Notice of 2024 Annual Meeting of 

Stockholders, Proxy Statement  

& 2023 Annual Report

SAFETY ∙ INTEGRITY ∙ SUSTAINABILITY ∙ INCLUSIVITY  
LETTER FROM THE CHAIRMAN

To our valued stakeholders:

In  2023,  Summit  Materials’  Board  had  a  busy  and 
productive year as our Company delivered record financial 
performance  and  embarked  upon  the  transformational 
combination  with  Argos  USA  to  create  a  materials-led 
enterprise with national scale. Despite the significant effort 
involved  in  a  transformational  deal,  the  team  never  lost 
sight of its objectives, and Summit reported record annual 
net revenue and profitability, maintained a strong balance 
sheet,  and  allocated  capital  in  alignment  with  the  highest 
potential for growth and shareholder value creation.  

that 

the  Argos 

We  were  delighted 
transaction  was 
overwhelmingly  approved  by  an  over  98%  vote  of  our 
shareholders.  We believe that support reflects the strong 
strategic  and  financial  rationale  of  the  combination.  Our 
improved  geographic  diversification  will  enhance  our 
ability to meet customer demand for cement in a capacity-
constrained domestic market. 

Subsequent  to  the  transaction,  we  expanded  our  roster 
of  Independent  Directors.  Their  individual  strengths  and 
unique backgrounds together with a shared commitment to 
our mission and values will be invaluable as we integrate 
Argos USA into the Summit family and pursue our growth 
and return objectives.   Please join me in welcoming Jorge 
Mario Velasquez, Irene Moshouris, and Juan Esteban Calle 
Restrepo to the Summit Materials Board of Directors, who 
joined on January 12, 2024. Following these appointments, 
and together with the retirement of John Murphy, the Board 
consists of 11 directors, 10 of whom are independent.

I wish to thank John Murphy, who retired from the Summit 
Board after 12 years of service to the Company, including 
service  as  Chairman  of  the  Audit  Committee.    John’s 
disciplined counsel on capital allocation matters helped set 
the stage for Summit’s success. 

From  a  governance  perspective,  we  strive  to  balance 
agility with foresight, which are both essential for strategic 
execution.  Over the last three years, Summit has increased 
its Return on Invested Capital (ROIC) by 240 basis points 
and  increased  its  quality  of  earnings  with  a  17%  higher 
contribution  of  materials  to  its  financial  performance.    We 
continue  to  support  prudent  capital  allocation  decisions 
to  pursue  additional  growth 
that  maximize  flexibility 

in  aggregates.  Our  strong 
opportunities,  particularly 
balance sheet and manageable leverage profile prompted 
the recent credit rating upgrade to BB+ from S&P Global.

As a Board, we pride ourselves on upholding 
governance best practices. This includes: 

•  Separate Independent Chairman and Chief Executive 

Officer  

•  Fully Declassified Board (approved by shareholders 

in 2021) 

•  NYSE-Compliant Clawback Policy
• 
• 
•  Age diversity on the Board; short average tenure; no 

55% of Board Members are Female
90% of Directors are Independent

over-boarded directors

•  Amended Corporate Governance Guidelines and 

Governance and Sustainability Committee’s charter to 
formally adopt a policy to require any candidate pool 
assembled to fill a vacancy of the Board to include 
candidates who are diverse in terms of ethnicity and/
or gender

translate 

We  believe  that  operating  a  lower  cost,  lower  emission 
business  will 
into  sustainable  competitive 
advantage. We were recognized in that effort by receiving 
an ESG rating of “AAA” from MSCI for the second year in 
a  row,  placing  Summit  in  the  top  5%  of  global  issuers.  In 
addition  to  commending  our  use  of  alternative  fuels  and 
reduction in diesel consumption, the report noted, “Summit 
Materials leads most global peers in corporate governance 
practices.”

As  Chairman  of  the  Board,  I  sincerely  appreciate  the 
trust and faith you have instilled in us. Thank you for your 
continued support, and I hope you are as excited as I am 
about the opportunities ahead with the continued execution 
of our Elevate Strategy.

Sincerely,

HOWARD L. LANCE  
Chairman of the Board of Directors 
Summit Materials, Inc. 

 
LETTER FROM THE CEO

To our valued stakeholders:

In 2023, Summit Materials demonstrated the transformative 
power of our Elevate Strategy.  Our team achieved record 
financial performance with 18% EBITDA* growth and record 
adjusted  EBITDA  margins*.  We  continued  our  intentional 
shift  towards  high-margin  upstream  businesses.    We 
established a new high watermark for Return on Invested 
Capital  (ROIC)*  by  scrutinizing  every  asset  against  our 
return  and  margin  criteria.  Our  balance  sheet  continues 
to  reflect  a  disciplined  and  growth-oriented  approach  to 
capital allocation. 

With  the  addition  of  Argos  USA,  our  business  is  now 
materials-led  with  roughly  $8  out  of  every  $10  EBITDA* 
dollars  coming  from  either  aggregates  or  cement.    We 
are  building  significant  scale  in  our  industry  as  we  have 
become  the  largest  US-domiciled  cement  producer  and 
the  sixth  largest  aggregates  producer  in  the  US  with  a 
presence  in  many  high  growth,  year-around  construction 
markets.      Over  the  last  year  we’ve  continued  to  grow 
our  high  value  aggregates  position  as  we  entered  into 
the  high  growth  Phoenix  market  and  completed  several 
bolt-on  aggregates  acquisitions  in  targeted  geographies.  
Our  efforts  to  opportunistically  divest  subscale  assets 
in  non-strategic  markets  at  attractive  multiples  provides 
additional  dry  powder  for  future  aggregates  opportunities. 
The increased free cash flow conversion from larger scale 
cement  operations  will  accelerate  our  aggregates  growth 
ambitions.

Specifically, in 2023 we delivered:

•  Continued  focus  on  safety,  including  zero  recordable 

incidents in the East Region

•  Annual records for net revenue of $2.4 billion, adjusted 
gross profit of $757 million, and adjusted EBITDA* of 
$578  million,  up  10%,  17%,  and  18%,  respectively, 
versus the prior year

•  Double-digit pricing growth in all lines of business
• 

Improved  quality  of  earnings  with  ~80%  materials 
contribution to Adjusted EBITDA* 

•  A return on invested capital (ROIC)* of 10.4%, up from 

8% in 2020 

•  A low debt ratio at 2.1X net debt to Adjusted EBITDA* 

at year end, down from 3.2x in 2020

*This is a non-GAAP measure, please see the reconciliations at the back of this report.

integrity,  and 

The foundation of our success is rooted in our core values 
of  safety,  sustainability, 
inclusivity.  We 
expect  zero  harm  and  prioritize  the  health  and  well-being 
of our employees and our communities at the forefront of 
everything we do.   We achieved MSCI’s highest ESG rating 
of AAA for the second year in a row, improving our score 
from 2022 and placing us in the top 5% of global issuers. 

Our  efforts  to  align  and  engage  with  all  stakeholders, 
including  employees,  customers,  shareholders  and 
community members, are a source of pride and motivation.  
We extend our thanks to the teammates who deliver ready 
mix concrete to new factories and housing developments, 
who  pave  our  roads  as  part  of  a  construction  crew,  who 
operate  our  quarries,  our  cement  plants,  ready  mix  and 
asphalt  operations.    Summit  teammates  work  outdoors  in 
our communities, and they directly contribute to the growth 
of  our  economy.    They  embody  our  mission  to  lay  the 
foundation that connects our communities to build a better 
tomorrow.  

I  wish  to  thank  our  Board  of  Directors  for  their  counsel 
during a very busy and productive 2023. To our customers 
and  communities,  I  extend  my  sincere  gratitude  for  your 
commitment  and  support.  To  our  investors,  I  express  my 
appreciation for the resounding endorsement of the Argos 
transaction, which received over 98% approval. We do not 
take your support for granted and we continuously aim to 
earn your trust each and every day. 

Sincerely,

ANNE NOONAN
Chief Executive Officer  
Summit Materials, Inc.

operations that supply ready-mix concrete, asphalt, as well as paving services in select markets.

We are geographically diverse, materials-led business of scale that offers customers in the United
States and British Columbia, Canada high quality products and services for the public
infrastructure, residential and non-residential end markets. Our operations benefit from Summit’s
access to capital, IT resources, performance optimization practices and a highly-experienced
management team. We believe this model allows us to realize the benefits of locally invested
operators with the expertise and economies of scale of a larger entity.

We provided approximately 5,300 jobs in 2023, and we believe our people are our greatest
asset. We support our employees with:

•

•

•

•

Health and wellness programs

Training and development programs with broad participation throughout all levels of the Company

An excellent safety track record

At Summit, we recognize that robust environmental and social performance is not only the right thing to do but that it is
key to achieving our vision to be the most socially responsible integrated construction materials solution provider. To
guide us to our vision, our North Star principles were developed through a company-wide strategic assessment. Those
principles include:

○

○

Human / Social Impact: Ensuring people and their communities are valued and can thrive.

We have established both 2030 and 2050 targets for each of the North Star Pillars. Target setting was completed
hand-in-hand with the development of our Elevate strategy. We embedded ESG targets in the planning process to
ensure business decisions are made with sustainability considerations in mind. Further details for each target are
found within our 2023 ESG Report.

We completed a qualitative climate risk assessment to support our enterprise risk process and to identify potential
impacts of climate-related risks. We also completed a quantitative scenario modeling across our operations to
assess our portfolio’s resilience under different external conditions. Scenario analysis is a critical tool for strategic
planning, risk management and assessing our strategic resilience.

OUR BOARD OF DIRECTORS

ITEM 1
ELECTION OF DIRECTORS

The board of directors (the ‘‘Board’’) of Summit Materials, Inc. (‘‘Summit Materials’’ or the ‘‘Company’’) currently has eleven seats.
Our directors are Juan Esteban Calle, Joseph S. Cantie, Anne M. Cooney, Susan A. Ellerbusch, Howard L. Lance, Irene Moshouris,
Anne P. Noonan, Tamla D. Oates-Forney, Jorge Mario Velásquez, Anne K. Wade, and Steven H. Wunning, and each of their terms
will expire at this Annual Meeting.

At the Company’s 2021 Annual Meeting, the Company’s stockholders approved and adopted an amendment to the Company’s
amended and restated Certificate of Incorporation (the ‘‘Charter’’) to remove the three separate classes of directors of the Board
and replace with one class of directors (the ‘‘Declassification Amendment’’). As a result, all of the directors are up for election at the
2024 Annual Meeting to serve for a term of one year, and all directors will be elected to serve for one year terms at all subsequent
Annual Meetings.

Accordingly, the Board proposes that Mss. Cooney, Ellerbusch, Moshouris, Noonan, Oates-Forney, Wade, and Messrs. Calle,
Cantie, Lance, Velásquez, and Wunning be reelected to the Board for a one-year term expiring at the 2025 Annual Meeting. Each
nominee for director will, if elected, continue in office until the 2025 Annual Meeting and until the director’s successor has been duly
elected and qualified, or until the earlier of the director’s death, resignation or removal.

The proxy holders named on the proxy card intend to vote the proxy (if you are a stockholder of record) for the election of each of
these nominees, unless you indicate on the proxy card that your vote should be withheld for any of the nominees. Under Securities
and Exchange Commission (‘‘SEC’’) rules, proxies cannot be voted for a greater number of persons than the number of nominees

Board Organization

Good corporate governance at Summit Materials starts at the top—with how we, as the Board, are governed. We believe our board
governance incorporates best-practice standards as appropriate for our Company:

• We have an independent board Chairman

•

•

•

All members of our committees are independent

All of our non-employee directors are independent

All directors may request that items be added to the Board’s agenda or the agenda of any committee on which they serve

At the Board’s recommendation, at the Company’s 2021 Annual Meeting, the Company’s stockholders approved and
adopted the Declassification Amendment. Accordingly, all eleven directors will be elected at the 2024 Annual Meeting to
serve for a term of one year, and all directors will be elected to serve for one year terms at all subsequent Annual
Meetings.

Director Independence Determination

Under our Corporate Governance Guidelines and the NYSE corporate governance rules for listed companies, a director is not
independent unless the Board affirmatively determines that he or she does not have a direct or indirect material relationship with us
or any of our subsidiaries. In addition, the director must meet the bright-line test for independence set forth by the NYSE rules. Our
Corporate Governance Guidelines define independence in accordance with the independence definition in the current NYSE rules.
Our Corporate Governance Guidelines require the Board to review the independence of all directors at least annually. In the event
a director has a relationship with the Company that is relevant to his or her independence and is not addressed by the objective
tests set forth in the NYSE independence definition, the Board will determine, considering all relevant facts and circumstances,
whether such relationship is material.

Our Board has affirmatively determined that each of Mss. Cooney, Ellerbusch, Moshouris, Oates-Forney, Wade, and Messrs. Calle,
Cantie, Lance, Velásquez, and Wunning is independent, under the guidelines for director independence set forth in the Corporate
Governance Guidelines and under all applicable NYSE rules, including with respect to applicable committee membership. Our
Board also has determined that (i) each of the members of the Audit Committee, Mss. Ellerbusch, Moshouris, and Wade and
Mr. Cantie, is ‘‘independent’’ for purposes of Section 10A(m)(3) of the Securities Exchange Act of 1934, as amended (the
‘‘Exchange Act’’), and ‘‘financially literate’’ as required by NYSE rules and (ii) each of Mr. Cantie and Ms. Moshouris qualify as a
‘‘financial expert’’ as defined by SEC regulations.

In making its independence and financial literacy determinations, the Board considered and reviewed all information known to it,
including information identified through annual directors’ questionnaires.

Board Leadership

The Board directs and oversees the management of the business and affairs of the Company in a manner consistent with the best
interests of the Company. The Board’s responsibility is one of oversight, and in performing its oversight role, the Board serves as
the ultimate decision-making body of the Company, except for those matters reserved to or shared with our stockholders.

In accordance with the Company’s belief that its long-term success includes being good stewards of the environment, the Board
oversees and supports the Company’s initiatives in these areas. In addition, the Board takes pride in supporting the Company’s
efforts to offer a safe work environment to its employees and being a good corporate citizen in its local communities.

In accordance with our Corporate Governance Guidelines, the Board selects the Company’s Chairman and the Company’s Chief
Executive Officer in any way it considers in the best interests of the Company, and it does not have a policy on whether the roles of
Chairman and Chief Executive Officer should be separate or combined and, if separate, whether the Chairman should be selected
from the independent directors. We believe that the separation of the Chairman of the Board and Chief Executive Officer positions
is appropriate corporate governance for us as this time. Accordingly, Mr. Lance serves as the Chairman of the Board while
Ms. Noonan serves as our Chief Executive Officer. Our Board believes that this structure best encourages the free and open
dialogue of differing views and provides for strong checks and balances.

Corporate Governance Documents

Our investor relations website at investors.summit-materials.com/govdocs, ‘‘Governance Documents,’’ has additional information
on our board governance and corporate governance, including our Corporate Governance Guidelines, our Code of Business
Conduct and Ethics, our Whistleblower Policy, and the charters approved by the Board for the Audit Committee, the Human Capital
and Compensation Committee, and the Governance and Sustainability Committee.

Board Meetings and Committees

The Board meets regularly during the year and holds special meetings and acts by unanimous written consent when circumstances
require. During 2023, there were 11 meetings of the Board. Each director attended at least 75% of the aggregate of the total
number of meetings of the Board (held during the period for which he or she was a director) and the total number of meetings held
by all committees on which he or she served (during the periods that he or she served) during 2023. In addition, directors are
expected to make every effort to attend any meetings of stockholders. All of our directors who were serving at the time of the 2023
Annual Meeting of Stockholders attended the meeting.

The Board has established an Audit Committee, a Human Capital and Compensation Committee, and a Governance and
Sustainability Committee (collectively, the ‘‘Committees’’). The Committees keep the Board informed of their actions and assist the
Board in fulfilling its oversight responsibility to stockholders. The table below provides current membership information as well as
meeting information for the last fiscal year.

Governance and Sustainability Committee

Our Governance and Sustainability Committee consists of Mss. Cooney and Ellerbusch and Messrs. Velásquez, and Wunning, with
Ms. Cooney serving as chair.

Our Governance and Sustainability Committee is responsible for, among other things:

•

•

•

•

•

•

•

•

assisting our Board in identifying prospective director nominees and recommending nominees to the Board;

overseeing the annual evaluation of management;

overseeing the annual evaluation of the Board in conjunction with our Chairman’s regular informal interviews with our

reviewing and advising the Board on developments in corporate governance practices;

reviewing and recommending the compensation of our directors;

developing and recommending a set of corporate governance guidelines;

recommending members for each committee of our Board; and

overseeing the Company’s approach to social responsibility and policies and initiatives related thereto.

Director Nominations

The Governance and Sustainability Committee identifies individuals believed to be qualified as candidates to serve on the
Board and selects, or recommends that the Board select, the nominees for all directorships to be filled by the Board or by our
stockholders at an annual or special meeting.

In identifying candidates for membership on the Board, the Committee takes into account all factors it considers appropriate, which
may include:

•

•

individual qualifications, including strength of character, mature judgment, familiarity with the Company’s business and
industry, independence of thought and an ability to work collegially; and

all other factors the Committee considers appropriate, which may include age, diversity of background, existing
commitments to other businesses, potential conflicts of interest with other pursuits, legal considerations such as antitrust
issues, corporate governance background, relevant career experience, relevant technical skills, relevant business or
government acumen, financial and accounting background, executive compensation background and the size,
composition and combined expertise of the existing Board.

In 2022, the Company amended its Corporate Governance Guidelines and Governance and Sustainability Committee’s charter and
formally adopted a policy to require any candidate pool assembled to fill a vacancy of the Board to include candidates who are
diverse in terms of ethnicity and/or gender. The Board is proud of the gender diversity it has been able to accomplish over the last
few years, which has resulted in the Board being comprised of 55% females and 45% males. In addition, the Board made strides in
other forms of diversity, including racial and ethnic diversity, in connection with the appointment of Ms. Oates-Forney, who identifies
as African American in 2021 and the addition of Messrs. Esteban and Velásquez, each of whom identifies as Hispanic.

The Committee also may consider the extent to which the candidate would fill a present need on the Board. When evaluating
whether to re-nominate existing directors, the Committee considers matters relating to the retirement of current directors, as well as
the performance of such directors.

The Governance and Sustainability Committee evaluates director candidates recommended by stockholders on the same basis as
it considers other nominees. Any recommendation submitted to the Chief Legal Officer and Secretary should be in writing and
should include any supporting material the stockholder considers appropriate in support of that recommendation, but must include
information that would be required under the rules of the SEC to be included in a proxy statement soliciting proxies for the election
of such candidate and the written consent of the candidate to serve as one of our directors, if elected. Stockholders wishing to
propose a candidate for consideration may do so by submitting the above information to the attention of the Chief Legal Officer and
Secretary, Summit Materials, Inc., 1801 California Street, Suite 3500, Denver, Colorado 80202. All recommendations for
nomination received by the Chief Legal Officer and Secretary that satisfy the requirements of our Third Amended and Restated
Bylaws (the ‘‘Bylaws’’) relating to such director nominations will be presented to the Governance and Sustainability Committee for
its consideration. Please see the section entitled ‘‘Future Shareholder Proposals and Nominations’’ for information regarding the
advance notice provisions applicable to stockholder director nominations set forth in our Bylaws.

The Board believes that the practices it follows and the guidelines it adopts governing how it operates set an important tone at the
top. Among other things the Board:

•

•

•

•

•

•

•

meets regularly;

meets periodically in executive session of its independent directors;

has the authority to retain independent advisors;

enables directors to have access to management;

limits the number of public company boards on which directors may serve;

expects its members as well as the Company’s executives to satisfy the stock ownership guidelines; and

prohibits its members and the Company’s executives from taking specified hedging and pledging actions with the
Company’s stock.

Executive Sessions and Communications with Directors

The Board’s independent directors meet at regularly scheduled executive sessions without management present. Mr. Lance
presides at executive sessions of independent directors.

Stockholders and other interested parties may communicate with the Board by writing to the Chief Legal Officer and Secretary,
Summit Materials, Inc., 1801 California Street, Suite 3500, Denver, Colorado 80202. Written communications may be addressed to
the Chairman of the Board, the chairperson of any of the Audit, Governance and Sustainability, and Human Capital and
Compensation Committees, or to the non-management or independent directors as a group. The Chief Legal Officer will forward
such communications to the party determined to be appropriate for delivery. Materials that may not be forwarded include junk mail
and items that do not pertain to board matters.

Risk Oversight

The Board exercises direct oversight of strategic risks to the Company. The Audit Committee reviews guidelines and policies
governing the process by which senior management assesses and manages the Company’s exposure to risk, including the
Company’s major financial and operational risk exposures and the steps management takes to monitor and control such
exposures. The Human Capital and Compensation Committee oversees risks relating to the Company’s compensation and human
capital management policies and practices. Each committee charged with risk oversight reports to the Board on those matters.

Cybersecurity

As part of our enterprise risk management function, we have implemented processes to assess, identify and manage the material
risks facing the Company, including from cyber threats. Our enterprise risk management function represents our overall risk
management system. Our cybersecurity program is built upon recognized security frameworks. We believe that our processes
provide us with a comprehensive assessment of potential cyber threats. We conduct regular scans, penetration tests, and
vulnerability assessments to identify any potential threats or vulnerabilities in our systems. Our processes to assess, identify and
manage the material risks from cyber threats include the risks arising from threats associated with third party service providers,
including cloud-based platforms.

We have developed a cyber incident response plan which provides a documented framework for handling security incidents and
facilitates coordination across multiple parts of the company. Dedicated members of our information security team, led by our
Vice President, Infrastructure, constantly monitor threat intelligence feeds, handles vulnerability management and responds to
incidents. In addition, we periodically perform simulations and drills at both a technical and management level.

Internally, we have a security awareness training platform which includes training that reinforces our information technology and security
policies, standards and practices, and we require that our employees comply with these policies. The security awareness training
platform offers training on how to identify potential cybersecurity risks and protect our resources and information. This training is
mandatory for all employees on a periodic basis, and it is supplemented by testing initiatives, including periodic phishing tests.

18 | SUMMIT MATERIALS 2024 NOTICE OF ANNUAL MEETING AND PROXY STATEMENT

From time to time, we engage third-party service providers to enhance our risk mitigation efforts. For instance, we have engaged
an independent cybersecurity advisor to lead a cybersecurity crisis simulation exercise that has been used by our senior leaders to
prepare for a possible cyber crisis. We have also partnered with an industry expert’s incident response group to help deconstruct,
manage and mitigate impact from any cyber-related incident. We also purchase insurance to help protect us against the risk of
cybersecurity breaches.

To date, we have not had a significant cybersecurity breach or attack that has had a material impact on our business or results of
operations.

Our Board of Directors exercises direct oversight of our strategic risks through its oversight of our enterprise risk management
function. The Audit Committee of the Board of Directors in particular is responsible for reviewing our IT security controls and the
adequacy of our IT security program, compliance and controls with management. As part of such oversight, the Board of Directors,
including members of the Audit Committee, receives periodic reports from our Chief Information Officer and Vice President,
Infrastructure to assess the primary cybersecurity risks we face. Our Chief Accounting Officer reports directly to the Board of
Directors on our company-wide enterprise risk management, which includes an evaluation of cyber risks and threats. Our Chief
Information Officer, together with our Vice President, Infrastructure, is responsible for the day-to-day management of our
cybersecurity risks.

ESG Oversight

The Company recognizes that ESG performance is essential to the Company’s long-term success and is an important issue to
many of its stockholders. As a result, the Company has implemented the following oversight structure to ensure that the Company’s
performance in these areas is monitored appropriately:

ESG OVERSIGHT

BOARD OF D IRECTORS

Audit Committee

Governance & Sustainability
Committee

Human Capital &
Compensation Committee

SENIOR LEADERSHIP TEAM & ERC

Finance, Legal, H.R., & I.R.

Sustainability Council

Operations Management

(Through EMS)

In light of the importance of environmental and climate change matters to the Company, its shareholders, communities, customers,
and employees, and the associated risks the Company faces, the full Board oversees environmental risk factors and receives
regular updates from management and the Company’s sustainability team on the Company’s environmental risk profile and key
risk mitigating initiatives. The Company’s management functions involved in overseeing and managing climate risk include, but are
not limited to, safety, sustainability, finance and internal audit, and legal. Furthermore, each of the Company’s operations has
personnel responsible for maintaining compliance with environmental rules and regulations.

In addition, the Company views sustainability as one of its core values and takes its responsibilities to the lands it operates on
seriously. The Company has a dedicated Enterprise Risk Committee (the ‘‘ERC’’) that continually identifies and evaluates
environmental and other risks, including the Company’s compliance with environmental rules and regulations. The ERC reports to
the full Board. The ERC undertakes regular, systematized review of the environmental risks affecting the Company, including those
associated with climate change, that may affect the Company’s businesses and also meets with key leaders in the Company’s
operations to identify and address such risks.

The Company has an Environmental Management System (the ‘‘EMS’’) called eVue to facilitate its ongoing compliance with
environmental rules and regulations across many of its operations.

With respect to abnormal weather and other physical effects of climate change, to which, as an outdoor business, the Company is
acutely attuned, the Company is seeking to monitor and reduce its contribution to climate change. The Company’s efforts include,
but are not limited to, the following:

•

•

•

•

•

•

•

•

•

•

•

Establishing clear 2030 and 2050 targets for carbon emissions reductions, including a strategy for achieving net zero
emissions by 2050, land use improvement, and social impact;

Reporting on its sustainability progress annually under the SASB Construction Materials Framework;

Preliminary efforts towards a climate risk assessment of potential transition and physical risks;

Aligning with the United Nations Sustainable Development Goals to guide and influence the Company’s programs and
reporting;

Recycling of hazardous waste, and use of such waste as an alternative fuel source to power the Company’s cement plants;

Use of hybrid vehicles and equipment;

Use of recycled materials, including recycled asphalt and recycled concrete;

Managing and tracking the Company’s fleet to optimize fuel efficiency and reduce unnecessary consumption;

Managing and mitigating the Company’s waste;

Promoting progressive reclamation and biodiversity focused actions; and

Tracking and managing the Company’s water use, with a focus on areas of water scarcity.

The Company also continues to comprehensively focus on its energy inputs, CO2 and other pollutant emissions from its cement
plants. From an energy use standpoint, the Company’s alternative fuel usage rate of 38.2% at its cement plants is notable in
comparison to the average U.S. industry rate of 25% as reported by the U.S. Environmental Protection Agency in 2008. The
Company has made advancements in recent years to (i) accept more diverse materials at its hazardous waste recycling business,
(ii) increase its alternative fuel use, and (iii) divert thousands of pounds of waste from landfills. The Company has also developed a
long-term strategy to address its CO2 emissions from its cement operations that are fully discussed in its 2023 sustainability report.

With respect to emissions impacts, in 2021 the Company completed a comprehensive review of the Company’s greenhouse gas
(‘‘GHG’’) emissions reporting capabilities across all of the Company’s operations for 2020. This assessment focused on Scope 1
and Scope 2 emissions, which represent emissions from direct operations and indirect electricity purchases, respectively. In
addition, in 2022, the Company completed a climate physical and transition risk scenario analysis. This high level, qualitative
climate risk assessment was informed by the Task Force on Climate-related Financial Disclosures (‘‘TCFD’’) recommendations and
makes reference to third party scenarios, such as the International Energy Agency’s (‘‘IEA’’) Sustainability Development-Scenarios.

Now that the Company has implemented the appropriate reporting framework and controls, the Company has been able to
establish goals related to emissions and other factors contributing to climate change. As the Company systematizes its approach to
mitigating its climate impact, it will continue to pursue and expand upon the beneficial initiatives it is already implementing, such as
the use of hybrid vehicles, a robust recycling and waste program, and sourcing alternative fuels to power its operations. In 2023,
the Company conducted a company-wide fleet electrification study. This study analyzed the feasibility, costs and benefits of
transitioning the fleet to electric vehicles. The findings of this study informed future decision-making around fleet electrification.

The Company also seeks to carry out progressive reclamation whenever possible, and it believes in the protection and restoration
of areas of high biodiversity value. In 2014, the Company established a partnership with the Wildlife Habitat Council (‘‘WHC’’). We
currently have eight sites certified by the WHC, covering approximately 2,300 acres across the country. As of 2023, Summit has
been awarded 3 Gold Tier WHC certifications. We remain focused on exploring new, innovative ways in which the Company can
meaningfully reduce the environmental impact where we operate and are wholly in support of achieving carbon neutrality by 2050.

Finally, the Company values the communities in which it operates and offers engagement through STEM education programs to
enhance local education programs, encourage transparency and outreach.

Code of Ethics

The Company’s Code of Business Conduct and Ethics applies to all of its officers, directors and employees, including its principal
executive officer, principal financial officer and principal accounting officer, or persons performing similar functions and is posted on
our website. The Company’s Code of Business Conduct and Ethics is a ‘‘code of ethics,’’ as defined in Item 406(b) of Regulation
S-K. The Company will make any legally required disclosures regarding amendments to, or waivers of, provisions of our Code of
Business Conduct and Ethics on its website.

Director Compensation

In 2023, all of the Company’s non-employee directors received annual cash compensation of $110,000. The independent chairperson
of the Board received an additional $140,000 cash compensation. The respective chairpersons of the Audit Committee, Human
Capital and Compensation Committee and Governance and Sustainability Committee (unless such chairperson is also the
chairperson of the Board) received an additional $25,000, $20,000 and $15,000, respectively. Directors who were not employed by us
may also receive compensation, from time to time, for service on any special committees of the Board. The Company reimburses its
directors for any reasonable expenses incurred by them in connection with services provided in such capacity.

In addition, during 2023, all of the Company’s non-employee directors received an annual award of restricted stock units (‘‘RSUs’’)
valued at $130,000 based on the closing price of the Company’s common stock for the twenty trading days immediately preceding
the grant date, which amount differs from the grant date fair value of the RSUs computed in accordance with ASC 718, utilizing the
assumptions discussed in Note 13, Stock-Based Compensation, to our audited consolidated financial statements included in the
2023 Annual Report. A grant of 4,038 RSUs was made to each of Messrs. Lance, Cantie, Murphy, and Wunning and Mss. Cooney,
Ellerbusch, Oates-Forney, and Wade on February 22, 2023. The RSUs were granted under the Summit Materials, Inc. Amended
and Restated 2015 Omnibus Incentive Plan (the ‘‘Omnibus Incentive Plan’’), and the terms thereof are outlined in the table below.
Further, the RSU awards are subject to the Company’s Incentive Compensation Clawback Policy.

Aon’s Human Capital Solutions Practice, a division of Aon plc (‘‘Aon’’), the Company’s independent compensation consultant
(the ‘‘Independent Compensation Consultant’’), performs a comprehensive competitive total compensation review for the
Company’s non-employee directors regularly. A competitive total compensation study was performed in November 2020,
comparing the Company’s total compensation structure and value to peer companies. The Company is currently competitively
positioned. In the years the Independent Compensation Consultant does not perform a comprehensive review, they review broader
U.S. market trends with the Human Capital and Compensation Committee.

The amounts reported in the Stock Awards column reflect the aggregate grant date fair value of RSUs granted in fiscal 2023, computed in accordance with
ASC 718, utilizing the assumptions discussed in Note 13, Stock-Based Compensation, to our audited consolidated financial statements included in the 2023
Annual Report. As of December 31, 2023, each of our non-employee directors held 4,038 RSUs. As noted above, our targeted equity value is $130,000 annually.
The value in this column does not necessarily match the $130,000 target because we calculate the number of RSUs to grant based on the 20-day average closing
stock price ($32.19) immediately preceding the grant date in order to mitigate the potential impact of short-term stock price swings on our equity grants.

(2) We did not make any option awards to directors in fiscal 2023. As of December 31, 2023, Messrs. Lance and Murphy held 81,611 and 10,220 time-vesting

Leverage Restoration Options, respectively. Time-vesting Leverage Restoration Options held by our directors have the same vesting terms as those held by our
NEOs and described in ‘‘Narrative Disclosure to Summary Compensation Table and Grants of Plan-Based Awards Table—Pre-IPO Long-Term Incentive Awards
(Value From Modifications to Eliminate Misalignment Post-IPO).’’

Upon the consummation of the Argos Transaction, Mr. Murphy retired from the Board.

ITEM 2
NONBINDING ADVISORY VOTE ON THE
COMPENSATION OF OUR NEOs

Under the Dodd-Frank Wall Street Reform Consumer Protection Act (the ‘‘Dodd-Frank Act’’) and Section 14A of the Exchange Act,
our stockholders are entitled to vote to approve, on a nonbinding advisory basis, the compensation of our NEOs, as disclosed in
this Proxy Statement in accordance with SEC rules. The compensation of our NEOs subject to the vote is disclosed in the
Compensation Discussion and Analysis, the compensation tables, and the related narrative disclosure contained in this Proxy
Statement. The compensation of our NEOs is designed to enable us to attract and retain talented and experienced executives to
lead us successfully in a competitive environment, while ensuring that our executives remain incentivized to accomplish the
Company’s long-term business plan. As discussed in this Proxy Statement, the vast majority of each NEO’s pay is at-risk and
largely tied to challenging performance goals. We believe that our compensation policies and decisions are strongly aligned with
our stockholders’ interests.

The Board is asking our stockholders to indicate their support for the compensation of our NEOs as disclosed in this Proxy
Statement by casting a nonbinding advisory vote ‘‘FOR’’ the following resolution:

‘‘RESOLVED, that the compensation paid to our NEOs, as disclosed pursuant to Item 402 of Regulation S-K, including the
Compensation Discussion and Analysis, compensation tables, and narrative disclosure, is hereby APPROVED.’’

Because the vote to approve the compensation of our NEOs is advisory, it is not binding on the Board or the Company.
Nevertheless, the views expressed by our stockholders, whether through this vote or otherwise, are important to management and
the Board and, accordingly, the Board and the Human Capital and Compensation Committee intend to consider the results of this
vote in making determinations in the future regarding executive compensation arrangements, as a part of its robust compensation
review and assessment process. Nonbinding advisory approval of this proposal requires the vote of the holders of a majority of the
voting power of the shares present in person or represented by proxy and entitled to vote on the matter at the Annual Meeting.

THE BOARD RECOMMENDS A VOTE ‘‘FOR’’ THE APPROVAL,
ON A NONBINDING ADVISORY BASIS, OF THE COMPENSATION
OF OUR NEOs, AS DISCLOSED IN THIS PROXY STATEMENT

2023 Financial Highlights

The Company launched its Elevate Summit strategy in March 2021. Elevate Summit has multiple aspects and horizons:

•

•

•

•

become the market leader in advantaged exurban & markets where we invest and grow for a #1 or #2 market position;

utilize asset light partnerships to maximize the pull through and reduce volatility in select markets while enhancing
EBITDA margin and return on invested capital (‘‘ROIC’’);

become the most socially responsible integrated construction materials solution provider; and

develop innovative solutions to address tomorrow’s challenges.

Within these key themes, we specifically targeted a reduction in leverage below 3X EBITDA, increase in margins and optimization
of our portfolio.

This allowed the Company to achieve the following in 2023:

•

•

•

Strong net revenue gains across lines of business and led by organic growth in Aggregates and Asphalt

Average selling prices increased across all three reporting Segments

Net income attributable to Summit of $285.9 million, adjusted cash gross profit of $757.1 million, adjusted EBITDA of
$578.0 million and free cash flow of $197.7 million*

• We prioritized sustainable growth by investing in profit improving capital expenditures while advancing strategic

divestitures that enhance our market-leading positions, and acquiring new businesses in targeted, strategic markets

•

Reduced our leverage ratio to 2.1x Net Debt to Adjusted EBITDA* at year end 2023, matching the lowest debt ratio in the
Company’s history

*

Adjusted cash gross profit, adjusted EBITDA, free cash flow, and Net Debt to Adjusted EBITDA are non-GAAP financial
measures; see ‘‘Reconciliation of Non-GAAP Measures to GAAP’’ on Annex A.

Pay Mix and Magnitude

The Human Capital and Compensation Committee believes that a significant majority of both the Chief Executive Officer’s and
other NEOs’ pay should be at risk and not guaranteed. Compensation is tied to challenging performance objectives and this is
illustrated in our pay mix. A large percentage of total target compensation is at risk through long-term equity awards and annual
cash incentive awards. These awards are linked to performance measures that correlate with long-term stockholder value creation.
The amounts actually realized by our NEOs with respect to these awards depend on a variety of factors, including the level of
attainment of the relevant performance goals and the extent of vesting of performance units and RSUs and the value of our stock
when performance units and RSUs vest.

The target values of long-term equity incentive awards used in the charts below differ from the compensation reported in the
Summary Compensation Table due to the use of the grant date fair value in the Summary Compensation Table which is calculated
in accordance with ASC 718, utilizing the assumptions discussed in our audited consolidated financial statements included in the
2023 Annual Report. The mix of total direct compensation at target for 2023 for our Chief Executive Officer and the average of our
other NEOs (excluding Mr. Harris) is shown in the charts below.

Elements of Pay: Base Salary

The Human Capital and Compensation Committee determines base salaries for the NEOs and other executives based on a
number of factors, including but not limited to, the Human Capital and Compensation Committee’s understanding of executive pay
practices, individual performance, Company performance and management recommendations (except with respect to the Chief
Executive Officer).

The base salary increases for Ms. Noonan was 4%, Mr. Anderson was 30%, Mr. Gaskill was 10%, and Mr. Ghelani was 3.5%.
Ms. Anderson’s and Mr. Harris’ base salaries were unchanged from 2022.

increased in order to reflect a competitive base salary for similar roles. Mr. Anderson’s base salary was increased in connection
with his promotion to Executive Vice President and Chief Financial Officer. These base salaries reflect a thorough review of
competitive market data, internal alignment of total compensation opportunity, and are consistent with competitive market data
provided by the Independent Compensation Consultant.

Elements of Pay: Annual Cash Incentives

2023 TARGET ANNUAL INCENTIVE AWARD OPPORTUNITIES

At the start of each fiscal year, the Board approves annual incentive compensation targets, as a percentage of target base salary,
based on competitive market data provided by the Independent Compensation Consultant for our direct competitors and overall
peer group, management’s recommendations and other relevant factors. The 2023 annual incentive targets, as a percentage of
target base salary, for our NEOs were unchanged from 2022 for Ms. Noonan, Mr. Ghelani, and Mr. Harris. Mr. Anderson whose first
day of employment as Executive Vice President and Chief Financial Officer was March 1, 2023 increased from 60% to 75% in
connection with his promotion and Ms. Anderson and Mr. Gaskill increased to 65% effective March 26, 2023.

2023 ANNUAL INCENTIVE METRICS

The metrics underlying our annual incentive were selected as the strongest indicators of our success. Adjusted EBITDA and
EBITDA Margin are among our most important financial measures, while safety goals ensure that we focus on sustainable
performance. The Board has discretion to adjust the target financial metrics to reflect, among other things, mergers, acquisitions,
divestitures and other non-routine activity both inside and outside of management’s control during the fiscal year.

2024 NOTICE OF ANNUAL MEETING AND PROXY STATEMENT SUMMIT MATERIALS | 29

For 2023, we modified our performance metrics to include certain Bedrock Milestones that are designed to drive and support the
way the Company works by simplifying, standardizing, and automating critical processes to achieve the Elevate Summit Strategy.
As a result, in 2023, our performance metrics and weightings were as follows for our NEOs:

Metric and Weighting

Definition / Notes

Adjusted EBITDA (60%)

Net income (loss) before interest expense (income), income tax expense (benefit)
and depreciation, depletion and amortization, adjusted to exclude accretion, loss on
debt financings, transaction costs, non-cash compensation and certain other
non-cash and non-operating items.

EBITDA Margin (10%)

Adjusted EBITDA divided by net revenue.

Recordable Incident Rate (RIR) (10%)

Any employee work-related injury that requires medical treatment and results in a
positive diagnosis of an injury, a prescription or work restrictions (per OSHA), divided
by hours worked.

Safety Risk Assessments Reviewed
(SRAR) (10%)

Managers must review and give feedback on risk assessments developed by
employees to identify, analyze and suggest opportunities to reduce/eliminate the
hazards and/or risks associated with a specific task.

PERFORMANCE TARGETS AND PAYOUT RANGES

The achievement factor for each of the performance metrics was determined by multiplying the weight attributed to each
performance metric by the applicable payout percentage for each metric. For Adjusted EBITDA and EBITDA Margin payout
percentages were determined by calculating actual achievement against the target amount based on a pre-established scale.

Financial Performance

For Adjusted EBITDA and EBITDA Margin, payout percentages for actual performance between the specified threshold, target, and
maximum performance levels is interpolated on a straight-line basis. The following table shows the payout percentages associated
with various levels of achievement of Adjusted EBITDA and EBITDA Margin:

Safety Performance Targets

The overall safety metric achievement factor equals the sum of each metric’s payout percentage multiplied by its weighting. The
maximum payout opportunities for the safety metrics is 200% of target. For the safety metrics, payout percentages for actual
achievement between the specified threshold, target and maximum levels were adjusted on a linear basis. All safety targets
required year-over-year improvement in performance.

The targets for Adjusted EBITDA and EBITDA Margin were increased and decreased, respectively, to account for four acquisitions and one divestiture during the
year.

See ‘‘Reconciliation of Non-GAAP Measures to GAAP’’ on Annex A.

Bedrock Milestones had a target of meeting 3 of 4 strategic alternatives and maximum performance required meeting 4 of the 4 strategic alternatives.

PERSONAL PERFORMANCE MODIFIER

In 2023, each NEO had personal performance goals that were used to determine their 2023 personal performance modifier. The
personal performance modifier was applied to their annual cash incentive earned as disclosed above, subject to the individual
payout cap of 200% of target opportunity and the overall payout cap on the approved incentive pool funded by AEBITDA, EBITDA
Margin, Safety (RIR and SRAR), and Bedrock Milestones. The personal performance modifier was recommended by the CEO for
each NEO (other than the CEO) and approved by the Human Capital and Compensation Committee. For 2023, each NEO
received a personal modifier of 100%.

