Exhibit 99.3

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

The following unaudited pro forma condensed combined financial statements were prepared in accordance with the regulations of the SEC and give effect to (i) the acquisition of Adgero Biopharmaceuticals Holdings, Inc. (“Adgero”) by Kintara Therapeutic, Inc. (formerly known as Delmar Pharmaceuticals, Inc.) (“Kintara”), which was consummated on August 19, 2020 (the “Merger”), and (ii) the consummation of the first closing under Kintara’s private placement on August 19, 2020, pursuant to which Kintara sold 19,587 shares of Series C-1 convertible preferred shares for gross proceeds of $19.587 million (the “Private Placement”). The unaudited pro forma condensed combined balance sheet as of March 31, 2020 assumes that the Merger took place on March 31, 2020 and combines the historical balance sheets of Kintara and Adgero as of March 31, 2020. The unaudited pro forma condensed combined statement of operations for the nine months ended March 31, 2020 and for the year ended June 30, 2019 assume that the Merger took place as of July 1, 2018, and combine the historical statement of operations of Kintara and Adgero for the nine months ended March 31, 2020 and for the year ended June 30, 2019, respectively. Adgero’s fiscal year end is December 31. Therefore, we have prepared Adgero’s statement of operations for the twelve month period ended June 30, 2019 and for the nine month period ended March 31, 2020 to coincide with the fiscal year end of Kintara. The historical financial statements of Kintara and Adgero have been adjusted to give pro forma effect to events that are (i) directly attributable to the merger, (ii) factually supportable, and (iii) with respect to the statements of operations, expected to have a continuing impact on the combined results.

The unaudited pro forma condensed combined financial statements are based on the assumptions and adjustments that are described in the accompanying notes. The unaudited pro forma condensed combined financial statements and pro forma adjustments have been prepared based on preliminary estimates of fair value of assets acquired and liabilities assumed. Differences between these preliminary estimates and the final acquisition accounting will occur and these differences could have a material impact on the accompanying unaudited pro forma condensed combined financial statements and the combined company’s future results of operations and financial position. The actual amounts recorded as of the closing of the Merger may differ materially from the information presented in these unaudited pro forma condensed combined financial statements as a result of the amount, if any, of additional capital raised by Kintara subsequent to the closing of the Merger; the amount of cash used by Adgero’s operations between the signing of the Merger Agreement (as defined below) and the closing of the Merger; the timing of the closing of the Merger; and other changes in the Adgero assets and liabilities that occur prior to the closing of the Merger.

The unaudited pro forma condensed combined financial statements do not give effect to the potential impact of current financial conditions, regulatory matters, operating efficiencies or other savings or expenses that may be associated with the acquisition. The unaudited pro forma condensed combined financial statements have been prepared for illustrative purposes only and are not necessarily indicative of the financial position or results of operations in future periods or the results that actually would have been realized had Kintara and Adgero been a combined company during the specified period. The unaudited pro forma condensed combined financial statements, including the notes thereto, should be read in conjunction with the Kintara historical audited financial statements for the years ended June 30, 2019 and 2018 and unaudited condensed interim financial statements for the nine months ended March 31, 2020 and the Adgero historical audited financial statements for the years ended December 31, 2019 and 2018, and unaudited condensed interim financial statements for the three months ended March 31, 2020.

Notes to the Unaudited Pro Forma Condensed Combined Financial Information

1. Description of Transaction

Merger with Adgero

On June 9, 2020, Kintara, Adgero and a wholly-owned subsidiary of Kintara (“Merger Sub”) entered into a Merger Agreement among Kintara, Adgero and Merger Sub (the “Merger Agreement). Upon the terms and subject to the satisfaction or waiver of the conditions set forth in the Merger Agreement, including approval of the transaction by Kintara’s stockholders and Adgero’s stockholders, Merger Sub will merge with and into Adgero, with Adgero becoming a wholly-owned subsidiary of Kintara and the surviving corporation in the transaction. The transaction has been approved by stockholders for both Kintara and Adgero, respectively, and closed on August 19, 2020.

