Using a 10b5-1 Plan for Scheduled Option Exercises

When and how to include option exercises in a 10b5-1 plan, the ISO-AMT timing implications, and cashless-vs-hold decisions inside the plan structure.

Most 10b5-1 discussion covers scheduled sales of vested shares. Less commonly discussed is using the plan for scheduled option exercises: the act of converting vested options into underlying shares, which is a separate event from selling those shares. Exercises can be included in a 10b5-1 plan, and doing so can provide the same affirmative-defense protection for the exercise and any associated sale. But the plan design has specifics for options that differ from straight stock sales: AMT timing for ISOs, cashless-vs-hold mechanics, and the interplay between exercise and post-exercise sale.

This article walks through how options fit into 10b5-1 plans, when they should be included, and the design choices.

What counts as an “exercise” for 10b5-1 purposes

An option exercise is the act of paying the strike price and receiving shares. For 10b5-1 plans:

Cashless exercise (same-day exercise-and-sell)

The plan both exercises the option and sells the resulting shares in a single linked transaction. The plan’s algorithm must specify both steps clearly.

Exercise-and-hold

The plan exercises the option but does not sell the shares. The executive pays cash for the strike, receives the shares, and holds.

Exercise-and-partial-sale

The plan exercises and sells a portion (often to fund the strike price or cover taxes), holding the rest.

All three are legitimate 10b5-1 structures. Each has different tax and cash-flow implications.

Why include exercises in the plan

Scheduled exercise at strike

If you want to exercise options periodically regardless of price, a 10b5-1 plan provides defensive timing. Example: exercise 5,000 options per quarter to manage AMT and build long-term-capital-gains holding period.

Exercise before expiration

Options near expiration need to be exercised or lost. A plan can schedule exercises to occur automatically before the expiration date, even if the executive is in a blackout or possesses MNPI at the time.

Cashless exercise tied to sale schedule

If the executive wants to monetize options periodically, cashless exercise under a plan captures both the exercise and sale in one algorithmic action. This is a common structure for exercise-and-sell-to-fund-lifestyle needs.

ISO AMT management

For ISOs, exercise triggers AMT (bargain element is included in AMT income). Structured exercises across tax years can manage AMT exposure. A plan enables this without requiring manual trades during windows.

Plan design for option exercises

Specify the trigger

Plan must specify: number of options to exercise, strike price, and date or condition of exercise.

Specify the disposition

  • Cashless: “Exercise and sell at market at the close of the trade date”
  • Exercise-and-hold: “Exercise only; do not sell”
  • Partial sale: “Exercise X; sell Y; hold remainder”

Specify the source of strike funds

For exercise-and-hold, the executive must fund the strike. Plan should specify whether funds come from a dedicated account, margin, or from a portion of the exercise proceeds (cashless carry).

Specify tax withholding

For NSOs, exercise generates ordinary income and tax withholding. The plan should direct how tax is withheld (sell additional shares, cash withholding from proceeds).

ISO-specific considerations

AMT timing

Exercising ISOs during a 10b5-1 plan still triggers AMT on the bargain element. Scheduling exercises under a plan does not change the AMT consequence; it just protects against insider-trading claims.

Qualifying-disposition path

If you exercise ISOs and hold for 1 year from exercise and 2 years from grant, the sale is a qualifying disposition. A 10b5-1 plan can cover the exercise (to build the holding period) and a subsequent sale (to execute the qualifying disposition). These can be in separate plans or a combination plan.

Disqualifying-disposition path

Cashless exercise of ISOs is always a disqualifying disposition (same-day exercise and sale does not meet the 1-year-from-exercise test). A plan executing cashless ISO exercise converts the bargain element to ordinary income.

$100K per year rule

IRC §422(d) limits ISOs exercisable in a year to $100,000 of FMV-at-grant. Above this, the excess converts to NSO. Plans exercising large ISO blocks may produce this conversion; design the plan to stagger exercises across years to stay under the limit.

NSO-specific considerations

Ordinary income at exercise

NSO exercise generates ordinary income equal to bargain element (FMV at exercise minus strike). This is taxable in the year of exercise and subject to employment taxes.

Cashless mechanics for NSOs

Cashless NSO exercise is common. The broker exercises, sells shares to cover strike and taxes, and delivers net proceeds to the executive.

Tax withholding

Companies must withhold on NSO exercises. Withholding rates vary by state. The plan should specify withholding mechanics.

Cooling-off and option exercises

Same cooling-off rules apply

Plans including option exercises are subject to the same 90-day (Section 16) or 30-day (non-officer) cooling-off rules as plans involving only share sales.

Exercise date and settlement

The exercise is the 10b5-1 event. A plan adopted in March cannot exercise in May; it must wait for cooling-off.

