Exhibit 99.1

Collplant Petitions Court to Voluntarily Delist Ordinary Shares from the Tel Aviv Stock Exchange

Ness Ziona, April 16, 2018, CollPlant (NASDAQ:CLGN, TASE:CLGN), a regenerative medicine company utilizing its proprietary plant-based rhCollagen technology for tissue repair products (recombinant human, “rhCollagen”), announced that it petitioned the District Court of Tel Aviv to approve the convening of a special general meeting of its shareholders for the purpose of obtaining shareholder approval to voluntarily delist the Company’s ordinary shares from the Tel Aviv Stock Exchange (TASE), while maintaining a continued listing on NASDAQ.

Yehiel Tal, CEO of Collplant, commented: “Delisting from the TASE is the next step in Collplant’s development as the Company becomes more US facing. It is well known that the US capital markets are better equipped to value life science companies, and by having a single listing on NASDAQ, we believe that we will see increased trading volume over time and broader opportunities for accessing the US capital markets, which in turn are expected to bring greater value to our shareholders.”

In addition to petitioning the Court to approve the convening of a special general meeting of its shareholders, the Company also petitioned the Court to approve the convening of a special general meeting of the holders of the Series I and K warrant holders to approve the delisting of the Series I and K warrants from the TASE within three months of the Company’s report regarding the Court’s approval of such delisting, and to reduce the exercise price of the Series I and K warrants, from NIS 2.40 and NIS 1.80, respectively, to NIS 1.20, commencing on the date of the Court’s approval of such delisting.
