PROSPECTUS

APOLLOMICS INC.

SECONDARY OFFERING OF

19,166,666 Class A Ordinary Shares

This prospectus relates to the offer and sale from time to time, by the selling securityholders named in this prospectus (collectively, the “Selling Securityholders”), of up to 19,166,666 Class A ordinary shares, par value $0.0001 per share (each a “Class A Ordinary Share” and such shares that may be offered and sold by the Selling Securityholders hereunder, the “PIPE Shares”), of Apollomics Inc., a Cayman Islands exempted company (“us,” “we,” “Apollomics” or the “Company”), that were issued to the Selling Securityholders pursuant to subscription agreements entered into on May 6, 2024, by and between Apollomics and the Selling Securityholders (the “Subscription Agreements”).

We are registering the offer and sale of the PIPE Shares to satisfy certain registration rights we have granted. The Selling Securityholders may offer all or part of the PIPE Shares for resale from time to time through public or private transactions, at either prevailing market prices or at privately negotiated prices. The PIPE Shares are being registered to permit the Selling Securityholders to sell such shares from time to time, in amounts, at prices and on terms determined at the time of offering. The Selling Securityholders may sell the PIPE Shares through ordinary brokerage transactions, in underwritten offerings, directly to market makers of our shares or through any other means described in the section entitled “Plan of Distribution” herein. In connection with any sales of the PIPE Shares offered hereunder, the Selling Securityholders, any underwriters, agents, brokers or dealers participating in such sales may be deemed to be “underwriters” within the meaning of the Securities Act of 1933, as amended (the “Securities Act”). We are registering the PIPE Shares for resale by the Selling Securityholders, or their donees, pledgees, transferees, distributees or other successors-in-interest selling the PIPE Shares or interests in the PIPE Shares received after the date of this prospectus from the Selling Securityholders as a gift, pledge, partnership distribution or other transfer.

We will pay certain expenses associated with the registration of the PIPE Shares covered by this prospectus, as described in the section entitled “Plan of Distribution.”

We may amend or supplement this prospectus from time to time by filing amendments or supplements as required. You should read this entire prospectus and any amendments or supplements carefully before you make your investment decision. Our Class A Ordinary Shares and warrants are listed on the Nasdaq Capital Market, (“Nasdaq”) under the trading symbols “APLM” and “APLMW,” respectively. On May 28, 2024, the closing prices for our Class A Ordinary Shares and warrants on Nasdaq were $0.26 per share and $0.01 per warrant, respectively.

We are an “emerging growth company” as defined in the Jumpstart Our Business Startups Act of 2012 and is therefore eligible to take advantage of certain reduced reporting requirements applicable to other public companies.

We are also a “foreign private issuer” as defined in the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and are exempt from certain rules under the Exchange Act that impose certain disclosure obligations and procedural requirements for proxy solicitations under Section 14 of the Exchange Act. In addition, our officers, directors and principal shareholders will be exempt from the

reporting and “short-swing” profit recovery provisions under Section 16 of the Exchange Act. Moreover, we are not required to file periodic reports and financial statements with the SEC as frequently or as promptly as U.S. companies whose securities are registered under the Exchange Act.

We are a holding company incorporated in the Cayman Islands with our headquarters in the United States. Our operations are conducted in such U.S. headquarters and in one of our wholly-owned subsidiaries in mainland China. Throughout this prospectus, unless the context indicates otherwise, (1) references to “Apollomics,” “we” or “us” refer to Apollomics Inc., the registrant and the Cayman Islands holding company that is the current holding company of the group, (2) references to “Apollomics US” refer to Apollomics Inc. (formerly known as CBT Pharmaceuticals, Inc.), a California corporation, and the headquarters and a wholly-owned subsidiary of Apollomics, (3) references to “Maxpro” refer to Maxpro Capital Acquisition Corp., a Delaware corporation, a blank check company which has become a wholly-owned subsidiary of Apollomics as a result of our business combination with Maxpro, (4) references to “Apollomics AU” refer to Apollomics (Australia) Pty Ltd (formerly known as CBT Pharmaceuticals (Australia) Pty Ltd), an Australian proprietary company registered in Victoria, Australia and a wholly-owned subsidiary of Apollomics, and (5) references to “Apollomics HK” refer to Apollomics (Hong Kong) Limited, a limited company incorporated under the laws of Hong Kong, a wholly owned subsidiary of Apollomics, and the intermediary holding company of Apollomics’ two wholly-owned subsidiaries based in mainland China, Zhejiang Crownmab Biotech Co. Ltd. (“Crownmab”) and Zhejiang Crown Bochuang Biopharma Co. Ltd. (“Crown Bochuang,” together with Crownmab, the “PRC Subsidiaries”). Apollomics US and Crownmab conduct Apollomics’ daily business operations. Unlike some other companies with operating subsidiaries in China, our corporate structure does not contain any variable interest entities (“VIEs”), and we have no intention of establishing or utilizing any VIEs in China in the future. As a result, the accompanying prospectus has neither a description of a VIE structure sometimes associated with companies with operations in China nor does it describe the risks associated with such a corporate structure. For a diagram depicting Apollomics’ corporate structure, see “Prospectus Summary-Overview-Structure of Apollomics.”

Investors in our securities are investing in a Cayman Islands holding company rather than securities of our operating subsidiaries. Such structure involves unique risks to investors. In particular, because some of our operations are conducted in mainland China through the PRC Subsidiaries, we may face various legal and operational risks associated with doing business in Greater China (as defined in this prospectus). These risks arise from, among other things, the People’s Republic of China (the “PRC”) governmental authorities’ significant oversight and discretion over the business and financing activities of the PRC Subsidiaries, the complex and evolving PRC legal system, frequent changes in laws, regulations and government policies, uncertainties and inconsistencies regarding the interpretation and enforcement of laws and regulations, potential difficulties or delays in obtaining necessary regulatory approvals, and increasing oversight on cybersecurity and data privacy and potential anti-monopoly actions related to the PRC government’s recently issued statements and instituted regulatory actions. Recently, the PRC government initiated a series of regulatory actions and made a number of public statements on the regulation of business operations in the PRC with little advance notice, including adopting new measures to extend the scope of cybersecurity reviews, and expanding efforts in anti-monopoly enforcement. As advised by our PRC counsel, JunHe LLP, we do not believe that we are directly subject to these regulatory actions or statements, as our business does not involve any other type of restricted industry, and neither we nor any of our PRC subsidiaries qualify as a critical information infrastructure operator or has conducted any data processing activities that affect or may affect national security or holds personal information of more than one million users. Because these statements and regulatory actions are new, however, it is highly uncertain how soon the PRC legislative or administrative regulation making bodies will respond to them, or what existing or new laws or regulations will be modified or promulgated, if any, or the potential impact such modified or new laws and regulations will have on the daily business operations of our PRC subsidiaries or their ability to accept foreign investments and the value of our securities. These risks could result in a material change in the operations of our PRC Subsidiaries, limit or hinder their abilities to accept foreign investments, and impact our ability to list on a U.S. or other foreign stock exchange and to offer or continue to offer securities to foreign investors, which could cause the value of our securities to significantly decline or become worthless. For a detailed description of the risks related to our holding company structure and doing business in Greater China, see “Risk Factors-Risks Related to Our Operations in China” in the Annual Report.

