EXPLANATORY NOTE

The Registrant hereby amends its registration statement on Form S-4 (File No. 333-228088) filed with the Commission on October 31, 2018, as amended by Amendment No. 1 filed with the Commission on November 30, 2018, Amendment No. 2 filed with Commission on December 14, 2018 and Amendment No. 3 filed with the Commission on December 19, 2018 (as amended, the “Form S-4”), which the Commission declared effective on December 20, 2018, by filing this Post-Effective Amendment No. 1 on Form S-8 (this “Post-Effective Amendment” and together with the Form S-4, this “Registration Statement”).

The Registrant filed the Form S-4 in connection with the transactions contemplated by the Agreement and Plan of Merger and Reorganization by and among Pandora Media, Inc., a Delaware corporation (“Pandora”), Billboard Holding Company Inc., a Delaware corporation and a wholly-owned subsidiary of Pandora (“New Holding Company”), Billboard Acquisition Sub, Inc., a Delaware corporation and wholly-owned subsidiary of New Holding Company, the Registrant, White Oaks Acquisition Corp, a Delaware corporation and a wholly-owned subsidiary of the Registrant, and Sirius XM Radio Inc., a Delaware corporation and wholly-owned subsidiary of the Registrant, dated September 23, 2018 (as may be amended from time to time, the “Merger Agreement”). On February 1, 2019, through a series of transactions set forth in the Merger Agreement, Pandora became an indirect wholly owned subsidiary of the Registrant (the “Merger”).

As a result of the Merger, each option, whether vested or unvested, to acquire shares of Pandora common stock, par value $0.0001 per share (“Pandora common stock”), and each unvested restricted stock unit, in each case, granted under Pandora’s (i) 2014 Stock Incentive Plan of AdsWizz Inc., (ii) Pandora Media, Inc. 2011 Equity Incentive Plan, (iii) Pandora Media, Inc. 2004 Stock Plan and (iv) TheSavageBeast.com, Inc. 2000 Stock Incentive Plan (collectively, the “Pandora Equity Plans”) converted into options and restricted stock unit awards, as applicable, covering shares of Sirius XM common stock (the “Sirius XM Awards”), with appropriate adjustments to reflect the application of the Exchange Ratio (as defined in the Merger Agreement).

In accordance with the terms of the Sirius XM Holdings Inc. 2015 Long-Term Stock Incentive Plan (the “Sirius XM 2015 Plan”), as a result of the Merger, all shares available under the Pandora Equity Plans, which were previously approved by stockholders and not adopted in contemplation of the Merger, will become additional shares available for grant pursuant to the terms of Sirius XM 2015 Plan (as adjusted, to the extent appropriate, to reflect the application of the Exchange Ratio). Subject to certain limitations set forth in the Sirius XM 2015 Plan, such shares may be used for awards made after the Merger under the Sirius XM 2015 Plan.

The Registrant hereby amends the Form S-4 by filing this Post-Effective Amendment relating to 55,103,248 shares of Sirius XM common stock issuable upon the exercise or settlement, as applicable, of the Sirius XM Awards under the Pandora Equity Plans. All such shares were previously registered on the Form S-4 but will be subject to issuance pursuant to this Post-Effective Amendment.

The information specified in Item 1 and Item 2 of Part I of Form S-8 is omitted from this Registration Statement in accordance with the provisions of Rule 428 under the Securities Act.

The document(s) containing the information specified in Part I will be sent or given to employees as specified by Rule 428(b)(1) of the Securities Act.

PART II
INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

Item 3.  Incorporation of Documents by Reference.

The following documents, which have been filed by the Registrant with the Commission, are incorporated herein by reference:

All other reports and other documents subsequently filed by the Registrant pursuant to Sections 13(a), 13(c), 14 or 15(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), prior to the filing of a post-effective amendment which indicates that all securities offered hereby have been sold or which deregisters all securities then remaining unsold (other than information deemed to have been “furnished” rather than “filed” in accordance with the SEC’s rules), shall be deemed to be incorporated by reference into this Registration Statement and to be a part of this Registration Statement from the date of the filing of such reports and documents.

For the purposes of this Registration Statement, any statement contained in a document incorporated or deemed to be incorporated by reference herein shall be deemed to be modified or superseded to the extent that a statement contained herein or in any other subsequently filed document that also is or is deemed to be incorporated by reference herein modifies or supersedes such statement. Any such statement so modified or superseded shall not be deemed, except as so modified or superseded, to constitute a part of this Registration Statement.

