Time Warner Cable Inc. (NYSE:TWC)

The financial performance from 2011 to 2015 is characterized by a significant structural shift in cost management and a subsequent gradual compression of operating and net margins. A primary driver of the early period's profitability was a sharp reduction in content-related expenses, although later years show increasing pressure from operating costs and a decline in overall operating efficiency.

Gross Margin and Cost of Revenue

A substantial increase in gross profit margin is observed between 2011 and 2012, rising from 53.56% to 78.01%. This shift was directly attributable to a significant decrease in programming and content costs, which fell from 46.44% of revenue in 2011 to 21.99% in 2012. Following this peak, gross margins experienced a gradual downward trend, declining to 75.46% by 2015, indicating a steady increase in the cost of providing content relative to revenue.

Operating Expense Trends

Operating expenses exhibit diverging patterns. Sales and marketing costs showed a consistent year-over-year increase, rising from 8.49% in 2012 to 10.04% in 2015. Customer care costs also trended upward from 3.46% to 3.80% over the same period. Conversely, other operating expenses decreased from 22.76% in 2012 to 20.24% in 2015. Depreciation remained relatively stable, fluctuating within a narrow band between 14.19% and 15.22% of revenue.

Operating Income Stability and Decline

Operating income remained remarkably stable between 2011 and 2014, hovering around 20.3% to 20.8% of revenue. However, a noticeable contraction occurred in 2015, where operating income dropped to 17.89%. This decline suggests that the growth in sales, marketing, and content costs began to outweigh the efficiencies gained in other operating areas.

Financial Costs and Non-Operating Items

There is a clear downward trend in net interest expense, which improved from 7.72% of revenue in 2011 to 5.91% in 2015. This indicates a reduction in the relative burden of debt service. Non-operating income remained volatile, with a notable peak in 2012 due to a gain on the sale of an investment in Clearwire and a modest contribution in 2015 from a settlement regarding a wireless agency agreement.

Net Profitability

Net income attributable to shareholders peaked in 2012 at 10.08% of revenue. Despite the improvement in interest expenses, the overall net margin declined to 7.78% by 2015. This erosion of the bottom line aligns with the contraction in operating income and the incremental rise in sales and content expenses.
