The earnings call summary and Q&A reveal mixed signals. While there are positive developments in product pipelines and regulatory progress, management's lack of specific guidance on revenue and clinical endpoints creates uncertainty. The Q&A highlighted potential for growth but also pointed to uncertainties in clinical trial outcomes and commercial revenues. No major catalysts like new partnerships or strong financial metrics were announced, leading to a neutral sentiment overall.
Revenue for Q3 2025 $17.2 million, a decrease of $24.5 million year-over-year. The decline was primarily driven by reduced revenues from the CSL collaboration, reflecting lower supply agreement activity and lower amortization of the upfront payment as KOSTAIVE became a commercial product.
Revenue for 9 months ended September 30, 2025 $74.8 million, a decrease of $54.7 million year-over-year. The decline was primarily driven by reduced revenues from the CSL collaboration, reflecting lower supply agreement activity and lower amortization of the upfront payment as KOSTAIVE became a commercial product.
Total Operating Expenses for Q3 2025 $33.7 million, a decrease from $52.4 million year-over-year. The decrease was primarily due to lower manufacturing costs for the COVID, flu, and CF programs, reduced clinical trial expenses for COVID and cystic fibrosis, and lower payroll and employee benefits.
Total Operating Expenses for 9 months ended September 30, 2025 $119.8 million, a decrease from $191.8 million year-over-year. The decrease was primarily due to lower manufacturing and clinical costs related to the COVID program, lower manufacturing costs for the cystic fibrosis and flu program, and reduced payroll and benefits.
R&D Expenses for Q3 2025 $23.3 million, a decrease from $39.1 million year-over-year. The decrease was primarily driven by lower manufacturing costs for the COVID, flu, and CF programs, reduced clinical trial expenses for COVID and cystic fibrosis, and lower payroll and employee benefits.
R&D Expenses for 9 months ended September 30, 2025 $87.7 million, a decrease from $151.4 million year-over-year. The decrease was primarily driven by lower manufacturing and clinical costs related to the COVID program, lower manufacturing costs for the cystic fibrosis and flu program, and reduced payroll and benefits.
G&A Expenses for Q3 2025 $10.4 million, a decrease from $13.3 million year-over-year. The decrease was primarily due to reduced share-based compensation expense as well as reduced payroll and benefits.
G&A Expenses for 9 months ended September 30, 2025 $32.1 million, a decrease from $40.4 million year-over-year. The decrease was primarily due to reduced share-based compensation expense as well as reduced payroll and benefits.

Cash, Cash Equivalents, and Restricted Cash as of September 30, 2025 $237.3 million, compared to $293.9 million as of December 31, 2024. The decrease reflects ongoing operational expenses and cost reductions.
ARCT-032 Program: This is a messenger RNA therapeutic candidate for cystic fibrosis (CF). Interim data from Phase II clinical trial showed that treatment with inhaled 10-milligram doses daily over 28 days in 6 Class I CF adults was generally safe and well tolerated. Reductions in mucus burden were observed in four of the six participants. The company plans to evaluate daily dosing over a 12-week duration in up to 20 CF participants starting in the first half of 2026.
ARCT-810 Program: This is a messenger RNA therapeutic candidate for ornithine transcarbamylase deficiency (OTC deficiency). Positive interim Phase II data has been reported. Regulatory meetings are planned for the first half of 2026 to discuss pivotal trial strategy for both pediatric and adult populations.
KOSTAIVE COVID-19 Vaccine: The Japanese partner, Meiji Seika Pharma, launched the 2-dose vial of KOSTAIVE updated for the JN.1 variant XEC in Japan. Phase III data showed robust immune response and safety. However, the BLA filing in the U.S. has been delayed indefinitely due to regulatory changes and uncertain commercial visibility.
ARCT-2304 Pandemic Influenza Vaccine: This next-gen STARR vaccine candidate for pandemic A/H5N1 influenza virus showed promising Phase I results. It induced a strong immune response after a single dose and further increased responses with a second dose. No safety or tolerability concerns were raised.
Global Expansion for CF Treatment: The company highlighted the higher prevalence of Class I CF in regions outside the U.S., including Europe, India, the Middle East, and Israel, indicating potential market expansion opportunities.
