Exhibit 99.9

Customer Letter

Dear [NAME]:

I wanted to personally reach out to you with some important news about our company.

Today we announced that Snyder’s-Lance has reached a definitive agreement to be acquired by Campbell Soup Company. The press release can be found here.

We are excited about joining the Campbell family and the significant opportunities it will present for the combined company’s stakeholders. The transaction will provide consumers of the combined business with an even greater variety of better-for-you snacks. As we move forward, we will continue to build upon our heritage as a premium snack food company with an uncompromising focus on our customers, ingredients, quality and taste.

Campbell is a highly respected leader in our industry, and I want to provide a little more insight into the breadth of their global portfolio and why we are such a great fit. Founded in 1869, Campbell’s iconic brands include Campbell’s, Goldfish, Pepperidge Farm, Prego, V8 and it has more recently added Bolthouse Farms and Pacific Foods. Campbell has been building on its impressive heritage by strengthening its core business and expanding into faster growing spaces, such as snacking, to meet consumer preferences and diversity its portfolio.

Along with our highly complementary businesses, Snyder’s-Lance and Campbell have similar cultures and share an unrelenting commitment to providing consumers with quality and delicious food. Further, Campbell is a purpose-driven organization guided by delivering “Real Food that matters for life’s moments,” which squarely aligns with our passion “to make quality snacks for any occasion.” Our companies also share similar cultures driven by family- and founder-led brands and a strong focus on ingredients, quality and taste. We look forward to capitalizing on the unique strengths of both companies to even better serve you.

Looking ahead, we expect to complete the transaction by early in the second quarter of calendar year 2018. Until then, Snyder’s-Lance and Campbell will continue to operate as independent companies. I want to emphasize our commitment to providing you with the same high-quality products and service that you have come to expect from us. Both Snyder’s-Lance and Campbell share a focus on customer satisfaction and we expect the transition will be seamless for you and all of our customers.

I’ve attached a Q&A, which I hope will address some of your immediate questions. We are committed to keeping you informed throughout this process as we have new information to share. In the interim, please don’t hesitate to reach out to me or your regular contact at Snyder’s-Lance if you have any additional questions or need support.

Thank you for your partnership and continued loyalty to Snyder’s-Lance. We look forward to continuing to provide you with quality snacks for any occasion.

Sincerely,
