Frequently Asked Questions

What was announced?

PDC Energy will strategically combine with SRC Energy through an all-stock transaction. We are excited about this opportunity to enhance our position as a premier operator in the DJ and Delaware Basins.

Why now?

This announcement is a direct result of your hard work, which continues to drive our success. Over the past few years, we have successfully executed a disciplined operating plan to drive sustainable free cash flow and profitable growth. We have demonstrated a track record of operational excellence, and have taken important steps in both of our core basins to improve drilling and completion efficiency. This transaction will accelerate our strategy and create a best-in-class operator with the size, scale and financial positioning to thrive in today’s market.

Who is SRC?

SRC is a Denver-based oil and gas E&P company with an experienced management and operating team of approximately 150 employees who operate approximately 400 horizontal wells in the Core Wattenberg. SRC has complementary, high-quality assets that are concentrated entirely in Colorado’s Weld County. Importantly, PDC and SRC have similar cultures, as they share our commitment to local communities, environmental responsibility and employee safety.

What are the benefits of the transaction?

Together, we will create a best-in-class operator with enhanced size and scale. Once the transaction is completed, we will be a leading Colorado company and energy producer and the second largest producer in the DJ Basin, while maintaining our strong operating presence in West Texas. The combined company will also have enhanced financial strength and flexibility to capitalize on value-enhancing future growth opportunities.

We believe our companies are a strong cultural fit and that the combination will benefit our stakeholders. By uniting two companies and teams with strong core values and a commitment to responsible and safe operations, we will build on our shared mission to create value for the shareholders of both companies.

What does the transaction mean for PDC employees?

We are confident that employees will benefit from being part of an even stronger company, and better positioned for continued growth and value creation. We look forward to creating exciting new career growth and development opportunities. Of course, we will also continue to prioritize employee health and safety. However, while we work to complete the transaction, PDC and SRC remain separate companies and it is business as usual.

What does this mean for our Delaware Basin operations?

While this combination increases our size and scale in the DJ Basin, our position in the Delaware Basin also remains core, and together, the combined company will be well positioned to deliver significant value. Our teams and assets in the Delaware Basin remain critical to our success.

Who will lead the combined company? Where will the combined company be headquartered?

After the closing of the transaction, PDC’s executive management team will continue to lead the combined company and we will remain headquartered in Denver. The PDC Board will expand to nine directors to include two members of the SRC Board.

Over the coming months, PDC and SRC leadership will work to make the post-closing integration as efficient as possible. We will keep you informed, as appropriate, as other important decisions are made about the future of the combined company.

Will there be any changes to our reporting or organizational structure as a result of this announcement?

It is important to remember that this is just the first step, and the transaction will not be completed until the fourth quarter of this year. In the interim, it remains business as usual and there are no changes to the way we operate. We are committed to conducting a thoughtful integration planning process and will continue to keep you updated as that develops.

Will there be workforce reductions at PDC and/or SRC?

While we expect new career growth and development opportunities for employees as part of a bigger company, in any combination of two companies in the same industry, there will be some overlap. We have only just announced this transaction and there are still many details yet to be worked out as part of the integration planning process.

One of the reasons we are so excited to bring our companies together is that we are uniting two teams with strong values and a shared commitment to responsible and safe operations. We are committed to transparency and to making the transition as smooth as possible as we bring our companies together.

What does this mean for our business partners?

We are confident that this transaction will benefit our stakeholders, including our business partners. We remain focused on maintaining our strong commercial relationships and will continue to work with suppliers and other business partners as we always have.

How soon can PDC employees interact with SRC employees?

Please do not engage with SRC employees regarding this transaction unless you are directed to do so. Until the transaction closes, both companies will continue to operate independently.

When will the transaction be completed? What can we expect between now and the close of the transaction?

We expect the transaction to close in the fourth quarter of 2019, subject to customary closing conditions and regulatory and shareholder approvals. Importantly, until the transaction closes, PDC and SRC will continue to operate as independent companies

and it will be business as usual. We will continue to provide you with updates as additional details are available.
