Rod Smith
Executive Vice President, Chief Financial Officer and Treasurer at American Tower
Thanks, Tom. Good morning and thank you for joining today's call. As you saw in our press release, we are off to a solid start to the year with performance exceeding our initial expectations across many of our key metrics. Before diving into the results and the revised outlook for 2023, I'll start with a few highlights from the quarter. First, despite ongoing macroeconomic volatility, strong demand trends continue to drive favorable leasing and growth across our global footprint, which is a testament to the resiliency and stability of our business. In Q1, we posted consolidated organic tenant billings growth of over 6%, our highest rate since 2017 and in over 300 basis point acceleration as compared to-Q1 of 2022. This includes growth through colocations and amendments of over 5%, our highest in three years, as carriers continue to leverage our leading macro tower portfolio to aggressively rollout their networks to meet customer demand.
Organic leasing growth was further complemented by another quarter of strong new build volumes as we continue to leverage our scale and capabilities to attract accretive development opportunities from our leading customers across our international business. Finally, we had another record quarter of leasing from CoreSite continuing the momentum from what was a record breaking 2022 and exceeding our initial underwriting plan.
Complementing our solid top-line trends, our focus on cost management, combined with the inherent operating leverage in the tower model drove margin expansion of approximately 270 basis-points as compared to Q1 of last year to 63.7% with the benefits being more noticeable, given the absence of material M&A.
Going-forward, we'll continue to manage our business with cost discipline, maximizing the profitability of our strong reoccurring organic growth profile. Next, we accessed the debt capital markets, successfully issuing $1.5 billion in unsecured notes and $1.3 billion in secured notes at attractive terms. Proceeds from these offerings more than cover our Q1 maturities and the remainder together with the proceeds from various strategic initiatives, including the sale of the Mexico fiber business, were used to pay-down floating-rate debt. As a result, we've reduced our floating balance by nearly $800 million year to-date, now representing slightly over 20% of our debt structure. We'll continue to evaluate opportunities to further manage this balance over the course of the year.
Finally, we continue to have constructive discussions with potential investors as we assess our strategic options for our India business. We remain focused on executing an outcome that maximizes value and optimizes our global portfolio mix and the risk-adjusted return profile for American Tower and its stakeholders. As we move forward, we will keep our investors informed of any new developments.
With that, please turn to Slide 6, and I'll review our property revenue and organic tenant billings growth for the quarter. As you can see Q1 consolidated property revenue growth was over 4% and approximately 7% on an FX neutral basis over the prior year period. This included U.S. and Canada property revenue growth of over 4%, international growth of over 3% or nearly 9% excluding the impacts of currency fluctuations and approximately 10% growth in our U.S. data center business.
In the quarter, we benefited from accelerated decommissioning related settlements in Latin-America, totaling approximately $39 million. Partially offset by Vodafone-Idea or VIL, revenue reserves of approximately $33 million, representing a modest improvement to payment trends as compared to the second half of 2022.
Moving to the right-side of the slide, organic tenant billings growth was a significant contributor to our overall revenue growth, standing at 6.4% on a consolidated basis, which as I mentioned was our highest quarter since Q3 of 2017. In our U.S. and Canada segment, organic tenant billings growth was 5.6% and nearly 7% absent Sprint related churn, including a record quarter of co-location and amendment growth contributions of nearly $60 million. a nearly 65% increase as compared to the growth reported in Q1 of 2022. Growth modestly exceeded our expectations, driven by some delays in churn, which we still anticipate to occur in the year and to a lesser extent new business upside.
Similarly, our international operations experienced improvements across nearly all reported segments, generating organic tenant billings growth of 7.5% in over 180 basis point acceleration from Q4 of 2022, which includes the benefits of CPI-linked escalator commencements across various contracts. Africa generated its highest quarter on record with organic tenant billings growth of 12.1% including escalator contributions of over 10% and a continuation of solid new business of nearly 7%. Growth in the quarter benefited from some delays in previously communicated carrier consolidation driven churn, which we still expect to occur in the year.
Turning to Europe, we saw a growth of 8.2%, including over 6% from escalations, demonstrating our ability to monetize on CPI-linked escalators across the vast majority of our portfolio in the region. In Latin-America, we saw growth of 6.1%, which includes relatively consistent escalator and new business growth, partially offset by the continued elevated churn as we've highlighted on past calls. Churn in the quarter was favorable relative to our initial expectations as the decommissioning events have been slightly delayed to later in the year.
Lastly, in Asia-Pacific, we saw growth of 3.4%, demonstrating steady improvement over the past three quarters. This growth acceleration was mainly driven by co-location and amendment contributions as carriers ramp-up 5G deployments. Organic tenant billings growth was further complemented by the construction of over 1,300 sites in the quarter, representing our 11th consecutive quarter of exceeding 1,000 sites, primarily in Africa and Asia-Pacific as carriers continue to invest in their network coverage and densification needs across the regions. Initial returns remained solidly in the double digits with Q1 constructed sites yielding nearly 14% on day one.
