Saia Reports Second Quarter Earnings Per Share of $0.21
Revenues were $266 million, an increase of 15 percent from prior year quarter

JOHNS CREEK, GA. — July 27, 2011 — Saia, Inc. (NASDAQ: SAIA), a leading multi-regional less-than-truckload (LTL) carrier, today reported improved second quarter 2011 results on stronger revenue, improved pricing fundamentals and increased tonnage.

Second Quarter 2011 Compared to Second Quarter 2010 Results

	•		Revenues were $266 million, an increase of 15 percent.
	•		Operating income increased 41 percent to $8.3 million compared to $5.9 million.
	•		Earnings per share were $0.21 vs. $0.12.
	•		Operating ratio was 96.9 vs. 97.5.
	•		LTL tonnage increased by 4.5 percent as LTL shipments per workday were up 3.0 percent with a 1.5 percent increase in weight per shipment.
	•		LTL yield was up 9.6 percent due to the impact of higher fuel surcharge and measured pricing actions.

“I continue to be encouraged that improvements in the transportation landscape have permitted us to employ prudent pricing actions across our customer base. We continue to achieve increases in contract renewals which are greater this quarter than those secured in the first quarter. As in prior quarters, our measured pricing actions have resulted in deselecting a number of unprofitable accounts. This is part of a slow but steady improvement plan and is a welcome change from the challenging pricing and volume environment in which we had been operating the past several years,” said Rick O’Dell, president and chief executive officer.

“The quarter was not without its challenges including significantly higher costs from health care, purchased transportation, maintenance and self insurance costs. We continue to focus on service and productivity initiatives which will produce improvements in terminal cost per freight bill. Our safety and cargo claims programs are at the heart of our initiatives across the network,” continued O’Dell.

“As the result of increased demand by shippers in our newer geography, we took the opportunity to open a new terminal in Bloomington, IL, allowing us to offer 100% coverage of Illinois. The new terminal in Bloomington supports our strategy of providing 100% coverage in the states which we operate and contributes to our efforts to build density in our geographic footprint.

“We also continue to move forward with our initiatives to improve pricing and remain focused on our cost and quality initiatives. As always, Saia’s dedicated employees remain focused on providing best in class customer service. We believe Saia is well positioned to take advantage of any future industry consolidations and to capitalize on what appears to be improving industry fundamentals,” O’Dell said.
