ERock Reports Second Quarter 2026 Results

Record Backlog Reaches Approximately $1.7 billion, Up 10x Year-Over-Year

470 MW Anthropic Order Extends Production Commitments Into 2028

HOUSTON - August 11, 2026 - ERock, Inc. (NYSE: EROC) ("ERock" or the "Company"), a leading provider of utility-grade onsite power solutions, today reported financial and operating results for the second quarter ended June 30, 2026, highlighted by record contracted backlog, accelerating demand from AI infrastructure customers, expanded manufacturing capacity and the initiation of full-year 2026 guidance.

Business Highlights

Management Commentary

"The second quarter marked another important milestone for ERock. We secured a 470 MW equipment purchase order from Anthropic, increasing our Contracted Power System Sales Backlog to approximately $1.7 billion and extending our production commitments into 2028. We believe AI infrastructure is fundamentally reshaping power markets, and the need for rapid, utility-grade power continues to accelerate," said John Carrington, Chief Executive Officer of ERock. "To meet that demand, we began assembly operations at our Hyperion manufacturing facility, significantly expanding our production capacity as we execute against record contracted orders. We also commenced construction of the 366 MW El Paso Electric project supporting Meta's data center campus, demonstrating our ability to deliver increasingly large-scale power infrastructure. Our focus remains on safe execution, on-time delivery, disciplined manufacturing expansion and converting our growing backlog into sustained revenue and earnings growth."

Ian Blakely, Chief Financial Officer of ERock, added, "We believe that our second quarter results position us for a meaningful acceleration in the second half of 2026. We expect significantly higher generator deliveries and installations as we execute on multiple large customer projects, which is anticipated to drive substantial growth in revenue and Adjusted EBITDA. Following our IPO, we ended the quarter with $626.6 million of unrestricted cash, no outstanding debt and an undrawn $250 million credit facility. Combined with our expanded manufacturing footprint and record contracted backlog, we believe we are well positioned to execute on the substantial demand we see across AI infrastructure, utilities and other critical power markets."

Outlook

The Company is introducing the following full-year 2026 guidance.

• Revenue: $435 million to $465 million

• Adjusted EBITDA*: $3 million to $9 million

At the midpoint, the revenue outlook represents approximately 2.5x year-over-year growth.

Non-GAAP Financial Measures

Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Gross Profit and Adjusted Gross Margin are financial measures that are not prepared in accordance with GAAP. Each of these non-GAAP financial measures should be read in conjunction with the most directly comparable financial measure calculated and presented in accordance with GAAP.

We believe presenting these non-GAAP financial measures provides useful information because they highlight trends in our underlying operating performance, facilitate consistent comparisons of our core results over time and across peers, and reflect how our management evaluates our business. We also use these non-GAAP financial measures internally for strategic planning, budgeting, forecasting, performance measurement and resource allocation. We believe that providing investors with access to these measures allows for greater transparency and facilitates comparisons to our historical operating results.

These non-GAAP financial measures are not intended to be considered in isolation or as a substitute for the most directly comparable financial measure prepared in accordance with GAAP. In addition, other companies, including companies in our industry, may define these non-GAAP financial measures differently, which may limit their usefulness as comparative measures.

Adjusted EBITDA and Adjusted EBITDA Margin to GAAP Net Loss and Net Loss Margin Reconciliation

Adjusted EBITDA and Adjusted EBITDA Margin are non-GAAP financial measures. Net loss is the GAAP measure most directly comparable to Adjusted EBITDA, and net loss margin is the GAAP measure most directly comparable to Adjusted EBITDA Margin. We define Adjusted EBITDA as net loss before net interest expense; depreciation and amortization expense; income tax expense; stock-based compensation; and other items management deems non-operational or not reflective of ongoing core operations (e.g. changes in fair value of warrant unit liabilities, professional fees associated with debt and equity transactions, legal settlements). We define Adjusted EBITDA Margin as Adjusted EBITDA divided by total revenues.

Adjusted EBITDA and Adjusted EBITDA Margin are utilized by our management and other users of our unaudited condensed consolidated financial statements such as investors, commercial banks, research analysts and others, to assess our operating performance. Management believes these measures are useful because they each allow us to compare our operating performance on a consistent basis across periods. Management also believes Adjusted EBITDA is a useful indicator of our operating performance and Adjusted EBITDA Margin is useful because it provides insight on profitability.

We have not provided a GAAP reconciliation for forward-looking full-year Adjusted EBITDA as a result of the uncertainty regarding, and the potential variability of, reconciling items such as forward-looking stock-based compensation expense and income tax expense. Accordingly, a reconciliation of this non-GAAP guidance metric to its corresponding GAAP equivalent is not available without unreasonable effort. However, it is important to note that material changes to reconciling items could have a significant effect on future GAAP results and, as such, we also believe that any reconciliations provided would imply a degree of precision that could be confusing or misleading to investors.

The tables below present a reconciliation of Adjusted EBITDA and Adjusted EBITDA Margin to net loss and net loss margin:

Adjusted Gross Profit and Adjusted Gross Margin to GAAP Gross Profit and Gross Margin Reconciliation

Adjusted Gross Profit and Adjusted Gross Margin are non-GAAP financial measures. GAAP gross profit is the GAAP measure most directly comparable to Adjusted Gross Profit, and GAAP Gross Margin is the GAAP measure most directly comparable to Adjusted Gross Margin. We define Adjusted Gross Profit as GAAP gross profit, adjusted to exclude reimbursable variable revenues and costs. We define Adjusted Gross Margin as Adjusted Gross Profit divided by total revenues less reimbursable variable revenues. Reimbursable variable revenues and costs represent certain revenues and expenses where we serve as the principal in transactions and control the use and timing of the products and services that are being utilized. These costs represent our primary obligation and are recovered from customers at cost without markup pursuant to the terms of our contracts. While reimbursable variable costs are excluded because they have immaterial net margin impact, they do represent real cash flows and contractual obligations that affect our working capital and liquidity.

We present Adjusted Gross Profit and Adjusted Gross Margin because we believe these measures provide management and investors with a more meaningful view of the underlying economics and profitability of our core operations. Because reimbursable variable revenues and costs are recorded on a gross basis under GAAP and, by design, offset one another with no material contribution to profit, their inclusion in GAAP revenues and cost of revenues can cause reported gross

margin percentages to fluctuate significantly depending on the frequency of underlying activities which can be driven by unpredictable changes in market conditions. By excluding these revenues, Adjusted Gross Margin reflects the margin we earn on the goods and services where we bear economic risk, exercise pricing judgment, and generate value for our customers.

We use Adjusted Gross Profit and Adjusted Gross Margin internally to evaluate segment-level performance, assess pricing and cost trends, and benchmark our profitability against peers whose revenue recognition practices may differ with respect to reimbursable items. We believe this perspective enhances investors’ understanding of the operating leverage and margin trajectory of our business.

Adjusted Gross Profit and Adjusted Gross Margin have limitations as analytical tools. They are not substitutes for GAAP gross profit or GAAP gross margin, and our calculations may not be comparable to similarly titled measures reported by other companies because other entities may not define or calculate these measures in the same manner. In addition, while reimbursable variable costs are excluded because they have immaterial net margin impact, they do represent real cash flows and contractual obligations that affect our working capital and liquidity. Accordingly, these non-GAAP measures should be considered alongside, and not as alternatives to, the GAAP financial measures included in our unaudited condensed consolidated financial statements and consolidated financial statements.