We are a Cayman Islands holding company and we may rely to a significant extent on cash transfers from our PRC Subsidiaries. Cash transfers from our PRC Subsidiaries to entities outside of China are subject to PRC

government controls on currency conversion. To the extent cash in our business is in the PRC or a PRC entity, such cash may not be available to fund operations or for other use outside of the PRC due to restrictions and limitations imposed by the governmental authorities on currency conversion, cross-border transactions and cross-border capital flows. Shortages in the availability of foreign currency may temporarily delay the ability of our PRC Subsidiaries to make transfers or other payments to us, or otherwise satisfy their foreign currency denominated obligations. We are also subject to various restrictions on foreign exchange control under current PRC laws and regulations and could be subject to additional restrictions under new PRC laws and regulations that may come into effect in the future.

As of the date of this prospectus, neither we nor any of its subsidiaries have made any dividends or distributions to their respective parent companies or to any investor, and the only transfers of cash among us and our subsidiaries have been from us to our subsidiaries for investments in our subsidiaries and for our subsidiaries’ working capital needs. As of December 31, 2023, we have transferred an aggregate of approximately $164.5 million through regular commercial banks via wire transfer in cash to Apollomics US as a capital injection, cash advanced for working capital purposes and payments for services fees, an aggregate of approximately $13.1 million in cash to Apollomics AU as a capital injection, an aggregate of approximately $20.3 million in cash to Apollomics HK as a capital injection and cash advanced for working capital purposes, and an aggregate of approximately $35.0 million ($10.5 million of which was transferred directly and $24.5 million of which was transferred through Apollomics HK) to our PRC subsidiaries in cash as capital injections. Additionally, as of December 31, 2023, there was a capital reduction in our PRC Subsidiaries resulting in approximately $15 million in cash transferred from our PRC Subsidiaries to us. Other than the above transfers, there have been no transfers of any type of assets among us and our subsidiaries. See Apollomics’ audited historical consolidated financial statements included elsewhere in this prospectus. Any determination to pay dividends will be at the discretion of our board of directors. Currently, we do not anticipate that we would distribute earnings even after we become profitable and generate cash flows from operations. We do not currently have any cash management policy that dictates how funds must be transferred between us and our subsidiaries, or among its subsidiaries. If needed, we may transfer funds to our subsidiaries, including the PRC subsidiaries, by way of capital contributions or loans in accordance with the charter of the relevant subsidiaries and in compliance with applicable local laws and regulations. As an offshore holding company, we may use the proceeds of our offshore fund-raising activities to provide loans or make capital contributions to our subsidiaries, in each case subject to the satisfaction of government reporting, registration and approvals. Loans by us to our PRC subsidiaries to finance their activities cannot exceed statutory limits and must be registered with the local counterpart of the State Administration of Foreign Exchange (“SAFE”) and capital contributions to its subsidiaries in China and Hong Kong are subject to the requirement of making necessary registration with competent governmental authorities in China and Hong Kong, respectively. See “Risk Factors-Risks Related to Our Operations in China” in the Annual Report.

Investing in our securities involves a high degree of risk. See “Risk Factors” beginning on page 13 of this prospectus and other risk factors contained in the documents incorporated by reference herein, including our Annual Report on Form 20-F for the year ended December 31, 2023, for a discussion of information that should be considered in connection with an investment in our securities.

Neither the U.S. Securities and Exchange Commission nor any other regulatory body has approved or disapproved of these securities or determined if this prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

The date of this prospectus is May 29, 2024.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

Some of the statements made in this prospectus and the documents incorporated by reference into this prospectus may constitute forward-looking statements within the meaning of the United States federal securities laws. Forward-looking statements provide our current expectations or forecasts of future events. Forward-looking statements include statements about our expectations, beliefs, plans, goals, objectives, intentions, assumptions and other statements that are not historical facts. Forward-looking statements may be identified by the use of words such as “estimate,” “plan,” “project,” “forecast,” “intend,” “will,” “expect,” “anticipate,” “believe,” “seek,” “target” or other similar expressions that predict or indicate future events or trends or that are not statements of historical matters. These forward-looking statements include, but are not limited to, statements regarding our expectations, hopes, beliefs, intentions or strategies regarding the future including, without limitation, statements regarding: plans for preclinical studies, clinical trials and research and development programs; the anticipated timing of the results from those studies and trials; expectations regarding regulatory approvals, and our expectations with respect to future performance. Forward-looking statements are based on current expectations and assumptions that, while considered reasonable by us and our management, as the case may be, are inherently uncertain. These statements are based on various assumptions, whether or not identified herein, and on the current expectations of our management and are not predictions of actual performance. These forward-looking statements are provided for illustrative purposes only and are not intended to serve as, and must not be relied on by any investor as, a guarantee, an assurance, a prediction or a definitive statement of fact or probability.

This summary is not complete and does not contain all of the information that you should consider before deciding whether to invest in the securities covered by this prospectus. This summary is qualified in its entirety by the more detailed information included in or incorporated by reference into this prospectus.

Overview

Apollomics is a clinical-stage biopharmaceutical company focused on the discovery and development of oncology therapies with the potential to be combined with other treatment options to harness the immune system and target specific molecular pathways to inhibit cancer. Our strategic focus is the development of novel therapies targeting difficult to treat cancers. We use both targeted, immuno-oncology, and other innovative approaches to address a range of cancer indications, such as acute myeloid leukemia, lung cancer, brain cancer, and other solid tumors. Our pipeline includes a variety of cancer treatment programs that utilize tumor inhibitors, cell adhesion inhibitors, immune checkpoint inhibitors, a cancer vaccine, monotherapies, combination therapies or a multi-functional protein with the goals to improve response rates and reduce chemo-resistance and toxicity compared to the current treatment standards. We have adopted a biomarker-driven diagnostic approach for patient screening to increase precision in identifying patients that can potentially benefit from target therapy.

Since our founding in 2015, we have built a pipeline of nine product candidates across 11 programs that focus on oncology, of which six product candidates are in the clinical stage. Our two leading product candidates, vebreltinib (APL-101) and uproleselan (APL-106), have shown initial promising clinical results and are in registration trials.

The product candidates in our pipeline can be categorized into three groups based on their mechanisms of action, each of which contains product candidates at different stages of development: (i) tumor inhibitors; (ii) anti-cancer enhancers; and (iii) immuno-oncology drugs. We believe that having three groups of product candidates with different mechanisms of action will enable us to develop potential synergistic therapies that address unmet needs in cancer treatment.

Our most advanced product candidate is vebreltinib, a potent, oral active, highly selective c-Met inhibitor. Our anti-cancer enhancer product candidates include uproleselan and are antagonists of a cell adhesion receptor called E-selectin.

Prior to commercialization of our product candidates in the United States, we must successfully complete nonclinical laboratory and animal tests and submit an investigational new drug application (“IND”) to the U.S. Food and Drug Administration (the “FDA”), which must become effective before clinical testing may commence in the United States. Adequate and well-controlled clinical trials must establish the safety and effectiveness of each product candidate for each indication for which FDA approval is sought. After completion of the required clinical testing, a New Drug Application (“NDA”) or Biologics License Application (“BLA”) is prepared and submitted to the FDA. The NDA or BLA must include the results of all nonclinical, clinical and other testing and a compilation of data relating to the product’s pharmacology, chemistry, manufacture and controls. FDA approval of the NDA or BLA is required before marketing and distribution of the product may begin in the United States.

Our executive offices are located at 989 E. Hillsdale Boulevard, Suite 220, Foster City, California 94404, and its telephone number is (650) 209-4055.

