IHS Holding Limited (NYSE:IHS) Q4 2022 Earnings Call Transcript
IHS Holding Limited (NYSE:IHS) Q4 2022 Earnings Call Transcript March 30, 2023
Operator: Good day, and welcome to the IHS Holdings Limited Earnings Results Call for the 3-month and Full Year period ended December 31, 2022. Please note that today's conference is being webcast and recorded. . At this time, I'd like to turn the conference over to Colby Synesael. Please go ahead, sir.
Colby Synesael: Thank you, operator. Thanks also to everyone for joining the call today. I'm Colby Synesael, the EVP of Communications here at IHS. With me today are Sam Darwish, our Chairman and CEO; and Steve Howden, our CFO. This morning, we filed our annual report on Form 20-F for the full year ended December 31, 2022, with the SEC, which can also be found on the Investor Relations section of our website and issued a related earnings release and presentation. These are the consolidated results of IHS Holding Ltd, which is listed on the New York Stock Exchange under the ticker symbol IHS, which compromises the entirety of the group's operations. First, we apologize for having to reschedule our earnings call to today. But as our announcement noted, it was important that we took the extra time to complete our year-end closing process procedures, particularly relating to the integration of recent acquisitions.
Second, and before we discuss the results, I would like to draw your attention to the disclaimers set up at the beginning of the presentation on Slide 2, which should be read in full, along with the cautionary statement regarding forward-looking statements set out in the earnings release and Form 20-F filed as well today. In particular, the information to be discussed may contain forward-looking statements, which, by their nature, involve known and unknown risks, uncertainties and other important factors, some of which are beyond our control that are difficult to predict and, other factors which may cause actual results, performance or achievements or industry results to be materially different from any future results, performance or achievements or industry results expressed or implied by such forward-looking statements, including those discussed in the Risk Factors section of our Form 20-F filed today with the Securities and Exchange Commission, and our other filings filed with the SEC.
We'll also refer to non-IFRS measures that we view as important in assessing the performance of our business. Reconciliation of non-IFRS metrics to the nearest IFRS metrics can be found in our earnings presentation, which is available on the Investor Relations section of our website. And with that, I'd like to turn the call over to Sam Darwish, our Chairman and CEO.
Sam Darwish: Thanks, Colby, and welcome, everyone, to our fourth quarter and year-end 2022 earnings results call. Very strong quarter with 2022 revenue, adjusted EBITDA and RLFCF, all at the high end or above our guidance. The strength was primarily driven by continued secular demand and, to a lesser degree additional power revenue and $4 million for its tailwind versus rates previously assumed in guidance. For the year, we generated revenue of $1.961 billion, adjusted EBITDA of $1.031 billion, an RLFCF of $363 million, with organic revenue growth of 19.5%. We are excited to have crossed the $1 billion adjusted EBITDA mark for the first time ever. We expect this trend to continue, which is reflected in our 2023 guidance that we are introducing today.
Our note guidance includes approximately $40 million of revenue from a onetime cash payment received in the first quarter '23 from our smallest key customer in Nigeria. This was for services we previously provided to them, but had not previously recognized given our revenue recognition policy. Even excluding this payment, though, the midpoint of our revenue guidance implies organic revenue growth of approximately 21%. Skipping to Slide 7. I want to discuss some of our key highlights this past year. Our first full year as a public company. In 2022, we completed 2 acquisitions, including SP5 in Brazil and the MTN portfolio in South Africa. The SP5 acquisition in March added over 2,100 towers, and we now have nearly 7,000 towers in Brazil, making us the third largest independent tower operator in the country.
