## Exhibit 99.1

**Exhibit 99.1**

**Avalyn Reports First Quarter 2026 Financial Results and Recent Business Highlights**

On track to complete enrollment of MIST Phase 2b trial of AP01 in progressive pulmonary fibrosis (PPF) in mid-2026, with newly presented long term open-label extension clinical data that support favorable tolerability profile

Enrollment underway in AURA Phase 2 trial of AP02 in patients with idiopathic pulmonary fibrosis (IPF) with topline data anticipated by the end of 2027

Upsized initial public offering (IPO) gross proceeds of $345.0 million, together with approximately $123.1 million in cash, cash equivalents, and marketable securities as of March 31, 2026, projected to be sufficient to fund operations into 2029

**BOSTON, June 3, 2026** -- Avalyn Pharma Inc. (Nasdaq: AVLN), a clinical-stage biopharmaceutical company pioneering inhaled therapies to transform the treatment paradigm of serious, rare respiratory diseases, today announced financial results for the first quarter ended March 31, 2026 and recent business highlights.

"Our recent IPO marks a transformative moment for Avalyn, providing the capital to advance three potentially paradigm-shifting programs in pulmonary fibrosis, a disease where current oral antifibrotics are limited by tolerability challenges that prevent many patients from receiving the full benefit of treatment," said Lyn Baranowski, CEO of Avalyn Pharma. "By delivering inhaled therapies directly to the lungs through nebulization, our programs are designed to address the urgent gap in treatments for these deadly diseases. The combination of anti-fibrotic activity seen in our clinical trials to date, together with the open-label extension data to be presented at EULAR in patients with PPF, reinforce our conviction that improved tolerability can unlock the potential for extended duration of treatment and clinical benefit. With clinical readouts across each of our three programs expected in 2027, we are executing with focus and discipline as we work to redefine the standard of care for patients living with this devastating disease."

**Recent Pipeline Progress**

**AP01 (inhaled pirfenidone)**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•*MIST Phase 2b Trial On-Track to Complete Enrollment Mid-2026, with Multiple Recent Presentations Supporting its Clinical Profile.* 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•MIST is an ongoing Phase 2b randomized, double blind, placebo-controlled trial evaluating two doses of AP01 in patients with PPF. This 375-patient, 52-week trial is designed to assess safety and efficacy of AP01 with a primary endpoint of change in lung function measured by FVC. Enrollment is on-track to be completed mid-2026 with topline data anticipated in the second half of 2027.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•On June 6, 2026, the Company will present <u>data</u> from the PPF compassionate use cohort of its ATLAS open-label extension study at the European Alliance for Associations for Rheumatology (EULAR) Conference. Patients in this compassionate use cohort had late stage disease with no other treatment options. Study results indicate that after four years, AP01 remains generally well

------

tolerated in these patients with PPF, with an adverse event profile consistent with that observed in the ATLAS Phase 1b trial. Though this study was not designed for efficacy, a favorable trend in lung function trajectory as measured by FVC was seen out to 48 months compared with published data. These AP01 data, combined with previously reported long-term extension data in patients with IPF, suggest the potential for AP01 to impact disease progression and survival in patients with pulmonary fibrosis.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•In May 2026, Avalyn presented two <u>posters</u> at the American Thoracic Society (ATS) Annual Meeting in Orlando, FL, demonstrating its commitment to patients, and both hearing and addressing their concerns. Posters summarized how patient, care partner, and physician input informed improvements in instruction materials for the eFlow<sup>®</sup> Nebulizer System for AP01, and described the importance of healthcare communication from the patient perspective.

**AP02 (inhaled nintedanib)**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•*Enrollment Underway in AURA Phase 2 Trial.* In March 2026, Avalyn announced first patient dosing in its AURA trial of AP02**.** AURA is a Phase 2 randomized, double-blind trial evaluating two doses of AP02 administered twice daily in patients with IPF. The 12-week study is designed to enroll 160 patients to assess safety and efficacy, as measured by FVC, with topline data anticipated in late 2027.

**AP03 (inhaled combination of nintedanib and pirfenidone)**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•*Development Underway as Next-Generation Fixed-Dose Combination Therapy:* A Phase 1 trial of AP03, a therapeutic approach combining nebulized pirfenidone and nintedanib, is on track to initiate by the end of 2026.

**Recent Corporate Highlights**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•In May 2026, the Company completed an upsized IPO, with the sale of 19,166,667 shares of its common stock, which included the full exercise by the underwriters of their option to purchase an additional 2,500,000 shares of common stock, at $18.00 per share. The Company raised gross proceeds of approximately $345.0 million, before deducting underwriting discounts and commissions and other offering expenses.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Avalyn further strengthened its team to support the next phase of growth with the appointments of Adam Golden as General Counsel and Head of Business Development, and Frank Salisbury as Senior Vice President, Commercial.

**Upcoming Conference**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•**Jefferies Global Healthcare Conference, New York City.** Management will present a company overview on Thursday, June 4, 2026, at 9:55-10:25 a.m. ET. Access to the webcast can be found <u>here</u>.

**Financial Results for First Quarter 2026**

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•**Cash Position:** Cash, cash equivalents, and marketable securities were $123.1 million

as of March 31, 2026. This amount excludes the net proceeds of approximately $316.1 million raised with the company's IPO in May 2026. The company's current cash, cash equivalents, and marketable securities, including the net proceeds from its IPO, are projected to be sufficient to fund its current operating plans into 2029.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•**Research & Development (R&D) Expenses:** R&D expenses were $22.9 million for the first quarter of 2026, as compared to $15.3 million for the first quarter of 2025. The increase in R&D expenses was primarily driven by the progression of the AP01 Phase 2b trial and on-going open label extension study, as well the AP02 Phase 2 trial.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•**General & Administrative (G&A) Expenses:** G&A expenses were $5.0 million for the first quarter of 2026, as compared to $3.4 million for the first quarter of 2025. The increase in G&A expenses was primarily driven by personnel-related expenses, including stock-based compensation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•**Net loss:** Net loss was $26.9 million for the first quarter of 2026, as compared to $17.5 million for the first quarter of 2025.

**About Avalyn Pharma**<br> Avalyn aims to transform the treatment paradigm for pulmonary fibrosis and other serious, rare respiratory diseases. The company is advancing optimized inhaled formulations of established antifibrotic medicines designed to deliver drug directly to the lungs, enhance local efficacy, and reduce systemic side effects. Avalyn's AP01 program is an optimized inhaled formulation of pirfenidone currently being evaluated in MIST, a global Phase 2b clinical trial in patients with progressive pulmonary fibrosis (PPF). AP01 has indicated encouraging safety and clinical activity across Phase 1b and multi-year open-label extension trials, with long-term data supporting the potential to preserve lung function while improving tolerability relative to historical oral pirfenidone. Avalyn's AP02 program is an optimized inhaled formulation of nintedanib currently being evaluated in AURA, a global Phase 2 clinical trial in patients with idiopathic pulmonary fibrosis (IPF). Avalyn is also advancing AP03, an inhaled fixed-dose combination of pirfenidone and nintedanib, designed to deliver multiple antifibrotic mechanisms through a single lung-targeted platform. By leveraging its proprietary drug-device approach and deep expertise in rare respiratory disease development, Avalyn aims to establish a new standard of care in pulmonary fibrosis through inhaled, lung-targeted therapies.