In determining the appropriate individual personal performance modifier for an NEO, the CEO and the Human Capital and
Compensation Committee, as applicable, reviewed the personal performance results made by each NEO for 2023. These personal
performance results related to, among other things, how the NEO could drive the execution of the Company’s Elevate Summit
vision and strategy, enhance organizational effectiveness, and enhance the effectiveness of their respective roles within the
Company.

Elements of Pay: Long-Term Equity Incentives

Our long-term equity incentives for NEOs in 2023 consisted of a balance of performance units (50%) and RSUs (50%). The Human
Capital and Compensation Committee uses competitive market data from our annual total compensation study to assist with
targeted long-term incentive value. In addition, the Human Capital and Compensation Committee considers individual
performance, potential future contributions to our business, internal equity and management’s recommendations except in the case
of the Chief Executive Officer.

Stock price performance

The 2023 performance units focus our executives on the long term performance of the Company relative to industry peers and
predetermined financial targets. The performance metrics are relative TSR and return on invested capital (‘‘ROIC’’).

The peer group for determining our relative TSR is separate and distinct from the peer group used to evaluate and set NEO
compensation levels discussed under ‘‘—Compensation Decision Process—Role of Peer Companies and Competitive Market
Data.’’ The Relative TSR peer group represents a broader array (typically near 65 to 70 companies) of industry peers competing for
stockholders and investors.

ROIC is determined for the performance period by dividing (i) the arithmetic mean of the following for each fiscal year during the
performance period: the Company’s Adjusted EBITDA (as reported on the Company’s audited financial statements) for each such fiscal
year, reduced by depreciation, depletion and amortization charges for such fiscal year by (ii) the arithmetic mean of the following for each
fiscal year during the performance period: the sum of the Company’s total outstanding long-term debt, stockholders’ equity, retained
earnings and accumulated other comprehensive income, in each case, as reported on the Company’s audited financial statements for
such fiscal year. The Compensation Committee believes that including ROIC as a performance metric incentivizes management to
maximize efficiency of capital deployed for the benefit of the Company’s stockholders.

The performance period for the performance units granted in February 2023 began on January 1, 2023 and ends on December 31,
2025 and are earned based on performance against the target below. Beginning in 2021, the performance units are measured
using the average three-year performance against one-year ROIC goals. The changes to the design of the performance units were
the result of the following:

•
•
•

The Company’s new leadership team embarking on a new strategy;
Allowed realistic performance targets to be set when management and the committee have the most current information; and
Allowed stronger shareholder alignment with the most realistic ROIC stretch targets.

32 | SUMMIT MATERIALS 2024 NOTICE OF ANNUAL MEETING AND PROXY STATEMENT

Earned amounts will be interpolated on a straight line basis for performance between threshold, target, and maximum performance
requirements. Financial goals are established based on a review of historical and strategic forward-looking performance criteria
and are established at reasonable but stretch performance requirements for threshold, target, and maximum payout opportunities.
We will proactively disclose the ROIC performance requirements and performance attainment at the completion of the three-year
performance period.

The target award values shown vary from the values listed in the 2023 Grants of Plan-Based Awards Table for two reasons. First, the 2023 Grants of Plan-Based
Awards Table uses the Monte Carlo valuation method, which determines the accounting expense for our performance units because 50% is based on Relative
TSR. This generated an expense value approximately 130% higher than the actual value on the grant date for the awards issued on February 22, 2023 to each of
our NEOs (other than Messrs. Anderson and Harris), and an expense value approximately 126% higher than the actual value on the grant date for the awards
issued on March 1, 2023 to Mr. Anderson. However, we do not believe the Monte Carlo accounting model is appropriate for purposes of setting total compensation
opportunity. Second, to mitigate the potential impact of short-term stock price swings on our equity grants, we use the 20-day average closing stock price
immediately preceding the grant date to determine the grant size, rather than the closing stock price on the actual grant date as shown in the 2023 Grants of
Plan-Based Awards Table.

(2)

The target award values for Mss. Noonan and Anderson and Messrs. Gaskill and Ghelani were based off of their base salaries as of February 1, 2023. The target
award value for Mr. Anderson was based off of his base salary as of March 1, 2023.

(3)

Pursuant to the Transition Agreement entered into between the Company and Mr. Harris, Mr. Harris did not receive any equity grants in 2023.

Performance Units Earned for the Performance Period 2021—2023

Performance units were granted to our NEOs then employed by the Company that were subject to 50% Relative TSR performance
and 50% ROIC performance for the three-year performance period beginning January 1, 2021 and ending December 31, 2023.
The Relative TSR peer group was companies in the Materials Sector and Capital Goods Sector in the S&P 400 Midcap Index.
Relative TSR performance was based on dividends plus beginning and ending stock prices based on the trailing 20-day average
closing price. During the performance period, our Relative TSR ranked at the 74th percentile resulting in a payout of 195.65% of
target. The ROIC performance goal achievement levels were as follows:

We have a tax-qualified contributory retirement plan established to qualify as a deferred salary arrangement under Section 401(k)
of the Internal Revenue Code of 1986, as amended (the ‘‘Code’’). The plan covers all U.S. employees, including our NEOs, who
are limited to their annual tax deferred contribution limit as allowed by the Internal Revenue Service (the ‘‘IRS’’). We provide for
matching contributions to the plan, including 100% of pre-tax employee contributions, up to 4% of eligible compensation. Employer
contributions vest immediately.

The Company also offers the members of a select group of management or highly compensated employees, including the NEOs,
the opportunity to supplement their retirement savings through the Summit Materials Deferred Compensation Plan (the ‘‘DCP’’). An
eligible participant in the DCP may elect to defer up to 50% of such participant’s base salary compensation and up to 100% of such
participant’s designated discretionary bonus award compensation and annual incentive award compensation. The DCP also
permits Company-provided credits to participants’ accounts, but no such credits are currently being made. Additional information
about the DCP is reflected in ‘‘—2023 Non-Qualified Deferred Compensation’’ below.

In alignment with a health and safety culture, the Company offers an Executive Health Program through the Mayo Clinic for the
CEO and the executive team, including all the NEOs. The Human Capital and Compensation Committee approved this program in
the Fall of 2021 and the use of this benefit is voluntary and not all executives will utilize it annually. The value of the program will
not exceed $10,000 annually for each eligible executive.

Compensation Discussion and Analysis—How We
Paid

Our Compensation Philosophy

Our executive compensation program is intended to attract, motivate and retain executive officers and to align the interests of our
executive officers with stockholders’ interests.

The Board’s objectives for our program include, but are not limited to, the following:

To offer competitive 
total compensation 
opportunities 
compared to our 
peers and to 
balance the need 
for talent with 
reasonable 
compensation 
expense

Say-on-Pay Votes

To enhance 
stockholder value 
by focusing 
management on 
financial metrics 
that drive value

To recognize and 
reward executives 
whose knowledge, 
skills and 
performance are 
critical to our 
success

To attract, motivate 
and retain executive 
talent willing to 
commit to long-term 
stockholder value 
creation

To align executive 
decision making 
with business 
strategy and 
discourage 
excessive risk 
taking

In 2023, the Human Capital and Compensation Committee considered the outcome of the stockholder advisory vote on 2022
executive compensation when making decisions relating to the compensation of our NEOs and our executive compensation
program and policies. Our stockholders voted at our 2023 annual meeting, in a nonbinding advisory vote, on the 2021
compensation paid to our NEOs. Our stockholders overwhelmingly (99%) approved the compensation of our NEOs. Based on
the level of support, the Human Capital and Compensation Committee determined that stockholders generally support our
compensation practices. The Company has determined to hold this advisory, say-on-pay vote annually, consistent with the stated
preferences of our stockholders and with the results of our 2023 Annual Meeting of Stockholders where the majority of the votes
cast were in favor of an annual advisory vote.

In addition, the Company continued its efforts to reach out to investors for feedback in 2023. During the year, the Company’s
investor relations department contacted many of the Company’s largest investors and engaged in conversations with a significant
portion of the investor base. The feedback received in these conversations was generally positive in regard to the Company’s
compensation programs. The Human Capital and Compensation Committee intends to continue to consider the views of our
stockholders when designing, reviewing and administering the Company’s compensation programs and policies.

Compensation Decision Process

Role of the
Human Capital
and
Compensation
Committee

The Human Capital and Compensation Committee is responsible to our Board for oversight of our executive
compensation program. The Human Capital and Compensation Committee is responsible for the review and
approval of all aspects of our program.

Among its duties, the Human Capital and Compensation Committee is responsible for:

•

•

•

•

Assessing competitive market data from the Independent Compensation Consultant

Reviewing each NEO’s performance in conjunction with competitive market data and, accordingly,
approving compensation recommendations including, but not limited to, base salary, annual bonus,
long-term incentives, and benefits/perquisites

Considering, recommending and approving incentive plan goals, achievement levels, and program
structure

Incorporating meaningful input from our stockholders, if applicable

2024 NOTICE OF ANNUAL MEETING AND PROXY STATEMENT SUMMIT MATERIALS | 35

Role of
Management

For each NEO excluding herself, our Chief Executive Officer recommends to the Human Capital and
Compensation Committee compensation levels for NEOs based on a review of market data and individual
performance. The Human Capital and Compensation Committee reviews and discusses all recommendations
prior to issuing its approval.

For the Chief Executive Officer, during executive session without the Chief Executive Officer present, the
Human Capital and Compensation Committee is solely responsible for assessing performance and making
compensation recommendations to the Board for approval. Management does not make
compensation-related recommendations for the Chief Executive Officer.

Role of the
Independent
Compensation
Consultant

In 2023 the Human Capital and Compensation Committee retained the Independent Compensation
Consultant in accordance with the Human Capital and Compensation Committee’s charter. The Independent
Compensation Consultant reports directly to the Human Capital and Compensation Committee. The Human
Capital and Compensation Committee retains sole authority to hire or terminate the Independent
Compensation Consultant, approve its fees, determine the nature and scope of services and evaluate the
Independent Compensation Consultant’s performance.

A representative of the Independent Compensation Consultant attends Human Capital and Compensation
Committee meetings, as requested, and communicates with the Human Capital and Compensation
Committee chair between meetings. The Human Capital and Compensation Committee makes all final
decisions and recommendations.

The Independent Compensation Consultant’s roles include, but are not limited to, the following:

•

•

•

•

•

Advising the Human Capital and Compensation Committee on executive compensation trends and
regulatory developments;

Developing a peer group of companies for determining competitive compensation amounts and
practices;

Providing a total compensation study for executives against peer companies;

Providing advice to the Human Capital and Compensation Committee on governance best practices,
as well as any other areas of concern or risk; and

Reviewing and commenting on proxy disclosure items, including the CD&A.

The Human Capital and Compensation Committee has assessed the independence of the Independent
Compensation Consultant, considering all relevant factors, including those set forth in Rule 10C-1(b)(4)(i) through
(vi) under the Exchange Act. Based on this review, the Human Capital and Compensation Committee concluded
that there are no conflicts of interest raised by the work performed by the Independent Compensation Consultant
and that the Independent Compensation Consultant is independent.

Role of Peer
Companies and
Competitive
Market Data

In the Fall of 2022, to assist with 2023 compensation decisions, the Independent Compensation Consultant
performed a competitive pay study. To develop competitive market values for the NEOs, the Independent
Compensation Consultant developed, and the Human Capital and Compensation Committee approved, a peer
group of 16 companies.

The peer group development criteria used in the 2022 included:

•

•

•

•

•

•

Industry: Companies in the building products, construction materials, forest products, and mining industries

Company size: Approximately 0.4x to 3x times our annual revenues (primary factor), with market
capitalization reviewed as a secondary factor

ISS: Companies considered by Institutional Shareholder Services (‘‘ISS’’) to be the Company’s
compensation peers and used in ISS’ annual report regarding the Company

Peers of Peers: Companies used in the peer groups of potential peer companies

Consistency: Companies contained in the peer group in the prior year

Peers: Companies using Summit in their peer group

36 | SUMMIT MATERIALS 2024 NOTICE OF ANNUAL MEETING AND PROXY STATEMENT

The approved peer group had annual revenues which ranged from approximately $1.2 billion to $6.6 billion, with
average / median annual revenue of approximately $3.2 billion and $2.8 billion, respectively. For our Fall 2022 total
compensation study, our annual revenues were estimated at approximately $2.4 billion. The Independent
Compensation Consultant developed size adjusted market values (regression analysis) for each position using our
annual revenue.

The 50th percentile for total compensation is a key reference point for the Human Capital and Compensation
Committee; however, the Human Capital and Compensation Committee also considers other factors, including,
experience, performance and expected future contributions. For positions where peer company proxy data was not
available, the Independent Compensation Consultant utilized published and private compensation survey sources.

TIMING OF COMPENSATION DECISIONS

Pay recommendations for our executives, including the NEOs, are made by the Human Capital and Compensation Committee,
typically, at its first scheduled meeting of the fiscal year, which normally occurs in February around the same time we report our
fourth quarter and year-end financial results for the preceding fiscal year and provide our financial guidance for the upcoming year
(the ‘‘first meeting’’). This timing allows the Human Capital and Compensation Committee to have a complete financial performance
picture prior to making compensation decisions.

Decisions with respect to prior year performance, as well as annual equity awards, base salary increases and target performance
levels for the current year are typically made at the first meeting. Any equity awards recommended by the Human Capital and
Compensation Committee at this meeting are reviewed by the Board and, if approved, are dated on the date approved by the
Board either at a subsequent board meeting or via written consent. As such, the Human Capital and Compensation Committee
does not time the grants of equity incentives to the release of material non-public information.

The exceptions are grants to executives who are promoted or hired from outside the Company during the year, and discretionary
grants made throughout the year for retention and extraordinary purposes. These executives may receive compensation changes
or equity grants effective or dated, as applicable, as of the date of their promotion, hiring date, or other Board approval date.

DETERMINATION OF CHIEF EXECUTIVE OFFICER COMPENSATION

Pay recommendations for our Chief Executive Officer are made by the Human Capital and Compensation Committee, in an
executive session without the Chief Executive Officer present, typically, at its first scheduled meeting of the fiscal year. The Human
Capital and Compensation Committee also reviews and evaluates Chief Executive Officer performance, and determines
performance achievement levels, for the prior fiscal year. The Human Capital and Compensation Committee also reviews
competitive compensation data from the peer group companies. The Human Capital and Compensation Committee typically
approves, or presents, pay recommendations for the Chief Executive Officer to the Board, excluding the Chief Executive Officer, for
approval. If applicable, during executive session, the Board conducts its own review and evaluation of the Chief Executive Officer’s
performance taking into consideration the recommendations of the Human Capital and Compensation Committee.

EQUITY PLAN

The Company maintains the Omnibus Incentive Plan which allows for grants of equity-based awards in the form of stock options,
stock appreciation rights, restricted stock and RSUs, performance units, undivided fractional limited partnership interests in Summit
Holdings and other stock-based awards.

Governance of Executive Compensation

STOCK OWNERSHIP GUIDELINES

We have established stock ownership guidelines for our Chief Executive Officer, officers reporting to the Chief Executive Officer,
and directors. The approved guidelines are as follows:

•

•

•

Chief Executive Officer: 6x base salary

Section 16 Officers reporting to the Chief Executive Officer: 2.5x base salary

Directors: 5x annual cash retainer

Participants are expected to comply with the ownership requirements within five years of an appointment to a qualified position.
Once the ownership requirements have been satisfied, future declines in share price will not affect compliance so long as the
participant holds the number of equity interests he or she had at the time he or she achieved the expected ownership level. The
Company monitors each participant’s compliance with the guidelines on a quarterly basis, and as of February 16, 2024, the most
recent date on which compliance was monitored, all of our executive officers were in compliance with the guidelines.

The following components satisfy the ownership guidelines: Equity interests owned directly or indirectly (e.g., by or with a spouse
or held in trust for the individual or one or more family members of the individual), and equity interests, including unvested RSUs,
held in qualified or nonqualified savings, profit sharing, or deferred compensation accounts. In 2023, the Company amended its
stock ownership guidelines so that the value of in-the-money spread of shares underlying vested but unexercised stock options
and value of in-the-money spread of shares underlying vested but unexercised warrants are no longer attributed towards satisfying
compliance with the guidelines. At least quarterly, the Human Capital and Compensation Committee monitors participants’
compliance with these guidelines.

INCENTIVE COMPENSATION RECOUPMENT (‘‘INCENTIVE CLAWBACK’’) POLICIES

Our Board adopted the Summit Materials, Inc. Incentive Compensation Clawback Policy (the ‘‘Policy’’) pursuant to NYSE rules and
because it believes that it is in the best interests of the Company and its stockholders to create and maintain a culture that
emphasizes integrity and accountability and that reinforces the Company’s pay-for-performance compensation philosophy. This
policy applies to any current and former ‘‘Executive Officer’’ of the Company, as such term is defined under the Policy. The Policy
applies to certain incentive-based compensation (‘‘Incentive Compensation’’). Under the Policy, the Company is required to recover
any ‘‘Erroneously Awarded Compensation’’ that is ‘‘Received’’ by a ‘‘Covered Executive’’ as such terms are defined in the Policy.

In addition, each of the RSU, stock option and performance unit award agreements under the Omnibus Incentive Plan generally
provides that if a restrictive covenant violation occurs or the Company discovers after a termination of employment or services that
grounds existed for ‘‘cause’’ (as defined in the Omnibus Incentive Plan) at the time thereof, then the participant shall be required, in
addition to any other remedy available (on a non-exclusive basis), to pay to the Company, within ten business days of the
Company’s request to the participant therefor, an amount equal to the aggregate after-tax proceeds (taking into account all
amounts of tax that would be recoverable upon a claim of loss for payment of such proceeds in the year of repayment) the
participant received upon the sale or other disposition of, or distributions in respect of, the equity award thereunder and any shares
issued in respect thereof (minus, in the case of options, the aggregate cost (if any) of the shares). Without limiting the foregoing, all
awards are subject to reduction, cancellation, forfeiture or recoupment to the extent necessary to comply with applicable law.

Compensation Risk Assessment

Our governance policies and compensation structure are not reasonably likely to have a material adverse effect on the Company.
The Independent Compensation Consultant and management delivered a compensation risk assessment report to the Human
Capital and Compensation Committee in 2023. The following features of our program mitigate risk:

The Human Capital and Compensation Committee consults with the Independent Compensation Consultant to assist
with annual compensation decisions

The Human Capital and Compensation Committee approves the annual incentive plan’s financial goals at the start of
the fiscal year, and approves the performance achievement level and final payments earned at the end of the fiscal
year

The Human Capital and Compensation Committee benchmarks total compensation opportunity for executive positions
using multiple survey sources and has discretion over payout calculations and oversight of compensation plans for our
executives

38 | SUMMIT MATERIALS 2024 NOTICE OF ANNUAL MEETING AND PROXY STATEMENT

We utilize a mix of cash and equity variable incentive programs, with a balanced mix of RSUs and performance units,
which are subject to multi-year vesting

Our performance units payout opportunities are capped at 200% of the target total opportunity

We utilize competitive change-in-control severance programs to help ensure executives continue to work towards our
stockholders’ best interests in light of potential employment uncertainty

Executive officers are subject to minimum stock ownership guidelines

Incentive Compensation Clawback Policy that is compliance with the rules of the NYSE and permits the Company to
recoup certain incentive-based compensation

The amount reported in the Bonus column for 2022 reflects the one-time cash sign-on bonus of $50,000 paid to Mr. Ghelani pursuant to his offer letter.

The amounts reported in the Stock Awards column for 2023 reflect the aggregate grant date fair value of stock awards granted in fiscal 2023, calculated in
accordance with ASC 718, utilizing the assumptions discussed in Note 13, Stock-Based Compensation, to our audited consolidated financial statements included
in the 2023 Annual Report. The fiscal 2023 awards consist of time-vesting RSUs and performance units. As the performance units vest according to Relative TSR,
they are subject to market conditions, and not performance conditions, as defined under ASC 718, and therefore have no maximum grant date fair values that
differ from the grant date fair values presented in the table.

Reflects non-equity incentive plan compensation awards for services rendered during the fiscal year presented. For more information, see ‘‘Compensation
Discussion and Analysis—Compensation Elements—Annual Cash Incentives.’’

All Other Compensation for 2023 includes (a) amounts contributed by Summit LLC under the Summit Materials, LLC Retirement Plan in an amount equal to
$13,200 for each NEO and (b) severance payments of $121,346 to Mr. Harris. For Ms. Noonan, All Other Compensation for 2023 also includes (a) payments for
life insurance ($21,680), (b) amounts paid by the Company for the Executive Health Program ($6,454), (c) amounts contributed by the Company to her Health
Savings Account (‘‘HSA’’), (d) nominal amounts related to parking, and (e) entertainment expenses for Ms. Noonan and her spouse related to business events at
which spouses were expected to attend. For Mr. Anderson, All Other Compensation for 2023 also includes (a) amounts paid by the Company for certain relocation
costs for Mr. Anderson in connection with his promotion ($86,141), (b) amounts paid by the Company for the Executive Health Program, (c) amounts contributed
by the Company to his HSA, and (d) entertainment expenses for Mr. Anderson and his spouse related to business events at which spouses were expected to
attend. The aggregate value of perquisites received by each of Ms. Anderson and Messrs. Gaskill, Ghelani, and Harris did not exceed $10,000.

Reflects the possible payouts of cash incentive compensation under the Non-Equity Incentive Plan. Amounts reported in the ‘‘Threshold’’ column assume that
each NEO only earns the minimum payout for either RIR or SRAR and there is no payout for any other component of the annual cash incentive program. The
actual amounts paid are described in the ‘‘Non-Equity Incentive Plan Compensation’’ column of the ‘‘Summary Compensation Table.’’

Reflects the performance units granted in 2023, which have a three-year performance period ending December 31, 2025, and vest based on Relative TSR and
ROIC performance. Threshold assumes that 50% of the total performance units awarded vest and maximum assumes that 200% of the total performance units
awarded vest.

Reflects the RSUs granted in 2023.

Represents the grant date fair value of the performance units and RSUs granted in 2023 with respect to the NEOs. The assumptions applied in determining the
fair value of the awards are discussed in Note 13, Stock-Based Compensation, to our audited consolidated financial statements included in the 2023 Annual
Report.

For 2023, Mr. Harris’ annual cash incentive was prorated based on the number of days he was employed by the Company in 2023. Pursuant to the Transition
Agreement entered into between the Company and Mr. Harris, Mr. Harris did not receive any new equity awards in 2023.

Offers of Employment and Employment Arrangements

Mss. Anderson and Noonan and Messrs. Gaskill, Ghelani, and Anderson each has a signed offer of employment. The offers of
employment and employment agreement provide for base salary subject to annual adjustment by the Board, an annual incentive
award, participation in Company-sponsored broad-based and executive benefit plans and such other compensation as may be
approved by the Board.

Pursuant to Mr. Anderson’s offer letter dated February 23, 2023, his annual base salary would be $566,800, and he would be
eligible to participate in the Company’s Annual Cash Bonus with a target of 75% of his annual base salary and the Company’s
Long-Term Equity Incentive with a grant date fair value of 125% of his annual base salary. The offer letter also entitled
Mr. Anderson to receive assistance with certain relocation expenses.

Mr. Harris’ Transition and Consulting Agreement

On September 8, 2022, Mr. Harris informed the Company of his intention to retire from the Company. In order to provide for an orderly
transition of Mr. Harris’ responsibilities and duties, the Company and Mr. Harris entered into a Transition and Consulting Agreement,
dated as of September 8, 2022 (the ‘‘Transition Agreement’’), which was approved by the Human Capital and Compensation
Committee of the Board and superseded Mr. Harris’ existing employment agreement and participation notice and agreement under
the Company’s Senior Personnel Severance Plan (the ‘‘Severance Plan’’) (other than as described in the Transition Agreement).

The Transition Agreement provided that Mr. Harris would transition from the role of Executive Vice President and Chief Financial Officer
on the date immediately prior to the date on which Mr. Harris’ successor as Chief Financial Officer is appointed and commences services
(such date, the ‘‘Transition Date’’). On the Transition Date, Mr. Harris became a Senior Advisor and served in such non-executive officer
position until his employment ended on the later of (x) 30 days following the Transition Date and (y) October 16, 2023 (as applicable, the
‘‘Employment Termination Date’’). During the period from the Transition Date through the Employment Termination Date, Mr. Harris
assisted with the transition of his finance duties, continued performing his other operational responsibilities, assisted with specified
strategic goals as the Company continued to execute its Elevate Summit Strategy, and performed such other duties and rendered such
other services as were reasonably requested from time to time by his successor or the Company’s Chief Executive Officer (the ‘‘CEO’’).
In return for Mr. Harris’ services from September 8, 2022 through the Employment Termination Date, he (i) continued to receive his
current base salary of $631,000 per year through the Employment Termination Date; (ii) was eligible to earn an annual cash performance
bonus with a target of 75% of base salary, subject to applicable performance metrics, for fiscal year 2022 and/or 2023 (or the applicable
portion thereof, subject to the ‘‘Bonus Condition’’ described below); (iii) was not be eligible to receive new equity awards; (iv) was entitled
to participate in Company employee benefit plans; and (v) had his equity awards continue to vest pursuant to their terms. Additionally,
Mr. Harris remained eligible to participate in the Executive Severance Plan (the ‘‘Severance Plan’’) through the Employment Termination
Date, after which his participation ended. If Mr. Harris’ employment was terminated prior to the Employment Termination Date, (i) he
would only be entitled to payments pursuant to the Severance Plan upon a ‘‘Qualifying Change in Control Termination’’ or ‘‘Qualifying
Termination’’ per the terms of the Severance Plan and (ii) his existing equity awards would be treated in accordance with the retirement or
forfeiture provisions of the applicable award agreements.

Further, Mr. Harris agreed that he would remain available for consultation from the Employment Termination Date through
December 31, 2024 (the ‘‘Consulting Period’’). During the Consulting Period, Mr. Harris will provide such consulting services as
may be reasonably requested from time to time by his successor or the CEO, which services are expected to include (a) advising
on and assisting with quarterly, annual close and reporting, (b) assisting with annual budgeting and forecasting, (c) assisting with
transitioning his operational responsibilities, (d) advising on the Company’s capital structure and financings, (e) advising on matters
related to the Company’s ‘‘up-C’’ structure, including its Tax Receivable Agreement, and (f) performing such other duties and
rendering such other services as are reasonably requested from time to time by his successor or the CEO. During the Consulting
Period, and provided he signs and does not revoke a release (as described below), Mr. Harris will (i) continue to be paid by the
Company at the monthly equivalent of his annual base salary; (ii) receive the fiscal 2023 annual bonus (pro-rated for the portion of
such year prior to the Transition Date) based on actual performance (the ‘‘Bonus Condition’’); (iii) receive cash payments equal to
the amount of his monthly COBRA insurance premiums through the earlier of the end of the Consulting Period or when he obtains
coverage through a third-party employer; and (iv) be eligible for an annual executive physical exam under the Company’s executive
health program. In the event that the consulting services are terminated (A) due to Mr. Harris’ death or disability, (B) by the
Company without cause prior to a change in control, or (C) by the Company following a change in control, Mr. Harris (or his
beneficiary or estate, as applicable) will receive any remaining payments and benefits as if such termination had not occurred. In
the event that the consulting services are terminated by the Company for cause or by Mr. Harris, Mr. Harris will not receive the
remaining payments and benefits (other than accrued and unpaid consulting fees).

Amounts in this column are not reported as compensation for fiscal 2023 in the ‘‘Summary Compensation Table’’ since they do not reflect above-market or
preferential earnings.

(2) Mr. Harris commenced participation in the DCP in fiscal 2016 and $305,388 was previously reported in the ‘‘Salary’’ column for 2022, $309,515 was previously
reported in the ‘‘Salary’’ column for 2021, and $468,501 was previously reported in the ‘‘Non-Equity Incentive Plan Compensation’’ column for 2022 in the
‘‘Summary Compensation Table.’’

Pursuant to the DCP, an eligible participant may elect to defer up to 50% of such participant’s base salary compensation (in 5%
increments) and up to 100% of such participant’s designated discretionary bonus award compensation and annual incentive award
compensation (in 5% increments). Deferral elections are generally made by participants prior to the close of the taxable year
preceding the taxable year for which the applicable compensation is earned. The DCP also permits Company-provided credits to
participants’ accounts, but no such credits are currently being made. Participants are permitted to make individual investment
elections that will determine the rate of return on their deferral amounts under the DCP and may change their investment elections
at any time. Deferrals are only deemed to be invested in the investment options selected. Participants have no ownership interest
in any of the funds as investment elections are used solely to measure the amounts of investment earnings or losses that will be
credited or debited to the participants’ accounts on the Company’s books and records. Investment funds are valued each day that
the NYSE is open for trading. Participant deferrals under the DCP and the earnings thereon are always 100% vested.

The table below shows the funds in which our NEOs invested during 2023, and their rate of return from January 1, 2023 through
December 31, 2023.

A DCP participant may elect, at the time of such participant’s deferral elections, to receive benefit distributions upon (i) separation
from service with the Company or (ii) following the earlier of (a) a specified date that occurs no earlier than at least three years from
the end of the calendar year in which the deferred compensation is credited or (b) separation from service with the Company.
Additionally, a DCP participant may elect, at the time of such participant’s deferral elections, to receive benefit distributions in the
form of (i) a single lump sum payment or (ii) for distributions following retirement, annual installments with an installment term of
between two and 15 years. A participant may elect to change the benefit distribution date and/or form under certain circumstances
specified in the DCP. In addition, in the event of certain unforeseeable emergencies, a participant may apply for immediate
distribution in an amount necessary to satisfy such financial hardship and the tax liability attributable to such distribution. In the
event of a participant’s death or disability, the entire value of such participant’s account will be distributed in a single lump sum.

Potential Payments Upon Termination or Change in Control

EXECUTIVE SEVERANCE PLAN

The Board, upon the recommendation of the Human Capital and Compensation Committee, adopted the Severance Plan in
December 2017, which provides severance benefits to certain executive officers of the Company and its affiliates in the event that
an eligible employee experiences a termination of employment by the Company without ‘‘cause’’ (and other than due to death or
disability) or by the employee as a result of a ‘‘constructive termination’’ (as such terms are defined in the Severance Plan) (each, a
‘‘Qualifying Termination’’). In the event that a Qualifying Termination occurs during the two-year period beginning on the date of a
change in control (each such termination, a ‘‘Qualifying Change in Control Termination’’), the Severance Plan provides enhanced
severance benefits. In connection with implementing the Severance Plan, all participants in the Severance Plan waived the
provisions of any applicable employment agreement that would have applied under the conditions set forth under the Severance
Plan, other than any provisions in such employment agreements which were intended to survive the termination of such
employment agreement.

Each participant in the Severance Plan (a ‘‘Participant’’) is designated as a Tier 1 Participant or Tier 2 Participant. Tier 1
Participants are limited to the Chief Executive Officer. Tier 2 Participants are limited to Executive Vice Presidents. Accordingly,
Ms. Noonan is a Tier 1 Participant and Messrs. Anderson, Gaskill and Ghelani and Ms. Anderson are each Tier 2 Participants.
Messr. Harris was a Tier 2 Participant.

In the event of a Qualifying Termination, Participants are provided with the following payments and benefits:

•

•

a pro-rata payment representing the amount otherwise payable under the annual bonus program for the fiscal year in
which termination of the Participant’s employment occurs, based on actual performance and payable concurrently with
cash bonus payments to other employees (but in all events on or about March 15 of the immediately following fiscal year)
(a ‘‘Pro-Rata Bonus’’), and to the extent not previously paid, the amount otherwise payable under the annual bonus
program for the immediately preceding fiscal year, payable concurrently with cash bonus payments to other employees
(a ‘‘Prior Year Bonus’’);

a cash payment (i) for a Tier 1 Participant, of 2.5 times the Participant’s annual base salary, payable over a period of
36 months, and (ii) for a Tier 2 Participant, of 2 times the Participant’s annual base salary, payable over a period of
24 months; and

2024 NOTICE OF ANNUAL MEETING AND PROXY STATEMENT SUMMIT MATERIALS | 45

•

a cash payment, payable monthly in accordance with the Company’s payroll practices, (i) for a Tier 1 Participant, for up
to 36 months, and (ii) for a Tier 2 Participant, for up to 24 months, in each case in an amount equal to the total amount of
the monthly COBRA insurance premiums for participation in the health, dental, and vision benefit programs of the
Company in which the Participant participated as of the date of termination (the ‘‘COBRA Benefits’’).

In the event of a Qualifying Change in Control Termination, Participants are provided with the following payments and benefits:

•

•

•

a Pro-Rata Bonus, and, if applicable, a Prior Year Bonus;

a cash payment of (i) for a Tier 1 Participant, 3 times the sum of the Participant’s annual base salary and target annual
bonus, and (ii) for a Tier 2 Participant, 2 times the sum of the Participant’s annual base salary and target annual bonus, in
each case of (i) and (ii), payable in a lump sum no later than the 60th day following the date of termination; and

the COBRA Benefits.

The payments and benefits provided under the Severance Plan are subject to each Participant’s execution and delivery of a
release of claims and each Participant’s compliance with non-competition, non-disparagement, non-solicitation and confidentiality
covenants applicable pursuant to each Participant’s Participation Notice and Agreement under the Severance Plan. The
non-disparagement and confidentiality covenants each have an indefinite term and the non-competition and non-solicitation
covenants each have a term of 24 months following the Participant’s date of termination. Additionally, the Severance Plan provides
that if a Participant is subject to an excise tax under Section 4999 of the Code, then the payments and benefits the Participant
receives may be reduced so that the excise tax does not apply; however, such reduction will only occur if it results in the receipt of
a greater after-tax severance than would otherwise be provided.

Treatment of Long-Term Incentive Awards Upon Termination or Change in Control

Each of the RSUs and performance units granted in 2023 is subject to restrictive covenants related to post-employment
(i) employee, client and consultant non-solicitation and (ii) non-competition, in each case for 12 months following any termination of
employment and indefinite covenants covering confidentiality and non-disparagement (participant only). Further, the equity awards
and all proceeds therefrom are generally subject to the Company’s Incentive Compensation Clawback Policy and any other
incentive clawback policies, as in effect from time to time, to the extent the participant is a director or ‘‘officer’’ as defined under
Rule 16a-1(f) of the Exchange Act. Additional provisions regarding the treatment of the equity awards upon a termination of
employment are outlined in the table below.

All outstanding stock options are fully vested.

Stock options do not remain exercisable past the original expiration date. In addition, the exercisability period expires immediately upon the occurrence of a
‘‘restrictive covenant violation’’ (as defined in the award agreement).

‘‘Retirement’’ is generally defined in the equity awards as termination of employment, other than for cause or while grounds for cause exist, and other than due to
the participant’s death or disability, following the date on which (i) the participant attains age 62 and (ii) the number of completed years of employment with the
Company and its affiliates is at least five. For stock options and RSUs, continuation of vesting after termination of employment is subject to the non-occurrence of
a ‘‘restrictive covenant violation.’’

‘‘Constructive termination’’ is generally defined in the equity awards as (i) having the meaning set forth in any employment agreement entered into by and between
the participant and the Company or an affiliate, or (ii) if no such agreement exists, any of the following, without the participant’s prior written consent: (a) a material
reduction in base salary or, to the extent applicable, target bonus opportunity (other than in connection with an across-the-board reduction in compensation of
similarly-situated employees of, on an individual-by-individual basis, less than 10%), (b) a material diminution of authority, duties, or responsibilities, (c) a
relocation of the participant’s primary place of business by more than 50 miles from its then-current location, or (d) any material breach by the Company of any
written agreement relating to the participant’s compensation (including any equity awards). ‘‘Constructive termination’’ provisions are limited to the Chief Executive
Officer and his direct reports and other Section 16 officers.

Prorated based on the number of days in the applicable year or in the performance period, as applicable, that have elapsed prior to termination of employment.

Vesting of the prorated portion at the end of the performance period is subject to the non-occurrence of a ‘‘restrictive covenant violation,’’ in the case of each
applicable termination scenario.

TERMINATION BENEFITS TABLE

The following table describes the potential payments and benefits under the Company’s Severance Plan and equity award agreements
to which the NEOs (other than Mr. Harris, see ‘‘Narrative Disclosure to Summary Compensation Table and Grants of Plan Based Awards
Table—Mr. Harris’ Transition and Consulting Agreement’’) would have been entitled assuming an eligible termination of employment or
change in control occurred on December 29, 2023, the last business day of fiscal 2023. A description of the provisions governing such
payments under our agreements and any material conditions or obligations applicable to the receipt of payments are described above
under ‘‘Executive Severance Plan’’ and ‘‘Treatment of Long-Term Incentive Awards Upon Termination or Change in Control.’’

The amounts shown in the table do not include payments and benefits to the extent they are provided generally to all salaried
employees upon termination of employment and do not discriminate in scope, terms or operation in favor of the NEOs. These
include accrued but unpaid salary and distributions of vested plan balances under our 401(k) savings plans.

In the event of a ‘‘constructive termination’’ or termination by the Company without ‘‘cause’’ (each term as defined in the Severance Plan), the cash severance
payment includes the following:

•

•

Ms. Noonan – a cash payment of 3 times her annual base salary, payable over a period of 36 months.

Messrs. Gaskill, Ghelani, and Anderson and Ms. Anderson – a cash payment of 2 times each NEO’s annual base salary, payable over a period of 24 months.

In the event of a constructive termination or termination by the Company without cause during the two-year period beginning on the date of a change in control of
the Company, the cash severance payment includes the following:

•

•

Ms. Noonan – a cash payment payable in a lump sum no later than the 60th day following the date of termination equal to 3 times the sum of her annual
base salary and target annual bonus for 2023.

Messrs. Gaskill, Ghelani, and Anderson and Ms. Anderson – a cash payment payable in a lump sum no later than the 60th day following the date of
termination equal to 2 times the sum of each NEOs annual base salary and target annual bonus for 2023.

Pro-rata bonus represents the amount otherwise payable under the annual bonus program for the fiscal year in which termination of the Participant’s employment
occurs, based on actual performance and payable concurrently with cash bonus payments to other employees (but in all events prior to March 15 of the
immediately following fiscal year).

COBRA benefit represents a cash payment in an amount equal to the total amount of the monthly COBRA insurance premiums for participation in the health,
dental, and vision benefit programs of the Company in which the NEO participated as of the date of termination, payable monthly in accordance with the
Company’s payroll practices. The terms of these payments are the following:

•

•

Ms. Noonan – for up to 36 months.

Messrs. Gaskill, Ghelani, and Anderson and Ms. Anderson – for up to 24 months.

In the event of a Qualifying Change in Control Termination or a Change in Control, the amount reported assumes performance units are not continued, converted,
assumed, or replaced by the Company or successor entity and therefore reflects full vesting at target. In addition, the amount reported assumes that the
Compensation Committee had not yet certified the performance of the performance units with a performance period of 2021—2023, which subsequently resulted
in a payout equal to 160.7% of target.

The Peer Group TSR set forth in this table utilizes the S&P 500 Construction Materials Industry Index, which we also utilize in the stock performance graph
required by Item 201(e) of Regulation S-K included in our Annual Report for the year ended December 30, 2023. The comparison assumes $100 was invested for
the period starting December 28, 2019, through the end of the listed year in the Company and in the S&P 500 Construction Materials Industry Index, respectively.
Historical stock performance is not necessarily indicative of future stock performance.

(5) We determined Adjusted EBITDA to be the most important financial performance measure used to link Company performance to Compensation Actually Paid to
our PEO and Non-PEO NEOs in 2023. Adjusted EBITDA is a non-GAAP measure. For more information on Adjusted EBITDA, please see the ‘‘Elements of Pay:
Annual Cash Incentives’’ section of the Compensation Discussion & Analysis in this proxy statement. This performance measure may not have been the most
important financial performance measure in prior years and we may determine a different financial performance measure to be the most important financial
performance measure in future years.

Recordable Incident Rate

Chief Executive Officer Pay Ratio

To determine our median employee pay in 2023, we chose taxable wages as our consistently applied compensation measure in
order to identify our median employee as of December 31, 2023. We calculated the median employee's annual total compensation
for 2023 in accordance with the requirements of the Summary Compensation Table. For 2023, the median employee’s annual total
compensation was $58,555 and the annual total compensation of our CEO was $6,993,815. Accordingly, for 2023, the ratio of CEO
pay to median employee pay was 119:1.

This pay ratio is a reasonable estimate calculated in a manner consistent with SEC rules and the methodology described above.
The SEC rules for identifying the median compensated employee and calculating the pay ratio based on such employee’s annual
total compensation allow companies to adopt a variety of methodologies, to apply certain exclusions, and to make reasonable
estimates and assumptions that reflect their compensation practices. As such, the pay ratio reported by other companies may not
be comparable to the pay ratio reported above, as other companies may have different employment and compensation practices
and may utilize different methodologies, exclusions, estimates and assumptions in calculating their own pay ratios.

OUR AUDITORS

ITEM 3
RATIFICATION OF APPOINTMENT OF
KPMG LLP

Under the rules and regulations of the SEC, the NYSE and the Public Company Accounting Oversight Board (the ‘‘PCAOB’’), the
Audit Committee is directly responsible for the appointment, compensation, retention and oversight of our independent registered
public accounting firm. In addition, the Audit Committee considers the independence of our independent registered public
accounting firm and participates in the selection of the independent registered public accounting firm’s lead engagement partner.
The Audit Committee has appointed, and, as a matter of good corporate governance, is requesting ratification by our stockholders
of the appointment of, the registered public accounting firm of KPMG to serve as independent registered public accounting firm for
the fiscal year ending December 28, 2024. KPMG has served as our independent registered public accounting firm since 2012.

