"We were deeply saddened to learn that the patient who experienced Grade 4 liver transaminase elevations and increased total bilirubin following a dose of nex-z in the MAGNITUDE Phase 3 clinical trial, as reported on October 27, 2025, passed away last night," said Intellia President and Chief Executive Officer John Leonard, M.D. "We have been advised by the treating physician that this is a case with complicating comorbidities, and it is being further evaluated. As we await the FDA’s clinical hold letter, we are working with clinical investigators and external experts to better understand the liver-related events that have been observed within MAGNITUDE and to develop our risk mitigation plan."

"We continue to believe in nex-z’s potential to address important unmet needs for patients with ATTR amyloidosis," Dr. Leonard continued. "Regarding our other late-stage investigational product for the treatment of HAE, lonvo-z, we have made considerable progress over the course of 2025. Enrollment was completed in the HAELO Phase 3 clinical trial of lonvo-z in September, less than nine months after we dosed our first patient in the trial, putting us on track to share topline data by mid-2026. We look forward to presenting longer-term data from our Phase 1/2 clinical trial of lonvo-z on Saturday at ACAAI."

Recent Updates About Nexiguran Ziclumeran (nex-z) for Transthyretin (ATTR) Amyloidosis

Nex-z is an investigational in vivo CRISPR-based therapy designed to inactivate the TTR gene in the liver, thereby preventing the production of transthyretin (TTR) protein. Nex-z offers the possibility of halting and reversing disease by driving a deep, consistent and potentially lifelong reduction in TTR protein after a single dose. Intellia leads the development and commercialization of nex-z in collaboration with Regeneron Pharmaceuticals, Inc.

On October 29, 2025, the U.S. Food and Drug Administration (FDA) placed a clinical hold on the Investigational New Drug applications for the MAGNITUDE and MAGNITUDE-2 Phase 3 clinical trials for patients with ATTR amyloidosis with cardiomyopathy (ATTR-CM) and hereditary ATTR amyloidosis with polyneuropathy (ATTRv-PN), respectively.

More than 650 patients with ATTR-CM are currently enrolled in MAGNITUDE, and 47 patients with ATTRv-PN are enrolled in MAGNITUDE-2. To date, Grade 4 liver transaminase elevations have been reported in less than one percent of all patients enrolled in MAGNITUDE and no Grade 4 liver transaminase elevations have been reported in MAGNITUDE-2.

Intellia recently mandated that all MAGNITUDE and MAGNITUDE-2 clinical sites increase their monitoring of patient laboratory values in the weeks after dosing. The company continues to consult with clinical investigators and other experts to investigate the transaminase elevations and consider potential additional risk mitigation strategies while awaiting the FDA’s formal clinical hold letter. Given the clinical hold, the company has suspended its milestone guidance for nex-z pending regulatory alignment. Intellia plans to provide an update after it has finalized a plan with regulators on the path forward.

Sana announced it will prioritize future development activity for SC451, a HIP-modified stem cell-derived pancreatic islet cell therapy for type 1 diabetes, and for SG293, an in vivo CAR T with CD8-targeted fusogen delivery of a CD19-directed CAR. The company continues to see meaningful progress in its type 1 diabetes program, particularly in advancing SC451 toward an IND. In addition, Sana improved the potency and manufacturability of its next-generation in vivo CAR T product platform, and the company is incorporating these updates into SG293 and expects to file an IND for this program as early as 2027. The company has suspended development of its two allogeneic cell therapy CAR T programs – SC291 in B-cell mediated autoimmune diseases and SC262 in oncology.

"Given our recent progress and the potentially transformative impact with SC451 in type 1 diabetes, as well as with our in vivo CAR T platform across a range of diseases, now is the time to concentrate our efforts in these programs," said Steve Harr, President and CEO of Sana. "Our goal for SC451 in type 1 diabetes is a single treatment leading to normal blood glucose with no need for further insulin treatment or immunosuppression, and the past several quarters of clinical results, manufacturing progress, and regulatory developments have solidified our confidence that this is possible. Additionally, as we progress toward our goals of filing an IND and beginning our Phase 1 clinical trial next year, we believe now is the time to free up resources to invest in scaling this important therapy. Separately, we have increased the potency of in vivo CAR T platform, and based upon preclinical data, believe we have the opportunity to develop best-in-class therapies with a single treatment and no conditioning chemotherapy for a range of B-cell cancers and B-cell mediated autoimmune diseases. Based upon our momentum and given the resources required to fully exploit these opportunities, we have made the difficult decision to suspend our allogeneic CAR T programs, including SC291 and SC262. While these programs increased our confidence in our HIP platform, we believe the impact we can have for patients and shareholders is now greater with increased focus on SC451 and in vivo CAR T cells."

Recent Corporate Highlights

Published positive results from an investigator-sponsored, first-in-human study transplanting UP421, an allogeneic primary islet cell therapy engineered with hypoimmune platform (HIP) technology, into a patient with type 1 diabetes without the use of any immunosuppression.

UP421 is a primary human HIP-modified pancreatic islet cell therapy for patients with type 1 diabetes. The goal of this investigator-sponsored trial (IST) is to understand safety, immune evasion, islet cell survival, and beta cell function, as measured by C-peptide production, of HIP-modified pancreatic islet cells transplanted into type 1 diabetes patients without the use of any immunosuppression. The trial is being conducted under a clinical trial authorization at Uppsala University Hospital with Dr. Per-Ola Carlsson as the principal investigator.
Results of the study through 6 months after cell transplantation demonstrate the survival and function of pancreatic beta cells as measured by the presence of circulating C-peptide, a biomarker indicating that transplanted beta cells are producing insulin. C-peptide levels also increase with a mixed meal tolerance test at these timepoints, consistent with insulin secretion in response to a meal. 12-week PET-MRI scanning demonstrated islet cells at the transplant site. The study identified no safety issues, and the HIP-modified islet cells evaded immune detection.
The New England Journal of Medicine (NEJM) published a journal article titled "Survival of Transplanted Allogeneic Beta Cells with No Immunosuppression" (DOI: 10.1056/NEJMoa2503822). The article discusses 12-week results from this study. NEJM also published an accompanying editorial that further describes both the Sana technology and progress in the field (DOI: 10.1056/NEJMe2507578).
Sana and Uppsala University Hospital expect to report additional data from the IST, including longer-term follow-up.
Advancing our focused pipeline across two platforms:

Hypoimmune Platform – Type 1 diabetes – Sana continues pre-clinical development of SC451, an O-negative, HIP-modified, iPSC-derived pancreatic islet cell therapy, which uses the same HIP technology as UP421. Sana has had multiple interactions with regulators over the past several months, including an FDA INTERACT meeting, the results of which increase confidence in moving forward with our HIP-edited master cell bank for GMP manufacturing and our nonclinical testing plan. Sana expects to file an IND and begin our Phase 1 clinical trial for SC451 as early as 2026.
Fusogen Platform – In vivo CAR T cells – SG293 is the next-generation version of our prior SG299 product candidate and was renamed to reflect an updated construct and manufacturing process. SG293 is a CD8-targeted fusosome that delivers to CD8+ T cells the genetic material to make CD19-directed CAR T cells while avoiding potentially troublesome delivery to tissues such as the liver. SG293 builds on data from SG299, showing cell-specific delivery and deep B-cell depletion – as measured by depletion in circulating and lymph node B cells as well as a phenotypic reset when B cells return – in non-human primates without the use of any lymphodepleting chemotherapy. Sana intends to explore SG293 in both B-cell cancers and B-cell mediated autoimmune diseases. The company expects to file an IND for SG293 as early as 2027.
SC291 (HIP-modified CD19-directed allogeneic CAR T) in autoimmune diseases and SC262 (HIP-modified CD22-directed allogeneic CAR T) in oncology – Sana recently published in the journal Cell Stem Cell an article titled "Hypoimmune CD19 CAR T cells evade allorejection in patients with cancer and autoimmune disease," which provides additional clinical data showing how HIP-modified cells avoid immune attack (doi.org/10.1016/j.stem.2025.07.009). Nevertheless, as the company seeks to further prioritize resources and follow promising data in the SC451 and fusogen programs, Sana has suspended enrollment and further internal investment in the respective Phase 1 trials.
Raised aggregate gross proceeds of $133.2 million from sales of common stock through Sana’s at-the-market offering facility (ATM) and equity financing in the third and fourth quarters of 2025; expected cash runway into late 2026.

Closed public offering in August 2025 of 24.3 million shares of Sana’s common stock, including 3.4 million shares pursuant to the full exercise of the underwriters’ option to purchase additional shares, and pre-funded warrants to purchase 1.5 million shares of Sana’s common stock. The gross proceeds from this offering were $86.3 million before deducting underwriting discounts and commissions and offering expenses.
Raised gross proceeds of $29.5 million in the third quarter of 2025 and an additional $17.4 million in the fourth quarter of 2025 from sales of common stock through Sana’s ATM.
Third Quarter 2025 Financial Results

GAAP Results

Cash Position: Cash, cash equivalents, and marketable securities as of September 30, 2025 were $153.1 million compared to $152.5 million as of December 31, 2024. The increase of $0.6 million was primarily driven by net proceeds from equity financings of $109.7 million and other cash inflows of $2.4 million, partially offset by cash used in operations of $111.2 million.
Research and Development Expenses: For the three and nine months ended September 30, 2025, research and development expenses, inclusive of non-cash expenses, were $30.1 million and $97.1 million, respectively, compared to $53.2 million and $170.5 million for the same periods in 2024. The decreases of $23.1 million and $73.5 million for the three and nine months ended September 30, 2025 compared to the same periods in 2024, respectively, were primarily due to the portfolio prioritization announced in the fourth quarter of 2024, which resulted in lower research, laboratory, and clinical development costs, lower personnel-related costs, including non-cash stock-based compensation, and a decrease in facility and other allocated costs. Research and development expenses include non-cash stock-based compensation of $3.2 million and $12.0 million, respectively, for the three and nine months ended September 30, 2025, and $6.5 million and $19.5 million for the same periods in 2024.
Research and Development Related Success Payments and Contingent Consideration: For the three and nine months ended September 30, 2025, Sana recognized non-cash expenses of $3.1 million and $15.3 million, respectively, compared to a non-cash gain of $5.5 million and a non-cash expense of $4.6 million for the same periods in 2024, in connection with the change in the estimated fair value of the success payment liabilities and contingent consideration in aggregate. The value of these potential liabilities fluctuates significantly with changes in Sana’s market capitalization and stock price.
General and Administrative Expenses: General and administrative expenses for the three and nine months ended September 30, 2025, inclusive of non-cash expenses, were $10.3 million and $32.1 million, respectively, compared to $14.1 million and $46.8 million for the same periods in 2024. The decreases of $3.8 million and $14.7 million for the three and nine months ended September 30, 2025, respectively, compared to the same periods in 2024 were primarily due to lower personnel-related costs, including non-cash stock-based compensation, due to a decrease in headcount in connection with the portfolio prioritization announced in the fourth quarter of 2024, and decreased legal and consulting fees. General and administrative expenses include non-cash stock-based compensation of $2.3 million and $7.1 million for the three and nine months ended September 30, 2025, respectively, compared to $4.3 million and $11.8 million for the same periods in 2024.
Impairment of Long-Lived Assets: For the nine months ended September 30, 2025, non-cash impairment of long-lived assets was $44.6 million, compared to zero for the same period in 2024. The non-cash impairment, recorded in the second quarter of 2025, was primarily related to Sana’s manufacturing facility in Bothell, Washington and certain laboratory and office space in Seattle, Washington. Because of the increased availability of manufacturing capacity at third-party contract development and manufacturing organizations (CDMOs) for cell and gene therapy products as well as progress in understanding its near-term manufacturing needs, Sana expects to use CDMOs to meet its manufacturing needs at present and has suspended further build-out of internal manufacturing capabilities.
Net Loss: Net loss for the three and nine months ended September 30, 2025 was $42.2 million, or $0.16 per share, and $185.3 million, or $0.75 per share, respectively, compared to $59.9 million, or $0.25 per share, and $217.7 million, or $0.95 per share, for the same periods in 2024.
Non-GAAP Measures

Non-GAAP Operating Cash Burn: Non-GAAP operating cash burn for the nine months ended September 30, 2025 was $108.0 million compared to $153.1 million for the same period in 2024. Non-GAAP operating cash burn is the decrease in cash, cash equivalents, and marketable securities, excluding cash inflows from financing activities, costs related to the portfolio prioritizations in the fourth quarters of 2024 and 2023, and the purchase of property and equipment.
Non-GAAP Net Loss: Non-GAAP net loss for the three and nine months ended September 30, 2025 was $39.0 million, or $0.15 per share, and $125.4 million, or $0.51 per share, respectively, compared to $64.7 million, or $0.27 per share, and $208.3 million, or $0.91 per share, for the same periods in 2024. Non-GAAP net loss excludes non-cash expenses and gains related to the change in the estimated fair value of contingent consideration and success payment liabilities, and non-cash impairment losses recorded in 2025.

"Following constructive feedback from the FDA, we are working to finalize our SER-155 Phase 2 study protocol for the prevention of bloodstream infections in adults undergoing allogeneic hematopoietic stem cell transplant (allo-HSCT) for hematological malignancies," said Thomas DesRosier and Marella Thorell, co-Chief Executive Officers of Seres. "As we prepare for the next phase of SER-155 development, we continue our efforts aimed at securing the funding needed to conduct the Phase 2 study. We expect to be ready to rapidly operationalize the study once financing is in place, and we expect to obtain interim efficacy and safety results within 12 months of the study start. If these results are consistent with our prior successful Phase 1b study, and supportive of continued development, we believe this milestone should be a significant value-creating event for the Company and shareholders. Based on our on-going engagement with the medical community and assessment of the commercial landscape, we remain highly enthusiastic about the broad potential for SER-155—in allo-HSCT and other medically vulnerable populations."

Mr. DesRosier and Ms. Thorell continued, "In addition to SER-155 development in allo-HSCT, we are expanding our understanding of the broader SER-155 therapeutic opportunity through an ongoing investigator-sponsored study in immune checkpoint related enterocolitis, initiated by the investigator at Memorial Sloan Kettering Cancer Center, and we look forward to obtaining initial efficacy results in early 2026. Additionally, during the third quarter, we implemented cost-reduction measures, including decreasing our workforce. Considering these actions and our current operating plans, we expect to fund operations through the second quarter of 2026, providing flexibility to advance our strategic priorities."

Recent Highlights

SER-155 and Bloodstream Infection (BSI) Prevention

•
Efforts are ongoing to obtain capital and other resources to support the SER-155 Phase 2 study. The Company is evaluating a range of potential deal structures that could leverage Seres’ live biotherapeutics expertise and success, as demonstrated by bringing VOWST, the first FDA-approved oral microbiome therapeutic, from early development through FDA approval.

•
The Company received constructive feedback from the FDA during the third quarter and is working to finalize the planned Phase 2 study protocol for SER-155 in allo-HSCT, which previously received Breakthrough Therapy designation. The study is expected to enroll approximately 248 participants and incorporate an adaptive design and an interim data analysis when approximately half of the enrolled participants have reached the primary endpoint. The Company expects to obtain the interim clinical results within 12 months following study initiation, which it believes will facilitate timely engagement with the FDA on the design of a Phase 3 study, and inform development in adjacent medically vulnerable patient populations. The Company believes that positive results from the Phase 2 study, if achieved, could create significant value and enable advancement into a single Phase 3 trial to support registration.

•
In the third quarter, CARB-X (Combating Antibiotic-Resistant Bacteria Biopharmaceutical Accelerator), a global non-profit partnership accelerating antibacterial products to address drug-resistant bacteria, awarded Seres a grant of up to $3.6 million, representing the second grant the Company has received from CARB-X. The funds will support the development of an oral liquid formulation of SER-155, potentially expanding patient access for medically vulnerable populations who cannot be dosed with oral capsules.

•
In October, Seres presented an oral presentation at IDWeek 2025. The presentation included new post-hoc analysis from the completed SER-155 Phase 1b study describing differences between the SER-155 and placebo groups, including the bacterial and fungal organisms causing BSIs, BSI event clinical outcomes, antibacterial prophylaxis use, and patterns of antimicrobial resistance (AMR) among the bacterial BSI organisms. These new data illustrated that BSIs occurred despite antibacterial prophylaxis, and that BSI bacteria exhibited AMR. Resistance to multiple antibacterial agents was observed only in the BSI bacteria from placebo-treated participants, two of whom had fatal outcomes related to their BSIs. These new data further support the potential of SER-155 as an innovative alternative approach to the significant unmet medical need for prevention of BSIs in HSCT patients, especially those BSIs associated with AMR that increase the risk of morbidity and mortality.

Development of Biotherapeutics for the Treatment of Inflammatory and Immune Diseases

•
The Company is collaborating with Memorial Sloan Kettering Cancer Center on an investigator-sponsored trial (IST) which is evaluating SER-155 in participants with immune checkpoint related enterocolitis (irEC). Enrollment is anticipated to be completed by the end of 2025, with clinical readout expected in early 2026. IrEC is among the most frequent and severe immune-related adverse events (irAEs) in recipients of immune checkpoint-inhibitor therapy and can be observed in up to 50% of patients, with rates varying based on cancer drug and treatment regimen. Immune checkpoint inhibitors can cause a wide range of irAEs with links to T cell biology and epithelial barrier inflammation, both of which are biological functions shown in our preclinical and clinical pharmacology data to be positively impacted by SER-155. Supportive data from this IST could provide further support for the expansion of indications that may be well suited for our biotherapeutic approach.

•
Seres continues to explore potential R&D partnerships to advance development of its investigational live biotherapeutics in inflammatory and immune diseases, including ulcerative colitis and Crohn’s disease.

Financial Results

The Company has classified all historical operating results for the VOWST business within discontinued operations in the consolidated statements of operations for the comparative periods presented (three and nine months ended September 30, 2024). There is no activity in the current period related to discontinued operations.

•
Seres reported net income from continuing operations of $8.2 million for the third quarter of 2025, as compared to a net loss from continuing operations of $51.0 million for the same period in 2024. The net income of $8.2 million is comprised primarily of a $22.5 million loss from operations offset by a $27.2 million gain on sale of VOWST resulting primarily from the $25 million installment payment received, as expected, from Nestle during the third quarter. The net loss of $51.0 million in 2024 is primarily comprised of a $29.2 million loss from operations plus a $23.4 million loss on the extinguishment of the Oaktree debt, which was retired at completion of the VOWST sale in September 2024.

•
Research and development (R&D) expenses for the third quarter of 2025 were $12.6 million, compared with $16.5 million for the third quarter of 2024. The decrease in R&D expenses was primarily driven by a decrease in personnel and related costs, a decrease in platform investments, and a reduction in clinical expenses resulting from completion of the SER-155 Phase 1b study.

•
General and administrative (G&A) expenses for the third quarter of 2025 were $9.5 million, compared with $12.7 million for the third quarter of 2024. The decrease in G&A expenses was primarily a result of lower personnel and related expenses, including IT-related expenses.

•
Manufacturing services expenses were $0.7 million for the third quarter of 2025. These costs relate to the provision of manufacturing services under the Transition Services Agreement (TSA) with Nestlé, which began in the fourth quarter of 2024. The reimbursement received from Nestlé related to these expenses is recognized in other income.

Cash Runway

As of September 30, 2025, Seres had $47.6 million in cash and cash equivalents. Based on the Company’s current cash position, VOWST transaction-related obligations, and current operating plans, the Company expects to fund operations through the second quarter of 2026. The Company continues to evaluate further opportunities to extend its cash runway.

About SER-155

SER-155 is an investigational, oral, live biotherapeutic designed to decolonize gastrointestinal (GI) pathogens, improve epithelial barrier integrity, and induce immune homeostasis, to prevent bacterial bloodstream infections, including those that can harbor antimicrobial resistance (AMR), as well as other pathogen associated negative clinical outcomes, in patients undergoing allogeneic hematopoietic stem cell transplantation (allo-HSCT).

SER-155 has been evaluated in a Phase 1b placebo-controlled study in patients undergoing allo-HSCT, which demonstrated a significant reduction in both bacterial bloodstream infections (BSIs) (77% relative risk reduction) and systemic antibiotic exposure, as well as lower incidence of febrile neutropenia. SER-155 has received Breakthrough Therapy designation for the reduction of bloodstream infections in adults undergoing allo-HCST and Fast Track designation for reducing the risk of infection and graft-versus-host disease in patients undergoing allo-HCST. The early development of the program was supported by Combating Antibiotic-Resistant Bacteria Biopharmaceutical Accelerator (CARB-X), a global non-profit partnership accelerating antibacterial products to address drug-resistant bacteria.

"Our third quarter demonstrated exceptional execution across our clinical portfolio," said Marianne De Backer, Chief Executive Officer, Vir Biotechnology. "We completed ECLIPSE 1 enrollment approximately two months ahead of schedule and continue to see strong momentum across ECLIPSE 2 and 3, positioning us well for our hepatitis delta regulatory submissions. We are excited to provide guidance for a comprehensive VIR-5500 data update in the first quarter of 2026, and we recently expanded into first-line prostate cancer with our ARPI combination study. These achievements reflect our team’s commitment to delivering transformative therapies to patients with significant unmet medical needs."

Pipeline Programs

Chronic Hepatitis Delta (CHD)

The ECLIPSE 1 Phase 3 trial has completed enrollment approximately two months ahead of the Company’s internal projections. Primary completion is expected in the fourth quarter of 2026, with topline data expected in the first quarter of 2027. ECLIPSE 1 evaluates the combination of tobevibart and elebsiran compared to deferred treatment in regions such as the U.S. where bulevirtide is not available or in other regions where its use is limited.
The ECLIPSE 2 Phase 3 trial continues enrolling well, and topline data are expected in the first quarter of 2027. ECLIPSE 2 evaluates the switch to the combination of tobevibart and elebsiran in participants who have not achieved undetectable hepatitis delta virus RNA with bulevirtide treatment.
The ECLIPSE 3 Phase 2b trial is progressing ahead of schedule with strong enrollment momentum, and topline data are expected in the first quarter of 2027. ECLIPSE 3 evaluates the combination of tobevibart and elebsiran compared to bulevirtide monotherapy in bulevirtide treatment-naïve participants.
Following positive data presented at American Association for the Study of Liver Diseases (AASLD) The Liver Meeting 2024, the Company will present Week 48 endpoint results from its SOLSTICE Phase 2 clinical study, in patients with CHD at AASLD The Liver Meeting 2025. The oral presentation will take place on Sunday, November 9.
Solid Tumors

