"Our fourth quarter caps a year of tremendous strategic progress. I am proud that, despite challenging macro conditions, in 2022 Summit Materials effectively completed our divestiture program, further fortified our balance sheet, set an Elevate Summit high water mark for ROIC, returned over $100 million to shareholders, and delivered record organic pricing growth across all lines of business," commented Anne Noonan, Summit Materials President and CEO. "Thanks to our team's dedicated focus on our Elevate Summit strategy we navigated dynamic market conditions and delivered admirable financial results consistent with the expectations we previously laid out. Achieving solid Adjusted EBITDA growth on a pro forma basis in the midst of historic cost inflation represents very strong operating performance and provides substantial momentum heading into 2023.

"More importantly, as we look to 2023, we strongly believe that the outlook we provide today is both achievable and appropriate given the level of uncertainty in the marketplace. We are well positioned and prepared to execute on the commercial and operational plans that are within our control with especially strong tailwinds from pricing expected in the year ahead. That said, cost trends and residential end market visibility are cause for a certain amount of managerial caution as we move into 2023. We believe we are taking a balanced, if not prudent, approach in setting expectation for next year and will leverage Summit's organizational agility to mitigate risk and capitalize on all market opportunities available to us."

Brian Harris, CFO of Summit Materials added, "The portfolio optimizing transactions we've completed since the launch of Elevate Summit together with a materials-led approach to M&A not only enhances our product mix and profitability, but also strengthens our balance sheet and the economic durability of our company. We continue to pursue a capital allocation approach that first prioritizes investments in high return organic and inorganic opportunities and then looks to opportunistically return capital to shareholders. This, coupled with sound operational execution, is a powerful combination to drive attractive shareholder value."

**2023 Guidance**

For the full year 2023, Summit is currently projecting Adjusted EBITDA of approximately $480 million to $520 million and expects 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.

------

**Full Year 2022 \| Total Company Results**

**Net revenue** decreased $10.6 million, or 0.5% in 2022 to $2.2 billion, as strong pricing growth across all lines of business nearly offset lower volumes and the impact of divestitures.

**Operating income** increased $16.0 million, or 6.3% in 2022 to $269.0 million, as higher revenue combined with lower depreciation, depletion, and amortization as well as lower general and administrative expenses more than offset higher cost of revenue. Summit's operating margin percentage for 2022 increased to 12.1% from 11.3% in 2021, due to the factors noted above.

**Net income attributable to Summit Inc.** increased to $272.1 million, or $2.27 per basic share, compared to $152.2 million, or $1.27 per basic share in the comparable prior year period. Summit reported adjusted diluted net income of $153.9 million, or $1.27 per adjusted diluted share as compared to $138.4 million, or $1.14 per adjusted diluted share in the prior year period.

**Adjusted EBITDA** decreased $28.6 million, or 5.5% to $491.5 million, primarily due to a decrease of $40.9 million from divestitures.

**Fourth Quarter 2022 \| Total Company Results**

**Net revenue** decreased $41.8 million, or 7.5% in the fourth quarter to $511.7 million, as increases in average sales prices across all lines of business were more than offset by lower volumes, which includes the impact of divestitures.

**Operating income** increased $7.9 million, or 13.7% in the fourth quarter to $65.0 million, due to lower depletion, amortization and accretion expenses as well as gains on the sale of property, plant and equipment. Summit's operating margin percentage for the three months ended December 31, 2022 increased to 12.7% from 10.3%, from the comparable period a year ago.

**Net income attributable to Summit Inc.** decreased to $29.8 million, or $0.25 per basic share, compared to $43.8 million, or $0.36 per basic share in the comparable prior year period. Summit reported adjusted diluted net income of $38.3 million, or $0.32 per adjusted diluted share as compared to $34.0 million, or $0.28 per adjusted diluted share in the prior year period.

**Adjusted EBITDA** decreased $5.0 million, or 4.0% to $119.3 million reflecting the impact of divestitures and inflationary cost of revenue conditions that more than offset pricing gains and lower general and administrative expenses relative to the prior year period. Excluding the impacts of acquisitions and divestitures, Adjusted EBITDA would have grown in the fourth quarter.

