Interested in owning BlackBerry (BlackBerry Stock Quote, Chart, News, Analysts: TSX:BB)? Portfolio manager Teal Linde advises putting the stock in the \u201cHold\u201d category for the time being, at least until the sightlines clear up for its connected car business. As 2020 draws to a close, BlackBerry finally climbed into positive territory for the year, with the market seemingly more excited about the company since it announced a partnership with Amazon Web Services. That came earlier this month, with the two tech companies revealing a collaboration on BlackBerry\u2019s Intelligent Vehicle Data Program, IVY, which is being touted as the future for in-vehicle applications, data collection and monetization. BlackBerry\u2019s share priced popped 30 per cent on the news, a multi-year co-development and co-marketing agreement which BlackBerry CEO John Chen called a rarity in the business. \u201cEach side contributes the key capabilities required,\u201d said Chen in BlackBerry\u2019s fiscal third quarter earnings call on December 17. \u201cOn the BlackBerry side, BlackBerry QNX brings over 20 years of auto industry experience, as well as relationship, as well as a huge footprint of over 175 million cars.\u201d \u201cWe are a trusted leader with a deep knowledge of automotive safety and security software system. AWS is the world's largest cloud provider with advanced developer community and outstanding expertise in consumer experience, interfaces, as well as IoT. Combined, we're able to provide a full end-to-end platform,\u201d Chen said. \u201cWe expect an ecosystem of apps and services developed on the BlackBerry IVY platform over time.\u201d Linde says the attraction for investors definitely lies in BlackBerry\u2019s connected car business. \u201cBlackBerry is basically in two businesses: they\u2019re in data security for companies and also in the automobile sector where they\u2019re trying to basically establish an operating system for the connected car,\u201d said Linde, manager of Linde Equity Fund, who spoke on BNN Bloomberg on Monday. \u201cOn the data security side of the business, that\u2019s a tough business. They\u2019re competing against Microsoft, which has products that are virtually offered for free. And Palo Alto Networks is a fierce competitor \u2014this is a company that when they announce their quarterly results they talk about the business that they\u2019ve taken away from their competitors.\u201d \u201cBut it\u2019s the connected car side of the business which is more interesting, where if can grow that business and have an operating system that is in all the new cars that are made, that has upside,\u201d Linde said. Soon after the AWS announcement, BlackBerry\u2019s stock drifted lower following its fiscal third quarter 2021 earnings report, delivered on December 17. There, BB\u2019s adjusted revenue was $224 million, down from $280 million a year earlier while non-GAAP adjusted earnings were $0.02 per share compared to $0.03 per share a year earlier. Both top and bottom line numbers were better than expected according to analysts\u2019 consensus estimates, but management\u2019s guidance for the full fiscal 2021 placed revenue at about $950 million, which would be lower than fiscal 2020\u2019s $1,040-million in revenue. In the company\u2019s key software and services segment, BlackBerry saw revenue fall to $162 million from $185 million on a GAAP basis, while licensing revenue fell to $56 million from $82 million. Writing in a client update on December 18, RBC Capital analyst maintained his \u201cHold\u201d rating and $7.50 per share target on BlackBerry, saying the company\u2019s growth prospects are still unproven. \u201cThe investor debate on BlackBerry stems from the company\u2019s future opportunity compared to its current momentum,\u201d Treiber wrote, as reported by Tipranks. \u201cPending stronger growth or better visibility to BlackBerry\u2019s emerging opportunities, we see the valuation re-rating in BlackBerry\u2019s shares sustained at current levels\u2026 Our target multiple is justified below peers (at 7.1x), given BlackBerry\u2019s lower growth.\u201d Linde would appear to agree with the sentiment. \u201cBlackBerry is apparently earning about $4 per car and they want to have a business model in place where they can earn $20 per vehicle, but it\u2019s going to take time,\u201d Linde said. \u201cIt\u2019s still in the early stages, so we\u2019re just sort of watching it and waiting.\u201d \u201cIt\u2019s kind of a Hold if you\u2019re really patient,\u201d Linde said. On the rest of the fiscal year for BlackBerry, Chen has said revenue will get back to pre-pandemic levels as the auto sector starts to recover. \u201cWe continue to expect total company revenue for the year to be around $950 million, as we indicated last quarter. We expect licensing revenue will finish the fiscal year a little stronger than previously indicated. We expect revenue for to continue to grow sequentially in the fourth quarter and \u2026 to return to its normal run rate early next fiscal year,\u201d Chen said in the third quarter conference call. \u201c, we continued to make good progress. We delivered solid financials as per our outlook. We have developed exciting new business model, the recurring revenue model for QNX, as well as partnership, which I outlined, and we delivered industry-leading products as per our road map,\u201d Chen said.
