Revenue Accelerated on Commodities, the Core Waste Margin Went Backwards, and the Margin Guide Quietly Vanished

Results vs. Consensus

Two observations about the bar before the numbers are read. First, the adjusted EBITDA miss of 1.8% is larger than the EPS miss of 1.4%, which means the shortfall was operational and not a tax or share-count artifact. The margin line is where it concentrates: the implied consensus margin of 31.7% against a printed 31.0% is a 70 basis point gap on the one metric this company is bought for. Second, this is the first adjusted-EPS miss of our coverage period. The first quarter beat by 3.4% on an 18.4% tax rate and the second was in line to a penny ahead through a 150 basis point tax headwind. The pattern of earnings landing at or above the mark regardless of what the operating line did has broken.

Year-over-Year Comparison

Sequential Comparison

Read down the three year-over-year change rows and the quarter resolves into one sentence. Revenue growth has accelerated in each of the last two quarters, while the year-over-year change in the operating expense ratio and in the EBITDA margin has moved the wrong way in each of the last three. Those two trends are not independent. The revenue acceleration is coming from recycling commodity and from volume at newly commissioned sustainability plants, both of which carry lower margins than the collection-and-disposal business they dilute, and the surcharge line adds revenue at close to no margin at all. WM is growing its top line into a mix that pushes its margin down.

Quality of Beat/Miss

Segment Performance

The segment adjusted EBITDA lines sum to the reported total exactly, so the mix reading below is not an approximation. Every segment grew revenue and every segment grew adjusted EBITDA. Two expanded margin and two contracted it, and the two that contracted are the two that carry 84% of the company's revenue and 90% of its segment-level adjusted EBITDA.

Sequential Segment Detail

The sequential table exposes what the year-over-year table conceals. Three of the four operating segments gave up margin sequentially, and two of them gave up absolute EBITDA dollars on higher revenue. Healthcare Solutions carried the entire sequential improvement in company margin on its own, plus a $16 million reduction in the corporate drag. Strip Healthcare out and the business went backwards quarter on quarter.

Collection and Disposal

Revenue grew 4.8% to $5,579 million on yield of 3.4% and workday-adjusted volume of negative 0.5%. Adjusted EBITDA grew 2.9%, so margin fell 70 basis points to 38.3%. That is the first year-over-year decline this segment has posted in our coverage: plus 110 basis points in the first quarter, flat in the second, minus 70 now. The trajectory is a 180 basis point swing across three quarters in the business that is supposed to be structurally compounding its margin.

The composition is mixed in a way that matters. Core price of 5.8% ticked up from 5.7% and sits at the top of the 5.4% to 5.8% full-year plan, while yield of 3.4% ticked down from 3.6%. Management was asked directly about that widening gap and attributed it to disposal mix: a few planned site closures and higher-priced but not higher-profit volume shifting on the West Coast. Within collection, the price-to-yield conversion was described as running in the mid-sixties percent, which is normal. So the pricing machine is intact and the dilution is on the post-collection side.

"Core price again was strong at 5.8% for the quarter. Despite a 70-basis-point headwind from higher fuel costs, total company operating expenses remained below 60% of revenue, demonstrating the increasingly important role of technology combined with process improvements is playing in sustaining our performance and helping us to structurally lower our cost to serve." — John Morris, President and incoming Chief Executive Officer

The quoted 70 basis point fuel headwind is to operating expenses, against the 40 basis point figure the release gives for the EBITDA margin effect. Both are correct and they measure different things. Volume by line of business: commercial negative 1.3% on prior national-account broker losses and softer small-business formation, industrial flat to slightly positive, residential negative 2.6% against negative 3.5% for the nine months as the intentional shedding runs off, transfer positive 1.8%. Construction and demolition volume is down about 4.5% year to date against housing starts management put at "a million 2 and change." Commercial churn improved 30 basis points to 9.3%, which is the single best piece of evidence that the pricing is not buying the volume decline.

Assessment: The pricing engine is working and the volume book is behaving roughly as guided. The margin is not, and the reason is only partly external. Of the 70 basis point decline, 41 basis points is the $23 million risk-management charge sitting inside the segment and the balance is fuel and disposal mix. Back out the risk charge entirely and margin was still down about 30 basis points. For a business whose whole investment case is a structurally widening price-to-cost spread, a quarter in which spread contributed 40 basis points to company margin while the segment's own margin fell 70 is a quarter that needs the next one to reverse it.

