NOTES TO THE UNAUDITED INTERIM CONDENSED

CONSOLIDATED FINANCIAL STATEMENTS

1. CORPORATE INFORMATION

Legend Biotech Corporation, (the "Company"), was incorporated on May 27, 2015 as an exempted company in the Cayman Islands with limited liability under the Companies Act (As Revised) of the Cayman Islands. The registered office address of the Company is PO Box 10240, Harbour Place, 103 South Church Street, George Town, Grant Cayman KY1-1002, Cayman Islands.

Legend Biotech Corporation is an investment holding company. The Company’s subsidiaries are principally engaged in the discovery, and development, manufacturing and commercialization of novel cell therapies for oncology and other indications.

2.1. BASIS OF PREPARATION

The unaudited interim condensed consolidated financial statements of Legend and its subsidiaries (collectively referred to as the “Company”) for the three months ended March 31, 2024 have been prepared in accordance with International Accounting Standard (“IAS”) 34 Interim Financial Reporting (“IAS34”) issued by the International Accounting Standards Board (the “IASB”).

The accounting policies and basis of preparation adopted in the preparation of these unaudited interim condensed consolidated financial statements are consistent with those followed in the preparation of the Company financial statements for the year ended December 31, 2023. The Company has not early adopted any other standards, interpretation or amendments that have been issued but are not yet effective.

In the opinion of the Company’s management, the accompanying unaudited interim condensed consolidated financial statements contain all normal recurring adjustments necessary to present fairly the financial position, operating results and cash flows of the Company for each of the periods presented. The results of operations for the three months ended March 31, 2024 are not necessarily indicative of results to be expected for any other interim periods or for the year ended December 31, 2023. The condensed consolidated statement of financial position as of December 31, 2023 was derived from the audited consolidated financial statements at that date but does not include all of the disclosures required by the IASB for annual financial statements. These unaudited interim condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements for the year ended December 31, 2023.

2.2. NEW STANDARDS, INTERPRETATIONS AND AMENDMENTS ADOPTED BY THE COMPANY

There were no new International Financial Reporting Standards (“IFRS”), amendments or interpretations issued by the IASB that became effective in the three months ended March 31, 2024 that had a material impact on the Company's unaudited interim condensed consolidated financial statements.

3. REVENUE, OTHER INCOME AND GAINS

An analysis of revenue is as follows:


	Three months ended March 31,
	2024	2023
	US$’000 (Unaudited)	US$’000 (Unaudited)
Revenue

Novartis License Agreement

On November 10, 2023, Legend Biotech, through its wholly owned subsidiary, Legend Biotech Ireland Limited, entered into an exclusive, global license agreement with Novartis Pharma AG (the "Novartis License Agreement"). The Company granted Novartis the worldwide rights to develop, manufacture and commercialize LB2102 and other potential chimeric antigen receptor T-cell (CAR-T) therapies selectively targeting Delta-like Ligand 3 (DLL3). The Novartis License Agreement was effective on December 28, 2023, with a $100 million receivable initially recorded, representing the Novartis upfront payment which was then received on January 3rd, 2024. Novartis has also agreed to pay up to $1.01 billion in milestone payments upon achievement of specified clinical, regulatory and commercial milestones, as well as tiered royalties on net sales. We determined that any milestone payments will be recognized upon occurrence as they were determined to relate predominately to the license granted and therefore have been excluded from the transaction price. We determined that any sales-based royalties will be recognized when the related sales occur as they were determined to relate predominately to the license granted and therefore have been excluded from the transaction price. Under the Novartis License Agreement, Legend Biotech will conduct the Legend Phase 1 clinical trial for LB2102 in the U.S. Novartis will conduct all other development, manufacture and commercialization for the licensed product(s).

The following table shows the deferred revenue which is included in contract liabilities for the periods presented:

Total	5,475	5,113

5. LOSS PER SHARE ATTRIBUTABLE TO ORDINARY EQUITY HOLDERS OF THE PARENT

The calculation of the basic loss per share amount is based on the loss for the period attributable to ordinary equity holders of Legend Biotech Corporation, and the weighted average number of ordinary shares of 364,010,429 and 330,497,072 in issue during the three months ended March 31, 2024 and 2023, respectively.

