DNOW Inc.

The Company’s primary source of revenue is the sale of products forenergy and industrial applications based upon purchase orders or contracts with customers. Substantially all of the Company's revenue is recognized at a point in time once the Company has determined that the customer has obtained control over the product. Control is typically deemed to have been transferred to the customer when the product is shipped, delivered or picked up by the customer. The Company does not grant extended payment terms. Revenue is recognized net of any taxes collected from customers, which are subsequently remitted to proper government authorities. Shipping and handling costs for product shipments occur prior to the customer obtaining control of the goods and are recorded in cost of products.

The amount of revenue recognized reflects the consideration to which the Company expects to be entitled to receive in exchange for products sold. Revenue is recorded at the transaction price net of estimates of variable consideration, which may include product returns, trade discounts and allowances. The Company accrues for variable consideration using the expected value method. Estimates of variable consideration are included in revenue to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur.

See Note 9 “Business Segments” for disaggregation of revenue by reporting segments. The Company believes this disaggregation best depicts how the nature, amount, timing and uncertainty of revenue and cash flows are affected by economic factors.
