OUR VISION

Across North America, we are deeply rooted in our communities,
dedicated to being responsible stewards of the environment,
and focused on programs to build and engage our employees.
Our sustainability program strives to focus on the most
material topics to our stakeholders, implemented in unique
ways in every company and community where we operate.
We believe that with continued involvement of our employees,
and the completion of each action, Summit becomes a better
company. By tirelessly and consistently working towards a more
sustainable Summit, we are ensuring profitability and building a
company that will thrive for generations to come. The following
pages and programs represent the progress and initiatives that
we have undertaken in 2018 to deliver long-term value to our
stakeholders.

EMPLOYEES

Our employees are the backbone of our business and we are
proud to stand behind them. This section details the many
programs that we have at Summit Materials to support our
employees and their work:

• Safety
• Employee Wellness
• Recruiting and Training
• Employee Engagement

Our employees’ commitment to safety and getting the job
done is the foundation of our company, which is why we work
hard every day to support them in their jobs. We consider
health and safety top priorities. With on-the-job training
and leadership development opportunities, it’s important
to us to help grow our employees’ respective careers. And
for those who’ve spent their entire careers dedicated to the
company, we thank them for their years of incredible service
and hard work.

We proudly stand behind our people, who represent a
diverse family of companies and the employees that make
us who we are.

11

SAFETY

Safety is a way of life. It is how we begin and end each day. We are disciplined in
our approach and aim for a world-class safety program. Across all of our business
lines, functions, and companies, we consistently work hard to deliver on that goal.

We use workplace organization tools like 5S (sort, simplify, shine, standardize,
sustain) to ensure that issues like housekeeping and storage don’t present safety
hazards like slips, trips, and falls.

Risk assessments and our 10 safety principles give us a framework for decision
making, helping to ensure that all tasks are carried out with safety first in mind. We
hold weekly safety meetings, tool box talks, and regular trainings to keep ideas fresh
and to develop a culture where safety is everyone’s job.

Our Journey to Zero campaign is about educating and encouraging our employees
to keep safety top of mind. We share weekly safety stats with employees across all
companies, challenge each other with site 5S initiatives, and welcome new ideas
with Safety Leadership Teams from each company. It’s a consistent drum beat
across all lines of business, in all locations, and we are proud of our results.

5S: SAFETY IN STANDARDIZATION

Sort, simplify, shine, standardize, sustain. In recent years we have begun a
very impactful 5S campaign. This is about keeping workplaces, vehicles, offices,
and all locations tidy and organized. This is no small task when hundreds
of vehicles and employees are in and out every day with heavy equipment,
shops, and PPE (personal protective equipment). These images speak louder
than words and show that our commitment to safety goes beyond the
numbers. We believe that little things like organization and tidiness can have
a big impact on safer job sites and reduced injuries.

DIVERSITY AND INCLUSION

At Summit we seek to build our company as a broadly diverse and equal
opportunity place of employment for people of all genders, race, ethnicity, age,
and abilities. We aim to reflect this effort across our company from boots on the
ground to our Board of Directors.
Our operating company Cornejo & Sons, based in Wichita, Kansas, was named a
Leader in Diversity by the Wichita Business Journal for their inclusive and equal-
opportunity employment initiatives. The women pictured here represent an
exceptional team of employees who are helping us work toward advancing
women in construction.
The advancement of diversity is vital to the identity of Summit and the future of the
construction industry. We are proud to include each and every one of our people
in the Summit family, where respect, humility and ideas are valued from every
individual.

Summit and our operating companies have formed partnerships with some
of the top mining universities in the country. Our internship program helps
us identify bright, young talent, and provides young professionals with an
opportunity to learn and deploy new skills in an experienced supervised
setting. In 2018 we started a corporate intern training program, “Summit
INCLINE” (Internship Collaborative LearnINg Experience), bringing students to
our corporate headquarters in Denver for a multi-day training. The program
is designed to provide a meaningful learning experience on Summit, our
culture and values, our industry, and personal career development. Working
with the next generation of employees and gaining perspective in new talent
is an important part of our company’s succession plans. Students reported
that this event helped expand their horizons and offered incredible learning
opportunities.