The Board and the Audit Committee believe that the continued retention of KPMG as the Company’s independent registered public
accounting firm is in the best interests of the Company and its stockholders. If stockholders do not ratify the selection of KPMG, the
Audit Committee will evaluate the stockholder vote when considering the selection of a registered public accounting firm for the
audit engagement for the 2024 fiscal year. In addition, even if stockholders ratify the selection of KPMG as independent registered
public accounting firm, the Audit Committee may nevertheless periodically request proposals from the major registered public
accounting firms and as a result of such process may select KPMG or another registered public accounting firm as our independent
registered public accounting firm.

THE BOARD RECOMMENDS A VOTE ‘‘FOR’’ RATIFICATION
OF THE APPOINTMENT OF KPMG AS OUR INDEPENDENT
REGISTERED PUBLIC ACCOUNTING FIRM FOR THE FISCAL
YEAR ENDING DECEMBER 28, 2024.

INDEPENDENT REGISTERED PUBLIC ACCOUNTING
FIRM

Representatives of KPMG are expected to attend the Annual Meeting and will have an opportunity to make a statement and to
respond to appropriate questions from stockholders.

Consistent with SEC and PCAOB requirements regarding auditor independence, the Audit Committee has responsibility for
appointing, setting compensation for and overseeing the work of the independent registered public accounting firm. In recognition
of this responsibility, the Audit Committee has established a policy to pre-approve all audit and permissible non-audit services
provided by the independent registered public accounting firm.

Prior to engagement of the independent registered public accounting firm for the next year’s audit, management will submit to the
Audit Committee for approval a list of services and related fees expected to be rendered during that year within each of the
following four categories of services:

•

•

•

•

Audit services include audit work performed on the financial statements and internal control over financial reporting, as
well as work that generally only the independent registered public accounting firm can reasonably be expected to
provide, including comfort letters, statutory audits and discussions surrounding the proper application of financial
accounting and/or reporting standards.

Audit-Related services are for assurance and related services that are traditionally performed by the independent
registered public accounting firm, including due diligence related to mergers and acquisitions, employee benefit plan
audits and special procedures required to meet certain regulatory requirements.

Tax services include all services, except those services specifically related to the financial statements, performed by the
independent registered public accounting firm’s tax personnel, including tax analysis; assisting with coordination of
execution of tax-related activities, primarily in the area of corporate development; supporting other tax-related regulatory
requirements; tax planning; and tax compliance and reporting.

All Other services are those services not captured in the Audit, Audit-Related or Tax categories.

Prior to engagement, the Audit Committee pre-approves independent registered public accounting firm services within each
category and the fees of each category are budgeted. The Audit Committee requires the independent registered public accounting
firm and management to report actual fees versus the budget periodically throughout the year by category of service. During the
year, circumstances may arise when it may become necessary to engage the independent registered public accounting firm for
additional services not contemplated in the original pre-approval categories. In those instances, the Audit Committee requires
specific pre-approval before engaging the independent registered public accounting firm.

The Audit Committee may delegate pre-approval authority to one or more of its members. The member to whom such authority is
delegated must report, for informational purposes only, any pre-approval decisions to the Audit Committee at its next scheduled
meeting. All of the services in the table below were pre-approved by the Audit Committee.

AUDIT COMMITTEE REPORT

The Audit Committee reviews the Company’s financial reporting process on behalf of the Board. Management has the primary
responsibility for establishing and maintaining adequate internal control over financial reporting, for preparing the financial
statements, and for the reporting process. The Audit Committee members do not serve as professional accountants or auditors,
and their functions are not intended to duplicate or to certify the activities of management and the independent registered public
accounting firm. The Company’s independent registered public accounting firm is engaged to audit and report on the conformity of
the Company’s financial statements to accounting principles generally accepted in the United States and the effectiveness of the
Company’s internal control over financial reporting.

The Audit Committee discussed with the Company’s internal auditors and with KPMG the overall scope and plans for their
respective audits. The Audit Committee also met with the internal auditors and with KPMG, with and without management present,
to discuss the results of their examinations, their evaluations of the Company’s internal controls, and the overall quality of the
Company’s financial reporting.

In this context, the Audit Committee reviewed and discussed with management and the independent registered public accounting
firm the audited financial statements for the year ended December 30, 2023 (the ‘‘Audited Financial Statements’’), management’s
assessment of the effectiveness of the Company’s internal control over financial reporting, and the independent registered public
accounting firm’s evaluation of the Company’s system of internal control over financial reporting. The Audit Committee has
discussed with the independent registered public accounting firm the matters required to be discussed by Public Company
Accounting Oversight Board (the ‘‘PCAOB’’) Auditing Standard No. 1301, Communications with Audit Committees. In addition, the
Audit Committee has received the written disclosures and the letter from the independent registered public accounting firm
required by applicable requirements of the PCAOB regarding the independent registered public accounting firm’s communications
with the Audit Committee concerning independence, and has discussed with the independent registered public accounting firm its
independence.

Based upon the reviews and discussions referred to above, the Audit Committee recommended to the Board that the Audited
Financial Statements be included in the Company’s Annual Report on Form 10-K for the year ended December 30, 2023, for filing
with the Securities and Exchange Commission.

OUR RELATIONSHIPS
CERTAIN RELATIONSHIPS AND RELATED PERSON
TRANSACTIONS

Indemnification Agreements

We have entered into indemnification agreements with our directors and executive officers. These agreements require us to indemnify
these individuals to the fullest extent permitted by Delaware law against liabilities that may arise by reason of their service to us, and to
advance expenses incurred as a result of any proceeding against them as to which they could be indemnified. Insofar as indemnification
for liabilities arising under the Securities Act may be permitted to directors or executive officers, we have been informed that in the
opinion of the SEC such indemnification is against public policy and is therefore unenforceable.

There is currently no pending material litigation or proceeding involving any of our directors, officers or employees for which
indemnification is sought.

Statement of Policy Regarding Transactions with
Related Persons

We have adopted a written statement of policy regarding transactions with related persons, which we refer to as our ‘‘related person
policy.’’ Our related person policy requires that a ‘‘related person’’ (as defined in paragraph (a) of Item 404 of Regulation S-K) must
promptly disclose to our Chief Legal Officer any ‘‘related person transaction’’ (defined as any transaction that is anticipated would be
reportable by us under Item 404(a) of Regulation S-K in which we were or are to be a participant and the amount involved exceeds
$120,000 and in which any related person had or will have a direct or indirect material interest) and all material facts with respect
thereto. The Chief Legal Officer will then promptly communicate that information to our Board. No related person transaction will be
executed without the approval or ratification of an approving body that shall be composed solely of independent directors who are
disinterested in the transaction. Currently, our Board has designated the members of the Audit Committee as the approving body. It is
our policy that directors interested in a related person transaction will recuse themselves from any vote on a related person transaction
in which they have an interest.

the only routine matter to be presented at the Annual Meeting. The other two matters are non-routine and brokers will not be
allowed to vote on this proposal without specific voting instructions from beneficial owners. We do not expect any additional matters
will be brought before the Annual Meeting. However, if other matters are properly presented, the persons named as proxies in the
proxy card or their substitutes will vote in their discretion.

HOW MANY VOTES ARE NEEDED TO APPROVE EACH PROPOSAL?

With respect to the election of directors, a nominee for director shall be elected to the Board by a plurality of the votes cast in
respect of the shares of common stock present in person or represented by proxy at the Annual Meeting and entitled to vote on the
election of directors. A plurality vote requirement means that the director nominees with the greatest number of votes cast ‘‘FOR’’,
even if it is less than a majority, will be elected. You may vote ‘‘FOR’’ or ‘‘WITHHOLD’’ with respect to each nominee. A withhold
vote in the election of directors will have the same effect as an abstention. Neither a withhold vote nor a broker non-vote will affect
the outcome of the election of directors.

The affirmative vote of a majority of the voting power of common stock present in person or represented by proxy and entitled to
vote on the matter is required to (i) ratify the appointment of KPMG as our independent registered public accounting firm and
(ii) approve, on a nonbinding advisory basis, the compensation of our NEOs, as disclosed in this Proxy Statement. You may vote
‘‘FOR,’’ ‘‘AGAINST,’’ or ‘‘ABSTAIN’’ with respect to these matters. For these matters, abstentions are not counted as affirmative
votes but are counted as present at the Annual Meeting and entitled to vote and will have the effect of a vote ‘‘against’’ the matter.
Broker non-votes, if any, will have no effect on the outcome of these matters.

Proxies

WHO IS SOLICITING MY PROXY?

The Board of Summit Materials is soliciting your proxy to vote at the 2024 Annual Meeting of Stockholders.

HOW CAN I REVOKE MY PROXY?

You can revoke your proxy by sending written notice of revocation to our Chief Legal Officer & Secretary at Summit Materials, Inc.,
1801 California Street, Suite 3500, Denver, Colorado 80202, by May 20, 2024.

WHAT IS THE COST OF THIS PROXY SOLICITATION?

The Company will pay the costs of preparing, printing, assembling, and mailing the proxy materials used in the solicitation of
proxies. Solicitation may be made by our directors, officers, and employees by mail, email, telephone, or in person. Those
individuals will receive no additional compensation for solicitation activities. We have hired Georgeson LLC to assist in the
solicitation of proxies, who will receive a fee of $20,000, plus reasonable out of pocket costs and expenses, for its services.
Broadridge Financial Solutions, Inc. will distribute proxy materials to banks, brokers, and other nominees for forwarding to
beneficial owners and will request brokerage houses and other custodians, nominees, and fiduciaries to forward soliciting material
to the beneficial owners of the common stock held on the record date by such persons. We will reimburse brokerage houses and
other custodians, nominees and fiduciaries for their expenses in forwarding solicitation materials.

Getting Our Proxy Statement and Annual Report

HOW CAN I ACCESS PROXY MATERIALS ONLINE?

This Proxy Statement, the accompanying proxy card, and our 2023 Annual Report are being made available to stockholders online
at www.proxyvote.com.

Instead of mailing printed copies of these materials, we will send some of our stockholders a Notice of Internet Availability of Proxy
Materials (‘‘Notice’’). If you received a Notice and would prefer to receive a paper copy of our proxy materials, follow the
instructions included in the Notice to update your preferences. If you elect to receive our future proxy materials electronically, you
will receive access to those materials via e-mail unless and until you elect otherwise.

WHY DID MY HOUSEHOLD RECEIVE A SINGLE SET OF PROXY MATERIALS?

SEC rules permit us to deliver a single copy of our 2023 Annual Report and Proxy Statement to any household at which two or
more stockholders reside if we believe the stockholders are members of the same family. This practice benefits both you and
Summit Materials, as it eliminates duplicate mailings and reduces our printing and mailing costs. Each stockholder will continue to
receive a separate proxy card or voting instruction card.

Your household may have received a single set of proxy materials this year. If you prefer to receive your own copy now or in future
years, please request a duplicate set by phone at 1-866-540-7095, online at www.proxyvote.com, or by writing to Summit
Materials, c/o Broadridge, 51 Mercedes Way, Edgewood, NY 11717.

If you hold your stock in street name, you may receive some duplicate mailings. Certain brokers will eliminate duplicate account
mailings on request. You may need to contact your broker directly if you want to discontinue duplicate mailings to your household.
You can also register to receive all future stockholder communications electronically, instead of in print. This means that links to the
annual report, proxy statement, and other correspondence will be delivered to you via e-mail. Holders in street name can register
for electronic delivery directly with their bank, brokerage firm, or other nominee. Electronic delivery of stockholder communications
helps save the Company money by reducing printing and postage costs.

Future Shareholder Proposals and Nominations

RULE 14A-8 SHAREHOLDER PROPOSAL

Under SEC rules, if you want us to include a proposal in our proxy statement for the 2025 Annual Meeting of Stockholders, we
must receive your proposal, submitted in writing to our Chief Legal Officer & Secretary, at Summit Materials, Inc., 1801 California
Street, Suite 3500, Denver, Colorado 80202, by December 9, 2024. Any such proposal should comply with the requirements of
Rule 14a-8 promulgated under the Securities Exchange Act. The submission of a shareholder proposal does not guarantee that it
will be included in our proxy statement.

PROXY ACCESS NOMINATIONS AND OTHER PROPOSALS/NOMINATIONS

Under our Bylaws, a stockholder wishing to bring director nominations or other business before an annual meeting is required to
provide advance written notice to the Chief Legal Officer & Secretary of Summit Materials regarding such nominations or other
business and provide the information and satisfy the other requirements set forth in the Bylaws. To be timely, a stockholder who
intends to present nominations or a proposal at the 2025 Annual Meeting other than pursuant to Rule 14a-8 must provide the
information set forth in the Bylaws no earlier than January 21, 2025 and no later than February 20, 2025. However, if we hold the
2025 Annual Meeting more than 30 days before, or more than 70 days after, the anniversary of the 2024 Annual Meeting date, then
the information must be received no earlier than the 120th day prior to the 2025 Annual Meeting date, and not later than the close
of business on the later of the 90th day prior to the 2025 Annual Meeting date or the tenth day after public announcement of the
2025 Annual Meeting date. These advance notice provisions do not apply if the stockholder only seeks to include such matters in
the proxy statement pursuant to Rule 14a-8.

If a stockholder fails to meet these deadlines and fails to satisfy the requirements of Rule 14a-4 under the Securities Exchange Act,
we may exercise discretionary voting authority under proxies we solicit to vote on any such proposal as we determine appropriate.
We also reserve the right to reject, rule out of order, or take other appropriate action with respect to any nomination or proposal that
does not comply with these and other applicable requirements.

EXPLANATORY NOTE

This annual report on Form 10-K (this “report”) is a combined annual report being filed separately by two registrants: 

Summit Materials, Inc. and Summit Materials, LLC. Each registrant hereto is filing on its own behalf all of the information 
contained in this report that relates to such registrant. Each registrant hereto is not filing any information that does not relate to 
such registrant, and therefore makes no representation as to any such information. We believe that combining the annual reports 
on Form 10-K of Summit Materials, Inc. and Summit Materials, LLC into this single report eliminates duplicative and 
potentially confusing disclosure and provides a more streamlined presentation since a substantial amount of the disclosure 
applies to both registrants.

Unless stated otherwise or the context requires otherwise, references to “Summit Inc.” mean Summit Materials, Inc., a 

Delaware corporation, and references to “Summit LLC” mean Summit Materials, LLC, a Delaware limited liability company. 
The references to Summit Inc. and Summit LLC are used in cases where it is important to distinguish between them. We use the 
terms “we,” “our,” “Summit Materials” or “the Company” to refer to Summit Inc. and Summit LLC together with their 
respective subsidiaries, unless otherwise noted or the context otherwise requires.

Summit Inc. was formed on September 23, 2014 to be a holding company. As of December 30, 2023, its sole material 

asset was a 99.4% economic interest in Summit Materials Holdings L.P. (“Summit Holdings”). Summit Inc. has 100% of the 
voting rights of Summit Holdings, which is the indirect parent of Summit LLC. Summit LLC is a co-issuer of our outstanding 6 
1/2% senior notes due 2027 (“2027 Notes”), our 5 1/4% senior notes due 2029 (“2029 Notes”) and our 7 1/4% senior notes due 
2031 (“2031 Notes” collectively with the 2027 Notes, 2029 Notes and 2031 Notes, the “Senior Notes”). Summit Inc.’s only 
revenue for the year ended December 30, 2023 was that generated by Summit LLC and its consolidated subsidiaries. Summit 
Inc. controls all of the business and affairs of Summit Holdings and, in turn, Summit LLC.

DISCLOSURE REGARDING FORWARD-LOOKING STATEMENTS

This report includes “forward-looking statements” within the meaning of the federal securities laws, which involve 

risks and uncertainties. Forward-looking statements include all statements that do not relate solely to historical or current facts, 
and you can identify forward-looking statements because they contain words such as “believes,” “expects,” “may,” “will,” 
“should,” “seeks,” “intends,” “trends,” “plans,” “estimates,” “projects” or “anticipates” or similar expressions that concern our 
strategy, plans, expectations or intentions. All statements made relating to our estimated and projected earnings, margins, costs, 
expenditures, cash flows, growth rates and financial results are forward-looking statements. These forward-looking statements 
are subject to risks, uncertainties and other factors that may cause our actual results, performance or achievements to be 
materially different from future results, performance or achievements expressed or implied by such forward-looking statements. 
We derive many of our forward-looking statements from our operating budgets and forecasts, which are based upon many 
detailed assumptions. While we believe that our assumptions are reasonable, it is very difficult to predict the effect of known 
factors, and, of course, it is impossible to anticipate all factors that could affect our actual results. 

Some of the important factors that could cause actual results to differ materially from our expectations are disclosed 

under “Risk Factors” and elsewhere in this report. All subsequent written and oral forward-looking statements attributable to us, 
or persons acting on our behalf, are expressly qualified in their entirety by these cautionary statements.

We undertake no obligation to publicly update or revise any forward-looking statement as a result of new information, 

future events or otherwise, except as otherwise required by law.

As used in this report, unless otherwise noted or the context otherwise requires:

ITEM 1. 

BUSINESS. 

Overview

PART I 

Summit’s vision is to be the most socially responsible, integrated construction materials solution provider, 
collaborating with stakeholders to deliver differentiated innovations and solve our customers’ challenges. Within our markets, 
we strive to be a market leader by offering customers a single-source provider for construction materials and related vertically 
integrated downstream products. Our materials include aggregates, which we supply across the United States, and in British 
Columbia, Canada, and cement, which we supply to surrounding states along the Mississippi River from Minnesota to 
Louisiana. In addition to supplying aggregates to customers, we use a portion of our materials internally to produce ready-mix 
concrete and asphalt paving mix, which may be sold externally or used in our paving and related services businesses. Our 
vertically integrated business model creates opportunities to increase aggregates volumes, optimize margin at each stage of 
production and provide customers with efficiency gains, convenience and reliability, which we believe gives us a competitive 
advantage.

In January 2024, Summit completed a merger with Argos North America Corporation (“Argos USA”), Cementos 

Argos S.A., Argos SEM LLC and Valle Cement Investments, Inc., pursuant to which Summit acquired all of the outstanding 
equity interests (the “Transaction”) of Argos USA from the Argos SEM LLC and Valle Cement Investments, Inc. in exchange 
for $1.2 billion of cash, the issuance of 54,720,000 shares of our Class A common stock and one preferred share in a transaction 
valued at approximately $3.2 billion. The cash consideration was funded from the net proceeds of an $800 million offering of 
Senior Notes due 2031 and new term loan borrowings under our current credit facility. The purchase price is subject to 
customary adjustments, with any upward or downward adjustments made against the cash consideration. The Transaction 
Agreement, dated as of September 7, 2023 (the “Transaction Agreement”) relating to the Transaction contains customary 
representations and warranties, covenants and agreements, including entry into a stockholder agreement. 

The Argos USA assets include four integrated cement plants, two grinding facilities, 140 ready-mix concrete plants, 

eight ports and 10 inland terminals across the East and Gulf Coast regions, with a total installed cement grinding capacity of 9.6 
million tons per annum and a total import capacity of 5.4 million tons of cement per annum. The import facilities allow the 
importing of cement from other countries, including a minimum quantity from a cement plant in Cartagena, Colombia, owned 
by Cementos Argos S.A., as stipulated under a cement supply agreement entered into upon closing the Transaction. The Argos 
USA assets also include 1.2 billion tons of reserves and resources in four quarries.

For the year ended December 31, 2023, Argos USA sold approximately 6.7 million tons of cement and 5.2 million 

yards of ready-mix concrete, recognizing approximately $1.7 billion of revenue.

We are a major participant in the U.S. construction materials industry. Including the operations of Argos USA 
acquired in January 2024, we believe our sales volumes put us in the top 6 of aggregates suppliers, the top 4 of cement 
producers and we are a major producer of ready-mix concrete and asphalt paving mix. Summit's aggregates reserves and 
resources were 5.5 billion tons as of December 30, 2023. In the year ended December 30, 2023, Summit sold 58.4 million tons 
of aggregates, 2.4 million tons of cement, 4.9 million cubic yards of ready-mix concrete and 3.7 million tons of asphalt paving 
mix across our nearly 400 sites and plants.

The U.S. private construction market and public infrastructure spending has been a steady contributor to overall 
construction market growth. We are well positioned to expand our business by capitalizing on growth in the construction 
market, but economic conditions could challenge our industry growth and, as a result, our growth plans.

Our revenue in 2023 was $2.6 billion with net income attributable to Summit Inc. of $285.9 million. As of December 

30, 2023, our total indebtedness outstanding was approximately $2.3 billion.

We anticipate demand to vary by end market. Public infrastructure, which includes spending by federal, state and local 

governments for roads, highways, bridges, airports and other public infrastructure projects, has been a relatively stable portion 
of government budgets providing consistent demand to our industry and is projected by the Portland Cement Association 
(“PCA”) to grow approximately 4% in the U.S. from 2024 to 2028. By fiscal year 2026, The Infrastructure Investment and Jobs 
Act (the "IIJA") will provide $44.5 billion in formula funding to Texas, Utah, Missouri and Kansas, our top four states by 
revenue in 2023. Further, the IIJA will provide $66.9 billion in formula funding to Florida, Georgia, Texas and North Carolina, 
the top four states by revenue for Argos USA the year ended December 31, 2023. We believe states will continue to institute 
state and local level funding initiatives dedicated towards increased infrastructure spending. Historically, infrastructure 
spending has varied by geography depending on several factors including population growth, underlying economic conditions, 

8

 
 
 
 
 
and fiscal health of individual states. Economic conditions in our markets do vary by state, and public infrastructure funding is 
expected to differ as a result. The public infrastructure market represented approximately 38% of our revenue in 2023.

The private construction market includes residential and nonresidential new construction and the repair and replace 
market. According to the PCA, the number of total housing starts in the United States, a leading indicator for our residential 
business, is expected to increase 25% from 2024 to 2028 and residential construction spending will increase 19% from 2024 to 
2028. Unlike the expected increases in residential construction, the PCA projects that spending in private nonresidential 
construction will decline 9% from 2024 to 2028. Residential activity in our key markets will continue to be a driver for volumes 
in future periods. Growth in private construction spending is influenced by changes in population, employment and general 
economic activity, among other factors which vary by geography across the United States. The private construction market 
represented approximately 62% of our revenue in 2023.

We expect continued improvement in pricing, especially in our materials businesses. The United States Geological 

Survey ("USGS") reports that aggregates pricing has increased in 70 of the last 75 years. Accordingly, we believe that this trend 
will continue in the future. The PCA estimates that cement consumption will increase approximately 10% in the U.S. from 2024 
to 2028, reflecting rising demand in the major end markets. We believe that the increased demand will support higher cement 
pricing as production capacity in the United States remains tight and the cost of imported cement remains high.

We have supplemented organic growth with acquisitions by strategically targeting attractive, new markets and 

expanding in existing markets. We consider population trends, employment rates, private and public construction outlook, 
public funding and various other factors prior to entering a new market. In addition to considering macroeconomic data, we 
seek to establish, and generally believe that we have, a top three position in our local markets, which we believe supports 
improving profit margins and sustainable organic growth. This positioning provides local economies of scale and synergies, 
which benefits our profitability. 

Significant opportunities remain for growth through acquisitions. We estimate that approximately 65% of the U.S. 

construction materials market is privately owned. Our management team maintains contact with hundreds of private companies. 
These long-standing relationships have been the primary source for our past acquisitions and will continue to be an important 
source for future acquisitions. We believe we offer a compelling value proposition for private company sellers, including secure 
ongoing stewardship of their legacy businesses and brands.

We also seek greenfield development opportunities, particularly in our current geographies where there are limited 

additional acquisition opportunities at reasonable values. While greenfield development opportunities generally take longer to 
reach positive cash flows, the return on investment can equal or exceed those of business acquisitions.

In March 2021, we launched our Elevate Summit strategy, which at that time included an initiative to divest 10 to 12 
business units which did not meet certain criteria. Since that time, we have divested 13 businesses, including two businesses in 
2023 that resulted in net proceeds of $65.6 million, and cumulatively the 13 divested businesses generated $567.0 million in net 
proceeds. We plan to continue our efforts to optimize our portfolio, which could include future divestitures.

Our Business Segments

As of December 30, 2023, we operate in 21 U.S. states and in British Columbia, Canada and have assets in 21 U.S. 

states and in British Columbia, Canada through our platforms that make up our operating segments: West, East and Cement. In 
addition, the Argos USA operations acquired subsequent to year end added operations in 18 states and assets in five states. The 
platform businesses in the West, East and Cement segments have their own management teams that are responsible for 
overseeing local operations, implementing commercial and operational best practices, developing growth opportunities and 
integrating acquired businesses. We seek to enhance value through increased scale, efficiencies and cost savings within local 
markets.

• West Segment:  Our West segment is comprised of our West and South regions, and includes operations in Texas, 
Utah, Arizona, Colorado, Idaho, Wyoming, Oklahoma, Arkansas and British Columbia, Canada. We supply 
aggregates, ready-mix concrete, asphalt paving mix and paving and related services in the West segment. As of 
December 30, 2023, the West segment controlled approximately 1.7 billion tons of aggregates reserves and resources 
and $871.5 million of net property, plant and equipment and inventories (“hard assets”). During the year ended 
December 30, 2023, approximately 61% of our revenue was generated in the West segment.

•

East Segment:  Our East segment is comprised of our East and Central regions, and serves markets extending across 
the Midwestern and Eastern United States, most notably in Kansas, Missouri, Virginia, Florida, North Carolina, South 
Carolina, Georgia and Nebraska where we supply aggregates, ready-mix concrete, asphalt paving mix and paving and 

9

 
 
 
 
 
 
related services. As of December 30, 2023, the East segment controlled approximately 3.3 billion tons of aggregates 
reserves and resources and $695.1 million of hard assets. During the year ended December 30, 2023, approximately 
25% of our revenue was generated in the East segment. The Argos USA operations acquired subsequent to year end 
serves markets extending across the Southeast United States, notably in Florida, Georgia, South Carolina, North 
Carolina, Alabama, as well as the Mid-Atlantic United States in Maryland and Virginia.

•

Cement Segment:  Our Cement segment consists of our Hannibal, Missouri and Davenport, Iowa cement plants and 
nine distribution terminals along the Mississippi River from Minnesota to Louisiana. Our highly efficient plants, which 
have converted all production to lower carbon Portland Limestone Cement, are complemented by our integrated 
distribution system that spans the Mississippi River. We process solid and liquid waste into fuel for the plants, which 
can reduce the plants’ fuel costs by up to 50%. The Hannibal, Missouri plant is one of very few cement facilities in the 
United States that can process both hazardous and non-hazardous solid and liquid waste into fuel. As of December 30, 
2023, the Cement segment controlled approximately 0.5 billion tons of aggregates reserves and resources, which serve 
its cement business, and $615.8 million of hard assets. During the year ended December 30, 2023, approximately 15% 
of our revenue was generated in the Cement segment. The Argos USA operations acquired subsequent to year end 
includes four cement plants located in Harleyville, South Carolina; Roberta, Alabama; Newberry, Florida; and 
Martinsburg, West Virginia and two grinding facilities in Atlanta, Georgia and Tampa, Florida.

Our End Markets

Public Infrastructure.  Public infrastructure construction includes spending by federal, state and local governments for 
highways, bridges, airports, schools, public buildings and other public infrastructure projects. Public infrastructure spending has 
historically been more stable than private sector construction. Historically, public infrastructure spending has been less sensitive 
to interest rate changes and economic cycles and often is supported by multi-year federal and state legislation and programs. A 
significant portion of our revenue is derived from public infrastructure projects. As a result, the supply of federal and state 
funding for public infrastructure highway construction significantly affects our public infrastructure end-use business.

Federal infrastructure funds are allocated to the states, which are required to match a portion of the federal funds they 
receive. Federal highway spending uses funds predominantly from the Federal Highway Trust Fund, which derives its revenue 
from taxes on diesel fuel, gasoline and other user fees. The dependability of federal funding allows the state departments of 
transportation to plan for their long-term highway construction and maintenance needs. The IIJA was signed into law on 
November 15, 2021. The IIJA legislation provides $1.2 trillion in funding over five years from 2022 through 2026, which 
includes $347.8 billion for highways, and $91.2 billion for transit.

Residential Construction.  Residential construction includes single family homes and multi-family units such as 

apartments and condominiums. Demand for residential construction is influenced primarily by employment prospects, new 
household formation and mortgage interest rates.  In recent years, we have observed migration trends towards rural and exurban 
U.S. markets, notably in our Texas and Utah markets. In 2023, primarily due to higher interest rates and, by extension, 
affordability challenges, the residential construction market slowed. We expect the demand for residential construction to 
continue to be influenced by mortgage rates in 2024.

Nonresidential Construction.  Nonresidential construction encompasses all privately financed construction other than 

residential structures. Demand for nonresidential construction is customarily driven primarily by population and economic 
growth, and activity tends to follow residential activity by 12-24 months. Population growth generally spurs demand for stores, 
shopping centers and restaurants. Economic growth typically creates demand for projects such as hotels, office buildings, 
warehouses and factories, although growth rates vary across the U.S. The supply of nonresidential construction projects is also 
affected by other variables, including interest rates and the availability of credit to finance these projects.

Our Competitive Strengths

Leading market positions.  We seek to obtain a top two leadership position in our local market areas. Including the 

operations of Argos USA acquired in January 2024, we believe we are a top 6 supplier of aggregates, a top 4 producer of 
cement and a major producer of ready-mix concrete and asphalt paving mix in the United States by volume. We generally focus 
on acquiring aggregate-based companies that have leading local market positions, which we seek to enhance by building scale 
through additional bolt-on acquisitions. The construction materials industry is highly local in nature due to transportation costs 
from the high weight-to-value ratio of the products. Given this dynamic, achieving local market scale provides a competitive 
advantage that drives growth and profitability for our business. Our ability to prudently acquire, rapidly integrate and improve 
multiple businesses has enabled, and will continue to enable, our market leadership.

10

 
 
 
 
 
 
 
 
 
Vertically-integrated business model.  We generate revenue across a spectrum of related products and services. In 
2023, approximately 17% of the aggregates used in our products and services were internally supplied. When and where it's 
advantageous, we employ a vertically-integrated business model operating as a single source provider of materials and paving 
and related services. This approach creates cost, convenience and reliability advantages for our customers, while at the same 
time creating significant cross-marketing opportunities among our interrelated businesses. We believe this creates opportunities 
to increase aggregates volumes, optimize margin at each stage of the value chain, foster more stable demand for aggregates 
through a captive demand outlet, create a competitive advantage through the efficiency gains, convenience and reliability 
provided to customers and enhance our acquisition strategy by providing a greater population of target companies.

Attractive diversity, scale and product portfolio.  We operate in dozens of metropolitan statistical areas across 21 U.S. 

states and in British Columbia, Canada. In the year ended December 30, 2023, 53% of our operating income increase came 
from the West segment, 21% from East segment and 26% from the Cement segment, excluding corporate charges. As of 
December 30, 2023, we had 3.9 billion tons of proven and probable mineral reserves and 1.4 billion tons of measured and 
indicated mineral resources. We estimate that the useful life of our reserves serving our aggregates and cement businesses are 
approximately 55 years and 170 years, respectively, based on the average production rates in 2023 and 2022. The Argos USA 
operations acquired subsequent to year end were located in an additional 18 states and added 0.7 billion tons of proven and 
probable mineral reserves and 0.5 billion tons of measured and indicated mineral resources.

Our dry process cement plants in Hannibal, Missouri and Davenport, Iowa were commissioned in 2008 and 1981, 

respectively. These low-cost cement plants have efficient manufacturing capabilities and are strategically located on the 
Mississippi River and complemented by an extensive network of river and rail fed distribution terminals. Our terminal network 
can accept imported cement to supplement our internal production capacity as demand and market conditions dictate. Due to the 
location of our Hannibal and Davenport plants on the Mississippi River, in 2023, we shipped approximately 70-80% of our 
cement by barge, which is more cost-effective than truck or rail transport.

The Argos USA operations acquired subsequent to year end have four cement plants in Harleyville, South Carolina; 

Roberta, Alabama; Newberry, Florida; and Martinsburg, West Virginia and two grinding facilities in Atlanta, Georgia and 
Tampa, Florida. The total clinker capacity at the plants is 5.2 million tons per annum. Each of the plants and grinding facilities 
is located near multiple transportation access points, and have rail access at each of the cement plants and grinding facilities. 
The integrated network affords a level of resiliency in dealing with planned and unplanned plant maintenance and shutdowns. 
Their terminal network can accept imported cement to supplement our internal production capacity as demand and market 
conditions dictate.

Proven ability to incorporate new acquisitions and grow businesses.  Since our inception, we have acquired dozens 

of businesses, successfully integrating them into three segments through the implementation of operational improvements, 
industry-proven information technology systems, comprehensive safety and management programs. A typical acquisition and 
subsequent integration generally involve implementing common safety and financial back office systems, driving best practices 
in pricing and productivity. In addition, we seek to leverage scale while maintaining local branding and management decision-
making and providing management support, strategic direction and financial capital for investment. 

Experienced and proven leadership driving organic growth, acquisition and optimization strategy.  Our management 

team, including corporate and regional managers, corporate development, finance and legal executives and other heavy side 
industry operators, has extensive experience in the industry. Our management team has successfully enhanced the operations of 
acquired companies, focusing on scale advantages, cost efficiencies and price optimization to improve profitability and cash 
flow. Our management team has undertaken an optimization process whereby we are disposing of certain assets and businesses 
that are not core to our business, helping our management teams narrow their focus to the highest returning components of our 
business and serve our broader goal of increasing our return on invested capital.

Our Business Strategy

Our materials-led business model creates a distinct competitive advantage to support our growth ambitions.  We 

continue to execute on our Elevate Summit Strategy, which has four key themes:

Market Leadership.  We expect to create sustainable advantages in suburban and exurban communities that enhance 

total shareholder value. Our vertical integration of construction materials, products and services is a significant competitive 
advantage and being materials focused and improving the quality, and sustainability of our earnings will drive share growth in 
existing markets and enable entry into new markets. A significant portion of materials used to produce our products and provide 
services to our customers is internally supplied, which enables us to operate as a single source provider of materials, products 
and paving and related services. This creates cost, convenience and reliability advantages for our customers and enables us to 

11

 
 
 
 
 
 
capture additional value throughout the supply chain, while at the same time creating significant cross-marketing opportunities 
among our interrelated businesses.

Asset Light Approach.  We seek to maximize aggregates pull through in order to improve capital efficiency and 

reduce volatility. Our growth has been a result of the successful execution of our materials-led acquisition strategy and 
implementation of best practices to drive organic growth. We believe we have opportunity for further growth through strategic 
acquisitions in markets adjacent to our existing markets within the states where we currently operate, as well as in additional 
states as market and competitive conditions permit. We also believe we can enhance our return on investment by partnering 
with our customers in asset light partnerships by retaining aggregate supply agreements where possible.

Social Responsibility.  We strive to build differentiated, heavy materials solutions to enhance returns and maximize 

social impact. As our customers focus on their own social responsibility goals, we plan to provide innovative solutions to meet 
those goals. We view social responsibility, which includes human capital, land use, water and addressing carbon emissions 
impacts, as a strategic imperative essential to serving the needs of our employees, customers, and communities where we 
operate. We publish an annual sustainability report aligned with the Sustainability Accounting Standards Board Construction 
Materials Standard. Our sustainability report describes our safety performance as well as water usage, waste production, and 
carbon emissions impacts. We seek to proactively address those impacts to align our business activities with the interests of our 
external stakeholders.

Innovation Focus.  We seek to make investments to address tomorrow's customer challenges with new products and 

solutions. We seek to enhance margins through proven profit optimization plans, managed working capital and achieved 
scale-driven purchasing synergies and fixed overhead control and reduction. Our management team, supported by our 
operations, development, risk management, information technology and finance teams, drive the implementation of detailed and 
thorough profit optimization plans for each acquisition post close. These integration and improvement plans typically include, 
among other things, implementation of a common pricing strategy, safety and financial systems, systematic commercial 
strategies, operational benefits, efficiency improvement plans and business-wide cost reduction techniques. In addition, through 
our portfolio optimization program, we are also evaluating and executing on divestitures of certain assets and businesses that 
are not core to our business or have underperformed our investment expectations.

Our Industry

The U.S. construction materials industry is composed of four primary sectors: aggregates; cement; ready-mix concrete; 

and asphalt paving mix. Each of these materials is widely used in most forms of construction activity. Participants in these 
sectors typically range from small, privately-held companies focused on a single material, product or market to publicly traded 
multinational corporations that offer a wide array of construction materials and services. The industry is shaped in part by the 
distance materials can be transported efficiently, resulting in primarily local or regional operations. Due to the lack of product 
differentiation, competition for all of our products is predominantly based on price and, to a lesser extent, quality of products 
and service. Accordingly, our profitability is generally dependent on the level of demand for our materials and products and our 
ability to control operating costs.

Transportation infrastructure projects, driven by both federal and state funding programs, represent a significant share 
of the U.S. construction materials market. Federal funds are allocated to the states, which are required to match a portion of the 
federal funds they receive. Federal highway spending primarily uses funds from the Federal Highway Trust Fund, which 
derives its revenue from taxes on diesel fuel, gasoline and other user fees. The dependability of federal funding allows the state 
departments of transportation to plan for their long-term highway construction and maintenance needs. The IIJA passed in 
November 2021 provides $1.2 trillion in funding over five years from 2022 through 2026, which includes $347.8 billion for 
highways, and $91.2 billion for transit.

In addition to federal funding, state, county and local agencies provide highway construction and maintenance funding. 

Our four largest states by revenue, Texas, Utah, Missouri and Kansas, represented approximately 26%, 14%, 10% and 8%, 
respectively, of our total revenue in 2023. Further, the four largest states by revenue in 2023 for the Argos USA operations 
acquired subsequent to year end were Florida, Georgia, Texas and North Carolina.

Our Industry and Operations

We do not believe that increases in our prices of materials or products are likely to affect the decision to undertake a 

construction project since these costs usually represent a small portion of total construction costs.

We operate our construction materials, products and paving and related services businesses through local management 
teams, which work closely with our customers to deliver the materials, products and services that meet each customer’s specific 

12

 
 
 
 
 
 
needs for a project. We believe that this strong local branding presence gives us a competitive advantage by allowing us to 
obtain a unique understanding of the evolving needs of our customers.

We have operations in 21 U.S. states and in British Columbia, Canada. The Argos USA operations acquired 
subsequent to year end were located in an additional 18 states. Our business in each region is vertically-integrated. We supply 
aggregates internally for the production of cement, ready-mix concrete and asphalt paving mix and a significant portion of our 
asphalt paving mix is used internally by our paving and related services businesses. In the year ended December 30, 2023, 
approximately 83% of our aggregates production was sold directly to outside customers with the remaining amount being 
further processed by us and sold as a downstream product. In addition, we operate a municipal waste landfill in our East 
segment and have construction and demolition debris landfills in our West and East segments.

Approximately 65% of our asphalt paving mix was installed by our paving and related services businesses in the year 

ended December 30, 2023. We charge a market price and competitive margin at each stage of the production process in order to 
optimize profitability across our operations. Our production value chain is illustrated as follows:

Aggregates

Aggregates are key material components used in the production of cement, ready-mix concrete and asphalt paving 

mixes for the public infrastructure, residential and nonresidential end markets and are also widely used for various applications 
and products, such as road and building foundations, railroad ballast, erosion control, filtration, roofing granules and in 
solutions for snow and ice control. Generally extracted from the earth using surface or underground mining methods, 
aggregates are produced from natural deposits of various materials such as limestone, sand and gravel, granite and trap rock. 
Aggregates are produced mainly from blasting hard rock from quarries and then crushing and screening it to various sizes to 
meet our customers’ needs. The production of aggregates also involves the extraction of sand and gravel, which requires less 
crushing, but still requires screening for different sizes. Aggregate production utilizes capital intensive heavy equipment which 
includes the use of loaders, large haul trucks, crushers, screens and other heavy equipment at quarries and sand and gravel pits. 
Once extracted, processed and/or crushed and graded on-site into crushed stone, concrete and masonry sand, specialized sand, 
pulverized lime or agricultural lime, they are supplied directly to their end use or incorporated for further processing into 
construction materials and products, such as cement, ready-mix concrete and asphalt paving mix. The minerals are processed to 
meet customer specifications or to meet industry standard sizes. Crushed stone is used primarily in ready-mix concrete, asphalt 
paving mix, and the construction of road base for highways.

As of December 30, 2023, we mine limestone, gravel, and other natural resources from 128 crushed stone quarries and 
109 sand and gravel deposits throughout the United States and in British Columbia, Canada. Our extensive network of quarries, 
plants and facilities, located throughout the regions in which we operate, enables us to have a nearby operation to meet the 
needs of customers in each of our markets. As of December 30, 2023, we had approximately 5.5 billion tons of reserves and 
resources of recoverable stone, and sand and gravel of suitable quality for economic extraction. Our estimate is based on 
drilling and studies by geologists and engineers, recognizing reasonable economic and operating restraints as to maximum 
depth of extraction and permit or other restrictions. Reported proven and probable reserves include only quantities that are 

13

 
 
 
 
 
owned or under lease, and for which all required zoning and permitting have been obtained. Of the 5.5 billion tons of 
aggregates reserves and resources, 2.4 billion, or 44%, are located on owned land and 3.1 billion are located on leased land.

As of December 31, 2023, the Argos USA operations acquired subsequent to year end include mine limestone from 

four crushed stone quarries in Harleyville, South Carolina, Newberry, Florida, Roberta, Alabama and Martinsburg, West 
Virginia. These quarries are located throughout the regions in which Argos USA operates, and provide a nearby operation to 
meet the needs of customers in each of those markets. As of December 31, 2023, Argos USA had approximately 1.2 billion tons 
of reserves and resources of recoverable stone of suitable quality for economic extraction. The estimate is based on drilling and 
studies by geologists and engineers, recognizing reasonable economic and operating restraints as to maximum depth of 
extraction and permit or other restrictions. Reported proven and probable reserves include only quantities that are owned, and 
for which all required zoning and permitting have been obtained. All of the Argos USA reserves and resources acquired in 
January 2024 are located on owned land.

