Illumina Underscores Commitment to Shareholder Value and Responds to Carl Icahn's Statements

• Illumina's plan will maximize shareholder value
• Illumina is engaged with regulators to define GRAIL's path forward as expeditiously as possible
• Icahn's director nominees do not add value to the Board and will damage Illumina's core business

SAN DIEGO, March 20, 2023 /PRNewswire/ -- Illumina (NASDAQ: ILMN), a global leader in DNA sequencing and array-based technologies, today issued the following response to Carl Icahn's public statements and letters to Illumina's shareholders dated March 13 and March 15, 2023:

Illumina's innovation engine delivers shareholder value to the core business

Illumina has a successful long-term track record of innovating to fundamentally advance the understanding of biology and improve human health. Illumina is the only profitable, pure-play genomics tools company in existence. This commitment to excellence and successful execution includes profitable, double-digit revenue growth over the past decade. By adding Icahn's director nominees, who lack experience in, and knowledge of, the business and industry, Illumina risks jeopardizing the long-term success of its core franchise which is primed to achieve rich, long-term shareholder returns over the next several years and beyond.

Illumina continues to advance its innovation roadmap in support of its long-term growth trajectory. Since the successful launch of NovaSeqtm X, Illumina's latest flagship high-throughput instrument, there has been unprecedented demand from both research and clinical customers, while the company delivered record NextSeqtm 1000 and 2000 mid-throughput sequencing platform shipments and orders in the fourth quarter of 2022. New product introductions such as NovaSeqtm X as well as upgrades across the rest of the portfolio, including Illumina Complete Long Reads and NovaSeqtm 6000Dx, are game-changing innovations that maintain the company's position as the leading innovator in sequencing and drive long-term sustainable shareholder value.

Over the last two decades, Illumina has maintained leadership in research and clinical genomics. It has built an installed base of more than 23,000 sequencing systems across more than 9,500 customers in 155 countries, as well as secured more than 8,800 patents for its technologies.

While remaining committed to innovation, Illumina's management team also focuses on managing costs, including a restructuring in late 2022. Illumina produces strong gross margins and operating margins, while all other pure-play genomics tools companies generate operating losses. Illumina's share price has outpaced other pure-play genomics tools companies by 26 percentage points over the last two years.

On March 14^th during a CNBC appearance, Carl Icahn recognized the "great company in Illumina, and in gene sequencing." On this much, we agree. Illumina has created a unique and positive track record due to its experience identifying, nurturing, and bringing innovation to market. Illumina's world-leading innovation portfolio is the result of deep understanding of biology, the challenges of biological discovery and engineering requiring five to ten year science and technology investments. A short-term approach to managing innovation would not have created the multiple technologies that make NovaSeqtm X a world-leading product, or any other product in Illumina's portfolio.

GRAIL has strong traction; Illumina is taking all steps to maximize GRAIL's value

GRAIL has tremendous long-term value creation potential and is a great example of Illumina's innovation strategy. As a transformative, clinically-validated technology based on Next Generation Sequencing (NGS) and serving an underpenetrated $44-plus billion cancer screening market, GRAIL offers the only commercially available multi-cancer early detection test, Galleritm. The test has enjoyed the fastest first-year revenue ramp of any cancer screening test and generated $55 million of revenue in 2022, even ahead of anticipated commercial or government-based reimbursement. It is on track to deliver $90 ? 110 million of revenue in 2023.

To date, more than 60,000 Galleritm tests have been ordered and have impacted the lives of patients who have had the opportunity to take this groundbreaking test. In the UK, the National Health Service (NHS) has enrolled 140,000 participants in a study of the Galleritm test. If the study continues to be successful, the NHS is expected to roll out the Galleritm test to 1 million people in the UK beginning in 2024.

Illumina is moving as quickly as possible to work through the legal and regulatory processes to maximize value for shareholders with respect to GRAIL, including defining the conditions and options of a potential divestiture. Illumina has challenged the European Commission's (EC) jurisdiction to review the GRAIL acquisition. The final decision is expected in late 2023 or early 2024. Winning a jurisdictional appeal eliminates any EC fine and gives the greatest optionality for Illumina to maximize value for shareholders. If Illumina loses the EU jurisdictional appeal, the company will follow the terms of the final divestiture order, expeditiously and in a manner that is in the best interests of its shareholders. The Board's ongoing management of the GRAIL process is carefully considered and informed by thorough analysis.

Icahn does not contest that GRAIL represents a valuable asset to both Illumina's shareholders and global human health. Indeed, on CNBC on March 14^th, he referred to GRAIL as Illumina's "best equipment." He also acknowledges he doesn't understand the regulatory process and has not offered any new ideas for a more rapid resolution for GRAIL. As for the EU regulatory process, he admits he's "not a lawyer" and that "[he hasn't] really studied it." Icahn has no ability to accelerate the legal and regulatory processes and neither do his nominees.

Strong independent Board committed to maximizing shareholder value

A company of Illumina's value creation potential requires a Board invested and experienced in creating clinical markets, driving operational excellence, harnessing the power of science, and realizing a vision for future growth. Illumina's Board brings extensive and diverse business, financial, operating, regulatory and scientific backgrounds in the life sciences and technology sectors, and have presided over the growth of biotech companies, run public life sciences and technology companies, and brought world-class products to market. The Board is led by an independent chair and all nine members are independent, except for the CEO. The Board and management team have a proven track record of successfully managing the core business, and a plan to resolve the acquisition of GRAIL expeditiously and in a manner that is in the best interests of Illumina's shareholders.

Illumina's Board of Directors is committed to maximizing value for all shareholders and has always welcomed constructive engagement with the investment community. Illumina's Nominating/Corporate Governance Committee interviewed each of Icahn's nominees and found that they lacked relevant skills and experience.

At this time, shareholders are not required to take any action with respect to Icahn. Illumina will file preliminary materials with respect to the 2023 Annual Meeting of Shareholders in the coming weeks.