The calculation of the diluted earnings per share amount is based on the loss for the period attributable to ordinary equity holders of the parent. The weighted average number of ordinary shares used in the calculation is the number of ordinary shares in issue during the period, as used in the basic earnings per share calculation, and the weighted average number of ordinary shares assumed to have been issued at no consideration on the deemed exercise of all dilutive potential ordinary shares into ordinary shares.

No adjustment has been made to the basic loss per share amounts presented for the three months ended March 31, 2024 and 2023, as the impact of the outstanding share options and RSU had an anti-dilutive effect on the basic loss per share amounts presented.

The calculations of basic and diluted loss per share are based on:


	Three months ended March 31,
	2024	2023
	US$’000 (Unaudited)	US$’000 (Unaudited)

The Company has leases for office, research laboratory and manufacturing facilities, equipment, vehicles and land.

Lump sum payments were made upfront to acquire the leasehold land from the owners with lease periods of 50 years, and no ongoing payments will be made under the terms of these leasehold land. Leases with terms of 12 months or less are expensed as incurred, Collaboration assets represent the Company’s share of assets leased to the collaboration from Janssen, which purchased the assets on behalf of the collaboration, in connection with the Janssen Agreement. Collaboration assets under construction that will be leased to the collaboration from Janssen when placed into service are classified as collaboration prepaid leases on the consolidated financial statements.

Pursuant to the license and collaboration agreement entered into with a collaborator, the Company is entitled to receive funding advances from the collaborator when certain operational conditions are met. As a result, the Company took an initial funding advance with principal amounting to $17.3 million on June 18, 2021, a second funding advance with principal amounting to $53.1 million on September 17, 2021, a third funding advance with principal amounting to $49.3 million on December 17, 2021, a forth funding advance with principal amounting to $5.3 million on March 18, 2022, a fifth funding advance with principal amounting to $60.9 million on June 17, 2022, a sixth funding advance with principal amounting to $60.5 million on September 16, 2022, and a seventh funding advance with principal amounting to $3.6 million on December 16, 2022, by reducing the same amount of other payables due to the collaborator, respectively (collectively, the “Funding Advances”).

These Funding Advances are accounted for as interest-bearing borrowings funded by the collaborator, constituted by a principal amounting to $250.0 million and applicable interests accrued amounting to $36.4 million upon such principal. The respective interest rate of each borrowing has transitioned from London Interbank Offered Rate (LIBOR) to Secured Overnight Financing Rate (SOFR) in accordance with the LIBOR ACT . Thus, outstanding advances accrue interest at 12 month CME term SOFR plus LIBOR/SOFR adjustment (12 month) plus a margin of 2.5%. For each of the seven batches of funding advances, interest started to accrue from June 18, 2021, September 17, 2021, December 17, 2021, March 18, 2022, June 17, 2022, September 16, 2022, and December 16, 2022, respectively.

Pursuant to the terms of the license and collaboration agreement, the collaborator may recoup the aggregate amount of Funding Advances, together with interest thereon, from Company’s share of pre-tax profits from the first profitable year of the collaboration program and, subject to some limitations, from milestone payments due to the Company under the Janssen Agreement. The Company’s management estimated the loan will not be recouped by the collaborator within one year, nor does the Company expect to repay the funding advances within one year, and thus the loan was classified as a long-term liability.

14. FAIR VALUE AND FAIR VALUE HIERARCHY OF FINANCIAL INSTRUMENTS

Management has assessed that the fair values of cash and cash equivalents, pledged deposits, time deposits, financial assets included in prepayments, other receivables and other assets, trade receivables, trade payables and financial liabilities included in other payables and accruals approximate to their carrying amounts largely due to the short-term maturities of these instruments.

The Company’s finance department, headed by the Corporate Controller, is responsible for determining the policies and procedures for the fair value measurement of financial instruments. The finance department reports directly to the Corporate Controller. At March 31, 2024, the finance department analyzed the movements in the values of financial instruments and determined the major inputs applied in the valuation. The valuation was reviewed and approved by the finance manager. The valuation process and results are discussed with the directors once a year for annual financial reporting.

