Uber is giving a look under the hood of its business to its hotly anticipated debut on the stock market in the lead-up.

Documents released Thursday offered the view of the world’s largest ride-hailing support . The unveiling comes four weeks later its first step was taken by Uber a confidential filing.

The gigantic filing reveals Uber has been producing the robust earnings growth that attracts investors, but racked up nearly $8 billion in losses over its 10 years in life, which mirrors the identical trend hard Lyft, Uber’s most important competition in the U.S.

The company posted a gain of $997 million but that doesn’t imply its ride-hailing service started to earn money — far from it. The positive result stemmed from a windfall which Uber generated from the selling of its operations in Russia and Southeast Asia.

Reaching profitability has proven to be a struggle for the two Lyft and Uber. Drivers that are paying is a massive expense, and also Uber rivalry with Lyft for customers has led both companies to offer rides. Passengers for both businesses whine of wages that are decreasing, and they can easily change between platforms, making it hard for either company maintain fares cheap for passengers and to further reduce driver expenses.

That history can force Uber to eventually increase its costs that are ride-hailing unless it can reduce its costs by shifting to driverless automobiles or expand to other markets and lines of industry.

Lyft’s inventory now is currently hovering around $61down from its IPO price of $72.

The beginning may have prompted Uber to tamp down its IPO ambitions. That’s below estimates of about $120 billion.

Uber was valued at $72 billion, according to SharesPost analyst Alejandro Ortiz.

The investment bankers handling Uber’s IPO are expected to reveal a pricing scope for Uber’s shares later this month before going into a so-called road series designed to drum up interest in the IPO among institutional investors who will be given the first chance to buy the stock before it starts trading on the New York Stock Exchange next month.

The market worth of Uber will be determined by the amounts.

In the long run, Uber is widely predicted to be the tech IPO since Chinese e-commerce giant. And it’s likely to be the largest among U.S. tech firms because Facebook took its bow on Wall Street seven years back in a time when most people had never considered using a program in their smartphone to muster a ride from strangers driving their own automobiles.

Uber started in 2009 as a black vehicle service where customers are able to hail professional motorists with a few taps on a smartphone, as UberCab. Its name shortened in 2010 to Uber, distancing itself from the taxicab business, which has been criticized the firm for confronting regulation that was less than the cab industry.

The business operates in 65 countries and has finished 10 billion excursions worldwide.

While offering different strategies to get about with scooters and bikes uber is also growing in markets such as freight and food delivery.

However, Uber faces challenges that Lyft does not due to a string of revelations that sullied its reputation among consumers. The setbacks have included rampant internal sexual harassment and allegations it stole vehicle engineering.

The blowback from the problems helped Lyft pickup soil in the U.S. and contributed to the ouster of both Uber co-founder Travis Kalanick CEO in 2017. Now it’ll be up Dara Khosrowshahi, to Kalanick’s successor, to convince investors that Uber has cleaned up its act and merits a market value higher than General Motors and Ford Motor combined.
