Devon Energy is buying Grayson Mill Energy's Williston Basin business in a cash-and-stock deal valued at $5 billion as consolidation in the oil and gas sector ramps up.

The transaction includes $3.25 billion in cash and $1.75 billion in stock.

Grayson Mill Energy, based in Houston, is an oil and gas exploration company that received an initial investment from private equity firm EnCap Investments in 2016.

The firm appears to be stepping back from energy sector as it sells off assets. Last month EnCap-backed XCL Resources sold its Uinta Basin oil and gas assets to SM Energy Co. and Northern Oil and Gas in a transaction totaling $2.55 billion. EnCap had another deal in June as well, selling some assets to Matador Resources for nearly $2 billion.

Devon said Monday that the deal significantly expands its position in the Williston Basin with the addition of 307,000 net acres. The basin spans parts of Montana, North Dakota, South Dakota and Canada.

The company anticipates that production from the acquired properties will be maintained at approximately 100,000 barrels of oil equivalent per day next year.

The deal is targeted to close by the end of the third quarter.

Devon said its board will expand its buyback authorization by 67 percent to $5 billion through the middle of 2026. The company also anticipates the deal adding to its dividend payout beginning next year.

Shares of Devon Energy Corp., based in Oklahoma City, fell more than 2.5 percent Monday.

In March, Devon Energy led Houston-based geothermal startup Fervo Energy's $244 million funding round.

A new U.S. News & World Report ranking of the best employers has named two dozen Houston-based companies among the best companies to work in the South, and more than half are part of the region's booming energy sector.

U.S. News' prestigious "2026-2027 Best Companies to Work For" ratings examine 3,900 public and privately owned companies across 14 industries to help employees and job seekers make decisions about workplaces that may be a good fit.

Each company is rated on a scale of 1-5 across six metrics: quality of pay and benefits; work-life balance and flexibility; job and company stability; physical and psychological comfort; belongingness and esteem; and career opportunities and professional development.

"Job seekers' definitions of 'best' evolve with their needs," said Carly Chase, vice president of Careers at U.S. News. "From new grads in the AI era and seasoned pros seeking a career change, to HR leaders researching organizational trends, the ratings are a central hub that highlights businesses that U.S. News found effectively support their staff."

The number of employers headquartered in the Houston area that made the cut for 2026-2027 has skyrocketed over previous years. A total of 24 local public and private companies made the list this year, up from 16 companies in 2024 and 11 in 2025.

The highest concentration of top employers is located in Houston proper (20), followed by two companies in The Woodlands and one each in Kingwood and Spring.
