11. M&A Considerations A number of factors to consider in pursuing any M&A transaction

12. Process Considerations Public Offering Versus Sale • Initial Public Offering • Sale of Business PROS: • Primary shareholders retain voting control and existing management continues to execute the strategic vision of the business • Proceeds from an IPO can be used to increase scale through acquisitions or fuel organic growth • Shareholders can participate in potential upside should the business continue to execute and market conditions remain favorable CONS • The organization must take on the costs associated with public filing and compliance requirements while managing greater scrutiny by investors • An IPO lock-up prevents current shareholders from achieving immediate liquidity • There is a high degree of uncertainty in future capital market conditions • There is the potential for a downside in valuation should the business lose traction PROS: • Reduces or eliminates execution risks of the current business plan as well as future capital market uncertainties • M&A valuation includes control premium • Can offer a more immediate path to liquidity for current shareholders • Avoids the costs associated with being a public company • Partnering increases opportunity to cross-sell and up-sell through larger distribution platform and gain rapid critical mass to better compete CONS: • Primary shareholders relinquish voting control and new management executes the strategic vision of the company • Cash transactions eliminate the upside participation in the pro forma company • Integration and execution risk of combined business
