The Merger

The merger agreement provides that, upon the terms and subject to the conditions set forth in the merger agreement and in accordance with the applicable provisions of the General Corporation Law of the State of Delaware (the “DGCL”) and the Delaware Limited Liability Company Act (the “LLC Act”), LinnCo will acquire Berry and contribute Berry to LINN in a multi-step transaction:

We refer to the HoldCo Merger, the Conversion, the LinnCo Merger, the Contribution and the Issuance together as the “transactions.”

A copy of the merger agreement is attached as Annex A to this joint proxy statement/prospectus and is incorporated by reference herein. Please carefully read the merger agreement as it is the legal document that governs the merger.

Berry Stockholders Will Receive LinnCo Common Shares in the Merger

If the merger is completed, Berry stockholders will receive 1.25 LinnCo common shares for each share of Berry common stock that they own. The exchange ratio is fixed and will not be adjusted to reflect changes in the price of Berry common stock or LinnCo common shares prior to the closing of the merger.

Based on the closing price of LinnCo common shares on the NASDAQ of $36.99 on February 20, 2013, the last trading day before public announcement of the proposed transactions, the exchange ratio represented approximately $46.2375 in LinnCo common shares for each share of Berry common stock. Based on the closing price of LinnCo common shares on the NASDAQ of $                              on                     , 2013, the latest practicable date before the date of this joint proxy statement/prospectus, the exchange ratio represented approximately $         in LinnCo common shares for each share of Berry common stock. The value of the merger consideration will fluctuate with changes in the market price of LinnCo common shares. We urge you to obtain current market quotations of LinnCo common shares and Berry common stock. See “Comparative Market Prices and Dividends” beginning on page 198.

Risk Factors

Before voting at the Berry special meeting, the LinnCo annual meeting or the LINN annual meeting, you should carefully consider all of the information contained in or incorporated by reference into this joint proxy statement/prospectus, as well as the specific factors under the heading “Risk Factors” beginning on page 34.

Holders of Berry Equity-Based Awards

Options. Each option to purchase shares of Berry common stock will be converted into an option to purchase, generally on the same terms and conditions as were applicable to such option immediately prior to the effective time of the merger, (i) a number of LINN units (rounded down to the nearest whole unit) equal to the product determined by multiplying the number of shares of Berry common stock subject to such option by the exchange ratio and by the LinnCo/LINN exchange ratio (as defined below), (ii) at an exercise price per LINN unit (rounded up to the nearest whole cent) equal to the quotient determined by dividing the per share exercise price for the shares of Berry common stock subject to the option by the product determined by multiplying the exchange ratio and the LinnCo/LINN exchange ratio. The LinnCo/LINN exchange ratio is the average of the closing prices of one LinnCo common share on the NASDAQ on the last five full trading days prior to the closing date of the merger divided by the average of the closing prices of one LINN unit on the NASDAQ on the last five full trading days prior to the closing date of the merger.

Restricted Stock Units. Each unvested Berry restricted stock unit (“RSU”) (excluding any Berry RSU held by a current or former non-employee director of Berry and any performance-based Berry RSU) will be converted as of the effective time of the merger into a restricted unit award in respect of the number of LINN units (rounded to the nearest whole unit) equal to the product determined by multiplying the number of shares of Berry common stock subject to the Berry RSU immediately prior to the effective time of the merger by the exchange ratio and by the LinnCo/LINN exchange ratio, and will be subject generally to the same terms and conditions as were applicable to the related Berry RSU immediately prior to the effective time of the merger.

Each Berry RSU that is vested as of the effective time of the merger, that is held by a current or former non-employee director or that is subject to performance-based vesting criteria will be converted as of the effective time of the merger into a number of LinnCo common shares equal to the product determined by multiplying the number of shares of Berry common stock subject to the Berry RSU immediately prior to the effective time of the merger by the exchange ratio. Each performance-based Berry RSU that is outstanding immediately prior to the effective time of the merger will be deemed to have been earned at the target level as specified in the applicable award agreement.

Material U.S. Federal Income Tax Consequences of the Merger

It is a condition to Berry’s obligation to complete the merger that Berry receive a written opinion from Wachtell, Lipton, Rosen & Katz, special counsel to Berry, to the effect that each of (a) the HoldCo Merger and the Conversion, taken together, and (b) the LinnCo Merger will qualify as a “reorganization” within the meaning of Section 368(a) of the Code. It is a condition to LinnCo’s obligation to complete the merger that LinnCo receive a written opinion from Latham & Watkins LLP, special counsel to LinnCo, to the effect that the LinnCo Merger will qualify as a “reorganization” within the meaning of Section 368(a) of the Code. In addition, in connection with the filing of the registration statement of which this document is a part, each of Wachtell, Lipton, Rosen & Katz and Latham & Watkins LLP has delivered an opnion to Berry and LinnCo, respectively, to the same effect.

