Amcor plc Appoints PwC US as Auditor; PwC Switzerland Resigns

What Happened

• Amcor plc announced that on August 11, 2026 its Board, following the Audit Committee's recommendation, accepted the resignation of PricewaterhouseCoopers AG, Switzerland (PwC Switzerland) and appointed PricewaterhouseCoopers LLP, United States (PwC US) as the Company’s independent registered public accounting firm. Both changes are effective August 14, 2026 after Amcor filed its Form 10-K for the fiscal year ended June 30, 2026. PwC US will begin work in the transition fiscal year ending December 31, 2026, including the interim review for the period ending September 30, 2026.

Key Details

• The Audit Committee requested PwC Switzerland’s resignation; PwC Switzerland had been Amcor’s auditor since 2019.
• PwC Switzerland’s audit reports for fiscal years ended June 30, 2026 and 2025 contained no adverse opinions and were not qualified or modified.
• There were no disagreements or reportable events with PwC Switzerland for fiscal years 2026 and 2025 under SEC rules.
• PwC Switzerland will still support residual statutory filings related to the fiscal year ended June 30, 2026.
• Amcor says it did not consult PwC US on accounting or auditing matters during fiscal years 2026 or 2025; no written or oral advice from PwC US was a significant factor in accounting decisions.
• A letter from PwC Switzerland confirming its position was filed as Exhibit 16.1 to the 8-K (dated August 11, 2026).

Why It Matters

• Auditor changes can affect audit continuity and disclosure practices; here the change was driven by Amcor’s status as a U.S. domestic reporting company and growing U.S. operations.
• For investors, the filing indicates no immediate audit concerns: prior audits were clean and there were no disagreements or reportable events reported. The change is procedural and effective after the Company’s annual 10-K filing on August 14, 2026, with PwC US taking over for the transition fiscal year ending December 31, 2026.
