409A Valuation After a Down Round: Your Obligations

A down round is one of the most consequential events in a startup's life — financially, operationally, and legally. When new preferred shares price below the prior round's per-share price, the immediate conversation turns to dilution, anti-dilution adjustments, and investor relations. But there is a parallel compliance obligation that founders and CFOs cannot afford to overlook: the 409A valuation down round requirement.

Under IRC Section 409A, every stock option granted to employees must have an exercise price at or above the fair market value (FMV) of common stock on the grant date. A down round fundamentally changes what that FMV is. The moment the round closes, any prior 409A valuation is effectively invalidated as a basis for new grants. Issuing options against a stale pre-down-round 409A is not just a paperwork error — it is a structural compliance failure that can expose your entire team to immediate income recognition, a 20% federal excise tax, and IRS interest charges.

This guide covers exactly what your obligations are in a 409A after down round scenario: why the round triggers a new valuation requirement, how it changes the common stock FMV calculation, what happens to existing underwater options, how compliant repricing works, and what your board must do and when.

What Is a Down Round and Why Does It Matter for 409A?

A down round is a priced equity financing in which the new preferred shares are issued at a per-share price lower than the price paid in the company's most recent prior round. If Series A preferred shares were issued at $2.00 per share and the Series B prices at $1.20 per share, the Series B is a down round. The company raised new capital, but at a lower implied valuation than before.

Down rounds happen across the startup lifecycle but have become more frequent in environments of rising interest rates, compressed revenue multiples, and tighter venture capital deployment. They are not automatically fatal — many companies have navigated down rounds and gone on to successful exits. But they create a cluster of legal and financial consequences that must be addressed deliberately.

For 409A purposes specifically, a down round matters because:

• The new preferred price is an arm's-length transaction. It represents what sophisticated investors agreed to pay for equity in your company right now. This is the anchor data point for the Backsolve method under the AICPA Accounting and Valuation Guide.
• It constitutes a material event under Treasury Regulation 1.409A-1(b)(5)(iv)(B). This regulation specifies that an IRS safe harbor appraisal loses its validity when a material event occurs that would reasonably be expected to affect the company's FMV. A priced down round is the clearest possible example of such an event.
• It changes the liquidation waterfall. Down rounds typically restructure the economic rights of the preferred and common stock in ways that further suppress common stock FMV, independent of the lower enterprise value implied by the new price.

The net result: your existing down round valuation analysis from before the financing is no longer valid for granting new options, and a new one is mandatory before the board approves any further equity grants. For a broader understanding of what events require a new 409A, see our guide on material events for 409A.

Does a Down Round Trigger a New 409A Valuation?

Yes — with very limited exceptions. A priced down round is among the most unambiguous triggers for a new 409A valuation down round requirement. Treasury Regulation 1.409A-1(b)(5)(iv)(B) establishes that a qualifying independent appraisal provides a presumption of reasonableness for 12 months from the appraisal date — unless a “material event” has occurred that would reasonably be expected to affect the FMV. The IRS and the AICPA are clear that a new arm's-length priced equity transaction is the paradigmatic example.

The only scenarios in which you might argue a down round does not invalidate a prior 409A are narrow and rarely applicable:

• De minimis raise. If the down round is extremely small relative to the company's total enterprise value and the price reduction is modest, a conservative argument could be made that the event is not material. In practice, any down round large enough to constitute a genuine financing event will almost certainly meet the materiality threshold.
• Inside round with non-arm's-length terms. An inside round priced below the prior round but on terms that are demonstrably not arm's-length — for example, a rescue bridge from existing investors at an administratively set price — creates factual complexity. Your valuation provider and legal counsel will need to evaluate whether the new price represents a genuine market indication of FMV.

Outside these narrow carve-outs, the rule is straightforward: close a down round, get a new 409A before granting options. No grace period applies.

How a Down Round Changes Your Common Stock FMV

The post-down-round common stock FMV is almost always lower than the common stock FMV implied by the prior round — and it is typically lower by a larger margin than the simple reduction in preferred price suggests. Understanding why requires understanding how a down round valuation is constructed.

The standard methodology for an early- to growth-stage company with a recent financing is the Backsolve method under the Option Pricing Model (OPM). The Backsolve takes the new preferred price as the anchor, derives an implied enterprise value, and then allocates that enterprise value across all security classes using a Black-Scholes-based OPM framework that models the economic rights of each class in different exit scenarios.

Three factors cause common stock FMV to fall more steeply than the preferred price in a down round:

• Lower aggregate enterprise value. The new preferred price implies a lower total company value. When the OPM distributes that smaller pie across all security holders, common stock — which sits at the bottom of the waterfall — receives less.
• Anti-dilution adjustments. Most preferred stock is issued with broad-based weighted-average or full-ratchet anti-dilution protection. When a down round closes, prior preferred holders receive additional shares (or an adjusted conversion ratio), increasing the total shares that rank ahead of common and further diluting common on a per-share basis.
• Increased aggregate liquidation preference. New preferred shares issued in the down round add a new layer of liquidation preference above common. More capital must be returned to preferred holders before common stock participates in any exit proceeds.

