May 4 (Reuters) - Lyft Inc on Tuesday posted significantly lower losses than expected and reiterated its goal to be profitable on an adjusted basis in the third quarter thanks to continued cost cuts that allow the company to earn more per ride. Lyft reported an adjusted $73 million first-quarter loss before interest, taxes, depreciation and amortization - a metric that excludes more than $300 million in one-time costs, including stock-based compensation. That is significantly narrower than the $144 million loss analysts had projected on average, according to Refinitiv data. The results come as Lyft emerges from more than a year of pandemic-related restrictions during which ridership and revenue plummeted. But as COVID-19 vaccination rates increase across the United States, Lyft expects riders and drivers to return to the platform in greater numbers in the coming months, allowing the company to take advantage of its leaner cost structure and make more money per ride, Lyft President John Zimmer told Reuters in an interview. Zimmer played down the threat of federal regulation that would turn most ride-hail and food-delivery workers, who currently are independent contractors, into employees. The company reaffirmed its goal to be profitable on the adjusted EBITDA metric in the third quarter of this year, a target it recently pulled forward by three months when it announced the sale of its self-driving technology business. Lyft’s larger rival, Uber Technologies Inc, has projected profitability on an adjusted basis by the end of 2021. Uber is scheduled to report results on Wednesday afternoon. On a net basis, Lyft’s loss widened to around $427 million, driven by high stock-based compensation costs as the result of the company’s public listing more than two years ago. Asked whether Lyft would target net profits, Zimmer said the company in the near-term remained focused on its adjusted EBITDA profitability metric. At $609 million, first-quarter revenue also outstripped average Wall Street expectations for $559 million. Lyft has drastically slashed costs during the pandemic when ridership plummeted and it continued to cut expenses in the first three months of 2021, even as riders gradually returned. Total costs in the first quarter decreased by more than $344 million and overall, Lyft has slashed nearly $2.5 billion in costs since the beginning of last year. Zimmer said the company also expected incentive spending for drivers to decrease in the coming months. Lyft and Uber currently boost earnings of drivers to bring them back on the road as demand temporarily outstrips supply, which has resulted in longer wait times and higher prices in some cities. “We expect driver supply to improve over the coming months as drivers see that demand has returned to the platform,” Zimmer said. The number of active riders in the first quarter rose more than 7% from the last three months of 2020, but ridership still remains around 36% below last year. But as business gradually returns, Lyft and its gig-economy peers in the ride-hail and food-delivery industry face regulatory pressure under the new administration of U.S. President Joe Biden, who campaigned on the promise of delivering benefits to gig workers by turning them into employees. The shares of the companies took a tumble last week when U.S. Labor Secretary Marty Walsh told Reuters in an interview that “a lot of gig workers should be classified as employees.” The companies rely on low-cost flexible workers and say their services would become unavailable if workers were reclassified as employees. They say surveys show the majority of their workers do not want to be employees. Zimmer on Tuesday played down the risks of federal regulation, saying a labor bill supported by U.S. Democrats faced tough odds of passing in Congress. He said the company instead was focused on adopting compromise regulation on the state and local levels, modeled after a November gig industry-sponsored California ballot measure that cemented ride-hail and food delivery workers’ status as contractors, but provided them with some benefits. “I honestly believe that we will continue to see common-ground, practical solutions that balance independence for drivers ... with additional benefits,” Zimmer said, adding that he thinks the federal government will eventually pass guidance that makes it easier for states to adopt compromise regulation.
