The Overview

When your car breaks, someone has to have the part. O'Reilly's entire business is being that someone — through a network of stores and warehouses close enough to get the part to a mechanic within hours. It sells both to people fixing their own cars and, increasingly, to professional garages.

It is very good at it. O'Reilly keeps about 52 cents of gross profit on every dollar of parts it sells, and earns roughly 46 cents of operating profit for every dollar of capital employed. Its suppliers effectively finance the inventory: O'Reilly takes about 300 days to pay them.

The company pays no dividend at all. Instead it buys back its own shares, relentlessly. Over five years the share count has fallen 19.5% — which is why profit per share grew 12.5% a year while sales grew 8.9%.

Here is the problem, and it is arithmetic. The cash the company has left after investment has fallen for three years running: $2.58 billion, then $2.03 billion, then $2.03 billion, then $1.59 billion. Meanwhile the money it spends on warehouses and stores has doubled to $1.17 billion.

And it still bought back $2.10 billion of shares last year — 132% of the cash it generated. The difference was borrowed.

That is a deliberate, long-standing policy and it has made shareholders a great deal of money. It also means the company's balance sheet shows negative shareholders' equity of $763 million, and that a third of the earnings growth depends on borrowing continuing to be available and cheap.

Two things about the data itself are worth reporting, because they are unusual.

The company's own insider-transaction file contains a record dated 13 July 2027 — eleven months from now. That cannot have happened. We found the answer in a regulatory filing: the company hired a new supply-chain chief effective 13 July 2026 and granted him options that day. The year in the data feed is wrong by exactly one.

And the data feed contains no breakdown of the business at all — one line covering 100% of sales, and nothing by geography. So we cannot tell you how the professional half is performing against the do-it-yourself half, which is the most important operating question about this company.

The shares cost $91.83, about 25 times what analysts expect for 2027. Our fair value estimate is $95 — about 3.5% higher. Analysts on average say $107.77.

Putting a number on it: our fair-value estimate is $95 against a current price of $88.50 — real upside if our numbers are right.

Our summary metrics

Downside Risk (lower = safer)6/10High

"Rated 6 — an outstanding retail operator with a deliberately levered, dividend-free capital structure and a free cash flow line that is deteriorating. The supports: a 51.64% gross margin and a 19.56% operating margin on automotive parts; return on invested capital of 34.3% and return on capital employed of 46.5%, both among the best in this batch; interest coverage of 14.4x; a beta of 0.513, the second-lowest here; and a demand profile that is genuinely counter-cyclical, since an ageing vehicle fleet requires more repair when consumers defer replacement. Against that, five exposures. ONE, shareholders' equity is MINUS $763.4 million and retained earnings MINUS $2,328.8 million — the arithmetic residue of $10.6 billion of repurchases across four years — which voids six ratios and is addressed with its mechanism rather than reported. TWO, free cash flow has FALLEN in each of the last three years, from $2,584.9M (FY2022) to $2,027.8M to $2,026.2M to $1,593.2M (FY2025), a 38.4% decline, while capital expenditure doubled from $563.3M to $1,168.8M. THREE, the fiscal 2025 buyback of $2,097.0 million was 132% of free cash flow and was therefore debt-funded; total debt rose to $8,491.5 million. FOUR, there is no dividend at all — the entire shareholder return is a repurchase the company is borrowing to fund. FIVE, `currentRatioTTM` is 0.752 and `quickRatioTTM` is 0.128, because $5,731.4 million of inventory sits against $8,775.8 million of current liabilities; that is a working-capital structure that depends on supplier credit, with days payable of 300."

Growth Quality6/10High

"Rated 6 — steady, unspectacular, and entirely dependent on store count and price. Revenue: $11,604.5M (FY2020), $13,327.6M, $14,409.9M, $15,812.3M, $16,708.5M, $17,782.0M (FY2025) — an 8.9% compound rate over five years, decelerating to 6.4% in the most recent year. Diluted EPS: $1.65, $2.18, $2.34, $2.69, $2.71, $2.97 — a 12.5% compound rate, of which a large share is the share count falling from 1,063.7 million to 855.9 million, a 19.5% reduction. So roughly a third of the earnings growth is arithmetic rather than operational. Operating margin has drifted DOWN from a peak of 21.98% in FY2021 to 19.46% in FY2025, which is unusual for a business with this pricing position and is the clearest sign that the dual-market strategy is costing something. The current year is running better: first-half 2026 revenue of $9,452.6 million is up 9.2% on $8,662.0 million, with second-quarter operating income up 7.8%. Consensus wants revenue of $19,105.6M (FY2026, 19 analysts), $20,252.4M (FY2027, 19) and $21,497.3M (FY2028, 11) — 7.4%, 6.0% then 6.1% — with EPS of $3.280, $3.650 and $4.042, roughly 11.3% then 10.8%. What holds this at 6: the top line grows at 6-7%, the margin is drifting down, and the earnings growth premium comes from a buyback the company is now borrowing to fund."

