conference call at 4:30 p.m. ET today
SAN DIEGO--(BUSINESS WIRE) -- May 7, 2026 -- Arcturus
Therapeutics Holdings Inc. (the “Company”, “Arcturus”, Nasdaq: ARCT), a messenger RNA medicines company focused
on the development of liver and respiratory rare disease therapeutics, today announced its financial results for the quarter ended March
31, 2026, and provided corporate updates.
“Arcturus continues to advance its rare
disease therapeutics portfolio. We have initiated enrollment of our 12-week CF Phase 2 study in the first quarter of 2026, earlier than
originally anticipated. We remain committed to advancing our inhaled mRNA therapy for people with CF Class I mutations,” said Joseph
Payne, President & CEO of Arcturus. “Also, during the first quarter of 2026, we met with the FDA regarding the pediatric clinical
development strategy for our OTC deficiency program and we now have a clear path toward initiating a pivotal trial which we will align
further at the EOP2 meeting later this year. We welcomed two seasoned C-suite leaders, Alan H. Cohen, MD, Chief Medical Officer and Dennis
M. Mulroy, Chief Financial Officer to strengthen the executive team.”
“We are pleased to announce a strong balance
sheet and runway of over two and a half years, allowing our company to reach important clinical and regulatory milestones for its rare
disease pipeline,” said Dennis M. Mulroy, Chief Financial Officer of Arcturus.
Recent Corporate Highlights
| · | Arcturus’ ARCT-032, an inhaled mRNA therapeutic
candidate for CF initiated enrollment of a new cohort in March 2026. This open label Phase 2 clinical study is currently enrolling up
to 20 Class I CF participants in the U.S. and abroad. The study will monitor 10 mg dosing – over 12 weeks – for safety and
evidence of early clinical benefits, including assessment of lung functional improvements (as measured by ppFEV1 and LCI),
along with two validated quality-of-life outcome measures and evaluation of any changes in high-resolution computed tomography (HRCT)
imaging. |
| · | Arcturus’ ARCT-810 program, an mRNA therapeutic
candidate for OTC deficiency, is broadening its development strategy to address the unmet medical needs of newborns and young children
affected by the most severe forms of OTC deficiency. The Company is actively engaged in complementary regulatory interactions and strategic
planning to support studies across both adult and pediatric populations, including those for whom liver transplantation remains the only
current option for survival beyond early childhood. In March 2026, the FDA provided a clear path forward in a Type C meeting toward a
pivotal pediatric study that requires additional exploratory data to establish the optimal dose and therapeutic effect. The Company is
collecting additional exploratory data in its preparation for an EOP2 meeting in second half of this year. |
| · | Meiji, partner to Arcturus and CSL Seqirus in
Japan, is actively preparing KOSTAIVE®, a self-amplifying mRNA COVID-19 vaccine, for the 2026/2027 season using a 2-dose vial presentation. |
| · | Arcturus strengthened its executive team with
the appointments of Chief Medical Officer and Chief Financial Officer to support the advancement of the Company’s therapeutic pipeline
and financial strategy. |
| o | Alan H. Cohen, MD, Chief Medical Officer, brings extensive clinical, medical affairs, and drug
development leadership, with deep experience across rare diseases, pulmonology, cardiovascular medicine, infectious diseases, vaccines,
and pediatrics. He has held senior medical leadership roles at global pharmaceutical and biotechnology companies and has a strong track
record advancing clinical programs from early development through post-approval commercialization, supporting clinical and therapeutic
strategies. He has served on the faculty of many highly regarded Pulmonary Centers of Excellence, including those at the University of
Colorado/National Jewish Center for Immunology & Respiratory Diseases, where he also was a resident and fellow, Washington University
School of Medicine, Emory University as well as the Morehouse School of Medicine, Johns Hopkins and most recently at Stanford University
School of Medicine. |
| o | Dennis M. Mulroy, Chief Financial Officer, brings more than 40 years of extensive financial and
operational leadership, with deep expertise in SEC reporting, capital markets, and commercialization where he supported numerous public
company transformations, value-creating transactions, and commercial product launches. Most recently he served as the CFO at AnaptysBio,
which recently completed a strategic transaction that resulted in two public companies, and greatly enhanced shareholder value. |
Financial Results for the three months ended
March 31, 2026
Cash Position and Balance Sheet:
Cash, cash equivalents
and restricted cash were $213.4 million as of March 31, 2026, and $232.8 million as of December 31, 2025. Through continued disciplined
execution and focus on our existing rare disease clinical programs, we continue to have a cash runway extending beyond the second quarter
of 2028.
Revenue in conjunction with strategic alliances
and collaborations:
Arcturus’ current primary revenue stream
relates to our grant agreement with BARDA. The year over year $27.3 million decrease in revenue was driven by lower revenue recognized
under the CSL collaboration as we pivot from infectious disease vaccine development toward rare disease clinical programs.
Operating expenses:
Total operating expenses for the three months
ended March 31, 2026, were $31.0 million compared to $46.2 million for the three months ended March 31, 2025.
Research and development expenses:
Research and development expenses were $21.5 million
for the three months ended March 31, 2026, compared to $34.9 million in the comparable period last year. The decrease was primarily driven
by lower manufacturing costs related to LUNAR-COVID and BARDA, as well as reduced clinical trial costs associated with the LUNAR-COVID
program. Additional decreases were attributable to lower payroll and benefits costs associated with lower stock-based compensation expense
and a reduction in headcount. These reductions were partially offset by higher manufacturing costs related to LUNAR-OTC.
General and Administrative Expenses:
General and administrative expenses were $9.5
million for the three months ended March 31, 2026, compared to $11.3 million in the comparable period last year. The decrease was primarily
due to reduced share-based compensation expense as well as reduced payroll and benefits costs associated with reductions in headcount.
Net Loss:
For the three months ended March 31, 2026, Arcturus
reported a net loss of approximately $27.0 million, or ($0.95) per diluted share, compared to a net loss of $14.1 million, or ($0.52)
per diluted share in the three months ended March 31, 2025.