The fair values of the financial assets and liabilities are included at the amount at which the instrument could be exchanged in a current transaction between willing parties, other than in a forced or liquidation sale.

The following table illustrates the fair value measurement hierarchy of the Company’s financial instruments:

Overview

We are primarily a global, clinical-stage biopharmaceutical company engaged in the discovery, development, manufacturing and commercialization of novel cell therapies for oncology and other indications. Our team of approximately 2,000 employees in the United States, China and Europe, our differentiated technology, global development and manufacturing strategy and expertise provide us with the ability to generate, test and manufacture next-generation cell therapies targeting indications with high unmet needs. Our lead product candidate, ciltacabtagene autoleucel, ("cilta-cel") (referred to as LCAR- B38M for purposes of our LEGEND-2 trial), is a CAR-T cell therapy we are jointly developing with our strategic partner, Janssen, for the treatment of multiple myeloma (“MM”). Clinical trial results achieved to date demonstrate that cilta-cel has the potential to deliver deep and durable anti-tumor responses in relapsed and refractory multiple myeloma (“RRMM”) patients with a manageable safety profile.

On February 28, 2022, cilta-cel was approved by the U.S. Food and Drug Administration (the “FDA”) under the trademark CARVYKTI for the treatment of adults with RRMM who have received four or more prior lines of therapy, including a proteasome inhibitor, an immunomodulatory agent, and an anti-CD38 monoclonal antibody. CARVYKTI was our first product approved by a health authority.

Recent Business Developments

•CARVYKTI® (ciltacabtagene autoleucel; cilta-cel) net trade sales of approximately $157 million.

•EC and US FDA approved CARVYKTI® label expansion in earlier lines of treatment for adult patients with relapsed and lenalidomide-refractory multiple myeloma.

•Legend and Johnson & Johnson enter into Master Manufacturing and Commercial Supply Services Agreement with Novartis Pharmaceuticals Corporation.

•On April 5, Legend Biotech earned a milestone payment of $45 million in connection with FDA’s approval of CARVYKTI's label expansion to treat 2L+ MM, in accordance with the Janssen Agreement.

•Cash and cash equivalents, deposits and short-terms investments of $1.3 billion, as of March 31, 2024, which Legend believes will provide financial runway into 2026, when Legend Biotech anticipates achieving an operating profit.

Global Economic Conditions

Changes in economic conditions, supply chain constraints, logistics challenges, labor shortages, the Russia-Ukraine war, the conflict between Israel and Hamas and steps taken by governments and central banks, have led to higher inflation, which has led to an increase in costs and has caused changes in fiscal and monetary policy, including increased interest rates. Our product manufacturing in both the U.S. and China has continued. Currently we have not experienced any material impact to our material supply chain or as a result of inflation and rising interest rates. Increased quantities of certain raw materials and consumables have been stocked as an appropriate safety measure. We believe we have established robust sourcing strategies for all necessary materials and do not expect any significant impact.

Although we do not believe that these macroeconomic conditions have had a material impact on our financial position or results of operations to date, if these changes in economic conditions continue or if they increase in severity, it could result in further economic uncertainty and volatility in the capital markets in the near term, and could negatively affect our operations.

Revenue

License Revenue

License revenue for the three months ended March 31, 2024, was $12.2 million and consisted of the recognition of deferred revenue in connection with the global license agreement with Novartis Pharmaceuticals Corporation to develop, manufacture, and commercialize LB2102 and other potential CAR-T therapies selectively targeting DLL3. The Company did not recognize any license revenue for the three months ended March 31, 2023.

Collaboration Revenue

Collaboration revenue for the three months ended March 31, 2024, was $78.5 million, compared to $36.3 million for the three months ended March 31, 2023. This increase of $42.2 million was due to an increase in revenue generated from sales of CARVYKTI in connection with the Janssen Agreement.

Other Revenue

Other revenue for the three months ended March 31, 2024, was $3.3 million, compared to $0.1 million for the three months ended March 31, 2023. This increase of $3.2 million was driven by materials provided to Novartis in connection with the Novartis License Agreement.