Exponential Potential2/10Low

"Rated 2 — a superb retail operator with no exponential characteristic. O'Reilly sells automotive parts through a store network to both do-it-yourself customers and professional service providers — the 'dual market strategy' the 10-K names — and its advantage is availability: the right part, close by, today. That requires an expensive distribution network, which is precisely where the capital expenditure has been going, doubling from $563.3 million to $1,168.8 million in three years. The one knowledge-base claim in existence describes the category correctly — 'best-in-class retailers win by maniacal customer/employee focus over unit expansion; service and store experience protect the moat as merchandise commoditizes' — and names O'Reilly among five exemplars. That is a statement about execution quality, not about a growth curve. The demand driver is the size and age of the United States vehicle fleet, which grows at low single digits and is not sensitive to anything the company does. The genuine long-run question is electrification, which reduces the number of serviceable parts per vehicle over decades; NO filing in this archive quantifies it and NO knowledge-base claim addresses it, which is a real analytical gap rather than an absence of risk. A 2: excellent execution, in a slow, permanent, gently threatened category."

Fair value$95 $75–$116
What does “fair value” mean?

Fair value is Synthos’s estimate of what one share is worth today, based on our model of the company’s future cash generation and the risks to it. It is not a price target or a prediction of where the stock trades next quarter — it’s the price where we think risk and reward are balanced. Above it, you’re paying for outcomes better than our base case; below it, the market is offering a margin of safety.

The model’s inputs and weightings are proprietary — they’re the product. What we publish is the output, plus an independent, public-math cross-check further down the page (“Check our number”) so you can judge it for yourself.

What do the 5 tiers mean? (Core · Tactical · Watch · Hold · Avoid)
Buy — CoreOwn it as a foundation — start or add now, size it for years, let dips be gifts.
Buy — TacticalGood price + confirmed trend + a defined exit — buy the setup, not a marriage.
WatchWe want the business, just not at this price/setup — act only when the listed trigger hits.
HoldFine to keep if you own it — no reason to buy more; new money does better elsewhere.
AvoidDon't own it — the problem is the business or the expectations, so a cheaper price won't fix it.

"O'Reilly closed 2026-08-04 at $91.83, up 2.31% or $2.07, on 6,052,978 shares. It opened at $89.07, ranged $88.445 to $92.02, and closed within 0.2% of the day high — a strong session with no company-specific filing behind it. The technical position is a stock recovering into resistance: 14.8% below the 52-week high of $107.82 and 11.0% above the low of $82.73, 4.0% ABOVE a 50-day average of $88.26 but 1.3% BELOW a 200-day average of $93.00, with MACD at +0.61 and RSI at 69.05 — the HIGHEST reading in this batch and within a point of the conventional overbought threshold. Twelve-month return is MINUS 7.4% against SPY's +24.3%, with six-month −6.3% and three-month −2.3%, so the underperformance is persistent but shallow and the maximum drawdown from peak was only 14.8%. The most recent print, on 2026-07-29, was the weakest of the last five: adjusted EPS of $0.86 MISSED the $0.862 consensus by 0.2% — the second miss in five quarters — while revenue beat by 0.6%. First-half 2026 revenue of $9,452.6 million was up 9.2% year on year, which is the strongest half in the file."
What we’re watching
"The 2026-10-28 print against a consensus of $0.91 and $4,994.0 million. Within it: whether operating margin, which has drifted from a 21.98% peak in fiscal 2021 to 19.46% in fiscal 2025 and 20.15% in the June quarter, stabilises. Whether capital expenditure keeps rising — it doubled from $563.3 million in fiscal 2022 to $1,168.8 million in fiscal 2025 and the 10-K describes a strategy requiring capital 'to expand distribution infrastructure'. Whether the buyback continues at the fiscal 2025 rate of $2,097.0 million, which was 132% of free cash flow and therefore debt-funded. Whether RSI at 69.05 and a price 1.3% below the 200-day average resolve upward or reverse. And the new Chief Supply Chain Officer, appointed effective 2026-07-13 from a comparable retailer, whose remit is 'merchandise, inventory management, distribution operations, and transportation' — the exact functions absorbing the capital."

