MACH NATURAL RESOURCES LP 8-K

What Happened

• Mach Natural Resources LP (MNR) entered an underwriting agreement on April 6, 2026 with Morgan Stanley & Co. LLC for a secondary offering by selling unitholders of 9,000,000 common units, with a 30‑day option for the underwriter to buy up to an additional 1,350,000 units. The offering closed on April 8, 2026.
• The Company did not receive any proceeds from the sale (the units were sold by existing unitholders). Tom L. Ward, the Company’s CEO, through related trusts, foundations and certain affiliated entities, purchased 153,256 common units in the offering at the public offering price. The offering was made under a Form S-3 registration statement (File No. 333-291166) declared effective Dec 12, 2025; the final prospectus supplement is dated Apr 6, 2026. Legal opinions from Kirkland & Ellis LLP relating to the offering are attached to the filing.

Key Details

• 9,000,000 common units sold by Selling Unitholders; underwriter option for up to 1,350,000 additional units (30 days).
• Offering closed April 8, 2026; registration statement on Form S-3 (declared effective Dec 12, 2025).
• Company received zero proceeds from the sale; any proceeds from option units would also go to Selling Unitholders, not the Company.
• CEO Tom L. Ward and affiliated entities acquired 153,256 units at the public offering price. Underwriting performed by Morgan Stanley; customary indemnities and legal opinions were provided.

Why It Matters

• This was a secondary (sell-side) offering by existing unitholders, so it did not raise cash for the company or dilute existing limited partners through new issuance to the company.
• The sale increases the number of units available to public investors (and could increase if the underwriter exercises its option), and the filing documents the transaction terms, underwriter relationships, and legal opinions that support the offering’s completion.
• CEO participation (153,256 units purchased) is a factual detail investors may note when evaluating insider interest following the offering.
