Questions this testimony turns on
- What was the fair market value of the company or interest on the valuation date?
- Are the cash flow projections reliable, and why did the expert accept or reject management's forecasts?
- How was the discount rate built, including beta, size premium, and company-specific risk premium?
- Are the comparable companies or transactions truly comparable, and how many were used?
- Does the valuation measure the kind of value or loss the governing law allows?
Methods
- Discounted cash flow analysis
- Comparable company multiples
- Precedent transaction analysis
- Discount rate (WACC) estimation
How the testimony is attacked
- Subjective company-specific risk premium. Opponents argue the discount rate inputs were chosen to reach a result. In Buchwald v. Renco Group the court admitted the solvency expert's DCF, noting that company-specific premiums are necessarily somewhat subjective and are best tested on cross-examination.
- Thin set of comparables. Defendants attack a market approach built on too few comparable companies. In Acosta v. Vinoskey the court excluded the portion of an ESOP valuation that relied on a single public comparable while admitting the DCF analysis.
- Valuation that measures the wrong kind of loss. Defendants argue a DCF of expected future benefits measures lost profits that the claim does not permit. In Kortright Capital Partners v. Investcorp the court disregarded the plaintiffs' DCF damages model because New York law limits negligent misrepresentation damages to out-of-pocket loss.
- Rejection of management projections. Opponents argue the expert substituted his own forecasts for contemporaneous management projections. In Buchwald the expert explained why management's projections were unrealistic and built revenue from outside price forecasts, and the verdict based on his testimony survived post-trial motions.
- No peer review of the specific report. Defendants argue the particular valuation was never peer reviewed. The Acosta court held that Daubert asks whether the general method, such as DCF, has been peer reviewed, not the individual report.
What the public record shows
Courts have filed at least 25 opinions since 2015 that discuss this class of testimony and cite Daubert or Rule 702, as of October 2, 2026. Three that show how courts handle this class of testimony:
| Outcome | Case | Court | Year | Why |
|---|---|---|---|---|
| Excluded | Kortright Capital Partners LP v. Investcorp Investment Advisers Ltd.392 F. Supp. 3d 382 | S.D.N.Y. | 2019 | After a bench trial the court disregarded the plaintiffs' DCF damages testimony, and the defense rebuttal to it, because valuing the benefits a lost transaction would have produced is not a permissible measure of damages for negligent misrepresentation under New York law. |
| Limited | Acosta v. Vinoskey310 F. Supp. 3d 662 | W.D. Va. | 2018 | In an ESOP overpayment case the court admitted the government's DCF valuation but excluded the market-comparable component built on a single public company, treating the remaining objections as matters of weight. |
| Admitted | Buchwald v. Renco Group, Inc.539 B.R. 31 | S.D.N.Y. | 2015 | The court had denied the Daubert motion against the trustee's solvency expert, holding that challenges to his company-specific, size, and market risk premiums in the WACC went to cross-examination, and it denied a new trial after the verdict. |

In federal court: amended Rule 702
In federal court, since December 1, 2023, Rule 702 says expressly that the party offering an expert must show the court it is more likely than not that the testimony meets each requirement: that it rests on sufficient facts or data, uses reliable methods, and reflects a reliable application of those methods to the case. Questions about the basis of an opinion are no longer automatically matters of weight for the jury. For how the circuits have applied the amendment, see the Rule 702 tracker, which follows each court of appeals; for what that means for preparing or attacking this class of expert, see the guide on amended Rule 702.
