Dear Analysts and Shareholders,

Today, we filed our preliminary proxy statement / prospectus regarding the actions announced last week on domicile, share consolidation and re-brand. We are providing this summary document and a few slides to further illuminate how these actions should improve our valuation over time. If we can provide any additional details or answer questions, please let us know.

Establishing domicile in the United States is expected to expose our Company to significantly larger, and growing, pools of capital. Our actions are not about politics or pipelines but rather address the significant valuation gap between our Company and our key U.S. peers, which we believe is attributable in part to our current Canadian domicile. This hinders our competitiveness with peers, and we believe directly weighs on share demand. This action can be done at minimal cost to the Company, provides access to an U.S. equity market over 15x in size and is a pre-requisite for numerous pools of capital located in the U.S.

30%	MRO	24%	PXD
30%	DVN	24%	CLR
28%	APA	22%	EOG
27%	NBL

+20% of passive ownership could expose ECA to >$1B of additional demand

Following the domicile move to the U.S., which we believe will be approved in early 2020, our head office will be in Denver, Colorado with incorporation in Delaware. This action should lead to rebalances in index ownership from Canada to the U.S. Once leveled, we believe these adjustments will bring in net positive share demand. This adjustment process is the primary reason for our actions as substantially more funds are expected to flow into the stock than will exit. For example, today Encana is only held by 58 of the top 10 institutional money manager index funds. In contrast, our peers are held by 127 on average. We believe this fund exposure disconnect weighs on the demand for Encana’s shares and can be recalibrated with a U.S. domicile.

S&P Index Positioning Illustration

Though Encana may not qualify for the S&P 500 today due to its Market Value, ECA is actually larger than one current E&P constituent in the S&P 500. Based on Market Value, we would however fit squarely into the S&P 400 Mid Cap index which provides access to numerous secondary indices and passive investment vehicles. Once included we would be the largest E&P by more than $1B of Market Value.

Key Index Family Considerations

We firmly believe the move to U.S. domicile will be positive for our shareholders. Very few times in a company’s existence can it easily act on such a clear value disconnect. This time next year, subject to the discretion of the indices, we would expect to be eligible for inclusion in the S&P 400 & 1500 indices, Russell 1000 & 3000 indices, CRSP Total Market & Small-Cap indices and numerous applicable secondary indices such as the S&P XOP.

Conclusion

We are focused on creating value for our shareholders. Our early 2020 special meeting covering the U.S. domicile, rebrand and 1-for-5 share consolidation highlights initiatives that we believe will be accretive to our valuation and add value for ALL shareholders. We have a long history in Canada and remain committed to our Canadian roots. We will continue our dual TSX & NYSE listings and maintain a substantial Canadian asset and staffing presence. A significant portion of our Executive Leadership Team is located in Canada today and no jobs will be lost or moved in any of our offices due to these actions. If there are any questions, please refer to the Shareholder FAQs on our website and the preliminary proxy statement / prospectus. As always, we are available by phone at (281) 210-5110 or (403) 645-3550.