Sale triggered by exercise

If the plan pairs exercise with sale, both happen in the same transaction. The cooling-off applies to the pair.

Common plan structures for options

Structure 1: quarterly cashless exercise

Exercise 5,000 options per quarter at market. Sell resulting shares immediately. Use proceeds for diversification or cash needs.

Structure 2: annual exercise-and-hold

Exercise 20,000 options once per year, hold shares. Builds long-term-capital-gains holding period. Requires cash for strike and any NSO-related tax withholding.

Structure 3: expiration-driven exercise

Exercise all remaining options 90 days before expiration. Prevents expiration-related forfeiture if the executive is in a blackout near the deadline.

Structure 4: layered ISO/NSO

Exercise ISOs to track AMT thresholds. Exercise NSOs based on cash-flow and ordinary-income management. Plan has two layers, one for each grant type.

Cash-flow planning

Strike funding

Exercise-and-hold requires cash for the strike. For a 20,000-option exercise at a $5 strike, that’s $100,000 out of pocket. Plus any NSO tax withholding.

Tax-withholding funding

For NSOs, tax withholding at supplemental rates (22% federal or 37% above $1M) plus state rates can be significant. A $500,000 bargain element at 22% federal + 10% state = $160,000 of withholding.

Cashless proceeds

Cashless exercise nets the executive the post-tax proceeds. For a cashless NSO with $500,000 bargain and $160,000 withholding, the net is $340,000 before any platform fees.

Loan financing

Some brokers offer margin or loan facilities to fund exercises. This can work for strategic ISO exercises where holding the shares for long-term capital gains is the goal. Loans cost 6-10% annually plus setup fees.

Plan duration

Single-year plans

Simpler. All exercises and sales within 12 months. Good for executives with predictable near-term needs.

Multi-year plans

Cover multiple exercise events across 2-3 years. Useful for building holding periods for ISOs or staggering AMT across years.

Expiration-tied plans

End on a specific date tied to option expiration. Ensures all options are exercised before expiration regardless of the executive’s availability.

Common mistakes

Assuming exercise doesn’t need a plan

If you exercise options during a blackout or with MNPI, the exercise itself can be subject to insider-trading claims. A plan provides the affirmative defense.

Cashless ISO without understanding tax

Cashless ISO exercise is always a disqualifying disposition. Ordinary income on bargain. This can be intentional (avoiding AMT complexity) but should be deliberate.

Forgetting strike funding

Exercise-and-hold plans need cash. Many executives adopt plans without arranging the strike funding in advance, and exercises fail because cash is not available.

Mismatching exercise and holding period

Exercising in January with hope of long-term capital gains in June misses the 12-month rule. The holding period starts at exercise; you need 12 months past exercise for §1222 long-term treatment.

Not including tax withholding mechanics

NSO plans need explicit withholding instructions. Otherwise, the broker and the company’s payroll team disagree on who handles what, creating administrative issues.

Frequently asked

Can I combine option exercises and share sales in one plan?

Yes. A single plan can exercise options, sell exercised shares, and sell other vested shares. This is the most common structure for executive plans.

Does the sell-to-cover exception apply to option exercises?

The sell-to-cover exception in Rule 10b5-1(c)(1)(ii)(D) applies to share sales that cover tax withholding on equity-award vesting. It doesn’t strictly apply to option exercises, but a plan that pairs cashless exercise with an integrated withholding sale is generally treated as one plan (not two overlapping plans).

Does exercising options count as a 10b5-1 trade?

For purposes of the plan’s defense, yes. The exercise is an action under the plan protected by the 10b5-1 defense.

Can I exercise outside the plan while a plan is running?

If the plan specifies certain exercises, the specified ones are under the plan. Unrelated exercises outside the plan are not protected by the 10b5-1 defense. Outside-plan exercises during MNPI create exposure.

What about ISOs expiring during a blackout?

A 10b5-1 plan is the cleanest mechanism. The plan can exercise before expiration regardless of the current blackout status.

Does the broker handle ISO-specific tax reporting?

Brokers typically issue 1099-B on the sale. For ISOs, Form 3921 is issued by the company on exercise. Reporting coordination between broker and company is the company’s responsibility.

Can I use a plan for an early exercise of unvested options?

Yes, if the plan allows. Early exercise plus 83(b) starts the holding period at exercise. A 10b5-1 plan structured to exercise unvested ISOs with 83(b) is a sophisticated estate-and-tax-planning tool.

Next step

If you have options approaching expiration or want to manage ISO AMT timing, talk to your general counsel and broker about incorporating exercises into your 10b5-1 plan. Draft the plan with specific exercise schedules, cash-source instructions, and tax-withholding mechanics. Exercises inside a plan are protected; exercises outside a plan during MNPI are exposed. Coordinating the two is one of the higher-leverage uses of the 10b5-1 framework.
