Previous wording

We are currently operating in a period of economic uncertainty and capital markets disruption, which has been significantly impacted by geopolitical instability, ongoing military conflicts, including the ongoing war between Russia and Ukraine, the Israel-Hamas conflict and conflict in the Middle East, the evolving regulatory activities and economic policies under the current U.S. government, events related thereto, such as changes to candidates or political unrest or otherwise, and high inflation and interest rates and the imposition of tariffs, any of which could have a material adverse effect on our business, financial condition and results of operations.

Previous wording

Investment in biopharmaceutical product development is highly speculative because it entails substantial upfront capital expenditures and significant risk that any potential product candidate will fail to demonstrate adequate effect or an acceptable safety profile, gain regulatory approval and become commercially viable. We invested substantial resources into our product development efforts of AMX0035, and toward the commercialization of AMX0035 as RELYVRIO for ALS, which was approved by the FDA, and ALBRIOZA and, received marketing authorization with conditions from Health Canada. We voluntarily discontinued the marketing authorizations for RELYVRIO/ALBRIOZA for ALS and removed the product from the market in the U.S. and Canada based on topline results from the Phase 3 PHOENIX trial, which failed to meet its prespecified primary and secondary endpoints. Following the withdrawal of RELYVRIO/ALBRIOZA from the market in the US and Canada, respectively, we do not have any products approved for commercial sale and we will continue to incur significant research and development and other expenses related to clinical development and potential approvals for our current and future product candidates, including for avexitide, AMX0035 and AMX0114 in additional indications other than ALS, and for ongoing operations. Since our inception, we have devoted the majority of our financial resources and efforts to research and development, including preclinical studies and our clinical trials, preparation for commercialization and commercialization activities. Our financial condition and operating results, including our revenues, expenses and net income (loss), have in the past and are likely in the future to fluctuate significantly from quarter to quarter and year to year. For example, we generated revenues of $380.8 million in 2023 as a result of sales of RELYVRIO/ALBRIOZA, but following its withdrawal, we will no longer generate revenues from this product. Accordingly, you should not rely upon the results of any prior quarterly or annual periods as indications of future operating performance. Additionally, net losses and negative cash flows have had, and may in the future have, an adverse effect on our stockholders’ equity and working capital. As of September 30, 2025, we had an accumulated deficit of $718.4 million.

Our operations have consumed substantial amounts of cash since inception. We expect to spend substantial amounts to continue the clinical development of avexitide, the clinical development of AMX0035 in indications other than ALS, and for the preclinical and clinical development of additional product candidates, or in the in-license, acquisition or development of other product candidates or products. If we are unable to obtain additional marketing approvals for avexitide, AMX0035, or for any other current or future product candidates that we develop, in-license or acquire, we may require significant additional amounts of cash in order to continue to develop avexitide, AMX0035, AMX0114 and any other current or future product candidates and fund our operations. In addition, other unanticipated costs may arise in the course of our development efforts. Because the design and outcome of our ongoing and anticipated clinical trials is highly uncertain, we cannot reasonably estimate the actual amounts necessary to successfully complete the development and commercialization of any product candidate we develop.

The rules dealing with U.S. federal, state, local and international income taxation are constantly under review by persons involved in the legislative process and by the Internal Revenue Service and the U.S. Treasury Department. For example, the One Big Beautiful Bill Act, or the OBBBA, was signed into law on July 4, 2025 and made significant changes to the U.S. federal tax law. Changes to tax laws (which changes may have retroactive application) could adversely affect us or holders of our common stock. For example, under Section 174 of the Internal Revenue Code of 1986, as amended, or the IRC, in taxable years beginning after December 31, 2021, expenses that are incurred for research and development performed outside the U.S. will be capitalized and amortized, which may have an adverse effect on our cash flow. The OBBBA provides that for taxable years beginning after December 31, 2024, expenses that are incurred for research and development performed in the U.S. may, at the taxpayer’s election, be immediately deducted or capitalized and amortized. In addition, the OBBBA provides that for taxable years beginning after December 31, 2021 and before January 1, 2025, certain eligible taxpayers generally may elect to retroactively deduct expenses for research and development performed in the U.S. in such taxable years by filing amended tax returns for such taxable years, and all other taxpayers that are not eligible to make such an election and that amortized expenses for research and development performed in the U.S. in such taxable years generally may elect to accelerate and deduct the remaining unamortized amounts of such research and development expenses (i) in the first taxable year beginning after December 31, 2024, or (ii) ratably over the two-taxable year period beginning with the first taxable year beginning after December 31, 2024. In recent years, many changes to tax laws have been made and changes are likely to continue to occur in the future. The OBBBA also makes significant changes to the Medicaid, Medicare, and Health Insurance Marketplace federal healthcare programs. Changes include new requirements states must meet to maintain federal support for the Medicaid programs, as well as stricter criteria beneficiaries must meet to qualify for and maintain enrollment in federal healthcare programs. The effect of these changes could result in reductions in our patient population and managed care enrollees that we serve across our federal healthcare program lines of business due to, among other things, more stringent eligibility requirements such as the imposition of work or community service requirements, and copayments on many services, limitation of Medicaid eligibility to certain lawfully present individuals, and the effect of immigration enforcement actions which may discourage beneficiaries from applying or reapplying for federal healthcare benefits.

