(TSXV: NGEN) (OTCQB: NGENF), a clinical-stage biopharmaceutical company developing first-in-class neuroreparative therapeutics for spinal cord injury and other neurologic disorders, today announced its second quarter 2025 financial results, including a letter to shareholders from Adam Rogers, MD, the Company’s Chairman and Interim Chief Executive Officer, providing a detailed business update. Letter from Adam Rogers, MD, Chairman and Interim Chief Executive Officer: To my fellow shareholders, The medical community has long been taught that after spinal cord injury, neurons surrounding a lesion become dystrophic and die, leaving little hope for recovery. The late Dr. Jerry Silver devoted his career to challenging this narrative, and in doing so, laid the scientific foundation for NervGen. As Chairman and NervGen’s largest investor, I stepped into the role of Interim Chief Executive Officer because I am determined to ensure that the breakthrough science and pioneering vision of Dr. Silver, whose life’s work culminated in the creation of NVG-291, fulfills its potential to restore function and independence for people living with spinal cord injury (SCI). In carrying forward this vision, I am committed to raising the standard of communication at NervGen. We will provide shareholders and the SCI community with clear, accessible insights and transparent interpretations of our results, so that the impact of our CONNECT SCI Study, and the promise NVG-291 holds, is fully recognized and appreciated. The second quarter of 2025 marked a historic turning point for NervGen and the SCI community. After decades of virtually no therapeutic progress in spinal cord injury, we announced unprecedented topline results from our CONNECT SCI Study. We show for the first time that daily subcutaneous NVG-291 treatment, a pharmacologic candidate, significantly improved corticospinal connectivity and restored meaningful function for people with chronic SCI. These results represent both a scientific breakthrough and a pivotal step forward for the millions worldwide living with spinal cord injuries. For too long, the standard of care in SCI has been limited to acute stabilization and rehabilitation, offering little to no path to functional recovery. NervGen is redefining this outdated paradigm. Our mission is to advance NVG-291 and establish a new standard of care capable of restoring function, increasing independence, and transforming lives.

112-970 Burrard Street, Unit 1290, Vancouver, BC V6Z 2R4 Canada The coming months represent a significant inflection point as we move from proof-of-concept success into the next stage of development. Since sharing positive topline data from our CONNECT SCI Study, we have initiated a comprehensive analysis of NVG-291’s efficacy profile, which remains ongoing. To fully characterize these results, we are collaborating with key opinion leaders at leading spinal cord injury centers of excellence, along with clinical experts, bioinformatics specialists, and patient advocacy organizations. This forthcoming analysis will guide near-term regulatory discussions with the U.S. Food and Drug Administration (FDA), including seeking alignment on expedited pathways and designations that could potentially accelerate access to NVG-291 for people living with spinal cord injury. NervGen stands at a rare moment of opportunity. Our CONNECT SCI Study topline results are more than a milestone; they demonstrate that recovery after spinal cord injury is possible. We are advancing NVG-291 to establish a future in which pharmacologic therapy can restore function and increase independence for people living with spinal cord injury. With the continued trust of our shareholders, the engagement of the SCI community, and the dedication of the NervGen team, we enter a new chapter defined by purpose, progress, and renewed hope. Sincerely, Adam Rogers, MD Chairman and Interim CEO NervGen Pharma Corp. Pipeline Progress The Company has initiated a comprehensive analysis of NVG-291’s efficacy profile following its CONNECT SCI Study topline results. This forthcoming analysis will guide near-term regulatory discussions with the FDA, including seeking alignment on expedited pathways and designations to potentially accelerate access to NVG-291 for people living with spinal cord injury. In August 2025, the Company announced positive preclinical results from two U.S. Department of Defense sponsored studies, where NVG-291-R demonstrated significant functional recovery in models of traumatic hearing loss and peripheral nerve injury (PNI): Novel Preclinical Findings in Blast-Induced Sensorineural Hearing Loss • Significant Hearing Restoration: In a rat model exposed to shock waves, either a single high- pressure blast or a series of low-pressure blasts, daily subcutaneous NVG-291-R treatment led to statistically significant improvements in hearing thresholds across all frequencies by end-of-study at Day 30, preventing profound and permanent hearing loss observed in untreated animals. Novel Preclinical Findings in Peripheral Nerve Injury • Significant Neuromuscular Function and Axonal Regeneration: In moderate and severe models of PNI, daily subcutaneous NVG-291-R treatment led to statistically significant improvements in neuromuscular function and axonal regrowth. Increases in compound muscle action potentials and specific tetanic force were associated with a higher total number and density of axons distal to the injury site. Functional and regenerative gains were observed as early as 4 weeks post-injury.

112-970 Burrard Street, Unit 1290, Vancouver, BC V6Z 2R4 Canada Financial Results Cash and Investments: NervGen had cash and investments of $15.7 million as of June 30, 2025, compared to $17.3 million as of December 31, 2024. The decrease in funds available is due to operating activities related to the ongoing CONNECT SCI Study, which were partially offset by proceeds from the Company’s ATM program, warrant exercises, and option exercises in the current year. Research & Development (R&D) Expenses: R&D expenses were $2.7 million for the three months ended June 30, 2025, compared to $3.8 million in the same period in 2024. The decrease in the three months ended June 30, 2025, is related to lower clinical and regulatory costs primarily due to a grant milestone earned during the period which is recorded as an offset to clinical costs and decreased costs due to the completion of the chronic cohort of the CONNECT SCI Study during the quarter. Decreased clinical spend was offset by increased costs incurred for research, preclinical, and quality related initiatives. General and Administrative (G&A) Expenses: G&A expenses were $3.8 million for the three months ended June 30, 2025, compared to $2.2 million for the same period in 2024. The increase in the three months ended June 30, 2025, is primarily related to higher compensation related expenses, including non-cash stock-based compensation expense. Additionally, expenses were higher due to external legal counsel costs in relation to Canadian and U.S. corporate securities matters. Net Loss: For the three months ended June 30, 2025, net loss was $9.1 million, or $0.13 per basic and diluted common share. The net loss for the quarter included $4.8 million of non-cash expenses pertaining to amortization, stock-based compensation, unrealized foreign exchange and a $2.7 million non-cash loss due to the fair value adjustment of the warrant derivative. For the three months ended June 30, 2024, net loss was $7.8 million, or $0.11 per basic and diluted common share which included $3.5 million of net non-cash expenses pertaining to amortization, stock-based compensation, unrealized foreign exchange gain on cash and a $2.2 million non-cash loss due to the fair value adjustment of the warrant derivative. About NVG-291 NervGen holds exclusive worldwide rights to NVG-291, a first- and potential best-in-class therapeutic peptide targeting nervous system repair. NVG-291’s technology is licensed from Case Western Reserve University and is based on academic studies that demonstrated the preclinical efficacy of NVG-291-R, the rodent variant of NVG-291, in animal models of spinal cord injury. These studies implicated multiple potential molecular and cellular mechanisms by which NVG-291-R promotes neurorepair and functional improvement in both central and peripheral nervous system injury models. The implicated mechanisms include the promotion of neuronal sprouting, or plasticity, remyelination, and promotion of a non-inflammatory phenotype in the microglial cells. NervGen has received Fast Track designation from the FDA and Orphan Designation from the EMA for NVG-291 in individuals with spinal cord injury.
