An Important Message from Curt Begle, President, Berry Health, Hygiene & Specialties

Dear HHS team,

Today I am pleased to provide a high-level overview of NewCo’s go-forward organizational structure along with the currently identified leadership positions to be effective on the day of closing, with a focus on the roles related to the core business and organizational integration. Additional announcements will be made in the future.

Over the last few months, I’ve met with the Board of Directors of Glatfelter and Berry, as well as senior leaders from both organizations to align and create the best operating model for NewCo to launch on day one ready to meet and exceed our business objectives and stakeholder expectations.

NewCo’s Operating Model

NewCo will be structured using a regional operating model, with two primary regions:

The business structure will be very similar to how we operate today. For most HH&S team members, it will not impact current day to day responsibilities. Employees with global responsibilities will continue to operate within their normal duties unless we determine those roles would better serve in support of a region. In some cases, we may expand the scope of certain job responsibilities to best position the team to deliver on the business needs.

NewCo Leadership Team

While the organizational structure sets a solid foundation for NewCo, success requires a collective effort of all valued team members. I am excited to communicate a second round of appointments to leadership positions, representing both the current Glatfelter and HH&S teams. Additional announcements will be made in the future.

An Important Message from Curt Begle, President, Berry Health, Hygiene & Specialties

David Parks will assume the role of President – Americas. This position will include responsibility for the combined Glatfelter and HH&S businesses in the America’s.

Achim Schalk will assume the role of President - EMEIA & Asia. This position will include responsibility for the combined Glatfelter and HH&S businesses in Europe and Asia.

Robert Weilminster will lead Corporate Development, Strategy, Investor Relations and Integration. He will begin transitioning his current responsibilities to David Parks this summer as he prepares for his new role.

Paul Harmon will lead Global Innovation, Sustainability, Corporate Branding and Marketing.

Eileen Beck is currently the Senior VP, Global Human Resources & Administration at Glatfelter and will assume the Global role to lead Human Resources.

Kathy Vanderheyden is currently VP of Operations for Glatfelter’s Airlaid and Hygiene business, along with global safety and quality, and will assume the Global role to lead BEX & Integration, Quality, Regulatory and EHS.

Michele Forsell will be responsible for our Global Finance Business Partners and will transition her General Manager duties of Building & Construction to David Parks prior to closing.

Tracey York will continue to play a key role in Human Resources, including Human Resources leader for the Americas.

Phil Lerro is currently Glatfelter’s Chief Information Officer and will assume the role for NewCo.

An Important Message from Curt Begle, President, Berry Health, Hygiene & Specialties

It is important to note this is not the full team that will report into each of these leaders. With this announcement, we will begin the important process of assembling these organizations and will continue to share details as they emerge.

As we transition to our new operating model, I want to personally thank Daniel Guerrero for his 25+ years of exemplary service. In his many roles over the years, Daniel has been a steadfast leader and his contributions have been invaluable. I am forever grateful for the bond we developed during our time together in HH&S. As he has done with so many of our employees during his tenure, Daniel made me a better businessperson and became a close friend. Daniel will transition his current responsibilities to David Parks this summer to ensure a smooth transition for the LATAM team and will contribute to the integration work streams through closing.

As we share additional details regarding the newly named leaders and the organizational structure in the weeks ahead, I ask each of you to continue to perform at your highest level to deliver on our 2024 commitments, which is extremely important as we set our New Company up for success.

Stay tuned for more exciting news over the summer months, which will include the announcement of our much-anticipated new name, logo, and brand!

Curt
