Analyst · Evercore
Michelle, thank you. Happy Friday morning, everyone, and thank you for participating in our third quarter 2022 earnings call. On today's call with me today are George Johnstone, our Executive Vice President of Operations; our Vice President and Chief Accounting Officer, Dan Palazzo; Tom Wirth, our Executive Vice President and Chief Financial Officer.
Prior to beginning, certain information discussed during our call may constitute forward-looking statements within the meaning of the federal securities law. Although we believe estimates reflected in these statements are based on reasonable assumptions, we cannot give assurance that the anticipated results will be achieved. For further information on factors that could impact our anticipated results, please reference our press release as well as our most recent annual and quarterly reports that we file with the SEC.
So during today's call, Tom and I will review third quarter results, provide an update on our '22 business plan. And after that, Dan, Tom, George and I are available for any additional questions.
Looking back at the quarter, certainly, record inflation, interest rate increases, capital market uncertainty, recessionary fears have significantly changed the operating and financing landscape. The stability of our operating portfolio, evidenced by low forward rollover, protection from operating expense increases on 81% of our leases well position us on the operating margin front, and we will certainly continue to focus on margin improvement as we enter the '23 budget cycle, and we are pleased that our '22 operating and development plans remain on target.
The macro environment, however, certainly impacted our capital program. And while we will continue to select planning and approval efforts, future development starts are on hold unless they are fully pre-leased and until the existing pipeline posts more leasing traction. During the quarter, we also terminated several potential acquisitions and accelerated our refinancing and interest rate management programs that Tom and I will review during the course of our conversation.
From an operating standpoint, we continue to experience higher physical occupancy, now 60% overall with a high of 70% to 75% in the Pennsylvania suburbs. Hybrid attendance, as you might expect, continues in all of our markets, Tuesday through Thursday being the most common in office days. On those high peak days, we're experiencing closer to 70% to 75% attendance from most tenants.
Tenant interest in high-quality work environments remains the order of the day. We see that every day in our tour levels, lease negotiations and deal executions. In fact, 41%, which is up from 32% last quarter, of the new deals in our operating portfolio pipeline are from tenants looking to upgrade from lower quality, less amenitized buildings.
During the third quarter, we executed 513,000 square feet of leases, including 300,000 square feet of new leases. We also posted rental rate mark-to-market of 16.5% on a GAAP basis and 6.9% on a cash basis. Our full year mark-to-market range remains 16% to 18% on a GAAP basis and 8% to 10% on a cash basis.
Absorption for the quarter was 176,000 square feet. Tenant retention was 90%, and we ended the quarter slightly below 91% occupied and 91.8% leased. It's further worth noting that our Philadelphia CBD, University City, the Pennsylvania suburbs and Austin markets, which cover 93% of our portfolio NOI, were a combined 93.8% leased and 93% occupied. Our spec revenue range remains in the $34 million to $36 million range, with $35 million or 100% at the midpoint achieved.
The speculative revenue range represents approximately 1.8 million square feet, of which 1.7 million or 94% is already executed. The portfolio is stable and our forward rollover exposure through 2024 averages 6.5%, which ranks us third out of 17 office REITs. Further, our annual rollover exposure through 2026 is 7.3%, also ranking us third out of 17 REITs, and we continue efforts to reach out into the maturity curve on a daily basis.
We did post FFO of $0.36 per share, which was 2% -- above $0.02 above consensus estimates. We beat those estimates, primarily due to the combination of improved operating results, lower interest costs and a higher-than-anticipated gain on the 3151 Market Street formation. So while exceeding consensus estimates for the quarter, we're keeping our FFO range unchanged at $1.36 to $1.40 per share, primarily due to the unstable interest rate environment and the impact of any potential sales.
Based on 2022 leasing activity and higher EBITDA, our third quarter net debt-to-EBITDA decreased to 7.2x on a combined basis. And based on our development activity, we are projecting to be at the upper end of our current range of 6.6 to 6.9 at the end of the year. Our core EBITDA metric of a range of 6 to 6.3 focuses on our operating portfolio by eliminating joint venture and active development and redevelopment projects. We continue to believe this is a more accurate measure of how we manage our core portfolio, and those metrics are noted on Page 31 of our sup.
In looking at leasing activity, [indiscernible] remained encouraging during the third quarter. Our total leasing pipeline is 4.8 million square feet, broken down between 1.5 million square feet on the operating portfolio and 3.3 million on the development project. The 1.5 million square foot existing portfolio pipeline is up 430,000 square feet from last quarter, with approximately 208,000 square feet in advanced stages of lease negotiations.
Also, as I mentioned, 41% of that new deal pipeline are prospects looking to move up the quality curve. The 3.3 million square foot leasing pipeline on our development projects increased over 300,000 square feet during the quarter. Deal conversion rate in the second quarter was 40%, up from 38% last quarter and in line with prepandemic levels from the fourth quarter of 2019.
Another good sign is tenants continue to accelerate their decision time line. This past quarter, the median deal cycle time improved by an additional 4 days and is now equal to pre-pandemic levels. In looking at liquidity and dividends, we currently have $350 million availability under our $600 million line of credit. With our targeted development spend and absent any other financing sources, we anticipate having over $300 million of that line available at the end of 2022.
