*Not applicable

Product revenue, net, for ZORYVE cream 0.3% increased by $8.5 million for the three months ended September 30, 2025 compared to the three months ended September 30, 2024, primarily driven by higher end customer demand in the United States and Canada.

Product revenue, net, for ZORYVE foam increased by $29.5 million for the three months ended September 30, 2025 compared to the three months ended September 30, 2024, primarily driven by higher end customer demand related to seborrheic dermatitis in the United States, the commercial launch of ZORYVE foam for the treatment of plaque psoriasis of the scalp and body in the United States in June 2025, as well as the commercial launch of ZORYVE foam for seborrheic dermatitis in Canada in December 2024.

Product revenue, net, for ZORYVE cream 0.15% increased by $16.5 million for the three months ended September 30, 2025 compared to the three months ended September 30, 2024, primarily driven by higher end customer demand and, to a lesser extent, net price improvement in the United States.

Cost of sales increased by $3.2 million for the three months ended September 30, 2025 compared to the three months ended September 30, 2024. The increase was due to the increase in royalty expense and cost of products sold, consistent with the growth in ZORYVE cream and foam product revenue.

Research and development expenses increased slightly by $0.1 million, or 1%, for the three months ended September 30, 2025 compared to the three months ended September 30, 2024. Direct external costs decreased due to lower ARQ-234 preclinical costs and the completion of a Phase 1b study in our topical JAK inhibitor program for the treatment of alopecia areata, which we elected to halt. These decreases were partially offset by an increase in expenses related to a Phase 2 study of ZORYVE cream 0.05% for the treatment of atopic dermatitis in infants.

Selling, general and administrative expenses increased by $3.6 million, or 6%, for the three months ended September 30, 2025 compared to the three months ended September 30, 2024. The increase was primarily due to continued commercialization efforts and growing revenue for ZORYVE and consisted of $2.2 million in compensation and personnel-related expenses and $2.0 million in sales and marketing expenses, partially offset by decreases in costs related to professional services.

Other income, net decreased by $2.1 million for the three months ended September 30, 2025 compared to the three months ended September 30, 2024, primarily due to less interest income resulting from lower cash, cash equivalents, and marketable securities balances, coupled with the impact of lower investment yields.

Interest expense decreased by $3.6 million for the three months ended September 30, 2025 compared to the three months ended September 30, 2024, due to a lower outstanding principal balance on our long-term debt driven by our $100.0 million principal paydown in October 2024, coupled with the impact of lower interest rates. See Note 8 to the condensed consolidated financial statements for additional information.

Comparison of the Nine Months Ended September 30, 2025 and 2024

We began recording U.S. product revenue in the third quarter of 2022 following the FDA approval and subsequent commercial launch of ZORYVE cream 0.3% in August 2022, Canada product revenue in the second quarter of 2023 following the Health Canada approval and subsequent commercial launch of ZORYVE cream 0.3% in June 2023, and additional U.S. revenue in the first quarter of 2024 following the FDA approval and subsequent commercial launch of ZORYVE foam for seborrheic dermatitis in January 2024. In the third quarter of 2024, we began recording U.S. product revenue following the FDA approval and subsequent commercial launch of ZORYVE cream 0.15% in July 2024. In the fourth quarter of 2024, we began recording Canada product revenue following the Health Canada approval and subsequent commercial launch of ZORYVE foam for seborrheic dermatitis in December 2024. In the second quarter of 2025, we began recording Canada product revenue following the Health Canada approval and subsequent launch of ZORYVE cream 0.15% in April 2025, as well as U.S. product revenue following the FDA approval and subsequent commercial launch of ZORYVE foam for scalp and body psoriasis in June 2025.

*Not applicable

Product revenue, net, for ZORYVE cream 0.3% increased by $27.2 million for the nine months ended September 30, 2025 compared to the nine months ended September 30, 2024, primarily driven by higher end customer demand in the United States and Canada.

Product revenue, net, for ZORYVE foam increased by $78.8 million for the nine months ended September 30, 2025 compared to the nine months ended September 30, 2024, primarily driven by higher end customer demand for seborrheic dermatitis in the United States, the commercial launch of ZORYVE foam for plaque psoriasis of the scalp and body in the United States in June 2025, as well as the commercial launch of ZORYVE foam for seborrheic dermatitis in Canada in December 2024.

Product revenue, net, for ZORYVE cream 0.15% increased by $41.3 million for the nine months ended September 30, 2025, primarily driven by its commercial launch in the United States in July 2024.