And as you'll see in our guidance, we expect to triple our BTS program in LatAm this year versus last year. We also continue to make good progress building our neutral host fiber business, I-Systems, with the network now passing 7.5 million homes as of the fourth quarter '22, including 4.5 million with fiber. This position is versus the 6.4 million homes and 3.5 million with fiber when we acquired the network from TIM in November 2021. We expect to make further progress in 2023 towards our goal to pass 10 million homes with fiber by the end of 2026. In total, our LatAm business generated over $125 million of annualized segment adjusted EBITDA in the fourth quarter 2022. In South Africa, our acquisition of the MTN portfolio in May, immediately made us the largest independent tower operator in the country.
As part of that deal, we also agreed to provide power managed services on an additional approximately 7,100 sites for MTN. Given various dynamics in the market, including an unprecedented level of load shedding that has occurred in the country post deal close, we may evaluate additional opportunities to provide power managed services, and we'll update you as appropriate, if necessary. Both LatAm, Brazil, particularly, and South Africa, represent 2 newer markets of scale in our portfolio that provide us outlets for additional growth and opportunities to further diversify our business. Moving on, in 2022, we took initial steps to help improve stock liquidity, including waiving the registered stock offering requirement for the Block A shares in May, which has helped our trading volumes.
With the Block B shares becoming freely tradable in April 2023, and the Block C and D shares becoming freely tradable in October 2023, we believe that volumes may further improve this year, and we continue to evaluate options that we believe will enhance the value of the company. At the same time, we continue to focus on delivering against our publicly stated fundamental objectives and building a track record with investors. During 2022, we also took steps to further strengthen our balance sheet by raising a new 3-year bullet term loan at the group level that we used to repay near-term debt, and we extended our group revolving credit facility maturity to 2025. I'm also pleased to announce today that we've taken additional steps already in 2023 to strengthen the balance sheet by raising a new Naira-based 5-year term loan and 3-year revolving credit facility that we used to repay near-term and amortizing Naira-based debt.
Including our cash position and undrawn debt capacity, we have over $1 billion of capital available with no meaningful maturities due until Q4 2025. Our treasury team was also busy this past year, helping upstream $207 million from Nigeria, including $60 million in December. And we have since upstreamed an additional $15 million in January, as part of the same structure transaction. This compares to the $179 million to be upstreamed in 2021, despite what has been a more challenging environment. In our view, this success in upstreaming reflects our strong relationship with our banking partners as well as the important role our sector plays in the Nigerian economy. Lastly, in October, we announced Project Green, the next phase of our carbon reduction road map.
Under Project Green, we expect to invest $214 million between 2022 and 2024 to connect more sites to the grid and add more batteries and solar solutions to our towers in 6 different markets. This in return is expected to generate RLFCF savings of $77 million by 2025, and generate an attractive 30% IRR. As a reminder, as part of our carbon reduction road map, we committed to reduce our Scope 1 and Scope 2 GHG emissions intensity per kilowatt by 50% by 2030, which, as I've said before, we believe make smart business sense and helps improve the environment in the communities, in which we operate. I'm also pleased to announce that in February, we received an ESG rating by Sustainalytics which further speaks to our focus and commitment to sustainability.
In conclusion, I am very pleased with how we performed in 2022, and the direction our business is heading, as we continue to focus on organic growth, executing on Project Green, risk management, ways to strategically enhance the value of our business and making IHS a place at which our employees are happy and proud to work. With that, I will turn the call over to Steve.
Steve Howden: Thanks, Sam, and hello, everyone. Turning to Slide 9. As Sam mentioned, we're very pleased with how the business performed in FY '22 and Q4 '22, against a challenging macro backdrop throughout the year. You'll see on this slide that our main KPIs have all increased by double-digit percentages in Q4 '22 versus Q4 '21, and we again delivered double-digit growth in revenue and adjusted EBITDA for the year, while the annual RLFCF comparison is impacted by onetime items in each year that I'll discuss shortly. Specifically in Q4, we delivered 27% growth in revenue, 26% growth in adjusted EBITDA and 11% growth in recurring levered-free cash flow in each case driven by both organic and inorganic activity across our markets.