Recycling Processing and Sales

Revenue grew 18.5% to $441 million and adjusted EBITDA grew 40.0% to $91 million, lifting margin 320 basis points to 20.6%. Both the volume and the price moved the right way: the automated network built out over the last three years is processing more material, and the blended single-stream commodity price realised roughly $82 a ton against roughly $68 a year earlier. Internalization of waste reached 72.1% against 71.9%, and management attributed part of that to recycling volumes being routed into WM's own plants rather than to third parties.

"Recycling Processing & Sales segment operating EBITDA increased 40% to $91 million in the third quarter. That strong growth reflects the benefits of our investments in our automated network as well as year-over-year improvements on our blended average commodity price." — John Morris, President and incoming Chief Executive Officer

Sequentially the picture is less flattering. Revenue rose 9.4% while adjusted EBITDA fell 1.1% and margin gave up 220 basis points from 22.8%. The commodity was higher in the third quarter than the second, so the sequential margin decline is a volume-mix and cost outcome rather than a price one.

Assessment: This is the segment where the capital programme has most clearly converted, and the year-over-year numbers deserve the credit they are getting. The caution is that about $12 a ton of the realised price sits above the planning assumption, worth roughly $32 million of annualised EBITDA on the company's own stated sensitivity of $27 million per $10 a ton. That is a tailwind the 2027 guide will not be able to assume, and the sequential margin decline on rising revenue suggests the operating leverage here is thinner than the year-over-year comparison implies.

Renewable Energy

Revenue grew 45.2% to $167 million and adjusted EBITDA grew 35.4% to $65 million, so margin contracted 280 basis points to 38.9%. The segment added an eighteenth renewable natural gas facility during the quarter, in New York, with one more due in the fourth quarter and the final one in early first quarter 2027. More than 90% of expected 2026 production and about 40% of 2027 production is already contracted. Realised pricing moved in two directions: renewable fuel credits fell to $2.32 from $2.56, while natural gas rose to $2.56 per MMBtu from $2.46 and electricity to about $78 per megawatt hour from about $73.

The sequential series is the story here, and it is now two quarters long. Adjusted EBITDA has gone $72 million, $71 million, $65 million across the first three quarters of 2026 while revenue went $159 million, $157 million, $167 million. Segment margin has gone 45.3%, 45.2%, 38.9%. A business whose output is rising and whose earnings are falling is either absorbing start-up costs or selling into a worse market, and management named both.

"1, we sold more volume in the voluntary market in Q3. Which would be at a lower price per MMBtu. That is the first item. And the second is we did have some start up costs that flowed through the P and L. So it is 1 of the reasons why I always point you to looking at margins in this business and for the full year because we can have some lumpiness quarter to quarter." — David Reed, Executive Vice President and Chief Financial Officer

Management also confirmed that the production shortfall flagged at the second quarter, caused by pipeline interconnect and plant start-up issues, landed mostly in the third quarter, and that a sequential pickup should follow in the fourth. The full-year realised RNG price is tracking to about $27 per MMBtu against the $26 long-term framework.

Assessment: The request to judge this on full-year margins is fair and we accept it. What we will not accept is a third consecutive sequential decline. The segment has consumed the largest share of the sustainability capital programme and it is the one piece of the growth story with no pricing power of its own, since both renewable credits and natural gas are set elsewhere. Two built plants that could not reach a pipeline were a second-quarter disclosure; the first-quarter 2027 completion of the final facility ends the construction story and makes 2027 the first year in which this segment must be judged purely on operations.

Healthcare Solutions

This was the quarter's best segment by a distance. Revenue grew 3.7% to $651 million, the first year-over-year revenue growth since the Stericycle acquisition closed. Adjusted EBITDA grew 32.7% to $146 million and margin expanded 491 basis points to 22.4%. Segment SG&A reached 15.2% of revenue, a 190 basis point improvement, and core price reached 5.5%. Management presented both as year-end targets achieved a quarter early. The SG&A claim stands. The core price claim re-frames the goal: at the second quarter it was an exit rate above 5.5%, with the then-CEO putting it at 5.7%, so 5.5% is on the path rather than at the target. The synergy target is now expected around the middle of 2027, ahead of the original plan, and the underwritten case implied a 17% margin against the 22.4% just printed.

