Thank you, Sam, and hello to everyone. Turning to Slide 10. As Sam mentioned, the business performed well in Q1 2022. Here, you can see that our top KPIs have all increased versus Q1 2021, driven by both organic and inorganic growth across the market.
In Q1 versus last year, we delivered double-digit growth in consolidated revenue, adjusted EBITDA and recurring levered free cash flow. And our adjusted EBITDA margin was 54.9%. As I will discuss shortly, our level of investment in CapEx to grow the business increased by 24% in the first quarter. And our consolidated net leverage ratio increased only slightly versus the prior year despite the significant inorganic activity, and that really given our high levels of cash generation.
Slide 11 shows the components of our 23.4% reported consolidated revenue growth. Organic revenue growth of 21.5% in Q1 was driven primarily by escalators, power indexation contained within other, FX resets and lease amendments for the most part, with the escalators and FX resets together more than offsetting the negative FX impact of 3.4%. Inorganic growth was 5.3% in the quarter, primarily reflecting the Skysites and Centennial Colombia acquisitions in Q1 last year, Centennial Brazil in Q2, and I-Systems in Q4, all of last year.
Turning to the segment review on Slide 12. I'll first go through our Nigeria business and then the other segments. The Nigerian macro environment in Q4 last year saw a slight improvement Q-on-Q with real GDP growth expanding by just under 4%, bringing the full year 2021 growth rate to 3.4%. Inflation decreased to 15.9% this past March versus 18.2% in March last year. The NAFEX currency rate ended the quarter at NGN 417 to the dollar, whilst FX reserves marginally decreased to $39 billion from $40 billion at December 31.
The Brent crude oil price stood at approximately $101 per barrel at the end of Q1 '22, up from $61 in the same period last year. Telecommunications remains an important part of the Nigerian economy, accounting for around 12.6% of GDP in the last quarter of last year. Against this backdrop, our business once again delivered strong results in the first quarter, tracking well on our key metrics. Top line growth continues to be driven by those escalations, the FX resets, lease amendments, colocation, new sites, and with power indexation and fiber growing factors as well.
Our tower count grew by over 200 sites or 1.5%, inclusive of some planned decommissioning, and we suffered de minimis churn only. Our total tenant count increased by 4.3%, and our colocation rate was up at 1.52x. Lease amendments continue to be a strong driver of growth with those increasing nearly 43% year-on-year as our customers continue to add additional equipment to our sites, particularly 4G upgrades.
This improved operational performance is reflected in our Nigerian financial results. Q1 '22 revenue of $321 million increased nearly 23% year-on-year and 27% on an organic basis. Q1 '22 adjusted EBITDA in Nigeria was $203 million, an almost 13% increase from a year ago. And adjusted EBITDA margin was 63.3%. The year-on-year increase is primarily due to the revenue growth, but partially offset by an increase in power generation costs of $38 million and an increase in regulatory permit costs of $2 million. Of this $38 million power generation cost increase, $32 million is related to diesel price, with the balance related to growing consumption from more tenants and towers.
Let me now summarize the results of our other segments. In SSA, towers were up almost 4% in the quarter, while tenants decreased 1.5% due to churn of nonrevenue-generating sites during 2021 that we previously disclosed. Q1 '22 revenue increased 3%, while adjusted EBITDA decreased by 3%, driven by increased power generation, regulatory permits and administrative costs that offset the increased revenue. The adjusted EBITDA margin was 54.9%.
As Sam mentioned a few months ago, our LatAm segment reflects meaningful inorganic growth, which continued this quarter with the GTS SP5 acquisition. In Brazil, our second largest market with 6,786 towers, macro conditions were somewhat mixed as FX rates appreciated and inflation stabilized, but we have seen interest rates rising materially in Brazil.
In our Lat Am segment, overall, towers and tenants almost doubled due to the acquisitions. And Q1 revenue and adjusted EBITDA each essentially tripled, with an adjusted EBITDA margin of 70.8%. Note that these results include a full quarter from I-Systems, which closed in November, but only a 2-week contribution from the GTS SP5 assets, which we acquired in the third week of March this year.
