The money is committed now; the walls are not. [Fabrinet](https://theinference.org/markets/companies/fabrinet), the Thailand-based manufacturer that assembles the lasers and optics moving data inside AI data centers, [reported fiscal first-quarter 2027 revenue of $1.474 billion on November 2](https://www.druckfin.com/en/articles/fabrinet-lifts-revenue-capacity-target-to-16-billion-as-growth-hits-51-its-faste-20261102), up 51% year over year and above its own guidance [1][3]. Record non-GAAP earnings per share of $4.34 beat the $4.31 estimate, and [the stock rose 12% after the close](https://www.quiverquant.com/news/FABRINET+%28%24FN%29+Releases+Q1+2027+Earnings%2C+Stock+Rises) [1][3]. Data center revenue grew 78% to $777 million, now 53% of the total [1]. That is the seventh straight quarter of accelerating growth. But the quarter's most consequential number was not revenue. It was concrete. ## Building 11 got bigger before the walls went up CEO [Seamus Grady](https://theinference.org/markets/people/seamus-grady) said construction of Building 11 at the Chonburi campus begins as soon as Building 10 is completed in January [1]. The building is now sized at about 1.5 million square feet and roughly $3 billion of revenue capacity, up from the $2.1 billion management previously cited, because denser products lift revenue per square foot [1]. The new arithmetic: capacity ended fiscal 2026 near $5.8 billion, should enter 2027 around $10 billion, reaches $13 billion with Building 11, and a potential Building 12 takes the ceiling to $16 billion [1]. Management had previously framed the full build-out at about $14 billion [1]. *Chart: **Fabrinet's build-out ceiling rose from about $14 billion to $16 billion** Bars showing Fabrinet revenue capacity stepping from $5.8 billion at the end of fiscal 2026 to about $10 billion entering 2027, $13 billion with Building 11 and $16 billion with a potential Building 12; the three forward bars are estimates.* *Revenue capacity ends fiscal 2026 near $5.8 billion; management's stepping targets take it to roughly $16 billion if a potential Building 12 is built. Figures for 2027 onward are management projections. Source: Druckfin, from Fabrinet's November 2 earnings call. [1]* ## The bill lands before the capacity does Free cash flow was negative $137 million [1]. Capital spending hit $159 million, including a $77 million purchase of the Santa Clara campus, cash fell $119 million to $757 million, and the company borrowed about $75 million [1]. Building 11 takes roughly 18 months to build and comes online around mid-2028, and Grady said the company is already "actively looking" for land and existing factories to bridge the gap [1]. Meanwhile the December-quarter guide calls for $1.6 to $1.65 billion of revenue, 43% growth at the midpoint [1]. *Chart: **Revenue growth has accelerated seven quarters running, reaching 51%** Line chart of Fabrinet quarterly revenue in billions of dollars, rising steadily from $0.713 billion in the quarter ended December 2023 to $1.474 billion in the quarter ended September 2026, with the curve steepening in the final four quarters.* *Revenue growth has accelerated seven quarters running, reaching 51% [5]* ## The Street cut the target while keeping the faith [Barclays](https://theinference.org/markets/companies/barclays) kept its Overweight rating but [cut its price target 33%, to $496 from $739](https://www.tradingview.com/news/tradingview:845ba09edc694:0-barclays-maintains-fabrinet-at-overweight-lowers-price-target-to-496-from-739/), still implying 36.5% upside from the November 3 close of $363.33 [2]. Targets across the last five analyst notes run $364 to $600 [2]. That spread is the debate in one line: nobody doubts the growth; the argument is what multiple a business with negative free cash flow and a 2028 capacity date deserves [2]. ## The customer list consolidated underneath the quarter Hours before the call, [Marvell](https://theinference.org/markets/companies/marvell) [agreed to buy Lumentum](https://247wallst.com/investing/2026/11/02/marvell-slides-3-lumentum-drops-6-on-115-billion-all-stock-merger-deal-coherent-climbs-2/), both Fabrinet customers, in a $115 billion all-stock deal expected to close in the first half of 2028 [4]. Grady had seen no terms and leaned on precedent: past optical consolidation, [Lumentum](https://theinference.org/markets/companies/lumentum) with NeoPhotonics among them, ultimately grew Fabrinet's business with the combined entity [1]. Precedent is not assurance. When a customer base of a few giants merges, the merged giant negotiates as one. The Inference's [November 2 preview](https://theinference.org/article/fabrinet-reports-tonight-on-1-4-billion-as-innolight-and-eoptolink-blame-floods-not-fading-ai-orders) asked whether supply, not demand, would cap this quarter; components are still "in tight supply across the board," and Grady says Fabrinet could ship more if it had more parts [1]. ## What decides it from here Watch whether revenue keeps compounding faster than the walls rise. If the roughly $10 billion of expected 2027 capacity fills before Building 11 opens in mid-2028, the "actively looking" hunt for interim space turns from caution into urgency [1]. Demand "as far as the eye can see" is management's claim [1]; negative $137 million is on the page. ## Takeaway Fabrinet's growth is real and accelerating, but the bet investors must judge is $137 million of negative free cash flow against capacity that does not open until mid-2028. ## Sources 1.
