    Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

    On September 2, 2025, Repligen Corporation (the “Company”) announced that it was appointing Violetta Hughes as the Company’s Chief Accounting Officer, effective September 1, 2025 (the “Effective Date”), in an effort to build a more robust infrastructure at the Company for financial reporting and oversight of matters related to the Sarbanes–Oxley Act. In this role, Ms. Hughes will become the Company’s principal accounting officer, replacing Jason K. Garland, who will continue to serve as the Company’s Chief Financial Officer with more of his time dedicated to corporate strategy, financial planning and analysis, capital markets, and driving growth.

    Ms. Hughes, age 53, is a seasoned finance executive with deep expertise in financial controllership, operational finance, and global team leadership across diverse industries including life sciences, medical technology and pharmaceuticals. Ms. Hughes brings over 25 years of experience and a disciplined approach to financial governance with a strong track record of leading through change, including driving improvements in financial transparency, implementing SOX compliance frameworks, and partnering with business leaders to support strategic decision-making. Prior to joining the Company, from January 2023 to August 2025, Ms. Hughes served as VP and Chief Accounting Officer at Azenta, Inc. (NASDAQ: AZTA), a leading provider of life sciences solutions worldwide, where she led enterprise-wide initiatives to modernize financial systems, streamline close processes, and improve SOX compliance. From December 2020 to December 2022, Ms. Hughes served as SVP and Chief Accounting Officer at Akebia Therapeutics, Inc. (NASDAQ: AKBA), a fully-integrated biopharmaceutical company focusing on kidney diseases. Prior to AKBA, from December 2016 to November 2020, Ms. Hughes served as SVP of Accounting, Corporate Controller at AMAG Pharmaceuticals, Inc. (NASDAQ: AMAG), which was a publicly-traded pharmaceutical company developing products treating iron deficiency anemia in adults, until its acquisition by Covis Pharma in November 2020.

    Ms. Hughes holds a B.S. in Accounting from the University of Massachusetts Lowell.

    In connection with Ms. Hughes’ appointment, the Compensation Committee of the Board (the “Compensation Committee”) approved an annual base salary of $395,000, effective as of the Effective Date, and a one-time signing bonus of $150,000. Ms. Hughes will also be eligible for a target annual performance bonus of up to 50% of her base salary. In addition, Ms. Hughes’ offer letter provides for an annual equity award worth an aggregate amount of $750,000, $500,000 of which will be granted in the form of restricted stock units and $250,000 of which will be granted in the form of options to purchase the Company’s common stock, subject to the approval of the Compensation Committee and effective as of the Effective Date, which will vest in equal annual installments on each of the first, second, third, fourth and fifth anniversaries of the Effective Date, subject to Ms. Hughes’ continued employment with the Company through the applicable vesting date, and that she will be eligible to participate in all customary employee benefit plans or programs generally available to the Company’s full-time employees.

    There are no arrangements or understandings between Ms. Hughes and any other person pursuant to which she was selected as an officer, no family relationships between Ms. Hughes and any other executive officer or director of the Company, and no related party transactions within the meaning of Item 404(a) of Regulation S-K between Ms. Hughes and the Company.
