Thanks, Brad. We want to stress that we managed our business based on, first, hitting our long-term objective of becoming a top 10 broker in 10 years. Next, we focused on performance over the full year rather than on a quarter-to-quarter basis, particularly given that the timing of completed partnerships can shift. As such, we believe our year-to-date and pro forma results can provide important insight into how we are performing.
During the quarter, we completed 3 partnerships for total cash consideration of $23.7 million. The success of the IPO has already been positive in generating additional interest from potential partners. For the 9-month period ended September 30, 2019, revenue rose 72% to $101.3 million compared to $59 million in the prior year period, attributable to our 2019 partnerships, organic growth and a full 9 months of contribution from our 2018 partnerships. For the same 9 months ended September 30, 2019, adjusted EBITDA rose 68% or $9.2 million over the prior year period to $22.6 million. For the same period, unaudited pro forma revenue, which assumes our 2019 partnerships have been acquired on January 1, 2018, was $116 million.
Turning to our balance sheet. As of September 30, 2019, we had cash and cash equivalents of $11.1 million and long-term and related party debt of $193.4 million. Subsequent to the end of the quarter, we successfully completed our IPO offering, generating approximately $242 million of net proceeds, a portion of the proceeds was used to repay the subordinated debt of $88.4 million, and we concurrently closed the agreement. Additionally, last week, we repaid a $65 million portion of our revolving line of credit agreement and now have borrowing capacity of $85 million under that agreement.
With that, I thank you for your time, and we'll now open up the call for Q&A. Operator?
