Item 2.02.

Results of Operations and Financial Condition.

Immunocore Holdings plc (the “Company”) expects to report preliminary unaudited net product revenue (“net sales”) arising from the sales of KIMMTRAK (tebentafusp) of approximately $66 million for the fourth quarter of 2023 and approximately $235 million for the full year 2023 in accordance with U.S. general accepted accounting principles (“U.S. GAAP”). In the fourth quarter of 2023, KIMMTRAK sales growth came primarily from continued commercial progress in the United States. Additionally, due primarily to increases in commercial and clinical expenses, the Company expects its research and development (“R&D”) expenses and selling, general and administrative (“SG&A”) expenses will increase when compared to such expenses for the third quarter of 2023. The increases in R&D expenses and SG&A expenses described do not include unrealized foreign exchange losses on the translation of monetary foreign currency balances. Under U.S. GAAP, the Company will report foreign exchange gains and losses on a separate line below “Operating (loss)/ income” on the Company’s consolidated statements of operations and comprehensive loss. The Company’s financials were previously prepared in accordance with International Financial Reporting Standards (“IFRS”), as issued by the International Accounting Standards Board. Under IFRS, “foreign exchange gains and losses” were previously reported within total SG&A expenses in the Company’s financial statements.

The Company’s preliminary unaudited cash and cash equivalents at December 31, 2023 was approximately $443 million.

The Company’s audited consolidated financial statements at and for the year ended December 31, 2023 are not yet available. As a result, the financial information described in this Item 2.02 is preliminary and unaudited, and represents management’s estimate as of the date of this Current Report on Form 8-K, and is subject to completion of the Company’s financial closing procedures for the fourth quarter and fiscal year ended December 31, 2023. These preliminary results may materially differ from the actual results that will be reflected in the Company’s audited consolidated financial statements when they are completed and publicly disclosed. The Company’s independent registered public accounting firm has not conducted an audit or review of, and does not express an opinion or any other form of assurance with respect to, the Company’s preliminary results.

The financial information presented in this Item 2.02 does not present all necessary information for a complete understanding of the Company’s financial condition as of December 31, 2023, or the Company’s results of operations for the year ended December 31, 2023. This preliminary financial data should not be viewed as a substitute for full financial statements for the year ended December 31, 2023 prepared in accordance with U.S. GAAP. Effective January 1, 2024, the Company’s financial statements will be audited in accordance with U.S. GAAP. Prior to January 1, 2024, the Company qualified as a foreign private issuer and its historical financial statements were prepared in accordance with IFRS.

Item 8.01

Exhibit 99.2

In the confidential preliminary offering memorandum to be used in connection with a private placement to persons reasonably believed to be qualified institutional buyers pursuant to Rule 144A of the Securities Act of 1933, as amended, by Immunocore Holdings plc, the Company provided the following overview of the Company’s business as updates or supplements to the information provided in the Company’s previous periodic filings with the Securities and Exchange Commission. Unless the context requires otherwise, “Immunocore,” “Company,” “we,” “our,” and “us” refers to Immunocore Holdings plc and its subsidiaries.

Overview

We are a commercial stage biotechnology company pioneering the development of a novel class of TCR bispecific immunotherapies called ImmTAX – Immune mobilizing monoclonal TCRs Against X disease – designed to treat a broad range of diseases, including cancer, infectious and autoimmune diseases. Leveraging our proprietary, flexible, off-the-shelf ImmTAX platform, we are developing a deep pipeline in multiple therapeutic areas, including five clinical stage programs in oncology and infectious disease, advanced pre-clinical programs in autoimmune disease and earlier pre-clinical programs across three therapeutic areas.

In 2022, we received approval for our lead product, KIMMTRAK, for the treatment of unresectable metastatic uveal melanoma, or mUM, from the U.S. Food and Drug Administration, or the FDA, the European Commission, or the EC, and other health authorities. KIMMTRAK is the lead product from our ImmTAX platform and is the first new therapy in uveal melanoma in four decades. To date, we have dosed over 1,000 cancer patients with KIMMTRAK, tebentafusp, and our other ImmTAX product candidates, which we believe is the largest clinical data set of any bispecific in a solid tumor and any TCR therapeutic. Our other clinical programs are being conducted with patients who have a broad range of cancers including melanoma, ovarian, lung, endometrial, colorectal, and gastrointestinal cancers, among others. We believe the other ImmTAX product candidates we have under development have the potential to address other tumor types with larger addressable patient populations and significant unmet need.

