Dear [INVESTOR NAME],

I am pleased to share the exciting and important news that yesterday, 29 April 2018, Prologis announced a deal to acquire DCT Industrial Trust. You can read more about the transaction in the attached press release.

This deal is about strategic fit and scale. Prologis has long considered DCT’s portfolio to be the most complementary to our own, both in terms of product quality and market position.

This transaction presented a rare opportunity to acquire one of the highest quality industrial portfolios in the U.S. In buying DCT, we will deepen our presence in core, high-growth markets including Southern California, the San Francisco Bay Area, New York/New Jersey, Seattle and South Florida.

Because DCT adds to our scale and reach, the transaction creates additional opportunities to better serve our customers. It allows us to provide our customers with greater market insights and even more options to access high-quality logistics real estate in the best and most strategic locations.

The proposed transaction is scheduled to close in the third quarter of 2018, and for now, it’s business as usual at Prologis. We will continue delivery of the quality services our customers and investors have come to expect from us, without interruption, and will keep you informed of our progress. Should you have any questions or concerns, please feel free to contact me at [EMAIL, PHONE NUMBER].

Sincerely,

[SIGNATURE]
