Amsterdam,the Netherlands – argenx SE (Euronext & Nasdaq: ARGX), a global immunology company committed to improving the lives of people suffering from severe autoimmune diseases, today announced its third quarter 2022 financial results and provided a business update and outlook for the remainder of the year.

“We had a strong third quarter of our global VYVGART launch now underway in our priority territories of the U.S., Japan and the EU. I am proud of what our teams have achieved, working cross-functionally to set a new treatment standard in gMG and serve as many patients as possible. Looking ahead, we are ready to support a SC efgartigimod launch in the first half of 2023 so that gMG patients can have multiple ways to individualize their treatment,” said Tim Van Hauwermeiren, Chief Executive Officer of argenx. “gMG is also just the beginning and we are committed to advancing our immunology pipeline of efgartigimod, ARGX-117 and ARGX-119 with eight ongoing clinical trials in severe autoimmune diseases and more to start by the end of the year. We believe we are well on our way to realizing our goal of becoming a leading, multi-product immunology company and that we have the right team, a differentiated pipeline, and a sustainable discovery engine to continue innovating on behalf of patients.”

DETAILS OF THE FINANCIAL RESULTS

Totaloperating income for the third quarter and year-to-date in 2022 was $146.5 million and $263.2 million, respectively, compared to $7.1 million and $505.7 million for the same periods in 2021, and consists of:

Product net sales from the sales of VYVGART for the three months ended September 30, 2022<br>were $131.3 million. The product net sales in the nine months ended September 30, 2022 were $227.3 million. No product net sales<br>were recognized during the same period in 2021.
Collaboration revenue for the third quarter and year-to-date in 2022 was $6.7 million and $9.3 million, respectively, compared<br>to $0.1 million and $471.3 million for the same periods in 2021. The collaboration revenue during the three months ended September 30,<br>2022 primarily relates to milestone revenue of the €5 million triggered by the option exercised by LEO Pharma to enter into a commercial<br>license for ARGX-112. The collaboration revenue for the three and nine months ended September 30, 2021 was primarily attributable<br>to the recognition of the transaction price as a consequence of the termination of the collaboration agreement with Janssen, resulting<br>in the recognition of $315.1 million and the closing of the strategic collaboration for efgartigimod with Zai Lab, resulting in the recognition<br>of $151.9 million in collaboration revenue.
Other operating income for the third quarter and year-to-date in 2022 was $8.5 million, and $26.6<br>million, respectively, compared to $6.2 million and $34.5 million for the same periods in 2021. During the nine months ended September 30,<br>2022, and September 30, 2021, the fair value of the argenx profit share in AgomAb Therapeutics NV increased by $4.3 million and $11.2<br>million respectively. The increase is a result of the extension of a Series B financing round by AgomAb for which argenx maintains<br>a profit share in exchange for granting the license for the use of HGF-mimetic antibodies from the SIMPLE Antibody™ platform.

Totaloperating expenses for the third quarter and year-to-date in 2022 were $355.1 million and $869.1 million, respectively, compared to $220.1 million and $623.6 million for the same periods in 2021, and consists of:

Cost of sales for the third quarter and year-to-date in 2022 was $10.3 million and $16.6 million,<br>respectively. The cost of sales were recognized with respect to the sale of VYVGART during 2022. There were no cost of sales recognized<br>in the comparable prior year periods.
Research and development expenses for the third quarter and year-to-date in 2022 were $236.7 million<br>and $515.6 million, respectively, compared to $139.4 million and $413.3 million for the same periods in 2021. The research and development<br>expenses mainly relate to external research and development expenses and personnel expenses incurred in the clinical development of efgartigimod<br>in various indications and the expansion of other clinical and preclinical pipeline candidates. The increase in research and development<br>expense during the third quarter 2022 is mainly driven by the recognition of the priority review voucher submitted with the BLA filing<br>for SC efgartigimod for the treatment of gMG, which resulted in an expense of $99.1 million.
Selling, general and administrative expenses for the third quarter and year-to-date in 2022 were<br>$108.2 million and $336.8 million, respectively, compared to $80.6 million and $210.2 million for the same periods in 2021. The selling,<br>general and administrative expenses mainly relate to professional and marketing fees linked to the commercialization of VYVGART in the<br>U.S., Japan and the EU and personnel expenses.

Exchangelosses for the third quarter and year-to-date in 2022 were $39.6 million and $93.0 million, respectively, compared to $17.6 million and $36.0 million for the same periods in 2021. Exchange losses are mainly attributable to unrealized exchange rate losses on cash, cash equivalents and current financial assets position in Euro.

Incometax for the third quarter and year-to-date in 2022 was $6.0 million and $17.1 of tax income, respectively, compared to $2.7 million and $15.6 million of tax expense for the same periods in 2021. Tax income for the three months ended September 30, 2022 consists of $7.3 million of income tax expense and $13.3 million of deferred tax income, compared to $4.3 million of income tax expense and $1.6 million of deferred tax income for the same period in 2021.

Netloss for the third quarter and year-to-date in 2022 was $235.0 million and $671.0 million, respectively, compared to net loss of $233.6 million and $170.4 million for the same periods in 2021.

Cash,cash equivalents and current financial assets totaled $2,385.5 million as of September 30, 2022, compared to $2,336.7 million as of December 31, 2021. Cash and cash equivalents and current financial assets increased primarily as a result of the closing of a global offering of shares, which resulted in the receipt of $761.0 million in net proceeds in March 2022, offset by net cash flows used in operating activities.

FINANCIAL GUIDANCE

Based on current plans to fund anticipated operating expenses and capital expenditures, argenx continues to expect its 2022 cash burn to be up to $1 billion. This will support the global VYVGART launches, clinical development of efgartigimod in 10 indications and ARGX-117 in two indications, investment in the global supply chain, and continued focus on pipeline expansion through the Immunology Innovation Program.
