Overview

We are a commercial-stage biopharmaceutical company focused on developing and commercializing treatments for dermatological diseases with high unmet medical needs. Our current portfolio is comprised of highly differentiated topical and systemic treatments with significant potential to treat immune-mediated dermatological diseases and conditions. We believe we have built a leading platform for dermatologic product development and commercialization. Our strategy is to focus on validated biological targets, and to use our drug development platform and deep dermatology expertise to develop and commercialize differentiated products that have the potential to address the major shortcomings of existing therapies in our targeted indications. We believe this strategy uniquely positions us to rapidly advance our goal of bridging the treatment innovation gap in dermatology, while maximizing our probability of technical success and financial resources.

We launched our lead product, ZORYVE® (roflumilast) cream 0.3% (ZORYVE cream 0.3%), in August 2022 after obtaining our initial U.S. Food and Drug Administration (FDA) approval for the treatment of plaque psoriasis, including psoriasis in the intertriginous areas (e.g. groin or axillae), in individuals 12 years of age or older. ZORYVE cream 0.3% is a once-daily topical formulation of roflumilast, a highly potent and selective phosphodiesterase-4 (PDE4) inhibitor. ZORYVE cream 0.3% is approved for once-daily treatment of mild, moderate, and severe plaque psoriasis with no limitations on location or duration of use. In October 2023, we received FDA approval for an expanded indication in plaque psoriasis down to 6 years of age. In September 2025, we submitted a supplemental New Drug Application (sNDA) to FDA to expand the indication of ZORYVE cream 0.3% for the treatment of plaque psoriasis in children down to the age of 2. In June 2023, we had our first commercial launch outside of the United States following Health Canada approval of ZORYVE cream 0.3% for the treatment of plaque psoriasis in individuals 12 years or age or older.

In December 2023, we received FDA approval for ZORYVE® (roflumilast) topical foam 0.3% (ZORYVE foam) for the treatment of seborrheic dermatitis in individuals aged 9 years and older, with no limitation on severity, location, or duration of use. ZORYVE foam is a once-daily steroid-free foam and, as a PDE4 inhibitor, is the first drug approved for the treatment of seborrheic dermatitis with a new mechanism of action in over two decades. ZORYVE foam became commercially available in the United States in January 2024, and was approved by Health Canada in October 2024 and became commercially available in Canada in December 2024. We also received FDA approval for ZORYVE foam for the treatment of plaque psoriasis of the scalp and body in adults and adolescents ages 12 and older in May 2025, followed by commercial launch in June 2025.

In addition to the approval of ZORYVE cream 0.3% for plaque psoriasis and ZORYVE foam for seborrheic dermatitis and plaque psoriasis of the scalp and body, we also received FDA approval for and commercially launched ZORYVE (roflumilast) cream 0.15% (ZORYVE cream 0.15%) in July 2024 for the treatment of mild to moderate atopic dermatitis in adults and pediatric patients 6 years of age and older, with no limitation on location, body surface area treated, concomitant use, or duration of use specified in the approved labelling. ZORYVE cream 0.15% was also approved by Health Canada in March 2025 and commercially launched in April 2025. We also received FDA approval for ZORYVE cream 0.05% for treatment of mild to moderate atopic dermatitis in children 2 to 5 years of age and plan to commercially launch in October 2025. ZORYVE cream 0.15% and 0.05% are once-daily, steroid-free creams that provide rapid disease clearance and significant reduction in itch and have been specifically developed to be treatment options for long-term disease control. In June 2025, we initiated INTEGUMENT-INFANT, a Phase 2 study to evaluate the safety and efficacy of investigational ZORYVE cream 0.05% in infants as young as 3 months to less than 2 years with atopic dermatitis, which potentially could serve as the basis for a further expansion of the indication for ZORYVE cream 0.05% to this group of patients.

