Most importantly this transaction gets us bigger, better, and stronger, but maintains our very strong balance sheet position. We will be able to keep our leverage at 3.5x EBITDA and that is a result of this deal being largely a stock for stock transaction with a little bit of cash involved— so kudos to the finance team for that. As we blend these two companies together, the combined company will have a pro forma cash flow of over $820 million for pro forma 2021. And we expect that cash flow to continue to grow steadily from there in the years in the future. And importantly, this transaction is accretive to what Crestwood would have done on its own, meaning that we are going to see an increase in distributable cash flow per unit, and that has allowed us to agree to increasing the distribution by 5%. So, we will be increasing our quarterly distribution by 12.5 cents a year up to $2 and 62.5 cents on an annual basis after we close this transaction.
It also adds another great producer to our tremendous G&P portfolio as we will add Oasis Petroleum, which is one of the largest Bakken producers, and we will be the largest midstream service provider to Oasis. They will own a bunch of our stock, we will have a strong alignment of interests, and I know the two management teams will work very well together as they plan their very active drilling and development program in the Bakken over the next few years. We will be there to build out gathering and compression and processing capacity for them, so excited about that.
This transaction is exciting, and it represents a significant milestone for us, as we note in the letter to you. We have been on this path for years. 2021 is going to wind up being one of the most important years ever, as we close the First Reserve buyout earlier in the year, the strategic sale of Stagecoach to pay down our debt, and now a significant addition to our gathering and processing business in both the Bakken as well as the Delaware.
We are right on track and we are doing a great job. We could not do it without all the great work that you all do in the field and in the office, continue to support in our strategies for growing in our own footprint in the three areas where we operate, which is Bakken, Powder, and Delaware. So exciting time, hope you all are thinking about this and what role you will play in the integration. Everybody will be involved—this is an all company transaction. We think this transaction will make Crestwood bigger, better, and stronger. We are really excited about rolling this out to the market. So, thanks for all that you do, continue to work safely. These are going to be great assets to add to our portfolio. And thanks a lot, we will talk to you soon in the employee town hall.