**Full Year 2022 \| Results by Line of Business**

**Aggregates Business:** Aggregates net revenues increased $10.8 million to $584.0 million in 2022. Aggregates adjusted cash gross profit margin decreased to 48.5% in 2022 as compared to 51.7% in 2021. Aggregates sales volume decreased 7.3% in 2022, primarily reflecting the impact of divestitures and unfavorable weather conditions. Excluding divestitures, organic sales volume decreased 2.8% in 2022. By market, volume performance was strongest in Virginia, Houston, and the Intermountain West. 2022 was a record pricing year as average selling prices for aggregates increased 8.2% fueled by 10.4% pricing growth in the West Segment and 7.3% pricing growth in the East Segment.

**Cement Business:** Cement Segment net revenues increased 20.0% to $357.7 million in 2022. Cement Segment adjusted cash gross profit margin of 39.6% in 2022 was relatively flat compared to 2021 adjusted cash gross profit margin of 39.9%. Sales volume of cement increased 4.2% and average selling prices increased 12.0% in 2022.

**Products Business:** Products net revenues decreased 4.8% in 2022. Products adjusted cash gross profit margin of 17.1% in 2022 decreased from 18.3% in 2021. Ready-mix concrete average selling prices increased 13.3% reflecting inflation-justified price increases and sales volumes decreased 13.5%, which includes the impact of divestitures. Ready-mix volumes in Houston and Salt Lake City, the Company's two primary residential markets, decreased 4.3% and 4.7%, respectively in 2022. Average selling prices for asphalt increased 19.0% with pricing growth across both reporting segments. Asphalt volume decreased 26.4% due to the divestiture of a paving business in 2021.

**Fourth Quarter 2022 \| Results by Line of Business**

**Aggregates Business:** Aggregates net revenues decreased by $6.4 million to $135.6 million in the fourth quarter. Aggregates adjusted cash gross profit margin increased to 47.8% in the fourth quarter as compared to 45.7% in the prior year period. Aggregates sales volume decreased 17.0% in the fourth quarter due primarily to divestitures in the East Segment. Organic

------

aggregates sales volumes declined 12.0% driven by a combination of unfavorable weather conditions, supply chain related disruptions, and moderating residential demand. Average selling prices for aggregates increased 13.9% in the fourth quarter with growth across all markets and led by the strongest gains in Texas, the Intermountain West, and the Carolinas.

**Cement Business:** Cement Segment net revenues increased 23.6% to $97.9 million in the fourth quarter. Cement Segment adjusted cash gross profit margin increased to 47.1% in the fourth quarter, compared to 42.7% in the prior year period as strong pricing gains more than offset higher variable costs and a greater proportion of sales from imports. Sales volume of cement increased 1.7% reflecting a healthy demand environment. Average selling prices increased 16.6% in the fourth quarter driven by compounding pricing actions taken in 2022 and an ongoing focus to improve customer mix.

**Products Business:** Products net revenues were $221.5 million in the fourth quarter, compared to $263.2 million in the prior year period. Products adjusted cash gross profit margin decreased to 17.1% in the fourth quarter, versus 18.3% in the prior year period. Organic average sales price for ready-mix concrete increased 20.7% 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 16.3% due to wet conditions, particularly in Texas and, to a lesser extent, moderating residential activity. Organic average selling prices for asphalt increased 19.3%, driven by strong pricing gains in North Texas and the Intermountain West. Organic asphalt sales volume decreased 12.3% as volume growth in the Intermountain West was more than offset by lower sales volumes in North Texas.

**Full Year 2022 \| Results By Reporting Segment** 

**West Segment:** The West Segment operating income increased 6.2% to $181.8 million and Adjusted EBITDA increased 3.3% to $280.6 million in 2022. Aggregates revenue in 2022 increased 9.0% driven by a 10.4% increase in average sales prices that was only partially offset by a 1.3% decrease in volume. Despite lower volumes in Texas and the Intermountain West, ready-mix concrete revenue in 2022 increased 9.5% with average sales price growth of 14.3% including double-digit pricing growth in Houston and Salt Lake City. Asphalt revenue increased by 3.7% as volumes decreased 10.2% due to a divestiture in the second quarter 2021 that was more than offset by 17.7% growth in average selling prices in 2022.