We are a holding company incorporated in the Cayman Islands with our headquarters in the United States. We conduct our operations through Apollomics US, our headquarters based in California, U.S., as well as Crownmab, one of our wholly-owned subsidiaries in the PRC. Investments in our securities are not purchases of equity securities of these operating subsidiaries in the United States or PRC but instead are purchases of equity securities of a Cayman Islands holding company with no material operations of its own.

Structure of Apollomics

The diagram below depicts a simplified version of the organizational structure of Apollomics.

Apollomics US and Crownmab conduct research and development activities relating to the biologics of oncology to facilitate the discovery and development of product candidates and expand our global presence. Apollomics HK is an intermediary holding company holding Crownmab and Crown Bochuang (via Crownmab), and Apollomics HK has not engaged in any business operations since its establishment. Apollomics AU holds certain intellectual property rights and has engaged vendors for our clinical trial-related activities in Australia, but it does not have any other business operations, employees or office space. Crown Bochuang, a wholly-owned subsidiary of Apollomics and a direct subsidiary of Crownmab in the PRC, has been a contracting party for certain engagements of which the business activities are conducted by Crownmab. Crown Bochuang has not engaged in any operational activities and does not have any employees or office space.

Holding Company Structure and PRC Regulatory Matters

We are a holding company incorporated in the Cayman Islands with our headquarters in the United States. We conduct our operations through Apollomics US, our headquarters based in California, U.S., as well as Crownmab, one of our wholly subsidiaries in the PRC. Investments in our securities are not purchases of equity securities of these operating subsidiaries in the United States or PRC but instead are purchases of equity securities of a Cayman Islands holding company with no material operations of its own. Unlike some other companies with operating subsidiaries in China, our corporate structure does not contain any VIEs, and we have no intention of establishing or utilizing any VIEs in China in the future.

As we conduct a portion of our operations in the Greater China region, and we and our PRC Subsidiaries are subject to PRC laws relating to, among others, restrictions over foreign investments and data security. The PRC government has been seeking to exert more control and impose more restrictions on companies based in mainland China raising capital offshore and such efforts may continue or intensify in the future.

We may rely to a significant extent on cash transfers from our PRC Subsidiaries. Cash transfers from our PRC Subsidiaries to entities outside of China are subject to PRC government controls on currency conversion. To

7

the extent cash in our business is in the PRC or a PRC entity, such cash may not be available to fund operations or for other use outside of the PRC due to restrictions and limitations imposed by the governmental authorities on currency conversion, cross-border transactions and cross-border capital flows. Shortages in the availability of foreign currency may temporarily delay the ability of our PRC Subsidiaries to make transfers or other payments to us, or otherwise satisfy their foreign currency denominated obligations. We are also subject to various restrictions on foreign exchange control under current PRC laws and regulations and could be subject to additional restrictions under new PRC laws and regulations that may come into effect in the future.

For example, our PRC Subsidiaries may pay dividends only out of their accumulated after-tax profits upon satisfaction of relevant statutory conditions and procedures, if any, determined in accordance with PRC accounting standards and regulations; each of the PRC Subsidiaries is required to set aside at least 10% of its after-tax profits each year, if any, to fund certain reserve funds until the total amount set aside reaches 50% of its registered capital; the PRC Subsidiaries are required to complete certain procedural requirements related to foreign exchange control in order to make dividend payments in foreign currencies; a withholding tax, at the rate of 10% or lower, is payable by the PRC Subsidiaries upon dividend remittance; approval from or registration with competent PRC government authorities is required where Renminbi is to be converted into foreign currency and remitted out of mainland China to pay capital expenses, such as the repayment of loans denominated in foreign currencies; loans by us to our PRC Subsidiaries to finance their operations shall not exceed certain statutory limits and must be registered with the local counterpart of the State Administration of Foreign Exchange (the “SAFE”); and any capital contribution from us to our PRC Subsidiaries is required to be registered with the competent PRC government authorities.

As of the date of this prospectus, neither we nor our subsidiaries have made any dividends or distributions to their respective parent companies or to any investor, and the only transfers of cash among us and our subsidiaries have been from us to our subsidiaries for investments in our subsidiaries and for our subsidiaries’ working capital needs. As of December 31, 2023, we have transferred an aggregate of approximately $164.5 million through regular commercial banks via wire transfer in cash to Apollomics US as a capital injection, cash advanced for working capital purposes and payments for services fees, an aggregate of approximately $13.1 million in cash to Apollomics AU as a capital injection, an aggregate of approximately $20.3 million to Apollomics HK in cash as a capital injection and cash advanced for working capital purposes, and an aggregate of approximately $35.0 million ($10.5 million of which was transferred directly and $24.5 million of which was transferred through Apollomics HK) to its PRC subsidiaries in cash as capital injections. Additionally, as of December 31, 2023, there was a capital reduction in our PRC Subsidiaries resulting in approximately $15 million in cash transferred from our PRC Subsidiaries to us. Other than the above transfers, there have been no transfers of any type of assets among us and our subsidiaries. If needed, we may transfer funds to our subsidiaries, including the PRC subsidiaries, by way of capital contributions or loans in accordance with the charter of the relevant subsidiaries and in compliance with applicable local laws and regulations. As an offshore holding company, we may use the proceeds of our offshore fund-raising activities to provide loans or make capital contributions to our subsidiaries, in each case subject to the satisfaction of government reporting, registration and approvals. Loans by Apollomics to our PRC subsidiaries to finance their activities cannot exceed statutory limits and must be registered with the local counterpart of SAFE and capital contributions to its subsidiaries in China and Hong Kong are subject to the requirement of making necessary registration with competent governmental authorities in China and Hong Kong, respectively. Any determination to pay dividends will be at the discretion of our board of directors. Currently, we do not anticipate that we would distribute earnings even after we become profitable and generates cash flows from operations. If we intend to distribute dividends from our PRC Subsidiaries in the future, such subsidiaries will transfer the dividends to Apollomics HK, the intermediary holding company which controls all of Apollomics’ subsidiaries in the PRC, in accordance with PRC laws and regulations, and then Apollomics HK will transfer the dividends all the way up to us, and the dividends will be distributed from us to all shareholders respectively in proportion to the shares they hold, regardless of whether the shareholders are U.S. investors or investors in other countries or regions. The cross-border transfer of funds by PRC Subsidiaries under the direct holding structure must be legal and compliant with relevant PRC laws and regulations. As an offshore company, we are permitted under PRC laws and regulations to provide funding to our subsidiaries in the

8

PRC only through loans or capital contributions, subject to applicable government reporting, registration and approvals. However, loans by us to our PRC subsidiaries to finance their activities cannot exceed statutory limits and must be registered with the local counterpart of SAFE and capital contributions to PRC subsidiaries are subject to the requirement of making necessary registration with competent governmental authorities in the PRC. We may encounter difficulties in our ability to transfer cash between our PRC subsidiaries and other subsidiaries largely due to various PRC laws and regulations imposed on foreign exchange. However, our PRC counsel, JunHe LLP, has advised that, as of the date hereof, except for the relevant statutory conditions and procedures of reserve funds, relevant withholding tax requirements and the procedures for approvals from PRC foreign exchange authorities and banks, the relevant PRC laws and regulations do not impose other limitations on the amount of funds that we can transfer out of the PRC. We do not currently have any cash management policy that dictates how funds shall be transferred between us and our subsidiaries, or among its subsidiaries.

