Instagram: Facebook's Next Big Money Maker

NEW YORK (TheStreet) -- Facebook shares have been on something of a roll in recent months, ever since the company's second-quarter earnings showcased the mobile strength everyone was hoping for. Now, Wall Street analysts are falling over themselves to raise their price targets, with one analyst believing shares have another run of 20+% in them.

Deutsche Bank analyst Ross Sandler raised his price target to $62 from $43, keeping his "buy" rating on shares, as he believes 2015 estimates are too conservative, even before factoring in the possibility that Instagram, which Facebook bought for roughly $730 million, generates $1.8 billion in revenue in fiscal 2015.

Sandler noted that Instagram could see a mid- first-quarter 2014 ad launch, which could wind up being worth an additional 15% revenue to Facebook in 2015.

When Instagram unveiled that it was bringing video to its platform, as it competes with Twitter's Vine product, the company noted it had more than 130 million monthly active users.

On Facebook's second-quarter earnings call, CEO Mark Zuckerberg talked up the power of Instagram as a business.

"There are so many directions to expand this in that we think that the right focus for now is to continue just focusing on increasing the footprint of Instagram," Zuckerberg said on the call. "And when the right time comes then we'll think about doing advertising as well, but I think that's going to be a really big opportunity."

Outside of Instagram and its incredible potential, Sandler noted that mobile ads are significantly underappreciated by Wall Street.

"Mobile users in US and UK are growing at ~20% Y/Y, while ROW is growing at 60%, which we view as a proxy for inventory creation," Sandler wrote in the report. "Further, FB stated that ad load is 1-ad-per-20-newsfeed-stories globally in 2Q, the ceiling likely closer to 1-per-5, suggesting a growing opportunity. Looking ahead, increasing the selection of ads in the system, improving the ad products, and layering in better targeting should drive higher monetization."

Sandler noted that only 6% of the mobile impressions were responsible for the $656 million in mobile revenue last quarter. That suggests that Facebook has "ample runway ahead," as it continues to improve its ad impressions, delivering a better return on investment (ROI) to advertisers.
