ORDER INSTITUTING CEASE-AND-
DESIST PROCEEDINGS PURSUANT TO 
SECTION 21C OF THE SECURITIES 
EXCHANGE ACT OF 1934, MAKING 
FINDINGS, AND IMPOSING A CEASE-
AND-DESIST ORDER  

  
I. 

 
 The Securities and Exchange Commission (“Commission”) deems it appropriate that cease-
and-desist proceedings be, and hereby are, instituted pursuant to Section 21C of the Securities 
Exchange Act of 1934 (“Exchange Act”), against Sourcerock Group, LLC (“Sourcerock” or 
“Respondent”).   

 
II. 

 
 In anticipation of the institution of these proceedings, Respondent has submitted an Offer 
of Settlement (“Offer”), which the Commission has determined to accept. Solely for the purpose of 
these proceedings and any other proceedings brought by or on behalf of the Commission, or to 
which the Commission is a party, and without admitting or denying the findings herein, except as 
to the Commission’s jurisdiction over it and the subject matter of these proceedings, which are 
admitted, Respondent consents to the entry of this Order Instituting Cease-and-Desist Proceedings 
Pursuant to Section 21C of the Securities Exchange Act of 1934, Making Findings, and Imposing a 
Cease-and-Desist Order (“Order”), as set forth below.   
 

III. 
 
 On the basis of this Order and Respondent’s Offer, the Commission finds1 that:  
 

 
 

 
1 The findings herein are made pursuant to Respondent’s Offer of Settlement and are not binding 
on any other person or entity in this or any other proceeding.  



 2 

 
Summary  

 
1. These proceedings concern a violation of Rule 105 of Regulation M under the 

Exchange Act [17 C.F.R. § 242.105] (“Rule 105”) by Sourcerock, a registered investment adviser. 
In November 2022, Sourcerock purchased equity securities for the accounts of six of its private 
fund clients (“Sourcerock Funds”) in a covered offering after Sourcerock had sold short the same 
securities on behalf of the Sourcerock Funds during Rule 105’s restricted period.  

 
Respondent 

 
2. Sourcerock, a Delaware limited liability company based in Denver, Colorado, is 

registered with the Commission as an investment adviser and advises the Sourcerock Funds. In its 
most recent annual updating amendment to Form ADV filed on March 26, 2025, Sourcerock 
reported having approximately $2.6 billion in regulatory assets under management.  
 

Rule 105 
 

3. Rule 105 makes it unlawful for any person to purchase equity securities from an 
underwriter, broker, or dealer participating in a covered public offering if that person sold short the 
security that is the subject of the offering during the restricted period as defined in the rule, absent 
meeting the conditions of an exception. See 17 C.F.R. § 242.105(a) and (b). The Rule 105 
“restricted period” is the shorter of the period: (1) beginning five business days before the pricing 
of the offered securities and ending with such pricing; or (2) beginning with the initial filing of a 
registration statement or notification on Exchange Act Form 1-A or 1-E and ending with the 
pricing. See 17 C.F.R. § 242.105(a)(1) and (a)(2). 

 
4. The Commission adopted Rule 105 “to foster secondary and follow-on offering 

prices that are determined by independent market dynamics and not by potentially manipulative 
activity.” Short Selling in Connection with a Public Offering, Exchange Act Release No. 34-
56206, 72 Fed. Reg. 45094 (Aug. 10, 2007) (effective Oct. 9, 2007). Rule 105 is prophylactic and 
prohibits the conduct irrespective of the short seller’s intent. See id. 

 
Facts 

 
5. After market close on November 3, 2022, Magnolia Oil & Gas Corporation 

(“Magnolia”) (NYSE: MGY) announced a proposed underwritten offering of 7,500,000 shares 
(“Magnolia Offering”). Before market open on November 4, Magnolia priced the shares for the 
Magnolia Offering. The Rule 105 restricted period for the Magnolia Offering, therefore, was from 
October 28, 2022, through November 3, 2022 (“Magnolia Restricted Period”). 

 
6. Between November 1 and 2, 2022, during the Magnolia Restricted Period, 

Sourcerock sold short 123,800 Magnolia shares on behalf of the Sourcerock Funds.  
 



