Toll Brothers, Inc. 8-K

What Happened
Toll Brothers, Inc. filed an 8-K on December 19, 2025 announcing that Michael J. Grubb, Senior Vice President and Chief Accounting Officer, notified the company he will retire as the principal accounting officer effective February 2, 2026. The company intends to appoint Erica J. Mainardi as Senior Vice President and Chief Accounting Officer effective the same date.

Key Details

• Retirement effective date: February 2, 2026; Michael J. Grubb is 61, has worked at Toll Brothers for 22 years and became Chief Accounting Officer in January 2018.
• Successor: Erica J. Mainardi, 44, will become the principal accounting officer on February 2, 2026. She joined Toll Brothers in June 2020 (Director, FP&A), was promoted to Vice President in September 2021 and has overseen Corporate Accounting.
• Background & qualifications: Mainardi is a Certified Public Accountant with a B.S. in Accounting from Saint Joseph’s University and prior roles at DuPont, BrightView, and Ernst & Young.
• Independence/disclosures: The filing states there are no arrangements or understandings related to her selection, no family relationships with company officers or directors, and no reportable related‑party transactions under Item 404(a) of Regulation S‑K.

Why It Matters
The principal accounting officer is responsible for financial reporting and accounting controls; a planned, internal promotion suggests continuity in those functions. For investors, this is a routine leadership transition rather than a financial event — there are no disclosed related‑party issues and an effective date was provided to allow an orderly handoff. Monitor upcoming SEC filings and quarterly reports for any further commentary on accounting policies or internal control changes.
