In this issue, we will bring you one of the top 50 stocks in the US stock market - MaxLinear, Inc. (MXL), a communications and data center chip stock that is undergoing rapid transformation. In the wave of artificial intelligence sweeping the world, the market's spotlight has long stayed on computing chip giants such as Nvidia. However, as AI models move from "basic training" to "large-scale inference", a serious physical bottleneck has surfaced - the bottleneck of data transmission and storage.
In this issue, we will bring you one of the top 50 stocks in the US stock market - MaxLinear, Inc. (MXL), a communications and data center chip stock that is undergoing rapid transformation. In the wave of artificial intelligence sweeping the world, the market's spotlight has long stayed on computing chip giants such as Nvidia. However, as AI models move from "basic training" to "large-scale inference", a serious physical bottleneck has surfaced - the bottleneck of data transmission and storage. After a large number of GPU servers form an AI cluster, higher-speed, lower-latency data exchange is required between servers and chips, and this is inseparable from high-speed optical communications, data center interconnection, and signal processing chips. Therefore, no matter how powerful the computing power is, if the data transmission cannot keep up, the efficiency of the entire AI cluster will be greatly reduced. Under this trend, MaxLinear, a company that has mainly focused on broadband communications, radio frequency and mixed-signal chips in the past, is being repriced. Since 2026, MXL’s stock price has experienced an explosive rise, with an increase of more than 300% during the year. The company's stock price rose 76% in a single day on April 24, and hit a new high of $128.30 on June 30. The core reason driving the market's renewed focus on MXL is that the company's business structure is changing: In the past, MaxLinear was viewed more as a traditional communication chip supplier. Today, the company is transforming into an important supplier of high-speed interconnection infrastructure for AI data centers. So, what is so special about this company? Can it become the next beneficiary in the AI infrastructure investment chain? MaxLinear, Inc., founded in 2003 and headquartered in Carlsbad, California, is a leading fabless semiconductor design company dedicated to providing high-performance integrated circuits for broadband, wireless and data center networks. Through continuous technological innovation and product matrix expansion, MXL's product line has fully covered the complete ecosystem from "access network" to "core AI data center". 1. Infrastructure business: core engine of AI data center This department has surpassed traditional business and become the company's largest source of revenue and main driver of growth. MXL focuses on solving high-bandwidth, low-latency data transmission and storage bottlenecks in AI clusters. Keystone PAM4 DSP platform: focuses on 400G/800G optical transceiver module applications, and has accelerated mass production deployment in many leading hyperscale data centers (Hyperscalers) in the United States and Asia. Rushmore platform: For the next generation 1.6T optical interconnect architecture (single channel 200G), equipped with Washington TIA chips, it is currently in the stage of rapid customer verification and mass production distribution. Panther series storage acceleration SoC: The latest Panther V (PCIe Gen5) is specially designed for AI/ML inference workloads. It can offload CPU-intensive data compression, deduplication and encryption tasks, directly solving the context window expansion and memory bottleneck problems caused by agentic AI (intelligent AI). 2. Broadband access business: solid fundamentals Covers optical fiber access (PON), cable modem (Cable Modem) and optical fiber gateway chips. Affected by the destocking cycle in the post-epidemic era, the company is currently ushering in the DOCSIS 4.0 upgrade cycle and the deployment of ultra-large-scale optical fiber PON networks, providing stable cash flow support for the company. 3. Wireless connection and enterprise network services It provides Wi-Fi 7 gateway chips, 5G Open-RAN millimeter wave radio frequency single chips (such as the Sierra series, which have been deployed by many operators in North America), and Ethernet physical layer chips. Network equipment is evolving towards Wi-Fi 7 and 5G/6G, driving the value of stand-alone chips to increase. 4. Industrial and Diversified Businesses Provides high-performance analog and mixed-signal chips for industrial automation, medical and automotive electronics, maintaining steady growth. According to the company’s latest Q2 2026 financial report, MXL’s financial situation shows a very strong recovery and profit turning signal: 1. Rapid revenue rebound and structural optimization
