Jim Bidzos
Executive Chairman, President and CEO at VeriSign
Thank you, David. Good afternoon to everyone and thank you for joining us. Before we cover results, I'd like to note that last week we marked 27 years of 100% uninterrupted availability for the.com and.net domain name resolution system. This milestone represents an unparalleled achievement in our industry for operating secure, stable, and resilient DNS infrastructure for well over a quarter of a century amidst some of the most technologically significant changes the world has ever experienced.
Our teams have successfully built, maintained, operated and evolved the infrastructure that enables hundreds of billions of queries a day and supports trillions of dollars in global commerce. In fact, we answer, on average, 328 billion queries per day, billion with a b, 24 hours a day, seven days a week, 365 days a year. And that's over 3.7 million /second. We do this amidst ever increasing internet demand and resilience, evolving technology and a challenging global cyber threat environment.
Turning now to our results, we delivered another quarter of operational and financial stability by focusing on our mission as a critical Internet infrastructure provider. For the second quarter, revenues grew 4.1% year over year, operating income grew 7.1% year over year, and earnings per share grew 12.3% year over year. At the end of June, the domain name base.com and.net totaled 170.6 million domain names. During the second quarter, the domain name base decreased by 1.8 million names.
From a new registration perspective, the second quarter ended with 9.2 million new registrations compared with 10.2 million names for the same quarter last year. The renewal rate for the second quarter of 2024 is expected to be approximately 72.6% compared to 73.4% a year ago. As we have previously reported, we continue to see US registrars prioritize ARPU over customer acquisition through higher retail pricing levels and reduced spend on marketing to new customers compared with prior years.
These factors impacting new registrations are impacting new registrations and renewal rates and are leading to weaker trends in 2024 that are below our original expectations. During the second quarter, the US region was lowered by about 800,000 names. In addition, and as expected, China-related weakness continues and contributed to most of the remaining sequential decline in the second quarter. The domain name base from our EMEA region was up slightly during the second quarter. We have rolled out new registrar marketing programs over the past several weeks to support our registrars and our goal of returning to domain name base growth in the second half of 2025. However, given the ongoing impact of the factors we've mentioned, we now expect the change in the domain name base to be between negative 3% to a negative 2% for full year 2024.
Our financial and liquidity position continues to remain stable with $690 million in cash, cash equivalents and marketable securities at the end of the quarter. During the second quarter we repurchased 2.2 million shares for $388 million. Effective today, the board of directors has increased the amount authorized for share repurchase of VeriSign common stock by $1.11 billion to a total of $1.5 billion authorized and available under the share repurchase program, which has no exploration. Now I'd like to turn the call over to George. I'll return when George has completed his financial report with closing remarks.
