Stephanie Disher
Chief Executive Officer at Cummins
Thank you, Todd; and good morning. I'm excited to be here for our Company's first earnings call and to provide you with an update of our second quarter 2023 results.
At the end of May, we completed our initial public offering, a significant milestone for our Company and the culmination of multiple years of work. The launch of Atmus provides us with a unique opportunity to grow, both in our core markets and through expansion into industrial filtration market. Our successful IPO would not have been possible without the tireless dedication of our global employees. Every person on our team, from our quality inspector at our dedicated media production facility in Korea to our safety leader in Cookeville, Tennessee, is key to our success. Our people provide premium Fleetguard products and deep industry knowledge to support the success of our customers.
We have made significant progress in our first quarter as a public company and are on track with plans to separate fully from Cummins. I do want to bring to your attention that we filed an 8-K on Tuesday, restating our first quarter 2023 financial statements and revising annual prior periods for 2020 through 2022. Jack will provide more detailed information later in our call, and of course, we want to address any questions you have. We are committed to ensuring a strong internal control environment and to communicating transparently.
I would like to now turn to a summary of our strong second quarter results. I'll start with a high-level overview of our markets and the drivers of our results and then turn to our financial performance. Demand remains strong in our first-fit markets through the second quarter and we expect this to continue through the second-half with our customers reporting strong orders through the end of the year. In the aftermarket, we experienced some destocking by customers through the second quarter, and we expect a softer second-half connected with lower economic activity.
China market continues to be challenging to predict. And whilst we see some recovery from 2022 demand levels, it is a slow recovery; and we expect a continued muted recovery through the end of 2023.
Sales in the second quarter 2023 were $414 million, an increase of approximately 5% from the second quarter of 2022. Increased pricing more than offset lower volume and FX headwinds. Adjusted EBITDA margin rose 220 basis points from the prior year to 19.3%. The benefit of pricing actions coupled with the moderation of commodity and freight costs drove the improvement in profitability.
We are adjusting EBITDA for one-time separation costs, which were $9 million in the second quarter of 2023 compared to $1 million a year ago. Adjusted earnings per share was $0.63 and adjusted free cash flow was $35 million, an increase of $11 million over the same period last year. We have adjusted free cash flow for $2 million of one-time capital expenditures related to separation. Overall, it was a strong quarter and we are continuing to build momentum. We have strong leadership in place and we are working together to create Atmus.
I would like to make some brief comments on our strategic progress in the quarter. You may recall, our strategy is focused on four pillars: Grow share in first-fit in our core markets, accelerate profitable growth in the aftermarket, transform our supply chain, and expand into industrial filtration market. I would like to highlight three areas of strategic momentum during the second quarter.
Firstly, we are a technology leader. Our proven leadership enables us to win first-fit business by solving our customers' complex problems. During the second quarter, we launched our Wuhan, China technical center, this was the first of three transitions as we progressed our technical strategy and establish full separation from Cummins. During the opening of our Wuhan facility, we introduced our next generation of media technology, NanoNet Plus for China, which further extends the performance capabilities of our existing NanoNet technology. The next-generation NanoNet Plus, along with our new technical center, enables us to continue to develop differentiated products in fuel filtration. This further underpins our global market-leading position in fuel filtration.
Secondly, we are focused on transforming our supply chain. One element of this transformation is improving the availability of products for our customers, which will drive share in the aftermarket and profitable growth. During the second quarter, we progressed the implementation of our global distribution strategy through the establishment of new Atmus warehouses in Sao Paulo, Brazil, and San Luis Potosi in Mexico. Our teams have done an outstanding job establishing these new facilities, embedding capabilities and ensuring improved delivery for our customers. The progress in the quarter to deliver enhanced availability for our customers, whilst maintaining disciplined inventory management was remarkable.
And finally, I wanted to focus on our growth potential through expansion into industrial filtration market. At Atmus, we intend to pursue this growth opportunity through a disciplined programmatic approach to acquisitions. We have established a strategy and corporate development team, we have developed a robust pipeline of targets and are continuing to assess acquisition opportunities aligned with our strategy. My leadership team and I are focused on growing beyond our core and we'll continue to update you on our progress.
It has been a big quarter, a successful IPO and launch of Atmus, progress on multiple fronts against our strategic priorities, and strong financial performance. I want to thank all of the Atmus team for their significant contributions.
Now, I will turn the call over to Jack.