In addition, with respect to their business operations, our PRC Subsidiaries are required to maintain various approvals, licenses and permits to operate the company in accordance with relevant PRC laws and regulations. We believe our PRC Subsidiaries are required to obtain and maintain the following approvals, licenses and permits for the operation of Apollomics: (i) business license for Zhejiang Crownmab Biotech Co., Ltd.; (ii) business license for Zhejiang Crown Bochuang Biopharma Co., Ltd., and (iii) business license for Zhejiang Crownmab Biotech Co., Ltd. Shanghai Branch. As of the date of this prospectus, our subsidiaries have obtained and are maintaining all such requisite approvals, licenses and permits for their operations, and none of such requisite permissions or approvals have been denied.

See “Risk Factors-Risks Related to Our Operations in China” in the Annual Report.

Foreign Private Issuer

We are considered a “foreign private issuer” under U.S. securities law. As a “foreign private issuer,” we are subject to different U.S. securities laws than domestic U.S. issuers. The rules governing the information that we must disclose differ from those governing U.S. corporations pursuant to the Exchange Act. We are exempt from the rules under the Exchange Act prescribing the furnishing and content of proxy statements to shareholders. Those proxy statements are not expected to conform to Schedule 14A of the proxy rules promulgated under the Exchange Act. Moreover, we are not required to file periodic reports and financial statements with the SEC as frequently or within the same time frames as U.S. companies with securities registered under the Exchange Act, although it may elect to file certain periodic reports and financial statements with the SEC on a voluntary basis on the forms used by U.S. domestic issuers. We are not required to comply with Regulation FD, which imposes restrictions on the selective disclosure of material information to shareholders. In addition, our officers, directors and principal shareholders are exempt from the reporting and short-swing profit recovery provisions of Section 16 of the Exchange Act and the rules under the Exchange Act with respect to their purchases and sales of our securities.

Emerging Growth Company

We are an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012, or the JOBS Act, and we may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved.

Risks Related to Ownership of Apollomics Securities

Sales of a substantial number of our securities in the public market by the Selling Securityholders and/or by our existing securityholders could cause the price of our Class A Ordinary Shares and warrants to fall.

The Selling Securityholders can resell under this prospectus up to 19,166,666 Class A Ordinary Shares constituting approximately 17.6% of our total issued and outstanding Class A Ordinary Shares. The securities being offered in this prospectus represent a substantial percentage of our issued and outstanding Class A Ordinary Shares, and the sale of such securities in the public market by the Selling Securityholders, or the perception that those sales might occur, could depress the market price of our Class A Ordinary Shares and warrants and could impair our ability to raise capital through the sale of additional equity securities. We are unable to predict the effect that such sales may have on the prevailing market price of our Class A Ordinary Shares and warrants.

Risks Related to the U.S. Federal Income Tax

The IRS may not agree that we should be treated as a non-U.S. corporation for U.S. federal income tax purposes.

A corporation is generally considered for U.S. federal income tax purposes to be a tax resident in the jurisdiction of its organization and incorporation. Accordingly, under generally applicable U.S. federal income tax rules, as we are incorporated under the laws of the Cayman Islands, we would be classified as a non-U.S. corporation (and, therefore, not a U.S. tax resident) for U.S. federal income tax purposes. Section 7874 of the U.S. Internal Revenue Code of 1986, as amended (the “Code”), provides an exception to this general rule, under which a non-U.S. incorporated entity may, in certain circumstances, be treated as a U.S. corporation for U.S. federal income tax purposes.

We do not currently expect to be treated as a U.S. corporation for U.S. federal income tax purposes under Section 7874 of the Code as a result of the Business Combination. However, the application of Section 7874 of the Code is complex, is subject to detailed rules and regulations (the application of which is uncertain in various respects, and could be impacted by changes in such rules and regulations, with possible retroactive effect). Accordingly, there can be no assurance that the IRS will not challenge our status as a foreign corporation under Section 7874 of the Code or that such challenge would not be sustained by a court.

If the IRS were to successfully challenge our status as a foreign corporation for U.S. federal income tax purposes under Section 7874 of the Code, we and certain of our shareholders would be subject to significant adverse tax consequences, including a higher effective corporate income tax rate on us and future withholding taxes on certain of our shareholders, depending on the application of any income tax treaty that might apply to reduce such withholding taxes.

Investors should consult their own tax advisors regarding the potential application of Section 7874 of the Code to us.

13

If we were characterized as a passive foreign investment company, or “PFIC,” U.S. investors may suffer adverse U.S. federal income tax consequences.

If we become a PFIC for any taxable year (or portion thereof) that is included in the holding period of a U.S. Holder (as defined in “Taxation—Certain U.S. Federal Income Tax Considerations”) of our securities, the U.S. Holder may be subject to adverse U.S. federal income tax consequences and may be subject to additional reporting requirements.

We are not expected to be treated as a PFIC for U.S. federal income tax purposes for our current taxable year or in the foreseeable future. Nevertheless, whether we are treated as a PFIC for U.S. federal income tax purposes for any taxable year is a factual determination that can only be made after the close of such taxable year and, thus, is subject to significant uncertainty and change. Accordingly, there can be no assurances with respect to our status as a PFIC for our current taxable year or any subsequent taxable year. In addition, our U.S. counsel expresses no opinion with respect to our PFIC status for any taxable year. U.S. investors are urged to consult their own tax advisors regarding the possible application of the PFIC rules to their investment in us.

SELLING SECURITYHOLDERS

This prospectus relates to the possible resale by the Selling Securityholders of up to 19,166,666 Class A Ordinary Shares.

The Selling Securityholders may offer and sell, from time to time, any or all of the Class A Ordinary Shares being offered for resale pursuant to this prospectus. In this prospectus, the term “Selling Securityholders” includes (i) the entities identified in the table below (as such table may be amended from time to time by means of an amendment to the registration statement of which this prospectus forms a part or by a supplement to this prospectus) and (ii) any donees, pledgees, transferees or other successors-in-interest that acquire any of the securities covered by this prospectus after the date of this prospectus from the named Selling Securityholders as a gift, pledge, partnership distribution or other non-sale related transfer.

The table below sets forth, as of the date of this prospectus, the name of the Selling Securityholders for which we are registering Class A Ordinary Shares for resale to the public, and the aggregate principal amount that the Selling Securityholders may offer pursuant to this prospectus. In accordance with SEC rules, individuals and entities below are shown as having beneficial ownership over shares they own or have the right to acquire within 60 days, as well as shares for which they have the right to vote or dispose of such shares. Also in accordance with SEC rules, for purposes of calculating percentages of beneficial ownership, shares which a person has the right to acquire within 60 days are included both in that person’s beneficial ownership as well as in the total number of shares issued and outstanding used to calculate that person’s percentage ownership but not for purposes of calculating the percentage for other persons. In some cases, the same Class A Ordinary Shares are reflected more than once in the table below because more than one holder may be deemed the beneficial owner of the same Class A Ordinary Shares. We have based percentage ownership on 108,662,456 Class A Ordinary Shares outstanding as of the date of this prospectus.

Because each Selling Securityholder may dispose of all, none or some portion of their securities, no estimate can be given as to the number of securities that will be beneficially owned by a Selling Securityholder upon termination of this offering. For purposes of the table below, however, we have assumed that after termination of this offering none of the securities covered by this prospectus will be beneficially owned by the Selling Securityholder and further assumed that the Selling Securityholders will not acquire beneficial ownership of any additional securities during the offering. In addition, the Selling Securityholders may have sold, transferred or otherwise disposed of, or may sell, transfer or otherwise dispose of, at any time and from time to time, our securities in transactions exempt from the registration requirements of the Securities Act after the date on which the information in the table is presented. Please see the section titled “Plan of Distribution” for further information regarding the Selling Securityholders’ method of distributing these securities.