Other Revenue

Other revenue of $2.0 million for the nine months ended September 30, 2025 relates to license revenues received in connection with the Huadong Agreement. Other revenue for the nine months ended September 30, 2024 includes $25.0 million received as an upfront payment in connection with the Sato Agreement and a $3.0 million milestone payment received in connection with the Huadong Agreement. See Note 6 to the condensed consolidated financial statements for additional information.

Cost of sales increased by $12.8 million for the nine months ended September 30, 2025, compared to the nine months ended September 30, 2024, and was due to a $2.5 million increase in amortization expense recorded in connection with the AstraZeneca milestones achieved in the first quarter of 2025, with the remainder due to the increase in royalty expense and cost of products sold consistent with the growth in ZORYVE cream and foam product revenue.

Research and development expenses decreased by $5.3 million, or 9%, for the nine months ended September 30, 2025 compared to the nine months ended September 30, 2024. The decrease was primarily due to lower ARQ-234 preclinical costs and the completion of a Phase 1b study in our topical JAK inhibitor program for the treatment of alopecia areata, which we elected to halt.

We expect research and development expenses in future periods to increase primarily due to the development and clinical study associated with ARQ-234 and ZORYVE life cycle management.

Selling, general and administrative expenses increased by $23.8 million, or 14%, for the nine months ended September 30, 2025 compared to the nine months ended September 30, 2024. The increase was primarily due to continued commercialization efforts and growing revenue for ZORYVE, and consisted of $13.4 million higher sales and marketing expenses and $12.1 million higher compensation and personnel-related expenses. These increases were partially offset by a decrease in professional services costs.

Other income, net decreased by $6.6 million for the nine months ended September 30, 2025 compared to the nine months ended September 30, 2024, primarily due to less interest income resulting from lower cash, cash equivalents, and marketable securities balances, coupled with the impact of lower investment yields.

Interest expense decreased by $12.5 million for the nine months ended September 30, 2025 compared to the nine months ended September 30, 2024, due to a lower outstanding principal balance on our long-term debt driven by our $100.0 million principal paydown in October 2024, coupled with the impact of lower interest rates. See Note 8 to the condensed consolidated financial statements for additional information.

Liquidity, Capital Resources, and Requirements

Sources of Liquidity

Our primary sources of capital to date have been private placements of preferred stock, our IPO completed in January 2020, our follow-on financings in October 2020, February 2021, August 2022, October 2023, and March 2024, our Loan Agreement, our ATM program, and revenue from the sale of ZORYVE cream 0.3%, ZORYVE cream 0.15%, and ZORYVE foam. We have incurred annual operating losses since our inception and have an accumulated deficit as a result of ongoing efforts to develop and commercialize our products and product candidates, including conducting nonclinical and clinical trials and providing selling, general and administrative support for these operations. As of September 30, 2025, we had cash, cash equivalents, restricted cash, and marketable securities of $191.4 million, and an accumulated deficit of $1,155.5 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 on October 8, 2024, with the right to re-draw that principal for a defined period. See Note 8 to the condensed consolidated financial statements for additional information.

We believe that our existing capital resources will be sufficient to meet the projected operating requirements for at least 12 months from the date of issuance of our financial statements.

If our capital resources are insufficient to satisfy our requirements, we may need to fund our operations through the sale of our equity securities, accessing or incurring additional debt, entering into licensing or collaboration agreements with partners, grants, or other sources of financing. There can be no assurance that sufficient funds will be available to us at all or on attractive terms when needed from these sources. If we are unable to obtain additional funding from these or other sources if or when needed it may be necessary to significantly reduce our current rate of spending through, among other things, reductions in staff and delaying, scaling back, or stopping certain research and development programs, nonclinical studies, clinical trials or other development activities, and commercialization efforts. In addition, market conditions impacting financial institutions could impact our ability to access some or all of our cash, cash equivalents and marketable securities, and we may be unable to obtain alternative funding when and as needed on acceptable terms, if at all.

We have based our projected operating requirements on assumptions that may prove to be incorrect and we may use all our available capital resources sooner than we expect. Because of the numerous risks and uncertainties associated with research, development, and commercialization of pharmaceutical products, we are unable to estimate the exact amount of our operating capital requirements. Any future funding requirements will depend on many factors, including, but not limited to:

•the timing, receipt, and amount of sales of any current and future products;

•the scope, progress, results, and costs of researching and developing our product candidates or any future product candidates, and conducting nonclinical studies and clinical trials, in particular our planned or ongoing development activities and our formulation and nonclinical efforts;

•suspensions or delays in the enrollment or changes to the number of subjects we decide to enroll in our ongoing clinical trials;

•the number and scope of clinical programs we decide to pursue, and the number and characteristics of any product candidates we develop or acquire;