Our ImmTAC Platform (Oncology)

•

KIMMTRAK (tebentafusp), our ImmTAC molecule targeting an HLA-A*02:01 gp100 antigen, is our first approved product. The FDA and the EC have approved KIMMTRAK (tebentafusp-tebn and tebentafusp, respectively) for the treatment of HLA-A*02:01-positive adult patients with unresectable mUM. KIMMTRAK is currently approved in 38 countries. We have commercially launched KIMMTRAK in the United States and nine other countries, with further commercial launches underway in additional territories where we have received regulatory approval.

•

KIMMTRAK is also being evaluated for the treatment of advanced cutaneous melanoma, or CM. We are currently enrolling patients in a randomized Phase 2/3 clinical trial (TEBE-AM) to investigate the potential of tebentafusp as a monotherapy or in connection with an anti-PD(L)1 therapy. This trial is enrolling patients with advanced CM, excluding only uveal melanoma, who have progressed on an anti-PD1, received prior ipilimumab and, if applicable, received a tyrosine kinase inhibitor, or TKI. Randomization is expected to be completed in the Phase 2 portion of the trial during the third quarter of 2024, and we expect topline data from the Phase 2 portion of the trial to be available by the fourth quarter of 2024.

•

KIMMTRAK will also be evaluated for the treatment of adjuvant therapy for uveal (or ocular) melanoma. In 2023, we signed an agreement for a European Organisation for Research and Treatment of Cancer (EORTC)-sponsored trial to study KIMMTRAK as adjuvant therapy for uveal (or ocular) melanoma (ATOM) in HLA-A*02:01 positive patients. We anticipate that the EORTC will randomize the first patient in the trial in the second half of 2024.

•

IMC-F106C, our ImmTAC molecule targeting an HLA-A*02 PRAME antigen, is currently being evaluated in a Phase 1/2 dose escalation clinical trial in patients with multiple solid tumor cancers and is advancing towards a registrational Phase 3 clinical trial in first-line advanced CM, in combination with a checkpoint inhibitor. In addition to progressing IMC-F106C into a registrational trial in CM, we are continuing to enroll patients in the monotherapy and combination arms of the Phase 1/2 clinical trial across multiple tumor types, including expansion arms for patients with advanced ovarian, non-small cell lung, and endometrial carcinoma. The initial data from the Phase 1 clinical trial of IMC-F106C, the first PRAME x CD3 ImmTAC bispecific protein, was presented at the 2022 European Society for Medical Oncology, or ESMO, Congress in September 2022. Durable Response Evaluation Criteria in Solid Tumors, or RECIST, responses and reduction in circulating tumor DNA, or ctDNA, were observed across multiple solid tumors. In August 2023, we provided an updated analysis of the initial eighteen uveal and cutaneous melanoma patients in the data set presented at ESMO 2022, which continued to show promising durability of the clinical activity (range of duration of patient response from 6 months to 17 months). We expect to report data from the ongoing monotherapy and combination cohorts throughout 2024 including CM (expected in the second quarter of 2024), ovarian (expected by third quarter of 2024), and non-small cell lung carcinoma (expected by fourth quarter of 2024). We have decided to advance IMC-F106C into a Phase 3 first-line CM clinical trial in combination with nivolumab with a primary endpoint of progression-free survival, or PFS, based on our analysis of the ongoing Phase 1 data in previously treated CM which demonstrated monotherapy clinical activity including partial responses (PR), durable tumor reduction, disease control (PR and SD), PFS and ctDNA reduction (consistent with prior reported data for IMC-F106C and tebentafusp). Additional rationale includes safety in combination with checkpoints (from the ongoing Phase 1 data and prior experience with tebentafusp) and evidence from across the platform for increased clinical activity in earlier line patients compared to later line. As such, PRISM-MEL-301, the first PRAME Phase 3 clinical trial with IMC-F106C, will randomize patients with HLA-A*02:01-positive, first-line advanced CM to IMC-F106C + nivolumab versus a control arm of either nivolumab or nivolumab + relatlimab, depending on the country where the patient is enrolled. We plan to randomize the first patient in this trial in the first quarter of 2024.

