BOSTON, MA (November 17, 2020) - Today, Vistaprint, the marketing and design partner to millions of
small businesses, and the 17-time NBA World Champion Boston Celtics announced a multi-year partnership in which
Vistaprint becomes the Exclusive Marketing and Design Partner of the Boston Celtics. As part of the partnership, the
Vistaprint logo will appear in Celtics signature team colors on the front left shoulder of the Celtics’ game jerseys
beginning with the 2020-21 season.

The partnership between the Celtics and Vistaprint is designed to make a lasting impact on local small businesses
throughout the Greater Boston area and across New England. Throughout the partnership, Vistaprint will work closely
the Boston Celtics and the Boston Celtics Shamrock Foundation to support the efforts of the Boston Celtics United
Social Justice initiative, including building economic opportunity and empowerment in minority communities.

“As a company with deep roots in the Boston area, we are thrilled to announce this partnership with our hometown
the Boston Celtics,” said Vistaprint Chief Marketing Officer Ricky Engelberg. “Even more so, we’re proud to join up
the Celtics to shine a spotlight on the important role small businesses play here in our community and across the
country. Though our partnership with the Celtics is just beginning, Vistaprint’s partnership with small businesses
been in place for more than 20 years. We are excited to use this new platform to help enhance that 20-year
commitment in
a way that we’ve never done before. This work has never been more important as small business owners face economic
hardship brought on by the pandemic.”

The collaboration will provide resources for local small businesses, including financial assistance, educational
resources, and marketing and design services. The Celtics and Vistaprint will commence by working together to
Boston-area small businesses with integrations into highly visible team platforms, including digital and social
content, fan engagement and promotions. The partnership also includes significant assets across the Maine Red Claws
CLTX Gaming, including primary jersey patch placement for both teams, which marks the first time that has been
across NBA, G League, and NBA 2K League franchises.

“We share much in common with Vistaprint, but where we feel most connected is our shared values of commitment to
excellence, innovation, and community,” said Rich Gotham, Boston Celtics Team President. “This partnership will
allow us
to work together to bring out the best in both organizations.”

The collaboration is the latest effort by Vistaprint in a series of initiatives to support businesses during the
pandemic and beyond. Earlier this year, Vistaprint partnered with the Celtics on the “Food for Heroes” program,
purchasing food from hard-hit local restaurants and donating it to front line workers. In addition to Vistaprint’s
with the Celtics, the company launched the Save Small Business Fund, a $1 million grant program in partnership with
US Chamber of Commerce Foundation to help alleviate the financial losses small business owners faced as a result of
Covid-19. Vistaprint has also become a leading provider of face masks, face shields and custom printed materials to
small businesses get back to work safely. To date, it has raised $5 million in cash and in-kind product donations to
support small businesses through its mask sales.

Excel Sports Management’s Properties team was engaged by the Boston Celtics to help secure the partnership.
