The firm prefers to take controlling ownership stakes in companies with EBITDA between $3 million to $15 million. Typical equity investments range from $10 million to $50 million. Stone Capital brings an operations-focused approach to its investments – its operating partners have hands-on management experience running mid-sized companies across a range of industries. The firm has expertise in helping portfolio companies drive growth through add-on acquisitions.
Media and Telecom Have Been Major Investment Areas
Stone Capital has deployed significant capital in both the media and telecommunications industries over the years. Major media investments have included the acquisitions of Triad Media, Day Communications, and Video Services Corp. On the telecom side, Stone Capital acquired FiberLight in 2005, one of its most notable deals. FiberLight operates a high-capacity fiber optic network with over 1,300 route miles of fiber, providing mission-critical data and optical bandwidth services to wireless, enterprise, and government customers. Under Stone Capital’s ownership, FiberLight achieved substantial growth through network expansion and multiple add-on acquisitions.
Stone Capital Exited FiberLight in 2010 in a $730 Million Sale
In 2010, Stone Capital sold FiberLight in a $730 million transaction, netting an impressive 5x return on invested capital over a five year holding period. The sale of FiberLight generated outsized profits for Stone Capital and its limited partners. Stone Capital’s growth strategy for FiberLight, centered on strategic acquisitions and network expansion, helped transform the company into one of the largest competitive fiber optic networks in the U.S. This highly successful investment demonstrates Stone Capital’s operational expertise in the telecom sector.
