Thanks, Pete, and good morning. Let's turn to Slide 8. So it seems that our first quarter results demonstrated good progress on the past profitability. Turning to the consolidated income statement, we posted a gross profit of $2.2 million for the quarter or a 4.8% gross margin excluding restructuring expenses. This is up from last year's full year rate, reflecting the progress at Gearing. The gross margin was below the 2011 first quarter figure only because of the impact of the high steel content on Towers left versus last year. At last year's Towers, they've been built including steel, we estimate that the gross profit margin would have been comparable. And sequentially versus the fourth quarter of 2011, gross margin was up nearly 3 percentage points.
We continue to make progress with producing operating expenses as well. At $6.2 million first quarter expenses, were down $400,000 from last year due to lower salary investment expense and reduced professional expenses. These reductions more than offset $75,000 of restructuring expenses, mainly incurred to close a west coast service office. As a percent of sales, excluding restructuring, operating expenses totaled 11.2%, down both sequentially and year-to-year. We are on track for the $25 million to $26 million full year run rate we projected, which reflects benefits from a portion of restructuring actions already completed, notably the closing of the European office and some other overhead reduction.
Our operating loss was $3.9 million, including $500,000 of restructuring expense. The operational improvement is more evident in the adjusted EBITDA of $1.4 million, which did not include non-cash charges or restructuring. The loss per share narrowed to $0.03. We continue to report no income tax credit on the operating line. At the end of last year, we had more than $136 million of tax loss carry forward. When the company turns profitable, we will operate for some time without making federal income tax payments.
On the next Slide, Towers and Weldments recorded revenue of $35.2 million, and up from 2011, but the true activity in terms of Tower sections produced was actually down 19% from last year. Just to remind you, referring to the illustration in the bottom right-hand corner of the slide, materials, mainly steel, account for about 2/3 of the cost of the tower. Some customers prefer to procure and provide the steel themselves. When this happens, our reported revenue dollars are lower, and therefore, our reported margins appear higher on the lower revenue base.
During Q1 of 2011, we had a large share of fabrication-only towers, about 43% of the total towers sold but none in 2012. We are gaining traction with our diversification into weldments. In the first quarter of 2012 versus 2011, weldment revenue tripled to $1.8 million or about 5% of the Towers segment revenue. However, incremental margins on weldments are about double those from wind towers, therefore our implication for towers is closer to 10%. We expect to ship about $10 million of heavy weldments this year and have set a goal of doubling that level in 2013. So gradually, we will achieve more diversification in our customer and industry base for these plants.
In our Abilene plant today, drill crawler masks for mining and wind towers are now being produced in adjacent production line, a tribute to our increasingly flexible manufacturing capabilities.
Operating income and EBITDA were below the prior year due to the 19% volume reduction in towers and a lower margin mix of towers due to increased pricing pressures, partly offsetting were the benefits of increased sales of weldments and improved productivity.
On the next slide, Gearing, our first quarter revenue rose to $16 million, up 18% from the prior year. As you'll see in the bottom right-hand corner graph, the composition of our revenue continues the recent trend line shifting out of Gearing, going as new wind turbines and into a broader range of industries. As the green line shows, just the first quarter of 2010, 2 years ago, sales for industrial customers have nearly quadrupled from about $3 million a quarter to more than $12 million in the current quarter. And our sales force continues to identify additional opportunities for growth. In this quarter, Gearing earned $1.8 million of EBITDA and the adjusted EBITDA margin rose to more than 11%, a significant improvement from last year's run rate. The higher margins of the current customer mix are showing through and the difficulties associated with the customer transition are beginning to be behind us. During the next several quarters, we expect it to continue to perform with low double-digit margins while we manage the distractions of the plant consolidation and see only the limited benefits from restructuring. As we move into 2013, however, we should increasingly benefit from the consolidation. Our medium-term goal is to expand our EBITDA margins to industry average levels in the 20% range.
Our Services business made progress in the first quarter on the next slide, which is seasonally the lowest. We booked revenue of $3.4 million, nearly double the prior year. The operating loss rose to $1.6 million due to nearly $300,000 of higher depreciation expense. This increase was due to the startup of the drivetrain repair center late in the first quarter last year. The EBITDA loss improved modestly, however, due to the higher activity level. We remain very focused on improving this business by growing sales, implementing better systems, introducing higher margin proprietary service offerings and managing our costs. Our target is to approach breakeven EBITDA in the second quarter and then begin generating positive cash flow in the second half of the year.
The graph on the next slide shows the band within which we expect our operating working capital to range given the structure of our business, anywhere between 6% and 12% of sales, depending on mix and timing of customer deposits. Our operating working capital rose to 7.4% of trailing 3-month annualized sales in the first quarter. We built $9 million of inventory, mainly for raw materials to support a higher tower build level in the second quarter. In addition to higher inventories, customer deposits declined as expected. These effects were largely offset by higher payables. Net total operating working capital rose $2 million in the quarter to $16 million.
On Slide 11, liquidity. We finished the quarter with $11.3 million of cash and short-term investments, about $3 million down from the prior year end. We used cash to fund the increased working capital and to pay down debt. Debt and capital lease balances declined to $13.1 million and include $2.7 million of grants or forgivable loans, which are costs in this debt that don't really require repayment. So without that amount, our total debt and capitalized lease balance was $10.4 million.
At the end of the quarter, as planned, we increased our usage of the Wells Fargo line to $2.9 million with $7.1 million available. With heavy tower builds through the second quarter, we will likely increase working capital and usage on the Wells line.
The next slide shows the summation between debt and EBITDA. As I just mentioned, the debt balance declined further in the quarter and the TTM EBITDA turned up due to the relatively stronger Q1 results. With approximately another $3.3 million scheduled for repayment this year, we are in discussions to increase our lease financing by $5 million to $10 million on our sizable unencumbered fixed asset base to improve financial flexibility. Even with this additional financing, after scheduled debt repayment once we completed the sale of the Brandon facility and pay off the associated mortgage, our year-end's debt balance would not likely exceed $15 million.
And on the final slide, we have not changed our outlook for the year. We are forecasting revenue growth of nearly 20% and gross margin expansion of between 2 and 3.5 percentage points. In Towers, our challenge is to efficiently manage the production changeovers associated with the large new customers we added last year. In Gearing, we are seeing higher margins in our backlog as our improved operating performance and expanded customer base are allowing us to improve our pricing modestly. And in Services, where our activity level's building, we're managing our tech utilization better.
Second quarter revenues and EBITDA should improve sequentially and be significantly above the prior year. And we are still looking at full year adjusted EBITDA in the range of $8 million to $10 million.
This completes our prepared remarks. And now I'll turn it over to Pete to handle questions.
