Fabrinet is the strategic bottleneck for 1.6T optical interconnects, as its proprietary 5-axis active alignment solves the sub-0.5-micron laser coupling these transceivers need. HPC revenue jumped to $86M in Q2 FY26 from $15M on 200G EML lasers for Nvidia networking. Its Thailand Building 10 expansion starts going live in July 2026, AWS and Google broaden the customer base, and it holds $961M cash with no net debt. At about 3.6x forward sales, it is not priced for hype. x.com 

Fabrinet deserves an Outperform rating and an $850 December 2026 target as an irreplaceable precision maker of 800G and 1.6T optical interconnects, AI's binding constraint. HPC revenue jumped from $15M to $86M in a quarter, new capacity serves orders in hand, and Q3 FY26 guidance of $1.15-1.20B implies about 35% growth after seven straight EPS beats. NVIDIA and Cisco concentration is a risk, but switching costs run upstream. Legacy telecom and automotive remain a drag. x.com 

Fabrinet captures AI optics volume but not pricing power, and the industry's chokepoint is moving. Revenue rose 45% to $1.316B, but gross margin fell 30bps to 12.2%, the record operating margin came from low opex, and full-year free cash flow was just $4M on $4.64B of revenue. Datacom transceivers have been flat to down for four quarters, with growth from DCI and HPC. Q1 guidance implies 4.3% less EPS per revenue dollar, versus a 2.5% rise a year earlier, more than usual seasonality. x.com 

Fabrinet trades at about 17x consensus FY2027 earnings despite 45% revenue growth last quarter. Data-center revenue rose 68% and now accounts for 51% of sales; consensus expects roughly 29% EPS growth in FY2027. Ramp delays and component shortages could defer that growth, and capacity spending still needs to produce cash flow as production scales. x.com 

Fabrinet benefits as the optical ecosystem's assembly-and-test release valve, though it is not a single chokepoint. Coherent itself said assembly and test is not a constraint for it right now, so Fabrinet's case rests on the breadth of its ongoing programs rather than on scarcity, unlike AXT or Micron. x.com 

Fabrinet's low margins suggest it lacks strong pricing power, which outweighs its growth potential and claimed moat. x.com  x.com 

Fabrinet has more exposure to Nvidia's ramp than any other public company: Nvidia is 35% of its business, and it is Nvidia's primary contract manufacturer of 1.6T optical modules, and possibly Cisco's too. SemiAnalysis estimates Nvidia's data center compute revenue will run 20% above consensus in 2H FY2027 as Rubin ramps now that earlier HBM4 issues are resolved. Given that, the stock's current level looks interesting. x.com 

Fabrinet benefits whichever laser architecture or module vendor wins, because it builds the optical modules Western brands put their names on, so assembly routes through its factories regardless. It designs nothing itself, and optical is around 75% of its business. x.com 

Fabrinet is building capacity ahead of orders, so heavy customer concentration means one program pause could turn its inventory build into a writedown. Inventories rose 76% to $1.02B and property and equipment nearly doubled to $615.1M. Demand for its AI optical modules is strong: revenue rose 45% to a record $1.32B and Q1 FY27 guidance steps up again, but gross profit grew slower than revenue, so growth is volume-led, and income tax jumped to $60.5M from $6.0M. x.com 

Fabrinet's growth is accelerating, with its fundamental Power-of-3 firmly intact. Its exceptional fiscal Q4 report showed revenue up 45% year over year and EPS up 58%, with strong momentum into FY27. x.com
