Risks

• The company has a limited operating history, no products approved for commercial sale, and anticipates incurring substantial and increasing losses for the foreseeable future.
• Substantial additional financing will be required to achieve goals, and failure to obtain capital on acceptable terms could delay, limit, reduce, or terminate product development or commercialization efforts.
• Preclinical and clinical development is a lengthy, expensive, and uncertain process, and earlier trial results may not predict future outcomes.
• Clinical trials may reveal serious adverse events (SAEs) and significant adverse events (AEs) not previously seen, potentially delaying or preventing regulatory approval or market acceptance.
• The company faces significant competition from large and specialty pharmaceutical and biotechnology companies with greater resources and approved therapies.
• Various risks are related to the ACELYRIN acquisition, including integration challenges, personnel retention, and unforeseen liabilities.
• The business is highly dependent on the success of envu, and there is no guarantee it will successfully complete development, receive regulatory approval, or be commercialized.
• Regulatory approval processes are lengthy, time-consuming, and inherently unpredictable, potentially leading to delays or denial of approval.
• Dependence on the management team and other clinical and scientific personnel, with risks if these individuals cannot be retained or new ones recruited.
• Inability to obtain and maintain sufficient intellectual property protection for product candidates could allow competitors to commercialize similar products.
• Patent rights relating to inventions in pending applications may not issue, or issued patents may be challenged and rendered invalid/unenforceable.
• Conflicts with current or future licensors or collaborators could delay or prevent development or commercialization.
• Ongoing regulatory obligations and review post-approval could result in significant additional expense, labeling restrictions, or market withdrawal.
• International trade policies, including tariffs, sanctions, and trade barriers, may adversely affect business, financial condition, results of operations, and growth prospects.
• The future impairment of IPR&D intangible assets related to the ACELYRIN Merger may negatively affect results of operations and financial position.
• The company's operations are predominantly concentrated in one location (California), making it vulnerable to natural disasters.
• Cash and cash equivalents may be exposed to failure of banking institutions, as seen with SVB and Signature Bank.
• A federal securities class action lawsuit against ACELYRIN was assumed by the company, which could result in substantial damages or other expenses and divert management's time.

Future Outlook

The company expects to continue incurring significant and increasing expenses and substantial losses for the foreseeable future as it advances product candidates through clinical trials, seeks regulatory approvals, expands its product pipeline, and integrates the acquired ACELYRIN business. Profitability depends on successful development, approval, and commercialization of product candidates and achieving sufficient revenue. The company anticipates needing substantial additional funding to support ongoing research and development and future operations, which may involve public or private equity, debt financings, strategic alliances, or licensing arrangements. Delays or discontinuations of development programs may occur if capital is not available on favorable terms.

Management Comments

• Our mission is to significantly improve the lives of patients by replacing broad immunosuppression with targeted therapies.
• We expect to continue to incur substantial losses for the foreseeable future, and its ability to achieve and sustain profitability will depend on the successful development, approval, and commercialization of any product candidates it may develop, and on the achievement of sufficient revenue to support its cost structure.
• The Company believes that, based on its current operating plan, its existing cash, cash equivalents and marketable securities of $377.7 million as of September 30, 2025, will be sufficient to meet its operating and capital requirements for at least 12 months from the date of issuance of these unaudited condensed consolidated financial statements.
• We are continuing to evaluate the development program for lonigutamab and its potential differentiation in a capital efficient manner.

Industry Context

Alumis operates in the highly competitive biopharmaceutical industry, focusing on autoimmune disorders. The company's strategy involves leveraging a precision data analytics platform and expertise in immunology to develop targeted therapies, moving away from broad immunosuppression. The acquisition of ACELYRIN and its lead candidate, lonigutamab, reflects a trend of consolidation and pipeline expansion within the sector. The ongoing development of TYK2 inhibitors (envu, A-005) places Alumis in a competitive landscape with other companies developing similar mechanisms, such as deucravacitinib (Sotyktu). The industry faces increasing scrutiny over drug pricing and reimbursement, as well as evolving regulatory frameworks in the U.S. (e.g., IRA, OBBBA) and internationally (e.g., EU CTR, HTA Regulation), which could impact market access and profitability.

