Incannex Highlights Strong Balance Sheet with Approximately
$75 Million in Cash and No Debt as Company Advances IHL-42X Development
Company well-funded to complete DReAMzz Phase 2
study while preserving capital for optimized Phase 3 program
Melbourne and New York – 18 March 2026 –
Incannex Healthcare Inc. (Nasdaq: IXHL), a clinical-stage biopharmaceutical company developing combination therapies for high-impact
indications, today reported that it holds approximately $75 million in cash with no debt, following the completion of its recently
announced financing led by dedicated healthcare-focused institutional investors.
At current trading levels, Incannex’s market
capitalization is approximately $46 million — representing a significant disconnect to the Company’s $75 million
cash position and resulting in a negative enterprise value. Management believes this disconnect does not reflect the Company’s financial
strength or, the continued advancement of its clinical pipeline, or the external validation demonstrated by the participation of healthcare-focused
institutional investors in the recently completed financing.
The participation of healthcare-focused institutional
investors in this financing reflects meaningful external validation of both the Company’s clinical program and the long-term value
potential of IHL-42X. Incannex now holds approximately $75 million in cash with no debt, positioning the Company with a strong balance
sheet as it advances IHL-42X for obstructive sleep apnea (OSA) and PSX-001 for the treatment of generalized anxiety disorder (GAD).
Capital Position Supports Near- and Long-Term Development
Proceeds from the recently completed financing are
expected to fund the Company’s DReAMzz Phase 2 crossover dose-optimization study for IHL-42X. The study is designed to further
optimize the ratio of the two active pharmaceutical ingredients within the drug candidate, with the goal of maximizing efficacy across
both objective physiological endpoints and patient-reported outcomes.
Funding DReAMzz with proceeds from the recent financing
allows the Company to preserve the majority of its existing capital for the next stage of development, including an optimized Phase 3
program.
The Company’s board-approved share buyback program
remains available and carries remaining capacity, providing management with an additional tool to deliver shareholder value when market
conditions warrant.
Continued Progress Advancing IHL-42X
Over the past year, Incannex has made substantial
progress advancing the clinical development of IHL-42X, including:
| ● | Successful Phase 2 clinical results demonstrating statistically significant improvements in obstructive
sleep apnea outcomes |
| ● | Advancement into the DReAMzz Phase 2 crossover dose-optimization study, designed to further enhance
efficacy ahead of Phase 3 and supported by FDA Fast Track designation |
| ● | Establishment of a Clinical Advisory Board comprised of leading experts in the obstructive sleep apnea
field, providing guidance on clinical strategy and study design |
| ● | Appointment of a leading contract research organization and recruitment of clinical sites |
| ● | A clearly defined pathway toward an optimized Phase 3 development program |
While the positive Phase 2 results could have supported
direct progression into Phase 3, the Company elected to undertake the DReAMzz study to further refine dosing and maximize the probability
of success in late-stage development. Management believes this approach reduces execution risk, improves the probability of Phase 3 success,
and represents the most capital-efficient route to a registrational outcome — with the potential to shorten the overall pathway
to registration by optimizing the program ahead of Phase 3. Importantly, the Company expects to begin dosing patients in the DReAMzz study
within the coming months — a near-term milestone that reflects continued forward momentum in the program.
Progress Advancing PSX-001 for Generalized Anxiety Disorder
In addition to IHL-42X, Incannex continues to advance
PSX-001, the Company’s oral synthetic psilocybin therapy for the treatment of generalized anxiety disorder (GAD).
PSX-001 has generated positive clinical outcomes supporting
the therapeutic potential of the program. The Company has established a leading clinical advisory board comprised of experts in psychiatry
and psychedelic-assisted therapies, providing strategic guidance on clinical development and study design. With an open IND with the FDA
and a clear pathway to upcoming milestones, management believes PSX-001 represents a high-value second clinical asset within the Incannex
pipeline, targeting a large and substantially underserved patient population.
“Following the completion of this financing,
Incannex is in a strong financial position — approximately $75 million in cash, no debt, and well-funded through our DReAMzz
study and into an optimized Phase 3 program,” said Joel Latham, President and Chief Executive Officer of Incannex Healthcare.
“This disciplined capital strategy allows us to advance IHL-42X from a position of financial strength while maintaining a robust
balance sheet as we progress toward late-stage development and potential registration. The healthcare-focused institutional investors
who participated in this financing share our conviction in the long-term value proposition of the program, and their participation reflects
meaningful external validation of both the science and the strategy.”
Mr. Latham added, “At current levels, we are
trading at a meaningful disconnect to our cash balance alone — before attributing any value to two advancing clinical programs,
FDA Fast Track designation, or the contributions of our clinical advisory boards. We believe that disconnect is unsustainable, and that
continued execution will correct it.”
Positioned for Value Creation
With $75 million in cash, no debt, two advancing
clinical programs, and a clear development pathway for both IHL-42X and PSX-001, Incannex is moving forward from a position of financial
and operational strength. Management believes the Company’s current valuation presents a compelling opportunity, and remains focused
on executing its development strategy to drive recognition of the underlying value of its programs.
