Establishes the "Missouri Defense and Energy Independence Act"

HB 1659 creates a Missouri grant program to help businesses convert facilities to produce critical defense and energy materials (like strategic chemicals or minerals). It directly affects Missouri-based companies that make at least $500,000 in private investments to convert facilities, offering grants up to $1 million per company for qualified conversion costs. The bill establishes a dedicated $10 million annual fund (subject to appropriation) and requires companies to complete conversions within 24 months or repay grants. Companies must submit detailed plans, prove compliance with labor/environmental laws, and the state will report annually on applications, grants, and economic impact.