Not applicable.

Not applicable.

Under Section 145 of the Delaware General Corporation Law (“DGCL”), a corporation may indemnify a director, officer, employee or agent of the corporation (or a person who is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise) against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation and, with respect to any criminal action or proceeding, if he had no reasonable cause to believe such person’s conduct was unlawful. In the case of an action brought by or in the right of a corporation, the corporation may indemnify a director, officer, employee or agent of the corporation (or a person who is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise) against expenses (including attorneys’ fees) actually and reasonably incurred by such person if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the corporation, except that no indemnification may be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent a court finds that, in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnification for such expenses as the court shall deem proper. The indemnification provisions of the DGCL require indemnification of a director or officer who has been successful on the merits in defense of any action, suit or proceeding that he was a party to by virtue of the fact that he is or was a director or officer of the corporation.

Section 145 of the DGCL further authorizes a corporation to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against any liability asserted against the person, and incurred by the person in any such capacity, or arising out of his or her status as such, whether or not the corporation would have the power to indemnify such person under Section 145 of the DGCL.

Section 102(b)(7) of the DGCL enables a Delaware corporation to provide in its certificate of incorporation for the elimination or limitation of the personal liability of a director to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director. However, no provision can eliminate or limit a director’s liability:

Article eleventh of the Registrant’s charter provides that no the Registrant director shall be personally liable to the Registrant or its stockholders for monetary damages for breach of fiduciary duty by that director as a director. However, this limitation does not eliminate or limit the liability of a director to the extent provided by applicable law (i) for any breach of the director’s duty of loyalty to the Registrant or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the DGCL, or (iv) for any transaction from which the director derived an improper personal benefit. If the DGCL is amended after November 14, 2013, the effective date of this article eleventh, to authorize corporate action further eliminating or limiting the personal liability of directors, then the liability of a director of the Registrant shall be eliminated or limited to the fullest extent permitted by the DGCL, as so amended.

Article eleventh of the Registrant’s charter also provides that the Registrant indemnifies, to the fullest extent permitted by law, any person (or the estate of any person) who was or is a party to, or is threatened to be made a party to, any threatened, pending or complete action, suit or proceeding, whether or not by or in the right of the Registrant, and whether civil, criminal, administrative, investigative or otherwise, by reason of the fact that such person is or was a director, officer or employee of the Registrant, or is or was serving at the request of the Registrant as a director, officer or employee of another corporation or organization. The Registrant may, to the full extent permitted by law, purchase and maintain insurance on behalf of any such person against any liability which may be asserted against him or her. To the full extent permitted by law, the indemnification includes expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement, and any such expenses may be paid by the Registrant in advance of the final disposition of such action, suit or proceeding. The indemnification does not limit the right of the Registrant to indemnify any other person for any such expenses to the full extent permitted by law, nor is it exclusive of any other rights to which any person seeking indemnification from the Registrant may be entitled under any agreement, vote of stockholders or disinterested directors or otherwise, both as to action in his or her official capacity and as to action in another capacity while holding such office.

Any repeal or modification of the foregoing paragraphs by the stockholders of the Registrant shall not adversely affect any right or protection of a director, officer or employee of the Registrant existing at the time of such repeal or modification.

The foregoing summaries are necessarily subject to the complete text of the statute, the registrant’s certificate of incorporation and bylaws, as amended to date, and the arrangements referred to above and are qualified in their entirety by reference thereto.

Not applicable.

The list of exhibits is set forth under “Exhibit Index” immediately preceding the signature pages hereto and is incorporated by reference herein.

(1)           To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement:

(i)           to include any prospectus required by Section 10(a)(3) of the Securities Act;

(ii)          to reflect in the prospectus any facts or events arising after the effective date of this Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate,

represent a fundamental change in the information set forth in this Registration Statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement; and

(iii)          to include any material information with respect to the plan of distribution not previously disclosed in this Registration Statement or any material change to such information in this Registration Statement;

provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) of this Item do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by this Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in this Registration Statement.

(2)           That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3)           To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(b)           The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in this Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c)           Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer, or controlling person of the Registrant in the successful defense of any action, suit, or proceeding) is asserted by such director, officer, or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