The unaudited pro forma condensed combined financial information was prepared using the acquisition method of accounting under U.S. GAAP. For accounting purposes, Kintara is considered to be acquiring Adgero and the transaction is expected to be accounted for as an asset acquisition. Kintara is considered the accounting acquirer and Adgero is considered the acquiree in the transaction. To determine the accounting for this transaction under U.S. GAAP, a company must assess whether an integrated set of assets and activities should be accounted for as an acquisition of a business or an asset acquisition. The guidance requires an initial screen test to determine if substantially all of the fair value of the gross assets acquired is concentrated in a single asset or group of similar assets. If that screen is met, the set is not a business. In connection with the acquisition, Adgero does not have an organized workforce that significantly contributes to its ability to create output, and substantially all of its fair value is concentrated in cash and in-process research and development (“IPR&D”). As such, the acquisition is expected to be treated as an asset acquisition.

Adgero’s assets and liabilities will be measured and recognized as an allocation of the transaction price based on their relative fair values as of the transaction date with any value associated with IPR&D being expensed as it has no alternative future use.

Kintara will be deemed to be the accounting acquirer for financial reporting purposes. This determination is based on the expectations that, immediately following the transaction: (i) Kintara stockholders will own a majority of the voting rights of the combined organization; (ii) Kintara will designate a majority (four of seven) of the initial members of the board of directors of the combined organization; and (iii) Kintara’s senior management will hold the majority of the key positions in senior management of the combined organization.

At the closing of the Merger, each share of Adgero Common Stock and Adgero Warrants outstanding immediately prior to the closing of the Merger will be converted into the right to receive a number of shares of Kintara Common Stock and warrants to receive that number of shares of Kintara Common Stock equal to the Exchange Ratio. For purposes of preparing these unaudited pro forma combined financial statements, the Exchange Ratio was 1.5740 shares of Kintara Common Stock for every one share of Adgero Common Stock. In conjunction with the execution of the Merger Agreement, Kintara will issue to SternAegis Ventures a success fee payable in Kintara Common Stock equal to 5% of the number of shares of Kintara Common Stock issued to Adgero stockholders upon the consummation of the Merger Agreement (the “SternAegis Ventures Success Fee Shares”).

Private Placement

On August 19, 2020, Kintara completed the first closing of its Series C Preferred Stock by issuing 19,587 shares of its Series C-1 Convertible Preferred Stock (the “Preferred Stock”) at a purchase price of $1,000 per share in a private placement offering priced at-the-market under the rules of the Nasdaq Stock Market. The Preferred Stock is convertible into shares of Kintara Common Stock at a conversion price of $1.16 per share. Net proceeds from the Private Placement are estimated to be $16,821 after agent commissions and expenses, and additional legal and accounting costs. Kintara also issued placement agent warrants to SternAegis Ventures equivalent to 10% of the number of shares of Preferred Stock issued, or 1,959 placement agent warrants, at an estimated fair value of $637. The placement agent warrants are exercisable at $1.16 per share for five years.

Dividends. The Preferred Stock will be entitled to receive dividends, payable in shares of Kintara Common Stock at a rate of 10%, 15%, 20% and 25% of the number of shares of Kintara Common Stock issuable upon conversion of the Preferred Stock, on the 12th, 24th, 36th and 48th month, anniversary of the initial closing of the Private Placement to occur in connection with the closing of the Merger. Dividends will be payable in shares of Kintara Common Stock and will only be payable to those holders that continue to hold the Preferred Stock on the respective anniversary dates of the initial closing of the Private Placement. In addition, each holder of Preferred Stock will be entitled to receive dividends equal, on an as-converted to shares of Kintara Common Stock basis, to and in the same form as dividends actually paid on shares of Kintara Common Stock when, as, and if such dividends are paid on shares of Kintara Common Stock. Kintara has not ever paid dividends on shares of Kintara Common Stock and does not intend to do so for the foreseeable future.

Conversion. Upon the earlier of (i) the four year anniversary of the initial closing of the Private Placement to occur in connection with the Closing of the Merger or (ii) the consent to conversion by holders of at least 50.1% of all of the then-outstanding shares of Series C Preferred Stock, as a whole, without any action on the part of the holder (each of the foregoing, a “Mandatory Conversion Date”), each share of Series C Preferred Stock will automatically convert into shares of Kintara Common Stock (a “Mandatory Conversion”) at the Conversion Price. In addition, each share of Series C Preferred Stock will be convertible, at any time and from time to time at the option of the holder, into that number of shares of Kintara Common Stock at the Conversion Price.