Operating Expenses

Collaboration cost of revenue

Collaboration cost of revenue for the three months ended March 31, 2024, was $49.1 million compared to $35.6 million for the three months ended March 31, 2023. The increase of $13.5 million is primarily due to an increase of our share of cost of sales incurred in connection with CARVYKTI sales under the Janssen Agreement.

Cost of license and other revenue

Cost of license and other revenue for the three months ended March 31, 2024, was $5.6 million and consisted of costs in connection with the global license agreement with Novartis Pharma AG to develop, manufacture, and commercialize LB2102 and other potential CAR-T therapies selectively targeting DLL3. The Company did not incur any cost of license and other revenue for the three months ended March 31, 2023.

Research and Development Expenses

Research and development expenses for the three months ended March 31, 2024, were $101.0 million compared to $84.9 million for the three months ended March 31, 2023. This increase of $16.1 million was primarily due to continuous research and development activities in cilta-cel, including start up costs for clinical production in Belgium and continued investment in our solid tumor programs.

Administrative Expenses

Administrative expenses for the three months ended March 31, 2024, were $31.9 million compared to $22.2 million for the three months ended March 31, 2023. The increase of $9.7 million was due to our expansion of administrative functions and infrastructure to increase manufacturing capacity.

Selling and Distribution Expenses

Selling and distribution expenses for the three months ended March 31, 2024, were $24.2 million compared to $18.0 million for the three months ended March 31, 2023. This increase of $6.2 million was due to costs associated with commercial activities for cilta-cel, including the expansion of the sales force and second line indication launch preparation.

Other Income and Gains

Other income and gains for the three months ended March 31, 2024, were $64.1 million compared to $8.2 million for the three months ended March 31, 2023. The increase of $55.9 million was primarily due to increases in interest income and unrealized foreign currency exchange gains in 2024.

Other Expenses

Other expenses for the three months ended March 31, 2024, were $0.5 million compared to $10.7 million for the three months ended March 31, 2023. The decrease was primarily due to unrealized foreign currency exchange losses in 2023 and an unrealized foreign currency exchange gain in 2024.

Finance Costs

Finance costs for the three months ended March 31, 2024, were $5.5 million compared to $5.1 million for the three months ended March 31, 2023. The increase was primarily due to interest on advance funding, which is interest-bearing borrowings funded by Janssen under the Janssen Agreement and constituted by principal and applicable interests upon such principal.

Fair Value Gain of Warrant Liability

There was no fair value (loss)/gain of warrant liability for the three months ended March 31, 2024, compared to a fair value gain of $20.0 million for the three months ended March 31, 2023. There is no gain or loss on the fair value of the warrants in 2024 because the warrants were exercised on May 11, 2023.

Loss for the Period

For the three months ended March 31, 2024, net loss was $59.8 million, or $0.16 per share, compared to a net loss of $112.1 million, or $0.34 per share, for the three months ended March 31, 2023.

Income Tax Expense

Income tax expense for the three months ended March 31, 2024, was $0.01 million, compared to $0.1 million for the three months ended March 31, 2023.

Liquidity and Capital Resources

Sources of Liquidity

Since our inception, we have incurred significant operating losses. We expect to incur operating losses over the next several years as we continue the commercialization of CARVYKTI and advance the preclinical and clinical development of our research programs and product candidates. Additionally, over the next several years, we expect to incur significant capital expenditures associated with ramping up our manufacturing capabilities for our commercial product. Based on our cash and cash equivalents, deposits, and investments of $1.3 billion, as of March 31, 2024, we believe that we will be able to fund our planned operations and capital expenditure requirements into 2026, when we expect to begin to achieve an operating profit. We may, in the future, pursue additional cash resources through a combination of equity or debt financings, collaborations, licensing arrangements or other sources to maintain a certain level of working capital.

