Operator

Ladies and gentlemen, thank you for standing by and welcome to the SBA Second Quarter Results Call. [Operator Instructions] As a reminder, this conference is being recorded.

And I would now like to turn the conference over to our host, Mark DeRussy, Vice President of Finance. Please go ahead.

Mark DeRussy -- Vice President, Finance

Thanks, Caroline. Good evening everyone and thank you for joining us for SBA's second quarter 2021 earnings conference call. Here with me today are Jeff Stoops, our President and Chief Executive Officer; and Brendan Cavanagh, our Chief Financial Officer.

So, the information we will discuss on this call is forward-looking, including, but not limited to, any guidance for 2021 and beyond. In today's press release and in our SEC filings, we detail material risks that may cause our future results to differ from our expectations.

Our statements are as of today, August 2, and we have no obligation to update any forward-looking statements we may make. In addition, our comments will include non-GAAP financial measures and other key operating metrics. The reconciliation of and other information regarding these items can be found in our supplemental financial data package, which is located on the landing page of our Investor Relations website.

And with that, I will now turn the call over to Brendan.

Brendan T. Cavanagh -- Executive Vice President and Chief Financial Officer

Thanks, Mark. Good evening. SBA had a tremendous quarter with results for the second quarter ahead of our expectations in most key areas. Total GAAP site leasing revenues for the second quarter were $524.1 million and cash site leasing revenues were $514.6 million. Foreign exchange rates were ahead of our previously forecasted FX rate estimates for the quarter, contributing $3.1 million of incremental site leasing revenue in the second quarter. They were also a tailwind on comparisons to the second quarter of 2020, positively impacting revenues by $3.5 million on a year-over-year basis.

Same tower recurring cash leasing revenue growth for the second quarter, which is calculated on a constant currency basis, was 3.4% over the second quarter of 2020, including the impact of 2.5% of churn. On a gross basis, same tower growth was 5.9%.

Domestic same tower recurring cash leasing revenue growth over the second quarter of last year was 5.5% on a gross basis and 3% on a net basis, including 2.5% of churn. Domestic operational leasing activity or bookings, representing new revenue placed under contract during the second quarter, was up significantly from the prior quarter and represented the highest quarterly level since 2014. Even with this high level of executions, our domestic new lease and new amendment application backlog finished the quarter at a multi-year high. These backlog support our expectations for continued strong domestic operational leasing activity throughout the balance of this year.

During the second quarter, amendment activity represented 34% of our domestic bookings with 66% coming from new leases, the first time in many years the bookings from new leases outpaced that from amendment. The Big 4 carriers of AT&T, T-Mobile, Verizon and DISH represented 97% of total incremental domestic leasing revenue signed up during the quarter. Internationally, on a constant currency basis, same tower cash leasing revenue growth was 5.3% net, including 2.2% of churn or 7.5% on a gross basis.

International leasing activity increased modestly from the first quarter. In Brazil, our largest international market, we had an improved quarter of leasing activity. Gross same tower organic growth in Brazil was 8.9% on a constant currency basis. During the second quarter, 84.8% of consolidated cash site leasing revenue was denominated in US dollars.

The majority of non-US dollar denominated revenue was from Brazil with Brazil representing 11.5% of consolidated cash site leasing revenues during the quarter and 8.4% of cash site leasing revenue excluding revenues from pass through expenses. So, our cash flow for the second quarter was $421.2 million.

Our tower cash flow margins continue to be very strong with the second quarter Domestic tower cash flow margin of 84.7% and an international tower cash flow margin of 70.8% or 91%, excluding the impact of pass-through reimbursable expenses.

Adjusted EBITDA in the second quarter was $400.2 million. The adjusted EBITDA margin was 70.7% in the quarter. Excluding the impact of revenues from pass-through expenses, adjusted EBITDA margin was 75%. Approximately 98% of our total adjusted EBITDA was attributable to our tower leasing business in the second quarter. During the second quarter, our services business produced record results for the company with $51.4 million in revenue and over $11 million of segment operating profit.

The very high activity levels we saw in the first quarter strengthened further in the second quarter, resulting in a quarter end services backlog that was 30% above first quarter levels and was also the highest in our company's history. We expect to see continued high levels of services activity throughout the rest of the year and as a result have increased our full-year outlook for site development revenue by $25 million from last quarter and by $40 million from our initial outlook.

AFFO in the second quarter was $293.5 million. AFFO per share was $2.64, an increase of 15.3% over the second quarter of 2020. During the second quarter, we continued to expand our portfolio acquiring 57 communication sites for a total cash consideration of $67 million. We also built 98 new sites in the quarter. Subsequent to quarter end, we have purchased or agreed to purchase approximately 400 additional sites in our existing markets for an aggregate price of $95 million. And we anticipate closing on the majority of the sites under contract by the end of the year.

In addition, during the second quarter, we announced that through a new joint venture arrangement, we have entered into a contract with Airtel Tanzania, a subsidiary of Airtel Africa, to purchase their approximately 1,400 towers in Tanzania. Under this agreement, Airtel will leaseback space on each of the towers and we'll also provide a fixed minimum number of build-to-suit towers during the first five years following the closing of the acquisition. The total purchase price for the acquisition is expected to be approximately $175 million and the acquisition is anticipated to close in stages starting in the fourth quarter.

For our updated 2021 outlook, we have assumed that the acquisition closes at the end of the year. And thus, we have included the entire purchase price in our outlook for discretionary capital expenditures. But we have included no revenue or tower cash flow associated with these events. We expect the assets to produce approximately $80 million of adjusted EBITDA during the first full year of operations under the joint venture. SBA will be the majority partner for joint venture and we are partnering with Paradigm Infrastructure Limited, a UK company founded by former senior executives of American Tower, which is focused on developing, owning and operating shared passive wireless infrastructure in selected growth markets.

