PROSPECTUS
6,655,131 Common Shares
[MISSING IMAGE: lg_milestonepharma-4c.jpg]
This prospectus covers the offer and resale by the selling shareholders identified in this prospectus of up to an aggregate of 6,655,131 of our common shares, no par value per share, issuable upon exercise of pre-funded warrants sold to the selling shareholders in a private placement on July 24, 2020. We refer to these underlying common shares as the warrant shares.
We are not selling any common shares under this prospectus and will not receive any proceeds from the sale by the selling shareholders of the warrant shares. We will, however, receive the nominal exercise price per share of $0.01 for any pre-funded warrants exercised for cash.
Sales of the warrant shares by the selling shareholders may occur at fixed prices, at market prices prevailing at the time of sale, at prices related to prevailing market prices or at negotiated prices. The selling shareholders may sell warrant shares to or through underwriters, broker-dealers or agents, who may receive compensation in the form of discounts, concessions or commissions from the selling shareholders, the purchasers of the warrant shares, or both.
We are paying the cost of registering the warrant shares covered by this prospectus as well as various related expenses. The selling shareholders are responsible for all selling commissions, transfer taxes and other costs related to the offer and sale of their warrant shares.
Our common shares are listed for trading on The Nasdaq Global Select Market under the symbol “MIST.” On August 18, 2020, the last reported sale price of our common shares was $8.03 per share.
Investing in our common shares involves a high degree of risk. You should review carefully the risks and uncertainties described in the section titled “Risk Factors” on page 2 of this prospectus and any similar section contained in the applicable prospectus supplement and in any free writing prospectuses we have authorized for use in connection with a specific offering, and under similar headings in the documents that are incorporated by reference into this prospectus.

TABLE OF CONTENTS
 
SUMMARY
Overview
We are a biopharmaceutical company focused on the development and commercialization of innovative cardiovascular medicines. Our lead product candidate etripamil is a novel, potent and short-acting calcium channel blocker that we designed as a rapid-onset nasal spray to be self-administered by patients. We are developing etripamil to treat paroxysmal supraventricular tachycardia, or PSVT, atrial fibrillation, and other cardiovascular indications.
PSVT is a rapid heart rate condition characterized by episodes of supraventricular tachycardia, or SVT, that start and stop without warning. Episodes of SVT are often experienced by patients with symptoms including palpitations, sweating, chest pressure or pain, shortness of breath, sudden onset of fatigue, lightheadedness or dizziness, fainting and anxiety. Calcium channel blockers have long been approved for the treatment of PSVT as well as other cardiac conditions. Calcium channel blockers available in oral form are frequently used prophylactically to control the frequency and duration of future episodes of SVT. For treatment of episodes of SVT, approved calcium channel blockers are administered intravenously under medical supervision, usually in the emergency department. The combination of convenient nasal-spray delivery, rapid-onset and short duration of action of etripamil has the potential to shift the current treatment paradigm for episodes of SVT away from the burdensome and costly emergency department setting. If approved, we believe that etripamil will be the first self-administered therapy for the rapid termination of episodes of SVT wherever and whenever they occur.
Corporate Background
We were incorporated under the Canada Business Corporations Act in 2003 and continued under the Business Corporations Act (Québec) in 2017. Our principal executive offices are located at 1111 Dr. Frederik-Philips Blvd., Suite 420, Montréal, Québec, Canada H4M 2X6, and our telephone number is (514) 336-0444. In January 2017, we incorporated our wholly owned subsidiary, Milestone Pharmaceuticals USA, Inc., a Delaware corporation. Our corporate website address is www.milestonepharma.com. Information contained on, or accessible through, our website is not a part of this prospectus supplement. We have included our website in this prospectus supplement solely as an inactive textual reference.
Implications of Being an Emerging Growth Company and Smaller Reporting Company
We qualify as an “emerging growth company” as defined in the Jumpstart Our Business Startups Act of 2012, or the JOBS Act. An emerging growth company may take advantage of relief from some of the reporting requirements and other burdens that are otherwise applicable generally to public companies. These provisions include:

being permitted to provide only two years of audited financial statements, in addition to any required unaudited interim financial statements, with correspondingly reduced “Management’s Discussion and Analysis of Financial Condition and Results of Operations” disclosure;

not being required to comply with the auditor attestation requirements in the assessment of our internal control over financial reporting;

not being required to comply with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory audit firm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements;

reduced disclosure obligations regarding executive compensation in our periodic reports, proxy statements and registration statements; and

not being required to hold a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved.