"We had 2 year-end targets for the business as we exit 2026. Core price at 5.5% and SG&A of between 15%-16% of revenue. We achieved both of those targets earlier than expected with third quarter core price coming in right at 5.5% and SG&A at 15.2% of revenue. This progress reinforces our confidence that we can bring the same price and cost-discipline to health care that has driven our success in solid waste." — John Morris, President and incoming Chief Executive Officer

Now the composition of the revenue inflection, which is the single most important disclosure in the release that management did not volunteer. The internal revenue growth schedule reports the Healthcare Solutions change from yield and volume combined, excluding energy surcharges, at $1 million, or 0.0% of the segment. Against reported revenue growth of $23 million, that means $22 million came from surcharges and other items. With disclosed core price at 5.5%, price alone on the $628 million prior-year base is worth roughly $34.5 million, so volume must be around negative $33.5 million, or approximately negative 5.3%. Management acknowledged a fuel tailwind in the business and declined to give a volume figure for a third consecutive quarter.

Assessment: The cost and pricing execution here is now beyond argument, and it is the most valuable thing happening at WM. The SG&A target hit a quarter early, core price at 5.5% on the way to a goal above it, a synergy date pulled forward, and 491 basis points of margin in a single year-over-year comparison is an integration that has turned. The qualification is precise: the revenue inflection that generated the headline is a fuel-surcharge event, not a volume event, and underlying volume is running down roughly 5%. Management framed the trend as improving in both medical waste and secure information destruction, and twice refused to say when it turns positive. Until it does, this segment is a margin story resting on a shrinking base, and a 22.4% margin on a book that loses 5% of its volume a year compounds to less than it appears.

Key KPIs

The Healthcare volume row is derived, not disclosed. The method is in the note below the segment discussion above: reported revenue growth, less the release's own yield-and-volume figure of $1 million, against a disclosed core price of 5.5%.

Guidance & Outlook

The affirmation is a three-legged statement and the legs are not the same length. Revenue to the high end and free cash flow to the high end are genuine upgrades within an unchanged range. Adjusted EBITDA "within the range" is the only one of the three that was not narrowed, and the range is $100 million wide. In a quarter where two of three guides move up and the third does not, the third is the one that is under pressure.

Two things then compound that. The first is that the full-year margin guide is simply gone. It was 30.8% to 31.0% in January, raised 20 basis points to 31.0% to 31.2% in July with an explicit quote about flexing cost and driving productivity, and it does not appear in the October affirmation at all. The second is that it could not have appeared, because at the guided revenue high end it no longer fits inside the EBITDA range.

Implied Q-over-Q ramp: fourth-quarter revenue of $6,718 million at the guided high end, up 6.4% year over year and down 1.9% sequentially, with adjusted EBITDA of $2,109 million to $2,209 million and margin of 31.4% to 32.9% against the 31.0% just printed. Management named four levers that would push results up the range: a sequential recovery in renewable energy as the third-quarter start-up shortfall annualises away, continued pricing strength in solid waste and healthcare, any improvement in special-waste volume, and incremental recycling commodity strength. None was quantified.

Street at: the full-year revenue consensus of roughly $26.39 billion sits at the guidance midpoint, below the high end management now guides to. The full-year adjusted EBITDA consensus of about $8.2 billion sits at the guided midpoint, which is the level the CFO's own fourth-quarter description does not reach. Consensus is therefore carrying a fourth quarter that requires year-over-year margin expansion in a quarter management has described as facing year-over-year margin pressure.

Guidance style: WM has beaten or met its original full-year adjusted EBITDA guidance in every year of the departing CEO's tenure except 2020. That record is the strongest argument for the midpoint and management invoked it directly on the call. It is also an argument about the range, not the midpoint: landing at $8,153 million is still inside the range and still extends the record.

Key Topics & Management Commentary

Overall Management Tone: Confident on the operating narrative and visibly more guarded on the fourth quarter than at either prior call this year. The prepared remarks were the most upbeat of the three, leading with the diversification argument that every segment grew earnings, but the first analyst question moved the discussion to fourth-quarter margin shaping and management spent the rest of the hour defending a range rather than a number. Where the second-quarter call produced a guidance bridge that reconciled to the dollar, this one answered the same class of question with a list of unquantified levers. The retiring chief executive's valedictory framing sat oddly against a quarter that missed on earnings, and the incoming chief executive's answers on volume carried a repeated refusal to commit to a turn date.

1. The chief executive transition, and what it does and does not change

The call opened with the retirement announcement rather than the results. The departing chief executive leaves in early January after ten years in the role, and the current president becomes chief executive at that point. The succession was described as the outcome of a deliberate board process, and the incoming chief executive has worked alongside the same leadership team for years.

