MaxLinear, Inc. (NASDAQ: MXL) designs radio frequency (RF), analog, digital, and mixed-signal integrated circuits used in connectivity, broadband infrastructure, and data center applications. Its third quarter 2026 report carries outsized weight because the company is transitioning from a history of losses toward sustained profitability, fueled by a fast-growing optical AI data center business. Coming off a sharp stock rally, this earnings release tested whether MaxLinear's operational momentum and margin expansion could justify its elevated valuation. The results also signal how quickly the Keystone PAM4 (pulse amplitude modulation, four-level) DSP platform is scaling with hyperscale customers, a key barometer for the company's long-term growth narrative.
For the third quarter of fiscal 2026, ended September 30, 2026, MaxLinear reported net revenue of $218.1 million, exceeding the analyst consensus of approximately $215 million and marking a 72% increase from $126.5 million in the prior-year period. Adjusted (non-GAAP, or non-generally accepted accounting principles) diluted earnings per share (EPS) reached $0.62, topping the consensus estimate of $0.56.
On a GAAP (generally accepted accounting principles) basis, the company swung to net income of $28.9 million, or $0.30 per diluted share, compared with a net loss of $45.5 million, or $0.52 per share, a year earlier. GAAP gross margin expanded to 58.7% from 56.9%, while non-GAAP gross margin rose to 60.0%. GAAP operating income was $30.2 million, versus an operating loss of $41.3 million in the prior-year quarter.
Infrastructure revenue grew 210% year over year, led by the volume ramp of the Keystone PAM4 DSP platform and strength across the Rushmore and Annapurna product families of 1.6T-capable optical and electrical products. For the fourth quarter, management guided revenue to $240 million to $260 million, with a midpoint of $250 million, well above the consensus of roughly $226.7 million.

Despite a top-and-bottom-line beat and above-consensus guidance, MaxLinear shares fell roughly 3% in after-hours trading, a move widely interpreted as a "sell the news" reaction after the stock appreciated approximately 270% over the trailing twelve months. The pullback suggests that much of the positive AI data center momentum had already been priced in ahead of the report.
Still, investor sentiment around MaxLinear's fundamentals remained constructive. The company's expanding non-GAAP operating margin—up to 29.5% from 12.1% a year earlier—and its raised optical data center revenue outlook for 2026 to a range of $250 million to $270 million reinforced confidence in the growth trajectory, even as near-term profit-taking weighed on the shares.
MaxLinear enters the fourth quarter with strong visibility, guided by a revenue range of $240 million to $260 million and a raised 2026 optical data center outlook of $250 million to $270 million. Management indicated that bookings visibility now extends beyond 2027, with expectations for another significant step-up in revenue next year.
Investors should monitor the pace of the Keystone PAM4 DSP ramp and the timing of initial revenue contributions from the Rushmore and Annapurna product families, which management expects to begin in 2027 before a stronger volume ramp in 2028. Continued demand signals from hyperscale data center customers will be central to sustaining the infrastructure segment's triple-digit growth.
Beyond data centers, sequential growth in broadband and connectivity categories—driven by fiber PON (passive optical network) and Wi-Fi 7 gateway deployments—offers a secondary growth lever to watch. Margin trajectory also remains key, with fourth quarter GAAP gross margin guided to 58.0% to 61.0%.
Finally, investors may track the company's balance sheet moves, including the $70 million increase to its revolving credit facility (now $200 million), as MaxLinear funds wafer prepayments and capacity to support rising demand.