Turning to Slide seven, adjusted EBITDA grew nearly 9% to approximately $1.8 billion or nearly 10% on an FX neutral basis for the quarter. As I mentioned in my opening remarks, adjusted EBITDA margin demonstrated in approximately 270 basis point improvement year-over-year to 63.7% and still in over 190 basis point improvement when normalizing both periods for VIL related revenue and bad debt reserves in India. This margin expansion was achieved through a continued focus on cost controls, allowing for approximately 100% conversion of revenue to adjusted EBITDA growth. Again on a normalized VIL basis and driving cash SG&A as a percent of total property revenue down by approximately 50 basis points year-over-year to approximately 7.1% for the quarter.
Moving to the right-side of the slide, attributable AFFO growth was 1.5% while roughly flat on a per share basis, which includes financing cost headwinds of around 7.5% and 9.5% against attributable AFFO and attributable AFFO per share growth respectively, primarily driven by the rise in rates over the past year.
Let's now turn to our revised full-year outlook. As mentioned earlier, we had a strong first quarter, outperforming our initial expectations across the majority of our key metrics. While we are excited about the results to-date in the sustainable demand trends that underpinned our performance, we have largely kept core in-full year assumptions consistent to our prior guide, given our early position in the year in some of the timing benefits. I alluded to earlier. This approach for our Q1 guidance is relatively consistent to past years. This also includes our assumptions around VIL related revenue reserves, which we've held at $75 million for the year.
As noted earlier, we did record approximately $33 million in VIL reserves in Q1 with the guide implying an improvement for the duration of the year, notably in the back-half. This assumption is supported by certain factors that we've considered in our risk assessment, including the customers contractual obligations for 2023, our latest conversations with VIL management where they've committed to meet these contractual obligations, and a demonstrated improvement in payments by the customer in Q1 relative to the second half of 2022.
Key updates to our revised outlook includes the impacts from the recent sale of the Fibre business in Mexico, together with the upside from FX derived using our standard methodology in several small adjustments below EBITDA at the attributable AFFO level.
With that let's dive into the numbers. Turning to Slide 8, we are reducing our expectations for property revenue by approximately $20 million versus our prior outlook, driven by $45 million related to the sales of the Fibre business in Mexico, partially offset by $25 million associated with the positive impact of FX.
Moving to Slide 9, we are reiterating our prior outlook expectations for organic tenant billings growth across our regions, and we'll continue to assess the positive momentum coming from our strong first quarter as we work further into the year.
Moving on to slide 10, we are reiterating our adjusted EBITDA outlook with a decline of approximately $25 million related to the Mexico fiber sale, offset by $25 million from positive impacts of FX.
Turning to slide 11, we are raising our expectations for AFFO attributable to common stockholders by $20 million at the midpoint and approximately $0.05 on a per share basis. Moving to the midpoint to $9.65 per share. Updates to our expectations, aside from FX, include the cash adjusted EBITDA reduction driven by the Mexico fiber sale offset by favorable net interest, in part due to the use of the sale proceeds to pay down debt in some cash tax savings.
On an isolated basis, the Mexico fiber sale resulted in a $15 million decline to attributable AFFO as compared to our prior outlook midpoint.
Moving on to slide 12, I'll review our balance sheet and capital allocation priorities for 2023. Beginning on the left side of the slide, our capital allocation priorities for 2023 remain consistent with our prior outlook, which includes approximately $3 billion towards our common dividend subject to Board approval, representing 10% growth year-over-year on a per share basis.
In addition, our capex outlook midpoints remain unchanged. Across all categories and support our initial plans to construct approximately 4,000 new sites across our international footprint.
Moving to the right-side of the slide, and as I highlighted earlier, we further strengthened our investment grade balance sheet in the first three months of the year extending our average maturity profile to nearly six years, while reducing our floating rate debt balance to slightly over 20%. Additionally, we closed the quarter with net leverage of approximately 5.2 times, well on-track towards our deleveraging target of 3 times to 5 times. Consistent with our past remarks. We remain focused on driving shareholder value through our growing dividend and accretive capex program, while strengthening our balance sheet through deleveraging, maximizing liquidity, managing a diverse pool of capital sources in an ongoing assessment of market conditions to potentially further term out floating-rate debt and extend our maturity profile.
Turning to slide 13 and in summary, Q1 was another strong quarter across our business with incremental steps taken towards strengthening our balance sheet. Underpinned by sustained demand trends across our global footprint, our leading portfolio of communications infrastructure assets generated accelerating leasing growth, while our capabilities as an operator and partner continue to afford us opportunities to deploy accretive capital towards high-yielding development projects. We believe we are well-positioned to drive compelling growth supported by attractive secular trends across our global footprint and deliver solid returns to our shareholders over the long-term.
With that, operator. We can open the line for questions.
