Item 2.05 Costs Associated with Exit or Disposal Activities.

On August 7, 2023, the Board of Directors of the Company approved a new 3-year cost take-out to grow restructuring program (the "CTO2Grow Program") as part of Reinvent SEE 2.0. The CTO2Grow Program aims to drive annualized savings in the range of $140 to $160 million by the end of 2025. The total cash cost of this program is estimated to be in the range of $140 to $160 million.

SEE's vision to become a world-class company, partnering with our customers on automation, digital and sustainable packaging solutions, will now be accelerated by Reinvent SEE 2.0 CTO2Grow Program by:

Shifting our go-to-market approach from product to solutions-focused, driving commercial excellence and enhancing customer experience to deliver a durable profitable growth engine;

Optimizing our portfolio across automated protective solutions, fluids & liquids and consumer ready while reducing speed to market on innovations; and

Streamlining our supply chain footprint and SG&A cost to drive further operating leverage and improve business agility and overall profitability.

The Company expects to incur charges in connection with the CTO2Grow Program. Currently, the Company is evaluating the details regarding the timing and amount of charges and the cash outlay by category that may be incurred in connection with these events. The Company will file an amendment to this Current Report on Form 8-k within four business days after it makes a determination of an estimate of the total amount and range of amounts expected to be incurred in connection with the CTO2Grow Program.

The charges associated with the CTO2Grow Program will be excluded from non-U.S. GAAP financial metrics.

Statements in this item 2.05 relating to matters that are not historical facts are forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 reflecting the Company’s current view with respect to future events or objectives and financial or operational performance or results.
