Current report

Our debt obligations under the Loan and Security Agreement place restrictions on our operating and financial flexibility and could adversely affect our financial condition.

Current report

On July 30, 2026, we entered into a Loan and Security Agreement, or Loan Agreement, with Oxford Finance LLC, as collateral agent, or Collateral Agent, and certain lenders from time to time party thereto, or Lenders, providing for term loans in an aggregate principal amount of up to $200.0 million, or Term Loans. Under the terms of the Loan Agreement, the Lenders made an initial term loan of $50.0 million funded on the effective date of the Loan Agreement. Three additional tranches in an aggregate principal amount of up to $100.0 million are available upon the achievement of specified milestones and conditions related to our vonaprument and tanruprubart registrational programs, and one additional uncommitted tranche in an aggregate principal amount of up to $50.0 million is available upon the mutual agreement of the Company and the Lenders. The Term Loans bear interest at a floating per annum rate equal to the greater of (i) the 1-Month CME Term SOFR plus 4.6% and (ii) 7.60%. The Term Loans mature on July 1, 2031, or June 1, 2032, depending on the achievement of certain milestones. We are required to make monthly payments of interest only until September 1, 2029, which can be extended to September 1, 2030 or September 1, 2031, depending on the achievement of certain milestones, after which monthly payments of both principal and interest will be due. The Term Loans may be prepaid, in whole or in part, at our option, subject to customary prepayment fees. We are also obligated to pay other customary fees for a loan facility of this size and type, including a final payment fee upon repayment of the Term Loans (whether at maturity, upon acceleration or by prepayment or otherwise). We granted the Collateral Agent a security interest in substantially all of our assets to secure our obligations under the Loan Agreement.

Current report

Our debt obligations under the Loan Agreement could adversely impact us as follows:

Current report

require us to use a large portion of our cash flow to repay the outstanding principal balance, accrued and unpaid interest, prepayment fees, a final payment fee and other fees, if applicable, which will reduce the amount of cash flow available to fund working capital, capital expenditures, product candidate development and other general corporate purposes;

Current report

adversely impact our credit rating, which could increase borrowing costs and reduce our ability to raise funds on favorable terms;

Current report

subject us to restrictive covenants, including financial covenants that require us to maintain certain liquidity levels and/or minimum revenue levels upon the occurrence of certain events, that may limit our future ability to take certain corporate actions, incur additional indebtedness, create liens, make investments or pay dividends or distributions, or to raise funds for capital expenditures, strategic acquisitions or business opportunities, R&D, and other general corporate requirements;

Current report

increase our vulnerability to adverse economic, industry and market conditions; and

Current report

increase our exposure to rising interest rates from variable rate indebtedness.

Current report

Our ability to meet our payment obligations under the Loan Agreement depends on our ability to generate significant cash flows or obtain external financing in the future. This, to some extent, is subject to market, economic, financial, competitive, legislative, and regulatory factors as well as other factors that are beyond our control. There can be no assurance that our business will generate cash flow from operations, or that additional capital will be available to us, in amounts sufficient to enable us to meet our debt payment obligations and to fund other liquidity needs. Additionally, events and circumstances may occur which would cause us to not be able to satisfy applicable draw-down conditions and access the additional loan amounts available under the Loan Agreement. If we are unable to generate sufficient cash flows to service our payment obligations or satisfy our covenants under the Loan Agreement, we may need to refinance, restructure, or amend the terms of our debt, sell assets, reduce or delay capital investments, or seek to raise additional capital. If we are unable to implement one or more of these alternatives, we may be unable to meet our debt payment obligations which could result in an event of default. If we default under the Loan Agreement, the Lenders may accelerate all of our repayment obligations and exercise all of their rights and remedies under the Loan Agreement and applicable law, including foreclosing on substantially all of our assets, which secure our obligations under the Loan Agreement, potentially requiring us to renegotiate the terms of our indebtedness on terms less favorable to us. Further, if we are liquidated, the Lenders' right to repayment would be senior to the rights of the holders of our common stock to receive any proceeds from the liquidation. The Loan Agreement includes events of default, including, but not limited to, nonpayment of principal, interest, fees or other amounts; material inaccuracy of a representation or warranty; failure to perform or observe covenants; cross-defaults with certain other indebtedness; bankruptcy and insolvency events; material monetary judgment defaults; the occurrence of a material adverse change; impairment of the Lenders' security interest in the collateral; and delisting of our common stock. Upon the occurrence of an event of default (subject, in certain cases, to notice and grace periods), obligations under the Loan Agreement may be accelerated, thereby requiring us to repay the loans immediately. Any declaration by the Lenders of an event of default could significantly harm our business and prospects and could cause the price of our common stock to decline. Additionally, if we raise any additional debt financing, the terms of such additional debt could further restrict our operating and financial flexibility.

