In addition to the other information set forth in this Quarterly Report on Form 10-Q, you should carefully consider the factors discussed in Part I, “Item 1A. Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2025 (the “2025 Form 10-K”), which could materially affect our business, financial condition or future results. The risk factors disclosure in our 2025 Form 10-K is qualified by the information that is described in this Quarterly Report on Form 10-Q. The risks described in our 2025 Form 10-K are not our only risks. Additional risks and uncertainties not presently known to us or that we currently believe to be immaterial also may materially adversely affect our business, financial condition or future results. There have been no material changes to our risk factors as previously disclosed in the 2025 Form 10-K except as follows:

Risks Related to Regulatory Approval and Commercialization

We have received orphan drug designation for CMP-001 and CMP-002 in certain jurisdictions, are pursuing orphan drug designation for CMP-002 in the United States, and may seek orphan drug designation for other product candidates in the future. We may not be able to obtain or maintain the benefits of orphan drug designation, including potential orphan drug exclusivity, and even if we do, that exclusivity may not prevent regulatory authorities from approving other competing products.

The FDA granted orphan drug designation to CMP-001 for the treatment of UCDs in September 2024. In addition, the EMA granted orphan drug designation to CMP-002 for the treatment of SYNGAP1 in April 2026, and we have submitted an orphan drug designation request to the FDA for CMP-002. However, we may not be able to obtain or maintain the benefits of such designations, including potential orphan drug exclusivity. Additionally, we may seek orphan drug designation for certain of our other product candidates in the future; however, we may never receive such designations. Under the Orphan Drug Act, the FDA may designate a product candidate as an orphan drug if it is a drug intended to treat a rare disease or condition, defined as a patient population of fewer than 200,000 in the United States, or a patient population greater than 200,000 in the United States where there is no reasonable expectation that the cost of developing the drug will be recovered from sales in the United States Orphan drug designation must be requested before submitting an NDA. A similar regulatory scheme governs orphan products in the EU and the United Kingdom based on, among others, prevalence of the disease or condition of less than 5 in 10,000.

Orphan drug designation entitles a party to financial incentives such as opportunities for grant funding towards clinical trial costs, tax advantages and application fee waivers. After the FDA grants orphan drug designation, the generic identity of the product candidate and its potential orphan use are disclosed publicly by the FDA. In addition, if a product candidate with an orphan drug designation subsequently receives the first marketing approval for the indication for which it has such designation, the product is entitled to a period of marketing exclusivity, which precludes the FDA from approving another marketing application for the same product for the same therapeutic indication for seven years.

Even if we obtain orphan drug exclusivity for a product, that exclusivity may not effectively protect the product from competition because different products can be approved for the same condition. In addition, even after an orphan drug is approved, the FDA can subsequently approve the same product for the same condition if the FDA concludes that the later product is clinically superior in that it is shown to be safer, more effective or makes a major contribution to patient care. Orphan drug exclusivity may also be lost if the FDA determines that the request for designation was materially defective or if the manufacturer is unable to assure sufficient quantity of the product to meet the needs of the patients with the rare disease or condition. Further, even if we obtain orphan drug designation, we may not be the first to obtain marketing approval for any particular orphan indication due to the uncertainties associated with developing pharmaceutical products.

Finally, it is unclear how future litigation, legislation, agency decisions, or administrative actions may impact the scope of the orphan drug exclusivity. We do not know if, when, or how the FDA may change the orphan drug regulations and policies in the future, and it is uncertain how any changes might affect our business. Depending on what changes the FDA may make to its orphan drug regulations and policies, our business could be adversely impacted.

We will require substantial additional capital to finance our operations, and a failure to obtain this necessary capital when needed on acceptable terms, or at all, could force us to delay, limit, reduce, or terminate our development programs, commercialization efforts or other operations.

Our operations have consumed substantial amounts of cash since inception. We expect our expenses to substantially increase in connection with our ongoing activities, particularly as we conduct our ongoing and planned clinical trials and preclinical studies and potentially seek regulatory approval for our product candidates and any future product candidates we may develop. If we obtain regulatory approval for any of our product candidates, we also expect to incur significant commercialization expenses related to product manufacturing, marketing, sales, and distribution. Because the outcome of any clinical trial or preclinical study is highly uncertain, we cannot reasonably estimate the actual amount of capital necessary to successfully complete the development and commercialization of our product candidates.