We believe the combined international tower industry operating experience of SBA and Paradigm will allow us to maximize the opportunity in this new rapidly growing market. In addition to do tower assets, we also continue to invest in the land under our sites. During the quarter, we spent an aggregate of $11.8 million to buy land and easements and to extend ground lease terms.

At the end of the quarter, we owned or controlled for more than 20 years the land underneath approximately 71% of our towers. And the average remaining life under our ground leases, including renewal options under our control, is approximately 37 years.

In this afternoon's earnings press release, we included our updated outlook for full year '21. Our update increased expectations for site leasing revenue, site development revenue, adjusted EBITDA, AFFO and AFFO per share. These increases are driven by outperformance across our business, increased network investment activities by our customers, improved foreign exchange rates, reduced non-discretionary cash capital expenditures and reduced cash interest expense as a result of timely refinancings.

Notwithstanding our strong domestic leasing bookings during the second quarter, which were ahead of our expectations, we have not increased our 2021 outlook for incremental organic domestic leasing revenue. New bookings typically begin to accrue revenue at the earlier of a date-certain or commencement of construction. For outlook purposes, unless we have received notice of construction commencement, we only consider the date certain, which for the second quarter bookings to outperformance generally ranges from late in the fourth quarter sometime in the first half of 2022.

As we mentioned last quarter, we anticipate our reported gross domestic same tower revenue growth will begin to increase in the second half of the year and that we will exit 2021 at the highest rate of the year. As is always the case, our full year 2021 outlook does not assume any further acquisitions beyond those under contract today. And the outlook also does not assume any share repurchases other than those completed as of today. However, when opportunities present, we are likely to invest in additional assets or share repurchases or both during the rest of the year.

Our outlook for net cash interest expense did not contemplate any further financing activity in 2021. Finally, our outlook for AFFO per share is based on an assumed weighted average number of diluted common shares of 111.5 million, which assumption is influenced in part by estimated future share prices.

With that, I will now turn things over to Mark, who will provide an update on our liquidity position and balance sheet.

Mark DeRussy -- Vice President, Finance

Thanks, Brendan. We ended the quarter with $12 billion of total debt and $11.7 billion of net debt. Our net debt to annualized adjusted EBITDA leverage ratio was 7.3 times, a return to our target range of 77.5 times, faster than originally anticipated after the PG&E acquisition during the first quarter.

Our second quarter net cash interest coverage ratio of adjusted EBITDA to net cash interest expense was 4.4 times. On May 14, the company through an existing trust issued $1.165 billion of Secured Tower Revenue Securities, Series 21-1C, which have an anticipated repayment date of November 9, 2026 and a final maturity date of May 9, 2051.

These securities have a fixed annual interest rate of 1.631% payable monthly. The net proceeds from this offering were used to repay the entire aggregate principal amount of the 2017-1C Tower Securities and for general corporate purposes. Then on July 7, the company amended its existing revolving credit facility. Among other things, this amendment increased the total commitments under the facility from $1.25 billion to $1.5 billion.

In addition, extended the maturity date of the facility to July 7, 2026, lowered the applicable interest rate margins and commitment fees out of the facility and incorporated sustainability linked targets into the facility, allowing for interest rate and commitment fee adjustments based on how we perform against those targets. We are pleased to be one of the first companies to include such sustainability focused provisions in our credit facility.

As of today, we have no amounts outstanding under our revolver and the weighted average interest rate of our outstanding debt is 2.9% with a weighted average maturity of approximately 4.5 years. During the second quarter, we did not purchase any shares of our common stock. As of today, we have $475.1 million of repurchase authorization remaining under our $1 billion stock repurchase plan. The company's shares outstanding at June 30, 2021 were 109.5 million compared to 111.9 million at June 30, 2020, a reduction of 2.1%.

In addition, during the second quarter, we declared and paid a cash dividend of $63.5 million or $0.58 per share. And today, we announced that our Board of Directors declared a third quarter dividend of $0.58 per share, which is payable on September 23, 2021 to shareholders of record as of the close of business on August 26, 2021. Today's dividend announcement represents a payout ratio of 22% of second quarter AFFO per share, which leaves us ample room for material future dividend growth.

And with that, I will now turn the call over to Jeff.

Jeffrey A. Stoops -- Director, President and Chief Executive Officer

Thanks, Mark. And good evening, everyone. As you have heard, we had a very strong performance in the second quarter, one of our best in quite some time. Domestically, our customers were extremely active. This quarter, we signed up more leasing revenue than we have in any quarter in seven years. We believe the second quarter was the start of a multi-year increase in US wireless carrier capex.

Our backlogs of lease and amendment applications ended up near record highs at the end of the quarter, notwithstanding the high levels of bookings, which obviously bodes well for activity levels throughout the rest of the year and into next. Our customers are focused on building out their 5G networks with a particular focus on upgrading their macro networks. Leasing activity levels were driven by initial C-band initiatives, 2.5-gigahertz deployments, FirstNet amendments, general coverage expansion and the beginning of DISH's network build out. These initiatives also drove our services volumes to record highs.

Last quarter, I was pleased to discuss how our first quarter services results were the best in seven years, but that didn't last long as we reported 18% more services revenue in the second quarter than we did in the first quarter, producing over $51 million of quarterly revenue, the highest in our company's history. We also finished the quarter with the highest services backlog in our history. These results allowed us to increase our full year services outlook by $25 million.

As you could tell, our domestic customers are very busy right now and that sets us up for a very good 2021 and 2022.

Internationally, the second quarter was also very solid for us with quarter-over-quarter sequential increases in new lease and amendment executions and increasing CPI-based escalators in a number of our markets. During the quarter, we signed up 45% of new international revenue through new leases and 55% through amendments to existing leases. Our increased leasing results were driven by our two largest markets, Brazil and South Africa. These markets are still being affected at a greater level than here in the US by the COVID-19 pandemic.

