**Milestone Pharmaceuticals Reports Third Quarter 2025 Financial Results and Provides Regulatory and Corporate Update**

*PDUFA Target Date of December 13, 2025 for CARDAMYST™ (etripamil) Nasal Spray in Paroxysmal Supraventricular Tachycardia (PSVT)* 

*Promotional Launch Plans Set with Quick-Start Capability Upon Potential FDA Approval* 

*$82.6 million in Cash at September 30; Successful Equity Offering and Amended Royalty Purchase Agreement Provide Resources for Successful Launch* 

MONTREAL and CHARLOTTE, N.C., November 12, 2025 (GLOBE NEWSWIRE) -- Milestone Pharmaceuticals Inc. (Nasdaq: MIST) today reported financial results for the third quarter ending September 30, 2025, and provided corporate and regulatory updates.

"We are approaching our December 13 Prescription Drug User Fee Act (PDUFA) date with optimism and excitement for the opportunity to bring CARDAMYST (etripamil) nasal spray to patients suffering from symptomatic PSVT," said Joseph Oliveto, President and Chief Executive Officer of Milestone Pharmaceuticals. "Our team has recently increased our pre-launch activities to better enable market readiness. We strengthened our balance sheet with a successful equity financing last quarter, and together with the $75 million royalty payment upon FDA approval, we believe we have resources in place to drive a successful commercial launch."

**Third Quarter and Program Updates**

*<u>Etripamil for</u> <u>patients with PSVT</u>*

· **A New Drug Application (NDA) for CARDAMYST is currently being reviewed by the U.S. Food and Drug Administration (FDA), with a** **PDFUA action date of December 13, 2025.** Milestone has strengthened our commercialization capabilities
and plans to launch CARDAMYST quickly following FDA approval.

·  **<u>New analysis</u> of etripamil clinical data presented at the American Heart Association (AHA) Scientific Sessions 2025 on November 10.** Results from more than 600 unique enrolled patients showed aligned efficacy and safety of
 etripamil across multiple study phases, types of trial design, and geographic regions, with
 etripamil treatment achieving consistently greater conversion rates for symptomatic PSVT
 episodes compared with placebo arms.

· **Recent presentations and peer-reviewed publications** highlight the growing body of data supporting
 etripamil nasal spray as a potential rapid, self-administered treatment for PSVT and AFib-RVR.
 Importantly, etripamil was referenced in recent <u>AHA ACLS Guidelines</u> noting the potential
 of intranasal calcium channel blockers for future treatment algorithms. Separately, NODE-303
 long-term safety data were published in the *<u>Journal of Cardiovascular Electrophysiology</u>* .

*<u>Etripamil for patients with atrial fibrillation with rapid ventricular rate (AFib-RVR)</u>*

· **Phase 3 protocol of etripamil in AFib-RVR (ReVeRA-301) finalized.** Milestone is poised to enter
 a pivotal Phase 3 program in AFib-RVR, on the strength of the successful ReVeRA
 Phase 2 trial. The Company intends to follow the supplemental NDA regulatory approval
 pathway, discussed with the FDA, and expects to leverage data from the PSVT NDA along with
 the results from the planned single AFib-RVR Phase 3 study for what would potentially be
 a second indication for etripamil. The <u>ReVeRA-301 study</u> design
 for etripamil in AFib-RVR was presented at HRX 2025.

**Third Quarter and Recent Corporate Updates**

· **Milestone well-financed for potential CARDAMYST launch from recent public equity offering and amended Royalty Purchase Agreement (RPA).** The Company <u>completed</u> an underwritten
 public offering providing immediate net proceeds of approximately $48.7 million and amended
 RPA in July 2025. The proceeds from the offering and RPA are expected to fund the continued
 development and commercial launch of CARDAMYST in its lead indication of PSVT, following
 potential FDA approval around the PDUFA date of December 13<sup>th</sup>.

**Third Quarter 2025 Financial Results** 

· As of September 30, 2025, Milestone had cash, cash equivalents, and short-term investments of $82.6 million,
compared to $69.7 million as of December 31, 2024.

· No revenue was reported in the third quarter ended September 30, 2025 or for the third quarter of 2024.

· Research and development expense for the third quarter of 2025 was $3.9 million, compared with $4.0 million
for the prior year period. For the nine months ended September 30, 2025, research and development expense was $12.6 million compared
with $10.4 million for the same period in 2024. The increase was primarily due to higher consulting and outside service costs
that were partially offset by lower personnel-related costs.

· General and administrative expense for the third quarter of 2025 was $3.3 million, compared with $3.7
million for the prior year period. For the nine months ended September 30, 2025, general and administrative expense was $12.2
million, compared with the $12.7 million for the prior year period. The decrease between the quarters is primarily due to a
decrease in professional fees and personnel costs.

· Commercial expense for the third quarter of 2025 was $4.6 million, compared with $1.9 million for the
prior year period. For the nine months ending September 30, 2025, commercial expense was $20.1 million compared with $6.6
million for the prior year period. These increases are a result of additional personnel costs, professional costs and other operational
expenses related to preparation for the launch of CARDAMYST. With the resolution of the Complete Response Letter (CRL) we are now ramping
operational expenditures in order to launch quickly following the potential approval of CARDAMYST by the FDA.

· For the third quarter of 2025, net loss was $11.9 million, compared to $9.4 million for the prior year
period. For the nine months ended September 30, 2025, Milestone's net loss was $45.6 million, compared to $29.2 million in
the prior year period.

**About Etripamil**

Etripamil is Milestone's lead investigational product. It is a novel calcium channel blocker nasal spray under clinical development for frequent and often highly symptomatic episodes of PSVT and AFib-RVR. It is designed as a self-administered rapid response therapy for patients thereby bypassing the need for immediate medical oversight. If approved, etripamil is intended to provide health care providers with a new treatment option to enable on-demand care and patient self-management. This portable, self-administered treatment may provide patients with active management and a greater sense of control over their condition. CARDAMYST™, the conditionally approved brand name for etripamil nasal spray, is well studied with a robust clinical trial program that includes a completed Phase 3 clinical-stage program for the treatment of PSVT and Phase 2 trial for the treatment of patients with AFib-RVR.
