Current report

•We and certain of our current and former officers have been named as defendants in securities class action lawsuits and derivative lawsuits. These lawsuits, and potential similar or related lawsuits, could result in substantial damages, divert management’s time and attention from our business, and have a material adverse effect on our results of operations. These lawsuits, and any other lawsuits to which we are subject, will be costly to defend or pursue and are uncertain in their outcome.

Current report

•the market penetration rate of RYTELO across the breadth of eligible patient segments in its approved indication may continue to be lower than our expectations;

Current report

Although we received marketing authorization for RYTELO in the EU for the treatment of certain adult patients with transfusion-dependent anemia due to lower-risk MDS in March 2025, we currently have no marketing or sales organization outside of the U.S., and as a company, we have no experience selling and marketing approved drugs outside of the U.S. To successfully commercialize RYTELO in the EU or in any other regions outside the U.S. where we might seek marketing authorization in the future, we will need to develop these capabilities, which we plan to do by working with experienced third-party contractors or commercialization partners. Doing so will require additional investment of capital and time. Particularly in light of our current priority to drive new patient starts across the breadth of the eligible patient population in RYTELO’s approved indication in the U.S., we currently intend to seek contractual arrangements, strategic partnerships, collaborations, alliances or licensing arrangements with third parties to assist us in the commercialization of RYTELO in the EU and in any other regions outside of the U.S. where RYTELO may be approved for marketing in the future. However, we may be unable to enter into and conduct successful contractual arrangements, strategic partnerships, collaborations, alliances or licensing arrangements with third parties to commercialize RYTELO in the EU or in any other regions where RYTELO may be approved for marketing in the future. Any failure or delay in entering into and conducting such contractual arrangements, strategic partnerships, collaborations, alliances or licensing arrangements with third parties would adversely impact the commercialization of RYTELO in the EU or in any other regions outside the U.S. where RYTELO may be approved for marketing in the future.

Current report

If competitors develop products, product candidates or technologies that are superior to or more cost-effective than RYTELO, it would significantly impact the development and commercial viability of RYTELO, which would severely and adversely affect our financial results, business and business prospects, and the future of RYTELO, and might cause us to cease operations.

Current report

Smaller companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established companies. We anticipate increased competition in the future as new companies explore treatments for myeloid hematologic malignancies, which may significantly impact the commercial viability of RYTELO. Academic institutions, government agencies and other public and private research organizations may also conduct research, seek patent protection and establish collaborative arrangements for research, clinical development and marketing of products similar to RYTELO. These companies and institutions compete with us in recruiting and retaining qualified development and management personnel as well as in acquiring technologies complementary to the RYTELO program.

Current report

•regulatory authorities may withdraw approval of RYTELO;

Current report

We have employees located outside of the U.S., conduct clinical trials outside of the U.S., and are preparing to commercialize RYTELO in select EU markets beginning in 2026, which may subject us to additional risks, including risks related to operating outside of the U.S., such as:

Current report

For example, the current administration in the U.S. has called for substantial changes to foreign trade policy and has recently proposed and imposed significant increases in tariffs on international trade and the renegotiation of international trade agreements. We cannot predict what effects these and potential additional tariffs or renegotiation of existing international trade agreements will have on our business, including in the context of escalating global trade and political tensions. However, such tariffs and other trade restrictions could increase our cost of doing business, reduce our gross margins or otherwise negatively impact our financial results. See the risk factor entitled, “Global trade issues and changes in and uncertainties with respect to trade policies and export regulations, including import and export license requirements, trade sanctions, tariffs and international trade disputes, could increase our costs and negatively impact net revenues from sales of RYTELO.”

Current report

Global trade issues and changes in and uncertainties with respect to trade policies and export regulations, including import and export license requirements, trade sanctions, tariffs and international trade disputes, could increase our costs and negatively impact net revenues from sales of RYTELO.

Current report

There is inherent risk, based on the complex relationships among the U.S. and the countries in which we now conduct or may in the future conduct our business, that political, diplomatic, and national security factors can lead to global trade restrictions and changes in trade policies and export regulations that may adversely affect our business and operations. Compliance with applicable regulatory requirements regarding the export of products may create delays in the introduction of RYTELO in international markets, including in the EU, or, in some cases, prevent the export of RYTELO to some countries altogether. Furthermore, U.S. export control laws and economic sanctions prohibit the provision of certain products and services to countries, governments and persons targeted by U.S. sanctions. The U.S. and other countries have imposed and may continue to impose new trade restrictions and export regulations, have levied tariffs and taxes on certain goods, and could continue to significantly increase tariffs on a broad array of goods, including pharmaceutical and biological products.