With the exception of our first product, CARVYKTI, which was initially approved by the FDA on February 28, 2022, we do not currently have any approved products and we have not generated any revenue from product sales for other products. From inception through March 31, 2024, we have funded our operations primarily with approximately:

•$3.9 million in capital contributions from Genscript;

•$160.5 million in gross proceeds from the sale of our Series A preference shares;

•$685.0 million in upfront and milestone payments from Janssen under our collaboration and license agreement;

•$450.1 million in net proceeds from our U.S. initial public offering and an additional $12 million from a concurrent private placement with Genscript;

•$300.0 million in net proceeds from our private placement to an investor and related warrant issuance in May 2021;

•$323.4 million in net proceeds from our public offering of ADSs that closed in December 2021;

•$250.0 million in advances from Janssen under our the Janssen Agreement;

•$377.6 million in net proceeds from our public offering of ADSs that closed in July 2022;

•$234.4 million in net proceeds from private placements to certain investors in May and June 2023;

•$349.3 million in net proceeds from our public offering of ADS that closed in May 2023;

•$199.7 million in net proceeds from the exercise in full of a warrant held by one of our investors;

As of March 31, 2024, we had approximately $0.9 billion in cash and cash equivalents, approximately $258.7 million of time deposits, approximately $150.4 million of financial assets measured at fair value through profit or loss and accumulated losses of $1.5 billion.

Certain of our subsidiaries, including those registered as wholly foreign-owned enterprises in the People's Republic of China (the "PRC"), are required to set aside at least 10.0% of their after-tax profits to their general reserves until such reserves reach 50.0% of their registered capital. Under PRC regulations, foreign-invested enterprises may pay dividends only out of their accumulated profit, if any, as determined in accordance with PRC accounting standards and regulations. A PRC company is not permitted to distribute any profits until any losses from prior fiscal years have been offset. Profits retained from prior fiscal years may be distributed together with distributable profits from the current fiscal year. Although we do not currently require any such dividends from our PRC subsidiaries to fund our operations, should we require additional sources of liquidity in the future, such restrictions may have a material adverse effect on our liquidity and capital resources. For more information, see “Item 4.B-Business Overview - Government Regulation - PRC Regulation - Other PRC National- and Provincial-Level Laws and Regulations - Regulations Relating to Dividend Distributions.”

Our capital expenditures for the three months ended March 31, 2024 and 2023 amounted to $19.0 million and $33.4 million, respectively. These expenditures primarily consisted of property, plant, equipment and collaboration prepaid leases.

Funding Requirements

We expect our expenses to increase in connection with our ongoing activities, particularly as we continue the research and development of, continue or initiate clinical trials of, and seek marketing approval for, our product candidates. In addition, we expect to continue to incur significant commercialization expenses for CARVYKTI related to program sales, marketing, manufacturing and distribution to the extent that such sales, marketing, manufacturing and distribution are not the responsibility of potential collaborators. For example, in addition to investing in our own facilities, we have supplemented our manufacturing capabilities and infrastructure by entering into agreements with CMOs. Furthermore, we expect to incur additional costs associated with operating as a public company. Accordingly, we will need to obtain substantial additional funding in connection with our continuing operations. If we are unable to raise capital when needed or on attractive terms, we would be forced to delay, reduce or eliminate our research and development programs or future commercialization efforts.

Although consequences of the macroeconomic conditions, including global conflicts and inflation, and resulting economic uncertainty could adversely affect our liquidity and capital resources in the future, and cash requirements may fluctuate based on the timing and extent of many factors such as those discussed below, we currently expect our existing cash and cash equivalents will enable us to fund our operating expenses and capital expenditure requirements for at least the next 12 months. Our future capital requirements will depend on many factors, including:

•the scope, progress, results and costs of product discovery, preclinical studies and clinical trials;

•the scope, prioritization and number of our research and development programs;

•the costs, timing and outcome of regulatory review of our product candidates;

•our ability to establish and maintain collaborations on favorable terms, if at all;

•the achievement of milestones or occurrence of other developments that trigger payments under the Janssen Agreement and any other collaboration agreements we enter into;

•the extent to which we are obligated to reimburse, or entitled to reimbursement of, clinical trial costs under collaboration agreements, if any;

•the costs of preparing, filing and prosecuting patent applications, maintaining and enforcing our intellectual property rights and defending intellectual property-related claims;

•the extent to which we acquire or in-license other product candidates and technologies;

•the costs of securing manufacturing arrangements for commercial production; and

•the costs of establishing or contracting for sales and marketing capabilities if we obtain regulatory approvals to market our product candidates.

