BOULDER, Colo. – 
      Zayo Group Holdings, Inc. (NYSE: ZAYO) today announced that Scott Drake
      has been elected by shareholders and Yancey Spruill has been appointed
      by the Board to the company’s Board of Directors, effective today. Drake
      is replacing Nina Richardson, whose term expired yesterday. Spruill is
      replacing Phil Canfield, who resigned following the November Board
      meeting, after completing a six-year tenure. Phil’s departure follows
      GTCR’s exit of its ownership position in the summer of 2018.
    
      “I’d like to thank Nina and Phil for their contributions. Nina’s
      operational expertise was valuable as we’ve continued to expand
      internationally. Phil provided insightful guidance over a critical
      period in Zayo’s history and was instrumental in many of Zayo’s
      acquisitions, including AboveNet. GTCR saw the tremendous opportunity in
      Zayo’s thesis and as a result achieved a strong return on their
      investment,” said Dan Caruso, chairman and CEO at Zayo.
    
      “Both Scott and Yancey are seasoned leaders of multiple successful
      international tech companies. Scott has a strong track record of
      leadership, which extends to global business strategy, operational
      execution and company culture. Yancey has helped steer two Silicon
      Valley-like companies to impressive growth and successful IPOs. They
      have the complementary skills and insight that are relevant for Zayo’s
      current stage of growth,” added Caruso.

      device manufacturer in Mountain View, California. He previously served
      as president and CEO of a public medical device manufacturer, The
