MSCI Inc. Appoints Interim Principal Accounting Officer; Interim Global Controller Named

What Happened
MSCI Inc. filed an 8-K on August 7, 2026, announcing that its Board has appointed Andrew C. Wiechmann, the Company’s Chief Financial Officer, to serve as MSCI’s principal accounting officer on an interim basis effective August 10, 2026. At the same time, Kristine Johnson was appointed interim Global Controller reporting to Mr. Wiechmann. These moves follow the previously disclosed departure of the prior Global Controller and Chief Accounting Officer (reported in an 8-K on March 31, 2026).

Key Details

• Appointment effective date: August 10, 2026.
• Interim principal accounting officer: Andrew C. Wiechmann (will continue as CFO and principal financial officer).
• Interim Global Controller: Kristine Johnson (Commercial Controller & Head of Revenue Operations since April 2025; formerly Head of External Reporting Aug 2022–Apr 2025).
• No new compensation arrangements for Mr. Wiechmann; no family relationships or transactions requiring disclosure under SEC rules were reported.

Why It Matters
This disclosure signals a temporary internal transition in MSCI’s accounting leadership while the company searches for a permanent successor. For investors, the key takeaways are continuity in financial leadership (the CFO is taking on accounting officer duties) and no immediate change in compensation or disclosed related-party transactions. These steps are administrative and intended to maintain financial reporting oversight and controls during the transition.
