Insights M&A Wealth Planning Guide

Why this Guide Exists

The most consequential financial decisions of an executive's career happen in the 12 months around a liquidity event. An acquisition, an IPO, a change-of-control transaction — these moments compress more high-stakes wealth decisions into a year than the prior decade combined.

The problem isn't that executives don't know this. It's that the planning architecture around them is built for the long, calm middle of the career — generalist advisors with retirement-focused playbooks, CPAs who file returns but don't proactively model multi-year scenarios, attorneys who handle the legal documents but stay in their lane. By the time the right person is in the room, the most valuable planning windows are often closed.

This guide is the framework Lake House Private Wealth Management uses when working with executives through liquidity events. It's not a substitute for legal or tax advice. It's the map of what to think about, in what order, before each window closes.

If you're reading this 12 months before a known close date, you have leverage. If you're reading it 90 days before, you have less. If you're reading it the week after, you have almost none. That asymmetry is the entire point of this guide.

What counts as a liquidity event
For the purposes of this guide, a liquidity event is any transaction or event that converts illiquid executive equity into liquid wealth, or fundamentally changes the structure of an executive's compensation. The most common forms:

- Cash acquisition: A public or private company is bought for cash. Timeline: Announcement to close, 60–180 days.

- Stock-for-stock merger: One public company absorbs another in an equity-only deal. Timeline: 90–270 days.

- Cash-and-stock deal: A mix of cash consideration and rollover equity. Timeline: 90–270 days.

- IPO: Private company goes public via traditional IPO. Timeline: 6–12 months from S-1 filing.

- Direct listing / SPAC: Alternative paths to public market. Timeline: Variable; often faster than IPO.

- Tender offer: Hostile or friendly cash bid for shares. Timeline: 30–60 days.

- Change-of-control: Sale of a controlling interest without full acquisition. Timeline: Variable.

- Going-private transaction: Public company taken private by PE or strategic buyer. Timeline: 90–180 days.

- Recapitalization: Major capital structure change creating partial liquidity. Timeline: Variable.

Each has different tax treatment, different planning windows, and different consequences for executive equity. The 12-month framework in this guide applies across all of them, but the specific tools available vary.

The 12-month framework
Lake House organizes liquidity event planning into three phases:

- Pre-close (90–180 days before) — the window when most powerful planning tools are still available
- At close — execution decisions made during the transaction itself
- Post-close (12–36 months after) — the work of integrating the newly liquid wealth

Each phase has its own decision architecture. Skipping any of the three is where wealth gets left on the table.

Phase 1: Pre-Close Planning (90–180 Days Before)
This is the highest-leverage phase. Decisions made here have multi-million-dollar tax consequences and largely close once the deal is announced or signed.

280G change-of-control payment analysis
Section 280G of the Internal Revenue Code imposes a 20% excise tax on "parachute payments" — change-of-control payments to executives that exceed three times the executive's base amount (five-year average compensation). The tax falls on the executive personally, and the company loses its tax deduction on the excess parachute portion.

For executives at the disqualified-individual threshold — typically the top 1% of executives by compensation or any executive whose stock awards accelerate at change-of-control — 280G can produce six- or seven-figure unnecessary tax bills if not modeled and structured properly.

Key planning tools that require pre-close attention:

- Cleansing votes for private company executives (requires shareholder approval to exempt parachute payments — must occur before the change-of-control event)
- Restructuring acceleration provisions in employment agreements to avoid triggering parachute thresholds
- Allocating parachute payments to non-compete consideration which can be excluded from 280G calculations
- Modeling base amount lookback calculations to identify how close the executive is to the 3x threshold

The window for many of these tools closes the moment a definitive agreement is signed.

Equity acceleration and modification
Most executive equity grants — RSUs, options, performance shares — include change-of-control acceleration provisions. The specific language in those provisions determines whether vesting is automatic, double-trigger (requires both the change-of-control and a termination), or discretionary.

The planning work here involves:

- Reading the actual grant agreements (not the summary plan description — the underlying agreements)
- Modeling whether to accelerate vesting in the executive's favor or defer it for tax management
- Coordinating with HR on the timing of vesting events to optimize across tax years
- Reviewing 83(b) election eligibility for any rollover equity that will be issued at close

For executives with significant unvested grants, this single area can shift the eventual after-tax outcome by 15–25%.

Concentrated stock and option exercise sequencing
Most pre-acquisition executives hold a significant concentrated position in employer stock — vested but unsold shares, exercised but unsold options, ESPP holdings, and direct purchases over years of employment. The total concentration often exceeds 50% of the executive's net worth.

