This prospectus, any applicable prospectus supplement and any free writing prospectus filed by us do not constitute an offer to sell or the solicitation of an offer to buy any securities other than the registered securities to which they relate, nor do they constitute an offer to sell or the solicitation of an offer to buy securities in any jurisdiction to any person to whom it is unlawful to make such offer or solicitation in such jurisdiction.

For investors outside of the United States, neither we nor any selling securityholders have done anything that would permit the offering, possession or distribution of this prospectus in any jurisdiction where action for that purpose is required, other than in the United States. You are required to inform yourselves about and to observe any restrictions relating to the offering, possession or distribution of this prospectus outside of the United States.

This prospectus is a part of a registration statement that we filed on Form S-3 with the Securities and Exchange Commission (the “SEC”) under a “shelf” registration process. Under this shelf registration process, we may, from time to time, offer and sell, either separately or together, common stock, preferred stock, depositary shares or debt securities in one or more offerings.

Each time we offer and sell securities, we will provide a prospectus supplement or other type of offering document or supplement (together referred to herein as a “prospectus supplement”) that will contain specific information about the terms of that offering. Any applicable prospectus supplement or free writing prospectus may also add, update or change information contained in this prospectus, and accordingly, to the extent inconsistent, information in this prospectus is superseded by the information in such applicable prospectus supplement or free writing prospectus. You should read this prospectus and any applicable prospectus supplement together with the additional information described under the heading “Where You Can Find More Information.”

This prospectus contains summaries of certain provisions contained in key documents described in this prospectus. All of the summaries are qualified in their entirety by the actual documents, which you should review before making your investment decision. Copies of the documents referred to herein have been filed, or will be filed or incorporated by reference as exhibits to the registration statement of which this prospectus is a part, and you may obtain copies of those documents as described below under “Where You Can Find More Information.”

You should rely only on the information contained or incorporated or deemed incorporated by reference in this prospectus, in any applicable prospectus supplement or in any free writing prospectus filed by us with the SEC. We have not authorized anyone to provide any information other than that contained in this prospectus or in any prospectus supplement or free writing prospectus prepared by or on behalf of us or to which we may have referred you. We do not take any responsibility for, and can provide no assurance as to the reliability of, any other information that others may give you. We have not authorized any other person to provide you with different or additional information, and we are not making an offer to sell securities in any jurisdiction where the offer or sale is not permitted. You should assume that the information appearing in this prospectus is accurate only as of the date hereof or, in the case of information incorporated or deemed incorporated by reference herein, as of the date thereof, or, in each case, as of any earlier date as of which such information is given, regardless of the time of delivery of the prospectus or any sale of securities. Our business, financial condition, results of operations and prospects may have changed since the date of such information.

We file annual, quarterly and current reports, proxy statements and other information with the SEC. Our SEC filings are available to the public from the SEC website at http://www.sec.gov.

The SEC allows us to incorporate by reference the information we file with them, which means that we can disclose important information to you by referring you to those documents. The information incorporated by reference is considered to be a part of this prospectus, and later information that we file with the SEC will automatically update and, to the extent inconsistent, supersede this information. SEC rules and regulations also permit us to “furnish” rather than “file” certain reports and information with the SEC. Any such reports or information which we “furnish” or have “furnished” shall not be deemed to be incorporated by reference into or otherwise become a part of this prospectus, regardless of when furnished to the SEC. We incorporate by reference the following documents listed below and any future filings made with the SEC under Section 13(a), 13(c), 14 or 15(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) (other than, in each case, information deemed to have been furnished and not filed in accordance with SEC rules), on or after the date of this prospectus until we have terminated the offerings of all of the securities to which this prospectus relates:

The following table sets forth the various expenses to be incurred in connection with the sale and distribution of the securities being registered hereby, all of which will be borne by PENN Entertainment, Inc. (the “Company”).

Under Sections 1741 and 1742 of the Pennsylvania Business Corporation Law, as amended (“PBCL”), a business corporation has the power to indemnify any person who was or is a party, or is threatened to be made a party, to any threatened, pending or completed action or proceeding, whether civil, criminal, administrative or investigative, by reason of the fact that such person is or was a representative of the corporation, or is or was serving at the request of the corporation as a director or officer of another corporation or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action or proceeding, if such person acted in good faith in a manner he or she reasonably believed to be in, or not opposed to, the best interests of the corporation, and, with respect to any criminal proceeding, had no reasonable cause to believe his or her conduct was unlawful. In the case of a threatened, pending or completed action or proceeding by or in the right of the corporation, such indemnification only covers expenses (including attorneys’ fees) actually and reasonably incurred in defense and settlement of such action and excludes judgments and amounts paid in settlement with respect to such action or proceeding, and no indemnification can be made for expenses if such person has been adjudged to be liable to the corporation unless, and only to the extent that, a court determines upon application that, despite the adjudication of liability but in view of all the circumstances, such person is fairly and reasonably entitled to indemnity for the expenses that the court deems proper.

