With the numbers on the table, the next step is to see how this earnings profile matches up against the widely followed growth and risk narratives around Fabrinet and where those stories may need to be updated.

TTM earnings near US$421 million support growth story

• On a trailing 12 month basis, Fabrinet has generated US$4.2b of revenue and US$421.0 million of net income, with basic EPS of US$11.76, which gives you a fuller picture than just one quarter.
• Consensus narrative points to rising demand in high speed optical and data center solutions, and the current trailing figures line up with that, but investors still need to square this with risks like supply bottlenecks and customer concentration.
  • Record style telecom and DCI revenue mentioned in the consensus view is echoed in the TTM revenue moving from US$3.1b to US$4.2b across the periods provided, which fits the idea of strong demand.
  • At the same time, the consensus warning about heavy reliance on a few big customers sits next to this growth, so the TTM numbers show what is at stake if orders from those customers change.

Net margin at 9.9% and earnings quality questions

• Fabrinet is currently running at a 9.9% net margin on a trailing basis, slightly below last year’s 10%, and there is a flagged risk that a high share of earnings is non cash.
• Critics highlight in the bearish narrative that rising compliance costs, wage inflation and possible production shifts could pressure profitability, and the combination of a 9.9% margin and high non cash earnings already gives them numbers to point to.
  • The bearish view talks about margin pressure from higher operating costs and automation trends, and a margin that is not moving higher alongside strong revenue growth can be read as support for that concern.
  • Because a large part of reported earnings is flagged as non cash, anyone worried about long term earnings stability will likely focus on how much of that 9.9% margin is backed by actual cash generation rather than accounting items.

High growth expectations versus a 57.8x P/E

• The stock trades on a P/E of 57.8x, compared with 60.9x for peers and 27.3x for the broader U.S. Electronic industry, while analysts’ earnings and revenue forecasts are around 23.3% and 21.4% per year respectively.
• Bulls argue that strong reported growth, plus forecasts in the low 20% range, can justify paying this kind of multiple, and the current gap between Fabrinet’s P/E and the wider industry average shows how much weight the market is putting on that bullish view.
  • The bullish narrative leans on expected revenue growth of 28.2% a year and margin expansion to 10.0%, which lines up with the already reported 29% earnings growth and 19.2% five year trend, so the recent track record supports part of that case numerically.
  • On the other hand, with a P/E more than double the industry average and a current share price of US$679.09, anyone using the bullish scenario still has to be comfortable that these growth rates and margins can be sustained for several years to keep that multiple looking reasonable.
