Revenue & Net Income Trend

Last updated: Jun 17, 2026 3:06am (10d ago)
Revenue
The top line — total sales before any costs or taxes are subtracted. A measure of how much business the company is doing.
Net Income
The bottom line — profit left after subtracting all expenses, interest, and taxes from revenue. Reflects accounting profitability, but includes non-cash items like depreciation, so it isn't the same as cash earned.
Operating Cash Flow
The real cash generated by the day-to-day business — selling products, paying suppliers, collecting from customers. Calculated from net income by adding back non-cash items and adjusting for timing (unpaid bills, unsold inventory). When OCF consistently lags net income, the reported profit may not be converting to real money.

Magnite is showing a genuine business inflection. Revenue grew from $468M (2021) to $714M (2025), a ~11% CAGR, but the more important shift is margin: gross margin recovered from a 33.9% trough in 2023 to 62.7% in 2025, and operating margin swung from -25% to +13.7% over the same window. Net income turned from -$159M (2023) to +$144.6M (2025), and FCF compounded to $165.6M on $714M revenue (~23% FCF margin). OCF/NI of 391x reflects that NI just crossed zero — the cash was always there; GAAP earnings are finally catching up. Accruals at -8.2% of assets and Beneish M of -2.5 corroborate that earnings quality is clean.

The weaker side is the capital structure and per-share math. Diluted shares went from 136.3M to 153.8M (3.1% CAGR), SBC runs 10.7% of revenue, and buybacks recover only 25% of SBC — so per-share value is being quietly taxed even as the operating business improves. Net cash is slightly negative (-$22.9M) against $553M of liquid cash, meaning gross debt is meaningful; Altman Z of 0.83 flags that, though the model is unreliable for an asset-light ad-tech platform throwing off $165M FCF. Insider tape is informational rather than alarming — the June 'sales' are sell-to-cover paired with awards, with only modest discretionary selling and zero open-market buys.

Net: this looks like a maturing platform with real operating leverage and clean cash generation, held back from a higher grade by structural dilution and a balance sheet that is adequate rather than a fortress.

Strengths 3
m78
Genuine margin inflection
Gross margin rebuilt from 33.9% (2023) to 62.7% (2025); operating margin went from -25% to +13.7%. This is operating leverage on a ~11% revenue CAGR, not financial engineering.
m72
Strong, clean cash generation
FCF $165.6M on $714M revenue (~23% FCF margin), up from $97.5M in 2021. Accruals -8.2% of assets and Beneish M -2.5 indicate earnings are not being manufactured.
m55
Adequate liquidity for self-funding
$553M liquid cash and $165M annual FCF mean the business funds itself; it does not depend on capital markets.
Concerns 4
m65
Persistent per-share dilution
Diluted shares grew from 136.3M to 153.8M (3.1% CAGR), SBC is 10.7% of revenue, and buyback/SBC is only 25%. Equity holders absorb a structural ~3%/yr headwind that eats into the operating gains.
m40
Balance sheet is a constraint, not a cushion
Net cash is -$22.9M despite $553M of cash, implying meaningful gross debt. Altman Z 0.83 overstates risk for an ad-tech platform but the leverage is real.
m30
Volatile historical profitability
Net income was -$130M (2022) and -$159M (2023) before turning positive. The 2025 print is the first year of real GAAP profitability — durability of the inflection is not yet proven across a cycle.
m20
Insider tape mildly negative but not damning
28 sells / 0 buys over 12 months ($6.7M), but the recent tape is dominated by A-Awards, F-InKind tax withholding, and small sell-to-cover. No conviction open-market buying from insiders.
This is a credible mature_earner mid-inflection, not an elite compounder. The margin recovery and cash conversion are real and the earnings-quality signals are clean — I believe the operating story. What keeps me from calling it Strong is the per-share economics: 3.1%/yr dilution with buybacks only mopping up a quarter of SBC means shareholders are funding the comp plan, and the balance sheet is workmanlike rather than a moat. If management starts neutralizing SBC and the 60%+ gross margin holds for another two years, this graduates. Today it's a solid B.
Verify before trusting this (6)
  • Customer concentration — particularly CTV exposure to Netflix/Disney/major broadcaster deals disclosed in the 10-K
  • Gross debt structure, maturities, and covenants behind the negative net cash position
  • Whether the 2023→2024 gross margin jump (33.9%→61.3%) reflects a true mix/cost shift or a reclassification of traffic-acquisition costs
  • SBC trajectory and any plans to step up buybacks beyond the current 25%-of-SBC pace
  • Sustainability of CTV growth rate and take-rate as supply-path optimization pressures intensify
  • Composition of the $144.6M 2025 net income — any one-time tax benefits or deferred tax asset releases
Valuation / Mispricing
-40
Fairly Valued
edge √Σ 39 · risk √Σ 79 · conf 6/10
Price $18.55 vs deserved roughly $17-20 on a quality-adjusted, dilution-aware basis — essentially fair, no margin of safety. attractive below $15.00

