MaxLinear Sees 76% Q4 Infrastructure Surge, Authorizes $20M Buybacks
MaxLinear reported fourth-quarter revenue of $136.4 million, up 8% sequentially and 48% year-over-year, with GAAP and non-GAAP gross margins of 57.6% and 59.6% and $10.4 million in operating cash flow. CEO Kishore Seendripu highlighted 76% Q4 infrastructure growth, $20 million in share buybacks, and $100M–$130M 2026 Keystone DSP revenue guidance.
1. Inflection Year and Full-Year Growth
On its Q4 2025 earnings call, MaxLinear’s CEO Kishore Seendripu declared 2025 an “inflection year,” driven by full-year revenue growth of 30%, non-GAAP profitability and positive free cash flow ahead of plan. Fiscal 2025 net revenue reached $467.6 million, up from $359.7 million in 2024, while non-GAAP gross margin held at 59.3%, only slightly below 59.7% the prior year. The company posted non-GAAP income from operations equal to 9% of net revenue, versus a non-GAAP loss of 19% in 2024, and generated $19.6 million in operating cash flow compared with a $45.3 million cash burn a year earlier.
2. Q4 Segment Performance and Profitability
In Q4 2025, MaxLinear delivered $136.4 million in revenue, up 48% year-over-year and 8% sequentially. Infrastructure products drove $47 million, broadband $58 million, connectivity $18 million and industrial multi-market $14 million. GAAP gross margin expanded to 57.6%, while non-GAAP gross margin improved to 59.6%, with the 2.0-point gap primarily due to $2.6 million of acquisition-related intangible amortization. GAAP operating expenses were $93.5 million (68% of revenue), compared to non-GAAP OpEx of $59.2 million (43%), with $28.1 million in stock-based compensation and $6 million in acquisition costs accounting for the difference. Non-GAAP operating income equaled 16% of net revenue, versus an 11% GAAP loss from operations.
3. Cash Flow, Buybacks and Balance Sheet Strength
MaxLinear generated $10.4 million of net cash flow from operations in Q4, up slightly from $10.1 million in Q3, and repurchased $20 million of common stock under a $75 million board-authorized buyback program. Total cash, cash equivalents and restricted cash stood at $101.4 million at quarter end. Working capital improved: days sales outstanding declined to 31 days and inventory decreased by $8 million sequentially, reducing inventory days to 130. Management noted that buyback activity reflects confidence in sustained cash flow improvement and revenue stability.
4. 2026 Outlook and Segment Drivers
For Q1 2026, MaxLinear guided revenue of $130 million to $140 million, with infrastructure expected to grow sequentially while broadband, connectivity and industrial multi-market face typical seasonal declines. GAAP gross margin is projected at 56%–59% and non-GAAP at 58%–61%. GAAP operating expenses are forecast at $85 million to $90 million and non-GAAP OpEx at $58 million to $64 million. Longer term, management expects infrastructure to become the largest revenue category, with Keystone optical DSPs driving $100 million to $130 million in 2026 and Panther accelerator revenue at least doubling year-over-year, positioning gross margin to exit the year “starting with a six.” Basic and diluted share counts are projected at approximately 88 million and 91 million, respectively.
