Video Transcript:

Good morning team, I’m Dave Marberger, CFO, filling in for Sean today. Needless to say it was an exciting week last week. We are thrilled about the acquisition of Pinnacle Foods and closing out a strong FY18. The future is bright for Conagra, but of course, there is a lot of work to be done. The Pinnacle deal is a significant, synergistic acquisition, and we will incur a large amount of debt and have a high leverage ratio as we approach closing the deal. Leverage ratio is a term I want all of us to understand and track. It is the relationship of our total debt to our EBITDA, which is your earnings before interest, tax, depreciation and amortization. Post closing, Conagra will have a leverage ratio of 5x, which means we will have over $11 billion of debt. Now, we need to stay focused on delivering our financial commitment, which will include a greater focus on cash flow. You might remember when Sean talked about the meaning of these dollar bills that you see behind me – these are the result of friendly wagers between us as we travel the road meeting with investors. As Sean often says to me, “Cash is King.” As we move forward with the acquisition, I have asked my finance team to work more closely with all of the teams across the company to discuss how we track cash flow, and to get a better understanding of how cash flow is impacted by the work we do, and what we can do to improve it. The decisions you make and the work you do in your day-to-day jobs impacts cash flow; some examples include buying vs. leasing something, reducing cash discounts and extending payment terms with our suppliers, reducing working capital, leveraging Procurement to ensure we competitively bid for goods and services, and many more. I encourage you to act like owners and think about how your team can better focus on cash flow as well. The more cash we generate, the faster our leverage ratio goes down, which means we can pay off this debt sooner and gear up for more growth opportunities. If there’s one thing I’ve come to learn in my last two years here, it’s that when the people of this organization focus, they execute really, really well. Thanks for all you do. Have a great week and for those of you in the U.S., have a safe and relaxing fourth of July.