Pre-close planning typically includes:

- 10b5-1 trading plan establishment: if not already in place, before material non-public information about the transaction is known to the executive (timing is critical; this window often closes 60–90 days before announcement)
- Pre-deal diversification: through plan-sanctioned sales that occur before deal-specific MNPI restrictions take effect
- Option exercise strategy: early exercises to start QSBS holding periods, AMT preference modeling, or pre-deal exercise to lock in current valuations
- Charitable gifting of appreciated shares: using donor-advised funds (DAFs) or charitable lead trusts to remove appreciated stock from the estate at peak valuation

Estate freezing and family transfer
Liquidity events typically cause a meaningful step-up in the executive's net worth. From an estate planning standpoint, the most powerful family transfer techniques work before that valuation jump occurs, not after.

The toolkit:

- Grantor retained annuity trusts (GRATs) funded with pre-IPO or pre-merger equity that has known appreciation pending
- Spousal lifetime access trusts (SLATs) using lifetime gift exemption
- Defective grantor trusts (IDGTs) with installment-sale-to-trust structures
- Family limited partnerships for executives with significant additional holdings
- Direct lifetime gifts of pre-event-value shares using exemption before the upcoming sunset of the 2017 Tax Cuts and Jobs Act doubling

Each requires substantive lead time. Most require 30–90 days minimum to establish, fund, and document.

Charitable gifting strategy
Pre-close is the optimal time to lock in charitable deductions at the highest possible valuation. Tools include:

- Donor-advised fund (DAF) contributions of appreciated shares, deductible at current FMV
- Charitable remainder trusts (CRTs) for executives wanting income from contributed shares
- Charitable lead trusts (CLTs) for family-wealth-transfer-oriented giving
- Private foundations for executives with sustained large-scale giving plans

The mechanics are straightforward; the timing is critical. Contributions made before deal announcement are valued at pre-deal share price. Contributions made after are valued at the announcement-bumped price — typically much higher tax cost.

Coordination with M&A counsel and tax advisors
The most common mistake at the pre-close stage isn't missing a planning tool — it's failing to coordinate across professionals. The executive's M&A attorney is focused on deal terms. The CPA is focused on annual filings. The wealth advisor (if engaged) is focused on portfolio management.

The coordination work involves:

- Joint scenario modeling across attorney, CPA, and wealth advisor
- Aligned timing for elections, exercises, and gifts
- Single source of truth for the executive's overall position and cash flow needs
- Document review by all three professionals before signing

Lake House operates as the coordinating quarterback in this phase — running the project plan, surfacing decisions on a calendar, and ensuring the right professional is in the room for each conversation.

Phase 2: At Close
Decisions made at the close itself are largely the consequence of pre-close planning, but a few discrete elections happen at the moment of the transaction.

Cash-out vs. rollover equity
For deals offering rollover equity in the acquiring company, the executive often has a choice: take cash consideration, take rollover equity, or split. The decision drives meaningfully different tax outcomes:

- All cash: immediate tax recognition on capital gain (or ordinary income for certain equity types), full liquidity
- All rollover: deferred taxation, continued concentration risk, lockup periods
- Split: balance of liquidity and tax deferral

The decision depends on the executive's diversification needs, the strength of the acquiring company's outlook, and the executive's role going forward.

Section 1202 QSBS qualification
For executives at acquiring companies that originated as Qualified Small Business Stock (QSBS) issuers — common in tech and biotech — there's a federal income tax exclusion of up to $10 million (or 10× basis) on gain from QSBS sales held over five years.

Key planning considerations at close:

- Confirming QSBS qualification of the original stock issuance (the company must have met QSBS requirements at issuance)
- Determining whether rollover equity in a stock-for-stock deal preserves QSBS status (often it does, but rules are technical)
- Coordinating with tax counsel on Section 1045 rollovers if the executive plans to reinvest proceeds in another QSBS-eligible company within 60 days

For founder-executives and early employees of acquired QSBS companies, this single provision can shield millions of dollars from federal tax.

Section 83(b) elections on rollover equity
When deals include grant of new restricted equity in the acquiring company at close — common in private-to-private and private-to-public transactions — executives have a 30-day window to file an 83(b) election. The decision involves modeling:

- Tax rate today vs. expected tax rate at vesting
- Likelihood of forfeiture if the executive leaves before full vesting
- Cash flow to pay current tax on the election

Late 83(b) elections are not curable. The 30-day window is hard.

Installment sale and earnouts
For private company transactions structured with earnout consideration — additional payments contingent on post-close performance — the tax treatment depends on whether the earnout qualifies for installment sale treatment under Section 453.

