(OXFORDSHIRE, England & CONSHOHOCKEN, Penn. & ROCKVILLE, Md., US, 1 March, 2023) Immunocore Holdings plc (Nasdaq: IMCR), a commercial-stage biotechnology company pioneering the development of a novel class of T cell receptor (TCR) bispecific immunotherapies designed to treat a broad range of diseases, including cancer, infectious diseases and autoimmune conditions, today announced its financial results for the fourth quarter and year ended December 31, 2022, and provided a business update.

"We are proud that KIMMTRAK, the world's first commercialized TCR therapy, has been approved in over 30 countries for patients with metastatic uveal melanoma. In 2023, we will make it available to even more patients with launches planned in additional countries and through enrollment of cutaneous melanoma patients into our registrational tebentafusp trial," said **Bahija Jallal, Chief Executive Officer of Immunocore**. "We are also focused on progressing our PRAME clinical programs with ongoing expansion arms in multiple tumor types. Our platform continues to deliver first-in-class oncology programs, like PIWIL1, and several infectious disease candidates."

#### Full Year and Fourth Quarter 2022 Highlights (including post-period)

#### Financial Results
Total net product and net pre-product revenue (or "net sales") arising from the sales of KIMMTRAK (tebentafusp) were £42.3 million (or $51.1 million) in the fourth quarter of 2022, of which £32.1 million (or $38.8 million) was in the United States, £10.1 million (or $12.2 million) in Europe and £0.1 million (or $0.1 million) in international regions. For the year ended December 31, 2022, the Company generated total revenue from the sale of KIMMTRAK and tebentafusp in the amount of £116.8 million (or $141.1 million), of which £80.4 million (or $97.2 million) was in the United States, £35.5 million (or $42.9 million) in Europe and £0.9 million (or $1.1 million) in international regions.

------

R&D expenses for the year 2022 were £89.2 million (or $107.9 million), compared to £73.2 million for the year 2021. Selling and Administrative expenses for the year 2022 were £93.7 million (or $113.2 million), compared to £88.4 million for the year 2021.

Net loss for the fourth quarter of 2022 was £25.2 million (or $30.4 million) compared to a net loss of £39.4 million in the same period in 2021, and full year net loss for 2022 was £41.24 million (or $49.8 million) compared to a full year net loss of £131.5 million in 2021.

The fourth quarter basic and diluted loss per share for was $0.63, compared to $1.21 on December 31, 2021. Basic and diluted loss per share for the year ended December 31, 2022 was $1.09, compared to $4.19 for 2021.

Cash and cash equivalents for the year ended December 31, 2022 were £332.5 million (or $401.6 million). The Company's current cash position and projected KIMMTRAK revenue provides a projected cash runway into 2026.

#### KIMMTRAK<sup>®</sup> (tebentafusp-tebn) for metastatic uveal melanoma
During the fourth quarter of 2022, the Company continued to add new accounts prescribing KIMMTRAK in the United States, Germany, and France. As of December 31, 2022 there were 240 new accounts prescribing KIMMTRAK in the United States, which brings the capture rate of these accounts, according to the Company's internal estimates, to 50% of potentially eligible patients. There were 100 new accounts prescribing KIMMTRAK in Germany and France, which brings the capture rate to approximately 80% of the eligible patient population. In the United States, Germany, and France the commercial team is focused on treating patients closer to home. In the three countries where KIMMTRAK is commercially available the real-world mean duration of treatment for KIMMTRAK continues increasing to the 9 months observed in the Phase 2 and 3 clinical trials.

During the fourth quarter of 2022, the Company received numerous awards and positive recognitions for KIMMTRAK's clinical benefit. In November, the Company was awarded the SCRIP award in the UK in the 'Best New Drug' category, and in December, the prestigious Prix Galien France 2022 award in the 'Medicine in Innovative Therapeutics' category, for KIMMTRAK. KIMMTRAK's clinical benefit to patients was recognized with Germany's G-BA (Gemeinsamer Bundesausschuss) granting the therapy a considerable added benefit rating, as well as in France, where the HAS transparency committee granted an ASMR III and a SMR rating of important. These recommendations build upon the positive recommendations by American Society of Clinical Oncology (ASCO) and National Comprehensive Cancer Network (NCCN) in the second quarter of 2022. KIMMTRAK was approved by the U.S. Food and Drug Administration; the European Commission; and health authorities in the United Kingdom, Australia and Canada in the first half of 2022.

