Warren, N.J., March 4, 2026 - Aquestive Therapeutics, Inc. (NASDAQ: AQST) ("Aquestive" or the "Company"), a pharmaceutical company advancing medicines to bring meaningful improvement to patients' lives through innovative science and delivery technologies, today reported financial results for the fourth quarter and full year ended December 31, 2025, and provided a progress update on the Company's key 2026 objectives.

"We are well-positioned in 2026 to advance Anaphylm, the first and only oral epinephrine rescue medication, towards approval for patients around the world," said Daniel Barber, President and Chief Executive Officer of Aquestive. "We continue to believe the value proposition will be transformative and ultimately save lives. We are focused on rapidly addressing the human factors focused deficiencies cited by the FDA in their recent Complete Response Letter. Our commercial infrastructure is intact and transferable to our new timeline, the allergy market continues to grow, and patient preference remains strongly in favor of the innovation Anaphylm represents. As recently announced, we have strengthened our leadership with the addition of Dr. Greenhawt, an internationally recognized expert in allergy and immunology, as the Chief Medical Officer of the Company. Additionally, we remain well-positioned financially to launch Anaphylm in the U.S., if approved by the FDA. We've never been more confident in Anaphylm's potential to make a meaningful difference for the allergy community."

Anaphylm™ (dibutepinephrine) Sublingual Film

Anaphylm is a non-device based epinephrine product candidate being developed for the treatment of Type I allergic reactions, including anaphylaxis. The Company believes Anaphylm has the potential to be the first and only non-invasive, orally delivered epinephrine product, if approved by the U.S. Food and Drug Administration (FDA).

On January 30, 2026, Aquestive received a Complete Response Letter (CRL) from the FDA for the New Drug Application (NDA) for Anaphylm in patients weighing 30 kilograms or more. The CRL identified deficiencies related to human factors validation, including potential challenges associated with pouch opening and film placement, as well as a request for a single pharmacokinetics (PK) study to assess the impact of packaging and labeling modifications. The FDA also provided labeling comments intended to inform the final label, if approved by the FDA.

The CRL did not identify any chemistry, manufacturing, or controls (CMC) deficiencies, and clinical results submitted as part of the NDA regarding comparability to auto-injectors (such as EpiPen® and Auvi-Q®), such as bracketing, repeat dose, and sustainability, were not questioned. No additional studies beyond the requested human factors validation study and related PK study were identified. The FDA indicated that the human factors and PK studies may be conducted in parallel.

To address the items outlined in the CRL, a new human factors validation study and a PK study are planned. A Type A meeting with the FDA has been requested to discuss the most efficient path forward for resubmission, with the NDA anticipated to be resubmitted in the third quarter of 2026, subject to completion of the required studies and

expected FDA response timelines. The Company plans to request an accelerated review upon resubmission, but no expedited review can be guaranteed.

The Company continues to advance its global expansion strategy for Anaphylm, including ongoing regulatory engagement in Canada and preparatory activities in the European Union. These efforts are intended to support potential future submissions and expand access to the Company's non-invasive epinephrine therapy globally.

Aquestive will continue to prepare for the launch of Anaphylm, a potentially transformative product for the emergency treatment of severe allergic reactions, including anaphylaxis. The initial focus of the Company's launch preparation is to optimize Anaphylm's market access for patients, if approved by the FDA. Aquestive is also increasing awareness of Anaphylm through the continued execution of its medical affairs strategy, including presenting scientific data at medical forums throughout 2026. The Company remains committed to a successful launch of Anaphylm, if approved by the FDA.

AQST-108 (epinephrine) Topical Gel

AQST-108 is a topical epinephrine prodrug gel product candidate being evaluated for alopecia areata (AA) and other potential dermatologic or localized indications. In December 2025, the Company successfully opened an Investigational New Drug (IND) application for AQST-108 with the FDA and received supportive written feedback for continued development of this product candidate.

An initial first-in-human clinical trial of AQST-108 evaluated topical application and systemic exposure and did not identify any serious or topical adverse events. Building on these results, the Company successfully completed dosing in a second Phase 1 clinical trial in the first quarter of 2026 and the data readout from the study is expected in the second quarter of 2026. The intent of this study is to further characterize the safety, tolerability, and pharmacologic profile of the program and to inform potential future development opportunities, including indication selection.