In severe down rounds — where the new round prices at a 40–70% reduction from the prior round — it is not unusual for common stock FMV to fall to 5–15% of the new preferred price per share. In extreme cases involving very large aggregate liquidation preferences, the common stock FMV can approach zero.

This is the technical reality that makes down round compliance so consequential: the FMV of common stock, and therefore the minimum permissible strike price for new options, may be dramatically lower than founders and employees expect. For a deep dive into how the methodology works, see our guide on 409A valuation methodology.

The Anti-Dilution Adjustment Problem

Anti-dilution protections are a standard feature of venture-backed preferred stock. They are designed to protect investors from dilution when a company raises capital at a lower valuation than prior rounds — exactly the scenario a down round creates. But while anti-dilution adjustments serve a legitimate investor protection function, they also create significant complexity for the post-down-round 409A analysis.

Weighted-Average Anti-Dilution

Broad-based weighted-average anti-dilution is the most common structure in venture-backed companies. When a down round closes, the conversion ratio for prior preferred holders is adjusted upward using a formula that blends the old price with the new price, weighted by the number of shares outstanding. The result: prior preferred holders receive more common shares on conversion, diluting the common stockholder pool without issuing new preferred shares.

In the 409A model, these anti-dilution adjustments must be reflected in the fully-diluted share count and in the OPM breakpoints. Failure to account for anti-dilution adjustments produces an overstated common stock FMV — a dangerous analytical error.

Full-Ratchet Anti-Dilution

Full-ratchet anti-dilution is more aggressive: it resets the conversion price of prior preferred shares to the price of the new down round, regardless of the size of the new issuance. Full-ratchet provisions are less common in modern venture deals but do appear, particularly in bridge financings and inside rounds.

When full-ratchet provisions apply, the increase in fully-diluted share count and the suppression of common stock value can be severe. The post-down-round 409A valuation down round analysis must model the exact post-adjustment cap table, including all converted share counts and updated conversion ratios, to produce an accurate common stock FMV. Your valuation provider needs the complete certificate of incorporation with any amendments, as well as confirmation from legal counsel about which anti-dilution provisions were triggered and what the adjusted conversion ratios are.

Stock Option Repricing After a Down Round

When a down round significantly reduces the FMV of common stock, many outstanding options become deeply underwater — their exercise price is higher than the current FMV. Employees holding these down round stock options have no economic incentive to exercise and may feel their equity compensation has become worthless. Boards often consider repricing as a retention tool.

Down round repricing options is legal and, when structured correctly, does not trigger additional Section 409A liability. The key structural requirements are:

• New exercise price at or above current FMV. The repriced exercise price must equal or exceed the FMV of common stock as determined by a current, qualifying 409A valuation. Setting the new price below FMV converts the repriced option into a discounted stock option subject to Section 409A penalties.
• No extension of the original option term. Repricing cannot extend the term of the original option grant. Extending the term could constitute a new grant under Treasury Regulation 1.409A-1(b)(5)(v)(C), potentially creating a new Section 409A compliance obligation.
• No addition of deferral features. The repricing cannot add features that allow the option holder to defer receipt of income beyond exercise, such as deferred settlement provisions.
• Board resolution required. The repricing must be approved by the board of directors and documented in a formal board resolution specifying the affected options, the old exercise price, the new exercise price, and the FMV basis for the new price.

There are also important securities law and accounting considerations. A repricing of options held by reporting persons (directors and executive officers) requires shareholder approval under most state corporate laws and stock exchange rules. Under ASC 718, a repricing triggers incremental compensation expense equal to the increase in the fair value of the repriced award compared to the original award immediately before repricing.

Section 409A Penalties When Strike Price Exceeds FMV

The penalty framework under IRC Section 409A is designed to be punishing. When an option is granted with an exercise price below FMV — which can happen inadvertently after a down round if new grants are made against a stale 409A — the option is treated as nonqualified deferred compensation. The consequences are immediate and severe.

The critical point is that income is recognized in the year of vesting — not exercise. An employee who receives a discounted option grant may face a tax liability well before the option has been exercised or any cash has been received. This creates a serious hardship: the employee owes tax on notional income from an option they have not yet exercised and may not be able to exercise.

These penalties apply with equal force whether the discounted option was granted intentionally or by mistake. This is why down round compliance is not a formality — it is a direct financial protection for the people on your team. Reviewing common 409A mistakes founders make in this area is worth doing before your next grant cycle.

