• Interest income decreased by $1.0 million for the three months ended September 30, 2025, and $3.1 million for the nine months ended September 30, 2025, due to decreased cash balances and lower interest rates.

Risks

• Activities to evaluate and pursue potential strategic alternatives may not result in any transaction or enhance stockholder value, and could lead to dissolution and liquidation with total loss of investment.
• The recently implemented corporate restructuring and 70% workforce reduction may not yield expected benefits, leading to loss of institutional knowledge, decreased morale, and inability to retain key employees.
• Significant operating losses since inception and anticipation of substantial operating losses for the foreseeable future, with no guarantee of achieving or maintaining profitability.
• Limited operating history and no revenue from product sales make it difficult to evaluate future viability.
• Substantial additional capital will be required to finance operations if further product development is pursued, which may not be available on acceptable terms, if at all, potentially forcing delays, reductions, or termination of programs.
• Raising additional capital may cause dilution to stockholders, restrict operations, or require relinquishing proprietary rights.
• Future success is substantially dependent on successful clinical development, regulatory approval, and commercialization of product candidates, which is uncertain.
• Strategic collaborations may require relinquishing important rights and control over product candidates.
• Success in preclinical studies or earlier clinical trials may not be indicative of future clinical trial results, and clinical trials are expensive, time-consuming, and difficult to design and implement.
• Enrollment and retention of patients in clinical trials is an expensive and time-consuming process and could be delayed or rendered impossible by factors outside control.
• The manufacture of product candidates is complex and uncertain, and difficulties in supplying future clinical trials or meeting quality standards could impact timelines and development strategy.
• Product candidates may cause undesirable side effects or have other properties that could delay or prevent regulatory approval, limit commercial potential, or result in negative consequences post-marketing approval.
• Inability to obtain or maintain orphan drug designations or exclusivity could limit potential profitability.
• Even if product candidates receive marketing approval, they may fail to achieve market acceptance.
• Substantial competition from major pharmaceutical and biotechnology companies.
• Dependence on collaboration with Everest for zetomipzomib in certain regions, with risks if Everest fails to perform.
• Relationships with healthcare professionals and third-party payors are subject to federal and state healthcare fraud and abuse laws, transparency laws, false claims laws, and health information privacy and security laws, with potential for substantial penalties for non-compliance.
• Reliance on third parties to manufacture clinical supplies and conduct clinical trials, with risks if they perform unsatisfactorily.
• Licensing of intellectual property is critical, and breach of the Onyx License Agreement could lead to loss of rights to zetomipzomib.
• Inability to obtain and maintain broad or long-lasting patent protection for product candidates.
• Patent terms may be inadequate to protect competitive position for an adequate amount of time.
• High dependence on executive officers, and inability to retain or recruit key personnel could harm the business.
• Thinly traded common stock, making it difficult for stockholders to sell quickly or at market price.
• Concentration of ownership among existing executive officers, directors, and principal stockholders may prevent new investors from influencing significant corporate decisions.
• No anticipated cash dividends, making capital appreciation the sole source of gain.
• As a smaller reporting company, reduced disclosure requirements may make common stock less attractive to investors.
• Increased costs and management time devoted to new compliance initiatives as a public company.
• Provisions in corporate charter documents and Delaware law could make an acquisition more difficult and prevent attempts by stockholders to replace management.
• Exclusive forum provisions in the corporate charter could limit stockholders' ability to obtain a favorable judicial forum.
• Unstable market and economic conditions, including inflation, interest rate changes, and geopolitical tensions, may have serious adverse consequences.

Future Outlook

The company is exploring a full range of strategic alternatives to maximize stockholder value, which may include mergers, acquisitions, partnerships, or even dissolution and liquidation. Research and development and general and administrative expenses are expected to remain flat or decrease for the remainder of 2025 due to the suspension of various development efforts and the recent workforce reduction. Interest expense is also expected to decrease for the remainder of 2025 following the full repayment of the loan. The company believes its existing cash, cash equivalents, and marketable securities will be sufficient to fund cash requirements for at least 12 months from the financial statements' issuance date.

