Eliminates Up-C Structure

DENVER, March 13, 2024 /PRNewswire/ -- Summit Materials, Inc. (NYSE:SUM) ("Summit," "Summit Materials," "Summit Inc." or the "Company"), a market-leading construction materials company, announces highlights that are being presented at its Investor Day today in New York City.

"Since the introduction of our Elevate Summit Strategy in March 2021, it has been the cornerstone of our decision-making process, shaping our actions and providing a clear roadmap for our future," said Anne Noonan, CEO of Summit Materials. "Today, we are excited to share further insights into our strategic achievements and outline a detailed plan for reaching our Elevate Summit financial goals. We are confident in the attractiveness of the markets we operate in, the quality of our assets, and, importantly, our unique operational opportunities to drive profitable and sustainable growth, which, coupled with our ability to generate material synergies and our strong financial position, will drive ongoing growth and value creation for Summit shareholders."

Six key themes for today's presentation include:

Consistent Strategic Priorities: Enabled by our people and our culture, we maintain relentlessly focused on our four strategic priorities of Market Leadership, Asset Light, Sustainability, and Innovation.
Reaffirming our Path to Achieve Elevate Summit Financial Targets: Anchored by North Star profitability targets, an intentional shift towards a more materials-led organization, and an invest-to-grow mindset, we aim to maintain leverage below 3x, achieve ROIC of at least 10%, and reach Adjusted EBITDA margins of 30% or greater.
Recommitment to being the Most Socially Responsible: Our Sustainability Roadmap, which includes our goals for reducing carbon emissions, is deeply embedded in our organizational DNA. We are dedicated to benefiting communities and driving greater value through these initiatives.
Unlocking Value by Leveraging a Proven Integration Playbook: We'll rely on deep expertise and a long track record as we safely integrate Argos USA, fulfill synergy commitments, and enhance enterprise-wide profitability and cash flow.
Strengthening the Materials-led Portfolio: Ongoing portfolio optimization together with aggregates-oriented acquisitions will further our materials-led portfolio strategy.
Capital Allocation Priorities Aligned with Growth Objectives: Prioritizing above-market growth, our deployment of capital will be growth-oriented and directed towards the highest return opportunities.

"We are also pleased to announce the elimination of our Up-C corporate structure," added Summit CFO Scott Anderson. "By completing the exchange of all outstanding LP units, we have streamlined our structure significantly, reducing corporate complexity. We are focusing on eliminating the associated TRA liability in a value-accretive manner, as we have successfully done in the past."

Investors and other interested parties can watch the webcast of the event, which will begin at 9:00 a.m. ET today, at the Company's website, https://investors.summit-materials.com/corporate-profile/default.aspx. The event will be recorded and available for replay shortly after its conclusion.

2024 Guidance

For the full year 2024, Summit is reiterating all guidance items. The Company currently projects Adjusted EBITDA of approximately $950 million to $1,010 million, and continues to expect 2024 capital expenditure 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.

Investor Day Webcast Information

Summit Materials will conduct a conference call on Wednesday, March 13, 2024 beginning at 9:00am eastern time (7:00am mountain time).

Chief Executive Officer Anne Noonan and her executive leadership team will lead an investor presentation and Q&A session that will focus on the Elevate Summit Strategy, growth drivers, integration plans, ESG initiatives, as well as the Company's capital allocation priorities.

Non-GAAP Financial Measures

The Securities and Exchange Commission ("SEC") regulates the use of "non-GAAP financial measures," such as Adjusted EBITDA and Adjusted EBITDA margin, 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 EBITDA and Adjusted EBITDA margin 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 and Adjusted EBITDA margin 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.
