Raises 2023 Adjusted EBITDA Guidance

DENVER, May 3, 2023 /PRNewswire/ -- Summit Materials, Inc. (NYSE:SUM) ("Summit," "Summit Materials," "Summit Inc." or the "Company"), a leading vertically integrated construction materials company, today announced results for the first quarter ended April 1, 2023. All comparisons are versus the quarter-ended April 2, 2022 unless noted otherwise.

"It's clear by our record first quarter results that we have a solid head start as we enter the prime construction season," commented Anne Noonan, Summit Materials President and CEO. "As expected and due to January pricing actions, we witnessed significant pricing momentum across each of our lines of business and in all of our markets. Those pricing gains, coupled with demand resiliency and solid operational execution, fueled our second consecutive quarter of year over year margin growth. This early performance, together with stronger pricing and improved demand expectations gives us the confidence to raise our full year Adjusted EBITDA outlook. And while second half visibility is challenging, particularly when it comes to residential demand, supply chain constraints, and uncertain cost trends, we feel we have enough within our control to deliver on these upgraded financial commitments for 2023."

Scott Anderson, Executive Vice President and CFO of Summit Materials added, "On top of our first quarter financial progress, we continue to press forward on our strategic goals. Our commercial and operational excellence initiatives are well underway and expected to produce margin-enhancing results this year. Consistent with our Elevate Summit plan, we are pursuing a capital allocation strategy that prioritizes growth. Organically, that means continued investment in high-growth greenfields and capital projects with attractive return profiles. Inorganically, that means leveraging a fortified balance sheet to strengthen the portfolio via M&A in an approach I'd characterize as price-disciplined and value-creative. These avenues, I believe, represent our greatest growth opportunities and alongside solid execution can drive attractive returns for Summit shareholders."

2023 Guidance

For the full year 2023, Summit is raising its Adjusted EBITDA guidance to reflect performance over the first three months and improved outlook assumptions. The Company is now projecting Adjusted EBITDA of approximately $490 million to $530 million, up from the previous outlook of $480 million to $520 million. Summit currently projects 2023 capital expenditures of approximately $220 million to $240 million including greenfield projects.

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 2023 | Total Company Results

Net revenue increased $14.8 million, or 3.8% in the first quarter to $407.3 million, as increases in average sales prices across all lines of business more than offset lower volumes, which includes the impact of divestitures.

Operating loss decreased $18.8 million, or 54.9% in the first quarter to $15.5 million, driven by a combination of increases in average sales price that exceeded inflationary increases in cost of revenue and lower general and administrative expenses versus the prior year period. Summit's operating margin percentage for the three months ended April 1, 2023 increased to (3.8)% from (8.7)%, from the comparable period a year ago.

Net loss attributable to Summit Inc. decreased to $30.8 million, or $(0.26) per basic share, compared to $34.3 million, or $(0.28) per basic share in the comparable prior year period. Summit reported adjusted diluted net loss of $30.7 million, or $(0.26) per adjusted diluted share as compared to $40.4 million, or $(0.33) per adjusted diluted share in the prior year period.

Adjusted EBITDA increased $17.9 million, or 77.1% to $41.2 million primarily reflecting strong pricing across all lines of business.

First Quarter 2023 | Results by Line of Business

Aggregates Business: Aggregates net revenues increased by $20.3 million to $143.7 million in the first quarter. Aggregates adjusted cash gross profit margin decreased to 35.0% in the first quarter as compared to 36.3% in the prior year period. Aggregates sales volume decreased 6.2% in the first quarter due, in part, to divestitures in the East Segment. Organic aggregates sales volumes declined 3.4% due to unfavorable weather conditions and residential softness in the West Segment that more than offset organic aggregates volume growth from the East Segment. Average selling prices for aggregates increased 20.5%, the strongest quarterly growth rate in the Company's history. Growth was witnessed across all markets and led by the strongest gains in Texas and the Intermountain West.

Cement Business: Cement Segment net revenues increased 17.1% to $54.1 million in the first quarter. Cement Segment adjusted cash gross profit margin increased to 9.6% in the first quarter, compared to (2.0)% in the prior year period as strong pricing gains coupled with a greater contribution from Green America Recycling more than offset higher variable costs. Sales volume of cement decreased 1.2% reflecting, in part, lower import volume. Average selling prices increased 14.8% in the first quarter due to January pricing actions and the compounding impact from price increases implemented in 2022.

Products Business: Products net revenues were $179.5 million in the first quarter, compared to $189.7 million in the prior year period. Products adjusted cash gross profit margin increased to 12.4% in the first quarter, versus 11.6% in the prior year period. Organic average sales price for ready-mix concrete increased 15.3% driven by pricing growth across all markets, with strong, double-digit growth in Texas and the Intermountain West. Organic sales volumes of ready-mix concrete decreased 19.3% due to reduced residential activity. Organic average selling prices for asphalt increased 20.8%, due primarily to pricing gains in North Texas. Organic asphalt sales volume increased 38.7% with favorable weather conditions and public infrastructure demand particularly benefiting our North Texas market.

First Quarter 2023 | Results By Reporting Segment

West Segment: The West Segment operating income decreased $2.3 million to $5.7 million and Adjusted EBITDA of $32.7 million in the first quarter was comparable to the prior year period. Aggregates revenue increased 3.5% as 25.0% organic pricing growth was partially offset by 17.7% organic volume declines. Pricing growth was strongest in Texas and Salt Lake City and followed by more moderate growth in British Columbia. Ready-mix concrete revenue decreased 8.4% as 16.1% organic pricing growth was more than offset by lower volumes, particularly in Salt Lake City and, to a lesser extent, Houston. Asphalt revenue increased 74.7% due to organic pricing growth of 23.3% and organic volume growth of 37.9% driven predominately by the North Texas market.

East Segment: The East Segment operating income increased to $3.0 million and Adjusted EBITDA increased 131.7% to $18.9 million in the first quarter reflecting favorable pricing and demand conditions as well as benefiting from the timing of 2022 divestitures. Aggregates revenue increased 23.4% versus the prior year period. Organic aggregates volumes increased 18.1% driven, in part, by increased contribution from greenfields, strong growth in Kansas, and accommodating weather conditions. Aggregates pricing increased 13.2% with double-digit growth in the Carolinas and Missouri followed by high-single-digit growth in all other geographies. Ready-mix concrete revenue decreased 31.0% due primarily to divestitures and despite average selling price growth of 8.6% in the period. Due to divestitures, asphalt revenue decreased to $3.0 million.

Cement Segment: The Cement Segment operating loss decreased 41.2% to $7.9 million. Adjusted EBITDA increased $5.8 million as revenue growth combined with greater contribution from Green America Recycling to more than offset inflationary conditions. In the first quarter, the Cement Segment reported a volume decreased of 1.2% and average selling price growth of 14.8%.

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 Income, Adjusted Diluted EPS, Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Cash Gross Profit, Adjusted Cash Gross Profit Margin, Free Cash Flow, Net Leverage and Net Debt 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 Income, Adjusted Diluted EPS, Adjusted EBITDA, Further Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Cash Gross Profit, Adjusted Cash Gross Profit Margin, Free Cash Flow, Net Leverage and Net Debt 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 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, Further Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Cash Gross Profit, Adjusted Cash Gross Profit Margin, Adjusted Net Income (Loss), Adjusted Diluted Net Income, Adjusted Diluted EPS, Free Cash Flow, Net Leverage and Net Debt 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.
