Mike Costello
Costello Capital Management, LLC
Serving Hamilton County, TN
Mike Costello, our managing member, has consulted several business owners relating to the successful sale of their ownership interests. A recent example occurred in August 2021, prior to his retirement from Elliott Davis, when he was retained as a consultant with respect to the sale of a middle market company located in the Tennessee Valley. In this case, he provided assistance to the company’s owner and management team, resulting in the successful sale to a strategic buyer (a public company in the industry) in December, 2021 for $58 million. In July, 2022, he received a request from another Tennessee Valley middle market company to perform business broker services. These events motivated Costello to serve as a business broker. As a result, he retired from Elliott Davis and formed Costello Capital Management, LLC (“CCM”) in October, 2022. CCM is already actively engaged with other regional clients exploring the sale of their businesses. CCM is uniquely qualified to determine the best approach for marketing a business entity for sale. This could include going to: -private equity groups (financial buyers), -industry members (as mentioned above), or -the local market (including networking with CPAs, bankers, attorneys or known potential buyers), depending upon the size of the business. Costello’s experience and in-depth knowledge of business transactions is beneficial at every stage of a business transaction: determining the optimal sales process, establishing an appropriate sales price, negotiating to realize the targeted sales price and then managing the transaction to a successful closing.
