Steph Disher
Chief Executive Officer at Cummins
Thank you, Todd, and good morning, everyone. Our team delivered another strong quarter of performance even as we see softness in many of our global end markets. On the call today, I will provide an update on our performance in the quarter, an update to our outlook for the year, and provide some insights on our growth strategy. Jack will then provide additional details regarding our financial performance.
During the second quarter, we reached a significant milestone of one year as a publicly listed company. Whilst this is an important milestone, more important is our sustained strong performance over the last 12 months. I want to take an opportunity to thank all our global employees for their hard work and dedication to deliver consistently. This has positioned us to recently announce our first quarterly dividend and a share repurchase program. Capital return to shareholders is an important part of our ongoing commitment to strengthen total shareholder value.
Now, let's turn to second quarter financial results and our updated outlook for 2024. We delivered strong financial performance in the second quarter. Sales were $433 million compared to $414 million during the same period last year, an increase of approximately 5%. Adjusted EBITDA in the second quarter was $93 million, or 21.4% compared to $80 million, or 19.3% in the prior period. Adjusted EBITDA for the quarter excludes $4 million of onetime stand-alone costs and $9 million for the same period last year. Adjusted earnings per share was $0.71 in the second quarter of 2024 and adjusted free cash flow was $34 million. Adjusted free cash flow excludes $23 million of onetime separation-related items.
Now, let me provide some insight into our global markets. Beginning first with the aftermarket. Softer freight activity continued during the second quarter and we have yet to see a positive inflection. However, our strong performance is offsetting some of the market weakness and contributing to volume growth. Demand in the U.S. first-fit markets is beginning to slow as expected. In India, markets remain strong while China remains sluggish.
Looking ahead to our outlook, I will start with aftermarket for both on-highway and off-highway, which represents approximately 80% of our global revenues. It is challenging to predict the timing of an aftermarket recovery. We establish our outlook for the aftermarket by considering a number of factors, including third-party metrics and input from our global customers across the value chain. Compared to the prior year, we are expecting our overall global aftermarket revenue to be in a range of flat to up 5%. At a high level, this guidance reflects a declining market with strong market share performance and positive tailwinds from destocking, which occurred in 2023 and is not repeated in 2024.
Let me provide some further detail regarding the assumptions underpinning this guidance. We expect our global markets for aftermarket to be down in a range of 2% to 4%. We are still experiencing year-over-year declines in freight activity and have not yet seen a positive turning point. Overall freight activity is expected to be weaker through the balance of the year than previously expected. In global off-highway, we are seeing softness across the world in construction, mining and agriculture markets.
Offsetting market softness, we expect our outperformance to continue as we accelerate our growth strategy and continue to win new business. We expect our market outperformance to contribute 2% to aftermarket revenue growth. Adding an additional 2% of revenue growth will be the benefits related to destocking year-over-year. You may recall our customers were destocking from 2Q through 4Q in 2023 as supply chains normalized. Pricing is also expected to provide an additional 1.5% year-over-year increase.
Let's now turn to our first-fit market. In the U.S., our view of the heavy-duty market is unchanged. While we are seeing modest improvement in the medium-duty markets, we anticipate declines in the second half of 2024 in line with industry expectations. We are maintaining our outlook for U.S. heavy-duty truck to be down 7% to 12% for the full year. In medium duty trucks, we are raising our guidance to flat to up 5%. Demand for trucks in India is expected to remain strong in both the on-highway and off-highway markets, while in contrast market conditions in China continue to remain at weak levels.
We expect new business wins, including the fuel filtration business of a global OEM, we announced last quarter to partially offset some of the market weakness expected in our first-fit business. Taken altogether, we are raising our revenue guidance to now be in a range of flat to up 3% compared to the prior year, with global sales in an expected range of $1.625 billion to $1.675 billion. We expect continued strong operational performance and the benefits of our first-half performance to carry through the year.
We are raising our adjusted EBITDA margin 25 basis points and expect to deliver adjusted EBITDA margin of 18.5% to 19.5%. We are also raising our adjusted EPS outlook and now expect to be in a range of $2.15 to $2.40.
Now I would like to turn to the capital return to shareholders we announced in July. We are pleased to announce this comprehensive capital return program as part of our ongoing commitment to strengthen total shareholder value. The strong cash generation ability of our business allows us to deliver high-quality solutions to our customers, invest in strategic growth initiatives and now return capital to shareholders. We declared our first quarterly dividend of $0.05 a share and announced the authorization of a $150 million share repurchase program. Our priority for capital deployment remains focused on the execution of the four pillars of our growth strategy, for which I will now provide you with an update.
Our first pillar is to grow share in first-fit. We continue to win with the winners and have secured new vehicle platforms associated with the 2027 U.S. EPA emissions standards. We are leaders in fuel filtration and crankcase ventilation. These continued wins further demonstrate our ability to support customers and provide our industry-leading fleet guard products to solve our customers' filtration challenges.
Our second pillar is focused on accelerating profitable growth in the aftermarket. We are growing our share of the aftermarket by providing our customers with our technology-leading fleetguard products where and when they need them. Our teams continue to aggressively pursue new business around the globe, allowing us to expand our share of aftermarket business. We have recently launched our filtration science campaign to raise our brand awareness and demonstrate how fleetguard products provide industry-leading protection and uptime.
Our third pillar is focused on transforming our supply chain. We continue to improve on-shelf availability as we stand up our own fully dedicated distribution facilities. Over 80% of our volume is being distributed through dedicated Atmus warehouse facilities and we are on track to have substantially all of our volumes on the Atmus network by the end of the year. We continue to drive out costs through investments in automation and efficiencies in our purchasing organization.
Our adjusted EBITDA performance demonstrates the results of our continuous focus on cost reduction. At the midpoint of our guidance, we expect to expand adjusted EBITDA margin 340 basis points since the end of 2022 and our supply chain transformation has been a key component of this expansion.
Our fourth pillar is to expand into industrial filtration markets. We are primarily focused on growing inorganically and we continue to build our M&A pipeline and review opportunities. While we are excited about the possibilities industrial filtration will bring to us, we are taking a disciplined approach in evaluating potential targets. Our focus remains on creating long-term shareholder value and we will move forward with acquisitions when we are confident we can deliver on this value. We will continue to keep you informed of our progress.
Now Jack will discuss our financial results in more detail.
