Company profile
researched Aug 2026Aquantia Corp. was incorporated in Delaware on January 27, 2004. Co-founder Dr. Phil Delansay had been an entrepreneur-in-residence at Greylock Partners in 2003 immediately before founding the company, and served as Aquantia's first President and CEO from inception until January 2009. Co-founder Dr. Ramin Farjadrad, a Stanford-trained mixed-signal IC architect who had earlier co-founded Velio Communications (acquired by Rambus/LSI Logic), served as Aquantia's first Chief Architect. Faraj Aalaei, previously a co-founder/CEO of Centillium Communications, joined as President and CEO in January 2009 and became Chairman in October 2016, leading the company through its IPO and eventual sale.
Aquantia built its business around high-speed Ethernet PHY (physical layer) chips, initially focused on 10GBASE-T for data-center servers -- it shipped what it described as the industry's first integrated 10GBASE-T MAC/PHY for servers in 2013. In 2012 it developed AQrate technology, which became the technical baseline for the IEEE 802.3bz standard (2.5GBASE-T/5GBASE-T, ratified September 2016), and in 2014 it co-founded the NBASE-T Alliance with Cisco and others to promote multi-gigabit Ethernet for enterprise wired/wireless access networks. It later developed QuantumStream, a proprietary technology for transporting data at up to 100Gbps over a single copper lane for data-center interconnects, and pushed into the automotive market with Multi-Gig Ethernet PHYs aimed at ADAS and autonomous-vehicle networking. Aquantia was named EE Times/EDN's 'Company of the Year' at the 2014 Creativity in Electronics awards and was ranked the fastest-growing North American semiconductor company on the Deloitte Technology Fast 500 in 2014, 2015 and 2016. In September 2012, Aquantia acquired 10GBASE-T assets from PLX Technology, its only known acquisition.
Aquantia financed itself primarily through venture rounds of convertible preferred stock (Series A through H) plus venture debt (from Pinnacle Ventures and later Hercules Technology Growth Capital). Per its 2017 IPO prospectus, the company raised an aggregate of $199.5 million in net proceeds from convertible preferred stock since inception through June 30, 2017. Disclosed related-party financings show Series G (~$20 million, closed January-July 2014, at $1.4314298/share) with participation from GLOBALFOUNDRIES, Joint Stock Company RUSNANO, New Enterprise Associates 13 L.P., entities affiliated with Pinnacle Ventures, entities affiliated with Greylock Partners, and entities affiliated with Lightspeed Venture Partners; and Series H (~$37 million, closed March-July 2015, at the same per-share price) with GLOBALFOUNDRIES ($20M) and Walden Riverwood Ventures, L.P. ($5M) as the disclosed related-party participants (GLOBALFOUNDRIES also held a warrant for further Series H shares, exercised in full May 5, 2017). Earlier rounds (Series A, B, C-1, D, E, F) are referenced in the cap table and stock-compensation disclosures but their individual dates/amounts/investor lists are not broken out in the prospectus. Notably, Greylock Partners (via Greylock XI Limited Partnership, Greylock XI-A Limited Partnership, and Greylock XI Principals LLC), Lightspeed, and NEA had each held more than 5% of Aquantia's capital stock at earlier points, but on August 25, 2017 all three sold their entire remaining stakes (a combined 6,730,007 preferred shares, ~26% of pro-forma common stock) for approximately $58.0 million in a private secondary sale to a consortium that included Walden International, Paxion Capital, Aquan LLC, and Aquantia insiders (CEO Faraj Aalaei, CFO Mark Voll, and director Sam Srinivasan) -- a transaction that also gave Paxion Capital the right to designate a board member. As a result, Greylock held no shares of Aquantia at the time of its IPO roughly ten weeks later.
Business model
Fabless semiconductor company; designed high-speed Ethernet PHY/transceiver ICs and licensed/sold them to OEMs and networking-equipment makers, who integrated them into servers, switches, access points, and (later) automotive ADAS/infotainment systems.
Direct sale of semiconductor chips (ASICs/ASSPs) to OEM customers and, in some cases, licensing of IP/technology (e.g., an IP licensing agreement with GLOBALFOUNDRIES); highly concentrated customer base with Intel alone accounting for roughly 65-78% of annual revenue in 2014-2017 (Aquantia's PHY chips shipped attached to Intel NICs/controllers).

