Breda, the Netherlands

– argenx (Euronext & Nasdaq: ARGX), a global immunology company committed to improving the lives of people suffering from severe autoimmune diseases and cancer, today announced its half year 2021 financial results and provided a second quarter business update and outlook for the remainder of the year.

“The first half of 2021 has been marked by clinical, financial and regulatory achievements for argenx. As we look toward 2022, we believe we are well-positioned to build on the impressive progress we have made with our first-in-class FcRn antagonist, efgartigimod. We are expanding our commercial organization to reach patients living with generalized myasthenia gravis this year and expect that these investments will benefit us in the future and support our growing, differentiated pipeline,” said Tim Van Hauwermeiren, Chief Executive Officer of argenx.

“Beyond myasthenia gravis, we are expanding the breadth of efgartigimod into our fifth and sixth indications, myositis and bullous pemphigoid, and simultaneously investing in potential scientific breakthroughs through our Immunology Innovation Program (IIP). Our first-in-class C2 inhibitor, ARGX-117, emerged from the IIP and has the potential to be our next pipeline-in-a-product opportunity. Collectively, the demonstrated execution this year supports our ‘argenx 2025’ vision and brings us closer than ever to becoming a global, integrated, immunology company,” concluded Mr. Van Hauwermeiren.

HALF YEAR


2021


FINANCIAL RESULTS


(CONSOLIDATED)

DETAILS OF THE FINANCIAL RESULTS

As of January 1, 2021, the Company changed its functional and presentation currency from euro to U.S. dollars, which results in reporting financial highlights in U.S. dollar as compared to euro in prior periods. Historical financials have been converted at the average exchange rate of the related period.

Cash, cash equivalents and current financial assets totaled $2,731.0 million as of June 30, 2021, compared to $1,996.5 million on December 31, 2020. The increase in cash and cash equivalents and current financial assets resulted primarily from (i) the closing of a global offering, which resulted in the receipt of $1,092.1 million in net proceeds in February 2021, (ii) the net receipt of a $73.1 million non-creditable, non-refundable development cost-sharing payment received from Zai Lab as part of the strategic collaboration for efgartigimod in Greater China, (iii) the payment of $98.0 million related to the purchase of the priority review voucher from Bayer HealthCare Pharmaceuticals, and other net cash flows used in operating activities.

Total operating income increased by $453.2 million for the six months ended June 30, 2021 to $487.5 million, compared to $34.3 million for the six months ended June 30, 2020. The increase was primarily due to the recognition of the transaction price as a consequence of the termination of the collaboration agreement with Janssen, resulting in the recognition of $315.1 million and the closing of the strategic collaboration for efgartigimod with Zai Lab, resulting in the recognition of $151.9 million in collaboration revenue.

Research and development expenses increased by $84.7 million for the six months ended June 30, 2021 to $273.9 million, compared to $189.3 million for the six months ended June 30, 2020. The increase in the first six months of 2021 resulted primarily from higher external research and development expenses, mainly related to the efgartigimod program in various indications and other clinical and preclinical programs. Furthermore, the research and development personnel expenses increased due to a planned increase in headcount and the increased costs of the share-based payment compensation plans related to the grant of stock options.

Selling, general and administrative expenses totaled $129.6 million for the six months ended June 30, 2021, compared to $67.9 million for the six months ended June 30, 2020. The increase resulted primarily from higher personnel expenses, including the costs of the share-based payment compensation plans related to the grant of stock options, and consulting fees linked to the preparation of a possible future commercialization of argenx’s lead product candidate efgartigimod.

The change in fair value on non-current financial assets amounted to $11.2 million for the six months ended June 30, 2021, which is the result of the closing of a Series B financing round of AgomAb Therapeutics, for which argenx maintains a profit share in exchange for granting the license for the use of HGF-mimetic antibodies from the SIMPLE Antibody

^TM

platform.

Exchange losses totaled $18.4 million for the six months ended June 30, 2021, compared to an exchange gain of $0.2 million for the six months ended June 30, 2020. As a result of the change in the Company’s functional and presentation currency, the exchange losses for the six months ended June 30, 2021 are reflecting the unfavorable change in euro/U.S. dollar exchange rate, mainly attributable to unrealized exchange rate losses on cash, cash equivalents and current financial asset position in euro.

FINANCIAL GUIDANCE

Based on current plans to fund anticipated operating expenses and capital expenditures, argenx continues to expect its 2021 cash burn to approximately double from 2020. The increased spend will support the Company’s transition to an integrated immunology company, including the build-out of global commercial infrastructure and drug product inventory ahead of the expected launch of efgartigimod in gMG in the U.S, the advancement of its clinical-stage pipeline, including expected global trials of efgartigimod in six indications, and the continued investment in its Immunology Innovation Program.