USE OF PROCEEDS
We will not receive any of the proceeds from the sale or other disposition of the warrant shares by the selling shareholders pursuant to this prospectus. Upon any exercise of any of the pre-funded warrants for cash, the applicable selling shareholders would pay us the exercise price set forth in the pre-funded warrants, which is a nominal amount ($0.01 per common share). The pre-funded warrants are also exercisable on a cashless basis. If any of the pre-funded warrants are exercised on a cashless basis, we would not receive any cash payment from the applicable selling shareholders upon any such exercise of the pre-funded warrants.
We will bear the out-of-pocket costs, expenses and fees incurred in connection with the registration of the warrant shares to be sold by the selling shareholders pursuant to this prospectus. Other than registration expenses, the selling shareholders will bear underwriting discounts, commissions, placement agent fees or other similar expenses payable with respect to sales of the warrant shares.

TABLE OF CONTENTS
 
SELLING SHAREHOLDERS
On July 22, 2020, we entered into a securities purchase agreement with the selling shareholders named in this prospectus, pursuant to which we sold pre-funded warrants to purchase up to an aggregate of 6,655,131 of our common shares, no par value per share, at a purchase price of $3.7465 per pre-funded warrant, on July 24, 2020 in a private placement receiving aggregate gross proceeds of approximately $25 million. The pre-funded warrants have an exercise price of $0.01 per common share, are exercisable immediately and may be exercised at any time, from time to time, until exercised in full, subject to certain beneficial ownership limitations. A holder (together with its affiliates and other attribution parties) may not exercise any portion of a pre-funded warrant to the extent that immediately prior to or after giving effect to such exercise the holder would own more than 9.99% of our outstanding common shares immediately after exercise, which percentage may be changed at the holder’s election to a lower or higher percentage upon 61 days’ notice to us, subject to the terms of the pre-funded warrants.
Under the terms of the securities purchase agreement, we also agreed to file a registration statement within 30 days after the closing of the private placement to register for resale the shares underlying the pre-funded warrants and generally to cause the applicable registration statements to be declared effective as soon as practicable.
The selling shareholders may sell some, all or none of the common shares that may be issued to them upon exercise of the pre-funded warrants. We refer to these common shares as warrant shares. We do not know how long the selling shareholders will hold the warrant shares before selling them, and we currently have no agreements, arrangements or understandings with the selling shareholders regarding the sale or other disposition of any of the warrant shares. The warrant shares covered hereby may be offered from time to time by the selling shareholders. As a result, we cannot estimate the number of common shares each of the selling shareholders will beneficially own after termination of sales under this prospectus. In addition, each of the selling shareholders may have sold, transferred or otherwise disposed of all or a portion of its common shares since the date on which it provided information for this table.
Beneficial ownership is determined in accordance with the rules of the SEC and includes voting or investment power with respect to our common shares. Generally, a person “beneficially owns” our common shares if the person has or shares with others the right to vote those shares or to dispose of them, or if the person has the right to acquire voting or disposition rights within 60 days.
The information in the table below and the footnotes thereto regarding common shares to be beneficially owned after the offering assumes the exercise and sale of all warrant shares being offered by the selling shareholders under this prospectus. The percentage of shares owned prior to the offering is based on 24,710,080 common shares outstanding as of August 17, 2020. The percentage of shares owned after the offering is based on 24,710,080 common shares outstanding as of August 17, 2020 plus the maximum number of shares issuable upon exercise of the pre-funded warrants held by the named selling shareholder. This information has been obtained from the selling shareholders or in Schedules 13G or 13D and other public documents filed with the SEC. The address for the selling shareholders is c/o RTW Investments, LP, 40 10th Avenue, Floor 7, New York, NY 10014.

Each of RTW and Dr. Wong disclaim beneficial ownership of the reported securities held by the Funds, except to the extent of its or his pecuniary interest therein. The number of shares beneficially owned by RTW and the Funds, in the aggregate, is limited by beneficial ownership limitations applicable to the pre-funded warrants held by the Funds, which limit the number of shares RTW and the Funds can beneficially own, following the exercise of such warrants, to a maximum of 9.99% of our outstanding common shares. As a result of such limitations, the number of shares beneficially owned does not include up to an aggregate of 6,655,131 common shares issuable upon exercise of pre-funded warrants held by the Funds.

