Appointment of Chief Financial Officer; Departure of Chief Financial Officer
On December 1, 20
23, Arista Networks, Inc. (the "Company") announced the appointment of Chantelle Breithaupt to serve as the Company's Senior Vice President, Chief Financial Officer. Ms. Breithaupt will join the Company on or about January 4, 2024 and will formally assume the duties of the Company's principal financial officer and principal accounting officer immediately following the filing of the Company's Form 10-K for the fiscal year ending December 31, 2023.
Ms. Breithaupt, age 51, has served as Senior Vice President and Chief Financial Officer of Aspen Technology from March 2021 to present. Prior to Aspen Technology, Chantelle spent 7 years with Cisco Systems Inc. She held multiple leadership positions at Cisco, most recently as Senior Vice President, Finance from January 2021 to March 2021, Vice President of Finance – Customer Experience/Services from August 2018 to January 2021, Vice President – Finance, Americas from October 2017 to August 2018 and Senior Director – Operational Finance from April 2014 to August 2015. Before Cisco, Chantelle worked with GE for
17 years,
where she held progressive, executive global finance roles. Ms. Breithaupt holds an Honors Business Administration degree from Wilfrid Laurier University (Canada).
The Company entered into offer letters with Ms. Breithaupt to memorialize her employment (collectively, the "Letter Agreement"). Pursuant to the terms of the Letter Agreement, Ms. Breithaupt will commence employment on or about January 4, 2024 in the temporary role as Senior Vice President, Chief of Staff.
In this role, Ms. Breithaupt will receive an annual base salary of $315,000. Subject to necessary corporate approvals, Ms. Breithaupt will receive a grant of restricted stock units covering shares of the Company common stock having a value of $10 million ("RSUs") under the Company's 2014 Equity Incentive Plan (the "Plan"). Such RSUs will vest as to 25% on the Company's first vesting date after the one-year anniversary of the vesting commencement date, and then 1/16 quarterly thereafter over a total of approximately four years, subject to Ms. Breithaupt's continued service to the Company through each vesting date. Further, immediately following the filing of the Company's Form 10-K for the fiscal year ending December 31, 2023, subject to necessary corporate approvals, Ms. Breithaupt will be appointed the Company's Chief Financial Officer. In this role, Ms. Breithaupt's salary will remain the same and she will also be eligible to participate in the Company's corporate bonus program for executive officers. Additionally, subject to necessary corporate approvals, Ms. Breithaupt will receive a grant of performance-based restricted stock units covering shares of the Company's common stock having a value of $2 million ("PSUs") under the Plan. The PSUs will cover four 1-year performance periods. For 2024, the performance targets for the PSUs will be the same as the Company's other executive officers other than the Chief Executive Officer. Ms. Breithaupt will receive a relocation bonus of $50,000 once she commences working full-time at the Company's corporate headquarters.
In addition, in connection with the appointment as Chief Financial Officer, the Company will enter into a severance agreement with Ms. Breithaupt. The severance agreement provides that if Ms. Breithaupt's employment is involuntarily terminated other than for "cause" (as defined in the severance agreement) or if Ms. Breithaupt resigns for "good reason" (as defined in the severance agreement) then, subject to her execution of a release of claims, Ms. Breithaupt will receive continuing payments of her base salary for 12 months and accelerated vesting of time-based equity awards that would have vested had Ms. Breithaupt remained employment with us for 12 months following her termination of employment date. If the qualified termination of employment occurred during the period beginning on, and for 12 months following a change in control, then the equity acceleration benefit would be 50% of the then-unvested equity awards, if greater than the acceleration benefit described in the previous sentence.
The Letter Agreement and severance agreement between Ms. Breithaupt and the Company are attached as Exhibits 10.1 and 10.2, respectively, to this Current Report and is incorporated herein by reference.
There are no family relationships between Ms. Breithaupt and any director or executive officer of the Company, and the Company has not entered into any transactions with Ms. Breithaupt that are reportable pursuant to Item 404(a) of Regulation S-K. Except as described above, there are no arrangements or understandings between Ms. Breithaupt and any other persons pursuant to which she will be appointed as an executive officer of the Company.