Our adjusted EBITDA margin was 51.8%. For the full year, IHS grew revenue by 24% and adjusted EBITDA by 11%. RLFCF declined by 11% on a reported basis, but was flat excluding the onetime items in each of '22 and '21, as we'll address shortly. Our adjusted EBITDA margin was 52.6% for the year. You'll also see our level of investment in CapEx to grow the business increased by 30% in the fourth quarter and 57% for the year. This is largely due to investment in Project Green, along with increased CapEx relating to I-Systems fiber deployment and network refurbishment on the South African acquisition, during the year. Finally, our consolidated net leverage ratio increased to 3.2x at the end of Q4 versus last year following our 2 acquisitions, but was up slightly versus Q3 2022.
The rescheduling of our results came primarily from the finalization of the complex IFRS 16 lease accounting, in particular, in relation to the South African assets we acquired during 2022, an important area of accounting, although not one that has impacted our key metrics of revenue, adjusted EBITDA, RLFCF or CapEx. Turning to our revenue on a consolidated basis. Slide 10 shows the components of our 24.2% reported consolidated revenue growth for the full year 2022. Organic revenue growth of 19.5% for the year was driven primarily by CPI escalations and power-related revenue as well as lease amendments, FX resets, new colocation and also new sites and fiber deployment. The level of escalations you see reflects our contract protections in the current inflationary environment.
And together with FX resets, offset the negative FX impact by 280 basis points, while the level of power-related revenue reflects the high energy price environment throughout the year, driven largely by the knock-on implications of the Russia-Ukraine conflict. While not material to revenue in 2022, I would also note that we now include the power pass-through revenue we received in South Africa within Power. On the right, you can see the organic growth rates of each of our segments for the full year, whereas the full year segment details are provided in the appendix. Inorganic growth for FY '22 was 9.6%, again, primarily reflecting the South African acquisition in Q2 '22, GTS SP5 in Q1 '22 and I-Systems in Q4 of 2021. Slide 11 shows the components of our 26.6% reported consolidated revenue growth in the fourth quarter.
Organic revenue growth of 23.5% was driven primarily by power-related revenue, CPI escalators, FX resets, lease amendments, new colocation as well as fiber deployment and new sites. For the fourth quarter, the level of escalations, together with FX resets, offset the negative FX impact by 90 basis points in this elevated inflationary environment. And the contribution from power-related revenue is particularly significant given the energy price environment during the year. The right side again shows the organic growth rates of each of our segments, but for the fourth quarter of '22, which I'll talk about shortly. Inorganic growth for the fourth quarter was 10.8%, again, reflecting the acquisitions we've spoken about. On Slide 12, you can see our consolidated revenue, adjusted EBITDA and adjusted EBITDA margins for the fourth quarter and the full year '22.
In fourth quarter, IHS generated $526 million in reported revenue, a 27% increase versus the fourth quarter of 2021, while organic revenue growth was 23.5%, each demonstrating the continued strong top line growth trends of the businesses led by Nigeria and LatAm in particular. Aggregate inorganic revenue was $45 million, equating to nearly 11% growth during the quarter, reflecting the acquisitions we've discussed. For the full year, we delivered nearly $2 billion of revenue, a 24% increase, while organic revenue increased by 19.5%. Aggregate inorganic revenue was $151 million, equating to 9.6% growth, again, reflecting the acquisitions previously discussed. Power-related revenue also made up a larger portion this year. Overall, we continue to grow well in line with our stated objectives of seeking double-digit revenue growth on an annual basis.
