SEC.gov | Request Rate Threshold Exceeded

U.S. Securities and Exchange Commission

You’ve Exceeded the SEC’s Traffic Limit

Your request rate has exceeded the SEC’s maximum allowable requests per second. Your access to SEC.gov will be limited for 10 minutes.

Current guidelines limit each user to a total of no more than 10 requests per second, regardless of the number of machines used to submit requests. To ensure that SEC.gov remains available to all users, we reserve the right to block IP addresses that submit excessive requests.

The block will be lifted automatically by waiting 10 minutes. Continuing to exceed the SEC’s maximum allowable request rate during the time-out period will extend the duration of the time-out period. To ensure fair access for all users, please reduce the rate of your requests and visit SEC.gov again after the 10 minute time-out period has passed.

For best practices on efficiently downloading information from SEC.gov, including the latest EDGAR filings, visit sec.gov/developer. You can also sign up for email updates on the SEC open data program, including best practices that make it more efficient to download data, and SEC.gov enhancements that may impact scripted downloading processes. For more information, contact opendata@sec.gov.

For more information, please see the SEC’s Web Site Privacy and Security Policy. Thank you for your interest in the U.S. Securities and Exchange Commission.

By using this site, you are agreeing to security monitoring and auditing. For security purposes, and to ensure that the public service remains available to users, this government computer system employs programs to monitor network traffic to identify unauthorized attempts to upload or change information or to otherwise cause damage, including attempts to deny service to users.

Unauthorized attempts to upload information and/or change information on any portion of this site are strictly prohibited and are subject to prosecution under the Computer Fraud and Abuse Act of 1986 and the National Information Infrastructure Protection Act of 1996 (see Title 18 U.S.C. §§ 1001 and 1030).

To ensure our website performs well for all users, the SEC monitors the frequency of requests for SEC.gov content to ensure automated searches do not impact the ability of others to access SEC.gov content. We reserve the right to block IP addresses that submit excessive requests. Current guidelines limit users to a total of no more than 10 requests per second, regardless of the number of machines used to submit requests.

If a user or application submits more than 10 requests per second, further requests from the IP address(es) may be limited for a brief period. Once the rate of requests has dropped below the threshold for 10 minutes, the user may resume accessing content on SEC.gov. This SEC practice is designed to limit excessive automated searches on SEC.gov and is not intended or expected to impact individuals browsing the SEC.gov website.

Note that this policy may change as the SEC manages SEC.gov to ensure that the website performs efficiently and remains available to all users.

Item 2.02Results of Operations and Financial Condition. Arcutis Biotherapeutics, Inc. (the “Company”) is disclosing certain preliminary financial results as of and for the three months ended September 30, 2023. While the Company has not finalized its full financial results as of and for the quarter ended September 30, 2023, the Company expects to report that for the three months ended September 30, 2023, the Company generated total revenues of approximately $38.1 million, which comprised net product revenue of approximately $8.1 million and other revenue of $30.0 million. Net product revenue was driven by demand growth for ZORYVE and sequential improvement in gross-to-net revenue compared to the prior quarter. Gross-to-net percentage for the three months ended September 30, 2023 was in the low 70 percent range. Other revenue comprised an upfront payment of $30.0 million under the Company’s License Agreement entered into with Hangzhou Zhongmei Huadong Pharmaceutical Co., Ltd., a wholly owned subsidiary of Huadong Medicine Co., Ltd., on August 10, 2023. In addition, the Company expects to report it had approximately $228.1 million of cash, cash equivalents, restricted cash and marketable securities as of September 30, 2023. During the quarter, the Company continued its selective pursuit of partners to commercialize products in the United States outside of dermatology offices, including in the primary care setting, and to develop and commercialize products in Japan and other territories outside of the United States, Greater China and Southeast Asia. In addition, the Company implemented steps to drive efficiencies and enhance its financial flexibility, including headcount reductions, to align with its previously announced pipeline reprioritization. The Company continues to evaluate and explore opportunities for further efficiencies and cost savings. These amounts are preliminary, have not been audited and are subject to change pending completion of the Company’s unaudited financial statements for the quarter ended September 30, 2023. Additional information and disclosures would be required for a more complete understanding of the Company’s financial position and results of operations as of and for the quarter ended September 30, 2023. The Company’s independent registered public accounting firm has not audited, reviewed, compiled, or applied agreed-upon procedures with respect to the preliminary financial data. Accordingly, the Company’s independent registered public accounting firm does not express an opinion or any other form of assurance with respect thereto. It is possible that the Company or its independent registered public accounting firm may identify items that require the Company to make adjustments to the financial information set forth above. Accordingly, undue reliance should not be placed on these preliminary estimates. The information contained in Item 2.02 is furnished to and not filed
