Item 1A. Risk Factors

The baseline is this issuer’s latest earlier reporting period of the same form that was filed before the current report. A previous 10-Q is a different quarter, not a year-over-year comparison. Amendments are excluded.

Compared 9 previous paragraphs and 2 current paragraphs.

2 unchanged; 0 reworded; 0 added; 7 removed; 0 previous and 0 current paragraphs rearranged.

Tables are not compared: 0 previous and 0 current tables excluded. Dates, whitespace, punctuation and numbering changes are ignored; changes to financial figures remain significant.

A changed paragraph is not evidence that risk increased or decreased. An unchanged paragraph does not establish that risk stayed the same.

The current filing states there were no material changes to risk factors.

This is the filer’s own statement, not a conclusion from the comparison. Read its qualifications and the report it references.

Current filing’s statement

The matters discussed in this Quarterly Report on Form 10-Q include forward-looking statements that involve risks or uncertainties. These statements are neither promises nor guarantees, but are based on various assumptions by management regarding future circumstances, over many of which Repligen has little or no control. A number of important risks and uncertainties, including those identified under the caption “Risk Factors” in Part I, Item 1A of our Form 10-K for the period ended December 31, 2024 and in subsequent filings, could cause our actual results to differ materially from those in the forward-looking statements. There are no material changes to the risk factors described in our Form 10-K for the period ended December 31, 2024.
