Thank you, Chris. Good afternoon, and thank you for joining us today. Joining me in Chicago is Tim Romenesko, our President and Chief Operating Officer; and Mike Sharp, our Interim Chief Financial Officer.
We have a good second quarter to report today. We've executed well, continued to integrate our Aviation Services platform and made ongoing operational progress in a number of key areas.
To begin, I'd like to give you some of the financial highlights from the second quarter. Revenues in the quarter were $513 million, up 6.4% versus the prior year. Our revenue mix shifted towards the higher growth commercial markets, which now comprise 60% of second quarter sales, with government and defense now comprising 40%.
Aviation Services revenues were up 4% with a number of areas showing improvement, including our airframe maintenance centers, aftermarket parts support businesses and improved operating performance from our Airlift business. Sales in the segment were negatively impacted by a reduction in program activity at our Defense Logistics business, which we had expected.
Technology Products revenue grew by 16% versus prior year, driven by acquisition-related growth. This was partially offset, as expected, by pressure in Mobility Systems, which saw a $39 million sales decline on year-over-year basis and a $33 million sales decline on a sequential basis.
Consolidated gross profit margin improved to 17% from 16.3% in the year-ago quarter. Aviation Services gross margin increased slightly from 17% the prior year to 17.2% this year. Technology Products gross margin improved to 16.4% versus last year's margin of 13.8%. There are a few moving pieces, but the key items were higher gross margins associated with our acquired businesses and reduced margins in Mobility Products.
Total operating profit in the second quarter was up 10.2% to $38 million, and operating margin of 7.4%, up versus last year's margin of 7.1%. We made good profitability gains in many areas, but as previously mentioned, we also absorbed a significant reduction from our Mobility Systems business.
Net income was up slightly from a year ago at $17.8 million in the quarter and diluted EPS was $0.44, which exceeded both our internal and consensus expectations.
In summary, we're pleased with the final -- financial performance in the second quarter, which followed a good first quarter. We remain confident in our full year view of the business, and we've raised our earnings guidance for the full year. We continue to feel particularly good about our commercial aerospace business and our position. Our strength versus last year was driven by steady demand under new and existing contracts and customers, including business with Delta, Southwest, United and Air Canada. Our MRO business has benefited from our ability to execute. We've also seen a reduction in total industry MRO capacity in North America, which is a positive development. And we are benefiting from aircraft movement, which opens up opportunities for both our MRO and parts support businesses.
With respect to the defense markets, we see 2 different factors. For our Aviation Services segment, we see potential opportunity as the geopolitical environment demands a high level of readiness be maintained while many existing platforms are aging and budgets are constrained. Our Aviation Services business enables government and defense customers to do more with less and to reduce their cost. This includes our MRO, supply chain and airlift activities. We believe our market position provides an opportunity to be part of our customers' solution in this very challenging budget environment. At the same time, we do have exposure, as you see with our mobility business. In general, we're managing through the environment well and were able to absorb the revenue decline in defense while increasing our earnings per share.
As you know, we've consolidated 3 segments into one newly created Aviation Services platform. This reflects our managing this set of businesses as we look to drive operating efficiencies while providing our customers with more comprehensive solutions and attempting to give ourselves a competitive advantage. We believe this will create additional growth opportunities and lead to margin improvement. A good example of this is the recent contract we have entered into for the sale of 2 aircraft to the Colombian Air Force, which we expect to deliver in the second half of our fiscal year. We created a comprehensive solution for this new customer by bringing together capabilities in 8 different areas of our business.
Also during the quarter, we announced the sale of 10 aircraft to MAS from our joint venture portfolio. This will reduce our aircraft leased portfolio to 8 aircraft, consistent with our stated goal to reduce our investment in aircraft leasing. We expect to further reduce our leased portfolio by 2 aircraft during the third quarter. While we have reduced our portfolio of leased aircraft, we will remain active in the aircraft sales and remarketing business, where we have established -- where we have an established market presence and a successful track record and where such activity helps connect many pieces of our organization to deliver solutions for our customers.
In our Technology Products segment, our strategy is to build around the leadership positions we have established in the niches we operate, both in Cargo Systems and Mobility Products. In both of these businesses, we are close to the customer, either prime into DoD or Tier 1 into Boeing and Airbus. It's also key that we have a proprietary product and own the intellectual property. As we look to grow our Technology Products segment, we will focus on finding niche markets where we can add value to our customers in design; engineering; integration; and most importantly, aftermarket support. Our Technology Products business is generally healthy. The Telair and Nordisk additions are performing well. However, over the next couple of quarters, we'll continue to face tough year-over-year comparisons in this segment due to the reduction in sales volume in our mobility business.
At this point, I'd like to turn the call over to Mike for a more detailed review of our financial performance in the quarter and the specifics on the guidance we're providing to you.