Medium term 6-24 months

"The medium-term case is a high-return retailer compounding earnings at roughly 11% on 6% revenue growth, with the difference coming from a buyback that is now debt-financed. Consensus has revenue at $19,105.6 million (FY2026), $20,252.4 million (FY2027) and $21,497.3 million (FY2028) — 7.4%, 6.0% and 6.1% — with EPS at $3.280, $3.650 and $4.042, roughly 11.3% then 10.8%. The estimate distribution is tight: the FY2027 EPS range is $3.559 to $3.740, a 5.0% spread across 18 analysts. The operational engine is genuinely excellent — a 51.64% gross margin, a 34.3% return on invested capital and a 46.5% return on capital employed — and the demand is defensive, since an ageing vehicle fleet needs more repair when replacement is deferred. What complicates the medium term is the capital cycle. Capital expenditure has doubled in three years to $1,168.8 million, free cash flow has fallen 38.4% from its fiscal 2022 peak to $1,593.2 million, and the company nonetheless repurchased $2,097.0 million of stock in fiscal 2025 — 132% of free cash flow — taking total debt to $8,491.5 million. That is a deliberate policy and it has worked for a decade; it is also the reason shareholders' equity is negative $763.4 million and the reason the return depends on the market continuing to fund it."
What we’re watching
"Whether free cash flow stops falling. Three consecutive annual declines from $2,584.9 million to $1,593.2 million, on capital expenditure that doubled, is the single most important trend in the file and the 10-K states the strategy requires it. Whether the distribution investment produces the revenue and margin it is supposed to — the new Chief Supply Chain Officer's appointment on 2026-07-13 is the company's own signal that this is the priority. Whether operating margin stabilises above 19% after drifting down 250 basis points from its fiscal 2021 peak. Whether the buyback moderates toward free cash flow or continues to be debt-funded; net financial debt of approximately $5,823 million is 1.46x EBITDA on the corrected basis, which is comfortable, but it has risen every year. Whether the professional half of the dual-market strategy keeps gaining share — the payload provides NO segment split at all, so this is unobservable here. And whether electrification begins to appear in the numbers; nothing in this archive addresses it."

"Long-run O'Reilly is one of the best-executed retailers in the United States and the one knowledge-base claim in existence identifies the right reason: in a category where the merchandise commoditises, service and availability are the moat. The economics support it — a 51.64% gross margin on automotive parts, a 46.5% return on capital employed, and a 300-day payables cycle that means suppliers finance the inventory. The category is defensive: the United States vehicle fleet is large, ageing and expensive to replace, and deferred replacement increases repair demand. The company has compounded earnings per share at 12.5% for five years with no dividend and a relentless buyback that has retired 19.5% of the shares. Against that stand two long-run constraints and one unknown. The capital intensity is rising: capital expenditure has doubled in three years and free cash flow has fallen 38%, so the model now consumes more to grow the same amount. The buyback that supplies a third of earnings growth is debt-funded at 132% of free cash flow, which cannot continue indefinitely. And the unknown is electrification: an electric vehicle has far fewer serviceable mechanical parts, the transition is measured in decades, and NEITHER any filing in this archive NOR any knowledge-base claim quantifies the exposure. That is the most important gap in this dive and it is stated rather than glossed."
What we’re watching
"Whether the capital intensity normalises or is permanent. Whether the buyback moderates as leverage rises, and what happens to the earnings growth rate when a third of it stops. Whether operating margin recovers toward the 22% of fiscal 2021 or continues drifting toward 19%. Whether the professional service-provider half of the business — invisible in this payload, which provides a single-line segment block and no geography at all — keeps gaining share against the do-it-yourself half. Whether the vehicle fleet keeps ageing, which is the demand driver nobody controls. And whether the electrification transition ever becomes measurable: the correct time to worry about it is before it appears in the numbers, and neither the filings nor the knowledge base give this dive anything to work with. Leadership: Brad W. Beckham has been chief executive for a relatively short period and the company appointed a new Chief Supply Chain Officer from outside on 2026-07-13, which is the first senior external hire visible in this archive."

