Commenting on the results, CEO Josh Sapan said in a press release:

AMC Networks is off to a strong start in 2015, with returns on our content investments generating significant growth in our revenues, AOCF [adjusted operating cash flow] and operating income. Viewers continue to embrace our original programming, including AMC's The Walking Dead and our new original series Better Call Saul, which was the most-watched new series on cable in key advertiser demos, this broadcast season. Our international business is developing well, with our portfolio of global channels and strong local brands benefiting from growing demand from distributors. AMC Networks continues to operate from a position of strength, with high quality programming, clearly defined brands and strong audience support that drives financial performance and our ability to create value for shareholders.

What went right: Distribution revenue (up 25.6%) grew faster than ad revenue (25.3%) in the key National Networks segment that produces and licenses programming for distribution across AMC's various networks: AMC, IFC, WeTV, Sundance TV, and AMC International. Higher affiliate fees from cable and satellite operators helped contribute to growth in distribution revenue. A recent multi-year exclusive tie-up with Hulu could add even more in future quarters while giving AMC the ammo needed to demand premiums from new partners. In the meantime, AMC is doing well turning top-line growth into cash to fund new productions and for debt service. Adjusted cash from operations (AOCF) ballooned 55.1% year-over-year to $259.2 million.

What went wrong: AMC is still figuring out how to turn acquired International operations into a meaningful catalyst for the business. Revenue from the segment surged 38.9% year-over-year and AOCF more than doubled over the same period, but at $5.7 million AMC gets just 2.2% of its cash flow from overseas operations. This summer's Fear The Walking Dead spinoff series could change the equation when it becomes the first major in-house produced series to also be distributed by AMC International.

What's next: AMC Networks declined to include second-quarter guidance in its press release. Analysts tracked by S&P Capital IQ have the company generating $609.58 million in revenue and $1.06 a share in adjusted profit, versus $522.09 million and $0.86 a share in last year's Q2. Longer term, analysts have AMC Networks growing earnings by an average of 13.05% annually during the next three to five years.

And in terms of the overall business? Investors should keep a close eye on international operations. Third-quarter results could include meaningful contributions from Fear The Walking Dead in broadcast territories that already welcome the parent series. Right now, that includes parts of Africa, Asia, Australia, Europe, and Latin America.
