Thanks, Melanie, and thank you all for being with us today. We had a record second quarter, and I'd like to highlight 3 points. First, intermodal volumes were solid, with Hub segment volume up 9%, which met our expectation. Second, despite the economic uncertainty, operating income was up 13% after adjusting 2011 for onetime costs. And third, truck brokerage results were lower than we expected, and we think that the second half of the year will be challenging.
Here are the key numbers for the second quarter. Hub Group's revenue increased 4% to $778 million. Hub Group's diluted earnings per share was $0.46. Earnings per share are up 15% compared to 2011 adjusted EPS. 2011 diluted earnings per share, excluding onetime costs related to the Mode integration and Hub severance, was $0.40.
Now I'll discuss details for the quarter, starting with the financial performance of the Hub segment. The Hub segment generated revenue of $596 million, which is a 6% increase over last year. Taking a closer look at Hub's business lines. Intermodal revenue increased 9%. This change includes a 9% volume increase. Price increases were offset by lower fuel and mix. About 1/4 of the volume increase came from fleet boxes sold to Mode agents. Our fastest-growing customer segments were transportation, which was up 17%; and retail and consumer products, which were both up 9%.
Truck brokerage revenue was down 11% on a 7% shorter length of haul, 1% lower volume and lower fuel. The turnaround in truck brokerage was not as quick as we anticipated, and Dave will discuss that in more detail. Logistics revenue was 13% higher than last year.
Hub's gross margin increased by $2.2 million, due primarily to growth in intermodal gross margin. Intermodal margin is up because of volume growth, price increases, turning our containers a little quicker and our focus on doing more of our own drayage. Logistics gross margin was about -- up about $0.5 million, while truck brokerage margin was down by $800,000.
Hub's gross margin as a percentage of sales was 10.9%. This margin percentage is the same as the first quarter of 2012, and it's down 30 basis points compared to last year's 11.2% margin. It's down because of the continued decline in the logistics gross margin percentage and a slight decline in intermodal yield. We expect Hub's gross margin percent to improve the second half of the year.
Hub's costs and expenses were flat at $40 million compared to last year. Costs and expenses are $1.7 million lower than the first quarter of 2012. The majority of this decrease relates to lower bonuses. A large portion of the bonus fluctuates depending on EPS for the year. Given the challenging economic environment and the fact that the turnaround in truck brokerage is not happening as quickly as we'd hoped, bonus expense is $1.3 million lower than it was in the first quarter of 2012. Finally, operating income for the Hub segment increased $2.3 million or 10%.
Now I'll discuss results for the Mode segment. Mode's revenue was $194 million. The revenue breakdown is $86 million in intermodal; $81 million in truck brokerage; and $27 million in logistics. Mode's business was relatively flat compared to last year across all 3 business lines. Mode's gross margin increased $400,000 over last year due to yield improvement in all 3 service lines. Gross margin as a percentage of sales was 11.6% compared to 11.5% last year.
Mode's total cost and expenses decreased $1.2 million compared to last year. Mode had $350,000 of onetime costs in 2011 related to the integration. Salaries and employee benefits decreased $800,000, in line with our cost reduction plan. Operating margin for Mode was 1.5%, which is up from last quarter's 1.4% operating margin.
Turning to our headcount. We had 1,362 employees, excluding drivers, at the end of June. That's up 6 people compared to the end of March.
Now I'll discuss 2012 full year earnings guidance. We estimate that our diluted earnings per share will be between $1.80 and $1.90 for 2012. We think we'll have 37,200,000 weighted average diluted shares. The key drivers for this lower guidance includes lower truck brokerage improvement and a soft market. We think that our quarterly costs and expenses will range between $60 million and $63 million for the rest of 2012.
Turning now to our balance sheet and how we used our cash. We ended the quarter with $52 million in cash and no debt. During the quarter, we spent $4 million on capital expenditures. We think we'll spend between $60 million and $70 million on capital expenditures in 2012. Between $20 million and $30 million is for our new corporate headquarters, which is a 2-year project. $26 million is for containers, and most of the remainder is for technology investment.
To wrap it up for the financial section, we're proud of our record quarter, and we're focused on the levers that will maximize our profit.
And now you'll hear from our CEO, Dave Yeager.
