MNTN (MNTN) Stock: Why It Fell 40% on a Guidance Cut

Quick answer

MNTN traded at $6.27 at 4:42pm ET on Nov 4, 2026, down 39.5% from a $10.37 close, after it missed its own revenue guide, cut its outlook for the year and replaced its chief executive. Third-quarter revenue rose 15% to $80.3 million, short of the $86 million to $89 million it guided in August and a consensus of about $87.7 million, and the company lowered its full-year revenue guide to $311 million to $314 million from $347 million to $357 million. Chief financial officer Patrick Pohlen blamed "unforeseen execution problems in our go-to-market organization." The new fourth-quarter guide of $75 million to $78 million means revenue will shrink 10% to 14% from a year earlier. The shares had risen 6.6% during the regular session and fell as low as $6.01 within 15 minutes of the 4:05pm release.

Our view: Bearish through February 10, 2027, around when MNTN is expected to report the fourth quarter and give its first 2027 outlook. The case for the stock: MNTN ended September with $252.3 million of cash and no debt, more than half of its market value at the after-hours price; it is still profitable, with $7.7 million of third-quarter net income and a 79% gross margin; and trailing customers grew 32%, so the company describes a sales problem rather than lost demand. The case against: the fourth-quarter guide calls for revenue to fall and adjusted EBITDA to drop about two thirds from a year earlier, so the damage is to the run rate, not one quarter; a new chief executive who says the company needs "operational rigor" will set the 2027 outlook, which gives him every reason to guide low; and the 2027 consensus of about $417 million still assumes 33% growth from the new 2026 midpoint. We think the case against carries more weight into February. The price fell about 40%, but fourth-quarter adjusted EBITDA is guided down 64% to 72%, and estimates for 2027 have not been cut yet. We would move off Bearish if the stock closes back above $7.67, its lowest price since its May 2025 listing, if fourth-quarter revenue tops the $78 million top of the guide, or if management starts using the $100 million buyback it authorized in August. This is a view on direction over that window, not a recommendation to trade the stock.

Key takeaways

MNTN traded at $6.27 at 4:42pm ET on Nov 4, 2026, down 39.5% from a $10.37 close, after third-quarter revenue of $80.3 million fell short of its own $86 million to $89 million guide and it cut its full-year revenue outlook to $311 million to $314 million from $347 million to $357 million.
The company blamed "unforeseen execution problems in our go-to-market organization" and replaced chief executive Mark Douglas with board member Tony Weisman, effective Nov 2. Chief operating officer Christopher Innes also left.
The fourth-quarter guide of $75 million to $78 million is 10% to 14% below the $87.1 million of a year earlier, and its adjusted EBITDA guide of $8 million to $10 million compares with $28.1 million in the fourth quarter of 2025.
The problem looks specific to MNTN: AppLovin and Magnite, which also reported after the close, traded up 22% and 12% after hours.
Our view is Bearish through February 10, 2027: revenue is now guided to shrink, a new chief executive will set the 2027 outlook, and the 2027 consensus of about $417 million still assumes 33% growth from the new 2026 guide.

Nov 4, 2026: a sales miss and a new chief executive

MNTN opened at $10.02, made its session low of $9.96 in the first minute and reached its high of $10.735 at 10:16am. It closed at $10.37, up 6.6%, on about 982,000 shares, near the bottom of the range it had held since late September. The results came out at 4:05pm ET, with a webcast at 4:30pm. The stock traded at $8.44 by 4:05pm and $6.23 by 4:10pm, and touched $6.01 at 4:19pm. At 4:42pm it was $6.27, down 39.5%, below the $7.67 low of May 15, 2026 and every other price it has traded at since its listing.

What moved the stock:

Revenue missed the company's own guide. Third-quarter revenue of $80.3 million fell from $82.5 million in the second quarter. Growth has slowed from 25% in the first quarter to 21% and then 15%, on the basis that excludes the Maximum Effort business it sold in April 2025.
The year was cut by about $40 million. The full-year revenue guide fell 11% at the midpoint, to $312.5 million from $352 million, against a consensus of $352.3 million. Adjusted EBITDA for the year is now guided to $66 million to $68 million, from $96 million to $101 million, roughly flat with the $68.0 million of 2025.
The fourth quarter shrinks. The $75 million to $78 million guide compares with $87.1 million a year earlier. Subtracting the first three quarters from the old full-year midpoint, the August guide implied about $108 million.
Management changed. The board named director Tony Weisman president and chief executive on Nov 1, effective Nov 2, succeeding Mark Douglas, and chief operating officer Christopher Innes left the same day. Weisman said in the release: "What MNTN needs is operational rigor and I am here to instill a culture of accountability and flawless execution." Our explainer on CEO departures covers how a change that arrives with a guidance cut tends to trade.

