David G. Barnes
Chief Financial Officer at Trimble
Thank you, Rob. Slides 6, 7 and 8 cover the financial highlights for the quarter and the year. Organic revenue growth in the fourth quarter was plus 3% and for the year was plus 1%. Excluding the Agriculture, business growth was 6% in the fourth quarter and 4% for the year. Standout metrics for 2023 include a 470 basis point improvement in gross margin and $555 million in free cash flow, enabled by profit growth and the success of our efforts to bring inventory levels down.
With net debt at $2.8 billion, we remain ahead of the deleverage plan we put in place at the time of the Transporeon acquisition. We have paid down $268 million of the debt incurred to finance the deal. We ended the year with net leverage of 2.8 times, only modestly above our long range target of 2.5 times. The JV with AGCO is pending regulatory approval, and we continue to expect that the transaction will close in the first half of this year. For modeling purposes, we have assumed that the deal closes early in the second quarter. With debt paydown following the AGCO JV transaction close, our leverage will be below 2 times.
Slide 9 covers revenue trends by geography and business model. $1.98 billion of ARR is the standout highlight, up 24% year-on-year and up 13% on an organic basis. Product revenues, which are nonrecurring and predominantly our bundled hardware and perpetual software were down 3% year-on-year. Excluding Agriculture, product revenues were down less than 1%, reflecting the stabilization of these businesses now that dealer inventories have come well down from their peak in early 2022. Dealer inventories are now broadly in line with dealer's business outlook, and our sales trends going forward are expected to track underlying demand trends. By geography, growth in North America reflects the relative strength that Rob referenced earlier. APAC revenues were strong, driven by growth in Australia and India. Revenues were down organically in Europe, reflecting challenging macroeconomic conditions across many the end markets we serve there.
Slide 10 breaks down performance at the segment level:
In Buildings and Infrastructure, the highlight in the quarter was the strong performance of our recurring revenue offerings. Bookings in our AECO software businesses increased over 30% year-on-year, driven in part by the strong cross-sell and TC1 performance, which Rob mentioned earlier. Aided by the bookings performance, segment ARR grew year-on-year by just under 20%, with net -- net retention over 110%, and at the highest levels this business has seen. Segment revenues of non-recurring offerings, principally machine control for civil construction customers, were relatively flat year-on-year, resulting in total segment revenue up organically by 10%. Segment margins were up by 290 basis points year-on-year, driven both by fixed cost leverage and by the mix shift toward higher margin software offerings.
In Geospatial, revenues grew organically by 1%. A revenue in this segment breaks down across three broad categories: field sales to end users; government business; and OEM business. Sales of our core survey and mapping products to end users returned to meaningful growth in the quarter, reflecting a healthier state of dealer inventories and improving underlying market conditions. Offsetting the strong end user growth, component sales to OEMs were down as we lapped some unusually large shipments a year ago. Segment margins were up by 180 basis points, driven principally by lower component input costs versus year ago levels.
In Resources and Utilities, organic revenue for the quarter was down year-on-year by 4%. Excluding sales of products to Agriculture customers, Resources and Utilities revenues were up by approximately 10%. Segment operating margins were lower year-on-year by 160 basis points, driven principally by lower revenue.
In Transportation, revenue was up 1% organically. Segment organic ARR was up mid-single digit as growth in our transportation enterprise software and maps businesses offset the anticipated impact of churn in our North American mobility offerings. Transporeon remains an inorganic comparison, and the highlight in the quarter for Transporeon was achieving a record level of bookings up over 20% versus prior year. We were encouraged by the sales performance of the team in light of the difficult macro dynamics in Transporeon's core European market. Segment margins increased year-on-year by 610 basis points, reflecting the higher margins of Transporeon and margin progression in the balance of the segment.
Let's move now to 2024 guidance on Slide 11. I will focus on our performance, excluding our Agriculture business and including on a go-forward basis, our more limited exposure to Ag, as a 15% owner of the JV and a supplier of products to the JV. For the sake of completeness, we show on Page 11, two views, a reported view with the Ag business included through the first quarter of 2024; and an as-adjusted view without the Agriculture business, which will ultimately be operated within the JV.
