Item 8.01 Other Events.

As previously disclosed, on May 23, 2023, Apexigen, Inc., a Delaware corporation (“Apexigen”), entered into an Agreement and Plan of Merger (the “Merger Agreement”), by and among Apexigen, Pyxis Oncology, Inc., a Delaware corporation (“Pyxis Oncology”) and Ascent Merger Sub Corp., a Delaware corporation and wholly owned subsidiary of Pyxis Oncology (“Merger Sub”), pursuant to which, subject to the terms and conditions set forth therein, Merger Sub will merge with and into Apexigen (the “Merger”), with Apexigen surviving the Merger as a wholly owned subsidiary of Pyxis Oncology. On June 30, 2023, Apexigen filed a definitive proxy statement (the “Proxy Statement”) with the Securities and Exchange Commission (the “SEC”) in connection with the proposed Merger.

As of the date of this Current Report on Form 8-K, various purported Apexigen stockholders have sent demand letters to Apexigen that challenge the disclosures in the Proxy Statement.

While Apexigen believes that the disclosures in the Proxy Statement comply fully with all applicable law and denies the allegations in the demand letters described above, in order to avoid possible expense and nuisance and business delays that may result if any of the demand letters results in litigation, and provide additional information to its stockholders, Apexigen has determined to voluntarily supplement certain disclosures in the Proxy Statement related to allegations made in the demand letters with the supplemental disclosures set forth below (the “Supplemental Disclosures”). Nothing in the Supplemental Disclosures shall be deemed an admission of the legal merit, necessity or materiality under applicable laws of any of the disclosures set forth herein. To the contrary, Apexigen specifically denies all allegations in the demand letters described above that any additional disclosure was or is required or material.

The Supplemental Disclosures do not modify the Exchange Ratio or any other terms of the Merger Agreement, nor do the Supplemental Disclosures affect the timing of the special meeting of Apexigen stockholders (the “Special Meeting”) to be held virtually at 8:00 a.m. (Pacific Time) on August 22, 2023. Apexigen stockholders entitled to vote at the Special Meeting may participate in the Special Meeting via live webcast at www.proxydocs.com/APGN.

The Apexigen board of directors (the “Apexigen Board”) continues to unanimously recommend that its stockholders vote “FOR” the proposals to be voted upon at the Special Meeting described in the Proxy Statement.

The Supplemental Disclosures should be read in conjunction with the disclosures contained in the Proxy Statement, which in turn should be read in its entirety. All page references are to the Proxy Statement and terms used below, unless otherwise defined, shall have the meanings ascribed to such terms in the Proxy Statement. Bold and underlined text indicates language that has been added to a referenced disclosure and stricken-through text shows text being deleted from a referenced disclosure. This Current Report on Form 8-K is incorporated into and amends and/or supplements the Proxy Statement as provided herein. Except as specifically noted in the Supplemental Disclosures below, the Proxy Statement remains unchanged.

Supplemental Disclosures

The eighth paragraph on page 75 under the caption “Background of the Merger” is amended and restated by replacing it with the following:

On December 19, 2022, Apexigen and Party A entered into a mutual non-disclosure agreement. The agreement did not contain a standstill restriction.

The twelfth paragraph on page 79 under the caption “Background of the Merger” is amended and restated by replacing it with the following:

Also on April 11, 2023, Apexigen and Party F entered into a mutual non-disclosure agreement. The agreement did not contain a standstill restriction.

The first paragraph on page 80 under the caption “Background of the Merger” is amended and restated by replacing it with the following:

On April 14, 2023, Apexigen and Party G entered into a mutual non-disclosure agreement. The agreement contained a standstill restriction of twelve months in length, which included a customary ‘fall-away’ provision providing that the standstill obligations terminated following Apexigen entering into a definitive agreement providing for a change of control, like the Merger Agreement, and therefore the mutual non-disclosure agreement did not prevent Party G from making a competing proposal to the Apexigen Board. Also on April 14, 2023, On that same date, Apexigen granted management and team members of Party F access to its virtual data room for the purpose of conducting business and financial due diligence.

The second bullet on page 83 under the caption “Reasons for the Merger” is amended and restated by replacing it with the following:

Participation in the Combined Company. The Apexigen Board’s belief, based in part on a scientific diligence and analysis process conducted by Apexigen’s management and reviewed with the Pyxis Oncology Board, that with respect to Pyxis Oncology’s product pipeline and the potential market opportunity for Pyxis Oncology’s products, that Pyxis Oncology’s product candidates represent a sizeable potential market opportunity, and may create value for the stockholders of the combined company and an opportunity for Apexigen’s stockholders to participate in the potential growth of the combined company. The Apexigen Board was not provided with forward-looking financial projections of Pyxis Oncology’s business or, other than projected net cash balance, forward-looking financial projections of the combined company’s business.

