ARM

Business Context and Reporting Period

Company: Arm Holdings plc
Filing Type: Form 6-K (Report of Foreign Private Issuer)
Reporting Period: Three and six months ended September 30, 2025
Business Overview: Arm is a global leader in the semiconductor industry, licensing CPU design intellectual property (IP), graphics processors, and system IP. The company operates as a single segment, generating revenue through license fees and per-chip royalties. A significant portion of revenue is derived from related parties, primarily Arm China and SoftBank Group affiliates.

Key Financial Metrics

Margins (6 Months): Gross Margin was 97%; Operating Margin was 13%.

Material Changes vs. Prior Period

• Revenue Growth: Total revenue increased 34% year-over-year (YoY) for the quarter and 23% YoY for the six-month period. This was driven by a 120% increase in revenue from related parties (primarily Arm China and SoftBank affiliates) and a 21% increase in royalty revenue.
• Profitability: Net income surged 122% YoY for the quarter ($238M vs. $107M) and 12% YoY for the six months ($368M vs. $330M).
• Operating Expenses: Research and Development (R&D) expenses increased 36% YoY for the quarter and 35% for the six months, reflecting investments in next-generation products and headcount growth. Share-based compensation costs were a significant driver, totaling $506M for the six months.
• Non-Operating Items: Other non-operating income increased significantly due to a $131M pre-tax gain from the divestiture of the Artisan foundation IP business to Cadence Design Systems.
• Cash Flow: Operating cash flow turned strongly positive at $899M for the six months ended September 30, 2025, compared to a use of $284M in the prior year period.

Guidance, Outlook, Risks, and Unusual Items

• Unusual Items: The $131M gain on the sale of the Artisan business is a non-recurring item included in other non-operating income. Additionally, a $16.8M reversal of credit loss reserves on a loan to related party Arduino was recorded in SG&A expenses.
• Subsequent Events: In October 2025, Arm entered a definitive agreement to acquire DreamBig Semiconductor, Inc. for approximately $265M in cash, expected to close by the end of the fiscal year 2026.
• Outlook & Commentary: Management highlights strong momentum in AI workloads and an improved mix of products with higher royalty rates (e.g., Armv9). The company expects to continue investing heavily in R&D to develop compute subsystems and chiplets.
• Risks:
  • Geopolitical & Export Controls: Significant reliance on the PRC market via Arm China. Recent U.S. export control rules (BIS) regarding advanced computing chips and the "Affiliates Rule" pose risks, though implementation of the Affiliates Rule was suspended for one year in November 2025.
  • Litigation: Ongoing litigation with Qualcomm regarding the Nuvia acquisition and Architecture License Agreement. A new trial is expected in Q2 2026.
  • Concentration: Dependence on a limited number of customers and related parties for a significant portion of revenue.

Investor Verification Checklist

• Related Party Revenue: Verify the sustainability of the 120% YoY increase in revenue from related parties (Arm China/SoftBank), which now comprises 37% of total revenue.
• Export Control Impact: Monitor the status of U.S. export controls and the "Affiliates Rule" suspension to assess potential future restrictions on PRC revenue.
• Qualcomm Litigation: Track the progress of the Qualcomm lawsuit, specifically the upcoming trial in Q2 2026, as an unfavorable outcome could impact IP licensing.
• R&D Efficiency: Assess whether the 35% increase in R&D spend translates to future royalty growth, given the high fixed-cost nature of chip design.
• Divestiture Gain: Exclude the $131M one-time gain from the Artisan sale when evaluating core operating profitability trends.
