Marathon Digital's 2025 Q4 Starwood JV: NOI and Lease Rate Insights

Financial Analysis: Expected NOI Yield and Target Lease Rates per MW for Starwood JV Projects under Typical Hyperscaler Leases

Based on Marathon Digital Holdings, Inc.’s (MARA) 2025 Q4 earnings call and related disclosures, the following points summarize the available information and provide an analytical view on expected Net Operating Income (NOI) yield and lease economics per megawatt (MW) for the Starwood JV projects targeting hyperscaler tenants:

---

1. NOI Yield Expectation

• MARA expects the Starwood joint venture (JV) to generate meaningful net operating income (NOI) and free cash flow over time, which will reduce earnings volatility compared to pure Bitcoin mining operations. This reflects a strategic shift from purely volatile crypto operations toward infrastructure-like contracted cash flows ¹².

• The JV infrastructure is conceived to deliver more than 1 GW of near-term IT capacity, with a pathway to exceed 2.5 GW over time, emphasizing scale and institutional-grade development ³⁴.

• While exact NOI yield targets or percentages per MW are not disclosed explicitly in the filings, MARA’s CFO highlights that the partnership will materially improve MARA’s long-term NOI profile and cash flow visibility, implying stable, contractually-backed returns rather than spot-market exposure ¹².

• The JV’s “institutional-grade” tenants (hyperscale cloud, AI, HPC customers) demand lower risk profiles, which typically translates into lease contracts with long-term, predictable, and possibly escalated lease payments that mimic infrastructure returns more than commodity leases ³².

• Management prefers projects sized in hundreds of megawatts with large hyperscale tenants, not small 40-50 MW builds, implying economies of scale and higher NOI potential per project ⁵⁶.

• Flexibility to retain up to 50% ownership in JV projects allows Marathon to capture part of operating cash flow as NOI aligned with their equity stake. However, the lease economics vary by tenant and project details, which are still under negotiation ⁵⁷.

2. Lease Rate Components and Target Metrics per MW

• Although specific lease rates per MW are not disclosed, several qualitative factors guide the economics:

  • Powered Sites & Infrastructure: MARA’s existing energized sites provide a highly valuable platform for hyperscalers since power is already on and readily available, which decreases capital intensity and speeds up deployment ⁸⁶⁹.

  • Below-market Power Cost Advantage: MARA operates with energy costs as low as $0.04 per kWh in owned sites, which is a key factor to offer competitive lease rates while retaining strong NOI margins ¹⁰.

  • Load Balancing Flexibility: MARA’s ability to toggle between Bitcoin mining load and HPC/AI tenant compute load enables optimization of power usage and revenue — mining load fills unused capacity at preferential prices and smoothes utilization, enhancing site-level cash flow ¹¹⁷.

• Lease contracts with hyperscalers generally include:

  • Long-term, fixed or inflation-escalated payments per MW of IT load.
  • Tenant design and build-to-suit adjustments funded by the JV.
  • Power infrastructure costs embedded or charged as separate pass-throughs or included in a blended lease rate.

• Starwood’s decades of experience in data center real estate and its relationships with 3 of 4 Tier 1 hyperscalers reduce execution risk and support market-competitive lease structures that offer strong returns to joint venture partners ³⁹¹².

3. Market Comparables and Context

• Industry data center lease rates to hyperscalers typically range from $150k to $300k per MW annually (not from filing but general market knowledge). Given MARA’s power cost advantage and ability to operate at scale, their NOI yield per MW could be expected to be at the higher end of the market range or better.

• The partnership with Starwood aims to attract high-credit tenants who sign long-term leases (9-12 months or shorter closing timeline due to Starwood’s relationships) with strong balance sheets, supporting stable NOI with limited volatility ⁵⁹.

• MARA’s ability to also monetize Bitcoin mining in off-periods offers an incremental revenue layer that enhances overall site economics beyond the fixed lease rate to hyperscalers ¹¹.

4. Summary of Key Points

Conclusion

Marathon’s Starwood JV projects targeting hyperscale cloud and AI tenants are positioned to generate stable, meaningful net operating income through long-term leases backed by investment-grade hyperscalers. Though specific NOI yields and per MW lease rates are not publicly detailed, management emphasizes:

• Leveraging existing powered sites and below-market power costs to improve NOI margins,
• Retaining economically substantial ownership stakes, and
• Achieving rapid, credit-backed lease execution through Starwood’s industry relationships.

This JV effectively transitions MARA’s asset base from volatile Bitcoin mining cash flows toward more resilient, infrastructure-like NOI streams with a potential NOI yield reflective of competitive hyperscale data center leases typically commanding several hundred thousand dollars per MW per year in lease payments.

If/when MARA discloses specific lease rates or NOI percentages, more precise quantification will be available. For now, investors should interpret the Starwood JV as a strategic move to accelerate and stabilize cash flow generation through large-scale, long-term hyperscaler leases anchored by MARA’s low-cost, power-advantaged infrastructure.