Our local teams though continue to perform very well and we believe we remain well positioned to benefit from increased network investment from our carrier customers as conditions improve and new spectrum auctions take place over the next year, including, for example, the just completed 3.5 gigahertz option in Canada, which raised proceeds well above expectations. Similar auctions of 5G suitable spectrum are planned in the near-term in a number of our markets, including Brazil.

Even with this positive momentum, perhaps the most exciting international news from the quarter was regarding our pending acquisition from Airtel Tanzania. We have partnered with Paradigm Infrastructure for this opportunity. Paradigm was founded by and is run by several former American Tower executives well known to us, including those that were responsible for their initial African expansion and operations. Paradigm will be both the financial investor and an operational partner in this venture.

As a market, Tanzania provides many opportunities. The country has a large growing population and has consistently produced good GDP growth and the new President has indicated a greater commitment to policies that encourage foreign business investment. Despite Tanzania's growth, the mobile penetration rate is still only 41% today, creating significant opportunity for incremental wireless investment and expansion. Wireless market is predominately made up of three major carriers who are relatively well balanced in terms of market share, Vodacom, Airtel and Axian, who recently bought Tigo's operations in Tanzania.

Each of these M&Os are focused on expanding their infrastructure in Tanzania. Airtel will be using a substantial amount of the proceeds from the sale of its sites to increase capex spending. Likewise, Axian is an African-focused and experienced operator whose plans include a strong investment in the country to improve the existing Tigo network. We are purchasing Airtel's approximately 1,400 wireless towers, which have a current tenancy ratio of just under 1.5 tenants per tower, including Airtel and the majority of the existing revenues are denominated in US dollars.

Approximately three quarters of the sites are located on the power grid. And for those that are not required a provision of energy, the costs will be passed through to the tenants. We believe there will be opportunities to not only organically grow our revenues on existing towers but also to expand our tower portfolio in Tanzania, including through a build-to-suit commitment from Airtel over the next five years, which was part of the transaction.

The combination of our partnership with Paradigm, the attractive price paid for the assets and the growth characteristics of the Tanzania market support our belief that this will be a value-creating new market for SBA. In the same way, we have created material value in South Africa and Latin America on a country-specific basis without any requirement for further regional or geographic expansion. We're very excited about this new SBA market.

In addition to our strong second quarter operating results, our balance sheet is in a very strong position. We ended the quarter at 7.3 times net debt to annualized adjusted EBITDA in the middle of our target range of 7 to 7.5 turns, one quarter after absorbing the large first quarter PG&E transaction, demonstrating the ability of our business to rapidly organically delever.

During the quarter we completed a new asset backed financing at the lowest fixed cost interest rate for any non-equity linked security in our history. Shortly after quarter end, we increased the size of all revolving credit facility by $250 million and extended the term. These activities continue to drive our liquidity position higher and our weighted average borrowing costs lower for the first time below 3% to 2.9%.

We have no debt maturities until 2023 and we continue to have access to low cost debt with additional opportunities to continue to improve our overall cost of debt financing. Our liquidity position and balance sheet and our approach with regard to leverage have allowed us to drive incremental AFFO per share and incremental value for our shareholders. We feel really good about our capital structure.

Things are going very well right now here at SBA. Our customers are busy, our financial position is strong and our team members are the best in the industry. We are excited about the opportunities that lay ahead. I want to thank our team members and our customers for their commitment and their contributions to our success. And we look forward to sharing our results with you as we move through the year.

And with that, Caroline, we are ready for questions.

Questions and Answers:

Operator

Thank you. [Operator Instructions] Our first question comes from the line of Ric Prentiss from Raymond James. Your line is open. Please go ahead.

Ric Prentiss -- Raymond James -- Analyst

Hi. Good afternoon, guys.

Jeffrey A. Stoops -- Director, President and Chief Executive Officer

Hi, Ric.

Ric Prentiss -- Raymond James -- Analyst

Hi. A couple of questions. First, obviously PG&E was a big transaction. We saw a story come out the last few weeks that they planned to bury like 10,000 miles of electric line. Is there going to be any changes to the sites you've got where they might be taking electric lines down, making it obviously easier to call on them? And what kind of interest activity have you seen on their sites?

Jeffrey A. Stoops -- Director, President and Chief Executive Officer

We've seen great activity where we're ahead of planned and there's a lot of demand in terms of application backlogs. And in terms of that story, Ric, that relates primarily to the lower wood poles, the ones that are closer to the end user as opposed to the high power transmission poles that are the ones that we really are part of our transaction. So, we don't see a lot of issues related with that. But if in fact there are poles or assets that were part of our transaction, there's a fairly elaborate -- if anything should happen to those in terms of being no longer needed or used by PG&E, there's a fairly complex set of rules that deal with that. So, something that we're -- cover it all and feel very good about, but for the most part, it's going to be the shorter wood poles that they're talking about.

Ric Prentiss -- Raymond James -- Analyst

Makes sense. Okay. Also, the Tanzania joint venture, one of your peers recently doing a big private equity transaction in Europe has started giving consolidated AFFO per share as well as attributable to common AFFO per share. Have you guys considered as now you get a little more joint ventures going that you might move to obviously a EPS stories, they always take out minority interest, but have you thought about moving toward a measure of more proportionate AFFO to common?

Jeffrey A. Stoops -- Director, President and Chief Executive Officer

Brendan?

Brendan T. Cavanagh -- Executive Vice President and Chief Financial Officer

Yeah, Ric. To this point, obviously nothing has been material enough to do that. We do always back out. We've previously identified and we haven't consolidated something obviously the JV piece of the AFFO per share. But it's something we'll look at, if it becomes material, we'll highlight it for you guys. We just haven't had any really to-date.

