Westlake Village, CA, February 25, 2025 – Arcutis Biotherapeutics, Inc. (Nasdaq: ARQT), a commercial-stage biopharmaceutical company focused on developing meaningful innovations in immuno-dermatology, today reported financial results for the quarter and year ended December 31, 2024, and provided a business update.

“Our success in 2024 was driven by growing ZORYVE momentum, including commercial launches for two new indications for ZORYVE, and our pricing and access strategy that led to strong commercial and government reimbursement. ZORYVE is the number one prescribed branded non-steroidal topical, due to its compelling value proposition of effectively and safely relieving multiple inflammatory skin conditions anywhere on the body for any duration,” said Frank Watanabe, president and chief executive officer. “We are also continuing to advance our product pipeline and, along with strong stewardship of our financial resources and management of expenses, we believe we are well positioned to realize our mission of addressing unmet needs and the lack of innovation in medical dermatology.”

•U.S. demand for ZORYVE cream 0.3% in plaque psoriasis continues to grow, with over 360,000 prescriptions filled since launch by over 14,000 unique prescribers, reflecting the high levels of patient and physician satisfaction with the ZORYVE cream clinical profile. ZORYVE cream is covered by the three largest Pharmacy Benefit Managers (PBMs) and multiple other commercial insurers, and during the quarter the Company expanded its Medicaid coverage to two additional states, Ohio and Illinois. The Company aims to obtain Medicaid coverage in additional states, as well as some Medicare coverage, during 2025.

•Initial launch of ZORYVE cream 0.15% in atopic dermatitis has been strong with over 33,000 prescriptions filled since launch, and is covered as a line extension by two of the largest national PBMs. The Company anticipates continued improvement in coverage during 2025.

•Demand for ZORYVE foam, 0.3% in seborrheic dermatitis continues to grow robustly each quarter, with over 246,000 prescriptions filled since launch, reflecting the high unmet need in this disease. ZORYVE foam is also covered by the three largest PBMs and has steadily improved coverage over the course of 2024. ZORYVE foam has gained Medicaid coverage in line with ZORYVE cream 0.3% and is nearing a steady state GTN.

•The Company submitted an sNDA for ZORYVE foam for scalp and body psoriasis to the FDA based on the positive results from the pivotal ARRECTOR Phase 3 trial and a Phase 2b trial, which was accepted by the FDA in September with a PDUFA action date set for May 22, 2025.
