Thomas Okray
Executive Vice President & Chief Financial Officer at Eaton
Thanks, Craig. On Page 9, I'll begin with highlighting a few key points regarding our Q4 results.
Revenue was up 12% with organic growth of 15%, partially offset by a 4% foreign exchange headwind and a 1% favorable net impact from acquisitions. This outcome illustrates our focus of prioritizing growth in our customers. With total revenue growth of 12%, we posted solid operating leverage. Operating profit grew 21% and adjusted EPS grew 20%. Further, excluding the $0.05 impact from foreign exchange, growth in adjusted EPS would have been 23%. All in, strong organic growth and margins enabled us to report all-time record adjusted earnings of $825 million and adjusted EPS of $2.06 which was above our guidance midpoint.
Lastly, I'd like to note that we continue to raise the bar with our Q4 records for both segment operating margin and segment operating profit.
Moving on to the next chart, we summarized strong financial performance for our Electrical Americas business. For yet another quarter, we have set all-time records for sales, operating profit and margin. Further, we've also set all-time records for these metrics for the full year. Organic sales growth accelerated from 18% in Q3 to 20% in Q4 with robust growth in every end market and particular strength in utility, data center and commercial and institutional markets. Operating margin of 23.7% was up 450 basis points versus prior year, benefiting from higher volumes. In addition, incremental margins were quite strong at 47%. We continue to manage price effectively to more than offset inflationary pressures. Further, it should be noted that Electrical Americas outperformed their original 2020 guidance by 100 basis points.
Orders in backlog continued to be very strong. On a rolling 12-month basis, orders were up 34% which remains at a high level with strong growth across the board and particular strength in data center, utility and industrial markets. Backlog ended the year up 87% versus prior year and increased sequentially from Q3. In addition to the robust trends and orders in backlog, our major project negotiations pipeline in Q4 was up nearly 100% versus prior year from especially strong growth in manufacturing, data center, industrial and utility end markets. Overall, Electrical Americas had a strong quarter to round out a very good year and continues to be well positioned as we start 2023.
Moving to Page 11, we show results for our Electrical Global segment which produced another strong quarter, including records for Q4 and full year records for sales, operating profit and margins. Organic growth was up 8% which was entirely offset by headwinds from foreign exchange of 7% and divestiture of 1%.
With respect to organic growth, we saw strength in utility, industrial and data center end markets. On a regional basis, we posted high single-digit organic growth in IEMEA and mid-single-digit organic growth in APAC. Operating margin of 18.7% was down 80 basis points versus prior year primarily due to foreign exchange headwinds. We continue to see good order intake. Orders were up 11% on a rolling 12-month basis with strength in data center and commercial and institutional markets. Backlog growth of 17% also remains strong.
Before moving to our industrial businesses, I'd like to briefly recap the combined Electrical segments. For Q4, we posted organic growth of 15%, incremental margins of 44% and operating margin of 21.8% which was 250 basis points of year-over-year margin improvement. For the full year, our Electrical segments grew 15% organically, generated 33% incremental margin, increased margin 140 basis points, posted 25% rolling 12 months order growth and increased backlog 68%. We are confident that we're well positioned for continued growth with strong margins in our overall Electrical business.
The next chart recaps our Aerospace segment. We posted all-time record sales and operating profit for both the quarter and on a full year basis. Organic growth accelerated to 11% with a 4% headwind from foreign exchange. This growth was driven by strength in commercial markets with commercial aftermarket up 35% and commercial OEM up more than 20%.
Relative to profit, operating margin was strong at 24.5%. And it's worth noting that Aerospace outperformed their original 2020 guidance by 100 basis points. Order growth and backlog are very encouraging. On a rolling 12-month basis, order acceleration continued, up 24% compared to 22% in Q3 and 19% in Q2 with strength across all end markets. Similar to Q3, we saw especially strong growth in military OEM orders, up 80% in the quarter which positions us well for growth in 2023 and confirms our expectations for increased defense spending, including breakout performance in 2024. Year-over-year backlog increased from 17% in Q3 to up 21% in Q4.
Moving on to our Vehicle segment on Page 13. Vehicle had strong revenue growth in the second half of the year. In Q4, revenue was up 16% with 18% organic growth and 2% unfavorable foreign exchange. This coming off 19% organic growth in Q3. We saw growth across all markets with particular strength in North America and South America light vehicle. We also saw double-digit growth in APAC. Operations came in at 15.2% with unfavorability to prior year, primarily due to manufacturing inefficiencies. As expected, we were able to completely offset the impact of inflation with pricing in Q4. We also secured wins in new and sustainable technologies, such as EV gearing and transmissions, with a large and growing opportunity pipeline.
On Page 14, we show results for our eMobility business. We generated very strong growth in the quarter. Revenue was up 58%, including 17% from organic growth and 44% from the acquisition of Royal Power, partially offset by 3% negative foreign exchange. Margin improved 780 basis points versus prior year driven by higher volumes and the impact from Royal Power. We remain encouraged by the growth prospects of the eMobility segment. Since 2018, we've won $1.4 billion of mature year revenues in this business, including a recent $400 million win for power protection and distribution units with a European customer. This is a major new program win in both U.S. and European markets with production starting in 2024. This win demonstrates Eaton's ability to leverage our capabilities across our entire portfolio, including core technology in both electrical and industrial businesses.
We partnered with our customer to electrify their mobile platform with solutions, including Breaktor and Bussmann fuses. We also leverage our extensive vehicle expertise and added content from our Royal Power acquisition. Overall, we continue to make progress toward our long-term goal to create a $2 billion to $4 billion business with 15% margins by 2030. We are now on track to exceed our expectation to deliver $1.2 billion of revenue and 11% margin by 2025.
Moving to Page 15. I'm going to unpack a theme that Craig mentioned at the top of the call related to our strategic investments in working capital to support strong orders and backlog which enables accelerated organic growth. Overall, in spite of supporting surging orders and backlog, we are driving working capital improvements.
To illustrate the trend, I'll provide a couple of examples. Net working capital to orders and inventory as a percentage of backlog. Focusing on the left side of the chart, the average value of our Electrical and Aerospace quarterly orders in 2022 was more than 20% higher than 2021 and 33% more than 2019. However, to support these increasing orders, we have only slightly increased the absolute value of our working capital. The result is shown in the graph on the left side of the page. Our ratio of net working capital at year-end to trailing 12-month orders has stepped down significantly from 2019 to 2022.
Moving to the right side of the chart. Another way to look at working capital efficiency is comparing backlog growth to inventory growth. At the end of 2022, our Electrical and Aerospace backlog reached approximately $11 billion which is up almost 160% since the end of 2019. However, to support this much larger backlog, inventory for our Electrical and Aerospace businesses has only increased by 38% since 2019. The graph on the right side of the slide highlights the significant improvement since 2019. Our inventory as a percentage of backlog has been roughly cut in half from the end of 2019 to the end of 2022. We are supporting a much larger backlog with a smaller percentage of inventory.
In summary, we have prudently prioritized taking care of our customers and capturing growth which has required investments in working capital and has impacted free cash flow metrics in the short term. That said, we are managing working capital more efficiently.
The 2023 guidance on Page 16 shows that we are well positioned for another strong year of financial performance. Our organic growth guidance for 2023 is a range of 7% to 9% with particular strength in Electrical Americas and Aerospace with organic growth rates of 8% to 10%. eMobility is also a standout with 35% organic growth guidance at the midpoint tied to the ramp of new programs. These organic growth rates correspond to our end-market growth assumptions that we provided on our Q3 earnings call and that Craig will update in a few slides.
The end-market growth, combined with increased backlog, provides tremendous visibility and confidence in our 2023 outlook. For segment margins, our guidance range of 20.7% and 21.1% is a 70 basis points improvement at the midpoint from our 2022 all-time record margin of 20.2%. In addition to projecting strong organic growth for 2023, we're also growing margins and continue to invest in future organic growth.
Moving to Page 17. We have the balance of our guidance for 2023 and Q1. I'll touch on some highlights. For 2023, we are guiding adjusted EPS in the range of $8.04 to $8.44 which has a midpoint of $8.24 is 9% growth over 2022. We expect continued foreign exchange headwinds which we estimate between $100 million and $200 million adverse. For operating cash flow, our guidance of $3.2 billion to $3.6 billion is a 34% increase at the midpoint over 2022. The key drivers here are a combination of higher earnings and improved working capital, particularly lower inventory levels as supply chains normalize.
While our plan includes significant improvement in free cash flow during 2023, I'll note that we anticipate due to higher interest expense and capex in Q1 as well as timing-related headwinds such as taxes that free cash flow in Q1 will be relatively flat year-over-year. For share repurchases, we anticipate a range of $300 million to $600 million.
Moving to Q1. For Q1, we are guiding organic growth of 8% to 10%, segment margins between 19.5% and 19.9% and adjusted EPS in a range of $1.72 to $1.82.
Now, I'll hand it back to Craig to walk us through the market outlook and wrap up the presentation.