FY2025$17,782.0M+6.4%51.59%$3,460.6M19.46%$2.97855.9

Two observations.

First, the operating margin peaked in fiscal 2021 at 21.98% and has fallen 252 basis points since. Gross margin is essentially unchanged at roughly 51-52%, so the entire decline is in operating expense, which rose from $4,102.8M on $13,327.6M of revenue (30.8%) to $5,713.5M on $17,782.0M (32.1%). That is 130 basis points of operating-expense inflation on a stable gross margin — the cost of the distribution and service build-out, arriving before its benefit.

Second, the share count did the heavy lifting. Revenue compounded 8.9% and diluted EPS 12.5%; the difference is 207.8 million shares retired, 19.5% of the fiscal 2020 count. Note that the count ROSE in fiscal 2025, from 838.6 million to 855.9 million — the first increase in the series — which the quarterly data shows reversing (828.9 million in the June 2026 quarter).

The quarterly record, and the current year is running better:

QuarterRevenueGross marginOperating incomeOp. marginDiluted EPS
Q2 2025$4,525.1M51.42%$914.5M20.21%$0.78
Q3 2025$4,705.7M51.85%$976.1M20.74%$0.85
Q4 2025$4,414.3M51.79%$828.6M18.77%$0.71

Q2 2026$4,892.0M51.45%$985.7M20.15%$0.86

First-half 2026 revenue of $9,452.6M is up 9.2% on $8,662.0M — the strongest half in the file — while first-half operating income of $1,827.4M is up 10.4%. The margin is stabilising in the low twenties rather than continuing to fall, which is the constructive read on an otherwise unremarkable set.

No segment detail is available. seg_prod reports one line — "Automotive Aftermarket Parts Segment" at $17,781,992,000, exactly 100% of revenue — and seg_geo is an empty array. The 10-K describes a "dual market strategy" serving both do-it-yourself and professional service-provider customers, and the split between them is the single most important operating disclosure for this company. It is not in this payload and no filing in this archive supplies it in extractable form. This dive therefore cannot analyse the mix, and says so.

FY2025$2,762.0M$1,168.8M$1,593.2M$2,097.0M132%

Read the middle two columns together. Capital expenditure has more than doubled in three years, from $563.3 million to $1,168.8 million — a 107.5% increase — while operating cash flow FELL 12.3% from $3,148.3 million to $2,762.0 million. Free cash flow has therefore declined in each of the last three years, by a cumulative 38.4%.

And the buyback has continued regardless, at 102% to 155% of free cash flow every single year. commonDividendsPaid reads exactly $0 in all four years — O'Reilly has never paid one. Total debt rose from $7,841.0 million (FY2023) to $7,920.9 million to $8,491.5 million (FY2025), which is where the difference came from.

This is a coherent and long-established policy, not a mistake. A business earning 34.3% on invested capital and 46.5% on capital employed should borrow to buy its own shares, and O'Reilly has done so for a decade with excellent results. What this dive records is that the policy is currently consuming more than the business produces, at a moment when the business is producing less.

The capital-expenditure diagnostic is high but explicable. capexToDepreciationTTM reads 2.107, and the direct fiscal 2025 computation is $1,168.8M / $511.2M = 2.29x. A ratio above 2 means the asset base is growing fast, and the 10-K states the strategy directly: it "requires capital to maintain and enhance our existing stores, invest to open new stores, fund strategic acquisitions, expand distribution infrastructure, develop enhanced information technology systems and tools." No corruption signature is tripped — capex is not zero, not positive-signed, not below 0.15 of depreciation, and the four-year progression from $563.3M to $1,168.8M is smooth and directional. The ratio is genuinely high because the company is genuinely building.

The company's own free cash flow definition differs from ours and is worth noting. The 10-K defines it as "net cash provided by operating activities less capital expenditures, excess tax benefit from share-based compensation payments, and (return of)/investment in tax credit equity investments." This dive uses the standard operating-cash-flow-minus-capital-expenditure construction throughout and states the difference.

Corrected leverage. totalDebt of $8,491.5M is filed long-term debt of $6,016.9M plus $2,474.6M of lease obligations — a 29.1% inclusion, the largest in this batch. On the financial-debt basis, net debt is $5,823.1M, or 1.46x fiscal 2025 EBITDA of $3,986.5M, against the vendor's netDebtToEBITDATTM of 2.311x. Corrected enterprise value is approximately $81,924M against the vendor's $85,426M — a 4.1% overstatement. Interest coverage is 14.4x on either basis.

