2.1.

Going concern

Since inception, the Group’s activities have consisted primarily of raising capital and performing research and development activities to advance its technologies. The Group is still in the development phase and has not yet marketed any products commercially. Immatics’ ongoing success depends on the successful development and regulatory approval of its products and its ability to finance operations. The Group will seek additional funding to reach its development and commercialization objectives.

The Group plans to seek funds through further private or public equity financings, debt financings, collaboration agreements and marketing, distribution or licensing arrangements. The Group may not be able to obtain financing or enter into collaboration or other arrangements on acceptable terms. If the Group is unable to obtain funding, it could be forced to delay, reduce or eliminate some or all of its research and development programs, product portfolio expansion or commercialization efforts, which could adversely affect its business prospects. However, Immatics’ cash and cash equivalents and other financial assets will be sufficient to fund operating expenses and capital expenditure requirements for at least 12 months from the issuance date of the financial statements.

The accompanying consolidated financial statements have been prepared on a going concern basis. This contemplates the Group will continue in operation for the foreseeable future and will be able to realize its assets and discharge its liabilities in the normal course of operations. The consolidated financial statements do not reflect any adjustments relating to the recoverability and classification of assets or the amounts and classification of liabilities that would be necessary, were the Group unable to continue as a going concern