These dispositions may be at fixed prices, at prevailing market prices at the time of sale, at prices related to the prevailing market price, at varying prices determined at the time of sale, or at negotiated prices.
The selling shareholders may use any one or more of the following methods when disposing of warrant shares or interests therein:

ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;

block trades in which the broker-dealer will attempt to sell the warrant shares as agent, but may position and resell a portion of the block as principal to facilitate the transaction;

purchases by a broker-dealer as principal and resale by the broker-dealer for its own account;

an exchange distribution in accordance with the rules of the applicable exchange;

privately negotiated transactions;

short sales effected after the date the registration statement of which this prospectus is a part is declared effective by the SEC;

through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;

through agreements between broker-dealers and the selling shareholders to sell a specified number of such warrant shares at a stipulated price per share;

a combination of any such methods of sale; and

any other method permitted by applicable law.
The selling shareholders may, from time to time, pledge or grant a security interest in some or all of the warrant shares by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the warrant shares, from time to time, under this prospectus, or under an amendment to this prospectus under Rule 424(b) or other applicable provision of the Securities Act amending the list of selling shareholders to include the pledgee, transferee or other successors in interest as selling shareholders under this prospectus. The selling shareholders also may transfer the warrant shares in other circumstances, in which case the pledgees, transferees or other successors in interest will be the selling beneficial owners for purposes of this prospectus.
In connection with the sale of warrant shares or interests therein, the selling shareholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the warrant shares in the course of hedging the positions they assume. The selling shareholders may also sell our common shares short and deliver these securities to close out their short positions, or loan or pledge the warrant shares to broker-dealers that in turn may sell these securities. The selling shareholders may also enter into options or other transactions with broker-dealers or other financial institutions or the creation of one or more derivative securities that require the delivery to each such broker-dealer or other financial institution of warrant shares offered by this prospectus, which warrant shares such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).
The aggregate proceeds to the selling shareholders from the sale of the warrant shares offered by them will be the purchase price of the warrant shares less discounts or commissions, if any. Each of the selling shareholders reserves the right to accept and, together with its agents from time to time, to reject, in whole or in part, any proposed purchase of warrant shares to be made directly or through agents. We will not receive

The selling shareholders and any underwriters, broker-dealers or agents that participate in the sale of the warrant shares or interests therein may be “underwriters” within the meaning of Section 2(11) of the Securities Act.

To the extent required, the warrant shares to be sold, the names of the selling shareholders, the respective purchase prices and public offering prices, the names of any agents, dealer or underwriter, and any applicable commissions or discounts with respect to a particular offer will be set forth in an accompanying prospectus supplement or, if appropriate, a post-effective amendment to the registration statement that includes this prospectus.
In order to comply with the securities laws of some states, if applicable, the warrant shares may be sold in these jurisdictions only through registered or licensed brokers or dealers. In addition, in some states the warrant shares may not be sold unless it has been registered or qualified for sale or an exemption from registration or qualification requirements is available and is complied with.
We have advised the selling shareholders that the anti-manipulation rules of Regulation M under the Exchange Act may apply to sales of warrant shares in the market and to the activities of the selling shareholders and their affiliates. In addition, to the extent applicable we will make copies of this prospectus (as it may be supplemented or amended from time to time) available to the selling shareholders for the purpose of satisfying the prospectus delivery requirements of the Securities Act.

Item 15. Indemnification of Directors and Officers
Under the Business Corporations Act (Québec), or the QBCA, and our bylaws, we must indemnify our current or former directors and officers, agents or any other persons who act or have acted at our request as a director or officer of a related entity, against all costs, charges and expenses reasonably incurred by such person in connection with any civil, criminal, administrative, investigative or other proceeding in which such person is involved because of his, her or its association with us or such a related entity, provided that such person meets the conditions described below. The QBCA also provides that we must also make an advance payment to such person for costs, charges and expenses reasonably incurred in connection with such a proceeding, provided, however, that such person shall repay such advance payment if he, she or it does not fulfill the conditions described below.
The QBCA provides for such indemnification if the following conditions are met:

the person acted with honesty and loyalty in our interests, or, as the case may be, in the interests of the other entity for which the person acted as director or officer or in a similar capacity at our request;

in the case of a proceeding that is enforced by a monetary penalty, the person had reasonable grounds for believing that his, her or its conduct was lawful; and

the person was not judged by the court to have committed an intentional or gross fault.
In the case of actions by or on our behalf, we may make such advance payments or indemnify such persons against all costs, charges and expenses reasonably incurred by such person in connection with such actions, only if (i) the person fulfills the conditions set forth above and (ii) a court approves such advance payments or indemnification.
The QBCA and our bylaws authorize us to purchase and maintain insurance for the benefit of each of our current or former directors or officers and other agents and each person who acts or acted at our request as a director, officer or other agents or a person acting in a similar capacity, of another entity.
In addition, we have entered, or intend to enter, into separate indemnity agreements with each of our directors and officers pursuant to which we agree to indemnify and hold harmless our directors and officers against any and all liability, loss, damage, cost or expense in accordance with the terms and conditions of the QBCA and our bylaws.
We have purchased and currently intend to maintain insurance on behalf of each and every person who is or was a director or officer of our company against any loss arising from any claim asserted against him or her and incurred by him or her in any such capacity, subject to certain exclusions.