Q2 2026 revenue: US$168.8 million, exceeding the upper limit of previous management guidance, an increase of 23% month-on-month and a year-on-year increase of 55%. The infrastructure department has become the largest revenue contributor. The revenue of this department has increased significantly by 145% year-on-year. The proportion of high-margin infrastructure products has increased, which directly led to the optimization of the overall business structure. 2. Gross profit margin remains high, and Non-GAAP profits increase significantly. Q2 2026 GAAP gross profit margin was 57.5%, and Non-GAAP gross profit margin was as high as 59.5% (a year-on-year increase of 40 basis points), firmly ranking at the forefront of the IC design industry, highlighting the technology pricing power of high value-added chips. GAAP caliber: Q2 net profit turned a profit, reaching US$1.76 million, and diluted EPS was US$0.02, compared with a loss of US$26.58 million in the same period last year. Non-GAAP caliber: Q2 net profit reached US$34.3 million, and diluted EPS was US$0.35, a surge of 1,650% compared to US$1.75 million (EPS $0.02) in the same period last year. Operating profit margin: Non-GAAP operating profit margin surged to 22.3% from 7.2% in the same period last year, fully reflecting the operating leverage effect of software/IC design companies as their revenue scale expands. 3. Strong balance sheet and cash flow As of June 30, 2026, the company held approximately US$93.73 million in cash, cash equivalents and restricted cash. Q2 operating cash flow turned positive to US$4.81 million (Q1 was -US$8.87 million), and quarterly financial flexibility and risk resistance capabilities were significantly enhanced. 4. Q3 2026 performance guidance (highly confident) Q3 net revenue is expected to be between US$210 million and US$220 million, with a median of US$215 million, which means further growth in year-on-year growth. Non-GAAP gross profit margin guidance is further increased to 58.5%-61.5%, and Non-GAAP operating expenses are controlled at US$66 million to US$71 million. 1. MXL is at the most overlooked link in the expansion of AI computing power. When the market talks about AI chips, GPUs, HBMs and custom ASICs usually first come to mind, but a truly large-scale AI cluster is not a simple stack of single chips. The more GPUs there are, the more data needs to be transmitted between GPUs, servers, and racks. If interconnect speeds can't keep up, expensive computing chips will be underutilized as they wait for data. MaxLinear's DSP, TIA and Retimer are designed to solve these high-speed transmission problems. They are located inside optical modules and high-speed connection systems. Although a single chip is not as exposed as a GPU, as the AI cluster expands from thousands of accelerators to tens of thousands or more, the number of connections and transmission rates will increase simultaneously. Therefore, MXL's growth logic does not require it to replace Nvidia. As long as the AI data center continues to expand and the connection speed continues to upgrade from 400G to 800G and 1.6T, the company will have the opportunity to increase revenue. 2. Optical data center revenue guidance has been continuously raised, indicating improved order visibility. At the beginning of 2026, management expected full-year optical data center revenue to be approximately US$100 million to US$130 million. After the first quarter financial report, the company raised its target to US$150 million to US$170 million. After the second quarter financial report, the full-year forecast was once again raised to US$210 million to US$230 million. Two major guidance increases in a short period of time usually mean that customer deployment, orders and product verification progress are better than the company originally expected. If calculated based on the guidance midpoint of US$220 million, optical data center revenue in 2026 will almost double compared to the midpoint forecast at the beginning of the year. More importantly, management expects that related products will continue to increase operating revenue after entering 2027, rather than forming a one-time high in 2026. 3. The product cycle can extend from 800G to 1.6T Many semiconductor companies will experience rapid growth for one or two quarters due to the explosion of a single product, but companies that can truly achieve higher valuations need to have a continuous product upgrade route. MXL’s current path is relatively clear:
Keystone is responsible for the current volume of 400G and 800G optical interconnections; Rushmore is targeting 200G single-channel and 1.6T optical connections; Panther V is further entering the AI storage and data processing links. This product mix means that even if Keystone's growth slows down in the future, Rushmore and Panther still have a chance to pick up the slack. As a result, the company has transformed from a connection chip company that relies on the broadband cycle to a multi-product platform covering high-speed optical communications, storage acceleration, wireless infrastructure and broadband access. 4. Revenue growth is rapidly turning into profits MXL's R&D capabilities are the source of its competitiveness, but R&D expenses also constitute high fixed costs. In the second quarter, the company's GAAP R&D expenses were approximately US$56.03 million, an increase of only approximately 19% over the same period last year; revenue during the same period increased by 55%. Non-GAAP operating expenses increased only 11% year-on-year, which was significantly lower than revenue growth. As long as revenue continues to expand in the next phase, the company does not need to increase R&D and management personnel in the same proportion, and operating profit margins are expected to further improve. This is also one of the core reasons why the market is willing to give MXL a higher valuation: not just a revenue growth story, but also a potential profit margin revaluation story. 5. The recovery of traditional businesses may form a second growth curve The market is currently focusing almost all its attention on AI optical interconnects, but MXL's broadband, PON, Wi-Fi 7 and wireless infrastructure businesses are also likely to improve in the second half of 2026 to 2027. If DOCSIS 4.0, optical fiber access and Wi-Fi 7 products enter the operator upgrade cycle, the company's traditional business will no longer be a drag, but may become the second source of growth besides the infrastructure business. That's why the third-quarter guidance's "expected growth in all four business categories" is important. It illustrates that the company's short-term growth isn't entirely driven by a single customer or optical interconnect product. As MXL is undergoing a value reshaping from "traditional semiconductor" to "high-growth AI data center target", the market has also undergone a huge change in its valuation system. Forward P/E ratio and valuation premium: The current dynamic P/E ratio of MXL is at a relatively high level, about 60-70 times, which reflects the market's high expectations for its explosive EPS growth in the next few years. Compared with competitors such as Marvell (MRVL) and Broadcom (AVGO), MXL is smaller and its market value has not yet exceeded US$10 billion. However, its infrastructure business has stronger flexibility and base advantages, which can easily produce unexpected performance surprises. Pessimistic scenario: If the broadband recovery is less than expected and the volume of AI optical chips slows down, revenue in 2027 will be approximately US$650 million, EPS $1.00, giving 14x P/E, and a target price of approximately $14. Baseline scenario: AI infrastructure ramps up in line with expectations, with revenue of approximately US$790 million in 2027 and EPS of $1.88, with a 20x P/E and a target price of approximately $38. Optimistic scenario: Keystone and Panther V are very successful, with revenue reaching $900 million in 2027, EPS $2.50, the market gives 27x P/E, and the target price can reach $67.50 ~ $97.00 (DCF model estimate). Institutions such as Benchmark, Loop Capital, Roth Capital and Needham have successively upgraded their ratings to buy from April to May 2026, indicating that Wall Street's change in attitude towards MXL has actually begun when AI optical interconnect revenue accelerated in the first quarter. Among them, Benchmark has given MXL the highest target price of $125, which means that compared with the $71.59 before press time, MXL’s potential upside is about 75%. MaxLinear is undergoing one of the most important business transformations in the company's history: a company that is re-pricing from a cyclical stock to an AI infrastructure growth stock.
In the past, it relied mainly on broadband, home networks and carrier communication cycles. Now, Keystone is helping the company enter the 800G AI optical interconnect market, Rushmore has extended its product route to 1.6T, and Panther V has further opened up the AI storage acceleration space. The biggest opportunity for MXL in the future will be to become an important chip platform for internal connections and data movement in AI data centers. The biggest risk is that the market has already paid a high price for this future in advance.
Q2 2026 revenue: US$168.8 million, exceeding the upper limit of previous management guidance, an increase of 23% month-on-month and a year-on-year increase of 55%. The infrastructure department has become the largest revenue contributor. The revenue of this department has increased significantly by 145% year-on-year.