Accordingly, and on the basis of the opinions delivered in connection herewith, U.S. holders of Berry common stock generally will not recognize gain or loss, for U.S. federal income tax purposes, upon their receipt of LinnCo common shares in exchange for Berry common stock pursuant to the merger, except with respect to cash received in lieu of fractional LinnCo common shares.

Holders of Berry common stock should consult their tax advisors to determine the tax consequences to them (including the application and effect of any state, local or non-U.S. income and other tax laws) of the merger.

Citigroup’s opinion is not intended to be, and does not constitute, a recommendation to any LinnCo shareholder as to how such shareholder should vote or act on any matters relating to the proposed transactions or otherwise. Under the terms of Citigroup’s engagement, LinnCo has agreed to pay Citigroup a fee for its financial advisory services in connection with the transactions, a significant portion of which is contingent upon completion of the transactions.

Board of Directors and Management of LinnCo Following Completion of the Merger

Upon completion of the merger, the current directors and officers of LinnCo and LINN are expected to continue in their current positions. In addition, one member of the Berry board of directors will be appointed to serve either on the LinnCo board of directors or the LINN board of directors. Information about the current LinnCo directors and executive officers can be found in this joint proxy statement/prospectus. See “Additional Information About LinnCo, LLC—Management” beginning on page 204.

Share Ownership of Directors and Executive Officers of Berry

At the close of business on                     , 2013, the directors and executive officers of Berry and their affiliates held and were entitled to vote              shares of Berry common stock, collectively representing approximately     % of the shares of Berry common stock outstanding and entitled to vote on that date. It is Berry’s understanding as of the date of this document that the directors and executive officers of Berry intend to vote “FOR” the Berry Merger Proposal, “FOR” the Berry Advisory Compensation Proposal and “FOR” the Berry Adjournment Proposal.

Share and Unit Ownership of Directors and Executive Officers of LinnCo and LINN

At the close of business on                     , 2013, the directors and executive officers of LinnCo, LINN and their affiliates did not hold any LinnCo common shares and held and were entitled to vote      LINN units, collectively representing approximately     % of the LINN units outstanding and entitled to vote on that date.

Interests of Berry’s Directors and Executive Officers in the Merger

Certain members of the board of directors and executive officers of Berry may be deemed to have interests in the merger that are in addition to, or different from, the interests of other Berry stockholders. The Berry board of directors was aware of these interests and considered them, among other matters, in approving the merger and the merger agreement and in making the recommendations that the Berry stockholders adopt the merger agreement and approve the merger and the other transactions contemplated by the merger agreement. These interests include:

Appraisal Rights

Under Section 262 of the DGCL, holders of Berry common stock may have the right to obtain an appraisal of the fair value of their shares of Berry common stock in connection with the merger. To properly demand appraisal rights, a Berry stockholder must not vote in favor of the proposal to adopt the merger agreement and the transactions contemplated by the merger agreement, must continue to hold such stockholder’s shares of common stock through the effective date of the merger and must strictly comply with all of the other procedures required to demand and perfect appraisal rights under Section 262 of the DGCL, including submitting a written demand for appraisal to Berry prior to the Berry special meeting. Failure by a Berry stockholder to strictly comply with the provisions of Section 262 of the DGCL may result in the loss or waiver of that stockholder’s appraisal rights. Because of the complexity of Section 262 of the DGCL relating to appraisal rights, if any Berry stockholder is considering exercising appraisal rights, Berry and LinnCo encourage such Berry stockholder to seek the advice of legal counsel. A summary of the requirements under Delaware law to exercise appraisal rights is included in this document under “The Merger—Appraisal Rights” beginning on page 137 and the text of Section 262 of the DGCL as in effect with respect to this transaction is included as Annex I to this document.