In addition, Section 1744 of the PBCL provides that, unless ordered by a court, any indemnification referred to above shall be made by the corporation only as authorized in the specific case upon a determination that indemnification of the representative is proper in the circumstances because the indemnitee has met the applicable standard of conduct. Such determination shall be made:

Notwithstanding the above, Section 1743 of the PBCL provides that, to the extent that a director or officer of a business corporation has been successful on the merits or otherwise in defense of a proceeding referred to above, or in

defense of any claim, issue or matter therein, such person shall be indemnified against expenses (including attorneys’ fees) actually and reasonably incurred by such person in connection therewith.

Further, Section 1745 of the PBCL provides that expenses (including attorneys’ fees) incurred by an officer or director of a business corporation in defending any such proceeding may be paid by the corporation in advance of the final disposition of the proceeding upon receipt of an undertaking to repay the amount advanced if it is ultimately determined that the indemnitee is not entitled to be indemnified by the corporation.

Also, Section 1746 of the PBCL provides that the indemnification and advancement of expenses provided by, or granted pursuant to, the foregoing provisions shall not be deemed exclusive of any other rights to which a person seeking indemnification or advancement of expenses may be entitled under any bylaw, agreement, vote of shareholders or disinterested directors or otherwise, and that indemnification may be granted under any bylaw, agreement, vote of shareholders or directors or otherwise for any action taken or any failure to take any action whether or not the corporation would have the power to indemnify the person under any other provision of law and whether or not the indemnified liability arises or arose from any action by or in the right of the corporation; provided, however, that no indemnification may be made in any case where the act or failure to act giving rise to the claim for indemnification is determined by a court to have constituted willful misconduct or recklessness.

Section 1747 of the PBCL permits a Pennsylvania business corporation to purchase and maintain insurance on behalf of any person who is or was a director or officer of the corporation, or is or was serving at the request of the corporation as a director or officer of another corporation or other enterprise, against any liability asserted against such person and incurred by such individual in any such capacity, or arising out of his or her status as such, whether or not the corporation or other enterprise would have the power to indemnify the person against such liability under the provisions described above.

Section 8.01 of the Sixth Amended and Restated Bylaws of the Company (the “PENN Bylaws”) provide for indemnification, to the fullest extent permitted by Pennsylvania law, for directors, officers and certain employees against all liability, loss and expense (including attorneys’ fees, judgments, fines and amounts paid in settlement) actually and reasonably incurred by such person by reason of the fact that such person is or was a director or officer of PENN, or is or was serving at the request of PENN as a director, officer, employee, agent, fiduciary or trustee of another corporation or of a partnership, joint venture, trust, employee benefit plan or other enterprise or entity. The PENN Bylaws also require the advancement of expenses incurred by an indemnified representation in connection with an indemnified matter.

Section 8.07 of the PENN Bylaws provides that, among other things, it may purchase and maintain insurance or enter into indemnifications to secure its indemnification provisions.

PENN maintains directors’ and officers’ liability insurance covering its directors and officers with respect to liabilities, which they may incur in connection with their serving in such capacity. Under this insurance, PENN may receive reimbursement for amounts as to which the directors and officers are indemnified by PENN under the bylaw indemnification provisions described above. Such insurance also provides certain additional coverage for the directors and officers against certain liabilities even though such liabilities may not be covered by the bylaw indemnification provisions described above.

As permitted by Section 1713(a) of the PBCL, Section 4.14 of the PENN Bylaws provide that no director shall be personally liable, as such, for monetary damages for any action taken, or failure to take any action, unless (i) the director has breached or failed to perform the duties of his or her office under the articles, bylaws or the PBCL; and (ii) the breach or failure to perform constitutes self-dealing, willful misconduct or recklessness. Section 1713(b) of the PBCL states that this exculpation from liability does not apply to the responsibility or liability of a director pursuant to any criminal statute or the liability of a director for the payment of taxes pursuant to federal, state or local law. It is uncertain whether this provision will control with respect to liabilities imposed upon directors by federal law, including federal securities laws. Section 1715(d) of the PBCL creates a presumption, subject to exceptions, that a director acted in the best interests of the corporation. Section 1712 of the PBCL, in defining the standard of care a director owes to the corporation, provides that a director stands in a fiduciary relation to the corporation and must perform his or her duties as a director or as a member of any committee of the board of directors in good faith, in a manner he or she reasonably believes to be in the best interests of the corporation and with such care, including the skill and diligence, that a person of ordinary prudence would use under similar circumstances and reasonable inquiry into those issues.

The foregoing summaries are subject to the complete text of the PBCL and the PENN Bylaws and are qualified in their entirety by reference thereto.
