INFORMATION CONTAINED IN THIS REPORT ON FORM 6-K/A

On October 28, 2021, Immatics N.V. (the “Company”) issued an amended interim report for the three-month period ended March 31, 2021, which is attached hereto as Exhibit 99.1.

INCORPORATION BY REFERENCE

This Report on Form 6-K, including Exhibit 99.1 hereto, shall be deemed to be incorporated by reference into the registration statements on Form F-3 (Registration Nos. 333 258351 and 333-240260) of Immatics N.V. and to be a part thereof from the date on which this report is filed, to the extent not superseded by documents or reports subsequently filed or furnished.

EXPLANATORY NOTE

This Amendment No.1 to Form 6-K (this “Amendment” or “Form 6-K/A”) amends the Immatics N.V. (“Immatics” or the “Company”) interim report for the three-month periods ended March 31, 2021 on Form 6-K originally filed with Securities and Exchange Commission (“SEC”) on May 18, 2021 (the “Original Filing”). This Amendment restates the Company’s previously issued unaudited condensed consolidated financial statements as of and for the three-month period ended March 31, 2021.

On April 12, 2021, the Acting Director of the Division of Corporation Finance and Acting Chief Accountant of the Securities and Exchange Commission (the “SEC”) together issued a statement regarding the accounting and reporting considerations for warrants issued by special purpose acquisition companies entitled “Staff Statement on Accounting and Reporting Considerations for Warrants Issued by Special Purpose Acquisition Companies (“SPACs”)” (the “SEC Statement”). The Staff Statement clarified guidance for all SPAC-related companies regarding the accounting and reporting for their warrants that could result in the warrants issued by SPACs being classified as a liability measured at fair value, with non-cash fair value adjustments recorded in the statement of operations for each reporting period. This guidance was applicable for companies that reported using U.S. GAAP.

Under IFRS, there are alternative perspectives on whether warrants issued by a SPAC that are considered in determining the IFRS 2 charge for listing services can (i) continue to be accounted for under IFRS 2 and presented in equity or (ii) should be evaluated under IAS 32 and presented as a liability and adjusted to fair value at the balance sheet date.

Given the alternative perspectives, Immatics believed there was a choice to account for the warrants under IFRS 2 as part of equity or as a liability under IAS 32 and elected to present the warrants as part of equity. However, Immatics has observed that another foreign private issuer has restated its financial statements recently following the dialogue it reported with the Staff, and changed the presentation of its warrants from equity to liability under IFRS.

Immatics previously classified its warrants as equity. The Company reviewed and discussed the accounting treatment of its warrants with its advisors and the audit committee of its board of directors and evaluated the applicability and potential impact of the SEC Staff’s view on the accounting for the warrants under IFRS.

Following this review and evaluation, and after consulting with management, the Company’s board of directors, upon the recommendation of the audit committee, concluded that, in light of the recent developments, it should restate its financial statements to correct for the misapplication of IFRS and to account for the warrants as a liability that is adjusted to fair value. Therefore the Company’s unaudited condensed consolidated financial statements for the interim report for the three-month period ended March 31, 2021 (the “Affected Period”) should no longer be relied upon and should be restated to present the warrants as a liability and to adjust for the changes in fair value. Further, any previously furnished or filed reports, earnings releases, guidance, investor presentations or similar communications regarding the restatement information for the Affected Period should also no longer be relied upon. This restatement results in non-cash, non-operating financial statement corrections for the Affected Period and has no impact on the Company’s cash position, operating expenses or cash flows or its ongoing operations or future plans.

As all material restatement information will be included in this Amendment, investors and others should rely only on the financial information and other disclosures regarding the restatement information for the Affected Period in this Amendment and in future filings with the SEC (as applicable) and should not rely on any previously furnished or filed reports, earnings releases, guidance, investor presentations or similar communications regarding restatement information for the Affected Period.

This Amendment speaks as of the filing date of the Original 6-K Filing and does not reflect events occurring after the filing date of the Original Filing.

Notes to the Unaudited Condensed Consolidated Financial Statements of Immatics N.V.

1. Group information

Immatics N.V, together with its German subsidiary Immatics Biotechnologies GmbH and its U.S. subsidiary, Immatics US Inc., (“Immatics” or “the Group”) is a biotechnology group that is primarily engaged in the research and development of T cell redirecting immunotherapies for the treatment of cancer. Immatics N.V., a Dutch public limited liability company, was converted on July 1, 2020 from Immatics B.V., a Dutch company with limited liability. Immatics Biotechnologies GmbH and Immatics US Inc. became subsidiaries of Immatics N.V. as part of the ARYA Merger on July 1, 2020. Immatics N.V is registered with the commercial register at the Netherlands Chamber of Commerce under RSIN 861058926 with a corporate seat in Amsterdam and is located at Paul-Ehrlich Str. 15 in 72076 Tübingen, Germany. Prior to July 1, 2020, Immatics N.V. was a shell company with no active trade or business or subsidiaries and all relevant assets and liabilities as well as income and expenses were borne by Immatics Biotechnologies GmbH and its U.S. subsidiary Immatics US, Inc. Therefore, the comparable financial results for the three months ended March 31, 2020 represent consolidated financial results of Immatics Biotechnologies GmbH

These interim condensed consolidated financial statements of the Group for the three months ended March 31, 2021 were authorized for issue by the Management Board of Immatics N.V. on May 18, 2021 except for the impact of the matter discussed in Note 3.2 Restatement of Unaudited Condensed Consolidated Financial Statements to correct the presentation of the warrants which was approved by the Audit Committee of Immatics N.V. on October 26, 2021.

