Fabrinet (FN) Q4 Earnings Aug 17: Two Beats, Two Selloffs, a 12% Implied Move

TL;DR

• Fabrinet reports fiscal Q4 and full-year 2026 after the close on Monday, August 17, with the call at 5:00pm ET. Management guided to revenue of $1.25-$1.29 billion and non-GAAP EPS of $3.72-$3.87.
• It has beaten and sold off twice running. February 2 brought a record quarter and a 10.22% fall the next session. May 4 brought another record and an 8.01% fall.
• Options price roughly a 12% move, per Bloomberg data compiled ahead of the print. That is wider than either of the last two reactions delivered.
• Consensus sits in the top half of the company's own guide again, near $3.85 of EPS on revenue of $1.28 billion. Clearing the number has not been the problem for this stock.
• The growth is real and lopsided. Telecom hit a record $628 million, up 55%, last quarter and datacenter interconnect rose 90% to $197 million. Datacom grew 4% and fell sequentially, held back by shortages of lasers, memory and ASICs.

The Board

What the options are asking for, against what the last two prints actually produced.

What Time Does Fabrinet Report Earnings?

Fabrinet releases fiscal Q4 and full-year 2026 results after the close on Monday, August 17, with the conference call at 5:00pm ET, per the company's own earnings advisory. The quarter ended June 26, 2026. It is the first name of any size on the week's calendar, which the week-ahead hub has in full alongside the retailers and the FOMC minutes.

Fabrinet builds optical components for other people's brands: transceivers, lasers and the datacenter interconnect hardware that moves traffic between buildings. That makes it an early, unglamorous read on AI infrastructure spending, nine days before Nvidia reports on August 26.

Down 10.22%, Then Down 8.01%

Both of those followed record quarters that cleared guidance. In February, fiscal Q2 revenue came in at $1,132.9 million, up 35.9%, with non-GAAP EPS of $3.36 beating consensus by 5.33%. The stock fell 10.22% the next session. On May 4, fiscal Q3 revenue hit $1,214.3 million, up 39.3% year over year, non-GAAP EPS of $3.72 cleared consensus by $0.14, and the stock fell 8.01%.

So the printed quarter has stopped being the event. What moved the stock both times was the guide that came with it, landing on a share price that had already paid for the good outcome.

That pattern is not confined to this ticker. Coherent reported on August 12 with non-GAAP EPS of $1.74, above the top of its own $1.52-$1.72 range, and guided fiscal Q1 revenue to $2.2-$2.4 billion. Shares traded down 3.55% after hours. Three optical prints in a row, three beats, three negative reactions.

Where the Growth Actually Is

Last quarter's $1,214.3 million split unevenly. Telecom did $628 million, a record, up 55% year over year. Datacenter interconnect did $197 million, up 90% year over year and 38% sequentially, which management called staggering on the call and is the fastest-growing line in the business.

Datacom is the laggard, at $260 million, up 4% year over year and down 6% sequentially. Management said demand during the quarter far exceeded what it could ship, blaming shortages of lasers, memory and ASICs. That is a supply problem rather than a demand problem, and it connects directly to the memory shortage this site has been tracking all summer.

Two 800G datacom transceiver programs with a hyperscale customer were qualified last quarter, with the initial ramp starting in the quarter being reported Monday. Whether that ramp landed on schedule is the single most useful thing the call can tell anyone.

What I Am Watching

The fiscal Q1 2027 guide, and nothing else with the same weight. Consensus of roughly $3.85 against a $3.72-$3.87 range means a beat on the reported quarter is close to the base case, and two prints have now shown that a beat alone does not hold the stock up.

On valuation, shares closed Friday's session at $570.22, about 24% below the 52-week high of $748.89 set on May 14 and still more than double the $272.49 low from last August. Stockanalysis.com puts the forward P/E at 34.7 on a $20.4 billion market cap. Needham's Ryan Koontz kept a Buy on July 22 while cutting his target from $800 to $650; Barclays' Tim Long raised his to $702 on May 6 with an Overweight. Both are sell-side targets rather than this site's, and neither carries a stated horizon beyond the usual twelve months.

I think the business is compounding faster than the multiple now assumes, and I also think Monday is a poor moment to express that.

The Options Angle

The specific thing worth pricing here is the gap between what the chain is asking and what this name has recently done. About 12% of spot is roughly $68 on a $570.22 share, which needs a settle outside $501.79 or $638.65 to pay. February produced 10.22% and May produced 8.01%. Both would have lost money for a straddle buyer at this price.

That cuts against the calibration lesson this site took out of July, when realised moves ran well above implied across Roblox, SanDisk and Reddit. In Fabrinet specifically, implied has beaten realised twice running, and the July reflex does not transfer to a name with its own record. I could not source live chain prices this evening, so the rows below are quoted against the implied move rather than a dealt premium.

Trade log

#	Stance	Structure	Strikes and expiry	Cost or credit	Spot at writing	Implied move	Conviction	Breakeven
1	Pass	Long straddle	At-the-money, Aug 21 weekly	~12% of spot, no live quote sourced	$570.22	±12.0%	6/10	needs a settle below $501.79 or above $638.65
2	Pass	Long common through the print	n/a, shares	n/a	$570.22	±12.0%	7/10	FN holding $570.22 into August 18
3	Bullish, pending	Long common entered after the reaction	n/a, 12-month horizon	no entry until the print clears	$570.22	±12.0%	5/10	entry struck on the August 18 close

Row 3 is deliberately opposed to row 2 and scored over a different window: the pass is on carrying the event, the long is on owning the business once the event has repriced it. Every row above is logged in the Track Record ledger and will be graded against the settled close rather than the first after-hours tick.

The One-Line Read

Fabrinet is growing 40% and has fallen on both of its last two beats, so the event Monday is the fiscal 2027 guide, not the quarter. At 12%, the chain is asking more than this name has recently delivered.
