Exhibit 99.1
Xencor Reports First Quarter 2023 Financial Results

-- Management to Host Conference Call at 4:30 p.m. ET Today --

PASADENA, Calif.--May 8, 2023-- Xencor, Inc. (NASDAQ:XNCR), a clinical-stage biopharmaceutical company developing engineered antibodies and cytokines for the treatment of patients with cancer and autoimmune diseases, today reported financial results for the first quarter ended March 31, 2023 and provided a review of recent business and clinical highlights.

“In the first quarter, we and our partners continued to enroll patients across multiple Phase 1 and Phase 2 clinical studies of XmAb drug candidates in oncology and autoimmune diseases. Two new programs are planned to advance into clinical development this year, XmAb662, our engineered IL12-Fc cytokine, on track to start a Phase 1 study mid-year, and XmAb541, our CLDN6 x CD3 bispecific antibody for ovarian cancer, for which we anticipate submitting the IND by year end,” said Bassil Dahiyat, Ph.D., president and chief executive officer at Xencor. “And recently, we added to our team the expertise and talents of Nancy Valente, M.D., who will lead our clinical programs as our new executive vice president and chief development officer.”

Program and Corporate Updates

XmAb564 (IL2-Fc): The Company will present updated results from the Phase 1a single-ascending dose study in healthy volunteers at European Alliance of Associations for Rheumatology (EULAR) Congress, being held from May 31 to June 1, in Milan, Italy. The update will include additional biomarker data. Data previously presented demonstrate a single dose, administered subcutaneously in healthy volunteers, was well tolerated and generated durable, dose-dependent and selective expansion of regulatory T cells.

XmAb104 (PD-1 x ICOS): XmAb104 is a bispecific antibody that targets PD-1, an immune checkpoint receptor, and ICOS, an immune co-stimulatory receptor, to selectively activate the tumor microenvironment. Initial dose-escalation data from a Phase 1 study, presented at ASCO 2022, indicates that XmAb104 was well tolerated and exhibited a distinct safety profile compared to other clinical-stage ICOS programs. Anti-tumor activity was observed in patients, and biomarker activity was consistent with engagement with T cells. The Company has opened an expansion portion in the study (Part C) to evaluate XmAb104 in combination with ipilimumab in patients with microsatellite stable or proficient mismatch repair colorectal cancer.

Preclinical Data Presentation: Preclinical data generated from engineered CD28 bispecific antibodies targeting the solid tumor antigens CEACAM5, ENPP3, mesothelin, STEAP1 and Trop-2 were presented at the American Association for Cancer Research (AACR) Annual Meeting in April 2023.

Corporate Update: Nancy Valente, M.D., was appointed as Xencor’s Executive Vice President, Chief Development Officer, effective May 1, having previously served as an independent member of the Company’s Board of Directors from September 2022 through April 2023. Dr. Valente brings with her more than 20 years of experience in late-stage biopharmaceutical product development. She most recently served as a senior vice president at Genentech, a member of the Roche Group, and as its global head and co-lead of global product development of its oncology and hematology therapeutic area.

Progress Across Partnered Programs

Alexion Pharmaceuticals, Inc.: In April 2023, Ultomiris® (ravulizumab-cwvz), which incorporates an Xtend™ Fc domain, was recommended for marketing authorization in the EU for the treatment of adult patients with neuromyelitis optica spectrum disorder (NMOSD) who are anti-aquaporin-4 antibody positive. In addition, AstraZeneca recently announced that a Phase 3 study of Ultomiris has been initiated in cardiac surgery-associated acute kidney injury. In the first quarter of 2023, Xencor earned $10.5 million of royalty revenue from Alexion on net sales of Ultomiris.

Ultomiris is a registered trademark of Alexion Pharmaceuticals, Inc.

Financial Results for the First Quarter Ended March 31, 2023

Cash, cash equivalents, receivables and marketable debt securities totaled $568.2 million as of March 31, 2023, compared to $613.5 million on December 31, 2022.

Revenues for the first quarter ended March 31, 2023 were $19.0 million, compared to $85.5 million for the same period in 2022. Total revenues earned in the first quarter of 2023 included milestone revenue earned from Xencor’s Janssen collaboration and royalties from the Alexion agreement, compared to revenue earned from the Janssen collaboration, milestone revenue from Astellas, and royalties from the Alexion, MorphoSys and Vir agreements in the first quarter of 2022.

Research and development expenses for the first quarter ended March 31, 2023 were $64.4 million, compared to $47.8 million for the same period in 2022. Increased research and development spending for first quarter of 2023 compared to 2022 reflects increased spending on the Company’s development programs including XmAb541 (CLDN6 x CD3) and XmAb564 and other research and early-stage programs.

General and administrative expenses for the first quarter ended March 31, 2023 were $13.9 million, compared to $11.3 million in the same period in 2022. Increased general and administrative spending for the first quarter of 2023 compared to 2022 reflects increased facility expenses and additional spending on professional fees.

Non-cash, stock-based compensation expense for the first quarter ended March 31, 2023 was $12.6 million, compared to $10.8 million for the same period in 2022.

Net loss for the first quarter ended March 31, 2023 was $60.8 million, or $(1.02) on a fully diluted per share basis, compared to a net income of $23.6 million, or $0.39 on a fully diluted per share basis, for the same period in 2022. Net loss reported for the first quarter of 2023 compared to net income for the same period in 2022 is primarily due to decreased royalties from the Vir agreement.

The total shares outstanding were 60,381,600 as of March 31, 2023, compared to 59,529,192 as of March 31, 2022.