Profile (continued)
Aquantia priced its IPO at $9.00 per share on November 2, 2017, offering 6,818,000 shares (total offering size $61.36 million; net proceeds to the company approximately $57.1 million before the underwriters' over-allotment option), and began trading on the NYSE under ticker 'AQ' on/around November 3, 2017; shares were delivered November 7, 2017. Lead underwriters were Morgan Stanley, Barclays and Deutsche Bank Securities, with Needham & Company and Raymond James as additional underwriters. At IPO, greater-than-5% stockholders were Aquan LLC (CEO-affiliated holding entity), Joint Stock Company RUSNANO (Russian state fund), entities affiliated with Pinnacle Ventures, entities affiliated with Walden International, GLOBALFOUNDRIES U.S. Inc., and Paxion Partners, LP -- Greylock was not among them, having exited via the pre-IPO secondary sale described above.
As a public company Aquantia reported revenue of $24.5 million (2014), $80.8 million (2015), and $86.7 million (2016), with Intel representing an outsized share of revenue (roughly 65-78% in various years) because Aquantia's PHY chips shipped alongside Intel network controllers -- a customer-concentration risk repeatedly flagged in its filings. Its named board of directors and officers around the IPO/pre-acquisition period included Faraj Aalaei (Chairman/President/CEO), Mark Voll (CFO, since Jan. 2016; predecessor CFO Linda Reddick moved to SVP Finance), Kamal Dalmia (SVP Sales & Marketing), Ramin Shirani (SVP Engineering & director), and non-employee directors Dmitry Akhanov (Rusnano USA CEO, director since April 2013), Bami Bastani (GLOBALFOUNDRIES SVP RF, ex-CEO of Meru Networks and Trident Microsystems, director since June 2016), Geoffrey G. Ribar (former Cadence Design Systems CFO, director since Sept. 2017), Ken Pelowski (founder/Managing Partner of Pinnacle Ventures, director since April 2013), Sam Srinivasan (Inphi board member, former Cirrus Logic CFO, director since Dec. 2015), Anders Swahn (former Alion Energy/Nicira/PicoChip/Abrizio executive, director since Aug. 2008), and Lip-Bu Tan (Walden International founder/Chairman and Cadence Design Systems President/CEO, lead independent director since Oct. 2016, director since March 2015).
On May 6, 2019, Aquantia entered into an Agreement and Plan of Merger with Marvell Technology Group Ltd. (via merger subsidiary Antigua Acquisition Corp.), agreeing to be acquired for $13.25 per share in cash -- an all-cash equity value of roughly $476 million based on the ~35.97 million shares outstanding as of the June 2019 proxy record date (commonly reported in press coverage as an enterprise value of approximately $452 million, likely net of Aquantia's cash on hand; the exact net-of-cash figure could not be independently re-verified from primary sources in this research session, but the $13.25/share price and the ~36M share count are both confirmed directly from SEC filings). Aquantia's proxy (DEFM14A, filed June 10, 2019) disclosed 'Supporting Stockholders' who agreed to vote in favor of the merger, representing about 13.4% of shares: WRV II, L.P. and Walden Riverwood Venture, L.P. (Walden International-affiliated funds), Joint Stock Company 'RUSNANO', CEO Faraj Aalaei, and lead independent director Lip-Bu Tan, plus certain of their trusts -- notably, Greylock is not among the supporting/major stockholders at this stage either, consistent with its 2017 exit. The deal closed on September 19, 2019 (Aquantia's stock was delisted from the NYSE and the company became a wholly owned subsidiary of Marvell). Marvell's stated strategic rationale was to combine Aquantia's Ethernet PHYs with Marvell's switch and processor portfolio into what CEO Matt Murphy called 'an unparalleled networking platform,' spanning enterprise, data-center and automotive (autonomous-vehicle) customers. Aquantia's former CEO, Faraj Aalaei, joined Marvell in a senior leadership role after the close. The Aquantia brand was subsequently phased out and folded into Marvell's networking/connectivity product lines.
In Aquantia's own IPO prospectus, it named its principal competitors in the enterprise and data-center markets as Broadcom and Marvell -- meaning Marvell went from being a disclosed competitor to Aquantia's eventual acquirer within about 18 months of the IPO.
