MaxCyte Reports Second Quarter 2026 Financial Results

Reports total revenue of $7.3 million for the second quarter of 2026, including $6.5 million of core revenue and $0.8 million of SPL Program-related revenue

Reiterates Full Year 2026 Guidance

Repurchased approximately $5.5 million of common stock to date under the Company’s $10 million share repurchase program authorized by the Board

Following end of quarter, announced strategic, multi-platform technology license partnership with Genentech in July

ROCKVILLE, MD, August 12, 2026 — MaxCyte, Inc. (NASDAQ: 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 second quarter ended June 30, 2026 financial results and reiterated its 2026 guidance.

"We are pleased with our second quarter results, which were ahead of our expectations, driven by execution on instrument placements and stability in processing assembly sales," said Maher Masoud, President and CEO of MaxCyte. "A significant development for MaxCyte was the recent signing of our first multi-platform technology license partnership with large pharma, an enterprise-level agreement with Genentech that we believe will unlock meaningful new opportunities for MaxCyte. Separately, our SPL portfolio remains a key driver of long-term value as evident by growing commercial royalty revenue and the advancement of a significant number of SPL programs through the clinic. Lastly, our goal has been to return to revenue growth while reducing our net losses. In the first half of 2026, we delivered a meaningful reduction in net loss and expect to benefit further as we continue to execute against our plan and return to revenue growth.”

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 these non-GAAP measures 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 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 forward-looking statements in this Presentation are based on management's current expectations and beliefs and are subject to a number of risks, uncertainties and important factors that may cause actual events or results to differ materially from those expressed or implied by any forward-looking statements contained in this Presentation, including, without limitation, statements regarding the Company's future growth, results of operations, performance, future capital and other expenditures (including the amount, nature and sources of funding thereof), competitive advantages, business prospects and opportunities. 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, 2025, 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.

No statement in this Presentation is intended to be, or intended to be construed as, a profit forecast or profit estimate or to be interpreted to mean that earnings per Company share for the current or future financial years will necessarily match or exceed the historical earnings per Company share. As a result, no undue reliance should be placed on such statements.

No representations or warranties (expressed or implied) are made about the accuracy of any such forward-looking statements. This Presentation contains Adjusted EBITDA, which is a non-GAAP measure defined as earnings before interest, taxes, depreciation, amortization, goodwill impairment and one-time restructuring charges. MaxCyte believes that Adjusted EBITDA provides useful information to management and investors relating to its results of operations. The company’s management uses these non-GAAP measures 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 Adjusted 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 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 Presentation. The Company urges investors to review the reconciliation and not to rely on any single financial measure to evaluate its business.
