Vertical 06 · Research
Live regulatory tracker · updated Aug. 2026v1.6 · 2026-08-05
ISS, Glass Lewis, and the infrastructure behind institutional voting. This vertical tracks five layers separately — recommendations, methodology, investor dissent, alleged and verified conflicts, and the live state and federal regulatory fight over proxy-advisory services.
HEADLINE FINDING · AS OF AUGUST 5, 2026
The two firms that together advise institutional investors on the substantial majority of U.S. proxy ballots are now themselves regulatory and litigation parties — statute, federal preliminary injunction, state DTPA petition, and issuer-side DEFA14A allegations all landed in a single 11-month cycle.
Anchors: Tex. S.B. 2337 ⇒ TBOC ch. 6A; Texas AG DTPA petition (May 20, 2026); ExxonMobil DEFA14A supplements (May 12 & May 15, 2026).
Proxy advisors do not vote the shares themselves. They influence the institutional investors who do. As of May 2026, proxy advisors are themselves regulatory and litigation parties: Texas S.B. 2337 codified at TBOC ch. 6A regulates them by statute; a federal preliminary injunction enjoins enforcement against the two largest firms but only firm-specifically; the Texas Attorney General filed a parallel state DTPA action on May 20, 2026; and ExxonMobil filed two DEFA14A supplemental proxy disclosures on May 12 and May 15, 2026 alleging an undisclosed litigation-posture conflict at ISS.1
This page reports the regulatory and litigation infrastructure now. The four empirical layers — recommendation database, methodology benchmarks, dissent-rate tracker, conflict-channel registry — continue to build toward Q1 2027 cadence and are reported with status indicators.2

Four categories — different evidentiary burdens, different legal implications
A page that tracks both long-standing structural conflicts (consulting; ownership) and a newer litigation-posture conflict allegation needs a coding rule. SMU CGI uses a four-category taxonomy. Each category carries a different evidentiary…

Plain English. ISS is a registered investment adviser: within the scope of its client relationships it owes the Advisers Act’s fiduciary standard — and the Act itself gives those clients no damages action when the standard is breached.…

METHOD · STANDING RULES
V06 reports a live regulatory and litigation cycle. The rules below govern what is stated as fact, what is stated as allegation, and how every cite resolves.
RULE 01
Every statute links to statutes.capitol.texas.gov; every SEC release to sec.gov; every court filing to its docket or the agency's own server; every law-review article to its journal page or open-access PDF. Where an official public URL is unavailable, a verified repository copy is identified and labeled as such.
RULE 02
A petition, complaint, or DEFA14A supplement is evidence of what a party said; it is not proof the allegation is true. SMU CGI phrases pleading-stage materials as “Texas alleges” / “ExxonMobil alleges” / “ISS contends”.
RULE 03
Advisor vote-effect estimates are reported individually with their identification strategy — not collapsed into a single headline number. The methodological term is advisor-following vote share, not “robovote.”
RULE 04
Each release carries an explicit v#.# stamp and date in the hero. The current edition reports the state of proxy-advisor regulation as of August 5, 2026.
