"I am delighted to report that our transformative combination with Argos USA is off to a strong start as we effectively, swiftly, and safely move to integrate our two businesses," remarked Anne Noonan, Summit Materials President and CEO. "This progress, together with a better than anticipated first quarter, improved synergy visibility, and a positive outlook allows us to increase the lower end of our full year 2024 guidance range. Today's updated outlook reflects our view that pricing momentum is healthy and persistent across our businesses, cost headwinds are decelerating, and demand conditions, in general, are accommodating of material margin expansion in 2024. We expect this, combined with meaningful synergies, self-help operational improvements, and a more profitable portfolio will catalyze superior value creation for Summit shareholders. Moreover, with our leverage well below target we have a balance sheet that complements a promising pipeline of accretive, aggregates-oriented acquisition targets and the organization is well positioned to continue its financial and strategic progress in the year ahead."

2024 Guidance

For the full year 2024, Summit is currently projecting Adjusted EBITDA of approximately $970 million to $1,010 million and capital expenditures of approximately $430 million to $470 million.

Adjusted EBITDA is a non-GAAP measure. Refer to the "Non-GAAP Financial Measures" section for more information. Because GAAP financial measures on a forward-looking basis are not accessible, and reconciling information is not available without unreasonable effort, we have not provided reconciliations for forward-looking non-GAAP measures. For the same reasons, we are unable to address the probable significance of the unavailable information, which could be material to future results.

First Quarter 2024 | Total Company Results

Net revenue increased $366.0 million, or 89.9% in the first quarter to $773.2 million, including the partial quarter impact of the Argos USA assets. In the quarter, $378.5 million of revenue was recognized from recent acquisitions which more than offset a decrease of $21.7 million in net revenue related to divestitures. Organic prices increased across all lines of business.

Operating loss increased in the first quarter to $44.9 million, driven exclusively by $61.3 million of transaction and integration costs related to the Argos USA transaction. Summit's operating margin percentage for the three months ended March 30, 2024, decreased to (5.8)% from (3.8)%, from the comparable period a year ago primarily reflecting the aforementioned transaction and integration costs related to the Argos USA transaction.

Net loss attributable to Summit Inc. increased to $66.9 million, or $(0.40) per basic share, compared to $30.8 million, or $(0.26) per basic share in the comparable prior year period. Summit reported adjusted diluted net loss of $19.9 million, or $(0.12) per adjusted diluted share, compared to an adjusted diluted net loss of $30.7 million, or $(0.26) per adjusted diluted share, in the prior year period.

Adjusted EBITDA increased $80.0 million, or 194.2%, to $121.2 million reflecting the integration of and strong contribution from the new Argos USA cement assets as well as strong organic pricing growth across all lines of business.

Aggregates adjusted cash gross profit margin was 40.5% in the first quarter as compared to 35.0% in the prior year period. Aggregates sales volume decreased 7.3% in the first quarter. Organic aggregates sales volumes decreased 8.3% reflecting poor weather conditions in many markets and restrained residential activity. Average selling prices for aggregates increased 10.8%, reflecting both carry-over pricing from 2023 as well as price increases implemented across markets to start the year. Pricing growth was strongest in the East Segment, but both the West and East Segments recognized double-digit price increase over the prior year period.

Cement Business: Cement Segment net revenues increased to $231.8 million in the first quarter. Cement Segment adjusted cash gross profit margin increased to 30.6% in the first quarter, compared to 9.6% in the prior year period, driven by pricing gains, operational efficiencies, and favorable year-on-year kiln fuel costs. Sales volume of cement increased 416.0% on a nominal basis and decreased 2.7% organically on unfavorable weather conditions. Organic average selling prices increased 5.6% in the first quarter due pricing actions implemented in 2023 and price increases that went into effect at the beginning of 2024.

Products Business: Products net revenues were $359.1 million in the first quarter, up 100.0% versus the prior year period. Products adjusted cash gross profit margin decreased to 12.3% in the first quarter. Organic average sales price for ready-mix concrete increased 8.3%, driven by pricing growth across all markets, including our key markets of Houston and Salt Lake City. Organic sales volumes of ready-mix concrete decreased 15.1% due to reduced residential activity. Organic average selling prices for asphalt increased 5.8%, due to pricing gains both the West and East Segment. Organic asphalt sales volume increased 9.4%, fueled by public infrastructure growth.

First Quarter 2024 | Results By Reporting Segment

West Segment: The West Segment operating income increased $6.9 million to $12.6 million and Adjusted EBITDA of $43.4 million in the first quarter increased 32.8% versus the prior year period reflecting sustained pricing momentum, more favorable weather conditions in certain markets relative to the prior year period, and the contribution from Argos USA ready-mix concrete plants in the Houston market. Aggregates revenue increased 1.9%, including 10.0% pricing growth led by Houston and British Columbia performance while volume declined 7.4% due, in part, to unfavorable weather conditions in South Texas. Ready-mix concrete revenue increased 29.5% on 6.4% pricing growth and 21.9% volume growth. Organic ready-mix pricing increased 8.5% and because of subdued private construction activity, organic ready-mix volumes decreased 16.8% in the period. Asphalt revenue increased 16.6% due to volumes growth of 10.1%, including organic growth of 9.4%. Asphalt pricing increased 5.6% with strong gains in North Texas.

Non-GAAP Financial Measures

The Securities and Exchange Commission ("SEC") regulates the use of "non-GAAP financial measures," such as Adjusted Net Income (Loss), Adjusted Diluted Net Loss, Adjusted Diluted EPS, Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Cash Gross Profit, Adjusted Cash Gross Profit Margin, and Free Cash Flow which are derived on the basis of methodologies other than in accordance with U.S. generally accepted accounting principles ("U.S. GAAP"). We have provided these measures because, among other things, we believe that they provide investors with additional information to measure our performance, evaluate our ability to service our debt and evaluate certain flexibility under our restrictive covenants. Our Adjusted Net Income (Loss), Adjusted Diluted Net Loss, Adjusted Diluted EPS, Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Cash Gross Profit, Adjusted Cash Gross Profit Margin, and Free Cash Flow may vary from the use of such terms by others and should not be considered as alternatives to or more important than net income (loss), operating income (loss), revenue or any other performance measures derived in accordance with U.S. GAAP as measures of operating performance or to cash flows as measures of liquidity.

Adjusted EBITDA, Adjusted EBITDA Margin, and other non-GAAP measures have important limitations as analytical tools, and you should not consider them in isolation or as substitutes for analysis of our results as reported under U.S. GAAP. Some of the limitations of Adjusted EBITDA, Adjusted EBITDA Margin and other non-GAAP measures are that these measures do not reflect: (i) our cash expenditures or future requirements for capital expenditures or contractual commitments; (ii) changes in, or cash requirements for, our working capital needs; (iii) interest expense or cash requirements necessary to service interest and principal payments on our debt; and (iv) income tax payments we are required to make. Because of these limitations, we rely primarily on our U.S. GAAP results and use Adjusted EBITDA, Adjusted EBITDA Margin and other non-GAAP measures on a supplemental basis.

Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Cash Gross Profit, Adjusted Cash Gross Profit Margin, Adjusted Net Income (Loss), Adjusted Diluted Net Loss, Adjusted Diluted EPS, and Free Cash Flow reflect additional ways of viewing aspects of our business that, when viewed with our GAAP results and the accompanying reconciliations to U.S. GAAP financial measures included in the tables attached to this press release, may provide a more complete understanding of factors and trends affecting our business. We strongly encourage investors to review our consolidated financial statements in their entirety and not rely on any single financial measure. Reconciliations of the non-GAAP measures used in this press release are included in the attached tables.
