Warren Gardiner
Chief Financial Officer, Intercontinental Exchange at Intercontinental Exchange
Thanks, MC. Good morning, everyone, and thank you for joining us today. I'll begin on slide four with some of the key highlights from our third quarter results. Adjusted earnings per share totaled $1.30, up 34% year-over-year, marking the best third quarter in our company's history. Net revenues totaled a record $1.8 billion and, on a pro forma basis, increased 11% versus last year, with all three of our business segments contributing to the strong year-over-year growth. Total transaction revenues grew 13%, while total recurring revenues, which accounted for nearly half of our business, increased by 10%. Third quarter adjusted operating expenses totaled $755 million, including $35 million related to Bakkt, which, after successfully completing its merger with Victory Park, recently began trading on the NYSE. Adjusting for Bakkt, third quarter operating expenses would have been $720 million, in the middle of our guidance range, while operating -- or while our adjusted operating margin would have been 60%, up over 100 basis points year-over-year. Looking to the fourth quarter, we expect adjusted operating expenses to be between $737 million to $747 million. Relative to the full year outlook provided on our second quarter call, the fourth quarter is now expected to include approximately $10 million related to the Bakkt stub period and $10 million to $15 million of performance-related compensation as we expect to reward our employees for their contribution to the strong results we are once again on track to achieve in 2021.
Record year-to-date free cash flow has totaled nearly $2 billion. These strong cash flows, along with the divestment of our $1.2 billion stake in Coinbase, has enabled us to reduce leverage to under 3.25 times at the end of September, nearly a full year ahead of schedule. As a result, we expect to resume share repurchases, including up to $250 million in this year's fourth quarter. We anticipate updating you on our 2022 capital return plans early next year. In addition, we announced in October that we have agreed to sell our stake in Euroclear for EUR709 million or approximately $820 million. We expect to determine the use of Euroclear proceeds as we approach closing, which we expect will be -- will occur in 2022. Now let's move to slide five, where I'll provide an overview of the performance of our Exchange segment. Third quarter net revenues totaled $959 million, an increase of 16% year-over-year. This strong performance was driven by a 30% increase in our interest rate business and a 38% increase in our energy revenues, including 34% increase in our oil complex, a 73% increase in European natural gas revenues and a 72% increase in revenues related to global environmental products. Importantly, total open interest, which we believe to be the best indicator of long-term growth, is up 18% versus the end of last year, including 11% growth in energy and 28% growth across our financial futures and options complex.
Recurring revenues, which include our exchange data services and NYSE listings, increased 6% year-over-year, including 10% growth in our listings business. This acceleration in growth was driven by an increasing number of operating company IPOs choosing the NYSE, particularly in the technology and consumer sectors. Looking to the fourth quarter, we expect recurring revenues in our Exchange segment to be between $330 million and $335 million. Turning now to slide six, I'll discuss our Fixed Income and Data Services segment. Third quarter revenues totaled $477 million, a 6% increase versus a year ago. Recurring revenue growth, which accounted for nearly 90% of segment revenues, also grew 6% in the quarter. Within recurring revenues, our fixed income, data and analytics business increased by 5% year-over-year, including another double-digit growth in our index franchise, while other data and network services grew 9% driven by continued customer demand for additional network capacity. Looking to the fourth quarter, we expect that our recurring revenues will improve sequentially to a range of $415 million to $420 million and that full year revenue growth will be approximately 6%, at the high end of our guidance range. Let's go next to slide seven, where I will discuss our Mortgage Technology segment.
Please note that my comments on revenue growth are on a pro forma basis. Despite a double-digit decline in industry origination volumes, our Mortgage Technology business grew 7% year-over-year and achieved record revenues of $366 million. While third quarter transaction revenues declined slightly, they were more than offset by a 33% growth in our recurring revenues, which, at $143 million, once again exceeded the high end of our guidance range and accounted for nearly 40% of total segment revenues. Our outperformance relative to industry trends continues to be driven by increased customer adoption of digital tools across the workflow. While these secular growth trends have been a clear tailwind for our recurring revenues, there is also opportunity to drive accelerating adoption across our transaction-based businesses such as our closing solutions, where revenue increased by 30% in the third quarter. Looking to the fourth quarter guidance, we expect that recurring revenues will once again grow sequentially and be in a range of $147 million to $152 million. At the midpoint, this represents growth of approximately 25% year-over-year, which is on top of 20% growth achieved in last year's third quarter. In summary, we once again had strong contributions from each of our businesses and across the asset classes in which we operate. We delivered double-digit growth in revenue, operating income and earnings per share. We also generated strong cash flows, reduced leverage to under 3.25 times, announced the divestment of our stake in Euroclear and successfully took back public on the NYSE. As we look to the end of the year into 2022, we remain focused on meeting the needs of our customers, continuing to drive growth and create value for our shareholders.
I'll now turn the call over to Ben.
