Exhibit 99.1

Can-Fite Announces ADS Ratio Change

PETACH TIKVA, Israel, May 1, 2019 -- Can-Fite BioPharma Ltd. (NYSE American: CANF) (TASE:CFBI), a biotechnology company with a pipeline of proprietary small molecule drugs that address cancer, liver and inflammatory diseases, announced today that the Company will change the ratio of its American Depositary Shares (ADSs) to ordinary shares from one (1) ADS representing two (2) ordinary shares to a new ratio of one (1) ADS representing thirty (30) ordinary shares. The ratio change will be effective on May 10, 2019.

For ADS holders, the ratio change will have the same effect as a one-for-fifteen reverse ADS split. On the effective date, each ADS holder will be required to exchange every fifteen (15) ADSs then held for one (1) new ADS. The Bank of New York Mellon, the depositary bank, will arrange for the exchange of the current ADSs for the new ones. There is no change to the Company's underlying ordinary shares, and the Company’s ADSs will continue to trade on the NYSE American under the symbol "CANF".

No fractional new ADSs will be issued in connection with the change in the ADS ratio. Instead, fractional entitlements to new ADSs will be aggregated and sold by the depositary bank and the net cash proceeds from the sale of the fractional ADS entitlements (after deduction of fees, taxes and expenses) will be distributed to the applicable ADS holders by the depositary bank.

As a result of the change in the ADS ratio, the ADS price is expected to increase proportionally, although the Company can give no assurance that the ADS price after the change in the ADS ratio will be equal to or greater than fifteen times the ADS price before the change.
