Invest at least 55% of our operating expendituresin research and development (R&D).
BASELINE: In 2020, 35% of operating
expenditures were invested in R&D.
PROGRESS: In 2023, 38% of operating
expenditures were invested in R&D.
Our R&D spending in 2023 represented 38%
of our operating expenditures, a moderateincrease vs. our 2020 baseline. In 2023, ourabsolute spending in R&D increased by 21%
compared to 2022, as we invest in technologies
that support our customers' leading edge
roadmaps to drive advances that are helping
transform the world. We expect our percentage
spending trend to continue toward our 2030
goal as we continue to invest significantly in
R&D innovation.
In addition, the expansion of thesemiconductor industry makes increased
manufacturing capacity essential to meetingcustomer demand and to supporting the
growth of our business. Toward those ends, in
2023, we started initial production at our new
manufacturing facility in Taiwan and brokeground on our new Colorado facility.

POWERING THE ELECTRIC VEHICLE INDUSTRY
Our work in innovation would not be what it is without
Vice President Rajiv Singh driving breakthroughs inchemical mechanical polishing (CMP) of emerging
materials. This technology plays a pivotal role insupporting the global transition to electric mobility,
as silicon carbide power devices are essential
components in powering electric vehicles (EVs) andother automotive applications. By providing leadingedge solutions for semiconductor manufacturers,
Entegris enables the production of these criticalcomponents, contributing to the reduction of fossil
fuel reliance.

For silicon carbide to effectively work in a powerdevice, it must be polished and free of defects.
Previously, the polishing process was time andresource intensive, taking up to 50 hours per wafer.
The team at Entegris, led by Rajiv Singh Ph.D.,
developed a process that polished the material in about
one hour, saving extensively on time and materials.
Recent enhancements have further reduced thepolishing time to minutes. This rapid polishing processcreates defect-free, atomically smooth surfaces toenable the creation of higher performing siliconcarbide devices that can decrease the charging timesof electric vehicle batteries by up to 50% compared to
traditional silicon devices. By facilitating the transition
to electric vehicles and development of clean energy
technologies, Entegris' silicon carbide innovations arecontributing to a more sustainable future.

“The environmental footprint for manufacturing was reduced by our process—both for us and our customers. It requires less chemistry and less materials to
make these wafers.”- Rajiv Singh Ph.D., Vice President of Chemical Mechanical Planarization Slurries

REDUCING IMPACT THROUGH
GREEN CHEMISTRY
Helping to lead our work in green chemistry is Frank
Onyemauwa, one of our sustainability R&D leaders,
whose commitment to green chemistry drives ourefforts toward eco-friendly manufacturing practices.
By advocating for the use of biomass-derived andrenewable materials, Onyemauwa demonstrates
our dedication to reducing environmental impact.
His goal is to replace 10 to 20% of the raw materials
that go into our products with biomass or renewablesources by 2030. Through his leadership, we are not
only innovating new materials and processes but also
fostering a culture of environmental awareness andresponsibility across all levels of the company.
Our venture into green chemistry is a significant
step in our commitment to sustainability. Exploring
bio-derived and biodegradable materials, especially“The practice of green chemistry is not left only to chemists and engineers. We dowhat we can to make people aware, whether you’re working as an operator or in
the shipping department, we all have the obligation to minimize waste production
in all our activities.”- Frank Onyemauwa Ph.D., Sustainability R&D leader

Additionally, our dedication to green chemistryaddresses challenges like cost-effectiveness andwidespread adoption. Overcoming obstacles such as
higher upfront costs associated with green materials
requires innovation and creativity. Collaboration withstakeholders and leveraging emerging technologies
bridge the gap between green chemistry ideals andpractical implementation. Through ongoing research,development, and strategic partnerships, we areconfident in our ability to drive meaningful progress
toward a greener, more sustainable future.

LOOKING AHEAD
We are intensifying our efforts to embedsustainability in the earliest stages of new
product development. A prime example of thiscommitment is the innovative design of ourAtmospheric Micro-contamination Control
filters, which not only minimize environmental
impact but also deliver significant value to ourcustomers. Our new design replaces metal witha recyclable polymer, allowing the media to be
repurposed for energy production, thus reducing

SUCCESSFUL STOP WORKAUTHORITY
We empower employees to exercise their
responsibility to stop work when they see
hazards that pose a risk to themselves or theircolleagues. To ensure teams are comfortablewith and celebrated for exercising this criticalresponsibility, we executed a multifaceted
training and communication campaign to shareexamples of employees demonstrating theircommitment to safety and using their training to
identify and fix potential safety concerns. One
specific example of our Stop Work program inaction was in Reno, NV, when a contractor was
spotted standing on the top step of a ladder, an
Entegris team member intervened, prompting
the contractor to use a taller ladder for safety. A
similar example took place in Danbury, CT, whena supervisor halted work on an equipment lift
due to safety concerns, discussing adjustmentswith the team to ensure safe continuation.

pools in a year. This marked the beginning of a two-year plan to further

into other water-consuming processes. Also, installing two new highefficiency washers has slashed water usage by two-thirds, contributing
an additional 34,000 m³ of water savings.
Meanwhile, at our Chaska, MN facility, progress toward our water
reduction goal in 2023 involved the initiation of a water recycling
process for water-cooled equipment systems. With a weekly water
consumption of 350 gallons, the implementation of a filtering reuseprocess is expected to prevent the withdrawal of 50,000 gallons ayear. Building on this success, similar systems are being explored for

As part of our responsible sourcing efforts, Entegris requires
suppliers providing tantalum, tin, tungsten, or gold, or products
containing these components, to submit traceability information
allowing us to track the minerals back to their source. Additionally,
we expect our suppliers to establish their due diligence programs tocertify the conflict-free status of the materials supplied to Entegris.

We are also committed to reducing waste as part of our broader
