Second Quarter Financial Results

Cash and Cash Equivalents

Cash and cash equivalents were $376.8 million as of June 30, 2022, compared to $466.5 million as of December 31, 2021.

Product Revenue

Product revenue (net) was $17.3 million for the quarter, compared to $3.8 million for the same quarter in 2021. Net revenues are for U.S. sales of ZYNLONTA, which received accelerated approval from the FDA on April 23, 2021.

Cost of product sales

Cost of product sales was $2.3 million for the quarter, compared to $0.1 million for the same quarter in 2021, an increase of $2.1 million associated with $1.9 million of impairment charges primarily related to the manufacturing of antibodies that was not within the Company’s specifications. The specification issues did not, and are not expected to, impact the Company’s ability to supply commercial product. In addition, cost of product sales increased due to a full second quarter of sales activity in 2022 as compared to the same period in 2021 due to the commencement of ZYNLONTA sales in May 2021.

Research and Development (R&D) Expenses

R&D expenses were $48.5 million for the quarter ended June 30, 2022, compared to $39.5 million for the same quarter in 2021. As a result of FDA approval of ZYNLONTA in April 2021, the Company reversed $6.8 million of previously recorded impairment charges during the three months ended June 30, 2021, relating to inventory costs incurred for the manufacture of product prior to FDA approval. In addition, R&D expenses increased due to clinical activities to expand ZYNLONTA’s potential market opportunities in earlier lines of therapy and advance the Company’s portfolio of solid tumor programs.

Selling and Marketing (S&M) Expenses

S&M expenses were $17.7 million for the quarter ended June 30, 2022, as compared to $15.2 million for the same quarter in 2021. The increase in S&M expenses is related to the ongoing launch of ZYNLONTA.

G&A Expenses

G&A expenses were $18.2 million for the quarter ended June 30, 2022, compared to $19.4 million for the same quarter in 2021. G&A expenses decreased primarily due to lower share-based compensation expense.

Net Loss and Adjusted Net Loss

Net loss was $64.4 million, or a net loss of $0.84 per basic and diluted share, for the quarter ended June 30, 2022. This compares to a net loss of $72.6 million, or a net loss of $0.95 per basic and diluted share, for the same quarter in 2021. The decrease in net loss for the quarter ended June 30, 2022, as compared to the same period in 2021, was primarily due to higher product revenue, partially offset by the increase in cost of product sales, R&D and S&M expenses. In addition, net loss decreased for the second quarter of 2022 as a result of income arising from changes in the fair value of derivatives associated with our Deerfield Facility Agreement, partially offset by higher interest expense associated with the deferred obligation with Healthcare Royalty Partners.

Adjusted net loss was $56.3 million, or an adjusted net loss of $0.73 per basic and diluted share, for the quarter ended June 30, 2022. This compares to $53.7 million, or an adjusted net loss of $0.70 per basic and diluted share, for the same quarter in 2021.

About ZYNLONTA® (loncastuximab tesirine-lpyl)

ZYNLONTA® is a CD19-directed antibody drug conjugate (ADC). Once bound to a CD19-expressing cell, ZYNLONTA is internalized by the cell, where enzymes release a pyrrolobenzodiazepine (PBD) payload. The potent payload binds to DNA minor groove with little distortion, remaining less visible to DNA repair mechanisms. This ultimately results in cell cycle arrest and tumor cell death.

The U.S. Food and Drug Administration (FDA) has approved ZYNLONTA (loncastuximab tesirine-lpyl) for the treatment of adult patients with relapsed or refractory (r/r) large B-cell lymphoma after two or more lines of systemic therapy, including diffuse large B-cell lymphoma (DLBCL) not otherwise specified (NOS), DLBCL arising from low-grade lymphoma and also high-grade B-cell lymphoma. The trial included a broad spectrum of heavily pre-treated patients (median three prior lines of therapy) with difficult-to-treat disease, including patients who did not respond to first-line therapy, patients refractory to all prior lines of therapy, patients with double/triple hit genetics and patients who had stem cell transplant and CAR-T therapy prior to their treatment with ZYNLONTA. This indication is approved by the FDA under accelerated approval based on overall response rate and continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial.

ZYNLONTA is also being evaluated as a therapeutic option in combination studies in other B-cell malignancies and earlier lines of therapy.

Use of Non-IFRS Financial Measures

In addition to financial information prepared in accordance with IFRS, this document also contains certain non-IFRS financial measures based on management’s view of performance including:

• Adjusted net loss
• Adjusted net loss per share

Management uses such measures internally when monitoring and evaluating our operational performance, generating future operating plans and making strategic decisions regarding the allocation of capital. We believe that these adjusted financial measures provide useful information to investors and others in understanding and evaluating our operating results in the same manner as our management and facilitate operating performance comparability across both past and future reporting periods. These non-IFRS measures have limitations as financial measures and should be considered in addition to, and not in isolation or as a substitute for, the information prepared in accordance with IFRS. When preparing these supplemental non-IFRS measures, management typically excludes certain IFRS items that management does not believe are indicative of our ongoing operating performance. Furthermore, management does not consider these IFRS items to be normal, recurring cash operating expenses; however, these items may not meet the IFRS definition of unusual or non-recurring items. Since non-IFRS financial measures do not have standardized definitions and meanings, they may differ from the non-IFRS financial measures used by other companies, which reduces their usefulness as comparative financial measures. Because of these limitations, you should consider these adjusted financial measures alongside other IFRS financial measures.

The following items are excluded from adjusted net loss and adjusted net loss per share:

Shared-Based Compensation Expense: We exclude share-based compensation expense from our adjusted financial measures because share-based compensation expense, which is non-cash, fluctuates from period to period based on factors that are not within our control, such as our stock price on the dates share-based grants are issued. Share-based compensation expense has been, and will continue to be for the foreseeable future, a recurring expense in our business and an important part of our compensation strategy.

Certain Other Items: We exclude certain other significant items that we believe do not represent the performance of our business, from our adjusted financial measures. Such items are evaluated by management on an individual basis based on both quantitative and qualitative aspects of their nature. While not all-inclusive, examples of certain other significant items excluded from our adjusted financial measures would be: changes in the fair value of derivatives and the effective interest expense associated with the Facility Agreement with Deerfield, transaction costs associated with debt or equity issuances that are expenses pursuant to IFRS, and the effective interest expense and a cumulative catch-up adjustment associated with the deferred royalty obligation under the royalty purchase agreement with HealthCare Royalty Partners.

See the attached Reconciliation of IFRS Measures to Non-IFRS Measures for explanations of the amounts excluded and included to arrive at the non-IFRS financial measures.
