lease agreement financial
"entered into an amendment (the “Amendment”) to its lease agreement (the “Utah Avenue Lease”)"
Amendment financial
"entered into an amendment (the “Amendment”) to its lease agreement"
An amendment is a formal change or addition to an existing legal, regulatory, or corporate document, such as a contract, prospectus, regulatory filing, or company charter. It matters to investors because amendments can alter rights, deadlines, obligations, or risk profiles tied to an investment; think of it like editing a recipe—changing an ingredient or cooking time can significantly affect the final result.
Termination Agreement financial
"entered into a termination agreement (the “Termination Agreement”) with another landlord"
A termination agreement is a written contract that formally ends a prior agreement between two or more parties and sets the terms for how obligations, payments, and rights are resolved when that relationship stops. It matters to investors because it can change a company’s future cash flows, liabilities, legal exposure and access to assets or services—like the paperwork you sign when you break a lease that also settles who pays what and who keeps what.
Expansion Commencement Date financial
"effective as of May 14, 2026 (the “Expansion Commencement Date”)"
rentable square feet financial
"a total of approximately 3,531 rentable square feet of space"
Rentable square feet is the total floor area a landlord charges tenants for, including the tenant’s usable space plus a proportional share of common areas like lobbies, hallways and restrooms. Investors use it to calculate income and compare properties because rent and lease rates are typically quoted per rentable square foot; think of it as the full ticket price that includes your seat plus a share of the theater’s aisles and lobby.
