Neovasc Announces Effective Date of Share Consolidation

VANCOUVER, BC — September 18, 2018 — Neovasc Inc. (“Neovasc” or the “Company”) (NASDAQ: NVCN)(TSX: NVCN), a leader in the development of minimally invasive transcatheter mitral valve replacement technologies and in the development of minimally invasive devices for the treatment of refractory angina, announced today that the Company has filed articles of amendment, effective today, to effect the previously announced share consolidation (reverse stock split) (the “Consolidation”) of its issued and outstanding common shares (the “Common Shares”) on the basis of one (1) post-Consolidation Common Share for every one-hundred (100) pre-Consolidation Common Shares.  The consolidation will reduce the number of Common Shares issued and outstanding from approximately 1,901,639,980 Common Shares to approximately 19,016,405 Common Shares. The Common Shares are expected to commence trading on the Toronto Stock Exchange (the “TSX”) and on the Nasdaq Capital Market on a post-Consolidation basis on or about the opening of trading on September 21, 2018.

The Company’s transfer agent, Computershare Investor Services Inc., has sent a letter of transmittal dated today to the registered holders of Common Shares. The letter of transmittal will contain instructions on how to surrender Common Share certificate(s) representing pre-Consolidation Common Shares to the transfer agent. Shareholders may also obtain a copy of the letter of transmittal by accessing the Company’s SEDAR profile at www.sedar.com or the Company’s EDGAR profile at www.sec.gov. Until surrendered, each certificate representing pre-Consolidation Common Shares will be deemed for all purposes to represent the number of Common Shares to which the holder thereof is entitled as a result of the Consolidation. If shareholders hold their Common Shares through an intermediary and they have questions in this regard, they are encouraged to contact their intermediaries.

The Company’s new CUSIP number is 64065J205 and its new ISIN number is CA64065J2056.

For additional information regarding the Consolidation, please refer to the Company’s Notice of Annual General and Special Meeting of Shareholders and Management Information Circular dated May 2, 2018, which are available on SEDAR at www.sedar.com or EDGAR at www.sec.gov.

This news release contains forward-looking statements within the meaning of the U.S. Private Securities Litigation Reform Act of 1995 and applicable Canadian securities laws regarding the expected trading date of the post-Consolidation Common Shares and the rapidly growing cardiovascular marketplace. Words and phrases such as “expected” and “will”, and similar words or expressions, are intended to identify these forward-looking statements. Forward-looking statements are based on estimates and assumptions made by the Company in light of its experience and its perception of historical trends, current conditions and expected future developments, as well as other factors that the Company believes are appropriate in the circumstances. Many factors and assumptions could cause the Company’s actual results, performance or achievements to differ materially from those expressed or implied by the forward-looking statements, including, without limitation, the substantial doubt about the Company’s ability to continue as a going concern; risks relating to the warrants (the “Warrants”) and senior secured convertible notes (the “Notes”) issued pursuant to the November 2017 underwritten public offering and concurrent private placement (together, the “2017 Financings”), resulting in significant dilution to the Company’s shareholders; risks relating to the Company’s need for significant additional future capital and the Company’s ability to raise additional funding; risks relating to cashless exercise and adjustment provisions in the Warrants and Notes issued pursuant to the 2017 Financings, which could make it more difficult and expensive for the Company to raise additional capital in the future and result in further dilution to investors; risks relating to the sale of a significant number of Common Shares; risks relating to the exercise of Warrants or conversion of Notes issued pursuant to the 2017 Financings, which may encourage short sales by third parties; risks
