Actual results may differ from those set forth in this Quarterly Report on Form 10-Q due to the risks and uncertainties inherent in our business, including, without limitation: the FDA may not agree with our interpretation of the results of its clinical trials; later developments with the FDA that may be inconsistent with already completed FDA meetings; the preliminary clinical results, including efficacy and safety results, from ongoing Phase 2 and Phase 3 trials may not be reflected in the final analyses of these trials including new cohorts within these trials; the results obtained in our ongoing clinical trials, such as the studies and trials referred to in this Quarterly Report on Form 10-Q, may not be indicative of results obtained in future clinical trials or supportive of product approval; regulatory authorities may potentially delay the timing of FDA or other regulatory authority approval of, or other action with respect to, our product candidates, specifically, our description of FDA interactions are subject to FDA’s interpretation, as well as FDA’s authority to request new or additional information; we may not be able to obtain or maintain FDA or other regulatory authority approval of its product candidates; our ability to address FDA or other regulatory authority requirements relating to our clinical programs and registrational plans, such requirements including, but not limited to, clinical and safety requirements as well as manufacturing and control requirements; risks related to our accelerated FDA review designations; our ability to obtain and maintain intellectual property rights relating to our product pipeline; and the acceptance by the market of our product candidates and their potential reimbursement by payors, if approved.

We caution you that the risks, uncertainties and other factors referenced above may not contain all the risks, uncertainties and other factors that are important to you. In addition, we cannot guarantee future results, level of activity, performance or achievements. Any forward-looking statement made by us in this Quarterly Report on Form 10-Q speaks only as of the date of this Quarterly Report on Form 10-Q or as of the date on which it is made. Except as required by law, we undertake no obligation to publicly update any forward-looking statements, whether because of new information, future events or otherwise, after the date of this Quarterly Report on Form 10-Q.

NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

NOTE 1. GENERAL ORGANIZATION, BUSINESS AND LIQUIDITY

General Organization and Business

Iovance Biotherapeutics, Inc. (the “Company”) is a biopharmaceutical company pioneering a transformational approach to treating cancer by harnessing the human immune system’s ability to recognize and destroy diverse cancer cells using therapies personalized for each patient. The Company’s mission is to be the global leader in innovating, developing and delivering tumor infiltrating lymphocyte (“TIL”) therapies for patients with solid tumor cancers. The Company’s autologous TIL therapy platform uses a centralized, scalable, and proprietary 22-day manufacturing process to grow polyclonal T-cells unique to each patient and yields a cryopreserved, individualized therapy. In May 2023, the Company acquired the worldwide rights to Proleukin® (aldesleukin), a commercialized interleukin-2 (“IL-2”) product used to promote T-cell activity following TIL infusion. The acquisition of Proleukin® provides a new revenue source, secures the IL-2 supply chain and logistics surrounding TIL therapy administration, and lowers cost of goods and clinical trial expenses for Proleukin® used with TIL therapies.

The Company is currently conducting clinical trials to investigate multiple TIL therapies for multiple indications, including its lead product candidate, lifileucel, for advanced, or metastatic or unresectable, melanoma. The Company completed a rolling Biologics License Application (“BLA”) submission to the U.S. Food and Drug Administration (the “FDA”) for lifileucel for patients with advanced melanoma in March 2023, and the FDA accepted its BLA and granted lifileucel Priority Review in May 2023. The FDA originally assigned November 25, 2023 as the target action date for a decision under the Prescription Drug User Free Act (“PDUFA”); the target action date was recently updated by the FDA to February 24, 2024. The Company is also pursuing registrational strategies for lifileucel in advanced cervical cancer and for its TIL therapy LN-145 in metastatic non-small cell lung cancer (“NSCLC”). In addition, the Company is investigating next generation approaches to optimize TIL products, manufacturing processes and treatment regimens, including a first-in-human clinical trial of its lead genetically modified TIL therapy, IOV-4001. The Company is also exploring a shorter manufacturing process, tumor tissue procurement via core biopsy, additional genetically modified TIL therapies including multiple immune checkpoint gene edits, and cytokine-tethered TIL therapies, as well as a novel IL-2 analog, designated IOV-3001, as potential avenues to improve efficacy, manufacturing timelines, sample collection and supportive treatments involved in the overall TIL therapy process and treatment regimen.

Basis of Presentation of Unaudited Condensed Consolidated Financial Information

The accompanying unaudited condensed consolidated financial statements of the Company for the three and nine months ended September 30, 2023 and 2022 have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and pursuant to the requirements for reporting on Form 10-Q and Regulation S-X. Accordingly, they do not include all the information and footnotes required by GAAP for audited financial statements. However, such information reflects all adjustments (consisting solely of normal recurring adjustments), which are, in the opinion of management, necessary for the fair presentation of the Company's financial position and results of operations. Results shown for interim periods are not necessarily indicative of the results that may be expected for the year ended December 31, 2023 or for any other period. The condensed consolidated balance sheet as of December 31, 2022 was derived from the audited consolidated financial statements included in the Company's Annual Report on Form 10-K filed with the U.S. Securities and Exchange Commission (the “SEC”) on February 28, 2023. These interim financial statements should be read in conjunction with that report. The reporting currency of the Company is U.S. dollars. The functional currency for most of its foreign subsidiaries is their local currency.