Inflation and increases in interest rates have led to a decline in the trading value of previously issued government securities with interest rates below current market interest rates. Although the U.S. Department of Treasury, Federal Deposit Insurance Corporation, or FDIC, and Federal Reserve Board have announced a program to provide up to $25 billion of loans to financial institutions secured by certain government securities held by financial institutions to mitigate the risk of potential losses on the sale of such instruments, widespread demands for customer withdrawals or other liquidity needs of financial institutions for immediate liquidity may exceed the capacity of such program. Additionally, there is no guarantee that the U.S. Department of Treasury, FDIC and Federal Reserve Board will provide access to uninsured funds in the event of the closure of other banks or financial institutions in the future, or that they would do so in a timely fashion.

Our future success depends significantly on our ability to successfully develop, and obtain regulatory approvals for and commercialize, avexitide in PBH and AMX0035 in indications other than ALS, including Wolfram syndrome. Avexitide has been evaluated in five Phase 1 and Phase 2 clinical trials for PBH and has also been studied in Congenital HI. In February 2025, we activated the first sites for the pivotal Phase 3 LUCIDITY clinical trial for avexitide in PBH and in April 2025, we announced that the first participant had been dosed. To date, we have obtained limited clinical trial data supporting AMX0035 in indications other than ALS, having only completed a clinical trial in 95 patients with AD. We are conducting a Phase 2 clinical trial of AMX0035 in Wolfram syndrome and intend to conduct additional clinical trials for other indications and product candidates in the future. Our business success depends heavily on our ability to successfully complete clinical trials for our product candidates. We have completed the IND enabling studies of AMX0114 in ALS and the first site was activated for a Phase 1 multiple ascending dose, placebo-controlled trial in Canada in February 2025. In April 2025, we announced that the first participant of the Phase 1 clinical trial of AMX0114 had been dosed.

All participants have been randomized and dosed as of the first quarter of 2026, and we continue to expect topline data in the third quarter of 2026, and if approved, a commercial launch in 2027. We reported positive topline results from the Phase 2 HELIOS trial, an open-label study of AMX0035 in 12 adult participants with Wolfram syndrome. At Week 24, stabilization or improvement was demonstrated across all key clinical measures, including pancreatic function, glycemic control, and vision. Long-term Week 48 data demonstrated that treatment with AMX0035 led to continued sustained stabilization or improvement. Our business success depends heavily on our ability to successfully complete clinical trials for our product candidates. We have completed the IND-enabling studies of AMX0114 in ALS and fully enrolled cohort 1 (n=12) and cohort 2 (n=12) of the Phase 1 LUMINA trial in ALS in September 2025 and March 2026, respectively.

We have focused our research and development efforts on addressing neurodegenerative diseases and have only recently further expanded upon our existing development efforts in the endocrine and metabolic field with the acquisition of avexitide. This shift in focus may result in additional costs arising from operating expenses and hiring personnel, challenges with building our expertise in the endocrine and metabolic field, or diversion of management’s attention away from AMX0035. Historically, efforts by pharmaceutical companies in the field of neurodegenerative diseases have experienced limited successes in product development. The development of neurodegenerative therapies presents unique challenges, including an imperfect understanding of the biology, the presence of the blood brain barrier that can restrict the flow of drugs to the brain, a frequent lack of translatability of preclinical study results in subsequent clinical trials and dose selection, and the product candidate having an effect that may be too small to be detected using the outcome measures selected in clinical trials or if the outcomes measured do not reach statistical significance. There are few approved therapeutic options available for patients with ALS and other neurodegenerative disorders. Our future success is highly dependent on the successful development and commercialization of avexitide, AMX0035 and any other current or future product candidates for treating neurodegenerative diseases or for treating endocrine and metabolic disorders. Developing and commercializing avexitide, AMX0035 and any other current or future product candidates for treatment of neurodegenerative diseases or for treating PBH and Congenital HI subjects us to a number of challenges, including ensuring that we have developed or acquired the requisite expertise in these areas, selected the optimal doses, execute appropriate clinical trials to test for efficacy and obtain regulatory approval from the FDA and other comparable foreign regulatory authorities.