Unless otherwise indicated, the business address of each beneficial owner listed in the tables below is c/o Apollomics Inc., 989 E. Hillsdale Blvd., Suite 220, Foster City, California, United States, 94404.

PLAN OF DISTRIBUTION

The Selling Securityholders, which as used here includes donees, pledgees, transferees or other successors-in-interest selling Class A Ordinary Shares or interests in Class A Ordinary Shares received after the date of this prospectus from a Selling Securityholder as a gift, pledge, partnership distribution or other transfer, may, from time to time, sell, transfer or otherwise dispose of any or all of their Class A Ordinary Shares or interests in Class A Ordinary Shares on any stock exchange, market or trading facility on which the Class A Ordinary Shares are traded or in private transactions. These dispositions may be at fixed prices, at prevailing market prices at the time of sale, at prices related to the prevailing market price, at varying prices determined at the time of sale, or at negotiated prices.

The Selling Securityholders may use any one or more of the following methods when disposing of Class A Ordinary Shares or interests therein:

The Selling Securityholders may, from time to time, pledge or grant a security interest in some or all of the Class A Ordinary Shares owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the Class A Ordinary Shares, from time to time, under this prospectus. The Selling Securityholders also may transfer the Class A Ordinary Shares in other circumstances, in which case the transferees, pledgees or other successors in interest will be the selling beneficial owners for purposes of this prospectus.

In connection with the sale of our Class A Ordinary Shares or interests therein, the Selling Securityholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the Class A Ordinary Shares in the course of hedging the positions they assume. The Selling Securityholders may also sell Class A Ordinary Shares short and deliver these securities to close out their short positions, or loan or pledge the Class A Ordinary Shares to broker-dealers that in turn may sell these securities. The Selling Securityholders may also enter into option or other transactions with broker-dealers or other financial institutions or the creation of one or more derivative securities which require the delivery to such broker-dealer or other financial institution of Class A Ordinary Shares offered by this prospectus, which Class A Ordinary Shares such broker-dealer or other financial institution may resell pursuant to this prospectus.

The Selling Securityholders may also sell securities under Rule 144 under the Securities Act, if available, or in other transactions exempt from registration. Each of the Selling Securityholders reserves the right to accept

21

and, together with their agents from time to time, to reject, in whole or in part, any proposed purchase of Class A Ordinary Shares to be made directly or through agents. We will not receive any of the proceeds from this offering.

The Selling Securityholders and any underwriters, broker-dealers or agents that participate in the sale of Class A Ordinary Shares or interests therein may be “underwriters” within the meaning of Section 2(11) of the Securities Act. Any discounts, commissions, concessions or profit they earn on any resale of the shares may be underwriting discounts and commissions under the Securities Act. Selling securityholders who are “underwriters” within the meaning of Section 2(11) of the Securities Act will be subject to the prospectus delivery requirements of the Securities Act.

In addition, a Selling Securityholder that is an entity may elect to make a pro rata in-kind distribution of securities to its members, partners or stockholders pursuant to the registration statement of which this prospectus is a part by delivering a prospectus with a plan of distribution. Such members, partners or stockholders would thereby receive freely tradeable securities pursuant to the distribution through a registration statement.

To the extent required, the Class A Ordinary Shares to be sold, the names of the Selling Securityholders, the respective purchase prices and public offering prices, the names of any agents, dealer or underwriter, any applicable commissions or discounts with respect to a particular offer will be set forth in an accompanying prospectus supplement or, if appropriate, a post-effective amendment to the registration statement that includes this prospectus.

In order to comply with the securities laws of some states, if applicable, the Class A Ordinary Shares may be sold in these jurisdictions only through registered or licensed brokers or dealers. In addition, in some states the Class A Ordinary Shares may not be sold unless they have been registered or qualified for sale or an exemption from registration or qualification requirements is available and is complied with.

In addition, to the extent applicable we will make copies of this prospectus (as it may be supplemented or amended from time to time) available to the Selling Securityholders for the purpose of satisfying the prospectus delivery requirements of the Securities Act. The Selling Securityholders may indemnify any broker-dealer that participates in transactions involving the sale of securities against certain liabilities, including liabilities arising under the Securities Act.

We have agreed to indemnify certain of the Selling Securityholders against liabilities, including liabilities under the Securities Act and state securities laws, relating to the registration of the Class A Ordinary Shares offered by this prospectus.

We have agreed with certain of the Selling Securityholders to keep the registration statement of which this prospectus constitutes a part effective until all of the securities covered by this prospectus have been disposed of pursuant to and in accordance with the registration statement or the securities have been withdrawn.

To the extent required, we will use our best efforts to file one or more supplements to this prospectus to describe any material information with respect to the plan of distribution not previously disclosed in this prospectus or any material change to such information.

TAXATION

Certain U.S. Federal Income Tax Considerations

The following discussion is a summary of certain material U.S. federal income tax considerations to U.S. Holders (as defined below) of the ownership and disposition of our Class A Ordinary Shares that are being offered pursuant to this prospectus. This discussion applies only to U.S. Holders that hold the Class A Ordinary Shares, as the case may be, as “capital assets” within the meaning of Section 1221 of the Code (generally, property held for investment). The following does not purport to be a complete analysis of all potential tax effects arising in connection with the ownership and disposition of our Class A Ordinary Shares. The effects of U.S. federal tax laws other than U.S. federal income tax laws, such as estate and gift tax laws, and U.S. state, local and non-U.S. tax laws are not discussed.

This discussion does not address all U.S. federal income tax considerations that may be relevant to any particular investor’s particular circumstances, including the impact of the Medicare contribution tax on net investment income and the alternative minimum tax, or to investors subject to special rules under U.S. federal income tax laws, including, without limitation:

If an entity or arrangement treated as a partnership or other pass-through entity for U.S. federal income tax purposes is a beneficial owner of our Class A Ordinary Shares, the tax treatment of a partner, member, or other beneficial owner of such partnership or other pass-through entity will depend on the status of such partner, member, or other beneficial owner, the activities of the partnership or other pass-through entity and certain determinations made at the owner level. Accordingly, partnerships and other pass-through entities and the partners, members, and other beneficial owners of such partnerships and other pass-through entities should consult their tax advisors regarding the U.S. federal income tax consequences to them of the ownership and disposition of our securities.

23

This discussion is based on the Code, U.S. Treasury regulations promulgated thereunder, judicial decisions, and published rulings and administrative pronouncements of the IRS, in each case in effect as of the date hereof. These authorities are subject to change or to differing interpretations. Any such change or differing interpretation may be applied retroactively or otherwise have retroactive effect in a manner that could adversely affect the tax consequences discussed below. We have not sought, and we do not intend to seek, any rulings from the IRS regarding the matters discussed below. There can be no assurance that the IRS will not take, or a court will not sustain, a position contrary to any of the tax considerations discussed below.

THIS DISCUSSION IS ONLY A SUMMARY OF CERTAIN U.S. FEDERAL INCOME TAX CONSIDERATIONS ASSOCIATED WITH THE OWNERSHIP AND DISPOSITION OF OUR CLASS A ORDINARY SHARES. EACH INVESTOR IN THE CLASS A ORDINARY SHARES IS URGED TO CONSULT ITS OWN TAX ADVISOR WITH RESPECT TO THE PARTICULAR TAX CONSEQUENCES TO SUCH INVESTOR OF THE ACQUISITION, OWNERSHIP AND DISPOSITION OF THE CLASS A ORDINARY SHARES, INCLUDING THE APPLICABILITY AND EFFECT OF ANY U.S. FEDERAL, STATE AND LOCAL, AND NON-U.S. TAX LAWS.

