Expand Capacity: Bainbridge Greenfield Facility Update - Possible Schedule Change

Commentary

• Location of Greenfield site selected in Georgia due to better utilities rates and incentives
• Broke ground in November 2021 and civil engineering work is ongoing
• Some equipment has been pre-ordered to avoid higher prices, but inflation remains a concern, as does lead time for some items ordered and yet to be ordered
• We remain confident that there is ample customer demand for this capacity but we do not want to get caught in supply chain and inflationary unknowns given the cash flow implications
• We are looking at possible schedule changes that might mitigate potential cost over-runs and unplanned delays
• Recent construction cost estimate moved project spend midpoint from $490m to $556m and top end of range moved from $590mm to $612mm
