Forward - looking Statements This presentation contains forward - looking statements that reflect our current expectations and views of future events, all of w hich are subject to risks and uncertainties. Forward - looking statements give our current expectations or forecasts of future events. You can identify these statements by the fact that they do not relate strictly to historical or current facts. You can find m any (but not all) of these statements by the use of words such as "approximates," "believes," "hopes," "expects," "anticipates," "estimates," "projects," "intends," "plans," "will," "would," "should," "could ," "may" or other similar expressions in this presentation. These statements are likely to address our growth strategy, business plans, future industry demand, financial results and product and development pro grams. You must carefully consider any such statements and should understand that many factors could cause actual results to differ from our forward - looking statements. These factors may include assumptions and a broad variety of other risks and uncertainties, including some that are known and some that are not. No forward - looking statement can be guaranteed and actual future results ma y vary materially. Factors that could cause actual results to differ from those discussed in the forward - looking statements include, but are not li mited to: our goals and strategies; our future business development, financial condition and results of operations; the introduction of new product and service offerings; our expectations regarding change s i n our revenues, cost or expenditures; our expectations regarding the demand for and market acceptance of our products and services; our expectations regarding the growth of our customer base, in clu ding consolidated account customers; competition in our industry; government policies and regulations relating to our industry; and assumptions underlying or related to any of the foregoing. These forward - looking statements involve various risks and uncertainties. Although we believe that our expectations expressed in these forward - looking statements are reasonable, our expectations and our actual results could be materially different from our expectations. We describe certain material risks, uncertainties and as sumptions that could affect our business, including our financial condition and results of operations, under the “ Risk Factors” section of the prospectus contained in the Registration Statement. Statistical data referenced in this presentation may also include projections based on a number of assumptions. The Construct ion industry in Hong Kong and demand for civil engineering works may not grow at the rate projected by market data, or at all. Failure of market demand and/or the industry to grow at projected rates ma y have a material and adverse effect on our business and the market price of the ordinary shares. By way of example and without limitation to risks set forth in our prospectus, international trade regul ati on, customs rules, exchange rates, market size of construction industry in Hong Kong and other factors materially affect our business. Furthermore, if any one or more of the assumptions underlying the mark et data are later found to be incorrect, actual results may differ from the projections based on these assumptions. This presentation contains certain data and information that we obtained from third - part y sources that were not independently verified by us. We have engaged Migo Corporation Limited to prepare a commissioned report on the construction industry in Hong Kong. Information and data rel ati ng to the Hong Kong construction industry have been derived from Migo’s industry report, which also includes projections based on a number of assumptions. Any failure of the construction industry to grow at the projected rate may have a material adverse effect on our business and the market price of the ordinary shares. Furthermore, if any one or more of the assumptions underlying the marke t d ata is later found to be incorrect, actual results may differ from the projections based on these assumptions. We base our forward - looking statements on our management’s beliefs and assumptions based on information available to our managem ent at the time the statements are made. We caution you that actual outcomes and results may, and are likely to, differ materially from what is expressed, implied or forecast by our forw ard - looking statements. Accordingly, you should be careful about relying on any forward - looking statements. Except as required under the federal securities laws, we do not have any intention or obligation to update publicly any forward - looking statements after the distribution of this prospectus, whether as a result of new information, future events, changes in assumptions, or otherwise.