Ric Prentiss -- Raymond James -- Analyst

Makes sense. Final one, obviously we make that adjustment from AFFO to funds available for distribution. We've been watching, I think, you guys call it amortization of capital contributions, which is still very low. I think it was $13 million in the first half of this year, $33 million all of last year. One of your peers has almost 20 times that level of non-cash items that get put into AFFO. Any thoughts of any changes coming from you that would take it up higher or is it fairly low? Because it's obviously one of the big non-cash items that kind of -- is different between the tower companies?

Jeffrey A. Stoops -- Director, President and Chief Executive Officer

Yeah. I mean, I don't think so, Ric. The things that will drive it up is obviously more augmentation activity, the towers which is certainly possible given the increased amount of activity in general that we're seeing. But the offset to that is that as we have longer terms to our leases, particularly the Verizon MLA which we talked about last quarter and some of the new agreements that come longer-term, that tends to stretch the period over which you're amortizing and actually reduces the amount, plus it's a factor of which towers are getting hit whether work needs to be done at the site, how much it costs, just bring those -- all those kind of things. So I don't expect it to actually move up materially at any point in the next year or two.

Brendan T. Cavanagh -- Executive Vice President and Chief Financial Officer

Yeah. It's very different, Ric, when you're not doing small cell fiber work where it's more common that your customer contributes a large amount of the initial capex upfront. Then you amortize it into that amount. I mean, that's never really been a big issue in the macro tower side of the business other than just the regular augmentation stuff, which is, we don't we don't foresee any material changes in that.

Ric Prentiss -- Raymond James -- Analyst

It makes sense. Obviously I was like going back to cash and the ability to pay dividends. So appreciate that and you guys stay well

Jeffrey A. Stoops -- Director, President and Chief Executive Officer

Thanks. You too.

Operator

Our next question comes from the line of Simon Flannery from Morgan Stanley. Your line is open. Please go ahead.

Simon Flannery -- Morgan Stanley -- Analyst

Great. Thank you very much. I was wondering if you've had any more clarity from T-Mobile about their plans for the Sprint towers. Do you think the churn is going to be consistent with the current contracts or do you think there's the potential to either keep some of those towers or have them pushed out? And any updates on the oil restructuring and how we should think about the impact maybe opening up the potential for more investment in Brazil once that goes through? Thanks.

Jeffrey A. Stoops -- Director, President and Chief Executive Officer

Yeah. In terms of the T-Mobile-Sprint question, Simon, T-Mobile is very organized and very I think ahead of what people thought in terms of their network planning. So there's a lot of crisp communications going back and forth. But I don't know that it materially has changed our prior statements on what we expect in terms of decommissioning. And we don't have any additional news on the uptake of the potential Sprint sites. But I would just say that T-Mobile is very prepared in their work in this area.

Simon Flannery -- Morgan Stanley -- Analyst

Okay.

Jeffrey A. Stoops -- Director, President and Chief Executive Officer

And in terms of the OE [Phonetic], I believe the latest is that we're not expecting anything until at least the fourth quarter of this year, maybe into next. And our prior statements in terms of our exposures to both -- or all three of Tim, Yugo and Clara [Phonetic], those have not changed.

Simon Flannery -- Morgan Stanley -- Analyst

Okay, great. And then, do you think there's an opportunity for you to do more on build-to-suit? I think you did about 100 in the quarter and then it sounds like it's part of the Tanzania story as well. But you haven't done a huge amount relative to what we've been hearing from some of your peers?

Jeffrey A. Stoops -- Director, President and Chief Executive Officer

Yeah. I think there's always an opportunity. The question is, does it represent the terms and the financial returns that we're looking for? I think that the universe of opportunities would allow us to do more.

Simon Flannery -- Morgan Stanley -- Analyst

Great. Thanks a lot.

Operator

Our next question comes from the line of Phil Cusick from JPMorgan. Your line is open. Please go ahead.

Phil Cusick -- JPMorgan -- Analyst

Hey, it's Phil Cusick. Start with the paradigm deal. Was this the team you worked with from South Africa or is this a different team?

Analyst

A-Jeff: No, we didn't work with any of the AMT guys in South Africa, Phil. This is Steve Marshall and Hal Hess and Steve Harris, guys that I've known forever and worked very closely with Steve Marshall at WIA. So that's really just through the industry, this all came together.

Phil Cusick -- JPMorgan -- Analyst

Okay. What's your potential capital commitment over time for this?

Jeffrey A. Stoops -- Director, President and Chief Executive Officer

It's not much beyond the $175 million. I mean, Brendan, what...

Brendan T. Cavanagh -- Executive Vice President and Chief Financial Officer

Yeah, that's the total. Purchase price, $175 million, plus a few incremental costs. So that represents everything. So it wouldn't be materially more than that. I mean, down the road, we'll have to see how things...

Jeffrey A. Stoops -- Director, President and Chief Executive Officer

Yeah. We've -- I mean, we've modeled in some upgrade capex and some refurbishment capex. But you're not talking about material numbers there, Phil.

Phil Cusick -- JPMorgan -- Analyst

Okay. It just sounds like if you're going to do something like this in a whole bunch of new countries, it's -- I would think you'd have a sort of number that you'd be willing to invest alongside them to make these more interesting over time.

Jeffrey A. Stoops -- Director, President and Chief Executive Officer

Yeah. The JV, Phil, is specific to Tanzania. There's no obligation to do anything alongside them going forward. So, there's no commitment as far as that goes.

Phil Cusick -- JPMorgan -- Analyst

Yeah. Okay.

Jeffrey A. Stoops -- Director, President and Chief Executive Officer

If we could find more opportunities like Tanzania, then we'd be excited.

Phil Cusick -- JPMorgan -- Analyst

Got it. Okay. Thanks, guys.

Operator

Our next question comes from the line of Michael Rollins from Citi. Your line is open. Please go ahead.

