Thanks, Henning, and good morning. I'll start by discussing Gibraltar's P&L results, and the P&L information in this presentation represents adjusted measures for continuing operations and our reconciled supplemental schedule's in the earnings press release.
So let's turn to Slide #7 in the presentation and sequential performance. Revenues were up 14% from the first quarter. This growth was predominately organic and driven by seasonal volume increases in every market we serve, with the only exception being Europe, where we derived approximately 6% of our consolidated revenues. And each of our major residential product categories had double-digit increases compared to Q1.
Adjusted operating income nearly doubled sequentially, driven by the leverage on the higher organic volume, and this improvement included our acquisition of the D.S. Brown Company, which turned in a record quarter for revenue and profitability, as Henning noted. And regarding adjusted EPS, the sequential increase of $0.19 per diluted share was driven by operating income growth, as well as a small benefit from a discrete income tax item.
Now let's turn to Slide #8 entitled Year-Over-Year Performance. This slide includes year-over-year comparisons for the second quarter, and as well, the first 6 months of 2012. I'll begin by going down the 3-month columns. Revenue grew 5% for the quarter, largely driven by 3% higher organic sales volume, primarily in the nonresidential and industrial end markets, and 2% of the growth came from acquisitions of Award Metals and Edvan.
Adjusted operating income was down 16% for the 3-month period, and operating margin was down 200 basis points. The net effect of gross margin squeezed [ph] 360 basis points, while SG&A expense as a percent of revenue was lower by 160 basis points. Approximately half the gross margin decline was driven by competitive end market conditions and less favorable material margin; and the other half from West Coast integration efforts, including a related inventory charge of $2.2 million.
The improved SG&A expense as a percent of revenue came from lower compensation expenses, including lower equity comp. Translating these factors into their effect on adjusted EPS, the bridge from last year's Q2 adjusted EPS of $0.30 to this year's second quarter EPS is summarized as follows: a $0.04 per share increase from leveraging the higher organic growth, driven mainly by sales of infrastructure products and grating and expanded metals product in the nonresidential industrial markets; a $0.03 per share increase from the lower SG&A expenses; and a $0.03 improvement came from a lower effective income tax rate. These increases were offset by a $0.06 per share decrease related to the cost of integrating the West Coast operations, and $0.04 of the $0.06 was the inventory write-down and a combined $0.06 per share decrease related to the narrowed spread between raw material costs and pricing.
Now going down the 6-month columns. Revenue grew 11% for the half, half year. This growth was largely driven by the 3 acquisitions, the first of which came in early April 2011. The 3 acquired businesses added $26 billion or 7% to revenue for the first half this year. The organic increase amounted to a 4% increase and came equally from residential and nonresidential markets, and largely, volume growth.
Adjusted operating income was down 12% for the 6-month period, and the operating margin was down 170 basis points, matching the gross margin decrease of 170 basis points, while SG&A expense as a percent of revenue remained unchanged. A large majority of the gross margin decline resulted from the cost of the West Coast integration effort, including the inventory charge of $2.2 million, and we expect the largest portions of the integration costs have been incurred.
Translating these factors into the effect on adjusted EPS, the bridge from last year's $0.41 for the first half to this year's first half is summarized as follows: a 9% -- or I'm sorry, a $0.09 per share increase from the combined contribution of organic growth and incremental effect of the acquisitions led by D.S. Brown; a $0.03 improvement came from the lower income tax rate; and these positives were offset by an $0.11 share -- per share decrease related to the cost of integrating our West Coast operations; and a combined $0.05 per share decrease predominately related to the narrowed spread on material costs and customer pricing.
And regarding free cash flow, the amounts shown on Slide 8 reflect our historical pattern of a seasonal investment and working capital in the first quarters followed in the second quarter's with converting a portion of that back into cash.
Turning to Slide #9, titled Net Income and EPS. I've already described the changes in operating income, so my remarks on this page and this slide regard interest expense and income taxes. Interest expense was higher in the Q2 of 2011 due to funds borrowed under our revolving credit facility to help finance the acquisitions of D.S. Brown and Award Metals last year compared to no amounts outstanding on our revolver during the second quarter of 2012. Interest expense for the half year decreased, a net result of higher borrowings on the revolver last year, as well as interest income earned last year on a note receivable from a 2008 divestiture.
Regarding income taxes, we recognized a much lower effective tax rate for both the quarter and half year of 2012. The 34% rate for Q2 2012 compares favorably to the 42% rate in Q2 last year due to a 5 percentage point reduction on the reversal of an uncertain tax position after the recent completion of a tax audit, plus lower nondeductible expenses this quarter. The 6-month 2012 rate of 35% was lower than the 43% a year ago for the same reasons.
Now turning to Slide #9, titled Continued Low Net Debt. We ended the second quarter with an increase in cash compared to March end, having converted some of our seasonal investment and working capital. We also continued to have positions of loan debt to capitalization and net debt to net capitalization. We've not had borrowings against our revolver since mid-September 2011. We continue to have a conservative debt level and no near-term debt maturities. Our leverage ratio at the end of June was 3.1x and our liquidity increased again to $194 million at the end of June. With a strong balance sheet, lower leverage and ample liquidity, we're strongly positioned to finance organic and acquisition-driven growth opportunities going forward.
I'll conclude with comments on our updated P&L expectations for 2012. As both Brian and Henning stated earlier, the growth we've seen in our end markets is somewhat slower than we anticipated going into the year. The market indices and published reports of various industry observers underscore a mixed outlook. For example, the National Association of Homebuilders report, in their housing market index for July stated that while builder confidence is improving, housing is still in a fragile state of recovery. In the American Institute of Architects' Architecture Billings Index dropped for the third consecutive month to 45 in May and essentially at that same level for June, foreshadowing softer demand in the multifamily institutional markets and flat design in construction activity in the commercial and industrial markets. And as you know, the recent report on second quarter GDP growth in the U.S. fell to 1.5%. These and other published reports plus our own order rates thus far in Q3 suggest that our organic growth for the second half may slow a bit and yield an approximate 2% organic growth rate for the full year 2012.
Our expectation for the third quarter of 2012 compared to Q3 2011 is for comparable adjusted earnings per share on modestly lower revenue, with an improved operating margin led by lower West Coast restructuring cost. And for the fourth quarter of 2012, which is a seasonally low quarter for revenue, earnings showed improved compared to Q4 2011 based on improved efficiency in our West Coast operations plus much lower SG&A expense.
For the full year 2012 P&L, we now expect organic revenue growth approximating 2% for our core businesses plus additional revenue from the acquisitions, which could be an incremental $30 million. We expect our gross margin for the full year 2012 to approximate 20% based on our current assumption of slower volume growth in the second half and lower volatility and raw material costs. It also includes shrinking cost for the completion of our West Coast region reorganization.
Regarding our SG&A expense for the full year 2012, we expect it to approximate $27 million per quarter and represent about 13% of our full year revenues. Our other expectations for financial measures for continuing operations on an adjusted basis for the full year 2012 include net interest expense at a current run rate of $4.7 million to $4.8 million per quarter, an effective tax rate of 37%, CapEx spending of approximately $15 million to $16 million and free cash flow to approximate 4% of full year revenues.
In summary, despite second half economic conditions that appear to be softening in key end markets, we expect full year EPS improvement over 2011. And now Brian has concluding remarks.