**East Segment:** The East Segment operating income decreased 28.6% to $64.6 million and Adjusted EBITDA decreased 28.8% to $129.2 million in 2022 due primarily to divestitures. Aggregates revenue decreased 7.1% despite 7.3% growth in average selling prices as volumes declined 13.4% due primarily to divestitures and unfavorable weather conditions. Ready-mix concrete revenue decreased 40.6% as volumes decreased by 44.1%, partially offset by average selling price growth of 6.4%. Asphalt revenue decreased 52.2% with volumes down 54.7% due to divestitures. Asphalt average selling prices increased 17.3% on higher liquid asphalt index prices across several markets.

**Cement Segment:** The Cement Segment operating income increased 34.8% to $89.2 million. Adjusted EBITDA increased 7.2% to $125.6 million in 2022 as demand conditions supported volume and pricing growth. The segment reported growth in sales volumes and average selling prices of 4.2% and 12.0%, respectively in 2022.

**Fourth Quarter 2022 \| Results By Reporting Segment** 

**West Segment:** The West Segment operating income increased 7.6% to $38.2 million and Adjusted EBITDA increased 8.5% to $64.9 million in the fourth quarter due primarily to pricing gains that more than offset lower volumes and inflationary cost conditions. Aggregates revenue in the fourth quarter increased 4.2% as 20.9% pricing growth was partially offset by 13.8% 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 in the fourth quarter increased 2.1% driven by 20.6% pricing growth and only partially offset by lower volumes, particularly in Houston. Lower aggregates and ready-mix volumes in Texas were due, in part, to wet weather conditions. Asphalt revenue increased 4.2% in the fourth quarter as sales prices increased 18.9% and volumes decreased 12.4% in the period.

**East Segment:** The East Segment operating income decreased 28.2% to $15.2 million and Adjusted EBITDA decreased 30.2% to $30.3 million in the fourth quarter reflecting the impact of divestitures. The impact from divestitures on Adjusted EBITDA was approximately $13.6 million in the period. Aggregates revenue decreased 13.4% versus the prior year period. Organic aggregates volumes decreased 9.8% driven, in part, by wet conditions in the Carolinas. Aggregates pricing increased 8.4% with double-digit growth in the Carolinas followed by high-single-digit growth in Northern Kansas, Missouri, and Virginia. Ready-mix concrete revenue decreased 50.8% due primarily to divestitures and despite average selling price growth of 10.4% in the period. Due to divestitures, asphalt revenue decreased 81.4%.

------

**Cement Segment:** The Cement Segment operating income increased 64.4% to $33.5 million in the fourth quarter. Adjusted EBITDA increased $6.7 million as revenue growth combined with greater contribution from Green America Recycling to more than offset inflationary conditions. In the fourth quarter, the Cement Segment reported a volume increase of 1.7% and average selling price growth of 16.6%.

**Liquidity and Capital Resources**

As of December 31, 2022, the Company had $520.5 million in cash and $1.5 billion in debt outstanding. The Company's $345 million revolving credit facility has $325.2 million available after outstanding letters of credit. In January 2023, the Company amended its senior secured revolving credit facility, increasing the total availability to $395 million and extending the maturity date to January 2028.

**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.

We derive many of our forward-looking statements from our operating budgets and forecasts, which are based upon many detailed assumptions.

Important factors could affect our results and could cause results to differ materially from those expressed in our forward-looking statements, including but not limited to the factors discussed in the section entitled "Risk Factors" in Summit Inc.'s Annual Report on Form 10-K for the fiscal year ended January 1, 2022, as filed with the SEC, and any factors discussed in the section entitled "Risk Factors" in any of our subsequently filed SEC filings.

 - the cyclical nature of our business;

 - risks related to weather and seasonality;

 - environmental, health, safety and climate change laws or governmental requirements or policies concerning zoning and land use;

 - rising prices for, or more limited availability of, commodities, labor and other production and delivery inputs as a result of inflation, supply chain challenges or otherwise;

 - conditions in the credit markets;

 - our ability to accurately estimate the overall risks, requirements or costs when we bid on or negotiate contracts that are ultimately awarded to us;

 - material costs and losses as a result of claims that our products do not meet regulatory requirements or contractual specifications;
