The transactions took place at prices between $129.41 and $133.35. After the disposition, Wassenaar retains direct ownership of 12,574 Arista shares. The insider sale coincides with Arista trading at $133.50, a 43% gain over the past year, and follows a quarter that beat consensus on both EPS and revenue. Several sell-side firms raised price targets citing stronger fiscal 2026 revenue guidance and growing AI-related revenue expectations.

Key Points

  • Director Yvonne Wassenaar sold 1,815 Arista shares on February 25, 2026, for $240,380, at prices between $129.41 and $133.35.
  • Post-sale, Wassenaar directly holds 12,574 shares; the trades were executed under a Rule 10b5-1 plan adopted November 21, 2025.
  • Arista reported Q4 2025 EPS of $0.82 and revenue of $2.49 billion, both ahead of consensus; multiple brokers raised price targets citing stronger fiscal 2026 revenue guidance and AI revenue growth.

Arista Networks Inc director Yvonne Wassenaar sold 1,815 shares of the company’s common stock on February 25, 2026, producing total proceeds of $240,380. The transactions were completed in multiple trades at prices ranging from $129.41 to $133.35.

Following these dispositions, Wassenaar directly holds 12,574 shares of Arista Networks. The sales were carried out pursuant to a pre-arranged Rule 10b5-1 trading plan that Wassenaar adopted on November 21, 2025.

At the time of the filing, Arista shares were quoted at $133.50. Over the trailing 12 months the stock has appreciated about 43 percent. Separately, InvestingPro analysis cited in the company’s data indicates ANET appears overvalued relative to its Fair Value.

Despite that valuation assessment, the company’s balance sheet remains robust. Arista is reported to have a market capitalization of $167 billion and a cash-heavy position, with more cash on the balance sheet than outstanding debt.


Arista’s recent operating performance has been a central factor in investor and analyst attention. The company reported fourth-quarter 2025 earnings per share of $0.82, topping the consensus estimate of $0.76. Revenue for the quarter came in at $2.49 billion, ahead of the $2.38 billion expectation.

Following the release of results and upward revisions to fiscal 2026 revenue guidance, several brokerage firms adjusted their views. Needham raised its price target to $185 while maintaining a Buy rating. Piper Sandler lifted its target to $175 and kept an Overweight rating. Evercore ISI reiterated an Outperform rating with a $200 price target, noting an increased fiscal 2026 AI revenue target of $3.25 billion. Evercore ISI attributed part of that higher AI revenue outlook to strong demand and incremental contributions from Arista’s 7800R4 router.

These analyst actions and the company’s reported quarterly strength underline momentum in Arista’s AI-related growth and scale-out deployments, as reflected in the firms’ revised outlooks and price targets.


For investors tracking insider activity and valuation metrics, the sale by a director under a previously established trading plan arrives against a backdrop of strong quarterly results, upgraded analyst targets, and a market valuation that InvestingPro categorizes as above fair value.

Risks

  • Valuation risk: InvestingPro analysis indicates ANET appears overvalued relative to its Fair Value, which may affect investor expectations for returns.
  • Insider sale timing: The director’s sales occurred while the stock is trading significantly higher year-over-year, which may be interpreted variably by market participants.
  • Forecast dependency: Analyst target increases reference elevated fiscal 2026 AI revenue expectations and contributions from the 7800R4 router, which introduces execution risk tied to those revenue drivers.