An estimated 6.7 million people in the United States have been affected by AA. Of those affected, 43% are considered severe. The existing therapies for AA are janus kinase (or JAK) inhibitors. These systemic treatments with known side effects come with a "black box" warning and are expensive for patients. Even with these limitations, the current estimated market opportunity for JAK inhibitors is over One Billion U.S. dollars. Since AQST-108 is topical and there is evidence that it acts at the application site, it may not have systemic side effects. As a result of these conditions, AQST-108, if approved by the FDA as a treatment for AA, has the potential to capture meaningful market share for the treatment of these patients.

The topical formulation of AQST-108 is designed to act locally at the site of application, which may support evaluation in settings where minimizing systemic exposure is desirable. This localized delivery approach provides an opportunity to explore additional value for this product beyond a single indication, while maintaining a disciplined, data-driven development strategy.

Commercial Collaborations

Aquestive continues to manufacture products for the licensing and supply collaborations that it has established. The Company manufactured approximately 47 million doses in the fourth quarter 2025, compared to approximately 43 million doses in the fourth quarter 2024. The Company continues to manufacture Indivior's Suboxone® Sublingual Film product and the Company's other global collaborations, including Sympazan® (clobazam) Oral Film product for Assertio Holdings, Inc. in the U.S., Ondif® (Ondansetron) Oral Film product for Hypera Pharma in Brazil and Emylif® (riluzole) Oral Film product by Zambon S.p.A in Europe. Aquestive's manufacturing business remains steady, with the gradual decline of Suboxone being offset by growth across newer collaborations.

The Company, being a U.S. based manufacturer with intellectual property domiciled in the U.S., confirms that its supply chain currently remains largely unaffected by both implemented and proposed government tariffs, providing continued reliability and stability in production and global distribution for the near term.

Sales of royalty-based products, inclusive of Sympazan® (clobazam) Oral Film for the treatment of seizures associated with Lennox-Gastaut Syndrome in patients two years of age and older, and Azstarys®

(serdexmethylphenidate and dexmethylphenidate) for the treatment of Attention Deficit Hyperactivity Disorder (ADHD) in patients six years of age and older, continued to contribute to the Company's revenue in the fourth quarter of 2025.

Libervant® (diazepam) Buccal Film remains tentatively approved until January 2027, the scheduled date of expiration of U.S. market orphan drug exclusivity of an FDA approved product of another company. Aquestive continues to believe that expanding patient access to non-invasive seizure rescue therapies is vital and remains committed to putting Libervant in the hands of patients when granted full approval for U.S. market access by the FDA.

RTW Amendment, Warrant and Share Purchase Agreement

On March 3, 2026, the Company entered into Amendment No. 1 to the Purchase and Sale Agreement, dated August 13, 2025, with funds managed by RTW Investments, LP ("RTW"). The Amendment extends the marketing approval deadline for Anaphylm from its original date to June 30, 2027. Concurrently, the Company entered into a Warrant Issuance Agreement with funds managed by RTW, pursuant to which the Company agreed to issue a warrant to such funds to purchase up to 375,000 shares of the Company's common stock, par value $0.001 per share (the "Common Stock"), at an exercise price of $4.00 per share, expiring on March 3, 2029. On March 3, 2026, the Company also entered into a Share Purchase Commitment Agreement with certain RTW-affiliated funds, pursuant to which such funds committed to purchase, in the aggregate, not less than $5,000,000 of Common Stock during the 90-day period following the effective date of the agreement, at the then current market price as of the date of such purchase(s), as determined in accordance with Rule 415(a)(4) under the Securities Act of 1933, as amended.

Legal Settlement

In December 2025, Aquestive entered into a confidential legal settlement with Neurelis, Inc. related to a civil tort case filed by Neurelis, Inc. in December 2019. Net of insurance payments and reduced ongoing legal costs, Aquestive expects the cash impact in 2026 of such settlement to be the same as or lower than forecasted prior to the settlement.

Fourth Quarter 2025 Financials

Total revenues increased to $13.0 million in the fourth quarter 2025, from $11.9 million in the fourth quarter 2024. This 10% increase in revenue was primarily driven by increases in manufacture and supply revenue.

