Revenue Momentum Accelerates on ALM and Data Centers
Revenue growth accelerated to 18.5% year-over-year in 2026Q2, reaching $2.0B, driven by ALM acquisitions and data center expansion, as reported in the latest quarterly filing.
The 18.5% revenue growth in 2026Q2 marks the strongest quarter in the series, up from 11.6% in 2025Q2. This acceleration appears to be fueled by the aggressive expansion into Asset Lifecycle Management (ALM) and data center capacity, which are higher-growth but more cyclical segments. While the legacy records management business likely provides a stable base, the incremental growth is increasingly dependent on these capital-intensive ventures, which may introduce volatility.
NOI Margin Drifts Lower Amid Mix Shift
NOI margin declined from 55.9% in 2025Q2 to 52.8% in 2026Q2, reflecting a revenue mix shift toward lower-margin ALM and data center operations, according to the income statement data.
The 310 basis point year-over-year decline in NOI margin suggests that the growth segments carry structurally lower property-level profitability compared to traditional storage. This is consistent with the higher utility and labor costs associated with data centers and ALM services. Investors should monitor whether this margin compression stabilizes as these segments mature, or if it signals a permanent shift in the earnings quality.
FFO Per Share Volatile, AFFO Deeply Negative
FFO per share swung from $0.73 in 2025Q2 to $1.28 in 2026Q2, but AFFO remained negative at -$202.2M, indicating significant non-cash or growth-related deductions, as per the latest financials.
The 77.7% year-over-year FFO growth in 2026Q2 is impressive, but the persistent negative AFFO across all quarters raises concerns about the sustainability of the dividend. The gap between FFO and AFFO likely reflects heavy capital expenditures for data center build-outs and racking systems, which may be classified as growth rather than maintenance. If these investments do not generate sufficient returns, the dividend coverage could remain under pressure.
Depreciation Distorts GAAP Earnings
GAAP net income margin was only 5.1% in 2026Q2 despite strong FFO, highlighting the significant depreciation charges on real estate and equipment, as disclosed in the income statement.
The wide gap between net income and FFO underscores the heavy depreciation burden, particularly from data center equipment with shorter useful lives. This distortion makes FFO a more reliable indicator of cash-generative potential, but investors should also consider that some of this depreciation may represent real economic costs as technology becomes obsolete. The negative AFFO suggests that maintenance capex is substantial, warranting scrutiny of the classification of growth versus maintenance spending.
Organic Growth Masked by Acquisition Spree
Same-store metrics are not disclosed, but the 18.5% revenue growth in 2026Q2 likely overstates organic momentum given the aggressive ALM acquisitions, based on the reported figures.
Without same-store disclosure, it is difficult to isolate organic performance from acquisition-driven growth. The rapid expansion into ALM suggests that a significant portion of revenue growth is inorganic. Investors should demand more transparency on same-store NOI trends to assess the underlying health of the legacy storage business and the integration success of acquired assets.
Earnings Quality Questioned by Negative AFFO
Despite record revenue, AFFO has been negative for ten consecutive quarters, raising doubts about the true cash earnings power and dividend sustainability, as per the financial statements.
The persistent negative AFFO is a red flag that the company may be overstating its distributable cash flow by capitalizing costs that are effectively maintenance in nature. If the heavy capital expenditures are not generating adequate returns, the dividend could be at risk. Furthermore, the reliance on debt to fund growth, as evidenced by the strained balance sheet, amplifies the risk if interest rates remain elevated. Investors should closely monitor the trajectory of AFFO and the composition of capex.
