$MXL Earnings. Very Impressive Growth. What Does 2027 Have In Store?

Summary

MaxLinear reported strong Q2 2026 earnings with revenue of $168.8M, driven almost entirely by 800G optical DSP sales, and guided Q3 to $210-220M, far exceeding expectations. Despite the beat, the stock fell >10%, reflecting a harsh market that punishes even solid prints. The author argues revenue growth is high-quality because it comes from a qualified, volume-shipping product (Keystone) and operating margins are expanding rapidly toward the 30-35% long-term target, implying significant earnings power ahead.

•Q2 revenue of $168.8M beat the author's base case of $166-169M; infrastructure revenue landed at $85M, up 145% YoY.
•Q3 revenue guidance midpoint of $215M implies sequential growth of 27% and total growth of 57% over six months.
•All of the optical revenue growth is from the existing Keystone 800G DSP product, not from 1.6T or new receiver chips, making the guidance higher quality.
•Adjusted operating income rose from $21.8M (15.9% margin) in Q1 to $37.6M (22.3% margin) in Q2; Q3 midpoint estimate is ~$60.5M approaching 28% margin.
•Management cited share gains in 800G and order visibility extending roughly six months, with a broader customer base than feared.
•The author holds no position in MaxLinear and remains concerned about certain unspecified issues but acknowledges the print was 'really solid.'

The article provides a detailed, bullish assessment of MaxLinear's Q2 earnings beat and Q3 guide, highlighting 800G-driven revenue growth, margin expansion, and high-quality guidance from a qualified product. The stock's post-earnings decline is attributed to market sentiment, not fundamentals, suggesting potential mispricing. Risk: The author notes 'concerns' (unspecified) and the stock's volatility; 800G demand may decelerate or competition could emerge in optical DSPs.
