John Gibson
President and Chief Executive Officer at Paychex
Thanks, Bob. I will start today's call with an update on the business highlights for the second quarter and then I'll turn it back to Bob for a financial update, and then of course, we'll open it up for your questions.
We delivered solid results in the second quarter and the first half of the fiscal year. Excluding the impact of the expiration of the ERTC program, revenue growth was 7% in the second quarter as we continue to deliver a comprehensive suite of HCM solutions that help businesses solve real problems. Diluted earnings per share growth was 6% as we continually find ways to operate the company more efficiently, while also enhancing the value proposition that we offer our customers.
The demand for our HR technology and advisory solutions remains healthy as we head into the key selling season. A challenging labor market and rising healthcare and benefits costs are forcing many small businesses to re-evaluate their HR strategies and technology needs and they can rely on Paychex to help them succeed.
Our sales activities and pipelines are strong, most notably in our PO and middle-market HCM businesses, where we have invested, as you know, to take advantage of the growth opportunities we see in these attractive markets and where we believe our breadth of solutions provide us with a competitive advantage. We are fully staffed across our sales and service teams for this critical time of year. We are also investing in advertising to drive improved awareness and adoption of our expanded product offerings.
Our PO business continues to perform exceptionally well, driven by our robust value proposition as evidenced by solid worksite employee growth due to strong sales performance, record levels of retention and higher overall insurance enrollment. While the underlying business is strong and our attachment and participation levels in our health plans across the country increased mid-single digits, enrollment in our Florida at risk medical plan was flat year-over-year. We also saw more employees opting for lower cost health plans in light of rising healthcare costs. These factors create a headwind to our pass through revenue, but have no impact to our earnings or the strength of our PO value proposition.
Our revenue retention improved during the past year and remains above pre-pandemic levels as we continue to remain disciplined on acquiring and retaining high-value clients. Client retention has improved since last year and retention in our HR outsourcing solutions remain near record levels. Client losses are down over the past year with improvements across all our employee size segments. Our continued strong retention in a highly competitive marketplace speaks to the hard work and execution of our service teams and the strength of our value proposition.
The pace of US job growth has moderated over the past year and overall customer employment levels have remained consistent with our expectations. Small and mid-sized businesses remain resilient and are generally optimistic as we head into a new year with hiring intentions in November rebounding to the highest-level since last November. We continue to make investment in our product suite to help our customers solve their biggest problems.
In October, we announced the Paychex Recruiting Copilot, a digitally AI-powered solution designed to help clients proactively find talent in a challenging labor market. Although it's still early, we are seeing momentum building for the product as we head into the busiest time of year for hiring. According to a recent NFID survey, 55% of small businesses reported hiring or trying to hire in November and 48% reported few or no qualified applicants for the positions that they're trying to fill. This is something we're actively trying to address.
We recently expanded our HR analytics offering to provide our customers with deeper and more meaningful insights. With the addition of the Premium Plus offering that we announced last month, businesses of all sizes now have access to real current market data for compensation benchmarks to enable them to more effectively recruit, manage talent and develop growth strategies. Premium Plus also has a generative AI assistant and a chat interface. We're pleased to report strong early adoption of our HR analytics solution, which we are planning to launch broadly to our PO clients this month.
Through AI Insights, we are using generative AI to provide our customers with access to robust data and meaningful insights through simple, easy-to-use interactions. Since launching the product in September, we've seen a significant increase in customer engagement. Over 80% of the early adopters have actively engaged with the platform and we've seen AI focus usage increase significantly in the past three months.
As a reminder, Paychex has used AI technology for many years and we believe Gen AI offers a new set of opportunities for value creation, especially when paired with a large and high quality dataset. Paychex captures $14 billion data elements last year and we pay one in 12 private sector workers in the US, giving us one of the largest workforce datasets in the industry. Our vast and growing dataset provides us with the ability to deliver actionable insights to customers and strengthens our competitive moat.
Our clients can now leverage Paychex Flex Perks to complete -- compete for scarce talent more effectively. Perks is an award winning digital marketplace that offers our clients' employees access to affordable benefits and discounted products and services from third party providers. Perks is available at no cost to employers and payments are processed automatically through payroll deductions. Since we launched the product, in September, over 100,000 client employees have purchased at least one product offered in the marketplace.
The value proposition of our new product innovation is resonating with our customers and also with industry experts. The Paychex Flex Perks was awarded the Top HR Product of the Year award by HR Executive and also recently received a Brandon Hall Excellence in HR Technology Silver Award. Paychex was also recently named a leader in payroll services by NelsonHall for the eighth consecutive year. We were evaluated and placed in the leader quadrant for our ability to deliver immediate client benefit and meet future client requirements.
To sum it up, we remain focused on our North Star, and that's simply is helping small and mid-sized businesses succeed by offering the most comprehensive suite of HCM solutions, best-in-class advisory support and actionable insights greened from our large proprietary data based upon our long history of helping businesses.
I will now turn it over to Bob to give us a brief update on our financial results for the second-quarter. Bob?
