ROCKVILLE, MD, March 11, 2025 — 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 its fourth quarter and full year ended December 31, 2024 financial results and initiated its 2025 guidance.

Fourth Quarter and Full Year Highlights

● Total revenue of $8.7 million in the fourth quarter of 2024, a decrease of 45% over the fourth quarter of 2023. The decrease in total revenue was due to multiple one-time approval milestones in the fourth quarter of 2023.

● Core business revenue of $8.6 million in the fourth quarter of 2024, an increase of 20% over the fourth quarter of 2023.

● Strategic Platform License (SPL) Program-related revenue was $0.1 million for the fourth quarter of 2024, compared to $8.5 million in the fourth quarter of 2023.

● Total revenue of $38.6 million for the full year 2024, a decrease of 6% over the full year 2023.

● Core business revenue of $32.5 million for the full year 2024, an increase of 9% over the full year 2023.

● SPL Program-related revenue was $6.1 million for the full year 2024, compared to $11.5 million in full year 2023.

● Ended the year with 28 active SPL agreements that include 18 active programs currently in the clinic (defined as programs with at least a cleared IND or equivalent) and 1 active commercial program.

● Total cash, cash equivalents and investments were $190.3 million as of December 31, 2024.

“We are pleased to report strong financial results in 2024, including a return to core revenue growth and disciplined cash management, driven by the execution of our team,” said Maher Masoud, President and CEO of MaxCyte. “We signed a record six SPLs in 2024 and continue to see momentum in the SPL pipeline with the addition of TG Therapeutics early in 2025. We also implemented a more disciplined capital and operational approach at MaxCyte, which has already enabled new strategic initiatives, and a more efficient and streamlined business, underpinning our commitment to long-term value creation for our shareholders. In 2025, we will continue to drive strong commercial execution, support the progression of SPL programs through the clinic, and make disciplined investments to position MaxCyte as a premier cell engineering solutions provider, including the integration and growth of SeQure Dx.”

Non-GAAP Financial Measures

This press release contains EBITDA, which is a non-GAAP measure defined as earnings before interest income and expense, taxes, depreciation and amortization. MaxCyte believes that EBITDA provides useful information to management and investors relating to its results of operations. The company’s management uses this non-GAAP measure to compare the company’s performance to that of prior periods for trend analyses, and for budgeting and planning purposes. The company believes that the use of EBITDA provides an additional tool for investors to use in evaluating ongoing operating results and trends and in comparing the company’s financial measures with other companies, many of which present similar non-GAAP financial measures to investors, and that it allows for greater transparency with respect to key metrics used by management in its financial and operational decision-making.

This press release also contains Non-GAAP Gross Margin, which we define as Gross Margin when excluding SPL program related revenue and reserves for excess and obsolete inventory.  The Company believes that the use of Non-GAAP Gross Margin provides an additional tool to investors because it provides consistency and comparability with past financial performance, as Non-GAAP Gross Margin excludes non-core

4

revenues and inventory reserves, which can vary significantly between periods and thus affect comparability.

Management does not consider these Non-GAAP financial measures in isolation or as an alternative to financial measures determined in accordance with GAAP. The principal limitation of these Non-GAAP financial measures is that they exclude significant revenues and expenses that are required by GAAP to be recorded in the Company’s financial statements. In order to compensate for these limitations, management presents these Non-GAAP financial measures along with GAAP results. Non-GAAP measures should be considered in addition to results prepared in accordance with GAAP, but should not be considered a substitute for, or superior to, GAAP results. Reconciliation tables of net loss, the most comparable GAAP financial measure, to EBITDA, and Gross Margin, the most comparable GAAP financial measure, to Non-GAAP Gross Margin, are included at the end of this release. MaxCyte urges investors to review the reconciliation and not to rely on any single financial measure to evaluate the company’s business

Any investment or investment activity to which this Presentation relates is available only to relevant persons. Certain statements in this Presentation are, or may be deemed to be, forward-looking statements within the meaning of the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995, including but not limited to statements regarding our expected potential future revenue.

These and other risks and uncertainties are described in greater detail in the section entitled "Risk Factors" in our Annual Report on Form 10-K for the year ended December 31, 2023, our quarterly reports for the periods ended March 31, 2024, June 30, 2024, and September 30, 2024, as well as discussions of potential risks, uncertainties, and other important factors in the other filings that we make with the Securities and Exchange Commission from time to time.

Any forward-looking statements represent our views only as of the date of this Presentation and should not be relied upon as representing our views as of any subsequent date. We explicitly disclaim any obligation to update any forward-looking statements, whether as a result of new information, future events or otherwise. No representations or warranties (expressed or implied) are made about the accuracy of any such forward-looking statements. This Presentation also contains Non-GAAP Gross Margin, which we define as Gross Margin when excluding SPL program related revenue and reserves for excess and obsolete inventory. The Company believes that the use of Non-GAAP Gross Margin provides an additional tool to investors because it provides consistency and comparability with past financial performance, as Non-GAAP Gross Margin excludes non-core revenues and inventory reserves, which can vary significantly between periods and thus affect comparability. Management does not consider these Non-GAAP financial measures in isolation or as an alternative to financial measures determined in accordance with GAAP. The principal limitation of these Non-GAAP financial measures is that they exclude significant revenues and expenses that are required by GAAP to be recorded in the Company’s financial statements. Non-GAAP measures should be considered in addition to results prepared in accordance with GAAP, but should not be considered a substitute for, or superior to, GAAP results. A reconciliation table of Gross Margin, the most comparable GAAP financial measure, to Non-GAAP Gross Margin is included in the appendix of this release. © 2024 MaxCyte, Inc. All Rights Reserved
