Olivier Leonetti
Executive Vice President and Chief Financial Officer at Johnson Controls International
Thanks, George, and good morning, everyone.
Let me start with the summary on Slide 5. As George discussed at the beginning of the call, our team did an incredible job responding to the cyber incident. The disruptions we experienced during the quarter were factored into the guidance we provided last month. Total revenue of $6.1 billion was flat year-over-year, while organic sales were down 1% as continued declines in global residential HVAC and accelerated weakness in China's install business more than offset mid-single-digit growth in service and continued growth in Applied HVAC.
Segment margins declined 90 basis points to 12.8% impacted by tough comps in our shorter cycle Global Products business, coupled with ongoing weakness in China's macroenvironment. Adjusted EPS of $0.51 exceeded our guidance of $0.48 to $0.50 as we return to more normalized seasonality. The quarter was impacted by lost momentum from the cyber incident, accelerated weakness in China and tough comps in our Global Products business. Below the line, we saw headwinds from net financing charges due to higher interest rates and increased debt levels in line with historical trends.
On the balance sheet, we ended the first quarter with approximately $1.8 billion in available cash and net debt increased to 2.2 times, which is within our long-term target range of 2 to 2.5 times. The elevated cash position was a direct result of proactive action to mitigate the potential impacts of the cyber incident on cash flow. Adjusted free cash flow improved $180 million year-over-year and we anticipate further improvement as we progress through the fiscal year.
Let's now discuss our segment results in more detail in Slide 6 through 8. Beginning on Slide 6, organic sales in our Global Products business declined 1% year-over-year with volume declines offsetting price. Global Products saw continued strength in Commercial HVAC, which grew low-single-digits after growing low-double-digits in the comparable period one year ago. We have been investing in our Applied HVAC business for the last couple of years, deploying resources to align to more attractive opportunities resulting in further share gains in calendar 2023.
Fire & Security declined low-single-digits. We believe that the majority of the tough year-over-year comparisons in the shorter cycle indirect business are bottomed out and we should see a return to growth in calendar 2024. Industrial Refrigeration had another strong quarter, growing over 35%, driven by EMEA/LA. Global residential declined high-single-digits, driven by a greater than 20% decline in North America, which more than offset low-single-digit growth in rest of world. North America continues to face market softness. And we believe we have one more quarter with these challenges before the industry begins to see growth in the second half of the year. We're improving our North America market share and see momentum building.
Despite ongoing weaknesses in the European heat pump market, rest of world benefited from strong growth in Japan. Our book-to-bill business continues to normalize with improved lead times and our Global Products third-party backlog decreased 10% from the prior year to $2.3 billion. Adjusted segment EBITA margins declined 240 basis points to 17.9% as we benefited from insurance proceeds from a warehouse fire in the comparable period last year. We're beginning to see better cost absorption in our factory and expect Global Products margins to improve throughout the rest of the fiscal year.
Moving to Slide 7 to discuss Building Solutions performance. Orders increased 1% as mid-single-digit order growth in North America and EMEA/LA was more than offset by a greater than 30% decline in APAC, which was primarily the result of further deterioration of the China install business. As the China real estate market continues to weaken and the outlook remains mixed, we have begun to optimize our go-to-market strategy and have become more selective in the business we pursue. Organic sales were flat in the quarter against a tougher comparison of low-double-digit growth in the prior year quarter. Install declined mid-single-digits and more than offset mid-single-digit growth in service. Segment margins declined 10 basis points as accelerated weakness in China offset positive mix in the quarter. Building Solutions backlog remains at record levels, growing 7% to $12.1 billion. Service backlog is flat and install backlog grew 8% year-over-Year.
Let's discuss the Building Solutions performance by region on Slide 8. Orders in North America increased 6% as we continue to see strong demand across our HVAC & Controls platform growing high-single-digits following high-teen growth in the comparative period a year ago. Overall, there was broad-based demand in our healthcare, data center, government and education sectors. Install orders increased 9% year-over-year with solid growth in both new construction and retrofit.
Sales in North America were up 4% organically with strong growth across our HVAC & Controls platform, up low-teens year-over-year. Our install business grew 4% with continued momentum in new construction, up over 25% year-over-year. Organic sales in service grew 4% in the quarter, benefiting from high-single-digit growth in our recurring revenue contracts. Segment margins expanded 20 basis points year-over-year to 11.5%, driven by the continued execution of higher margin backlog and strength in our higher margin service business. Total backlog ended the quarter at $8.4 billion, up 11% year-over-year.
In EMEA/LA, our orders were up 5% with continued strength in service, up 12%. Demand in institutional gained momentum in the quarter, growing 50% year-over-year, driven by public projects in Europe. Industrial Refrigeration had another strong quarter with greater than 45% growth. Sales in EMEA/LA grew 2% organically led by high-single-digit growth in service with high-single-digit growth from our recurring contracts and strong double-digit growth in our shorter cycle transactional business. Applied Commercial HVAC and Fire & Security grew low-single-digits within the quarter. Segment EBITA margins of 7.7% remained flat as the growth in service was offset by the conversion of lower margin install backlog. We anticipate strong margin expansion in EMEA/LA through the remainder of the fiscal year. Backlog was up 10% year-over-year to $2.4 billion.
In Asia Pacific, as I mentioned earlier, orders declined 31% due to further deterioration of the China install business and we are being more strategic in the deals we select. Overall, APAC-severed orders grew low-single-digits driven by high-single-digit growth in our shorter term transactional business. Service in the Asia Pacific declined 21% as the installation business was impacted primarily by accelerated weakness in China. Our service business grew 5% in the quarter. The weakness in China's install business was broad-based across the overall portfolio with HVAC & Controls, down high-teens and Fire & Security down 20%. Segment EBITA margins declined 140 basis points to 9.1% as weakness in China offset positive mix in our service business. Backlog of $1.3 billion declined 21% year-over-year.
I would now like to turn the call over to Marc to discuss our second quarter and fiscal year 2024 guidance. Marc?
