Item 7.01. Regulation FD Disclosure.

As previously announced, on November 10, 2014, Dendreon Corporation (the “Company”) and its wholly owned subsidiaries, Dendreon Holdings, LLC, Dendreon Distribution, LLC and Dendreon Manufacturing, LLC (collectively, together with the Company, the “Debtors”) filed voluntary petitions for relief (the “Chapter 11 Cases”) under Chapter 11 of Title 11 of the United States Code (the “Bankruptcy Code”) in the United States Bankruptcy Court for the District of Delaware (the “Bankruptcy Court”).

As previously disclosed, on March 10, 2015, the Debtors filed with the Bankruptcy Court a proposed plan of liquidation for the resolution of the outstanding claims against and interests in the Debtors pursuant to section 1121(a) of the Bankruptcy Code. The Debtors filed a modified version of the proposed plan of liquidation with the Bankruptcy Court on April 14, 2015. On May 14, 2015, the Debtors filed a further modified version of the proposed plan of liquidation (as subsequently amended, modified or supplemented, the “Plan”) with the Bankruptcy Court. The Plan was confirmed by the Bankruptcy Court on June 2, 2015.

Under the Plan, in the event that holders of claims on account of the Company’s 2.875% Convertible Senior Notes due 2016 (the “2016 Notes”) and holders of general unsecured claims receive a 100% recovery (including all accrued but unpaid postpetition interest) pursuant to the Plan, and all wind-down costs of the Chapter 11 Cases are satisfied, then the Company’s equity securityholders shall be entitled to any residual recovery pursuant to certain procedures set forth in the Plan, and holders of allowed subordinated claims shall be entitled to a distribution pari passu with any such distribution to the Company’s equity securityholders. The Debtors do not anticipate that there will be any residual recovery for the Company’s equity securityholders.

The Company intends to file a copy of the order confirming the Plan on Form 8-K following entry of such order by the Bankruptcy Court.

Cautionary Statements Regarding the Chapter 11 Cases

The Company’s securityholders are cautioned that trading in the Company’s securities during the pendency of the Chapter 11 Cases will be highly speculative and will pose substantial risks. Trading prices for the Company’s securities may bear little or no relationship to the actual recovery, if any, by holders thereof in the Company’s Chapter 11 Cases. Accordingly, the Company urges extreme caution with respect to existing and future investments in its securities. The Bankruptcy Court has entered an order that places limitations on trading in the Company’s common stock, including options and certain other rights to acquire common stock, and certain instruments convertible into common stock, during the pendency of the bankruptcy proceedings.

Although the Plan provides for a potential residual recovery for the Company’s equity secuityholders, this would only occur after holders of claims on account of the 2016 Notes and holders of general unsecured claims receive a 100% recovery (including all accrued but unpaid postpetition interest) pursuant to the Plan, and all wind-down costs of the Chapter 11 Cases are satisfied. The Debtors do not anticipate that there will be any residual recovery for the Company’s equity securityholders. Instead, the Debtors expect that the Company’s equity securityholders will receive no distribution on account of their existing interests, which will be cancelled pursuant to the Plan.

Cautionary Statement Regarding Forward-Looking Statements

Certain information in this Current Report on Form 8-K (this “Current Report”) may constitute forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. All statements contained in this Current Report that are not statements of historical fact, including estimates, projections, future trends and the outcome of events that have not yet occurred referenced in this Current Report should be considered forward-looking statements. Words such as “anticipate,” “estimate,” “expect,” “project,” “intend,” “plan,” “believe,” “may,” “predict,” “will,” “would,” “could,” “should,” “target” and similar expressions are often used to identify forward-looking statements. Actual results or events could differ materially from those indicated in forward-looking statements as a result of risks and uncertainties, including, among others, the potential adverse impact of the Chapter 11 Cases on the Company’s liquidity or results of operations, changes in the Company’s ability to meet financial obligations during the Chapter 11 process or to

maintain contracts that are critical to the Company’s wind-down of its affairs, the outcome or timing of the Chapter 11 process, the effect of the Chapter 11 Cases or the recently completed asset sale transaction with Valeant Pharmaceuticals International, Inc. and Drone Acquisition Sub Inc. on the Company’s relationships with third parties, regulatory authorities and employees in connection with the Company’s wind-down of its affairs, proceedings that may be brought by third parties in connection with the Chapter 11 process, the ability of the Company to fund the wind-down of its affairs and the timing or amount of any distributions to the Company’s stakeholders. For a discussion of some of the additional risks and important factors that the Company believes could cause actual results or events to differ from the forward-looking statements that it makes, see the sections entitled “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in the Company’s Quarterly Report on Form 10-Q for the quarter ended September 30, 2014. In addition, new risks and uncertainties emerge from time to time, and it is not possible for the Company to predict or assess the impact of every factor that may cause its actual results or events to differ from those contained in any forward-looking statements. Accordingly, you should not place undue reliance on any forward-looking statements contained in this Current Report. Any forward-looking statements speak only as of the date of this Current Report. The Company undertakes no obligation to publicly update forward-looking statements, whether as a result of new information, future events or otherwise.