Michael Rollins -- Citigroup -- Analyst

Thanks and good afternoon. With respect to the domestic leasing activity that you were highlighting just earlier in the call, how does this compare with the internal expectations that you've had? And what does this mean to levels of gross leasing growth that you can achieve in the domestic business over the next couple of years?

And then, just separately, I just wanted to follow-up on another thing that was said earlier. I was just curious if you could unpack why the mix of leasing activity had a greater amount of new sites versus amendments in the domestic business. Thanks.

Jeffrey A. Stoops -- Director, President and Chief Executive Officer

The last one is an easy one to answer, Mike, and it's DISH, because DISH is coming online in the form of entirely new leases and they're very busy. So that's the answer to that. In terms of the second quarter, we achieved results that were ahead of our expectations. We did have some fairly robust expectations but even those were exceeded by the level of second quarter activity. And in terms of the growth rate going forward, I don't want to get too specific other than to say, it's going up.

Michael Rollins -- Citigroup -- Analyst

In the past, I think -- and you can correct me if I don't have this right -- were you talking high-single digits of where you expected gross domestic growth to get over the next few years? I'm just curious if you could just revisit that perspective.

Brendan T. Cavanagh -- Executive Vice President and Chief Financial Officer

Yeah. Mike, from a growth standpoint, we certainly expect it to be mid- to high-single digits in the future given what's going on now. So, when you're talking about going out a lot of years, obviously we're getting bigger and bigger. So you have to add that many more dollars to make that happen. But given the activity levels today, I think as we get a year or so out, you'll start to see us return to levels that are similar to what we've reported in the past when we were busier.

Michael Rollins -- Citigroup -- Analyst

Thanks.

Operator

Our next question comes from the line of Nick Del Deo from MuffettNathanson. Please go ahead. Your line is open.

Nick Del Deo -- MoffettNathanson -- Analyst

Hey. Thanks for taking my questions. First, for the question that Mike just asked, it sounds like DISH was really an outsized contributor to leasing in this quarter. Can you just -- if you back that out, can you talk about how activity from the big three carriers in particular has changed over recent quarters? Was it DISH in particular that really drove the outperformance in leasing versus your expectation or was that drove the outperformance on leasing versus your expectation or was that outperformance more broad based?

Jeffrey A. Stoops -- Director, President and Chief Executive Officer

I would say that the ones that had kind of a step function changes in their levels of activity were DISH and Verizon. And the Verizon story is very understandable, it's coming off the C-band options, their public statements and our MLA with them.

Nick Del Deo -- MoffettNathanson -- Analyst

Okay. Okay, that's helpful. And then one on Tanzania and the partnership with Paradigm. Give an option to eventually buy out their stake or vice versa or is there no mechanism in place to do that?

Jeffrey A. Stoops -- Director, President and Chief Executive Officer

No, there is a mechanism that gives us the right to buy them out.

Nick Del Deo -- MoffettNathanson -- Analyst

Can you talk about the time frame or any other parameters or is that proprietary?

Jeffrey A. Stoops -- Director, President and Chief Executive Officer

It's not that proprietary, it's five years-ish.

Nick Del Deo -- MoffettNathanson -- Analyst

Okay, OK.

Jeffrey A. Stoops -- Director, President and Chief Executive Officer

Might be a reason why it gets accelerated a year, extended a year. But that's generally the time frame that we're looking at.

Nick Del Deo -- MoffettNathanson -- Analyst

Okay. Okay. Good to hear. Thanks, Jeff.

Operator

Our next question comes from the line of Brett Feldman from Goldman Sachs. Your line is open. Please go ahead.

Brett Feldman -- Goldman Sachs -- Analyst

Yeah. Thanks for taking the question. Follow-up a little bit on C-band. Now that you're starting to see what some of the carriers are doing with C-band, how much visibility do you have and to the extent to which that's mostly going to be a significant amendment project versus any visibility into a new site project? Because for all of the operators that you already have a tenant to on C-band, this would be a higher frequency that anything that ever historically used on a macro site. So we would probably that might need densification but I don't know if you have that visibility at this point in time?

And then, just finally for the services backlog. I'm just curious, is all of that services work being done on your towers? Meaning, is it a fairly good leading indicator of what your own leasing [Phonetic] is or you actually winning degree of the business across other portfolios as well? Thanks.

Jeffrey A. Stoops -- Director, President and Chief Executive Officer

The answer to your last question is yes. It is mostly all on our towers, which is why we have the confidence we have. And in terms of your first question, Brad, there will be some subleases in there. But for T-Mobile, Verizon and AT&T, it's going to be mostly amendments and for DISH it's going to be all new leases.

Brett Feldman -- Goldman Sachs -- Analyst

Thank you.

Operator

Our next question comes from the line of Walter Piecyk from LightShed. Your line is open. Please go ahead.

Walter Piecyk -- LightShed -- Analyst

Thanks. Jeff, I'll preface this question by noting that last quarter your average price of your share repurchase was, I think, $258 and the stock is now $340 or $342. But in this quarter, you didn't buy anything. So I'm just kind of curious, is this -- I mean I know this acquisition was whatever $175 million. It's kind of in the ballpark of what you spent last quarter. Is that the connection that we should draw or is it maybe where the stock price is in terms of the activity this quarter?

Jeffrey A. Stoops -- Director, President and Chief Executive Officer

No. We wanted to come down off the 07/06 [Phonetic] and we came down quicker than we thought. And by the time we knew that, we were blacked out.

Walter Piecyk -- LightShed -- Analyst

Got it. And then, on the domestic ramp, when you look at your guidance for new lease activity, it's obviously very high so there's going to be a ramp. Can you give us a sense of Q3 versus Q4? I mean, obviously we're going to have to see some type of jump Q3, but is the bigger jump really going to occur in Q4 in terms of the new lease activity?

Jeffrey A. Stoops -- Director, President and Chief Executive Officer

Yeah. You're talking about the same type of growth rate? Well...

Walter Piecyk -- LightShed -- Analyst

Yeah.

