FORWARD-LOOKING STATEMENTS

This Annual Report and other documents we file with the Securities and Exchange Commission, or SEC, contain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 that involve significant risks and uncertainties. In addition, we may make forward-looking statements in our press releases or in other oral or written communications with the public. These forward-looking statements include, among others, statements about the future development plans of encorafenib and binimetinib; expectations that events will occur that will create greater value for Array; and the potential for the results of current and future clinical trials to support regulatory approval or the marketing success of encorafenib and binimetinib. Because these statements reflect our current expectations concerning future events and involve significant risks and uncertainties, our actual results could differ materially from those anticipated in these forward-looking statements as a result of many factors. These factors include, but are not limited to, the potential that the FDA, EMA or other regulatory agencies determine results from clinical trials are not sufficient to support registration or marketing approval of encorafenib and binimetinib; our ability to effectively and timely conduct clinical trials in light of increasing costs and difficulties in locating appropriate trial sites and in enrolling patients who meet the criteria for certain clinical trials; risks associated with our dependence on third-party service providers to successfully conduct clinical trials and to manufacture drug substance and product within and outside the United States (U.S.); our ability to grow and successfully develop commercialization capabilities; our ability to achieve and maintain profitability and maintain sufficient cash resources; and our ability to attract and retain experienced scientists and management. Additional information concerning these and other risk factors can be found in the Annual Report on Form 10-K, under the caption "Item 1A. Risk Factors." We are providing this information as of the date of this report. We undertake no duty to update any forward-looking statements to reflect the occurrence of events or circumstances after the date of such statements or of anticipated or unanticipated events that alter any assumptions underlying such statements.

MARKET AND INDUSTRY DATA

Unless otherwise indicated, information contained in the Annual Report on Form 10‑K concerning the cancer market, the drug market and our other markets, including our general expectations and market position, market opportunity and market share, is based on information from independent industry analysts and third-party sources and management estimates. Management estimates are derived from publicly available information released by independent industry analysts and third-party sources, as well as data from our internal research, and are based on assumptions made by us based on such data and our knowledge of such industry and markets, which we believe to be reasonable.

We have not independently verified or verified with any independent source any third-party information. In addition, while we believe the market position, market opportunity and market share information included in the Annual Report on Form 10-K is generally reliable, such information is inherently imprecise. Such data involves risks and uncertainties and is subject to change based on various factors, including those discussed under the heading "Item 1A. Risk Factors."