ENVIRONMENT

Our environmental program starts with stewardship of our
land and resources, and is guided by the company wide
commitments laid out in our public environmental policy.

We work hard to look for new ways to reduce energy use, water
use, and waste creation. This is something that we are focused
on in each line of business at all of our companies. With some
proud achievements this year, our companies and employees
are more engaged than ever on reducing our impact on the
environment and restoring land value through rehabilitation
projects that improve biodiversity. This section includes
information on programs and projects we’ve implemented in
each line of business to reduce our environmental impact and
showcase our risk mitigation strategies advancing this effort.

strict energy performance levels set by the EPA. https://www.eia.gov/tools/faqs/faq.php?id=97&t=3

In 2018, our cement plants averaged more than 43% of their total energy derived
from alternative fuels. Our Hannibal plant co-processes both liquid and solid
hazardous waste as a fuel source, which would otherwise be incinerated. The
Davenport Cement Plant uses alternative fuels from surrounding industrial
factories, including items like off-spec seeds, byproducts from toothbrush
manufacturing, used tires and other materials that would otherwise be landfilled.

MAINLAND FLAGSHIP QUARRY 12%APPROXIMATELY
REDUCTION
OUTSIDE OF VANCOUVER, BRITISH COLUMBIA INSTALLS NEW IN ENERGY USED PER TON
PLANT TO INCREASE PRODUCTION AND REDUCE ENERGY.

In late 2018, Cox Quarry came online with a new crushing plant. This
upgrade can triple production output per hour and has demonstrated
important upgrades to operations from an energy and environmental
standpoint. Based on the initial figures in six months of operation, the
new plant has decreased electrical consumption per ton produced in
comparison to prior years by an average of 12%. In addition, BC Hydro
Utility estimates that more than 90%* of their supplied energy is obtained
from hydroelectric energy, making this the least carbon intensive quarry
across our portfolio.

Another benefit to the new plant is that the location of the crusher is
nearly a mile closer to the mining face. This distance has decreased the
area fleet from five to three trucks, reducing fuel use, emissions, and road
dust, all from less truck traffic.

This flagship example showcases a high level commitment to ensuring
that our capital expenditures are helping to create energy efficiencies
along with production improvements.

THERMOGRAPHY TOOL
IN ENERGY MANAGEMENT

Thermography is an infrared technology we are using at our
aggregate plants that allows us to more effectively manage our
equipment, downtime, and subsequent energy use. This technology
is another tool we are using in our smart energy campaign.

The infrared photos enable us to better see electrical components
that may not be functioning properly and, in turn, fix the issue
before it becomes a bigger problem with unnecessary downtime.
Electrical components that aren’t functioning properly can produce
energy leaks and the impact of reducing these leaks across the
majority of our aggregate locations is substantial.

We estimate that 75% of our aggregate plants are using this
technology on an annual basis and the results have helped us
to become more energy efficient. Since adopting this tool, our
facilities are experiencing less downtime, which means more
production, and smarter use of energy.

75%APPROXIMATELY OF OUR AGGREGATE
PLANTS ARE USING
THERMOGRAPHY

TRANSPORTING MATERIALS

We now have ten John Deere 944K Hybrid loaders operating at full
steam at our busiest quarries across the country. Our drivers report
that these vehicles are not only fun to drive, but help us reduce
fuel use, noise and carbon dioxide emissions. Each hybrid loader
consumes 9-14%* less fuel compared to a traditional diesel burning
equipment of this size. This year, we upgraded our vehicle fleet
with more than 500 pieces of equipment. We replaced decades
old, less efficient trucks with 15-20% higher efficiencies of fuel
use and reduced emissions. We’ve also worked directly with our
employees using software programs to reduce idling and track
our fleet driving routes, optimizing travel times and over the road
safety.