The e2e synthesis lands at 'Reasonable Premium,' which lines up with where the tape is: ~$2.66B market cap on a business that just turned the operating-leverage corner but still carries a sub-scale balance sheet and ~3%/yr dilution. The Company-Quality lens grades this a Solid 35 — credible mid-inflection, not an elite compounder — so deserved value gets a modest quality lift but nothing that justifies a steep premium. Earnings quality is clean (no haircut), which is the one thing keeping me from marking it down further.

Against that, $18.55 looks like the market has already underwritten the bull narrative: pure-play CTV/programmatic plumbing, margin expansion, FCF inflection. To make money from here you need the platform-monopoly thesis to actually play out against Google/Amazon/Meta vertical integration — that's the priced-in assumption, and it's not conservative. I don't see a margin of safety, but I also don't see egregious overvaluation. This is the textbook 'good business the market understands' setup.

Cheap signals 2
m30
Clean earnings quality, no haircut
Earnings-quality signal is good (score 1) and cash conversion is strong — the reported margin recovery is real, so no downward adjustment to deserved value from accruals/quality games.
m25
e2e synthesis lands at 'Reasonable Premium'
The composite framework doesn't flag the stock as expensive — consistent with a fairly-valued read rather than a short.
Rich / priced-in 3
m55
CTV inflection already in the multiple
Stock has rerated on the operating-leverage turn; at ~$2.66B cap the market is paying for the bull case (neutral CTV plumbing, margin expansion) rather than discounting execution risk against Google/Amazon/Meta vertical integration.
m45
Dilution drag not fully respected by FV
3.1%/yr net dilution with buybacks only offsetting ~25% of SBC means per-share fair value should be ~3% lower each year — a real haircut to deserved price that headline composite methods tend to under-weight.
m35
Sub-scale balance sheet limits premium
Solid-not-Strong quality grade (35) reflects a balance sheet that can't absorb a cycle downturn the way a true platform monopoly could; deserved multiple should sit below pure-play SaaS comps.
Fairly valued. The business is genuinely better than it was 18 months ago and the CTV story is real, but at $18.55 I'm paying for that — there's no gap to exploit. I'd need it in the mid-$15s before the risk/reward gets interesting, because that's where dilution and balance-sheet constraints stop being free options for the bull. I don't short fair, and I don't buy fair — I wait.
Verify before trusting this (4)
  • CTV take-rate trend and Disney/Netflix-class publisher renewal terms — directly drives deserved revenue multiple
  • SBC as % of revenue and net share count trajectory — confirms whether dilution drag is improving
  • Forward FCF guide and any one-time items in recent EBITDA — separates inflection from cycle bounce
  • Customer concentration disclosure — bear case on consolidation needs sizing
General Sentiment
-4
Balanced
tail √Σ 82 · head √Σ 86 · conf 6/10

The market tape is genuinely neutral (regime score +11, VIX 17, S&P just 1.8% off highs), so there is no broad risk-off avalanche to crush MGNI right now, but with a beta of 2.31 any drift toward risk-off would land hard on this name. Macro is a mild headwind via 4.43% 10y rates pressuring unprofitable/low-margin ad-tech multiples, and MGNI sits in exactly the cohort that gets re-rated on rate shocks. Net macro: small headwind, not acute. The narrative is the prime force and it is genuinely two-sided: the CTV-plumbing bull story is intact and moderately durable, but the 'big-tech walled gardens are squeezing the middleman' bear thesis is the structural overhang that keeps a permanent discount on the name. Cult coefficient is low, so there is no momentum-mob bid to lean on. Analyst tone is constructively positive (18 Buys, consensus Buy, one upward revision to $20) but the consensus target $19.25 is only ~6% above spot, meaning the sell side is lukewarm in dollar terms even if Buy-rated. Momentum is strong-positive over 3y (+46pp) which is a real tailwind on the tape, but the 7% recent CAGR has cooled. Net: forces roughly offset.