Current report

Individual states in the United States have also become increasingly active in passing legislation and implementing regulations designed to control pharmaceutical and biological product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing. For example, on June 15, 2026, the FDA approved Colorado’s Section 804 Importation Program, or SIP, proposal to import certain drugs from Canada for specific state healthcare programs. It is unclear how this and Florida’s similar program, approved by the FDA in 2024, will be implemented and whether they will overcome potential legal, regulatory, or industry challenges in the United States and/or Canada. Legally mandated price controls on payment amounts by third-party payors or other restrictions could materially and adversely affect our business, financial condition, results of operations and prospects. In addition, regional healthcare authorities and individual hospitals are increasingly using bidding procedures to determine what pharmaceutical products and which suppliers will be included in their prescription drug and other healthcare programs. This could reduce the ultimate demand for our product candidates or put pressure on our product pricing.

Current report

We will cease to be eligible to use the requirements for smaller reporting companies beginning with the Quarterly Report on Form 10-Q for the fiscal quarter ending March 31, 2027. Since we will no longer be a smaller reporting company and no longer qualify for applicable exemptions, we will be subject to additional laws and regulations affecting public companies that may increase our costs and the demands on management and could harm our operating results.

Current report

We are subject to the reporting requirements of the Exchange Act, which requires, among other things, that we file with the SEC, annual, quarterly and current reports with respect to our business and financial condition as well as other disclosure and corporate governance requirements. As a “smaller reporting company”, we take advantage of certain exemptions from disclosure requirements including not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act and reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements. Once we are no longer a smaller reporting company or otherwise qualify for these exemptions, we will be required to comply with these additional legal and regulatory requirements applicable to public companies and will incur significant legal, accounting and other expenses to do so. If we are not able to comply with the requirements in a timely manner or at all, our financial condition or the market price of our common stock may be harmed. For example, if we or our independent auditor identify deficiencies in our internal control over financial reporting that are deemed to be material weaknesses we could face additional costs to remedy those deficiencies, the market price of our stock could decline or we could be subject to sanctions or investigations by the SEC or other regulatory authorities, which would require additional financial and management resources. Because the aggregate market value of our common stock held by non-affiliates exceeded $700 million as of June 30, 2026, we will be ineligible to use the requirements for smaller reporting companies beginning with our Quarterly report on Form 10-Q for the quarter ending March 31, 2027, but will remain a non-accelerated filer through 2027. When we are no longer a “non-accelerated filer”, we will have to provide more expansive disclosure regarding executive compensation in our periodic reports and be subject to shorter filing deadlines, which will require additional time and expense. We will also be required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act.
Removed paragraphs (3)

Previous report

We may encounter substantial delays in our clinical trials or may not be able to conduct or complete our clinical trials on the timelines we expect.

Previous report

We are a “smaller reporting company,” and as a result of the reduced disclosure and governance requirements applicable to smaller reporting companies, our common stock may be less attractive to investors.

Previous report

We are a smaller reporting company and are therefore entitled to take advantage of many of the same exemptions from disclosure requirements as an emerging growth company, including reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements. In addition, as a smaller reporting company with less than $100 million in annual revenue, we are exempt from the requirement to obtain an auditor attestation on the effectiveness of our internal control over financial reporting provided in Section 404(b) of the Sarbanes-Oxley Act of 2002, or the Sarbanes-Oxley Act. These exemptions and reduced disclosures in our SEC filings due to our status as a smaller reporting company may make it harder for investors to analyze our results of operations and financial prospects.

Previous wording

We have had significant operating losses since our inception. Our net loss for the years ended December 31, 2025 and 2024 was approximately $206.7 million and $138.2 million, respectively, and our net loss for the three months ended March 31, 2026 was approximately $44.1 million. As of March 31, 2026, we had an accumulated deficit of $961.5 million. Substantially all of our losses have resulted from expenses incurred in connection with our research and development programs and from general and administrative costs associated with our operations. We expect to continue to incur losses for the foreseeable future, and we anticipate these losses will continue as we develop our product candidates, conduct clinical trials and pursue research and development activities. Even if we achieve profitability in the future, we may not be able to sustain profitability in subsequent periods. Our prior losses, combined with expected future losses, have had and will continue to have an adverse effect on our stockholders’ equity and working capital.

