3 unique entity identifiers Total obligations: $4.75B FY2017–FY2026 high confidence

The total obligations figure opens to its derived USAspending citation. Confidence reflects entity resolution method (see methodology §4).

Family-level obligations: $4.75B— constant across all filing years listed below and non-additive (do not sum across rows; this figure is total family obligations over FY2017–FY2026, across the Department of Defense award corpus this site ingests — not all federal spending).

Public disclosures

Lobbying activity

Filings from the Senate Lobbying Disclosure Act database. Amounts are raw USD from LDA filings. Correlation is shown, not causation.

Wider than this screen — swipe the table sideways for the remaining columns.

Filing year	Filings	Income	Expense
2026	8	$205.0K	$0
2025	16	$435.0K	$0
2024	16	$410.0K	$0

Lobbying dollar aggregates carry derived LDA citations. Each figure opens to its formula and constituent filings. This table gives each filing year's filings, income and expense; lobbying and contracts reflect correlation, not causation. Income and expense are alternative disclosures on an LDA filing: a registrant reports one or the other. The two are not summed here. Read each column on its own.

Budget program mentions

Program elements with keyword co-occurrence in this company’s lobbying filings — a documented connection, not a statement that the filing names the program or that the company holds the program’s budget or work. For links backed by an actual award record, see Budget-Linked Awards below.

LDA Filing Mentions (81)

Lobbying filings with keyword co-occurrence against a tracked budget program — never a claim that the filing names the program. One row per filing × program, qualifying only when the exact PE/BLI code appears, a curated alias appears, or at least two distinct, non-generic title words appear together in the same filing (a single common word is never sufficient on its own — see the evidence tier badge on each row below). This is a documented co-occurrence, not evidence that the company works on the program.
