Jan 30 (Reuters) – Deutsche Post’s DHL is considering selling its “last-mile” delivery unit in the United States, a service used by retailers to deliver bulky products to consumers, three sources familiar with the matter told Reuters.

DHL could sell its Exel Direct unit, part of its Exel supply chain in the United States, for about $100 million, one of the three sources said.

The rise of e-commerce has led to a boom in “last-mile” delivery services, used by retailers like Amazon.com Inc to deliver televisions, furniture and other large products that might require installation in a customer’s home.

Exel Direct’s customers include retailers Williams-Sonoma Inc, Sears Holdings Corp and Office Depot Inc , according to its website.

Exel Direct also declined to comment. The unit’s annual revenue is about $150 million and earnings before interest, taxation, depreciation and amortization (EBITDA) is less than $10 million, two of the three sources said.