Previous wording

As of March 31, 2026, we had capital resources consisting of cash and cash equivalents and short-term investments of approximately $225.0 million. We expect our existing capital resources to fund planned operating expenses into the second half of 2027. However, our operating plans may change as a result of many factors currently unknown to us, and we may need to seek additional funds sooner than planned through public or private equity offerings or debt financings or other sources, such as strategic collaborations. We may also need to seek additional funds sooner than planned as result of changes in our development plans and regulatory requirements to support registration of our product candidates. Such financing may result in dilution to our stockholders, imposition of burdensome debt covenants and repayment obligations, or other restrictions that may affect our business. 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.

Additional funds may not be available when we need them, on terms that are acceptable to us, or at all. Our ability to raise additional capital may be adversely impacted by potential worsening global economic conditions, macroeconomic factors, including recent and potential bank failures, increasing inflation and interest rates, funding shortages at governmental and regulatory agencies on which we rely, exchange rate fluctuations and supply chain disruptions, geopolitical conflicts, such as the war in Ukraine and hostilities in the Middle East, and disruptions to and volatility in the credit and financial markets in the United States and worldwide. If adequate funds are not available to us on a timely basis, we may be required to:

Previous wording

For example, we intend to seek FDA approval of tanruprubart for the treatment of patients with GBS. Our data package is based on completed placebo-controlled studies conducted in Southeast Asia. We filed a MAA with the EMA for tanruprubart for the treatment of GBS in January 2026, and we continue to engage with EU regulators through the MAA review process. Tanruprubart has been granted orphan designation from the EMA. Tanruprubart has also been granted Fast Track and orphan drug designation for the treatment of GBS from the FDA. The currently ongoing open-label FORWARD study in the U.S. and Europe, which is designed to broaden Western experience with tanruprubart, and we anticipate initial PK, PD, biomarker and functional data in 2026 to supplement our comprehensive data package for tanruprubart in GBS. Following such data, we plan to engage with the FDA with the goal of reaching alignment on the sufficiency of our current and supplemental data package and information supporting the generalizability of tanruprubart in Western patients for submission of a BLA in 2026. In our discussions to date with the FDA, the FDA has indicated that the generalizability package may not be sufficient to support BLA approval absent additional patient data. While we expect that the inclusion of U.S. and European results from the FORWARD study will support a BLA submission in GBS, it is possible the FDA determines that our current package is not sufficient or requires us to provide additional data in GBS patients that are not feasible to obtain. Our inability to satisfy such additional requirements by the FDA may result in the FDA failing to approve tanruprubart in GBS, which would prevent the commercialization of tanruprubart in GBS in the United States, and limit the size of our commercial market opportunity and our potential future revenues, and could otherwise have a material adverse effect on our business.

To support data from clinical trials conducted in foreign jurisdictions, applicants may submit clinical evidence, clinical trials, patient registries or other sources of RWE, such as electronic health records or the collection of larger confirmatory data sets. In particular, because all of our studies to date for tanruprubart in GBS have been conducted at sites outside the United States, we conducted a RWE study to assess comparability of disease populations in the US and ex-US using a large natural history database from IGOS. Published data from IGOS presents baseline characteristics of GBS patients in various jurisdictions and patient outcomes at certain timepoints over the course of their disease.

Certain alternative treatments offered by competitors may be available at lower prices and may offer greater efficacy or better safety profiles. Furthermore, currently approved products could be discovered to have application for the intended indication of our product candidates, which could give such products significant regulatory and market timing advantages over any of our product candidates. Our competitors also may obtain FDA, EMA, or other regulatory approval for their products more rapidly than we may obtain approval for ours and may obtain orphan product exclusivity from the FDA for indications our product candidates are targeting, which could result in our competitors establishing a strong market position before we are able to enter the market. For example, with respect to vonaprument, there are two approved products for GA which may pose competition for vonaprument, if approved.

The availability and adequacy of coverage and reimbursement by governmental healthcare programs such as Medicare and Medicaid, private health insurers and other third-party payors are essential for most patients to be able to afford prescription medications such as our product candidates, if approved. Our ability to achieve acceptable levels of coverage and reimbursement for products by governmental authorities, private health insurers and other organizations will have an effect on our ability to successfully commercialize our product candidates. Obtaining coverage and adequate reimbursement for our products may be particularly difficult because of the higher prices often associated with drugs administered under the supervision of a physician. Even if we obtain coverage for our product candidates by a third-party payor, the resulting reimbursement payment rates may not be adequate or may require co-payments that patients find unacceptably high. For products administered under the supervision of a physician, obtaining coverage and adequate reimbursement may be particularly difficult because of the higher prices often associated with such drugs. Additionally, separate reimbursement for the product itself or the treatment or procedure in which the product is used may not be available, which may impact physician utilization. We cannot be sure that coverage and reimbursement in the United States, the EU or elsewhere will be available for our product candidates or any product that we may develop, and any reimbursement that may become available may be decreased or eliminated in the future.

