Growth Outlook
Keystone PAM4 DSPs are directly deployed in the expansion of 800G/1.6T AI clusters by hyperscalers (Meta, Google, Microsoft, Amazon), and the company aims for annual revenue of 100M to 130M by 2026.
Washington TIA (200G-per-lane transimpedance amplifier) is scheduled for mass production in the second half of 2026 and is targeting the 1.6T AI data center interconnect market.
The Panther V storage accelerator is an SoC that reduces AI inference memory latency, which was demonstrated at Dell Tech World 2026, and the goal is to more than double Panther revenue by 2026.
Competing in the same AI optical data center supply chain AAOI (Applied Optoelectronics)Unlike [another company], MaxLinear holds the position of supplying core DSP chips rather than finished optical modules, enabling simultaneous delivery to multiple customers.

Recent Developments
On April 23, 2026, a Q1 2026 earnings surprise was announced.
Revenue of 137.2M (+431Y) and Non-GAAP EPS of 0.22 significantly exceeded expectations, and the stock price surged by +761 after the earnings announcement.
On April 29, 2026, Loop Capital upgraded its investment rating from Hold to Buy and significantly raised its target price from $17 to $75.
Subsequently, Needham, Roth, Stifel, and others also raised their target prices.
On April 30, 2026, Washington announced the TIA (200G-per-lane, 1.6T optical module transimpedance amplifier for data centers), and mass production is scheduled for H2 2026.
In May 2026, Dell strengthened its partnership by demonstrating the Panther V at Dell Tech World 2026.
Risk Factors
1. Valuation Risk
With a market capitalization of 1 TP4 T8.3 billion and a forward P/S of 12x, the continued growth of AI is fully reflected in the price.
Significant valuation contraction may occur in the event of growth disappointment.
2. Intensified competition
Broadcom (AVGO)과 Marvel (MRVL)It ranks 1st or 2nd in the PAM4 DSP market and is dominant in capital strength and R&D capabilities.
If MXL's price competitiveness is neutralized, it may be difficult to defend market share.
3. Customer Concentration Risk
Sales may be concentrated on orders from 1 to 2 hyperscalers, and are sensitive to fluctuations in customer purchasing cycles.
4. Supply Chain and Technology Transition Risks
Due to the fabless structure, there is a high dependence on external foundries such as TSMC, so margin pressure may occur in the event of supply shortages or foundry price increases.
If the transition to next-generation architectures such as CPO (Co-Packaged Optics) accelerates, the current market based on external optical modules may shrink.
Investment Recommendation
| item | detail |
|---|---|
| Investment Opinion | Hold (Neutral) |
| Reliability | Medium |
| Investment Watch | 12 months |
| Basic target price | $105 (approx. ₩154,350) |
| Bullish target price | $138 (approx. ₩202,860) |
| Weak target price | $58 (approx. ₩85,260) |
The Q2 2026 guidance ($ 160–170M) and the surge in optical data center revenue ($ 150–170M annually) confirm that the growth momentum is substantial.
However, the stock price has already risen more than fivefold in six months, and the aggressive valuation of 49x forward P/E and 16x P/S is justified only if future growth acceleration continues.
Since the current stock price of $92.34 does not deviate significantly from the base scenario target price of $105, it is advantageous for existing holders to maintain their positions rather than making aggressive new purchases, and to approach additional purchases in installments during price corrections (in the $70–75 range).