In July 2024, we entered into a co-promotion agreement with Kowa Pharmaceuticals, Inc. (Kowa) to leverage Kowa's primary care sales force to exclusively market and promote ZORYVE in the United States to primary care practitioners and pediatricians for all FDA-approved indications until at least July 2029. Under the terms of the agreement, Kowa will receive a commission from net sales attributed to Kowa. Promotion of ZORYVE in primary care and pediatrics under the Kowa agreement began in late September 2024.

In addition to ZORYVE, we had developed ARQ-255, a deep penetrating topical formulation of ivarmacitinib, a potent and highly selective topical Janus kinase type 1 (JAK 1) inhibitor, for the treatment of alopecia areata. Following the completion of a Phase 1b study in the middle of 2025, we elected to halt further development of the program.

In September 2022, we acquired Ducentis BioTherapeutics LTD (Ducentis) and its lead asset, DS-234 (now ARQ-234), a fusion protein that is a potent and highly selective checkpoint agonist of the CD200 Receptor (CD200R). Currently in the preclinical stage, we plan to develop ARQ-234 in atopic dermatitis, where we believe it could be a potentially highly complementary biologic treatment option to ZORYVE cream 0.15% in that indication, if approved. ARQ-234 could potentially be used to treat other inflammatory conditions as well. The Company submitted an Investigational New Drug (IND) application to the FDA in July 2025, and anticipates commencing a Phase 1 study of ARQ-234 in the first quarter of 2026.

We have incurred annual net losses in each year since inception, including net losses of $33.5 million and $129.3 million for the nine months ended September 30, 2025 and 2024, respectively. As of September 30, 2025, we had an accumulated deficit of $1,155.5 million and cash, cash equivalents, restricted cash, and marketable securities of $191.4 million. As of September 30, 2025, we had $100.0 million outstanding under the Loan Agreement. We paid down $100.0 million of principal related to the Loan Agreement using available cash in October 2024, with the right to re-draw that principal for a defined period.

While we generated net income for the quarter ended September 30, 2025, the extent of any net income or losses for future periods is uncertain and we may continue to incur net losses in future periods. We expect to continue to incur significant expenses as we commercialize ZORYVE, and as we advance our product candidates and label extensions through clinical trials, regulatory submissions and commercialization. We expect to incur commercialization expenses related to the sales, marketing, manufacturing, and distribution of ZORYVE, while we focus our clinical development spend on ARQ-234 and ZORYVE label expansions. While we do not anticipate the need to obtain funds through financings or other sources to support our current planned operations, if our available cash and marketable securities balances, amounts available under the Loan Agreement, and anticipated future cash flows from operations are insufficient to cover these expenses, we may need to fund our operations through equity or debt financings or other sources, such as future potential collaboration agreements. Adequate funding may not be available to us on acceptable terms, or at all. Any failure to obtain sufficient funds on acceptable terms if or when needed could have a material adverse effect on our business, results of operations, and financial condition.

We rely on third parties to conduct our nonclinical studies and clinical trials and for manufacturing and supply of our product candidates. We have no internal manufacturing capabilities and we rely on third parties, many of whom are single source suppliers, for our nonclinical and clinical trial materials, as well as the commercial supply of our products.

Components of Our Results of Operations

Revenue

In August 2022, in conjunction with the launch of our first FDA-approved product, ZORYVE cream 0.3%, we began to recognize revenue from product sales, net of rebates, chargebacks, discounts and other adjustments. We also began recognizing revenue net of deductions for ZORYVE cream 0.3% in Canada in June 2023, ZORYVE foam for seborrheic dermatitis in the United States in January 2024, ZORYVE cream 0.15% for atopic dermatitis in July 2024, ZORYVE foam for seborrheic dermatitis in Canada in December 2024, ZORYVE cream 0.15% in Canada in April 2025, and ZORYVE foam for scalp and body psoriasis in the United States in June 2025. Additionally, if our development efforts for our other product candidates and ZORYVE label expansions are successful and result in regulatory approval, we may generate additional revenue in the future from sales of such other products and label expansions.