Jeffrey A. Stoops -- Director, President and Chief Executive Officer

You're right, yeah.

Walter Piecyk -- LightShed -- Analyst

Yeah.

Jeffrey A. Stoops -- Director, President and Chief Executive Officer

We expect it to step up sequentially each of the next two quarters. But certainly the fourth quarter would be a bigger step up is our expectation based on the timing of when this stuff we're signing [Speech Overlap].

Walter Piecyk -- LightShed -- Analyst

Orders and stuff came in, yeah. That makes sense. And then, I mean if T-Mobile's got to be a component of that, I mean, it doesn't kind of speak to the timing of how their integration is going, if it's still like more of a Q4 event.

Jeffrey A. Stoops -- Director, President and Chief Executive Officer

Yeah. I mean, they're busy. They're busy and...

Walter Piecyk -- LightShed -- Analyst

But they're not getting activated in Q3, right. It's still not happening until Q4 for them.

Jeffrey A. Stoops -- Director, President and Chief Executive Officer

They're getting stuff activated in Q3 as well. So -- I mean...

Walter Piecyk -- LightShed -- Analyst

Got it. Okay.

Jeffrey A. Stoops -- Director, President and Chief Executive Officer

It's a mixed question. But they're busy in activating stuff, and both -- we expect them in both quarters.

Walter Piecyk -- LightShed -- Analyst

So it's just interesting given it's [Indecipherable] right around the corner for Verizon and they're still kind of back end loaded, but whatever. And then international, that's also a big number. So that's going to be a big ramp second half then for international as well, right? Today, that's $13 million target.

Jeffrey A. Stoops -- Director, President and Chief Executive Officer

It'll be a slight ramp. I don't know if I would call it a big ramp. We can walk to those numbers.

Walter Piecyk -- LightShed -- Analyst

A slight relative to the overall company for sure, but for -- for what your levels have been in the first half of the year, it seems like it's kind of big now.

Jeffrey A. Stoops -- Director, President and Chief Executive Officer

Yeah, it's increasing. I mean, certainly the lease up has been a little bit better just recently. And we expect it to be better as we move through the year. I don't know if I would agree with your characterization now, so we should probably talk about that separately.

Walter Piecyk -- LightShed -- Analyst

Sure. Okay. One last one then, sorry. But T-Mobile's use of DISH's 600-megahertz spectrum. Did that generate an amendment or a collocation or anything?

Jeffrey A. Stoops -- Director, President and Chief Executive Officer

It will when it happens.

Walter Piecyk -- LightShed -- Analyst

Okay. Great. Thank you.

Operator: Our next question comes from the line of Batya Levi from UBS. Please go ahead, your line is open.

Batya Levi -- UBS -- Analyst

Great. Thank you. A couple of follow-ups. First, can you provide some color on the pacing of Sprint churn for this year? I think it was close to $2 million in the first quarter. How do we think about it for the rest of the year and maybe a color if that $30 million still holds for next year? And another question on the services side, the margins are coming in a little bit lighter than historical levels. Is there any opportunity to improve the services margins? And how do we think about the 2022 services revenues? Thank you.

Jeffrey A. Stoops -- Director, President and Chief Executive Officer

Batya, on the Sprint churn piece, it's expected. We had -- I think what we reported last time was about $1.7 million or so in the first quarter. We expect the full year to be somewhere between $8 million -- maybe $8 million to $9 million or so for the year, the fourth quarter impact. And this is again on a full year year-over-year basis will be a little bit bigger because obviously there are some of those leases that are going away as we move through the year.

In terms of next year, right now, we still think the $30 million -- maybe $30 million to $35 million or so is appropriate. I have to hedge a little bit only because the timing of when we get noticed is what they specifically decide to do is a little bit of a fluid situation. But based on what we know today, we -- and lease expiration dates that we think that's a reasonable estimate. Yeah. In terms of the services margins, I mean, our services business is comprised of two distinct offerings, one is site acquisition zoning kind of software and then the second is construction. Construction typically produces about half the margin of the site acq and zoning. So, the mix between site acq, zoning, and construction is what drives the margin. And the margins have actually been based on the type of work being provided historically strong compared to our experience. In terms of next year, I mean, we'll give you next year's guidance when we get there. But there's no reason why the services business because it is primarily on our own tower should materially slow down. It's going to reflect leasing activity.

Batya Levi -- UBS -- Analyst

Got it. Okay. Thank you.

Our next question comes from the line of David Barden from Bank of America. Your line is open. Please go ahead.

David Barden -- Bank of America -- Analyst

Hey, guys. Thanks so much. Just follow-up a couple of things. So, I guess, first, Jeff, I think last quarter when we were talking about the services business, you said you didn't see any reason for there to be a material change. 2Q, 1Q, obviously there was a change. You kind of listed off a number of things that were contributing factors, but was it really like how quickly the C-Band deployment came out of the gates or was it really how quickly maybe T-Mobile came out of the gates or was it just -- everything just turned out to be better than expected?

Jeffrey A. Stoops -- Director, President and Chief Executive Officer

Really more of the latter. I mean, C-Band came out quicker. DISH came out quicker. T-Mobile continues to be extremely strong.

David Barden -- Bank of America -- Analyst

And just with respect to the DISH deployment, maybe you can comment on this, maybe you can't. But is it -- they've obviously publicly announced what their plan is to build up the Vegas market. Is this kind of bump that you saw specifically related to that or is there something grander that's going on that maybe we haven't heard about yet?

Jeffrey A. Stoops -- Director, President and Chief Executive Officer

Our work's pretty well spread out, David. I'm not sure exactly how they geographically defined those comments you made, but we -- we're seeing a fair spread to the geography.

David Barden -- Bank of America -- Analyst

Okay. Interesting. So just a couple of housekeeping ones. The Tanzania contract, is that all denominated in shillings?

