Thank you, operator, and welcome, everyone, to our 2025 fourth quarter report. On this call, we will cover business highlights and financial performance for the 3- and 12-month periods ended December 31st, 2025, and we'll provide financial guidance for the full year 2026. Joining us on the call today are Repligen's President and Chief Executive Officer, Olivier Loeillot; and our Chief Financial Officer, Jason Garland. As a reminder, the forward-looking statements that we make during this call, including those regarding our business goals and expectations for the financial performance of the company are subject to risks and uncertainties that may cause actual events or results to differ. Additional information concerning risks related to our business is included in our quarterly reports on Form 10-Q, our annual report on Form 10-K and our current reports, including the Form 8-K that we are filing today and other filings that we make with the Securities and Exchange Commission. Today's comments reflect management's current views, which could change as a result of new information, future events or otherwise. The company does not oblige or commit itself to update forward-looking statements, except as required by law. During this call, we are providing non-GAAP financial results and guidance, unless otherwise noted. Reconciliations of GAAP to non-GAAP financial measures are included in the press release that we issued this morning, which is posted to Repligen's website and on sec.gov. Adjusted non-GAAP figures in today's report include the following: non-COVID and organic revenue and/or revenue growth, cost of goods sold, gross profit and gross margin; operating expenses, including R&D and SG&A, income from operations and operating margin, tax rate on pretax income, net income, diluted earnings per share, EBITDA, adjusted EBITDA and adjusted EBITDA margin. These adjusted financial measures should not be viewed as an alternative to GAAP measures but are intended to best reflect the performance of our ongoing operations. With that, I'll turn the call over to Olivier.