Developing and commercializing avexitide, AMX0035 and any other current or future product candidates for treatment of neurodegenerative diseases or for treating PBH and congenital HI subjects us to a number of challenges, including ensuring that we have developed or acquired the requisite expertise in these areas, selected the optimal doses, execute appropriate clinical trials to test for efficacy and obtain regulatory approval from the FDA and other comparable foreign regulatory authorities.

Previous wording

We, and any future collaborators, are not permitted to commercialize, market, promote or sell any product candidate in the U.S. or elsewhere without obtaining regulatory approval from the FDA and other comparable foreign regulatory authorities. Regulatory authorities in other jurisdictions may have similar requirements. The time required to obtain approval by the FDA and other comparable foreign regulatory authorities is unpredictable, and typically takes many years following the commencement of clinical trials and depends upon numerous factors, including substantial discretion of such regulatory authorities. In addition, approval policies, regulations, or the type and amount of clinical data necessary to gain approval may change during the course of a product candidate’s clinical development and may vary among jurisdictions. For example, the U.S. Supreme Court’s July 2024 decision to overturn prior established case law giving deference to regulatory agencies’ interpretations of ambiguous statutory language has introduced uncertainty regarding the extent to which the FDA’s regulations, policies, and decisions may become subject to increasing legal challenges, delays, and/or changes. In addition, the FDA in any approval needs to determine that there is substantial evidence of effectiveness. This finding can be substantiated based on two adequate and well-controlled studies, or in certain circumstances on a single, large, multicenter, adequate and well-controlled study that is very persuasive or from a single adequate and well-controlled study together with confirmatory evidence. FDA regulations and guidance also allow for greater flexibility and tolerance for uncertainty in the context of rare and fatal diseases.

In February 2026, the FDA Commissioner publicly indicated that a single adequate and well-controlled pivotal clinical trial supported by confirmatory evidence will be the FDA’s default standard moving forward for novel products, rather than two such trials; this statement was not a formal agency action, and the scope, implementation and durability of this policy position remain uncertain. FDA retains broad discretion to require additional clinical data for any product candidate, including a second adequate and well-controlled clinical trial.

Previous wording

This lengthy approval process as well as the unpredictability of clinical trial results may result in our failing to obtain regulatory approval to market avexitide, AMX0035 or any future product candidate we develop, which would significantly harm our business, results of operations and prospects. There is no assurance that the endpoints and trial designs used for the approval of currently approved drugs for the treatment of neurodegenerative diseases will be acceptable for future approvals, including for avexitide, AMX0035, AMX0114 and any current or future product candidates. Similarly, there is no assurance that the endpoints and trial designs for avexitide will be acceptable for its future approval. The FDA and other comparable foreign authorities have substantial discretion in the approval process and determining when or whether regulatory approval will be obtained for any product candidate that we develop. Even if we believe the data collected from past or future clinical trials of avexitide, AMX0035 or any other current or future product candidates are promising, such data may not be sufficient to support approval by the FDA or any other regulatory authority.

Previous wording

To obtain regulatory approval to commercialize avexitide, AMX0035, AMX0114 and any other current or future product candidates, we must demonstrate through extensive preclinical studies and clinical trials that such product candidates are safe and effective in humans. Preclinical and clinical testing are expensive and can take many years to complete, and their outcome is inherently uncertain. Failure can occur at any time during the clinical trial process and our future clinical trial results may not be successful, which could impact our ability to obtain regulatory approvals for avexitide, AMX0035, AMX0114 or any other current or future product candidates.

Previous wording

Negative or inconclusive impressions of the results from earlier clinical trials of avexitide performed by Eiger or any other clinical trial or preclinical studies in animals that we or Eiger, with respect to avexitide, have conducted, or the results from our earlier clinical trials of AMX0035 for the treatment of ALS or AD, could mandate repeated or additional preclinical studies or clinical trials and could delay marketing approvals or result in changes to or delays in preclinical studies or clinical trials of AMX0035 in other indications. We do not know whether any clinical trials that we may conduct will demonstrate adequate efficacy and safety to result in regulatory approval to market avexitide, AMX0035 for our intended indications or any future product candidate.

