Westlake Village, CA, October 28, 2025 – Arcutis Biotherapeutics, Inc. (Nasdaq: ARQT), a commercial-stage biopharmaceutical company focused on developing meaningful innovations in immuno-dermatology, today outlined its strategy to achieve sustainable growth and reported financial results for the quarter ended September 30, 2025. Arcutis will review both topics at its Investor Day, which begins today at 10:30 a.m. Eastern Time (ET).

“Over the past nine years, we have built Arcutis into an undisputed leader in medical dermatology. With ZORYVE, we have developed a portfolio of revolutionary topical treatments that are reshaping the treatment of chronic inflammatory skin diseases and demonstrating sustainable commercial momentum across all strengths and indications,” said Frank Watanabe, president and chief executive officer. “This success provides a tremendous foundation for sustained, long-term growth—offering the opportunity to reinvest in the ZORYVE franchise, systematically evaluate new opportunities, and expand our pipeline with new molecules that leverage our deep expertise in dermatology, as well as our best-in-class development and commercialization capabilities.”

In today's Investor Day presentation, Arcutis management will discuss how the Company intends to:

•Grow the current ZORYVE franchise through continued conversion of the topical corticosteroid market, where 17 million prescriptions are written by dermatology clinicians every year for patients in ZORYVE-approved indications;

•Expand ZORYVE into new markets through potential additional indications, beginning with Phase 2 proof-of-concept trials evaluating ZORYVE foam 0.3% in vitiligo and hidradenitis suppurativa;

•Build the Company's clinical pipeline with the advancement of ARQ-234 and potentially through external innovation;

•Allocate capital responsibly to fuel this strategy, as well as improve the Company's long-term financial outlook; and

•Drive to potential peak ZORYVE sales of $2.6–$3.5 billion per annum across current and potential future indications, based on an assumed 15%-20% share of topical corticosteroid volume.

ZORYVE - a highly potent and selective phosphodiesterase-4 (PDE4) inhibitor in once-daily cream and foam formulations, approved in the United States for the treatment of plaque psoriasis, atopic dermatitis, and seborrheic dermatitis.

•ZORYVE net product sales for the third quarter of 2025 were $99.2 million, reflecting 22% sequential growth over the second quarter of 2025 and 122% year-over-year growth. Sequential growth was driven by increasing demand across products, the launch of ZORYVE foam 0.3% in plaque psoriasis of the scalp and body, and improved gross-to-net (GTN) pricing.

•Following FDA approval in early October, the Company will launch ZORYVE cream 0.05% for the treatment of atopic dermatitis in children ages 2 to 5 by the end of October.

•The Company has begun enrolling patients in Phase 2 proof-of-concept studies with ZORYVE foam 0.3% for the treatment of patients with vitiligo, as well as patients with hidradenitis suppurativa, the first trials in the Company's effort to investigate further indication expansion opportunities for ZORYVE.

•The Company is preparing to initiate a Phase 1 study of ARQ-234, a fusion protein that is a potent and highly selective checkpoint agonist of the CD200 receptor being developed as a potential biologic treatment in atopic dermatitis.

•ZORYVE cream and ZORYVE foam were awarded the "2025 Best of Beauty Breakthrough Award" by Allure, making it the first FDA-approved medication for atopic dermatitis, plaque psoriasis, and seborrheic dermatitis to win this prestigious award.

•Arcutis was named to Fortune Best Workplaces in BioPharma™ 2025 list for the fourth consecutive year.

•The Company obtained one new U.S. patent in Q3 2025 related to topical roflumilast foam compositions.

Product revenues for the quarter ended September 30, 2025 were $99.2 million compared to $44.8 million for the corresponding period in 2024. Revenues for the quarter were $30.5 million for ZORYVE cream 0.3%, $18.9 million for ZORYVE cream 0.15%, and $49.8 million for ZORYVE topical foam 0.3%. The year-over-year increase was primarily due to increased unit demand. GTN rates remained favorable for ZORYVE, driven by a high percentage of prescriptions being reimbursed.

Cost of sales for the quarter ended September 30, 2025 was $8.7 million compared to $5.5 million for the corresponding period in 2024, due to increasing ZORYVE sales.

Research and development (R&D) expenses for the quarter ended September 30, 2025 were $19.6 million compared to $19.5 million for the corresponding period in 2024. Expenses remained consistent year over year, as increased development costs for roflumilast in pediatric atopic dermatitis were largely offset by a decrease in development costs for ARQ-255 and preclinical expenses.

Selling, general, and administrative (SG&A) expenses for the quarter ended September 30, 2025 were $62.4 million compared to $58.8 million for the corresponding period in 2024. The year-over-year increase was primarily driven by increased sales and marketing and personnel-related expenses due to the Company's continued commercialization efforts for ZORYVE.

Net income was $7.4 million, or $0.06 per basic and diluted earnings per share, for the quarter ended September 30, 2025 compared to a net loss of $41.5 million, or $0.33 per basic and diluted loss per share, for the corresponding period in 2024.

Cash, cash equivalents, restricted cash, and marketable securities were $191.4 million as of September 30, 2025, compared to $228.6 million as of December 31, 2024. Net cash used in operating activities was $1.8 million during the third quarter.

•Arcutis anticipates net product revenue of between $455 million and $470 million for the full year 2026.

Arcutis management will host a virtual Investor Day today at 10:30 a.m. ET to discuss its strategy for sustained long-term growth, as well as financial results for the third quarter. The webcast for this event can be accessed at the “Events” section of the Company’s website. The replay of the webcast will be available on the Arcutis website following the event.
