Joint Integration Update Letter
Whiting and Oasis Teams,
We would like to begin by thanking you for your unwavering dedication to our companies and commitment to operating safely and with integrity. Leadership from both companies has valued the opportunity to meet with many of you, and we sincerely appreciate the ideas, suggestions, and feedback you have shared.
We are pleased to share a few additional updates on our pending merger and ongoing integration planning:
HSR Waiting Period Expiration & Integration Planning Progress
On Monday, April 18, the statutory waiting period under the HSR Act expired for the transaction. Completion of the HSR process is an important step in closing the merger. This positions us to move from the Setup phase of integration to the Design & Planning phase.
On April 25th, as part of the Design & Planning phase, we will set up various discipline-based Integration Planning Teams (IPTs) across the organizations. These IPTs will help us:
| • | | Align on processes, information flow and systems, including risk identification and mitigation |
| • | | Outline detailed plans to ensure business continuity upon close |
| • | | Identify pathways to eventually merge tasks that will run in parallel for a period after close |
| • | | Develop plans to achieve synergies |
| • | | Assist with future state organization design for respective disciplines |
| • | | Coordinate with other discipline leads as required on interdependencies |
A high-level outline of the Integration team structure and the teammates from each company that are providing support can be viewed here [add link]. We are thankful to have this added expertise, fully recognizing these individuals still have job duties to perform. Please lend your support to them and refrain from asking them to share information ahead of the process.
Introduction Meetings with Senior Leaders
Senior leaders from both companies have held informal “get to know you” sessions with some teams. We will continue these sessions over the coming weeks. These meetings are meant to 1) facilitate introductions, and 2) provide a high-level overview of a team’s primary tasks, processes and systems.
Positive Investor Feedback
Many investors in both companies have expressed support for the merger. Investors recognize that the combination of Oasis and Whiting will best position the combined company for near- and long-term success, and we’re pleased that they share our confidence and excitement.