2. Significant events and changes in the current reporting period

The Group was affected by the following events or transactions during the three months ended March 31, 2021.

COVID-19

In December 2019, a novel strain of coronavirus (“COVID-19”) emerged in Wuhan, China. While initially concentrated in China, spread of the outbreak is now worldwide. On January 30, 2020, the World Health Organization declared the outbreak a pandemic and a global emergency. In response, many countries and businesses still institute travel restrictions, quarantines, and office closures. The extent of the pandemic and governmental responses may impact our ability to obtain raw materials and equipment used for research and development, obtain sufficient additional funds to finance our operations, and conduct clinical trials, any of which could materially and adversely affect our business.

Management continues to monitor the situation and enacted significant measures to protect the Group’s supply chain, employees, and the execution of clinical trials. To date, the pandemic has resulted in a slowdown in activities related to the Group’s laboratory operations and at some of its suppliers. The ongoing spread of COVID-19 may also negatively impact the Group’s ability to conduct clinical trials, including potential delays and restrictions on the Group’s ability to recruit and retain patients, and the availability of principal investigators and healthcare employees. COVID-19 could also affect the operations of contract research organizations, which may also result in delays or disruptions in the supply of product candidates. Immatics continues to expand its clinical programs with additional clinical trial sites opening in the U.S. and in Europe. Given the ongoing vaccination programs both in the U.S. and in Europe we currently do not expect significant negative impacts on the Group’s activities in the future.

3. Significant accounting policies

3.1 Basis of presentation

The interim condensed consolidated financial statements of the Group as of March 31, 2021 and for the three months ended March 31, 2021 and 2020 have been prepared in accordance with International Accounting Standard 34 (“Interim Financial Reporting”), as issued by the International Accounting Standards Board (“IASB”).

The interim condensed consolidated financial statements do not include all the information and disclosures required in the annual financial statements and should be read in conjunction with the Group’s annual financial statements for the year ended December 31, 2020, which have been prepared in accordance with International Financial Reporting Standards (“IFRS”) as issued by the IASB, taking into account the recommendations of the International Financial Reporting Standards Interpretations Committee (“IFRS IC”).

The interim condensed consolidated financial statements are presented in Euros. Amounts are stated in thousands of Euros, unless otherwise indicated.

The accounting policies adopted in the preparation of the interim condensed consolidated financial statements are consistent with those followed in the preparation of the Group’s annual consolidated financial statements for the year ended December 31, 2020. The new and amended standards and interpretations applied for the first time as of January 1, 2021, as disclosed in the notes to the consolidated financial statements for the year ended December 31, 2020, had no impact on the interim condensed consolidated financial statements of the Group for the three months ended as of March 31, 2021.

10

The Group had a non-controlling interest, representing approximately 3.96% of the Group’s Immatics US, Inc. subsidiary as of March 31, 2020 held by MD Anderson. On July 1, 2020 and as part of the ARYA Merger, this non-controlling interest in Immatics US, Inc. was exchanged for ordinary shares in Immatics N.V.

3.2 Restatement of Unaudited Condensed Consolidated Financial Statements to correct the presentation of the warrants

On April 12, 2021, the Acting Director of the Division of Corporation Finance and Acting Chief Accountant of the Securities and Exchange Commission (the “SEC”) together issued a statement regarding the accounting and reporting considerations for warrants issued by special purpose acquisition companies entitled “Staff Statement on Accounting and Reporting Considerations for Warrants Issued by Special Purpose Acquisition Companies (“SPACs”)” (the “SEC Statement”). The Staff Statement clarified guidance for all SPAC-related companies regarding the accounting and reporting for their warrants that could result in the warrants issued by SPACs being classified as a liability measured at fair value, with non-cash fair value adjustments recorded in the statement of operations for each reporting period. This guidance was applicable for companies that reported using U.S. GAAP.

Under IFRS, there are alternative perspectives on whether warrants issued by a SPAC that are considered in determining the IFRS 2 charge for listing services can (i) continue to be accounted for under IFRS 2 and presented in equity or (ii) should be evaluated under IAS 32 and presented as a liability and adjusted to fair value at the balance sheet date.

Given the alternative perspectives, Immatics believed there was a choice to account for the warrants under IFRS 2 as part of equity or as a liability under IAS 32 and elected to present the warrants as part of equity. However, Immatics has observed that another foreign private issuer has restated its financial statements recently following the dialogue it reported with the Staff, and changed the presentation of its warrants from equity to liability under IFRS.

Immatics previously classified its warrants as equity.. The Company reviewed and discussed the accounting treatment of its warrants with its financial advisors and the audit committee of its board of directors and evaluated the applicability and potential impact of the SEC Staff’s view on the accounting for the warrants under IFRS.

Following this review and evaluation, and after consulting with management, the Company’s board of directors, upon the recommendation of the audit committee, concluded that, in light of the recent developments it should restate its financial statements to correct for the misapplication of IFRS and to account for the warrants as a liability that is adjusted to fair value

The financial statements of 2020 were restated in the Amendment No. 1 of the 20-F published on October 28, 2021.

