The National Venture Capital Association (NVCA) has joined with the U.S. Chamber of Commerce and other organizations to release “Expanding The On-Ramp: Recommendations to Help More Companies Go and Stay Public,” a report providing public policy recommendations to encourage more U.S. public companies. The report was produced in partnership with a number of organizations, including the Center for Capital Markets Competitiveness, Nasdaq, TechNet, SIFMA, Biotechnology Innovation Organization, American Securities Association and Equity Dealers of America. “Six years after the passage of the Jobs Act, we now have a good understanding of what further reforms are needed to make it easier for venture-backed companies to enter the public markets and succeed once there,” said Bobby Franklin, President and CEO of NVCA. “Our goal is for this report to build off the success of the Jobs Act, which made it easier to go public, and provide a critical set of policy changes to make it more attractive to be a public company. The venture capital industry has historically fed the IPO pipeline. Reversing the decline in the number of U.S. public companies is a top priority, and this report is a significant step for our efforts. We look forward to working with Congress, the SEC and other stakeholders to make these reforms a reality.”