As of September 30, 2026, we had cash and cash equivalents of $124.5 million. Based on our current operating plan, we estimate that our cash and cash equivalents as of September 30, 2026 will be sufficient to fund our operating expenses and capital expenditure requirements through the end of 2028. However, we have based this estimate on assumptions that may prove to be wrong, and we could deplete our capital resources sooner than we currently expect. Our operating plans and other demands on our cash resources may change as a result of many factors currently unknown to us, and we do not expect that our existing cash and cash equivalents will be sufficient to complete development of any of our product candidates, or any future product candidates we may identify, and we will require substantial capital in order to advance our product candidates through clinical trials, regulatory approval and commercialization. Accordingly, we will need to obtain substantial additional funding in connection with our continuing operations. Our ability to raise additional funds may be adversely impacted by global economic conditions, disruptions to, and volatility in, the credit and financial markets in the United States and worldwide, and diminished liquidity and credit availability. If the equity and credit markets deteriorate, it may make any necessary debt or equity financing more difficult, more costly, and more dilutive. We cannot be certain that additional funding will be available on acceptable terms, or at all. If we are unable to raise capital when needed or on attractive terms, we could be forced to delay, reduce, or eliminate our research and development programs or any future commercialization efforts, or even cease operations. We expect to finance our cash needs through public or private equity or debt financings or other capital sources, including potential collaborations, licenses, and other similar arrangements. In addition, we may seek additional capital due to favorable market conditions or strategic considerations even if we believe we have sufficient funds for our current or future operating plans. Attempting to secure additional financing may divert our management from our day-to-day activities, which may adversely affect our ability to develop our product candidates.

•the initiation, type, number, scope, progress, expansions, results, costs and timing of preclinical studies and clinical trials of CMP-002 and any future product candidates we may choose to pursue, including the costs of modification to clinical development plans based on feedback that we may receive from regulatory authorities and any third-party products used as combination agents in our clinical trials;

•the costs and timing of manufacturing for our product candidates, including commercial manufacturing at sufficient scale, if any product candidate is approved;

•the costs, timing and outcome of regulatory meetings and reviews of our product candidates or any future product candidates, including requirements of regulatory authorities in any additional jurisdictions in which we may seek approval and any future product candidates;

•the costs associated with hiring additional personnel and consultants as our clinical and preclinical activities increase;

•the timing and payment of milestone, royalty or other payments we must make or may receive pursuant to our existing and potential future license or collaboration agreements with third parties;

•the costs and timing of establishing or securing sales and marketing capabilities if our product candidates or any product candidate is approved;

•patients’ ability and willingness to pay out-of-pocket for any approved products in the absence of coverage and/or adequate reimbursement from third-party payors;

Conducting clinical trials and preclinical studies and discovering potential product candidates using our RAP Platform is an expensive and uncertain process, and we may never generate the necessary data or results required to obtain regulatory approval and commercialize our product candidates. In addition, our product candidates, if approved, may not achieve commercial success. Our commercial revenue, if any, will initially be derived from sales of products that we do not expect to be commercially available for many years, if at all.

Risks Related to the Research and Development of Our Product Candidates

We may expend our limited resources to pursue a particular program, product candidate or indication and fail to capitalize on programs, product candidates or indications that may be more profitable or for which there is a greater likelihood of success.

Because we have limited financial and managerial resources, we focus on research programs and product candidates that we identify for specific indications that we believe can be addressed by our technology among many potential options. As a result, we may forego or delay pursuit of opportunities with other product candidates or for other indications that later prove to have greater commercial potential, or we may choose to focus our efforts and resources on a potential product candidate that ultimately proves to be unsuccessful. For example, we have received regulatory clearance to initiate our ASCEND Phase 1/2 clinical trial of CMP-002 in individuals with SYNGAP1 and expect to dose the first patient in the fourth quarter of 2026, we are advancing a preclinical program targeting SHANK3 for Phelan-McDermid syndrome, for which we expect to designate a development candidate in 2027, and we are evaluating early-stage programs for two additional haploinsufficient diseases of the CNS. We have also announced our intention to pursue partnership opportunities to support the further development of CMP-001 for individuals with urea cycle disorders. Our resource allocation decisions may cause us to fail to capitalize on viable commercial products or profitable market opportunities. Our spending on current and future research and development programs and product candidates for specific indications may not yield any commercially viable products. If we do not accurately evaluate the commercial potential or target market for a particular product candidate, we may relinquish valuable rights to that product candidate through collaboration, licensing or other royalty arrangements in cases in which it would have been more advantageous for us to retain sole development and commercialization rights to such product candidate. Any such event could have a material adverse effect on our business, financial condition, results of operations and prospects

We are early in our development efforts. Our product candidates are in varying stages of development. As a result, it will be many years before we commercialize a product candidate, if ever. If we are unable to identify and advance product candidates through preclinical studies and clinical trials, obtain marketing approval and ultimately commercialize them, or experience significant delays in doing so, our business will be materially harmed.