Transportation costs are a major variable in determining the marketing radius for our products. The cost of transporting 
aggregate products from the plant to the market often equates to or exceeds the sale price of the product at the plant. As a result 
of the high transportation costs and the large quantities of bulk material that have to be shipped, finished products are typically 
marketed locally. High transportation costs are responsible for the wide dispersion of production sites. Our transportation costs 
are also increasing, primarily due to driver shortages and elevated fuel costs. Where possible, construction material producers 
maintain operations adjacent to highly populated areas to reduce transportation costs and enhance margins. However, more 
recently, local environmental concerns and a more restrictive permitting and regulatory landscape have been forcing production 
sites to move further away from the end-use locations.

Each of our aggregates operations is responsible for the sale and marketing of its aggregates products. For the year 
ended December 30, 2023, approximately 83% of our aggregates production was sold directly to outside customers and the 
remaining amount is further processed by us and sold as a downstream product. Even though aggregates are a commodity 
product, we work to optimize pricing depending on the site location, availability of a particular product, customer type, project 
type and haul cost. We sell aggregates to internal downstream operations at market prices.

Our competitors in aggregates include large vertically-integrated companies, which have a combined estimated market 

share of approximately 30%, in addition to various local suppliers. 

We have a strong competitive advantage in aggregates through our well-located reserves and assets in key markets, 

high quality reserves and our logistic networks. We further share and implement best practices relating to safety, strategy, sales 
and marketing, production, and environmental and land management. Our local market knowledge enables us to maintain a 
strong understanding of the needs of our aggregates customers. In addition, our companies have a reputation for responsible 
environmental stewardship and land restoration, which assists us in obtaining new permits and new reserves.

Cement

Portland cement, an industry term for the common cement in general use around the world, is made from a 

combination of limestone, shale, clay, silica and iron ore. It is a fundamental building material consumed in several stages 
throughout the construction cycle of public infrastructure, residential and nonresidential projects. It is a binding agent that, 
when mixed with sand or aggregates and water, produces either ready-mix concrete or mortar and is an important component of 
other essential construction materials. Few construction projects can take place without utilizing cement somewhere in the 
design, making it a key ingredient used in the construction industry. The majority of all cement shipments are sent to ready-mix 
concrete operators. Sales are made on the basis of competitive terms and prices in each market. Nearly two-thirds of U.S. 
consumption occurs between May and November, coinciding with end-market construction activity.

Cement production in the United States is distributed from over 90 production facilities located across a majority of 

the states and is a capital-intensive business with variable costs dominated by raw materials and energy required to fuel the kiln. 
Most U.S. cement producers are owned by large foreign companies operating in multiple international markets. Our largest 
competitors include large vertically integrated companies. Construction of cement production facilities is highly capital 
intensive and requires long lead times to complete engineering design, obtain regulatory permits, acquire equipment and 
construct a plant.

We operate a highly-efficient, low-cost integrated cement manufacturing and distribution network through our cement 

plants in Hannibal, Missouri, and Davenport, Iowa and our nine distribution terminals along the Mississippi River from 
Minnesota to Louisiana. The combined potential capacity at our Hannibal and Davenport cement plants is approximately 
2.4 million short tons per annum. We also operate on-site waste fuel processing facilities at the plants, which can reduce plant 

14

 
 
 
 
 
  
 
 
fuel costs by up to 50%. Our Hannibal plant is one of very few with hazardous waste fuel facilities permitted and operating out 
of over 90 cement plants in the United States. Competitive factors include price, reliability of deliveries, location, quality of 
cement and support services. Aligned with our core strategy of sustainability, we converted 100% of our cement production 
from general use Portland cement to Portland Limestone Cement (PLC) during 2022. Portland Limestone Cement is accepted in 
all major specifications, approved in all major markets, can be used in all applications in lieu of Portland cement while reducing 
cement’s embodied CO2 content by up to 10%. With two cement plants, on-site raw material supply, a network of cement 
terminals, and longstanding customer relationships, we are well positioned to serve our customers.

Cement is a product that is costly to transport. Consequently, the radius within which a typical cement plant is 
competitive with truck transportation is typically limited to 150 miles from any shipping/distribution point. However, access to 
rail and barge can extend the distribution radius significantly. With both of our plants located on the Mississippi River, we are 
able to cost effectively distribute cement from both of our plants by truck, rail and barge directly to customers or to our nine 
storage and distribution terminals along the Mississippi River. Our Hannibal and Davenport plants are located on the 
Mississippi River and, consequently, we ship approximately 70-80% cement produced at those locations by barge, which is 
more cost-effective than truck or rail transport.

The majority of U.S. cement plants are subject to the Portland Cement – Maximum Achievable Control Technology 
(“PC-MACT”). Our Hannibal and Davenport cement plants utilize alternative fuels, hazardous and non-hazardous at Hannibal 
and non-hazardous at Davenport, as well as coal, natural gas and petroleum coke and, as a result, are subject to additional 
standards including the Hazardous Waste Combustor – Maximum Achievable Control Technology (“HWC-MACT”) and 
Commercial/Industrial Solid Waste Incinerators (“CISWI”) standards, respectively, rather than PC-MACT standards.

Ready-mix Concrete

Ready-mix concrete is one of the most versatile and widely used materials in construction today. Its flexible recipe 

characteristics allow for an end product that can assume almost any color, shape, texture and strength to meet the many 
requirements of end users that range from bridges, foundations, skyscrapers, pavements, dams, houses, parking garages, water 
treatment facilities, airports, tunnels, power plants, hospitals and schools. The versatility of ready-mix concrete gives engineers 
significant flexibility when designing these projects.

Cement, coarse aggregate, fine aggregate, water and admixtures are the primary ingredients in ready-mix concrete. 

Other materials commonly used in the production of ready-mix concrete include fly-ash, a waste by-product from coal burning 
power plants, silica fume, a waste by-product generated from the manufacture of silicon and ferro-silicon metals, and ground 
granulated blast furnace slag, a by-product of the iron and steel manufacturing process. These materials are available directly 
from the producer or via specialist distributors who intermediate between the ready-mix concrete producers and the users.

We believe our West and East segments are leaders in the supply of ready-mix concrete in their respective markets. 

The West segment has ready-mix concrete operations in the Texas, Utah, Arizona, Idaho, Oklahoma and Colorado markets. Our 
East segment supplies ready-mix concrete in the Kansas and Missouri markets and surrounding areas. The Argos USA 
operations acquired subsequent to year end included ready-mix operations in an additional four states primarily in the Southeast 
United States. We operated 70 ready-mix concrete plants and over 850 concrete delivery trucks in the West segment and 22 
ready-mix concrete plants and over 150 concrete delivery trucks in the East segment as of December 30, 2023. The Argos USA 
operations acquired subsequent to year end include 140 ready-mix concrete plants and over 1000 concrete delivery trucks as of 
December 31, 2023. Our aggregates business serves as the primary source of the raw materials for our concrete production, 
functioning essentially as a supplier to our ready-mix concrete operations. 

Asphalt Paving Mix

Asphalt paving mix is the most common roadway material used today. It is a versatile and essential building material 
that has been used to surface 94% of the more than 2.7 million miles of paved roadways in the United States, according to the 
National Asphalt Pavement Association (“NAPA”).

Typically, asphalt paving mix is placed in three distinct layers to create a flexible pavement structure. These layers 

consist of a base course, an intermediate or binder course, and a surface or wearing course. These layers vary in thickness.

Asphalt pavement is generally 100% recyclable and reusable and is the most reused and recycled pavement material in 

the United States. Reclaimed asphalt pavement can be incorporated into new pavement at replacement rates in excess of 30% 
depending upon the mix and the application of the product. We actively engage in the recycling of previously used asphalt 
pavement and concrete. This material is crushed and repurposed in the construction cycle. As of December 30, 2023, we 

15

 
 
 
 
 
 
 
  
 
operated 25 and 5 asphalt paving mix plants in the West and East segments, respectively. Nearly all of our plants can utilize 
recycled asphalt pavement.

The use of warm mix asphalt (“WMA”) or “green” asphalt is gaining popularity. The immediate benefit to producing 

WMA is the reduction in energy consumption required by burning fuels to heat traditional hot mix asphalt (“HMA”) to 
temperatures in excess of 300°F at the production plant. These high production temperatures are needed to allow the asphalt 
binder to become viscous enough to completely coat the aggregate in the HMA, have good workability during laying and 
compaction, and durability during traffic exposure. According to the Federal Highway Administration, WMA can reduce the 
mixing temperature by 50°F to 70°F, resulting in lower emissions, fumes and odors generated at the plant and the paving site.

Approximately 65% of the asphalt paving mix we produce is installed by our own paving crews. The rest is sold on a 

per ton basis to road contractors, state departments of transportation and local agencies. Asphalt paving mix is used by our 
paving crews and by our customers primarily for the construction of roads, driveways and parking lots.

As part of our vertical integration strategy, we provide asphalt paving and related services to both the private and 
public infrastructure sectors as either a prime or sub-contractor. These services complement our construction materials and 
products businesses by providing a reliable downstream outlet, in addition to our external distribution channels.

Our asphalt paving and related services businesses bid on both private construction and public infrastructure projects 

in their respective local markets. We only provide paving and related services operations as a complement to our aggregates 
operations, which is a major competitive strength. Factors affecting competitiveness in this business segment include price, 
estimating abilities, knowledge of local markets and conditions, project management, financial strength, reputation for quality 
and the availability of machinery and equipment.

Contracts with our customers are primarily fixed price or fixed unit price. Under fixed unit price contracts, we provide 

materials or services at fixed unit prices (for example, dollars per ton of asphalt placed). While the fixed unit price contract 
shifts the risk of estimating the quantity of units required for a particular project to the customer, any increase in our unit cost 
over the bid amount, whether due to inflation, inefficiency, errors in our estimates or other factors, is borne by us unless 
otherwise provided in the contract. Many of our contracts contain adjustment provisions to account for changes in liquid asphalt 
prices.

Customers

Our business is not dependent on any single customer or a few customers. Therefore, the loss of any single or small 

number of customers would not have a material adverse effect on any individual respective market in which we operate or on us 
as a whole. No individual customer accounted for more than 10% of our 2023 revenue.

Seasonality

Use and consumption of our products fluctuate due to seasonality. Nearly all of the products used by us, and by our 

customers, in the private construction or public infrastructure industries are used outdoors. Our highway operations and 
production and distribution facilities are also located outdoors. Therefore, seasonal changes and other weather-related 
conditions, in particular extended rainy and cold weather in the spring and fall and major weather events, such as hurricanes, 
tornadoes, tropical storms, heavy snows, flooding and drought, can adversely affect our business and operations through a 
decline in the use of our products, demand for our services and our ability to provide our products and services. In addition, 
construction materials production and shipment levels follow activity in the construction industry, which typically occurs in the 
spring, summer and fall. Warmer and drier weather during the second and third quarters of our fiscal year typically result in 
higher activity and revenue levels during those quarters. The first quarter of our fiscal year typically has lower levels of activity 
due to weather conditions. The Argos USA operations acquired subsequent to year end will reduce the combined company's 
seasonality due to the majority of Argos USA operations being located in warmer markets. 

Backlog

Our products are generally delivered upon receipt of orders or requests from customers, or shortly thereafter. 

Accordingly, the backlog associated with product sales is converted into revenue within a relatively short period of time. 
Inventory for products is generally maintained in sufficient quantities to meet rapid delivery requirements of customers. 
Therefore, a period over period increase or decrease of backlog does not necessarily result in a material improvement or a 
deterioration of our business. Our backlog includes only those products and projects for which we have obtained a purchase 

16

 
 
 
 
 
 
 
 
 
 
 
order or a signed contract with the customer and does not include products purchased and sold or services awarded and 
provided within the period.

Subject to applicable contract terms, substantially all contracts in our backlog may be canceled or modified by our 

customers. Historically, we have not been materially adversely affected by significant contract cancellations or modifications. 

Intellectual Property

We do not own or have a license or other rights under any patents that are material to our business.

Corporate Information

Summit Materials, Inc. and Summit Materials, LLC were formed under the laws of the State of Delaware on 
September 23, 2014 and September 24, 2008, respectively. Our principal executive office is located at 1801 California Street, 
Suite 3500, Denver, Colorado 80202. Through its predecessor, Summit Inc. commenced operations in 2009 when Summit 
Holdings was formed. Our telephone number is (303) 893-0012.

Human Capital Resources

As of December 30, 2023, we employed approximately 5,300 employees, of which approximately 5,000 were 
employed in the United States with the remainder being employed in Canada. Approximately 77% of our employees are hourly 
workers, with the remainder being salaried. Approximately 9% of our employees are union members, substantially all in our 
cement division and at our Canadian operations, with whom we believe we enjoy a satisfactory working relationship. Our 
collective bargaining agreements for employees who are union members generally expire within three years. Because of the 
seasonal nature of our industry, many of our hourly and certain of our salaried employees are subject to seasonal layoffs. The 
scope of layoffs varies greatly from season to season as they are predominantly a function of the type of projects in process and 
the weather during the late fall through early spring. The Argos USA operations acquired subsequent to year end includes 
approximately 2,400 employees as of December 31, 2023, of which approximately 63% were hourly workers, with the 
remainder being salaried. Approximately 11% of the Argos USA employees are union members.

Health and Safety: We maintain a safety culture grounded on the premise of striving to eliminate workplace 

incidents, risks and hazards. We have created and implemented processes to help eliminate safety events by reducing their 
frequency and severity. We also review and monitor our performance closely. Our goal is to reduce Occupational Safety and 
Health Administration ("OSHA") recordable incidents each year. During fiscal 2023, our recordable incident rate increased 9% 
compared to fiscal 2022.

Inclusion and Diversity: We embrace the diversity of our team members, customers, stakeholders and consumers, 
including their unique backgrounds, experiences, thoughts and talents. Everyone is valued and appreciated for their distinct 
contributions to the growth and sustainability of our business. We strive to cultivate a culture and vision that supports and 
enhances our ability to recruit, develop and retain diverse talent at every level. We have a goal to build a highly engaged team 
by increasing retention year over year. We achieved gender parity at the Board level with over 50% female Board directors.

Talent Development: We prioritize and invest in creating opportunities to help employees grow and build their 

careers, through various training and development programs. These include on-the-job learning formats as well as executive 
talent and succession planning paired with an individualized development approach. 

Compensation and Benefits: In addition to competitive base compensation, we offer incentive plans for both safety 

and operational results, stock awards, a 401(k) plan, healthcare and insurance benefits, health savings and flexible spending 
accounts, paid time off, family leave programs, and employee assistance programs, among other benefits. Our 401(k) plan 
covers all U.S. employees, and provides for matching contributions to the plan, including 100% of pre-tax employee 
contributions, up to 4% of eligible compensation. Employer contributions vest immediately. During 2021, we implemented an 
Employee Stock Purchase Plan in which the majority of our employees are eligible to participate.

Legal Proceedings

We are party to certain legal actions arising from the ordinary course of business activities. While the ultimate results 

of claims and litigation cannot be predicted with certainty, management expects that the ultimate resolution of all current 
pending or threatened claims and litigation will not have a material effect on our consolidated financial condition, results of 
operations or liquidity.

17

 
 
 
 
 
 
 
 
In March 2018, we were notified of an investigation by the Canadian Competition Bureau (the “CCB”) into pricing 

practices by certain asphalt paving contractors in British Columbia, including Winvan Paving, Ltd. (“Winvan”). The 
investigation is focused on time periods prior to our April 2017 acquisition of Winvan and we are cooperating with the CCB. 
Although we currently do not believe this matter will have a material adverse effect on our business, financial condition or 
results of operations, we are currently not able to predict the ultimate outcome or cost of the investigation.

Environmental and Government Regulation

We are subject to federal, state, provincial and local laws and regulations relating to the environment and to health and 
safety, including noise, discharges to air and water, waste management including the management of hazardous waste used as a 
fuel substitute in our cement plants, remediation of contaminated sites, mine reclamation, operation and closure of landfills, 
dust control and zoning, land use and permitting. Our failure to comply with such laws and regulations can result in sanctions 
such as fines or the cessation of part or all of our operations. From time to time, we may also be required to conduct 
investigation or remediation activities. There also can be no assurance that our compliance costs or liabilities associated with 
such laws and regulations or activities will not be significant.

In addition, our operations require numerous governmental approvals and permits. Environmental operating permits 

are subject to modification, renewal and revocation and can require us to make capital, maintenance and operational 
expenditures to comply with the applicable requirements. Stricter laws and regulations, or more stringent interpretations of 
existing laws or regulations, may impose new liabilities on us, reduce operating hours, require additional investment by us in 
pollution control equipment or impede our opening new, expanding or maintaining existing plants or facilities. We regularly 
monitor and review our operations, procedures and policies for compliance with environmental laws and regulations, changes in 
interpretations of existing laws and enforcement policies, new laws that are adopted, and new requirements that we anticipate 
will be adopted that could affect our operations.

Multiple permits are required for our operations, including those required to operate our cement plants, conduct mining 

activities at our aggregate quarries, operate our ready-mixed concrete plants and lay asphalt. Applicable permits may include 
conditional use permits to allow us to operate in certain areas absent zoning approval and operational permits governing, among 
other matters, air and water emissions, dust, particulate matter and storm water management and control. In addition, we are 
often required to obtain bonding for future reclamation costs, most commonly specific to restorative grading and seeding of 
disturbed surface areas.

Like others in our industry, we expend substantial amounts to comply with applicable environmental laws and 

regulations and permit limitations, which include amounts for pollution control equipment required to monitor and regulate 
emissions into the environment. The Hannibal and Davenport cement plants are subject to HWC-MACT and CISWI standards, 
respectively, for which we do not expect any material incremental costs to maintain compliance. Since many environmental 
requirements are likely to be affected by future legislation or rule making by government agencies, and are therefore not 
quantifiable, it is not possible to accurately predict the aggregate future costs of compliance and their effect on our future 
financial condition, results of operations and liquidity.

At most of our quarries, we incur reclamation obligations as part of our mining activities. Reclamation methods and 

requirements can vary depending on the individual site and state regulations. Generally, we are required to grade the mined 
properties to a certain slope and seed the property to prevent erosion. We record a mining reclamation liability in our 
consolidated financial statements to reflect the estimated fair value of the cost to reclaim each property including active and 
closed sites.

Our operations in Kansas include one municipal waste landfill and three construction and demolition debris landfills, 
and in Colorado, we have a construction and demolition debris landfill. In Vancouver, British Columbia, we operate a landfill 
site that accepts environmentally clean soil deposits. Among other environmental, health and safety requirements, we are 
subject to obligations to appropriately close those landfills at the end of their useful lives and provide for appropriate 
post-closure care. Asset retirement obligations relating to these landfills are recorded in our consolidated financial statements.

Health and Safety

Our facilities and operations are subject to a variety of worker health and safety requirements, particularly those 

administered by the federal Occupational Safety and Health Administration (“OSHA”) and Mine Safety and Health 
Administration (“MSHA”). Throughout our organization, we strive for a zero-incident safety culture and full compliance with 
safety regulations. Failure to comply with these requirements can result in sanctions such as fines and penalties and claims for 
personal injury and property damage. These requirements may also result in increased operating and capital costs in the future.

18

 
 
 
 
 
 
 
 
 
Worker safety and health matters are overseen by our corporate risk management and safety department as well as 
operations level safety managers. We provide our operations level safety managers leadership and support, comprehensive 
training, and other tools designed to accomplish health and safety goals, reduce risk, eliminate hazards, and ultimately make our 
work places safer.

RISK FACTORS 

You should carefully consider the following risk factors as well as the other information set forth in this Annual 

Report on Form 10-K (this “Annual Report”), including “Management’s Discussion and Analysis of Financial Condition and 
Results of Operations” and our consolidated financial statements and related notes thereto. If any of the following risks 
actually occurs, our business, results of operations, prospects, and financial condition may be materially adversely affected. In 
such a case, the trading price of our Class A common stock could decline and you may lose all or part of your investment. The 
risks and uncertainties described below are those that we have identified as material but are not the only risks and 
uncertainties we face. Our business is also subject to general risks and uncertainties that affect many other companies, 
including but not limited to overall economic and industry conditions and additional risks not currently known to us or that we 
presently deem immaterial may arise or become material and may negatively impact our business, reputation, financial 
condition, results of operations or the trading price of our Class A common stock. Some statements in this Annual Report, 
including statements in the following risk factors, constitute forward-looking statements. See “Forward-Looking Statements".

Risks Related to Our Industry and Our Business

Industry Risks

Our business depends on activity within the construction industry and the strength of the economies in which we operate.

We sell most of our construction materials and products and provide all of our paving and related services to the 

construction industry, so our results are significantly affected by the strength of the construction industry. The strength of the 
construction industry in turn can be substantially affected by macroeconomic and other factors beyond our control, including 
changes in general economic conditions, political or social trends and unrest, terrorism or war, pandemics or other adverse 
health developments, and natural, climate-related or man-made disasters and extreme weather conditions. In addition, federal 
and state budget issues may negatively affect the amount of funding available for infrastructure spending, particularly highway 
construction, which constitutes a significant portion of our business. Demand for our products, particularly in the residential 
and nonresidential construction markets, could decline if companies and consumers cannot obtain funding for construction 
projects, or due to other market factors such as rising interest rates, labor shortages and inflation which have impacted demand 
more recently and are expected to further impact demand in 2024. A slow pace of economic activity typically results in delays 
or cancellations of capital projects, which could result in the deferral or reduction of our backlog and anticipated revenues if 
we are unable to replace those contracts. In addition, in times of a stagnant or declining economy, there is a greater likelihood 
that we may not be able to collect on certain of our accounts receivable from our customers.

While our business operations cover a wide geographic area, our earnings depend on the strength of the local 

economies in which we operate because of the high cost to transport our products relative to their price. If economic and 
construction activity diminishes in one or more areas, particularly in our top revenue-generating markets of Texas, Florida, 
Georgia and Utah, our financial condition, results of operations and liquidity could be materially adversely affected. 

Our industry is cyclical and requires significant working capital to fund operations.

Our industry is cyclical and requires that we maintain significant working capital to fund our operations. Our ability 

to generate sufficient cash flow depends on future performance, which will be subject to general economic conditions, industry 
cycles and financial, business and other factors affecting our operations, many of which are beyond our control. If we are 
unable to generate sufficient cash to operate our business and service our outstanding debt and other obligations, we may be 
required, among other things, to further reduce or delay planned capital or operating expenditures, sell assets or take other 
measures, including the restructuring of all or a portion of our debt, which may only be available, if at all, on unsatisfactory 
terms.

Weather can materially affect our business and we are subject to seasonality.

The products we sell and the services we provide are used or performed outdoors. Therefore, seasonal changes and 
other weather-related conditions can adversely affect our business and operations through a decline in the use and production 
of our products, demand for our services and our ability to provide our products and services. Adverse weather conditions such 
as heavy or sustained rainy and cold weather in the spring and fall can reduce demand for our products and reduce sales, 
render our contracting operations less efficient or restrict our ability to ship our products. For example, unusually low water 
levels on the Mississippi River in late 2022 negatively impacted the shipping of our products. Major weather events such as 
hurricanes, tornadoes, tropical storms, flooding, droughts, wildfires and heavy snows have adversely affected and could 

20

 
 
 
 
 
 
 
 
adversely affect sales in the near term and may be more severe due to climate change. In particular, our operations in the 
southeastern and Gulf Coast regions of the United States are at risk for hurricane activity, most notably in August, September 
and October. 

Our industry is capital intensive and we have significant fixed and semi-fixed costs. Therefore, our profitability is sensitive 
to changes in volume.

The property and machinery needed to produce our materials and products can be very expensive and can have long 

lead times to acquire. Therefore, we need to spend a substantial amount of capital to purchase and maintain the equipment 
necessary to operate our business. Although we believe that our current cash balance, along with our projected internal cash 
flows and our available financing resources, will provide sufficient cash to support our currently anticipated operating and 
capital needs, if we are unable to generate sufficient cash to purchase and maintain the property and machinery necessary to 
operate our business, we may be required to reduce or delay planned capital expenditures or incur additional debt. In addition, 
given the level of fixed and semi-fixed costs within our business, particularly at our cement production facilities, decreases in 
volumes could have a material adverse effect on our financial condition, results of operations and liquidity.

Within our local markets, we operate in a highly competitive industry.

The U.S. construction aggregates industry is highly fragmented with a large number of independent local producers in 
a number of our markets. Additionally, in most markets, we also compete against large private and public companies, some of 
which are also vertically-integrated. Therefore, there is intense competition in a number of the markets in which we operate. 
This significant competition could lead to lower prices, higher wages, lower sales volumes and higher costs in some markets, 
negatively affecting our financial condition, results of operations and liquidity.

We also face competition for some of our products from alternative products, new product technologies, different 

production and distribution processes and alternative business models. For example, our aggregates, ready mixed concrete, and 
asphalt and paving businesses may compete with recycled asphalt and concrete products that could be used in certain 
applications instead of new products and our cement operations may compete with international competitors who are 
importing products into the United States from jurisdictions with lower production and regulatory costs.

Growth and Portfolio Optimization Risks

The integration of Argos USA may not be as successful as anticipated, and we may not achieve the intended benefits or do 
so within the intended timeframe.

The integration of Argos USA into our business involves numerous operational, strategic, financial, accounting, legal, 

tax and other risks, including potential liabilities associated with the acquired business. Difficulties in integrating the business 
of Argos USA and our ability to manage the post-acquisition company may result in the post-acquisition company performing 
differently than expected, in operational challenges or in the delay or failure to realize anticipated expense-related operating 
synergies and could have an adverse effect on our financial condition, results of operations or cash flows. Potential difficulties 
that may be encountered in the integration process include, among other factors: the inability to successfully integrate the 
businesses of Argos USA, operationally and culturally, in a manner that permits us to achieve the full revenue anticipated; 
complexities associated with managing a larger, more complex, integrated business, including the potential diversion of our 
management's attention; not realizing anticipated operating synergies; the inability to retain key employees and otherwise 
integrate personnel from the two companies and the loss of key employees; potential unknown liabilities and unforeseen 
expenses; integrating relationships with customers, vendors and business partners; performance shortfalls at one or both of the 
companies as a result of the diversion of management's attention caused by integrating Argos USA’s operations; and the 
disruption of, or the loss of momentum in, each company's ongoing business or inconsistencies in standards, controls, 
procedures and policies.

The success of our business depends in part on our ability to execute on our acquisition and portfolio optimization strategy.

A significant portion of our historical growth has occurred through acquisitions, and we will likely execute 

acquisition transactions in the future. Acquisitions involve risks that, among other things, the businesses acquired will not 
perform as expected. We are presently evaluating, and we expect to continue to evaluate on an ongoing basis, possible 
acquisition transactions. We are presently engaged, and at any time in the future we may be engaged, in discussions or 
negotiations with respect to possible acquisitions, including larger transactions that would be significant to us. We regularly 
make, and we expect to continue to make, non-binding acquisition proposals, and we may enter into letters of intent, in each 
case allowing us to conduct due diligence on a confidential basis. In addition, we have recently disposed of a number of assets 
and businesses that did not meet our long-term investment criteria and through our portfolio optimization program, we are also 
evaluating additional divestiture opportunities of certain assets and businesses that are not core to our business. There can be 

21

 
 
 
 
 
 
 
no assurances that we will be able to recover the current carrying amount of our investments, and in some circumstances, 
assets or businesses may result in additional impairment expenses or other losses. In addition, we may become subject to 
certain contractual indemnity or other obligations or may fail to successfully deploy sale proceeds. We cannot predict the 
timing of any contemplated transactions. To successfully acquire a significant target, we may need to raise additional capital 
through additional equity issuances, additional indebtedness, or a combination of equity and debt issuances. There can be no 
assurance that we will enter into definitive agreements with respect to any contemplated transactions or that they will be 
completed. Our acquisitions and portfolio optimization efforts have placed, and may continue to place, significant demands on 
our management and operational and financial resources.

Our results of operations from these acquisitions could, in the future, result in impairment charges for any of our 

intangible assets, including goodwill, or other long-lived assets, particularly if economic conditions worsen unexpectedly. As a 
result of these changes, our financial condition, results of operations and liquidity could be materially adversely affected. In 
addition, many of the businesses that we have acquired and will acquire have unaudited financial statements that have been 
prepared by the management of such companies and have not been independently reviewed or audited. We cannot assure you 
that the financial statements of companies we have acquired or will acquire would not be materially different if such 
statements were independently reviewed or audited. If such statements were to be materially different, the tangible and 
intangible assets we acquire may be more susceptible to impairment charges, which could have a material adverse effect on us.

The success of our business depends on our ability to successfully integrate acquisitions.

Acquisitions may require integration of the acquired companies’ sales and marketing, distribution, production, 

purchasing, information technology, finance and administrative organizations. We may not be able to integrate successfully 
any business we may acquire or have acquired into our existing business and any acquired businesses may not be profitable or 
as profitable as we had expected. Our inability to complete the integration of new businesses in a timely and orderly manner 
could increase costs and lower profits. Factors affecting the successful integration of acquired businesses include, but are not 
limited to, the following: we may become liable for certain, and potentially significant, liabilities of any acquired business, 
whether or not known to us; substantial attention from our senior management and the management of the acquired business 
may be required, which could decrease the time that they have to service and attract customers; capital equipment at acquired 
businesses may require additional maintenance or need to be replaced sooner than we expected; the complete integration of 
acquired companies depends, to a certain extent, on the full implementation of our financial systems and policies; and the 
ability to retain key employees.

Our long-term success is dependent upon securing and permitting aggregate reserves in strategically located areas. The 
inability to secure and permit such reserves could negatively affect our earnings in the future.

Aggregates are bulky and heavy and therefore difficult to transport efficiently. Because of the nature of the products, 

the freight costs can quickly surpass production costs. Therefore, except for geographic regions that do not possess 
commercially viable deposits of aggregates and are served by rail, barge or ship, the markets for our products tend to be 
localized around our quarry sites and are served by truck. New quarry sites often take a number of years to develop. Our 
strategic planning and new site development must stay ahead of actual growth. Additionally, in a number of urban and 
suburban areas in which we operate, it is increasingly difficult to permit new sites or expand existing sites due to community 
resistance. Therefore, our future success is dependent, in part, on our ability to accurately forecast future areas of high growth 
in order to locate optimal facility sites and on our ability to either acquire existing quarries or secure operating and 
environmental permits to open new quarries. If we are unable to accurately forecast areas of future growth, acquire existing 
quarries or secure the necessary permits to open new quarries, our financial condition, results of operations and liquidity could 
be materially adversely affected.

While we perform significant activities around estimating the quantity and quality of our reserves, if those estimates 

of reserve quantities and qualities differ significantly from actual results due to unexpected geological conditions, we may 
exhaust our economically viable aggregates reserves sooner than we expect. If we are unable to acquire replacement aggregate 
reserves, our financial results may be adversely impacted.

Economic Risks

Our business could be impacted by rising interest rates.

Our operations are highly dependent upon the interest rate-sensitive construction industry. Therefore, our business 

may decline as a result of rising interest rates and costs. 

22

 
 
 
 
 
 
 
 
Notably, demand in the residential construction market in which we sell our aggregates and ready-mix concrete is 

affected by interest rates which increased significantly during 2023, impacting demand. There can be no assurance that interest 
rates will not continue to increase in the future, affecting our business in an adverse manner. While the residential construction 
market accounted for 25% of our aggregates business and 45% of our ready-mix concrete business in 2023, we expect demand 
to continue to be impacted by mortgage rates in 2024.

Aside from these inherent risks from within our operations, our earnings are also affected by changes in short-term 

interest rates. However, rising interest rates are not necessarily predictive of weaker operating results.

A decline in public infrastructure construction and reductions in governmental funding could adversely affect our earnings 
in the future.

A significant portion of our revenue is generated from publicly-funded construction projects. As a result, if 
publicly-funded construction decreases due to reduced federal or state funding or otherwise, our financial condition, results of 
operations and liquidity could be materially adversely affected.

Under U.S. law, annual funding levels for highways is subject to yearly appropriation reviews. This annual review of 

funding increases the uncertainty of many state departments of transportation regarding funds for highway projects. This 
uncertainty could result in states being reluctant to undertake large multi-year highway projects which could, in turn, 
negatively affect our sales. We cannot be assured of the existence, amount and timing of appropriations for spending on 
federal, state or local projects. A government shutdown, and other similar budgetary impasses or reductions, may contribute to 
uncertainty in regard to government spending and may have adverse effects on the economy. Federal support for the cost of 
highway maintenance and construction is dependent on congressional action. In addition, each state funds its infrastructure 
spending from specially allocated amounts collected from various taxes, typically gasoline taxes and vehicle fees, along with 
voter-approved bond programs. Shortages in state tax revenues can reduce the amounts spent on state infrastructure projects, 
even below amounts awarded under legislative bills. If state tax revenues Texas, Florida, Georgia and Utah experience 
state-level funding pressures caused by lower tax revenues and an inability to finance approved projects, our revenues could be 
negatively impacted. Delays or cancellations of state infrastructure spending could have a material adverse effect on our 
financial condition, results of operations and liquidity.

Our business relies on private investment in infrastructure, and periods of economic stagnation or recession may adversely 
affect our earnings in the future.

A significant portion of our sales are for projects with non-public owners whose construction spending is affected by 
developers’ ability to finance projects. Residential and nonresidential construction could decline if companies and consumers 
are unable to finance construction projects or in periods of economic stagnation or recession, which could result in delays or 
cancellations of capital projects. If housing starts, particularly in the Houston and Salt Lake City geographies, and 
nonresidential projects stagnate or decline, which in some cases we are already starting to experience, sale of our construction 
materials, downstream products and paving and related services may decline and our financial condition, results of operations 
and liquidity could be materially adversely affected.

Environmental, health and safety laws and regulations and any changes to, or liabilities or litigation arising under, such 
laws and regulations could have a material adverse effect on our financial condition, results of operations and liquidity.

We are subject to a variety of federal, state, provincial and local laws and regulations relating to, among other things: 

(i) the release or discharge of materials into the environment; (ii) the management, use, generation, treatment, processing, 
handling, storage, transport or disposal of hazardous materials, including the management of hazardous and non-hazardous 
waste used as a fuel substitute in our cement kiln in Hannibal, Missouri; (iii) the management, use, generation, treatment, 
processing, handling, storage, transport or disposal of non-hazardous solid waste used as a fuel substitute in our cement kiln in 
Davenport, Iowa; and (iv) the protection of public and employee health and safety and the environment. These laws and 
regulations impose strict liability in some cases without regard to negligence or fault and expose us to liability for the 
environmental condition of our currently or formerly owned, leased or operated facilities or third-party waste disposal sites, 
and may expose us to liability for the conduct of others or for our actions, even if such actions complied with all applicable 
laws at the time these actions were taken. In particular, we may incur remediation costs and other related expenses because our 
facilities were constructed and operated before the adoption of current environmental laws and the institution of compliance 
practices or because certain of our processes are regulated. These laws and regulations may also expose us to liability for 
claims of personal injury or property or natural resource damage related to alleged exposure to, or releases of, regulated or 
hazardous materials. The existence of contamination at properties we own, lease or operate could also result in increased 
operational costs or restrictions on our ability to use those properties as intended.

23

 
 
 
 
 
 
 
 
There is an inherent risk of liability in the operation of our business, and despite our compliance efforts, we may be in 

noncompliance with environmental, health and safety laws and regulations from time to time. These potential liabilities or 
events of noncompliance could have a material adverse effect on our operations and profitability. In many instances, we must 
have government approvals, certificates, permits or licenses in order to conduct our business, which could require us to make 
significant capital, operating and maintenance expenditures to comply with environmental, health and safety laws and 
regulations. Our failure to obtain and maintain required approvals, certificates, permits or licenses or to comply with 
applicable governmental requirements could result in sanctions, including substantial fines or possible revocation of our 
authority to conduct some or all of our operations. Governmental requirements that affect our operations also include those 
relating to air and water quality, waste management, asset reclamation, the operation and closure of municipal waste and 
construction and demolition debris landfills, remediation of contaminated sites and worker health and safety. These 
requirements are complex and subject to frequent change, often in connection with changes in the presidential administration. 
Stricter laws and regulations, more stringent interpretations of existing laws or regulations or the future discovery of 
environmental conditions may impose new liabilities on us, reduce operating hours, require additional investment by us in 
pollution control equipment or impede our opening new or expanding existing plants or facilities.

We have incurred, and may in the future incur, significant capital and operating expenditures to comply with such 

laws and regulations, and in some cases we have been or could be named as a defendant in litigation brought by governmental 
agencies or private parties. In addition, we have recorded liabilities in connection with our reclamation and landfill closure 
obligations, but there can be no assurances that the costs of our obligations will not exceed our estimates. The cost of 
complying with such laws and defending against any litigation could have a material adverse effect on our financial condition, 
results of operations and liquidity.

Shortages of, or increases in prices for, commodities, labor and other production and delivery inputs, including as a result 
of inflation, could restrict our ability to operate our business and could have significant impacts on our operating costs.

Shortages of, or increases in prices for, production and delivery inputs, including commodities and labor, and other 
inputs related to the production and delivery of our products, could adversely affect our business, and have already in certain 
cases. Our cost of revenue consists of production and delivery inputs, which primarily include labor, utilities, raw materials, 
fuel, transportation, royalties and other direct costs incurred in the production and delivery of our products and services. 
Increases in these costs, as a result of general economic conditions, inflationary pressures or otherwise, may reduce our 
operating margin and adversely affect our financial position if we are unable to hedge or otherwise offset such increases. 
Specifically, significant increases or fluctuations in the prices of certain energy commodities, including coal, diesel fuel, 
natural gas, liquid asphalt and other petroleum-based resources, which we consume significant amounts of in our production 
and distribution processes, have negatively affected the results of our business operations and may further cause our results to 
suffer. Additionally, labor is a meaningful component in our ability to operate our business and can have a significant impact 
on the cost of operating our business. Labor shortages could restrict our ability to operate our business or result in increased 
labor costs as a result of wage increases due to competition for qualified workers. Increased labor costs, whether due to labor 
shortages, competition for labor from other industries, changing demographics of the overall work force or otherwise may 
reduce our operating margin and adversely affect our financial position. 

Recent inflation, across several input costs has adversely impacted us. Sustained inflation could result in higher costs 

for transportation, energy, materials, supplies and labor. Our efforts to recover inflation-based cost increases from our 
customers may be hampered as a result of the structure of our contracts and the contract bidding process as well as the 
competitive industries, economic conditions and countries in which we operate. Accordingly, substantial inflation may result 
in a material adverse impact on our costs, profitability and financial results.

Availability of and pricing for raw materials and labor can be affected by various national, regional, local, economic 

and political factors. For example, government-imposed tariffs and trade regulations on imported raw materials could have 
significant impacts on our costs to operate our business, as well as the ongoing labor and supply shortage. 

Financial Risks

If we are unable to accurately estimate the overall risks, requirements or costs when we bid on or negotiate contracts that 
are ultimately awarded to us, we may achieve lower than anticipated profits or incur contract losses.

Even though the majority of our government contracts contain raw material escalators to protect us from certain input 

material price increases, a portion or all of the contracts are often on a fixed cost basis. The costs incurred and profit realized, 
if any, on our contracts can vary, sometimes substantially, from our original projections due to a variety of factors, including, 
but not limited to: failure to include materials or work in a bid, or the failure to estimate properly the quantities or costs needed 
to complete a lump sum contract; delays caused by weather conditions or otherwise failing to meet scheduled acceptance 
dates; contract or project modifications or conditions creating unanticipated costs that are not covered by change orders; 

24

 
 
  
 
 
changes in availability, proximity and costs of materials, including liquid asphalt, cement, aggregates and other construction 
materials (such as stone, gravel, sand and oil for asphalt paving), as well as fuel and lubricants for our equipment; to the extent 
not covered by contractual cost escalators, variability and inability to predict the costs of purchasing coal, diesel, natural gas, 
liquid asphalt and cement; failure by our suppliers, subcontractors, designers, engineers or customers to perform their 
obligations; mechanical problems with our machinery or equipment; difficulties in obtaining required governmental permits or 
approvals; changes in applicable laws and regulations; uninsured claims or demands from third parties for alleged damages 
arising from the design, construction or use and operation of a project of which our work is part; and public infrastructure 
customers may seek to impose contractual risk-shifting provisions more aggressively which may result in us facing increased 
risks.

These factors, as well as others, may cause us to incur losses, which could have a material adverse effect on our 

financial condition, results of operations and liquidity.

We could incur material costs and losses as a result of claims that our products do not meet regulatory requirements or 
contractual specifications.

We provide our customers with products designed to meet building code or other regulatory requirements and 
contractual specifications for measurements such as durability, compressive strength, weight-bearing capacity and other 
characteristics. If we fail or are unable to provide products meeting these requirements and specifications, material claims may 
arise against us and our reputation could be damaged. Additionally, if a significant uninsured, non-indemnified or 
product-related claim is resolved against us in the future, that resolution could have a material adverse effect on our financial 
condition, results of operations and liquidity.

The cancellation of a significant number of contracts or our disqualification from bidding for new contracts could have a 
material adverse effect on our financial condition, results of operations and liquidity.

We could be prohibited from bidding on certain government contracts if we fail to maintain qualifications required by 
the relevant government entities. In addition, contracts with governmental entities can usually be canceled at any time by them 
with payment only for the work completed. A cancellation of an unfinished contract or our disqualification from the bidding 
process could result in lost revenue and cause our equipment to be idled for a significant period of time until other comparable 
work becomes available, which could have a material adverse effect on our financial condition, results of operations and 
liquidity.

Our operations are subject to special hazards that may cause personal injury or property damage, subjecting us to liabilities 
and possible losses, including punitive damages, which may not be covered by insurance.

Operating hazards inherent in our business, some of which may be outside our control, can cause personal injury and 

loss of life, damage to or destruction of property, plant and equipment and environmental damage. We maintain insurance 
coverage in amounts and against the risks that are consistent with industry practice and market availability, but this insurance 
may not be adequate or available to cover all losses or liabilities we may incur in our operations. Our insurance policies are 
subject to varying levels of deductibles. However, liabilities subject to insurance are difficult to estimate due to unknown 
factors, including the severity of an injury, the determination of our liability in proportion to other parties, the number of 
incidents not reported and the effectiveness of our safety programs. If we were to experience insurance claims or costs above 
our estimates, our financial condition, results of operations and liquidity could be materially adversely affected.