We installed more than 1.6 miles of conveyors across our aggregate
operations in 2018. Capital projects like this provide long-term
solutions to moving heavy materials over large distances. Reducing
individual loads moving via dump truck helps to reduce dust, fuel,
and emissions.

ASPHALT

Asphalt plants require a considerable energy pull to start and heat
the product for paving. As a part of our smart energy campaign, we
are working to more effectively manage our power use at asphalt
plants across the organization. Using facilitators and Variable
Frequency Drives (VFD’s) allows us to save money by working with
our utility companies closely to pull from the grid when it’s least
expensive. In addition, the majority of our plants now use natural
gas as a heating fuel, which is a clean burning low carbon energy
choice.

LAND CONSERVATION AND
COMMUNITY PRESERVATION

Mining is an interim use of the land. We take pride and ownership
in working with our government agencies and community
partners to develop positive solutions for our stakeholders and
the next generation of land use.

An asphalt plant and aggregate location outside of Provo, Utah
had plans to expand and found ancient cultural resources
consisting of nine different artifacts from what is thought to
be the Fremont Cultural Group, possibly dating from 300 A.D. –
1300 A.D. In connection with local community stakeholders and
the Bureau of Land Management (BLM), we participated in a
series of community meetings to find an appropriate alternative
to mining the area under the artifacts. Our proposed alternative
was to leave the artifacts in place, undisturbed. We believe that
cultural resources of this nature tell a story that is of value in
that place alone, and should be preserved in order to provide a
way for local community members to see and experience this

Certification was developed to be accessible, credible, and to
drive change through strict requirements and rigorous third-
party evaluation. Since then, our conservation efforts and
subsequent certified habitat programs have expanded to
include thousands of managed acres. From planting pollinator
gardens to encouraging avian species, each of our Conservation
Certification programs is composed of unique projects that are
driven by the site’s landscape, the team’s objectives, and an
understanding of high value biodiversity areas.

In 2018, we added two new certifications into our portfolio of
Conservation Certifications. We now have six in total, with goals
to continue to expand and improve each year. We invite you to
take a look inside each program and the dedicated individuals
who commit their time to make these projects an important

Summit supports STEM education by working with
local schools to educate through hands-on experience.
This student was the first to answer a tough question
during a quarry tour in Eudora, KS, and was given
the honor of pushing the blast button.

COMMUNITY

Summit Materials embraces the uniqueness of each of our
operating companies, their culture, and their established
local partnerships with their respective communities. Our
commitments are demonstrated through varied efforts across
our geographical reach with each operating company supporting
their local areas in impactful ways. From volunteering at food
banks to hosting educational programs for students and river
clean up initiatives, we are focused on giving back in meaningful
ways.

We believe that we are an integral part of the communities in which
we operate and we work hard to have a positive impact in these
places. We invite you to explore our most impactful outreach
programs that show our commitment to being responsible
corporate citizens and contributing to our communities. Find out
more about what is happening at each company on our website
at www.summit-materials.com/sustainability/community.

ENRICHING STEM
EDUCATION OPPORTUNITIES

Science, Technology, Engineering and Math (STEM) is one of the
key focus areas of our community outreach and sustainability
program. Across the country, our operating companies are
dedicating efforts to help ensure that today’s students and
tomorrow’s leaders have access to great STEM education so
that they can gain the knowledge and experience needed to be
successful in their chosen field.

We have built dedicated educational programs that work with
local students and teachers year after year to inspire hands-
on curriculum focused on geology, environmental sciences,
chemistry and mining engineering. We believe that these efforts
help expand students’ knowledge of the working world and open
doors to our communities, enhancing dialogue and fostering
successful partnerships.

We provide resources to our companies to expand their STEM
programming, allowing us to build on valuable best practices.

TEACHING MINING
& RESTORATION

The cycle of mining and restoration is important
to us and our communities. In many of our STEM
programs, we show and teach students about how
we mine and the specific work that we do following
mining to restore, and rehabilitate lands.