Negative equity, and it is rejected with the mechanism. Shareholders' equity is MINUS $763.4M and retained earnings MINUS $2,328.8M, produced by $10,607.0 million of share repurchases across the four years in the cash flow file against cumulative earnings well below that. Rejected: returnOnEquityTTM of −232.4%, priceToBookRatioTTM of −41.28, debtToEquityRatioTTM of −5.223, bookValuePerShareTTM of −$2.225, tangibleBookValuePerShareTTM of −$3.382, and grahamNumberTTM, which the payload returns as null. The deficit is SHRINKING — from −$1,739.3M (FY2023) to −$1,371.0M to −$763.4M — because earnings now exceed distributions. Return on invested capital (34.3%) and return on capital employed (46.5%) are used instead, and both are outstanding.

3. The corporate events, and the defect one of them resolves

A new Chief Supply Chain Officer, effective 2026-07-13. From the 8-K filed 2026-07-10:

> "O'Reilly Automotive, Inc. has appointed Colin Yankee as Executive Vice President and Chief Supply Chain Officer, effective July 13, 2026. In this position, Mr. Yankee will be responsible for all aspects of our supply chain operations including merchandise, inventory management, distribution operations, and transportation. Mr. Yankee, age 49, joins O'Reilly with more than 20 years of retail supply chain experience. Prior to joining O'Reilly, Mr. Yankee held the position of Executive Vice President, Chief Supply Chain Officer at Tractor Supply Company since February 2020..."

Compensation: base salary $700,000, annual incentive target 85% of base, an annual option award at 100% of base, and "a position level stock option award in connection with his hiring, with a grant-date fair value of $500,000, to be granted on July 13, 2026, and determined using the Black-Scholes option pricing model."

This matters twice over. First, it is the operating signal: the company has hired an external supply-chain executive from a comparable retailer to run exactly the functions absorbing its capital expenditure. Second, it resolves the payload's strangest defect.

THE FUTURE-DATED INSIDER RECORD. The payload's insider block contains:

DatePersonRoleTypeSharesPriceHeld after
2027-07-13Colin Yankeeofficer: EVP & CSCO(blank)14,279$87.280

2027-07-13 is ELEVEN MONTHS IN THE FUTURE. The transaction type is blank and the holdings field reads zero. A reader taking the payload at face value would have a transaction that has not occurred.

The 8-K supplies the answer: the option award was "to be granted on July 13, 2026." The year in the payload is wrong by exactly one, and the 14,279 shares at $87.28 is the sign-on option grant whose Black-Scholes value the filing puts at $500,000. The defect is small in dollar terms and large in principle: a date field off by one year in a Form 4 feed, in the only record concerning a newly-appointed executive officer, discovered only because the 8-K existed.

4. Valuation

At $91.83:

FY2026EFY2027EFY2028EFY2029E
Revenue$19,105.6M (19)$20,252.4M (19)$21,497.3M (11)$22,296.1M (5)

EPS range$3.210–$3.311$3.559–$3.740$3.865–$4.219$4.180–$4.336

Coverage is good on the near years — 18 analysts on both FY2026 and FY2027 EPS, with a 5.0% FY2027 spread — and thins to 8 on FY2028 and 6 on FY2029, which are used only as cross-checks.

est.ebitdaAvg and est.ebitAvg are rejected for the fixed-ratio fabrication signature. ebitdaAvg is exactly 23.01% of revenueAvg and ebitAvg exactly 20.37% in FY2024 through FY2030.

And the FY2023 estimate row is wrong by an order of magnitude, for a reason the payload does not disclose. It reports netIncomeAvg of $34,067,831,586 and epsAvg of $39.76851 against a delivered net income of $2,346.6 million and EPS of $2.69. $39.77 is approximately fifteen times $2.65 — O'Reilly executed a fifteen-for-one stock split, and the FY2023 estimate row was never adjusted for it while FY2024 onward were. The net income figure of $34.1 billion is 14.5x the delivered figure and is simply wrong on any basis. The historical rows of est are not usable; only the forward epsAvg values are, and only after the FY2025 verification below.

The forward epsAvg field itself verifies well: the FY2025 estimate of $2.97867 against a delivered $2.97 — a 0.3% difference — which is why it is the sole basis for valuation here.

