**To:** Verona Pharma employees

**From:** Verona SVP, HR, Ostra Jewell

**Date:** September 10, 2025

**Subject:** Recap from Verona Employee Town Hall with Merck

Team Verona,

Thank you to all who joined us for the **Verona Employee Town Hall with Merck** last week! I hope you found it valuable and informative as we continue our integration planning.

During the meeting, Merck's leaders provided updates on retention agreements and the integration timeline, and I shared more information on severance. If you were unable to attend or should you want a recap, below is a summary of key takeaways and attached are the slides.

**Key Takeaways** 

**Overall Tone:** Merck values Verona's culture and expertise, wants to minimize business disruption, and offers expanded resources and career opportunities.

**Retention Agreements** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. All employees (with the exception of select executives) were offered a retention agreement on August 29. Your
retention acceptance is due back to me no later than September 19.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. Signing preserves eligibility for retention bonuses; not signing does not change employment but forfeits the
retention benefit.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. Retention periods define the timeframe Merck needs employees during integration; accepting a permanent Merck
role during retention does not forfeit the retention payment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4. Timing of retention periods can be adjusted by mutual agreement.

**Severance** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. All employees are eligible for a change-in-control severance package as long as you complete knowledge transfer and you incur a qualifying termination of employment (and aren't terminated for
cause or resign).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. If offered a full-time Merck role and you decline it, you remain eligible for severance at the end of your
retention.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. Minimum severance increased to six months (previously three months for senior manager and below; directors had
six months).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4. See slide 11 for more information.

**Integration Timeline** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. We are currently in the pre-closing quiet period, so certain activities
and communications are limited by regulations until close.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5. Close is the completion of the deal, when Verona Pharma becomes a wholly owned subsidiary of Merck; Day One is
typically the first business day after close.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. Minimal business disruption is expected on Day One. Primary goals are business continuity and maintaining
commercial/pipeline momentum.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6. The preliminary date for many integration milestones is April 1, 2026 (specifically, transition to Merck
payroll, benefits, financial and HR systems, and distribution of Merck laptops). Merck is still developing the integration plan so this date is not yet final.

**Next Steps & Support** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. Review and sign your retention agreement and send to me by the September 19 deadline.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. Complete the short "Day-in-the-Life" tool (for those who have been asked to) and return to me no later than September 19.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. Verona leadership remains the primary point of contact during the pre-closing quiet period; Merck integration team will regularly check in.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4. The Employee Resource Guide, which was first provided with your retention agreements, will continue to be
updated with FAQs and answers.

Thanks as always for your engagement, and please continue to reach out to me with any questions.
