Shares of Meta Platforms (META 0.84%) have crushed the broader market handsomely in the past year with impressive gains of 145%, driven by robust growth in its top and bottom lines. It looks like its eye-popping rally is here to stay following its latest earnings report.

Meta Platforms released its fourth-quarter 2023 results on Feb. 1. Shares of the company jumped 20% the following day thanks to its better-than-expected numbers and guidance. The good part is that Meta remains affordable despite the stock's big jump in the past year, which is why investors who haven't bought this tech giant yet should consider buying it hand over fist right away. Let's look at the reasons why.

Meta Platforms is becoming a bigger player in the digital ad market

Meta Platforms reported Q4 revenue of $40.1 billion, an increase of 25% over the year-ago period. Additionally, the company reduced its costs and expenses by 8% during the quarter, which allowed it to triple its adjusted earnings on a year-over-year basis to $5.33 per share. The numbers were better than consensus expectations of $4.96 per share in earnings on revenue of $39.2 billion.

It is worth noting that Meta's Q4 revenue grew at its fastest pace since the middle of 2021 and outpaced the company's full-year revenue increase of 16% to $135 billion. The tech giant's full-year earnings were up 73% to $14.87 per share on account of its focus on controlling costs and improving the efficiency of its business operations in 2023.

Investors should also note that Meta benefited from an improvement in digital ad spending last year. According to eMarketer, digital ad spending increased 10.7% in 2023 to $627 billion. So, Meta grew at a faster pace than the market in which it operates. Moreover, its 2023 revenue indicates that it controlled 21.5% of the digital ad space last year. That's an improvement over the 20.5% share in 2022 when Meta generated total revenue of $116.6 billion and digital ad spending stood at $567.5 billion.

Even better, Meta's revenue forecast for the first quarter of 2024 indicates that it could continue to corner a bigger share of the digital ad market. The company is anticipating almost $36 billion in revenue in the current quarter at the midpoint of its guidance range. That would be a 25% increase over the prior-year period's figure of $28.6 billion. Meanwhile, overall digital ad spending is estimated to jump 13.2% in 2024, which means Meta is on track to become a bigger player in this space.

Artificial intelligence (AI) could be a key reason why Meta seems to be gaining ground in the digital ad space. The company pointed out on its latest earnings conference call that it continues "to leverage AI across our ads systems and product suite" in a bid to improve monetization efficiency. Meta's offerings such as Advantage+, which allows advertisers to create automated ad campaigns with the help of AI and optimize those campaigns to drive greater returns on ad dollars spent, are gaining solid traction among its customers.

The company also released new generative AI features in the previous quarter for advertisers, with which they can generate multiple background images that complement product images and create alternative versions of advertising text so that they can choose the one that will help them improve reach. Meta management says that the "initial adoption of these features has been strong and tests are showing promising early performance gains."

The adoption of AI in the digital marketing space is forecasted to increase at an annual rate of almost 27% through 2030. More specifically, AI in digital marketing is expected to generate annual revenue of $79 billion in 2030 as compared to just $1.8 billion in 2022. So, Meta is pulling the right strings to ensure that it can keep winning a bigger share of the digital ad market by giving advertisers more AI-focused tools.

Stronger growth could lead to more upside

Given these points, it is not surprising to see why analysts are expecting Meta's growth to remain solid in the coming years.

As the chart above shows, Meta has received a nice bump in its revenue estimates for 2024, 2025, and 2026. What's more, analysts are expecting Meta's earnings to increase at a compound annual growth rate (CAGR) of 24% for the next five years. That would be a big jump over the 8.5% CAGR the company has clocked in the last five years.

Assuming Meta does clock 24% annual earnings growth over the next five years, its bottom line could increase to almost $44 per share in 2028 based on its 2023 earnings of $14.87 per share. Multiplying the projected 2028 earnings with the company's five-year average forward earnings multiple of 22 points toward a stock price of $968. That suggests a 106% gain from current levels.

Given that Meta is trading at 23 times forward earnings right now, investors are getting a good deal on the stock, which they may not want to miss considering the potential upside on offer.
