TriLink BioTechnologies® Expands Capabilities with Launch of ‘Analytical Sciences Center of Excellence’

SAN DIEGO – TriLink BioTechnologies® (TriLink), a Maravai LifeSciences company
(NASDAQ: MRVI) and global provider of life science reagents and services, has launched its Analytical
Sciences Center of Excellence (ASCE) hub. Expanding its comprehensive suite of analytical testing
capabilities, this new center of excellence will minimize the delays and unexpected costs typically
associated with outsourced testing to multiple laboratories. This new center of excellence will serve as
the hub for all analytical innovation and the Quality Control laboratories across the organization’s
manufacturing network.

Located within Maravai LifeSciences’s Pacific Center Boulevard facility in San Diego’s Sorrento Valley,
the ASCE will operate out of a 4,000-square- lab equipped with advanced instrumentation and support
developers as they advance their drugs – starting with plasmid DNA and continuing through mRNA
manufacturing and release.

“TriLink's new Analytical Sciences Center of Excellence will be a transformative force in the development
of nucleic acid therapies,” shared Khaled Yamout, Senior Director of Analytical Services at TriLink. “This
new lab will allow us to expand our analytical capabilities to meet the growing demands of the market,
including specific method development.”

Leaning on decades of technical expertise, TriLink continues to lead the market with mRNA specific
analytical services, having developed and qualified 10 types of unique methods for the characterization
of mRNA covering 40 various constructs. With this expansion, the center of excellence builds upon the
organization’s comprehensive method development for construct-specific assays with new
instrumentation to improve NMR, NGS, and LNP characterization. The center of excellence will also be
responsible for developing cutting-edge analytical methodologies, including mRNA fingerprinting and
sequencing.

“We continue to witness exciting growth in nucleic acid therapeutics – and rapid expansion calls for
rapid innovation,” added Kevin Lynch, TriLink’s VP and GM of GMP Operations. “The ASCE’s centralized
analytical capabilities and development of analytical methodologies for the characterization of nucleic
acids will advance the industry as we continue to find ways to meet the needs of developers working on
life-saving therapeutics.”

In addition to the ASCE’s suite of analytical services, TriLink® has a robust ® mRNA capping portfolio,
advanced scale-up capabilities, and unrivaled expertise in mRNA, oligonucleotide, and plasmid
production. Leveraging more than 25 years of experience, TriLink® serves companies dedicated to
advancing therapeutics, vaccines, and diagnostics by delivering exceptional Contract Development and
Manufacturing Organization (CDMO) services.