Unexpected factors affecting self-insurance claims and reserve estimates could adversely affect our business.

We use a combination of third-party insurance and self-insurance to provide for potential liabilities for workers’ 
compensation, general liability, vehicle accident, property and medical benefit claims. Although we seek to minimize our 
exposure on individual claims, for the benefit of costs savings we have accepted the risk of multiple independent material 
claims occurring. We estimate the projected losses and liabilities associated with the risks retained by us, in part, by 
considering historical claims experience, demographic and severity factors and other actuarial assumptions which, by their 
nature, are subject to a high degree of variability. Among the causes of this variability are unpredictable external factors 
affecting future inflation rates, discount rates, litigation trends, legal interpretations, benefit level changes and claim settlement 
patterns. Any such matters could have a material adverse effect on our financial condition, results of operations and liquidity.

Our debt could adversely affect our financial condition, our ability to raise additional capital to fund our operations, our 
ability to operate our business, our ability to react to changes in the economy or our industry and our ability to pay our 
debts, which could divert our cash flow from operations to debt payments.

25

 
 
 
 
 
 
 
 
 
Our debt level subjects us to risks with important consequences, including: increasing our vulnerability to general 

economic and industry conditions; requiring a significant portion of cash flow from operations to be dedicated to the payment 
of principal and interest on our indebtedness, thereby reducing our ability to use our cash flow to fund our operations, capital 
expenditures and future business opportunities; subjecting us to the risk of increased interest rates as a portion of our 
borrowings under our senior secured credit facilities are exposed to variable rates of interest; restricting us from making 
strategic acquisitions or causing us to make non-strategic divestitures; limiting our ability to obtain additional financing for 
working capital, capital expenditures, debt service requirements, acquisitions and general corporate or other purposes; limiting 
our ability to adjust to changing market conditions and placing us at a competitive disadvantage compared to our competitors 
who have less leverage than we do; and making it more difficult for us to make payments on our debt.

Despite our current level of indebtedness, we and our subsidiaries may still incur substantially more debt. This could 
reduce our ability to satisfy our current obligations and further exacerbate the risks to our financial condition described 
above.

We and our subsidiaries may incur significant additional indebtedness in the future to fund acquisitions as part of our 

growth strategy. Although the indentures governing the Senior Notes and the Credit Agreement contain restrictions on the 
incurrence of additional indebtedness, these restrictions are subject to a number of qualifications and exceptions, and we could 
incur substantial additional indebtedness in compliance with these restrictions.

The indentures governing the Senior Notes and the Credit Agreement contain covenants and provisions that are restrictive.

The indentures governing the Senior Notes and Credit Agreement contain restrictive covenants that, among other 

things, limit our ability, and the ability of our restricted subsidiaries, to: incur additional indebtedness, issue certain preferred 
shares or issue guarantees; pay cash dividends, redeem our membership interests or make other restricted payments, including 
purchasing our Class A common stock; make investments, loans or advances; incur additional liens; transfer or sell assets; 
merge or engage in consolidations; enter into certain transactions with our affiliates; designate subsidiaries as unrestricted 
subsidiaries; repay subordinated indebtedness; and change our lines of business.

The senior secured credit facilities also require us to maintain a maximum first lien net leverage ratio. The Credit 

Agreement also contains certain customary representations and warranties, affirmative covenants and events of default 
(including, among others, an event of default upon a change of control). If an event of default occurs, the lenders under our 
senior secured credit facilities will be entitled to take various actions, including the acceleration of amounts due under our 
senior secured credit facilities and all actions permitted to be taken by a secured creditor. Our failure to comply with 
obligations under the indentures governing the Senior Notes and the Credit Agreement may result in an event of default under 
the indenture or the amended and restated Credit Agreement. A default, if not cured or waived, may permit acceleration of our 
indebtedness. If our indebtedness is accelerated, we may not have sufficient funds available to pay the accelerated 
indebtedness or the ability to refinance the accelerated indebtedness on terms favorable to us or at all.

Other Risks

Our success is dependent on our senior management team and our ability to retain qualified personnel.

Our success depends on the continuing services of key members of our management team. Our senior management 

team possesses valuable knowledge and skills that are crucial to our success and would be difficult to replicate or replace. 

 While we are developing plans for key management succession and have long-term compensation plans designed to 
retain our senior employees, if our retention and succession plans do not operate effectively, our business could be adversely 
affected.

We use large amounts of coal, electricity, diesel fuel, natural gas, liquid asphalt and other petroleum-based resources that 
are subject to potential reliability issues, supply constraints and significant price fluctuation, which could have a material 
adverse effect on our financial condition, results of operations and liquidity.

In our production and distribution processes, we consume significant amounts of electricity, diesel fuel, natural gas, 

liquid asphalt and other petroleum-based resources. The availability and pricing of these resources are subject to market forces 
that are beyond our control. For example, during 2022 the cost of coal, diesel fuel and other petroleum-based resources rose 
sharply. Furthermore, we are vulnerable to any reliability issues experienced by our suppliers, which also are beyond our 
control. Our suppliers contract separately for the purchase of such resources and our sources of supply could be interrupted 

26

 
 
 
 
 
 
 
 
 
 
 
 
should our suppliers not be able to obtain these materials due to higher demand or other factors that interrupt their availability. 
Variability in the supply and prices of these resources could have a material adverse effect on our financial condition, results 
of operations and liquidity.

Climate change and climate change legislation or regulations may adversely affect our business.

A number of governmental bodies have finalized, proposed or are contemplating legislative and regulatory changes in 

response to the potential effects of climate change.

In addition, other potential effects of climate change include physical effects such as disruption in production and 

product distribution as a result of major storm events and shifts in regional weather patterns and intensities. Given the nature 
of our operations, physical impacts may include disruptions in production and/or regional supply or product distribution 
networks due to major storm events, shifts in regional rainfall and temperature patterns and intensities, as well as flooding 
from sea level changes. There is also a potential for climate change legislation and regulation to adversely affect the cost of 
purchased energy and electricity.

The effects of climate change on our operations are highly uncertain and difficult to estimate. However, because a 

chemical reaction inherent to the manufacture of Portland cement releases carbon dioxide, a GHG, cement kiln operations may 
be disproportionately affected by future regulation of GHGs. Climate change and legislation and regulation concerning GHGs 
could have a material adverse effect on our financial condition, results of operations and liquidity.

Our business is subject to evolving corporate governance and corporate disclosure regulations and expectations, including 
with respect to environmental, social and governance matters, that could expose us to numerous risks. 

We are subject to changing rules and regulations promulgated by a number of governmental and self-regulatory 
organizations, including the SEC, the New York Stock Exchange (the "NYSE") and the Financial Accounting Standards 
Board. These rules and regulations continue to evolve in scope and complexity and many new requirements have been created 
in response to laws enacted by Congress, making compliance more difficult and uncertain. In addition, increasingly regulators, 
customers, investors and employees and other stakeholders are focusing on environmental, social and governance (“ESG”) 
matters and related disclosures. These changing rules, regulations and stakeholder expectations have resulted in, and are likely 
to continue to result in, increased general and administrative expenses and increased management time and attention spent 
complying or meeting such regulations and expectations. For example, developing and acting on initiatives within the scope of 
ESG and collecting, measuring, and reporting ESG related information and metrics can be costly, difficult and time consuming 
and is subject to evolving reporting standards, including the SEC’s proposed climate-related reporting requirements, and 
similar proposals by other international regulatory bodies. We may also communicate certain initiatives and goals, regarding 
environmental matters, diversity, responsible sourcing and social investments and other ESG related matters, in our SEC 
filings or in other public disclosures. These initiatives and goals within the scope of ESG could be difficult and expensive to 
implement, the technologies needed to implement them may not be cost effective and may not advance at a sufficient pace, 
and we could be criticized for the accuracy, adequacy or completeness of the disclosure. Further, statements about our ESG-
related initiatives and goals, and progress against these goals, may be based on standards for measuring progress that are still 
developing, internal controls and processes that continue to evolve, and assumptions that are subject to change in the future. In 
addition, we could be criticized for the scope or nature of such initiatives or goals, or for any revisions to these goals. If our 
ESG-related data, processes and reporting are incomplete or inaccurate, or if we fail to achieve progress with respect to our 
goals within the scope of ESG on a timely basis, or at all, our reputation, business, financial performance and growth could be 
adversely affected.

Unexpected operational difficulties at our facilities could disrupt operations, raise costs, and reduce revenue and earnings 
in the affected locations.

The reliability and efficiency of certain of our facilities is dependent upon vital pieces of equipment, such as our 

cement manufacturing kilns. Although we have scheduled outages to perform maintenance on certain of our facilities, vital 
equipment may periodically experience unanticipated disruptions due to accidents, mechanical failures or other unanticipated 
events such as fires, explosions, violent weather conditions or other unexpected operational difficulties. A substantial 
interruption of one of our facilities could require us to make significant capital expenditures to restore operations and could 
disrupt our operations, raise costs, and reduce revenue and earnings in the affected locations.

We may incur significant costs in connection with pending and future litigation.

We have seen increases in litigation as the scope of our business and operations has grown. We are, or may become, 
party to various lawsuits, claims, investigations, and proceedings, including but not limited to personal injury, environmental, 

27

 
 
 
 
 
 
 
antitrust, tax, property entitlements and land use, commercial, contract, product liability, health and safety, and employment 
matters. The outcome of pending or future lawsuits, claims, investigations, or proceedings is often difficult to predict and 
could be adverse and material in amount. Development in these proceedings can lead to changes in management’s estimates of 
liabilities associated with these proceedings including the judge’s rulings or judgments, jury verdicts, settlements, or changes 
in applicable law. Future adverse rulings, settlements, or unfavorable developments could result in charges that could have a 
material adverse effect on our results of operations and cash flows in a particular period. In addition, the defense of these 
lawsuits, claims, investigations, and proceedings may divert our management’s attention, and we may incur significant costs in 
defending these matters. 

We are dependent on information technology. Our systems and infrastructure face certain risks, including cyber security 
risks and data leakage risks.

We are dependent on information technology systems and infrastructure to carry out important operational activities 
and to maintain our business records. In addition, we rely on the systems of third parties, such as third-party vendors. As part 
of our normal business activities, we collect and store certain personal identifying and confidential information relating to our 
customers, employees, vendors and suppliers, and maintain operational and financial information related to our business. We 
may share some of this confidential information with our vendors. We rely on our vendors and third-party service providers to 
maintain effective cybersecurity measures to keep our information secure. Any significant breakdown, invasion, destruction or 
interruption of our existing or future systems by employees, third parties, vendors, others with authorized access to our 
systems, or unauthorized persons could negatively affect operations. In addition, future systems upgrades or changes could be 
time consuming, costly and result in unexpected interruptions or other adverse effects on our business. In addition, cyber-
attacks are continually evolving to become more sophisticated and there is a risk that we could experience a business 
interruption, theft of information or reputational damage as a result of a cyber-attack, such as an infiltration of a data center, 
“ransomware” or other malware, denial-of services attacks, hacking, “phishing” attacks, employee or insider error, 
malfeasance, social engineering, or data leakage of confidential information either internally or at our third-party providers. In 
addition, remote work arrangements for our employees could strain our technology resources and introduce operational risks, 
including heightened cybersecurity risk. These risks have also impacted, and may in the future impact the third parties on 
which we rely, and security measures employed by these third parties may also prove to be ineffective at identifying or 
countering threats. 

While we have invested in the protection of our data and information technology to reduce these risks and 

periodically test the security of our information systems network, there can be no assurance that our efforts will prevent 
breakdowns or breaches in our systems that could have a material adverse effect on our financial condition, results of 
operations and liquidity. Any or our vendors’ and third-party service providers’ failure to maintain the security of the data we 
are required to protect could result in damage to our reputation, financial obligations to third parties, fines, penalties, 
regulatory proceedings and private litigation with potentially large costs, and also in deterioration in customers’ confidence in 
us and other competitive disadvantages. While, to date, we have not had a significant cybersecurity breach or attack that has a 
material impact on our business or results of operations, there can be no assurance that our efforts to maintain the security and 
integrity of our information technology networks and related systems will be effective or that attempted security breaches or 
disruptions would not be successful or damaging.

Our current information technology platforms and systems require periodic updating and maintenance and any failure 

to update or maintain our information technology platforms and systems may have a material adverse effect on our business.  
Further, we also undertake activities to replace our current systems with technology we believe to be superior to our existing 
technology.  The cost and effort to implement such changes may be significant, and may be more than we initially estimate.  
These changes may result in our systems being unavailable from time to time, or may not produce the desired results, which 
may adversely affect our ability to manage and report our results. 

Labor disputes, strikes, other forms of work stoppage or slowdown or other union activities could disrupt operations of our 
businesses.

As of December 30, 2023, labor unions represented approximately 9% of our total employees, substantially all in our 

cement division and at our Canadian operations, and labor unions represented approximately 11% of Argos USA total 
employees. Our collective bargaining agreements for employees generally expire within three years. Although we believe we 
have good relations with our employees and unions, disputes with our trade unions, union organizing activity, or the inability 
to renew our labor agreements or adverse labor relations at any of our locations, could lead to strikes, other forms of work 
stoppage, slowdowns or other actions that could disrupt our operations and, consequently, have a material adverse effect on 
our financial condition, results of operations and liquidity.

Tax increases and changes in tax rules may adversely affect our financial results.

28

 
 
 
 
As a company conducting business with physical operations throughout the United States and Canada, we are 

exposed, both directly and indirectly, to the effects of changes in U.S., state and local tax rules. Taxes for financial reporting 
purposes and cash tax liabilities in the future may be adversely affected by changes in such tax rules. Such changes may put us 
at a competitive disadvantage compared to some of our major competitors, to the extent we are unable to pass the tax costs 
through to our customers.

Organizational Structure Risks

Summit Inc.’s only material asset is its interest in Summit Holdings, and it is accordingly dependent upon distributions 
from Summit Holdings to pay taxes, make payments under the TRA and pay dividends.

Summit Inc. is a holding company and has no material assets other than its ownership of LP Units and has no 
independent means of generating revenue. Summit Inc. intends to cause Summit Holdings to make distributions to holders and 
former holders of LP Units in an amount sufficient to cover all applicable taxes at assumed tax rates, payments under the TRA 
and cash distributions, if any, declared by it. Deterioration in the financial condition, earnings or cash flow of Summit 
Holdings and its subsidiaries for any reason, or restrictions on payments by subsidiaries to their parent companies under 
applicable laws, including laws that require companies to maintain minimum amounts of capital and to make payments to 
stockholders only from profits, could limit or impair their ability to pay such distributions. Additionally, to the extent that 
Summit Inc. needs funds, and Summit Holdings is restricted from making such distributions under applicable law or regulation 
or under the terms of our financing arrangements, or is otherwise unable to provide such funds, it could have a material 
adverse effect on our financial condition, results of operations and liquidity.

Payments of dividends, if any, are at the discretion of our board of directors after taking into account various factors, 
including our business, operating results and financial condition, current and anticipated cash needs, plans for expansion and 
any legal or contractual limitations on our ability to pay dividends. Any financing arrangement that we enter into in the future 
may include restrictive covenants that limit our ability to pay dividends. In addition, Summit Holdings is generally prohibited 
under Delaware law from making a distribution to a limited partner to the extent that, at the time of the distribution, after 
giving effect to the distribution, liabilities of Summit Holdings (with certain exceptions) exceed the fair value of its assets. 
Subsidiaries of Summit Holdings are generally subject to similar legal limitations on their ability to make distributions to 
Summit Holdings.

Ownership of Our Class A Common Stock Risks

The market price of shares of our Class A common stock has fluctuated significantly, which could cause the value of your 
investment to decline.

The market price of our Class A common stock has fluctuated significantly in the past and could be subject to wide 

fluctuations in the future. Securities markets worldwide experience significant price and volume fluctuations. This market 
volatility, as well as general economic, market or political conditions, could reduce the market price of shares of our Class A 
common stock regardless of our operating performance. You may be unable to resell your shares of Class A common stock for 
a profit. In the past, following periods of volatility in the overall market and the market price of a company's securities, 
securities class action litigation has often been instituted against these companies. Such litigation, if instituted against us, could 
result in substantial costs and a diversion of our management's attention and resources. We have no current plans to pay any 
cash dividends. In addition, our operating results could be below the expectations of public market analysts and investors due 
to a number of potential factors, including variations in our quarterly operating results, additions or departures of key 
management personnel, failure to meet analysts’ earnings estimates, publication of research reports about our industry, 
litigation and government investigations, changes or proposed changes in laws or regulations or differing interpretations or 
enforcement thereof affecting our business, adverse market reaction to any indebtedness we may incur or securities we may 
issue in the future, changes in market valuations of similar companies or speculation in the press or investment community, 
announcements by our competitors of significant contracts, acquisitions, dispositions, strategic partnerships, joint ventures or 
capital commitments, adverse publicity about the industries we participate in or individual scandals, and in response the 
market price of shares of our Class A common stock could decrease significantly. 

Future issuance of additional Class A common stock, or securities convertible or exchangeable for Class A common stock, 
may adversely affect the market price of the shares of our Class A common stock.

29

 
 
 
 
 
 
 
 
Our amended and restated certificate of incorporation authorizes us to issue shares of Class A common stock and 

options, rights, warrants and appreciation rights relating to Class A common stock for the consideration and on the terms and 
conditions established by our board of directors in its sole discretion. We may need to raise significant additional equity capital 
in connection with acquisitions or otherwise. Similarly, the limited partnership agreement of Summit Holdings permits 
Summit Holdings to issue an unlimited number of additional limited partnership interests of Summit Holdings with 
designations, preferences, rights, powers and duties that are different from, and may be senior to, those applicable to the LP 
Units, and which may be exchangeable for shares of our Class A common stock. Sales of substantial amounts of Class A 
common stock, or securities convertible or exchangeable for Class A common stock, or the perception that such sales could 
occur may adversely affect the prevailing market price for the shares of our Class A common stock. Thus holders of our Class 
A common stock will bear the risk of our future issuances reducing the market price of our Class A common stock and diluting 
the value of their stock holdings in us.

Cementos Argos has significant influence over us and its interests may conflict with ours or yours in the future.

 Cementos Argos owns, in the aggregate, approximately 31% of our outstanding Class A common stock. As a result, 
Cementos Argos will have significant influence over us, the degree of which will depend on, among other things, its level of 
ownership of our Class A common stock and its ability to exercise certain rights under the terms of the Stockholders 
Agreement that we have entered into with Cementos Argos in connection with the Transaction.

Under the Stockholders Agreement, for so long as Cementos Argos continues to beneficially own at greater than 

25.0% of the then-outstanding shares of Class A common stock, neither Summit nor any of its subsidiaries may take any of the 
following actions without the prior written consent of Cementos Argos, which such approval shall not to be unreasonably 
withheld, conditioned or delayed: (i) voluntarily incur “Indebtedness” (as defined in the Credit Agreement) if immediately 
following such incurrence, either Summit’s (1) Consolidated First Lien Net Leverage Ratio (as defined in the Credit 
Agreement), or any substantially equivalent term in the Credit Agreement, would exceed 6.00:1.00 or (2) Consolidated Total 
Net Leverage Ratio (as defined in the Credit Agreement), or any substantially equivalent term in the Credit Agreement, would 
exceed 8.00:1.00, (ii) enter into any material agreements or arrangements with affiliates of Summit or its subsidiaries 
providing for payments to such affiliates in excess of $20.0 million, subject to certain exceptions, (iii) fundamentally change 
the business of Summit and its subsidiaries, taken as a whole, in a manner that would constitute a significant departure from 
the construction materials industry or result in Summit and its subsidiaries, taken as a whole, ceasing to operate in the 
construction materials industry, (iv) voluntarily liquidate, dissolve or wind-up the business and affairs of the Company; or (v) 
authorize, agree or commit to do any of the foregoing.

Accordingly, Cementos Argos’s influence over us could have a negative impact on our business and business 

prospects and negatively impact the trading price of our Class A common stock.

Sales of substantial amounts of Class A common stock in the open market by Cementos Argos and its affiliates could 
depress Summit’s Class A common stock price.

Shares of Class A common stock held by Cementos Argos will become freely tradable, following the termination of 

the lock-up agreement we have entered into with Cementos Argos in connection with the Transaction Termination Date of 
January 11, 2026, once registered pursuant to the registration rights agreement entered into with Cementos Argos in 
connection with the Transaction (the "Registration Right Agreement") or sold in compliance with Rule 144 promulgated under 
the Securities Act of 1933, as amended (the “Securities Act”). Once registered, such Class A common stock will not be subject 
to any restrictions or require further registration under the Securities Act.

Cementos Argos may wish to dispose of some or all of their interests in Summit, and as a result may seek to sell their 

shares of Class A common stock. These sales (or the perception that these sales may occur), coupled with the increase in the 
number of outstanding shares of Class A common stock, may affect the market for, and the market price of, the Class A 
common stock in an adverse manner.

Anti-takeover provisions in our organizational documents and Delaware law might discourage or delay acquisition 
attempts for us that you might consider favorable.

Our amended and restated certificate of incorporation and amended and restated bylaws contain provisions that may 

make the merger or acquisition of our company more difficult without the approval of our board of directors. Among other 
things, these provisions: would allow us to authorize the issuance of undesignated preferred stock in connection with a 
stockholder rights plan or otherwise, the terms of which may be established and the shares of which may be issued without 
stockholder approval, and which may include super voting, special approval, dividend, or other rights or preferences superior 
to the rights of the holders of Class A common stock; prohibit stockholder action by written consent unless such action is 
recommended by all directors then in office; provide that the board of directors is expressly authorized to make, alter, or repeal 

30

 
 
 
our bylaws and that our stockholders may only amend our bylaws with the affirmative vote of a majority in voting power of all 
the then-outstanding shares of stock of the Corporation entitled to vote thereon; and establish advance notice requirements for 
nominations for elections to our board or for proposing matters that can be acted upon by stockholders at stockholder 
meetings.

Further, as a Delaware corporation, we are also subject to provisions of Delaware law, which may impede or 
discourage a takeover attempt that our stockholders may find beneficial. These anti-takeover provisions and other provisions 
under Delaware law could discourage, delay or prevent a transaction involving a change in control of our company, including 
actions that our stockholders may deem advantageous, or negatively affect the trading price of our Class A common stock. 
These provisions could also discourage proxy contests and make it more difficult for you and other stockholders to elect 
directors of your choosing and to cause us to take other corporate actions you desire.

ITEM  1C. 

CYBERSECURITY  

Risk Management and Strategy

As part of our enterprise risk management function, we have implemented processes to assess, identify and manage the 
material risks facing the company, including from cyber threats. Our enterprise risk management function represents our overall 
risk management system. Our cybersecurity program is built upon recognized security frameworks. We believe that our 
processes provide us with a comprehensive assessment of potential cyber threats. We conduct regular scans, penetration tests, 
and vulnerability assessments to identify any potential threats or vulnerabilities in our systems. Our processes to assess, identify 
and manage the material risks from cyber threats include the risks arising from threats associated with third party service 
providers, including cloud-based platforms.

We have developed a cyber incident response plan which provides a documented framework for handling security 
incidents and facilitates coordination across multiple parts of the company. Dedicated members of our information security 
team, led by our Vice President, Infrastructure, constantly monitor threat intelligence feeds, handles vulnerability management 
and responds to incidents. In addition, we periodically perform simulations and drills at both a technical and management level.

Internally, we have a security awareness training platform which includes training that reinforces our information 

technology and security policies, standards and practices, and we require that our employees comply with these policies. The 
security awareness training platform offers training on how to identify potential cybersecurity risks and protect our resources 
and information. This training is mandatory for all employees on a periodic basis, and it is supplemented by testing initiatives, 
including periodic phishing tests.

From time to time, we engage third-party service providers to enhance our risk mitigation efforts. For instance, we 

have engaged an independent cybersecurity advisor to lead a cybersecurity crisis simulation exercise that has been used by our 
senior leaders to prepare for a possible cyber crisis. We have also partnered with an industry expert’s incident response group to 
help deconstruct, manage and mitigate impact from any cyber-related incident. We also purchase insurance to help protect us 
against the risk of cybersecurity breaches.

To date, we have not had a significant cybersecurity breach or attack that has had a material impact on our business or 

results of operations, and we currently do not expect that the risks from cybersecurity threats are reasonably likely to materially 
affect us, including our business strategy, results of operations or financial condition. However, as discussed more fully under 
“Item 1A. Risk Factors–Risks Related to Our Industry and Our Business–Other Risks–We are dependent on information 
technology. Our systems and infrastructure face certain risks, including cyber security risks and data leakage risks,” cyber-
attacks are continually evolving to become more sophisticated and, while we have invested in the protection of our data and 
information technology to reduce the risk of a cyber-attack, there can be no assurance that our efforts will be effective in 
preventing breakdowns or breaches in our systems.

Governance

Role of the Board

Our Board of Directors exercises direct oversight of our strategic risks through its oversight of our enterprise risk 

management function. The Audit Committee of the Board of Directors in particular is responsible for reviewing our IT security 
controls and the adequacy of our IT security program, compliance and controls with management. As part of such oversight, the 
Board of Directors, including members of the Audit Committee, receives periodic reports from our Chief Information Officer 
and Vice President, Infrastructure to assess the primary cybersecurity risks we face. Our Chief Accounting Officer reports 
directly to the Board of Directors on our company-wide enterprise risk management, which includes an evaluation of cyber 
risks and threats. 

Role of management

Our Chief Information Officer, together with our Vice President, Infrastructure, is responsible for the day-to-day 

management of our cybersecurity risks.

32

 
 
We have a security incident response plan in place. We use this incident response plan as part of the process we 

employ to keep our management and Board of Directors informed about and monitor the prevention, detection, mitigation, and 
remediation of cybersecurity incidents. The incident response plan is a set of coordinated procedures and tasks that our incident 
response team executes with the goal of ensuring timely and accurate resolution of cybersecurity incidents.

Our Chief Information Officer and our VP, Infrastructure have extensive experience in the information technology 

area, including cybersecurity. In particular, our Chief Information Officer has over 10 years of professional experience in the 
information security area, including as a result of his service as an IT VP at companies such as Prologis, and holds certifications 
relating to cybersecurity. Further, our VP, Infrastructure has over 15 years of professional experience in the information 
security area, including as a result of roles of increasing responsibility at Summit Materials and his service as a senior systems 
engineer at various companies.

ITEM 2.  

PROPERTIES. 

Properties

Our headquarters are located in a 33,191 square foot office space, which we lease in Denver, Colorado, under a lease 

expiring on November 30, 2033.

We mine a variety of hard rock materials including limestone, granite, quartzite and unconsolidated materials 

including clay, sand and gravel at our quarry operations. The aggregates produced at our quarries are utilized as general 
construction aggregates, bituminous asphalt pavement and ready-mix concrete. Our reserves and resources are across over 230 
sites, to which we have adequate road, barge or railroad access.  

A map showing the location of all mining properties is below:

We periodically perform sub-surface exploration at most of our sites through drilling methods. At most of our sites, 
our mining operations are conducted using surface open pit techniques. Mineral resources are defined as having a reasonable 
prospect of extraction, and is likely to, either in whole or in part, to become economically extractable. Mineral resource 
estimates were obtained using property boundaries, exploration coverage and regional geologic research. Areas of 
uneconomically thick overburden or poor aggregate quality rock were defined to the best ability and excluded from reserves or 
resources areas. Mineral reserves are defined as an estimate of tonnage that can be economically extracted and includes an 
allowance for losses that may occur when the material is mined or extracted. Mineral reserves estimates were made using 

33

 
 
 
 
similar parameters as for mineral resources. Quantities are counted as reserves based on the nature of the permit, property 
boundaries, mineral rights and sub-surface exploration. Areas that are not yet permitted or not explored through a drilling 
campaign are typically excluded from reserves. Due to the nature of our products, we do not perform metallurgical testing, 
however during exploration, material is tested for construction aggregates and materials or cement suitability.

As of December 30, 2023, we had 3.9 billion tons of proven and probable mineral reserves and 1.4 billion tons of 

measured and indicated mineral resources. All mineral reserves are reported as saleable tons. All mineral resources are reported 
as in-situ tons. In total, we owned 44 percent and leased 56 percent of total mineral reserves and resources. We do not consider 
any of our individual quarrying operations as material for disclosure purposes. We estimate that the useful life of our reserves 
serving our aggregates and cement businesses are approximately 55 years and 170 years, respectively, based on the average 
production rates in 2023 and 2022. We obtained technical reports covering each of our mining sites prepared by Continental 
Placer Inc. as of December 30, 2023. The technical reports were prepared in accordance with the requirements of the 
Modernization of Property Disclosures for Mining Registrants set forth in subpart 1300 of Regulation S-K (the “SEC Mining 
Modernization Rules”). Inferred resources are defined as a mineral resource for which quantity and grade have been estimated 
but not yet verified. The terms defined in the table below are defined and used in accordance with the SEC Mining 
Modernization Rules. By segment, our estimate of proven and probable mineral reserves and measured and indicated mineral 
resources as of December 30, 2023 are shown in the table below:

The analysis of our reserves and resources has been developed by our personnel in collaboration with Continental 

Placer Inc. (“CPI”), designated as our “qualified person.” Our management teams periodically review our reserves by 
performing sub-surface exploration as part of our mine planning process. Further, we also review and update our mineral 
resources and reserves as operations progress through our reserves, and as mining permits are submitted for updates and 
approvals. The modeling and analysis of the Company’s reserves and resources has been developed by Company mine 
personnel and reviewed by several levels of internal management, including CPI. The development of such reserves and 
resources estimates, including related assumptions, was a collaborative effort between CPI and Company staff. This section 
summarizes the internal control considerations for the Company’s development of estimations, including assumptions, used in 
reserve and resource analysis and modeling.

When determining reserves and resources, as well as the differences between reserves and resources, management 

developed specific criteria, each of which must be met to qualify as a reserve or resource, respectively. These criteria, such as 
demonstration of economic viability, legal right to mine, and material quality are specific and attainable. CPI and Company 
management agree on the reasonableness of the criteria for the purposes of estimating reserves and resources. Calculations 
using these criteria are either performed or reviewed and validated by CPI.

Estimations and assumptions were developed independently for each geographical operational area. All estimates 

require a combination of historical data and key assumptions and parameters. When possible, resources and data from generally 
accepted industry sources, such as governmental resource agencies, were used to develop these estimations.

PART II 

ITEM  5.  

MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS 
AND ISSUER PURCHASES OF EQUITY SECURITIES.

Market Information

Summit Inc.’s Class A common stock began publicly trading on the NYSE under the symbol “SUM” on March 11, 

2015. Prior to that time, there was no public market for our Class A common stock. Our Class B common stock is not publicly 
traded. As of February 12, 2024, there were seven holders of record of our Class A common stock, 30 holders of record of our 
Class B common stock and one holder of record of our preferred stock. 

These stockholder figures do not include a substantially greater number of holders whose shares are held of record by 

banks, brokers and other financial institutions. 

All of the outstanding limited liability company interests of Summit LLC are held by Summit Materials Intermediate 

Holdings, LLC, an indirect subsidiary of Summit Inc. There is no established public trading market for limited liability 
company interests of Summit LLC.

Dividends

Summit Holdings makes cash distributions to Summit Holdings’ LP Unit holders to cover tax obligations arising from 
allocated taxable income. As an LP Unit holder, Summit Inc. received cash distributions from Summit Holdings in excess of the 
amount required to satisfy Summit Inc.’s tax obligations. In fiscal 2022, Summit Inc. primarily used the excess cash of 
approximately $59.3 million to acquire newly-issued LP Units from Summit Holdings. The LP Units were purchased at a per 
unit price of $29.94, which is the volume weighted average price per share of the Class A common stock for the five trading 
days ended December 2, 2022. Immaterial cash payments were made in lieu of fractional shares.

If Summit Inc. uses future excess tax distributions to purchase additional LP Units, in order to maintain the 
relationship between the shares of Class A common stock and the LP Units, our board of directors may continue to declare 
stock dividends on the Class A common stock.

Summit Inc. has no current plans to pay cash dividends on its Class A common stock. The declaration, amount and 

payment of any future dividends on shares of Class A common stock is at the sole discretion of our board of directors and we 
may reduce or discontinue entirely the payment of any such dividends at any time. Our board of directors may take into account 
general and economic conditions, our financial condition and operating results, our available cash and current and anticipated 
cash needs, capital requirements, contractual, legal, tax and regulatory restrictions and implications on the payment of dividends 
by us to our stockholders or by our subsidiaries to us, and such other factors as our board of directors may deem relevant.

Summit Inc. is a holding company and has no material assets other than its ownership of LP Units. Should we decide 

to pay a cash dividend on our Class A common stock in the future, we anticipate funding this cash dividend by causing Summit 
Holdings to make distributions to Summit Inc. in an amount sufficient to cover such dividend, whereupon the other holders of 
LP Units will also be entitled to receive distributions pro rata in accordance with the percentages of their respective limited 
partnership interests. Because Summit Inc. must pay taxes and make payments under the TRA, any amounts ultimately 
distributed as dividends to holders of our Class A common stock are expected to be less on a per share basis than the amounts 
distributed by Summit Holdings to its partners on a per LP Unit basis.

The agreements governing our senior secured credit facilities and the Senior Notes contain a number of covenants that 
restrict, subject to certain exceptions, Summit LLC’s ability to pay distributions to its parent company and ultimately to Summit 
Inc. See Note 8, Debt, to our consolidated financial statements.

Any financing arrangements that we enter into in the future may include restrictive covenants that limit our ability to 

pay dividends. In addition, Summit Holdings is generally prohibited under Delaware law from making a distribution to a 
limited partner to the extent that, at the time of the distribution, after giving effect to the distribution, liabilities of Summit 
Holdings (with certain exceptions) exceed the fair value of its assets.

Subsidiaries of Summit Holdings are generally subject to similar legal limitations on their ability to make distributions 

to Summit Holdings.

Issuer Purchases of Equity Securities

In March 2022, our Board of Directors authorized a share repurchase program, whereby we can repurchase up to 

$250.0 million of our Class A common stock. As of December 30, 2023, approximately $149.0 million remained available for 
share repurchases under the share repurchase program. The repurchase program does not obligate the Company to acquire any 
specific dollar amount of Class A common stock and may be suspended or discontinued at any time.

During the quarter ended December 30, 2023, we did not purchase any of our equity securities that are registered under 

Section 12(b) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

Unregistered Sales of Equity Securities

There were no unregistered sales of equity securities which have not been previously disclosed in a quarterly report on 

Form 10-Q or a current report on Form 8-K during the year ended December 30, 2023.

Overview

Summit’s vision is to be the most socially responsible, integrated construction materials solution provider, 
collaborating with stakeholders to deliver differentiated innovations and solve our customers’ challenges. Within our markets, 
we strive to be a market leader by offering customers a single-source provider for construction materials and related vertically 
integrated downstream products. Our materials include aggregates, which we supply across the United States, and in British 
Columbia, Canada, and cement, which we supply to surrounding states along the Mississippi River from Minnesota to 
Louisiana. In addition to supplying aggregates to customers, we use a portion of our materials internally to produce ready-mix 
concrete and asphalt paving mix, which may be sold externally or used in our paving and related services businesses. Our 
vertically integrated business model creates opportunities to increase aggregates volumes, optimize margin at each stage of 
production and provide customers with efficiency gains, convenience and reliability, which we believe gives us a competitive 
advantage.

We are organized into nine reporting units that make up our three distinct operating segments—West, East and 

Cement. As of December 30, 2023, we operate in 21 U.S. states and in British Columbia, Canada and currently have assets in 
21 U.S. states and British Columbia, Canada. The map below illustrates our geographic footprint:

Business Trends and Conditions

The U.S. construction materials industry is composed of four primary sectors: aggregates; cement; ready-mix concrete; 

and asphalt paving mix. Each of these materials is widely used in most forms of construction activity. Participants in these 
sectors typically range from small, privately-held companies focused on a single material, product or market to publicly traded 
multinational corporations that offer a wide array of construction materials and services. Competition is constrained in part by 
the distance materials can be transported efficiently, resulting in predominantly local or regional operations. Due to the lack of 
product differentiation, competition for all of our products is predominantly based on price and, to a lesser extent, quality of 
products and service. Accordingly, our profitability is generally dependent on the level of demand for our materials and 
products and our ability to control operating costs.

Our revenue is derived from multiple end-use markets including public infrastructure construction and private 

residential and nonresidential construction. Public infrastructure includes spending by federal, state, provincial and local 
governments for roads, highways, bridges, airports and other infrastructure projects. Public infrastructure projects have 
historically been a relatively stable portion of state and federal budgets. Residential and nonresidential construction consists of 
new construction and repair and remodel markets. Any economic stagnation or decline, which could vary by local region and 
market, could affect our results of operations. Our sales and earnings are sensitive to national, regional and local economic 
conditions and particularly to cyclical changes in construction spending, especially in the private sector. From a macroeconomic 
view, we see a positive trend in highway obligations, but headwinds in housing starts. 

Transportation infrastructure projects, driven by both federal and state funding programs, represent a significant share 
of the U.S. construction materials market. Federal funds are allocated to the states, which are required to match a portion of the 

40

 
 
 
 
 
federal funds they receive. Federal highway spending uses funds predominantly from the Federal Highway Trust Fund, which 
derives its revenue from taxes on diesel fuel, gasoline and other user fees. The dependability of federal funding allows the state 
departments of transportation to plan for their long term highway construction and maintenance needs. The Infrastructure 
Investment and Jobs Act (IIJA) was signed into law on November 15, 2021. The IIJA provides $1.2 trillion in funding over five 
years from 2022 through 2026, which includes $347.8 billion for highways, and $91.2 billion for transit.

In addition to federal funding, state, county and local agencies provide highway construction and maintenance funding. 

Our four largest states by revenue, Texas, Utah, Missouri and Kansas, represented approximately 26%, 14%, 10% and 8%, 
respectively, of our total revenue in 2023. The following is a summary of key funding initiatives in those states:

•

•

•

•

The Texas Department of Transportation (“TXDOT”) fiscal year 2024-2025 biennial state budget bill was signed by 
the Governor of Texas on June 18, 2023. The TXDOT budget for fiscal year 2024 totals $18.54 billion, a 24% increase 
over fiscal year 2023 of $14.96 billion. Since the biennial budget for fiscal year 2023 was determined in 2021, prior to 
passage of the IIJA, the new bill is the first biennial state budget to incorporate increased federal funding under the 
IIJA.

Total original transportation appropriation for the state of Utah in fiscal year 2024 is approximately $3.02 billion, 12% 
increase over fiscal year 2023 original transportation appropriations.

Kansas Legislative Research Department report which details the legislatively approved budget for the Kansas 
Department of Transportation totals $2.16 billion for fiscal year 2024, a 5% increase over fiscal year 2023.

The state budget for the Missouri Department of Transportation grew by 17% between fiscal year 2023 and fiscal year 
2024, from $3.51 billion to $4.11 billion.

Use and consumption of our products fluctuate due to seasonality. Nearly all of the products used by us, and by our 

customers, in the private construction and public infrastructure industries are used outdoors. Our highway operations and 
production and distribution facilities are also located outdoors. Therefore, seasonal changes and other weather-related 
conditions, in particular extended rainy and cold weather in the spring and fall and major weather events, such as hurricanes, 
tornadoes, tropical storms, heavy snows and flooding, can adversely affect our business and operations through a decline in 
both the use of our products and demand for our services. In addition, construction materials production and shipment levels 
follow activity in the construction industry, which typically occurs in the spring, summer and fall. Warmer and drier weather 
during the second and third quarters of our fiscal year typically result in higher activity and revenue levels during those 
quarters. The first quarter of our fiscal year typically has lower levels of activity due to weather conditions.

We are subject to commodity price risk with respect to price changes in liquid asphalt and energy, including fossil 

fuels and electricity for aggregates, cement, ready-mix concrete and asphalt paving mix production and diesel fuel for 
distribution vehicles and production related mobile equipment. Liquid asphalt escalator provisions in most of our private and 
commercial contracts limit our exposure to price fluctuations in this commodity. We often obtain similar escalators on public 
infrastructure contracts. In addition, as we seek to manage our risk to increasing energy prices, we enter into various firm 
purchase commitments, with terms generally less than one year, for certain raw materials.

Combination with Argos North America Corp.

In January 2024, Summit completed a merger with Argos North America Corporation ("Argos USA"), Cementos 

Argos S.A., Argos SEM LLC and Valle Cement Investments, Inc., pursuant to which Summit acquired all of the outstanding 
equity interests (the "Transaction") of Argos USA from the Argos SEM LLC and Valle Cement Investments, Inc. in exchange 
for $1.2 billion of cash, the issuance of 54,720,000 shares of our Class A common stock and one preferred share in a transaction 
valued at approximately $3.2 billion. The purchase price is subject to customary adjustments, with any upward or downward 
adjustments made against the cash consideration. The Transaction Agreement contains customary representations and 
warranties, covenants and agreements, including entry into a stockholder agreement. The cash consideration was funded from 
the net proceeds of an $800 million offering of Senior Notes due 2031 and new term loan borrowings under our current credit 
facility.

The Argos USA assets include four integrated cement plants, two grinding facilities, 140 ready-mix concrete plants, 

eight ports and 10 inland terminals across the East and Gulf Coast regions, with a total installed cement grinding capacity of 9.6 
million tons per annum and a total import capacity of 5.4 million tons of cement per annum. The import facilities allow the 
importing of cement from other countries, including a minimum quantity from a cement plant in Cartagena, Colombia, owned 
by Cementos Argos S.A., as stipulated under a cement supply agreement entered into upon closing the Transaction. The Argos 
USA assets included 1.2 billion tons of reserves and resources in four quarries.