GEOLOGY & CHEMISTRY

Our cement plant in Hannibal, Missouri helped
form the Mark Twain Area STEM Partnership and
takes pride in offering students a place to learn
hands-on science in an applicable setting. Our
teams give tours to hundreds of students each year,
teaching about rock layers, fossils, and the chemical
processes that go into manufacturing cement.

SAFETY & FUTURE JOBS

We hope that some of the students who take
our tours end up being our employees someday.
Showing students some of the best parts of our
work is important to us, from blasting, to paving
and everything in between. We often work with
local trade schools and universities to give students
hands-on learning opportunities and the chance to
get to know our company better.

KEEPING COMMUNITIES
VIBRANT & CLEAN

In 2018, six of our companies took on community
clean-up projects in an effort to improve the
places where we live, work and play. In Texas, we
adopted river miles on the Red River and the
Colorado River, both areas adjacent to aggregate
locations where we operate. In Roanoke, Virginia,
Boxley Materials’ employees participated in
a community-wide river festival event on the
Roanoke River, including a very popular ‘Recycle
Regatta’. Boxley helps sponsor the event each
year with the intention of celebrating and
educating the community about clean and
healthy waterways.

Continental Cement Company (CCC) partnered
with Livings Lands and Waters which is an
organization dedicated to cleaning and improving
major watersheds and rivers in the US. CCC
hosted clean ups in multiple mile-long sections
of the Mississippi River, including the four major
cities where we have terminals; New Orleans,
Minneapolis, St Louis, and Memphis. In 2018, their
community service along the Mississippi tallied
a total of 13,500 pounds of trash, more than 100
tires, and logged more than 250 volunteer hours.
CCC uses the Mississippi River to barge materials
to terminals along the river. Keeping this corridor
clean is an important way for us to give back to the
communities and environments that support our
business.

PHILANTHROPY & VOLUNTEERING

Participating in and improving our communities is a core value of Summit and our sustainability program. Our companies have steadily worked to
improve their volunteering and outreach programs in recent years, and their progress is notable. In 2018, we logged 1,650 volunteer hours across the
organization and are proud of our people for engaging and making a difference in their communities.

In addition to volunteering, we participate in our communities through meaningful philanthropy. Most notably in 2018, several employees near
Wilmington, North Carolina were very affected by Hurricane Florence. In response, we raised $15,000 from employee donations across the organization
which was matched by Summit Materials. In 2018, we donated more than $700,000 to organizations and communities across the country, helping
those in need. We’re proud of this work, and of our employees who volunteer their time and energy to efforts that make our communities and the
world a better place.

Several of our companies have philanthropic mixer trucks in their fleet. These vehicles often donate a portion of the proceeds from every yard of
concrete poured to the organization represented on the truck. This is an effective way to spread awareness while also contributing a percentage of
our proceeds to organizations that support those in need. Concrete Cares, an organization that supports those suffering from breast and childhood
cancer, is among our group of philanthropic ventures. Similarly, Camp Hope in Houston is an organization dedicated to veterans suffering from PTSD.
We love our big pink trucks, and the values they represent in our communities.

OUR SUSTAINABILITY LEADERSHIP

At Summit, sustainability is a team effort. We have a cross-
functional sustainability council with representation from every
function of the business and each of our operating companies.
Our team meets on a quarterly basis to ensure that sustainability
is embedded into our business, having a positive impact in our
communities, and growing long-term value for our stakeholders.

As a part of our annual in-person meeting, we spend one day
doing a volunteer project in a community where we operate.
The photo adjacent shows our team after picking up trash on a
two mile section of Highway 9 north of Silverthorne, CO in the
Arapahoe National Forest.

Our team is a passionate group of individuals from across North
America, who are helping to advance sustainability in their
companies, communities, and beyond. Their time, energy, and
dedication to this effort is profoundly impactful and appreciated.

Thanks to our team, sustainability is continuing to fold into the
fabric of our company, who we are, what we do, and what we
believe in.
