Exhibit 99.1

Saia Reports Record First Quarter Earnings per Share of $0.85

JOHNS CREEK, GA. – May 1, 2019 – Saia, Inc. (NASDAQ: SAIA), a leading transportation provider offering multi-regional less-than-truckload (LTL), non-asset truckload, expedited and logistics services, today reported first quarter 2019 financial results.  Diluted earnings per share in the quarter were $0.85 compared to $0.80 in the first quarter of 2018.

First Quarter 2019 Compared to First Quarter 2018 Results

“In the first quarter we saw continued success with selling our value proposition to customers and we were able to increase LTL revenue per hundred weight by 10.6% including average contractual renewal rates that rose 9.8% in the quarter.  This increase in LTL yield marked the 35^th consecutive quarter of year-over-year improvement, reflecting our improving service reach and record low cargo claims ratio”, said Saia Chief Executive Officer, Rick O’Dell.

“While first quarter 2019 diluted earnings per share were a first quarter record, we are disappointed that we were not able to bring more of our strong yield improvements to the bottom line.  The first quarter is typically the seasonally softest period of the year and we simply incurred too many weather-related volume and cost impacts to reach our profitability goals in the period.  Winter weather throughout the quarter caused parts of our network to be interrupted on an almost weekly basis”, O’Dell continued.

“We opened one additional terminal in the Northeast in the first quarter and have plans to open an additional four or five in that region over the remainder of the year.  Broadening our direct service coverage area is resonating with customers and nearly 70% of our business in and out of the Northeast is coming from customers who were already using Saia in other parts of the country”, concluded O’Dell.  

Financial Position and Capital Expenditures

Total debt was $148.9 million at March 31, 2019 and inclusive of the cash on-hand, net debt to total capital was 17.2%.  This compares to total debt of $142.6 million and net debt to total capital of 19.0% at March 31, 2018.

Net capital expenditures in the first quarter of 2019 were $56.5 million including equipment acquired with capital leases.  This compares to $52.1 million in net capital expenditures in the first quarter of 2018.  In 2019, we anticipate net capital expenditures of $275-$300 million.
