2220 GMT - Life360's failure to raise its annual earnings outlook probably sparked the after-hours plunge in the location-app developer's U.S. stock, Jefferies analyst Roger Samuel says. Samuel, who has a "buy" rating on the stock, tells clients that Life360 reported a good set of numbers across users, subscriptions and revenue. However, he points out that the dual-listed company's shares had been on a hot streak heading into the result and thinks that investors could have been anticipating an upgrade to the full-year earnings outlook. Life360's improved revenue guidance now sits above prior consensus, he adds. Samuel has a target price of 30.00 Australian dollars on Life360's ASX-listed stock, which is at A$29.48 ahead of the local open.