41

 
 
 
For the year ended December 31, 2023, Argos USA sold approximately 6.7 million tons of cement and 5.2 million 

yards of ready-mix concrete, recognizing approximately $1.7 billion of revenue.

Financial Highlights— Year ended December 30, 2023 

The principal factors in evaluating our financial condition and operating results for the year ended December 30, 2023 

are:

•

•

•

•

•

•

•

•

Net revenue increased 9.9% or $220.7 million in 2023 as compared to 2022, primarily resulting from increases in 
average sales prices and our acquisition program, which more than offset reduced volumes due to divestitures 
completed in 2022.
Our operating income increased 15.5% or $41.6 million in 2023 as compared to 2022, as our increases in revenue 
exceeded inflationary impacts on our cost of revenue. We incurred $25.6 million of transaction and integration costs 
related to our agreement to combine with Argos USA, which reduced our operating income. 
Average sales price increased 14.6%, 13.2%, 11.2% and 15.6% in aggregates, cement, ready-mix concrete and asphalt, 
respectively. 
Sales volume decreased 1.9%, 6.8% and 2.7% in aggregates, cement and ready-mix concrete, respectively, and asphalt 
volumes remained flat.
In December 2023, we issued $800.0 million of 7.250% senior notes due 2031 (the “2031 Notes”). The proceeds from 
the 2031 Notes were used, together with term loan borrowings, to finance the Argos USA acquisition. 
In 2023, we closed on three acquisitions in the West segment, including one in the Phoenix, Arizona market, and one in 
the East segment, for a total of $239.5 million using existing cash balances.
In 2023, we divested two businesses in the West segment, resulting in cash proceeds of $65.6 million and a total gain 
on disposition of $15.0 million.
In the second half of 2023, we paid $132.4 million to reacquire certain TRA interests, and recorded a tax receivable 
agreement benefit of $162.2 million as the cash paid to acquire the interests was less than the carrying value of the 
TRA liability, inclusive of annual adjustments to the TRA liability.

Components of Operating Results

Total Revenue

We derive our revenue predominantly by selling construction materials and products and providing paving and related 
services. Construction materials consist of aggregates and cement. Products consist of related downstream products, including 
ready-mix concrete, asphalt paving mix and concrete products. Paving and related services that we provide are primarily asphalt 
paving services.

Revenue derived from the sale of construction materials is recognized when control transfers to unaffiliated customers. 

Typically this occurs when products are shipped. Product revenue generally includes sales of aggregates, cement and related 
downstream products and other materials to customers, net of discounts or allowances and taxes, if any.

Revenue derived from paving and related services is recognized using a method similar to the percentage-of-
completion method, measured by the cost incurred to date compared to estimated total cost of each project. This method is used 
because management considers cost incurred to be the best available measure of progress on these contracts. Due to the inherent 
uncertainties in estimating costs, it is at least reasonably possible that the estimates used will change over the life of the 
contract.

Operating Costs and Expenses

The key components of our operating costs and expenses consist of the following:

Cost of Revenue (excluding items shown separately) 

Cost of revenue consists of all direct production and delivery costs and primarily includes labor, repair and 
maintenance, utilities, raw materials, fuel, transportation, subcontractor costs, and royalties. Our cost of revenue is directly 
affected by fluctuations in commodity energy prices, primarily diesel fuel, liquid asphalt and other petroleum-based resources. 
As a result, our adjusted cash gross profit margins can be significantly affected by changes in the underlying cost of certain raw 
materials if they are not recovered through corresponding changes in revenue. We attempt to limit our exposure to changes in 
commodity energy prices by entering into forward purchase commitments when appropriate. In addition, we have sales price 
adjustment provisions that provide for adjustments based on fluctuations outside a limited range in certain energy-related 

42

 
 
 
 
 
 
 
 
 
 
production costs. These provisions are in place for most of our public infrastructure contracts, and we seek to include similar 
price adjustment provisions in our private contracts.

General and Administrative Expenses

General and administrative expenses consist primarily of salaries and personnel costs, including stock-based 
compensation charges, for our sales and marketing, administration, finance and accounting, legal, information systems, human 
resources and certain managerial employees. Additional expenses include audit, consulting and professional fees, travel, 
insurance, rental costs, property taxes and other corporate and overhead expenses.

Transaction and Integration Expenses

Transaction and integration expenses typically include finders fees, legal, accounting and other professional costs. 

Integration expenses represent costs incurred to combine the company and its acquired businesses. Integration expenses 
typically include strategic consulting services, facility consolidations, one time employee related costs such as retention and 
severance costs, costs of integrating information system infrastructure, enterprise planning systems, processes, and other non-
recurring integration related costs. Costs incurred related to the revision or issuance of new debt to finance the transactions are 
recorded as deferred financing costs. Transaction and integration costs are combined and presented on one line item in the 
consolidated statements of operations.

Depreciation, Depletion, Amortization and Accretion

Our business is capital intensive. We carry property, plant and equipment on our balance sheet at cost, net of 
applicable depreciation, depletion and amortization. Depreciation on property, plant and equipment is computed on a straight-
line basis or based on the economic usage over the estimated useful life of the asset. The general range of depreciable lives by 
category, excluding mineral reserves, which are depleted based on the units of production method on a site-by-site basis, is as 
follows:

Buildings and improvements
Plant, machinery and equipment
Office equipment
Truck and auto fleet
Mobile equipment and barges
Landfill airspace and improvements
Other

10 - 30 years
7 - 20 years
3 - 7 years
5 - 8 years
6 - 8 years
10 - 30 years
4 - 20 years

Amortization expense is the periodic expense related to leasehold improvements and intangible assets. The intangible 
assets were recognized with certain acquisitions and are generally amortized on a straight-line basis over the estimated useful 
lives of the assets. Leasehold improvements are amortized over the lesser of the life of the underlying asset or the remaining 
lease term.

Accretion expense is the periodic expense recorded for the accrued mining reclamation liabilities and landfill closure 

and post-closure liabilities using the effective interest method.

Results of Operations

The following discussion of our results of operations is focused on the key financial measures we use to evaluate the 
performance of our business from both a consolidated and operating segment perspective. Operating income and margins are 
discussed in terms of changes in volume, pricing and mix of revenue source (i.e., type of product sales or service revenue). We 
focus on operating margin, which we define as operating income as a percentage of net revenue, as a key metric when assessing 
the performance of the business, as analyzing changes in costs in relation to changes in revenue provides more meaningful 
insight into the results of operations than examining costs in isolation.

Operating income (loss) reflects our profit from operations after taking into consideration cost of revenue, general and 
administrative expenses, depreciation, depletion, amortization and accretion and gain on sale of property, plant and equipment. 
Cost of revenue generally increases ratably with revenue, as labor, transportation costs and subcontractor costs are recorded in 

43

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
cost of revenue. General and administrative expenses as a percentage of revenue vary throughout the year due to the seasonality 
of our business, and may also be impacted by acquisition and divestiture activities, depending on the size of the business 
acquired or divested. During 2023, our general and administrative expenses were not materially impacted by our acquisition or 
divestiture activity.

The table below includes revenue and operating income by segment for the periods indicated. Operating income (loss) 

by segment is computed as earnings before interest, loss on debt financings, tax receivable agreement expense, gain on sale of 
business, other income / expense and taxes.

Adjusted EBITDA and Adjusted EBITDA Margin are non-GAAP measures that we find helpful in monitoring the 
performance of our business. See “Non-GAAP Performance Measures” below for the definitions of Adjusted EBITDA 
and Adjusted EBITDA Margin and for a reconciliation of Adjusted EBITDA to net income, which is the most directly 
comparable GAAP measure.

Net revenue increased $220.7 million in the year ended December 30, 2023, primarily resulting from increases in our 

average sales prices and our acquisition program, which more than offset a $73.5 million decrease in net revenues due to 
divestitures. Of the increase in net revenue, $102.8 million was from increased sales of materials, $101.3 million from increased 
sales of products and $16.5 million from increased service revenue. We generated organic volume growth of 10.1% in asphalt, 
offset by a decrease of 3.1%, 6.8% and 12.2% in aggregates, cement and ready-mix concrete, respectively, during 2023 over the 
prior year period. We had organic price growth in our aggregates, cement, ready-mix and asphalt lines of business of 14.2%, 
13.2%, 10.7% and 13.9%, respectively, during 2023.

Operating income increased by $41.6 million in 2023 as compared to 2022, as increases in revenue exceeded 

inflationary impacts on our cost of revenue and more than offset higher general and administrative expenses resulting from 
adjustments to estimates of health care and short term incentive amounts and $25.6 million of transaction and integration costs 
related to our combination with Argos USA.

For the year ended December 30, 2023, our operating margin percentage increased to 12.7% from 12.1% and adjusted 

EBITDA margin, as defined below, increased to 23.7% from 22.1% in 2023 as compared to 2022, due to the factors noted 
above.

As a vertically-integrated company, we include intercompany sales from materials to products and from products to 

services when assessing the operating results of our business. We refer to revenue inclusive of intercompany sales as gross 
revenue. These intercompany transactions are eliminated in the consolidated financial statements. Gross revenue by product

Volumes are shown in tons for aggregates, cement and asphalt and in cubic yards for ready-mix concrete.
Pricing is shown on a per ton basis for aggregates, cement and asphalt and on a per cubic yard basis for ready-mix 
concrete.

Revenue from aggregates increased $89.0 million in the year ended December 30, 2023. Aggregate average sales 

prices of $13.83 per ton increased 14.6% in 2023 as compared to 2022, primarily due to pricing actions designed to more than 
offset recent inflationary conditions. We continue to focus on pricing to what local market conditions will allow. Organic 
aggregate volumes decreased 3.1% in 2023 as compared to 2022, primarily due to residential demand conditions, as well as 
unfavorable weather in certain geographies as noted below.

Revenue from cement increased $18.9 million in the year ended December 30, 2023. In 2023, organic cement volumes 

decreased 6.8% and organic cement average sales prices increased 13.2%, as compared to 2022.

Revenue from ready-mix concrete increased $56.9 million in the year ended December 30, 2023. In 2023, our ready-

mix volumes decreased 2.7% and our average sales prices increased 11.2%. The volume decrease in 2023 occurred primarily in 
our South Texas market due to moderating demand in our residential markets, while our price increases occurred across all of 
our major markets.

Revenue from asphalt increased $37.9 million in the year ended December 30, 2023, primarily due to price increases. 
In 2023, organic pricing increased 13.9% and while volumes remained flat, organic volumes increased by 10.1%, with pricing 
and volume gains in our North Texas and Intermountain West geographies, as compared to 2022.

Other Financial Information

Transaction and Integration Costs

Our transaction and integration costs were $26.8 million and $3.4 million for the years ended December 30, 2023 and 
December 31, 2022, respectively. In 2023, $25.6 million of the transaction costs were related to our acquisition and integration 
costs associated with the agreement to combine with Argos USA, which closed in January 2024.

Interest expense

Our interest expense was $114.2 million and $87.0 million for the years ended December 30, 2023 and December 31, 

2022, respectively, as rising interest rates led to higher interest expense in 2023. Additionally, in December 2023, we issued 
$800.0 million of 7.250% senior notes due in January 2031. 

Loss on Debt Financings

In December 2022, we amended and extended our $509.6 million term loan. In connection with this transaction, 

charges of $1.7 million were recognized for the quarter ended December 31, 2022. The fees included $0.8 million of 
arrangement and third party fees, $0.4 million for the write-off of unamortized original issue discount and $0.5 million for the 
write-off of unamortized deferred financing fees.

In September 2021, we redeemed all $300.0 million 5.125% Senior Notes due 2025 using existing cash on hand. In 

connection with this transaction, charges of $6.0 million were recognized in the quarter ended October 2, 2021. The fees 
included $3.9 million for the applicable prepayment premium and $2.1 million for the write-off of unamortized deferred 
financing fees.

We continue to make progress on our strategy to divest certain businesses through portfolio optimization. In 2023, we 
sold two businesses in the West segment, resulting in cash proceeds of $65.6 million and a net gain on disposition of businesses 
of $15.0 million. In 2022, we sold three businesses in the East segment, resulting in cash proceeds of $373.1 million and a net 
gain on disposition of businesses of $172.4 million.

Tax Receivable Agreement (Benefit) Expense

Our TRA (benefit) expense for the years ended December 30, 2023 and December 31, 2022 was $(162.2) million and 
$1.6 million, respectively. In the second half of 2023, we acquired certain interests in our TRA agreement for $132.4 million, 
and recognized a benefit of $157.5 million reflecting the difference between the carrying value of the related TRA liability and 
the cash payment made to acquire the interests. Further, each year, we update our estimate as to when TRA payments will be 
made. When payments are made under the TRA, a portion of the payment made will be characterized as imputed interest under 
Internal Revenue Service ("IRS") regulations. We also updated our estimate of the state income tax rate that will be in effect at 
the date the TRA payments are made. As a result of updated state income tax rate, and the timing of expected utilization of 
attributes noted above, we adjusted our TRA liability by approximately $4.7 million.

Income Tax Expense 

Our income tax expense for the years ended December 30, 2023 and December 31, 2022 was $104.8 million and $85.5 

million, respectively.. The effective tax rate for Summit Inc. differs from the federal statutory tax rate primarily due to (1) the 
non-taxability of the tax receivable agreement benefit (2) tax depletion expense in excess of the expense recorded under U.S. 
GAAP, (3) basis differences in assets divested, (4) state taxes, (5) the minority interest in the Summit Holdings partnership that 
is allocated outside of the Company and (6) various other items such as limitations on meals and entertainment, certain stock 
compensation and other costs.

As of December 30, 2023 and December 31, 2022, Summit Inc. had a valuation allowance of $1.1 million and $1.1 

million against our deferred tax assets, respectively.

and Adjusted EBITDA Margin and for a reconciliation of Adjusted EBITDA to net income, which is the most directly 
comparable GAAP measure.

Net revenue in the West segment increased $200.8 million in the year ended December 30, 2023, due to net revenue 

increases across all lines of business and from the impact of acquisitions of $107.7 million. Organic aggregate volumes 
decreased 8.3% in 2023 as compared to 2022, while organic aggregates average sales prices increased 16.2%, as price increases 
were implemented across all geographies to help offset inflationary factors. Organic ready-mix concrete volumes decreased 
12.9% and our organic ready-mix concrete average sales prices increased 10.8%. Higher mortgage interest rates are negatively 
impacting residential demand and, by extension limiting residential construction activity. These conditions are affecting, to 
varying degrees, our two largest markets, Houston and Salt Lake City.

The West segment’s operating income increased $36.0 million and Adjusted EBITDA increased $50.6 million in the 
year ended December 30, 2023. The increases in operating income and Adjusted EBITDA in 2023 occurred primarily due to 
increases in average sales prices for aggregates and ready-mix concrete. The operating margin percentage in the West segment 
increased slightly in 2023 as compared to 2022, due to increases in our average sales prices which exceeded our costs of 
revenue.

Revenue from aggregates in the West segment increased $38.8 million in 2023 over 2022, due to an increase in 
aggregates sales pricing and approximately $14.0 million came from acquisitions. Aggregates pricing in 2023 increased 16.7% 
when compared to 2022, as we implemented price increases in all our markets. Aggregates volumes decreased 5.0% in 2023, 
primarily due to decreases in our British Columbia and South Texas markets.

Revenue from ready-mix concrete in the West segment increased $66.8 million in 2023 over 2022, of which 
approximately $86.2 million came from acquisitions. For the year ended December 30, 2023, organic ready-mix concrete prices 
increased 10.8%, as price increases were implemented to help offset inflationary factors. For the year ended December 30, 
2023, our ready-mix concrete organic volumes decreased 12.9% due to reduced residential demand. 

Revenue from asphalt in the West segment increased $72.7 million in 2023, as asphalt volumes increased 17.4% and 

asphalt pricing increased 14.2%. The volume increase was primarily due to growth in our North Texas, Intermountain West and 
British Columbia markets. Revenue for paving and related services in the West segment increased by $90.3 million in 2023, 
primarily due to increased demand. 

Prior to eliminations of intercompany transactions, the net effect of volume and pricing changes on gross revenue for 

the year ended December 30, 2023 was approximately $20.5 million and $157.8 million, respectively.

Pricing

 (6.8) %

 13.2 %

Revenue from cement increased $18.9 million in 2023, due to increased pricing of 13.2%, which more than offset 

decreased volumes of 6.8%. The volume decrease was primarily due to a large non-recurring project from 2022, deferred 
paving projects in our northern markets due to wet weather, and an overall moderate decline in market demand.

Liquidity and Capital Resources

Our primary sources of liquidity include cash on-hand, cash provided by operations, amounts available for borrowing 
under our senior secured credit facilities and capital-raising activities in the debt and capital markets. In addition to our current 
sources of liquidity, we have access to liquidity through public offerings of shares of our Class A common stock. To facilitate 
such offerings, in January 2023, we filed a shelf registration statement with the SEC that will expire in January 2026. The 
amount of Class A common stock to be issued pursuant to this shelf registration statement was not specified when it was filed 
and there is no specific limit on the amount we may issue. The specifics of any future offerings, along with the use of the 
proceeds thereof, will be described in detail in a prospectus supplement, or other offering materials, at the time of any offering.

As of December 30, 2023, we had $374.2 million in cash and cash equivalents and $609.2 million of working capital 

as compared to $520.5 million and $762.5 million, respectively, at December 31, 2022. Working capital is calculated as current 
assets, except for restricted cash, less current liabilities. There was a restricted cash balance of $800 million related to the 2031 
Notes, noted below, as of December 30, 2023, and no restricted cash balance as of December 31, 2022.

Our remaining borrowing capacity on our $395.0 million senior secured revolving credit facility as of December 30, 

2023 was $374.1 million, which is net of $20.9 million of outstanding letters of credit, and is fully available to us within the 
terms and covenant requirements of our credit agreement. In January 2024, we amended our senior secured revolving credit 
facility, increasing the total availability to $625.0 million.

In March 2022, our Board of Directors authorized a share repurchase program, whereby we can repurchase up to 

$250.0 million of our Class A common stock. During the first nine months of 2022, we repurchased 3.4 million shares of Class 
A common stock for $101.0 million. As of December 30, 2023, approximately $149.0 million remained available for share 
repurchases under the share repurchase program.

Given the seasonality of our business, we typically experience significant fluctuations in working capital needs and 

balances throughout the year. Our working capital requirements generally increase during the first half of the year as we build 
up inventory and focus on repair and maintenance and other set-up costs for the upcoming season. Working capital levels then 

50

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
decrease as the construction season winds down and we enter the winter months, which is when we see significant inflows of 
cash from the collection of receivables.

Our acquisition strategy has at times required us to raise capital through equity issuances or debt financings. As of 

December 30, 2023 and December 31, 2022, our long-term borrowings totaled $2.3 billion and $1.5 billion, for which we 
incurred $101.8 million and $77.0 million of interest expense, respectively. Our senior secured revolving facility has been 
adequate to fund our seasonal working capital needs and certain acquisitions. We had no outstanding borrowings on the senior 
secured revolving credit facility as of December 30, 2023.

For details regarding certain other material cash requirements from known contractual and other obligations see “—

Contractual Obligations” below.

During 2023, we also received $65.6 million in proceeds from divestitures as part of our Elevate Summit strategy. 

Management will continue to optimize the portfolio, which could include future divestitures.

We believe we have access to sufficient financial resources from our liquidity sources to fund our business and 

operations, including contractual obligations, capital expenditures and debt service obligations, for at least the next twelve 
months. Our growth strategy contemplates future acquisitions for which we believe we have sufficient access to capital. We 
also plan to divest of certain dilutive businesses as we rationalize our portfolio, which will also generate additional capital.

As market conditions warrant, we may, from time to time, seek to purchase our outstanding debt securities or loans, 

including Senior Notes and borrowings under our senior secured credit facilities. Such transactions could be privately 
negotiated, open market transactions, tender offers or otherwise. Subject to any applicable limitations contained in the 
agreements governing our indebtedness, any purchases made by us may be funded by the use of cash on our balance sheet or 
the incurrence of new secured or unsecured debt. The amounts involved in any such purchase transactions, individually or in 
the aggregate, may be material. Any such purchases may equate to a substantial amount of a particular class or series of debt, 
which may reduce the trading liquidity of such class or series.

Our Long-Term Debt

Please refer to the notes to the consolidated financial statements found elsewhere in this report for detailed information 
regarding our long-term debt and senior secured revolving credit facility, scheduled maturities of long-term debt and affirmative 
and negative covenants. Among other things, we are required to maintain a Consolidated First Lien Net Leverage Ratio that is 
no greater than 4.75 to 1.00. Our first lien net leverage ratio, for purposes of this maintenance requirement, is calculated 
following each quarter based on information for the most recently ended four fiscal quarters for which internal financial 
information is available by dividing our Consolidated First Lien Net Debt as of the end of such period by our Consolidated 
EBITDA for such period. Consolidated EBITDA for purposes of our senior secured credit facility is calculated in accordance 
with our presentation of Further Adjusted EBITDA below. We define Further Adjusted EBITDA as Adjusted EBITDA plus 
transaction costs and the EBITDA contribution of certain recent acquisitions.

For the years ended December 30, 2023 and December 31, 2022, our Consolidated First Lien Net Leverage Ratio was 

0.29 to 1.00 and 0.01 to 1.00, respectively, based on consolidated first lien net debt of $167.2 million and $3.2 million as of 
December 30, 2023 and December 31, 2022, respectively, divided by Further Adjusted EBITDA of $581.6 million and 
$493.0 million for the years ended December 30, 2023 and December 31, 2022, respectively. As of December 30, 2023 and 
December 31, 2022, we were in compliance with all debt covenants.

The following table sets forth a reconciliation of net income to Adjusted EBITDA and Further Adjusted EBITDA for 

the periods indicated. Adjusted EBITDA and Further Adjusted EBITDA are not U.S. GAAP measures and should not be 
considered in isolation, or as a substitute for our results as reported under U.S. GAAP.

Represents non-cash equity-based compensation granted to employees.
The adjustment for acquisition and integration costs related to the agreement to combine with Argos USA is comprised 
of banking fees, advisory, legal and professional fees incurred relating to our agreement to combine with Argos USA.
Consists primarily of interest income earned on cash balances. Includes the net (gain) loss recognized on assets identified 
for disposal, non-recurring or one time income and expense items that were incurred outside normal operating activities 
such as integration costs, unrealized currency gains and losses and interest, tax, depreciation on unconsolidated joint 
ventures and fair value adjustments to contingent consideration obligations that originated with various acquisitions.
Represents the non-Argos USA transaction expenses associated with closed and probable acquisitions and divestitures, 
consisting primarily of accounting, legal, valuation and financial advisory fees.
Under the terms of our credit facilities, we include EBITDA from our acquisitions, net of dispositions, in each fiscal year 
for periods prior to acquisition. We believe this provides our lenders with a more meaningful view of our EBITDA

At December 30, 2023 and December 31, 2022, $2.3 billion and $1.5 billion of total debt was outstanding under our 

respective debt agreements, respectively. During 2022, we repaid $95.6 million of our term loan under provisions related to the 
divestitures of businesses. Summit LLC’s senior secured credit facilities provide for term loans in an aggregate amount of 
$504.5 million and revolving credit commitments in an aggregate amount of $395.0 million (the “Senior Secured Credit 
Facilities”). Summit LLC’s domestic wholly-owned subsidiary companies are named as guarantors of the Senior Notes and the 
Senior Secured Credit Facilities. Certain other partially-owned subsidiaries, and the wholly-owned Canadian subsidiary, 
Mainland, do not guarantee the Senior Notes or Senior Secured Credit Facilities. Summit LLC has pledged substantially all of 
its assets as collateral (other than real property and other customary exceptions) for the Senior Secured Credit Facilities.

Senior Notes

In December 2023, Summit LLC and Summit Finance (together, the “Issuers”) issued $800 million in aggregate 

principal amount of 7.25% senior notes due January 15, 2031 (“2031 Notes”). The 2031 Notes were issued at 100.0% of their 
par value. Interest on the 2031 Notes is payable semi-annually on January 15 and July 15 of each year commencing on July 15, 
2024. The gross proceeds of the 2031 Notes were held in escrow as of December 30, 2023 as the proceeds were restricted to use 
for the Argos USA cash consideration. In January 2024, the cash proceeds were released at closing of the Argos USA 
transaction.

On September 27, 2021, the Issuers redeemed all $300.0 million in aggregate principal amount of their 5.125% senior 

notes due June 1, 2025 (“2025 Notes”) using existing cash on hand at a price equal to par plus an applicable premium and the 
indenture under which the 2025 Notes were issued was satisfied and discharged. 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.

borrowings and a floor of 1.00% per annum or (ii) 2.50% per annum with respect to Term SOFR borrowings and a floor of zero 
(and no credit spread adjustment), (c) refinanced the $504.5 million of our existing senior secured term loans and increased the 
amount of term loans by an additional $505.5 million for a total aggregate principal amount of $1,010 million with a maturity 
date of January 10, 2029 and (d) reduced the applicable margin with respect to our existing term loans and which is applicable 
to our Term Loan Facility to (i) 1.50% per annum with respect to base rate borrowings and a floor of 1.00% per annum or (ii) 
2.50% per annum with respect to Term SOFR borrowings and a floor of zero (and no credit spread adjustment).

On January 10, 2023, Summit Materials, LLC entered into Amendment No. 6 to the Credit Agreement, which among 
other things, increased the maximum amount available under the Revolving Credit Facility to $395.0 million and extended the 
maturity date to January 10, 2028.

On December 14, 2022, Summit Materials, LLC entered into Amendment No. 5 to the Credit Agreement, which 

among other things, (a) refinanced the existing $509.6 million of existing term loans with new term loans under the Term Loan 
Facility and (b) extended the maturity date to December 14, 2027.

There were no outstanding borrowings under the Revolving Credit Facility as of December 30, 2023 or December 31, 
2022. As of December 30, 2023, we had remaining borrowing capacity of $374.1 million under the Revolving Credit Facility, 
which is net of $20.9 million of outstanding letters of credit. The outstanding letters of credit are renewed annually and support 
required bonding on construction projects and the Company’s insurance liabilities.

Summit LLC’s Consolidated First Lien Net Leverage Ratio, as such term is defined in the Credit Agreement, should 

be no greater than 4.75:1.0 as of each quarter-end. As of December 30, 2023 and December 31, 2022, Summit LLC was in 
compliance with all financial covenants under the Credit Agreement.

Summit LLC’s wholly-owned domestic subsidiary companies, subject to certain exclusions and exceptions, are named 

as subsidiary guarantors of the Senior Notes and the Senior Secured Credit Facilities. In addition, Summit LLC has pledged 
substantially all of its assets as collateral, with the exception of real property and subject to certain exclusions and exceptions, 
for the Senior Secured Credit Facilities.

Net income of $289.6 million, adjusted for $302.5 million of non-cash expenses, including $226.6 million of 
depreciation, depletion, amortization and accretion, $20.3 million of share-based compensation and $79.1 million of 
change in deferred tax asset, net, offset by the net gain on asset and business divestitures of $23.3 million.

Billed and unbilled accounts receivable increased by $30.0 million in fiscal 2023 as a result of our sales in the latter 
part of 2023 exceeding those levels of 2022.

The timing of payments associated with accounts payable and accrued expenses of cash, which is consistent with the 
seasonality of our business whereby we build-up inventory levels and incur repairs and maintenance costs to ready the 
business for increased sales volumes in the summer and fall. These costs are typically incurred in the first half of the 
year and paid by year-end. In addition, we made $99.0 million of interest payments in 2023.

• We recognized a tax receivable benefit of $154.2 million related to acquiring certain TRA interests at less than their 

carrying value.

During the year ended December 31, 2022, cash provided by operating activities was $284.1 million primarily as a 

result of:

•

•

•

Net income of $275.9 million, adjusted for $117.6 million of non-cash expenses, including $212.5 million of 
depreciation, depletion, amortization and accretion, $18.3 million of share-based compensation and $69.6 million of 
change in deferred tax asset, net, offset by the net gain on asset and business divestitures of $182.3 million.

Billed and unbilled accounts receivable decreased by $5.8 million in fiscal 2022 as a result of our sales in the latter part 
of 2022 exceeding those levels of 2021.

The timing of payments associated with accounts payable and accrued expenses of cash, which is consistent with the 
seasonality of our business whereby we build-up inventory levels and incur repairs and maintenance costs to ready the 
business for increased sales volumes in the summer and fall. These costs are typically incurred in the first half of the 
year and paid by year-end. In addition, we made $76.3 million of interest payments in 2022.

Investing Activities

During the year ended December 30, 2023, cash used for investing activities was $420.3 million, of which $255.6 

million was invested in capital expenditures and $239.5 million was used for acquisitions in the West and East segments, and 
was partially offset by $65.6 million of proceeds from the sale of businesses and $14.4 million of proceeds from asset sales. 

During the year ended December 31, 2022, cash provided by investing activities was $95.8 million, resulting from 

$373.1 million of proceeds from the sale of businesses, which more than offset $22.7 million related to acquisitions completed 
in the period and $266.7 million was invested in capital expenditures. In addition, during 2022, we received $15.4 million of 
proceeds from asset sales.

Financing Activities

During the year ended December 30, 2023, cash provided by financing activities was $633.8 million, primarily due to 

receiving $800.0 million from proceeds of debt issuance, partially offset by purchase of certain TRA interests for $132.4 
million. We made $10.4 million of payments on debt and $12.4 million of payments on acquisition related liabilities.

During the year ended December 31, 2022, cash used for financing activities was $239.0 million. We made $122.5 
million of payments on debt, including the $95.6 million prepayment of the term loan due to our divestiture program, $13.4 
million of payments on acquisition related liabilities and used $101.0 million to repurchase shares of Class A common stock.

Cash Paid for Capital Expenditures

We expended approximately $255.6 million in capital expenditures for the year ended December 30, 2023 compared 

to $266.7 million in the year ended December 31, 2022.

We estimate that we will invest between $430 million and $470 million in capital expenditures in 2024, which includes 

capital related to Argos USA. The timing of our greenfield expenditures is dependent upon the timing of when permits may be 
issued. We expect to fund our capital expenditure program through cash on hand, cash from operations, outside financing 
arrangements and available borrowings under our revolving credit facility.

Tax Receivable Agreement

Exchanges of LP Units for shares of Class A common stock are expected to result in increases in the tax basis of the 
tangible and intangible assets of Summit Holdings. These increases in tax basis may increase (for tax purposes) depreciation 
and amortization deductions and therefore reduce the amount of tax that Summit Inc. would otherwise be required to pay in the 

54

 
 
 
 
 
 
 
 
 
future. In connection with the IPO, we entered into a TRA with the holders of LP Units that provides for the payment by 
Summit Inc. to exchanging holders of LP Units of 85% of the benefits, if any, that Summit Inc. is deemed to realize as a result 
of these increases in tax basis and certain other tax benefits related to entering into the TRA, including tax benefits attributable 
to payments under the TRA. The increases in tax basis as a result of an exchange of LP Units for shares of Class A common 
stock, as well as the amount and timing of any payments under the TRA, are difficult to accurately estimate as they will vary 
depending upon a number of factors, including:

•

•

•

•

•

the timing of exchanges—for instance, the increase in any tax deductions will vary depending on the fair market value, 
which may fluctuate over time, of the depreciable or amortizable assets of Summit Holdings at the time of each 
exchange;

the price of shares of our Class A common stock at the time of the exchange—the increase in any tax deductions, as 
well as the tax basis increase in other assets, of Summit Holdings, is directly proportional to the price of shares of our 
Class A common stock at the time of the exchange;

the extent to which such exchanges are taxable—if an exchange is not taxable for any reason, increased deductions will 
not be available;

the amount and timing of our income—Summit Inc. is required to pay 85% of the cash tax savings, if any, as and when 
realized. If Summit Inc. does not have taxable income, Summit Inc. is not required (absent a change of control or 
circumstances requiring an early termination payment) to make payments under the TRA for that taxable year because 
no cash tax savings will have been realized. However, any tax attributes that do not result in realized benefits in a given 
tax year will likely generate tax attributes that may be utilized to generate benefits in previous or future tax years. The 
utilization of such tax attributes will result in cash tax savings that will result in payments under the tax receivable 
agreement; and

the effective tax rate – The benefit that Summit Inc. realizes is dependent on the tax rate in effect at the time taxable 
income is generated. 

In the second half of 2023, Summit LLC reached an agreement to acquire all of the rights and interests in the TRA 

from affiliates of Blackstone Inc. and certain other TRA holders for cash consideration of $132.4 million. In connection with 
these transactions, Summit LLC and Summit Inc. reached an agreement whereby the maximum amount Summit Inc is obligated 
to pay Summit LLC for the TRA interest is limited to the amount Summit LLC paid for the TRA interests. The cash paid for 
TRA interests acquired was less than their carrying value, accordingly Summit Inc. recognized a TRA benefit of $157.5 million 
in the accompanying consolidated statement of operations.

We anticipate funding payments under the TRA from cash flows from operations, available cash and available 
borrowings under our Revolving Credit Facility. As of December 30, 2023, we had accrued $41.7 million as TRA liability. Of 
the total TRA liability, $0.5 million is expected to be paid in the next twelve months.

In addition, the TRA provides that upon certain changes of control, Summit Inc.’s (or its successor’s) obligations 

would be based on certain assumptions, including that Summit Inc. would have sufficient taxable income to fully utilize the 
deductions arising from tax basis and other tax attributes subject to the TRA. With respect to our obligations under the TRA 
relating to previously exchanged or acquired LP Units and certain net operating losses, we would be required to make a 
payment equal to the present value (at a discount rate equal to one year SOFR plus 100 basis points) of the anticipated future 
tax benefits determined using assumptions (ii) through (v) of the following paragraph. In the second quarter 2023, the TRA 
agreement was amended to change the early termination calculation from a LIBOR based rate to a SOFR rate.

Furthermore, Summit Inc. may elect to terminate the TRA early by making an immediate payment equal to the present 

value of the anticipated future cash tax savings. In determining such anticipated future cash tax savings, the TRA includes 
several assumptions, including that (i) any LP Units that have not been exchanged are deemed exchanged for the market value 
of the shares of Class A common stock at the time of termination, (ii) Summit Inc. will have sufficient taxable income in each 
future taxable year to fully realize all potential tax savings, (iii) Summit Inc. will have sufficient taxable income to fully utilize 
any remaining net operating losses subject to the TRA on a straight line basis over the shorter of the statutory expiration period 
for such net operating losses or the five-year period after the early termination or change of control, (iv) the tax rates for future 
years will be those specified in the law as in effect at the time of termination and (v) certain non-amortizable assets are deemed 
disposed of within specified time periods. In addition, the present value of such anticipated future cash tax savings are 
discounted at a rate equal to SOFR plus 100 basis points.

55

 
 
 
 
 
 
As a result of the change in control provisions and the early termination right, Summit Inc. could be required to make 
payments under the TRA that are greater than or less than the specified percentage of the actual cash tax savings that Summit 
Inc. realizes in respect of the tax attributes subject to the TRA (although any such overpayment would be taken into account in 
calculating future payments, if any, under the TRA) or that are prior to the actual realization, if any, of such future tax benefits. 
Also, the obligations of Summit Inc. would be automatically accelerated and be immediately due and payable in the event that 
Summit Inc. breaches any of its material obligations under the agreement and in certain events of bankruptcy or liquidation. In 
these situations, our obligations under the TRA could have a substantial negative impact on our liquidity.

Under the terms of the TRA, we can terminate the TRA at any time, which would trigger a cash payment to the pre-

IPO owners. Based upon a $38.46 share price of our Class A common stock, which was the closing price on December 29, 
2023, and a contractually defined discount rate of 6.39%, we estimate that if Summit Inc. were to exercise its termination right, 
the aggregate amount of these termination payments would be approximately $32.3 million.

Future interest payments were calculated using the applicable fixed and floating rates charged by our lenders in effect as 
of December 30, 2023 and may differ from actual results.
Amounts represent purchase commitments entered into in the normal course of business, primarily for fuel purchases, the 
terms of which are generally one year.
The total amount payable under our TRA is estimated at $41.7 million as of December 30, 2023. Under the terms of the 
TRA, payment of amounts benefiting us is due to the pre-IPO owners within four months of the tax returns being 
submitted to the respective regulatory agencies when the benefits are realized. The estimated timing of TRA payments is 
subject to a number of factors, primarily around the timing of the generation of future taxable income in future years, 
which will be impacted by business activity in those periods.

Commitments and Contingencies

We are party to certain legal actions arising from the ordinary course of business activities. Accruals are recorded 

when the outcome is probable and can be reasonably estimated. While the ultimate results of claims and litigation cannot be 
predicted with certainty, management expects that the ultimate resolution of all pending or threatened claims and litigation will 
not have a material effect on our consolidated financial position, results of operations or liquidity. We record legal fees as 
incurred.

In March 2018, we were notified of an investigation by the CCB into pricing practices by certain asphalt paving 

contractors in British Columbia, including Winvan. We believe the investigation is focused on time periods prior to our April 
2017 acquisition of Winvan and we are cooperating with the CCB. Although we currently do not believe this matter will have a 
material adverse effect on our business, financial condition or results of operations, we are not able to predict the ultimate 
outcome or cost of the investigation at this time.

Environmental Remediation and Site Restoration—Our operations are subject to and affected by federal, state, 

provincial and local laws and regulations relating to the environment, health and safety and other regulatory matters. These 
operations require environmental operating permits, which are subject to modification, renewal and revocation. We regularly 
monitor and review its operations, procedures and policies for compliance with these laws and regulations. Despite these 
compliance efforts, risk of environmental liability is inherent in the operation of our business, as it is with other companies 
engaged in similar businesses and there can be no assurance that environmental liabilities and noncompliance will not have a 
material adverse effect on our consolidated financial condition, results of operations or liquidity.

Other—We are obligated under various firm purchase commitments for certain raw materials and services that are in 
the ordinary course of business. Management does not expect any significant changes in the market value of these goods and 
services during the commitment period that would have a material adverse effect on the financial condition, results of 
operations, and cash flows of the Company. The terms of the purchase commitments generally approximate one year.

Off-Balance Sheet Arrangements

As of December 30, 2023, we had no material off-balance sheet arrangements.

Non-GAAP Performance Measures

We evaluate our operating performance using metrics that we refer to as “Adjusted EBITDA,” “Adjusted EBITDA 
Margin,” “Adjusted Cash Gross Profit” and “Adjusted Cash Gross Profit Margin” which are not defined by U.S. GAAP and 
should not be considered as an alternative to earnings measures defined by U.S. GAAP. We define Adjusted EBITDA as 
EBITDA, adjusted to exclude accretion, loss on debt financings, gain on sale of business, non-cash compensation, Argos USA 
acquisition and integration costs and certain other non-cash and non-operating items. We define Adjusted EBITDA Margin as 
Adjusted EBITDA divided by net revenue. We define Adjusted Cash Gross Profit as operating income before general and 
administrative expenses, depreciation, depletion, amortization and accretion and Adjusted Cash Gross Profit Margin as 
Adjusted Cash Gross Profit as a percentage of net revenue.

We present Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Cash Gross Profit and Adjusted Cash Gross 

Profit Margin for the convenience of investment professionals who use such metrics in their analyses. The investment 
community often uses these metrics to assess the operating performance of a company’s business and to provide a consistent 
comparison of performance from period to period. We use these metrics, among others, to assess the operating performance of 
our individual segments and the consolidated company.

Non-GAAP financial measures are not standardized; therefore, it may not be possible to compare such financial 

measures with other companies’ non-GAAP financial measures having the same or similar names. We strongly encourage 
investors to review our consolidated financial statements in their entirety and not rely on any single financial measure.

The tables below reconcile our net income (loss) to EBITDA and Adjusted EBITDA, present Adjusted EBITDA by 

segment and reconcile operating income to Adjusted Cash Gross Profit for the periods indicated:

The reconciliation of net income (loss) to Adjusted EBITDA is based on the financial results of Summit Inc. and its 
subsidiaries, which was $79.7 million and $70.2 million less and $16.7 million more than Summit LLC and its 
subsidiaries in the years ended December 30, 2023, December 31, 2022 and January 1, 2022, respectively, due to interest 
expense associated with a deferred consideration obligation, TRA expense and income tax benefit which are obligations 
of Summit Holdings and Summit Inc., respectively, and are thus excluded from Summit LLC’s consolidated net income.
The adjustment for acquisition and integration costs related to the agreement to combine with Argos USA is comprised 
of finder's fees, advisory, legal and professional fees incurred relating to our agreement to combine with Argos USA.
Consists primarily of interest income earned on cash balances.
Adjusted EBITDA Margin is defined as Adjusted EBITDA as a percentage of net revenue for the applicable period.

Critical Accounting Policies and Estimates

Our management’s discussion and analysis of our financial condition and results of operations is based on our 
consolidated financial statements, which have been prepared in accordance with U.S. GAAP. The preparation of these 
consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of 

59

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the 
reported amounts of revenue and expenses during the reported period.

On an ongoing basis, management evaluates its estimates, including those related to the valuation of accounts 
receivable, inventories, goodwill, intangibles and other long-lived assets, pension and other postretirement obligations and asset 
retirement obligations. We base our estimates and judgments on historical experience and on various other factors that we 
believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying 
values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates 
under different assumptions or conditions.

Acquisitions—Purchase Price Allocation

We regularly review strategic long-term plans, including potential investments in value-added acquisitions of related 

or similar businesses, which would increase our market share and/or are related to our existing markets. When an acquisition is 
completed, our consolidated statement of operations includes the operating results of the acquired business starting from the 
date of acquisition, which is the date that control is obtained. The purchase price is determined based on the estimated fair value 
of assets given to and liabilities assumed from the seller as of the date of acquisition. We allocate the purchase price to the 
estimated fair values of the tangible and intangible assets acquired and liabilities assumed as valued at the date of acquisition. 
Goodwill is recorded for the excess of the purchase price over the net of the fair value of the identifiable assets acquired and 
liabilities assumed as of the acquisition date. The estimation of fair values of acquired assets and assumed liabilities is 
judgmental and requires various assumptions and the amounts and useful lives assigned to depreciable and amortizable assets 
compared to amounts assigned to goodwill, which is not amortized, can significantly affect the results of operations in the 
period of and periods subsequent to a business combination.