 3 

7. On November 4, 2022, Sourcerock purchased a total of 450,000 shares as part of 
the Magnolia Offering in the same Sourcerock Funds in which Sourcerock had engaged in short 
selling during the Magnolia Restricted Period. 

 
8. Sourcerock did not qualify for an exception to Rule 105 when Sourcerock 

purchased shares for the accounts of the Sourcerock Funds in the Magnolia Offering.  
 
9. The Sourcerock Funds improperly benefited from Sourcerock’s trading set forth 

above by acquiring Magnolia shares at a discount from the market price. 
 

Violations 
 

10. As a result of the conduct described above, Sourcerock violated Rule 105 of 
Regulation M under the Exchange Act. 

 
Sourcerock’s Cooperation and Remedial Efforts 

 
11. In determining to accept the Offer, the Commission considered Sourcerock’s 

cooperation with the staff’s investigation. For example, Sourcerock cooperated with the staff’s 
investigation by voluntarily gathering documents and communications, conducting a review for 
prior violations (of which none were found), and presenting to the staff, including on the firm’s 
efforts at compliance.  

 
12. In determining to accept the Offer, the Commission also considered Sourcerock’s 

remediation. After Sourcerock discovered the Rule 105 violation, it undertook certain remedial 
acts, including promptly conducting a review of its trading history and updating its related trading 
processes. Sourcerock also updated its compliance policies and procedures to prevent future 
violations of Rule 105. 
 

IV. 
 

 In view of the foregoing, the Commission deems it appropriate to impose the sanctions 
agreed to in Respondent’s Offer. 
 
 Accordingly, it is hereby ORDERED that: 
 
 A. Pursuant to Section 21C of the Exchange Act, Respondent cease and desist from 
committing or causing any violations and any future violations of Rule 105 of Regulation M under 
the Exchange Act. 
 
 B. Respondent shall, within 10 days of the entry of this Order, pay a civil money 
penalty in the amount of $250,000 to the Securities and Exchange Commission for transfer to the 
general fund of the United States Treasury, subject to Exchange Act Section 21F(g)(3). If timely 
payment is not made, additional interest shall accrue pursuant to 31 U.S.C. § 3717. Payment must 
be made in one of the following ways: 



 4 

(1) Respondent may transmit payment electronically to the Commission, which 
will provide detailed ACH transfer/Fedwire instructions upon request;  

 
(2) Respondent may make direct payment from a bank account via Pay.gov 

through the SEC website at http://www.sec.gov/about/offices/ofm.htm; or  
 
(3) Respondent may pay by certified check, bank cashier’s check, or United 

States postal money order, made payable to the Securities and Exchange 
Commission and hand-delivered or mailed to:  

 
Enterprise Services Center 
Accounts Receivable Branch 
HQ Bldg., Room 181, AMZ-341 
6500 South MacArthur Boulevard 
Oklahoma City, OK 73169 

 
Payments by check or money order must be accompanied by a cover letter identifying 

Sourcerock as a Respondent in these proceedings, and the file number of these proceedings; a copy 
of the cover letter and check or money order must be sent to Kimberly L. Frederick, Assistant 
Director, Division of Enforcement, Securities and Exchange Commission, 1961 Stout St., Suite 
1700, Denver, CO 80294. 
 
 C.  Amounts ordered to be paid as civil money penalties pursuant to this Order shall be 
treated as penalties paid to the government for all purposes, including all tax purposes. To preserve 
the deterrent effect of the civil penalty, Respondent agrees that in any Related Investor Action, it 
shall not argue that it is entitled to, nor shall it benefit by, offset or reduction of any award of 
compensatory damages by the amount of any part of Respondent’s payment of a civil penalty in 
this action (“Penalty Offset”). If the court in any Related Investor Action grants such a Penalty 
Offset, Respondent agrees that it shall, within 30 days after entry of a final order granting the 
Penalty Offset, notify the Commission's counsel in this action and pay the amount of the Penalty 
Offset to the Securities and Exchange Commission. Such a payment shall not be deemed an 
additional civil penalty and shall not be deemed to change the amount of the civil penalty imposed 
in this proceeding. For purposes of this paragraph, a “Related Investor Action” means a private 
damages action brought against Respondent by or on behalf of one or more investors based on 
substantially the same facts as alleged in the Order instituted by the Commission in this 
proceeding. 
 
 By the Commission.