Current wording

In July 2024, we completed the acquisition of substantially all of the rights, title and interests in, to and under those assets and interests used by Eiger BioPharmaceuticals, Inc., or Eiger, in the development, manufacture and commercialization of avexitide. Negative or inconclusive impressions of the results from earlier clinical trials of avexitide performed by Eiger or any other clinical trial or preclinical studies in animals that we or Eiger, with respect to avexitide, have conducted, or the results from our earlier clinical trials of AMX0035 for the treatment of ALS or AD, could mandate repeated or additional preclinical studies or clinical trials and could delay marketing approvals or result in changes to or delays in preclinical studies or clinical trials of AMX0035 in other indications.

Previous wording

The results of preclinical studies may not be predictive of the results of clinical trials, and the results of any early-stage clinical trials we commence may not be predictive of the results of the later-stage clinical trials. In addition, initial data in clinical trials may not be indicative of results obtained when such trials are completed. There can be no assurance that any of our clinical trials will ultimately be successful or support further clinical development of avexitide, AMX0035 or any other current or future product candidates. For example, the clinical results seen in the CENTAUR trial were different than the results seen in our global Phase 3 PHOENIX clinical trial. There is a high failure rate for drugs and biologics proceeding through clinical trials. A number of companies in the pharmaceutical and biotechnology industries have suffered significant setbacks in clinical development even after achieving promising results in earlier studies, and any such setbacks in our clinical development could have a material adverse effect on our business and operating results.

Previous wording

Patient enrollment is a significant factor in the timing of clinical trials, and the timing of our clinical trials depends, in part, on the speed at which we can recruit patients to participate in our trials, as well as completion of required follow-up periods. We may not be able to initiate or continue clinical trials for avexitide, AMX0035 or any other current or future product candidates if we are unable to locate and enroll a sufficient number of eligible patients to participate in these trials to such trial’s conclusion as required by the FDA or other comparable foreign regulatory authorities. Additionally, certain clinical trials for avexitide, AMX0035 and any other current or future product candidates may be focused on indications with relatively small patient populations, which may further limit enrollment of eligible patients or may result in slower enrollment than we anticipate. The eligibility criteria of our clinical trials, once established, may further limit the pool of available trial participants. For example, the number of patients suffering from Wolfram syndrome and PBH, is small and, in some cases, has not been established with precision. If the actual number of patients with these diseases is smaller than we anticipate, we may encounter difficulties in enrolling patients in our clinical trials, thereby delaying or preventing development and approval of avexitide, AMX0035 or any other current or future product candidates. Even once enrolled, we may be unable to retain a sufficient number of patients to complete any of our trials. Neurodegenerative diseases have particular challenges, including significant mobility issues, morbidities and other complications that have historically made retention in clinical trials more challenging. In the past, we have had discontinuations in our clinical trials, including in our CENTAUR trial and our PHOENIX trial, and their open label extensions. Discontinuations may occur in current or future trials and could result in delays of completion of our clinical trials and affect our ability to enroll additional patients in our clinical trials and impact the integrity of data from our clinical trials.

Previous wording

Any negative results we may report in clinical trials of avexitide, AMX0035 or any future product candidate may also make it difficult or impossible to recruit and retain patients in other clinical trials of that same product candidate. For example, the PHOENIX trial did not meet its primary or secondary endpoints, which may discourage patients from participating in clinical trials of AMX0035 in other indications. Delays or failures in planned patient enrollment or retention may result in increased costs, program delays or both, which could have a harmful effect on our ability to develop AMX0035 in Wolfram syndrome and additional indications, avexitide and any other current or future product candidates, or could render further development impossible. Further, if patients drop out of our clinical trials, miss scheduled doses or follow-up visits, or otherwise fail to follow clinical trial protocols, whether as a result of public health epidemics and related illness, the integrity of data from our clinical trials may be compromised or not accepted by the FDA or other regulatory authorities, which would represent a significant setback for the applicable program. In addition, we may rely on CROs and clinical trial sites to ensure proper and timely conduct of our future clinical trials and, while we intend to enter into agreements governing their services, we will be limited in our ability to compel their actual performance.

Previous wording

Undesirable side effects caused by avexitide, AMX0035, AMX0114 or any future product candidate, could cause us or regulatory authorities to interrupt, delay or halt clinical trials and could result in a more restrictive label or the delay, denial or withdrawal of regulatory approval by the FDA or comparable foreign regulatory authorities. Results of our preclinical studies or clinical trials could reveal a high and unacceptable severity and prevalence of side effects or unexpected characteristics. In clinical trials to date of avexitide, avexitide was generally well-tolerated. The most common AEs were injection site bruising, headache, and nausea; these occurred more often with placebo than either avexitide dose. However, there can be no guarantee that we would observe a similar tolerability profile of avexitide in future clinical trials or for other indications.