Current report

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 July 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 report

Further, the continued threats of new or increased tariffs, sanctions, trade restrictions and trade barriers as well as ongoing changes in U.S. and foreign government trade policies, including potential modifications to existing international trade agreements, have had and may continue to have a generally disruptive impact on the global economy and, therefore, could negatively impact revenues from sales of RYTELO. Given the volatility and uncertainty regarding the scope and duration of such tariffs and other aspects of U.S. and foreign government trade policies, the ultimate impact on our operations and financial results is uncertain and could be significant in the future.

Current report

Enhanced governmental and private scrutiny over, or investigations or litigation involving, pharmaceutical manufacturer donations to patient assistance programs offered by charitable foundations may require us to modify our programs and could negatively impact our business practices, harm our reputation, divert the attention of management and increase our expenses.

Current report

To help patients afford our products, we have a patient assistance program and also occasionally make donations to independent charitable foundations that help financially needy patients. These types of programs designed to assist patients in affording pharmaceuticals have become the subject of scrutiny. In recent years, some pharmaceutical manufacturers were named in class action lawsuits challenging the legality of their patient assistance programs and support of independent charitable patient support foundations under a variety of federal and state laws. At least one insurer also has directed its network pharmacies to no longer accept manufacturer co-payment coupons for certain specialty drugs the insurer identified.

Current report

Our patient assistance program and support of independent charitable foundations could become the target of similar litigation. In addition, there has been regulatory review and enhanced government scrutiny of donations by pharmaceutical companies to patient assistance programs operated by charitable foundations. For example, the Office of Inspector General of the U.S. Department of Health & Human Services, or OIG, has established specific guidelines permitting pharmaceutical manufacturers to make donations to charitable organizations who provide co-pay assistance to Medicare patients, provided that such organizations are bona fide charities, are entirely independent of and not controlled by the manufacturer, provide aid to applicants on a first-come basis according to consistent financial criteria, and do not link aid to use of a donor’s product. If we or our vendors or donation recipients are deemed to fail to comply with laws or regulations in the operation of these programs, we could be subject to damages, fines, penalties or other criminal, civil or administrative sanctions or enforcement actions. We cannot ensure that our compliance controls, policies and procedures will be sufficient to protect against acts of our employees, business partners or vendors that may violate the laws or regulations of the jurisdictions in which we operate. A government investigation could negatively impact our business practices, harm our reputation, divert the attention of management and increase our expenses.

RISKS RELATED TO MANUFACTURING RYTELO

Current report

RISKS RELATED TO OUR OPERATING RESULTS AND FINANCIAL POSITION

Current report

Our financial projections and estimates are subject to significant risks, assumptions, and uncertainties, and our actual results may differ materially.

Current report

Our financial projections and estimates are subject to significant risks, assumptions, and uncertainties, and our actual results may differ materially. These projections and estimates include estimates of the total addressable market for RYTELO, assumptions regarding patient market share and duration of therapy for patients receiving RYTELO, as well as assumptions regarding our ability to meet demand and assumptions regarding our future costs of goods. These projections and estimates are subject to various factors beyond our control, including, for example, the level of demand for RYTELO, the extent to which coverage and reimbursement for RYTELO is available from government and health administration authorities, private health insurers, managed care programs and other third-party payors, increased costs in the supply chain, including as a result of increased tariffs, renegotiation of existing international trade agreements, escalating trade tensions and other trade restrictions, increased labor costs, changes in the regulatory environment, the impact of global health crises or macroeconomic or other global conditions, and changes in our senior management team. Our financial projections and estimates constitute forward-looking statements, are for illustrative purposes only and should not be relied upon as necessarily being indicative of future results. The assumptions and estimates underlying such financial projections and estimates are inherently uncertain and are subject to a wide variety of significant business, economic, competitive and other risks and uncertainties. Actual results may differ materially from the results contemplated by the financial projections. Our independent auditors have not studied, reviewed, compiled or performed any procedures with respect to the projections, and accordingly, they did not express an opinion or provide any other form of assurance with respect thereto. While all financial projections, estimates and targets are necessarily speculative, we believe that the preparation of financial projections involves increasingly higher levels of uncertainty the further out the projection, estimate or target extends from the date of preparation. Accordingly, there can be no assurance that the prospective results are indicative of our future performance or that actual results will not differ materially from those presented in the financial projections or estimates.

Current report

•expenses associated with the pending putative securities class action and shareholder derivative lawsuits and potential additional related lawsuits, as well as any other litigation;

Current report

In addition to orphan drug exclusivity, we expect to rely on other forms of regulatory exclusivity to protect our ability to commercialize RYTELO. In the U.S., New Chemical Entity, or NCE, exclusivity would entitle us to four years of data exclusivity and one year of market exclusivity, for a total of five years of NCE exclusivity from the date of approval of the first-approved indication. Our request for NCE exclusivity is still pending with FDA, and might not be awarded or could be awarded and then later withdrawn. In Europe, New Active Substance, or NAS, exclusivity is expected to entitle us to eight years of data exclusivity and two years of market exclusivity, for a total of ten years of NAS exclusivity for the first-approved indication, but as with other forms of regulatory exclusivity, NAS exclusivity could be limited or withdrawn.

