Vicente Reynal
Chairman and CEO at Ingersoll Rand
Thanks, Vik. Moving to slide 11. Our Industrial Technologies and Service segment delivered solid year-over-year revenue growth of 6% on top of approximately 20% growth in Q2 of last year. Adjusted EBITDA margins were 29.7%, up 230 basis points from the prior year, which was driven primarily by gross margin expansion.
Book-to-bill was onetime, with organic orders down 2.6%, which was largely in line with expectations. Important to note that we saw sequential order growth of 5% which were primarily driven by compressors.Moving to the program highlights. Compressor orders were up low single digits while still comping a low double-digit growth in Q2 of 2023. It's good to note that we saw positive order growth across Americas, EMEIA and Asia Pacific, excluding China. Compressor revenue was up mid-single digits in the quarter, which we view still healthy after mid-teens growth in Q2 of 2023. Industrial banking orders were up low single digits and revenue was up mid-teens.
For innovation in action, we're highlighting Elmo Rietschle new high-speed blower technology, which was recently launched in Europe. This patented oil-free technology offers a 60% reduction in energy consumption compared to a traditional blower technology, enabling productivity for the customer and reducing total cost of ownership by up to 50%.
Turning to slide 12. The PST segment achieved 6% organic order growth and deliver adjusted EBITDA of approximately $103 million with a margin of 30.3%. It is encouraging to see that the legacy Ingersoll Rand Life Science business saw organic order growth of 8%. In addition, short cycle orders in the PST segment remained positive with book and ship orders up mid-single digits year-over-year. We see organic order growth stabilizing, and we remain positive about the underlying health of the PST business and it remains on track to meet our long-term Investor Day growth commitments.
For our PST innovation in action, we're highlighting an extremely innovative technology within the legacy Ingersoll Rand Life Science business. Combining multiple technologies across different brands, we have developed a product offering in micro-fluidics to create a customized liquid handling automated system for biotech R&D labs as well as the production of personalized therapeutics.
This innovative technology drives up to 50% productivity versus existing processes in a market that is expected to grow approximately 20% through 2027. On the next slide, I would like to spend a minute discussing the current market trends as we always get a lot of questions about our leading indicators. A key leading indicator of our short-to-medium cycle business is marketing qualified leads or MQLs. As illustrated on the top chart, our MQL continues to grow.
In Q2, we saw organic MQLs up 13% year-over-year. As for the longer-cycle component of our portfolio, one key indicator we look at is the funnel activity for engineered-to-order compressor systems. We remain encouraged as the funnel activities up 27% in the first half year-over-year. While the leading indicators have been encouraging, we have seen an elongation in the decision-making process with the prolonging of the time to convert an MQL to another.The feedback we hear contains multiple reasons. But some of the most often cited are customer site readiness and too many projects happening at the same time which is impacting EPC engineering capacity. Having said this, this situation is encouraging as we look to 2025. Switching back to 2024 expectations, from a regional perspective, Americas is on pace to deliver mid-single-digit organic revenue growth. EMEIA remains stable, and we see very good pockets of growth, primarily in the emerging markets of India and the Middle East.
Asia Pacific and specifically China is a key driver of the reduction in our organic growth guidance. Moving next to inorganic growth. We're anticipating approximately $270 million of incremental revenue from our recently acquired M&A. ILC Dover is the largest driver, contributing approximately $220 million of revenue in 2024. The biopharma business as highlighted earlier in the deck remain strong and on track to deliver double-digit growth. However, we do anticipate that the Aerospace & Defense revenue to be down approximately $30 million versus our initial expectations and this is driven by lower-than-expected activity levels in our space business, predominantly related to the next-generation spacesuit, which is often referred to as xEVAS.
As we move to slide 14, given the solid performance in the first half, our recently acquired M&A and our expectation of continued operational execution fueled by IRX, we are once again raising our 2024 guidance. The company revenue is expected to grow overall between 6% to 8%, which is up 200 basis points versus our initial guidance. As discussed on the previous slide, we anticipate positive organic growth in the range of 0% to 2%. The reduction in the range versus our prior guidance is largely attributable to lower organic growth expectations, specifically in China.
FX is now expected to be a 1% headwind for the full year, which is down approximately 100 basis points as compared to our previous guidance. M&A is projected to contribute approximately $440 million, which reflects all completed and closed M&A transactions as of July 31, 2024. Corporate costs are planned at $170 million and will be incurred relatively evenly per quarter for the balance of the year. Total adjusted EBITDA for the company is expected to be in the range of $2.01 billion and $2.06 billion, which is up approximately 14% year-over-year at the midpoint.
Adjusted EPS is projected to be within the range of $3.27 and $3.37, which is up 2% versus prior guidance and approximately 12% year-over-year at the midpoint. On the bottom right-hand side of the page, we have included a 2024 full year guidance bridge, showing the changes in our latest guidance as compared to our previous guidance provided in May. As you can see, the primary driver of adjusted EPS growth is associated with operational execution partially offset by increases in the net impact from interest and FX. We're also seeing a $0.02 improvement in our adjusted EPS as compared to our previous guidance from an improvement in our full year adjusted tax rate.
Gross interest expense is now expected to be approximately $250 million and net interest expense will be approximately $170 million and will be incurred relatively evenly per quarter for the balance of the year. The adjusted tax rate is expected to finish in the year between 22% and 23%. No changes have been made to our guidance on capex spend as a percentage of revenue, free cash flow to adjusted net income curvation or share count, all remain in line with our previous guidance.
Finally, as we turn to slide 15, I'm very pleased with how our teams continue to execute despite overall market conditions. We continue to deliver record results and our updated guidance is reflective of our first half performance and ongoing momentum. With our most recent guidance, we continue to expect to deliver results above of our long-term Investor Day targets. Based on the midpoint of our 2024 full year guidance, the 4-year CAGR for organic revenue growth will be approximately 10%. We think this continues to show durable outperformance over the cycle. That in combination with our inorganic growth, robust margin expansion and execution of IRX, we expect to deliver a 4-year CAGR in excess of 25% for adjusted EPS.
To our employees, I want to thank you for the strong results thus far showing the impact each of you have as owners of the company. Thank you for your resiliency, hard work and focused attention. We believe the power of IRX, combined with our ownership mindset and leading portfolios, strengthens the durability of our company while delivering long-term value to shareholders.
With that, I will turn the call back to the operator to open the call for Q&A.