Services, or HHS, imposes rebates on many Medicare Part B and Medicare Part D products to penalize price increases that outpace inflation on an annual basis. In addition, HHS has been empowered to negotiate the price of certain single-source drugs that have been on the market forat least 7 years and single-source biologics that have been on the market for at least 11 years covered under Medicare as part ofthe Medicare Drug Price Negotiation Program. Each year up to twenty (20) products will beselected by HHS for the Medicare Drug Price Negotiation Program. Products subject to the Medicare Drug Price Negotiation Program are expected to experience a significant reduction in reimbursement from the Medicare program on aper unit basis.

Third-party payors increasingly are challenging prices charged for pharmaceutical, biopharmaceutical and biotechnology products and services, and many third-party payors may refuse to provide coverage and reimbursement for particular drugs or biologics when an equivalent generic drug, biosimilar or a less expensive therapy is available.

For example, a 505(b)(2) NDA product may be for a new or improved version of the original innovator product. The Hatch-Waxman Act also provides for certain periods of regulatory exclusivity, which preclude FDA approval (or in some circumstances, FDA filing and review) of an ANDA or 505(b)(2) NDA. In addition to the benefits of regulatory exclusivity, an innovator NDA holder may have patents claiming the active ingredient, product formulation or an approved use of the drug, which would be listed with the product in the FDA publication, “Approved Drug Products with Therapeutic Equivalence Evaluations,” known as the Orange Book. If there are patents listed in the Orange Book for a product, a generic or 505(b)(2) applicant that seeks to market its product before expiration of the patents must include in their applications what is known as a “Paragraph IV” certification, challenging the validity or enforceability of, or claiming non-infringement of, the listed patent or patents. Notice of the certification must be given to the patent owner and NDA holder and if, within 45 days of receiving notice, either the patent owner or NDA holder sues for patent infringement, approval of the ANDA or 505(b)(2) NDA is stayed for up to 30 months.

In addition, in our 2023, 2024, and 2025, financings, certain of the holders of 5% or more of our capital stock acquired pre-funded warrants to purchase shares of our common stock (which are immediately exercisable and have an exercise price of $0.001 per share) or common warrants to purchase shares of our common stock. Until exercised, the shares issuable upon the exercise of the pre-funded warrants and the common warrants are not included in the number of our outstanding shares of common stock. If such holders exercise their warrants, then the shares of our capital stock beneficially owned by our executive officers, directors, holders of 5% or more of our capital stock and their respective affiliates would increase significantly. Therefore, these stockholders will have the ability to influence us through this ownership position. These stockholders may be able to determine all matters requiring stockholder approval. For example, these stockholders may be able to control elections of directors, amendments of our organizational documents, or approval of any merger, sale of assets or other major corporate transaction. This may prevent or discourage unsolicited acquisition proposals or offers for our common stock that you may feel are in your best interest as one of our stockholders.

Our current shares outstanding and resulting market valuation do not reflect shares of our common stock issuable upon the exercise of pre-funded warrants and common warrants that are exercisable at the discretion of the holders of such warrants. If we sell shares of our common stock in the future, stockholders may experience immediate dilution. Stockholders may be unable to compute the dilutive impact of future financings.

Previous wording

We may from time to time issue additional shares of common stock, and as a result, our stockholders would experience immediate dilution. In addition, as opportunities present themselves, we may enter into financing or similar arrangements in the future, including the issuance of debt securities, preferred stock or common stock. For example, in March 2024, we entered into a sales agreement with TD Cowen, as sales agent, pursuant to which we sold approximately $66.7 million of shares of our common stock under an at the market offering program as of the date of this Quarterly Report on Form 10-Q. In March 2026, we entered into a new sales agreement with TD Cowen, as sales agent, pursuant to which we may issue and sell shares of our common stock for an aggregate maximum offering price of up to $150 million under a new at-the-market offering program. In addition, in December 2023, June 2024, and November 2025, we closed financings which included the sale of pre-funded warrants or common warrants to purchase shares of our common stock. Until exercised, the shares issuable upon the exercise of the pre-funded warrants or the common warrants are not included in the number of our outstanding shares of common stock. If we issue common stock or securities convertible into common stock in the future, our stockholders would experience additional dilution and such dilutive impact may be difficult to compute.
