Thanks, Dan. Good morning, everyone. As Dan has previously noted, we had a very solid third quarter. Our revenue for the quarter was up nearly 27% from the comparable period of 2011. Revenue growth was driven by several factors, including the efficient -- or the effective -- the effective addition of hotels we acquired since third quarter 2011. The acquisitions as a group have met our first year revenue expectations. In addition, we rebranded 10 hotels over the past year. These hotels, as a group, have RevPAR growth ahead of the pace required to replace the lost EBITDA from the rebranding. Although the RevPAR growth from rebranding was exceptional, the 10 hotels amount to less than 10% of our overall revenue.
We also completed major renovations at 11 of our hotels in the past year. This group of renovated hotels has met or exceeded our RevPAR expectations. Our portfolio has also benefited as general market conditions continue to improve and our operational team continues to focus hotel by hotel on revenue management.
As Dan previously noted, we saw substantial pro forma RevPAR growth in the quarter. Q3 pro forma RevPAR growth was 11.6% as compared from the same quarter in 2011. This marks the second straight quarter of double-digit pro forma RevPAR growth for our company. Further, our pro forma RevPAR growth compares favorably with the U.S. hotel industry's 5.1% growth for the quarter.
We're also pleased with the mix of ADR and occupancy realized in the quarter. ADR for the quarter was $97.72, an increase of 5.6% over the comparable period in 2011. Q3 occupancy was 73.9%, an increase of 5.7% over the comparable period in 2011. Considering the relative muted supply growth anticipated over the near term in many of our markets, we remain bullish about our ability to generate ADR growth.
The revenue growth and mix of occupancy and ADR previously -- or positively affected the adjusted EBITDA performance of our company as well. In the quarter, we generated adjusted EBITDA of $15.2 million, which is an increase of nearly 26% quarter-over-quarter. The growth in EBITDA was driven by several factors previously discussed: the recent acquisitions, the successful rebranding, renovations, the mix of occupancy and ADR at our hotels and our focused expense control.
On a hotel basis, we realized pro forma Hotel EBITDA of $17.4 million for the quarter. When calculated as a percent of revenue, pro forma Hotel EBITDA margin for the quarter was 33.9%. When comparing margins quarter-over-quarter, we realized margin expansion of 261 basis points in the third quarter.
Regarding capital markets, we recently were able to both strengthen our balance sheet and expand credit capacity to allow us to further execute on our stated strategy of acquiring additional hotels with best brands in best markets. On October 3, we closed on our initial follow-on public offering, raising 12 million shares of common stock, an increase of 20% over the previously announced offering size of 10 million shares, at a price of $8.15 per share. The underwriters of the offering fully exercised their option to purchase an additional 1.8 million shares. The total number of shares, including the option shares, was 13.8 million shares. Total net proceeds of approximately $1.7 million were realized after deducting the underwriting discount and other estimated offering expenses.
On November 6, 2012, we have closed on expansion of our senior secured revolving credit facility. We increased our credit facility by $25 million to $150 million, with the ability to accordion the line up to $200 million. As of November 6, we have approximately $70 million outstanding on the line. Current capacity on the line is approximately $114 million. We do have the ability to increase capacity up to $150 million by pledging additional collateral -- hotels as collateral. Currently, we have 15 hotels that are unencumbered and available as collateral.
Regarding hotel renovations, we were not particularly active in the quarter, having invested $5.3 million to do renovations on hotels. Most of the dollars spent were preconstruction dollars on projects that will be completed in the fourth quarter and first quarter of 2013. No RevPAR or EBITDA disruption occurred in third quarter. We do anticipate spending $8 million to $11 million on major renovations to 7 hotels during fourth quarter. For the fourth quarter, we expect RevPAR disruption of approximately 150 basis points, and we anticipate $200,000 of EBITDA disruption from rooms out of service.
Our outlook remains positive for the balance of the year. We are providing guidance for the fourth quarter 2012, and based on positive results year to date, we are increasing guidance for full year 2012. Regarding the fourth quarter outlook, we're expecting RevPAR growth on a pro forma basis to be in the range of 7% to 9%. We're expecting RevPAR growth on a same-store basis to be in the range of 8% to 10%. We are estimating our AFFO on a fully diluted per share basis to be in the range of $0.11 to $0.13. Our AFFO guidance includes our recent follow-on common stock offering, 9 hotels acquired post quarter end, 150 basis points of anticipated RevPAR disruption and $200,000 of EBITDA disruption, resulting from the renovation of 7 of our same-store hotels. It is also anticipated that we will receive an income tax benefit of $0.02 on a fully diluted per share basis for the fourth quarter.
Regarding 2012 full year outlook, we are increasing our anticipated RevPAR growth on a pro forma basis to be in the range of 7% to 9%. And on our same store, we expect an 8% to 10% growth.
We are increasing the lower end of our AFFO guidance. Our new AFFO range on a fully diluted per share basis is now $0.78 to $0.80, amended from the previous guidance of $0.77 to $0.80. Our updated AFFO guidance includes our recent follow-on -- our common stock offering, 9 hotels acquired post quarter end, 150 basis points of anticipated RevPAR disruption and the $200,000 EBITDA disruption resulting from renovations at our 7 same-store hotels.
It is also anticipated that we will receive an income tax benefit of $0.02 on a fully per share diluted basis for the full year.
