CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This Current Report contains certain statements that may constitute “forward-looking statements” within the meaning of Section 27A of the Securities Act, and Section 21E of the Exchange Act. Forward-looking statements include, but are not limited to, statements that refer to projections, forecasts or other characterizations of future events or circumstances, including any underlying assumptions. The words “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “intends,” “may,” “might,” “plan,” “possible,” “potential,” “predict,” “project,” “seek,” “should,” “target,” “would” and similar expressions may identify forward-looking statements, but the absence of these words does not mean that a statement is not forward-looking. Forward-looking statements may include, for example, statements about the ability of Lionsgate Entertainment Corp. (“Lionsgate”) to effectuate the separation of Lionsgate Studios Corp. (“Lionsgate Studios”) and the STARZ Business of Lionsgate (the “Separation”); the benefits of the Separation; changes in Lionsgate’s or Lionsgate Studios’ strategy, future operations, financial position, estimated revenues and losses, projected costs, prospects, plans and objectives of management. These forward-looking statements are based on information available as of the date of this release, and current expectations, forecasts and assumptions, and involve a number of judgments, risks and uncertainties. Accordingly, forward-looking statements should not be relied upon as representing Lionsgate’s or Lionsgate Studios’ views as of any subsequent date, and neither Lionsgate nor Lionsgate Studios undertakes any obligation to update forward-looking statements to reflect events or circumstances after the date they were made, whether as a result of new information, future events or otherwise, except as may be required under applicable securities laws. Lionsgate and Lionsgate Studios cannot give any assurance that either of them will achieve its expectations. You should not place undue reliance on these forward-looking statements. As a result of a number of known and unknown risks and uncertainties, Lionsgate’s or Lionsgate Studios’ actual results or performance may be materially different from those expressed or implied by these forward-looking statements. Some factors that could cause actual results to differ include: (i) the timing to the proposed Separation; (ii) the outcome of any legal, regulatory or governmental proceedings that may be instituted against Lionsgate or Lionsgate Studios or any investigation or inquiry in connection with the Separation or otherwise; (iii) the ability to recognize the anticipated benefits of the Separation; (iv) unexpected costs related to the Separation; (v) the possibility that Lions Gate may be adversely affected by other economic, business, and/or competitive factors; (vi) operational risks; (vii) litigation and regulatory enforcement risks, including the diversion of

management time and attention and the additional costs and demands on Lionsgate’s or Lionsgate Studios’ resources; and (viii) other risks and uncertainties indicated from time to time in the annual report on Form 10-K of Lionsgate filed with the Securities and Exchange Commission on May 30, 2024 (the “Lionsgate Form 10-K”) and the current report on Form 8-K of Lionsgate Studios filed with the Securities and Exchange Commission on May 14, 2024 in connection with the consummation of the Business Combination (the “Studios Form 8-K”) including those under “Risk Factors” in the Lionsgate Form 10-K and Studios Form 8-K, and in the other periodic reports and other filings of Lionsgate and Lionsgate Studios with the Securities and Exchange Commission.
