AMC Networks (AMCX -0.43%) surged 9% on Nov. 9, the day after announcing a solid Q3. Before you get on the bull and buy a few shares yourself, let's cut through the Wall Street noise, and see what numbers matter most to you in AMC Networks' Q3 earnings report.

What Wall Street cares about
Although earnings decreased slightly, AMC nonetheless surprised Wall Street.

Though analysts expected revenues to total $288.46 million, AMC beat their expectations, raking in $332 million.

Wall Street was so pleased with the company's 17% revenue gain since Q3 2011, that they forgave AMC's 7.5% decline in net income -- from $40 million to $37 million.

Of course, they also understood the root of AMC's earnings decrease. From July 1 to Oct. 21, Dish Network (DISH) dropped AMC's channels, depriving AMC of 13% of its audience. In addition, increases in marketing and programming expenses ate into AMC's profits.

Nonetheless, AMC's seemingly lackluster EPS still beat analyst estimates of $0.37. To top it off, AMC, and former parent company Cablevision Systems (NYSE: CVC), won a $700 million settlement from Dish.

How to invest in AMC foolishly
Although AMC owns several lines of business, the company earns the majority (around 90%) of its revenues from its "National Networks" division. Included in this segment are AMC, WE tv, IFC, and the Sundance channel. In turn, AMC earns its revenues through (1) its subscriber base, and (2) advertising fees.

Up until the Dish fiasco on July 1, a day after Q2 close, AMC had strengthened subscriber growth.

Now that Dish supports AMC networks, we should see subscriber growth rise significantly,  especially because audiences seem to crave Mad Men and The Walking Dead.

In the meantime, the popularity of AMC's programming has helped it increase its pricing power in licensing and advertising deals. (The company earns about 90% of its revenue from advertising and affiliation fees.)

We can see that revenues from affiliation fees -- like licensing of AMC's shows to Netflix (NFLX -3.98%) -- increased 24%, while advertising increased 9%.

The Foolish Bottom Line
At a P/E ratio of 24.3, AMC is pricier than other properties, like Discovery Communications (DISC.A), which trades at 20.6. With that in mind, it's also important to consider other factors, like AMC's massive $2.2 million debt. Some $1.5 million of that obligation is subject to variable interest rates. If these rates rise, AMC will be forced to spend more on debt and less on its operations. Nonetheless, AMC's subscriber, advertising, and affiliation fees will provide you with a general view of its top-line and bottom-line growth. So should you buy?

At the Fool, we don't believe in timing the market, so looking at one earning's report isn't enough. Foolish investors would do well to look at how well AMC has managed its businesses over the past several years.