•the timing of, and the costs involved in, obtaining regulatory approvals for any future product candidates;

•the number and characteristics of any additional product candidates we develop or acquire;

•the cost of manufacturing ZORYVE or any future product candidates and any products we successfully commercialize, including costs associated with building out our supply chain;

•the cost of commercialization activities for ZORYVE or any future product candidates that are approved for sale, including marketing, sales and distribution costs, and any discounts or rebates to obtain access;

•our ability to acquire attractive assets or businesses or to establish and maintain strategic collaborations, licensing or other arrangements and the financial terms of any such agreements that we may enter into;

•the costs related to milestone payments to AstraZeneca or any future collaborator or licensing partner, upon the achievement of predetermined milestones;

•any product liability or other lawsuits related to our products;

•the expenses needed to attract and retain skilled personnel;

•any disputes, lawsuits, or other legal proceedings related to contracts or employment matters;

•the costs involved in preparing, filing, prosecuting, maintaining, defending, and enforcing our intellectual property portfolio; and

•costs associated with any adverse market conditions or other macroeconomic factors.

Indebtedness

On December 22, 2021, we entered into a loan and security agreement (the Prior Loan Agreement) with SLR Investment Corp (SLR) and the lenders party thereto. The Prior Loan Agreement was amended and restated on January 10, 2023 (the AR Loan Agreement) to include Arcutis Canada, Inc., a corporation incorporated under the laws of the Province of Ontario, as a borrower and party. On November 1, 2023, we entered into an amendment to the AR Loan Agreement to, among others, (i) modify the financial covenant relating to minimum net product revenue, and (ii) include an additional minimum financing covenant. On August 9, 2024, we entered into a second amendment to the AR Loan Agreement (the AR Loan Agreement, as amended by the first and second amendments, the Loan Agreement) to, among others, (i) permit, during the period commencing on October 7, 2024 and ending on December 15, 2024, an optional partial prepayment of term loans outstanding, subject to a 1.0% prepayment penalty (the 2024 Partial Prepayment), (ii) add the tranche C-1 and tranche C-2 term loans, and (iii) facilitate certain other changes, including with respect to the applicable interest rate and maturity date in the event of a 2024 Partial Prepayment. The term loan facility is comprised of (i) a tranche A term loan of $75.0 million, (ii) a tranche B-1 term loan of $50.0 million, (iii) a tranche B-2 term loan of up to $75.0 million, (iv) a tranche C-1 term loan of up to $50.0 million, and (v) a tranche C-2 term loan of up to $50.0 million (collectively, the Term Loans). The tranche A term loan was funded in December 2021. With the approval of ZORYVE cream 0.3% on July 29, 2022, the tranche B term loans were funded in August 2022. As of September 30, 2025 and December 31, 2024, the aggregate principal amount outstanding under the Loan Agreement was $100.0 million.

In October 2024, we made a 2024 Partial Prepayment of $100.0 million, which reduced the aggregate principal amount outstanding under the Loan Agreement to $100.0 million. In connection with the 2024 Partial Prepayment, we are obligated to pay a prepayment penalty of $1.0 million by June 30, 2026 and a final fee of $6.95 million, representing the final fee applicable to the amount of the 2024 Partial Prepayment, on January 1, 2027. As a result of such 2024 Partial Prepayment, subject to us generating a minimum net product revenue for the trailing six (6) month period ending as of the month prior to the borrowing date equal to 80% of our projected net product revenue as set forth in its annual plan for the respective period, we will be able to draw down the tranche C-1 and tranche C-2 term loans. The tranche C-1 term loan availability will expire on March 31, 2026 and the tranche C-2 term loan availability will expire on June 30, 2026. In addition, as a result of the 2024 Partial Prepayment, (i) the maturity date of the Loan Agreement is August 1, 2029 (such date, the Maturity Date), (ii) the applicable per annum interest rate is equal to 5.95% plus the greater of (a) 2.50% per annum and (b) the one-month Secured Overnight Financing Rate (SOFR), (iii) we are no longer subject to certain cost and purchase price restrictions regarding acquisitions, and (iv) we may prepay principal amounts outstanding under the Term Loans in minimum increments of $25.0 million, subject to a prepayment premium of (a) 3.0% for any prepayment made prior to the first anniversary of the second amendment, (b) 2.0% for any prepayment made prior after the first anniversary of the second amendment and prior to the second anniversary of the second amendment, or (c) 1.0% for any prepayment made prior after the second anniversary of the second amendment and prior to the Maturity Date.

Principal amounts outstanding under the Term Loans will generally accrue interest at a floating rate equal to the applicable rate in effect from time to time, as determined by SLR on the third business day prior to the funding date of the applicable Term Loan and on the first business day of the month prior to each payment date of each Term Loan. Prior to the 2024 Partial Prepayment, the applicable rate was a per annum interest rate equal to 7.45% plus the greater of (a) 0.10% and (b) the one-month SOFR. As a result of such 2024 Partial Prepayment, the applicable interest rate will be a per annum interest rate equal to 5.95% plus the greater of (a) 2.50% and (b) the one-month SOFR. On September 30, 2025, the rate was 10.20%. The benchmark SOFR is subject to change in the event of certain events with respect to the benchmark rate. Interest payments are payable monthly following the funding of any Term Loan. Any principal amounts outstanding under the Term Loans, if not repaid or prepaid, are due and payable on August 1, 2029.

As security for the obligations under the Loan Agreement, we granted SLR, for the benefit of the lenders, a continuing security interest in substantially all of our assets, including our intellectual property, subject to certain exceptions.

If the Term Loans are accelerated due to, among others, the occurrence of a bankruptcy or insolvency event, we are required to make certain mandatory prepayments of (i) all principal amounts outstanding under the Term Loans, plus accrued and unpaid interest thereon through the prepayment date, (ii) any fees applicable by reason of such prepayment, (iii) the prepayment premiums set forth in the paragraph above, plus (iv) all other obligations that are due and payable, including expenses and interest at the Default Rate (as defined below) with respect to any past due amounts.

The Loan Agreement contains customary representations and warranties and customary affirmative and negative covenants, including, among others, requirements as to financial reporting and insurance and restrictions on our ability to dispose of our business or property, to change our line of business, to liquidate or dissolve, to enter into any change in control transaction, to merge or consolidate with any other entity or to acquire all or substantially all the capital stock or property of another entity, to incur additional indebtedness, to incur liens on our property, to pay any dividends or other distributions on capital stock other than dividends payable solely in capital stock or to redeem capital stock. We also agreed to a financial covenant whereby we must generate a minimum net product revenue equal to 75% of our projected net product revenue as set forth in our annual plan for the respective period, tested on a trailing six-month basis as of the end of each month. Each annual plan shall be approved by our board of directors and SLR, in its capacity as collateral agent, in its reasonable discretion. Any failure by us to deliver such annual plan on or before December 15 of the prior year shall be an immediate event of default.

In addition, the Loan Agreement contains customary events of default that entitle the lenders to cause any indebtedness under the Loan Agreement to become immediately due and payable, and to exercise remedies against us and the collateral securing the Term Loans. Upon the occurrence and for the duration of an event of default, an additional default interest rate (the Default Rate) equal to 4.0% per annum will apply to all obligations owed under the Loan Agreement.

In connection with the Loan Agreement, we are obligated to pay (i) a final fee equal to 6.95% of the aggregate original principal amount of the Term Loans outstanding as of the date of the second amendment, (x) with respect to any 2024 Partial Prepayment, upon the earliest to occur of (A) January 1, 2027, (B) the acceleration of all outstanding Term Loans and (C) the prepayment, or refinancing, substitution or replacement of all outstanding Term Loans, and (y) with respect to the Term Loans outstanding as of the date of the second amendment (other than 2024 Partial Prepayment), upon the earliest to occur of (A) the Maturity Date, (B) the acceleration of all outstanding Term Loans and (C) the prepayment, or refinancing, substitution or replacement of all outstanding Term Loans, (ii) a 2.00% fee with respect to tranche C term loans, due and payable on the earliest to occur of (A) the Maturity Date, (B) the acceleration of all outstanding Term Loans and (C) the prepayment, or refinancing, substitution or replacement of all outstanding Term Loans, (iii) a 2.00% extension fee with respect to tranche C term loans which remain unfunded after December 31, 2025, which shall accrue during the period commencing January 1, 2026, and ending on the earliest to occur of (A) the expiration of the tranche C term loan availability, and (B) the date on which tranche C term loan is fully drawn, and (iv) a certain amount of lenders’ expenses incurred in connection with the execution of the Loan Agreement. Additionally, in connection with the original Prior Loan Agreement, we previously had entered into an Exit Fee Agreement, whereby we agreed to pay an exit fee in the amount of 3.0% of each Term Loan funded upon (i) any change of control transaction or (ii) a revenue milestone, calculated on a trailing six-month basis. Notwithstanding the prepayment or termination of the Term Loan, the exit fee will expire 10 years from the date of the Loan Agreement.

We were in compliance with all covenants under the Loan Agreement as of September 30, 2025.
