Exhibit 99.1

Bruker Corporation and PhenomeX Inc. Announce Definitive Agreement for

Bruker to Acquire PhenomeX in All-Cash Transaction

Acquisition initiates Bruker’s entry into functional single-cell biology research solutions

BILLERICA, Massachusetts and EMERYVILLE, California, August 17, 2023 — Bruker Corporation (Nasdaq: BRKR) and PhenomeX Inc. (Nasdaq: CELL) today announced that they have signed a definitive agreement for Bruker to acquire PhenomeX for $1.00 per share in an all-cash transaction. The proposed acquisition values PhenomeX at a total equity value of approximately $108 million. PhenomeX is a functional cell biology company that provides single-cell biology research tools to deliver deep insights into cellular function and new perspectives on phenomes and genotype-to-phenotype linkages.

PhenomeX was formed in early 2023 through the combination of Berkeley Lights and IsoPlexis, and PhenomeX currently has an installed base of more than 400 instruments. PhenomeX provides single-cell biology workflows with instruments, software and molecular biology reagents. The PhenomeX products include the key Beacon^® Optofluidic platform, as well as the IsoLight^® and IsoSpark^® proteomics barcoding platform. The Beacon Optofluidic system enables researchers to accelerate biologics product development by functional characterization of tens of thousands of single cells in parallel, while maintaining the cells in a healthy state for further genomic and proteomic profiling, connecting phenotype with genotype and other multiomic information. The Protein Barcoding Suite includes the IsoLight^® and IsoSpark^® instruments, which automate multiplexed measurements of the extracellular proteome and of the intracellular proteome of single cells for translational research.

Dr. Mark R. Munch, President of the Bruker NANO Group, commented: “The unique single-cell analysis platforms of PhenomeX are enabling researchers to more rapidly and precisely unlock new insights in functional cell biology research leading to important discoveries across the large and rapidly growing markets of antibody therapeutics, cell line development, cell therapy and gene therapy. This acquisition will mark Bruker’s entry into single-cell biology research tools, which complements Bruker’s emerging spatial biology business—in support of our transformational Project Accelerate 2.0 strategy.”

“This is an important next step for PhenomeX as we bring together two companies passionate about innovating for our customers to support human health,” said Siddhartha Kadia, PhD, Chief Executive Officer and Director of PhenomeX. “By joining forces with Bruker, a respected and innovative global leader in life science research tools, we will not only enhance PhenomeX’s differentiated, high-value technologies but also our customers’ abilities to discover novel antibodies and accelerate development and manufacturing of cell and gene therapies. I am very proud of the PhenomeX team, and excited to work with our new colleagues at Bruker as we enter our next phase of growth.”

For Bruker, Perella Weinberg Partners acted as financial advisor and Morgan Lewis as legal advisor. For PhenomeX, William Blair & Company, L.L.C. acted as financial advisor and Freshfields Bruckhaus Deringer LLP as legal advisor.
