Oliver Graham, CEO of Ardagh Metal Packaging (AMP), said:

“We delivered a strong performance in the third quarter, with Adjusted EBITDA growth of 6% versus the prior year quarter. Our result was towards the upper end of our guidance range with both segments performing broadly in line with expectations. Adjusted EBITDA growth in the quarter was supported by shipments growth in Europe and North America, lower operational and overhead costs, as well as favorable category mix.

Overall global volumes are up over 3% year-to-date versus the prior period and the beverage can continues to benefit from innovation and share gains in our customers’ packaging mix. Our resilient business performance in the current macro environment gives us confidence to further upgrade our full year Adjusted EBITDA guidance to $720-735 million.”

●

Global beverage can shipments declined by 1% in the quarter as growth of 2% in Europe was offset by a decline of 3% in the Americas. North America shipments grew by 1% – broadly in line with the industry following a strong first half (year-to-date volumes +5%) despite temporary operational challenges. Brazil volumes declined by 17%, as industry volumes declined sharply, reflecting a weak consumer backdrop.

●	Adjusted EBITDA of $208 million for the quarter was at the upper end of our guidance range and represented a 6% increase versus the prior year quarter (+3% at constant currency).

●	In the Americas Adjusted EBITDA for the quarter increased by 8% on both a reported and constant currency basis to $126 million driven by lower operational and overhead costs, and favorable category mix, partly offset by lower volumes.

●	In Europe Adjusted EBITDA for the quarter increased by 4% (-4% at constant currency) to $82 million, due to volume/mix and currency effects, partly offset by lower input cost recovery.

●	Adjusted Free Cash Flow expectations for 2025 remain unchanged - expected to be at least $150 million. Expectations for total capex in 2025 of approximately $200 million, of which approximately one-third relates to growth investment.

●	Strong total liquidity position of $627 million at September 30, 2025. Net debt to Adjusted EBITDA ratio reduces to 5.2x, down from 5.6x at September 30, 2024.

●	Regular quarterly ordinary dividend of 10c announced. No change to capital allocation priorities.

●	Publication of sustainability report highlights strong progress towards targets in 2024, including a 10% annual reduction in scope 1 & 2 emissions and a 14% reduction in scope 3 emissions – with scope 3 emissions now 25% below the 2020 baseline.

●	Raising 2025 Adjusted EBITDA guidance to $720-$735 million – based on an expected average euro/dollar currency rate of 1.12 versus an average of 1.086 for 2024. Full year shipments growth forecast expected to be around 3%.
