"Very poor weather, major repairs to a lock on the Gulf Intracoastal Waterway and rapidly escalating fuel prices, not lower business levels, are the factors causing Kirby to revise its first quarter forecast," were a few reasons that Joe Pyne, Kirby Corporation's President CEO, cited for the company's lowering of its earnings guidance for the 2003 first quarter to $.26 to $.30 per share from previous guidance of $.36 to $.40 per share. Navigational delays due to fog along the Gulf Coast, both high and low water issues on the Mississippi River, and major repairs to a critical lock on the Gulf Intracoastal Waterway, have resulted in increased transit times. Navigational delays increase transit times, which reduce revenues and increase operating expenses.
