The contract type sitting underneath a space company's revenue is not a technicality; it decides who absorbs the cost risk and, therefore, how much of the headline contract value is real money the company can count on. A few structures dominate the sector, and a public space company will usually disclose its mix because that mix shapes both its margins and its exposure. Intuitive Machines, which performs lunar and space-systems work largely for government customers, lays out the basic taxonomy in its annual report on Form 10-K filed with the U.S. Securities and Exchange Commission.

"We perform work under contracts that broadly consist of fixed-price, cost-reimbursable, time-and-materials or a combination of the three. Pricing for all customers is based on specific negotiations with each customer."— Intuitive Machines, Form 10-K, source

Each type allocates cost risk to a different party. Under a fixed-price contract, the company agrees to deliver for a set amount; if the work costs more than expected, the company eats the difference, and if it costs less, the company keeps the upside. Fixed-price work therefore carries the most cost risk for the contractor, which is why a company heavy in fixed-price, long-cycle space programs is exposed to cost-overrun and loss-contract charges if its estimates prove optimistic. The same Intuitive Machines filing notes that, historically, most of its revenue came from "fixed-price, long-term contracts for the delivery of payloads to the lunar surface," a concentration that places significant cost risk on the company.

A cost-reimbursable contract flips much of that risk to the customer: the company is reimbursed for its allowable, documented costs, usually plus a fee, so a cost overrun is largely borne by the buyer rather than the contractor. The tradeoff is a tighter, audited cost regime and typically thinner fee margins. A time-and-materials contract sits between the two, paying the company for labor hours at negotiated rates plus the cost of materials; it suits work whose full scope is hard to define up front. Most diversified contractors run a blend. Redwire, in its Form 10-K, states that its results "are substantially affected by our mix of fixed-price, cost-plus and time-and-material type contracts," a direct acknowledgment that the contract mix, not just the contract count, drives the financials.

Why an IDIQ ceiling is not an obligation

The structure most often misread in award headlines is the IDIQ, short for indefinite-delivery/indefinite-quantity. An IDIQ is not a single fixed order; it is a vehicle that sets a maximum dollar value, a ceiling, under which the customer can issue individual task orders over a period of years. Redwire's filing references "blanket purchase agreements and other indefinite delivery/indefinite quantity ('IDIQ') contracts" as part of its purchasing landscape. The defining feature of an IDIQ is that the ceiling is a cap on what could be ordered, not a commitment to order it. A company can hold a multi-billion-dollar IDIQ and receive only a fraction of that in actual funded task orders, because each order depends on the customer choosing to place it and funding it.

This is why the careful reading of a contract announcement asks what the structure is before it celebrates the number. A "$2 billion award" can mean very different things: a firm, funded, fixed-price order that maps almost entirely to backlog and future revenue; or an IDIQ ceiling that obligates almost nothing until task orders are issued. The difference between the ceiling and the obligation is the difference between committed business and a hunting license. The funded, obligated portion is what flows into backlog and, in time, into recognized revenue; the unfunded ceiling is potential that may or may not materialize.

How to read the mix

The contract type also interacts with how revenue is recognized, which is why the two disclosures are usually read together. A fixed-price contract for an integrated space build is often recognized over time using a cost-to-cost method, meaning the company's reported revenue and margin depend on its own estimate of total cost to complete, the very estimate that fixed-price terms put at risk. If costs on a fixed-price program run higher than estimated, the company not only earns a thinner margin but may have to revise previously recognized results and, in the worst case, record a loss on the contract as soon as the loss becomes probable. Cost-reimbursable work largely sidesteps that dynamic, since the customer bears the overrun, but it comes with audited cost regimes and lower fees. So the contract-mix disclosure and the revenue-recognition disclosure are two views of the same underlying risk: the mix tells you who bears cost overruns, and the recognition policy tells you how and when those overruns show up in reported results. Reading them in isolation misses how a fixed-price-heavy book and an estimate-dependent recognition method compound each other.

For an analyst, the contract type is a lens on both margin and risk. A fixed-price-heavy book offers margin upside if the company executes well but punishes estimate misses, especially on first-of-a-kind space programs. A cost-reimbursable-heavy book trades upside for protection, smoothing results at the cost of fee. An IDIQ-heavy pipeline looks large on paper but should be discounted to its funded, obligated portion before it is treated as revenue. The filings disclose enough to do this work: the contract-type mix, the share of revenue from fixed-price work, and, in the backlog disclosures, how much is firm and funded. Reading the structure first, and the headline number second, is the difference between knowing what a space company has actually won and merely knowing what it was eligible to win. The contract type is where that distinction lives.