In MENA, towers grew by nearly 23% and tenants by nearly 24% in the quarter and revenue by 28%, with adjusted EBITDA growing by 18%. In all of these cases, mainly as a result of closing further tranches of the Kuwait acquisition as well as some new site construction. The quarter adjusted EBITDA margin was 42%.
Turning to Slide 13. I'll dig a little deeper into the KPIs that drove the revenue gains I just mentioned. As of the end of the quarter, our tower count was over 33,000, up almost 14% from this time last year or an increase of 4,000 towers. This was driven largely by the acquisitions in LatAm, particularly the GTS deal, which added 2,115 towers in Brazil as well as the ongoing new site construction programs there and the new site activity in Nigeria and SSA. Collectively, these new build programs accounted for most of the over 200 towers built during the first quarter, including 100 in Nigeria, 41 in LatAm and 39 in SSA.
Total tenants grew just over 12% year-on-year to 49,643 with the colocation rate at 1.49x, down by 0.02x versus last year. Two things we continue to point out related to the colocation rate, which we define as total tenants across the portfolio divided by total towers. Firstly, lease amendments, which we know are a significant factor in Nigerian segment, these are not included in our colocation rates. And secondly, when you're a significant acquirer and builder of towers as we are, then you're typically adding to the denominator period-on-period, even as we continue to lease up our portfolio.
For example, our recent GTS acquisition in Brazil had a colocation rate of 1.4x. And therefore, lower at inception than our overall portfolio average. We continue to see no reason why we can't get to 2x or greater on our overall portfolio over the long term, and our more mature portfolios of towers are at or above that rate already. Lease amendments increased by approximately 40% year-on-year as our customers added equipment to their sites, as we mentioned, particularly 4G.
On Slide 14, you can see our consolidated revenue, adjusted EBITDA and adjusted EBITDA margins. In the quarter, IHS delivered 20% plus reported in organic growth from a revenue perspective as Q1 reported revenue of $446 million grew by 23% and organic revenue growth was nearly 22%. It was another strong quarter to top line growth, led by Nigeria and LatAm. Overall, we continue to grow well in line with our stated objectives of seeking double-digit revenue growth on an annual basis.
In addition, as we have shown the quarterly revenue trend here, I would point out the $24 million of additional nonrecurring revenue from Q2, in last year in 2021, both as it relates to what the quarterly growth trend would look like without that revenue and with respect to the comparison that we'll be reporting next quarter on our Q2 call.
Regarding our adjusted EBITDA and adjusted EBITDA margins this quarter, we were pleased with our double-digit growth on a reported basis. Adjusted EBITDA in the quarter of $245 million, a 14% increase, and adjusted EBITDA margin was 54.9%, down from 59.5% last year, although as we had forecasted.
The increase in adjusted EBITDA primarily reflects the increase in the revenue we've discussed, and partially offset with year-on-year increases in power generation costs as well as SG&A associated with being a public company. Power generation costs increased by $39 million across the group, primarily in our Nigerian segment, due to an 86% higher U.S. dollar-denominated cost of diesel as well as a 17% year-on-year increase in overall consumption resulting from increased tenant and lease amendment activity.
However, these increased costs were partially offset by a $12 million increase from power indexation revenue year-over-year. We continue to mitigate the pressure of increase in oil prices by forward buying where possible, looking at both international and local suppliers as well as prioritizing alternative sources of power to reduce the dependency on diesel. As a reminder to all, we have previously guided to an increase in the assumption on oil per barrel cost in Q2 2022, rising to $120 per barrel. So this may well flow through into our adjusted EBITDA and margin next quarter, and you'll see those when we report in the summer.