4a. What today's price assumes (the inversion)

At $91.83 — 28.0x FY2026 consensus and 25.2x FY2027 — the price embeds:

4b. The return bridge (why the multiple moves)

Expected return over the next twenty-four months decomposes as: EPS growth (+23.2% cumulative, from FY2026E $3.280 to FY2028E $4.042) + multiple drift (roughly HELD at 24-26x on the then-forward year) + shareholder yield (+2.76% per year, entirely buyback) ≈ +11% to +14% a year if the base lands.

Our base of $95 applies 26.0x FY2027E, a modest expansion from today's 25.2x, and at an unchanged 25.2x the fair value is $92 — the current price. So the entire 3.5% base upside is eight-tenths of a multiple turn.

The important observation about this bridge is that the shareholder yield and the earnings growth are the SAME THING here, counted once. Roughly a third of the 11% EPS growth IS the buyback; adding a 2.76% "shareholder yield" on top would double-count it. Stripped of the repurchase, the underlying earnings growth is closer to 7-8% on 6% revenue growth — which is what a 25x multiple is actually paying for.

4c. Variant perception (where we differ, what would surprise)

Synthos fair values

All three anchors are multiples of the FY2027 consensus EPS distribution (mean $3.64996, low $3.55947, high $3.74045, 18 analysts), cross-checked against the observed twelve-month multiple range of 22.7x–29.5x.

Base is 3.5% above spot; asymmetry roughly 1.44:1 (18.3% down, 26.3% up), with a shareholder yield that is already inside the earnings growth and is not added again. A base under 5% and a payoff ratio under 1.5:1 is a Hold.

5. Knowledge base — one claim, and it is not about this company

Raw hits: 1. After a case-sensitive entity re-run: 1. Discarded: 0. Name-level claims on O'Reilly: 0.

The sweep ran ORLY, O'Reilly, O'Reilly Automotive and AutoZone plus free text on "o'reilly" and "auto parts" across all 52,021 distilled claims.

> 2023-05-01 · bullish · conviction 70 · horizon: principle · business_breakdowns · no named speaker · skill 1.0

> "Best-in-class retailers win by maniacal customer/employee focus over unit expansion; service and store experience protect the moat as merchandise commoditizes."

> — entities: Costco, Home Depot, TJ Maxx, O'Reilly, Best Buy

That is the entire lane.

It is a general principle about retail quality in which O'Reilly appears as one of five exemplars. It says nothing about the automotive aftermarket, nothing about the dual-market strategy, nothing about the capital cycle or the buyback, and nothing about electrification. It is three years old and carries speaker: null.

The practical consequence is identical to an empty lane and this dive treats it as one. There is no independent read on the business, no counterweight to management, and nothing to grade. This is the SECOND name in this batch on which the Synthos knowledge base contributes essentially nothing — the other being an insurance broker — and what the two have in common is that neither specialty retail nor commercial insurance distribution is a subject our transcript sources discuss. All three horizon confidence ratings are set to Low as a result, and the verdict rests entirely on the filings and the arithmetic.

The homograph test passed: zero case-insensitive-only matches, and the apostrophe in "O'Reilly" produced no false positives against the several public figures sharing the surname.

6. Data integrity

Seven findings and only one clean check. O'Reilly's payload is among the weaker ones in this batch.

CLEAN 1 — the capital-expenditure line trips no corruption signature and the elevated ratio is explained by the filing. $563.3M, $1,006.3M, $1,023.4M, $1,168.8M across four fiscal years — a smooth, directional progression. capexToDepreciationTTM of 2.107 against a direct fiscal 2025 computation of 2.29x. A ratio above 2 is high, and the 10-K states the strategy requires capital "to expand distribution infrastructure." Not zero, not positive-signed, not below 0.15, and the swing is explained. The datum passes. The implied share count of 828,714,455 also matches inc_q's 828,875,000 weighted diluted to 0.02%.

DEFECT 1 — an insider record is dated ELEVEN MONTHS IN THE FUTURE. The entry for Colin Yankee, EVP & Chief Supply Chain Officer, is dated 2027-07-13, with a blank transaction type, 14,279 shares at $87.28 and zero securities owned. The 8-K filed 2026-07-10 establishes that his appointment was effective 2026-07-13 and that a sign-on option award with a $500,000 grant-date fair value was "to be granted on July 13, 2026." The year is wrong by exactly one. This defect class — a future-dated transaction — has not previously been recorded in this programme, and it was only detectable because the 8-K existed.