The first sub-bullet under the fifth bullet on page 83 under the caption “Reasons for the Merger” is amended and restated by replacing it with the following:

The Apexigen Board’s belief that the combined company will be able to achieve substantial synergies (including reductions in expenses for directors’ and officers’ liability insurance, public filing compliance, and headcount) and be better positioned to meaningfully accelerate growth initiatives and pursue additional opportunities;

The first paragraph under the caption “Principal Financial Analyses” on page 86 is amended and restated by replacing it with the following:

The following is a summary of the principal financial analyses performed by Ladenburg to arrive at the Opinion. Some of the summaries of financial analyses include information presented in tabular format. In order to fully understand the financial analyses, the tables must be read together with the text of each summary. The tables alone do not constitute a complete description of the financial analyses. Considering the data set forth in the tables without considering the full narrative description of the financial analyses, including the methodologies and assumptions underlying the analyses, could create a misleading or incomplete view of the financial analyses. Ladenburg performed certain procedures, including each of the financial analyses described below and reviewed with the Apexigen Board the assumptions on which such analyses were based and other factors, including the historical and projected financial results of Apexigen and Pyxis Oncology. Ladenburg did not review forward-looking financial projections of Pyxis Oncology’s business or, other than projected net cash balance, forward-looking financial projections of Apexigen’s business or the combined company’s business. As a result, and because Pyxis Oncology is an early clinical stage company, Ladenburg did not perform a discounted cash flow analysis.

The first paragraph under the caption “Analysis of Selected Precedent M&A Transactions” on page 88 is amended and restated by replacing it with the following:

Ladenburg reviewed the financial terms, to the extent the information was publicly available, of the 18 most recent merger transactions of companies in the biopharmaceutical industry, which had a lead candidate in Preclinical or Phase 1 stage of clinical development and focused on oncology space (referred to as the “Selected Precedent M&A Transactions”). Ladenburg determined that these recent transactions were more likely to reflect the relevant financial, economic and market conditions and other circumstances as of the date of the Opinion than transactions that occurred earlier in time. Although the Selected Precedent M&A Transactions were used for comparison purposes, none of the target companies were directly comparable to Pyxis Oncology. In its evaluation, Ladenburg did not exercise any judgement or exclusionary practices to add or remove relevant transactions that fit within such parameters. Accordingly, an analysis of the results of such a comparison was not purely mathematical, but instead involved complex considerations and judgments concerning differences in historical and projected financial and operating characteristics of the companies involved and other factors that could affect the merger value of such companies and Pyxis Oncology to which they were being compared. Ladenburg reviewed the total enterprise values of the target companies (including downstream milestone payments). These transactions, including the date each was closed, were as follows below.

The first paragraph under the caption “Analysis of Precedent Reverse Merger Transactions” on page 89 is amended and restated by replacing it with the following:

Ladenburg reviewed the financial terms, to the extent the information was publicly available, of the 64 most recent qualifying reverse-merger transactions of companies in the biopharmaceutical industry (referred to as the “Selected Precedent Reverse Merger Transactions”). Ladenburg determined that these recent transactions were more likely to reflect the relevant financial, economic and market conditions and other circumstances as of the date of the Opinion than transactions that occurred earlier in time. Although the Selected Precedent Reverse Merger Transactions were used for comparison purposes, none of the target companies were directly comparable to Apexigen. Accordingly, an analysis of the results of such a comparison is not purely mathematical, but instead involved complex considerations and judgments concerning differences in historical and projected financial and operating characteristics of the companies involved and other factors that could affect the merger value of such companies and the Merger to which they were being compared. Ladenburg reviewed the total premium to cash delivered to each target, along with other quantitative metrics. These transactions, including the date each was closed, were as follows below.

The first paragraph under the caption “Analysis of Precedent Strategic Reverse Merger Transactions” on page 91 is amended and restated by replacing it with the following:

Ladenburg reviewed the financial terms, to the extent the information was publicly available, of the 14 most recent qualifying strategically aligned reverse-merger transactions of companies in the biopharmaceutical industry in which the acquiring company continued, to some degree, to develop the programs from the acquired company (referred to as the “Selected Precedent Strategic Reverse Merger Transactions”). Ladenburg determined that these recent transactions were more likely to reflect the relevant financial, economic and market conditions and other circumstances as of the date of the Opinion than transactions that occurred earlier in time. Although the Selected Precedent Strategic Reverse Merger Transactions were used for comparison purposes, none of the target companies were directly comparable to Apexigen. Accordingly, an analysis of the results of such a comparison was not purely mathematical, but instead involved complex considerations and judgments concerning differences in historical and projected financial and operating characteristics of the companies involved and other factors that could affect the merger value of such companies and the Merger to which they are being compared. Ladenburg reviewed the total premium to cash delivered to each target, along with other quantitative metrics. These transactions, including the date each was closed, were as follows below.
