Multi quarter revenue and EPS climb

• Over the last six quarters, quarterly revenue moved from US$983 million in Q3 FY 2025 to US$1.49 billion in Q4 FY 2026, while basic EPS went from US$0.24 to about US$0.29, and trailing twelve month revenue reached US$4.9 billion with EPS of US$0.85 by Q4 FY 2026.
• Consensus narrative points to custom silicon adoption and higher royalty rates as key drivers of earnings, and the data provides a mixed scorecard:
  • Trailing net income of US$904 million on US$4.9 billion of revenue implies an 18.4% margin, which is lower than the 19.8% margin cited a year earlier even as quarterly revenue has stepped up.
  • Analysts are looking for around 27.3% annual revenue growth and 36.2% annual earnings growth over the next few years, which is a much steeper climb than the roughly 15% annual earnings growth reported over the past five years, so expectations in the forecasts are pointing to acceleration from here.

Margins steady, but not expanding yet

• The trailing net profit margin of 18.4% on US$904 million of net income over US$4.9 billion of revenue is below the 19.8% level cited a year earlier, even though quarterly net income in FY 2026 ranged from US$130 million in Q1 to US$313 million in Q4.
• What stands out against the bullish view is that margin expansion in the forecasts is not yet showing up in the trailing figures:
  • Bullish analysts expect profit margins to rise from 17.1% today to 32.8% in about three years, yet the most recent twelve month margin sits at 18.4%, closer to the starting point than the target.
  • The bullish narrative talks about higher royalty rates and richer product mix lifting earnings, but the step down from 19.8% to 18.4% suggests investors may want to see clearer margin traction before leaning too heavily on those targets.

On this margin picture, bulls argue that Arm could move from high teens to over 30% profitability, so it is worth seeing how that thesis is built out in more detail. 🐂 Arm Holdings Bull Case

Rich valuation and bearish caution

• At a share price of US$302.71, Arm is trading well above the cited DCF fair value of about US$67.86 and around a 39x P/B multiple compared with an industry average near 6.3x and a peer average near 12.7x.
• Bears highlight that elevated multiples leave little room if growth or margins fall short, and the current data lines up with several of those concerns:
  • Even though analysts quote a consensus target of US$232.14, the stock price of US$302.71 already sits above that reference point, which is a gap that cautious investors often pay close attention to.
  • Share price volatility over the past three months and the margin slip from 19.8% to 18.4% provide concrete examples of how expectations can shift quickly when a stock is priced at a large premium to both peers and DCF fair value.