Tailwinds 3
m55
CTV secular narrative still intact
The 'neutral plumbing of CTV ad spend' story remains the default frame and gives MGNI a durable bid whenever CTV ad data points are good. Moderate intensity, moderate durability.
m45
Analyst tone constructive, fresh upward revision
18 Buys vs 4 Sells and a recent revision up to $20 signal sell-side is leaning positive, providing a steady drumbeat of supportive notes.
m40
3-year momentum trend
+46pp outperformance over 3 years means the tape has been rewarding this name; trend-followers and CTV-thematic funds are positioned long, not short.
Headwinds 4
m55
Walled-garden squeeze narrative is the permanent overhang
Google/Amazon/Meta vertical integration is the bear story that caps multiple expansion; any headline about big-tech ad-stack consolidation hits MGNI disproportionately.
m50
Beta 2.31 into a fragile-neutral tape
Regime is neutral but only 2 days old and VIX is elevated vs 1y; if the tape rolls risk-off, a 2.31 beta high-growth ad-tech name gets marked down 2x the market move.
m35
Rate backdrop pressures ad-tech multiples
10y at 4.43% is a slow drag on long-duration ad-tech equity multiples; not acute, but a persistent ceiling on re-rating.
m25
Consensus target barely above spot
Target $19.25 vs $18.10 implies only ~6% upside in sell-side dollar terms; Buy ratings but tepid price implication signals limited narrative conviction.
Net read: roughly balanced with a slight tilt to headwind because of the high beta into a still-fragile neutral tape and the permanent walled-garden overhang. The CTV narrative and constructive analyst tone provide a real floor, but there is no euphoric bid here and no obvious catalyst to force a re-rating; meanwhile any whiff of risk-off or any big-tech ad-stack headline asymmetrically punishes this name. I would not lean on sentiment as a tailwind - treat it as roughly neutral and respect that a 2.31 beta means the next macro move matters more than the story does.
Verify before trusting this (4)
  • Any Google/Amazon/Meta ad-stack announcement that escalates the walled-garden squeeze narrative
  • CTV ad-spend data points from Roku, Trade Desk, Disney that ratify or break the bull story
  • VIX breaking above 20 or S&P breaking below recent support - would amplify on a 2.31 beta
  • Whether the upward target revisions broaden from one analyst to a cluster
The market-wide tape + this name's exposure to it (beta / sector / narrative durability). Context on the non-fundamental pressure — not a call on the business or the price. processId: detail-general-sentiment

Reviews the pipeline's own verdicts
Verdict Modestly overvalued — fair value $15-16 on normalized earnings and decelerating Q1 trends; wait for Q2 re-acceleration confirmation or a pullback below $15 before committing.

Looking at the raw quarterly trajectory first: Q1 2026 revenue of $164.4M is up just 5.5% YoY from Q1 2025's $155.8M, and net margin collapsed back to 2.7% from the headline-grabbing 59.9% in Q4 2025. That Q4 NI of $123.1M on $205.4M revenue is almost certainly a tax benefit or deferred tax asset release — operating margins don't swing from 6% to 60% organically in a quarter. Strip that out and trailing four quarters of "normalized" net income is closer to $40-50M, not the $144.6M annual figure. The TTM P/E of 16.8x is therefore misleading; on cleaner earnings, you're paying 50-65x. FCF of $165.6M on a $2.66B market cap is the more honest anchor — roughly 6.2% FCF yield, which is fine but not cheap for a 7% revenue grower with decelerating momentum.

The synthesis verdict of "Reasonable Premium" and the pre-flight's "pre-profit-platform" framing contradict each other in a revealing way. Pre-flight is closer to right: Magnite is not a mature earner despite the rule-based classifier's 0.9 confidence — three of the last four years showed GAAP operating losses, and 2025's $97.8M operating profit is the first real proof point. Calling this a mature earner because of one clean year ignores that the cumulative operating losses from 2021-2023 totaled roughly -$349M. The market-forces "neutral" call and the narrative layer's identification of moderate-intensity platform-monopoly storytelling are the most honest reads here. The bear case — Google/Amazon/TTD vertically integrating and squeezing the neutral middleman — is not hypothetical; it's already happening, and the 5.5% Q1 YoY growth print suggests it may be biting.