Regarding our adjusted EBITDA and adjusted EBITDA margins, in the fourth quarter, adjusted EBITDA of $273 million increased 26% versus the fourth quarter of '21, and adjusted EBITDA margin was 51.8%, down 30 basis points from the fourth quarter of '21. But remember that fourth quarter '21 was prior to the significant energy price rises we saw throughout 2022. For the full year, adjusted EBITDA up slightly more than $1 billion, increased 11% versus the prior year, and adjusted EBITDA margin was 52.6%, down from 58.6% in FY '21. The year-over-year changes in adjusted EBITDA and margin for full year '22 primarily reflect the increase in revenue discussed, partially offset with year-on-year increases in cost of sales, mainly due to higher diesel costs as well as increased SG&A associated with being a public company for a full year in '22 versus 2 months in 2021, and some increased maintenance and repair costs on a larger business.
The changes in adjusted EBITDA also reflect $43 million higher onetime net benefits in FY '21 versus FY '22. This means that adjusted EBITDA would have actually increased by 17% for FY '22, if the onetime benefits in each year were eliminated. Power generation cost of sales increased by $152 million, driven by $147 million diesel increase, primarily due to a 60% increase in the diesel price and a 6.4% increase in consumption in Nigeria. The increased diesel costs in full year '22 were partially offset by a $77 million increase from diesel-linked revenue year-over-year. Also, and I'll discuss this later with respect to our guidance, but we have locked in pricing for a significant portion of our diesel needs through September of 2023, something we have highlighted that we were going to do, on our last two calls.
Finally, as discussed on our recent Project Green announcement in October, we're also increasingly prioritizing alternative sources of power to reduce our dependency on diesel. On Slide 13, we first review our recurring levered-free cash flow, or RLFCF. We generated RLFCF of $97 million in the fourth quarter, an 11% increase versus fourth quarter 2021 due to a combination of factors, including the increased revenue and adjusted EBITDA discussed already, offset in part by increase in net interest paid withholding tax and maintenance CapEx. Our RLFCF cash conversion rate was 35.7%. For the full year, we generated RLFCF of $363 million, an almost 11% decrease versus FY '21, and our RLFCF cash conversion rate was 35.2%, down from 43.8%, with onetime items in each year impacting the comparison.
The year-on-year decrease in RLFCF was driven first by the $43 million onetime higher net benefit to EBITDA in 2021 versus 2022, which drops straight through to RLFCF. Excluding that nonrecurring items in each of 2022 and 2021, our RLFCF would have been flat year-on-year, despite the higher energy and interest rate environment during 2022. RLFCF for 2022 was then impacted by the increased diesel costs, impacting adjusted EBITDA that we've already talked about, as well as our bond financings at the end of 2021, driving an increase of nearly $59 million in net interest paid for the year. The proceeds of these bond issuances supported our South African and Brazilian acquisitions, which only contributed partially to the year's RLFCF results. We also saw higher floating rate interest, in light of the interest rate environment during 2022.
We incurred almost $43 million of additional maintenance CapEx, in part due to owning I-Systems now for a full year versus 2 months in 2021, as well as nearly $30 million more in corporate income taxes and revenue withholding tax, and a $16 million of additional lease and rent payments made versus FY 2021, due to owning a larger business. Turning to CapEx. In the fourth quarter, CapEx of $196 million increased 30% year-on-year, and full year CapEx of $633 million increased 57% versus FY '21. The increase in FY '22 was primarily due to increases in Nigeria in connection with Project Green, on which we spent $104 million during the year, increased CapEx in LatAm following the full 12 months of owning I-Systems in the year, and increased CapEx in South Africa, in connection with the refurbishment of the portfolio we acquired during 2022.
Slide 14 looks at our returns and capital allocation. In FY '22, we continue to focus on driving our returns and delivered a return on invested capital of 9.9% versus 11% in the prior year. Our 2022 ROIC is held down by significant investment in both organic and inorganic growth opportunities during the year, including new site build investment in Nigeria and LatAm and further building our I-Systems in Brazil on the organic side. Regarding the inorganic growth, we closed the MTN South Africa and SP5 acquisitions, but saw any partial contributions in the year from each of these. In terms of capital allocation, you can see that a significant portion of our spend in FY '22 was $736 million related to that acquisition investment, which, as we said, was deployed to enter into South Africa and to build upon our 2020 entry into LatAm, in each case, furthering our diversification strategy.