"As most of you know, after concluding 10 years as CEO, I will be retiring in early January. At that time, John Morris will become WM's new CEO. John's promotion is the result of a thoughtful, deliberate succession planning process by our board of directors, and I have the utmost confidence that John is the right person to lead WM into its next chapter and build on the momentum that we have established." — Jim Fish, Chief Executive Officer

Asked directly whether strategic priorities change, the incoming chief executive named four that do not: returning cash to shareholders, a more aggressive core solid-waste acquisition programme now that Healthcare has turned, continued integration and cross-selling in Healthcare, and the technology and cost programme. He was explicit that no shift was coming.

"There is not going to be any big shifts in the way, I think, just because Jim's gonna retire here in a few months. We have all worked together for a long time and built this strategy collectively. So I feel like we have got a terrific path charted that we are gonna continue to pursue." — John Morris, President and incoming Chief Executive Officer

Assessment: This is as clean a succession as a large-cap transition gets: internal, long-signalled, and with the incoming executive already presenting the operating results. The consequential detail is one of timing rather than personnel. The 2027 guide will be set at the fourth-quarter call in late January or early February, by which point the new chief executive will have been in the seat for weeks. New chief executives setting their first annual guide have a structural incentive to set a bar they can clear. For a company whose multiple rests on a reliable earnings algorithm, the risk is not that the strategy changes but that the first guide is deliberately conservative and the market reads conservatism as deceleration.

2. The margin bridge, and why only half of it is external

The release gives a four-line bridge that reconciles exactly to the 10 basis point compression: Collection and Disposal price-to-cost spread plus 40, Healthcare operations plus 30, fuel minus 40, risk management minus 40. The first instinct is to treat both negatives as noise and credit the business with 70 basis points of underlying expansion. Last quarter we did exactly that with the wildfire comparison and the surcharge dilution, and it was correct then.

"These core business contributions were offset primarily by a couple of headwinds. 40 basis points from higher fuel cost and 40 basis points from increased risk management costs within our corporate and other segment. Even with those headwinds, the underlying performance of the business remains strong and demonstrated our ability to protect profitability while continuing to invest for long-term growth." — David Reed, Executive Vice President and Chief Financial Officer

Note the phrase "within our corporate and other segment." That framing is contradicted in the same call by the segment split management gave minutes later: $40 million of the risk increase in Corporate and Other and $23 million in Collection and Disposal. The risk cost is not confined to corporate.

Assessment: Accept the fuel 40 basis points as external. The surcharge programme recovers direct and third-party fuel cost, and the recovery lags by about a month, so a quarter containing an 80 cent per gallon spike mechanically under-recovers and the following quarter catches up. Do not accept the risk 40 basis points as purely corporate. A third of the dollar increase landed in the operating segment, which is where the investment case lives.

3. The risk-management charge, located and sized

The largest single new disclosure of the quarter came in answer to a question, not in the release. The year-over-year increase in risk cost was $63 million, split $40 million in Corporate and Other and $23 million in Collection and Disposal. Three causes were given: an adverse third-quarter actuarial adjustment, cost-estimate increases on a few large loss claims, and a difficult comparison against a prior-year insurance recovery. Management was careful to separate the charge from safety performance, noting that recordable injury and accident rates improved across the business including Healthcare.

"...for the company in general, it is about a $63 million increase year over year for Q3. The higher risk costs were attributed to 3 items. The first of which is we had a negative impact associated with our third quarter actuarial adjustment. It is always a little bit of a wild card, but I would point out that you know, this follows 6 consecutive quarters of positive variances against our actuarial report." — David Reed, Executive Vice President and Chief Financial Officer

The six-consecutive-favourable-quarters point is the right defence and it is a real one. An actuarial reserve that has run favourable for six quarters and adverse for one is a reserve being marked, not a business deteriorating. The $23 million that landed in the operating segment is 41 basis points of Collection and Disposal margin, so adding it back takes the segment's year-over-year decline from 70 basis points to about 30.

Assessment: Credit the disclosure. Management quantified it, split it by segment and named its causes without being pushed twice, which is more than most companies offer on a one-off cost line. Two cautions remain. The company would not say the item does not recur, only that it does not expect "an outsized negative impact as we carry forward," which is a hedge rather than a reversal. And the six-favourable-quarters framing cuts both ways: if six quarters of favourable development flattered prior margins, the structural cost base was never quite as good as it printed.

4. The MSW series keeps eroding, and nobody asked about it

The landfill-scarcity argument is the reason a waste company earns a premium multiple. Its measurable expression is municipal solid waste pricing, because a scarce disposal asset should be able to price above inflation regardless of volume. That series has now decelerated for three consecutive quarters and the volume beneath it has turned negative.

