SEC Seeks Court Order Compelling ISS to Comply With Subpoena

Key Facts

1The SEC filed its subpoena-enforcement application on September 4, 2026, in federal court in Pennsylvania.
2The subpoena was served on July 21, 2026, and sought 3 categories of records, including electronic data for a 4-year period.
3The SEC says the investigation remains fact-finding and has not established a securities-law violation.

The U.S. Securities and Exchange Commission applied on September 4, 2026, to the U.S. District Court for the Eastern District of Pennsylvania for an order compelling Institutional Shareholder Services, or ISS, to comply with an outstanding administrative subpoena.

The SEC said its Division of Examinations began examining ISS in March 2026 and requested data on voting recommendations and executed votes. After all requested information was not produced, the Enforcement Division opened an inquiry on July 6, 2026, and the Commission served the subpoena on July 21, 2026.

The examination team had requested similar reports for all clients covering July 1, 2024, through February 28, 2026. The later subpoena sought 3 categories of records, including client-identification material, vote-authorization agreements and an electronic export of ProxyExchange data for a 4-year period; the initial deadline was extended from August 4, 2026, to August 11, 2026.

According to the SEC's court memorandum, ISS agreed to produce documents responsive to Requests 1 and 2 but declined to provide Request 3 data in the format used for earlier samples and proposed anonymizing the records. In an August 24, 2026 letter, ISS cited the confidentiality of client voting strategies, possible competitive harm and First Amendment objections.

The SEC says client-specific data is needed to determine whether votes were executed according to client instructions and to assess ISS's fiduciary and recordkeeping compliance. The agency stressed that its investigation remains fact-finding and that it has not concluded that any person or entity violated federal securities laws.

ISS has been registered with the SEC as an investment adviser since 1997 and is wholly owned by Deutsche Börse. It provides institutions with research, recommendations, vote execution and recordkeeping services, making its client recommendation and voting data central to the examination described by the regulator.

The next step is for the court to consider the SEC's request and decide whether to order ISS to comply. The current proceeding seeks to enforce a subpoena and does not itself establish a securities-law violation; the official materials also provide no basis for inferring a substantiated effect on the advisory sector as a whole.