The Chief Executive Officer is the chief operating decision maker who regularly reviews the consolidated operating results and makes decisions about the allocation of the Group’s resources.

5. Other current assets

The Group recognizes receivables for government grants, when it is reasonably assured that the grant will be received, and all contractual conditions have been complied with. As of March 31, 2021, and December 31, 2020, no receivables were considered impaired.

Prepaid expenses include prepaid insurance expenses of €0.6 million as of March 31, 2021 and €1.0 million as of December 31, 2020. The Group paid €0.5 million as of March 31, 2021 and €0.5 million as of December 31, 2020 of incremental cost for the successful arrangement of the Celgene Switzerland LLC (“BMS”) and Genmab A/S (“Genmab”) collaboration agreements.

Other assets include receivables from capital gains tax of €0.5 million as of March 31, 2021 and €0.4 million as of December 31, 2020. The remaining amount is related to deposits.

13

6. Revenue from collaboration agreements

The Group earns revenue through strategic collaboration agreements with third party pharmaceutical and biotechnology companies. As of March 31, 2021, the Group had four strategic collaboration agreements in place. All collaboration agreements are still at pre-clinical stage. During the three months ended March 31, 2021, the Group did not enter into any new collaboration agreements.

The Group earned revenue from collaboration agreements from the following collaborators during the three months ended March 31, 2021 and 2020:

As of March 31, 2021, the Group has not recognized any royalty or milestone revenue under the collaboration agreements, due to the scientific uncertainty of achieving the milestones or the successful commercialization of a product. As of March 31, 2021, Immatics had not received any milestone or royalty payments in connection with the collaboration agreements. The Group plans to recognize the remaining deferred revenue balance into revenue as it performs the related performance obligations under each contract. Deferred revenue related to the collaboration agreements consists of the following as of March 31, 2021 and December 31, 2020:

The Group recognized expenses related to the amortization of capitalized cost of obtaining a contract of €0.1 million and €0.1 million for the three months ended March 31, 2021 and March 31, 2020.

14

7. Financial result

Financial income and financial expenses consist of the following:

Foreign currency gains mainly consist of unrealized gains in connection with our USD holdings.

The fair value of the warrants increased from €2.35 per warrant as of December 31, 2020 to €2.52 as of March 31, 2021. The result is a increase in fair value of warrant liabilities of €1.2 million for the three months ended March 31, 2021.

Losses on other financial instruments consist of losses from unrealized currency forward contracts.

8. Income Tax

During the three months ended March 31, 2021 and 2020, the Group generated losses in both Germany and the U.S. During the three months ended March 31, 2021 and 2020, the Group’s German operations were subject to a statutory tax rate of 29.1%. In the U.S., the Group was subject to a corporate income tax rate of 21% during the three months ended March 31, 2021 and 2020.

As of March 31, 2021, and December 31, 2020, no deferred tax assets have been recognized in respect of these losses, due to the uncertainty of the Group’s ability to generate taxable profits in the foreseeable future. The current assessment regarding the usability of deferred tax assets may change, depending on the Group’s taxable income in future years, which could result in the recognition of deferred tax assets This may result in higher or lower deferred tax assets related to tax losses carried forward.

Due to the ARYA Merger described in Note 3 of the Group’s annual financial statements for the year ended December 31, 2020, there are certain limitations on tax losses carried forward for net operating losses incurred by Immatics US, Inc., under Section 382 of the U.S. Internal Revenue Code.

9. Property, plant and equipment and Right-of-use assets

During the three months ended March 31, 2021 and March 31, 2020, the Group acquired property, plant and equipment in the amount of €0.6 million and €1.7 million, respectively.

During the three months ended March 31, 2021, new leases and extensions to existing lease agreements resulted in an increase in right-of-use assets and corresponding lease liability in the amount of €0.5 million, mainly due to the commencement of a lease agreement of an additional office floor in Tübingen, Germany and an extended facility contract in München, Germany. The future lease payments for these lease contracts are approximately €0.1 million for the remainder of year 2021, €0.4 million within one to five years and € 0.1 million fiscal years after 2025.The Group used its incremental borrowing rate (“IBR”) to calculate the initial lease liability.

15

10. Provisions

Provisions consisted of the following as of March 31, 2021 and December 31, 2020:

These amounts include provisions for the Group’s annual employee bonuses, which are due to be paid each December. These amounts are classified as a provision as of March 31, 2021, because the amount to be paid is uncertain.

11. Other current liabilities

Other current liabilities consisted of the following as of March 31, 2021 and December 31, 2020.

12. Share-based payments

Immatics Biotechnologies GmbH previously issued share-based awards to employees under two different plans. Under the Immatics Biotechnologies GmbH Stock Appreciation Program 2010 (the “2010 Plan”), the Company issued stock appreciation rights (“SARs”), which the Group accounted for as cash-settled awards. Under the Immatics Biotechnologies 2016 Equity Incentive Plan (“2016 Plan”), the Company issued tandem awards, which contained the possibility to function as either a SAR or a stock option.

The Group accounted for awards issued under the 2016 Plan, which were redeemable in either cash or equity shares at the Group’s discretion, as equity settled.

For the three months ended March 31, 2020, Immatics recognized €0.7 million expenses in connection with the 2010 and 2016 Plan, of which €0.66 million and €0.04 million relate to cash and equity settled awards, respectively.

