Item 8.01. Other Events.

As previously disclosed, on August 14, 2018, Energen Corporation (“Energen”) entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Diamondback Energy, Inc. (“Diamondback”) and Sidewinder Merger Sub Inc., a wholly owned subsidiary of Diamondback (“Merger Sub”), providing for the merger of Merger Sub with and into Energen, with Energen surviving the merger as a wholly owned subsidiary of Diamondback (the “Merger”). On October 25, 2018, Energen and Diamondback filed with the Securities and Exchange Commission (the “SEC”) a definitive joint proxy statement, which also constitutes a prospectus of Diamondback, for the solicitation of proxies in connection with special meetings of Energen’s shareholders and Diamondback’s stockholders, each to be held on November 27, 2018, for purposes of voting, among other things, on matters necessary to complete the Merger (the “Proxy Statement”).

Supplemental Disclosures in Connection with Stockholder Litigation in Connection with the Merger

In connection with the Merger Agreement and the transactions contemplated thereby, a purported class action lawsuit (the plaintiff in such complaint, the “Gross Plaintiff”) and an individual lawsuit (the plaintiff in such complaint, the “Stein Plaintiff”) have been filed in the United States District Court for the Northern District of Alabama. Both complaints, captioned Gross v. Energen Corporation, et al., Case No. 2:18-cv-01711-RDP (filed October 17, 2018) and Stein v. Energen Corporation, et al., Case 2:18-cv-01746-JHE (filed October 22, 2018), assert claims against Energen and its directors. In general, the complaints allege that the defendants violated Sections 14(a) and 20(a) of the Exchange Act because the preliminary registration statement on Form S-4, as amended by Amendment No. 1 to the Form S-4, filed with the SEC (the “Registration Statement”) allegedly misrepresents or omits material information. The complaints seek, among other things, injunctive relief preventing the consummation of the Merger until additional disclosures are made, and damages.

On October 26, 2018, a purported shareholder derivative and class action complaint, captioned Rosenblatt v. Cohen, et al., Case No. 01-CV-2018-904321.00, was filed in the Circuit Court of Jefferson County, Alabama (the plaintiff in such complaint, the “Rosenblatt Plaintiff”) against Energen, Energen’s directors, Diamondback and Merger Sub in connection with the Merger. The complaint alleges state law breach of fiduciary duty claims against the Energen directors for, among other things, an allegedly inadequate price and alleged failure to disclose material information in the Registration Statement. The complaint also alleges that Diamondback aided and abetted the Energen directors’ alleged breaches of fiduciary duty. The complaint seeks, among other things, injunctive relief preventing the consummation of the Merger, and damages.

On November 15, 2018, Energen, Energen’s directors, Diamondback and Merger Sub reached an agreement to resolve the three lawsuits described above (the “Actions”). In connection with the resolution of the Actions and in order to alleviate the costs, risks and uncertainties inherent in litigation and provide additional information to investors, Energen and Diamondback have determined to voluntarily supplement the Proxy Statement with various disclosures. These disclosures are provided in this Current Report on Form 8-K. Nothing in this Current Report on Form 8-K will be deemed an admission of the legal necessity or materiality under applicable laws of any of the disclosures set forth herein. To the contrary, Energen, Energen’s directors, Diamondback and Merger Sub believe that all of the claims alleged in the Actions are without merit and specifically deny all allegations in the foregoing complaints, including, without limitation, that any additional disclosure was or is required. As part of this resolution, the Actions will be dismissed with prejudice as to the named plaintiffs and without prejudice as to all others. It is possible that additional, similar complaints may be filed. If this occurs, Energen and Diamondback do not intend to announce the filing of each additional, similar complaint or any amended complaint unless it contains materially new or different allegations.

SUPPLEMENT TO JOINT PROXY STATEMENT/PROSPECTUS

Diamondback and Energen are supplementing the Proxy Statement with certain additional information set forth below. These disclosures should be read in connection with the Proxy Statement, which should be read in its entirety. Defined terms used but not defined herein have the meanings set forth in the Proxy Statement. Without agreeing in any way that the disclosures below are material or otherwise required by law, Energen and Diamondback make the following amended and supplemental disclosures:

The disclosure on page 73 of the Proxy Statement in the section captioned “The Merger—Background of the Merger” is hereby supplemented by revising the first complete paragraph on the page in its entirety as follows:

Following the June 5, 2018 Energen board meeting, Energen’s representatives contacted a total of 16 potentially-interested companies identified by Energen’s management and financial advisors to determine their interest in a business combination transaction with Energen (or, in the case of three companies contacted on a “no-names” basis, to determine their interest in pursuing a large scale acquisition of an upstream exploration and production company). Five of the 16 were identified by management and Energen’s financial advisors as the most likely to be interested in and capable of engaging in a transaction with Energen that would be compelling to Energen’s shareholders (the “top-tier potential counterparties”). Of the companies contacted, three (all of which were among the top-tier potential counterparties) entered into non-disclosure agreements with Energen and were subsequently provided with certain non-public information, including Diamondback (which signed a non-disclosure agreement dated June 15, 2018), a second oil and gas company (which signed a non-disclosure agreement dated June 15, 2018, and is referred to as “Company A”) and a third oil and gas company (which signed a non-disclosure agreement dated June 26, 2018, and is referred to as “Company B”). The non-disclosure agreements with Diamondback and Company A contain standstill provisions, which, among other things, restrict Diamondback and Company A, respectively, from requesting that Energen amend or waive the standstill. Company B was requested to agree to similar provisions, but refused to agree to any standstill.

The disclosure on page 74 of the Proxy Statement in the section captioned “The Merger—Background of the Merger” is hereby supplemented by revising the sixth complete paragraph on the page in its entirety as follows:

On August 4, 2018, Energen and Diamondback executed an exclusivity agreement providing for a period of exclusive negotiations expiring on August 15, 2018, as well as an amended and restated non-disclosure agreement that provided for mutual disclosure of confidential information and included a mutual standstill provision, which, among other things, restricted Diamondback and Energen, respectively, from requesting that the other party amend or waive the standstill.

The disclosure beginning on page 99 of the Proxy Statement in the section captioned “The Merger—Opinion of J.P. Morgan, Energen’s Financial Advisor” is hereby supplemented by revising the subsection captioned “The Merger—Opinion of J.P. Morgan, Energen’s Financial Advisor—Transaction Multiples Analysis” in its entirety as follows:

Transaction Multiples Analysis

Using publicly available information, J.P. Morgan examined selected transactions in the Midland Basin and the Delaware Basin valued at greater than $250,000,000 as well as corporate transactions in the exploration and production sector generally where the parties had similar operations to Energen.

For each of the selected Midland Basin and Delaware Basin transactions for which the relevant information was publicly available, among other calculations, J.P. Morgan calculated the multiple of the production adjusted transaction value (calculated as the transaction value less the estimated run rate production value (assuming $35,000/Boepd)) to net acreage, both unadjusted and index-adjusted to reflect the change in the 36-month NYMEX strip from the transaction announcement date relative to the 36-month NYMEX strip on August 10, 2018 (which we refer to as the “Adjusted Transaction Value”). Specifically, J.P. Morgan reviewed the following Midland Basin and Delaware Basin transactions (buyer / seller) and observed the following multiples of production adjusted transaction value to index adjusted net acreage:


	Adjusted Transaction Value / Net Acreage ($/Acre)
Midland Basin
Diamondback Energy, Inc. / Ajax Resources, LLC		$31,753

For each of the selected corporate transactions for which the relevant information was publicly available, among other calculations, J.P. Morgan calculated the multiple of the transaction value to current year EBITDAX. Specifically, J.P. Morgan reviewed the following corporate transactions in the E&P sector (buyer / seller) and observed the following multiples of transaction value to current year EBITDAX:


		Transaction Value / CY EBITDAX
Concho Resources Inc. / RSP Permian, Inc.		10.0x
EQT Corporation / Rice Energy Inc.		9.4x
Noble Energy, Inc. / Clayton Williams Energy, Inc.		42.2x
Range Resources Corporation / Memorial Resource Development Corp.		9.3x
Noble Energy, Inc. / Rosetta Resources Inc.		8.9x
Encana Corporation / Athlon Energy Inc.		15.4x
Whiting Petroleum Corporation / Kodiak Oil & Gas Corp.		6.9x
Baytex Energy Corp. / Aurora Oil & Gas Ltd.		4.8x
ExxonMobil Corporation / Celtic Exploration Ltd.		20.6x
Statoil ASA / Brigham Exploration Company		14.6x
BHP Billiton Petroleum (North America) Inc. / Petrohawk Energy Corporation		10.4x
Chevron Corporation / Atlas Energy, Inc.		17.4x
Apache Corporation / Mariner Energy, Inc.		6.4x
ExxonMobil Corporation / XTO Energy Inc.		6.0x
Denbury Resources Inc. / Encore Acquisition Company		8.9x

Based on the results of this analysis, J.P. Morgan selected a multiple reference range for Energen of $35,000 – $55,000 for Adjusted Transaction Value to acreage (based on 160,000 acres per Energen management) and 8.5x – 10.0x for transaction value to estimated EBITDAX for the calendar year ending December 31, 2018.

