• Contracts worth the minimum value or more (the larger of their current value and their value with all options) whose current end date falls in the window, as of each contract's latest action in the data (FY2023 on). Agencies extend, re-award or end contracts early, so an end date is a signal, not a schedule.
• Follow-on notice = a SAM.gov notice from the same contracting office with the same NAICS or PSC, posted from 18 months before the contract ends: a likely match for you to confirm, not a link the government publishes.
• Others winning this work = the largest other companies by contract obligations from the same bureau (e.g. the Army, not all of DoD) in the same NAICS code over the last two fiscal years.

Data as of 2026-09-30. Timelines: now to the current end · with every option · follow-on notice responses due.
