Ambarella Inc.'s Chief Operations Officer Lee Chan W. disposed of 10,370 ordinary shares in two trades on March 17 and March 19, 2026, generating roughly $552,213. The transactions - executed at prices between $52.77 and $54.14 per share - were performed to satisfy tax obligations stemming from the vesting of restricted stock units.

Key Points

  • Ambarella COO Lee Chan W. sold 10,370 shares across March 17 and March 19, 2026, raising about $552,213 to cover RSU-related taxes.
  • Lee also exercised options for 13,678 shares on March 17 and received 7,320 shares as an annual bonus payment on March 18 under the FY2026 Annual Bonus Plan.
  • The insider activity coincided with Ambarella’s Q4 FY2026 results - EPS of $0.13 and revenue of $100.9 million - and a Stifel price-target reduction from $100 to $90 while maintaining a Buy rating.

Ambarella Inc. (NASDAQ: AMBA) reported a series of insider transactions involving Chief Operations Officer Lee Chan W. in mid-March 2026. Lee sold a total of 10,370 ordinary shares across two separate trades, realizing approximately $552,213 in proceeds. The dispositions took place on March 17 and March 19, 2026, at prices ranging from $52.77 to $54.14 per share.

Breaking down the sales, Lee sold 6,729 shares on March 17 and followed with a sale of 3,641 shares on March 19. Company filings indicate these sales were executed to cover tax liabilities that resulted from the vesting of restricted stock units (RSUs).

Alongside the share disposals, Lee completed a set of equity-acquisition moves earlier in the same period. On March 17, Lee exercised options to acquire 13,678 ordinary shares. The next day, March 18, Lee received 7,320 shares as payment of the reporting person’s annual bonus under Ambarella’s established Fiscal Year 2026 Annual Bonus Plan.

Market context for the insider activity shows AMBA shares have declined about 33% over the past six months, though the stock was trading at $55.86 at the time of the filings. An InvestingPro analysis cited in the filings places a Fair Value for AMBA at $61.87, indicating that the platform’s assessment treats the shares as undervalued at then-current levels. The filings also point readers to a Pro Research Report on Ambarella available within the InvestingPro library of research reports.

These transactions occurred in the wake of Ambarella’s fourth-quarter fiscal 2026 earnings results. The company reported earnings per share of $0.13 for the quarter, beating the consensus estimate of $0.10. Revenue for the period was $100.9 million, slightly above the expected $100.16 million. Despite the beats, revenue declined 7.0% quarter-over-quarter, a contraction the company attributed to seasonal declines in its automotive and IoT segments.

Following the results, Stifel revised its price target on Ambarella from $100 to $90 while retaining a Buy rating on the stock. Separately, Ambarella’s board approved the Fiscal Year 2027 Annual Bonus Plan for executive officers. Under the plan, CEO Feng-Ming Wang’s target bonus is set at 100% of his annual base salary, while other executive officers have target bonuses ranging from 40% to 75% of their respective salaries.

Taken together, the filings show a cluster of standard equity actions - option exercises, RSU vesting, bonus-share payment and tax-driven share sales - that coincided with the company’s regular earnings disclosure and subsequent analyst coverage adjustments.

Risks

  • Quarterly revenue fell 7.0% sequentially due to seasonal weakness in automotive and IoT segments, highlighting demand variability risk for those end markets.
