Saia Inc.'s operating profit margin has displayed some fluctuations over the past eight quarters. In Q4 2023, the operating profit margin was 16.01%, slightly lower than the previous quarter's 15.81%. This decline followed a consistent trend of decreasing margins since Q2 2023, when the margin was at its highest level of 16.70%. Comparing with the same quarter in the previous year, Q4 2022, the operating profit margin has decreased from 16.85% to 16.01%.

Overall, Saia Inc. has shown a generally stable operating profit margin range between 15.66% and 17.27% over the past two years. However, the recent downward trend raises questions about the company's ability to maintain its historical profitability levels. Further analysis of Saia Inc.'s cost structure and revenue generation would be necessary to understand the drivers behind the fluctuations in its operating profit margin.