Moreover, IHS continues to be a leading builder of new sites in our markets, with more than 550 such sites built in Nigeria and more than 250 in LatAm, or primarily Brazil, during the year. Turning to the segment review on Slide 15, and I'll first walk through our Nigerian business. The Nigerian macro situation remains challenging, with the country's sovereign debt rating having been downgraded further in late January. U.S. dollars continue to be difficult to source, although remain available, with FX reserves having decreased to $37.1 billion at the end of 2022 from $38.3 billion in the third quarter of '22. And while the price of oil again slightly moderated Q-on-Q, it remains elevated versus a year ago. And due to the continued increase in premium we are seeing applied to the importation of refined products like diesel into Nigeria, we continue to believe that the ICE gas oil price is the most relevant indicator of diesel pricing we pay.
Looking at ICE gas oil, it was $948 per tonne versus $1,012 per tonne in the prior quarter. Moving to real GDP growth. It expanded by 3.5% in the fourth quarter, bringing the full year 2022 growth rate to 3.1%, while inflation increased to 21.3% this past December versus 15.6% in December '21, bringing the full year 2022 average CPI rate to 18.9%. Importantly, on February 25, Bola Ahmed Tinubu was elected as Nigeria's next President with his inauguration scheduled for May 29, and regional elections have also taken place. Looking ahead, we remain cautiously optimistic by these developments given the statements made by Mr. Tanubu regarding addressing the economic issues facing the country, and we remain in close contact with our key customers, two of which have again recently published healthy top line results in their businesses.
We also continue to work closely with various regulators, our vendors and our local banking partners to continue to best position IHS. All said, we believe the business remains well positioned for continued long-term success and to ensure the near-term macroeconomic challenges. And to this point, our Nigerian business once again delivered strong results in the fourth quarter, tracking well on our key metrics. Q4 '22 revenue of $355 million increased by 18.5% year-on-year on a reported basis and 27% on an organic basis. Top line growth was driven by the usual group of power-related revenue escalations, FX resets, lease amendments, new colocation, fiber and new site deployment. The negative FX impact was $26.5 million. Our tower count grew by 0.8% versus Q4 '21, inclusive of some planned decommissioning.
Our total tenant count increased by 2.3% versus the prior period, and our colocation rate was 1.54x, up from 1.52x in Q4 '21. Lease amendments continue to be a strong driver of growth with these increasing by 15% year-on-year, as our customers added additional equipment to our sites, particularly 4G upgrades. Q4 segment adjusted EBITDA in Nigeria was $206 million, a 12% increase from a year ago, and segment adjusted EBITDA margin was 58%. Let me now briefly summarize the results of our other segments. As our sub-Saharan African segment now reflects the inclusion of our South African business, towers and tenants increased substantially versus fourth quarter '21. Revenue increased by 34%, of which organic revenue grew 9.2% and inorganic grew 33%, driven by the South African acquisition, and FX was a 7.8% headwind.
Segment adjusted EBITDA increased by 45%, driven primarily by the increased revenue coming from the South Africa acquisition, offset by increases in power generation costs, maintenance and security costs and some administrative expenses. Segment adjusted EBITDA margin increased to 56.9% from 52.7% in Q4 2021. In our LatAm segment, towers, tenants revenue and segment adjusted EBITDA are all increased substantially in Q4 '22 due to meaningful inorganic growth, primarily from the GTS SP5 acquisition as well as the I-Systems fiber business. In Brazil, our second largest market with 6,994 towers, macro conditions were relatively stable, as FX rates marginally strengthened, interest rates held steady and inflation decreased. We also note the recent election of Lula da Silva as President of Brazil.