Listing of LinnCo Common Shares; Delisting and Deregistration of Shares of Berry Common Stock

Approval of the listing on the NASDAQ of the newly issued LinnCo common shares to be issued to Berry stockholders pursuant to the merger agreement, subject to official notice of issuance, is a condition to each party’s obligation to complete the merger. LinnCo has agreed to cause the LinnCo common shares to be issued to Berry stockholders pursuant to the merger agreement to be approved for listing on the NASDAQ prior to the effective time of the merger, subject to official notice of issuance. If the merger is completed, shares of Berry common stock will be delisted from the NYSE and deregistered under the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

Conditions That Must Be Satisfied or Waived for the Merger to Occur

Currently, we expect to complete the merger in the third quarter of 2013. As more fully described in this joint proxy statement/prospectus and in the merger agreement, the completion of the merger depends on a number of conditions being satisfied or, where legally permissible, waived. These conditions include, among others, approval of the Berry Merger Proposal by the Berry stockholders, approval of the LinnCo Share Issuance Proposal and the LinnCo LLC Agreement Amendment Proposal by the LinnCo shareholders, approval of the LINN Unit Issuance Proposal by the LINN unitholders, the absence of any injunction or law that prohibits closing, the effectiveness of the registration statement on Form S-4 of which this joint proxy statement/prospectus is a part, the absence of any material adverse effect experienced by any party to the merger agreement and the receipt of legal opinions by each company regarding certain tax matters. We cannot be certain when, or if, the conditions to the merger will be satisfied or waived, or that the merger will be completed.

Termination of the Merger Agreement

The merger agreement can be terminated at any time prior to completion by:

If the merger agreement is terminated, there will be no liability on the part of Berry, LinnCo or LINN, except that (1) Berry, LinnCo and LINN will remain liable for any fraud or willful or intentional breach of any covenant or agreement in the merger agreement occurring prior to termination or as provided for in the Confidentiality Agreement between Berry and LINN and (2) each party may be required to pay the other party a termination fee and/or reimburse certain expenses of the other party as described below under “—Termination Fee.”

Derivative Transactions upon Termination

Berry implemented certain derivative transactions with respect to its production following the execution of the merger agreement. The merger agreement provides that, in general, LinnCo and LINN will bear all of the benefits and burdens of these derivative transactions if the merger agreement is terminated. However, if the merger agreement is terminated because (1) the Berry board of directors changes its recommendation for the merger or (2) Berry terminates the merger agreement to accept a “company superior proposal,” then Berry and LinnCo will each bear half of the burdens and receive half of the benefits associated with the derivative transactions. In addition, if one party willfully breaches its obligations under the merger agreement, then the breaching party will bear all of the losses associated with the derivative transactions and, if the derivative transactions resulted in a gain, then the non-breaching party will receive all of such gain. See “The Merger Agreement—Derivative Transactions upon Termination” beginning on page 165.

Termination Fee

Berry is obligated to pay LinnCo a termination fee or expense reimbursement in the following circumstances:

LinnCo is obligated to pay Berry a termination fee or expense reimbursement in the following circumstances:

Regulatory Approvals Required for the Merger

Berry, LinnCo and LINN have agreed to use their reasonable best efforts to obtain all regulatory approvals required to complete the transactions contemplated by the merger agreement. These approvals include clearance

under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (the “HSR Act”) and approval from the Federal Energy Regulatory Commission (“FERC”) and other regulatory authorities. Berry, LinnCo and LINN have completed, or will complete, the filing of applications and notifications to obtain the required regulatory approvals. On March 13, 2013, the Federal Trade Commission (“FTC”) granted early termination of the waiting period under the HSR Act with respect to the merger. On May 15, 2013, Berry received FERC approval of certain aspects of the merger. See “The Merger—Regulatory Approvals Required for the Merger” on page 141.

Although Berry, LinnCo and LINN do not know of any reason why they cannot obtain any remaining regulatory approvals in a timely manner, they cannot be certain when or if they will obtain them.

The Rights of the Berry Stockholders will be Governed by the LinnCo Certificate of Formation and Limited Liability Company Agreement after the Merger

The rights of the Berry stockholders will change as a result of the merger due to differences in Berry’s and LinnCo’s governing documents. After the merger, Berry stockholders’ rights will be governed by the governing documents of LinnCo (as amended pursuant to the LinnCo LLC Agreement Amendment Proposal). This document contains a description of stockholder rights under Berry’s governing documents and shareholder rights under LinnCo’s governing documents and describes the material differences between them.

Berry Special Meeting

The Berry special meeting will be held at                     , at                     , local time, on                     , 2013. At the Berry special meeting, Berry stockholders will be asked to consider and vote upon:

Each share of Berry Class A common stock is entitled to one vote and each share of Berry Class B common stock is entitled to 95% of one vote (we refer to shares of Berry Class A common stock and Berry Class B common stock together as the “Berry common stock”) on each proposal to be presented at the Berry special meeting.

