New Investment in Milestone Pharmaceuticals

RTW Completes $25 Million Private Placement in Milestone Pharmaceuticals

RTW Venture Fund Limited (the "Company"), the London listed investment company focused on identifying transformative assets with high growth potential across the life sciences sector, is pleased to note the announcement by Milestone Pharmaceuticals, Inc. (Nasdaq: MIST) ("Milestone") on 23 July 2020 of its $25 million private placement agreement with affiliates of existing shareholder, RTW Investments, LP (the "Investment Manager"). The Company confirms that it participated in the private placement together with other funds managed by the Investment Manager.

Milestone is a publicly-traded clinical stage biopharmaceutical company focused on the development and commercialization of innovative cardiovascular medicines. Milestone is advancing Etripamil, its lead investigational product, through Phase 3 clinical trials for paroxysmal supraventricular tachycardia ("PSVT"). Etripamil is a novel calcium channel blocker designed as a self-administered nasal spray for a rapid response therapy in episodic cardiovascular conditions, which may shift the current treatment paradigm for many patients with PSVT from the emergency department to the at-home setting.

Prior to the private placement, the Investment Manager led an $80 million Series D cross-over financing round in Milestone in October 2018 and has continued to support Milestone as it IPOed in May 2019, remaining the largest shareholder and owning 17.5% of the shares outstanding.

Roderick Wong, MD, Managing Partner of RTW Investments, the Investment Manager said,"Bringing therapies to patients is often a nonlinear journey, and we are excited to continue to support Milestone's work to bring the first outpatient therapeutic for PSVT patients, who have limited treatment options outside of the hospital. We are confident the updated registrational trial that the Milestone team designed in coordination with the FDA maximizes Etripamil's chances to show both statistically and clinically impactful results. Now more than ever we are committed to see Milestone successfully advance this program through the pivotal trial."

The Company's investment in Milestone marks the addition of a fourteenth portfolio company. The Investment Manager is looking forward to growing the Company's investment pipeline and updating shareholders on further opportunities in due course.

Milestone Pharmaceuticals Announces $25 Million Private Placement

Montreal and Charlotte, NC, July 23, 2020 - Milestone Pharmaceuticals Inc. (Nasdaq: MIST), a biopharmaceutical company focused on the development and commercialization of innovative cardiovascular medicines, today announced that it has entered into a securities purchase agreement with affiliates of an existing shareholder, RTW Investments, LP, for a $25 million private placement. The private placement is expected to close on or about July 24, 2020, subject to the satisfaction of customary closing conditions.

The Company is selling pre-funded warrants to acquire an aggregate 6,655,131 common shares for aggregate gross proceeds of $25 million, or a purchase price of $3.7465 per pre-funded warrant. Each pre-funded warrant is exercisable for one of the Company's common shares at an exercise price of $0.01 per share, have no expiration date, and are immediately exercisable, subject to certain beneficial ownership limitations.

Milestone expects to use the proceeds from the sale of the pre-funded warrants for general corporate purposes, research and development, business development, working capital and general and administrative expenses. The Company believes that net proceeds from the private placement, together with its existing cash, cash equivalents and short-term investments, will be sufficient to fund its planned operations into the second quarter of 2022.

The securities to be sold in the private placement, including the shares issuable upon exercise thereof, have not been registered under the Securities Act of 1933, as amended (the "Securities Act"), or any state or other applicable jurisdiction's securities laws, and may not be offered or sold in the United States absent registration or an applicable exemption from the registration requirements of the Securities Act and applicable state or other jurisdictions' securities laws. The Company has agreed to file a registration statement with the U.S. Securities and Exchange Commission (the "SEC") registering the resale of the common shares issuable upon the exercise of the pre-funded warrants issued in the private placement no later than the 30th day after the closing of the private placement. In addition, the issuance of the pre-funded warrants under the private placement constitutes a related-party transaction under Multilateral Instrument 61-101 - Protection of Minority Security Holders in Special Transactions ("MI 61-101") due to the participation by an insider of the Company. The transaction is exempt from the formal valuation and minority shareholder approval requirements of MI 61-101 pursuant to sections 5.5(a) and 5.7(1)(a) of MI 61-101 as neither the fair market value of the securities issued to nor the consideration paid by such person exceeds 25% of the Company's market capitalization. The Company has not filed a material change report 21 days prior to the issuance of the pre-funded warrants set out above as no agreement was in place at that time.

This press release shall not constitute an offer to sell or the solicitation of an offer to buy these securities, nor shall there be any offer, solicitation or sale of these securities in any jurisdiction in which such offer, solicitation or sale would be unlawful. Any offering of the securities under the resale registration statement will only be made by means of a prospectus.
