Oragenics Q2 2025 Shareholder Update

Advancing Brain-First Recovery Platform Toward Clinical Milestones
Pioneering Intranasal Therapeutics for Concussion

SARASOTA, Fla., Aug. 11, 2025 (GLOBE NEWSWIRE) -- Oragenics, Inc. (NYSE American: OGEN), a pioneering biotechnology company striving to develop brain-targeted therapeutics through proprietary intranasal delivery technology, today shared key strategic and financial milestones achieved during the second quarter of 2025 and shortly thereafter. These successes underscore the company's momentum as it strives to transform neurotrauma care and advance its lead candidate, ONP-002, toward becoming the first FDA-approved pharmacological treatment for concussion.

"We're not just developing another drug, we're striving to pioneer a new era of brain-first recovery that could transform how we treat neurological trauma," said Janet Huffman, Chief Executive Officer of Oragenics. "We believe that our proprietary nasal delivery platform and our lead candidate ONP-002 for concussion, the Company’s current cash position, combined with strategic partnerships, position us to lead a paradigm shift in neurotrauma care. We believe that early treatment could prevent chronic brain disorders as a result of mTBI."

CLINICAL LEADERSHIP AND COMPETITIVE ADVANTAGE
Strategic Evolution and Focus
Oragenics’ acquisition of ONP-002 in 2024 represents a strategic transformation, focusing the company's extensive R&D capabilities on high-impact neurological therapeutics with clear commercial pathways. We anticipate this focused approach may position Oragenics to achieve a successful drug development milestone.
We anticipate Phase IIa trials will launch in Q3 2025, which we believe will allow Oragenics to maintain a significant clinical advantage in the intranasal neurotrauma space, potentially advancing toward becoming the first company to bring an FDA-approved pharmacological treatment for concussion to market.
Key Clinical Milestones Achieved in Q2:

Human Research Ethics Committee (HREC) approval secured in Australia
Southern Star Research appointed as Clinical Research Organization (CRO)
US based cGMP manufacturing agreement finalized with Sterling Pharma Solutions

TRANSFORMATIONAL PLATFORM OPPORTUNITY
We believe Oragenics' proprietary intranasal delivery system positions the company at the forefront of the rapidly expanding nasal drug delivery market, projected to exceed $40 billion by 2030. We anticipate this technology may enable targeted, non-invasive delivery of therapeutics directly to the brain. Although the Company is focused on the treatment of concussion with its lead candidate ONP-002, the applications for its novel intranasal device may extend beyond concussion treatment to acute neurological emergencies and chronic neurodegenerative diseases.
Our Anticipated Technology Advantages:

Rapid onset and targeted brain biodistribution
Bypasses systemic circulation, reducing side effects
Non-invasive, patient and caretaker-friendly administration
Scalable manufacturing and delivery system
Potentially broad therapeutic applications across CNS conditions

BUILDING THE CONCUSSION CARE ECOSYSTEM
Industry Engagement and Strategic Partnerships
Oragenics' increased industry presence reflects our commitment to building comprehensive partnerships across the concussion care continuum. Our strategic engagements position us to participate in an integrated treatment ecosystem that aspires to address the full spectrum of brain injury care.
Q2 Industry Leadership:

2025 BIO International Convention (Boston, MA) -- Delivered corporate presentation on transforming concussion treatment paradigms
42nd Annual National Neurotrauma Society Symposium (Philadelphia, PA) -- Strengthened relationships with leading researchers and clinicians
3rd Nasal Formulation & Delivery Summit (Boston, MA) -- CMO shared insights on ONP-002's potentially revolutionary mechanism
NATO Blast Meeting (Canadian Forces College - Toronto, Canada) – CMO attended NATO Blast meeting and strengthened relationships with leading international researchers and clinicians
The 15^th Annual Traumatic Brain Injury Conference (Boston, MA) – CMO and CCO attended and delivered corporate presentation on ONP-002, clinical blood biomarkers and the need for a trigger to treat model

STRATEGIC CAPITAL POSITION
Strengthened Financial Foundation
Our recent $16.5 million capital raise through Series H Convertible Preferred Stock and Warrants reflects growing investor confidence in our transformational approach to neurotrauma treatment. These funds strategically position us to accelerate our lead program while advancing our nasal delivery platform.
Strategic Capital Deployment -- We anticipate our recent capital raise may allow us to:

Accelerate ONP-002 clinical development and Phase IIa and Phase IIb clinical trial execution
Advance platform technology for future therapeutic applications
Strengthen manufacturing and regulatory capabilities
Support operational excellence and working capital needs

"We continue to explore non-dilutive funding opportunities, including government grants and strategic partnerships, to maximize shareholder value while maintaining our focus on therapeutic development," added Huffman.
ANTICIPATED UPCOMING CATALYSTS AND MILESTONES

Phase IIa clinical trial initiation (Q3 2025)
IND submission to FDA for Phase IIb clinical trial (Q3-Q4 2025)

Anticipated Future Value Drivers (2026):

Phase IIa data readout (Q3 2026)
Phase IIb trial initiation in US (Q4 2026)

OPERATIONAL EXCELLENCE AND MARKET READINESS
Manufacturing and Regulatory Progress
Oragenics has secured critical infrastructure to support successful clinical execution and future commercial readiness:

Clinical Operations: Southern Star Research provides globally recognized CRO expertise with proven track record in Australia and Asia-Pacific region
Regulatory Strategy: HREC approval achieved; IND submission preparations underway for U.S. Phase IIb trials

FINANCIAL STRENGTH AND OPERATIONAL EFFICIENCY
Key Financial Highlights for Six Months Ended June 30, 2025:
Operational Discipline: Year-over-year improvements demonstrate our commitment to efficient capital deployment:

50% reduction in research and development expenses
8% decrease in general and administrative costs
6% decline in net losses for the six-month period

Post-Capital Raise Strength:

Gross proceeds: $16.5 million from Series H Preferred Stock and Warrants
Net proceeds: ~$15.2 million after fees and expenses

As we advance toward Phase IIa initiation, we anticipate strategic increases in R&D investment to support clinical excellence and accelerated development timelines.

MARKET OPPORTUNITY AND COMPETITIVE LANDSCAPE
Massive Unmet Medical Need
With no current FDA-approved treatments for concussion or mild traumatic brain injury (mTBI), the market for effective therapies represents a substantial and completely unmet opportunity. Our proprietary intranasal delivery platform we believe has the potential to offer significant advantages that have the potential to transform concussion management and recovery.
Market Dynamics:

No FDA-approved pharmacological treatments for concussion currently exist
Millions of cases annually across sports, military, and civilian sectors
Growing recognition of long-term effects and need for acute intervention
$8.9 billion global concussion market opportunity by 2027
$40+ billion nasal delivery technology market opportunity by 2030

Strategic Positioning: We believe that our first-mover advantage in intranasal neurotrauma therapeutics, combined with our platform technology's potential for broader applications, may position Oragenics as the category leader in brain-first recovery solutions.
