Fiserv adds Mastercard veteran Raj Seshadri to board as De Castro plans exit
Fiserv will add Raj Seshadri, Senior Strategic Advisor to the Mastercard CEO and former Chief Commercial Payments Officer at the card network, to its board of directors on 30 November 2026. Incumbent director Henrique De Castro will not stand for re-election at the 2027 annual meeting, with no disagreement cited.

Seshadri brings more than a decade of hands-on commercial payments experience spanning B2B, remittances and disbursements to board-level oversight of a company whose business spans acquiring, issuing, core banking and money movement.
Fiserv (NASDAQ: FISV) will add Raj Seshadri to its board of directors effective 30 November 2026, the payments and financial-technology group announced via GlobeNewswire on 23 October 2026, alongside a concurrent disclosure that incumbent director Henrique De Castro will not stand for re-election at the company's 2027 annual meeting of shareholders.
A Decade of Payments Experience
Seshadri joins from Mastercard, where she has spent more than a decade in senior roles. She currently serves as Senior Strategic Advisor to the Chief Executive Officer of Mastercard Inc. — a position that places her at the intersection of strategy and executive leadership at one of the world's major card networks. Prior to that advisory role, she served as Chief Commercial Payments Officer at Mastercard, where she led commercial cards, business-to-business accounts payable and receivable solutions, bill payments, remittances and disbursements.
Seshadri's background spans commercial cards, B2B payments, bill payments, remittances and disbursements — a profile that maps directly onto some of the core product lines Fiserv serves across its merchant and financial-institution client base.
That breadth of commercial payments experience makes her appointment notable in editorial terms: Fiserv's business spans acquiring, issuing, core banking and money movement, and a director with hands-on operational knowledge of B2B payment flows and disbursements adds a practitioner's perspective to board-level oversight.
Independence and Compensation Arrangements
The Fiserv board has determined that Seshadri meets the independence standard under applicable rules, as disclosed in the company's Form 8-K filed with the SEC on 23 October 2026. NASDAQ-listed companies are generally required to maintain a majority of independent directors under applicable listing rules; the Fiserv board's independence determination for Seshadri is consistent with those requirements, as disclosed in the filing.
Under the terms set out in the 8-K — summarised in public disclosures, given that direct review of the primary SEC filing was subject to access limitations — Seshadri will participate in standard non-employee director compensation arrangements and will be eligible for the director deferred compensation plan. She will also enter into a director indemnity agreement with the company.
De Castro's Planned Departure
The board transition is orderly by design. Henrique De Castro has indicated he will not seek re-election when his term comes up at the 2027 annual meeting of shareholders. The filing indicates he will serve until that 2027 annual meeting. Fiserv disclosed that De Castro's decision is not the result of any disagreement with management regarding the company's operations, policies or practices — standard regulatory language that, in practical terms, signals an uncontested succession rather than a boardroom dispute.
What the Filing Confirms — and What It Does Not
The verified record, drawn from the GlobeNewswire press release and the SEC 8-K summary, establishes the following with confidence:
- Effective date: Seshadri joins the Fiserv board on 30 November 2026.
- Current role: Senior Strategic Advisor to the CEO, Mastercard Inc.
- Prior role: Chief Commercial Payments Officer, Mastercard — covering commercial cards, B2B AP/AR, bill payments, remittances and disbursements.
- Tenure at Mastercard: More than a decade.
- Board independence: Determined by the Fiserv board under applicable rules, consistent with NASDAQ listing requirements.
- Compensation: Standard non-employee director arrangements, deferred compensation plan eligibility and a director indemnity agreement, per the 8-K.
- De Castro: Not seeking re-election at the 2027 annual shareholder meeting; departure carries no management disagreement disclosure.
Two claims that appeared in secondary coverage — that Seshadri has served on Raymond James Financial's board since 2019, and that her current Mastercard advisory role began in August 2026 — could not be independently verified from primary sources reviewed for this article and have been excluded from the reporting above pending confirmation.
Why It Matters
Board composition at large payments infrastructure groups carries operational as well as governance weight. Seshadri's commercial payments background — particularly her stewardship of B2B and disbursement products at Mastercard — gives Fiserv oversight expertise in segments that are among the faster-evolving areas of the broader payments landscape. The structured transition, with De Castro remaining through the 2027 meeting, provides continuity during the handover period.
