Key Terms

2 terms

undefinitized contract regulatory

"awarded a nearly $1.3 billion undefinitized contract for F135 engine spare parts"

A contract awarded before final price, scope, or delivery details are settled, where the buyer and seller agree to proceed while key terms remain to be negotiated. It matters to investors because revenue, profit margins, and cash flow tied to the work are uncertain until the contract is definitized, similar to starting a building project with only a rough plan — costs and timelines can change once the details are fixed.

indefinite delivery, indefinite quantity (idiq) regulatory

"The Indefinite Delivery, Indefinite Quantity (IDIQ) contract will fund fiscal year 2026"

Indefinite delivery, indefinite quantity (IDIQ) is a flexible contract method that allows a buyer to order an unspecified amount of goods or services over a period of time. It functions like a restaurant that agrees to provide meals whenever needed, up to a maximum amount, rather than committing to a fixed quantity upfront. For investors, IDIQ contracts offer ongoing opportunities and potential stability in revenue streams, though they also involve uncertainty about exact future orders.
