Ambarella Inc: what insiders have been doing
Ambarella Inc, founded in 2004, is a Technology company based in Santa Clara, United States. Its directors and officers file their transactions with SEC (Form 4). In the past year (18 October 2025 to 18 October 2026), 58 filings came from 17 insiders.
Only sales appear on the open market, 29 sales in all totalling €6.0M, filed by 7 insiders. The totals do not cover 9 filings with an undisclosed amount. At €1.3M, the sale published on 28 May 2026 by Wang Feng-Ming is the largest of the period (0.038% of market cap).
For context, the typical company on the same exchange (median of 5,811 companies) published 19 filings over the same period, against 58 filings here. Over the whole record (from 2021), the tally stands at 1 purchase and 170 sales. The 10-K for the year ended 31 January 2026 shows 390.7 m USD of revenue and -75.9 m USD of net income.
Filings reach the SEC (Form 4) feed a median of 2 days after the trade. The legal deadline for a Form 4 is two business days after the transaction. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify.
For comparison within the same sector, see the insider buying recorded at Core Scientific, Inc./tx and Gitlab Inc. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.

About Ambarella Inc
Ambarella, Inc. (ticker: AMBA) is a U.S.-listed semiconductor company traded on the NASDAQ in the United States. It is best known for designing low-power edge AI and computer-vision system-on-chips (SoCs) used in applications where on-device perception, video compression, image processing, and real-time inference matter most. Founded in January 2004, Ambarella has developed a fabless model centered on chip architecture, software, and reference designs rather than owning its own fabrication plants. The company is headquartered in Santa Clara, California, in the heart of Silicon Valley. ([investor.ambarella.com](https://investor.ambarella.com/static-files/240da2ac-c79c-45de-810d-4dcc2675858d?utm_source=openai))
Ambarella’s business is organized around several end markets: automotive, security, consumer electronics, and AIoT, industrial, and robotics. Its product lineup includes the CVflow AI SoC architecture, the CV7 and CV3 families, and Oculii AI radar software. These platforms are designed to combine high-resolution video encoding/decoding, image signal processing, stereovision, neural-network acceleration, and multi-sensor fusion in highly power-efficient designs. In practical terms, that means Ambarella chips are used in ADAS cameras, in-cabin monitoring, security cameras, drones, sports cameras, robots, machine-vision systems, and other intelligent edge devices.

From a competitive standpoint, Ambarella occupies a niche but important position in edge AI semiconductors. It is not a broad-based commodity chip supplier; rather, it focuses on specialized vision processing and AI workloads at the edge, where power consumption, latency, form factor, and reliability are critical. The company states that its products are deployed across a wide range of physical edge AI use cases and that it has an installed base of more than 42 million AI SoC units. That installed base suggests meaningful product adoption across multiple generations of customer deployments. ([ambarella.com](https://www.ambarella.com/about-history/?utm_source=openai))
Geographically, Ambarella remains anchored in the United States but supports its global customer base through R&D design centers and business development offices in Asia and Europe, including Taiwan, China, Japan, and Italy. This footprint reflects the global nature of the semiconductor supply chain and the fact that many of its customers are multinational OEMs and Tier-1 suppliers. ([investor.ambarella.com](https://investor.ambarella.com/static-files/240da2ac-c79c-45de-810d-4dcc2675858d?utm_source=openai))
Recent company news has been centered on the next wave of edge AI. In early 2026, Ambarella announced a powerful 8K CV7 vision SoC and highlighted its “The Ambarella Edge: From Agentic to Physical AI” theme at Embedded World 2026. The company’s fiscal 2026 communications also emphasized continued R&D investment, expected revenue growth, and a push toward an indirect sales channel and semi-custom/custom ASIC opportunities. For investors, Ambarella stands out as a pure-play edge AI and computer-vision semiconductor name with exposure to automotive intelligence, video security, and robotics rather than general-purpose chip cycles.