For purposes of this discussion, a “U.S. Holder” is a beneficial owner of our Class A Ordinary Shares who or that is, for U.S. federal income tax purposes:

Dividends and Other Distributions on Our Class A Ordinary Shares

Subject to the PFIC rules discussed below under the heading “—Passive Foreign Investment Company Rules,” the gross amount of distributions, i.e., before reduction for withholding taxes, if any, (other than certain distributions of our shares or rights to acquire our shares) on our Class A Ordinary Shares will generally be taxable as a dividend for U.S. federal income tax purposes to the extent paid from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. Such dividends generally will be includable in a U.S. Holder’s income in the year actually or constructively received by such U.S. Holder. Distributions in excess of our current and accumulated earnings and profits will constitute a return of capital that will be applied against and reduce (but not below zero) the U.S. Holder’s adjusted tax basis in its Class A Ordinary Shares. Any remaining excess will be treated as gain realized on the sale or other disposition of the Class A Ordinary Shares and will be treated as described below under the heading “—Gain or Loss on Sale, Taxable Exchange or Other Taxable Disposition of Our Class A Ordinary Shares.”

Amounts treated as dividends that we pay to a U.S. Holder that is treated as a corporation for U.S. federal income tax purposes generally will be taxed at regular rates and will not qualify for the dividends received deduction generally allowed to domestic corporations in respect of dividends received from other domestic corporations. With respect to non-corporate U.S. Holders, under tax laws currently in effect and subject to certain exceptions (including, but not limited to, dividends treated as investment income for purposes of investment interest deduction limitations), dividends generally will be taxed at the lower applicable long-term capital gains rate only if our Class A Ordinary Shares are readily tradable on an established securities market in the United States or we are eligible for benefits under an applicable tax treaty with the United States, and, in each case, we

24

are not treated as a PFIC with respect to such U.S. Holder in the taxable year in which the dividend was paid or in the preceding year and provided certain holding period requirements are met. U.S. Holders should consult their tax advisors regarding the availability of such lower rate for any dividends paid with respect to our Class A Ordinary Shares.

Any amount treated as dividend income generally will be treated as foreign-source dividend income and generally will constitute “passive” category income for computing the foreign tax credit allowable to a U.S. Holder for U.S. federal income tax purposes.

Gain or Loss on Sale, Taxable Exchange or Other Taxable Disposition of Our Class A Ordinary Shares

Subject to the PFIC rules discussed below under the heading “—Passive Foreign Investment Company Rules,” upon any sale, taxable exchange or other taxable disposition of our Class A Ordinary Shares, a U.S. Holder generally will recognize gain or loss in an amount equal to the difference between (i) the amount realized (i.e., sum of the amount of cash and the fair market value of any other property received in such sale, taxable exchange or other taxable disposition, in each case before reduction for withholding taxes, if any) and (ii) the U.S. Holder’s adjusted tax basis in such Class A Ordinary Shares. Any such gain or loss generally will be capital gain or loss and will be long-term capital gain or loss if the U.S. Holder’s holding period for such Class A Ordinary Shares exceeds one year. Long-term capital gain realized by a non-corporate U.S. Holder generally will be taxable at a reduced rate. The deductibility of capital losses is subject to limitations.

Passive Foreign Investment Company Rules

The treatment of U.S. Holders of Class A Ordinary Shares could be materially different from that described above if we are treated as a PFIC for U.S. federal income tax purposes.

A foreign (i.e., non-U.S.) corporation will be classified as a PFIC for U.S. federal income tax purposes if either (i) at least 75% of its gross income in a taxable year, including its pro rata share of the gross income of any corporation in which it is considered to own at least 25% of the shares by value, is passive income or (ii) at least 50% of its assets in a taxable year (ordinarily determined based on fair market value and averaged quarterly over the year), including its pro rata share of the assets of any corporation in which it is considered to own at least 25% of the shares by value, are held for the production of, or produce, passive income. Passive income generally includes dividends, interest, rents and royalties (other than rents or royalties derived from the active conduct of a trade or business) and gains from the disposition of passive assets.

We are not expected to be treated as a PFIC for U.S. federal income tax purposes for our current taxable year or in the foreseeable future. However, whether we are treated as a PFIC for U.S. federal income tax purposes for any taxable year is a factual determination that can only be made after the close of such taxable year and, thus, is subject to significant uncertainty and change. Accordingly, there can be no assurance with respect to our status as a PFIC for our current taxable year or any future taxable year. In addition, our U.S. counsel expresses no opinion with respect to our PFIC status for any taxable year.

Although our PFIC status is determined annually, a determination that we are a PFIC in a particular taxable year will generally apply for subsequent years to a U.S. Holder who held Class A Ordinary Shares while we were a PFIC, whether or not we meet the test for PFIC status in those subsequent years.

If we are determined to be a PFIC for any taxable year (or portion thereof) that is included in the holding period of a U.S. Holder of Class A Ordinary Shares and the U.S. Holder did not make either a qualified electing fund (“QEF”) election or mark-to-market election, as further discussed below, for the first taxable year in which we were treated as a PFIC and in which the U.S. Holder held (or was deemed to hold) such shares or otherwise, such U.S. Holder generally will be subject to special and adverse rules with respect to (i) any gain recognized by the U.S. Holder on the sale or other disposition of its Class A Ordinary Shares (which may include gain realized

25

by reason of transfers of Class A Ordinary Shares that would otherwise qualify as nonrecognition transactions for U.S. federal income tax purposes) and (ii) any “excess distribution” made to the U.S. Holder (generally, any distributions to such U.S. Holder during a taxable year of the U.S. Holder that are greater than 125% of the average annual distributions received by such U.S. Holder in respect of the Class A Ordinary Shares during the three preceding taxable years of such U.S. Holder or, if shorter, the portion of such U.S. Holder’s holding period for the Class A Ordinary Shares that preceded the taxable year of the distribution) (together, the “excess distribution rules”).

Under these excess distribution rules:

In general, if we are determined to be a PFIC, a U.S. Holder may be able to avoid the excess distribution rules described above in respect of our Class A Ordinary Shares by making and maintaining a timely and valid QEF election (if eligible to do so) to include in income its pro rata share of our net capital gains (as long-term capital gain) and other earnings and profits (as ordinary income), on a current basis, in each case whether or not distributed, in the taxable year of the U.S. Holder in which or with which our taxable year ends. A U.S. Holder generally may make a separate election to defer the payment of taxes on undistributed income inclusions under the QEF rules, but if deferred, any such taxes will be subject to an interest charge.

If a U.S. Holder makes a QEF election with respect to its Class A Ordinary Shares in a year after our first taxable year as a PFIC in which the U.S. Holder held (or was deemed to hold) Class A Ordinary Shares, then notwithstanding such QEF election, the excess distribution rules discussed above, adjusted to take into account the current income inclusions resulting from the QEF election, will continue to apply with respect to such U.S. Holder’s Class A Ordinary Shares, unless the U.S. Holder makes a purging election under the PFIC rules. Under one type of purging election, the U.S. Holder will be deemed to have sold such Class A Ordinary Shares at their fair market value and any gain recognized on such deemed sale will be treated as an excess distribution, as described above. As a result of such purging election, the U.S. Holder will have additional basis (to the extent of any gain recognized on the deemed sale) and, solely for purposes of the PFIC rules, a new holding period in the Class A Ordinary Shares.

