Financial Results for First Quarter Ended March 31, 2021
Cash and Cash Equivalents and Time Deposits

As of March 31, 2021, Legend Biotech had approximately $412.3 million of cash and cash equivalents and approximately $50.0 million in time deposits.
Revenue
Revenue for the three months ended March 31, 2021 was $13.7 million compared to $11.5 million for the three months ended March 31, 2020. The increase of $2.2 million was primarily due to revenue recognition of additional milestone payment achieved pursuant to Legend Biotech’s agreement with Janssen. Milestone payments are constrained as a result of the uncertainty of whether the milestone will be achieved, but recognized when the associated milestone is achieved and the uncertainty relieved. In the first quarter of 2021, this resulted in a larger amount of revenue recognized from the contract liabilities. Legend Biotech has not generated any revenue from product sales to date.
Research and Development Expenses
Research and development expenses for the three months ended March 31, 2021 were $71.1 million compared to $48.0 million for the three months ended March 31, 2020. This increase of $23.1 million was primarily due to a higher number of clinical trials with more patients enrolled and a higher number of research and development product candidates.
Administrative Expenses
Administrative expenses for the three months ended March 31, 2021 were $8.7 million compared to $3.4 million for the three months ended March 31, 2020. The increase of $5.3 million was primarily due to Legend Biotech’s expansion of supporting administrative functions to aid continued research and development activities.
Selling and Distribution Expenses
Selling and distribution expenses for the three months ended March 31, 2021 were $13.4 million compared to $6.5 million for the three months ended March 31, 2020. This increase of $6.9 million was primarily due to increased costs associated with commercial preparation activities for cilta-cel.

Other Income and Gains
Other income and gains for the three months ended March 31, 2021 was $0.7 million compared to $2.5 million for the three months ended March 31, 2020. The decrease of $1.8 million was primarily due to lower government grant and interest income received in first quarter of 2021.
Other Expenses
Other expenses for the three months ended March 31, 2021 was $2.0 million compared to $0.05 million for the three months ended March 31, 2020. The increase was primarily due to higher foreign currency exchange loss in first quarter of 2021.
Finance Costs
Finance costs for the three months ended March 31, 2021 was $0.04 million compared to $4.0 million for the three months ended March 31, 2020. The decrease was primarily due to finance costs related to the issuance of convertible redeemable preferred shares in 2020, which were fully converted into ordinary shares upon the completion of Legend Biotech’s initial public offering in June 2020.
Loss for the Period
For the three months ended March 31, 2021, net loss was $80.9 million, or $0.30 per share, compared to a net loss of $44.2 million, or $0.22 per share, for the three months ended March 31, 2020.

A Biologics License Application seeking approval of cilta-cel was submitted to the U.S. FDA and a Marketing Authorization Application was submitted to the European Medicines Agency.

About Clinical Development Program
CARTITUDE-1 (NCT03548207) is a Phase 1b/2, open-label, multicenter study evaluating the safety and efficacy of cilta-cel in adults with relapsed and/or refractory multiple myeloma who have received at least three prior lines of therapy or are double refractory to an immunomodulatory drug (IMiD) and a proteasome inhibitor (PI), received an IMiD, a PI and an anti-CD38 antibody, and documented disease progression within 12 months of starting the most recent therapy.¹The primary objective of the Phase 1b portion of the study was to characterize the safety and confirm the dose of cilta-cel, informed by the first in-human study with LCAR-B38M CAR-T cells (LEGEND-2). The Phase ² portion further evaluated the efficacy of cilta-cel with overall response rate as the primary endpoint.

CARTITUDE-2 (NCT04133636)is a global, multi-cohort Phase ²study evaluating cilta-cel in patients with multiple myeloma in various clinical settings.² This study is being conducted to evaluate the overall minimal residual disease (MRD) negative rate of participants who receive cilta-cel.

CARTITUDE-4 (NCT04181827) is a global, randomized Phase ³ study, evaluating cilta-celin patients with multiple myeloma who have received 1-3 prior lines of therapy including a PI and IMiD and are refractory to lenalidomide.³ The study is being conducted to evaluate the efficacy of cilta-cel compared to standard therapiesincluding daratumumab, pomalidomide and low-dose dexamethasone (DPd) or pomalidomide, bortezomib and low-dose dexamethasone (PVd).
CARTIFAN-1 (NCT03758417) is a Phase 2 confirmatory trial registered with the China Center for Drug Evaluation (CTR20181007) to further evaluate LCAR-B38M CAR-T cells in patients with advanced RRMM.4
