The streaming firm posted $4.5 billion in operating income in its most recent quarter, up 37%. With revenue up 12%, the company hit its own forecast. Shares fell in extended trading once the outlook was out.

A HyperWeb analyst who went over the shareholder letter sees it as a timing issue rather than a slump. Expense moves propped up this quarter but will drag on the next, not to mention a staffing charge.

The Numbers Behind the Beat

Management set a margin target of 33.2%. They came in at 34.6%, beating it by 1.4 points. On some $12.9 billion in revenue, that is worth in the region of $180 million. The company puts it down to expense timing and a bit of upside on revenue.

But such gains are fleeting; costs can be pushed into a later quarter. Earnings per share rose 49% to $0.87 for the same reasons. The letter does not break out where the revenue growth is coming from, be it memberships, advertising, or pricing.

Operating income rose 37% while revenue rose only 12%, meaning costs have not kept pace with sales.

A Muted Year-Ago Figure

Last year’s quarter also included a one-off Brazilian tax bill of $619 million. Operating income was $3.25 billion on $11.51 billion in revenue for a 28.2% margin. Add back the charge, and the margin is closer to 33.6%. 

Viewed in that light, the gain is one point, not six. It is a real improvement, but the reported numbers make it look bigger. Earnings are distorted in the same way. The 49% rise in per-share profit is off a low base of $0.58. Investors would do well to take the headline rate with a grain of salt.

The Outlook

For the final quarter, management has guided sales to roughly $13.4 billion, a 12% increase. With a 26.0% margin target (the year-ago figure was 24.5%), that translates to operating income in the vicinity of $3.48 billion. 

The comparable quarter a year back was about $2.93 billion, so there is 19% growth there. These are rounded estimates, though. What matters more is the gap to the quarter just filed. 

By that measure, profit is down about 23%, or $1.0 billion, even as revenue rises. Margin is driving the decline. Revenue guidance is in line with this quarter, so the sales side is steady. The step down in margin is the talking point.

The Staffing Charge

Some 120 basis points of the 26.0% target come from recent headcount reductions. A basis point is a hundredth of a percentage point, or $160 million on guided sales. 

Absent the charge, the margin would be 27.2% and operating income $3.64 billion. The charge is a piece of the $180 million timing beat. One-time costs and timing gains cancel each other out between the two quarters. 

The savings from the staff cuts will come in gradually, while the charge comes in all at once. That is why the guide has dipped. Restructuring usually lowers costs, and how that plays out will inform the next round of estimates.

If the 34.6% margin repeated on $13.4 billion in sales, operating income would be $4.64 billion. The distance to the 26.0% guide is $1.15 billion, and the staffing charge only accounts for $160 million of that. The rest reflects lower-margin assumptions in the forecast. A 1.4-point beat like this quarter would put the final quarter at around 27.4% or $3.67 billion.

Content and Retention

Amortization of programming costs is set to run 10% higher for the year. The first half has already seen faster growth, and those swings can affect margins on their own. Programming spend is as worthy of note as headcount. A big release slate means costs before revenue, and timing will determine margin.

Then there is retention. Management notes membership has been healthy across the board. Churn has been better than last year in the U.S. and globally and has topped the forecast. 

With less churn, the 12% revenue number is easier to hit without promotion. Keeping a member saves the marketing cost of getting a new one. As the company has stopped reporting subscriber counts quarterly, any word on churn is worth paying attention to.

For those holding the stock, three things stand out: the final quarter margin versus the 26.0% target, the pace of content amortization, and the savings from the cuts. Revenue growth of 12% is the given. 

Add what management says on release timing, and the quarter-to-quarter movement is largely explained. How much the shares move on the guidance should dictate position size. Staged entries mitigate risk, and a diversified portfolio can offset streaming with more stable sectors.
