Economic Damages Expert Witnesses

Commercial litigation frequently turns on quantifying the financial consequences of a breach of contract, business interruption, trade secret theft, patent infringement, or fraud, and disputes arise because parties often disagree sharply about how those consequences should be measured. A plaintiff and defendant may agree that a wrong occurred while disputing the extent of the resulting financial harm, whether measured as lost profits, diminished business value, or a reasonable royalty. These disagreements become contested because economic damages calculations depend on assumptions about causation, market conditions, and financial modeling methodology that are rarely straightforward. Because the underlying financial analysis is highly technical, courts routinely require independent expert testimony to determine whether a proposed damages calculation is sound.

Expert analysis in economic damages matters typically involves building or evaluating a financial model that isolates the loss attributable to the conduct at issue from losses caused by unrelated market or business factors. Experts apply accepted valuation and forecasting methodologies to calculate lost profits, diminished business or intellectual property value, or reasonable royalty damages, and they assess whether an opposing expert's model rests on defensible assumptions. This work directly supports causation and damages determinations by clarifying how much of a claimed loss is properly attributable to the alleged wrongdoing, and it frequently shapes litigation strategy by identifying the strongest and weakest components of a damages theory. Where a damages model is challenged under Daubert or a similar standard, a well-qualified economic damages expert can identify methodological flaws that undermine an opposing calculation.

Because damages methodologies vary significantly by case type, the right expert should have direct experience calculating damages in the specific context at issue, whether that involves lost profits, intellectual property valuation, or business interruption. Round Table Group's network includes forensic accountants, economics professors, and finance consultants who have testified extensively on damage modeling, trade secret theft, and patent infringement damages, and who are prolific authors on econometrics and valuation methodology. Having completed more than 75,000 expert searches for litigators, we help attorneys match a case's specific damages theory with an expert whose credentials will withstand scrutiny.

Kinds of Cases We Work On

Round Table Group helps our clients find a wide variety of Economic Damages expert witnesses for cases like:

01

Lost profits from breach of exclusive distribution

A regional distributor sued a consumer products manufacturer for terminating their exclusive distribution agreement roughly three years before its term expired, seeking lost profits for the remaining contract period. An economic damages expert built a but-for projection using the distributor's historical sales growth, gross margins, and regional market trends, cross-checked against the performance of the distributor's other, unaffected product lines over the same period. The expert's model, which also accounted for the manufacturer's own internal sales forecasts prepared before the termination, produced a lost profits estimate of several million dollars. That figure, supported by the manufacturer's own contemporaneous projections, became the anchor both sides used in mediation.
02

Lost going-concern value from a supply contract breach

A specialty food producer sued its sole ingredient supplier after an abrupt supply cutoff forced the producer to shut down entirely within a few months, seeking damages for the destroyed value of the business rather than lost profits alone. An economic damages expert valued the business as a going concern immediately before the breach, using a discounted cash flow analysis built on the company's pre-breach financial performance and industry growth benchmarks, and compared that to the company's liquidation value after the shutdown. The expert's analysis found the going-concern value substantially exceeded what the business's remaining assets ultimately recovered in liquidation, with the gap attributable to the sudden, unplanned nature of the closure. That valuation gap became the basis for the damages award after a bench trial largely adopted the expert's methodology.
03

Unjust enrichment damages in trade secret misappropriation

A specialty chemicals manufacturer sued a former joint venture partner after discovering it had used misappropriated formulation know-how to launch a competing product line generating tens of millions of dollars in revenue over several years. An economic damages expert calculated the defendant's profits attributable to the misappropriated technology, isolating the incremental margin associated with the stolen formulation from the defendant's broader, legitimately developed product portfolio. The expert found the competing product line's gross margins ran meaningfully higher than the defendant's comparable legacy products, consistent with the cost advantages the misappropriated formulation provided. That disgorgement calculation, rather than a lost-profits theory, became the primary damages figure presented at trial and was substantially reflected in the jury's award
04

Reasonable royalty damages for license scope breach

A technology licensor sued its licensee, alleging the licensee had deployed licensed software across a far broader range of its business than the license agreement's per-seat structure permitted, without paying the corresponding fees. An economic damages expert calculated a reasonable royalty for the unauthorized use based on the license agreement's own per-seat pricing structure, applied to the actual scope of deployment identified through the licensee's internal IT records. The expert found the licensee had deployed the software to roughly three times the number of licensed seats over a multi-year period. That calculation, grounded directly in the parties' own negotiated pricing, was largely adopted by the arbitrator in awarding back-royalties.
05

Lost profits from wrongful franchise termination

A multi-unit restaurant franchisee sued its franchisor for wrongfully terminating franchise agreements across a dozen locations, seeking lost profits for the remaining term of each agreement. An economic damages expert built location-by-location but-for profit projections using each unit's historical performance, regional market growth trends, and the performance of comparable franchise units that remained open. The expert's model accounted for planned capital improvements and staffing changes that were already underway before termination, adjusting projected margins accordingly. That granular, unit-by-unit approach supported a lost profits award covering the remaining term of the terminated agreements, adopted largely as presented by the arbitration panel.
06

Business interruption damages from an SLA breach

An e-commerce company sued its cloud infrastructure provider after a platform outage lasting roughly two days during a peak sales period, seeking lost profits and increased costs incurred to restore operations. An economic damages expert calculated lost sales during the outage window using the company's sales data from comparable prior periods, adjusted for the specific promotional calendar and seasonal factors in effect at the time, and separately quantified the incremental costs of the emergency remediation effort. The expert's model estimated lost profits in the mid-single-digit millions, with the seasonal adjustment increasing the figure meaningfully above what a simple historical average would have produced given the timing of the outage. That damages calculation was central to the settlement reached shortly before the scheduled arbitration hearing.
07

Lost merger consideration damages in a busted deal

After an acquirer walked away from a signed $220 million merger agreement citing a financing contingency the target argued had not actually failed, the target sued for damages measured by the value its shareholders would have received had the deal closed. An economic damages expert calculated the gap between the agreed merger consideration and the company's standalone value as an independent entity following the failed deal, using a discounted cash flow analysis reflecting the company's post-termination financial trajectory. The expert found the standalone value had declined meaningfully below the agreed merger price, driven partly by customer attrition triggered by uncertainty during the extended deal process. That valuation gap became the primary damages figure presented in the litigation, which settled for a substantial portion of the claimed shortfall
08

Antitrust overcharge damages between commercial buyers and a supplier cartel

A group of mid-sized manufacturers sued several of their component suppliers, alleging years of coordinated price-fixing had caused them to pay overcharges well above competitive market levels. An economic damages expert built a benchmark regression model comparing prices paid during the alleged conspiracy period to prices in a comparable but unaffected earlier period and to prices paid by buyers in an unaffected geographic market. The expert's model found overcharges averaging close to 15 percent above the benchmark prices during the conspiracy period, translating into tens of millions of dollars in aggregate damages across the plaintiff group. That regression analysis was central to the damages phase of the litigation and anchored the eventual settlement.
09

Construction delay and disruption damages

A general contractor sued a project owner for delay damages after owner-caused design changes extended a commercial construction project by several months beyond its contracted completion date, seeking increased labor, equipment, and overhead costs. An economic damages expert performed a measured mile analysis, comparing labor productivity during unimpacted project periods to productivity during the periods affected by the owner's design changes, to isolate the disruption's cost impact from other factors affecting the schedule. The expert found labor productivity dropped by roughly a third during the impacted periods compared to the unimpacted baseline, supporting a quantified disruption cost distinct from the extended-overhead delay costs claimed separately. That measured mile analysis was significant in the arbitrator's award, which adopted the expert's productivity loss calculation largely as presented.
10

Lost profits from breach of a requirements contract

A specialty packaging supplier sued a beverage company for breaching a multi-year requirements contract after the beverage company shifted the bulk of its packaging purchases to a competitor mid-contract, seeking lost profits on the volume it would have supplied under the agreement. An economic damages expert calculated lost profits using the beverage company's own historical purchase volumes under the contract, projected forward using the beverage company's disclosed sales growth over the remaining contract term, less the supplier's avoided variable production costs. The expert's model produced a lost profits figure in the high single-digit millions, which the beverage company's own board materials describing its packaging volume growth plans helped corroborate. That corroboration was significant in defeating the beverage company's argument that the projected volumes were speculative, and the case settled shortly after the expert's deposition.
