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

*FDA Accepted the Company's Response to the CRL for CARDAMYST™ (etripamil) Nasal Spray; New PDUFA Target Date of December 13, 2025*

*Milestone Strengthens Balance Sheet to Fully Commercialize CARDAMYST if Approved*

*Public Offering Raised Total Gross Proceeds of up to $170 Million if all Warrants are Exercised*

*$75 Million Royalty Purchase Agreement Payment from RTW Extended Through End of 2025*

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

"With the FDA's recent acceptance of our response to the CRL, our team is energized as we work toward the potential approval of CARDAMYST in its first indication, PSVT," said Joe Oliveto, President and Chief Executive Officer of Milestone. "In parallel to our regulatory progress, we completed an equity financing in July with high-quality investors which strengthened our balance sheet and extended our operating runway. Our goal is to make CARDAMYST quickly available to PSVT patients, should the FDA grant approval this year."

**Second Quarter and Recent Program Updates**

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

· **FDA accepted the Company's response to the Complete Response Letter (CRL) for CARDAMYST™ (etripamil) Nasal Spray and set a new Prescription Drug User Fee Act (PDFUA) target date of December 13, 2025.** In June,
Milestone submitted to the FDA its response to a CRL for CARDAMYST, its lead investigational product for the management of paroxysmal
supraventricular tachycardia (PSVT). On July 11, 2025, the Company announced the FDA accepted the response to issues raised in the
CRL and assigned a new PDUFA target date of December 13, 2025. Milestone has maintained its launch infrastructure that was in place
prior to the CRL and has restarted targeted pre-launch activities given the new potential approval date of CARDAMYST.

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

· **Phase 3 protocol of etripamil in AFib-RVR finalized.** Milestone has finalized the Phase 3 study
protocol following FDA's review and obtained concurrence with the Agency to proceed. The Company has paused initiation of enrollment
in the study to prioritize resources for the preparation of the expected launch of etripamil in PSVT.

**Second Quarter and Recent Corporate Updates**

· **In July 2025, Milestone completed a public equity offering, raising total gross proceeds of up to $170 million, if all Series A and B warrants are exercised for cash, including immediate net proceeds of approximately $48.7 million.** Milestone intends to use the proceeds from the underwritten public offering (the "Offering"), together with
existing cash and cash equivalents, to fund the continued development and commercial launch of CARDAMYST in its lead indication of PSVT,
as well as for working capital and other general corporate purposes. The Offering consisted of the sale and issuance of (i) 31,500,000
of its common shares (the "Shares"), accompanying Series A common warrants (the "Series A Common Warrants")
to purchase an aggregate of 31,500,000 common shares and accompanying Series B common warrants (the "Series B Common Warrants")
to purchase an aggregate of 31,500,000 common shares , at a combined public offering price of $1.50 per share and accompanying Series A
Common Warrant and Series B Common Warrant and (ii) in lieu of common shares to certain investors that so choose, pre-funded
warrants to purchase 3,502,335 common shares, accompanying Series A Common Warrants to purchase an aggregate of 3,502,335 common
shares and accompanying Series B Common Warrants to purchase an aggregate of 3,502,335 common shares, at a combined public offering
price of $1.499 per pre-funded warrant and accompanying Series A Common Warrant and Series B Common Warrant, which represented
the combined public offering price for the Shares and accompanying common warrants less the $0.001 per share exercise price for each such
pre-funded warrant. The net proceeds to the Company received from the Offering were approximately $48.7 million after deducting underwriting
commissions and estimated offering expenses payable by the Company.

· **Amended Royalty Agreement with RTW.** Milestone extended the marketing approval deadline in its $75
million purchase and sale agreement (the "Royalty Purchase Agreement") with existing shareholder, RTW Investments,
LP, and certain of its affiliates (RTW) from September 30, 2025 to December 31, 2025. The proceeds from the Royalty
Purchase Agreement are expected to fund the continued development and commercial launch of CARDAMYST in its lead indication of PSVT, following
potential FDA approval and satisfaction of other customary closing conditions.

**Second Quarter 2025 Financial Results**

· As of June 30, 2025, Milestone had cash, cash equivalents, and short-term investments of $43.4 million,
compared to $69.7 million as of December 31, 2024. Subsequent to the end of the quarter, the company raised net proceeds of approximately
$48.7 million from the Offering, as described above.

· There was no revenue for the second quarter ended June 30, 2025 or for the second quarter of 2024.

· Research and development expense for the second quarter of 2025 was $3.7 million, compared with $2.8 million
for the prior year period. For the six months ended June 30, 2025, research and development expense was $8.6 million compared
with $6.5 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 second quarter of 2025 was $3.8 million, compared with $5.0
million for the prior year period. For the six months ended June 30, 2025, general and administrative expense was $8.9
million, compared with the $9.0 million for the prior year period. The decrease between the quarters is primarily due to a
decrease in legal fees, professional fees, and personnel costs.

· Commercial expense for the second quarter of 2025 was $5.1 million, compared with $1.8 million for the
prior year period. For the six months ended June 30, 2025, commercial expense was $15.5 million compared with $4.7
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. As a result of the CRL, Milestone temporarily paused the ramping of operational
expenditures related to launch, but has maintained the capability to launch quickly, pending approval of CARDAMYST by the FDA.

· For the second quarter of 2025, net loss was $13.0 million, compared to $9.4 million for the prior year
period. For the six months ended June 30, 2025, Milestone's net loss was $33.7 million, compared to $19.7 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.

These and other risks are set forth in Milestone's filings with the U.S. Securities and Exchange Commission (SEC), including in its annual report on Form 10-K for the year ended December 31, 2025 and its quarterly report on Form 10-Q for the quarter ended June 30, 2025, in each case under the caption "Risk Factors," as such discussions may be updated from time to time by subsequent filings Milestone may make with the SEC.