The Company is undergoing reimbursement discussions in a number of countries, including Germany and France where the Company is currently receiving revenues. The Company expects reimbursement decisions in one additional major European country by mid-2023 and up to five smaller countries by end of 2023.

------

In November 2022, the Company and Medison Pharma Ltd. ("Medison") amended and restated their exclusive distribution agreement for KIMMTRAK originally entered into in September 2021. Medison is the exclusive distribution partner for KIMMTRAK in Canada, Australia, New Zealand, Israel, Central and Eastern Europe, and following this amendment South and Central America, and the Caribbean.

#### Tebentafusp Phase 2/3 trial in advanced melanoma
The Company is screening patients in its Phase 2/3 clinical trial of tebentafusp in patients with previously treated advanced melanoma. The trial will enroll patients with advanced melanoma, excluding uveal melanoma, who have progressed on an anti-PD1, received prior ipilimumab and, if applicable, received a tyrosine kinase inhibitor (TKI). Patients will be randomized to one of three arms including tebentafusp, as monotherapy or in combination with an anti-PD1, and a control arm. The Phase 2 portion of the trial will include 40 patients per arm and has a dual primary endpoint of overall survival (OS) and circulating tumor DNA (ctDNA) reduction.

#### IMC-F106C targeting PRAME-A02 in multiple solid tumors
The Company's planned global expansion of the clinical trial footprint for PRAME-A02 studies is underway, with additional patients now being recruited into the Phase 1/2 monotherapy and combination expansion arms in order to characterize the breadth of clinical activity across multiple tumor types. Initial Phase 1 data with IMC-F106C targeting PRAME (PRAME-A02) was presented at the European Society for Medical Oncology (ESMO) Congress 2022, and the Company initiated four expansion arms—cutaneous melanoma, ovarian, non-small cell lung cancer (NSCLC), and endometrial cancers. The combinations with standards-of-care (checkpoint inhibitors, chemotherapy, and tebentafusp) will position the Company to explore IMC-F106C in earlier lines of treatment. The Company expects to report data from the monotherapy and combination arms by the first half of 2024.

#### Expansion of PRAME franchise: IMC-T119C (PRAME-A24) & IMC-P115C (PRAME-A02 HLE)
In January 2023, the Company revealed the addition of two new PRAME ImmTAC candidates for solid tumors to the pipeline. Building on enthusiasm for IMC-F106C targeting PRAME HLA-A02, the Company has expanded its franchise targeting PRAME.

IMC-F106C is an ImmTAC targeting PRAME for patients with HLA-A02, which is expressed in approximately 40% of Western populations (United States, Canada, EU). In order to expand the potential of TCR therapy targeting PRAME, the Company is developing IMC-T119C, a first-in-class ImmTAC product candidate targeting a PRAME peptide presented by HLA-A24. HLA-24 is an HLA-type that is estimated to be present in 60% of people in Japan and 15-20% in Western populations.

In addition, the Company is developing IMC-P115C, a half-life extended (HLE) ImmTAC product candidate targeting PRAME-A02, with the aim of improving patient convenience. IMC-P115C targets the same PRAME-A02 peptide and uses the same CD3 end and TCR specificity as IMC-F106C.

The Company plans to submit investigational new drug applications (INDs) for these two ImmTAC candidates in 2024.

------

#### First-in-class ImmTAC candidate – IMC-R117C (PIWIL1)
In January 2023, the Company announced an ImmTAC targeting a novel protein for colorectal and other gastrointestinal cancers. The Company has leveraged its proprietary peptidomic database to validate a novel target, PIWIL1. 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 gastro-esophageal, and pancreatic cancer. PIWIL1 is also reported to be a negative prognostic marker. The Company believes IMC-R117C is the first PIWIL1 targeted immunotherapy and plans to submit an IND in the fourth quarter of 2023.

#### IMC-C103C targeting MAGE-A4
In December 2022, the Company presented Phase 1 data for IMC-C103C in a poster presentation at the ESMO Immuno-Oncology 2022 Congress.

