EXPLANATORY NOTE
Chemomab Therapeutics Ltd. (the “Company”) is announcing that it will effect a ratio adjustment of its American Depositary Shares (ADSs) to ordinary shares, no par value (“ordinary
shares”), such that the current ratio of one (1) ADS representing twenty (20) ordinary shares will change to a new ratio of one (1) ADS representing eighty (80) ordinary shares (the “Ratio Change”), which Ratio Change will take effect on August 26,
2025. This ratio adjustment will essentially serve as a one-for-four reverse ADS split for ADS holders, requiring no action on their part.
The Company will continue to be traded on the Nasdaq Capital Market under the ticker “CMMB”, with an updated CUSIP
Number of 16385C203. The Bank of New York Mellon, serving as the depositary bank for the Company’s ADS program, will arrange for the exchange of every four existing ADSs held for one new ADS on the effective date. There will be no issuance of new
ADSs in connection with the adjustment. Any fractional shares resulting from the adjustment will be aggregated and the depositary bank will attempt to sell them and distribute the net proceeds to the respective ADS holders.
This Report on Form 6-K is hereby incorporated by reference into Company’s Registration Statements on Form F-3 (File No. 333-275002 and No. 333-281750) and Form S-8 (File No.
333-259489 and No. 333-266868).
