Organization Structure and Supply Chains

Illumina has approximately 10,200 employees and had revenues in excess of USD $4.5
billion in 2022.
Illumina’s main manufacturing facilities are in the U.S. and Singapore. We directly sourcecomponents for our products, design parts, prototype parts, software, and manufacturing equipmentfrom over 20 countries across the Americas, Asia, Europe, and Africa, and the first tier of our supply
chain includes approximately 500 suppliers. We currently have over 190 Channel Partners who we
consider to be a key component of our global supply chain.

PolicyIllumina is committed to conducting its business in compliance with all applicable laws andregulations, and with the highest ethical standards. We have therefore adopted several relevant
policies applying to key stakeholders:•Illumina Code of Conduct: applies to all of Illumina’s employees, consultants, temporary workers,officers, and members of the Board of Directors, regardless of location, seniority level, businessunit, function, or region. The Code of Conduct requires Illumina personnel to bring company
expectations regarding legal and ethical conduct to the attention of all suppliers and channel
partners (including expectations regarding forced and child labor, and human trafficking), toperform due diligence when choosing business partners to ensure that suppliers meet Illumina’s
standards, and to be vigilant for any signs that third parties are violating legal or ethicalrequirements, including local employment and safety laws.
•Supplier Code of Conduct: applies to all of Illumina’s suppliers and requires suppliers to comply
with standards relating to various issues, including Modern Slavery, human rights, labor rights,
as well as environment, health and safety. Suppliers are expected to ensure that their own
subcontractors comply with the standards set out in the Supplier Code of Conduct.

•Channel Partner Code of Conduct: applies to all of Illumina’s Channel Partners as well as theiraffiliates and subsidiaries across the globe and outlines responsibilities with respect to ensuringthat their business is conducted with integrity and follows all applicable laws and regulations.
The Channel Partner Code of Conduct includes a commitment to proactively contribute tocontinued education, fair treatment, and safe working conditions for all Channel Partner
employees. It also includes a commitment to never employ under-age individuals, use forcedlabor, or corporal punishment to discipline employees.

Working with Business Partners
Illumina seeks to build relationships with Business Partners who share our commitment to satisfying
all legal, ethical, and human rights obligations. We seek Business Partners who are proactive incontributing to the continued education, fair treatment, working conditions and betterment ofemployees and who provide equal employment opportunity. Illumina is committed to respecting
human rights and to treating every person with dignity and respect, and we expect our Business
Partners to do the same. As set out in our Commitment to Human Rights, Illumina expects ourBusiness Partners to act in accordance with internationally recognized human rights standards,
including the United Nations Universal Declaration of Human Rights, International Covenant on Civil
and Political Rights, the International Labor Organization’s Declaration on Fundamental Principles
and Rights at Work, and the United Nations Guiding Principles on Business and Human Rights.
We do not knowingly do business with Business Partners who employ under-age individuals, use
forced labor, or corporal punishment to discipline employees, regardless of whether such practices
are permitted by applicable law.
How do we achieve this?

Risk Assessment, Verification, and Due Diligence
Illumina performs due diligence when choosing Business Partners to verify that they meet ourstandards, as set out in our Supplier Code of Conduct and Channel Partner Code of Conduct asapplicable. Our due diligence includes conducting risk assessments when on-boarding new
suppliers or Channel Partners and conducting periodic assessments of performance. We additionallyimplement contractual and procedural safeguards to monitor compliance with our human rights
expectations for Business Partners.
Illumina is aware that certain regions and industries in its supply chain pose a higher risk for modernslavery. For this reason, Illumina takes steps to enhance its Modern Slavery risk mitigation strategies
for such higher risk areas. For example, as set out in our Supplier Code of Conduct, Illumina expects
suppliers that procure tantalum, tin, tungsten, and gold to commit to the Responsible BusinessAlliance Code of Conduct. The Responsible Business Alliance seeks to leverage collective action totackle systemic risks surrounding Modern Slavery in the sourcing of certain metals lower down in thesupply chain. In addition, Illumina partners with Source Intelligence to evaluate our supply chainregarding the use of conflict minerals, and Beroe Inc. to calculate environmental, social, andgovernance impact scores for our direct suppliers.
Illumina is committed to ensuring that it has appropriate grievance mechanisms in place so that
employees and other stakeholders are able to raise concerns about conduct in our supply chainsand global operations that might suggest Modern Slavery. To that end, the Illumina Code of Conduct
directs all employees and Business Partners to report potential violations or concerns through avariety of channels, including to our human rights and ethics team (ethicsteam@illumina.com) or ourcompliance hotline which may be accessed on Illumina’s webpage here.

Supply Chain Contractual Controls, Audits, and Certification
Illumina requires that its suppliers and Channel Partners comply with applicable laws andregulations. We share our Supplier Code of Conduct and Channel Partner Code of Conduct, which
describes Illumina’s expectations for legal and ethical conduct, with all direct suppliers and Channel
Partners, and we are vigilant for any signs that third parties are violating legal or ethicalrequirements, including local environmental, employment, and safety laws.

Channel Partner Compliance and Supply Chain groups oversee compliance with the Channel
Partner Code of Conduct and the Supply Chain Code of Conduct. Illumina takes the obligation toinvestigate reports of potential violations of law, non-compliance with Illumina’s Code of Conduct andCorporate Policies, and unethical conduct very seriously. Illumina is committed to impartiallyinvestigating all such reports where warranted and remediating any such violations in a fair andconsistent manner.

Measuring Performance
As its business and operations grow, Illumina identifies and builds Key Performance Indicators(KPIs) against which the company can assess year on year progress in ensuring it is effectively
tackling Modern Slavery in its supply chains and global operations. In 2022, Illumina started trials ofdifferent software platforms for managing and monitoring supply chain partners for modern slavery
risks. These tools enable Illumina to measure its suppliers’ risk on an aggregated and individual
scale. Illumina is committed to using these tools for assessing its efforts to prevent modern slavery in
its supply chains.