In addition to cilta-cel, we have a broad portfolio of earlier-stage product candidates. Identifying potential product candidates and conducting preclinical studies and clinical trials is a time- consuming, expensive and uncertain process that takes many years to complete, and we may never generate the necessary data or results required to obtain marketing approval and achieve product sales for such product candidates. In addition, our product candidates, if approved, may not achieve commercial success. Our commercial revenues, if any, will be derived from sales of product candidates that we do not expect to be commercially available for many years, if at all. Accordingly, we will need to continue to rely on additional financing to achieve our business objectives. Adequate additional financing may not be available to us on acceptable terms, or at all.

Until such time, if ever, as we can generate substantial product revenues, we expect to finance our cash needs through a combination of equity offerings, debt financings, collaborations, strategic alliances and licensing arrangements. To the extent that we raise additional capital through the sale of equity or convertible debt securities, holders of our ADSs will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect the rights of our shareholders. Debt financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends.

If we raise funds through additional collaborations, strategic alliances or licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs or product candidates or to grant licenses on terms that may not be favorable to us. If we are unable to raise additional funds through equity or debt financings when needed, we may be required to delay, limit, reduce or terminate our product development or future commercialization efforts or grant rights to develop and market that we would otherwise prefer to develop and market ourselves.

Under the Janssen Agreement, until such time as our collaboration experiences its first profitable year, we are entitled to receive advances from Janssen if the collaboration’s estimated working capital for any year falls below $50 million. In such event, Janssen provides advances to us in an amount equal to the excess of $50 million over the collaboration’s working capital for the year. The total amount of such advances in any calendar year may not exceed $125 million and the total amount of such advances outstanding at any time may not exceed $250 million. The interest rate pursuant to the Janssen Agreement has transitioned in accordance with the LIBOR Act. Thus, outstanding advances accrue interest at 12 month CME term Secured Overnight Financing Rate (“SOFR”) plus LIBOR/SOFR adjustment (12 month) plus a margin of 2.5%. Janssen has the right to recoup such advances and interest from our share of the collaboration’s pre-tax profits and, subject to some limitations, from milestone payments due to us under the Janssen Agreement. We are not otherwise obligated to repay the advances or interest, except in connection with our change in control or a termination of the Janssen Agreement by Janssen due to our material breach of the agreement. We may at any time in our discretion voluntarily pre-pay any portion of the then outstanding advances or associated interest. As of March 31, 2024, the aggregate outstanding principal amount of such advances and interest were approximately $250.0 million and $36.4 million, respectively.

Quantitative and Qualitative Disclosures About Market Risk

Our cash is held in readily available operating accounts and short to medium term deposits and securities. These securities are principal secured and not adversely impacted by interest rate fluctuations. As a result, a change in market interest rates would not have any significant impact on our cash balance.

The interest rate pursuant to our collaboration and license agreement with Janssen, has transitioned in accordance with the LIBOR Act. Thus, outstanding advances accrue interest at 12 month CME term SOFR plus LIBOR/SOFR adjustment (12 month) plus a margin of 2.5%. Accordingly, changes in SOFR could result in fluctuations in our cash flow. For example, based on the $250.0 million aggregate principal amount of advances outstanding from Janssen as of March 31, 2024, a 0.5% (fifty basis point) per annum increase in SOFR would result in an additional $1.3 million per year in interest payable by the Company.

Inflation generally affects us by increasing our cost of labor and clinical trial costs. We do not believe that inflation had a material effect on our business, financial condition or results of operations during the three months ended March 31, 2024 and 2023.

We also do not believe that we are exposed to any material foreign currency exchange rate risk.

SOMERSET, N.J.—May 13, 2024— Legend Biotech Corporation (NASDAQ: LEGN) (Legend Biotech), a global leader in cell therapy, today reported its first quarter 2024 unaudited financial results and key corporate highlights.

