A Restricted Stock Unit (RSU) is an equity-compensation instrument representing a contractual promise to deliver shares (or cash equivalent) upon satisfaction of vesting conditions — typically time-based, performance-based, or hybrid. RSUs differ from stock options in that recipients do not need to pay an exercise price to receive shares; vesting itself transfers value, with the company’s tax-withholding obligations and recipient’s ordinary-income recognition both triggered by vesting events. RSUs have become the dominant equity-compensation tool at late-stage and public companies, replacing stock options for most rank-and-file employees in mature companies.

RSU tax treatment: (i) no tax at grant — RSUs are a promise of future shares, not current property; (ii) ordinary income at vesting equal to the fair-market value of shares delivered at vesting — taxed at recipient’s ordinary income rate; (iii) payroll-tax withholding at vesting — typically handled via “sell-to-cover” arrangements where the company sells a portion of vesting shares to satisfy tax-withholding obligations, delivering net shares to employee; (iv) capital-gains treatment on subsequent share sale — long-term if held >1 year from vesting; short-term if sold sooner; and (v) basis equal to FMV at vesting — establishes the floor for subsequent gain/loss calculation.

RSUs advantages compared to stock options include: (i) value certainty — vesting always delivers value (assuming positive share value), unlike options that can be “underwater” with strike above FMV; (ii) simpler administration — no exercise process, no AMT concerns, no §409A valuation requirements; (iii) more predictable dilution — RSU share count converts 1:1 to outstanding shares at vesting, easier cap-table modeling than options; (iv) aligned with public-company practices — pre-IPO companies adopting RSUs ease the public-company transition; and (v) international-employee friendliness — RSUs often work better than ISOs/NSOs for non-U.S. employees in jurisdictions with complex option-tax treatment.

RSU disadvantages: (i) no capital-gains advantage on appreciation between grant and vesting — unlike early-exercised options with 83(b) elections; (ii) tax recognition at vesting regardless of share liquidity — employees at pre-IPO companies receive RSU vesting tax liability without ability to sell shares to fund the tax, creating cash-flow stress; and (iii) “double-trigger” structures necessary for pre-IPO companies — RSUs at pre-IPO companies typically vest only upon BOTH time-based service AND liquidity event (IPO or acquisition), avoiding the cash-flow problem but creating retention risk if liquidity is delayed.

For Turkish-founded Delaware-incorporated companies preparing for late-stage growth or IPO, RSU program design becomes increasingly relevant: transitioning from option-based compensation to RSUs for new hires, managing the conversion of pre-existing options to RSUs for retention purposes, designing double-trigger structures for pre-IPO RSU vesting, coordinating RSU administration with public-company-readiness infrastructure, and integrating RSU programs with U.S./international payroll-tax frameworks. Vircon Legal advises Turkish founders on RSU program design — eligibility framework, vesting-mechanics tailoring, double-trigger structuring, plan-document drafting, administration-platform integration (Carta, Shareworks), and the strategic transition from option-centric to RSU-centric equity compensation as companies mature toward exit.
