This presentation has been prepared solely for informational purposes and is not intended to serve as the basis for any investment decision. This presentation contains certain forward-looking statements within the meaning of the federal securities laws. These statements may be made as a part of this presentation or by reference the preliminary and final offering memorandum for the offering. Some of the forward-looking statements can be identified by the use of forward-looking words. Statements that are not historical in nature, including the words ‘‘anticipate,’’ ‘‘may,’’ ‘‘estimate,’’ ‘‘should,’’ ‘‘expect,’’ ‘‘plan,’’ ‘‘believe,’’ ‘‘intend,’’ and similar words, or the negatives of those words, are intended to identify forward-looking statements. They also include statements containing a projection of revenues, earnings (loss), capital expenditures, dividends, capital structure or other financial terms. Certain statements regarding the following particularly are forward-looking in nature: ▪ WLFC’s business strategy; ▪ WEST’s business strategy and assumptions used to develop the cash flow models; ▪ future performance, developments, market forecasts or projections; and ▪ WLFC’s projected capital expenditures. All forward-looking statements are based on our beliefs, assumptions and expectations of future economic performance, taking into account the information currently available. These statements are not statements of historical fact. Forward-looking statements are subject to a number of factors, risks and uncertainties, some of which are not currently known and many of which are beyond WLFC’s and WEST’s control, which may cause actual results, performance or financial condition to be materially different from the expectations of future results, performance or financial position, as well as those included in the cash flow models. Our actual results may differ materially from the results discussed in forward-looking statements. Factors that might cause such a difference include, but are not limited to: ▪ the effects on the airline industry and the global economy of events such as terrorist activity; ▪ changes in fuel prices and other disruptions to the world markets; ▪ trends in the airline industry, including growth rates of markets and other economic factors; ▪ risks associated with owning and leasing commercial engines and aircraft; ▪ changes in interest rates and availability of capital to us and to our customers; ▪ our ability to continue to meet our customers’ changing demands; ▪ the market value of engines and other assets in our portfolio; ▪ regulatory changes affecting commercial aircraft operators, aircraft maintenance, engine standards, accounting standards and taxes; ▪ WLFC’s, in its capacity as Servicer, ability to successfully negotiate engine purchases, sales and leases, to collect outstanding amounts due, and to repossess engines under defaulted leases, and to control costs and expenses. In light of these risks, uncertainties and assumptions, you are cautioned not to place undue reliance on forward-looking statements, which speak only as of the date of meeting or as of the date of any document incorporated by reference, as applicable. Such forward-looking statements are inherently uncertain, and actual results may differ from expectations. We are not under any obligation, and we expressly disclaim any obligation, to update or alter any forward-looking statements, whether as a result of new information, future events or otherwise. In this presentation, WLFC presents certain non-GAAP measures, including EBITDA, EBITDA Interest Coverage and similar measures, which are not required by, or presented in accordance with, GAAP. While WLFC believes these are useful metrics, companies use these metrics for differing purposes and they are often calculated in ways that reflect the particular circumstances of those companies. You should exercise caution in comparing the non-GAAP metrics reported by us to such metrics or other similar metrics as reported by other companies. Our non-GAAP metrics have limitations as analytical tools, and you should not consider them in isolation. Under no circumstances is this presentation or the information contained herein to be construed as a prospectus, offering memorandum or advertisement and neither any part of this written or oral presentation nor any information or statement contained herein or therein shall form the basis of or be relied upon in connection with any contract or commitment whatsoever. This presentation does not constitute an offer to sell, or a solicitation of an offer to buy, any securities in any jurisdiction where such an offer or solicitation would be unlawful.