The basic mechanics:

- Earnouts qualify for installment treatment unless the executive elects out
- Each year's payment is treated as part principal (basis recovery) and part gain
- Imputed interest may apply
- Multi-state apportionment can affect overall tax burden

For executives with earnouts of $1M+, the decision to elect out of installment treatment vs. accept it can shift the effective tax rate by several percentage points.

Phase 3: Post-Close Integration (12–36 Months After)
The work doesn't end at close. The first 12–36 months after a liquidity event are when newly liquid wealth gets either coordinated or eroded.

Diversification strategy
Most pre-close executives hold 50–70% of net worth in a single position. Post-close, the goal is typically to diversify aggressively while managing tax cost.

The framework:

- Tax-aware sell-down plan: sequencing sales across tax years to minimize bracket creep
- Direct indexing for tax-loss harvesting: using a custom-built equity portfolio with hundreds of individual positions to generate offsetting losses against the concentrated sale gains
- Charitable rebalancing: donating appreciated shares to charity while replacing with cash purchases of diversified positions
- Exchange funds: for executives unable or unwilling to sell, pooled diversification vehicles
- Tax-loss harvesting at the household level: across taxable accounts, multiple positions, multiple years

Lake House typically targets full diversification within 24–36 months of close, depending on the executive's situation and the size of the position.

Concentrated successor-company stock unwinding
For deals involving rollover equity, the post-close work includes managing the new concentrated position in the acquiring company. Considerations:

- Lockup expiration: when the executive is freed from contractual sale restrictions
- 10b5-1 plan: re-establishment for executives continuing in roles with MNPI access
- Section 1202 holding period management: if rollover preserved QSBS, calendar to the 5-year threshold
- Insider trading window compliance: for executives in officer or director roles

Multi-year tax planning
The years immediately after a liquidity event present unusual tax-planning leverage:

- Roth conversion opportunities in lower-income years between the executive's high earning years
- Tax-loss harvesting at scale, often offsetting gains for 5–10 years
- Bracket management — sequencing capital gains realizations across tax years to stay below high-bracket thresholds
- State residency considerations — for executives with flexibility on where they live, the post-close period is often the right time to evaluate state tax exposure

Family wealth transfer
Post-close is when many executives first contemplate generational wealth transfer at scale. The decisions here include:

- Funding GRATs, SLATs, and other lifetime gift vehicles
- Establishing 529 plans for children and grandchildren
- Updating estate documents to reflect new asset levels
- Considering generation-skipping trusts for executives wanting multi-generational structures
- Reviewing beneficiary designations on all accounts

Where this work usually goes wrong
Most executives engage a wealth advisor only after the deal closes. By then, the highest-leverage planning windows — pre-close 280G structuring, QSBS qualification, GRAT funding, charitable contribution timing — are already closed. The remaining work is real but represents perhaps 40% of the total value that could have been preserved.

The pattern: an executive learns of an acquisition. They focus on the deal terms, their employment agreement, their compensation in the new entity. The wealth-side decisions feel like something to handle "after things settle." By the time they're ready for that conversation, the planning windows have largely closed.

Lake House works alongside corporate counsel and the CPA from the 90-day mark — earlier when possible — so the moment compounds wealth rather than evaporating it.

What Lake House does in this work
Three things specifically:

Coordination. Lake House serves as the quarterback across the executive's existing professional team — M&A counsel, deal CPA, estate attorney, HR. We don't replace these professionals. We coordinate them. The project plan, the calendar of decisions, the modeling of trade-offs, the documentation — Lake House runs it.

Specialized planning. Within our scope as an SEC-registered investment adviser, Lake House provides investment management, tax-aware portfolio construction, and integrated financial planning. The specific tax election work and legal structuring work is performed by the executive's CPA and attorney, with Lake House providing the financial modeling and integration.

Multi-year execution. The work doesn't end at close. Lake House typically engages with executive families across the full 36-month post-close integration window, not as a one-time consultation.

Who this guide is for
This guide is written for executives in the senior leadership of public or private companies who are either:

- Currently in or approaching a liquidity event (announced or under negotiation)
- 6–18 months out from an anticipated event based on company trajectory
- Past a liquidity event but within the 36-month post-close integration window

The principles also apply to early employees of acquired companies with meaningful equity, founders, and family members of executives navigating these events.

Next steps
If you're navigating an actual or anticipated liquidity event, the most valuable next step is usually a conversation that maps where you are in the timeline against the planning windows that remain.

Lake House offers a confidential, 30-minute Discovery Call to do exactly this. No pitch. No obligation. Just a clear read on which windows are still open and what the highest-leverage moves look like from where you sit.