Manufacture and supply revenue increased to $12.0 million in the fourth quarter 2025 from $10.7 million in the fourth quarter 2024, primarily due to increases in Suboxone revenues and Ondif revenues.

Research and development (R&D) expenses decreased to $3.2 million in the fourth quarter 2025 from $4.9 million in the fourth quarter 2024. The decrease in R&D expenses was primarily due to a decrease in clinical trial costs associated with the continued advancement of the Anaphylm development program and decreases in R&D personnel costs and share-based compensation.

Excluding one-time legal expenses, selling, general and administrative expenses increased to $19.6 million in the fourth quarter 2025 from $16.0 million in the fourth quarter 2024. Including the one-time legal expenses, selling, general and administrative expenses increased to $32.8 million in the fourth quarter 2025 from $16.0 million in the fourth quarter 2024, primarily due to higher legal expenses of approximately $13.6 million, higher commercial spending of approximately $3.7 million in preparation for the planned launch of Anaphylm, higher personnel expenses of approximately $0.8 million, and higher share-based compensation of approximately $0.2 million, partially offset by lower severance expenses of approximately $1.7 million, and lower regulatory and licensing fees of approximately $0.5 million.

Excluding one-time legal expenses, Aquestive's net loss for the fourth quarter 2025 was $18.7 million, or $0.15 for both basic and diluted loss per share, compared to the net loss for the fourth quarter 2024 of $17.1 million, or $0.19 for both basic and diluted loss per share. Including one-time legal expenses, Aquestive's net loss for the fourth quarter 2025 was $31.9 million, or $0.26 for both basic and diluted loss per share, compared to the net loss for the fourth quarter 2024 of $17.1 million, or $0.19 for both basic and diluted loss per share. The increase in net loss was primarily driven by increases in selling, general and administrative expenses, and manufacture and supply expenses,

partially offset by decreases in research and development expenses and increases in revenues and interest income and other income, net.

Excluding one-time legal expenses, Non-GAAP adjusted EBITDA loss was $14.1 million in the fourth quarter 2025, compared to Non-GAAP adjusted EBITDA loss of $11.0 million in the fourth quarter 2024. Non-GAAP adjusted EBITDA loss excluding adjusted R&D expenses and one-time legal expenses was $10.8 million in the fourth quarter 2025, compared to a Non-GAAP adjusted EBITDA loss excluding adjusted R&D expenses of $6.6 million in the fourth quarter 2024.

Full Year 2025 Financials

Excluding the impact of one-time recognition of deferred revenues during the full year 2024, total revenues decreased by $1.5 million, or 3% to $44.5 million for the full year 2025. As a reminder, the one-time recognition of deferred revenue in the prior year was due to the termination of licensing and supply agreements. Including the deferred revenue recognized in the prior year, total revenues decreased to $44.5 million for the full year 2025 from $57.6 million for the full year 2024.

Manufacture and supply revenue increased to $40.2 million for the full year 2025 from $40.0 million for the full year 2024, primarily due to increases in Ondif revenues, partially offset by decreases in Suboxone revenues.

R&D expenses decreased to $17.2 million for the full year 2025 from $20.3 million in the full year 2024. The decrease in R&D expenses was primarily due to lower clinical trial costs associated with the continued advancement of the Anaphylm development program, partially offset by increases in product research expenses as well as R&D personnel costs and share-based compensation.

Excluding one-time legal expenses, selling, general and administrative expenses increased to $66.6 million for the full year 2025 from $50.2 million for the full year 2024. Including one-time legal expenses, selling, general and administrative expenses increased to $79.8 million for the full year 2025 from $50.2 million for the full year 2024. The increase primarily represents higher legal expenses of approximately $14.3 million, higher commercial spending of approximately $9.6 million in preparation for the planned launch of Anaphylm, Anaphylm PDUFA fee of $4.3 million, higher personnel expenses of approximately $1.9 million, higher regulatory expenses related to Anaphylm of approximately $1.0 million, and higher share-based compensation expenses of approximately $0.9 million, partially offset by lower severance expenses of approximately $2.8 million, and lower insurance expenses of approximately $0.6 million.

