Formed in 2010, Cottonwood Acquisitions is a family office that acquires and operates small to mid-sized businesses. We have made 12 platform acquisitions. We take a generalist approach to industries, most frequently purchase from owner entrepreneurs and have helped the Seller retire in 9 of our 12 transactions. We take a long term, evergreen approach to investing, rather than looking to flip businesses in 3-5 years. We are down to earth, midwest guys that have impeccable references for being nice people and easy to work with.

Firms in the Oil & Gas Exploration & Production Family Offices directory are ordered based on recent deal activity on Axial. The default order reflects observed market signals rather than a subjective ranking of firm quality.

Each profile provides information about the firm’s areas of focus, transaction criteria, and relevant activity on Axial’s M&A platform. Together, these details provide a clearer view of where a firm is active and the types of companies and opportunities most relevant for it.

Based on activity on Axial’s M&A platform, the core revenue range for Oil & Gas Exploration & Production Family Offices is $5M-$22M, with a core EBITDA range of $1M-$4M. Company size can be an important indicator of fit, as firms often concentrate their experience, resources, and transaction activity within particular segments of the market.

Relevant Energy & Utilities experience can be an important consideration when evaluating a firm. Familiarity with the sector can provide a stronger understanding of its business models, market dynamics, valuation considerations, and transaction environment. The 89 firms included in this directory provide a starting point for identifying firms with relevant experience and activity in Energy & Utilities.

Not necessarily. Many firms are active across multiple industries, so inclusion in the Oil & Gas Exploration & Production Family Offices directory reflects relevant experience or activity in Energy & Utilities, rather than an exclusive sector focus.