VIR-5500, a PRO-XTEN dual-masked T-cell engager (TCE) targeting prostate-specific membrane antigen (PSMA), continues to advance through Phase 1 dose escalation as a monotherapy in heavily pre-treated patients with metastatic castration-resistant prostate cancer (mCRPC) and has demonstrated promising early anti-tumor activity and a favorable safety profile.
First patient dosed in Phase 1 clinical study of VIR-5500 in combination with ARPIs in first-line mCRPC.
The Company plans to share a comprehensive VIR-5500 data update in late-line patients in the first quarter of 2026.
VIR-5818, a PRO-XTEN dual-masked TCE targeting HER2, continues in a Phase 1 dose escalation study in combination with pembrolizumab.
VIR-5818 is the only dual-masked HER2-targeting TCE in clinical development and is being evaluated in multiple tumor types, including metastatic colorectal cancer (CRC).
VIR-5525, a PRO-XTEN dual-masked TCE targeting EGFR, continues enrollment in the Phase 1 trial as expected.
VIR-5525 leverages learnings from VIR-5500 and VIR-5818 and is being evaluated in a variety of EGFR-expressing solid tumors in areas of high unmet need, such as non-small cell lung cancer, CRC, head and neck squamous cell carcinoma, and cutaneous squamous cell carcinoma.
Preclinical Pipeline Candidates

Harnessing the Company’s deep immune system expertise combined with its discovery and engineering platform and proprietary dAIsY (data AI structure and antibody) AI engine, the Company continues to advance multiple undisclosed PRO-XTEN masked TCEs directed toward validated targets with potential application across a number of solid tumors.
Third Quarter 2025 Financial Results

Cash, Cash Equivalents and Investments: As of September 30, 2025, the Company had $810.7 million in cash, cash equivalents and investments, representing a decrease of approximately $81.4 million during the third quarter of 2025.

Revenues: Total revenues for the third quarter of 2025 were $0.2 million compared to $2.4 million for the same period in 2024.

Cost of Revenue: The change in cost of revenue for the third quarter of 2025 compared to the same period in 2024 was nominal.

Research and Development Expenses (R&D): R&D expenses for the third quarter of 2025 were $151.5 million, which included $5.5 million of non-cash stock-based compensation expense, and $75.0 million of milestone payments paid from restricted cash, compared to $195.2 million for the same period in 2024, which included $8.9 million of non-cash stock-based compensation expense and $102.8 million of license expenses. The decrease was primarily driven by lower license expenses and cost savings from previously announced restructuring initiatives, partially offset by higher clinical expenses from our ECLIPSE registrational program for CHD and progression of our oncology programs.

The $75.0 million milestone payment to former shareholders of Amunix Pharmaceuticals, Inc. was triggered by VIR-5525 achieving first-in-human dosing and was paid from restricted cash held in escrow since the execution of the license agreement with Sanofi S.A. (Sanofi), therefore having no impact on our reported cash position or runway. The prior year license expenses were primarily due to the recognition of the $102.8 million Sanofi upfront payment as in-process research and development expense in the third quarter of 2024.

Selling, General and Administrative Expenses (SG&A): SG&A expenses for the third quarter of 2025 were $22.2 million, which included $5.8 million of non-cash stock-based compensation expense, compared to $25.7 million for the same period in 2024, which included $7.8 million of non-cash stock-based compensation expense. The decrease was largely due to efficiencies and cost savings from previously announced restructuring initiatives.

Restructuring, Long-Lived Assets Impairment and Related Charges, Net: The Company incurred no restructuring, long-lived assets impairment and related charges, net for the third quarter of 2025 compared to $12.7 million for the same period in 2024. The decrease was due to the fact that our restructuring initiatives implemented in prior years were substantially completed by the end of 2024.

Other Income: Other income for the third quarter of 2025 was $10.5 million compared to $17.8 million for the same period in 2024. The decrease was primarily driven by lower interest income.

Provision for Income Taxes: The provision for income taxes for the third quarter of 2025 was nominal.

Net Loss: Net loss for the third quarter of 2025 was $163.1 million, or $1.17 per share, basic and diluted, compared to a net loss of $213.7 million, or $1.56 per share, basic and diluted for the same period in 2024.

2025 Financial Guidance

Based on current operating plans, the Company expects its cash, cash equivalents and investments to fund operations into mid-2027.

Conference Call
