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 third quarter 2021.

For the three months ended October 2, 2021, the Company reported net income attributable to Summit Inc. of $74.2 million, or $0.63 per basic share, compared to net income attributable to Summit Inc. of $90.7 million, or $0.79 per basic share in the comparable prior year period. The 18.2% decrease in net income included the reversal of an unrecognized tax benefit in 2020. Summit reported adjusted diluted net income of $81.5 million, or $0.68 per adjusted diluted share as compared to adjusted diluted net income of $63.9 million, or $0.55 per adjusted diluted share in the prior year period.

Summit's net revenue increased $17.0 million, or 2.6% in the third quarter of 2021 to $662.3 million, compared to $645.2 million in the third quarter of 2020, on higher aggregates, ready-mix concrete and cement revenue relative to a year ago on continued favorable market demand conditions and price growth in all lines of business.

The Company reported operating income of $125.0 million in the third quarter 2021, an increase of 24.3%, compared to $100.6 million in the prior year period, primarily due to higher revenue. General and administrative expenses also decreased by $3.6 million in the current period relative to third quarter 2020, when the Company incurred CEO transition costs. Summit's operating margin percentage for the three months ended October 2, 2021 increased to 18.9% from 15.6%, from the comparable period a year ago, due to the factors noted above.

Adjusted EBITDA increased in the third quarter 2021 to $190.3 million as compared to $177.3 million in the third quarter 2020.

For the three months ended October 2, 2021, sales volumes increased 9.2% in aggregates and 2.0% in cement relative to the same period last year on strong demand in most of our markets. Average selling prices in the third quarter of 2021 increased 3.9% in aggregates, 4.4% in cement, 3.7% in ready-mix concrete and 1.7% in asphalt. Adjusted cash gross profit for aggregates expanded to $96.7 million in the third quarter 2021, an increase of 26.1% relative to $76.7 million in the year ago quarter.

Anne Noonan, CEO of Summit Materials, commented, "The Market Leadership theme in our Elevate Summit strategy is beginning to be reflected in our results. Today we are reporting third quarter Adjusted EBITDA growth of 7.3% versus Q3 2020. Organic volume and pricing growth was reflected in expanded adjusted cash gross profit margin in aggregates, cement and services. Our Q3 Adjusted EBITDA margin increased 120 basis points from the year ago quarter, contributing towards our Elevate Summit 30% Adjusted EBITDA margin goal, which is measured over the trailing 12 months.

Summit is currently progressing several strategic divestitures in addition to the five divestitures that were already completed in the first half of 2021. We believe Summit's organic growth profile and asset light conversion model position the Company to absorb the impact of the foregone contribution from those divested businesses. When comparing 2020 to 2021, it’s also important to understand that 2020 included 53 reporting weeks, while 2021 is a standard 52-week reporting year. In consideration of factors such as those, we are leaving our full year 2021 Adjusted EBITDA guidance unchanged."

On September 27, 2021, Summit redeemed all $300.0 million of the 5.125% senior notes due June 1, 2025 using existing cash on hand. As a result of the redemption, charges of $6.0 million were recognized in the quarter ended October 2, 2021, which included charges of $3.9 million for the applicable redemption premium and $2.1 million for the write-off of the deferred financing fees.

As of October 2, 2021, the Company had $258.1 million in cash and $1.6 billion in debt outstanding. The Company's $345 million revolving credit facility has $329.1 million available after outstanding letters of credit. For the quarter ended October 2, 2021, cash flow provided by operations was $207.4 million and cash paid for capital expenditures was $170.1 million.

Brian Harris, CFO of Summit Materials, added, "Just a few months after the announcement of our Elevate Strategy, we have achieved our Elevate Summit leverage reduction goal of less than 3.0x, and we believe further improvements are possible with steady execution of our strategy."

For the full year 2021, Summit has not made any changes to its outlook for Adjusted EBITDA of approximately $490 million to $520 million, The Company continues to expect 2021 capital expenditure guidance of approximately $200 million to $220 million including approximately $25 million to $35 million for greenfield projects.

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. 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.
