 With Saia having opened seven terminals in 2021, and with plans to add another 10 to 15 in the coming year, CEO Fritz Holzgrefe took the opportunity of his companys quarterly earnings call with analysts Wednesday to talk about the challenges and benefits of building that new capacity. The earnings call came a few hours after Saia NASDAQ: SAIA released its quarterly earnings that showed its operating ratio had strengthened to 84.2 in the fourth quarter from 89.4 a year earlier, its revenue per hundredweight excluding fuel improved 14 to 18.89 from the fourth quarter of 2020, and total revenue for the company rose 29.5 from the final quarter of 2020 and 25.5 for the full year.