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction, and 

therefore represents an exit price. A fair value measurement assumes the highest and best use of the asset by market 
participants, considering the use of the asset that is physically possible, legally permissible, and financially feasible at the 
measurement date. We assign the highest level of fair value available to assets acquired and liabilities assumed based on the 
following options:

•

•

•

Level 1—Quoted prices in active markets for identical assets and liabilities.

Level 2—Observable inputs, other than quoted prices, for similar assets or liabilities in active markets.

Level 3—Unobservable inputs, which includes the use of valuation models.

Level 1 fair values are used to value investments in publicly-traded entities and assumed obligations for publicly-

traded long-term debt. 

Level 2 fair values are typically used to value acquired receivables, inventories, machinery and equipment, land, 

buildings, deferred income tax assets and liabilities, liabilities for asset retirement obligations, environmental remediation and 
compliance obligations. Additionally, Level 2 fair values are typically used to value assumed contracts at other-than-market 
rates.

Level 3 fair values are used to value acquired mineral reserves and leased mineral interests and other identifiable 
intangible assets. The fair values of mineral reserves and leased mineral interests are determined using an excess earnings 
approach, which requires management to estimate future cash flows. The estimate of future cash flows is based on available 
historical information and forecasts determined by management, but is inherently uncertain. Key assumptions in estimating 
future cash flows include sales price, volumes and expected profit margins, net of capital requirements. The present value of the 
projected net cash flows represents the fair value assigned to mineral reserves and mineral interests. The discount rate is a 
significant assumption used in the valuation model and is based on the required rate of return that a hypothetical market 
participant would assume if purchasing the acquired business.

There is a measurement period after the acquisition date during which we may adjust the amounts recognized for a 
business combination. Any such adjustments are based on us obtaining additional information that existed at the acquisition 
date regarding the assets acquired or the liabilities assumed. Measurement period adjustments are generally recorded as 
increases or decreases to the goodwill recognized in the transaction. The measurement period ends once we have obtained all 
necessary information that existed as of the acquisition date, but does not extend beyond one year from the date of acquisition. 
Any adjustments to assets acquired or liabilities assumed beyond the measurement period are recorded in earnings.

60

 
 
 
 
 
 
We paid cash of $239.5 million and $22.7 million, net of cash acquired, in business combinations and allocated this 

amount to assets acquired and liabilities assumed during the years ended December 30, 2023 and December 31, 2022, 
respectively.

Goodwill

Goodwill is tested annually for impairment and in interim periods if events occur indicating that the carrying amounts 

may be impaired. The evaluation involves the use of significant estimates and assumptions and considerable management 
judgment. Our judgments regarding the existence of impairment indicators and future cash flows are based on operational 
performance of our businesses, market conditions and other factors. Although there are inherent uncertainties in this assessment 
process, the estimates and assumptions we use, including estimates of future cash flows, volumes, market penetration and 
discount rates, are consistent with our internal planning. The estimated future cash flows are derived from internal operating 
budgets and forecasts for long-term demand and pricing in our industry and markets. If these estimates or their related 
assumptions change in the future, we may be required to record an impairment charge on all or a portion of our goodwill. 
Furthermore, we cannot predict the occurrence of future impairment-triggering events nor the affect such events might have on 
our reported values. Future events could cause us to conclude that impairment indicators exist and that goodwill associated with 
our acquired businesses are impaired. Any resulting impairment loss could have an adverse effect on our financial condition 
and results of operations.

The annual goodwill test is performed by first assessing qualitative factors to determine whether the existence of 
events or circumstances leads to a determination that it is more likely than not (more than 50%) that the estimated fair value of a 
reporting unit is less than its carrying amount. If, as a result of the qualitative assessment, it is determined that an impairment is 
more likely than not, a Step-1 approach is performed to quantitatively compare each reporting unit’s fair value to its carrying 
value. The Step-1 analysis fails when a report unit's carrying value is in excess of its fair value, resulting in an impairment loss.

Under the quantitative impairment test, Step-1 of the evaluation of impairment involves comparing the current fair 

value of each reporting unit to its carrying value, including goodwill. We use a discounted cash flow (“DCF”) model to estimate 
the current fair value of our reporting units when testing for impairment, as management believes forecasted cash flows are the 
best indicator of fair value. A number of significant assumptions and estimates are involved in the application of the DCF 
model to forecast operating cash flows, including macroeconomic trends in the reporting unit’s geographic area impacting 
private construction and public infrastructure industries, the timing of work embedded in our backlog, our performance and 
profitability under our contracts, our success in securing future sales and the appropriate interest rate used to discount the 
projected cash flows. We also perform a market assessment of our enterprise value. We believe the estimates and assumptions 
used in the valuations are reasonable.

In 2023, in conjunction with our annual review of goodwill on the first day of the fourth quarter, we selected a Step-1 
approach for all of our reporting units. As of December 30, 2023, we determined that no events or circumstances from October 
1, 2023 through December 30, 2023 indicated that a further assessment was necessary.

Service Revenue Recognition

We earn revenue from the provision of services, which are primarily paving and related services, but also include 

landfill operations and the receipt and disposal of waste that is converted to fuel for use in our cement plants. Revenue from the 
receipt of waste fuels is recognized when the waste is accepted and a corresponding liability is recognized for the costs to 
process the waste into fuel for the manufacturing of cement or to ship the waste offsite for disposal in accordance with 
applicable regulations.

Collectability of service contracts is due reasonably after certain milestones in the contract are performed. Milestones 

vary by project, but are typically calculated using monthly progress based on a percentage of completion or a customer’s 
engineer review of progress. The majority of the time, collection occurs within 90 days of billing and cash is received within 
the same fiscal year as services performed. On most projects the customer will withhold a portion of the invoice for retainage 
which may last longer than a year depending on the job.

Revenue derived from paving and related services is recognized over time based on the proportion of costs incurred to 

date relative to the total estimated costs at completion, which approximates progress towards completion. Under this method, 
we recognize paving and related services revenue as services are rendered. The majority of our construction service contracts 
are completed within one year, but may occasionally extend beyond this time frame. The majority of our construction service 
contracts, and therefore, revenue, are opened and completed within one year, with most activity during the spring, summer and 

61

 
 
 
 
 
 
 
 
 
fall. We generally measure progress toward completion on long-term paving and related services contracts based on the 
proportion of costs incurred to date relative to total estimated costs at completion. We include revisions of estimated profits on 
contracts in earnings under the cumulative catch-up method, under which the effect of revisions in estimates is recognized 
immediately. If a revised estimate of contract profitability reveals an anticipated loss on the contract, we recognize the loss in 
the period it is identified. 

Our method, which is similar to the percentage of completion method of accounting, involves the use of various 

estimating techniques to project costs at completion, and in some cases includes estimates of recoveries asserted against the 
customer for changes in specifications or other disputes. Contract estimates involve various assumptions and projections 
relative to the outcome of future events over multiple periods, including future labor productivity and availability, the nature 
and complexity of the work to be performed, the cost and availability of materials, the effect of delayed performance, and the 
availability and timing of funding from the customer. These estimates are based on our best judgment. A significant change in 
one or more of these estimates could affect the profitability of one or more of our contracts. We review our contract estimates 
regularly to assess revisions in contract values and estimated costs at completion. Inherent uncertainties in estimating costs 
make it at least reasonably possible that the estimates used will change within the near term and over the life of the contracts. 
No material adjustments to a contract were recognized in the year ended December 30, 2023.

We recognize claims when the amount of the claim can be estimated reliably and it is legally enforceable. In 
evaluating these criteria, we consider the contractual basis for the claim, the cause of any additional costs incurred, the 
reasonableness of those costs and the objective evidence available to support the claim.

When the contract includes variable consideration, we estimate the amount of consideration to which we will be 

entitled in exchange for transferring the promised goods or services to a customer. The amount of estimated variable 
consideration included in the transaction price is the amount for which it is probable that a significant reversal in the amount of 
cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently 
resolved. Types of variable consideration include, but are not limited to, liquidated damages and other performance penalties 
and production and placement bonuses. 

The majority of contract modifications relate to the original contract and are often an extension of the original 
performance obligation. Predominately, modifications are not distinct from the terms in the original contract; therefore, they are 
considered part of a single performance obligation. We account for the modification using a cumulative catch-up adjustment. 
However, there are instances where goods or services in a modification are distinct from those transferred prior to the 
modification. In these situations, we account for the modifications as either a separate contract or prospectively depending on 
the facts and circumstances of the modification. 

Generally, construction contracts contain mobilization costs which are categorized as costs to fulfill a contract. These 
costs are excluded from any measure of progress toward contract fulfillment. These costs do not result in the transfer of control 
of a good or service to the customer and are amortized over the life of the contract. 

Costs and estimated earnings in excess of billings are composed principally of revenue recognized on contracts on a 

method similar to the percentage of completion method for which billings had not been presented to customers because the 
amounts were not billable under the contract terms at the balance sheet date. In accordance with the contract terms, the unbilled 
receivables at the balance sheet date are expected to be billed in following periods. Billings in excess of costs and estimated 
earnings represent billings in excess of revenue recognized.

Income Taxes

Summit Inc. is a corporation subject to income taxes in the United States. Certain subsidiaries, including Summit 
Holdings, or subsidiary groups of the Company are taxable separate from Summit Inc. The provision for income taxes, or 
Summit Inc.’s proportional share of the provision, are included in the Company’s consolidated financial statements.

The Company’s deferred income tax assets and liabilities are computed for differences between the tax basis and 

financial statement amounts that will result in taxable or deductible amounts in the future. The ultimate realization of deferred 
tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences 
become deductible, as well as consideration of tax-planning strategies to determine whether we may seek to utilize any net 
operating loss carryforwards scheduled to expire in the near future. The estimates of future taxable income involves the use of 
significant estimates and assumptions and considerable management judgment. Our judgments regarding future taxable income 
and future cash flows are based on operational performance of our businesses, market conditions and other factors. Although 
there are inherent uncertainties in this assessment process, the estimates and assumptions we use, including estimates of future 

62

 
 
 
cash flows, are consistent with our internal planning. The computed deferred balances are based on enacted tax laws and 
applicable rates for the periods in which the differences are expected to affect taxable income. A valuation allowance is 
recognized for deferred tax assets if it is more likely than not that some portion or all of the net deferred tax assets will not be 
realized. In making such a determination, all available positive and negative evidence is considered, including future reversals 
of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent 
operations. If the Company determines it would be able to realize its deferred tax assets for which a valuation allowance had 
been recorded, then an adjustment would be made to the deferred tax asset valuation allowance, which would reduce the 
provision for income taxes. 

The Company evaluates the tax positions taken on income tax returns that remain open and positions expected to be 

taken on the current year tax returns to identify uncertain tax positions. Unrecognized tax benefits on uncertain tax positions are 
recorded on the basis of a two-step process in which (1) the Company determines whether it is more likely than not that the tax 
positions will be sustained on the basis of the technical merits of the position and (2) for those tax positions that meet the more-
likely-than-not recognition threshold, the largest amount of tax benefit that is more than 50 percent likely to be realized is 
recognized. Interest and penalties related to unrecognized tax benefits are recorded in income tax expense (benefit).

Tax Receivable Agreement

Tax Receivable Agreement— When Summit Inc. purchases LP Units for cash or LP Units are exchanged for shares of 

Class A common stock, this results in increases in Summit Inc.’s share of the tax basis of the tangible and intangible assets of 
Summit Holdings, which increases the tax depreciation and amortization deductions that otherwise would not have been 
available to Summit Inc. These increases in tax basis and tax depreciation and amortization deductions are expected to reduce 
the amount of cash taxes that we would otherwise be required to pay in the future. In connection with our IPO, we entered into 
a TRA with the holders of the LP Units and the pre-IPO owners that provides for the payment by Summit Inc. to exchanging 
holders of LP Units of 85% of the benefits, if any, that Summit Inc. actually realizes (or, under certain circumstances such as an 
early termination of the TRA is deemed to realize) as a result of (i) these increases in tax basis and (ii) our utilization of certain 
net operating losses of the pre-IPO owners and certain other tax benefits related to entering into the TRA, including tax benefits 
attributable to payments under the TRA. 

We periodically evaluate the realizability of the deferred tax assets resulting from the exchange of LP Units for Class 

A common stock. Our evaluation considers all sources of taxable income; all evidence, both positive and negative, is 
considered to determine whether, based on the weight of that evidence, a valuation allowance is needed for some portion or all 
of the deferred tax assets. If the deferred tax assets are determined to be realizable, we then assess whether payment of amounts 
under the TRA have become probable. If so, we record a TRA liability equal to 85% of such deferred tax assets. In subsequent 
periods, we assess the realizability of all of our deferred tax assets subject to the TRA. Should we determine a deferred tax asset 
with a valuation allowance is realizable in a subsequent period, the related valuation allowance will be released and 
consideration of a corresponding TRA liability will be assessed. The realizability of deferred tax assets, including those subject 
to the TRA, is dependent upon the generation of future taxable income during the periods in which those deferred tax assets 
become deductible and consideration of prudent and feasible tax-planning strategies.

The measurement of the TRA liability is accounted for as a contingent liability. Therefore, once we determine that a 

payment to a pre-IPO owner has become probable and can be estimated, the estimate of payment will be accrued.

New Accounting Pronouncements Not Yet Adopted

In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update 
("ASU") No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which requires additional 
information regarding income taxes paid and specific categories in the rate reconciliation. The ASU is effective for annual 
periods beginning after December 15, 2024. Early adoption is permitted. We are evaluating the additional disclosure 
requirements and beginning to assess the impact of adopting this ASU.

In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable 

Segment Disclosures, which expands disclosure about significant segment expenses. The ASU is effective for fiscal years 
beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption 
is permitted. We are evaluating the additional disclosure requirements and beginning to assess the impact of adopting this ASU.

ITEM 7A.  

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

63

 
 
 
 
 
We are exposed to certain market risks arising from transactions that are entered into in the normal course of business. 

Our operations are highly dependent upon the interest rate-sensitive construction industry as well as the general economic 
environment. Consequently, these marketplaces could experience lower levels of economic activity in an environment of rising 
interest rates or escalating costs. Management has considered the current economic environment and its potential effect to our 
business. Demand for materials-based products, particularly in the residential and nonresidential construction markets, could 
decline if companies and consumers are unable to obtain financing for construction projects or if an economic recession causes 
delays or cancellations to capital projects. Additionally, in preceding years, declining tax revenue, state budget deficits and 
unpredictable or inconsistent federal funding have negatively affected states’ abilities to finance infrastructure construction 
projects.

Commodity and Energy Price Risk

We are subject to commodity price risk with respect to price changes in liquid asphalt and energy, including fossil 

fuels and electricity for aggregates, cement, ready-mix concrete and asphalt paving mix production and diesel fuel for 
distribution vehicles and production related mobile equipment. Liquid asphalt escalators in most of our public infrastructure 
contracts limit our exposure to price fluctuations in this commodity, and we seek to obtain escalators on private and commercial 
contracts. Similarly, in periods of decreasing oil prices, a portion of the cost savings will be recouped by our end customers. 
Changes in oil prices also could affect demand in certain of our markets, particularly in Midland/Odessa, Texas and indirectly 
in Houston, Texas, which collectively represented approximately 14.8% of our consolidated revenue in 2023. In addition, we 
enter into various firm purchase commitments, with terms generally less than one year, for certain raw materials.

For the year ended December 30, 2023, our costs associated with liquid asphalt and energy amounted to approximately 

$295.1 million. Accordingly, a 10% increase or decrease in the total cost of liquid asphalt and energy would have decreased or 
increased, respectively, our operating results for the year by approximately $29.5 million. However, this does not take into 
consideration liquid asphalt escalators in certain contracts or forward purchase commitments put into place before December 
30, 2023.

Inflation Risk

Although there has been a significant increase in inflation recently, it has not had a substantial impact due to our ability 

to recover increasing costs by obtaining higher prices for our products, including sale price escalators in place for most public 
infrastructure sector contracts. Inflation risk varies with the level of activity in the construction industry, the number, size and 
strength of competitors and the availability of products to supply a local market. We continue to monitor inflationary impacts in 
our business, primarily labor, energy and raw materials, with the goal of passing along price increases to our customers to 
mitigate the full effect of inflation. 

Foreign Currency Risk

In 2014, we expanded our operations into Canada with the acquisition of Mainland. With this expansion, we became 
subject to foreign currency risk related to changes in the U.S. dollar/Canadian dollar exchange rates. A 10% adverse change in 
foreign currency rates from December 2023 levels would not have had a material effect on our financial condition, results of 
operations or liquidity.

Interest Rate Risk

As of December 30, 2023, we had $504.5 million in term loans outstanding which bear interest at a variable rate. As of 

December 30, 2023, the rate in effect was SOFR of 5.47%, plus a floor of 3.00% and 0.10% SOFR adjustment rate. Therefore, 
a 100 basis point increase in the interest rate at December 30, 2023 would only have increased the all-in rate from 8.57% to 
9.57%, the effect of which would have been an increase of $5.0 million on annual interest expense.

We have occasionally entered into interest rate derivatives on our term loan borrowings to add stability to interest 

expense and to manage exposure to interest rate movements, however, we have not done so recently. Our last derivative expired 
in September 2019.

Report of Independent Registered Public Accounting Firm

To the Stockholders and Board of Directors
Summit Materials, Inc.:

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Summit Materials, Inc. and subsidiaries (the Company) as of 
December 30, 2023 and December 31, 2022, the related consolidated statements of operations, comprehensive income, cash 
flows, and changes in stockholders’ equity, for each of the fiscal years in the three-year period ended December 30, 2023, and 
the related notes (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements 
present fairly, in all material respects, the financial position of the Company as of December 30, 2023 and December 31, 2022, 
and the results of its operations and its cash flows for each of the fiscal years in the three-year period ended December 30, 2023, 
in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) 
(PCAOB), the Company’s internal control over financial reporting as of December 30, 2023, based on criteria established in 
Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway 
Commission, and our report dated February 15, 2024 expressed an unqualified opinion on the effectiveness of the Company’s 
internal control over financial reporting.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express 
an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the 
PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and 
the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the 
audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, 
whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the 
consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such 
procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial 
statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, 
as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a 
reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial 
statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or 
disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or 
complex judgments. The communication of a critical audit matter does not alter in any way our opinion on the consolidated 
financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate 
opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Revenue recognized over time on paving and related services contracts

As discussed in notes 1 and 4 to the consolidated financial statements, the Company earns revenue from providing paving 
and related services, which are recognized over time as performance obligations are satisfied. The Company recognizes 
paving and related services revenue as services are rendered based on the proportion of costs incurred to date relative to 
total estimated costs to complete. For the year ended December 30, 2023, the Company recognized service revenue related 
to paving and related services of $305 million.

We identified the assessment of revenue recognized over time on paving and related services contracts in-progress as a 
critical audit matter. Paving and related services contracts in-progress required challenging auditor judgment to evaluate the 
forecast of remaining costs to complete, which had a significant impact on the amount of revenue recognized during the 
period. 

The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and 
tested the operating effectiveness of certain internal controls over the Company’s revenue recognition process related to 
paving and related services, including controls over the forecasting of estimated costs to complete. We selected a sample of 

66

 
 
in-progress paving and related services costs incurred and compared the amounts and dates incurred to underlying 
supporting documentation. We analyzed prior year end in-progress contracts that were completed in the current year to 
evaluate the Company’s ability to accurately estimate paving and related services contract forecasted costs to complete. For 
certain contracts, we evaluated the estimated costs to complete by performing project manager interviews to obtain an 
understanding of the facts and circumstances of each selected contract, including changes in scope to the contract, 
additional estimated costs to complete, and expected completion date. For certain contracts, we also confirmed with the 
Company’s customers that the original contract amount, terms of the contract, modifications and billings to the customer 
were accurate.

We have served as the Company’s auditor since 2012.

SUMMIT MATERIALS, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Dollars in tables in thousands, unless otherwise noted)

(1) Summary of Organization and Significant Accounting Policies

Summit Materials, Inc. (“Summit Inc.” and, together with its subsidiaries, “Summit,” “we,” “us,” “our” or the 
“Company”) is a vertically-integrated construction materials company. The Company is engaged in the production and sale of 
aggregates, cement, ready-mix concrete, asphalt paving mix and concrete products and owns and operates quarries, sand and 
gravel pits, two cement plants, cement distribution terminals, ready-mix concrete plants, asphalt plants and landfill sites. It is 
also engaged in paving and related services. The Company’s three operating and reporting segments are the West, East and 
Cement segments.

Substantially all of the Company’s construction materials, products and services are produced, consumed and 
performed outdoors, primarily in the spring, summer and fall. Seasonal changes and other weather-related conditions can affect 
the production and sales volumes of its products and delivery of services. Therefore, the financial results for any interim period 
are typically not indicative of the results expected for the full year. Furthermore, the Company’s sales and earnings are sensitive 
to national, regional and local economic conditions, weather conditions and to cyclical changes in construction spending, 
among other factors.

On September 23, 2014, Summit Inc. was formed as a Delaware corporation to be a holding company. Its sole material 
asset is a controlling equity interest in Summit Materials Holdings L.P. (“Summit Holdings”). Pursuant to a reorganization into 
a holding company structure (the “Reorganization”) consummated in connection with Summit Inc.’s March 2015 initial public 
offering ("IPO"), Summit Inc. became a holding corporation operating and controlling all of the business and affairs of Summit 
Holdings and its subsidiaries. Summit Inc. owns the majority of the partnership interests of Summit Holdings (see note 11, 
Stockholders’ Equity). Summit Materials, LLC (“Summit LLC”) an indirect wholly owned subsidiary of Summit Holdings, 
conducts the majority of our operations. Continental Cement Company, L.L.C. (“Continental Cement”) is also a wholly owned 
subsidiary of Summit LLC. Summit Materials Finance Corp. (“Summit Finance”), an indirect wholly owned subsidiary of 
Summit LLC, has jointly issued our Senior Notes as described below.

Principles of Consolidation—The consolidated financial statements include the accounts of Summit Inc. and its 

majority owned subsidiaries. All intercompany balances and transactions have been eliminated. As a result of the 
Reorganization, Summit Holdings became a variable interest entity over which Summit Inc. has 100% voting power and control 
and for which Summit Inc. has the obligation to absorb losses and the right to receive benefits.

The Company’s fiscal year is based on a 52-53 week year with each quarter composed of 13 weeks ending on a 

Saturday. The year ended January 2, 2021 was a 53-week year.

For a summary of the changes in Summit Inc.’s ownership of Summit Holdings, see Note 11, Stockholders’ Equity.

The Company attributes consolidated stockholders’ equity and net income separately to the controlling and 

noncontrolling interests. The Company accounted for investments in entities for which it has an ownership of 20% to 50% 
using the equity method of accounting.

Use of Estimates—Preparation of these consolidated financial statements in conformity with U.S. generally accepted 

accounting principles (“U.S. GAAP”) requires management to make estimates and assumptions. These estimates and the 
underlying assumptions affect the amounts of assets and liabilities reported, disclosures about contingent assets and liabilities 
and reported amounts of revenue and expenses. Such estimates include the valuation of accounts receivable, inventories, 
valuation of deferred tax assets, goodwill, intangibles and other long-lived assets, tax receivable agreement (“TRA”) liability, 
pension and other postretirement obligations, and asset retirement obligations. Estimates also include revenue earned on 
contracts and costs to complete contracts. Most of the Company’s paving and related services are performed under fixed unit-
price contracts with state and local governmental entities. Management regularly evaluates its estimates and assumptions based 
on historical experience and other factors, including the current economic environment. As future events and their effects 
cannot be determined with precision, actual results can differ significantly from estimates made. Changes in estimates, 
including those resulting from continuing changes in the economic environment, are reflected in the Company’s consolidated 
financial statements when the change in estimate occurs.  

73

 
 
 
 
 
 
 
 
 
 
 
 
Business and Credit Concentrations—The Company’s operations are conducted primarily across 21 U.S. states and 

in British Columbia, Canada, with the most significant revenue generated in Texas, Utah, Missouri and Kansas. The Company’s 
accounts receivable consist primarily of amounts due from customers within these areas. Therefore, collection of these accounts 
is dependent on the economic conditions in the aforementioned states, as well as specific situations affecting individual 
customers. Credit granted within the Company’s trade areas has been granted to many customers and management does not 
believe that a significant concentration of credit exists with respect to any individual customer or group of customers. No single 
customer accounted for more than 10% of the Company’s total revenue in 2023, 2022 or 2021.

Accounts Receivable—Accounts receivable are stated at the amount management expects to collect from outstanding 

balances. Management provides for probable uncollectible amounts through a charge to earnings and a credit to a valuation 
allowance based on its assessment of the collectability of individual accounts. In establishing the allowance, management 
considers historical losses adjusted to take into account current market conditions and its customers’ financial condition, the 
amount of receivables in dispute, the current receivables aging and current payment terms. Balances that remain outstanding 
after reasonable collection efforts are exercised are written off through a charge to the valuation allowance.

The balances billed but not paid by customers, pursuant to retainage provisions included in contracts, are generally due 

upon completion of the contracts.

Revenue Recognition—We earn revenue from the sale of products, which primarily include aggregates, cement, 

ready-mix concrete and asphalt, but also include concrete products and plastics components, and from the provision of services, 
which are primarily paving and related services, but also include landfill operations, the receipt and disposal of waste that is 
converted to fuel for use in our cement plants. 

Products 

We earn revenue from the sale of products, which primarily include aggregates, cement, ready-mix concrete and 

asphalt, but also include concrete products, net of discounts or allowances, if any, and freight and delivery charges billed to 
customers. Revenue for product sales is recognized when the performance obligation is satisfied, which generally is when the 
product is shipped. 

Aggregates and cement products are sold point-of-sale through purchase orders. When the product is sold on account, 

collectability typically occurs 30 to 60 days after the sale. Revenue is recognized when cash is received from the customer at 
the point of sale or when the products are delivered or collected on site. There are no other timing implications that will create a 
contract asset or liability, and contract modifications are unlikely given the timing and nature of the transaction. Material sales 
are likely to have multiple performance obligations if the product is sold with delivery. In these instances, delivery most often 
occurs on the same day as the control of the product transfers to the customer. As a result, even in the case of multiple 
performance obligations, the performance obligations are satisfied concurrently and revenue is recognized simultaneously. 

Services

We earn revenue from the provision of services, which are primarily paving and related services, but also include 

landfill operations and the receipt and disposal of waste that is converted to fuel for use in our cement plants. Revenue from the 
receipt of waste fuels is recognized when the waste is accepted and a corresponding liability is recognized for the costs to 
process the waste into fuel for the manufacturing of cement or to ship the waste offsite for disposal in accordance with 
applicable regulations.

Collectability of service contracts is due reasonably after certain milestones in the contract are performed. Milestones 

vary by project, but are typically calculated using monthly progress based on a percentage of completion or a customer’s 
engineer review of progress. The majority of the time, collection occurs within 90 days of billing and cash is received within 
the same fiscal year as services performed. On most projects, the customer will withhold a portion of the invoice for retainage, 
which may last longer than a year depending on the job. 

Revenue derived from paving and related services is recognized over time based on the proportion of costs incurred to 

date relative to the total estimated costs at completion, which approximates progress towards completion. Under this method, 
we recognize paving and related services revenue as services are rendered. The majority of our construction service contracts 
are completed within one year, but may occasionally extend beyond this time frame. The majority of our construction service 
contracts, and therefore, revenue, are opened and completed within one year, with most activity during the spring, summer and 
fall. We generally measure progress toward completion on long-term paving and related services contracts based on the 
proportion of costs incurred to date relative to total estimated costs at completion. We include revisions of revenue on contracts 

74

 
 
 
 
in earnings under the cumulative catch-up method, under which the effect of revisions in estimates is recognized immediately. 
If a revised estimate of contract profitability reveals an anticipated loss on the contract, we recognize the loss in the period it is 
identified. 

The actual cost to total estimated cost method of accounting involves the use of various estimating techniques to 

project costs at completion, and in some cases includes estimates of recoveries asserted against the customer for changes in 
specifications or other disputes. Contract estimates involve various assumptions and projections relative to the outcome of 
future events over multiple periods, including future labor productivity and availability, the nature and complexity of the work 
to be performed, the cost and availability of materials, the effect of delayed performance, and the availability and timing of 
funding from the customer. These estimates are based on our best judgment. A significant change in one or more of these 
estimates could affect the profitability of one or more of our contracts. We review our contract estimates regularly to assess 
revisions in contract values and estimated costs at completion. Inherent uncertainties in estimating costs make it at least 
reasonably possible that the estimates used will change within the near term and over the life of the contracts. No material 
adjustments to a contract were recognized in the year ended December 30, 2023.

We recognize claims when the amount of the claim can be estimated reliably and it is legally enforceable. In 
evaluating these criteria, we consider the contractual basis for the claim, the cause of any additional costs incurred, the 
reasonableness of those costs and the objective evidence available to support the claim.

When the contract includes variable consideration, we estimate the amount of consideration to which we will be 

entitled in exchange for transferring the promised goods or services to a customer. The amount of estimated variable 
consideration included in the transaction price is the amount for which it is probable that a significant reversal in the amount of 
cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently 
resolved. Types of variable consideration include, but are not limited to, liquidated damages and other performance penalties 
and production and placement bonuses. 

The majority of contract modifications relate to the original contract and are often an extension of the original 
performance obligation. Predominately, modifications are not distinct from the terms in the original contract; therefore, they are 
considered part of a single performance obligation. We account for the modification using a cumulative catch-up adjustment. 
However, there are instances where goods or services in a modification are distinct from those transferred prior to the 
modification. In these situations, we account for the modifications as either a separate contract or prospectively depending on 
the facts and circumstances of the modification. 

Generally, construction contracts contain mobilization costs which are categorized as costs to fulfill a contract. These 
costs are excluded from any measure of progress toward contract fulfillment. These costs do not result in the transfer of control 
of a good or service to the customer and are amortized over the life of the contract. 

Costs and estimated earnings in excess of billings are composed principally of revenue recognized on contracts on a 

method similar to the percentage of completion method for which billings had not been presented to customers because the 
amounts were not billable under the contract terms at the balance sheet date. In accordance with the contract terms, the unbilled 
receivables at the balance sheet date are expected to be billed in following periods. Billings in excess of costs and estimated 
earnings represent billings in excess of revenue recognized.

Restricted Cash - In December 2023, we issued $800 million of 7.250% senior notes due January 15, 2031 (the “2031 

Notes”) related to our merger with Argos North America Corporation (see notes 8 and 20). As the proceeds from the issuance 
of the 2031 Notes could only be used for the Argos transaction, the balance is shown as restricted cash as of December 30, 
2023. Subsequent to year end, the proceeds were released and used to consummate the Argos Transaction.

Inventories—Inventories consist of stone that has been removed from quarries and processed for future sale, cement, 
raw materials and finished concrete blocks. Inventories are valued at the lower of cost or net realizable value and are accounted 
for on a first-in first-out basis or an average cost basis. If items become obsolete or otherwise unusable or if quantities exceed 
what is projected to be sold within a reasonable period of time, they will be charged to costs of revenue in the period that the 
items are designated as obsolete or excess inventory. Stripping costs are costs of removing overburden and waste material to 
access aggregate materials and are expensed as incurred.

Property, Plant and Equipment, net—Property, plant and equipment are recorded at cost, less accumulated 
depreciation, depletion and amortization. Expenditures for additions and improvements that significantly add to the productive 
capacity or extend the useful life of an asset are capitalized. Repair and maintenance costs that do not substantially expand 
productive capacity or extend the life of property, plant and equipment are expensed as incurred.

75

 
 
Landfill airspace is included in property, plant and equipment at cost and is amortized based on the portion of the 

airspace used during the period compared to the gross estimated value of available airspace, which is updated periodically as 
circumstances dictate. Management reassesses the landfill airspace capacity with any changes in value recorded in cost of 
revenue. Capitalized landfill costs include expenditures for the acquisition of land and related airspace, engineering and 
permitting costs, cell construction costs and direct site improvement costs.

Upon disposal of an asset, the cost and related accumulated depreciation are removed from the Company’s accounts 

and any gain or loss is included in general and administrative expenses.

The Company reviews the carrying value of property, plant and equipment for impairment whenever events or 
circumstances indicate that the carrying value of an asset may not be recoverable from the estimated future cash flows expected 
to result from its use and eventual disposition. Such indicators may include, among others, deterioration in general economic 
conditions, adverse changes in the markets in which an entity operates, increases in input costs that have a negative effect on 
earnings and cash flows or a trend of negative or declining cash flows over multiple periods.

Property, plant and equipment is tested for impairment at the lowest level for which identifiable cash flows are largely 
independent of the cash flows of other assets. As a result, the property, plant and equipment impairment test is at a significantly 
lower level than the level at which goodwill is tested for impairment. In markets where the Company does not produce 
downstream products, such as ready-mix concrete, asphalt paving mix and paving and related services, the lowest level of 
largely independent identifiable cash flows is at the individual aggregates operation or a group of aggregates operations 
collectively serving a local market or the cement operations. Conversely, in vertically-integrated markets, the cash flows of the 
downstream and upstream businesses are not largely independently identifiable and the vertically-integrated operations are 
considered the lowest level of largely independent identifiable cash flows.

Aggregates mineral bearing land and interests are included in property, plant and equipment. When leased mineral 

interests are acquired during a business combination, they are valued using an excess earnings approach for the life of the 
proven and probable reserves. Depletion expense is recorded using a units of production methodology.

Accrued Mining and Landfill Reclamation—The mining reclamation reserve and financial commitments for landfill 

closure and post-closure activities are based on management’s estimate of future cost requirements to reclaim property at both 
currently operating and closed sites. Estimates of these obligations have been developed based on management’s interpretation 
of current requirements and proposed regulatory changes and are intended to approximate fair value. Costs are estimated in 
current dollars, inflated until the expected time of payment, and then discounted back to present value using a credit-adjusted 
risk-free rate on obligations of similar maturity, adjusted to reflect the Company’s credit rating. Changes in the credit-adjusted 
risk-free rate do not change recorded liabilities. However, subsequent increases in the recognized obligations are measured 
using a current credit-adjusted risk-free rate. Decreases in the recognized obligations are measured at the initial credit-adjusted 
risk-free rate.

Significant changes in inflation rates, or the amount or, timing of future cost estimates typically result in both (1) a 
current adjustment to the recorded liability (and corresponding adjustment to the asset) and (2) a change in accretion of the 
liability and depreciation of the asset to be recorded prospectively over the remaining capacity of the unmined quarry or 
landfill.

Goodwill—Goodwill represents the purchase price paid in excess of the fair value of net tangible and intangible assets 

acquired. Goodwill recorded in connection with the Company’s acquisitions is primarily attributable to the expected 
profitability, assembled workforces of the acquired businesses and the synergies expected to arise after the Company’s 
acquisition of those businesses. Goodwill is not amortized, but is tested annually for impairment as of the first day of the fourth 
quarter and at any time that events or circumstances indicate that goodwill may be impaired. A qualitative approach may first be 
applied to determine whether it is more likely than not that the estimated fair value of a reporting unit is less than its carrying 
amount. If, as a result of the qualitative assessment, it is determined that an impairment is more likely than not, a Step-1 
approach is performed to quantitatively compare each reporting unit’s fair value to its carrying value. The Step-1 analysis fails 
when a reporting unit's carrying value is in excess of its fair value, resulting in an impairment loss.

Transaction and Integration Expenses—Transaction and integration expenses typically include finders fees, legal, 

accounting and other professional costs. Integration expenses represent costs incurred to combine the company and its acquired 
businesses. Integration expenses typically include strategic consulting services, facility consolidations, one time employee 
related costs such as retention and severance costs, costs of integrating information system infrastructure, enterprise planning 
systems, processes, and other non-recurring integration related costs. Costs incurred related to the revision or issuance of new 

76

 
 
 
 
 
 
 
 
 
debt to finance the transactions are recorded as deferred financing costs. Transaction and integration costs are combined and 
presented on one line item in the consolidated statements of operations.

Income Taxes—Summit Inc. is a corporation subject to income taxes in the United States. Certain subsidiaries, 

including Summit Holdings, or subsidiary groups of the Company are taxable separate from Summit Inc. The provision for 
income taxes, or Summit Inc.’s proportional share of the provision, are included in the Company’s consolidated financial 
statements.

The Company’s deferred income tax assets and liabilities are computed for differences between the tax basis and 

financial statement amounts that will result in taxable or deductible amounts in the future. The computed deferred balances are 
based on enacted tax laws and applicable rates for the periods in which the differences are expected to affect taxable income. A 
valuation allowance is recognized for deferred tax assets if it is more likely than not that some portion or all of the net deferred 
tax assets will not be realized. In making such a determination, all available positive and negative evidence is considered, 
including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, 
and results of recent operations. If the Company determines it would be able to realize its deferred tax assets for which a 
valuation allowance had been recorded then an adjustment would be made to the deferred tax asset valuation allowance, which 
would reduce the provision for income taxes.

The Company evaluates the tax positions taken on income tax returns that remain open and positions expected to be 

taken on the current year tax returns to identify uncertain tax positions. Unrecognized tax benefits on uncertain tax positions are 
recorded on the basis of a two-step process in which (1) the Company determines whether it is more likely than not that the tax 
positions will be sustained on the basis of the technical merits of the position and (2) for those tax positions that meet the more-
likely-than-not recognition threshold, the largest amount of tax benefit that is more than 50 percent likely to be realized is 
recognized. Interest and penalties related to unrecognized tax benefits are recorded in income tax expense (benefit).

Tax Receivable Agreement—When Class A limited partnership units of Summit Holdings (“LP Units”) are 

exchanged for shares of Class A common stock of Summit Inc. or Summit Inc. purchases LP Units for cash, this results in 
increases in Summit Inc.’s share of the tax basis of the tangible and intangible assets, which increases the tax depreciation and 
amortization deductions that otherwise would not have been available to Summit Inc. These increases in tax basis and tax 
depreciation and amortization deductions are expected to reduce the amount of cash taxes that we would otherwise be required 
to pay in the future. Prior to our IPO, we entered into a TRA with the pre-IPO owners that requires us to pay the pre-IPO 
owners or their permitted assignees 85% of the amount of cash savings, if any, in U.S. federal, state, and local income tax that 
we actually realize as a result of these exchanges. These benefits include (1) increases in the tax basis of tangible and intangible 
assets of Summit Holdings and certain other tax benefits related to entering into the TRA, (2) tax benefits attributable to 
payments under the TRA, or (3) under certain circumstances such as an early termination of the TRA, we are deemed to realize, 
as a result of the increases in tax basis in connection with exchanges by the pre-IPO owners described above and certain other 
tax benefits attributable to payments under the TRA.

As noted above, we periodically evaluate the realizability of the deferred tax assets resulting from the exchange of LP 
Units for Class A common stock. If the deferred tax assets are determined to be realizable, we then assess whether payment of 
amounts under the TRA have become probable. If so, we record a TRA liability equal to 85% of such deferred tax assets. In 
subsequent periods, we assess the realizability of all of our deferred tax assets subject to the TRA. Should we determine a 
deferred tax asset with a valuation allowance is realizable in a subsequent period, the related valuation allowance will be 
released and consideration of a corresponding TRA liability will be assessed. The realizability of deferred tax assets, including 
those subject to the TRA, is dependent upon the generation of future taxable income during the periods in which those deferred 
tax assets become deductible and consideration of prudent and feasible tax-planning strategies.

The measurement of the TRA liability is accounted for as a contingent liability. Therefore, once we determine that a 

payment to a pre-IPO owner has become probable and can be estimated, the estimate of payment will be accrued.

Earnings per Share—The Company computes basic earnings per share attributable to stockholders by dividing 

income attributable to Summit Inc. by the weighted-average shares of Class A common stock outstanding. Diluted earnings per 
share reflects the potential dilution beyond shares for basic earnings per share that could occur if securities or other contracts to 
issue common stock were exercised, converted into common stock, or resulted in the issuance of common stock that would 
have shared in the Company’s earnings. Since the Class B common stock has no economic value, those shares are not included 
in the weighted-average common share amount for basic or diluted earnings per share. In addition, as the shares of Class A 
common stock are issued by Summit Inc., the earnings and equity interests of noncontrolling interests are not included in basic 
earnings per share.

Prior Year Reclassifications—We have reclassified transaction costs of $3.4 million and $3.3 million for the years 
ended December 31, 2022 and January 1, 2022, respectively, from general and administrative expenses to a separate line item 
included in operating income to conform to the current year presentation.

(2) Acquisitions and Dispositions

The Company has completed numerous acquisitions since its formation. The operations of each acquisition have been 

included in the Company’s consolidated results of operations since the respective closing dates of the acquisitions. The 
Company measures all assets acquired and liabilities assumed at their acquisition-date fair value. Goodwill acquired during a 
business combination has an indefinite life and is not amortized. The following table summarizes the Company’s acquisitions 
by region and period:

Acquisition-Related Liabilities—A number of acquisition-related liabilities have been recorded subject to terms in 
the relevant purchase agreements, including deferred consideration and noncompete payments. Noncompete payments have 
been accrued where certain former owners of newly acquired companies have entered into standard noncompete arrangements. 
Subject to terms and conditions stated in these noncompete agreements, payments are generally made over a five-year period. 
Deferred consideration is purchase price consideration paid in the future as agreed to in the purchase agreement and is not 
contingent on future events. Deferred consideration is generally scheduled to be paid in years ranging from 5 to 20 years in 
annual installments. The remaining payments due under these noncompete and deferred consideration agreements are as 
follows:

During 2023, as part of the Company's Elevate Summit strategy to rationalize assets, the Company sold two businesses 
in the West segment, resulting in total cash proceeds of $65.6 million and a net gain on disposition of business of $15.0 million.

During 2022, as part of the Company's Elevate Summit strategy to rationalize assets, the Company sold three 
businesses in the East segment, resulting in total cash proceeds of $373.1 million and a net gain on disposition of business of 
$172.4 million.

