ABOUT

About Costello Capital Management, LLC

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.

Costello owned business interests in several companies over the years prior to forming CCM, including: · Costello Strain & Company, · Center for Financial Strategies, · Southeast Financial Advisors, · Costello Forensic Accounting, · Joseph Decosimo & Company, · Decosimo Corporate Finance, · Elliott Davis, and · Costello Advisory Services. Mike authored numerous articles (on accountancy and other financial issues) and presented at professional seminars throughout the US. During his career, he has been an active member of the business community and has been recognized for his contributions and achievements by the Chattanooga Jaycees, the Chattanooga Chamber of Commerce, the Tennessee Society of CPAs, the National Association of Certified Valuators and Analysts and the Small Business Administration. Mike has also been an active UTC alumni, serving as chair of the UC Foundation. He received the UTC Outstanding Service Award in 2021.

METHODOLOGY

What we observe

DealLedger publishes what is publicly displayed. Broker records aggregate every observed listing tied to this firm across our sources. Counts above reflect distinct listings observed, not closed transactions confirmed by the broker.

We do not have direct visibility into which listings sold. When a listing stops appearing in our scrapes, we mark it as no longer observed — but we do not claim it sold. Some close; some withdraw; some are re-listed under a new ID; some are simply missed by our scraper. We surface the observation; you draw the conclusion.