On Slide 15, we review our recurring levered free cash flow, which we report in a manner consistent with our U.S. peers. We generated RLFCF of $87 million in the quarter, an increase of $16 million or 23% versus last year, primarily due to a combination of factors, i.e., the increase in revenue and EBITDA as well as decrease in interest paid due to a change in timing of bond coupon payments post our November '21 bond refinance. Other factors include slightly higher maintenance CapEx Q-on-Q and higher taxes due to expiring tax credits. Our RLFCF conversion rate was 35.6%, up by more than 250 basis points year-on-year.
In terms of CapEx, in Q1, CapEx of $117 million increased 24% year-on-year, primarily due to increases in connection with the I-Systems business that we acquired in November as well as increased new site CapEx in SSA and a bit of offset from a decreased amount of CapEx in Nigeria relating to our fiber business and new site CapEx. As discussed on our 2 most recent earnings calls, we have slightly underspent in terms of CapEx during the quarter as a result of the global supply chain issues rippling across our markets.
Similar to companies around the world, we've seen the slowdown in the supply chain continue into this year, which we're trying to mitigate by ordering equipment earlier, in some cases, 1 to 3 months earlier. As previously mentioned, financially speaking, this impact is small at the moment and has been factored into our guidance for FY '22, noting, however, the continued uncertain macroeconomic world in which we live at the moment.
On Slide 16, we look at our capital structure and related items. And at the end of the quarter, we had approximately $3.1 billion of external debt and IFRS 16 lease liabilities, up slightly from the year-end 2021. Of the $3.1 billion of debt, $1.94 billion represents our bond financings, which include the new $500 million 5.625% senior notes and the $500 million 6.25% senior notes, in addition to our original 2027 bonds that remain outstanding. Also approximately $365 million are senior credit facilities at our Nigeria segment.
Our undrawn group revolving credit facility remains at $270 million. Cash and cash equivalents decreased to $509 million at the end of the quarter, primarily due to the close of the GTS SP5 acquisition. In terms of where that cash is held, approximately 35% of that total was held in Naira at our Nigerian business, and most of the remaining cash was held in U.S. dollars at group level.
In terms of upstreaming cash, we do intend to disclose the amount we upstream each year on our 4Q earnings call. However, given the magnitude of what we've done to date so far this year, we're disclosing that we have already sourced and upstreamed over $100 million in Nigeria, including post the quarter end. This upstream, once complete, will satisfy all U.S. dollar debt obligations for 2022. The conversion rate was at a premium to the current FX rate.
Moving on, at the end of Q1 '22, our consolidated net leverage was approximately $2.55 billion, with consolidated net leverage ratio of 2.5x. However, on a pro forma basis, assuming the closing of the MTN South Africa acquisition and the related financings, that ratio would increase to approximately 3x, still at the low end of our net leverage target range of 3 to 4x and further demonstrating the strength of our balance sheet.
Moving to Slide 17 and guidance. You can see that we're raising our FY '22 guidance to reflect the transaction in South Africa. Even when we exclude it, we are now tracking towards the higher end of our initial revenue and EBITDA guidance, driven principally by continued solid execution and FX gains. Specifically, guidance now includes approximately $80 million of revenue, $45 million of adjusted EBITDA and $45 million of CapEx for the pending South Africa transaction, assuming a June 1 close, i.e., a 7-month contribution in 2022.
This includes the acquisition of approximately 5,700 towers as well as the provision of managed services to an additional 7,000 sites that are located on towers owned by third parties. Note, however, that we have adjusted the financial impact relative to the figures highlighted when we first announced the deal in November to now exclude any revenue from grid pass-through on the over 7,000 managed service sites and this is staying with MTN. And any revenue from grid pass-through on the approximately 5,700 towers being acquired, given the difficulty in predicting the timing in which those utility contracts will be transferred to IHS.
To be clear, the pass-through associated revenue on this latter 5,700 acquired sites will indeed come into our revenue and costs, and we will update you on progress through the quarters. However, it's important to note that given these factors relate to power pass-through, they have 0 impact on EBITDA. So as the adjusted EBITDA guidance we've given for South Africa is not expected to change for these items, whereas revenue could be adjusted upwards later this year. Finally, on South Africa, the guidance also reflects current FX rates.