The QEF election is made on a shareholder-by-shareholder basis and, once made, can be revoked only with the consent of the IRS. A U.S. Holder generally makes a QEF election by attaching a completed IRS Form 8621 (Information Return by a Shareholder of a Passive Foreign Investment Company or Qualified Electing Fund), including the information provided in a PFIC annual information statement, to a timely filed U.S. federal income tax return for the tax year to which the election relates. Retroactive QEF elections generally may be made only by filing a protective statement with such return and if certain other conditions are met or with the consent of the IRS. U.S. Holders should consult their tax advisors regarding the availability and tax consequences of a retroactive QEF election under their particular circumstances.

If a U.S. Holder has made a QEF election with respect to their Class A Ordinary Shares, and the excess distribution rules discussed above do not apply to such shares (because of a timely QEF election for our first

26

taxable year as a PFIC in which the U.S. Holder holds (or is deemed to hold) such shares or a purge of the PFIC taint pursuant to a purging election, as described above), any gain recognized on the sale of Class A Ordinary Shares generally will be taxable as capital gain and no additional interest charge will be imposed under the PFIC rules. As discussed above, if we were a PFIC for any taxable year, a U.S. Holder of Class A Ordinary Shares that has made a QEF election will be currently taxed on its pro rata share of our earnings and profits, whether or not distributed for such year. A subsequent distribution of such earnings and profits that were previously included in income generally should not be taxable when distributed to such U.S. Holder. The tax basis of a U.S. Holder’s shares in a QEF will be increased by amounts that are included in income, and decreased by amounts distributed but not taxed as dividends, under the above rules. In addition, if we were not a PFIC for any taxable year, such U.S. Holder will not be subject to the QEF inclusion regime with respect to its Class A Ordinary Shares for such a taxable year.

In order to comply with the requirements of a QEF election, a U.S. Holder must receive a PFIC Annual Information Statement from us that provides the information necessary for U.S. Holders to make or maintain a QEF election. If we determine that we are a PFIC for any taxable year, upon written request, we will endeavor to provide to such requesting U.S. Holder a PFIC Annual Information Statement as may be required in order to enable the U.S. Holder to make and maintain a QEF election with respect to us, but there is no assurance that we will timely provide such required information. There is also no assurance that we will have timely knowledge of our status as a PFIC in any particular taxable year or of the required information to be provided.

Alternatively, if we are a PFIC and our Class A Ordinary Shares constitute “marketable stock,” a U.S. Holder who owns (or is treated as owning for purposes of this rule) our shares at the close of its taxable year may avoid the application of the excess distribution rules discussed above if such U.S. Holder makes a “mark-to-market” election with respect to such shares for the first taxable year in which it holds (or is deemed to hold) Class A Ordinary Shares and for which we are determined to be a PFIC. Such U.S. Holder generally will include for each of its taxable years as ordinary income the excess, if any, of the fair market value of its Class A ordinary shares at the end of such year over its adjusted basis in its Class A Ordinary Shares. The U.S. Holder also will recognize an ordinary loss in respect of the excess, if any, of its adjusted basis of its Class A Ordinary Shares over the fair market value of its Class A Ordinary Shares at the end of its taxable year (but only to the extent of the net amount of previously included income as a result of the mark-to-market election). The U.S. Holder’s basis in its Class A Ordinary Shares will be adjusted to reflect any such income or loss amounts, and any further gain recognized on a sale or other taxable disposition of its Class A Ordinary Shares will be treated as ordinary income and any further loss recognized will be treated as ordinary loss (but only to the extent of the net amount of income previously included as a result of a mark-to-market election, and any loss in excess of such prior inclusions generally would be treated as capital loss).

The mark-to-market election is available only for “marketable stock,” generally, stock that is regularly traded on a national securities exchange that is registered with the Securities and Exchange Commission, including Nasdaq, or on a foreign exchange or market that the IRS determines has rules sufficient to ensure that the market price represents a legitimate and sound fair market value. If made, a mark-to-market election would be effective for the taxable year for which the election was made and for all subsequent taxable years unless the Class A Ordinary Shares cease to qualify as “marketable stock” for purposes of the PFIC rules or the IRS consents to the revocation of the election. U.S. Holders are urged to consult their tax advisors regarding the availability and tax consequences of a mark-to-market election with respect to Class A Ordinary Shares under their particular circumstances.

If we are a PFIC and, at any time, we have a foreign subsidiary that is classified as a PFIC, a U.S. Holder generally would be deemed to own a proportionate amount of the shares of such lower-tier PFIC, and generally could incur liability for the deferred tax and interest charge under the excess distribution rules described above if we receive a distribution from, or disposes of all or part of its interest in, the lower-tier PFIC, or the U.S. Holder otherwise was deemed to have disposed of an interest in the lower-tier PFIC. There can be no assurance that we will have timely knowledge of the status of any lower-tier PFIC or provide information that may be required for

27

a U.S. Holder to make or maintain a QEF election with respect to such lower-tier PFIC. A mark-to-market election generally would not be available with respect to such lower-tier PFIC.

A U.S. Holder that owns (or is deemed to own) shares in a PFIC during any taxable year of the U.S. Holder, may have to file an IRS Form 8621 (whether or not a QEF or mark-to-market election is made) and to provide such other information as may be required by the U.S. Treasury Department. Failure to do so, if required, will extend the statute of limitations applicable to such U.S. Holder until such required information is furnished to the IRS.

The rules dealing with PFICs and with the QEF, purging and mark-to-market elections are very complex and are affected by various factors in addition to those described above. Accordingly, U.S. Holders of our Class A Ordinary Shares are urged to consult their own tax advisors concerning the application of the PFIC rules to our securities under their particular circumstances.

Foreign Asset Reporting

Certain U.S. Holders may be required to file an IRS Form 926 (Return by a U.S. Transferor of Property to a Foreign Corporation) to report a transfer of property (including cash) to us. Substantial penalties may be imposed on a U.S. Holder that fails to comply with this reporting requirement, and the period of limitations on assessment and collection of U.S. federal income taxes will be extended in the event of a failure to comply. Furthermore, certain U.S. Holders are required to report their holdings of certain specified foreign financial assets, including equity of foreign entities, if the aggregate value of all of these assets exceeds certain threshold amounts, by filing IRS Form 8938 with their federal income tax return. Our Class A Ordinary Shares are expected to constitute foreign financial assets subject to these requirements unless the Class A Ordinary Shares are held in an account maintained at certain financial institutions. Persons who are required to report specified foreign financial assets and fail to do so may be subject to substantial penalties, and the period of limitations on assessment and collection of U.S. federal income taxes may be extended in the event of a failure to comply. U.S. Holders are urged to consult their tax advisors regarding their information reporting obligations, if any, with respect to their ownership and disposition of our Class A Ordinary Shares and the significant penalties for non-compliance.

Information Reporting and Backup Withholding

Dividend payments with respect to our Class A Ordinary Shares and proceeds from the sale or exchange of our Class A Ordinary Shares may be subject to information reporting to the IRS and possible U.S. backup withholding. Backup withholding will not apply, however, to a U.S. Holder who furnishes a correct taxpayer identification number and makes other required certifications, or who is otherwise exempt from backup withholding and establishes such exempt status.

