Factbox: How Uber and Lyft compare on key financial metrics

Uber Technologies Inc's initial public offering filing on Thursday contains data that will be key to selling itself to investors. The share sale follows a public offering by rival ride-sharing service Lyft Inc last month, whose shares have dropped to about $61 from an IPO price of $72.

Here are how the two companies compare on key metrics from Uber's filing:

REVENUE

Uber had $11.3 billion in 2018 vs Lyft $2.2 billion.

Uber's growth has been slowing relative to Lyft due to scandals and aggressive discounting by Lyft.

Lyft's revenue more than doubled between 2017 and 2018 while Uber's grew around 41 percent.

MARKET SHARE

Uber has lost market share but remains the leader.

Uber has 65 percent share in North America while Lyft says it has 39 percent in the United States.

ADJUSTED EBITDA

Both Uber and Lyft lose money though Uber has trimmed its losses in recent years.

Uber's adjusted loss before interest, taxes, depreciation and amortisation was just over $1.8 billion in 2018 compared to $2.6 billion in 2017.

Lyft lost $950 million in 2018 on the same basis.

MONTHLY ACTIVE USERS

Uber has 91 million monthly active users compared to Lyft's 18.6 million.

Uber's number includes customers of additional services beyond ride sharing.
