Rowan lands $1.5bn in new financing for data center build-out

Rowan Digital Infrastructure has secured more than $1.5 billion in new corporate-level financing capacity, the company announced this week. The figure covers three separate facilities, not one lump sum. Rowan did not disclose pricing, tenor, or covenants for any of them.

The package breaks down as follows:

• A $600 million upsize of Rowan's holding company term loan, led by Aptterra Infrastructure Capital (an infrastructure-focused lender).
• A new $590 million revolving credit facility (a credit line the borrower can draw and repay repeatedly), led by Citibank, N.A.
• A new $355 million letter of credit facility, also led by Citibank, N.A.

Rowan said the facilities serve general pipeline development purposes. That phrase covers a wide range of uses. The company did not specify which projects will draw on which facility, or in what order.

How large is Rowan's total raise?

The company has raised more than $8 billion from more than 40 lenders over the past 18 months. That pace — roughly $5.3 billion per year — places Rowan among the more aggressively financed private data center developers in the United States. It also raises a question the announcement leaves unanswered: how much of that $8 billion is committed versus drawn.

CEO Charley Daitch framed the raise around speed. "Rowan has been built on the thesis that speed to power and deep community engagement will define the next era of digital infrastructure," Daitch said. "With more than 1.2GW already contracted to world-class technology leaders, Rowan maintains an expansive portfolio of strategic locations to continuously scale support for our hyperscale partners."

The 1.2GW contracted figure is the hardest number in the release. Rowan did not name the counterparties. It did not state delivery dates for that capacity either. A gigawatt of contracted power without a schedule is a promise, not a product.

Who is lending?

The revolving credit and letter of credit lender group includes Citibank, N.A., Mizuho Bank, Ltd., MUFG Bank, Ltd., Goldman Sachs Bank USA, Societe Generale, Sumitomo Mitsui Banking Corporation, and Huntington National Bank. Three of those names — SMBC, Mizuho, and MUFG — also helped lead Rowan's $2.9 billion Temple 1 financing earlier this year.

Apterra's co-CEOs, Ralph Cho and Michael Pantelogianis, tied the deal to broader market demand. "Rowan has set a high bar in hyperscale data center development, and we are pleased to build on our relationship through this financing," they said. "Demand for digital infrastructure financing continues to accelerate, and Apterra is well positioned to support leading developers as they scale."

Accelerating demand for financing is not the same as accelerating returns. Lenders have said similar words in prior cycles.

Saad Zaman, managing director at Citibank, N.A., called the facilities "inaugural syndicated corporate credit facilities" — syndicated meaning the risk is spread across multiple banks rather than held by one. "Citi is honored to serve as left lead arranger, bookrunner and administrative agent on Rowan's inaugural syndicated corporate credit facilities, a milestone in the company's evolution that provides scalable relationship capital to support future growth," Zaman said.

What is Rowan, and who owns it?

Quinbrook Infrastructure Partners and Birch Infrastructure founded the company in 2021, under its former name Rowan Green Data. It is developing data centers in Maryland and Oregon, and holds sites in Texas near Temple and San Antonio. Blackstone acquired a significant minority stake earlier this year. The size of that stake was not disclosed, and neither was the valuation.

Legal representation split across four firms. Simpson Thacher & Bartlett LLP advised Rowan on the revolver and letter of credit facility; Dechert LLP represented the lenders. Kirkland & Ellis LLP advised Rowan on the term loan, and Milbank LLP advised the term loan lender group.

The announcement contains no construction milestones, no energization dates, and no disclosed cost of capital. The financing is real. What it buys, and on what timeline, remains Rowan's to demonstrate.