Comparison to Industry Standards

• Alumis's lead candidate, envu, a TYK2 inhibitor, is in Phase 3 for plaque psoriasis, competing with approved therapies like deucravacitinib (Sotyktu). The filing notes that deucravacitinib has shown adverse events such as hypersensitivity reactions, infections, malignancy, and rhabdomyolysis, and includes a warning for JAK-related AEs. Alumis's envu has observed AEs including headaches, upper respiratory tract infections, nasopharyngitis, rash, and nausea, with four SAEs (one serious infection, two malignancies, one arthritis case) considered related by the investigator in the STRIDE OLE trial. The comparison of safety profiles will be critical for market differentiation.
• The discontinuation of envu's Phase 2a trial in non-infectious uveitis due to insufficient efficacy, despite a consistent safety profile, highlights the inherent risks and high failure rates common in biopharmaceutical development, aligning with industry challenges where promising early-stage candidates often fail in later stages.
• The ACELYRIN merger, which brought lonigutamab (targeting IGF-1R for TED), positions Alumis against the sole currently-approved therapy in the United States for TED. Lonigutamab's potential to improve on safety and side-effect profile is unproven, and ACELYRIN observed AEs like headache, tinnitus, and injection site reactions in its Phase 2 trial, which are important considerations for competitive positioning against existing treatments.

Corporate Governance

Legal Proceedings

• A federal securities class action lawsuit (Boukadoum v. Acelyrin, Inc. et al., No. 2:23-cv-09672-FMO-MAA) was commenced on November 15, 2023, against ACELYRIN and its then-current and former executive officers and directors. The complaint alleges violations of the Exchange Act and Securities Act by misleading investors about the Phase 2b trial of izokibep in hidradenitis suppurativa. The company assumed these liabilities in the ACELYRIN Merger. A motion to dismiss the amended complaint, filed on March 26, 2024, remains pending. The company is currently unable to estimate the possible loss, which could be material.

Related Party Transactions

• The company has a services agreement with Foresite Labs, LLC, an affiliate of Foresite Capital Management (a stockholder). Foresite Labs provides services to assist in exploring specified immunology genetic targets. For the three and nine months ended September 30, 2025, the company recognized $0.3 million and $0.8 million, respectively, as research and development expenses under this agreement.

Stakeholder Impact

• Shareholders face potential dilution from future capital raises and stock price volatility due to the company's early stage, ongoing losses, and the inherent risks of drug development. The concentration of ownership by principal stockholders and management (approximately 40% of voting stock) may limit the influence of other stockholders.
• Employees, particularly those from ACELYRIN, were impacted by severance costs and accelerated vesting of equity awards related to the merger. The company's ability to attract and retain highly qualified management, clinical, and scientific personnel is crucial for its success.
• Patients stand to benefit from the potential development of transformative medicines for autoimmune disorders, but also face the risks of clinical trial failures, adverse events, and delays in product availability.
• Suppliers, CROs, and CMOs are critical to the company's operations, and any disruptions in their performance, compliance, or supply chain could significantly impact development timelines and costs.
• Creditors are exposed to the company's substantial and increasing operating losses and its ongoing need for additional capital to fund operations, which could affect its ability to meet financial obligations.
• Regulatory bodies will continue to scrutinize the company's clinical trials, manufacturing processes, and compliance with evolving healthcare laws, potentially imposing restrictions or penalties.

Next Steps

• Report topline results for the Phase 3 ONWARD clinical program of envu in plaque psoriasis early in the first quarter of 2026.
• Report topline results for the Phase 2 clinical trial of envu in systemic lupus erythematosus in the third quarter of 2026.
• Continue to evaluate the development program for lonigutamab and its potential differentiation in a capital efficient manner.
• Continue to progress the development of product candidates in multiple clinical trials in parallel.
• Explore additional indications for existing product candidates.
• Obtain, maintain, expand, and protect intellectual property rights.
• Make royalty, milestone, or other payments under existing or future license/collaboration agreements.
• Identify, acquire, or in-license new technologies or product candidates.
• Seek regulatory and marketing approvals for product candidates that successfully complete clinical trials.
• Procure manufacturing and supply chain capacity for product candidates, including commercial manufacturing readiness and scale-up.
• Add operational, legal, financial, and management information systems and personnel to support product development, clinical execution, and planned future commercialization efforts.
• Establish a sales, marketing, and distribution infrastructure to commercialize any approved product candidates.
• Address the pending motion to dismiss in the federal securities class action lawsuit against ACELYRIN.

Key Dates

Recommendation

Alumis Inc. is a clinical-stage biopharmaceutical company with a high-risk, high-reward profile. While the ACELYRIN merger provided a significant one-time gain and expanded the pipeline with lonigutamab, it also introduced integration costs and legal liabilities. The company's lead candidate, envu, is progressing to Phase 3 for plaque psoriasis, which is a positive development, but another trial for uveitis was discontinued due to efficacy concerns. Operating expenses and cash burn have increased substantially, and the company explicitly states a need for significant additional capital in the future, despite current liquidity being sufficient for 12 months. The inherent uncertainties of drug development, intense competition, and regulatory complexities, coupled with the pending securities lawsuit, suggest a 'hold' recommendation. Investors should monitor clinical trial results, progress on lonigutamab, and future financing activities closely before making further investment decisions.