In February 2023, Genentech accepted Immunocore's proposal to cease co-funding the development of MAGE-A4 HLA-A02 targeted programs, except for Immunocore's equal share of the wind-down costs of the IMC-C103C Phase 1 clinical trial. The clinical trial with IMC-C103C is nearing completion and Immunocore does not plan to enroll additional patients. Immunocore is eligible to receive development and commercial milestone payments plus royalties from Genentech on any sales of MAGE-A4 HLA-A02 targeted products arising under the Genentech agreement.

#### ImmTAV<sup>®</sup> clinical programs
In February 2023, the Company presented initial safety and pharmacodynamic activity data with IMC-C113V, the first soluble TCR therapy for people living with Human Immunodeficiency Virus (HIV), at the Conference on Retroviruses and Opportunistic Infections (CROI) 2023. IMC-M113V is an immunotherapeutic approach designed to specifically eliminate CD4+ cells that are persistently infected with HIV ('reservoirs'). All doses (1.6 mcg, 5 mcg, and 15 mcg) of IMC-M113V were well tolerated and not associated with cytokine release syndrome or neurotoxicity of any grade. There were no serious adverse events, nor significant changes in hematology or chemistry. Plasma viral load remained suppressed throughout dosing and follow-up. In addition, transient, dose-dependent increases in serum IL6 occurred 8-24 hours post-infusion. Five out of the ten participants who received the 15-mcg dose showed a >4-fold rise in IL6, which had been prespecified as indicative of pharmacodynamic activity based on prior experience from clinical trials with KIMMTRAK.

The Company has started enrolling people living with HIV in the multiple ascending dose (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 (ART), or functional cure. The MAD trial will enroll up to 28 participants.

In the second quarter of 2022, the Company presented data from the first three patients in the first-in-human clinical trial of IMC-I109V for chronic hepatitis B at the EASL International Liver Congress. In this first cohort, the three patients received a single dose of 0.8 mcg, based on the minimum anticipated biological effect level (MABEL). The dose in this initial cohort was well tolerated and was not associated with adverse events and resulted in a transient, small decrease in serum HBsAg with concomitant minor increase in alanine transaminase (ALT). The Company is enrolling patients in the single ascending dose portion of the trial.

------

#### Corporate and financial updates
In December 2022, the Company entered into an agreement with Gadeta B.V., to develop the first gamma delta (γδ) TCR ImmTAC for solid tumors, including colorectal cancer. Immunocore will collaborate with Gadeta on '201 γδ-TCR target discovery and has an option to develop ImmTAC therapies derived from the '201 TCR as part of the research collaboration.

#### Financial Results
Basic and diluted loss per share was £0.54 (or $0.63) and £0.90 (or $1.09) for the quarter and year ended December 31, 2022, respectively, as compared to a basic and diluted loss per share of £0.90 and £3.10, respectively, for the same periods in 2021. Total operating loss for the quarter and year ended December 31, 2022, was £22.3 million (or $27.0 million) and £39.6 million (or $47.8 million), respectively, as compared to £37.8 million and £135.2 million respectively for the same periods in 2021.

For the fourth quarter and year ended December 31, 2022, we generated total revenue from the sale of therapies of £42.3 million ($51.1 million) and £116.8 million ($141.1 million), respectively, due to the sale of KIMMTRAK and tebentafusp, of which £32.1 million ($38.8 million) and £80.4 million ($97.2 million), respectively was in the United States, £10.1 million ($12.2 million) and £35.5 million ($42.9 million), respectively, was in Europe, and £0.1 million ($0.1 million) and £0.9 million ($1.1 million), respectively, was in the rest of the world. We received marketing approval for KIMMTRAK in the United States, Europe and other territories in the year ended December 31, 2022, and did not have marketing approval for, and thus no product revenue from, KIMMTRAK in the year ended December 31, 2021.

For the fourth quarter and year ended December 31, 2022, our research and development ("R&D") expenses were £27.1 ($32.8 million) and £89.2 million (or $107.9 million), respectively as compared to £20.1 million and £73.2 million for the quarter and year ended December 31, 2021. These increases were due to increased expenses in connection with our IMC-F106C program and increased headcount and laboratory costs. The Company expects R&D expenses to increase in future periods as the Company advances its trials and further develops clinical and preclinical pipeline candidates.

