Diesel prices have fluctuated significantly over time, often in parallel to changes in oil prices, and may fluctuate in the future as a result of many factors, including the impact of geopolitical tensions, for example, in connection with the current conflict between Russia and Ukraine and the related economic sanctions. We therefore remain exposed to diesel price volatility, which may result in substantial increases in our operating costs and reduced profits if prices rise significantly.
Through our international operations, we are also exposed to foreign exchange risk arising from currency exposures other than the US Dollar, such as the BRL, NGN, RWF, XAF, XOF, ZAR and ZMW currencies. Any fluctuations in these foreign currency exchange rates could result in a material adverse effect on the cash flow and future profits.
Outstanding balances and advances under certain of our existing credit facilities bear interest at rates which vary depending on certain underlying or reference rates, such as the Secured Overnight Financing Rate, or SOFR, the Chicago Mercantile Exchange (CME) Term SOFR, the London Interbank Offered Rate, or LIBOR, the European interbank offered rate, or EURIBOR, the Nigerian Monetary Policy Rate, or MPR, the Kuwait Interbank Offered Rate, or KIBOR, the Johannesburg Interbank Average Rate, or JIBAR, or the Brazilian interbank deposit rate, or CDI. Increases in such reference rates increase our interest expense, which could have a material adverse effect on our business, prospects, financial condition and/or results of operations. Such increases in interest rates could also have a material adverse effect on our cash flows and our ability to service our debt in the longer term.
In the past, governments have taken, and may in the future take, unprecedented actions in an attempt to address and rectify these extreme market and economic conditions by providing liquidity and stability to financial markets. If these actions are not successful, the return of adverse economic conditions may cause a significant impact on our ability and the ability of our customers to raise capital, if needed, on a timely basis and on acceptable terms or at all.
To the extent that any macroeconomic issues could have a material adverse effect on our or our customers’ business, financial condition, results of operations and/or liquidity, it may also have the effect of heightening many of the other risks described in the “Risk Factors” section of our Annual Report.
Key Financial and Operational Performance Indicators
We believe that revenue growth, Adjusted EBITDA, Adjusted EBITDA Margin, non-discretionary capital expenditure, Recurring Levered Free Cash Flows (“RLFCF”), the number of Towers in our portfolio and Colocation Rate are key measures to assess our financial and operational performance. These measures demonstrate our ability to grow and generate strong positive cash flows over time. Adjusted EBITDA, Adjusted EBITDA Margin, non-discretionary capital expenditure and RLFCF are not measures defined by IFRS. The most directly comparable IFRS measure to Adjusted EBITDA is our profit/(loss) for the period. The most directly comparable IFRS measure to RLFCF is cash flows from operations. Adjusted EBITDA, Adjusted EBITDA Margin and RLFCF are not necessarily comparable to similarly referenced measures used by other companies. As a result, investors should not consider these performance measures in isolation from, or as a substitute analysis for, our results of operations as determined in accordance with IFRS.
Adjusted EBITDA and Adjusted EBITDA Margin
We believe Adjusted EBITDA and Adjusted EBITDA Margin are useful to investors and are used by our management for measuring profitability and allocating resources, because they exclude the impact of certain items that have less bearing on our core operating performance such as interest expense and taxes. We believe that utilizing Adjusted EBITDA and Adjusted EBITDA Margin allows for a more meaningful comparison of operating fundamentals between companies within our industry by eliminating the impact of capital structure and taxation differences between the companies.
We define Adjusted EBITDA as profit/(loss) for the period, before income tax expense/(benefit), finance costs and income, depreciation and amortization, impairment of withholding tax receivables, business combination transaction costs, impairment of property, plant and equipment and related prepaid land rent on the decommissioning of sites, net (profit)/loss on sale of assets, share-based payment (credit)/expense, insurance claims, listing costs and certain other items that management believes are not indicative of the core performance of our business.
We define Adjusted EBITDA Margin as Adjusted EBITDA divided by revenue for the applicable period, expressed as a percentage.