Current report

Management transition creates uncertainties and could harm our business.

Current report

Over the past few years, we have experienced significant changes in executive leadership, and more could occur. For example, effective March 10, 2025, we appointed Dawn C. Bir, a current member of our board of directors, as our Interim President and Chief Executive Officer to serve in such capacity while we conduct a search for a permanent Chief Executive Officer. 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.

Current report

We and certain of our current and former officers and directors have been named as defendants in securities class action lawsuits and derivative lawsuits. These lawsuits, and potential similar or related lawsuits, could result in substantial damages, divert management’s time and attention from our business, and have a material adverse effect on our results of operations. These lawsuits, and any other lawsuits to which we are subject, will be costly to defend or pursue and are uncertain in their outcome.

Current report

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 Debestani 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.

Current report

In addition, on April 15, 2025 and April 16, 2025, three purported stockholders filed derivative complaints, each filed in the United States District Court for the Northern District of California, captioned Bishop v. Scarlett, et al., No. 3:25-cv-03356, Lerner v. Scarlett, et al., No. 3:25-cv-03401, and Willis v. Scarlett, et al., No: 3:25-cv-03396, respectively. The three lawsuits name certain of our current and former directors and officers and allege that they breached their fiduciary duties and violated federal securities laws by issuing allegedly false and misleading statements concerning the commercial potential of RYTELO. The allegations in each of the three derivative complaints are substantially similar to the two aforementioned securities class action lawsuits, which these lawsuits are premised on. The plaintiff seeks damages and interest, and an award of reasonable costs, including attorneys' and experts' fees. The plaintiffs in Bishop v. Scarlett, et al. and Willis v. Scarlett, et al. also seek punitive damages.

Current report

For example, under GDPR, government regulators may impose temporary or definitive bans on data processing, fines of up to 20 million Euros under the EU GDPR, 17.5 million pounds sterling under the UK GDPR or, in each case, 4% of annual global revenue, whichever is greater; or private litigation related to processing of personal data brought by classes of data subjects or consumer protection organizations authorized at law to represent their interests.

Current report

In addition, as further discussed in the Risk Factor above entitled “We and certain of our current and former officers and directors have been named as defendants in securities class action lawsuits and derivative lawsuits. These lawsuits, and potential similar or related lawsuits, could result in substantial damages, divert management’s time and attention from our business, and have a material adverse effect on our results of operations. These lawsuits, and any other lawsuits to which we are subject, will be costly to defend or pursue and are uncertain in their outcome,” we and certain of our current and former officers and directors have been named as defendants in securities class action and derivative lawsuits. Such lawsuits have often been instituted against companies, including us, whose securities have experienced periods of volatility in market price. The pending lawsuits and any lawsuits brought against us in the future could result in substantial costs and divert our management’s attention and resources, which could have a material adverse effect on our financial condition and business operations and lead to increased volatility in our stock price and a decrease in the value of our stockholders’ investment in our securities.

Current report

Our failure to maintain compliance with the continued listing requirements of the Nasdaq Global Select Market may result in our common stock being delisted from the Nasdaq Global Select Market, which could negatively impact the price of our common stock, liquidity, our ability to access the capital markets and our stockholders’ ability to sell their shares.

Current report

Our common stock is currently listed on the Nasdaq Global Select Market, or Nasdaq, under the symbol “GERN.” The listing standards of Nasdaq provide that a company, in order to qualify for continued listing, must maintain a minimum stock price of $1.00 and satisfy standards relative to minimum stockholders’ equity, minimum market value of publicly held shares and various additional requirements. Historically, our stock price has been extremely volatile and recently, our stock has traded as low as $1.17 per share. While our common stock is currently listed on Nasdaq, we can give no assurance that we will be able to maintain compliance with the continued listing requirements for Nasdaq. If we fail to maintain compliance with any such continued listing requirement, there can also be no assurance that we will be able to regain compliance with any such continued listing requirement in the future or that our common stock will not be delisted in the future. If Nasdaq delists our securities from trading on its exchange for failure to meet the listing standards, we and our stockholders could face significant negative consequences including:

Current report

•limited availability of market quotations for our securities;

Current report

• a determination that the common stock is a “penny stock” which would require brokers trading in the common stock to adhere to more stringent rules, possibly resulting in a reduced level of trading activity in the secondary trading market for shares of common stock;

Current report

• a limited amount of analyst coverage, if any; and

Current report

Delisting from Nasdaq could also result in other negative consequences, including the potential loss of confidence by suppliers, customers and employees, the loss of institutional investor interest and fewer business development opportunities.

Current report

Our business could be negatively impacted by environmental, social and corporate governance, or ESG, matters or our reporting of such matters.