Our $0.76 per share dividend is well covered with a 53% payout ratio. We know there is a focus on near-term maturities, so Tom and I will address them during our comments. We have a $350 million bond maturity in February of '23. We are confident we could refinance these bonds in the investment-grade market and continue to explore shorter dated maturity bond options in that investment-grade market.
We are also, however, actively pursuing several other more flexible financing options, including secured and unsecured property and portfolio financings through the bank and other traditional institutional financing sources. This $350 million bond in February is our only wholly-owned balance sheet maturity until our next bond matures in October of 2024.
We do have 2 joint ventures with nonrecourse loans maturing in 2023. We are already underway with extension discussions and exploring other financing sources for those loans as well. The first is a $208 million loan in our Commerce Square joint venture. This is a very low levered financing with over an 11% debt yield on income in place. We're already in discussions with the existing lender for an extension as well as exploring other financing sources.
The second maturity in the joint venture framework is in August of '23 and refinancing and discussion efforts are underway there as well. From a capital allocation standpoint, we continue to assess forward capital spend. In addition, we are marketing an additional $200 million of properties for sale as part of our ongoing price discovery process.
In looking at our development opportunity set, as I mentioned earlier, other than fully leased build-to-suit opportunities, all future development starts are on hold, pending more leasing on the existing pipeline and certainly more clarity on the cost of debt capital and cap rates. We also terminated 2 potential acquisitions that we had underway since the quarter end.
When you look at our development pipeline, our remaining total Brandywine net funding obligation on all of our wholly-owned and joint venture development projects is $115 million, which includes $11 million remaining to fund on our 3151 Market project and $17 million for remaining tenant improvement spend on our now 96% leased 405 Colorado.
As you'll note on that page in the sup, our equity requirements on Schuylkill Yards West and Uptown ATX Block A are fully funded. We also announced as part of our press release, the commencement of our 155 King of Prussia Road project. This 145,000 square foot project is 100% leased to Arkema and will serve as their North American headquarters. We anticipate the project stabilizing in the fourth quarter of '24. We are already proceeding on a 60% loan-to-cost construction loan to help finance this project. And based on that, as of quarter end, we only have $18 million left to fund on this project, which again is included in the above $115 million total forward spend obligation.
Our 250 King of Prussia Road project in Radnor is now over 53% leased, having signed 28,000 square feet of leases this quarter. The current pipeline totals 254,000 square feet. And again, our remaining $20 million spend on this project is included in the $115 million forward spend noted on that schedule.
In looking at University City, our B.Labs project is doing extremely well and is leased to 15 different companies. A number of these companies are already expressing needs for additional space. So building on this success, we do plan to convert another floor totaling approximately 27,000 square feet to meet existing incubator demand. And in addition, as noted on previous calls, feasibility studies remain underway to add another 78,000 square feet of life science capable space through Floor 9 including space being vacated by an existing tenants.
On looking at Schuylkill Yards, our 3025 JFK project, which is a life science residential tower remains on time and on budget for Q3 '23 delivery. We currently have an active pipeline, totaling just shy of 400,000 square feet, which is up 73,000 square feet from last quarter. The pipeline is expected to continue as construction progresses. In fact, now with the superstructure nearing completion, we have done over 100 hard hat tours for prospects and their representatives. As I noted earlier, our $56.8 million equity commitment is fully funded, our partners' equity investment is also fully funded, and the first funding of our construction loan has commenced.
As you know from our supplemental package, in Schuylkill Yards, we can do about -- develop another 3 million square feet of additional life science space. And as another step in the execution of that plan, our 3151 Market project, which is a 441,000 square foot dedicated life science building is on schedule and on budget. That project will be completed in the second quarter of '24. On that project, we have a leasing pipeline of about 400,000 square feet, and we plan on obtaining a construction loan in the 50% loan-to-cost range early in '23 as funding of that construction loan is not required until the third quarter of next year.
Construction is also on time and on budget at Block A, at our Uptown ATX development. In addition, as noted in our announcement, during the quarter, we did close on our construction loans totaling $207 million. On the office component, which is 348,000 square feet, our leasing pipeline is 1.5 million square feet.
When we take a look at our development pipeline, the key phrase is with that forward pipeline is timing flexibility as evidenced by low land basis per FAR and product diversity. Of the 14.2 million square feet we can build, we can do about 3 million to 4 million square feet of total life science space and over 4,000 multifamily units. And our overlay approvals, particularly at Schuylkill Yards and Uptown ATX give us a degree of flexibility to further adjust that mix to meet market demand. As evidence of the low land basis per FAR, you will note in our statements that we did record an $8.7 million land gain on the land contribution to our joint venture.
And looking at other capital components, while our '22 business plan did not and does not specify a dollar volume of property dispositions, we have been active on this front as well. As I mentioned, we have over $200 million of assets in the market for price discovery. We do anticipate continuing to sell select noncore land parcels during '23 as we did in '22. We do have approximately $110 million of assets under firm agreements of sale that we do expect to close prior to year-end.
We also further expect that sales of select properties out of our existing joint ventures will occur over the next 4 quarters. And dollars generated from these activities will certainly be used to reduce leverage, fund our development pipeline and look for higher-yielding growth opportunities.
Tom will now provide an overview of our financial results.
