On October 14, 2025, Guardian Pharmacy Services, Inc.

Pursuant to these agreements, the Lock-UpHolders have agreed that, during the period from October 19, 2025 (the expiration date for existing lock-upagreements with holders for substantially the same number of shares of the Company's common stock) through June 30, 2026 (the "Lock-UpPeriod"), they will not offer, sell, distribute or otherwise dispose of or transfer any shares of the Company's common stock without the prior written consent of the Company. The lock-upagreements impose transfer restrictions on 17,188,059 outstanding shares of Class A common stock held by the Lock-UpHolders, as well as 12,759,054 additional shares of Class A common stock issuable to the Lock-UpHolders on March 28, 2026 upon the automatic conversion of an equal number of outstanding shares of Class B common stock held by them. The Lock-UpPeriod with respect to any Lock-UpHolder may be extended by mutual written agreement of the Company and the respective Lock-UpHolder.

As of September 30, 2025, the Company had outstanding 36,253,744 shares of Class A common stock and 27,066,890 shares of Class B common stock.
