•

Full year 2025 revenue of $738 million, a year-over-year increase of 16% for both reported and organic non-COVID

WALTHAM, Mass., February 24, 2026 -- Repligen Corporation (NASDAQ:RGEN), a life sciences company focused on bioprocessing technology leadership, today reported financial results for its fourth quarter of 2025, covering the three- and twelve- month periods ended December 31, 2025. The Company is also providing financial guidance for the full year 2026.

Olivier Loeillot, President and Chief Executive Officer of Repligen said, “We had a great finish to 2025 with 14% organic growth in the quarter led by Analytics and Proteins. As a result, we exceeded the high end of our October revenue and adjusted operating income guidance. We are thrilled by our strong performance in 2025 with 16% organic non-COVID growth driven by traction across our differentiated portfolio, while continuing to expand margins.

“As we turn the page to 2026, we are excited about our product portfolio, the team we've built, and the strategy we are executing. We are investing with intention: expanding our commercial presence and scaling our operations for greater agility. We remain focused on innovation that enables customers to accelerate development and improve yields. Our initial 2026 guidance calls for 10% - 14% revenue growth, which we believe is an appropriate starting point for the year and includes a two-point gene therapy headwind. In addition, we expect 150 bps of adjusted operating margin expansion at the midpoint.”

Executed on All 2025 Strategic Priorities.

Non-GAAP Measures of Financial Performance

To supplement our financial statements, which are presented on the basis of U.S. generally accepted accounting principles (“GAAP”), the following Adjusted (“non-GAAP”) measures of financial performance are included in this release: organic non-COVID revenue and non-COVID revenue growth; organic revenue and organic revenue growth; adjusted cost of goods sold, adjusted gross profit and adjusted gross margin; adjusted R&D expense and adjusted SG&A expense; adjusted income from operations and adjusted operating margin; organic adjusted operating margin year-over-year change; adjusted pre-tax income; adjusted net income and adjusted net income margin; adjusted earnings per share (diluted); adjusted earnings before interest, taxes, depreciation and amortization (EBITDA), and adjusted EBITDA margin. The Company provides the impact of foreign currency translation, to enable determination of revenue and margin growth rates at constant currency. To calculate the impact of foreign currency translation, the Company converts the reported amounts from local currency to U.S. dollars using constant foreign currency exchange rates in the current and prior year periods.

The Company’s non-GAAP financial results and/or non-GAAP guidance exclude the impact of: acquisition and integration costs; restructuring charges including the costs of severance and accelerated depreciation among other non-cash charges; inventory step-up costs and adjustments; incremental costs attributed to CEO transition; contingent consideration related to the Company’s acquisitions; intangible amortization costs; non-cash interest expense related to the accretion of the debt discount; amortization of debt issuance costs related to Company’s convertible debt; foreign currency impact of certain intercompany loans; and, the related impact on tax of non-GAAP charges. These costs are excluded because management believes that such expenses do not have a direct correlation to future business operations, nor do the resulting charges recorded accurately reflect the performance of our ongoing operations for the period in which such charges are recorded. Further, organic adjusted operating margin year-over-year change excludes the effect of adjustments above, as well as the impact of mergers and acquisitions and foreign exchange. This measure is used by the Company in periods of acquisition because the timing, size and number of such transactions and their related impact on the financial statements may vary and make comparison of long-term results difficult.

All reconciliations of above GAAP figures to adjusted (non-GAAP) figures are detailed in the tables included later in this press release. When analyzing the Company’s operating performance and guidance, investors should not consider non-GAAP measures as a substitute for the comparable financial measures prepared in accordance with GAAP.

The Company does not provide GAAP financial measures on a forward looking basis as the Company is unable to provide a quantitative reconciliation of forward-looking non-GAAP measures to the most directly comparable forward-looking GAAP measure, without unreasonable effort. The Company cannot reasonably predict items including, but not limited to, the timing and amount of future restructuring, cost-savings actions and acquisition and integration related costs. These items are generally uncertain and are not indicative of ongoing operations of the business, and the impact could be material to our results in accordance with GAAP.

Forward-Looking Statements

This press release contains forward-looking statements, which are made pursuant to and in reliance upon the safe harbor provisions of federal securities laws, including the Private Securities Litigation Reform Act of 1995, Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended.

FOOTNOTES FOR ALL TABLES ABOVE (amounts in thousands, except share data):

(1)

In July 2023, we began restructuring activities to simplify and streamline our organization and strengthen the overall effectiveness of our operations. The Company continued further restructuring activities during 2025 including severance, employee-related and facility exit costs. Cost of goods sold includes the benefit received from the sale of inventory that had previously been reserved as part of the restructuring plan of $1,704 and $4,972 for the three and twelve months ended December 31, 2025, respectively.

(2)

Includes $16 and $22,362, of incremental stock compensation expense, recorded during the three and twelve months ended December 31, 2024, respectively, attributable to the transition of the Company’s Chief Executive Officer (“CEO”) to Executive Chair of the Board announced by the Company on June 12, 2024. The incremental stock compensation expense was the result of the modification of the unvested equity awards held by the CEO immediately prior to the modification. This resulted in the revalue of his unvested awards and a change in his remaining requisite service period due to his change in duties upon transitioning to Executive Chair of the Board.

(3)

During the three months ended December 31, 2025 and 2024, we recorded foreign currency (gains) and losses on certain intercompany loans of ($867) and $4,883, respectively, and ($867) and $5,509 for the twelve months ended December 31, 2025 and 2024, respectively. The impact is recorded in Other (expenses) income, net within the Consolidated Statements of Operations.

(4)

Includes other expenses that are non-indicative of our ongoing performance and one-time events relating to a cybersecurity incident, net of insurance, and costs associated with the restatement of previously issued financial statements.

(5)

GAAP loss per share - diluted for the three and twelve months ended December 31, 2024, was determined excluding the effect of dilutive shares as the impact of such shares would have been antidilutive due to the net loss for the period, while the adjusted earnings per share - diluted for the same period was determined based upon diluted shares.

(6)

Excludes $19 of accelerated depreciation related to the restructuring plan for the twelve months ended December 31, 2024. This amount is included in the depreciation line item of this table for that period.
