Ares secondaries funds lift Sabey data center commitment past $500 million

Ares Management's secondaries funds have expanded their investment in Sabey Data Center Properties, taking the firm's cumulative commitment to the operating data center platform above $500 million. Sabey Corporation and National Real Estate Advisors announced the follow-on this week, three months after Ares's original minority equity investment in SDCP was disclosed in July 2026, and gave no size or terms for the incremental commitment. The more-than-$500 million figure is therefore the total position, not the new money; the vehicle behind the second check is the part that needs explaining.

Behind that position sits 275MW and roughly four million square feet of capacity across the United States, with an expansion pipeline Sabey expects to reach approximately 737MW by 2033. Its sites in operation or development run from Quincy, Seattle and East Wenatchee in Washington, through Umatilla, Oregon and Indianapolis, to Austin, New York City and Ashburn, Virginia — the market where the state has cut aid eligibility at 25 megawatts and moved to bar nondisclosure agreements around new projects, changes this publication has argued will reprice the pipeline rather than stop it.

The vehicle is where the capital question sits. Secondaries funds are built to buy interests from existing holders, exchanging liquidity for a discount to net asset value, which makes them an unusual source of follow-on equity for a company the manager already holds. All the announcement says is that Ares Secondaries funds expanded their investment in SDCP, which leaves open whether the new commitment sits inside the same vehicles, alongside them, or through an affiliated structure. Nothing in the coverage suggests the arrangement is out of character for Ares's real estate secondaries platform, and the fund family may simply be the named buyer while the economics run elsewhere. Either way, the desk that normally supplies exits is the one writing the follow-on.

The partner commentary leaves no doubt about the thesis. Kevin Verdi, executive vice president and chief investment officer at National Real Estate Advisors, called the follow-on a reflection of "continued conviction in SDCP's long-term value proposition and growth trajectory," tying the platform's growth to "the digital infrastructure needed to support the next generation of cloud and AI demand." Tim Mirick, president of Sabey Data Center Properties, said the additional commitment "reflects confidence in the strength of our platform and our ability to develop and operate the mission-critical infrastructure our customers rely on," while Jamie Sunday, co-head of real estate secondaries at Ares, cited "significant runway for growth" and the relationship with the Sabey and National teams.

Ares was founded in 1997 and manages $671 billion, owns Ada Infrastructure outright, and has previously provided funding to Vantage and EdgeConneX. The Ada buildout is its own study in the distance between an announced target and a funded pipeline — a 900MW Japan ambition whose named projects cover roughly two-thirds of it, as this publication reported in September. Sabey's 275MW is the other kind of asset entirely: in service, and now carrying a second check from the same investor.

This is the same hierarchy this publication has described across digital infrastructure: the stack prices the anchor tenant and the operating asset rather than the shell, and tenantless development now sits a step below. A total commitment above $500 million for a minority position in an operating platform is a mark at the top of that hierarchy, and the second time Ares has paid at that level. Minority equity also carries the least control over when the next tranche of capacity gets built and the longest road to a realization, a duration profile a secondaries fund can hold more easily than a development vehicle.

What the next check buys is less clear. A pipeline targeting roughly 737MW by 2033 is a multi-stage program, and whether Ares Secondaries is the vehicle that funds it, or one of several, will surface in future disclosures. For now the disclosed facts stay narrow: a second commitment, a total above $500 million, 275MW already in service, and a growth target that runs to 2033. Whether that target is met turns on permitting calendars more than checkbooks — the argument this publication has been making in Virginia and elsewhere — and on whether Ares keeps adding at this price.
