Note 1 - General.

Chemomab Therapeutics Ltd. (the “Company") is an Israeli -based company incorporated under the laws of the State of Israel in September 2011. The Company’s registered office is located in Kiryat Atidim, Tel Aviv, Israel. The Company is a clinical-stage biotech company discovering and developing innovative therapeutics for conditions with high-unmet medical need that involve inflammation and fibrosis.

On March 16, 2021, the Company, then known as Anchiano Therapeutics Ltd. (“Anchiano”), completed its merger with Chemomab Ltd., a privately-held Israeli limited company (“Chemomab Ltd.”). Pursuant to the Agreement and Plan of Merger (the “Merger Agreement”) dated as of December 14, 2020, by and among Anchiano, CMB Acquisition Ltd., an Israeli limited company and wholly-owned subsidiary of Anchiano (“Merger Sub”), and Chemomab Ltd., Merger Sub merged with and into Chemomab Ltd., with Chemomab Ltd. being the surviving entity and becoming a wholly owned subsidiary of Anchiano (the “Merger”). Upon consummation of the Merger, the Company changed its name from “Anchiano Therapeutics Ltd.” to “Chemomab Therapeutics Ltd.” and the business conducted by Chemomab Ltd. became primarily the business conducted by the Company.

For accounting purposes, Chemomab Ltd. is considered to have acquired Anchiano based upon the terms of the Merger as well as other factors including: (i) Chemomab Ltd.'s former shareholders owned approximately 90% of the combined Company’s outstanding ordinary shares immediately following the closing of the Merger and (ii) Chemomab Ltd. management holds key management positions of the combined Company. The Merger has been accounted for as an asset acquisition (reverse recapitalization transaction) rather than a business combination, as the assets acquired and the liabilities assumed by Chemomab Ltd. do not meet the definition of a business under accounting principles generally accepted in the United States (“U.S. GAAP”). The net assets acquired in connection with the Merger were recorded at their estimated acquisition date fair market value as of March 16, 2021, the date of completion of the Merger.

Immediately prior to the effective date of the Merger, all preferred shares of Chemomab Ltd. were converted into ordinary shares of Chemomab Ltd. on a one-for-one basis.

In connection with the Merger, and following the effective time of the Merger, the Company effected a reverse share split of the Company’s ordinary shares at a ratio of 4:1 (the “Reverse Split”) and increased the number of ordinary shares underlying each American Depositary Share ("ADS") from 5 to 20. At the effective time of the Merger, each Chemomab Ltd. ordinary share outstanding immediately prior to the effective time of the Merger automatically converted into the right to receive approximately 12.86 ADSs, each representing 20 Anchiano ordinary shares, plus a warrant to purchase ADSs that may become exercisable only under certain circumstances.

The exchange ratio was calculated by a formula that was determined through arms-length negotiations between the Company and Chemomab Ltd. The combined Company assumed all of the outstanding options of Chemomab Ltd., vested and unvested, under the Chemomab Share Incentive Plan (the “2015 Plan”), with such options representing the right to purchase a number of ADSs equal to approximately 12.86 multiplied by the number of Chemomab Ltd. ordinary shares previously represented by such options.

The accompanying unaudited condensed consolidated financial statements and notes to the unaudited condensed consolidated financial statements give retroactive effect to the exchange ratio and the Reverse Split for all periods presented.

The equity structure reflects the legal acquirer's equity structure. The balance sheet has been adjusted to reflect the par value of the outstanding shares of the legal acquirer, including the number of shares issued in the Merger. Any difference is recognized as an adjustment to the additional paid in capital.

Immediately after completion of the Merger, on March 16, 2021, the Company had 8,078,727 ADS issued and outstanding (9,003,357 on a fully diluted basis). In addition, immediately after the Merger, Chemomab Ltd. former shareholders owned approximately 90% of the number of issued and outstanding ordinary shares of the Company and the shareholders of the Company immediately prior to the Merger owned approximately 10% of the number of issued and outstanding ordinary shares of the Company (all on a fully diluted basis).¹

On March 16, 2021, immediately prior to the effectiveness of the Merger, Anchiano had 65,675,904 ordinary shares outstanding (prior to the effect of the Reverse Split) and a market capitalization of $58.7 million. The estimated fair value of the net assets of Anchiano on March 16, 2021, prior to the Merger, was approximately $2.5 million. The fair value of ordinary shares on the Merger closing date, prior to the Merger, was above the fair value of the Company’s net assets. As the Company’s net assets were predominantly composed of cash offset against current liabilities, the fair value of the Company’s net assets as of March 16, 2021, prior to the Merger, is considered to be the best indicator of the fair value and, therefore, the estimated preliminary purchase consideration.