Management Comments

• Management believes that its existing cash, cash equivalents and marketable securities will be sufficient to fund the Company’s cash requirements for at least 12 months following the issuance of these financial statements.
• If the process for evaluating strategic alternatives does not result in the Company consummating a transaction or any other strategic outcome, the Board of Directors may decide to pursue a dissolution and liquidation of the Company.
• Failure to manage discretionary spending during this time may adversely impact the Company’s ability to achieve its intended business objectives.
• There can be no assurance that this strategic review process will result in us pursuing any transaction or that any transaction, if pursued, will be completed on attractive terms or at all.
• Additionally, there can be no assurances that any particular course of action, business arrangement or transaction, or series of transactions, will be pursued, successfully consummated or lead to increased stockholder value or that we will make any additional cash distribution to our stockholders.
• Due to the suspension of various development efforts related to our programs and the recent reduction in our workforce, we expect our research and development expenses to remain flat or decrease for the remainder of 2025.
• As a result of the ongoing strategic review and workforce reduction, we expect that our general and administrative expenses will remain flat or decrease for the remainder of 2025.
• As a result, we expect the interest expense to decrease for the remainder of 2025.

Industry Context

The biotechnology industry is highly competitive and capital-intensive, with significant risks associated with clinical development and regulatory approval. Kezar's decision to explore strategic alternatives and reduce its workforce reflects the challenges faced by clinical-stage companies when product candidates fail to meet regulatory alignment or demonstrate sufficient differentiation. The termination of trials and inability to align with the FDA on a registrational study for AIH highlight the high-risk nature of drug development, where even promising early-stage data does not guarantee success. The focus on cost containment and liquidity management is a common response in such situations, aiming to preserve value while seeking a new strategic direction.

Comparison to Industry Standards

• The company's accumulated deficit of $476.0 million and ongoing operating losses are typical for clinical-stage biotechnology companies that have not yet commercialized a product, similar to many early-to-mid stage biotechs focused on R&D.
• The significant reduction in R&D expenses (e.g., $21.0 million decrease for YTD Sep 2025 vs. YTD Sep 2024) is a drastic measure, often seen in companies undergoing significant strategic shifts or facing clinical setbacks, contrasting with companies like Vertex Pharmaceuticals or Regeneron Pharmaceuticals that maintain high R&D spending due to successful pipelines.
• The 70% workforce reduction is a severe measure, indicative of a company in a distressed state or undergoing a major pivot, far exceeding typical workforce adjustments in stable or growing biotech firms.
• The inability to align with the FDA on a registrational trial for zetomipzomib in AIH, despite positive Phase 2a results, underscores the stringent and often unpredictable nature of FDA requirements, a common hurdle for many drug developers, such as those experienced by companies like Acadia Pharmaceuticals with their neurological drug candidates or smaller biotechs attempting to navigate complex regulatory pathways.
• The exploration of strategic alternatives, including potential dissolution, is a common outcome for biotech companies whose lead programs fail to advance, a path taken by numerous small biotechs that run out of viable pipeline assets or funding.

Management Changes

Corporate Governance

Legal Proceedings

• Not currently a party to any material legal proceedings.
• Not aware of any pending or threatened legal proceeding that could have an adverse effect on business, operating results, or financial condition.

Stakeholder Impact

• Shareholders: High uncertainty regarding future value, potential for dilution if equity financing is pursued, or total loss of investment if dissolution occurs. The stock price is likely to be volatile.
• Employees: Significant impact due to a 70% workforce reduction, leading to job losses and potential morale issues for remaining staff.
• Customers/Patients: Development of product candidates (zetomipzomib, KZR-261) has been halted or significantly delayed, impacting potential future treatments for immune-mediated diseases.
• Creditors: The $6.3 million loan from Oxford Finance was fully repaid, reducing immediate debt obligations.
• Suppliers/Partners: Collaboration with Everest continues, but the termination of key trials and strategic review may impact future engagements or the scope of existing partnerships.

Next Steps

• Continue exploring a full range of strategic alternatives focused on maximizing stockholder value.
• Manage cash expenditures related to the approximately $6.0 million for workforce reduction costs, primarily in Q4 2025.
• Evaluate the impact of ASU 2024-03 and ASU 2023-09 on financial statements and disclosures.
• Conduct a stand-alone study to define the pharmacokinetics of zetomipzomib in subjects with significant hepatic impairment, if further AIH development is pursued.
• Potentially pursue a dissolution and liquidation of the company if strategic alternatives do not result in a consummated transaction.

Key Dates

Recommendation

The company is in a highly precarious position, having terminated multiple clinical programs, failed to align with the FDA on a registrational trial for its lead candidate (zetomipzomib in AIH), and implemented a drastic 70% workforce reduction. The explicit mention of exploring strategic alternatives, including potential dissolution and liquidation, signals a high probability of significant shareholder value impairment or complete loss. While the company has some cash, its burn rate and lack of a clear path forward for its pipeline make the investment extremely risky. The extension of the Rights Plan might deter hostile takeovers but does not address the fundamental business challenges.