Prior to the ARYA Merger, Immatics N.V. established the new equity incentive plan (“2020 Equity Plan”). As part of the ARYA Merger, all outstanding awards under the 2010 Plan and 2016 Plan were replaced by a combination of cash payments and share-based awards under the 2020 Equity Plan in Immatics N.V. Under the 2020 Plan, management and employees have been granted different types of options.

As part of the replacement, active employees and management members received stock options (“Matching Stock Options”) to acquire shares in Immatics N.V. The Matching Stock Options have an exercise price of $10.00 and vest in full on July 31, 2021. The award recipient must remain employed by Immatics or one of its affiliates through the vesting date, to receive the option. The awards have a ten-year contract life.

16

Matching Stock Options outstanding as of March 31, 2021:

For any outstanding 2016 Plan and 2010 Plan awards scheduled to vest on or after January 1, 2021, employees received replacement stock options (“Converted Options”) to acquire shares in Immatics N.V. The Converted Options have comparable terms as previous awards, with revised exercise prices reflecting the reorganized capital structure of Immatics. The options granted under the 2020 Equity Plan that gives employees the right to acquire shares in Immatics N.V., are accounted for as a modification under IFRS 2, with the incremental fair value expensed over the remaining vesting period.

The incremental fair value is the difference between the fair value of the options to purchase ordinary shares under the 2020 Equity Plan to acquire shares in Immatics N.V., and the fair value of the exchanged unvested SAR (both measured at the date on which the replacement award is issued).

Based on the terms of the Converted Options award agreements, the awards had a service commencement date in June 2020. However, the grant date criteria for these awards, as specified in IFRS 2 and the underlying award agreements, were not met until July 1, 2020.

Converted Options outstanding as of March 31, 2021:

17

Under the 2020 Plan, Immatics also issues employee stock options with a service requirement (“Service Options”), to acquire shares of Immatics N.V. The service-based options will vest solely on a four-year time-based vesting schedule. These Service Options are granted on a recurring basis.

The Company granted Service Options on March 30, 2021 which were accounted for using a fair value of $8.42. Immatics applied a Black Scholes pricing model to estimate the fair value of the Service Options.

Service Options outstanding as of March 31, 2021:

In addition, after the closing of the ARYA Merger certain executive officers and key personnel of the Group received under the 2020 Equity Plan performance-based options (“PSUs”), vesting based on both the achievement of market capitalization milestones and satisfaction of a four-year time-based vesting schedule. The PSUs are split into three equal tranches. The performance criteria for each of the three respective tranches requires Immatics to achieve a market capitalization of at least $1.5 billion, $2 billion and $3 billion, respectively.

A Monte-Carlo simulation model has been used to measure the fair value at grant date of the PSUs. This model incorporates the impact of the performance criteria regarding market capitalization described above in the calculation of the award’s fair value at grant date.

There were no PSUs granted during the three months ended March 31, 2021.

PSUs outstanding as of March 31, 2021:

18

The Group recognized total employee-related share-based compensation expense, during the three months ended March 31, 2021 and 2020 as set out below:

The increase in share-based compensation expense is attributable to replacement awards issued under the 2020 Equity Plan for the outstanding awards under the 2010 Plan and 2016 Plan and the new awards issued under the 2020 Equity Plan, as described above.

13. Related party disclosures

During the three months ended March 31, 2021 the Group did not enter into any new related-party transactions with its key management personnel or with related entities.

14. Financial Instruments

Set out below are the carrying amounts and fair values of the Group’s financial instruments that are carried in the interim condensed consolidated financial statements.

19

The carrying value of financial instruments, such as cash and cash equivalents, deposits, accounts receivable and accounts payable approximate their fair value based on the short-term maturities of these instruments. The fair values of the financial assets and liabilities are included at the amount at which the instrument could be exchanged in a current transaction between willing parties, other than in a forced or liquidation sale.

The following methods and assumptions were used to estimate the fair values: All financial assets, except for derivatives, which are categorized Level 2, are categorized Level 1 and therefore are valued using quoted (unadjusted) market prices. All financial liabilities are also categorized Level 1.

The Company accounted for the warrants issued to investors with a cashless exercise mechanism as a current financial liability according to provisions of IAS 32. The Company measured the warrants at fair value by using the closing price of warrants at NASDAQ. The warrants were measured in each reporting period. Changes in the fair value were recognized in the Company’s consolidated statement of loss as financial income or expense, as appropriate. The warrants were classified as level 1.

15. Events occurring after the reporting period

The Company evaluated subsequent events for recognition or disclosure through May 18, 2021 and did not identify material subsequent events.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND

RESULTS OF OPERATIONS

The following discussion and analysis is based on the financial information of Immatics N.V, together with its German subsidiary Immatics Biotechnologies GmbH and its U.S. subsidiary, Immatics US, Inc. (“Immatics”, the “Company”, the “Group”, “we”, “our”).You should read the following discussion and analysis of our financial condition and results of operations together with our unaudited interim condensed consolidated financial statements for the three months period ended March 31, 2021 and 2020 included in this interim report. You should also read our operating and financial review and prospect and our Consolidated Financial Statements for fiscal year 2020, and the notes thereto, in our Annual Report on Form 20-F filed with the SEC on March 30, 2021 as well as the Amendment No. 1 to the form 20-F for the year ended December 31, 2020 filed with the SEC on October 28, 2021. The following discussion is based on the financial information of Immatics prepared in accordance with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board, which may differ in material respects from generally accepted accounting principles in other jurisdictions, including U.S. generally accepted accounting principles.