Excluding one-time legal expenses, Aquestive's net loss for the full year 2025 was $70.6 million, or $0.66 for both basic and diluted loss per share, compared to the net loss for the full year 2024 of $44.1 million, or $0.51 for both basic and diluted loss per share. Including one-time legal expenses, Aquestive's net loss for the full year 2025 was $83.8 million, or $0.78 for both basic and diluted loss per share, compared to the net loss for the full year 2024 of $44.1 million, or $0.51 for both basic and diluted loss per share. The increase in net loss was primarily driven by increases in selling, general and administrative expenses, and manufacture and supply expenses, and decreases in revenues, partially offset by decreases in R&D expenses and increases in interest income and other income, net.

Excluding one-time legal expenses, Aquestive's Non-GAAP adjusted EBITDA loss was $49.7 million for the full year 2025, compared to Non-GAAP adjusted EBITDA loss of $23.0 million for the full year 2024. Non-GAAP adjusted EBITDA loss excluding adjusted R&D expenses and one-time legal expenses was $34.4 million for the full year 2025, compared to Non-GAAP adjusted EBITDA loss excluding adjusted R&D expenses of $4.0 million for the full year 2024.

As of December 31, 2025, cash and cash equivalents were $121.2 million.

2026 Outlook

Aquestive is providing its full year 2026 financial outlook. The Company expects:

			Guidance
Total revenue (in millions)			$46 to $50
Non-GAAP adjusted EBITDA loss (in millions)			$35 to $30

Our Non-GAAP adjusted EBITDA loss guidance for 2026 includes costs associated with the resubmission of the NDA for Anaphylm, continued pre-commercial infrastructure spending for Anaphylm, clinical trial for AQST-108, and regulatory applications for Anaphylm in Canada and the EU. Current guidance does not include costs associated with the sales and marketing of Anaphylm, if approved by the FDA.

About Anaphylm™

Anaphylm™ (epinephrine) sublingual film is a polymer matrix-based epinephrine prodrug product. Anaphylm is similar in size to a postage stamp, weighs less than an ounce, and begins to dissolve on contact. No water or swallowing is required for administration. The primary packaging for Anaphylm is thinner and smaller than an average credit card, can be carried in a pocket, and is designed to withstand weather excursions such as exposure to rain and/or sunlight. The Anaphylm trade name for AQST-109 has been conditionally approved by the FDA. Final approval of the Anaphylm proprietary name is conditioned on FDA approval of the product candidate.

About AQST-108

AQST-108 (epinephrine) topical gel is a topically delivered adrenergic agonist prodrug product candidate. Aquestive completed a first in human study for AQST-108 without any serious or topical adverse events. AQST-108 is based on Aquestive's Adrenaverse™ platform which contains a library of over twenty epinephrine prodrug product candidates intended to control absorption and conversion rates across a variety of possible dosage forms and delivery sites.

About Libervant®

Libervant® (diazepam) buccal film is a buccally, or inside of the cheek, administered film formulation of diazepam, a benzodiazepine intended for the acute treatment of intermittent, stereotypic episodes of frequent seizure activity (i.e., seizure clusters, acute repetitive seizures) that are distinct from a patient's usual seizure pattern in patients with epilepsy. Aquestive developed Libervant as an alternative to the device-based products currently available for patients with refractory epilepsy, including a rectal gel and nasal spray products. The FDA approval for U.S. market access received in April 2024 for Libervant was for these epilepsy patients between two and five years of age. However, the FDA converted this approval to a "tentative approval" due to a recent court ruling finding that the FDA did not have authority to approve Libervant for U.S. market access for patients aged between two and five years due to the existing orphan drug market exclusivity granted by the FDA to an intranasal spray of another company. The FDA granted tentative approval in August 2022 for Libervant for treatment of these epilepsy patients twelve years of age and older. U.S. market access for Libervant patients is currently subject to the expiration of the existing orphan drug market exclusivity of the previously FDA approved drug scheduled to occur in January 2027.

Important Safety Information

Do not give Libervant to your child between the ages of two and five if your child is allergic to diazepam or any of the ingredients in Libervant or has an eye problem called acute narrow angle glaucoma.

What is the most important information I should know about Libervant?

