Matters discussed in this presentation may constitute forward-looking statements. Forward-looking statements are statements other than in respect of historical facts. The words “believe”, “expect”, “anticipate”, “intends”, “estimate”, “will”, “may”, "continue”, “should” and similar expressions usually identify forward-looking statements. Forward-looking statements may include statements regarding: objectives, goals, strategies, outlook and growth prospects; future plans, events or performance and potential for future growth; liquidity, capital resources and capital expenditures; economic outlook and industry trends; energy demand and supply; developments of Galp’s markets; the impact of regulatory initiatives; and the strength of Galp’s competitors. The forward-looking statements in this presentation are based upon various assumptions, many of which are based, in turn, upon further assumptions, including without limitation, management’s examination of historical operating trends, data contained in the Company’s records and other data available from third parties. Although Galp believes that these assumptions were reasonable when made, these assumptions are inherently subject to significant known and unknown risks, uncertainties, contingencies and other important factors which are difficult or impossible to predict and are beyond its control. No assurance, however, can be given that such expectations will prove to have been correct. Important factors that may lead to significant differences between the actual results and the statements of expectations about future events or results include the Company’s business strategy, industry developments, financial market conditions, uncertainty of the results of future projects and operations, plans, objectives, expectations and intentions, among others. Such risks, uncertainties, contingencies and other important factors could cause the actual results of Galp or the industry to differ materially from those results expressed or implied in this presentation by such forward-looking statements. Actual future results, including financial and operating performance; demand growth and energy mix; Galp’s production growth and mix; the amount and mix of capital expenditures; future distributions; resource additions and recoveries; project plans, timing, costs, and capacities; efficiency gains; cost savings; integration benefits; product sales and mix; production rates; and the impact of technology could differ materially due to a number of factors. These include changes in oil or gas prices or other market conditions affecting the oil, gas, and industries; reservoir performance; timely completion of development projects; war and other political or security disturbances; changes in law or government regulation, including environmental regulations and political sanctions; the outcome of commercial negotiations; the actions of competitors and customers; unexpected technological developments; general economic conditions, including the occurrence and duration of economic recessions; unforeseen technical difficulties; and other factors. The information, opinions and forward-looking statements contained in this presentation speak only as at the date of this presentation, and are subject to change without notice. Galp and its respective representatives, agents, employees or advisors do not intend to, and expressly disclaim any duty, undertaking or obligation to, make or disseminate any supplement, amendment, update or revision to any of the information, opinions or forward-looking statements contained in this presentation to reflect any change in events, conditions or circumstances.