Backup withholding is not an additional tax. Amounts withheld as backup withholding may be credited against a U.S. Holder’s U.S. federal income tax liability, and a U.S. Holder generally may obtain a refund of any excess amounts withheld under the backup withholding rules by timely filing the appropriate claim for refund with the IRS and furnishing any required information.

MATERIAL CAYMAN ISLANDS TAX CONSIDERATIONS

Prospective investors should consult their professional advisors on the possible tax consequences of buying, holding or selling any of our Class A Ordinary Shares under the laws of their country of citizenship, residence or domicile.

Cayman Islands Taxation

The following is a discussion on certain Cayman Islands income tax consequences of an investment in shares of a Cayman Islands company. The discussion is a general summary of present law, which is subject to prospective and retroactive change. It is not intended as tax advice, does not consider any investor’s particular circumstances, and does not consider tax consequences other than those arising under Cayman Islands law. On this basis, the following discussion is the opinion of Conyers Dill & Pearman LLP, Cayman Islands counsel.

Under Existing Cayman Islands Laws

Payments of dividends and capital in respect of shares will not be subject to taxation in the Cayman Islands and no withholding will be required on the payment of interest and principal or a dividend or capital to any holder of shares, as the case may be, nor will gains derived from the disposal of the Class A Ordinary Shares be subject to Cayman Islands income or corporation tax. The Cayman Islands currently has no income, corporation or capital gains tax and no estate duty, inheritance tax or gift tax.

No stamp duty is payable in respect to the issue of shares or on an instrument of transfer in respect of a share. However, an instrument of transfer in respect of our securities, including our warrants, is stampable if executed in or brought into the Cayman Islands.

Apollomics has been incorporated under the laws of the Cayman Islands as an exempted company with limited liability and, as such, has applied for and obtained an undertaking dated October 4, 2022 from the Financial Secretary of the Cayman Islands in the following form:

The Tax Concessions Law

Undertaking as to Tax Concessions

In accordance with the Tax Concessions Law the following undertaking is hereby given to Apollomics Inc. (the “Company”).

These concessions shall be for a period of twenty years from the date of the undertaking.

ENFORCEABILITY OF CIVIL LIABILITIES UNDER U.S. SECURITIES LAWS

We are a holding company incorporated in the Cayman Islands with its headquarters in the United States. We conduct our operations through Apollomics US, our headquarters based in California, U.S., as well as Crownmab, our wholly-owned subsidiary in the PRC.

Apollomics US, a California corporation and our wholly-owned subsidiary, serves as our agent to receive service of process in any action against us in any U.S. federal or state court arising out of the transactions described in this prospectus. The address of Apollomics U.S. is 989 East Hillsdale Blvd., Ste 220, Foster City, CA 94404 USA.

We have been advised by its Cayman Islands legal counsel that the courts of the Cayman Islands are unlikely (i) to recognize or enforce judgments of courts of the United States predicated upon the civil liability provisions of the federal securities laws of the United States or any state; and (ii) in original actions brought in the Cayman Islands, to impose liabilities predicated upon the civil liability provisions of the federal securities laws of the United States or any state, so far as the liabilities imposed by those provisions are penal in nature. Although there is no statutory enforcement in the Cayman Islands of judgments obtained in the United States, the courts of the Cayman Islands will recognize and enforce a foreign money judgment of a foreign court of competent jurisdiction without retrial on the merits based on the principle that a judgment of a competent foreign court imposes upon the judgment debtor an obligation to pay the sum for which judgment has been given provided certain conditions are met. For a foreign judgment to be enforced in the Cayman Islands, such judgment must be final and conclusive and for a liquidated sum, and must not be in respect of taxes or a fine or penalty, inconsistent with a Cayman Islands judgment in respect of the same matter, impeachable on the grounds of fraud or obtained in a manner, and or be of a kind the enforcement of which is contrary to natural justice or the public policy of the Cayman Islands.

In addition, we have been advised by its PRC legal counsel, JunHe LLP, according to its interpretation of the currently in-effect PRC laws and regulations, that the recognition and enforcement of foreign judgments are basically provided for under the PRC Civil Procedures Law. PRC courts may recognize and enforce foreign judgments in accordance with the requirements, public policy considerations and conditions set forth in applicable provisions of PRC laws relating to the enforcement of civil liability, including the PRC Civil Procedures Law, based either on treaties between the PRC and the country where the judgment is made or on principles of reciprocity between jurisdictions. China does not have any treaties or other form of reciprocity with the United States or the Cayman Islands that provide for the reciprocal recognition and enforcement of foreign judgments. In addition, according to the PRC Civil Procedures Law, a PRC court will not enforce a foreign judgment against us or our directors and officers if they decide that the judgment violates the basic principles of PRC law or national sovereignty, security or public interest. As a result, it is uncertain whether and on what basis a PRC court would enforce a judgment rendered by a court in the U.S. based upon the civil liability provisions of the U.S. federal securities laws. Further, pursuant to the Civil Procedures Law of the PRC, any matter, including matters arising under U.S. federal securities laws, in relation to assets or personal relationships may be brought as an original action in mainland China only if the institution of such action satisfies the conditions specified in the Civil Procedures Law of the PRC. As a result of the conditions set forth in the Civil Procedures Law and the discretion that PRC courts have in determining whether the conditions are satisfied and whether to accept the action for adjudication, there remains uncertainty as to whether an investor will be able to bring an original action in a PRC court based on U.S. federal securities laws.

In addition, we have been advised by our PRC legal counsel, JunHe LLP, according to its interpretation of the currently in-effect PRC laws and regulations, that it is uncertain (i) whether and on what basis a PRC court would enforce judgment rendered by a court in the U.S. based upon the civil liability provisions of U.S. federal securities laws; and (ii) whether an investor will be able to bring an original action in a PRC court based on U.S. federal securities laws. As such, you may not be able to or may experience difficulties or incur additional costs in order to enforce judgments obtained in U.S. courts based upon the civil liability provisions of U.S. federal

31

securities laws in mainland China or bring original actions in mainland China based on U.S. federal securities laws. Similarly, service of process upon Hong Kong-based entities or individuals may be difficult to obtain within the United States. There is also uncertainty as to whether the courts of Hong Kong would (i) recognize or enforce judgments of U.S. courts obtained against these Hong Kong-based entities or individuals predicated upon the civil liability provisions of the securities laws of the United States or any state in the United States or (ii) entertain original actions brought in Hong Kong against these Hong Kong-based entities or individuals predicated upon the securities laws of the United States or any state in the United States. A judgment of a court in the United States predicated upon U.S. federal or state securities laws may be enforced in Hong Kong at common law by bringing an action in a Hong Kong court on that judgment for the amount due thereunder and then seeking summary judgment on the strength of the foreign judgment, provided that the foreign judgment, among other things, is (1) for a debt or a definite sum of money (not being taxes or similar charges to a foreign government taxing authority or a fine or other penalty) and (2) final and conclusive on the merits of the claim, but not otherwise. Such a judgment may not, in any event, be so enforced in Hong Kong if (a) it was obtained by fraud, (b) the proceedings in which the judgment was obtained were opposed to natural justice, (c) its enforcement or recognition would be contrary to the public policy of Hong Kong, (d) the court of the United States was not jurisdictionally competent, or (e) the judgment was in conflict with a prior Hong Kong judgment. Hong Kong has no arrangement for the reciprocal enforcement of judgments with the United States. As a result, there is uncertainty as to the enforceability in Hong Kong, in original actions or in actions for enforcement, of judgments of United States courts of civil liabilities predicated solely upon the federal securities laws of the United States or the securities laws of any state or territory within the United States.
