Employee Stock Option financial

"security_title: "Employee Stock Option (Right to Buy)""

An employee stock option is a promise that lets a worker buy company shares later at a predetermined price, often after they stay for a certain period or meet performance goals — think of it like a coupon that locks in today's price for a future purchase. It matters to investors because options align employees’ incentives with company performance, can increase the number of shares outstanding (dilution) when exercised, and represent a compensation cost that affects reported profits and shareholder value.

Exercise price financial

"conversion_or_exercise_price: "0.5850" per share"

The exercise price is the fixed amount at which you can buy or sell an asset, like a stock, when using an options contract. It matters because it helps determine whether exercising the option will be profitable or not, depending on the current market price. Think of it as the set price you agree on today to buy or sell later.

2023 Equity Incentive Plan financial

"authorized for issuance under the Company's 2023 Equity Incentive Plan"

evergreen provision financial

"pursuant to an annual "evergreen" provision"

An evergreen provision is a clause in a financing or contract that automatically renews or replenishes the arrangement unless one party actively cancels it, like a subscription that keeps renewing each term. For investors it matters because it creates predictable, ongoing access to funding or ongoing contractual obligations — helping liquidity and planning — but can also hide long-term commitments or dilution risks if not reviewed.

Form S-8 regulatory

"until the filing of the Company's registration statement on Form S-8"

A Form S-8 is a U.S. Securities and Exchange Commission registration that lets a public company set aside shares for employee benefit plans and stock-based compensation. Think of it as opening a dedicated account that authorizes the company to issue or reserve stock for workers and directors; it matters to investors because it enables share dilution when those awards are granted or exercised and signals how management is compensated and incentivized.

What are the key terms of the CalciMedica (CALC) stock option grant?

The grant covers 65,124 options with an exercise price of $0.585 per share and an expiration date of April 4, 2036. These options allow the holder to purchase CalciMedica common stock at that fixed price before expiration, subject to vesting.

How do the CalciMedica (CALC) options granted to the CSO vest?

Vesting begins on April 1, 2026, when 1/48 of the options start vesting in equal monthly installments over four years. This means the award becomes exercisable gradually, encouraging longer-term alignment between the executive and shareholders.

Did the CalciMedica (CALC) Form 4 show any stock sales or purchases in the market?