For the quarter and year ended December 31, 2022, our selling and administrative expenses were £43.1 million ($52.1 million) and £93.7 million (or $113.2 million), respectively, compared to £24.4 million and £88.4 million for the quarter and year ended December 31, 2021. These increases were related to higher selling and distribution costs following regulatory approval of KIMMTRAK and an increase in headcount costs (excluding share-based payment charges, which reduced in 2022). Our administrative expenses also increased in the fourth quarter of 2022 due to approximately $15 million of non-cash foreign exchange losses, primarily on U.S. dollar balances.

Cash and cash equivalents were £332.5 million (or $401.6 million) as of December 31, 2022, as compared to £237.9 million (or $321.1 million) as of December 31, 2021. We expect that our existing cash, along with anticipated revenue from KIMMTRAK, will be sufficient to fund our planned operating expenses, financial commitments and other cash requirements into 2026.

*We maintain our books and records in pounds sterling. For the convenience of the reader, we have translated pound sterling amounts as of and for the period ended December 31, 2022 into U.S. dollars at a rate of £1.00 to $1.2077.*

#### About KIMMTRAK<sup>®</sup>
KIMMTRAK is a novel bispecific protein comprised of a soluble T cell receptor fused to an anti-CD3 immune-effector function. KIMMTRAK specifically targets gp100, a lineage antigen expressed in melanocytes and melanoma. This is the first molecule developed using Immunocore's ImmTAC technology platform designed to redirect and activate T cells to recognize and kill tumor cells. KIMMTRAK has been approved for the treatment of HLA-A\*02:01-positive adult patients with unresectable or metastatic uveal melanoma in the United States, European Union, Canada, Australia, and the United Kingdom.

#### About Phase 3 IMCgp100-202 Trial
IMCgp100-202 (NCT03070392) is a randomized pivotal trial that evaluated overall survival (OS) of KIMMTRAK compared to investigator's choice (either pembrolizumab, ipilimumab, or dacarbazine) in HLA-A\*02:01-positive adult patients with previously untreated mUM. KIMMTRAK demonstrated an unprecedented OS benefit with a Hazard Ratio (HR) in the intent-to-treat population favoring KIMMTRAK, HR=0.51 (95% CI: 0.37, 0.71); p< 0.0001, over investigator's choice (82% pembrolizumab; 13% ipilimumab; 6% dacarbazine).

#### IMPORTANT SAFETY INFORMATION
**Cytokine Release Syndrome (CRS), which may be serious or life-threatening, occurred in patients receiving KIMMTRAK. Monitor for at least 16 hours following first three infusions and then as clinically indicated.** Manifestations of CRS may include fever, hypotension, hypoxia, chills, nausea, vomiting, rash, elevated transaminases, fatigue, and headache*.* CRS occurred in 89% of patients who received KIMMTRAK with 0.8% being grade 3 or 4. Ensure immediate access to medications and resuscitative equipment to manage CRS. Ensure patients are euvolemic prior to initiating the infusions. Closely monitor patients for signs or symptoms of CRS following infusions of KIMMTRAK. Monitor fluid status, vital signs, and oxygenation level and provide appropriate therapy. Withhold or discontinue KIMMTRAK depending on persistence and severity of CRS.

#### Skin Reactions
Skin reactions, including rash, pruritus, and cutaneous edema occurred in 91% of patients treated with KIMMTRAK. Monitor patients for skin reactions. If skin reactions occur, treat with antihistamine and topical or systemic steroids based on persistence and severity of symptoms. Withhold or permanently discontinue KIMMTRAK depending on the severity of skin reactions.

------

#### Elevated Liver Enzymes
Elevations in liver enzymes occurred in 65% of patients treated with KIMMTRAK. Monitor alanine aminotransferase (ALT), aspartate aminotransferase (AST), and total blood bilirubin prior to the start of and during treatment with KIMMTRAK. Withhold KIMMTRAK according to severity.

#### Embryo-Fetal Toxicity
KIMMTRAK may cause fetal harm. Advise pregnant patients of potential risk to the fetus and patients of reproductive potential to use effective contraception during treatment with KIMMTRAK and 1 week after the last dose.

The most common adverse reactions (≥30%) in patients who received KIMMTRAK were cytokine release syndrome, rash, pyrexia, pruritus, fatigue, nausea, chills, abdominal pain, edema, hypotension, dry skin, headache, and vomiting.
