Amcor plc 8-K

What Happened
Amcor plc announced on May 1, 2026 (filed via Form 8-K) that its Board changed the company's fiscal year end from June 30 to December 31. The change creates an abbreviated transition fiscal period running July 1, 2026 to December 31, 2026. The company said its first full calendar fiscal year under the new schedule will be the year ended December 31, 2027.

Key Details

• The Board action was taken May 1, 2026 and was reported in the Form 8-K filed May 6, 2026 (Item 5.03).
• Transition Period: July 1, 2026 – December 31, 2026 (abbreviated fiscal year).
• First full calendar fiscal year under new schedule: year ended December 31, 2027.
• The company will file a transition report on Form 10-K/T for the Transition Period and will continue reporting quarterly results under its current fiscal year until December 31, 2026.
• Fiscal quarters will remain aligned with calendar quarters.

Why It Matters
This is an administrative change to Amcor’s reporting calendar that affects fiscal reporting periods and the timing of annual filings. Investors should note the abbreviated six-month transition period in 2026 and expect a Form 10-K/T covering that period. Historical period comparisons, year-over-year metrics and timing of filings may shift as the company moves from a June 30 fiscal year end to a December 31 year end.