DEFECT 2 — negative shareholders' equity voids six ratios, REJECTED with the mechanism. Equity of MINUS $763.4M and retained earnings of MINUS $2,328.8M, produced by $10,607.0M of repurchases across four years with no dividend. Rejected: returnOnEquityTTM −232.4%, priceToBookRatioTTM −41.28, debtToEquityRatioTTM −5.223, bookValuePerShareTTM −$2.225, tangibleBookValuePerShareTTM −$3.382, and grahamNumberTTM (null). The deficit is shrinking and is a deliberate capital-structure outcome, not distress. Return on invested capital of 34.3% and return on capital employed of 46.5% are used instead.

DEFECT 3 — totalDebt includes $2,474.6M of lease obligations, a 29.1% inclusion — the LARGEST in this batch. Filed long-term debt is $6,016.9M; totalDebt reads $8,491.5M. netDebt of $8,297.7M and netDebtToEBITDATTM of 2.311x both inherit it; on the filed financial-debt basis net debt is $5,823.1M and leverage is 1.46x. enterpriseValueTTM of $85,426M is approximately $81,924M corrected — a 4.1% overstatement.

DEFECT 4 — seg_prod contains exactly ONE line and seg_geo is EMPTY. The product block reports "Automotive Aftermarket Parts Segment" at $17,781,992,000 — precisely 100% of revenue — which is technically a correct tie and analytically useless. The geography block is an empty array. For a company whose central strategic question is the mix between do-it-yourself and professional customers, the payload provides no decomposition of any kind.

DEFECT 5 — the FY2023 estimate row was never adjusted for a fifteen-for-one stock split, and its net income figure is nonsense. It reports epsAvg of $39.76851 against a delivered $2.69 — approximately fifteen times — and netIncomeAvg of $34,067,831,586 against a delivered $2,346,581,000, a factor of 14.5. FY2024 onward are adjusted. The array switches basis between FY2023 and FY2024 with no marker. The historical rows of est are rejected; the forward epsAvg values verify well (FY2025 estimate $2.97867 against a delivered $2.97) and are the sole valuation basis.

DEFECT 6 — est.ebitdaAvg and est.ebitAvg carry the fixed-ratio fabrication signature. ebitdaAvg is exactly 23.01% of revenueAvg and ebitAvg exactly 20.37% in FY2024 through FY2030. Rejected.

DEFECT 7 — inc_q reports ZERO depreciation and amortisation for the June 2026 quarter, against $135,361K, $135,405K and $128,666K in the three preceding quarters. Rejected for that quarter; no quarterly EBITDA is computed.

Also noted: dividendYieldTTM and dividendPerShareTTM both read 0, which is CORRECT — O'Reilly has never paid a dividend and the field is an accurate absence rather than a defect. currentRatioTTM of 0.752 and quickRatioTTM of 0.128 are correct and are a feature of the model: $5,731.4M of inventory against $8,775.8M of current liabilities, with days payable of 300.1 against days inventory of 242.7, giving a negative cash conversion cycle of −48.4 days — suppliers finance the working capital. km_ttm and ratios_ttm are present and complete. quote.yearHigh/yearLow ($108.72/$82.59) against tech.hi52/lo52 ($107.82/$82.73), a 0.8% and 0.2% discrepancy; tech is used throughout.

Vendor composite rating — noted and partly void. C+ / 2 overall, with 5 out of 5 on return on assets and 1 out of 5 on return on equity and price-to-book. Both 1-scores are computed on the negative equity denominator rejected in DEFECT 2 and are meaningless.

Non-equity tripwire — checked and passed. ORLY is common stock, Nasdaq-listed since 1993-04-23. Price of $91.83 is not par-like; beta is 0.513; there is no dividend; volume was 6.05M shares (roughly $556M of turnover); the 52-week band of $82.73 to $107.82 is a 30% range. This is common equity.

7. Technicals

Today's move and what it does to the entry

ORLY closed 2026-08-04 at $91.83, up $2.07, closing near the high of the day. There is no company-specific filing dated 2026-08-04.

The honest read: today's move takes the entry from neutral to unattractive. RSI at 69.05 is the highest in this batch, the price is pressing against the 200-day average from below, and the base case is +3.5% — this morning it was +5.8%. Nothing about the business argues against owning it; the price offers no reason to start today.

