stock award agreement financial

"pursuant to the terms of a stock award agreement under the Chart Industries"

exempt transaction financial

"These securities were granted on April 1, 2026, in an exempt transaction, pursuant"

A transaction in which securities are sold without the issuer having to register them with the securities regulator because the sale meets legal exemptions (for example private placements, certain small offerings, or sales to accredited investors). It matters to investors because exempt transactions often involve less public disclosure and more limits on resale, like buying something from a private marketplace rather than a public store—so information access and liquidity can differ from registered offerings.
