Cisco Systems (CSCO) is the clearest knot in Marvell Technology’s (MRVL) disclosed relationship map. Marvell places Cisco in three different categories: customer, strategic partner, and direct competitor. That is less a tidy supply chain than a semiconductor small town, where companies buy from one another, partner with one another, and then compete for the next socket.
Marvell’s own filing describes the industry trend that puts Cisco in the middle of the map.
"In addition, there has been a trend toward customer consolidation in the semiconductor industry through business combinations, including mergers, asset acquisitions and strategic partnerships (for example, Cisco acquired Acacia Communications in 2021)."
(Marvell Technology, Inc. (MRVL), SEC filing, March 11, 2026)
The same sentence is used for Marvell’s disclosed partner relationships with Acacia Communications (ACTG) and Cisco. Acacia is now part of Cisco, so the filing’s relationship web includes both the acquired company and the buyer, at least in the language Marvell uses.
Cisco also appears in Marvell’s competitor list, alongside Broadcom (AVGO), Qualcomm (QCOM), Advanced Micro Devices (AMD), Astera Labs (ALAB), and Credo Technology Group (CRDO).
"Table of Contents Companies that compete directly with our businesses include, but are not limited to, Advanced Micro Devices, Inc. (\"AMD\"), Alchip Technologies (\"Alchip\"), Astera Labs, Inc., Ayar Labs, Inc. (\"Ayar Labs\"), Broadcom Inc. (\"Broadcom\"), Cisco…"
(Marvell Technology, Inc. (MRVL), SEC filing, March 11, 2026)
The filing therefore names Cisco as more than a buyer. It is also part of the competitive field Marvell says it faces. Marvell’s customer disclosures also cite Qualcomm and Broadcom in the context of consolidation across the semiconductor industry, while both companies appear in the direct-competitor list. The categories overlap by design, or at least by filing language.
The newer, more specific partnership is with NVIDIA (NVDA). Marvell says the two companies announced a strategic partnership around custom XPUs and networking for NVIDIA’s artificial-intelligence infrastructure ecosystem.
"During the first quarter of fiscal 2027, Marvell and NVIDIA Corporation (“NVIDIA”) announced a strategic partnership to connect our custom XPUs and compatible scale-up networking with NVIDIA’s AI infrastructure ecosystem."
(Marvell Technology, Inc. (MRVL), SEC filing, May 28, 2026)
That is the cleanest forward-looking relationship in the set, stated as an announced partnership rather than an industry example. The filing does not describe NVIDIA as one of Marvell’s direct competitors.
On the other side of the map, Infineon Technologies (IFNNY) is tied to Marvell through a completed transaction, not an ongoing operating partnership. Marvell says it sold its automotive Ethernet business to Infineon for $2.5 billion in cash.
"Recent Developments On August 14, 2025, we completed the sale of our automotive ethernet business to Infineon Technologies AG for $2.5 billion in cash."
(Marvell Technology, Inc. (MRVL), SEC filing, March 11, 2026)
Marvell’s filings also preserve the older Inphi Corporation (INAC) connection through the 2020 merger agreement. The relationship map consequently includes a major divestiture, an older merger agreement, and a new AI infrastructure partnership, alongside the usual industry tangle of buyers and rivals.
The supplier side is thinner, and the receipts deserve that qualification. Marvell’s relationship data names Micron Technology (MU), but the cited filing language discusses China’s treatment of Micron as an “unreliable supplier,” not a procurement agreement between Micron and Marvell. The disclosed map is strongest on overlap among customers, partners, and competitors, rather than on a neat list of vendors.
Other companies’ filings add more edges: MaxLinear (MXL), Credo, Astera Labs, AMD, MACOM Technology Solutions (MTSI), Rambus (RMBS), and Fortinet (FTNT) name Marvell as either a competitor or supplier. In this industry, the org chart is apparently optional.
These are relationships disclosed in SEC filings, mapped by jodie’s analytics. This is not investment advice.