The following table summarizes the net assets acquired based on their estimated fair values as of March 16, 2021, immediately prior to completion of the Merger (in thousands):

Cash and cash equivalents	$	2,427
Asset held for sale		1,000
Prepaid and other assets		236
Accrued liabilities		(1,187	)
Net acquired assets	$	2,476

In connection with the Merger, on March 15, 2021, Anchiano entered into Securities Purchase Agreements with certain purchasers for the issuance and sale by Anchiano in a private placement (the “Private Placement”) of approximately $45.5 million of its ADSs and accompanying warrants to purchase ADSs. The warrants have an exercise price of approximately $17.35 per ADS, expire five years from the date of issuance, and if exercised in full, will provide additional proceeds to the Company of approximately $4.5 million. The Private Placement closed on March 22, 2021.

Pursuant to an Asset Purchase and Assignment Agreement dated as of March 16, 2021, as amended on March 31, 2021, between the Company’s wholly owned subsidiary, Anchiano Therapeutics, Inc., a Delaware corporation (“Anchiano Delaware”) and Kestrel Therapeutics, Inc., a Delaware corporation (“Kestrel”), Anchiano Delaware agreed to sell to Kestrel all of the its rights and obligations in its business to the extent related to the research, development and commercialization of the Compounds and Products (as such terms are defined in the Collaboration and License Agreement entered into as of September 13, 2019, by and between ADT Pharmaceuticals, LLC and Anchiano Delaware), also known as the pan-RAS and PDE10/β-catenin programs. In consideration of the sale and transfer of the Compounds and Products, Kestrel paid the Company a total of $1.0 million.

On April 30, 2021, the Company entered into an At the Market Offering Agreement (the "ATM Agreement") with Cantor Fitzgerald & Co., ("Cantor"). According to the ATM Agreement, the Company may offer and sell, from time to time, its ADSs having an aggregate offering price of up to $75.0 million through Cantor pursuant to the ATM Agreement. From April 30, 2021 through September 30, 2022, the Company sold 699,806 ADSs at an average price of $22.75 per ADS under the ATM Agreement, resulting in gross proceeds of approximately $15.9 million. The offer and sale of ADSs under the ATM Agreement has been registered under the Company’s effective registration statement on Form S-3 (File No. 333-255658), together with a prospectus forming a part thereof, filed with the SEC under the Securities Act of 1933, as amended (the “Securities Act”). Sales, if any, of ADS pursuant to the ATM Agreement may be made in any transactions that are deemed to be “at the market” offerings as defined in Rule 415(a)(4) under the Securities Act. The Company is not obligated to sell any ADSs under the ATM Agreement.

On April 25, 2022, the Company filed with the SEC a prospectus supplement to the above-mentioned registration statement for the issuance and sale of up to $18,125,000 of the Company's ADSs under the ATM Agreement, which is within the $75 million maximum permitted under the ATM Agreement.

Since January 2020, the COVID-19 outbreak has dramatically expanded into a worldwide pandemic creating macro-economic uncertainty and disruption in the business and financial markets. Many countries around the world, including Israel, have been taking measures designated to limit the continued spread of the Coronavirus, including the closure of workplaces, restricting travel, prohibiting assembling, closing international borders and quarantining populated areas. The Company's clinical trial sites have been affected by the COVID-19 pandemic, and as a result, commencement of the enrollment of Company’s clinical trials of CM-101 in PSC was delayed and the enrollment rate has been affected as well. As a result, the Company extended patients recruiting to additional territories with significant recruitment potential. In addition, after enrollment in these trials, patients may drop out of the Company's trials because of the COVID-19 possible implications.

Based on management’s assessment, the extent to which the coronavirus will further impact the Company’s operations will depend on future developments, which are highly uncertain and cannot be predicted with confidence, including the duration and severity of the outbreak, and the actions that may be required to contain the coronavirus or treat its impact. The Company is carefully monitoring the restrictions due to the COVID-19 outbreak and will adjust activities accordingly.

On March 27, 2020 and December 27, 2020, the President of the United States signed and enacted into law the Coronavirus Aid, Relief, and Economic Security Act (CARES Act) and the Consolidated Appropriations Act, 2021 (CAA). Among other provisions, the CARES Act and the CAA provide relief to U.S. federal corporate taxpayers through temporary adjustments to net operating loss rules, changes to limitations on interest expense deductibility, and the acceleration of available refunds for minimum tax credit carryforwards. The CARES Act also includes provisions for a carryback of any net operating loss (NOL) arising in a taxable year beginning after December 31, 2017, and before January 1, 2021, to each of the five taxable years preceding the taxable year in which the loss arises (carryback period).

Chemomab Therapeutics Inc., a wholly owned subsidiary of the Company, filed an application with the US Internal Revenue Service to carryback net operating losses. The Company expects to receive the refund by the end of 2022.