Overview

We are a clinical-stage biotechnology company dedicated to the development of T cell receptor (“TCR”)-based immunotherapies for the treatment of cancer. Our focus is the generation of novel therapeutic options for solid tumor patients. Solid tumors constitute the majority of all cancers, and relapsed and/or refractory solid tumor patients have an unmet medical need. We believe that by identifying true cancer targets and the right TCRs, we will be well positioned to transform current solid tumor treatment paradigms by delivering cellular and bispecific product candidates that have the potential to improve the lives of cancer patients.

One of the challenges of effectively treating solid tumors is the lack of cancer-specific targets. By utilizing TCR-based therapeutics, we are capable of directing T cells not only to targets on the surface of the cancer cell, but also to intracellular cancer targets that are not accessible through classical antibody-based or CAR-T therapies. We have developed a suite of proprietary technologies to identify what we refer to as “true targets” and “right TCRs.” True targets are (i) naturally occurring at significant levels on native tumor tissue, and (ii) highly specific to cancer cells. Right TCRs are (i) high-affinity TCRs, and (ii) highly specific to the respective cancer target, with no or minimized cross-reactivities to healthy tissues.

We believe that the elucidation of these targets provides us the opportunity to develop a pipeline of novel TCR-based product candidates that generate a meaningful therapeutic impact on the lives of cancer patients by going beyond an incremental clinical benefit. We are developing our targeted immunotherapy product candidates through two distinct treatment modalities: Adoptive Cell Therapies (“ACT”) and antibody-like Bispecifics. Each is designed with distinct attributes to produce the desired therapeutic effect for patients at different disease stages and with different types of tumors. Our current proprietary pipeline comprises seven therapeutic programs, three of which are being evaluated in clinical trials. In addition, we are collaborating with world-leading partners, including Amgen Inc. (“Amgen”), Genmab A/S (“Genmab”), Bristol-Myers Squibb (“BMS”) and GlaxoSmithKline plc (“GSK”), to develop ten additional therapeutic programs covering ACT and Bispecifics.

Since our inception, we have focused on developing our technologies and executing our preclinical and clinical research programs with the aim to deliver the power of T cells to cancer patients. We do not have any products approved for sale. We have funded our operations primarily through equity financing and, to a lesser extent, through upfront payments from our collaborators.

We have assembled a team of approximately 285 employees.

We have raised approximately €590 million in total through licensing payments from our collaborators and through private and public placements of securities including the proceeds from the ARYA Merger and the PIPE Financing that closed on July 1, 2020. We are holding Cash and cash equivalents as well as other financial assets of €216.7 million as of March 31, 2021. These will be used for general corporate purposes and provide a cash reach into 2023.

21

Since our inception, we have incurred net losses, which have been significant in recent periods. We expect to continue to incur significant expenses and increasing net losses for the foreseeable future as we continue our research and development efforts and seek to obtain regulatory approval for and commercialize our product candidates. Our future profitability will be dependent upon the successful development, approval and commercialization of our product candidates and achieving a level of revenues adequate to support our cost structure. We may never achieve profitability and, unless and until we do, we will continue to need to raise additional capital. Our net losses may fluctuate significantly from period to period and year to year.

Recent Developments

Business Impact of the COVID-19 Pandemic

Our operations, similar to those of other life sciences companies, have been impacted by the COVID-19 pandemic. The extent of the pandemic and governmental responses may impact our ability to obtain raw materials and equipment used for research and development, obtain sufficient additional funds to finance our operations, and conduct clinical trials, any of which could materially and adversely affect our business.

Management continues to monitor the situation and enacted significant measures to protect the Group’s supply chain, employees, and the execution of clinical trials. To date, the pandemic has resulted in a slowdown in activities related to the Group’s laboratory operations and at some of its suppliers. The ongoing spread of COVID-19 may also negatively impact the Group’s ability to conduct clinical trials, including potential delays and restrictions on the Group’s ability to recruit and retain patients, and the availability of principal investigators and healthcare employees. COVID-19 could also affect the operations of contract research organizations, which may also result in delays or disruptions in the supply of product candidates. Immatics continues to expand its clinical programs with additional clinical trial sites opening in the U.S. and in Europe. Given the ongoing vaccination program both in the U.S. and in Europe we currently do not expect significant negative impacts on the Group’s activities in the future.

Data Update on Dose Escalation from Ongoing ACTengine^® Cell Therapy Programs

On March 17, 2021, we announced clinical data update from the dose escalation cohorts of our ongoing Phase 1 trials of the engineered Adoptive Cell Therapy approach (also known as TCR-T). The treatment of patients with ACTengine^® product candidates IMA201, IMA202 and IMA203 at initial dose levels below one billion transduced cells, intended to establish safety and first biological activity, showed first anti-tumor activity with 9 out of 10 evaluable patients showing disease control as well as tumor shrinkage observed in 8 out of 10 patients including one partial response. Clinical observations were consistent with observed robust engraftment, persistence and tumor infiltration of infused ACTengine^® T cells. Overall, all product candidates demonstrated a manageable tolerability profile.

