**Exhibit 99.1**

**Lyra Therapeutics Reports Third Quarter 2025 Financial Results and Provides Corporate Update**

– *Company plans new, confirmatory Phase 3 clinical trial of LYR-210 for treatment of chronic rhinosinusitis (CRS) without nasal polyps, on path to NDA submission* –

WATERTOWN, Mass., November 12, 2025 (GLOBE NEWSWIRE) -- Lyra Therapeutics, Inc. (Nasdaq: LYRA) ("Lyra" or the "Company"), a clinical-stage biotechnology company developing long-acting, anti-inflammatory sinonasal implants for the treatment of chronic rhinosinusitis (CRS), today reported its financial results for the third quarter ended September 30, 2025 and provided a corporate update.

"We are now focused on putting all the components in place for a new, confirmatory Phase 3 clinical trial to make progress toward a New Drug Application ("NDA") for LYR-210 as a six-month treatment for CRS patients without nasal polyps," said Maria Palasis, Ph.D., President and CEO, Lyra Therapeutics. "We are excited to move forward with our business strategy and to advance LYR-210 as a novel therapeutic option for millions of CRS patients who fail current medical therapy."

**Recent Business Highlights**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Lyra has established a clinical development plan to conduct an additional trial, based on meeting with FDA, to support the submission of an NDA for LYR-210 for the treatment of chronic rhinosinusitis (CRS) without nasal polyps.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Lyra presented the positive ENLIGHTEN 2 Phase 3 results as a Late-Breaking Scientific Oral Presentation at the Annual Meeting of the American Academy of Otolaryngology–Head and Neck Surgery (AAO-HNS) in October 2025.

**Third Quarter 2025 Financial Highlights**

Cash and cash equivalents as of September 30, 2025 were $22.1 million, compared with cash and cash equivalents of $40.6 million at December 31, 2024. Based on our current business plan, we anticipate that our cash and cash equivalents balance is sufficient to fund our operating expenses and capital expenditures into the third quarter of 2026.

Research and development expenses decreased by $1.9 million from $5.9 million to $4.0 million for the three months ended September 30, 2025 compared to the three months ended September 30, 2024.

The decrease in research and development expenses for the three months ended September 30, 2025 was primarily attributable to a decrease in clinical related costs of $2.1 million as we completed the ENLIGHTEN 2 trial for LYR-210 and a decrease of $0.1 million in employee related costs primarily driven by the effect of a

------

reduction in force that commenced in May 2024, partially offset by an increase in professional and consulting fees of $0.2 million and an increase of $0.1 million in product development and manufacturing costs.

General and administrative expenses decreased by $1.7 million from $3.9 million to $2.2 million for the three months ended September 30, 2025 compared to the three months ended September 30, 2024.

The decrease in general and administrative expenses for the three months ended September 30, 2025 was primarily driven by a decrease in employee related costs of $1.6 million and a $0.3 million decrease in allocation, support and depreciation costs, as we scaled back costs subsequent to announcing in May 2024 that the ENLIGHTEN 1 trial did not meet its primary endpoint, partially offset by a $0.2 million increase in professional, consulting and public company fees.

We incurred a restructuring credit in the amount of $21 thousand primarily related to severance and retention costs for the three months ended September 30, 2025 compared to a restructuring charge of $2.8 million for the same period in 2024.

Net loss for the third quarter 2025 was $6.0 million, compared to $11.9 million for the same period in 2024.