•Libervant is a benzodiazepine medicine. Taking benzodiazepines with opioid medicines, alcohol, or other central nervous system (CNS) depressants (including street drugs) can cause severe drowsiness, breathing problems (respiratory depression), coma, and death. Get emergency help right away if any of the following happens:

▪shallow or slowed breathing,

▪breathing stops (which may lead to the heart stopping),

▪excessive sleepiness (sedation).

Do not allow your child to drive a motor vehicle, operate heavy machinery, or ride a bicycle until you know how taking Libervant with opioids affects your child.

•Risk of abuse, misuse, and addiction. Libervant is used in children 2 to 5 years of age. The unapproved use of Libervant has a risk for abuse, misuse, and addiction, which can lead to overdose and serious side effects including coma and death.

•Serious side effects including coma and death have happened in people who have abused or misused benzodiazepines, including diazepam (the active ingredient in Libervant). These serious side effects may also include delirium, paranoia, suicidal thoughts or actions, seizures, and difficulty breathing. Call your child's healthcare provider or go to the nearest hospital emergency room right away if you get any of these serious side effects.

◦Your child can develop an addiction even if your child takes Libervant as prescribed by your child's healthcare provider.

◦Give Libervant exactly as your child's healthcare provider prescribed.

◦Do not share Libervant with other people.

◦Keep Libervant in a safe place and away from children.

•Physical dependence and withdrawal reactions. Libervant is intended for use if needed in order to treat higher than usual seizure activity. Benzodiazepines, including Libervant, can cause physical dependence and withdrawal reactions, especially if used daily. Libervant is not intended for daily use.

◦Do not suddenly stop giving Libervant to your child without talking to your child's healthcare provider. Stopping Libervant suddenly can cause serious and life-threatening side effects, including, unusual movements, responses, or expressions, seizures that will not stop (status epilepticus), sudden and severe mental or nervous system changes, depression, seeing or hearing things that others do not see or hear, homicidal thoughts, an extreme increase in activity or talking, losing touch with reality, and suicidal thoughts or actions. Call your child's healthcare provider or go to the nearest hospital emergency room right away if your child gets any of these symptoms.

◦Some people who suddenly stop benzodiazepines have symptoms that can last for several weeks to more than 12 months including, anxiety, trouble remembering, learning, or concentrating, depression, problems sleeping, feeling like insects are crawling under your skin, weakness, shaking, muscle twitching, burning, or prickling feeling in your hands, arms, legs or feet, and ringing in your ears.

◦Physical dependence is not the same as drug addiction. Your child's healthcare provider can tell you more about the differences between physical dependence and drug addiction.

•Do not give your child more Libervant than prescribed or give Libervant more often than prescribed.

Libervant can make your child sleepy or dizzy and can slow your child's thinking and motor skills.

•Do not allow your child to drive a motor vehicle, operate machinery, or ride a bicycle until you know how Libervant affects your child.

•Do not give other drugs that may make your child sleepy or dizzy while taking Libervant without first talking to your child's healthcare provider. When taken with drugs that cause sleepiness or dizziness, Libervant may make your child's sleepiness or dizziness much worse.

Like other antiepileptic medicines, Libervant may cause suicidal thoughts or actions in a small number of people, about 1 in 500.

•Call a healthcare provider right away if your child has any of these symptoms, especially if they are new, worse, or worry you:

◦thoughts about suicide or dying

◦new or worse depression

◦feeling agitated or restless

◦trouble sleeping (insomnia)

◦acting aggressive, being angry or violent

◦other unusual changes in behavior or mood

◦attempts to commit suicide

◦new or worse anxiety or irritability

◦an extreme increase in activity and talking (mania)

◦new or worse panic attacks

◦acting on dangerous impulses

•Pay attention to any changes, especially sudden changes in mood, behaviors, thoughts, or feelings.

•Keep all follow-up visits with your child's healthcare provider as scheduled.

•Call your child's healthcare provider between visits as needed, especially if you are worried about symptoms. Suicidal thoughts or actions can be caused by things other than medicines. If your child has suicidal thoughts or actions, your child's healthcare provider may check for other causes.

What are the possible side effects of Libervant?

•The most common side effects of Libervant are sleepiness and headache.

•These are not all the possible side effects of Libervant.

•Call your doctor for medical advice about side effects. You may report side effects to FDA at 1 800 FDA-1088.