Current report

There is an increasing focus from certain investors, employees, partners, and other stakeholders concerning ESG matters. We may be, or be perceived to be, not acting responsibly in connection with these matters, which could negatively impact us. For example, we currently do not report our environmental emissions and absent a legal requirement to do so we currently do not plan to report our environmental emissions, and lack of reporting could result in certain investors declining to invest in our common stock.

Current report

Furthermore, the criteria by which our ESG practices, including our initiatives and public goals, are assessed may change due to the evolution of the sustainability landscape, which could result in greater expectations of us and may cause us to undertake costly initiatives to satisfy new criteria. If we are unable to respond effectively to these changes to the sustainability landscape, governments, customers, and investors may conclude that our policies and/or actions with respect to ESG matters are inadequate. If we fail or are perceived to have failed to achieve previously announced public goals or to accurately disclose our progress on such goals or initiatives, our reputation, business, financial condition and results of operations could be adversely impacted.

Further, the status of reimbursement codes for RYTELO could also affect reimbursement. J-Codes are reimbursement codes maintained by the Centers for Medicare and Medicaid Services, or CMS, that are a component of the Healthcare Common Procedure Coding System and are typically used to report drugs that ordinarily cannot be self-administered. On October 3, 2024, CMS assigned a permanent and product specific J-code (J0870) for RYTELO, which will become effective on January 1, 2025. For the remainder of 2024, and until CMS systems are updated, physicians will continue to use the non-specific miscellaneous J-Code to bill third-party payors for RYTELO. Because miscellaneous J-Codes may be used for a wide variety of products, health plans may have more difficulty determining the actual product used and billed for the patient. These claims increase the provider administrative burden and must often be submitted with additional information and manually processed, which can delay claims processing times as well as increase the likelihood for claim denials and claim errors.

Previous report

We are seeking regulatory approval to market RYTELO in the EU, and may be subject to additional risks, including, if regulatory approval is obtained from the European Commission, risks related to operating outside of the U.S., such as:

Previous report

European Commission and other foreign regulatory approvals, if any, may take longer and be more costly to obtain than approvals in the U.S., due to differing regulatory requirements in foreign countries;

Previous report

EMA and other regulatory authorities outside of the U.S. may disagree with the design, implementation or results of our clinical trials or our interpretation of data from nonclinical studies or clinical trials;

Previous report

approval policies or regulations in the EU or of regulatory authorities outside of the U.S. may significantly change in a manner rendering our clinical data insufficient for potential approval;

Previous report

receive regulatory approval to commercialize RYTELO in lower-risk MDS from the European Commission without the requirement for the conduct and completion of additional pre-approval clinical trials or further analyses, testing or development commitments, if at all, any of which could result in increased costs to us, and delay, limit or preclude our ability to generate revenue in the EU;

Previous report

Until we can generate a sufficient amount of revenue from sales of RYTELO to finance our cash requirements, which we may never achieve, we expect to finance future cash needs through a combination of public or private equity offerings, debt financings, collaborations, strategic alliances, licensing arrangements and other marketing and distribution arrangements, which may not be possible. Availability of such financing sources may be negatively impacted by any further delays in our clinical trials, regulatory developments, or the other risks described in this section.

Previous report

In addition, our international operations in the U.K. and the Netherlands expose us to fluctuations in currency exchange rates between the British pound, the Euro and the U.S. dollar. Given the volatility of currency exchange rates, there is no assurance that we will be able to effectively manage currency transaction and/or conversion risks. To date, we have not entered into derivative instruments to offset the impact of foreign exchange fluctuations, which fluctuations could have an adverse effect on our financial condition and results of operations.

Previous report

In the past, we and certain of our officers have been named as defendants in securities class action lawsuits and shareholder derivative lawsuits. Potential similar or related lawsuits that may be filed in the future, could result in substantial damages, divert management’s time and attention from our business, and have a material adverse effect on our results of operations. Any such lawsuits, or other lawsuits to which we are subject, will be costly to defend or pursue and are uncertain in their outcome.

Previous report

If we fail to successfully implement or upgrade our enterprise resource planning and other information systems, our business and results of operation could be adversely impacted.

Previous report

We periodically implement or upgrade new or enhanced enterprise resource planning, or ERP, and other business systems in order to better manage our business operations. Implementation or upgrade of new business processes and information systems requires the commitment of significant personnel, training and financial resources, and entails risks to our business operations. If we do not successfully implement ERP and other information systems improvements, or if there are delays or difficulties in implementing these systems, we may not realize anticipated productivity improvements or cost efficiencies, and we may experience operational difficulties and challenges in effectively managing our business, all of which could result in quality issues, reputational harm, lost market and revenue opportunities, and otherwise adversely affect our business, financial condition and results of operations.

Previous report

For example, we are currently in the process of implementing new ERP and other information systems to help us manage our operations and financial reporting. This project has required and may continue to require investment of capital and human resources, the re-engineering of processes of our business, and the attention of many employees who would otherwise be focused on other aspects of our business. Costs and risks inherent in this transition may include disruptions to business continuity, administrative and technical problems, interruptions or delays in sales, expenditure overruns, delays in paying our suppliers and employees, and data migration issues. If we do not properly address or mitigate these issues, this could result in increased costs and diversion of resources, negatively impacting our operating results and ability to effectively manage our business. Additionally, if we do not effectively implement the ERP system as planned, or the ERP system does not operate as intended, the effectiveness of our internal control over financial reporting could be negatively affected.

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 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, our commercial launch of RYTELO in the U.S. may not continue as planned or anticipated, which may require us to, among others, adjust or amend our commercialization plan and incur significant expenses. 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 or if our commercialization efforts do not continue as planned, we may not be able to successfully commercialize 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 which would severely and adversely affect our financial results, business and business prospects, and might cause us to cease operations.

Current 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, although we have generated approximately $115.9 million in net product revenues since our commercial launch of RYTELO in the U.S. through March 31, 2025, as previously disclosed, weekly sales growth of RYTELO has been relatively flat since the end of the fourth quarter of 2024, which has continued in the first quarter of 2025. 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 be unable to 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 which would severely and adversely affect our financial results, business and business prospects, and might cause us to cease operations.

Previous wording

To successfully commercialize RYTELO in the U.S., we need to continue to execute on our sales, marketing and distribution plans. The ongoing execution of our sales, marketing and distribution plans is, and will continue to be, expensive and time-consuming and we cannot be certain that we will be able to continue to execute on these plans successfully. In addition, we compete with many companies that currently have extensive, experienced and well-funded sales, distribution and marketing operations to recruit, hire, train and retain marketing and sales personnel. If we are unable to recruit as needed, and to retain and effectively train marketing and sales personnel and equip them with compliant and effective materials, our efforts to successfully commercialize RYTELO could be adversely affected.

Current wording

To successfully commercialize RYTELO in the U.S., we need to continue to execute on our sales, marketing and distribution plans, including on our efforts to drive new patient starts in RYTELO's approved indication. The ongoing execution of our sales, marketing and distribution plans requires investment of capital and time, and we cannot be certain that we will be able to execute on our plans successfully in a timely manner or at all. In addition, we compete with many companies that currently have extensive, experienced and well-funded sales, distribution and marketing operations to recruit, hire, train and retain marketing and sales personnel. If we are unable to recruit as needed, and to retain and effectively train marketing, sales and medical personnel and equip them with compliant and effective materials, our efforts to successfully commercialize RYTELO could be adversely affected.

Previous wording

We currently have no marketing or sales organization outside of the U.S. We do not yet have any products approved for sale outside of the U.S, and we, as a company, have no experience selling and marketing approved drugs outside of the U.S. To successfully commercialize any approved drugs outside of the U.S, we will need to develop these capabilities, either on our own or with others. Doing so will be expensive, difficult and time-consuming. If we receive regulatory approval to commercialize RYTELO in any other regions, such as the EU, we may seek strategic partnerships, collaborations, alliances or licensing arrangements, at an appropriate time, to assist us in the potential development and commercialization of RYTELO, or we may seek to self-commercialize and need to establish business operations in such regions. We may be unsuccessful in our efforts to recruit, hire, train and retain personnel to support such business operations; or we may be unable to enter into and conduct successful strategic partnerships, collaborations, alliances or licensing arrangements with third parties to commercialize RYTELO in such regions, should we seek to do so. Any failure or delay in the development of our internal sales, marketing and distribution capabilities would adversely impact the commercialization of RYTELO outside the U.S.. Further, given our lack of prior experience in marketing and selling our product, our initial estimate of the size of the required sales force may be materially more or less than the size of the sales force actually required to effectively commercialize our product. As such, we may be required to hire substantially more sales representatives and medical support liaisons to adequately support the commercialization of RYTELO, if approved, or we may incur excess costs as a result of hiring more sales representatives than necessary. With respect to certain geographical markets, we may enter into arrangements with other entities 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 our potential future partners do not commit sufficient resources to commercialize our future products, if any, and we are unable to develop the necessary marketing capabilities on our own, we will be unable to generate sufficient product revenue to sustain our business. If we are unable to establish sales and marketing capabilities for RYTELO, whether on our own or through collaborations, our results of operations will 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.

Current wording

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.

Previous wording

If we do not obtain acceptable prices or adequate reimbursement for RYTELO, the use of RYTELO could be severely limited.

Current wording

If we do not maintain acceptable prices or adequate reimbursement for RYTELO, the use of RYTELO could be severely limited.