Components of Operating Results

Revenue from Collaboration Agreements

To date, we have not generated any revenue from the sale of pharmaceutical products. Our revenue has been solely derived from our collaboration agreements with Amgen, Genmab, BMS and GSK.

Our revenue from collaboration agreements consists of upfront payments as well as reimbursement of research and development expenses. Upfront payments are initially recorded on our statement of financial position as deferred revenue and are subsequently recognized as revenue on a cost-to-cost measurement basis, in accordance with our accounting policy as described further under “—Critical Accounting Policies and Significant Judgments and Estimates.”

22

As part of the collaboration arrangements, we grant exclusive licensing rights for the development and commercialization of future product candidates, developed for specified targets defined in the respective collaboration agreement. We carry out our research activities using our proprietary technology and know-how, participate in joint steering committees, and prepare data packages. In each of our collaboration agreements, these commitments represent one combined performance obligation, because the research activities are mutually dependent and the collaborator is unable to derive significant benefit from our access to these targets without our research activities, which are highly specialized and cannot be performed by other organizations.

The collaboration agreements resulted in €186.6 million of upfront cash payments, intended to fund the research and development activities under each contract. As part of the agreements, we contribute our XPRESIDENT and other technologies, as well as commit to participating in joint research activities. In addition, we agree to license certain target rights and the potential product candidates developed under the collaboration.

Under each of our collaboration agreements, we are entitled to receive payments for certain development and commercial milestone events, in addition to royalty payments upon successful commercialization of a product. The uncertainty of achieving these milestones significantly impacts on our ability to generate revenue.

Our ability to generate revenue from sales of pharmaceutical products and to become profitable depends on the successful commercialization of product candidates by us or by our collaboration partners. In the foreseeable future, we do not expect revenue from product sales. To the extent that existing or potential future collaborations generate revenue, our revenue may vary due to many uncertainties in the development of our product candidates and other factors.

Research and Development Expenses

Research and development expenses consist primarily of personnel-related costs (including share-based compensation) for the various research and development departments, intellectual property (“IP”) expenses, facility-related costs and amortization as well as direct expenses for clinical and preclinical programs.

Our core business is focused on the following initiatives with the goal of providing novel immuno-oncology therapies to cancer patients:

Research expenses are defined as costs incurred for current or planned investigations undertaken with the prospect of gaining new scientific or technical knowledge and understanding. All research and development costs are expensed as incurred due to scientific uncertainty.

We expect our research and development expenses to increase substantially in the future as we advance existing and future proprietary product candidates into and through clinical studies and pursue regulatory approval. The process of conducting the necessary clinical studies to obtain regulatory approval is costly and time-consuming. We are increasing our headcount to support our continued research activities and development of our product candidates. Clinical studies generally become larger and more costly to conduct as they advance into later stages and, in the future, we will be required to make estimates for expense accruals related to clinical study expenses. At this time, we cannot reasonably estimate or know the nature, timing and estimated costs of the efforts that will be necessary to complete the development of any product candidates that we develop from our programs. Our research and development programs are at an early stage. We must demonstrate our products’ safety and efficacy in humans through extensive clinical testing. We may experience numerous unforeseen events during, or as a result of, the testing process that could delay or prevent commercialization of our products, including but not limited to the following:

23

Clinical testing is very expensive, can take many years, and the outcome is uncertain. It could take several years before we learn the results from any clinical trial using ACT or TCR Bispecifics. The data collected from our clinical trials may not be sufficient to support approval by the FDA, the EMA or comparable regulatory authorities of our ACT- or TCR Bispecifics-based product candidates for the treatment of solid tumors. The clinical trials for our products under development may not be completed on schedule and the FDA, EMA or regulatory authorities in other countries may not ultimately approve any of our product candidates for commercial sale. If we fail to adequately demonstrate the safety and effectiveness of any product candidate under development, we may not receive regulatory approval for those product candidates, which would prevent us from generating revenues or achieving profitability.

General and Administrative Expenses

General and administrative expenses consist primarily of personnel-related costs (including share-based compensation) for finance, legal, human resources, business development and other administrative and operational functions, professional fees, accounting and legal services, information technology and facility-related costs. These costs relate to the operation of the business, unrelated to the research and development function or any individual program.

Due to our planned substantial increase in research and development expenses, as explained above, we also expect that our general and administrative expenses will increase significantly. We expect to incur increased accounting, audit, legal, regulatory, compliance, director and officer insurance costs as well as investor and public relations expenses associated with being a public company. Additionally, if and when a regulatory approval of a product candidate appears likely, we anticipate an increase in payroll and expenses as a result of our preparation for commercial operations.

Other Income

We receive income through government grants for specific research and development projects. We recognize grant income as we perform research and development activities, specified by the grant agreements.

Other components of other income have historically been immaterial.

Financial Result

Financial result consists of both financial income and financial expense. Financial income results primarily from interest income on cash and foreign exchange gains. Our financial expense consists of interest expense related to lease liabilities and foreign exchange. Additionally, our warrants are classified as Other Financial Liabilities. The change in fair value of warrant liabilities consists of the change in fair value of these public warrants.

