For purposes of vesting, participants generally earn a "year of service" for vesting purposes for each year you remain continuously employed with the IQVIA or a Participating Employer through your next employment anniversary date provided you are an eligible employee.

Note: Legacy Participants in the IMS 401(k) and Quintiles 401(k) Plans retained the vesting percentages and are generally subject to the same vesting rules in place under their respective plans at the time of the plan merger on January 1, 2018. In addition, legacy participants under the IMS 401(k) and Quintiles 401(k) Plans may receive credit for prior service with various predecessor employers and/or Participating Employers that were acquired by the IMS or Quintiles' groups prior to the IQVIA plan merger and have had that prior credit carried forward within the IQVIA 401(k) Plan. If you have questions regarding the calculation of vesting credit under predecessor employers, please contact the Plan Administrator.

The vesting methodology under the legacy Quintiles 401(k) Plan was previously amended effective January 1, 2014 to provide for vesting using the "elapsed time" method currently in use. (For legacy Quintiles 401(k) Participants hired on or after January 1, 2006 but prior to 2014, a "year of service" was earned each plan year in which the Participant worked at least 1,000 hours during a plan year applying the equivalency method on a weekly basis.)

Note: All legacy Quintiles Participants hired prior to 2006 are fully vested with respect to Company Matching Contributions. Legacy IMS Participants generally had service credited based on a similar "elapsed time" method using a monthly equivalency method that has been carried forward to the IQVIA 401(k) Plan. If you should have any questions regarding the historic crediting of your service under the merged IQVIA 401(k) Plan, please contact the Plan Administrator.

Under the merged IQVIA 401(k) Plan, the matching contributions of all Participants (including legacy IMS 401(k) Participants) are subject to a 2-year graduated vesting schedule using the elapsed time method. Accordingly, all Participants are generally entitled to 50% vesting after 1 Year of Service and 100% vesting after 2 Years of Service as illustrated in the following table:

(Important note: This change may provide accelerated vesting for legacy IMS Participants who were previously subject to a 3-year cliff vesting requirement. For example, if you were a legacy IMS Participant who worked for IMS for just over 1 year at the time of the plan merger, you will now be eligible for 50% vesting in your matching contributions with the remaining 50% vesting after 2 Years of Service when you previously would have had to accrue 3 Years of Service in order to vest in any portion of your matching contribution.)

For discretionary profit sharing contributions or other non-elective contributions, as applicable, Participants are subject to a graduated, six-year vesting schedule as follows:

As of September 25, 2003, participants were fully vested in all other legacy Quintiles 401(k) Plan accounts other than matching contribution and profit sharing accounts. In addition, all legacy Quintiles 401(k) Participants hired prior to 2006 are fully vested in their matching contribution accounts under the Plan.