Previous wording

Our ability to successfully commercialize RYTELO will depend significantly on obtaining acceptable prices and the availability of coverage and adequate reimbursement to patients from third-party payors. Government payors, such as the Medicare and Medicaid programs, and other third-party payors, such as private health insurers and health maintenance organizations, determine which medications they will cover and the reimbursement levels. Although we have received a permanent and product-specific J-code (J0870) for RYTELO which will become effective on January 1, 2025, the resulting reimbursement payment rates may not be adequate or may require significant restrictions on use or increased co-payments from commercially insured patients that patients may find unacceptably high. Patients are unlikely to use RYTELO unless coverage is provided, and reimbursement is adequate to cover all or a significant portion of its cost. Therefore, coverage and adequate reimbursement will be critical to market acceptance of RYTELO.

Previous wording

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, or the Inflation Reduction Act, 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.

We cannot be sure that coverage and reimbursement will be available for RYTELO, and, if reimbursement is available, what the level of reimbursement will be. Although we have received a permanent and product-specific J-code (J0870) for RYTELO which will become 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. 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.

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.

Previous wording

RYTELO may not achieve market acceptance in the U.S. 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 if approved outside the U.S., since hospitals, physicians, patients or the medical community in general may decide not to accept and utilize RYTELO. 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:

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.

We may be unable to demonstrate any therapeutic or economic advantage for RYTELO compared to established or standard-of-care therapies, or newly developed therapies, for myeloid hematologic malignancies. Third-party payors may decide that any potential benefit that RYTELO may provide to clinical outcomes in myeloid hematologic malignancies is not adequate to justify the potential adverse effects or the costs of treatment with RYTELO. If the healthcare community does not accept RYTELO for any of the foregoing reasons, or for any other reasons, our ability to commercialize RYTELO in the U.S. for lower-risk MDS may be negatively impacted or precluded altogether, which would seriously and adversely affect our business and business prospects.

We are commercializing RYTELO in lower-risk MDS, and the addressable patient population in lower-risk MDS is based on our estimates. These estimates, which have been derived from a variety of sources, including scientific literature, surveys of clinics, patient foundations and market research, may prove to be incorrect. Further, new information from us or others may change the estimated incidence or prevalence of patients with lower-risk MDS in the U.S. Additionally, the potentially addressable patient population for RYTELO may not ultimately be amenable to treatment with RYTELO, or we may be unable to successfully identify patients and achieve a significant market share in RYTELO’s approved indication, or initial sales of RYTELO may deplete the prevalence pool of patients in the RYTELO’s approved indication more quickly than expected, which would have a negative impact on sales of RYTELO in the future. Our commercialization of RYTELO in the U.S. is limited to lower-risk MDS, and any future potential commercialization will be limited to the therapeutic indications examined in our clinical trials and as determined by the FDA and similar international regulatory authorities, which would not permit us to market RYTELO for any other indications not expressly approved by those regulatory authorities. Future regulatory approvals for RYTELO, if any, could be conditioned upon label restrictions that materially limit the addressable patient population.

The pharmaceutical and biotechnology industries are characterized by intense and dynamic competition with rapidly advancing technologies and a strong emphasis on proprietary products. While we believe our proprietary oligonucleotide chemistry; experience with the biological mechanisms related to telomeres and telomerase; clinical data to date; and knowledge and expertise around the development of potential treatments for myeloid hematologic malignancies provide us with competitive advantages, we face competition from many different sources, including major pharmaceutical, specialty pharmaceutical and biotechnology companies, academic institutions, governmental agencies, and public and private research institutions. RYTELO will compete with other products and therapies that currently exist, are being developed or will in the future be developed, some of which we may not currently be aware of. For a description of the competition that RYTELO may face in our lead indications of lower-risk MDS and relapsed/refractory MF, see Item 1, “Business - Competition” in our 2023 Form 10-K.

A discussion of current and potential future competitors of RYTELO can be found in the sub‑section entitled “Competition” in Part I, Item 1, entitled “Business” included in our Annual Report on Form 10-K for the year ended December 31, 2024.

Previous wording

Many of our competitors, either alone or with their strategic partners, could have substantially greater financial, technical and human resources than we do and significantly greater experience in obtaining FDA and other regulatory approvals of treatments and commercializing those treatments.

Current wording

Many of our competitors, either alone or with their strategic partners, could have substantially greater financial, technical and human resources than we do and significantly greater experience in obtaining FDA and other regulatory approvals of treatments and commercializing those treatments. We believe that the commercial success of RYTELO is subject to a number of factors, including: product efficacy and safety; method of product administration; cost of manufacturing; the timing and scope of regulatory consents; status of coverage and reimbursement; price; the level of generic competition; and our patent and regulatory exclusivity position.

Previous wording

Competitors may have or develop more commercially desirable or affordable products than RYTELO, or achieve earlier or longer patent and regulatory exclusivity protection or product commercialization than we may be able to achieve with RYTELO. Some of these products may have an entirely different approach or means of accomplishing therapeutic effects similar or superior to those that may be demonstrated by RYTELO. Competitors may have or develop products that are safer, more effective, or less costly than RYTELO, or more convenient to administer to patients. In addition, competitors may price their products below our price for RYTELO, may receive better third-party payor coverage and/or reimbursement, or may be more cost-effective than RYTELO. Such competitive products or activities by competitors may limit the commercial potential of RYTELO, which may cause us to cease commercialization and any further development of RYTELO, which would severely and adversely affect our financial results, business and business prospects, and might cause us to cease operations.

