Management Commentary

First quarter 2026 revenue increased by $173.1 million, or 31%, to $723.2 million, and Gross Profit was $35.8 million compared to $20.3 million in the prior year quarter. Revenue growth was broad-based across all segments, with Canadian Operations leading at 51%, followed by U.S. Gas at 44%, Non-Union Electric at 27%, and Union Electric at 16%. Net loss attributable to common stock in the first quarter was $9.5 million compared to a loss of $17.9 million in the prior year. Adjusted Net Loss for the first quarter was $2.0 million, an improvement of $8.6 million, or 81%, compared to the same quarter last year. Adjusted EBITDA in the first quarter was $32.6 million compared to $24.2 million in the prior year quarter, a 34% year-over-year increase.

Base Revenue, Base Gross Profit, and Base Gross Profit Margin are non-GAAP measures that exclude the impact of storm restoration services, which are highly unpredictable. Base Revenue in the first quarter was $688.7 million versus $531.9 million in the prior year quarter, a 29% increase. Base Revenue growth was primarily driven by increased bid work in the U.S. Gas and Union Electric segments, the inclusion of recently acquired Connect Atlantic Utility Services in the Canadian Operations segment, and increased work hours under MSA in the Non-Union Electric segment. Base Gross Profit was $28.0 million in the first quarter, a 96% increase from $14.3 million reported in the same quarter last year. The improvement in Base Gross Profit was primarily driven by actions taken by the Company to geographically diversify and reduce seasonality in the U.S. Gas segment and increased bid work in the Union Electric segment. Gross Profit Margin was 4.9% in the first quarter, while Base Gross Profit Margin increased to 4.1% in the first quarter from 2.7% in the year prior, driven primarily by strong performance in the U.S. Gas and Union Electric segments.

Centuri's Net Debt to Adjusted EBITDA Ratio was 2.7x as of March 29, 2026, which compares to 3.5x as of March 30, 2025.

Commercial Update

During the first quarter of 2026, Centuri secured approximately $1.3 billion in total bookings, representing a book-to-bill ratio of 1.8x. Bookings for the quarter included more than $250 million of new bid awards, approximately $180 million of new or expanded MSA awards and nearly $900 million of MSA renewals. For 2026, the Company is targeting a book-to-bill ratio of 1.1x to 1.2x.

As of quarter-end, Centuri had a backlog of approximately $6.5 billion, a 10% increase from year-end 2025 and a 44% increase from the first quarter last year. The opportunity pipeline remained $13 billion at quarter end.

Full Year 2026 Financial Guidance

The Company reiterates its full year 2026 guidance.

Base Revenue and Base Gross Profit do not include contributions from storm restoration services, which are unpredictable.

• Base Revenue of $3.15 to $3.45 billion
• Base Gross Profit of $255 to $285 million

Adjusted EBITDA and Adjusted Net Income are non-GAAP measures that include contributions from storm restoration services. Guidance for these measures and Revenue include estimated contributions from storm restoration services based on three-year (2023-2025) averages of $88 million of storm restoration services revenue and $28 million of storm restoration services gross profit.

• Revenue of $3.24 to $3.54 billion
• Adjusted EBITDA of $280 to $310 million
• Adjusted Net Income of $55 to $75 million

Non-GAAP Financial Measures

We prepare and present our financial statements in accordance with GAAP. However, management believes that EBITDA, Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Net Income (Loss), Adjusted Diluted Earnings (Loss) per share ("Adjusted EPS"), Net Debt to Adjusted EBITDA Ratio, Base Revenue, Base Gross Profit, Base Gross Profit Margin, and Free Cash Flow conversion from Adjusted EBITDA, all of which are measures not presented in accordance with GAAP, provide investors with additional useful information in evaluating our performance. We use these non-GAAP measures internally to evaluate performance and to make financial, investment and operational decisions. We believe that presentation of these non-GAAP measures provides investors with greater transparency with respect to our results of operations and that these measures are useful for period-to-period comparisons of results. Management also believes that providing these non-GAAP measures helps investors evaluate the Company's operating performance, profitability and business trends in a way that is consistent with how management evaluates such matters. Because these non-GAAP measures, as defined, exclude some, but not all, items that affect comparable GAAP financial measures, these non-GAAP measures may not be comparable to similarly titled measures of other companies.

EBITDA is defined as earnings before interest, taxes, depreciation and amortization. Adjusted EBITDA is defined as EBITDA adjusted for (i) non-cash stock-based compensation and (ii) separation-related costs. Adjusted EBITDA Margin is defined as the percentage derived from dividing Adjusted EBITDA by revenue. Management believes that EBITDA helps investors gain an understanding of the factors affecting our ongoing cash earnings from which capital investments are made and debt is serviced, and that Adjusted EBITDA provides additional insight by removing certain expenses that are non-recurring and/or non-operational in nature. Management believes that Adjusted EBITDA Margin is useful for the same reason as Adjusted EBITDA, and also provides an additional understanding of how Adjusted EBITDA is impacted by factors other than changes in revenue.

Net Debt to Adjusted EBITDA Ratio is calculated by dividing net debt as of the latest balance sheet date by the trailing twelve months of Adjusted EBITDA. Management believes this ratio helps investors understand our leverage. Net debt is defined as the sum of all bank debt on the balance sheet and finance lease liabilities, net of cash.

Adjusted Net Income (Loss) is defined as net income (loss) adjusted for (i) separation-related costs, (ii) amortization of intangible assets, (iii) non-cash stock-based compensation and (iv) the income tax impact of adjustments that are subject to tax, which is determined using the incremental statutory tax rates of the jurisdictions to which each adjustment relates for the respective periods. Management believes that Adjusted Net Income (Loss) helps investors understand the profitability of our business when excluding certain expenses that are non-recurring and/or non-operational in nature. Adjusted EPS is defined as Adjusted Net Income (Loss) divided by weighted average diluted shares outstanding.

Base Revenue is defined as total revenue, net adjusted to exclude revenue attributable to storm restoration services. Base Gross Profit is defined as gross profit adjusted to exclude gross profit attributable to storm restoration services. Base Gross Profit Margin is calculated by dividing Base Gross Profit by Base Revenue. Revenue derived from storm restoration services varies from period to period due to the unpredictable nature of weather-related events, and when this type of work is performed, it typically generates a higher profit margin than base infrastructure services projects due to higher contractual hourly rates given the nature of services provided and improved operating efficiencies related to equipment utilization and absorption of fixed costs. While storm restoration services remain a key capability of the Company, Management believes these non-GAAP measures are more suitable disclosures for evaluating fundamental business performance and for comparison purposes.

Free Cash Flow is defined as cash flow from operations less net capital expenditures. Net capital expenditures is defined as capital expenditures, net of proceeds from sale of property and equipment. Free Cash Flow conversion is defined as Free Cash Flow divided by Adjusted EBITDA. Management believes Free Cash Flow conversion from Adjusted EBITDA helps evaluate what proportion of our cash earnings remain available for capital investments and debt service.

Using EBITDA as a performance measure has material limitations as compared to net loss, or other financial measures as defined under GAAP, as it excludes certain recurring items, which may be meaningful to investors. EBITDA excludes interest expense net of interest income; however, as we have borrowed money to finance transactions and operations, or invested available cash to generate interest income, interest expense and interest income are elements of our cost structure and can affect our ability to generate revenue and returns for our stockholders. Further, EBITDA excludes depreciation and amortization; however, as we use capital and intangible assets to generate revenue, depreciation and amortization are necessary elements of our costs and ability to generate revenue. Finally, EBITDA excludes income taxes; however, as we are organized as a corporation, the payment of taxes is a necessary element of our operations. As a result of these exclusions from EBITDA, any measure that excludes interest expense net of interest income, depreciation and amortization and income taxes has material limitations as compared to net loss. When using EBITDA as a performance measure, management compensates for these limitations by comparing EBITDA to net loss in each period, to allow for the comparison of the performance of the underlying core operations with the overall performance of the Company on a full-cost, after-tax basis.

As to certain of the items related to these non-GAAP measures: (i) non-cash stock-based compensation varies from period to period due to changes in the estimated fair value of performance-based awards, forfeitures and amounts granted and (ii) separation-related costs represent expenses incurred post-IPO in connection with the separation and stand up of Centuri as its own public company, including costs incurred in association with Southwest Gas Holdings' sale of its holdings of our common stock, which are not reflective of our ongoing operations and will not recur following the full separation from Southwest Gas Holdings. The most comparable GAAP financial measure and information reconciling the GAAP and non-GAAP financial measures are set forth below. We are unable to provide reconciliations for forward-looking non-GAAP measures without unreasonable efforts due to our inability to project non-recurring expenses and events. Such items could have a substantial impact on GAAP measures of the Company's financial performance.
