What MediaAlpha, Inc. told the SEC could break it.

MediaAlpha depends on a small group of Demand Partners (insurance carriers/brokers buying Consumer Referrals): its largest Demand Partner was 25% of 2025 revenue and its next largest 24%, with the top 20 representing 82% of revenue; because most partner agreements include no minimum transaction-volume commitments, these few partners can rapidly reduce or stop spending, and the concentration also raises credit risk — so loss or pullback by a top partner would materially hurt revenue.

“Our top 20 Demand Partners represented 82% and 72% of our revenue for the years ended December 31, 2025 and 2024, respectively.”

MediaAlpha derives a substantial majority of revenue from the property & casualty insurance vertical — 90.1% of total revenue in 2025 (up from 76.1% in 2024) — making it highly subject to P&C insurance business cycles: during 'hard' markets with elevated loss ratios, carriers prioritize profitability and cut customer-acquisition spending (often rapidly and without warning) until they obtain regulatory approval to raise premiums, directly reducing demand on MediaAlpha's platform.

“Revenue from our P&C insurance vertical accounted for 90.1% and 76.1% of our total revenue for the years ended December 31, 2025 and 2024, respectively.”

Under its Up-C structure, MediaAlpha owes payments to pre-IPO owners under a tax receivables agreement: if all Class B-1 units were acquired in taxable transactions at the December 31, 2025 share price of $12.95, the company estimates it could be required to pay approximately $163 million under the TRA; this contingent obligation (plus dividend restrictions and reliance on subsidiary distributions) is a meaningful claim on future cash flows.

“we estimate that the amount that we would be required to pay under the tax receivables agreement could be approximately $163 million.”

MediaAlpha's lead-generation marketplace is exposed to evolving consumer-protection and privacy regulation: the FTC's position under the Telemarketing Sales Rule (TSR) that consent for calls must come directly from the consumer rather than via a third-party lead generator (asserted in the 'FTC Matter') could reduce the volume of leads and calls supplied to its marketplaces or their profitability, and privacy laws such as the CCPA/CPRA could require changes to data practices and substantial compliance costs.

“calls under the TSR must be received directly from the consumer, rather than through a third party such as a lead generator, and the staff of the FTC continued to assert this position in the FTC Matter.”