Brendan T. Cavanagh -- Executive Vice President and Chief Financial Officer

The purchase price? Are you asking about the purchase price or the lease back?

David Barden -- Bank of America -- Analyst

The leasing -- the leasing contract.

Brendan T. Cavanagh -- Executive Vice President and Chief Financial Officer

It's roughly -- well, this includes the other third-party. So, I don't know the exact breakdown but the total leasing revenue that's contracted is about 67% in US dollars when you exclude the pass-through stuff.

David Barden -- Bank of America -- Analyst

Got it. Okay.

Brendan T. Cavanagh -- Executive Vice President and Chief Financial Officer

Most of the space it's rented in US dollars. The energy pass-through is all shillings.

David Barden -- Bank of America -- Analyst

Got it. Got it. Okay. And then, my last one if I could, sorry, the roughly $100 million, $95 million that's not Tanzania that you got invested. Where did you guys put that money this quarter?

Brendan T. Cavanagh -- Executive Vice President and Chief Financial Officer

I'm sorry. The what?

David Barden -- Bank of America -- Analyst

Sorry. The $95 million to $100 million that you guys -- that's not part of the Tanzania deal that got spent this quarter. Where did that go?

Brendan T. Cavanagh -- Executive Vice President and Chief Financial Officer

The $95 million discretionary capex?

David Barden -- Bank of America -- Analyst

Correct.

Brendan T. Cavanagh -- Executive Vice President and Chief Financial Officer

Yeah. It went into various acquisitions, also some new builds. We mentioned we built about 100 sites during the quarter, so the total capex was up for a number of deals. The deals -- if you're asking where the deals are -- were located it was a mix. There were mostly deals in the US in this quarter.

David Barden -- Bank of America -- Analyst

Okay. Good. All right. Sorry. Thank you, guys.

Brendan T. Cavanagh -- Executive Vice President and Chief Financial Officer

Yeah. Thanks.

Our next question comes from the line of Eric Luebchow from Wells Fargo. Your line is open. Please go ahead.

Eric Luebchow -- Wells Fargo Securities -- Analyst

Great. Thanks for taking the question. I was wondering on AT&T, you didn't mentioned them as one of the customers that had a step change function and activity. Have you seen any change from them since they announced the Warner Media spinoff around C-band urgency? And you mentioned FirstNet as well on your comments. We have presumed that was staring to wind down but maybe you could comment how much longer you expect FirstNet amendment persist?

Jeffrey A. Stoops -- Director, President and Chief Executive Officer

Yeah, AT&T is relatively steady, did not have the same change in velocity that some of the others that we mentioned did. And the first that stuff, I think we are past, well past the halfway point but not close to being finished.

Eric Luebchow -- Wells Fargo Securities -- Analyst

Okay, fair enough. And just wondering too, is there any update or anything to point out on SBA as the data center platform in terms of deal activity and any update on timing when that could potentially become a modestly more material part of the business?

Jeffrey A. Stoops -- Director, President and Chief Executive Officer

Yeah. I believe and I just heard this today internally that we've now gotten our third contract for a true mobile edge computing site. So, that would give us two data centers and three or four mobile edge facilities. So, moving forward, but quite a bit of ways away from reaching that materiality point you referred to.

Eric Luebchow -- Wells Fargo Securities -- Analyst

Okay. Thank you.

Operator

Our next question comes from the line of Colby Synesael from Cowen. Your line is open. Please go ahead.

Colby Synesael -- Cowen -- Analyst

Okay. Thank you. You mentioned the JVs, $125 million. I'm just curious what your ownership stake of that? And why did JV, you obviously can't afford to do that straight up on your own? Is that meant to signal some type of shift in strategy or simply they're the ones that brought the deal to you and therefore were allowed to take a piece of it?

And then, secondly, the new AT&T-DISH partnership, I'm curious if you view that as incrementally negative or positive to your business in, I guess, just the broader tower industry. Thank you.

Jeffrey A. Stoops -- Director, President and Chief Executive Officer

Yeah. The paradigm folks who were responsible for bringing the deal to us, Colby, and had a long relationship with Airtel in Tanzania with their former employer. So that's why we're where we are. I don't think we're disclosing the exact splits other than we are clearly the majority owner in all facets.

In terms of the AT&T-DISH deal, it doesn't really change DISH's requirements with the FCC, which is for their own fixed network. Arguably it could impact their growth beyond that to just roam on AT&T's network, but we'll have to see. I mean, roaming never is the first economic choice. But I mean, it certainly hasn't in any way impacted DISH's case out of the blocks here in 2021.

Colby Synesael -- Cowen -- Analyst

I'll just do a quick follow-up. One of the parts of that agreement is the ability for DISH to effectively give some of its spectrum to AT&T to deploy on its behalf to which then DISH can use. Do you know if that would meet the threshold that the FCC has in terms of their 70% coverage requirement by 2023, i.e., they can effectively just go on AT&T's towers using their spectrum and that would meet the requirement wherever they may choose to do that?

Jeffrey A. Stoops -- Director, President and Chief Executive Officer

I don't know the answer to that.

Colby Synesael -- Cowen -- Analyst

Neither do I, but thank you.

Our next question comes from the line of Matt Niknam from Deutsche Bank. Your line is open. Please go ahead.

Matt Niknam -- Deutsche Bank -- Analyst

Hey, guys. Thanks for taking my question. Just on capital allocation, now that you're back within your target leverage range, I'm wondering how you're thinking about that. How you're sort of prioritizing uses of excess cash post the dividend. And then, specifically, on the M&A front as well, if you can talk about the latest you're seeing both in terms of valuations, the number of opportunities, particularly internationally? Thanks.

Jeffrey A. Stoops -- Director, President and Chief Executive Officer

Well, the number of opportunities internationally is high, prices are high. You need to be very selective. I don't know that we will be able to do a bunch of things like we're doing in Tanzania. I hope we can but I don't -- I don't know that that will be the case.

