Operating cash flows
National Oilwell Varco’s (NOV) cash flow from operating activities (or CFO) turned negative in the first quarter to -$129 million despite 3% higher year-over-year revenues. Adverse changes in working capital led to the fall in CFO.
In the first quarter, its CFO decreased due to increases in accounts receivable and inventory and a decrease in accrued liabilities due to delayed orders and deferred deliveries. They were partially offset by increases in accounts payable and contract liabilities.
NOV’s free cash flow
National Oilwell Varco’s capex decreased 7% in the first quarter over the first quarter of 2017. Despite that, its capex exceeded its CFO. Its free cash flow (or FCF) was -$168 million in the first quarter compared to $69 million in Q1 2017. NOV’s FCF has been negative once in the past six quarters.
NOV’s oilfield services peer U.S. Silica Holdings’ (SLCA) FCF was $5.2 million in the first quarter. In Q1 2017, it was -$43.1 million. Year-over-year, its CFO increased in the first quarter, which more than offset the rise in capex and resulted in FCF improvement.
NOV makes up 3.1% of the SPDR S&P Oil & Gas Equipment & Services ETF (XES). XES provides exposure to the oil and gas equipment and services segment. XES has risen 5.5% in the past year compared to a 24.7% rise in NOV stock during the same period.