2. Basis of Pro Forma Presentation

The accompanying unaudited pro forma combined financial information was prepared in accordance with Article 11 of SEC Regulation S-X. The unaudited pro forma combined balance sheet as of March 31, 2020 was prepared using the historical balance sheets of Kintara as of March 31, 2020 and Adgero as of March 31, 2020 and gives effect to the Merger as if it occurred on March 31, 2020.

The unaudited pro forma combined statements of operations and comprehensive loss for the nine month interim period ended March 31, 2020 was prepared using the historical unaudited financial statements of Kintara for the nine month period ended March 31, 2020 and the historical unaudited financial statements of Adgero for the nine month period ended March 31, 2020. These interim statements give effect to the Merger as if it occurred on July 1, 2019. Adgero’s fiscal year end is December 31. Therefore, we have prepared Adgero’s statement of operations for the twelve month period ended June 30, 2019 and for the nine month period ended March 31, 2020 to coincide with the fiscal year end of Kintara.

The unaudited pro forma combined statements of operations and comprehensive loss for the twelve month period was prepared using the historical audited financial statements of Kintara for the fiscal year ended June 30, 2019 and the historical unaudited financial statements of Adgero for the twelve month period ended June 30, 2019. These annual statements give effect to the Merger as if it occurred on July 1, 2018. As Kintara’s post-closing ownership percentage is fixed at 50.5% of the outstanding shares of the voting stock of the combined company the estimated purchase price that Kintara is paying for Adgero depends upon the price of Kintara Common Stock at the closing.

The cost of the asset acquisition will be allocated to the individual assets acquired or liabilities assumed, based on their relative fair values. Any excess consideration transferred over the fair value of the net assets of Adgero following determination of the actual purchase consideration for Kintara will be reflected as an adjustment to intangible assets that will be expensed as IPR&D. Consequently, the financial statements of Kintara reflect the operations of the acquirer for accounting purposes together with a deemed issuance of shares, equivalent to the shares held by the former stockholders of the legal acquirer and an allocation to intangible assets. The historical financial statements of Kintara, which are contained in Kintara’s annual report on Form 10-K for the year ended June 30, 2019 and quarterly report on Form 10-Q for the nine months ended March 31, 2020, which Kintara previously filed with the SEC, and the unaudited historical financial statements of Adgero for the three months ended March 31, 2020 have been adjusted to give pro forma effect to events that are (i) directly attributable to the Merger, (ii) factually supportable, and (iii) with respect to the statements of operations, expected to have a continuing impact on the combined results. The historical financial statements of Kintara shall become the historical financial statements of the combined organization.

To the extent there are significant changes to the business following the closing of the Merger, the assumptions and estimates set forth in the unaudited pro forma condensed consolidated financial statements could change significantly. Accordingly, the pro forma adjustments are subject to further adjustments as additional information becomes available and as additional analyses are conducted following the closing of the Merger. There can be no assurances that these additional analyses will not result in material changes to the estimates of fair value.

3. Shares of Kintara Common Stock Issued to Adgero Stockholders upon closing of the Merger

The number of shares of Kintara Common Stock that were issued to Adgero stockholders, for purposes of these pro forma financial statements as of March 31, 2020, is calculated pursuant to the terms of the Merger Agreement, using an Exchange Ratio that excludes the impact of the closing of the Private Placement as follows:

4. Adjustments to Unaudited Pro Forma Combined Financial Statements

The unaudited pro forma condensed combined financial statements include pro forma adjustments related to material events occurring subsequent to March 31, 2020 which are not directly attributable to the Merger, but which are significant events that will have an effect on the Merger and the events related to the Merger. The unaudited pro forma combined condensed balance sheet as of March 31, 2020 includes pro forma adjustments that are (1) directly attributable to the Merger and (2) factually supportable. The pro forma adjustments are based on preliminary estimates that could change materially as additional information is obtained, are as follows:
