Patrick Goris
Chief Financial Officer at Carrier Global
Thank you, Dave, and good morning, everyone. Please turn to slide 10. Q4 earnings were ahead of our expectations and the guide we provided in October, even though reported sales of $5.1 billion were about $150 million lower. Organic sales were flat, and a favorable one-point tailwind from currency translation was offset by the impact of divestitures.
Organic sales were lower than we expected, mostly in our North America residential HVAC business, as lower volumes reflected demand, and distributors drove down field inventories. Q4 adjusted operating profit was up 8% compared to last year, despite flat sales driven by favorable price cost and productivity, partially offset by investments. As a result, adjusted operating margin expanded by 80 basis points compared to last year.
Adjusted EPS of $0.53 was up 33% year-over-year and was ahead of our implied Q4 guide of $0.50. Compared to our expectations, HVAC margins were a little better. Fire and Security and refrigeration margins were a little light, and we benefited from discrete tax items and somewhat lower net interest expense.
Free cash flow of $829 million was about $150 million better than our October guide, and we generated $2.1 billion of free cash flow for the full year, which is 92% of adjusted net income. Excluding some of the M&A related fees and cash restructuring spend which are adjusted out of our results, we converted over 100% of adjusted net income into free cash flow in 2023.
Moving on to the segments starting on slide 11, the HVAC segment had another good quarter with significant operating margin expansion despite flat sales. Organic sales were down 1%, mostly due to North America residential HVAC sales being down high-teens. This headwind was almost completely offset by continued exceptional growth in light commercial HVAC, high single digit growth in commercial HVAC, including over 20% growth in the Americas, and another quarter of double-digit growth in aftermarket.
North America residential HVAC volume was down in the high 20s, which was partially offset by continued price realization and the positive mix up related to the 2023 SEER transition. Our light commercial HVAC business finished a very strong year with another quarter of about 20% year-over-year growth. This business was up 35% for the full year, an industry best.
Adjusted operating margin was up 250 basis points year-over-year on flattest sales growth driven by price, cost and productivity. This led to a full year operating margin for this segment of 16.6%. Overall, another great year for our HVAC business.
Transitioning to refrigeration on slide 12, as expected, organic sales for the segment returned to growth in the quarter and were up 6%. Within transport, refrigeration container was up significantly around 60%. Our global truck and trailer business was up low single digits, with North America and Europe flat and strong growth in Asia. Our Sensitech business, which provides comprehensive visibility solutions for tracking and monitoring temperature sensitive products, was up high single digits. Commercial refrigeration was down high single digits year over year. Operating margin contracted 160 basis points year-over-year due to investments and a few one-time items such as warranty and insurance.
Moving on to Fire and Security on slide 13, organic sales were down given a very tough compare in Access solutions partially offset by strength in industrial fire which was up almost 20%.
Adjusted operating profit was down 7% versus the prior year, driven by volume mix and currency partially offset by favorable price cost. The revaluation of the Argentinian peso impacted margins by over 100 basis points. Full year operating margin for this segment was about 15%.
Turning to slide 14. As you can see on the left side of the chart, backlog for our longer cycle commercial HVAC business continues to increase while backlogs in our shorter cycle businesses continue to normalize. Total company orders were down low single digits in the quarter, mostly as a result of our North America truck and trailer orders being down significantly compared to last year.
In Q4 of 2022, North America truck and trailer orders were up an exceptional 120% year-over-year as we opened the 2023 order book. Excluding North America truck and trailer, Carrier's organic orders were up mid-single digits in Q4.
HVAC orders returned to low single digit growth as residential HVAC orders were up mid-teens, which more than offset the decline in light commercial orders, which were down roughly 40% as lead times continued to improve in that business. Commercial HVAC orders were up low single digits, and the longer cycle backlog remained strong up around 30% on a two-year stack and extending well into the second half of 2024.
Refrigeration orders were down about 20% in the quarter, with global truck and trailer orders down roughly 50%, reflecting the very tough comp in North America, I mentioned earlier. This was only partially offset by a return to growth in orders in a container business where orders were up nearly 60%, and low single digit growth in commercial refrigeration. Overall, we entered 2024 with robust longer cycle backlogs in commercial HVAC and a return to orders growth in key businesses such as residential HVAC and container.