A careful contrarian would press on three things. First, the insider activity table shows ten transactions in a two-day window in June 2026 — eight awards and two sales, all identical lot sizes — this looks like routine RSU vest-and-sell mechanics, not informed selling, so the "Unusual Selling Activity" flag is probably overweighted. Second, the revenue deceleration is real: 2024 grew 7.8%, 2025 grew 6.9%, and Q1 2026 annualized is tracking ~5-6%. The CTV secular tailwind narrative requires acceleration, not deceleration, to justify a 3.3x EV/sales multiple on a low-moat intermediary. Third, the balance sheet tile shows "—" for total debt and equity, which is a real gap — Magnite carried roughly $360M in term loan debt as of recent filings, so the "$553M cash" figure overstates net liquidity. Net cash is closer to $190M, materially changing EV calculations the models leaned on.

I dissent partially from the "Reasonable Premium" synthesis. At $18.55, you're paying ~16x normalized FCF for a business with 6-7% top-line growth, a one-time tax-benefit-flattered earnings base, decelerating quarterly trends, and structural competitive pressure from companies with 100x its R&D budget. The bull case requires CTV mix-shift to re-accelerate growth to low double-digits and operating margins to expand from 13.7% toward 20%+ — plausible but unproven, and Q1 2026's 2.7% net margin is the opposite signal. Fair value on a sober 8% revenue CAGR with margins stabilizing at 15% operating gets me to roughly $15-16, suggesting the stock is 15-20% rich, not "reasonable." The asymmetry isn't there: upside to $24-25 on a CTV re-acceleration thesis vs. downside to $12-13 if growth slips below 5% and Google/Amazon take share. Wait for either a Q2 print that confirms re-acceleration above 8% YoY, or a pullback to $15 that builds in a real margin of safety. The models are anchoring too heavily on the 2025 annual snapshot and not enough on the Q1 2026 deceleration.

Reviews the Opus findings above
Verdict I agree with Opus — modestly overvalued at $18.55; however, I see fair value closer to $16-17, acknowledging the competitive landscape and growth deceleration, but giving more weight to cash flow stability.

In examining Magnite, Inc.'s financials, several patterns emerge that are noteworthy. The company's recent revenue growth is modest, with a 6.9% year-over-year increase in 2025 and a further deceleration to a 5.5% increase in Q1 2026 compared to Q1 2025. The sharp net income jump to $123.1 million in Q4 2025, followed by a significant drop to $4.4 million in Q1 2026, suggests that the Q4 spike was likely due to a non-recurring event such as a tax benefit, not organic operational improvement. The operating cash flow of $236.2 million and the free cash flow of $165.6 million indicate solid cash generation, yet these figures are juxtaposed with a slowdown in revenue growth and a modest net margin of 2.7% in the latest quarter.

I find myself in agreement with Opus's assertion that the Q4 2025 net income was likely inflated by a one-time financial event, distorting the company's earnings picture. His claim that the trailing P/E ratio of 16.8x is misleading is supported by the more realistic assessment of earnings, which when normalized, suggest a much higher effective multiple. This aligns with the observation that free cash flow provides a more reliable valuation anchor for Magnite, given the current growth trajectory and margin pressures.

However, I diverge from Opus on the classification of Magnite as a "mature earner." The narrative of a "pre-profit-platform" seems more fitting, considering the historical operating losses and the recent reliance on a single profitable year. The notion of a platform monopoly lacks robustness given the aggressive competition from major tech companies, which is likely to impact Magnite's market position and pricing power. Opus's insight into the insider selling activity as routine vest-and-sell transactions rather than strategic divestment is a valid counterpoint to the "Unusual Selling Activity" flag, which I agree may be overstated.

A careful skeptic might argue that both analyses are overly focused on past performance and not sufficiently on forward-looking potential. They might question the emphasis on deceleration in revenue growth without considering market dynamics or internal strategic shifts that could reignite growth. Additionally, skeptics would scrutinize the balance sheet's lack of clarity regarding debt and equity, which could obscure the company's true financial resilience.
