**FOR IMMEDIATE RELEASE**

Saia, Inc. Reports Record 2006 Results from Continuing Operations
$1.74 earnings per share including $0.17 restructuring and integration charges

DULUTH, Ga. — January 31, 2007 — Saia, Inc. (NASDAQ: SAIA), a leading multi-regional less-than-truckload (LTL) carrier (“the Company”), reported 2006 results with revenue of $875 million from continuing operations, an increase of 16 percent from 2005. 2006 operating income from continuing operations was $50.0 million including $4.1 million in restructuring and integration expenses, compared with 2005 operating income of $50.4 million which included a $7.0 million pretax real estate gain. Income from continuing operations increased to $25.9 million in 2006 from $25.2 million in 2005. Earnings per share from continuing operations were $1.74, including charges for restructuring and integration expenses, compared to $1.67 in 2005 which included $0.29 in real estate gain.

“For the fifth consecutive year, Saia produced growth and improvement in our core operating results. Earnings per share from continuing operations were $1.74 which included the impact of $0.17 in restructuring and integration related costs. This compares favorably to our $1.67 earnings per share from the prior year which included $0.29 per share in real estate gain. Our customers responded to Saia’s strong service offerings which resulted in 16 percent revenue growth for the year,” said Rick O’Dell, President and Chief Executive Officer. “In 2006, Saia again built upon our track record of growth and margin improvement. Saia further advanced our positioning for long-term profitable growth and shareholder value creation, particularly with our fourth quarter acquisition of The Connection.”

2006 highlights are summarized as follows:

• Operating ratio from continuing operations excluding real estate gain, restructuring and integration related costs improved to 93.8 from 94.2

• Excluding The Connection

• LTL tonnage growth of 9%

• LTL yield increase of 6%

For the fourth quarter, Saia reported earnings per share from continuing operations of $0.36 which included charges of $0.09 per share in restructuring and integration expenses compared to $0.69 in the prior year which included a benefit of $0.29 for the real estate gain. Fourth quarter revenue was $219 million, up 8 percent from prior year. Operating income from continuing operations was $10.5 million which includes $2.0 million of restructuring and integration expenses, which compares to the prior year quarter operating income of $18.2 million which included a $7.0 million real estate gain.

Fourth quarter 2006 highlights include:

• Operating ratio from continuing operations excluding real estate gain, restructuring and integration related costs improved to 94.3 from 94.5

• Excluding The Connection

• LTL tonnage growth of 2%

• LTL yield increase of 4%

“In light of recent economic conditions and more difficult comparisons, I am pleased with our marketing success and fourth quarter revenue growth,” O’Dell said. “While we improved our operating ratio excluding real estate gain, restructuring and integration charges, our cost performance was challenged by the weaker than expected volumes, as well as unfavorable trends in workers’ compensation and health care expenses.”

On November 20th, Saia announced the acquisition of The Connection Company, a less-than-truckload carrier operating in four states. Fourth quarter results included an additional $7.0 million in revenue with no contribution to operating income and we incurred $1.5 million of costs related to the integration. “I am excited about 2007 as the acquisition of The Connection will provide opportunities for synergy revenue to and from the states of Michigan, Indiana, Ohio and Kentucky. We are on schedule to complete our February 12th integration and opening of the synergy lanes in March,” continued O’Dell.

On November 27th, Saia announced the authorization of an additional $25 million share repurchase program. During the quarter, Saia completed the previously approved program and repurchased shares under the new program for a total of $8.9 million repurchased during the quarter.

“We continue to focus on improving Saia’s financial and operational performance. With our recent acquisition and our goal of expanding geographically to increase market share, we believe Saia has a solid foundation to deliver strong value to both customers and shareholders,” said Jim Darby, Saia’s Vice President of Finance and Chief Financial Officer.

Financial Position and Capital Expenditures
Total debt was $110 million at December 31, 2006 with net debt to total capital of 32.8 percent, as a result of the Company’s $10.7 million cash balance at December 31, 2006. This compares to net debt to total capital of 30.0 percent at December 2005.

Consolidated net capital expenditures from continuing operations for 2006 were $91 million. The Company is planning net capital expenditures in 2007 of approximately $85 million which includes up to $35 million for real estate projects.
