Source: SBIR.gov award data (award_data.csv downloaded 2026-10-28; awards through 2023). overall/byCohort: share of Phase I awards followed by a Phase II to the same firm from the same agency/component with Phase II award year ≤ Y+3; each Phase II counts for at most one Phase I, matched first on identical topic code, then (for agencies whose topic code is a per-round solicitation number) to any remaining same-firm Phase II that is not Direct-to-Phase-II (firm matched on DUNS, else normalized name + state; matchedByTopicShare = share of matches made on topic code). firmLevel: share of distinct firm × Phase I-year pairs that received any Phase II from the same agency/component within 3 years (looser; inflated by multi-award firms). overall figures use cohorts 2015–2020, the cohorts whose 3-year window has closed in this data vintage; later cohorts are partial. p2WithoutMatchedP1Share5y: share of 2021+ Phase II awards with no matched Phase I (largely Direct-to-Phase-II).
