Appointment of co-Chief Executive Officer
On December 8, 2025, the Board of Directors (the “Board”) of Klaviyo, Inc. (the “Company”) appointed Chano Fernández as the Company’s co-Chief Executive Officer, effective January 1, 2026. Mr. Fernández will serve as co-Chief Executive Officer with Andrew Bialecki, the Company’s co-founder and co-Chief Executive Officer, who was previously the sole Chief Executive Officer.
Mr. Fernández, 56, has served as a member of the Board since July 2023 and as the Company’s Interim Executive Officer since September 2025. He previously served as Co-Chief Executive Officer for Eightfold.ai, a Talent Intelligence management AI platform, from January 2024 to August 2025. Prior to that, he served as Workday’s Co-Chief Executive Officer from August 2020 to December 2022, and as a director from April 2021 to December 2022. Mr. Fernández also served as Workday’s Co-President from February 2018 to August 2020, Executive Vice President, Global Field Operations from February 2017 to February 2018, and President, EMEA and APJ from January 2014 to February 2017. Prior to joining Workday, Mr. Fernández served as Senior Vice President and Head of Innovation Sales at SAP EMEA, an enterprise application software company, from January 2007 to December 2013. He also previously served as Vice President of EMEA Sales at Infor, Inc., a founding partner and General Manager at Blue C, and a senior consultant for McKinsey & Company. Mr. Fernández holds a B.S. in Physics from the University of Salamanca and an M.B.A. from the Instituto de Empresa, both in Spain.
Other information regarding Mr. Fernández required by Items 401(b), (d), (e) and Item 404(a) of Regulation S-K was previously disclosed in the Company’s proxy statement filed with the Securities and Exchange Commission on April 23, 2025.
Velocity Global Switzerland GmbH (“Velocity”) serves as Mr. Fernández’s legal employer of record and Mr. Fernández’s services are made available to the Company through the Company’s existing service agreements with Velocity. In connection with his appointment as co-Chief Executive Officer, on December 8, 2025, Mr. Fernández’s existing employment agreement with Velocity was amended to, among other things, provide for a base salary of CHF 800,000 per annum, effective as of the date of his appointment (the “Amended Employment Agreement”). The Amended Employment Agreement has an indefinite term. Mr. Fernández also entered into a Variable Compensation Agreement with Velocity on December 8, 2025 (the “Variable Compensation Agreement”), providing for an annual target bonus of CHF 400,000.
Mr. Fernández will also receive a grant of time-based restricted stock units with an initial equity value of $33,000,000 (the “RSUs”). The RSUs will vest in twelve quarterly installments, subject to Mr. Fernández’s continued service with the Company as co-Chief Executive Officer through the applicable vesting date.
Additionally, Mr. Fernández will receive a grant of performance stock units with an initial equity value equal to $36,000,000 (the “PSUs”). The PSUs will vest in up to four tranches over a five-year measurement period, subject to the achievement of specified performance targets tied to the trading price of the Company’s Series A common stock and Mr. Fernández’s continued service with the Company as co-Chief Executive Officer through the applicable vesting date. Each tranche of PSUs will vest only if the trading price of the Company’s Series A common stock closes at or above a specified dollar value for a period of at least sixty consecutive calendar days during the applicable measurement period. The stock price targets for tranches 1 through 4 are $40.00, $55.00, $70.00, and $85.00 per share, respectively, subject to proportionate adjustment in the event of any stock split or other similar change in the Company’s capital stock.
Mr. Fernández entered into an RSU and PSU Intention Letter with the Company on December 8, 2025 in connection with the proposed awards of RSUs and PSUs described herein (the “Intention Letter”).
In the event Mr. Fernández’s service relationship is terminated by the Company without cause or by Mr. Fernández for good reason, he will be entitled to certain severance benefits consisting of a lump sum cash payment equal to thirteen times his then-current monthly base salary, and an additional lump sum cash payment equal to his then-current performance bonus target. Further, in the event Mr. Fernández’s service relationship is terminated by the Company without cause or by Mr. Fernández for good reason, in each case, within eighteen months of the commencement of his service as co-Chief Executive Officer, (i) 50% of Mr. Fernández’s then outstanding and unvested RSUs will become fully vested on the date of such termination, and (ii) to the extent that a performance target is met for any tranche of the PSUs during any applicable measurement period and the termination of Mr. Fernández’s continued service occurs following achievement of such performance target but prior to the applicable vesting date for the applicable tranche(s), the vesting of the applicable tranche(s) will occur on the date of such termination.
Additionally, in the event of a change in control of the Company, and subject to Mr. Fernández’s continued service as co-Chief Executive Officer through the closing of the change in control, (i) all of Mr. Fernández’s then outstanding and unvested RSUs will become fully vested upon the closing of the change in control, and (ii) to the extent that a performance target is met for any tranche of the PSUs during any applicable measurement period and the closing of the change in control occurs thereafter but prior to the vesting date for the applicable tranche(s), the vesting of the applicable tranche(s) shall occur on the closing of the change in control.
Mr. Fernández will remain a member of the Board and will not receive any compensation for his service on the Board while he serves as co-Chief Executive Officer. Mr. Fernández does not have a family relationship with any director or executive officer of the Company (or any person nominated or chosen by the Company to become a director or executive officer of the Company) or a direct or indirect material interest in any existing or currently proposed transaction that would require disclosure under Item 401(d) or Item 404(a) of Regulation S-K.
