John Gibson
President and Chief Executive Officer at Paychex
Thank you, Shelby. Thank you, everyone, for joining us for our discussion of the Paychex's first quarter fiscal year '24 earnings release. Joining me today is Efrain Rivera, our Chief Financial Officer and Bob Schrader, Vice President, Finance and Investor Relations.
This morning, before the market opened, we released our financial results for the first quarter. You can access our earnings release on our Investor Relations website, our Form 10-Q will be filed with the SEC within the next day. The teleconference is being broadcast online and will be archived and available on our website for approximately 90 days.
I will start the call with an update on the business highlights for the first quarter. I'll then turn it over to Efrain and Bob for a financial update, and then we'll open it up for your questions.
But before getting into the discussion of our earnings results, I want to take a brief moment here to make a few brief comments to acknowledge Efrain Rivera, who announced his intention to retire as CFO effective October 12th of 2023, though he will remain as a Senior Advisor at least through the end of the calendar year. Efrain has been a valuable member of this senior leadership team at Paychex for the past 12 years. He has provided strong financial stewardship, but more importantly, great strategic leadership as well.
During his time with Paychex, the company has transformed into a technology-enabled services company and we significantly expanded our HR solutions and capabilities. Efrain has been a key strategic advisor and a catalyst for this transformation. Efrain, I think you know how truly I appreciate your intellect, your wisdom, your integrity, the guidance you've given me personally over my decade here and to the company. And we are all in great gratitude for what you've done for each one of us personally and for the company. Our customers, our employees and our shareholders are better off because you were here. So, thank you.
Joining us today is Bob Schrader who will succeed Efrain as CFO. Bob joined Paychex back in 2014 and is taking on progressive leadership roles over the past nine years, including over the last 1.5 years, since I was named President and subsequent CEO, of being the co-lead of many of our strategic review efforts and strategic initiatives. Bob's promotion is the part of a strategic succession plan to bring in an innovative leader who will continue to guide the company going forward.
I want to congratulate Bob, and Bob, I look forward to continuing to work with you as I have in the last 10 years, as we continue to -- continue our track record of delivering strong financial results and continuing to position Paychex as a leader, an innovator and a company that you can count on for predictable and sustainable results.
Now, moving on to the first quarter results, speaking of predictability and sustainability. We have begun the fiscal year '24 with solid growth of 7% in total revenue and 11% in adjusted diluted earnings per share. We've seen operating margin expansion approximately 60 basis points year-over-year, while still investing in our business to drive future growth.
Our first quarter reflected solid execution by our sales, service and all of our teams across Paychex. The demand for our HR technology and advisory solutions continued, resulting in strong quarter of new sales; revenue growth; we saw positive trends in client, revenue and HR outsourcing worksite employee retention during the quarter; and we continue to focus our resources on acquiring and retaining high-value clients.
We are starting to see improvements in some of our key PEO and Insurance metrics during the quarter, with good results across sales activity, insurance attachment and retention. We will know more after our open enrollment season is completed which primarily runs from October through January. But at this time, we believe that the actions we have taken in response to the headwinds we faced in 2023 are beginning to gain traction.
Employment levels within our client base have remained stable. Small businesses, which are central to the U.S. economy continue to show the resiliency. Our Small Business Employment Watch has shown that small businesses continue to add workers at sustained but modest rates. Also, the trend in wages is showing some cooling and wage growth consistent with overall inflation.
Our data indicate a continued stable macro-environment for small and mid-sized businesses. We continue to monitor our leading indicators and are prepared to take appropriate actions to navigate any changes. But again, at this time, we don't see any material change to the macro-environment.
Small businesses have faced challenges getting access to capital and managing cash flows in this environment. This has continued to drive demand for our full-service employee retention tax credit service. I know there's been some recent news of the IRS pause in ERTC processing in order for them to perform increased audits. This is not expected to have an impact on our ability to provide this service, though it may take longer for our clients to receive their funds.
We continue to communicate this opportunity to existing clients and prospects and we continue to file amended returns with the IRS on their behalf. We anticipate that ERTC revenue will be a slight tailwind for the first half of the fiscal year and then turn to a headwind in the back half as the program ends. We are seeing greater adoption of HR software as businesses look to digitize their HR efforts to support the complexities of managing today's workforce in a more efficient manner.
We also continue to see strong demand for our HR advisory solutions as businesses deal with the continued challenges of being an employer in today's challenging employment world. Paychex is uniquely positioned to offer a continuum of HR products, technology and services from do-it-yourself payroll all the way to full-service PEO HR outsourcing. All of these products deliver a strong return on investment for our clients.
For the 13th year in a row, we were named the leading retirement record-keeper by number of plans by PlanSponsor Magazine. Our leadership position in retirement makes us an excellent resource for small businesses and we continue to educate and execute on this opportunity.
There has certainly been a lot of excitement about AI and related technology and advancement around the monetization of large datasets. At Paychex, as we've talked on prior calls, this isn't anything new or it's not a fad. We have been using artificial intelligence to transform our business for over a decade. We have over 200 AI models that are actively working on our business today designed to provide valuable insight, fueled by our vast data assets.
Our award-winning Retention Insights tool uses AI-based predictive analytics to provide HR leaders with early insights into potential employee retention issues. Our Flex Intelligence Engine is an embedded AI chat capability within our Flex platform that allows the customer to get quick answers to over 900 of the most common questions and access over 1,200 instructional resources.
Companies like Paychex with large amounts of data will clearly be the winner with AI and we will continue to harness the power of AI and leverage our extensive data to drive internal efficiencies and provide actionable insights and solutions to our clients.
This quarter, we continued to be recognized for our innovation, service and the positive impact we are having on our customers, our industry, and the world. For the third time Paychex has been recognized by TrustRadius with a 2023 Tech Cares Award for the company's Corporate Social Responsibility programs and our community impact. We also received an award from Selling Power for our commitment to fostering a diverse and inclusive workforce and from Forbes as one of the Best Employers for Women in 2023.
On the product and service side, NelsonHall once again identified Paychex as the leader in its 2023 Next Generation HCM Technology Market Report. We also earned at silver Brandon Hall Group 2023 HR Excellence Award for breadth and depth of training that we provide our HR advisors to keep them up to speed on the ever-changing complexities of the employer-employee relationship.
Paychex was also named the 2023 Constellation Research on their ShortList for best payroll for North American Small and Mid-sized Businesses. The depth and breadth of our product suite provides American businesses the freedom to succeed with the technology and advice that they desperately need to remain competitive in a very complicated world.
I want to thank our over 16,000 global employees who consistently deliver for our clients and our shareholders. It's because of them that we're off to such a good start this fiscal year.
I'll now turn it over to Bob Schrader to give you a brief update on our financial results for the first quarter. Bob?