Required Vote. Approval of the Berry Merger Proposal requires the affirmative vote of a majority of the votes entitled to be cast by all outstanding shares of Berry common stock, voting together as a single class, entitled to vote at the Berry special meeting. Each of the approval of the Berry Advisory Compensation Proposal and approval of the Berry Adjournment Proposal requires the affirmative vote of a majority of votes cast by the Berry common stockholders at the Berry special meeting. Approval of the Berry Merger Proposal is a condition to the completion of the transactions contemplated by the merger agreement.

As of the record date, directors and executive officers of Berry and its affiliates had the right to vote approximately              shares of Berry common stock, or     % of the outstanding Berry common stock entitled to be voted at the Berry special meeting.

LinnCo Annual Meeting

The LinnCo annual meeting will be held at                     , at                     , local time, on                     , 2013. At the LinnCo annual meeting, LinnCo shareholders will be asked to consider and vote upon:

Each LinnCo common share is entitled to one vote. As of the record date of May 13, 2013, there were approximately              LinnCo common shares entitled to vote at the LinnCo annual meeting. LINN owns the sole LinnCo share entitled to vote with respect to the election of members of the LinnCo board of directors and with respect to certain other matters; however, all LinnCo common shares outstanding on the record date for the LinnCo annual meeting are entitled to vote on all proposals to be presented at the LinnCo annual meeting.

Each change to the LinnCo LLC Agreement to be voted on in the LinnCo LLC Agreement Amendment Proposal was separately negotiated and bargained for by Berry, and the adoption of all such changes by the LinnCo shareholders is a condition to the merger. If approved by the LinnCo shareholders, the amendments to the LinnCo LLC agreement will apply not only to the transactions described in this joint proxy statement/prospectus, but also to any other offering and sale of LinnCo common shares in the future. Accordingly, while these amendments are required to permit the transactions described in this joint proxy statement/prospectus, LinnCo

may rely on these amendments to engage in acquisition transactions in the future on which you may not be entitled to vote. See “The LinnCo Annual Meeting—Proposal No. 2—LinnCo LLC Agreement Amendment Proposal.”

Pursuant to the LinnCo limited liability company agreement, the LinnCo shareholders are entitled to vote on the LINN Pass-Through Proposals to determine how LinnCo will vote its LINN units on such proposals. LinnCo, as a LINN unitholder, will use its commercially reasonable efforts to vote (or refrain from voting) the LINN units it holds at the LINN annual meeting in the same manner as the LinnCo common shareholders entitled to vote as of the record date voted thereon (or refrained from voting). Please see “The LINN Annual Meeting” beginning on page 70 for the vote requirements for the LINN Pass-Through Proposals. The approval of the LINN Unit Issuance Proposal is a condition to the completion of the transactions contemplated by the merger agreement.

The affirmative vote of a majority of votes cast by holders of LINN units entitled to vote at a meeting at which a quorum is present is required to approve the LINN Unit Issuance Proposal and the LTIP Amendment Proposal. Unitholder ratification of the selection of KPMG LLP as independent public accountant for LINN for 2013 is not required under LINN’s limited liability company agreement; however, when the matter is submitted for unitholder approval, the affirmative vote of a majority of votes cast by holders of LINN units entitled to vote at a meeting at which a quorum is present is required. The affirmative vote of a majority of votes cast by holders of LINN units entitled to vote at a meeting, whether or not a quorum exists, is required to approve the LINN Adjournment Proposal. The approval of the LINN Unit Issuance Proposal is a condition to the completion of the transactions contemplated by the merger agreement.

Litigation Relating to the Merger

On March 21, 2013, a purported stockholder class action captioned Nancy P. Assad Trust v. Berry Petroleum Co., et al. was filed in the District Court for the City and County of Denver, Colorado, No. 13-CV-31365. The action names as defendants Berry, the members of its board of directors, HoldCo, Bacchus Merger Sub, LinnCo, LINN and LinnCo Merger Sub. On April 5, 2013, an amended complaint was filed, which alleges that the individual defendants breached their fiduciary duties in connection with the transactions by engaging in an unfair sales process that resulted in an unfair price for Berry, by failing to disclose all material information regarding the transactions, and that the entity defendants aided and abetted those breaches of fiduciary duty. The amended complaint seeks a declaration that the transactions are unlawful and unenforceable, an order directing the individual defendants to comply with their fiduciary duties, an injunction against consummation of the transactions, or, in the event they are completed, rescission of the transactions, an award of fees and costs, including attorneys’ and experts’ fees and expenses, and other relief. On May 21, 2013, the Colorado District Court stayed and administratively closed the Nancy P. Assad Trust action in favor of the Hall action described below that is pending in the Delaware Court of Chancery.