The selling was specific to MNTN. AppLovin, which runs an advertising platform, and Magnite, a seller-side ad exchange with a large connected-TV business, also reported after the close, and by 4:43pm they traded up 21.8% and 11.9%. The Trade Desk was up 1.1%. At the regular close, before the drop, RSI(14) stood at 54, the shares sat 4.6% below their 50-day average and 4.0% above their 200-day average, volume ran 1.6 times its 20-day average, and the stock was 30.8% below its 52-week high. The rest of the session's movers are in today's biggest stock moves.

Bar chart of MNTN quarterly revenue in millions: Q4 2025 actual 87.1, Q3 2026 old guide midpoint 87.5, Q3 2026 consensus 87.7, Q3 2026 actual 80.3, Q4 2026 new guide midpoint 76.5

The numbers

Measure	Q3 2026	Q3 2025	Change
Revenue	$80.3 million	$70.0 million	+15%
Gross margin	79%	79%	Flat
Net income	$7.7 million	$6.4 million	+19%
Diluted EPS	$0.10	$0.08	+$0.02
Adjusted EBITDA	$19.9 million	$16.0 million	+24%
Active PTV customers (trailing twelve months)	4,373	3,316	+32%

Earnings of $0.10 a share were half the $0.20 analysts expected, and adjusted EBITDA of $19.9 million missed the company's $22 million to $25 million guide. Sales and marketing spending rose 11.5% to $23.8 million while revenue fell from the second quarter. The trailing customer count rose by only 148 in the quarter, against 351 in the second quarter and 242 in the first. Operating cash flow was $43.5 million for the first nine months, and cash rose to $252.3 million from $210.2 million at the end of 2025. Our guide to guidance changes explains why a cut to the rest of the year usually weighs more than the quarter itself.

The bull case

The balance sheet gives the new team time. At $6.27 the company is worth about $469 million, so the $252.3 million of cash covers more than half of it and the business is valued near $217 million, a little over three times the adjusted EBITDA it still expects for 2026. MNTN has no borrowings and generates cash. Our page on net cash per share shows how to work through that math. The company also says demand is intact: it named a marketing chief who spent seven years at The Trade Desk, a head of agency partnerships from Snap and a head of inside sales from Salesforce, and its integrations with Klaviyo, AppsFlyer and Tealium are recent. Insiders own about 51% of the stock, and only about 36.7 million shares float.

The risks

The run rate is the problem. A fourth-quarter adjusted EBITDA guide of $8 million to $10 million against $28.1 million a year ago says profits fall faster than revenue while the company keeps spending on its sales team. Analysts entered the report expecting about $417 million of revenue in 2027, and that figure will have to come down a long way, which our guide to earnings estimate revisions explains can weigh on a stock for weeks. The guide also came from a new chief executive in his third day, and a fresh team often resets expectations low and then again at the next report.

Our explainer on post-earnings announcement drift covers why stocks often keep moving in the direction of a large surprise for weeks afterward. Short interest was 9.65% of the float before the report, with about four days to cover, so short sellers buying back shares could cushion some of the fall. MNTN authorized a $100 million buyback in August and had not used it by Sept. 30.

What comes next

The fourth-quarter report is likely around February 10, 2027, the date of last year's report, and should include the first 2027 outlook under Weisman. Before then, watch for analyst target cuts, whether the stock can recover the $7.67 low it broke after hours, and any purchases under the buyback. Fourth-quarter revenue above $78 million would be the first sign the sales problems are fixed.

What is Dombey's view on MNTN stock?

Bearish through February 10, 2027, around when the fourth-quarter report and the 2027 outlook are expected. This is a view on direction over that window, not a recommendation to trade the stock.

What would change the view on MNTN?

We would move off Bearish if the stock closes back above $7.67, its lowest price since its May 2025 listing, if fourth-quarter revenue tops the $78 million top of the guide, or if management starts using the $100 million buyback it authorized in August.