In terms of capital allocation generally, we continue to believe our shareholders are best suited by a lower dividend, higher dividend growth strategy, gives us the most flexibility, produces very good growth numbers. So, that's what we will continue to pursue there. And given our access to capital and interest rates, we will look to stay fully invested within our target leverage range whether that'd be portfolio growth or stock repurchases.

Matt Niknam -- Deutsche Bank -- Analyst

Got it. Thanks, Jeff.

Operator

Our next question comes from the line of Jeff Kvaal from Wolfe Research. Your line is open. Please go ahead.

Jeff Kvaal -- Wolfe Research -- Analyst

Yes. Thank you for taking the question. I guess, first, would you mind offering us an update on how close you are to bumping up against supply or labor challenges in this market?

Jeffrey A. Stoops -- Director, President and Chief Executive Officer

So far so good. We really haven't seen any issues on the labor side. I mean, the fact that we maintain a sizable in-house crew gives us some flexibility there. And in terms of the equipment side, we've not heard any issues around our customers delivering the equipment to the sites for installation. Now we read about all the same semiconductor issues that you read about. So, I guess that could change but it has not manifested itself so far.

Jeff Kvaal -- Wolfe Research -- Analyst

Okay. And then, secondly, I think Brett asked earlier about the potential for densification on higher frequencies of C-band. What are you hearing from your carrier partners about their propensity to add themselves or do you think that they will figure it out with better antennas, etc, etc?

Jeffrey A. Stoops -- Director, President and Chief Executive Officer

There will be densification. But just like every generational upgrade, you go first to your existing sites because that's the quickest, the best bang for your buck. So this is happening exactly like it always does.

Jeff Kvaal -- Wolfe Research -- Analyst

Okay. Thank you very much.

Operator

Our next question comes from the line of David Guarino from Green Street. Your line is open. Please go ahead.

David Guarino -- Green Street Advisors -- Analyst

Thanks. Can you remind us of the company views on expanding in the new markets and if there's any off limits? And then assuming you are open extend in the new markets. How do you determine whether or not to utilize the JV partner?

Jeffrey A. Stoops -- Director, President and Chief Executive Officer

The last part of your question is based on what Dave would bring to the table and mostly operational in contacts as opposed to capital at least so far. And in terms of -- there is certainly once that are off-limits either by choice or by legal necessity, places like Cuba and China. I mean, we're just not allowed to go there. And then there'd be others where the analysis of the risks outweigh the rewards. In a country where you have very little rule of law and you have the potential for nationalization of assets, those are not going to be markets where we're most excited about.

David Guarino -- Green Street Advisors -- Analyst

That makes sense. And then, how do you handicap the risk in those markets in, I guess, particularly with the Tanzania acquisition, is there a model you guys have internally that you use just with [Speech Overlap]?

Jeffrey A. Stoops -- Director, President and Chief Executive Officer

We look at all kinds of things. And when you get into markets in Africa, most of the work is not around the assets as much as it is around political, regulatory, tax, government. And we spend a lot of time and take in a lot of resources before we make those decisions.

David Guarino -- Green Street Advisors -- Analyst

Okay. That's helpful. And then maybe one last quick one, on the unoccupied towers, the 28,000 as part of the [Indecipherable] transaction, is any activity from those sites showing up in your service revenue yet, or is it still too early for that?

Jeffrey A. Stoops -- Director, President and Chief Executive Officer

Well, it wouldn't show up in our services revenue. The way that that would -- and that would be leasing revenue. And I'm just not -- I know we have some interest. I don't know if it's actually booked to anything or not. Do you know, Brendan?

Brendan T. Cavanagh -- Executive Vice President and Chief Financial Officer

Brendan: I don't believe so, not yet.

David Guarino -- Green Street Advisors -- Analyst

Okay. Thanks. Appreciate it.

And our last question comes from the line of Brandon Nispel from KeyBanc Capital Markets. Your line is open. Please go ahead.

Brandon Nispel -- KeyBanc Capital Markets -- Analyst

Great. Thank you. And thanks for taking the questions. You mentioned backlogs a couple of times, Jeff. Can you quantify the year-over-year change in backlog of signed but not commenced new leases this quarter? And then, just more broadly on build-to-suit, one of your peers has a large-scale build-to-suit program going on. Can you share with us how many towers you plan on building in Tanzania and maybe how you're thinking about build-to-suit more broadly over the next two to three years? Thanks.

Jeffrey A. Stoops -- Director, President and Chief Executive Officer

Brendan, do we have the answer to the first question?

Brendan T. Cavanagh -- Executive Vice President and Chief Financial Officer

Yeah. I don't have the exact number for you, Brandon. It's materially higher, I can say generally, but we can actually look for something to maybe put a percentage increase or something on that for you after the call.

Brandon Nispel -- KeyBanc Capital Markets -- Analyst

Yeah. And in terms of the new builds in Tanzania, we're committed to build hundreds of towers over the next five years. The hope is we increase that. I would point to South Africa, which we -- which is now, I believe, over 1,500 towers, most of which were built. So there's a lot of opportunity there and we will continue to compress it in those areas where we think it's going to provide great returns.

Brendan T. Cavanagh -- Executive Vice President and Chief Financial Officer

And remind us what you are generally looking for in terms of returns from like an NOI yield perspective on build-to-suit sites. Thanks.

Jeffrey A. Stoops -- Director, President and Chief Executive Officer

Well, we're looking for towers that ultimately either with the first, although that's more unlikely, but with the second, get to a 15% cash on investment yield or higher.

Brandon Nispel -- KeyBanc Capital Markets -- Analyst

Great. Thank you.

Jeffrey A. Stoops -- Director, President and Chief Executive Officer

I want to thank everyone for tuning in today and stay tuned. And we look forward to the next time we're together with third quarter results. Thank you.
