2. Why pricing matters for Smurfit Westrock
Containerboard pricing is a key driver of profitability for integrated paper-and-packaging companies because price realizations typically flow through to revenue and EBITDA with a lag, while much of the cost base is fixed or semi-fixed. The renewed month-to-month increase supports the bull case that 2026 results can improve if pricing holds while volumes stabilize. (packagingdive.com)