KOSTAIVE Commercialization in Asia and Europe: CSL is expected to continue supporting the commercialization of KOSTAIVE in Asia and Europe despite challenges in the U.S. market.
Cost Reductions: The company has implemented cost reductions, including lower manufacturing and clinical trial expenses for COVID, flu, and CF programs, as well as reduced payroll and employee benefits. These measures have extended the cash runway into 2028.
Financial Performance: Revenues for Q3 2025 were $17.2 million, a decrease from the previous year due to reduced revenues from the CSL collaboration. Operating expenses also decreased significantly, driven by lower R&D and G&A costs.
Focus on CF and OTC Programs: The company is prioritizing its cystic fibrosis and OTC programs, delaying other initiatives like the KOSTAIVE BLA filing in the U.S. to allocate resources effectively.
Regulatory Changes Impacting KOSTAIVE: The FDA's sudden regulatory changes have indefinitely delayed the KOSTAIVE BLA filing, creating uncertainty around its commercial visibility in the U.S. This has led to reduced expenses and a focus shift to other programs.
Revenue Decline: Revenues for the third quarter and nine months ended September 30, 2025, decreased significantly compared to the same periods in 2024, primarily due to reduced revenues from the CSL collaboration and lower supply agreement activity.
Operating Expense Reductions: Operating expenses have decreased year-over-year, driven by lower manufacturing and clinical trial costs for COVID, flu, and CF programs, as well as reduced payroll and employee benefits. However, these reductions may impact the pace of program development.
Dependence on CSL Collaboration: The company relies on CSL to commercialize KOSTAIVE in Asia and Europe, which could pose risks if CSL's efforts do not meet expectations or market conditions change.
Cash Runway Extension: The delay in the Phase III cystic fibrosis clinical trial and planned cost reductions have extended the cash runway into 2028. However, this delay could slow the progress of critical programs.
ARCT-032 Program for Cystic Fibrosis: The company plans to initiate a 12-week study in up to 20 CF participants in the first half of 2026 to evaluate the safety and preliminary efficacy of ARCT-032. This follows the completion of the third cohort's top-line data analysis.
ARCT-810 Program for OTC Deficiency: Regulatory meetings are planned for the first half of 2026 to discuss pivotal trial strategies for both pediatric and adult populations. The company aims to align with the FDA on the path to approval.
KOSTAIVE COVID-19 Vaccine: The company has indefinitely delayed the BLA filing for KOSTAIVE in the U.S. due to regulatory changes and uncertain commercial visibility. However, commercialization efforts will continue in Asia and Europe through CSL.
ARCT-2304 Pandemic Influenza Vaccine: The company plans to further develop ARCT-2304, a next-generation STARR vaccine candidate for pandemic A/H5N1 influenza virus, based on positive Phase I study results showing robust immune responses and no safety concerns.
Financial Guidance: Cost reductions in Q4 2025 and the delay in the Phase III cystic fibrosis trial have extended the cash runway into 2028. General and administrative expenses are expected to decrease slightly in fiscal year 2026.

The earnings call presents a mixed picture: strong pipeline developments with FDA fast track designation and cash runway extension are positives, but declining revenue and a net loss are negatives. The Q&A reveals cautious optimism about CF and OTC programs, yet management's lack of clarity on competitor impact and data release timing raises uncertainties. These factors, combined with no new partnerships or shareholder return changes, suggest a neutral stock movement prediction.
The earnings call reveals a decline in revenue and increased net loss, alongside an extended cash runway due to cost reductions and facility consolidation. The Q&A session highlights uncertainties, with management avoiding clear answers on key milestones and guidance. Despite a decrease in expenses, the lack of anticipated revenue milestones until 2028 and unclear regulatory feedback contribute to a negative sentiment. While some operational efficiencies were achieved, the overall financial outlook and management's vague responses suggest a negative stock price movement in the short term.
The earnings call reveals several negative financial indicators: a significant revenue drop, increased operating expenses, and a larger net loss. Despite some positive developments like the KOSTAIVE launch and strategic partnerships, the financial health and guidance issues weigh heavily. The Q&A section shows management's reluctance to provide clear guidance, adding uncertainty. These factors, along with a lack of strong positive catalysts, suggest a negative sentiment. Without market cap data, we assume a moderate negative reaction in stock price, likely between -2% and -8%.
