MXCT MaxCyte Inc

MaxCyte, Inc., (Nasdaq: MXCT; LSE: MXCT), a leading cell-engineering focused company providing enabling platform technologies to advance the discovery, development and commercialization of next-generation cell therapeutics, today announced the completion of an internal operational review, initiated earlier this year following the appointment of Maher Masoud as President and Chief Executive Officer. This “bottom-up” review focused on optimizing new product development, manufacturing, commercial execution, and capital allocation to enhance efficiency and align resources with strategic priorities. As part of an effort to streamline operations, the company made adjustments to its workforce which affected 21 positions, reflecting approximately 15% of its personnel globally, including both directly employed individuals and those engaged through third-party employer-of-record (EOR) arrangements. This adjustment is designed to improve accountability, better align personnel resources with the company’s goals, and position MaxCyte for long-term growth.

Anticipated cost savings in 2025 as a result of this action are expected to be about $5.8 million. These savings will help accelerate new strategic initiatives addressing customer needs in cell engineering and manufacturing adjacent to electroporation in the cell therapy manufacturing process. Following this adjustment, combined with other personnel decisions made throughout the year, MaxCyte expects to end the year with 116 employees, compared with 143 employees at the end of 2023 (in each case, inclusive of individuals employed through EOR arrangements).

Reflecting the company’s strengthened operational foundation and continued strong performance, MaxCyte is raising its full-year 2024 core revenue guidance to project 6% to 8% growth compared to 2023.

“2024 has been a good year for MaxCyte. We signed six SPL agreements, added a cell therapy industry veteran to the board and outperformed our financial commitments to the investment community. Throughout the year, we have implemented a more focused, and accountable, operating philosophy at MaxCyte, taking important and necessary steps to drive innovation and growth in a capital efficient manner,” said Maher Masoud, President and CEO at MaxCyte. “I would like to thank the employees impacted by today’s announcement for their contributions to MaxCyte. Core business momentum remains strong as we exit 2024, resulting in an increase to our core revenue growth guidance. I am incredibly optimistic about the future of MaxCyte and am excited about the opportunities ahead to drive the cell therapy industry forward.”

2024 Revenue Guidance

MaxCyte increases 2024 revenue guidance for core business revenue and affirms SPL Program-related revenue guidance.

MaxCyte now expects full year 2024 core business revenue of 6% to 8% growth compared to 2023. SPL Program-related revenue is expected to be approximately $6 million. The outlook for the full year does not include SPL Program-related revenue from Vertex/CRISPR’s CASGEVY™.

MaxCyte continues to expect to end 2024 with approximately $185 million in cash, cash equivalents and investments.
