Galmed Pharmaceuticals Ltd. (the “Company”) is announcing that it will effect a reverse share split of the Company’s ordinary shares at the ratio of 1-for-8, such that each eight (8) ordinary shares, par value NIS 1.80 per share, shall be consolidated into one (1) ordinary share, par value NIS 14.40. The first date when the Company’s ordinary shares will begin trading on the Nasdaq Capital Market after implementation of the reverse split will be Wednesday, August 19, 2026.

Following the implementation of the reverse split, the Company’s authorized share capital shall be comprised of 112,500,000 ordinary shares, par value NIS 14.40 per share. The reverse split will adjust the number of issued and outstanding ordinary shares of the Company from 8,332,518 ordinary shares to and approximately 1,041,565 ordinary shares (subject to any further adjustments based on the treatment of fractional shares).

No fractional ordinary shares will be issued as a result of the reverse split. All fractional ordinary shares will be rounded to the nearest whole ordinary share, such that only shareholders holding fractional consolidated shares of more than one half of one whole share shall be entitled to receive one consolidated share. In addition, a proportionate adjustment will be made to the per share exercise price and the number of shares issuable upon the exercise of all outstanding warrants and options entitling the holders to purchase ordinary shares. The new CUSIP number for the ordinary shares will be M47238205.