•

IMC-P115C, our half-life extended ImmTAC molecule targeting an optimal HLA-A*02 PRAME, is advancing towards an investigational new drug, or IND, application or clinical trial application, or CTA, submission for IMC-P115C in the second quarter of 2024. This ImmTAC candidate was designed with the aim of improving patient convenience. IMC-P115C targets the same PRAME-A02 peptide and uses the same CD3 end and T-cell-receptor, or TCR, specificity as IMC-F106C.

•	IMC-T119C, our ImmTAC molecule targeting an optimal HLA-A*24 PRAME, is advancing towards an IND application or CTA submission for IMC-T119C in the second half of 2024. HLA-24 is an HLA-type that is estimated to be present in 60% of people in Japan and 15-20% in Western populations.

•

IMC-R117C, our ImmTAC molecule targeting an optimal HLA-A*02 PIWIL1, will enter a Phase 1 clinical trial in 2024. We submitted a CTA in December 2023. PIWIL1 is believed to play a role in tumor progression and is expressed across a range of tumors including colorectal, which is historically insensitive to immune checkpoints, as well as other gastrointestinal cancers. PIWIL1 is also reported to be a negative prognostic marker. We believe IMC-R117C is the first PIWIL1 targeted immunotherapy.

Our ImmTAV Platform (Infectious Diseases)

•

IMC-M113V, our ImmTAV molecule targeting a human immunodeficiency virus gag antigen bispecific TCR molecule, is expected to be evaluated in a Phase 1 clinical trial for which we are currently enrolling patients. Our goal is to develop a functional cure for HIV. Initial Phase 1 safety and pharmacodynamic activity data from the single ascending dose, or SAD, portion of the trial was presented at the Conference on Retroviruses and Opportunistic Infections (CROI) in 2023. IMC-M113V was well tolerated at doses where we observed biomarkers of T cell engagement. We are enrolling up to 28 participants living with HIV in the multiple ascending dose, or MAD, part of the trial, to identify a safe and tolerable dosing schedule that could lead to reduction in the viral reservoir and control of HIV after stopping antiretroviral therapies, or functional cure. We expect to present a data update from the Phase 1 clinical trial in the second half of 2024.

•

IMC-I109V, our ImmTAV molecule targeting a conserved hepatitis B virus envelope antigen, is currently being evaluated in a Phase 1 clinical trial in patients with chronic HBV who are non-cirrhotic, hepatitis B e-Antigen negative, and virally suppressed on chronic nucleot(s)ide analogue therapy. In 2023, we amended the trial design in the ongoing Phase 1 trial with IMC-I109V for people living with HBV to include HBV-positive hepatocellular carcinoma. Our goal is to develop a functional cure for HBV. We are enrolling patients in the SAD portion of the trial.

Our ImmTAAI Platform (Autoimmune Diseases)

•

IMC-S118AI, our ImmTAAI molecule specifically targeted to the pancreatic beta-cell for disease modifying treatment in type 1 diabetes, will be advancing towards GMP manufacturing in 2024. IMC-S118AI recognizes a peptide from pre-proinsulin presented by HLA-A2*01 on beta-cells coupled with a PD1 agonist effector arm. Type 1 diabetes is an autoimmune condition in which the patient’s immune system attacks and kills the beta-cells responsible for controlling glucose levels through the release of insulin. Progressive loss of beta cells leads to loss of glucose control requiring life-long monitoring and treatment with exogenous insulin. We believe IMC-S118AI has the potential to provide a differentiated option for treatment with advantages of tissue-specific down modulation without immunosuppression.

•

Undisclosed universal skin antigen-presenting cells, or APCs, targeted ImmTAAI, our ImmTAAI molecule targeting a non-HLA restricted or ‘universal’ target expressed on APCs in the skin. APCs, through their role of priming and restimulating T cells are believed to play a role in many autoimmune and inflammatory diseases. We believe that precision targeting of our PD1 agonist based immune inhibitory molecule to these key cells involved in the establishment and maintenance of disease will provide clinical benefit to patients and the potential to modify the course of disease. We are considering this target for treatment of a range of dermatological diseases.