Liquidity

The Company is currently engaged in the development of therapeutics to fight solid tumor cancers. With the completion of the rolling BLA submission for lifileucel for advanced melanoma in March 2023, the Company expects to generate revenue from the sale of its product lifileucel, if the BLA is approved. Furthermore, upon the completion of the closing of the acquisition of the worldwide rights to Proleukin® (as discussed below in Note 4 - Proleukin® Acquisition) in the second quarter of 2023, the Company generated revenue from the sales of Proleukin® during the three and nine months ended September 30, 2023. However, such revenues for Proleukin® and lifileucel may not be material during the 12 months from the date these condensed consolidated financial statements are issued. The Company has incurred a net loss of $327.7 million for the nine months ended September 30, 2023 and used $277.9 million of cash in its operating activities during the nine months ended September 30, 2023. As of September 30, 2023, the Company

10

had $427.8 million in cash, cash equivalents, investments, and restricted cash ($267.7 million of cash and cash equivalents, $93.7 million in short-term investments and $66.4 million in restricted cash).

The Company expects to continue to incur significant expenses to support its preparations for the commercialization and launch of lifileucel (if approved), including continuing to prepare the Iovance Cell Therapy Center (the “iCTC”), its manufacturing facility in Philadelphia, to support the Company’s ongoing and planned clinical programs, including its NSCLC registration directed study and its frontline advanced melanoma Phase 3 confirmatory trial, TILVANCE-301, to expand the combination of TIL and immune checkpoint inhibitors (“ICI’s”) in ICI naïve patient cohorts, and to support Proleukin® integration activities during 2023 and beyond. Based on the funds the Company has available as of the date these condensed consolidated financial statements are issued, the Company believes that it has sufficient capital to fund its anticipated operating expenses and capital expenditures as planned for at least the next twelve months from the date these condensed consolidated financial statements are issued.

Concentrations of Risk

The Company is subject to credit risk from its portfolio of cash, cash equivalents, trade accounts receivable and investments. Under its investment policy, the Company limits amounts invested in securities by credit rating, maturity, industry group, investment type and issuer, except for securities issued by the U.S. government. The Company does not believe it is exposed to any significant concentrations of credit risk from these financial instruments. The goals of its investment policy are safety and preservation of principal, diversification of risk, and liquidity of investments sufficient to meet cash flow requirements.

NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Cash, Cash Equivalents, and Investments

The Company’s cash and cash equivalents include short-term investments with original maturities of three months or less when purchased. The Company's investments are classified as “available-for-sale.” The Company includes these investments in current assets or non-current assets in the condensed consolidated balance sheets based on the length of maturity from the reporting date and carries them at fair value. Unrealized gains and losses on available-for-sale securities are recorded in the condensed consolidated statements of comprehensive loss. Impairment losses related to credit losses (if any) are recorded as an allowance for credit losses with an offsetting entry to Interest income, net. No impairment losses related to credit losses were recognized for the three and nine months ended September 30, 2023 and 2022. The cost of debt securities is adjusted for the amortization of premiums and accretion of discounts to maturity. Such amortization and accretion are included in Interest income, net in the condensed consolidated statements of operations. Gains and losses on securities sold are recorded based on the specific identification method and are included in Interest income, net in the condensed consolidated statements of operations. The Company has not incurred any realized gains or losses from sales of securities to date. The Company’s investment policy limits investments to certain types of instruments such as certificates of deposit, money market instruments, obligations issued by the U.S. government and U.S. government agencies as well as corporate debt securities and commercial paper, and places restrictions on maturities and concentration by type and issuer, except for securities issued by the U.S. government.

Restricted Cash

The Company maintains a required minimum balance in a segregated bank account in connection with its letters of credit for which amounts are restricted as to their use by the Company. Currently, the Company’s letters of credit are primarily comprised of one for the benefit of the landlord for the iCTC used as a security deposit for the lease in the amount $5.45 million and one for $0.6 million for the benefit of the landlord for the Company’s current headquarters’ lease (See Note 12 - Leases), as well as one for $60.0 million, for the future milestone payment as required by the terms of the Option Agreement for the Proleukin® acquisition (See Note 4 – Proleukin® Acquisition). The letter of credit for $5.45 million originally expired on May 28, 2020, however, it automatically extends for additional one-year periods, without written agreement, to May 28 in each succeeding calendar year, through at least 60 days after the lease expiration date. Further, on the expiration of the seventh year of the lease, and each anniversary date thereafter, the letter of credit may be decreased by $1.0 million with a minimum security deposit of $1.5 million maintained through the end of the lease term. The letter of credit with the landlord for the Company’s current headquarters’ lease expires on February 1, 2032, however, it will be automatically extended, without written agreement, for one-year periods to February in each succeeding calendar year. The letter of credit for the $60.0 million expires on May 5, 2024, however, it will be automatically extended, without written agreement, for one-year periods to May in each succeeding calendar year and the final expiration date will be July 20, 2026. Furthermore, the letter of credit will not be automatically extended if a thirty-day written notice is provided prior to the annual extension. As of

11

September 30, 2023 and December 31, 2022, Restricted cash totaled $66.4 million and $6.4 million, respectively, in the Company’s condensed consolidated balance sheets.

The following table provides a reconciliation of cash, cash equivalents, and restricted cash, reported within the condensed consolidated balance sheets that sum to the total of the same such amounts shown in the condensed consolidated statements of cash flows (in thousands):
