Historically, the port relied on high-volume, low-value bulk cargoes such as phosphate and petroleum for the majority of its business. However, the port’s diversification over the last decade, including cruise activity and increased container operations, has enabled the port to expand its revenue mix, as well. “We continue to be committed to strong fiduciary responsibility and to ongoing investments that make the most sense for the Port of Tampa, both in the short term and the long term,” Richard Wainio, port director and chief executive, said. “It is fitting that Fitch Ratings has again recognized this commitment, and we are pleased to yet again share this great result with the port community and our stakeholders.” One of the nation’s largest and most cargo-diverse seaports, the Port of Tampa is the largest economic engine in west-central Florida, responsible for nearly 100,000 jobs and $8 billion in annual economic impact.