8. Insiders — one officer exited almost entirely, plus two director sales

2026-05-29Thomas HendricksondirectorS-Sale1,200$88.3219,675

Total open-market sales: 88,395 shares for approximately $8.2 million, across one officer and two directors, within twelve days.

The reading, with the qualification that matters. Robert Allen Dumas, Senior Vice President of Eastern Store Operations and Sales, exercised 84,600 options at strikes of $17.12 and $17.98 and sold all 84,600 at $92.5977 the same day, ending with 1,782 shares — a 97.9% reduction in his reported position. The strikes are roughly 81% below the sale price, so the options are old and deeply in the money, and an exercise-and-sell is the mechanically rational way to monetise them. What is not mechanical is retaining only 1,782 shares afterwards. An officer ending with under $165,000 of stock after monetising $7.8 million is a materially reduced alignment, and it is reported as such without further inference.

Both director sales are small and unremarkable: 2,595 shares at $88.67 and 1,200 at $88.32, executed 3.4% and 3.8% below today's price. John Raymond Murphy retains 4,000 shares; Thomas Hendrickson retains 19,675.

All three sales were executed between 2026-05-18 and 2026-05-29 at $88.32 to $92.60 — a band straddling today's $91.83.

What the file does not contain: any purchase by anyone, and any transaction by Brad W. Beckham, the chief executive. The insider block is mildly negative and thin.

9. Verdict, kill-criteria and flip conditions

Hold.

The business is excellent and the price is fair, which is the least actionable combination in research. At $91.83 O'Reilly trades at 25.2x the FY2027 consensus of $3.650 on a business with a 51.64% gross margin, a 34.3% return on invested capital, a 46.5% return on capital employed, a negative 48-day cash conversion cycle in which suppliers finance the inventory, and a demand profile that strengthens when consumers defer vehicle replacement. Our base of $95 is 3.5% above spot with 1.44:1 asymmetry.

Four reasons for the Hold.

First, free cash flow has fallen for three consecutive years — $2,584.9M, $2,027.8M, $2,026.2M, $1,593.2M, a 38.4% decline — while capital expenditure doubled to $1,168.8M.

Second, the buyback that supplies roughly a third of the earnings growth is debt-funded at 132% of free cash flow, with no dividend as an alternative. Strip it out and the underlying growth rate is 7-8%, which is what a 25x multiple is paying for.

Third, the payload is unusually poor and the analysis is correspondingly constrained. No segment split, no geography, negative equity voiding six ratios, a 29.1% lease inflation in total debt, an unadjusted split in the estimate array, and an insider record dated eleven months in the future.

Fourth, and it is the structural one: the knowledge base holds ONE claim and it is not about this company. There is no independent voice on the dual-market strategy, the distribution investment, the buyback policy or electrification. On a name where the filings alone must carry the verdict, a base case of +3.5% is not enough margin to act on.

Pre-registered KILL criteria — what would take this to Watch or Avoid:

Pre-registered UPGRADE conditions — what would take this to Buy — Tactical:

Where ORLY sits in the Synthos Framework Portfolio. No new position. Where held, hold — a 0.513-beta retailer earning 46.5% on capital employed, in a category that benefits when consumers defer big purchases, is legitimate defensive ballast. On the watch list at $78 for a first tranche of 1.0% in the consumer sleeve. Logged as a tracked Synthos call (Hold) as of 2026-08-04 at $91.83, with the fair-value anchors, kill criteria and upgrade conditions all gradeable. The specific item to grade this dive on is the future-dated insider record: a Form 4 dated 2027-07-13 that the 8-K of 2026-07-10 resolves to 2026-07-13, which is a new defect class for this programme and was findable only because the filing archive existed.

Single biggest risk: the capital cycle, and specifically that the buyback is no longer self-financing. Capital expenditure has doubled in three years to $1,168.8 million, operating cash flow has fallen 12.3%, and free cash flow is down 38.4% to $1,593.2 million — and the company nonetheless repurchased $2,097.0 million of stock, 132% of what it generated, funded by debt that has risen to $8,491.5 million. Roughly a third of the 11% earnings-per-share growth the consensus expects is that repurchase. If it moderates to the level of free cash flow, growth falls toward 8% and a 25x multiple becomes hard to defend; if it does not, leverage keeps rising against a business whose cash generation is currently shrinking. Neither outcome is a crisis — net financial leverage is only 1.46x on the corrected basis and interest coverage is 14.4x — but both reduce the return, and the base case of +3.5% has no room to absorb either.