Moving on to slide 15 guidance. Let me start with some key assumptions embedded in guidance related to our portfolio transformation. We haven't included a full year of Viessmann Climate Solutions as we closed the acquisition on January 2. You may recall that we previously communicated that our business exits will remain in continuing operations until they close. Therefore, with definitive agreements in place for the sale of both global access solutions and commercial refrigeration, our guidance assumes a mid-year exit date, and so both businesses are included in 2024 guidance through the end of June.
Accordingly, our guidance assumes the net proceeds from these two exits will be used to pay down debt. We include industrial fire and residential and commercial fire for the full year 2024 into our guidance, and we will do so until there are definitive agreements in place and we have a good estimate as to the likely exit date.
Now to details of the 2024 guidance. We expect reported sales of about $26.5 billion, including mid single digit organic sales growth with about equal contribution from price and volume mix. We expect mid single digit organic growth for Viessmann Climate Solutions to contribute about 20% to reported sales growth and a deconsolidation of KFI along with the divestitures of global access solutions and commercial refrigeration to represent about a 5% headwind to reported sales.
Adjusted operating margin is expected to be between 15% and 15.5%, up over 50 basis points compared to '23, driven by price, volume and productivity. Productivity includes an $80 million benefit from restructuring actions we executed earlier this quarter, as we simplify our structure, given our transformation. The impact of Viessmann Climate Solutions on overall company operating margin is about neutral.
Core earnings conversion, that is, excluding the impact of acquisitions, divestitures and FX is over 30%. Incorporating an estimated 23% adjusted effective tax rate, this gets us to an adjusted EPS guidance range of $2.80 to $2.90, which includes about a $0.07 headwind from the Viessmann acquisition as we expected.
Underlying free cash flow is expected to be up about 10% compared to 2023. Reported free cash flow will be lower given some of the portfolio transformation activities. Similar to 2022 when we exited Chubb, cash flow from operations will be impacted by tax payments related to the gains on the sales of these business exits. Given the large expected gains on the two transactions already announced, we expect free cash flow to net about $700 million. This includes about $1.7 billion of cash outflows related to the expected tax payments on the gains of access solutions and commercial refrigeration, transaction fees related to all four exits and the Viessmann transaction, and additional restructuring. Similar to 2023, we expect higher than typical restructuring charges in 2024, about $100 million pretax.
Seasonally, we expect our free cash flow to be back half weighted. Unlike the tax payments on the gain of the business exits, proceeds from the divestitures will show on the cash flow statement as investing activities, and therefore do not impact free cash flow. As shown on the right side of the slide, we expect mid single digit organic growth in all three segments. Fire and Security operating margin of about 14% reflects the absence of the higher margin global access solutions business in the second half of the year.
Now moving to slide 16, 2024 adjusted EPS Bridge. This chart shows how adjusted EPS increases from $2.73 to $2.85 at the midpoint. Our guidance includes the benefit of volume leverage and strong productivity leading to over 30% core earnings conversion and over 50 bps of margin expansion. Think of the dark blue as our core business representing all the businesses we will retain, and the lighter blue representing the four businesses we are exiting.
We expect the earnings of our core business to be up close to 15% in 2024, despite the dilutive impact of Viessmann. You can see the net contribution from Viessmann Climate Solutions and the net impact of losing six months of earnings from access solutions and commercial refrigeration offset by interest savings from the proceeds. We expect the headwind from tax as we return to a 23% adjusted effective tax rate.
On the far right, you see that our full year 2024 guide includes about $0.30 of adjusted EPS related to businesses being exited. The $0.30 of course, does not reflect the benefit of the redeployment of expected net proceeds from the exits of industrial fire and residential and commercial fire. As usual, we provide estimates of other items in the appendix on slide 20.
With respect to capital deployment in 2024, we recently announced a dividend increase payable starting with the February dividend, and our focus this year will be on deleveraging through free cash flow generation and net proceeds from the exits. As we return to about two times net leverage, we do intend to resume share repurchases.
Finally, before I turn it over to Dave, let me provide some additional color on the first quarter. We expect low single digit organic revenue growth with about 50 bps of margin expansion. We have a $0.10 year-over-year adjusted EPS headwind, including $0.06 from Viessmann, $0.02 from last year's gain on the sale and refrigeration, and $0.01 each from the KFI deconsolidation and a higher tax rate.
We therefore expect Q1 revenues of a little less than $6.5 billion and adjusted EPS to be right at about, but not above $0.50. We do expect organic revenue growth sequentially improved throughout the year, with easier comparisons in the second half of 2024. We expect a little less than 50% of full year adjusted EPS to be realized in the first half of the year and the balance in the second half.
With that, I'll turn it back over to Dave.