Current wording

As a result of the foregoing, competitors may develop more commercially desirable or affordable products than RYTELO or achieve earlier patent protection or product commercialization than we may be able to achieve with RYTELO. Competitors have developed, or are in the process of developing, technologies that are, or in the future may be, competitive to RYTELO. Some of these products may have an entirely different approach or means of accomplishing therapeutic effects similar or superior to those that may be demonstrated by RYTELO. Competitors may develop products that are safer, more effective, or less costly than RYTELO, or more convenient to administer to patients and, therefore, present a serious competitive threat to RYTELO. In addition, competitors may price their products below what we may determine to be an acceptable price for RYTELO, may receive better third-party payor coverage and/or reimbursement, or may be more cost-effective than RYTELO. Such competitive products or activities by competitors may render RYTELO obsolete, which may cause us to cease any further development or future commercialization of RYTELO, which would severely and adversely affect our financial results, business and business prospects, and the future of RYTELO, and might cause us to cease operations.

Previous wording

We rely on a select network of third party distributors, specialty pharmacies and other vendors to distribute RYTELO, and the financial failure of any of these parties could adversely affect our revenues, financial condition or results of operations. We rely on such distributors and specialty pharmacies to effectively distribute RYTELO in a timely manner, provide certain patient support services, manage prescription intake, collect accurate patient and inventory data and collect payments from payors. While we have entered into agreements with each of these parties, they may not perform as agreed, our strategic priorities may change or they may terminate their agreements with us. Further, an inability by our distributors or specialty pharmacies to meet our patients’ needs may lead to reputational harm or patient loss. In the event that such network fails to properly meet our or our patients’ needs, we may need to partner with other distributors, specialty pharmacies or vendors to replace or supplement our current network and there is no guarantee that we will be able to do so on commercially reasonable terms or at all.

Current wording

We will be subject to pricing, drug marketing, post-market and reimbursement regulations in the EU, which may materially affect our ability to commercialize and receive reimbursement coverage for RYTELO in the EU.

Previous wording

We are seeking approval to market RYTELO in the EU for lower-risk MDS. Even if we obtain approval for RYTELO in the EU, the competent regulatory authorities may still impose significant restrictions on the indicated uses or marketing of our product or impose ongoing requirements for potentially costly post-approval studies, post-market surveillance or patient or drug restrictions. We will also be subject to rules and regulations in the EUapplicable to the manufacturing, marketing, promotion and sale of medicinal products. If we or a regulatory authority discovers previously unknown problems with RYTELO, such as adverse events of unanticipated severity or frequency, or problems with a facility where RYTELO is manufactured, a regulatory authority may impose restrictions relative to RYTELO or the manufacturing facility, including requiring recall or withdrawal of RYTELO from the market or suspension of manufacturing. Moreover, product labeling, advertising and promotion for RYTELO will be subject to regulatory requirements and continuing regulatory review.

In March 2025, we received marketing authorization for RYTELO in the EU for the treatment of adult patients with transfusion-dependent, or TD, anemia due to lower-risk MDS without an isolated deletion 5q cytogenic abnormality and who had an unsatisfactory response to or are ineligible for erythropoietin-based therapy. In connection with such approval, we are subject to post-marketing requirements to submit final results from certain ongoing non-clinical and clinical studies and the completion of certain quality-related activities and study. We are also subject to rules and regulations in the EU applicable to the manufacturing, marketing, promotion and sale of medicinal products. If we or a regulatory authority discovers previously unknown problems with RYTELO, such as adverse events of unanticipated severity or frequency, or problems with a facility where RYTELO is manufactured, a regulatory authority may impose restrictions relative to RYTELO or the manufacturing facility, including requiring recall or withdrawal of RYTELO from the market or suspension of manufacturing. Moreover, product labeling, advertising and promotion for RYTELO will be subject to regulatory requirements and continuing regulatory review.

Previous wording

In addition, the pricing of RYTELO will be subject to governmental control and other market regulations which could put pressure on the pricing and usage of RYTELO. In the EU, pricing negotiations with governmental authorities can take considerable time after obtaining marketing approval of a product candidate. In addition, if approved, market acceptance and sales of RYTELO will depend significantly on the availability of adequate coverage and reimbursement from third-party payors for RYTELO and may be affected by existing and future healthcare reform measures.

