 Shares of Arlo Technologies Inc. rallied more than 18 in the extended session Wednesday after the maker of security cameras, video doorbells, and other home security electronics reported a narrower second-quarter loss and sales rose above expectations. Arlo said it lost 29 million, or 38 cents a share, in the quarter, compared with a loss of 34 million, or 45 cents a share in the year-ago period. Adjusted for one-time items, Arlo lost 31 cents a share, compared with a loss of 36 cents a share a year ago. Revenue dropped 20 to 67 million, the company said. Analysts polled by FactSet had expected an adjusted loss of 41 cents a share on sales of 55 million. Arlo guided for revenue between 85 million and 95 million for the third quarter, and a GAAP net loss between 41 cents a share to 32 cents a share for the quarter. It said that because of the pandemic it was not providing 2020 guidance. I believe the second quarter marks an inflection point in our subscription business and expect this momentum to continue, Chief Executive Matthew McRae said in a statement. Shares of Arlo ended the regular trading day down 4.6.