Down Round Valuation Methods: What Changes

The 409A valuation down round analysis uses the same general methodological framework as any other 409A — the AICPA Accounting and Valuation Guide prescribes the acceptable approaches — but the specific inputs and the dynamics of the model change substantially.

Backsolve Method (OPM Backsolve)

For most post-down-round 409A valuations, the Backsolve method is the primary approach. The new preferred share price anchors the model: the valuator derives the implied enterprise value consistent with the new preferred terms, then allocates that enterprise value across all security classes using the OPM. The OPM models the payoff to each class of security as a series of call options on the enterprise value, with breakpoints defined by the liquidation preferences, anti-dilution adjustments, and participation rights of each class.

Key inputs that change materially in a down round scenario:

• Implied enterprise value. Lower than the prior round, anchored by the new preferred price and the post-closing fully-diluted share count.
• Adjusted cap table. Must reflect all anti-dilution adjustments triggered by the down round, any new preferred shares issued, and any changes to conversion ratios.
• Updated liquidation waterfall. The new preferred tranche adds a new layer, and prior preferred tranches may have adjusted liquidation preferences depending on their anti-dilution adjustment terms.
• DLOM (Discount for Lack of Marketability). Post-down-round, exit uncertainty typically increases, which can increase the DLOM applied to common stock. A higher DLOM further depresses common stock FMV.

PWERM Considerations

If the company has specific near-term liquidity scenarios under active consideration following the down round — an acquisition process, a potential structured exit, or a planned follow-on round at defined terms — the Probability-Weighted Expected Return Method (PWERM) may be appropriate alongside or instead of the Backsolve. The PWERM assigns probabilities to each exit scenario and calculates the common stock value under each.

Post-down-round PWERM analyses often assign higher probability weights to dissolution and structured exit scenarios than a pre-down-round analysis would, reflecting the increased business risk. These higher dissolution probabilities suppress common stock FMV further. For additional context on how stage-specific dynamics affect the methodology, see our guide on 409A valuations at Series B and Series C.

Board Obligations and Compliance Timeline

The board of directors carries the primary fiduciary responsibility for ensuring that stock option grants comply with IRC Section 409A. In the context of a material event down round, this responsibility becomes especially acute because the gap between the old FMV and the new FMV may be large, and the temptation to delay the new valuation can be significant.

The compliance timeline the board should follow:

• At term sheet execution: Engage a qualified independent appraiser to begin preparing the post-close 409A. Provide the appraiser with the draft term sheet so they can begin modeling the new capital structure.
• At close: Provide the appraiser with the final executed financing documents, the updated cap table, the certificate of incorporation as amended, and confirmation of all anti-dilution adjustments. Impose a moratorium on new option grants until the 409A is complete.
• Within 5–15 business days of close: Receive the completed 409A report from the appraiser. Review and approve the FMV conclusion at a board meeting. The board approval should be documented in board minutes.
• At next grant approval: Use the new FMV as the minimum exercise price for all option grants. Document the 409A report reference, the FMV conclusion, and the grant date in the board resolution authorizing the grants.

Boards should also document the decision to pause grants between close and 409A completion. This documentation demonstrates that the board was aware of the compliance obligation and took affirmative steps to fulfill it — relevant evidence in any future IRS examination or M&A due diligence review.

Note that a material event down round does not reset the 12-month clock retroactively — it invalidates the prior appraisal going forward. Grants made before the down round closed, when the prior 409A was still valid, are unaffected provided they were properly authorized at the time. Only new grants made after the close require the post-down-round 409A basis.

How to Protect Your Team Through a Down Round

Down rounds are morale events as much as financial events. Employees who joined based on an equity story may find that their options are deeply underwater, worth a fraction of what they expected, or in some cases nearly worthless. The board and leadership team have both a legal obligation and a human obligation to handle this well.

Actions that protect your team in a 409A valuation down round context:

• Communicate proactively and accurately. Employees will hear about the down round. Explain what happened, what it means for the cap table, and what the company is doing to address it. Silence creates anxiety and rumors that are usually worse than the reality.
• Complete the new 409A quickly. A fast turnaround on the post-down-round 409A allows you to begin making new grants at the new (likely lower) FMV, which can be a meaningful retention tool. New grants at a lower strike price restore the economic upside that underwater options no longer provide.
• Evaluate repricing carefully. If you decide to reprice, do it correctly: new exercise price at or above new FMV, board-approved, legal counsel reviewed, and properly disclosed. A botched repricing that inadvertently triggers Section 409A penalties helps nobody.
• Consider option pool expansion. Many down rounds include an expansion of the option pool as part of the new financing. If your round includes pool expansion, work with legal counsel to ensure the new grants from the expanded pool are documented and authorized with the correct post-down-round 409A basis.
• Brief key employees individually. For senior leaders and early employees with the largest option grants, a direct conversation about what the down round means for their specific situation — and what the path to recovery looks like — is more valuable than a company-wide email.
