Transaction Rationale – Digital Realty
Digital Realty is strategically selling a mix of its own legacy assets, as well as sub-scale facilities acquired through its combination with Interxion, which closed in early 2020. This sale of 11 data centers exemplifies Digital Realty’s focus on recycling capital and re-investing the proceeds into more strategic opportunities, such as funding the company’s extensive development pipeline.
Overall, the company telegraphed today’s announcement on its Q4 2020 earnings call. Specifically, Digital Realty’s Chief Financial Officer, Andy Power, noted that this profile of sale would be a 50 bps to 100 bps headwind to the company’s year-over-year Funds From Operations (FFO) growth.
Nevertheless, by Digital Realty executing the sale of 11 data centers to Ascendas Reit, the company is shrewdly positioning itself for sustainable long-term growth. Below we highlight a few points of rationale for Digital Realty.
Recycling Capital
Digital Realty is selling fully-leased, mature data centers where the potential for additional appreciation is limited and is re-investing proceeds into growth developments. Indeed, the company is taking advantage of a meaningful net asset value (NAV) spread between selling data centers at a 6% yield and using those proceeds to develop new facilities at an 8.5% to 12.5% development yield.
Older and Less Differentiated
Digital Realty is ridding itself of a number of older facilities (many are 15 to 20+ years old) and less differentiated (i.e., not connectivity-rich) through the transaction with Ascendas Reit. Indeed, these facilities no longer have modern power supply, back-up power supply, and cooling systems. Therefore, they require a combination of higher maintenance capital expenditures and/or complete refurbishment.
Lease Duration
Digital Realty is enhancing its own lease duration through the transaction with Ascendas Reit, which in turn benefits the company’s credit profile and cost of capital. Specifically, Digital Realty is selling a portfolio which only has a weighted average lease expiry (WALE) of 4.6 years, by rental income. Indeed, this compares to Digital Realty signing new leases during 2020, with a weighted average lease term of 8.5 years. Furthermore, Digital Realty’s top 20 customers by annualized rent, as of Q4 2020, have a weighted average remaining lease term of 6.1 years.
Transaction Rationale – Ascendas Reit
For Ascendas Reit, the transaction with Digital Realty helps to scale the company’s data center portfolio beyond Singapore. Specifically, the portfolio will increase Ascendas Reit’s investment weighting in data centers to 10% (S$1.5bn) of total investment properties of S$15.0bn. Indeed, this 10% figure is up from only 4% or S$0.5bn at year-end 2020. Additionally, Ascendas Reit is taking advantage of what Dgtl Infra previously discussed, being the “Top 5 Data Center Markets in Europe are Booming”, as elaborated on below.
Tier 1 European Data Center Markets
Digital Realty’s portfolio comprises 11 data centers, of which nine (93% of the portfolio by asset value) are located in London, Amsterdam, and Paris, which are Tier 1 data center markets in Europe. Specifically, the cities of Frankfurt, London, Amsterdam, and Paris are commonly referred to as the “FLAP” data center markets.
FLAP Data Center Market Size in Megawatts (MW)

Overall, London, Amsterdam, and Paris rank as the first, third, and fourth largest colocation markets in Europe, respectively. At year-end 2020, these cities had a combined colocation market size of 1,383 megawatts (note this figure excludes Frankfurt).
Strong Take-Up
Take-up of colocation data centers exceeded new supply in 2020 across the FLAP markets. Specifically, this was driven by companies increasing their consumption of cloud services, in turn driving colocation demand from cloud providers. Increasingly, colocation is also satisfying the IT requirements of companies which are growing in scale and complexity.
FLAP Data Center Market Size and Take-Up in Megawatts (MW)

Overall, during 2020, a total of 201 megawatts of take-up occurred in the FLAP markets, which includes Frankfurt (67 megawatts), London (86 megawatts), Amsterdam (32 megawatts), and Paris (17 megawatts).
Power Capacity Growth
New supply in the FLAP markets of 174 megawatts is lower, and thus a favorable comparison to take-up. Specifically, the new supply in 2020 includes Frankfurt (62 megawatts), London (26 megawatts), Amsterdam (57 megawatts), and Paris (29 megawatts).
Vacancy Rates and Absorption
As a result, in 2020, the FLAP markets’ vacancy rate improved to 19%, from 21% in 2019. In 2021, the vacancy rate will fall even further to 17%, driven by a continuation of data center demand.
Market absorption, which represents the number of years it takes for current vacant supply to be fully let, was 2.4 years at year-end 2020. Indeed, this is lower than the 3.0 years of absorption from 2019. Moreover, absorption will decline further to 2.3 years in 2021.