“Legend made great progress in the first quarter, culminating in our exciting announcements in recent weeks. We received label expansions for CARVYKTI in the U.S., Europe, and Brazil that have changed the treatment paradigm for multiple myeloma and will enable more patients to receive our transformative therapy earlier in the course of their disease,” said Ying Huang, Ph.D., Chief Executive Officer of Legend Biotech. “With more patients needing access to CARVYKTI, we have increased our manufacturing capacity and have scaled up our operations to reach our goal of 10,000 annual doses by the end of 2025. The expansion of our partnership with Novartis demonstrates our commitment to ensuring every patient who needs CARVYKTI can access it.”

Regulatory Updates

•The U.S. Food and Drug Administration (FDA) approved CARVYKTI® for the treatment of adult patients with relapsed or refractory multiple myeloma who have received at least one prior line of therapy including a proteasome inhibitor (PI) and an immunomodulatory agent (IMiD) and are refractory to lenalidomide following the Oncologic Drug Advisory Committee’s unanimous (11 to 0) vote recommending the approval of CARVYKTI.

•The European Commission (EC) granted approval for the label expansion of CARVYKTI® for the treatment of adult patients with relapsed and refractory multiple myeloma who have received at least one prior therapy, including an immunomodulatory agent and a proteasome inhibitor, have demonstrated disease progression on the last therapy, and are refractory to lenalidomide.

•The Brazilian Health Regulatory Agency, ANVISA (Agência Nacional de Vigilância Sanitária), approved CARVYKTI® for the treatment of adult patients with multiple myeloma, who previously received a proteasome inhibitor and are refractory to lenalidomide, as well as adult patients with relapsed or refractory multiple myeloma, who previously received a proteasome inhibitor, an immunomodulatory agent and anti-CD38 antibody.

Key Business Developments

•Legend and Johnson & Johnson* entered into a Master Manufacturing and Supply Services Agreement with Novartis Pharmaceuticals Corporation to supplement our existing manufacturing capabilities and increase commercial supply of CARVYKTI®

First Quarter 2024 Financial Results

•License Revenue: License revenue was $12.2 million for the first quarter of 2024 and consisted of the recognition of deferred revenue in connection with the global license agreement with Novartis Pharma AG to develop, manufacture, and commercialize LB2102 and other potential CAR-T therapies selectively targeting DLL3. Legend did not recognize any license revenue for the first quarter of 2023.

•Collaboration Revenue: Collaboration revenue was $78.5 million for the first quarter of 2024 compared to $36.3 million for the first quarter of 2023. The increase was primarily due to an increase in revenue generated from sales of CARVYKTI® in connection with the Janssen Agreement.

•Collaboration Cost of Revenue: Collaboration cost of revenue was $49.1 million for the first quarter of 2024 compared to $35.6 million for the first quarter of 2023. The increase was primarily due to Legend Biotech’s share of the cost of sales in connection with CARVYKTI® sales under the Janssen Agreement.

•Cost of License and Other Revenue: Cost of license and other revenue for the three months ended March 31, 2024 was $5.6 million and consisted of costs in connection with the global license agreement with Novartis Pharma AG to develop, manufacture, and commercialize LB2102 and other potential CAR-T therapies selectively targeting DLL3. The Company did not incur any cost of license and other revenue for the three months ended March 31, 2023.

•Research and Development Expenses: Research and development expenses were $101.0 million for the first quarter of 2024 compared to $84.9 million for the first quarter of 2023. The increase was primarily driven by continuous research and development activities in cilta-cel, including start up costs for clinical production in Belgium and continued investment in Legend’s solid tumor programs.

•Administrative Expenses: Administrative expenses were $31.9 million for the first quarter of 2024 compared to $22.2 million for the first quarter of 2023. The increase was primarily due to the expansion of administrative functions and infrastructure to increase manufacturing capacity.

•Selling and Distribution Expenses: Selling and distribution expenses were $24.2 million for the first quarter of 2024 compared to $18.0 million for the first quarter of 2023.The increase was primarily driven by costs associated with commercial activities for cilta-cel, including the expansion of the sales force and second line indication launch preparation.

•Net Loss: Net loss was $59.8 million for the first quarter of 2024, compared to a net loss of $112.1 million for the first quarter of 2023.

•Cash Position: Cash and cash equivalents, time deposits, and short-term investments were $1.3 billion as of March 31, 2024.
