Now I would like to introduce Terri Pizzuto, the Chief Financial Officer of Hub Group
Thanks, Jeremy, and thanks, everyone, for being with us today. I want to begin by covering 3 main themes: first, Intermodal volumes were strong, with Hub segment volume up 16% and total Intermodal volume, including Mode, up 34%; second, Mode's profitability continues to improve; and third, we completed our restructuring in truck brokerage and the new organization is energized.
Here are the key numbers for the fourth quarter. Hub Group's revenue increased 59% to $763 million. Excluding one-time cost of $1 million, Hub Group's diluted earnings per share increased 41% to $0.48. Now I'll discuss details for the quarter. As a reminder, we now report 2 distinct business segments: Hub and Mode. Mode segment includes only the business that we acquired as of April of 2011. The Hub segment includes all business other than Mode. When we say Hub group as opposed to just Hub, we're referring to the consolidated results for the entire company including both the Mode and Hub segments.
First, I'll talk about the financial performance of the Hub segment. Hub segment generated revenue of $577 million which is a 20% increase over last year. Taking a closer look at Hub's business line, Intermodal revenue increased 23%. This change includes a 16% volume increase and a 7% increase for fuel, price and mix. Directionally, fuel has a larger increase in price and mix was negative. 250 basis points of this volume increase came from fleet boxes that we sold to Mode agents.
We're excited that this was the eighth straight quarter of double-digit Intermodal volume growth. We continue to see growing customers converting freight from truck to Intermodal. A large part of the truck conversion freight is in our local east market, which was up 19% for the quarter. Because of the growth in this market, our average Intermodal length of haul was down 1%.
Truck brokerage revenue was up 3% on 3% lower volume. The truck brokerage business unit went through a restructuring this year. The team is very confident that we'll be successful winning new business that will result in growth in the second half of the year.
Logistics revenue was 27% higher than last year. Most of that growth came from existing customers. The Hub segment's gross margin increased by $4.5 million, due to significant growth in Intermodal gross margin and slight growth in logistics margin, partially offset by a small decline in truck brokerage margin.
Intermodal margin is up because of volume growth and our focus on doing more of our own drayage. Hub's gross margin, as a percentage of sales, was 10.6%. That's down 120 basis points compared to last year's 11.8% margin.
There are 3 main reasons why the margin percentage is down from last year: #1, logistics' margin is down 200 basis points since we're doing more transactional as opposed to management fee business; #2, truck brokerage yield is down 85 basis points; and #3, Intermodal yield is down since we had higher than anticipated cost increases from key carriers, and our equipment did not turn as quickly as last year.
Hub's costs and expenses were flat at $37.4 million in the fourth quarter of 2011 and 2010. Salaries and benefits includes $330,000 of severance-related expenses that we classified as a one-time cost. We also recorded $170,000 of one-time expense related to office closure.
Finally, we're happy that operating margin for Hub increased from 4% last year to 4.2% this year, excluding one-time costs.
Now I'll discuss results for our Mode segment. Mode's revenue was $195 million. The revenue breakdown is $94 million in Intermodal, $76 million in truck brokerage and $25 million in logistics. Compared to last year, revenue at Mode was up 6%. Mode's gross margin was $22.7 million. Gross margin as a percentage of sales was 11.6%. Mode agents decided to use Hub fleet containers for 12% of their Intermodal loads. Mode's total cost and expenses were $19.2 million. Included in these costs are one-time expenses totaling $500,000 that relate mostly to technology transition.
To summarize our one-time costs, on the Hub side, we had the $330,000 of severance-related costs and the $170,000 of office closing costs. On the Mode side, we had a $0.5 million of mostly technology transition-related costs, for a grand total of $1 million. Operating margins for Mode was 1.8%. If you exclude one-time costs, it was 2%.
Turning to our headcount, we had 1,349 employees, excluding drivers, at the end of December. That includes 1,188 Hub employees and 161 Mode employees. Hub headcount went up 17 people, and Mode headcount went down 22 people since September. The majority of the increase in employees at Hub were in the logistics group.
Now I'll discuss 2012 full-year earnings guidance. In 2012, we're comfortable that our diluted earnings per share will be within the current analyst range of between $1.85 and $2.20. Our weighted average diluted shares for 2012 are estimated to be $37 million.
We think that our quarterly cost and expenses, including Mode, will range between $61 million and $63 million in 2012.
Turning now to our balance sheet and how we used our cash. We ended the quarter with $49 million in cash and no debt. During the quarter, we spent $19.6 million on capital expenditures. $16 million was for containers, $1 million was for our building addition at Comtrak and the remainder was for technology investments. We think that we'll spend between $50 million and $60 million on capital expenditures in 2012. Between $20 million and $30 million is for our new corporate headquarters, which is a 2-year project. $13 million is for containers, and the remainder is for technology investments.
To wrap it up for the financial section, the 41% increase in operating income for the quarter was a great finish to the year.
And now, you'll hear from our CEO, Dave Yeager.
