Registration Open for Annual 9/11 Memorial Stair Climb at Lambeau Field

APPLETON, WI – Pierce Manufacturing Inc., an Oshkosh Corporation (NYSE:OSK) business, proudly announces registration is now open for the 13th annual 9/11 Memorial Stair Climb at Lambeau Field in Green Bay, WI. Co-sponsored by the Green Bay Metro Fire Department and Pierce Manufacturing, this year's climb will occur on Saturday, Sept. 20, 2025. Open to all who wish to honor the 343 firefighters who lost their lives on Sept. 11, 2001, all funds raised from the event will benefit the National Fallen Firefighters Foundation (NFFF). Participants are encouraged to register early at piercemfg.com/climb.

"The 9/11 Memorial Stair Climb is a powerful reminder of the courage, sacrifice, and unity which defines the fire service," said Chief Matthew Knott of the Green Bay Metro Fire Department. "Each year, we are humbled by the incredible support from our community and are proud to honor the 343 firefighters who gave everything on that tragic day. Together, we climb to ensure their legacy lives on and to support the critical work of the NFFF."

Recognized as one of the largest stair climb events in the nation, the 9/11 Memorial Stair Climb at Lambeau Field continues to grow each year. In 2024, nearly 2,300 participants from across the fire service community, their families, friends, and supporters helped raise funds for the NFFF. This year, the Green Bay Metro Fire Department and Pierce Manufacturing teams hope to grow the event to over 2,500 participants.

During the event, participants climb the equivalent of 110 stories—the height of the World Trade Center towers—on the steps of Lambeau Field. Each climber carries an honor badge displaying the name and photograph of one of the fallen firefighters, symbolically completing the heroic journey. Upon reaching the equivalent of the 78th floor—the highest point firefighters reached on 9/11—climbers will ring a fire bell in solemn tribute.

"It’s both an honor and a privilege for Pierce to be a small part of the fire service, and we’re incredibly proud to continue growing this event in support of the National Fallen Firefighters Foundation and the brave men and women who serve our communities," said Bob Schulz, president of Pierce Manufacturing. "Each year is as meaningful as the next as we pay tribute to the 343 firefighters who selflessly put others ahead of themselves on 9/11. We deeply
appreciate the support of our partners, volunteers, and climbers who make this event possible. Their dedication ensures we never forget the sacrifices made."

Event details are as follows:

• Registration Fees: $35 per climber through July 11, $40 from July 12 to August 22, and $45 from August 23 through event day.
• Event T-Shirts: Guaranteed for participants who register by August 22. All climbers will