Other Revenue

Other revenue relates to our license agreements, primarily the Sato Agreement and the Huadong Agreement. See Note 6 to the condensed consolidated financial statements for additional information.

Operating Expenses

Cost of sales includes direct and indirect costs related to the manufacturing and distribution of ZORYVE, including raw materials, third-party manufacturing costs, packaging services, and freight-in, as well as third-party royalties payable on our net product sales and amortization of intangible assets associated with ZORYVE.

Prior to the date on which the initial regulatory approval was received for each product, costs of inventory production were recorded as research and development expense. Subsequent to initial regulatory approval, costs of production are capitalized into inventory, and as that inventory is sold and revenue is recognized, the cost of the inventory is recognized in cost of sales. During the second half of 2025, the Company expects to have sold its remaining finished goods inventory produced prior to regulatory approval for which the cost was previously recognized as research & development expense. As of September 30, 2025 and December 31, 2024, the value of this inventory, mostly at the raw materials stage, was approximately $0.2 million and $5.5 million, respectively.

Since our inception, we have focused significant resources on our research and development activities, including conducting nonclinical studies and clinical trials, manufacturing development efforts, activities related to regulatory filings for our product candidates, and medical affairs activities related to ZORYVE. Research and development costs are expensed as incurred. These costs include direct program expenses, which are payments made to third parties that specifically relate to our research and development, such as payments to clinical research organizations, clinical investigators, manufacturing of clinical material, nonclinical testing and consultants. In addition, employee costs, including salaries, payroll taxes, benefits, stock-based compensation and travel for employees contributing to research and development activities are classified as research and development costs. We allocate direct external costs on a program specific basis (topical roflumilast program and CD200R program). Our internal costs are primarily related to personnel or professional services and apply across programs, and thus are not allocable on a program specific basis.

We expect to continue to incur research and development expenses in the future as we develop our product candidates. In particular, we expect to incur research and development expenses for the development of ARQ-234 for atopic dermatitis and for ZORYVE label expansions and life cycle management.

We have entered, and may continue to enter, into license agreements to access and utilize certain molecules for the treatment of dermatological diseases and disorders. We evaluate if the license agreement is an acquisition of an asset or a business. To date, none of our license agreements have been considered to be an acquisition of a business. For asset acquisitions, the upfront payments, as well as any future milestone payments made before product approval, are immediately recognized as research and development expense when due, provided there is no alternative future use of the rights in other research and development projects.

The successful development of our product candidates is highly uncertain. At this time, we cannot reasonably estimate the nature, timing, or costs required to complete the remaining development of ZORYVE cream and ZORYVE foam, and ARQ-234 or any other product candidates. This is due to the numerous risks and uncertainties associated with the development of product candidates. See “Risk Factors” for a discussion of the risks and uncertainties associated with the development of our product candidates.

Our selling, general and administrative expenses consist primarily of salaries and related costs, including payroll taxes, benefits, stock-based compensation, and travel, and costs related to sales and marketing of ZORYVE. Other selling, general and administrative expenses include legal costs of pursuing patent protection of our intellectual property, insurance and professional services fees for auditing, tax, and general legal services. The commission paid to Kowa under our co-promotion agreement is recorded as a selling expense. We expect our selling, general and administrative expenses to continue to increase in the future as we continue to commercialize ZORYVE and potentially other product candidates and support our operations, including increased expenses related to legal, accounting, insurance, regulatory, and tax-related services associated with maintaining compliance with exchange listing and SEC requirements, directors and officers liability insurance premiums, and investor relations activities.

Other income, net primarily consists of interest income earned on our cash, cash equivalents, and marketable securities, as well as changes in the fair value of the derivative related to our debt. See Note 8 to the condensed consolidated financial statements for additional information.

Interest expense is related to interest incurred on our long-term debt.

Provision for Income Taxes

Provision for income taxes is primarily related to foreign income tax expense and foreign withholding taxes incurred in relation to a license agreement.
