fuboTV's (FUBO -2.02%) stock has fallen off a cliff over the last year, mainly due to investors worrying about its profitability in this rising interest rate market. fuboTV didn't do itself any favors when advertising, its only source of high-margin revenue, underwhelmed in its first-quarter earnings report. The advertising underperformance has some investors wondering whether the results were only an aberration or whether it foreshadows significant problems moving forward. Here's two reasons why investors should be concerned with fuboTV's ad business.

1. fuboTV's ad business is dealing with the initial impact of inflation

In early May, fuboTV's ad business produced disappointing results for the first quarter ended March 31. fuboTV management blamed reduced TV ad spending from consumer product goods (CPG), finance, and technology companies for the poor results, which some experts believe is a reaction to inflation and supply chain disruptions. As a result, fuboTV's advertising Average Revenue Per User (ARPU) declined 4.5% year-over-year in the first quarter of 2022 and negatively impacted fuboTV's contribution margin, which fuboTV uses to measure its progress towards profitability. As a result of fuboTV's profitability setback, the stock dropped over 20% the day after fuboTV released earnings.

Although experts expect ad spending in the U.S. ad market to increase by 14% in 2022, elevated inflation and supply chain issues in the automotive, CPG, and electronics could cause ad growth to continue to underperform. Consequently, the risk of poor economic conditions persisting is something an investor must accept when investing in fuboTV.

2. fuboTV has yet to show any competitive advantages in advertising

First, the streaming ad market is highly competitive, and fuboTV has little to differentiate itself from YouTubeTV or Hulu Live.

Second, fuboTV is still only a relatively small player in an ad industry dominated by much larger platforms -- which translates into fuboTV currently lacking the heft to charge advertisers higher prices.

Third, marketers tend only to pay up to advertise on platforms that have modern ad targeting technology and can provide good analytical tools for showing ad effectiveness. Unfortunately, fuboTV recently announced a delay in rolling out improvements in its ad technology -- meaning fuboTV currently cannot drive ad prices up. fuboTV blames the delay on difficulties in hiring people with the expertise to build advertising software. Consequently, fuboTV is now trying to create its advertising capabilities with in-house employees -- one reason for being behind schedule. Whether fuboTV can get its technology up to the level of its larger competitors if the inability to hire advertising experts persists is a critical question. And a reason why the announcement of delays in rolling its ad network out fails to inspire confidence that fuboTV can match its competitors any time soon.

Reasons why fuboTV's ad business can still succeed

First, fuboTV expects a rising tide of advertisers to shift ad budgets from traditional cable TV to streaming platforms.  As of the fourth quarter of 2021, viewers in the prime advertising demographic of 18- 49 spent 45% of their TV time streaming. However, advertisers have only shifted 18% of their ad budgets to streaming. At some point, the large gap between streaming consumers and advertisers should close.

Second, despite delays, fuboTV plans to have its ad technology available to roll out at the end of the second quarter. fuboTV's new technology will enable it to sell its ad space more effectively on different ad exchange platforms -- which should improve what fuboTV can charge advertisers in the second half of 2022.

Third, up until recently, fuboTV has focused more on increasing subscribers rather than building up advertising, but that has now changed. Although fuboTV had recent difficulties in hiring, they have now built up its ad tech team from six to 17 in the last 18 months. In addition, fuboTV is still filling out its sales team, which currently stands at only four people. 

Keep A Close Eye Out

fuboTV management has targeted positive cash flow and Adjusted EBITDA by 2025, and growing its high margin advertising revenue is fuboTV's best chance of getting there. While the advertising opportunity has much promise, fuboTV is only at the early stages of scaling the ad business in a challenging market. If you decide to invest in this high-growth streaming company, you would be wise to monitor fuboTV's advertising ARPU for signs of progress towards its goal of $10 to $15.