After applying such ranges to the appropriate metrics for Energen based on the Energen forecasts (assuming Wall Street consensus commodity price estimates, in the case of estimated EBITDAX), the analysis indicated the following implied equity value (adjusted, in the case of the Adjusted Transaction Value to Net Acreage multiple, for an assumed run-rate production value of $2,960 million for the quarter ending June 30, 2018 (assuming $40,000 per Bbl/d for oil, $3,000 per Mcf/d for gas and $16,000 per Bbl/d for NGLs, per Energen management)) per share ranges for Energen common stock (resulting per share values were in all cases rounded to the nearest $0.25 per share):

Energen Implied Equity Value Per Share Range


	Adjusted Transaction Value / Net Acreage	Transaction Value / 2018E EBITDAX
Low	$78.50	$76.75
High	$111.00	$91.75

The disclosure on page 105 of the Proxy Statement in the section captioned “The Merger—Opinion of J.P. Morgan, Energen’s Financial Advisor” is hereby supplemented by revising the first paragraph on the page in its entirety as follows:

During the two years preceding the date of J.P. Morgan’s opinion, J.P. Morgan and its affiliates had commercial or investment banking relationships with Energen and Diamondback and certain of its affiliates, for which J.P. Morgan and such affiliates received customary compensation. Such services during such period have included acting as financial advisor to Energen in connection with its consideration of strategic initiatives, ending in 2018, as a bookrunner of debt securities offerings by Diamondback in October 2016 and December 2016 and dealer manager for a related tender offer in October 2016 and as a bookrunner of equity securities offerings by Diamondback in March 2016 and December 2016. J.P. Morgan is also currently engaged to provide investment banking services to Rattler Midstream Partners LP, an affiliate of Diamondback, which are unrelated to the transaction. In addition, J.P. Morgan’s commercial banking affiliate is an agent bank and a lender under outstanding credit facilities of Energen and Diamondback and one of its subsidiaries, for which it receives customary compensation or other financial benefits. During the two years preceding the date of J.P. Morgan’s opinion, the aggregate fees received by J.P. Morgan from Energen for such services were approximately $0.5 million and from Diamondback and such affiliates were approximately $7.2 million. In addition, J.P. Morgan and its affiliates hold, on a proprietary basis, less than 1% of the outstanding common stock of each of Energen and Diamondback. In the ordinary course of J.P. Morgan’s businesses, J.P. Morgan and its affiliates may actively trade the debt and equity securities or financial instruments (including derivatives, bank loans or other obligations) of Energen or Diamondback for J.P. Morgan’s own account or for the accounts of customers and, accordingly, J.P. Morgan may at any time hold long or short positions in such securities or other financial instruments.

The disclosure beginning on page 111 of the Proxy Statement in the section captioned ““The Merger—Opinion of TPH, Energen’s Financial Advisor” is hereby supplemented by revising the subsection captioned “The Merger—Opinion of TPH, Energen’s Financial Advisor—Precedent Transaction Multiples” in its entirety as follows:

Among the public company transactions reviewed, TPH observed median values of (i) $17.87/boe transaction value/proved reserves and $22.40/boe transaction value/proved reserves for transactions in which the consideration was 100% equity and for all transactions, respectively, (ii) $96,109/boe/d transaction value/production and $99,683/boe/d transaction value/production for transactions in which the consideration was 100% equity and for all transactions, respectively, and (iii) 7.9x/7.3x FY-1/FY-2 transaction value/EBITDAX and 9.3x/7.8x for FY1/FY-2 transaction value/EBITDAX for transactions in which the consideration was 100% equity and for all transactions, respectively. Those observed median values were compared to the corresponding values of $21.15/boe transaction value/proved reserves, $96,422/boe/d transaction value/production, and 9.2x/6.8x FY-1/FY-2 transaction value/EBITDAX for Energen, in each case based on an Energen transaction value of $9,391 million (based on market price as of August 10, 2018).

Additionally, TPH observed the premiums per share paid by an acquirer company (in each case as compared to the share price of the target company one day prior to the announcement of a transaction) in the 17 selected U.S. upstream corporate transactions since 2004 with a transaction value of over $1 billion. TPH observed that (i) with respect to all such transactions considered, the median premium paid was 33.7%, and (ii) with respect to transactions involving 100% stock consideration, the median premium paid was 21.7%. These observed premiums were then compared to the premium to be paid with respect to the merger, based on Energen’s and Diamondback’s share price on August 10, 2018, of 20.2%.

With respect to Permian Basin private company/asset transactions, TPH observed the following multiples of transaction value per adjusted net acre (assuming $30,000 boe/d for current production) and transaction value per boe/d of current production:
