Craig Arnold
Chairman and Chief Executive Officer at Eaton
Thanks, Yan.
We'll start on Page 3, where we summarize the key highlights of another strong quarter. We generated adjusted EPS of $2.84 a share, an all-time record and up 15% from prior year. We also delivered record segment margins of 24.3%, up 70 basis points from last year. And we're raising our guidance for segment margins and adjusted EPS for the year. We did experience a couple of extraordinary events in the quarter that impacted our revenue.
First, the widely publicized strike taking place in the aerospace industry and then Hurricane Helene, which impacted several of our Electrical Americas factories at the end-of-the quarter. While both of these events will have an impact on our revenue outlook for Q4, they're not impacting our demand and it's only timing. In fact, our markets continue to be strong. On a rolling 12-month basis, electrical orders were up 12% with Electrical Americas orders up 16% and aerospace orders increased by 6%. This led to another quarter of growing and record backlogs, up 26% for Electrical Americas, up 14% for aerospace with strong book-to-bill ratios. On balance, we're pleased with our results and are well positioned for a record year of performance and expect to carry strong momentum into 2025.
Turning to Page 4. We once again are sharing our overview of megatrends and how they're driving growth in our end markets. I think the key message here is one of breadth, both in the number of megatrends and the number of our end markets that are positively impacted. Something we think is unique to Eaton and will allow us to grow at an accelerated rate for years to come. Last quarter, we provided an end market update on our commercial and institutional segment, highlighting the strong growth outlook for institutional and infrastructure markets. Today, we intend to provide a forecast for residential markets and how energy transition is creating new growth opportunities in residential homes. And as we've done in recent earnings calls, we'll also provide an update on the growing number of mega projects announced during the quarter.
So let's begin with that on Slide 5 in the presentation. This chart shows a summary of mega projects that have been announced since January of 2021 in North America. As a reminder, a mega project is a project with an announced value of $1 billion or more. Through Q3, we're now at 504 projects with a cumulative value of $1.6 trillion. And the backlog now stands at $1.8 trillion, up 30% from last year. And I'd also point out the announcements are continuing to accelerate with Q3 up 48% versus Q2. Approximately 16% of these products have started and we expect a record number of starts in 2025. Many of you have asked the questions about cancellations, which we continue to monitor as well. To date, cancellations have been modest, around 10% and well below historical levels.
For projects that have started, we've won over $1.7 billion of orders and our win rate is almost 40%. Of note, we're in active negotiations on another $3 billion of orders, up 175% from last quarter. While mega projects continue to garner a lot of attention, deservedly so, the Dodge Momentum Index, which tracks commercial and institutional projects that are less than $500 million are also at record levels, up 22% in the quarter. Taken together, we think they provide a strong validation of the megatrends and support our view on the long-term outlook of our end markets.
As we prepare for the growth ahead, we're making investments in our manufacturing capacity naturally. And on Slide 6, we show an update of our incremental capacity investments, which now stand at $1.5 billion, up $500 million from our previous estimate. The increase reflects our increasing confidence in our outlook as well as increasing demand that we're now seeing in data center markets. These multi-year investments with the largest addition coming in the second-half of '25 and '26 and the capacity investments cover several product families and importantly can be used across most of electrical end markets. I'd also add that most of the additional capacity is what we consider a light assembly and modular, which allows us to be both flexible and efficient as we deploy capital. Overall, our expansion projects are on track with a number of sites starting to ramp-up production. For example, we recently opened a 110,000 square meter facility in Juarez, Mexico that produces motor controllers and switchboards. And we also opened a new manufacturing facility in the Dominican Republic that will increase our supply of Bussmann fuses.
Next, on Slide 7, we're highlighting our residential markets, which include naturally the electrical infrastructure for both new construction and renovation. Residential markets represent 6% of Eaton's total sales and 8% of electrical sales. And the key message here is that these secular trends that we've been talking about that are impacting our industrial and commercial markets are also impacting homes. As a result, the electrical content in homes continues to grow. The growth in solar, electric vehicles, energy storage and the electrification of heating and cooking are fundamentally changing in the requirements in home. And new safety codes and standards are also continuing to drive the need for higher electrical content. And as you know, the current IRA tax incentives for electrical panel upgrades are designed to support this growing need for more electrical power.
No doubt, residential markets have been feeling the impact of higher interest rates over the last couple of years. With markets now feeling like they've reached the bottom, the housing shortage remains and we should see positive growth from this point forward. Estimated at a 6% CAGR over the next four years from what's been a drag on growth over the last 24 months should turn positive now. With the -- and within the residential market, Eaton is especially well-positioned. As homes become more electrified, generate and sometimes sell electrical power, become bigger consumers of electricity, they also need to become smarter. We address these changes in our Everything as a Grid, including Homes slide -- which we show on Slide 8.
For more than a century, power has flowed in one direction from central power plants into homes. Today, there is a new reality, thanks to the addition of solar power, electric vehicles, energy storage, all on the top of the need to run a more electrified home. In simple terms, homes can now act as energy hubs, producing their own power, managing their electrical loads and selling power back to their local utility, all of which requires more sophisticated electrical equipment.
Eaton's home as a grid approach creates smart energy systems that allow homeowners to reduce costs, participate in demand response programs, improve resiliency, including islanding from the grid and to optimize the home by selecting which electrical loads they want to run during a power outage. So in addition to homes require more electrical power, homes now require -- are now required to be more intelligent, to be connected and to be integrated into a home as a grid solution.
Today's fully grid-ready homes have up to 5x the electrical content of a traditional home, a trend that will only increase overtime and a tremendous opportunity for Eaton. One example of how we're implementing our Home as a Grid strategy can be seen in the recently announced collaboration with Tesla. As you know, Tesla is one of the biggest names in energy storage, and they needed a solution that would allow homeowners and installers to simplify the integration of energy storage, solar and load management in the home. This is especially important in the existing home market of more than 40 million homes with only 100 amp service. Eaton's first to market and what we call AbleEdge smart breakers provide homeowners with intelligent load management capabilities. This technology allows homeowners to turn their standard loads into a smart load center without replacing the electrical panel. Together with our partners, our systems will manage your solar, your energy storage and your electrical loads. And it's simple to install. It provides better functionality and at a much lower cost than other solutions. In fact, we estimate our solution will be three to five times lower cost. Our AbleEdge smart breakers will be available in early 2025, and we look forward to growing our partnership with Tesla.
Now, I'll turn it over to Olivier to take us through the financial results for the quarter.