Results of Operations

Comparison of the Three Months Ended March 31, 2021 and March 31, 2020

The following table summarizes our consolidated statements of operations for each period presented:

24

Revenue from Collaboration Agreements

The following table summarizes our collaboration revenue for the periods indicated:

Our Revenue from collaboration agreements increased from €7.0 million for the three months ended March 31, 2020 to €7.4 million for the three months ended March 31, 2021. The increase resulted from the collaboration agreement with GSK consummated in December 2019 and was therefore in the ramp-up phase, which resulted in additional revenue of €1.2 million, as well as an increase in revenue of €0.9 million from the collaboration with BMS, as compared to the three months ended March 31, 2020.

The increase in revenue is partly offset by the revenue recognized under the Amgen agreement. As we recognize revenue for collaboration agreements on a cost-to-cost model based on research activities, we recognized €1.9 million less revenue under the Amgen agreement compared to the three months ended March 31, 2020. This decrease is due to the fact that the currently ongoing working packages within the Amgen collaboration are performed directly by Amgen and we therefore did not incur significant cost under the agreement for the three months ended March 31, 2021. We believe that the decline in revenue under the Amgen agreement is temporary because the total revenue from the collaboration is fixed and recognized as research activities are performed.

We did not achieve any milestones or receive any royalty payments in connection with our collaboration agreements during the presented periods.

25

Research and Development Expenses

The following table summarizes our research and development expenses for the periods indicated:

Our research and development expenses increased from €12.2 million for the three months ended March 31, 2020 to €23.0 million for the three months ended March 31, 2021. External research and development expenses increased from €7.4 million for the three months ended March 31, 2020 to €12.8 million for the three months ended March 31, 2021. The increase resulted from higher preclinical and clinical work performed, resulting in an increase in ACT expenses, mainly due to the ramp-up of additional clinical trial sites in the United States and in Europe. Furthermore, the direct research and development cost for TCR Bispecifics increased due to the start of process development and optimization for GMP manufacturing of our TCER lead candidate, IMA401, in 2020. Expenses related to collaboration agreements increased primarily due to the start of the new collaboration with GSK signed in 2019 that was in the start-up phase during the three months ended March 31, 2020 and was ramped up during 2020.

Personnel related research and development expenses, excluding share-based compensation, increased from €4.4 million for the three months ended March 31, 2020 to €5.4 million for the three months ended March 31, 2021. The increase mainly resulted from increased research and development headcount.

Share-based compensation expenses increased from €0.4 million for the three months ended March 31, 2020 to €4.9 million for the three months ended March 31, 2021. The increase resulted from the modification of previous awards as part of the ARYA merger and share-based awards issued under the 2020 Equity Plan.

General and Administrative Expenses

The following table summarizes our general and administrative expenses for the periods indicated:

General and administrative expenses increased from €6.2 million for the three months ended March 31, 2020 to €8.4 million for the three months ended March 31, 2021.

Share-based compensation expenses increased from €0.3 million for the three months ended March 31, 2020 to €3.4 million for the three months ended March 31, 2021. The increase resulted from the modification of previous awards as part of the ARYA merger and share-based awards issued under the 2020 Equity Plan.

Personnel related general and administrative expenses, excluding share-based compensation, increased from €1.6 million for the three months ended March 31, 2020 to €2.0 million for the three months ended March 31, 2021. The increase mainly resulted from an increased headcount in our finance, human resources and communications functions.

Professional and consulting fees decreased from €3.2 million for the three months ended March 31, 2020 to €1.5 million for the three months ended March 31, 2021. The decrease in professional and consulting fees resulted mainly from a decrease in accounting, audit and legal fees. The decrease was due to the one-time expenses associated with the ARYA Merger and PIPE Financing in 2020.

26

Other external expenses marginally increased from €1.2 million for the three months ended March 31, 2020 to €1.5 million for the three months ended March 31, 2021. The increase in other expenses mainly resulted from increased insurance payments, depreciation, and expenses for office equipment.

Other Income

Other income increased from €0.1 million for the three months ended March 31, 2020 to €0.2 million for the three months ended March 31, 2021.

Financial Result

Financial income increased from €2.7 million for the three months ended March 31, 2020 to €3.5 million for the three months ended March 31, 2021. The increase mainly resulted from interest and income from financial instruments.

Financial expenses increased from €0.03 million for the three months ended March 31, 2021 to €1.2 million for the three months ended March 31, 2021. The increase mainly resulted from negative development of USD-EUR forward contracts.

Subsequent to the Business Combination, there were 7,187,500 warrants outstanding, which were classified as financial liabilities through profit and loss. The warrants entitle the holder to purchase one ordinary share at an exercise price of $11.50 per share. The warrants will expire five years after the completion of the Business Combination or earlier upon redemption or liquidation in accordance with their terms.

The fair value of the immatics warrants increased from €2.35 per warrant as of December 31, 2021 to €2.52 as of March 31, 2021. The result is a increase in fair value of warrant liabilities of €1.2 million for the three months ended March 31, 2021.

Liquidity and Capital Resources

Sources of Liquidity

We have funded our operations primarily from private placements of our ordinary shares, proceeds from collaborators, and the net proceeds generated from the ARYA Merger and PIPE Financing that closed on July 1, 2020.

Cash and cash equivalents decreased from €207.5 million as of December 31, 2020 to €195.3 million as of March 31, 2021. Cash and cash equivalents are invested in accordance with our investment policy with an emphasis on liquidity and capital preservation, and consist primarily of cash in banks and money market accounts. Additionally, we invest funds in short-term deposits with an original maturity between three and nine months.