(3) Goodwill

As of December 30, 2023, the Company had nine reporting units with goodwill for which the annual goodwill 
impairment test was completed. We perform the annual impairment test on the first day of the fourth quarter each year. In 2023, 
we performed a Step-1 analysis on four of our reporting units and a Step 0 qualitative assessment on five of our reporting units. 
Based on this analysis, it was determined that the reporting units’ fair values were greater than their carrying values and no 
impairment charges were recognized in 2023.

These estimates of a reporting unit’s fair value involve significant management estimates and assumptions, including 
but not limited to sales prices of similar assets, assumptions related to future profitability, cash flows, and discount rates. These 
estimates are based upon historical trends, management’s knowledge and experience and overall economic factors, including 
projections of future earnings potential. Developing discounted future cash flow estimates in applying the income approach 
required management to evaluate its intermediate to longer-term strategies, including, but not limited to, estimates about 
revenue growth, operating margins, capital requirements, inflation and working capital management. The development of 
appropriate rates to discount the estimated future cash flows required the selection of risk premiums, which can materially 
affect the present value of estimated future cash flows.

We derive our revenue predominantly by selling construction materials, products and providing paving and related 

services. Construction materials consist of aggregates and cement. Products consist of related downstream products, including 
ready-mix concrete, asphalt paving mix and concrete products. Paving and related service revenue is generated primarily from 
the asphalt paving services that we provide, and is recognized based on the proportion of costs incurred to date relative to the 
total estimated costs at completion. The majority of our construction service contracts, and therefore revenue, are opened and 
completed within one year, with the most activity during the spring, summer and fall.

Revenue by product for the years ended December 30, 2023, December 31, 2022 and January 1, 2022 consisted of the

Depreciation on property, plant and equipment, including assets subject to capital leases, is generally computed on a 

straight-line basis. Depletion of mineral reserves and leased mineral interests are computed based on the portion of the reserves 
used during the period compared to the gross estimated value of proven and probable reserves, which is updated periodically as 
circumstances dictate. Leasehold improvements are amortized on a straight-line basis over the lesser of the asset’s useful life or 
the remaining lease term. The estimated useful lives are generally as follows:

Buildings and improvements
Plant, machinery and equipment
Office equipment
Truck and auto fleet
Mobile equipment and barges
Landfill airspace and improvements
Other

10 - 30 years
7 - 20 years
3 - 7 years
5 - 8 years
6 - 8 years
10 - 30 years
4 - 20 years

Depreciation, depletion and amortization expense of property, plant and equipment was $201.3 million, $184.3 million 

and $195.1 million in the years ended December 30, 2023, December 31, 2022 and January 1, 2022, respectively.

Property, plant and equipment at December 30, 2023 and December 31, 2022 included $30.1 million and 
$32.1 million, respectively, of finance leases for certain equipment and a building with accumulated amortization of $12.1 
million and $15.0 million, respectively. The equipment leases generally have terms of less than five years and the building lease 
had an original term of 30 years. Approximately $4.0 million and $7.0 million of the future obligations associated with the 
finance leases are included in accrued expenses as of December 30, 2023 and December 31, 2022, respectively, and the present 
value of the remaining finance lease payments, $14.4 million and $7.2 million, respectively, is included in other noncurrent 
liabilities on the consolidated balance sheets. Future minimum rental commitments under long-term finance leases are $5.2 
million, $4.2 million, $2.8 million, $2.6 million, and $2.4 million for the years ended 2024, 2025, 2026, 2027 and 2028, 
respectively.

Assets are assessed for impairment charges when identified for disposition. No material impairment charges have been 

recognized on assets held for use in fiscal 2023, 2022 or 2021.

Intangible Assets—The Company’s intangible assets subject to amortization are primarily composed of operating 

permits, mineral lease agreements and reserve rights. Operating permits relate to permitting and zoning rights acquired outside 
of a business combination. The assets related to mineral lease agreements reflect the submarket royalty rates paid under 
agreements, primarily for extracting aggregates. The values were determined as of the respective acquisition dates by a 
comparison of market-royalty rates. The reserve rights relate to aggregate reserves to which the Company has the rights of 
ownership, but does not own the reserves. The intangible assets are amortized on a straight-line basis over the lives of the leases 
or permits, or computed based on the portion of the reserves used during the period compared to the gross estimated value of 
proven and probable reserves. The following table shows intangible assets by type and in total:

Senior Notes—On December 14, 2023, Summit LLC and Summit Finance (together, the “Issuers”) issued 

$800.0 million in aggregate principal amount of 7.250% senior notes due January 15, 2031 (the “2031 Notes”). The 2031 Notes 
were issued at 100.0% of their par value. The 2031 Notes were issued under an indenture dated as of December 14, 2023 (the 
"2031 Notes Indenture"). The 2031 Notes Indenture contains covenants limiting, among other things, Summit LLC and its 
restricted subsidiaries’ ability to incur additional indebtedness or issue certain preferred shares, pay dividends, redeem stock or 
make other distributions, make certain investments, sell or transfer certain assets, create liens, consolidate, merge, sell or 
otherwise dispose of all or substantially all of its assets, enter into certain transactions with affiliates, and designate subsidiaries 
as unrestricted subsidiaries. The 2031 Notes Indenture also contains customary events of default. The gross proceeds of the 
2031 Notes were held in escrow as of December 30, 2023 as the proceeds were restricted to use for the Argos USA cash 
consideration. The proceeds were released upon closing of the Argos USA Transaction on January 12, 2024 (see note 20). 
Interest on the 2031 Notes is payable semi-annually on January 15 and July 15 of each year commencing on July 15, 2024.

On September 27, 2021, the Issuers redeemed all $300.0 million in aggregate principal amount of their 5.125% senior 

notes due June 1, 2025 (the "2025 Notes") using existing cash on hand at a price equal to par plus an applicable premium and 
the indenture under which the 2025 Notes were issued was satisfied and discharged. 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.

On August 11, 2020, the Issuers issued $700.0 million in aggregate principal amount of 5.250% senior notes due 

January 15, 2029 (the “2029 Notes”). The 2029 Notes were issued at 100.0% of their par value with proceeds of $690.4 million, 
net of related fees and expenses. The 2029 Notes were issued under an indenture dated August 11, 2020, the terms of which are 
generally consistent with the 2031 Notes Indenture. Interest on the 2029 Notes is payable semi-annually on January 15 and July 
15 of each year commencing on January 15, 2021.

In August 2020, using the proceeds from the 2029 Notes, all of the outstanding $650.0 million 6.125% senior notes 

due 2023 (the “2023 Notes”) were redeemed at a price equal to par and the indenture under which the 2023 Notes were issued 
was satisfied and discharged. As a result of the extinguishment, charges of $4.1 million were recognized in the quarter ended 
September 26, 2020, which included charges of $0.8 million for the write-off of original issue discount and $3.3 million for the 
write-off of deferred financing fees.

On March 15, 2019, the Issuers issued $300.0 million in aggregate principal amount of 6.500% senior notes due March 

15, 2027 (the “2027 Notes”). The 2027 Notes were issued at 100.0% of their par value with proceeds of $296.3 million, net of 
related fees and expenses. The 2027 Notes were issued under an indenture dated March 25, 2019, the terms of which are 
generally consistent with the 2031 Notes Indenture. Interest on the 2027 Notes is payable semi-annually on March 15 and 
September 15 of each year commencing on September 15, 2019.

As of December 30, 2023 and December 31, 2022, the Company was in compliance with all covenants under the 

applicable indentures.

Senior Secured Credit Facilities—As of December 30, 2023, Summit LLC had credit facilities that provide for term 

loans in an aggregate amount of $504.5 million and revolving credit commitments in an aggregate amount of $395.0 million 
(the “Senior Secured Credit Facilities”). Under the Senior Secured Credit Facilities, required quarterly amortization payments 
of 0.25% of the refinanced aggregate amount of term debt are due on the last business day of each March, June, September and 
December, commencing with the March 2023 payment. The interest rate on the term loan is variable based on either the base 
rate or Term SOFR rate and an applicable margin of (i) 2.00% per annum with respect to base rate borrowings and a floor of 
1.00% per annum or (ii) 3.00% per annum with respect to Term SOFR borrowings, with a SOFR adjustment of 0.10% per 
annum and a floor of zero. The interest rate on the term loan was 8.57% as of December 30, 2023. In 2022, the Company repaid 
$95.6 million of its term loan under provisions related to divestitures of businesses. The unpaid principal balance is due in full 
on the maturity date, which is December 14, 2027.

On January 12, 2024, Summit Materials, LLC entered into Amendment No. 7 to the credit agreement governing the 

Senior Secured Credit Facilities (the “Credit Agreement”), which among other things:

(1) establish new term loans in an aggregate principal amount of $1.010 billion (the "Term Loan Facility") bearing 

interest, at Summit LLC’s option, based on either the base rate or Term SOFR rate and an applicable margin of (i) 1.50% per 
annum with respect to base rate borrowings and a floor of 1.00% per annum or (ii) 2.50% per annum with respect to Term 
SOFR borrowings and a floor of zero, resulting in a current interest rate at the date of closing of 7.83%. Amendment No. 7 also 
extended the maturity date for the Term Loan Facility to January 12, 2029. In addition, the new term loan is subject to a 1.00% 
prepayment premium in respect of any principal amount repaid in connection with certain repricing transactions occurring 
within six months following the Amendment No. 7 Effective Date and requires quarterly amortization payments of 0.25% of 
the principal amount of the Term Loan Facility on the Amendment No. 7 effective date and due on the last business day or each 
March, June, September and December, commencing with the June 2024 payment. The proceeds of the new term loans were 
used to (i) fund a portion of the cash consideration in connection with the Argos USA closing (see note 20), (ii) refinance the 
$504.5 million of existing term loans outstanding and (iii) pay fees, commissions and expenses in connection with the 
foregoing;

(2) in respect of the revolving credit facility thereunder (the “Revolving Credit Facility”), (a) increase the total 

aggregate commitments under the Revolving Credit Facility from $395.0 million to $625.0 million and (b) reduce the 
applicable margin (with no leverage-based step downs) to (i) 1.50% per annum with respect to base rate borrowings and a floor 
of 1.00% per annum or (ii) 2.50% per annum with respect to Term SOFR borrowings and a floor of zero; and

(3) modify certain covenants to provide greater flexibility for Summit LLC under the Credit Agreement.

On January 10, 2023, Summit Materials, LLC entered into Amendment No. 6 to the Credit Agreement, which among 
other things, increased the maximum amount available under the Revolving Credit Facility to $395.0 million and extended the 
maturity date to January 10, 2028.

On December 14, 2022, Summit Materials, LLC entered into Amendment No. 5 to the Credit Agreement, which 

among other things, (a) refinanced the existing $509.6 million of existing term loans with new term loans under the Term Loan 
Facility and extended the maturity date to December 14, 2027.

As of December 30, 2023, the Term Loan Facility bears interest per annum equal to, at Summit LLC’s option, either 

(i) a base rate determined by reference to the highest of (a) the federal funds rate plus 0.50%, (b) the prime rate of Bank of 
America, N.A. and (c) Term SOFR plus 1.00%, plus an applicable margin of 2.00% per annum for base rate loans or (ii) Term 
SOFR plus an applicable margin of 3.00% per annum for Term SOFR rate loans. The revolving credit facility matures on 
January 10, 2028, provided that if more than $125 million of the 2027 Notes are outstanding as of December 14, 2026, then the 
maturity date of the revolving credit facility will be December 14, 2026.

There were no outstanding borrowings under the Revolving Credit Facility as of December 30, 2023 or December 31, 

2022. As of December 30, 2023, we had remaining borrowing capacity of $374.1 million under the revolving credit facility, 

84

 
 
which is net of $20.9 million of outstanding letters of credit. The outstanding letters of credit are renewed annually and support 
required bonding on construction projects and the Company’s insurance liabilities.

Summit LLC’s Consolidated First Lien Net Leverage Ratio, as such term is defined in the Credit Agreement, should 

be no greater than 4.75:1.0 as of each quarter-end. As of December 30, 2023 and December 31, 2022, Summit LLC was in 
compliance with all financial covenants under the Credit Agreement.

Summit LLC’s wholly-owned domestic subsidiary companies, subject to certain exclusions and exceptions, are named 

as subsidiary guarantors of the Senior Notes and the Senior Secured Credit Facilities. In addition, Summit LLC has pledged 
substantially all of its assets as collateral, except for real property and subject to certain exclusions and exceptions, for the 
Senior Secured Credit Facilities.

(9) Income Taxes

Summit Inc.’s tax provision includes its proportional share of Summit Holdings’ tax attributes. Summit Holdings’ 

subsidiaries are primarily limited liability companies, but do include certain entities organized as C corporations and a Canadian 
subsidiary. The tax attributes related to the limited liability companies are passed on to Summit Holdings and then to its 
partners, including Summit Inc. The tax attributes associated with the C corporation and Canadian subsidiaries are fully 
reflected in the Company’s consolidated financial statements. For the years ended December 30, 2023, December 31, 2022 and 
January 1, 2022, income taxes consisted of the following:

As of December 30, 2023, $318.1 million of our deferred tax assets subject to our TRA are included in the net 

intangible assets and the net operating loss line items above. 

Our income tax expense (benefit) was $104.8 million, $85.5 million and $44.4 million in the fiscal years ended 2023, 
2022 and 2021, respectively. Our effective income tax rate in 2021 was impacted by the IRS interpretative guidance of the Tax 
Cuts and Jobs Act (the “TCJA”), a change in state tax rates and a change in the amount of our TRA liability.

The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the 
periods in which those temporary differences become deductible, as well as consideration of tax-planning strategies we may 
seek to utilize net operating loss carryforwards that begin to expire in 2030. The Company updates the analysis, and adjusted 
the valuation allowance for interest expense carryforwards limited under the TCJA based on updated forecast models each year.

We had no unrecognized tax benefits as of December 30, 2023 and December 31, 2022, respectively. We did not 

recognize interest or penalties related to this amount as it is offset by other attributes.

Our net operating loss carryforward deferred tax assets begin to expire in 2030 and are expected to reverse before 
expiration. Therefore, we have not given consideration to any potential tax planning strategies as a source of future taxable 
income to monetize those net operating loss carryforwards. The Company will continue to monitor facts and circumstances, 
including our analysis of other sources of taxable income, in the reassessment of the likelihood that the tax benefit of our 
deferred tax assets will be realized.

As of December 30, 2023, Summit Inc. had federal net operating loss carryforwards of $818.0 million, a portion of 

which expire between 2030 and 2038. As of December 30, 2023, $761.0 million of our federal net operating losses were under 
the terms of our TRA. As of December 30, 2023 and December 31, 2022, Summit Inc. had a valuation allowance on net

likely than not.

Tax Receivable Agreement— During 2015, the Company entered into a TRA with the holders of LP Units and certain 

other pre-initial public offering owners that provides for the payment by Summit Inc. to exchanging holders of LP Units of 85% 
of the benefits, if any, that Summit Inc. actually realizes (or, under certain circumstances such as an early termination of the 
TRA, is deemed to realize) as a result of increases in the tax basis of tangible and intangible assets of Summit Holdings and 
certain other tax benefits related to entering into the TRA, including tax benefits attributable to payments under the TRA.

When LP Units are exchanged for an equal number of newly-issued shares of Summit Inc.’s Class A common stock, 

these exchanges result in new deferred tax assets. Using tax rates in effect as of each year end, $5.4 million and $0.3 million of 
deferred tax assets were created during the years ended December 30, 2023 and December 31, 2022, respectively, when LP 
Units were exchanged for shares of Class A common stock.

In the year ended December 30, 2023, 548,761 LP Units were acquired by Summit Inc. in exchange for an equal 

number of newly-issued shares of Summit Inc.’s Class A common stock. Additionally, Summit LLC reached an agreement to 
acquire all of the rights and interests in the TRA from affiliates of Blackstone Inc. and certain other TRA holders for aggregate 
cash consideration of $132.5 million. In connection with these transactions, Summit LLC and Summit Inc. reached an 
agreement whereby the maximum amount Summit Inc. is obligated to pay Summit LLC for the TRA interests acquired is 
limited to the amount Summit LLC paid for the TRA interests. As the cash paid for TRA interests acquired was less than their 
carrying value, Summit Inc. recognized a tax receivable agreement benefit of $157.5 million in the accompanying consolidated 
statement of operations.

Each year, we update our estimate as to when TRA payments will be made. The timing and cash tax savings of those 

payments can cause variations in the future value of TRA tax attributes. As noted above, when payments are made under the 
TRA, a portion of the payment made will be characterized as imputed interest under IRS regulations. We also updated our 
estimate of the state income tax rate that will be in effect at the date the TRA payments are made. As a result of our updated 
state income tax rate, and the variance in TRA tax attributes noted above, we have decreased our TRA liability by $4.7 million 
and increased by $1.3 million as of December 30, 2023 and December 31, 2022, respectively. 

Our TRA liability as of December 30, 2023 and December 31, 2022 was $41.7 million and $327.8 million, 

respectively.

Changes in the balance of the TRA liability, from December 31, 2022 to December 30, 2023 are summarized as

Tax Distributions – The holders of Summit Holdings’ LP Units, including Summit Inc., incur U.S. federal, state and 

local income taxes on their share of any taxable income of Summit Holdings. The limited partnership agreement of

87

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Summit Holdings provides for pro rata cash distributions (“tax distributions”) to the holders of the LP Units in an amount 
generally calculated to provide each holder of LP Units with sufficient cash to cover its tax liability in respect of the LP Units. 
In general, these tax distributions are computed based on Summit Holdings’ estimated taxable income allocated to Summit Inc. 
multiplied by an assumed tax rate equal to the highest effective marginal combined U.S. federal, state and local income tax rate 
applicable to a corporate resident in New York, New York.

For the years ended December 30, 2023 and December 31, 2022, Summit Holdings paid tax distributions totaling 

$0.5 million and $0.7 million, respectively, to holders of its LP Units, other than Summit Inc. 

C Corporation Subsidiaries — The effective income tax rate for the C corporations differ from the statutory federal 
rate primarily due to (1) tax depletion expense (benefit) in excess of the expense recorded under U.S. GAAP, (2) state income 
taxes and the effect of graduated tax rates, (3) differences between book and tax basis for divested businesses, (4) various other 
items such as limitations on meals and entertainment and other costs and (5) unrecognized tax benefits. The effective income 
tax rate for the Canadian subsidiary is not significantly different from its historical effective tax rate.

No material interest or penalties were recognized in income tax expense during the years ended December 30, 2023, 
December 31, 2022 or January 1, 2022. Tax years from 2015 to 2019 remain open and subject to audit by federal, Canadian, 
and state tax authorities.

(10) Earnings Per Share

Basic earnings per share is computed by dividing net earnings by the weighted average common shares outstanding 

and diluted net earnings is computed by dividing net earnings, adjusted for changes in the earnings allocated to Summit Inc. as 
a result of the assumed conversion of LP Units, by the weighted-average common shares outstanding assuming dilution.

(13) Stock-Based Compensation

Prior to the IPO and related Reorganization, the capital structure of Summit Holdings consisted of six different classes 
of limited partnership units, each of which was subject to unique distribution rights. In connection with the IPO and the related 
Reorganization, the limited partnership agreement of Summit Holdings was amended and restated to, among other things, 
modify its capital structure by creating LP Units. Holders of the LP Units periodically exchange their LP Units for shares of 
Class A common Stock of Summit Inc.

Omnibus Incentive Plan

Our 2015 Omnibus Incentive Plan (the "Plan") allows for grants of equity-based awards in the form of stock options, 

stock appreciation rights, restricted stock, restricted stock units, performance units and other stock-based awards. The Plan 
authorizes the issuance of up to 17,500,000 shares of Class A common stock in the form of restricted stock units and stock 
options, of which 6.4 million shares of Class A common stock were available for future grants as of December 30, 2023.

Employee Stock Purchase Plan

At the May 2021 Annual Meeting, stockholders approved the Summit Materials, Inc. 2021 Employee Stock Purchase 

Plan (the “ESPP”), which authorized 5,500,000 shares of Class A common stock for issuance under the ESPP. All eligible 
employees may voluntarily enroll to purchase the Company’s Class A common stock through payroll deductions at a price 
equal to 85% of the lower of the fair market values of the stock as of the beginning or the end of six-month offering periods. 
Compensation expense is measured as the discount the employee is entitled to upon purchase and is recognized over the 
offering period. As of December 30, 2023, 5.5 million shares of Class A common stock were reserved for future issuance 
through the ESPP, with 5.3 million shares available for issuance.

Restricted Stock

Restricted Stock with Service-Based Vesting—Under the Plan, the Compensation Committee of the Board of Directors 

(the “Compensation Committee”) has granted restricted stock to members of the Board of Directors, executive officers and 
other key employees. These awards contain service conditions associated with continued employment or service. The terms of 
the restricted stock provide voting and regular dividend rights to holders of the awards. Upon vesting, the restrictions on the 
restricted stock lapse and the shares are considered issued and outstanding for accounting purposes.

In each of 2023, 2022 and 2021, the Compensation Committee granted restricted stock to executives and key 

employees under the Plan as part of our annual equity award program, which vest over a one to three year period, subject to 
continued employment or service. From time to time, the Compensation Committee grants restricted stock to newly hired or 
promoted employees or other employees who have achieved extraordinary personal performance objectives.

Further, in each of 2023, 2022 and 2021, the Compensation Committee granted 32,304, 30,520 and 34,672 shares, 

respectively, to non-employee members of the Board of Directors for their annual service as directors. These restricted stock 
grants vest over a one year period.

In measuring compensation expense associated with the grant of restricted stock, we use the fair value of the award, 
determined as the closing stock price for our Class A common stock on the date of grant. Compensation expense is recorded 
monthly over the vesting period of the award.

Restricted stock with Service, Market-Condition-Based and Performance Based Vesting—In 2023, 2022 and 2021, the 

Compensation Committee granted restricted stock to certain members of our executive team as part of their annual 
compensation package. The restricted stock vests at the end of a three year performance period, based on our total stock return 
(“TSR”) ranking relative to companies in the S&P Building & Construction Select Industry Index, as well as increases in our 
return on invested capital, subject to continued employment.

Compensation expense is recorded monthly over the vesting period of the awards. The following table summarizes

The fair value of the time-vesting options granted was estimated as of the grant date using the Black-Scholes-Merton 
model, which requires the input of subjective assumptions, including the expected volatility and the expected term. No options 
to purchase common stock were granted in 2023, 2022 and 2021. The fair value of the performance stock units granted was 
estimated as of the grant date using Monte Carlo simulations, which requires the input of subjective assumptions, including the 
expected volatility and the expected term.

The risk-free rate is based on the yield at the date of grant of a U.S. Treasury security with a maturity period 

approximating the expected term. As Summit Holdings has not historically and does not plan to issue regular dividends, a 
dividend yield of zero was used. The volatility assumption is based on reported data of a peer group of publicly traded 
companies for which historical information was available adjusted for the Company’s capital structure. The expected term is 
based on expectations about future exercises and represents the period of time that the units granted are expected to be 
outstanding.

Compensation expense for time-vesting interests granted is based on the grant date fair value. The Company 

recognizes compensation costs on a straight-line basis over the service period, which is generally the vesting period of the 
award. Forfeitures are recognized as they occur. Share-based compensation expense, which is recognized in general and 
administrative expenses, totaled $20.3 million, $18.3 million and $19.7 million in the years ended December 30, 2023, 
December 31, 2022 and January 1, 2022, respectively. As of December 30, 2023, unrecognized compensation cost totaled $23.0

million. The weighted average remaining contractual term over which the unrecognized compensation cost is to be recognized 
is 1.8 years as of year-end 2023.

As of December 30, 2023, the intrinsic value of outstanding options, restricted stock units and performance stock units 
was $5.0 million, $41.2 million and $16.7 million, respectively, and the remaining contractual term was 1.8 years, 0.9 years and 
1.3 years, respectively. The weighted average strike price of 0.3 million exercisable stock options outstanding as of December 
30, 2023 was $19.70 per share. 

(14) Employee Benefit Plans

Defined Contribution Plan—The Company sponsors employee 401(k) savings plans for its employees, including 

certain union employees. The plans provide for various required and discretionary Company matches of employees’ eligible 
compensation contributed to the plans. The expense for the defined contribution plans was $15.3 million, $12.1 million and 
$10.9 million for the years ended December 30, 2023, December 31, 2022 and January 1, 2022, respectively.

Defined Benefit and Other Postretirement Benefits Plans—The Company’s subsidiary, Continental Cement, sponsors 
two noncontributory defined benefit pension plans for hourly and salaried employees. The plans are closed to new participants 
and benefits are frozen. Pension benefits for eligible hourly employees are based on a monthly pension factor for each year of 
credited service. Pension benefits for eligible salaried employees are generally based on years of service and average eligible 
compensation. Continental Cement also sponsors two unfunded healthcare and life insurance benefits plans for certain eligible 
retired employees. 

The funded status of the pension and other postretirement benefit plans is recognized in the consolidated balance 

sheets as the difference between the fair value of plan assets and the benefit obligations. For defined benefit pension plans, the 
benefit obligation is the projected benefit obligation (“PBO”) and for the healthcare and life insurance benefits plans, the benefit 
obligation is the accumulated postretirement benefit obligation (“APBO”). The PBO represents the actuarial present value of 
benefits expected to be paid upon retirement based on estimated future compensation levels. However, since the plans’ 
participants are not subject to future compensation increases, the plans’ PBO equals the accumulated benefit obligation 
(“ABO”). The APBO represents the actuarial present value of postretirement benefits attributed to employee services already 
rendered. The fair value of plan assets represents the current market value of assets held by an irrevocable trust fund for the sole 
benefit of participants. The measurement of the benefit obligations is based on the Company’s estimates and actuarial 
valuations. These valuations reflect the terms of the plan and use participant-specific information, such as compensation, age 
and years of service, as well as certain assumptions that require significant judgment, including estimates of discount rates, 
expected return on plan assets and mortality rates.

The Company uses December 31 as the measurement date for its defined benefit pension and other postretirement 

benefit plans.

Obligations and Funded Status—The following information is as of December 30, 2023 and December 31, 2022 and

Discount rate
Expected long-term 
rate of return on 
plan assets

The expected long-term return on plan assets is based upon the Plans’ consideration of historical and forward-looking 
returns and the Company’s estimation of what a portfolio, with the target allocation described below, will earn over a long-term 
horizon. The discount rate is derived using the FTSE Above Median Pension Discount Curve.

The assumed health care cost trend rate for year end 2023 was 6.75% grading to 4.46% in 2042. As of year end 2022, 
the assumed trend rate was 7.00% grading to 4.46% in 2032. Assumed health care cost trend rates have a significant effect on 
the amounts reported for the Company’s healthcare and life insurance benefits plans.

Plan Assets—The defined benefit pension plans’ (the “Plans”) investment strategy is to minimize investment risk 

while generating acceptable returns. The Plans currently invest a relatively high proportion of the plan assets in fixed income 
securities, while the remainder is invested in equity securities, cash reserves and precious metals. The equity securities are 
diversified into funds with growth and value investment strategies. The target allocation for plan assets is as follows: equity 
securities—35%; fixed income securities—55%; cash reserves—5%; alternatives—4%; and precious metals—1%. The Plans’ 
current investment allocations are within the tolerance of the target allocation. The Company had no Level 3 investments as of 
or for the years ended December 30, 2023 and December 31, 2022.

At year-end 2023 and 2022, the Plans’ assets were invested predominantly in fixed-income securities and publicly 

traded equities, but may be invested in other asset classes in the future subject to the parameters of the investment policy. The 
Plans’ investments in fixed-income assets include U.S. Treasury and U.S. agency securities and corporate bonds. The Plans’ 
investments in equity assets include U.S. and international securities and equity funds. The Company estimates the fair value of 
the Plans’ assets using various valuation techniques and, to the extent available, quoted market prices in active markets or 
observable market inputs. The descriptions and fair value methodologies for the Plans’ assets are as follows:

Fixed Income Securities—Corporate and government bonds are classified as Level 2 assets, as they are either valued at 

quoted market prices from observable pricing sources at the reporting date or valued based upon comparable securities with 
similar yields and credit ratings.

Equity Securities—Equity securities are valued at the closing market price reported on a U.S. exchange where the 

security is actively traded and are therefore classified as Level 1 assets.

Cash—The carrying amounts of cash approximate fair value due to the short-term maturity.

Precious Metals—Precious metals are valued at the closing market price reported on a U.S. exchange where the 

security is actively traded and are therefore classified as Level 1 assets.

The fair value of the Plans’ assets by asset class and fair value hierarchy level as of December 30, 2023 and December 

31, 2022 are as follows:

Multiemployer Pension Plans— In 2018, through an acquisition, the Company assumed an obligation to contribute to 

a number of multiemployer defined benefit pension plans under the terms of collective-bargaining agreements that cover its 
union-represented employees. The risks of participating in multiemployer pension plans are different from single-employer 
plans. Assets contributed to a multiemployer plan by one employer may be used to provide benefits to employees of other 
participating employers. If a participating employer ceases contributing to the plan, the unfunded obligations of the plan are the 
responsibility of the remaining participating employers.

The Company's participation in these plans for the annual period ended December 31, 2023, is outlined in the table 
below. The ''EIN/Pension Plan Number" column provides the Employer Identification Number (EIN) and the three-digit plan 
number, if applicable. Unless otherwise noted, the most recent Pension Protection Act (PPA) zone status available in 2023 and 
2022 is for the plan 's year end at December 31, 2023, and December 31, 2022, respectively. The zone status is based on 
information the Company received from the plan and is certified by the plan's actuary. Among other factors, plans in the red

(15) Accrued Mining and Landfill Reclamation

The Company has asset retirement obligations arising from regulatory or contractual requirements to perform certain 
reclamation activities at the time that certain quarries and landfills are closed, which are primarily included in other noncurrent 
liabilities on the consolidated balance sheets. The current portion of the liabilities, $5.1 million and $4.0 million as of December 
30, 2023 and December 31, 2022, respectively, is included in accrued expenses on the consolidated balance sheets. The total 
undiscounted anticipated costs for site reclamation as of December 30, 2023 and December 31, 2022 were $141.8 million and 
$124.9 million, respectively. The liabilities were initially measured at fair value and are subsequently adjusted for accretion 
expense, payments and changes in the amount or timing of the estimated cash flows. The corresponding asset retirement costs 
are capitalized as part of the carrying amount of the related long-lived asset and depreciated over the asset’s remaining useful 
life. The following table presents the activity for the asset retirement obligations for the years ended December 30, 2023 and 
December 31, 2022:

The Company is party to certain legal actions arising from the ordinary course of business activities. Accruals are 
recorded when the outcome is probable and can be reasonably estimated. While the ultimate results of claims and litigation 
cannot be predicted with certainty, management expects that the ultimate resolution of all current pending or threatened claims 
and litigation will not have a material effect on the Company’s consolidated financial position, results of operations or liquidity. 
The Company records legal fees as incurred.

In March 2018, we were notified of an investigation by the Canadian Competition Bureau (the “CCB”) into pricing 

practices by certain asphalt paving contractors in British Columbia, including Winvan Paving, Ltd. (“Winvan”). The 
investigation is focused on time periods prior to our April 2017 acquisition of Winvan and we are cooperating with the CCB. 
Although we currently do not believe this matter will have a material adverse effect on our business, financial condition or 
results of operations, we are currently not able to predict the ultimate outcome or cost of the investigation.

Environmental Remediation and Site Restoration—The Company’s operations are subject to and affected by federal, 

state, provincial and local laws and regulations relating to the environment, health and safety and other regulatory matters. 
These operations require environmental operating permits, which are subject to modification, renewal and revocation. The 
Company regularly monitors and reviews its operations, procedures and policies for compliance with these laws and 
regulations. Despite these compliance efforts, risk of environmental liability is inherent in the operation of the Company’s 
business, as it is with other companies engaged in similar businesses and there can be no assurance that environmental liabilities 
or noncompliance will not have a material adverse effect on the Company’s consolidated financial condition, results of 
operations or liquidity.

Other—The Company is obligated under various firm purchase commitments for certain raw materials and services 
that are in the ordinary course of business. Management does not expect any significant changes in the market value of these 
goods and services during the commitment period that would have a material adverse effect on the financial condition, results 
of operations and cash flows of the Company. The terms of the purchase commitments generally approximate one year.

(17) Leases

We lease construction and office equipment, distribution facilities and office space. Leases with an initial term of 12 
months or less, including month to month leases, are not recorded on the balance sheet. Lease expense for short-term leases is 
recognized on a straight line basis over the lease term. For lease agreements we have entered into or reassessed, we combine 
lease and nonlease components. While we also own mineral leases for mining operations, those leases are outside the scope of 
ASU No. 2016-2, Leases (Topic 842). Assets acquired under finance leases are included in property, plant and equipment.

Many of our leases include options to purchase the leased equipment. The depreciable life of assets and leasehold 

improvements are limited by the expected lease term, unless there is a transfer of title or purchase option reasonably certain of 
exercise. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants. The 
components of lease expense were as follows:

The Company has lease agreements associated with quarry facilities under which royalty payments are made. The 

payments are generally based on tons sold in a particular period; however, certain agreements have minimum annual payments. 
Royalty expense recorded in cost of revenue during the years ended December 30, 2023, December 31, 2022 and January 1, 
2022 was $35.8 million, $33.5 million and $34.8 million, respectively. Minimum contractual commitments for the subsequent

(18) Fair Value of Financial Instruments

Fair Value Measurements—Certain acquisitions made by the Company require the payment of contingent amounts 
of purchase consideration. These payments are contingent on specified operating results being achieved in periods subsequent 
to the acquisition and will only be made if earn-out thresholds are achieved. Contingent consideration obligations are measured 
at fair value each reporting period. Any adjustments to fair value are recognized in earnings in the period identified.

The fair value of contingent consideration as of December 30, 2023 and December 31, 2022 was: 

Current portion of acquisition-related liabilities and Accrued expenses:

Contingent consideration

Acquisition-related liabilities and Other noncurrent liabilities:

Contingent consideration

The fair value accounting guidance establishes the following fair value hierarchy that prioritizes the inputs used to 

measure fair value:

Level  1 —  Quoted prices in active markets for identical assets and liabilities.
Level 2 —  Observable inputs, other than quoted prices, for similar assets or liabilities in active markets.
Level 3 —  Unobservable inputs, which includes the use of valuation models.

Financial Instruments—The Company’s financial instruments include debt and certain acquisition-related liabilities 

(deferred consideration and noncompete obligations). The carrying value and fair value of these financial instruments as of 
December 30, 2023 and December 31, 2022 were:

Level 1 fair values are used to value investments in publicly-traded entities and assumed obligations for publicly-

traded long-term debt.

Level 2 fair values are typically used to value acquired receivables, inventories, machinery and equipment, land, 

buildings, deferred income tax assets and liabilities, liabilities for asset retirement obligations, environmental remediation and 
compliance obligations. Additionally, Level 2 fair values are typically used to value assumed contracts at other-than-market 
rates. 

Level 3 fair values are used to value acquired mineral reserves and leased mineral interests and other identifiable 
intangible assets. The fair values of mineral reserves and leased mineral interests are determined using an excess earnings 
approach, which requires management to estimate future cash flows. The estimate of future cash flows is based on available 
historical information and forecasts determined by management, but is inherently uncertain. Key assumptions in estimating 
future cash flows include sales price, volumes and expected profit margins, net of capital requirements. The present value of the 
projected net cash flows represents the fair value assigned to mineral reserves and mineral interests. The discount rate is a 
significant assumption used in the valuation model and is based on the required rate of return that a hypothetical market 
participant would assume if purchasing the acquired business.

The Level 3 fair values of contingent consideration were based on projected probability-weighted cash payments and a 

10.0% discount rate, which reflects a market discount rate. Changes in fair value may occur as a result of a change in actual or 
projected cash payments, the probability weightings applied by the Company to projected payments or a change in the discount 
rate. Significant increases or decreases in any of these inputs in isolation could result in a lower, or higher, fair value 
measurement. There were no material adjustments to the fair value of contingent consideration in 2023 or 2022. The fair values 
of the deferred consideration and noncompete obligations were determined based on the cash payment terms in the purchase 
agreements and a discount rate reflecting the Company’s credit risk. The discount rate used is generally consistent with that 
used when the obligations were initially recorded.

Securities with a maturity of three months or less are considered cash equivalents and the fair value of these assets 

approximates their carrying value.

(19) Segment Information

The Company has three operating segments: West, East and Cement, which are its reporting segments. These segments 

are consistent with the Company’s management reporting structure. The operating results of each segment are regularly 
reviewed and evaluated by the Chief Executive Officer, the Company’s Chief Operating Decision Maker (“CODM”). The 
CODM primarily evaluates the performance of the Company's segments and allocates resources to them based on a segment 
profit metric that we call Adjusted EBITDA, which is computed as earnings from continuing operations before interest, taxes, 
depreciation, depletion, amortization, accretion, share-based compensation, and transaction costs, as well as various other non-
recurring, non-cash amounts.

The West and East segments have several acquired subsidiaries that are engaged in various activities including quarry 

mining, aggregate production and contracting. The Cement segment is engaged in the production of Portland cement. Assets 
employed by each segment include assets directly identified with those operations. Corporate assets consist primarily of cash, 
property, plant and equipment for corporate operations and other assets not directly identifiable with a reportable business 
segment. The accounting policies applicable to each segment are consistent with those used in the consolidated financial 
statements.

The following tables display selected financial data for the Company’s reportable business segments as of and for the 

years ended December 30, 2023, December 31, 2022 and January 1, 2022:

In January 2024, Summit completed a merger with Argos North America Corporation ("Argos USA"), Cementos 

Argos S.A., Argos SEM LLC and Valle Cement Investments, Inc., pursuant to which Summit acquired all of the outstanding 
equity interests (the "Transaction") of Argos USA from the Argos SEM LLC and Valle Cement Investments, Inc. in exchange 
for $1.2 billion of cash, the issuance of 54,720,000 shares of the Company's Class A common stock and one preferred share in a 
transaction valued at approximately $3.2 billion. The cash consideration was funded from the net proceeds of an $800 million 
offering of Senior Notes due 2031 and new term loan borrowings under our current credit facility. The purchase price is subject 
to customary adjustments, with any upward or downward adjustments made against the cash consideration. The Transaction 
Agreement, dated as of September 7, 2023, contains customary representations and warranties, covenants and agreements, 
including a Stockholder Agreement. 

The Argos USA assets include four integrated cement plants, two grinding facilities, 140 ready-mix concrete plants, 
eight ports and 10 inland terminals across the East and Gulf Coast regions, with a total installed cement grinding capacity of 
9.6 million tons per annum and a total import capacity of 5.4 million tons of cement per annum. The import facilities allow the 
importing of cement from other countries, including a minimum quantity from a cement plant in Cartagena, Colombia, owned 
by Cementos Argos S.A., as stipulated under a cement supply agreement entered into upon the closing of the Transaction. The 
Argos USA assets included 1.2 billion tons of reserves and resources in four quarries.

The following unaudited pro forma financial information summarizes the results of operations for the Company and 
Argos USA as though the companies merged as of January 1, 2022. Financial information for 2023 does not reflect any cost 
savings or associated costs to achieve such savings from operating efficiencies or synergies that may result from the merger. 
However, we have reflected elimination of royalties expenses paid to the parent of Argos USA which will not be incurred post 
merger. We have also adjusted for expenses incurred by Argos USA as they pursed an initial public offering and the merger 
with the Company, as well as interest expense adjustments to reflect the payoff of Argos USA debt obligations and new debt 
issued by the Company described above.

Management’s Report on Internal Control Over Financial Reporting

The Stockholders of Summit Materials, Inc.:

The management of Summit Materials, Inc. and Summit Materials, LLC is responsible for establishing and maintaining 
adequate internal control over financial reporting and for its assessment of the effectiveness of internal control over financial 
reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. Our internal control system was designed to 
provide reasonable assurance to our management and board of directors regarding the preparation and fair presentation of 
published financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, 
projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate 
because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Our management evaluated the effectiveness of our internal control over financial reporting as of December 30, 2023. In 
making this evaluation, we used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway 
Commission (COSO) in Internal Control – Integrated Framework (2013). Based on our evaluation we believe that, as of 
December 30, 2023 our internal control over financial reporting is effective based on those criteria.

KPMG LLP has issued an audit report on the effectiveness of Summit Materials, Inc.’s internal control over financial reporting. 
The KPMG LLP report immediately follows this report. This annual report does not include an attestation report of Summit 
Materials, LLC’s independent registered public accounting firm regarding internal control over financial reporting. 
Management’s report was not subject to attestation by Summit Materials, LLC’s registered public accounting firm pursuant to 
rules of the Securities and Exchange Commission applicable to “non-accelerated filers.”

Report of Independent Registered Public Accounting Firm

To the Stockholders and Board of Directors
Summit Materials, Inc.:

Opinion on Internal Control Over Financial Reporting

We have audited Summit Materials, Inc. and subsidiaries' (the Company) internal control over financial reporting as of 
December 30, 2023, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee 
of Sponsoring Organizations of the Treadway Commission. In our opinion, the Company maintained, in all material respects, 
effective internal control over financial reporting as of December 30, 2023, based on criteria established in Internal Control – 
Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) 
(PCAOB), the consolidated balance sheets of the Company as of December 30, 2023 and December 31, 2022, the related 
consolidated statements of operations, comprehensive income, cash flows and changes in stockholders’ equity for each of the 
fiscal years in the three-year period ended December 30, 2023, and the related notes (collectively, the consolidated financial 
statements), and our report dated February 15, 2024 expressed an unqualified opinion on those consolidated financial 
statements.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its 
assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Report 
on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control 
over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be 
independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and 
regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the 
audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all 
material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control 
over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating 
effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we 
considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the 
reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally 
accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures 
that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and 
dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit 
preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and 
expenditures of the company are being made only in accordance with authorizations of management and directors of the 
company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or 
disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, 
projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate 
because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
