Management Commentary

“We executed well in the third quarter, with record production and deliveries that drove record quarterly revenue and profitability,” said John Carrington, Chief Executive Officer of ERock. “We began construction at the El Paso Electric facility for Meta, and that project remains on track for completion in mid-2027. We are expanding our manufacturing capacity by 900 MW per year with a new facility in Houston (Atlas). When complete, our total capacity is expected to reach 2.1 GW per year to serve the strong demand for our product. Since the end of the quarter, we added new bookings of more than $300 million, setting a new backlog record and providing revenue and margin visibility into 2028. Our differentiated product and service offerings continue to resonate with customers, and we remain focused on disciplined expansion to meet their needs.”

Ian Blakely, Chief Financial Officer of ERock, added, “The third quarter marked an inflection point with revenue growing nearly 4x quarter-over-quarter, driving our first profitable quarter as a public company. We reported $8.9 million of net income and $12.6 million of Adjusted EBITDA. This reflected an improvement of $76.6 million of net income and $26.6 million of Adjusted EBITDA, demonstrating the operating leverage embedded in our business. We expect continued revenue and profitability growth in the fourth quarter and are reaffirming our 2026 guidance. Our robust balance sheet and strong liquidity, coupled with our backlog and unique products and services, give us confidence to expand our manufacturing capacity to meet strong customer demand.”

Outlook

The Company is reaffirming its 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 Income (Loss) and Net Income (Loss) Margin Reconciliation

Adjusted EBITDA and Adjusted EBITDA Margin are non-GAAP financial measures. Net income (loss) is the GAAP measure most directly comparable to Adjusted EBITDA, and net income (loss) margin is the GAAP measure most directly comparable to Adjusted EBITDA Margin. We define Adjusted EBITDA as net income (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 net income (loss) 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 income (loss) and net income (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.