We are early in our development efforts and our lead product candidate has not yet entered clinical trials. We have focused our efforts to date on developing our RAP Platform, identifying our programs and commencing the preclinical and clinical development of our product candidates. Our ability to generate product revenue, which we do not expect will occur for many years, if ever, will depend heavily on the successful development and eventual commercialization of our product candidates, which may never occur. We currently generate no revenue from sales of any product, and we may never be able to develop or commercialize a marketable product.

We have received clearance from Australia’s Therapeutic Goods Administration, Argentina’s Administración Nacional de Medicamentos, Alimentos y Tecnología Médica, the United Kingdom’s Medicines and Healthcare Products Regulatory Agency and the regulatory authorities and ethics committees of six European countries to initiate our Phase 1/2 clinical trial of CMP-002 in individuals with SYNGAP1. We expect to dose the first patient in the ASCEND Phase 1/2 clinical trial in the fourth quarter of 2026. In each jurisdiction, clinical trials are subject to applicable regulatory requirements and must be reviewed and authorized by the applicable regulatory authorities and reviewed and approved by the applicable ethics committees or institutional review boards prior to initiation and as amended during the course of the trial. Commencing clinical trials in the United States is subject to acceptance by the U.S. Food and Drug Administration (the “FDA”) of an investigational new drug (“IND”) application and finalizing the trial design based on discussions with the FDA and other regulatory authorities. Commencing clinical trials outside the United States similarly requires the submission and authorization of comparable clinical trial applications or notifications, and compliance with local requirements relating to, among other things, trial conduct, informed consent, safety reporting, importation and handling of investigational product, and data integrity. In the event that the FDA or any comparable foreign regulatory authority or ethics committee requires us to complete additional preclinical studies or we are required to satisfy other requests prior to commencing clinical trials, the start of our planned ASCEND Phase 1/2 clinical trial of CMP-002 and any future clinical trials may be delayed in the relevant jurisdiction. Even after we receive and incorporate guidance from applicable regulatory authorities, such authorities could disagree that we have satisfied their requirements to commence any clinical trial or continue or change their position on the acceptability of our trial design or the clinical endpoints selected, which may require us to complete additional preclinical studies or clinical trials or impose stricter approval conditions than we currently expect, which could delay the start or completion of such clinical trials in the relevant jurisdiction or require more capital resources than we currently anticipate to start or complete such clinical trials.

Commercialization of any of our current or future product candidates will require preclinical and clinical development; regulatory and marketing approval issued by regulators in any jurisdiction where we seek to commercialize such product candidates, such as the FDA and the European Commission (the “EC”) following a favorable assessment performed by the European Medicines Agency (the “EMA”); manufacturing supply, capacity and expertise; a commercial organization; and significant marketing efforts. The success of any of our current or future product candidates will depend on many factors, including the following:

•timely and successful completion of preclinical studies;

•acceptance of INDs or comparable foreign applications that allow commencement of clinical trials or future clinical trials for any product candidates we may develop;

•successful enrollment and completion of clinical trials, including under the FDA’s current Good Clinical Practices, current Good Laboratory Practices, and any additional regulatory requirements from foreign regulatory authorities;

•positive results from our clinical trials that support a finding of safety and effectiveness and an acceptable risk-benefit profile in the intended populations;

•effectively competing against other therapies;

•acceptance of the benefits and use of our product candidates we may develop, including their method of administration, if and when approved, by patients the medical community and third-party payors; and

•maintaining a continued acceptable safety profile of our products following regulatory approval.

If we do not succeed in one or more of these factors in a timely manner or at all, we could experience significant delays or an inability to successfully commercialize any product candidates we may develop, which would materially harm our business. If we are unable to advance our product candidates into and through clinical development, obtain regulatory approval and ultimately commercialize our product candidates, or experience significant delays in doing so, our business will be materially harmed.
