Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions (see General Instruction A.2. below):

On August 2, 2016, LinnCo, LLC (“LinnCo”) issued a press release announcing the final results of, and expiration of the subsequent offering period relating to, its previously announced offer to exchange each outstanding unit of LINN Energy, LLC (the “Company” or “LINN Energy”) for one LinnCo share (the “Exchange Offer”) upon the terms and conditions of the Prospectus/Offer to Exchange dated April 26, 2016 (as amended, the “Prospectus”), and the accompanying Amended and Restated Letter of Transmittal (the “Letter of Transmittal”). A copy of the press release is attached hereto as Exhibit 99.1.

The subsequent offering period for the Exchange Offer expired at 12:00 midnight (New York City time) on Monday, August 1, 2016. American Stock Transfer & Trust Company, the exchange agent for the Exchange Offer, has advised LinnCo that a total of 19,954,774 LINN Energy units were validly tendered during the subsequent offering period and an aggregate of 123,909,317 LINN Energy units (including LINN Energy units accepted for exchange during the initial offering period), representing approximately 35% of the Company’s issued and outstanding units, were validly tendered and not validly withdrawn pursuant to the Exchange Offer and have been accepted by LinnCo for exchange. LinnCo has promptly issued new LinnCo shares for all such tendered LINN Energy units in accordance with the terms of the Exchange Offer. LinnCo now owns approximately 71% of the Company’s issued and outstanding units.

As previously reported by the Company in a Current Report on Form 8-K filed by the Company with the Securities and Exchange Commission (the “SEC”) on May 11, 2016, the Company, LinnCo, certain of the Company’s direct and indirect subsidiaries, and Berry Petroleum Company, LLC (collectively, the “Debtors”), filed voluntary petitions (the “Bankruptcy Petitions”) for reorganization under Chapter 11 of the United States Bankruptcy Code (the “Bankruptcy Code”) in the United States Bankruptcy Court for the Southern District of Texas (the “Court”). On May 16, 2016, the Court approved and entered an order authorizing LinnCo to continue the Exchange Offer throughout the Debtors’ Chapter 11 proceedings and to take any and all actions necessary to effectuate the Exchange Offer in accordance with its terms. Any party not represented by counsel who would like to receive electronic notifications of filings with the Court may complete the appropriate Court-approved form, which can be obtained at the following address: http://www.txs.uscourts.gov/sites/txs/files/CRECFform.pdf. Copies of this form are also available on the website of the Company’s claims, noticing, and solicitation agent, Prime Clerk LLC, at https://cases.primeclerk.com/linn.

The purpose of the Exchange Offer was to permit holders of LINN Energy units to maintain their economic interest in the Company through LinnCo, an entity that is taxed as a corporation rather than a partnership, which may allow LINN Energy unitholders to avoid future allocations of taxable income and loss, including cancellation of debt income (“CODI”), that could result from future debt restructurings or other strategic transactions by the Company. In general, CODI will be allocated to persons who are deemed to hold the LINN Energy units when the events giving rise to such CODI occur. The filing of the Bankruptcy Petitions under Chapter 11 of the Bankruptcy Code did not itself cause the Company to recognize CODI; however, it is likely that the final resolution of a bankruptcy plan would cause the Company to recognize an amount of CODI, which may be substantial.

Important Additional Information Filed with the SEC

This information filed pursuant to Item 7.01 of this Current Report on Form 8-K (including the exhibit) is for informational purposes only and does not constitute an offer to sell, a solicitation to buy or offer to purchase or sell LINN Energy units or any other securities. The Exchange Offer was made only pursuant to the Prospectus and the Letter of Transmittal and only in such jurisdictions as is permitted under applicable law. LinnCo is filing today with the SEC an amendment to its Tender Offer Statement on Schedule TO related to the Exchange Offer, and thereafter the Company will file an amendment to its Solicitation/Recommendation Statement on Schedule 14D-9 with respect to the Exchange Offer. LinnCo and the Company may also file other documents with the SEC regarding the Exchange Offer. This document is not a substitute for Schedule TO, Schedule 14D-9 or any other document that LinnCo or the Company may file with the SEC in connection with the Exchange Offer.
