O’Reilly Automotive: Negative Equity, Big Buybacks, 27x Earnings
O’Reilly Automotive spent $2.43 billion buying back its own shares in the first six months of 2026, at an average price of $91.17. The stock now trades near $84.71. So the average buyback dollar this year is sitting on a paper loss of about 7%, and the company has kept on buying anyway. That single fact says a lot about how management thinks, and it also explains why the balance sheet shows negative equity. The 10-Q for the June quarter gives the share count and price.
My view is that negative book value is a symptom here, not a diagnosis. O’Reilly’s shareholders’ deficit is what a very profitable retailer looks like after it returns more cash than it retains. It becomes a problem only if the profit that pays for the buybacks stops growing, and the price I would pay depends on how sure I am that it will not.
What a shareholders’ deficit really records
Book value is assets minus liabilities. Every share repurchased reduces equity by what the company paid, and every dollar of accumulated profit adds to it. Pay out more than you keep and the number goes below zero. A company can do that for years without stress if its cash flow is steady enough to service the debt it took on. According to the quarterly filing data I found, the deficit was about $1.07 billion at March 31, 2026, tiny compared with the $68.5 billion market value.
That is why the price-to-book ratio of -37.8 tells you almost nothing on its own. The five-year average is -92.6, so the ratio has been deeply negative for a long time and has moved around mostly because the share price moved. A negative ratio cannot be ranked against other stocks, and screens that filter out P/B below zero remove a company that earns 14% net margins on $17.8 billion of sales. I would rather look at what the cash did.
A quick check on the buyback arithmetic
Two and a half billion in six months is nearly the full-year 2025 net income of $2.5 billion. The company bought 26.7 million shares. Dividing the market value of $68.5 billion by the price gives roughly 810 million shares outstanding (my estimate), so six months of buying retired about 3.3% of the company. Repeat that pace for a year and a holder’s ownership share climbs by around 6% to 7% without a single extra dollar invested. That is the machine behind earnings per share growing faster than net income: net income rose about 7% in the June quarter to $715.1 million, per the company’s quarterly release, while EPS was $0.87 against $0.78 a year earlier, up roughly 12%. The underlying statements are on O’Reilly Automotive’s financials page if you want to check them.
Read that carefully. A quarter in which profit grew 7% produced per-share growth of about 12%, and the gap comes from a shrinking share count. It is real for a holder, but it is not the same as the business growing 12%. Anyone who values the stock on EPS growth alone should remember which part was financial engineering and which part was selling parts.
Selling parts to aging cars
The operating business is dull in the useful way. Revenue was $14.4 billion in 2022, $15.8 billion in 2023, $16.7 billion in 2024 and $17.8 billion in 2025. That is about 7% a year compounded from 2022, with no down year. The June quarter brought in $4.9 billion, up 8%, which the release puts at 8.1%.
Margins tell the same quiet story. Gross margin was 51.6% against 51.2% the year before, and the operating margin was 19%. A retailer that holds a margin above 50% at the gross line while growing is not discounting to win sales. Parts are bought when a car breaks, and cars are older than they used to be, so demand has a floor that most retail categories lack. For a contrast with retailers whose demand depends on fashion and traffic, see my ranking of five retail stocks.
Growth of this sort is also easy to overpay for. That is the price question.
What 27 times earnings asks of you
Trailing earnings are $3.15 a share, so at $84.71 the P/E is 26.9. The five-year average is 27.7, which means the stock is priced about where it usually is. Forward earnings of $3.42 put the forward multiple at 24.8, and the implied growth from trailing to forward is 9%.
Here is the tension. The shares are 22.1% below their 52-week high of $109 and only 3% above the low of $83, yet the multiple sits at its five-year average. Both facts are true because earnings kept growing while the price did not: the stock drifted down, the profit moved up, and the ratio stayed put. A market that is unimpressed with a company growing earnings near 10% is usually pricing in something. My guess is the concern is that the pace of growth will slow from where it has been, and possibly that repair demand softens in a weaker consumer year. I cannot verify that motive, so I treat it as a hypothesis.
| Metric | Value | Context |
|---|---|---|
| Price | $84.71 | 52-week range $83 to $109 |
| Trailing P/E | 26.9 | five-year average 27.7 |
| Forward P/E | 24.8 | forward EPS $3.42 |
| Price to book | -37.8 | five-year average -92.6 |
| Q2 revenue | $4.9 billion | up 8% year over year |
| H1 2026 buybacks | $2.43 billion | 26.7 million shares at $91.17 average |
| Analyst target | $109 | range $98 to $120, 18 analysts |
Wall Street is more optimistic than the tape
Eighteen analysts cover it, 89% rate it a Buy, and the average target of $109 sits 29% above the current price. Even the lowest target, $98, is 16% higher. When every published target is above the stock, one of two things is happening: the analysts are early, or the market sees a risk they are not modeling. Targets lag prices, so I lean toward the first and I still hold the second in mind.
Short interest is 3.3% of shares. That is small, though not zero. After the July 29 report the stock moved -3.6% on the day, against an average absolute move of 4.7% after earnings, so this was an ordinary reaction and not a panic.
How a holder could think about position size
Here is how I would think about it, as a hypothetical rather than a trade. A holder who likes the business but worries about the multiple has a simple lever: size. With a business this steady, a normal-sized position is defensible, and doubling it because of a cheap-looking chart is not. The stock sits near its 52-week low, but a low tells you where others sold, not where the value is. I made a related point in how I size a position when beta is high, and the same logic applies in reverse: a calm stock earns its place through patience, not through a big bet.
Something else keeps me measured. A stock that moved from $109 to $84.71 while earnings kept rising has already done the hard part of resetting expectations, yet the multiple has not compressed. If growth slows to 5% or so, the market will want a lower multiple, and 22 times $3.42 is about $75. That is the downside I would keep in mind, roughly 11% below the current price, and it is arithmetic, not a forecast.
When negative equity does turn dangerous
I promised a counter-case, and here it is. Negative equity is a warning when three things happen together: earnings stall, debt comes due at higher rates, and the company keeps buying back stock out of habit rather than from surplus cash. Then the buybacks are funded by borrowing, and the shrinking equity cushion offers no protection when profit dips. I cannot see the maturity schedule from the data I use, so anyone who wants to own this stock should read the debt note in the latest 10-Q on SEC EDGAR before relying on my view. My comfort comes from the pattern of profit and cash generation, not from a debt table I have not checked line by line.
A second scenario worries me less but deserves a mention. If the share price rises sharply, buybacks become less effective, since each dollar retires fewer shares. Today’s price near the bottom of the range is the good case for a company that buys back stock, and one reason management can keep the pace up without stress. It is also a reason not to assume the same EPS boost at a price 30% higher. Compared with how I described big bank capital returns, where regulators limit how much capital can be handed back, O’Reilly faces fewer external limits and therefore has to supply its own discipline.
The lines I would read next
Here is where I land. I do not mark the stock down for negative book value, and I do not buy it because of it either. At 26.9 times earnings with growth near 10%, it is fairly priced by its own history, and the extra return has to come from the price recovering toward the $109 average target or from earnings growing faster than the forward figure. Neither is guaranteed.
For the October report I would check two lines. Revenue growth staying at or above about 7% would confirm the demand story. Buybacks continuing without a jump in borrowing would confirm that they are funded by earnings. If revenue growth fell below 5% while buybacks stayed at $2 billion or more a half-year, I would start treating the negative equity as the warning sign I now think it is not.