Cash Flows

The following table summarizes our cash flows for each period presented:

Operating Activities

We primarily derive cash from our collaboration agreements. Our cash used in operating activities is significantly influenced by our use of cash for operating expenses and working capital to support the business.

We experienced a net cash outflow for the three months ended March 31, 2021 and 2020, primarily effected by an increase of net loss and working capital changes.

Our net cash outflow from operating activities for the three months ended March 31, 2021 was €16.7 million. This comprised of a net loss of €22.8 million; an decrease in working capital of €4.8 million; and a partial offset of €10.9 million by non-cash charges, mainly from the equity settled shared-based compensation expenses for employees of €8.3 million. The decrease in working capital mainly resulted from a increase in accounts payable and other liabilities of €6.6 million, and an decrease in both accounts receivables and other current assets and prepayments of €0.7 million and €1.2 million, respectively.

27

For the three months ended March 31, 2020, our net cash outflow from operating activities was €11.5 million. This resulted from a €3.2 million decrease in working capital, a net loss of €8.6 million, and a partial offset of €0.3 million from non-cash charges. This decrease in working capital mainly resulted from a increase in accounts payable and other liabilities of €3.3 million, a increase in other assets of €0.4 million, and an decrease in accounts receivable of €0.6 million.

Investing Activities

Our net inflow of cash from investing activities for the three months ended March 31, 2021 was €2.6 million. This consisted of €3.1 million net proceeds from investments that are classified as other financial assets and held with financial institutions to finance the company and €0.6 million payment for new equipment.

Net cash used in investing activities for the three months ended March 31, 2020 was €19.2 million. This consisted of a €2.4 million payment for new equipment; our new laboratory space, computers, office, and other laboratory equipment; as well as €16.8 million of net cash paid for investments that are classified as other financial assets and held with financial institutions to finance the company.

The increase in investing activities, other than cash flows from investments in financial assets, reflects the increase in our research and development activities. We intend to use the additional lab space and acquired equipment to expand our research and development efforts, especially with regard to our clinical pipeline candidates in ACTengine as well as our preclinical pipeline candidates in TCER Bispecifics.

Financing Activities

During the three months ended March 31, 2021, net cash used from financing activities amounted to €0.5 million. This was mainly driven by the principal portion of payments in connection with lease contracts in the amount of €0.5 million.

During the three months ended March 31, 2020, net cash used in financing activities was €0.6 million, resulting from the payment of the principal portion of lease liabilities.

Operation and Funding Requirements

Historically, we have incurred significant losses due to our substantial research and development expenses. We have an accumulated deficit of €467.3 million as of March 31, 2021. We expect our expenses to increase in connection with our ongoing activities, particularly as we continue the research and development of, continue or commence clinical trials of, and seek regulatory approval for, our product candidates. We believe that we have sufficient financial resources available to fund our projected operating requirements for at least the next twelve months. Because the outcome of our current and planned clinical trials is highly uncertain, we cannot reasonably estimate the actual amounts necessary to successfully complete the development and commercialization of our product candidates. For example, our costs will increase if we experience any delays in our current and planned clinical trials. Our future funding requirements will depend on many factors, including, but not limited to:

28

Identifying potential product candidates and conducting preclinical studies and clinical trials is a time-consuming, expensive and uncertain process that takes many years to complete, and we may never generate the necessary data or results required to obtain regulatory approval and commercialize our product candidates. In addition, our product candidates, if approved, may not achieve commercial success. Our commercial revenues, if any, will be derived from sales of products that we do not expect to be commercially available for many years, if at all. Accordingly, we will need to continue to rely on additional financing to achieve our business objectives. Adequate additional financing may not be available to us on acceptable terms, or at all.

Unless and until we can generate sufficient revenue to finance our cash requirements, which may never happen, we may seek additional capital through a variety of means, including through public and private equity offerings and debt financings, credit and loan facilities and additional collaborations. If we raise additional capital through the sale of equity or convertible debt securities, our existing shareholders’ ownership interest will be diluted, and the terms of such equity or convertible debt securities may include liquidation or other preferences that are senior to or otherwise adversely affect the rights of our existing shareholders. If we raise additional capital through the sale of debt securities or through entering into credit or loan facilities, we may be restricted in our ability to take certain actions, such as incurring additional debt, making capital expenditures, acquiring or licensing intellectual property rights, declaring dividends or encumbering our assets to secure future indebtedness. Such restrictions could adversely impact our ability to conduct our operations and execute our business plan. If we raise additional capital through collaborations with third parties, we may be required to relinquish valuable rights to our intellectual property or product candidates or we may be required to grant licenses for our intellectual property or product candidates on unfavorable terms. If we are unable to raise additional capital when needed, we may be required to delay, limit, reduce or terminate our product development efforts or we may be required to grant rights to third parties to develop and market our product candidates that we would otherwise prefer to develop and market ourselves. For more information as to the risks associated with our future funding needs, see “Risk Factors—Risks Related to Our Financial Position” in our annual report filed on form 20-F with the Securities and Exchange Commission on March 30, 2021.

Off-Balance Sheet Arrangements

During the periods presented, we did not have any off-balance sheet arrangements that have or are reasonably likely to have a current or future effect on our financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources.

29

Contractual Obligations and Commitments

The following table summarizes our contractual obligations as of December 31, 2020 and the effects that such obligations are expected to have on our liquidity and cash flows in future periods:
