, altered or abandoned, which might cause us to cease operations.

If the equity and credit markets deteriorate, including as a result of macroeconomic or other global conditions, such as further changes in tariffs and other trade restrictions and uncertainty around further escalation of trade tensions and renegotiation of existing international trade agreements, inflation, fluctuations in interest rates, prospects of a recession, government shutdowns, bank failures and other disruptions to financial systems, civil or political unrest, military conflicts, pandemics or other health crises and supply chain and resource issues, it may make any necessary debt or equity financing more difficult to obtain in a timely manner or on favorable terms, more costly or more dilutive. If we are unable to effectively commercialize RYTELO, or raise additional capital, if needed, or establish alternative collaborative arrangements with third-party collaborative partners for RYTELO when needed, the development and commercialization of RYTELO may be further delayed, altered or abandoned, which might cause us to cease operations.

The Royalty Pharma Agreement contains covenants that impose on us certain obligations with respect to royalty payments, diligence, reporting, indemnification and includes restrictions on intellectual property transfers and out-licenses, and certain other actions. The Royalty Pharma Agreement also limits our ability to create or incur liens or dispose of certain assets related to imetelstat. We have no rights to repurchase the revenue interests in RYTELO sold to Royalty Pharma (other than in connection with a change of control event), thereby limiting our ability to eliminate future applicability of the covenants contained in the Royalty Pharma Agreement. Compliance with these covenants may limit our flexibility in operating our business and our ability to take actions that might otherwise be advantageous to us and our stockholders.

Current wording

The Royalty Pharma Agreement contains covenants that impose on us certain obligations with respect to royalty payments, diligence, reporting, indemnification and includes restrictions on intellectual property transfers and out-licenses, and certain other actions. For example, we are obligated to make royalty payments each quarter based on U.S. net sales of RYTELO at the royalty rates set forth in the Royalty Pharma Agreement, until the date when the aggregate Royalty Payments equal or exceed 1.65 times the Purchase Price, if this occurs by June 30, 2031. However, in the event we are unable to repay our obligation to Royalty Pharma before June 30, 2031, we will be required to make royalty payments equal to or exceeding 2.0 times the Purchase Price thereafter, which may negatively impact our business, financial condition and results of operations. The Royalty Pharma Agreement also limits our ability to create or incur liens or dispose of certain assets related to imetelstat. We have no rights to repurchase the revenue interests in RYTELO sold to Royalty Pharma (other than in connection with a change of control event), thereby limiting our ability to eliminate future applicability of the covenants contained in the Royalty Pharma Agreement.

Also, there are regulations for the listing of patents in the Approved Drug Products with Therapeutic Equivalence Evaluations, or the Orange Book. Some of our patents have been listed in the Orange Book. Manufacturers of generic drugs may challenge the listing. If an appropriate patent covering RYTELO is not listed in the Orange Book or is subsequently removed from the Orange Book, a manufacturer of generic drugs would not be required to provide advance notice to us of any abbreviated NDA filed with the FDA to obtain permission to sell a generic version of RYTELO. Any of the foregoing could harm our competitive position, business, financial condition, results of operations and prospects.

Over the past few years, we have experienced significant changes in executive leadership, and more could occur. For example, on August 6, 2025, we announced the appointment of Harout Semerjian as our President and Chief Executive Officer and a member of our board of directors, effective August 7, 2025. In addition, in November 2024, we appointed a new EVP of Research and Development, and, in September 2024, we appointed a new EVP, Chief Commercial Officer. Changes to company strategy, which can often times occur with the appointment of new executives, can create uncertainty, may negatively impact our ability to execute quickly and effectively, and may ultimately be unsuccessful. In addition, executive leadership transition periods are often difficult as the new executives gain detailed knowledge of our operations, and friction can result from changes in strategy and management style. Management transition inherently causes some loss of institutional knowledge, which can negatively affect strategy and execution. Until we integrate new personnel, and unless they are able to succeed in their positions, we may be unable to successfully manage and grow our business, and our results of operations and financial condition could suffer as a result. In any event, changes in our organization as a result of executive management transition may have a disruptive impact on our ability to implement our strategy and could have a material adverse effect on our financial condition and our business and business prospects.

Securities class action lawsuits and/or derivative lawsuits have often been brought against companies, including biotechnology and biopharmaceutical companies, that experience volatility in the market price of their securities. This risk is especially relevant for us because we often experience significant stock price volatility in connection with our activities. On March 13 and March 14, 2025, we and certain of our current and former officers were named as defendants in two putative securities class action lawsuits filed in the United States District Court for the Northern District of California captioned Dabestani v. Geron Corporation, et al., No. 3:25-cv-02507-CRB and Potvin v. Geron Corporation, et al., No. 3:25-cv-02563-CRB, respectively. Both lawsuits allege violation of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended, and Rule 10b-5 promulgated thereunder in connection with allegedly false and misleading statements concerning the commercial potential of RYTELO. The plaintiffs allege, among other things, that we overstated RYTELO's commercial potential by making materially false and misleading statements and/or concealing material adverse facts concerning RYTELO's commercial potential, including the lack of awareness among healthcare providers for RYTELO, the burden of monitoring requirements in administering the drug, and the impacts of seasonality and existing competition on RYTELO's sales, and that our stock price dropped when we disclosed in our earnings call on February 26, 2025 that we had observed flat revenue trends over the prior few months. The plaintiffs seek damages and interest, and an award of reasonable costs, including attorneys' and experts' fees. On May 29, 2025, the Court consolidated the Dabestani and Potvin cases into one consolidated action captioned In re Geron Corporation Securities Litigation, or the Securities Class Action, and appointed lead plaintiffs and counsel for lead plaintiffs. On June 10, 2025, the Court ordered plaintiffs to file a consolidated amended complaint by August 8, 2025.

It is possible that additional lawsuits might be filed, or allegations might be received from stockholders, with respect to these same matters as alleged in the pending lawsuits or other matters and also naming us and/or our officers and directors as defendants. Such lawsuits and any other related lawsuits are subject to inherent uncertainties, and the actual defense and disposition costs will depend upon many unknown factors. The outcome of the pending lawsuits and any other related lawsuits is necessarily uncertain. We could be forced to expend significant resources and may incur substantial legal fees and costs in the defense of the pending lawsuits and any related or additional lawsuits, and we may not prevail. Monitoring, initiating and defending against legal actions is also time-consuming for our management, is likely to be expensive and may detract from our ability to fully focus our internal resources on our business activities. Given the early stage of these lawsuits and the inherent uncertainly of litigation, we cannot predict how long it may take to resolve the pending lawsuits or the amount of costs we may incur, or the potential outcome or the possible amount of any damages we may be required to pay. A decision adverse to our interests in the pending lawsuits or in similar or related litigation, could result in the payment of substantial damages or settlements, or possibly fines, and, although we maintain liability insurance, we may not be successful in having any such lawsuits dismissed or settled within the limits of our insurance coverage. If any judgement or settlement against us and costs or expenses associated with the pending litigation exceed our insurance coverage or insurance coverage is denied, we may be forced to bear some or all of these costs and expenses directly, which could be substantial and could have a material adverse effect on our business, our stock price, cash flow, results of operations and financial condition.

Although there are currently various mechanisms that may be used to transfer personal data from the EEA and UK to the U.S. in compliance with law, such as the EEA and UK’s standard contractual clauses, the UK’s International Data Transfer Agreement / Addendum, and the EU-U.S. Data Privacy Framework and the UK extension thereto (which allows for transfers to relevant U.S.-based organizations who self-certify compliance and participate in the Framework), these mechanisms are subject to legal challenges, and there is no assurance that we can satisfy or rely on these measures to lawfully transfer personal data to the U.S. If there is no lawful manner for us to transfer personal data from the EEA, the UK, or other jurisdictions to the U.S., or if the requirements for a legally-compliant transfer are too onerous, we could face significant adverse consequences, including the interruption or degradation of our operations, the need to relocate part of or all of our business or data processing activities to other jurisdictions (such as Europe) at significant expense, increased exposure to regulatory actions, substantial fines and penalties, the inability to transfer data and work with partners, vendors and other third parties, and injunctions against our processing or transferring of personal data necessary to operate our business. Additionally, companies that transfer personal data out of the EEA and UK to other jurisdictions, particularly to the United States, are subject to increased scrutiny from regulators, individual litigants, and activist groups, and some EEA regulators have prevented companies from transferring personal data out of the EEA for allegedly violating the EU GDPR’s cross-border data transfer limitations.

As described further below, we identified a material weakness in our internal control over financial reporting that existed as of September 30, 2025. Any testing by us conducted in connection with Section 404, or any testing by our independent registered public accounting firm, may reveal additional deficiencies in our internal control over financial reporting that are deemed to be material weaknesses or that may require prospective or retroactive changes to our financial statements or identify other areas for further attention or improvement.

Previous wording

The requirements of Section 404 are ongoing and also apply to future years. We expect that our internal control over financial reporting will continue to evolve as our business develops, including in connection with our commercialization of RYTELO. Although we are committed to continue to improve our internal control processes and we will continue to diligently and vigorously review our internal control over financial reporting in order to ensure compliance with Section 404 requirements, any control system, regardless of how well designed, operated and evaluated, can provide only reasonable, not absolute, assurance that its objectives will be met. Moreover, in 2024 we implemented a new ERP and other information systems to help us manage our operations and financial reporting. However, any failure of the ERP system that we implemented in 2024 to operate as intended could negatively impact the effectiveness of our internal control over financial reporting. Therefore, we cannot assure you that material weaknesses or significant deficiencies will not exist or otherwise be discovered in the future, particularly in light of our increased reliance on personnel working remotely. If material weaknesses or other significant deficiencies occur, such weaknesses or deficiencies could result in misstatements of our results of operations, restatements of our financial statements, a decline in our stock price, or other material adverse effects on our business, reputation, results of operations, financial condition or liquidity.

Any new taxes could adversely affect our domestic and international business operations and our business and financial condition. Further, existing tax laws, statutes, rules, regulations or ordinances could be interpreted, changed, modified or applied adversely to us. For example, the Inflation Reduction Act of 2022 included provisions that impacted the U.S. federal income taxation of corporations, including imposing a minimum tax on the book income of certain large corporations and an excise tax on certain corporate stock repurchases that is imposed on the corporation repurchasing such stock. .In addition, the U.S. government recently enacted legislation commonly referred to as the One Big Beautiful Bill Act, that (along with other recent U.S. federal tax reform) has resulted in significant changes to the taxation of business entities including, among other changes, changes to the taxation of income derived from international operations, changes in the deduction and amortization of research and development expenditures, and limitations on the deductibility of business interest. Future guidance from the Internal Revenue Service and other tax authorities with respect to any legislation may affect us, and certain aspects of such legislation could be repealed or modified or sunset in future years.