The outlook for ARR growth remains strong, driven by momentum across our AECO software businesses. We expect full-year organic growth rates in the 11% to 13% range, off our year-end 2023 levels of $1.98 billion. As-adjusted organic revenues are expected to grow for the year in the 4% to 7% range. Please note that our fiscal 2024 will include 53 weeks, and the extra week will increase full-year and fourth quarter revenues by approximately $85 million. On an as-adjusted basis, we expect margins to improve with EBITDA margins between 26.5% and 27.5%. This represents margin improvement year-on-year of between 100 and 200 basis points. The margin improvement will come from a combination of improved software mix and the impact of the cost actions we took coming out of 2023.
From a cash flow perspective, we expect full-year cash flow of approximately 0.85 times non-GAAP net income, excluding the costs relating to our AGCO JV transaction, and the impact of the 53rd week, free cash flow is estimated to be approximately equal to non-GAAP net income. Our base cash flow forecast assumes no change in tax legislation. A bill moving through the U.S. Congress will, if enacted, restore the immediate expensing of R&D for tax purposes. If passed, this legislation would improve incrementally our cash outlook for 2024 by approximately $130 million. Our EPS forecast for the year reflects the beneficial impact of our planned deleveraging following the close of the AGCO JV and up to $800 million of share repurchase. We expect EPS for the year in the range of $2.60 to $2.80.
I'll finish by offering a few comments on how our guidance for 2024 breaks out by quarter and by segment. We expect organic revenue growth to be strongest in Buildings and Infrastructure. Software businesses and Buildings and Infrastructure are expected to grow in the mid-to-high teens with product-related businesses up slightly, leading to organic revenue growth for the full-year of between 11% and 13%. Buildings and Infrastructure organic growth includes approximately $70 million from the 53rd week. We plan to accelerate model conversions from perpetual to subscription software, tied with hardware in our civil construction business.
Geospatial revenue is expected to be down slightly on an organic basis, with growth in field sales in survey offset by lower sales to U.S. federal customers where business tends to be lumpy from year-to-year. We will also accelerate model conversions from perpetual to subscription software in our survey and mapping business.
Resources and utilities, as-adjusted organic growth will be up in the high-single digits, led primarily by continued growth in our positioning services business.
Transportation revenues are expected to be up in the mid-single digits for the year and relatively flat on an organic basis with growth in Transporeon offset by lower North American mobility revenue. We expect reduced hardware revenue and mobility, as we are intentionally pivoting that business away from lower margin hardware sales to OEMs, instead focusing on the higher value-added data flows. From an operating margin perspective, we expect to grow margins year-over-year in the Buildings and Infrastructure and Resources and Utilities segments. Transportation margins will be up slightly, while Geospatial segment margins are expected to be down year-over-year due to changes in customer and product mix.
For the first quarter, let's turn to slide twelve for additional color. On an as-adjusted basis, we expect organic growth between 2% and 6% and EBITDA margin between 26 and 27%. Buildings and Infrastructure is expected to drive most of the organic growth in the first quarter, with low-single digit growth in Geospatial. As-adjusted Resources and Utilities is expected to post high-single digit revenue growth in the first quarter. During the first quarter, we expect to see softness in Ag. Weakness in the global Ag market is certainly a factor, but the bigger driver is the expected impact of the transition in our distribution strategy.
Transportation revenues in the quarter are expected to be down modestly on an organic basis. Overall, we expect sequential improvement in Transportation segment organic growth rates as the year progresses, driven by gradually improving end market conditions and the inclusion of Transporeon in our organic trends, beginning in the second quarter. As Rob mentioned earlier, we are moving to implement a new segment reporting structure that reflects our updated organization and the way we will evaluate our businesses and allocate capital, going forward. Our plan is to publish more details on our new segment reporting structure later in the first quarter, with financials going back two years and the perspective on how our 2024 annual guidance cascades to the new segments. We will have a separate conference call with investors to review that information when it is available.
Rob, I'll turn it back over to you.
