Fabrinet Outshines Applied Optoelectronics After Latest Earnings as Optical Stock Debate Heats Up

Fabrinet and Applied Optoelectronics are both tied to the fast-growing optical networking market, but their latest earnings reports show two very different stories. Fabrinet delivered record quarterly revenue and stronger profit growth, while Applied Optoelectronics posted rapid sales growth but remained under pressure from losses and margin challenges.

Fabrinet Delivers a Stronger Earnings Picture

Fabrinet reported third-quarter fiscal 2026 revenue of $1.21 billion, up from $871.8 million a year earlier. The company also posted GAAP net income of $125.2 million and diluted EPS of $3.45, showing solid growth across both sales and profits. Its non-GAAP EPS reached $3.72.

The company’s guidance also looked upbeat. For the fourth quarter of fiscal 2026, Fabrinet expects revenue between $1.25 billion and $1.29 billion, with non-GAAP diluted EPS projected between $3.72 and $3.87.

Applied Optoelectronics Shows Growth, But Losses Remain

Applied Optoelectronics reported first-quarter 2026 revenue of about $151.1 million, helped by demand from data center customers and high-speed optical products. However, the company still reported a GAAP net loss of $14.3 million and a non-GAAP net loss of $4.9 million.

That makes the AAOI story more mixed. The company is benefiting from AI-related network upgrades and stronger demand for 400G, 800G and next-generation optical components, but investors are still watching whether it can turn that growth into steady profit.

Why Investors May Prefer FN Over AAOI Right Now

Fabrinet appears stronger because it combines growth with profitability. Its revenue base is much larger, earnings are positive, and management’s outlook suggests continued momentum. Applied Optoelectronics may offer higher growth potential, but it also carries more risk because the company is still losing money.

For investors comparing FN and AAOI after earnings, the key difference is quality of execution. Fabrinet is already proving that demand in optical communications and AI infrastructure can translate into record revenue and rising earnings. AAOI, meanwhile, still needs to prove that its sales growth can support healthier margins and consistent profits.

Bottom Line

Fabrinet looks like the more reliable stock after the latest earnings results. Its record revenue, stronger EPS, and positive guidance make FN the cleaner choice for investors seeking exposure to optical communications, AI data center infrastructure, and advanced electronic manufacturing.

Applied Optoelectronics remains an interesting growth name, especially because of its exposure to high-speed data center products. Still, until AAOI improves margins and reaches more stable profitability, it may be better suited for investors with a higher risk tolerance.
