## Exhibit 99.1

**EXHIBIT 99.1**

**Galapagos Announces Appointment of Fred Blakeslee as General Counsel**

**Mechelen, Belgium; October 16, 2025, 22:01 CET; Galapagos NV (Euronext & NASDAQ: GLPG) today announced the appointment of Mr. Fred Blakeslee as Executive Vice President and General Counsel effective October 16, 2025. Blakeslee is succeeding Ms. Valeria Cnossen, who will leave the Company after a short transition period.** 

"We are very pleased to welcome Fred to the executive team," said Henry Gosebruch, CEO of Galapagos. "He brings a unique combination of top-tier legal expertise, global business transaction experience, and deep strategic understanding of the biopharma ecosystem. His proven track record of negotiating complex, high-impact partnerships and acquisitions, and fostering cross-functional collaboration, along with his strong commitment to patient-centric innovation, will be invaluable as we progress on our transformation journey."

Gosebruch added, "On behalf of the entire leadership team and Board of Directors, I want to thank Valeria for her strong leadership, dedication and valuable contributions over the past three years. We wish her all the best in her future endeavors."

Blakeslee most recently served as Vice President, Transactions, Legal at AbbVie, where he led global legal teams supporting business development and alliance management in complex mergers, acquisitions, licensing, and collaborations. His work included AbbVie's landmark $63 billion acquisition of Allergan PLC, as well as numerous high-profile partnerships and transactions with companies such as Boehringer Ingelheim, ImmunoGen, and Genmab.

He began his career at Kirkland & Ellis LLP and later held senior roles at leading law firms, advising on private equity, corporate, and securities transactions across the biopharmaceutical and other industries. Blakeslee earned his Juris Doctor, *cum laude*, from Northwestern University School of Law and holds dual Bachelor's degrees in Mathematics and Political Science, *magna cum laude*, from The Ohio State University. Based in Chicago, Illinois, Blakeslee also speaks French.

"I am honored and excited to join Galapagos at a pivotal time in the Company's transformation," said Blakeslee. "I look forward to working alongside Henry and the talented team to shape Galapagos' next chapter, drive strategic growth while creating shareholder value, and bring innovations to patients through transformational business development transactions."
