Exhibit 99.1

Bioblast Announces Effectiveness of Five to One Reverse

Split

Ordinary Shares Will Begin Trading on a Split-Adjusted

Basis on September 25, 2017

Tel Aviv, Israel, - September 25, 2017 – Bioblast Pharma Ltd. (NasdaqCM: ORPN), a clinical-stage, orphan disease-focused biotechnology company, announced the effectiveness of a five to one reverse split of its share capital. As previously reported, the reverse split was approved by the Company’s shareholders at an Extraordinary General Meeting of Shareholders of the Company held on September 18, 2017.  

The reverse split is intended to increase the per-share trading price of the Company’s ordinary shares to satisfy the $1.00 minimum bid price requirement for continued listing on the NASDAQ Capital Market. As a result of the reverse split and a related amendment to the Company’s articles of association which is now effective, every five ordinary shares, par value NIS 0.01 per share, shall be consolidated into one ordinary share, par value NIS 0.05. No fractional ordinary shares will be issued as a result of the reverse split and any fractional shares will be rounded up to the nearest whole number.

Trading of the Company’s ordinary shares on the NASDAQ Capital Market will continue, on a split-adjusted basis, with the opening of the market on Monday, September 25, 2017, under new CUSIP number M20156119. Immediately subsequent to the reverse split, there will be approximately 3,342,261 of the Company’s ordinary shares issued and outstanding.

The Company has retained its transfer agent, Vstock Transfer, LLC (“Vstock”), to act as its exchange agent for the reverse split. Vstock will provide shareholders of record as of the effective date a letter of transmittal providing instructions for the exchange of their certificates. Shareholders owning shares via a broker or other nominee will have their positions automatically adjusted to reflect the reverse split, subject to brokers’ particular processes, and will not be required to take any action in connection with the reverse split.

For more information regarding the Company’s reverse split, please refer to the proxy statement filed by the Company with the U.S. Securities and Exchange Commission as an exhibit to its Report on Form 6-K on August 14, 2017.
