Along with my three cash flow markers, we should probably include change in working capital. This is a standard accounting construct that is reported in the cash flow statement, and it is quite informative. Working capital is the net of current assets (mostly cash) and current liabilities (mostly debt payments due within 12 months). So it is close to net cash flow (change in cash position), but it also is sensitive to mounting pressure from current liabilities too. So it is a little more conservative to watch than just net cash flow. So in my marker scheme positive change in working capital would stand between net cash flow and what I have dubbed DevCo Cash Flow. And Free Cash Flow is now the fourth marker. Of these four, all but DevCo CF are standard accounting constructs.
So I would encourage investors to look at the table at the head of the Q4 2015 Review. You will see Change in Working Capital is a middle row. Last quarter is was a decline of $38.1 M. But notice that is has not always been negative. It was positive for the first 3 quarters of 2014, but has been negative for the last 5 quarters. I suspect this is a large measure of what has emboldened shorts to attack the stock. Regardless of a company's longterm prospects which may be quite compelling, shorts know that as working capital declines the company is headed for crisis, which is sufficient to drive down share price.
So let's size this up in the last 5 quarters working capital has declined $221.9M while the company installed 1047 MW. So WC fell by $0.21/W installed. In this period, the company spent $607.5M on sales and marketing, or $0.58/W, in an effort to continue doubling another year. From 2014 the eyes of Wall Street was on whether SolarCity could continue to grow at this incredible rate, and management attempted to prove that it could. Unfortunately it came at the cost of eroding working capital and throwing the stock valuation into crisis.
What is the road forward? SolarCity has done a tremendous job at reducing the installation cost per Watt. This is truly foundational. What they have lacked is discipline around growth appetite and marketing efficiency. Spending $0.58/W on sales is simply too high. Management acknowledges this and has shown in Q4 that they are cutting this cost. Marketing spend is obviously crucial to how fast they can grow. Waiting for lenders to pull the plug, as Benson has warned, is not the constraint that management should risk. It is not what should prevent SolarCity from installing 1250 MW this year. Rather, in my view it is marketing efficiency that should properly constrain growth. Management should only grow sales to the extent that they can end the year with more working capital. If that is less than 1.25 GW, so be it. But that need not be the case, if they improve marketing efficiency.
So where do they stand? 2015 Q4 the decline was $38.1 M on installation of 272 MW. This is $0.14/W that they must cut from total cost per Watt, but I believe most of it should come from sales. So sales and marketing was $0.56/W. I think they need to reduce this to $0.42/W. I believe this is possible. I also believe that the low 180 MW guidance gives them latitude to move in that direction.
In terms of price action, I think that once SolarCity starts to build working capital, putting an end to this 5 quarter run of declines, shorts will back off a bit and some investors will return. So I am looking to see some improvement in WC and sales $/W in Q1. It think progress here will stabilize the stock, and more progress in Q2 will boost the stock price. Right now, I think the rationale for buying the stock is that you believe that management will turn this corner such that the stock price will be increasing after Q1 ER. If you don't have that confidence in management, you should not be in this stock and should wait until WC starts improving.
As long as WC declines, the stock price will decline as well. This has little to do with the longterm prospects for solar or SolarCity in particular. I remain quite bullish for both. This is about whether management can manage cashflow and not crash the company in pursuit of shortterm growth target. This is not even a question of business model, although that is evolving anyway, but it is a question of managing cash flow. I believe our new CFOs at both SolarCity and Tesla get this.