Previous wording

The requirements governing drug pricing and reimbursement vary widely from country to country. For example, the EU provides options for its member states to restrict the range of medicinal products for which their national health insurance systems provide reimbursement and to control the prices of medicinal products for human use. Reference pricing used by various EU Member States and parallel distribution, or arbitrage between low-priced and high-priced EU Member States, can further reduce prices. An EU Member State may approve a specific price for the medicinal product or it may instead adopt a system of direct or indirect controls on the profitability of the company placing the medicinal product on the market. If RYTELO is approved for commercialization in the EU, in some countries, we may be required to conduct a clinical study or other studies that compare the cost-effectiveness of RYTELO to other available therapies in order to obtain or maintain reimbursement or pricing approval. There can be no assurance that any country that has price controls or reimbursement limitations for biopharmaceutical products will allow favorable reimbursement and pricing arrangements for RYTELO, if it is approved for marketing in the EU. Historically, products launched in the EU do not follow price structures of the U.S. and generally prices tend to be significantly lower. Publication of discounts by third-party payors or authorities may lead to further pressure on the prices or reimbursement levels within the country of publication and other countries. If pricing is set at unsatisfactory levels or if reimbursement of RYTELO is unavailable or limited in scope or amount, our revenues from sales and the potential profitability of RYTELO in those countries would be negatively affected.

Previous wording

In June 2024, we received regulatory approval from the FDA to commercialize RYTELO in the U.S. in lower-risk MDS. Federal, state and local governments in the U.S. have significant regulations in place that may limit or prevent us from successfully commercializing RYTELO in the U.S. for lower-risk MDS. We do not currently have regulatory approval for RYTELO in any other jurisdiction or for any other indication, and governments in other jurisdictions have significant regulations that may limit or prevent us from successfully commercializing RYTELO in other jurisdictions. Failure to maintain regulatory approval for RYTELO from the FDA in the U.S. for lower-risk MDS, or delays in obtaining, failure to obtain, or limitations in the scope of such approvals in any other jurisdictions or for any other indications, could:

If we were to experience such an attack, extortion payments might alleviate the negative impact of a ransomware attack, but we might be unwilling or unable to make such payments due to, for example, applicable laws or regulations prohibiting such payments. Similarly, supply-chain attacks and attacks on clinical trial sites as well as regulatory and health authorities have increased in frequency and severity, and we cannot guarantee that third parties and infrastructure in our supply chain or our third-party partners’ supply chains, or of clinical trial sites and regulatory and health authorities, have not been compromised or that they do not contain exploitable defects or bugs that could result in a breach of or disruption to our information technology systems or the third-party information technology systems that support us and the services provided to us, or remediate and recover compromised systems in a timely manner. For example, in February 2024, one of our service providers that processes clinical trial data experienced a security incident that resulted in certain of the service provider’s information systems being unavailable for a limited period of time. Based on the service provider’s forensic investigation findings that were shared with us, we believe that this incident did not have a material impact on us, our clinical trials or clinical trial participants. As another example, in March 2024, we learned about another security incident, involving another service provider, that processes personnel data for our limited number of UK personnel and directors of Geron UK Ltd. Following the service provider’s forensic investigation, the service provider informed us that it did not determine the specific data involved or the incident’s impact. While we believe that this incident did not have a material impact on us, out of an abundance of caution, we submitted a notification to the UK Information Commissioner’s Office and notified potentially affected personnel and directors of the incident.

Current report — wording carried from elsewhere

Any of these or similar incidents or threats may result in unauthorized, unlawful or accidental loss, corruption, access, modification, destruction, alteration, acquisition or disclosure of sensitive information, such as clinical trial data or information, intellectual property, proprietary business data and personal data. The costs to us to attempt to protect against such security incidents could be significant, including potentially requiring us to modify our business, and while we have implemented security measures, policies and procedures designed to protect our information technology systems from cybersecurity threats and to identify and remediate vulnerabilities, such measures may not be fully implemented, complied with or successful in protecting our systems and information. We may expend significant resources or modify our business activities (including our clinical trial activities) to try to protect against security incidents. We may be unable in the future to detect cybersecurity threats or vulnerabilities in our information technology systems because such threats and techniques change frequently, are sophisticated in nature, and may not be detected until after a security incident has occurred. We may also experience security breaches that may remain undetected for an extended period. Even if identified, we may be unable to adequately investigate or remediate incidents or breaches due to attackers increasingly using tools and techniques that are designed to circumvent controls, to avoid detection, and to remove or obfuscate forensic evidence. Unremediated high risk or critical vulnerabilities pose material risks to our business, particularly due to the reliance on software vendors to adequately patch and implement fixes to address critical or high-risk vulnerabilities in a timely manner. Further, we may be materially impacted by software updates applied by our software vendors if such updates cause significant downtime to our systems.

Although orphan drug designation has been granted to RYTELO for the treatment of MDS and MF in the U.S. and in the EU, these designations may not be maintained, which would eliminate the benefits associated with orphan drug designation, including market exclusivity, which could limit the period of exclusivity we are able to maintain for the commercialization of RYTELO, and would likely harm our business and business prospects.