In our LatAm segment, overall, Q4 '22 organic revenue increased 32%, driven by an increase from I-Systems, CPI escalations, new sites and new colocation, with inorganic revenue increasing by 80% from the acquisitions. There was also a positive 7.4% FX impact. Segment adjusted EBITDA also more than doubled with a segment adjusted EBITDA margin of 71.6%. In MENA, towers grew by 9.2% and tenants by the same in Q4 '22. Revenue grew by 16%, including 15% organic revenue growth and segment adjusted EBITDA grew by nearly 20%, in each of these cases, mainly as a result of new sites and the closing of the fifth tranche of the Kuwaiti acquisition in the third quarter of '22. Q4 '22 segment adjusted EBITDA margin was increased to 46.3%. On to Slide 16 and briefly to highlight our KPIs, as of December 31, our tower count was 39,652, up by just over 8,600 towers or almost 28% from the end of 2021, driven largely by the acquisitions mentioned and ongoing new sites in Nigeria, LatAm and SSA.
As you can see in the chart on the top right, collectively, we built nearly 1,200 sites during the year, below our guidance of approximately 1,350, driven primarily by our decision to slow our rural builds in Nigeria, as we shift more of our CapEx to Project Green and some timing issues in LatAm. We'll discuss this further when we discuss our guidance, but we expect to further slow our builds in Nigeria in 2023, while we expect to triple our builds in Brazil. Total tenants grew 26% year-on-year with the colocation rate of 1.48x, down 0.02x versus last year, but up slightly from the third quarter. We continue to point out that lease amendments, which are a significant factor in our Nigerian segment are not included in our colocation rate calculation.
Moreover, as a significant acquirer and builder of towers, we typically add to the denominator period-on-period, even as we continue to lease up our portfolio. 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. Lease amendments increased by almost 17% year-on-year as our customers added equipment to their sites, particularly 4G upgrades in Nigeria, and we are starting to see some small 5G activity in Nigeria, which is early days, but very encouraging. On Slide 17, we look at our capital structure and related items. At December 31, 2022, we had approximately $3.95 billion of external debt and IFRS 16 lease liabilities.
Of the $3.95 billion of debt, $1.94 billion represents our bond financings, and other indebtedness includes $370 million, that we drew down from the $600 million 3-year bullet term loan at IHS Holding Limited level that we entered into in October. That $370 million drawdown was used to repay $280 million of bridge loan that we had and the USD 76 million tranche of the Nigerian senior credit facilities. You will see those Nigerian senior credit facilities dropped from $298 million in Q3 to $191 million in Q4 2022. In the fourth quarter, we saw a small rise in IFRS 16 lease liabilities contained within other indebtedness on Slide 17, from the work that we've been doing on our South African leases. Not reflected in our indebtedness, as it remains undrawn, but we also extended the maturity of our $270 million group revolving credit facility out to 2025, as we announced in November.
And then additionally, and subsequent to these numbers, in January 2023, we entered into an up to NGN 165 billion 5-year term loan and up to NGN 55 billion 3-year revolving credit facility in Nigeria. In connection, we repaid NGN 114 billion of our 2 Nigerian local currency facilities removing significant 2023 amortization. The Nigeria RCF remains undrawn. As you can imagine, we are very pleased to have completed these transactions, including the October bullet term loan, Group RCF extension and the January 2023 Nigerian refinancings, which further derisks the balance sheet and increased our financial flexibility, particularly in light of the tough financing conditions that remain across the globe. We continue to believe the successful outcome is a testament to the strength of our cash flows, our contracts and our history in the credit markets, as well as our relationships with our global banking partners.
Cash and cash equivalents decreased slightly to $514 million at December 31. And in terms of where that cash is held, approximately 6% of the total cash was held in Naira at our Nigerian business, as we have been using excess cash to support Project Green and for upstreaming. Most of the raining cash was held in U.S. dollars at the group level. And as Sam mentioned earlier, in 2022, we upstreamed a total of $207 million from Nigeria at an average rate of approximately NGN 550 versus $179 million at a rate of approximately NGN 480 in 2021. And we've just upstreamed another $15 million in January of this year. One further point to make is that IHS does not have any relationship with Silicon Valley Bank, any other U.S. regional banks or Credit Suisse.
