Forward-Looking Statements
Certain matters discussed in this presentation are “forward-looking statements” of Iovance Biotherapeutics, Inc. (hereinafter referred to as the “Company,” “we,” “us,” or “our”) within the
meaning of the Private Securities Litigation Reform Act of 1995 (the “PSLRA”). Without limiting the foregoing, we may, in some cases, use terms such as “predicts,” “believes,” “potential,”
“achievable,” “continue,” “estimates,” “anticipates,” “expects,” “plans,” “intends,” “forecast,” “guidance,” “outlook,” “may,” “can,” “could,” “might,” “will,” “should,” or other words
that convey uncertainty of future events or outcomes and are intended to identify forward-looking statements. Forward-looking statements are based on assumptions and assessments
made in light of management’s experience and perception of historical trends, current conditions, expected future developments, and other factors believed to be appropriate. Forward-looking statements in this presentation are made as of the date of this presentation, and we undertake no duty to update or revise any such statements, whether as a result of new
information, future events or otherwise. Forward-looking statements are not guarantees of future performance and are subject to risks, uncertainties, and other factors, many of which are
outside of our control, that may cause actual results, levels of activity, performance, achievements, and developments to be materially different from those expressed in or implied by
these forward-looking statements. Important factors that could cause actual results, developments, and business decisions to differ materially from forward-looking statements are
described in the sections titled "Risk Factors" in our filings with the U.S. Securities and Exchange Commission, including our most recent Annual Report on Form 10-K and Quarterly
Reports on Form 10-Q, and include, but are not limited to, the following substantial known and unknown risks and uncertainties inherent in our business: the risks related to our ability to
successfully commercialize our products; the acceptance by the market of our products and product candidates, if approved, and their potential pricing and/or reimbursement by payors,
and whether such acceptance is sufficient to support continued commercialization or development of our products or product candidates; the risk regarding our ability to manufacture our
therapies at our Iovance Cell Therapy Center facility, including the risk that our ability to increase manufacturing capacity at our facility may adversely affect our commercial launch; the
risks related to our ability to obtain, maintain and enforce patent and other intellectual property protection for our products and product candidates; the risk that the successful
development or commercialization of our products may not generate sufficient revenue from product sales, and we may not become profitable in the near term, or at all; the risks related
to the timing of and our ability to successfully develop, submit, obtain, or maintain regulatory authority approval of our product candidates; whether clinical trial results from our pivotal
studies and cohorts, and meetings with regulatory authorities may support registrational studies and subsequent approvals by regulatory authorities, including the risk that the planned
registrational trial in advanced sarcomas may not support approval; preliminary and interim clinical results, which may include efficacy and safety results, from ongoing clinical trials or
cohorts may not be reflected in the final analyses of our ongoing clinical trials or subgroups within these trials or in other prior trials or cohorts; the risk that we may be required to conduct
additional clinical trials or modify ongoing or future clinical trials based on feedback from regulatory authorities; the risk that our interpretation of the results of our clinical trials or
communications with regulatory authorities may differ from the interpretation of such results or communications by such regulatory authorities; the risk that clinical data from ongoing
clinical trials of Amtagvi will not continue or be repeated in ongoing or planned clinical trials or may not support regulatory approval or renewal of authorization; the risk that unanticipated
expenses may decrease our estimated cash balances and forecasts and increase our estimated capital requirements; the risk that we may not be able to recognize revenue for our
products; the risk that Proleukin revenues, and other factors such as the number of authorized treatment centers, may not serve as a leading indicator for Amtagvi revenues; the risks
regarding our anticipated operating and financial performance, including our financial guidance and projections; the effects of global and domestic geopolitical factors or public health
events; and other factors, including general economic conditions and regulatory developments, not within our control. Any financial guidance provided in this presentation assumes the
following: no material change in our ability to manufacture our products; no material change in payor coverage; no material change in revenue recognition policies; no new business
development transactions not completed as of the period covered by this presentation; and no material fluctuation in exchange rates.

FDA Fast Track Designation in Second-Line Nonsquamous mNSCLC
1.Interim data cut as of October 10, 2025 of patients with nonsquamous NSCLC with minimum cell dose based on FDA feedback in melanoma. Patients progressed on or after chemotherapy and anti-PD-1 therapy for mNSCLC without EGFR, ROS1 or ALK
genomic mutations and received at least one line of FDA-approved targeted therapy if indicated by other actionable tumor mutations. 2. Time to response, time on assessment for confirmed responders (PR or better). A bar is presented for each patient
starting from date of lifileucel infusion up to date of new anti-cancer therapy, end of assessment, death, or data cutoff date, whichever occurs earlier. *Patient 23 in ongoing follow up to confirm PR.

PD-1
PD-1 inhibits the ability
of T cells to fight cancer:
T cells, upon encountering
cancer cells, produce PD-1, a
checkpoint receptor that is
activated by proteins (PD-L1
and PD-L2) found on cancer
and other immune cells.1

IOV-3001: Next Generation IL-2 for TIL Supportive Regimen1,2
Phase 1/2 trial enrolling patients
Recombinant fusion protein
designed to enhance TIL survival
and cellular proliferation
• A modified copy of the coding sequence
for aldesleukin (mdIL-2) is fused to a
humanized monoclonal immunoglobulin
(Ig)G1κ antibody
• The mdIL-2 moiety of IOV-3001 binds to
the IL-2-receptor (IL-2R) with subsequent
phosphorylation of signal transducer and
activator of transcription 5 (STAT5),
resulting in enhanced performance

• Tethered IL-12 TIL cells can improve efficacy by
remodeling the suppressive TME into an immuno-supportive state
– In advanced melanoma patients, an ORR of 63% (n=16) was
observed with prior generation IL-12 secreting TIL product at doses
10- to 100-fold lower than conventional TIL products1
• IL-12 shows independent clinical efficacy, with safe
delivery to the TME being the primary challenge1,2
• Expression of IL-12 on IOV-5001 is induced upon
antigen encounter in the TME1,2
• IOV-5001’s expressed IL-12 is tethered to the
membrane surface of TIL to avoid release into
circulation (shedding) 2
• Inducible IL-12 expression in the TME and lack of IL-12
shedding expected to allow increased IOV-5001 cell
doses and improved TIL efficacy in solid tumor cancers
