Fabrinet Guided Revenue Up 6% and GAAP EPS Down 10%. One Tax Line in the Reconciliation Is $0.40 of It.

Guidance & Outlook Reporter, Earnings Dispatch

Fabrinet shares closed at $476.39 on Tuesday, down $122.20 or 20.41% on the session, according to RTTNews, which reported the fall alongside the higher fourth-quarter earnings and revenue behind it and offered no explanation for the disconnect. The drop came a day after the contract manufacturer announced what its own release calls record fourth-quarter revenue, and a quarter that Needham's Ryan Koontz, writing in Benzinga, measured as ahead of the consensus he was carrying. Much of the explanation is available, and it sits in a three-line table at the bottom of the company's own guidance disclosure.

Start with the quarter. Fabrinet's August 17 release puts fiscal fourth-quarter revenue at $1,315.8 million against $909.7 million a year earlier, an increase of 44.6%. GAAP net income was $139.3 million and GAAP diluted earnings per share $3.83, up from $87.2 million and $2.42. On a non-GAAP basis, net income was $149.1 million and diluted EPS $4.10, up from $2.65. Revenue landed above the $1.25 billion to $1.29 billion the company had guided to in its May 4 third-quarter release.

The basis of the comparison matters here more than usual. Needham's Ryan Koontz, quoted by Benzinga on August 18, put the consensus at $1.276 billion of revenue and $3.81 of EPS and set the reported $4.10 against it. That is a non-GAAP figure measured against a non-GAAP estimate, which is the correct pairing. It is also worth noting that Fabrinet's GAAP EPS of $3.83 sits within two cents of that $3.81 consensus number. Anyone who lines up those two figures instead will describe a quarter that came in flat, which is not the quarter Fabrinet reported on either basis.

Now the outlook. For the first quarter of fiscal 2027, Fabrinet guided revenue to $1.375 billion to $1.425 billion. The midpoint of $1.400 billion is 6.4% above the $1,315.8 million just delivered. Non-GAAP diluted EPS is guided to $4.10 to $4.25, a midpoint of $4.175 that is 1.8% above the quarter just reported. GAAP diluted EPS is guided to $3.39 to $3.54. The midpoint of $3.465 is 9.5% below the $3.83 of GAAP EPS Fabrinet just earned.

That is the anomaly. Revenue is guided up, non-GAAP earnings are guided marginally up, and GAAP earnings are guided down by nearly a tenth. The reconciliation between the two earnings lines has to absorb the entire divergence, and the release shows exactly how it does. The bridge from the GAAP range to the non-GAAP range carries three items: share-based compensation of $0.12 within cost of revenues, share-based compensation of $0.19 within selling, general and administrative expenses, and a line the company labels as a tax provision related to Pillar Two at $0.40. The three sum to $0.71 per share.

Compare that $0.71 with recent history and the shape of the change is unmistakable. In the quarter just reported, the distance between GAAP EPS of $3.83 and non-GAAP EPS of $4.10 was $0.27. In the guidance Fabrinet issued on May 4 for that same quarter, the distance between the GAAP range of $3.48 to $3.63 and the non-GAAP range of $3.72 to $3.87 was $0.24 at both ends. The new gap of $0.71 is between two and a half and three times either. The widening from $0.27 to $0.71 is $0.44, and $0.40 of that $0.44 is the single Pillar Two line.

Fabrinet's stated non-GAAP policy, set out in the release, excludes charges arising from the implementation or application of the OECD Pillar Two global minimum tax framework, including charges that result from changes in implementing regulations. The release does not attach a country to the charge, does not give an effective tax rate for the coming quarter, and does not describe the item as limited to a single period. Koontz, per the Benzinga piece, told clients that Thailand tax legislation is expected to lift Fabrinet's rate into the high single digits; Fabrinet's manufacturing base is in Thailand, but that characterization is the analyst's, not the company's.

The distinction is not academic. Share-based compensation is a non-cash charge that virtually every hardware company excludes and every model already accounts for. A minimum-tax provision is cash that leaves the building. Both sit inside the same $0.71 bridge, and the non-GAAP EPS range of $4.10 to $4.25 is calculated as though neither existed.

Margins are the second thing the headline number does not carry. GAAP gross margin in the fourth quarter was 12.0%, against 12.2% a year earlier. Non-GAAP gross margin was 12.2%, against 12.5%. Both moved up sequentially from the third quarter's 11.9% GAAP and 12.1% non-GAAP, but both are below where they were a year ago, and that is on revenue 44.6% higher. GAAP operating income was $134.2 million and non-GAAP operating income $143.4 million.

Cash conversion is the third. For the fiscal year ended June 26, 2026, Fabrinet's cash flow statement shows $256.7 million of net cash provided by operating activities against $252.5 million spent on property, plant and equipment. That leaves roughly $4.2 million of free cash flow for a year in which GAAP net income was $473.0 million; operating cash flow was about 54% of reported GAAP earnings. The company's own supplemental free cash flow table shows the fourth quarter alone generating $55.0 million of operating cash against $91.9 million of capital expenditures, a negative $36.9 million.

The balance sheet remains unstrained. As of June 26, 2026, Fabrinet held $346.7 million of cash and equivalents, $528.3 million of short-term investments and $0.7 million of long-term restricted cash, roughly $875.7 million in total. Share repurchases for the full fiscal year came to $5.2 million.

For the fiscal year as a whole, revenue was $4.641 billion, up 36%. GAAP net income was $473.0 million and GAAP diluted EPS $13.05; non-GAAP net income was $510.9 million and non-GAAP diluted EPS $14.09, a full-year spread of $1.04 between the two bottom lines. A single guided quarter now carries $0.71 of that kind of spread on its own.

The mix commentary that moved around the market on Tuesday cannot be checked against the release, because the release does not contain it. Fabrinet's August 17 announcement gives no revenue breakdown by end market or product line. Rosenblatt's Mike Genovese, per Benzinga, described datacom revenue as down 1% sequentially on lower Nvidia sales with strength in telecom, data center interconnect, automotive and industrial; Koontz put telecom growth near 70% year over year and said management is re-segmenting its product disclosure in a way he considers more opaque. Those are analyst characterizations of information not in the public release.

Chief Executive Seamus Grady said in the release that the fourth quarter was, in his word, "exceptional," and framed the fiscal year as one of accelerating growth. Both statements are defensible against the reported figures. The guidance table underneath them describes a first quarter in which the company expects to sell more and, on the accounting basis that governs its financial statements, earn less.
