Precision Drilling Corporation

Notice-and-Access Notification to Registered Shareholders

You are receiving this notification as Precision Drilling Corporation (Precision) has elected to utilize the notice-and-access provisions adopted by the Canadian Securities Administrators (Notice-and-Access) for delivery of its information circular and related proxy materials, as well as Precision's 2025 Annual Report (which includes its audited consolidated financial statements for the fiscal year ended December 31, 2025 and the related management's discussion and analysis) (collectively, the Meeting Materials) to its shareholders who hold their Precision common shares in their own name (the Registered Shareholders). Precision will not utilize Notice-and-Access with respect to the mailing of the Meeting Materials to Registered Shareholders who have standing instructions, or have otherwise requested, to receive paper copies of materials. Rather, such shareholders will receive paper copies of the Meeting Materials.

The use of this alternative means of delivery is more environmentally friendly as it helps reduce paper use and also reduces the cost of printing and mailing materials to shareholders.

Please review the information circular before voting.

You are invited to our 2026 Annual Meeting of Shareholders:
