On September 4, the SEC filed a rare subpoena-enforcement action in the U.S. District Court for the Eastern District of Pennsylvania against Institutional Shareholder Services (ISS) — the firm that, alongside one competitor, controls more than 90% of the U.S. proxy advisory market. The SEC's ask is narrow: force ISS to produce voting-recommendation data it has refused to hand over for four months. But the case is a clean, real-time illustration of something every registered adviser should pay attention to — not because of what ISS does, but because of what it is. ISS has been an SEC-registered investment adviser since 1997, the same status held by virtually every RIA reading this.

How a routine exam request became a federal lawsuit

The timeline in the SEC's court filing runs longer, and escalates further, than most exam disputes ever do.

March 2026
The SEC's Division of Examinations opens a routine exam of ISS — its fifth since 2006. The prior four all found deficiencies. Examiners ask for ProxyExchange data: which clients received which voting recommendations, and how those clients' shares were actually voted.
April – June 2026
ISS calls full production "unduly burdensome" and offers three client samples instead. Examiners review the samples, confirm they contain what's needed, and ask for the same data for all clients over a roughly 20-month window. ISS doesn't produce it. SEC staff follow up at least nine times.
July 6, 2026
The SEC's Division of Enforcement opens an inquiry — not into ISS's underlying business practices, but into ISS's failure to produce the requested exam information in the first place.
July 20 – 21, 2026
The SEC issues a formal order of investigation, then serves an Advisers Act Section 209(b) subpoena for three categories of documents: a client list, vote authorization agreements, and four years of ProxyExchange voting data.
August 2026
ISS produces two of the three categories, but on the voting data proposes hiring an outside "data cruncher" to fully anonymize it first — with no timeline. It then raises formal objections: confidentiality, the First Amendment, and freedom of association.
September 1 – 4, 2026
The SEC proposes a compromise on September 1; ISS rejects it on September 3. On September 4, the SEC asks a federal court to compel compliance.

Why ISS's objections didn't work — and won't work for anyone else

The SEC's brief walks through each of ISS's arguments, and the reasoning applies well beyond this one case:

How Compliers Can Help

We help firms pressure-test whether their document-production and recordkeeping systems could actually meet a real exam request — not the version everyone hopes for, but the full-scope version an examiner is entitled to ask for. Learn more about our Exam Readiness engagement.

Why this matters even if you'll never see a subpoena like this

Almost no firm will end up in federal court over an exam request. But the ladder ISS climbed — a routine document ask, treated as negotiable, that becomes a slow-walk, that draws Enforcement's attention to the non-production itself, that becomes a formal investigation — is a ladder any firm can climb by accident. The SEC's brief is blunt about the sequence: "ISS has wasted enough time and resources." Examiners read a firm's response to a document request as its own kind of disclosure about how the firm operates.

Two practical takeaways sit underneath the legal ones. First, a sample or summary offered in place of full production only works if the examiner accepts it as sufficient — once they've told you it isn't, continuing to offer variations on the same workaround reads as delay, not cooperation. Second, "we'll produce it, just anonymized" sounds like a compromise but functions as a refusal if it defeats what the examiner is actually trying to verify — worth asking, before proposing it, whether it would.

What to do right now

Sourced from the SEC's Memorandum of Law in Support of Its Application for an Order to Show Cause and an Order Compelling Compliance with Administrative Subpoena, filed September 4, 2026 in SEC v. Institutional Shareholder Services, Inc., No. 2:26-mc-00078 (E.D. Pa.). As of publication, the SEC states it has not concluded that ISS violated the federal securities laws; the underlying investigation and this enforcement action are both ongoing.