Item 17. Undertakings
The undersigned registrant hereby undertakes:
(a)(1)
To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:
(i)
to include any prospectus required by Section 10(a)(3) of the Securities Act;
(ii)
to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Securities and Exchange Commission (the “SEC”) pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement;
(iii)
to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;
provided, however, that paragraphs (a)(1)(i), (a)(1)(ii) and (a)(1)(iii) of this section do not apply if the registration statement is on Form S-3 and the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the SEC by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 (the “Exchange Act”) that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.
(2)
That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
 

TABLE OF CONTENTS
 
(3)
To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.
(4)
That, for the purpose of determining liability under the Securities Act to any purchaser:
(i)
each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and
(ii)
each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5) or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii) or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which the prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.
(b)
The undersigned registrant undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
(c)
Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers, and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer, or controlling person of the registrant in the successful defense of any action, suit, or proceeding) is asserted by such director, officer, or controlling person of the registrant in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

Dear Sirs/Mesdames:

 

Re: Milestone Pharmaceuticals Inc. – Registration Statement on Form S-3

 

We have acted as Canadian counsel to Milestone Pharmaceuticals Inc. (the “Corporation”), a corporation governed by the Business Corporations Act (Québec), in connection with the preparation of a registration statement on Form S-3 (the “Registration Statement”), including a related prospectus filed with the Registration Statement (the “Prospectus”), covering the registration for resale of up to 6,655,131 common shares of the Corporation (the “Shares”) on behalf of the selling shareholders identified in the Prospectus issuable upon the exercise of certain pre-funded warrants sold to the selling shareholders in a private placement on July 24, 2020 (the “Warrants”).

 

We have examined the Registration Statement, the Prospectus and the Warrants and all such corporate and public records, statutes and regulations and have made such investigations and have reviewed such other documents as we have deemed relevant and necessary and have considered such questions of law as we have considered relevant and necessary in order to give the opinion hereinafter set forth. As to various questions of fact material to such opinions which were not independently established, we have relied upon a certificate of an officer of the Corporation.

 

In reviewing the foregoing documents and in giving this opinion, we have assumed (a) the legal capacity of all individuals, the genuineness of all signatures, the veracity of the information contained therein, the authenticity of all documents submitted to us as originals and the conformity to authentic or original documents of all documents submitted to us as certified, conformed, electronic, photostatic or facsimile copies and (b) the completeness, truth and accuracy of all facts set forth in the official public records, certificates and documents supplied by public officials or otherwise conveyed to us by public officials.

 

We are qualified to practice law in the Province of Québec and this opinion is rendered solely with respect to the Province of Québec and the federal laws of Canada applicable in the Province of Québec.

Where our opinion expressed herein refers to the Shares having been issued as being “fully-paid and non-assessable” common shares of the Corporation, such opinion assumes that all required consideration (in whatever form) has been paid or provided. No opinion is expressed as to the adequacy of any consideration received.

 

We express no opinion to the extent that, notwithstanding the Corporation’s current reservation of the Shares as of the date hereof, future issuances of securities of the Corporation, including the Shares, and/or antidilution adjustments to outstanding securities of the Corporation, including the Warrants, may cause the Warrants to be exercisable for more common shares of the Corporation than the number that then remain authorized but unissued.

 

On the basis of the foregoing, we are of the opinion that the Shares, when issued and paid for upon exercise of the Warrants in accordance with the terms of the Warrants, will be will be validly issued, fully paid and non-assessable.

 

Our opinion is limited to the matters stated herein and no opinion is implied or may be inferred beyond the matters expressly stated. Our opinion is based on these laws as in effect on the date hereof, and we disclaim any obligation to advise you of facts, circumstances, events or developments which hereafter may be brought to our attention and which may alter, affect or modify the opinion expressed herein.

 

We consent to the filing of this opinion as an exhibit to the Registration Statement and to the reference to our firm under the caption “Legal Matters” in the Prospectus.

 

Yours very truly,
