Value a consolidation by comparing the combined company's expected cash flows with the standalone baseline. Estimate incremental revenue created by the combination, subtract any incremental costs, and add avoidable costs over a defensible number of years. Keep the target's existing revenue stream separate from merger-specific benefits so decision-makers can see what they are actually paying for. Rover applied this approach rather than relying on claims that consolidation would earn a higher public-market multiple. Its model included reduced marketing competition and data-related improvements alongside DogVacay's existing revenue. The method forces every claimed synergy to have a mechanism, magnitude, duration, and uncertainty range. It also makes the thesis falsifiable after closing because actual revenue gains and savings can be compared with the original model.
Origin
Aaron Easterly explained that Rover modeled the DogVacay transaction as cash flow rather than assigning a vague strategic premium or assuming consolidation would produce a higher market multiple.
Core principles
- 01Model value through observable economic changes.
- 02Separate existing revenue from incremental benefits.
- 03Time-limit savings instead of capitalizing them indefinitely.
- 04Treat data and marketplace improvements as benefits only when their mechanisms can be specified.
How to run it
- 1
Build the Standalone Baseline
Forecast the buyer and target without the transaction. Include revenue, acquisition costs, operating expenses, and expected competitive pressure.
Pro tip Use the same time periods and accounting definitions for both businesses.
Watch out An inflated or inconsistent baseline will distort every synergy estimate.
- 2
Map Incremental Revenue
Identify revenue that exists only because of the transaction, such as higher conversion, improved retention, expanded liquidity, or cross-selling.
Pro tip Tie each revenue gain to a specific behavioral or operating mechanism.
Watch out Do not count the target's existing revenue as a synergy.
- 3
Map Incremental and Avoided Costs
Calculate costs added by integration and costs avoided through consolidation. Include marketing, systems, staffing, facilities, and migration expenses.
Pro tip Separate one-time integration costs from recurring savings.
Watch out Gross savings can look attractive while transition costs make near-term cash flow worse.
- 4
Choose a Defensible Horizon
Model each benefit only for the period in which it can reasonably persist. Account for new competitors and changing market conditions.
Pro tip Use multiple durations for uncertain benefits.
Watch out Do not assume a temporary reduction in competition lasts forever.
- 5
Compare Value with Consideration
Discount the modeled cash-flow improvement, apply uncertainty ranges, and compare it with the cash, equity, and risk being exchanged.
Pro tip Show how much deal value comes from each component.
Watch out A positive headline case is insufficient if reasonable downside cases destroy value.
In the wild
Rover modeled incremental revenue and cost savings rather than relying on a strategic valuation premium. Easterly said only about 15% of the deal's value came from DogVacay's existing revenue stream; other value included marketing savings and better data coverage.
→ The company could evaluate the transaction through explicit economic components instead of a hand-wavy multiple expansion thesis.
Two local marketplaces spend heavily on the same search keywords. A merger model compares their standalone acquisition costs with expected post-merger spending, subtracts migration costs, and limits the savings horizon to account for future entrants.
→ The buyer obtains a bounded estimate of marketing synergy rather than assuming permanent category control.
Common mistakes
Capitalizing Vague Strategic Value
A hoped-for valuation multiple increase is not a substitute for identifying the cash flows the transaction should change.
Double-Counting Existing Revenue
The target's current revenue and incremental merger benefits must remain separate components of the valuation.
Assuming Savings Last Forever
Competitive markets can attract new funding and entrants, so every saving needs a defensible duration.
Is it for you?
Best for
It is best for consolidation deals with identifiable revenue effects, marketing savings, operational savings, or data advantages.
Not ideal for
It is not ideal when the transaction is primarily exploratory and its benefits cannot yet be connected to measurable economics.

“So we modeled it as basically a cash flow. Like what is the amount of um incremental revenue minus incremental cost in the case where…”
“And it turned out that uh only about 15% of the value of the deal was dog vacay's existing revenue stream.”
“And so we got a decent amount of value from call it the economies of scale on the data side, in addition to the marketing…”
