strategy and requirements to support registration. Refractory Chronic Cough • The Company initiated the Phase 2b LAKE trial in patients with RCC in the second quarter of 2026 . The protocol includes a sample size re-estimation ( SSRE) analysis once 50% of the participants complete treatment which is expected to occur in the fourth quarter of 2026 . The Company will report the outcome of the SSRE once available and expects to report topline results from the trial in the second half of 2027. Second Quarter 2026 Financial Highlights Cash, cash equivalents and marketable securities: The Company ended the second quarter of 2026 with $318.9 million. In April 2026 , the Company completed an underwritten common stock offering, resulting in net proceeds of approximately $16 2.3 million, after deducting underwriting discounts, commissions and offering expenses. The Company expects its current cash, cash equivalents and marketable securities to extend its cash runway into 2030 and fund the development of Haduvio for the treatment of patients with IPF-related chronic cough, through potential FDA approval. The Company also expects these cash resources will enable the Company to fund the clinical development program through Phase 3 for the treatment of patients with non-IPF ILD-related chronic cough, and the ongoing Phase 2b LAKE trial for the treatment of patients with RCC. The planned spending of these resources does not include any commercial expenses related to the commercial launch of Haduvio or a Phase 3 clinical trial in RCC. Research and development (R&D) expenses: R&D expenses for the second quarter of 2026 increased to $15.2 million from $9.4 million in the same period in 2025, primarily due to increased clinical development expenses for the Phase 3 OCEAN-1 trial, the Phase 2b LAKE trial, the Phase 3 OCEAN-2 trial and the Phase 1 NDA supportive studies, as well as increases in stock-based compensation and personnel related expenses. These increases were partially offset by decreased costs for the Phase 2b CORAL trial of Haduvio for patients with IPF-related chronic cough. General and administrative (G&A) expenses: G&A expenses for the second quarter of 2026 increased to $5.4 million from $4.3 million in the same period in 2025, primarily due to an increase in stock-based compensation and personnel related expenses, partially offset by decreased outside services and professional fees. Other Income, net: Other Income, net for the second quarter of 2026 increased to $2.7 million from $1.4 million in the same period in 2025, primarily due to an increase in interest income from higher invested cash equivalent and marketable securities balances. Net loss: For the second quarter of 2026 , the Company reported a net loss of $17.8 million, compared to a net loss of $12.3 million in the same period in 2025.

Wainwright 28th Annual Global Investment Conference • September 14-16 : Morgan Stanley 24th Annual Global Healthcare Conference About Trevi Therapeutics, Inc. Trevi Therapeutics, Inc. is a clinical-stage biopharmaceutical company developing the investigational therapy Haduvio™ ( oral nalbuphine extended-release) for the treatment of chronic cough in patients with idiopathic pulmonary fibrosis ( IPF), non-IPF interstitial lung disease ( non-IPF ILD), and refractory chronic cough ( RCC). In clinical trials, Haduvio showed a statistically-significant reduction in cough frequency, consistent across baseline cough frequencies, and showed improvements in patient-reported outcomes, in both patients with IPF-related chronic cough and in patients with RCC. Haduvio is believed to act on the cough reflex arc both centrally and peripherally as a kappa agonist and a mu antagonist ( KAMA), targeting opioid receptors that play a key role in controlling chronic cough. Nalbuphine is not currently scheduled by the U.S. Drug Enforcement Agency. Chronic cough in patients with IPF and non-IPF ILD is a condition with high unmet need and no FDA-approved therapies. There are ~140,000 U.S. patients with IPF, and two-thirds of these patients are faced with uncontrolled chronic cough. Additionally, there are ~228,000 U.S. patients with non-IPF ILD, with 50-6 0% having uncontrolled chronic cough. The impact of chronic cough is significant, with patients coughing up to 1,500 times per day. This consistent cough, and any associated damage, may lead to a higher risk of morbidity and mortality, including worsening disease, a higher risk of progression, increased respiratory hospitalizations, and a decline in patients' quality of life. RCC is a condition with high unmet need and no FDA-approved therapies. RCC is defined as a persistent cough lasting >8 weeks despite treatment for an underlying condition ( i.e., asthma, gastroesophageal reflux disease, non-asthmatic eosinophilic bronchitis, upper airway cough syndrome, or post-nasal drip) and includes unexplained chronic cough. There are ~2-3 million U.S. patients with RCC, and it is believed to be associated with cough reflex hypersensitivity involving both the central and peripheral nervous systems. RCC is highly debilitating and may impact patients physically, psychologically, and socially. Trevi intends to propose Haduvio as the trade name for oral nalbuphine ER. Its safety and efficacy have not been evaluated by any regulatory authority. For more information, visit www.TreviTherapeutics.com and follow Trevi on X ( formerly Twitter) and LinkedIn.
