How did the segment performance (e.g., Dermatology vs. other divisions) contribute to the quarter's results?

Based on the information you’ve provided – which consists only of the headline, a one‑sentence summary (“Arcutis today reported financial results for the quarter ended June 30, 2025, and provided a business update”) and the basic metadata (ticker, category, source, date) – there are no specific details about the performance of individual business segments (e.g., a Dermatology division versus any other divisions) included in the excerpt.

Because the segment‑level data (revenues, operating results, growth rates, or any commentary on how each segment contributed to the overall quarter) is not part of the supplied text, we cannot accurately describe:

• How much of the total revenue came from the Dermatology segment versus other lines of business.
• Whether any segment posted growth, flat performance, or declines.
• The impact of segment margins or expenses on the quarter’s net income or adjusted earnings.
• Any strategic commentary that might explain why one segment outperformed or underperformed.

What this means for you

• If you need a detailed breakdown, you will have to consult the full earnings release (usually posted on Arcutis’s investor‑relations website) or the accompanying Form 10‑Q/10‑K filing, where companies are required to present segment results in a dedicated “Operating Segments” section.
• If you are looking for a high‑level summary, the press release typically includes a management commentary that may note, for example, “Dermatology sales continued to drive growth, contributing X% of total revenue,” or “Our non‑dermatology pipeline advanced, offsetting modest declines in other areas.” Those statements would be the direct source for answering your question.
• If you only have the brief newswire snippet, the most accurate answer is: The provided excerpt does not contain any segment‑specific performance information, so we cannot determine how Dermatology versus other divisions contributed to the quarter’s results.

In short, the data necessary to evaluate segment contributions is absent from the excerpt you’ve shared. To obtain a comprehensive answer, you’ll need to retrieve the full earnings release or the detailed SEC filing for Q2 2025.
