A Step-Change in Scale and Margin
QuinStreet closed fiscal 2026 with a fourth quarter that wasn't just a beat — it was a clear acceleration. Revenue grew 43% year-over-year to $373.9 million, adjusted EBITDA jumped 87% to $41.4 million, and the adjusted EBITDA margin expanded 270 basis points to 11.1%. For the full year, revenue topped $1.3 billion, up 18%, while adjusted EBITDA rose 38%. As CFO Greg Wong put it: “Over the past two years, we've more than doubled our revenue and more than quadrupled the adjusted EBITDA.” — Gregory Wong, Chief Financial Officer · 2026-08-06 The market took notice: the stock has rallied 72% in the last 90 days, even while the broader advertising complex has been volatile.
The revenue trajectory is striking against the company's own history. Revenue growth has been steady for years, but the recent quarter marks a clear inflection — the 43% print is roughly double the company's average growth rate over the prior two years. The gross margin, at 11.9% in the latest quarter, has recovered 2 points from a year ago, and operating margin turned positive at 3.0%, a beat relative to the prior year's loss.
Home Services: The HomeBuddy Multiplier
The biggest single driver of the acceleration was Home Services, which grew 88% to $141.6 million and now runs at more than $500 million in annualized revenue. The key was the integration of HomeBuddy, acquired late last year. Management was characteristically effusive but also quantified the progress: “The HomeBuddy integration and synergy capture programs have gone very well. We have strong demand from existing clients and existing verticals. We made good progress in opening up and beginning to build new verticals.” — Douglas Valenti, Chief Executive Officer · 2026-08-06 That's a meaningful expansion beyond the legacy home services business, which had been growing in the mid-teens.
This is not a new story — the acquisition was discussed on the prior call with similar optimism: “It's going extremely well, going certainly as we had predicted and, in some ways, better.” — Douglas Valenti, Chief Executive Officer · 2026-05-08 But the magnitude of the step-up in Q4 is new, and management sees more room:
We are early in the penetration and footprint of our addressable markets, which we estimate to be well over $100 billion per year in total opportunity.
They explicitly expect Home Services to grow faster than Financial Services in the first half of fiscal 2027, driven by the HomeBuddy contribution.
Financial Services: Durable Demand and Digital Shift
Financial Services remains the larger vertical (62% of revenue) and grew 24% in the quarter, with auto insurance up 37%. Doug Valenti framed the demand as durable: “The carriers are in an exceptionally good financial position. Their loss ratios are at a great margin. They are really hungry for demand.” — Douglas Valenti, Chief Executive Officer · 2026-08-06 That echoes prior commentary — a year earlier he'd said “very strong engagement, very strong interest, a lot of focus on the channel” — Doug Valenti, Chief Executive Officer · 2026-02-05 — but the current call adds a new nuance: carriers have already begun lowered rates in many markets, which is historically positive for shopping volume. Management pegged the overall digital/performance transition at only about 20% complete, implying a long runway.
Still, the growth is being driven more by carrier budgets than by share gains. As Valenti noted, “If you look at the others that have reported that are in that industry, we kind of all grew at very similar rates. So I don't think we or they took as much share as we did grow out our existing footprints.” — Douglas Valenti, Chief Executive Officer · 2026-08-06 That's a useful sector check — this is a rising tide, not just a QuinStreet-specific share shift.
AI: From Productivity to New Channels
A fresh theme this quarter is the breadth of AI applications across the business. Management highlighted coding, creative generation, contact-center pre-qualification, and analytics. “we're integrated with OpenAI in most of our verticals now” — Douglas Valenti, Chief Executive Officer · 2026-08-06 — a step up from the prior call, where OpenAI was described as an early pilot. Valenti also flagged the future potential: “We can see a path for those platforms, the LLMs, to being very big new channels of high-quality, high-intent, well-qualified media for our marketplaces.” — Douglas Valenti, Chief Executive Officer · 2026-08-06 That's the kind of next-leg narrative that can support a re-rating.
The AI capabilities are also supporting margin expansion. The company's headcount has barely moved in two years (from 902 to 928 employees) while revenue doubled — a productivity story that CEO Valenti directly attributes to AI and process improvements. The gross margin trend supports this: Gross margin at 11.9% is off its trough and improving, and management expects adjusted EBITDA margins to reach 10.3% for fiscal 2027, up another 160 basis points.
M&A: More Fuel to the Fire
Perhaps the most important new piece of forward-looking information is the M&A pipeline. Management said they have capacity and appetite for more deals, and “probably before the end of the calendar year, we're likely to close at least one more, maybe two.” — Douglas Valenti, Chief Executive Officer · 2026-08-06 That suggests the acquisition engine that brought in AmOne, Modernize, Aquavita, and HomeBuddy isn't slowing down. With the stock up 72% in 90 days, QuinStreet now has a stronger currency for dealmaking.
Valuation: More Room, But Not Cheap
After the rally, the stock trades at a far more reasonable multiple than history — Price-to-revenue is 0.6x, down from over 2x during the pandemic. Even with the recent pop, the market is not pricing in the full acceleration. If QuinStreet can deliver on the fiscal 2027 guide and the M&A pipeline, there could be meaningful upside.
The story is simple but powerful: a scaled performance-marketing platform benefiting from the secular shift to digital, with HomeBuddy integration as the near-term catalyst and AI as the margin multiplier. The record quarter and raised outlook make this a name-in-motion worth watching.