Consequently, from all of these moving elements at the end of Q4 2022, our consolidated net leverage was approximately $3.4 billion, with a consolidated net leverage ratio of 3.2x, up slightly from September. This is at the low end of our net leverage target range of 3 to 4x and further demonstrates our strong balance sheet. You'll see that as of December 31, 78% of our debt was linked to hard currencies with a fixed floating ratio of 65% to 35%, and our weighted average cost of debt was 8.6%. Moving to Slide 18. We are introducing 2023 guidance that includes revenue in the range of $2.19 billion to $2.22 billion, adjusted EBITDA in the range of $1.2 billion to $1.22 billion. RLFCF in the range of $430 million to $450 million and total CapEx in the range of $610 million to $650 million.
As Sam mentioned, guidance includes an approximate $40 million of revenue from a onetime cash payment received in the first quarter from our smallest key customer in Nigeria. This was for services we previously provided to them, but had not previously recognized given our revenue recognition policy. However, even excluding this payment, the midpoint of our revenue guidance implies organic revenue growth of approximately 21%. Guidance also includes approximately $25 million in power pass-through revenue in South Africa compared to $2 million this past year, as we work with MTN to move various utility billing arrangements under our name. I do want to caution that timing of such move is difficult to predict and could be delayed relative to what we've assumed, although this would have no impact on adjusted EBITDA or RLFCF.
Total CapEx guidance for 2023 includes approximately $30 million that we had expected to spend in 2022, but for timing reasons has shifted into this year. CapEx also includes $90 million to $100 million for Project Green, which includes our initial $82 million forecast, plus a $6 million carryover from 2022, and upwards of approximately $10 million to potentially pull forward CapEx, we would otherwise spend in 2024, as our overall projections for CapEx savings and returns remain unchanged. I also want to point out, again, that we have locked in pricing for a significant portion of our diesel needs in Nigeria through September 2023, which, in turn, will provide greater visibility to our costs. For the year, we expect to build approximately 1,200 towers, which is just slightly more than the amount we built in 2022.
As I already mentioned, this includes a notable drop in Nigeria, as we pull back on new site builds as we shift our focus to Project Green, but also includes a tripling of towers in Brazil. I also want to point out that in Nigeria, we expect to rationalize approximately 750 towers this year, that are occupied by our smallest key customer. This will not have an impact on revenue, but will reduce our operating costs, and hence, is beneficial to IHS. On Slide 19, on top, you can see revenue by reporting currency for fourth quarter and the full year, whereas on the bottom, we provide the breakout of revenue based on contract split. The right side shows the average annual FX rate assumptions used in our 2023 guidance. Finally, on Slide 20, we provided the estimated full year financial impact of theoretical 10% devaluation in the Naira would have on our financials.
While our 2023 guidance already assumes a devaluation from approximately today to by the end of 2023 and an average for the full year. We've shown here the impact of a 10% devaluation beyond what we've assumed in guidance. For example, the figures in the middle of the page, including the $47 million impact to revenue, provide a sense of what the 12-month run rate impact would be, using our 2023 expectations. However, as you'll see on the right side, the illustration in the middle of the page excludes an incremental approximately $20 million impact that would occur in the quarter devaluation actually happens, assuming the devaluation was to occur on the first day of the quarter. This represents the maximum lag that would occur between the devaluation and when most of our FX resets would start to kick in, in the next quarter.
As a reminder, the vast majority of our resets are either quarterly or monthly. Overall, we feel we are well positioned to absorb a potential devaluation, and believe that in the longer run, such an event will be positive for the country and for us. This 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.