In terms of LatAm, the guidance reflects the March 17 flows of the GTS portfolio, which contributed $1.7 million of revenue and $1.6 million of adjusted EBITDA in the first quarter this year, whereas previous guidance had assumed an April 1 close. Moreover, guidance continues to exclude any contributions regarding our commercial rollout in Egypt.
Other items to highlight as it relates to guidance are the incremental $23 million of interest costs in '22 following our last year bond transaction as well as the nonrecurring items from FY '21 mentioned a few moments ago, as you're thinking about the comparison to this year. This will be particularly evident next quarter, so Q2, when looking at year-on-year comparisons. For example, we expect organic revenue growth to be closer to approximately 10% next quarter, given the one-offs we reported in Q1 of last year, Q1 of 2021, but to rebound back again into the high teens in the second half of this year.
Taking all of this into account, we believe revenue for the current financial year will now range between $1.875 billion and $1.895 billion on a reported basis, which represents a 19% increase at the midpoint of the range versus last year and approximately 15% organic growth. Key drivers of this include our organic growth programs in all of our markets and particularly our projections for new site growth in Nigeria and Brazil, as you see outlined on the page, as well as, of course, the contribution from I-Systems, GTS in Brazil and MTN assets in South Africa.
In terms of adjusted EBITDA, we're now projecting to range between $1.005 billion and $1.025 billion. And again, just to remember that the EBITDA forecast will continue to include an oil price assumption of $120 per barrel for Q2 through Q4.
With respect to RLFCF, we continue to project it to range between $310 million and $330 million. Here, the key point to remember is we're carrying that $23 million of increased interest costs, and we are cautious on the wider interest rate environment around the world impacting our interest rates. The South Africa transaction does have a positive impact on RLFCF, notwithstanding additional interest from debt financing. But we're cautiously retaining our RLFCF guide and we'll assess this performance over the coming quarters. Also, clearly, oil price impact drops all the way through into RLFCF.
Finally, on CapEx, we're now expecting to spend $545 million to $585 million on total CapEx this year, the difference being now the inclusion of discretionary and nondiscretionary CapEx associated with our South African transaction. We continue to monitor the ongoing supply chain pressures closely, which could impact projected CapEx this year, and will provide relevant updates as appropriate.
Then finally, in terms of sensitivities. Slide 18, we discuss the key energy costs and FX sensitivities regarding the guide. And with respect to oil, the guidance continues to assume that oil price assumption of $120 per barrel for Q2 through Q4. To remind you, the price of oil averaged $101 in Q1 and has subsequently increased in Q2 2022. Consequently, we believed it prudent to continue the $120 assumption for the remainder of the year. But clearly, things will evolve, and we'll update you quarterly on that metric.
On Slide 19, we discuss how FX impacts our business. On the top, you can see revenue by reporting currency, whereas on the bottom, we provide the breakout of revenue based on contract split. To those who may be less familiar, recall that while we are paid in local currency in each of our countries in which we operate, in certain situations, portions of the contracts are linked to hard currencies such as the U.S. dollar or euro, where the amount the customer pays us in local currency adjusts based on the exchange rate with the associated hard currency. These structures help protect against FX devaluation, the impact of which is reflected in our FX reset component in our organic revenue breakup. Also, please be aware that you'll see those percentages change next quarter as there is not a hard currency component to our contract structures in South Africa.
And then lastly, on Slide 20, to highlight the cost of diesel is reflected in our cost of goods sold and equated to $76 million in the first quarter this year, whereas $27 million of revenue was linked to diesel through power indexation clauses that was passed through to customers. Importantly, we believe we have an opportunity to further reduce our reliance on diesel and take costs out by adding more renewable solutions, and therefore, improving margins. We're currently examining these possibilities as part of our development of the carbon reduction plan, which Sam spoke about earlier, named Project Green. And we're looking forward to updating you on this front later this fall.
And that now brings us to the end of our formal presentation. We thank you for your time today. And operator, please now open the line for questions.