MSW yield has roughly halved in three quarters. The partial offset is that transfer yield of 2.7% came with positive 1.8% volume, the only positive volume line in the disposal book, and that management has a specific plan to price post-collection assets harder going into 2027.

"We think that we have an opportunity if you look at where our post collection assets are and how critical an advantage they are within the network. And, also, we are experiencing some increased landfill operating costs, and we expect those to persist. A great example of that is in California where there is new legislation that will require enhanced monitoring and some other things that will flow. And we know that we can pass along these costs through pricing and leverage that. So as we look to 2027 and beyond, we are going to look to continue to enhance our landfill and transfer station pricing." — David Reed, Executive Vice President and Chief Financial Officer

Assessment: We flagged this series at the second quarter when MSW yield fell from 6.9% to 5.2% and it was characterised on that call as having "moderated a little bit" and not asked about. It was not asked about this quarter either. Three quarters of deceleration from 8.1% to 4.2%, with volume now negative, is the specific evidence on which the structural pricing pillar rests, and it is running the wrong way while the stock still carries a scarcity premium. The stated intention to price landfill and transfer harder in 2027 is the right response and it is also an admission that the current level is not where management wants it. This moves our first bull pillar off ON TRACK.

5. Volume: the quarter improved, and the full-year assumption held

Collection and Disposal volume was negative 0.4% reported and negative 0.5% workday adjusted, an improvement on the negative 1.3% nine-month rate. The full-year assumption is about negative 1%, or negative 0.5% excluding prior-year wildfire cleanup volumes, which reaffirms the July framing of a decline "approaching 1%" rather than cutting it. The only revision this year came in July, away from the January range of positive 0.2% to positive 0.6%. The figure of about negative 0.8% that we carried from July was a hedged figure from the July Q&A, not the prepared guide.

"Overall, our core price and yield are tracking to the high end of our guidance with volume still expected to be about -1% for the year or negative 50 basis points when excluding wildfire cleanup volumes from the prior year." — David Reed, Executive Vice President and Chief Financial Officer

Underneath, the composition improved where management said it would. Residential at negative 2.6% is better than the negative 3.5% nine-month rate, and management pointed out that residential revenue is up about $40 million despite the volume loss, which is the intentional-shedding trade working. Industrial roll-off was flat to slightly positive, which management reads as a construction indicator holding up better than construction and demolition landfill volume, down about 4.5% year to date. Commercial at negative 1.3% is slightly worse than the second quarter, on the national-account broker losses that lap around the end of the first quarter of 2027 and softer small-business formation.

The forward-looking item is special waste. Management reported that 16 operating areas describe strong pipelines that have not yet converted, and attributed the delay to a wait-and-see posture rather than an absence of work.

"...we spend a week every quarter with our areas, and 16 of them pretty much across the board are saying, their special waste pipelines are very strong. It is just some of these special waste pipelines have not yet hit, so it is not a question of if. It is more of a question of when." — Tara Hemmer, Executive Vice President and Chief Operating Officer

Assessment: The quarterly volume number improved and the mix improved with it, which is the first genuinely encouraging volume datapoint of the year. The full-year assumption was held at about negative 1%, which means the better quarter was already inside the July framing rather than upside to it. The annual figure has recovered none of the gap to the January plan. The commercial broker lap at the end of the first quarter of 2027 is a real and dateable tailwind. The special-waste pipeline is not dateable and has been described as imminent for two quarters.

6. The margin guide was dropped without a word

In July management raised the full-year adjusted EBITDA margin guide by 20 basis points to a range of 31.0% to 31.2% and gave a quote about flexing cost and driving productivity to explain it. Our assessment at the time was that the raise contained no incremental profit, because holding the EBITDA midpoint while cutting the revenue midpoint by $150 million lifts the ratio by about 18 basis points on its own, and that an investor who modelled to the margin guide rather than the EBITDA guide would double-count the same event.

The October release affirms revenue, adjusted EBITDA and free cash flow. It does not mention the margin guide. Nor could it: at the guided revenue high end of $26,475 million, the EBITDA range ceiling of $8,250 million produces a 31.16% margin and the $8,200 million midpoint produces 30.97%, below the guide's own 31.0% floor. Guiding revenue up while leaving EBITDA flat mechanically guides margin down.

Assessment: The July margin raise has now completed its full life cycle in two quarters. It was created by a revenue cut, it was presented as operating progress, and it has been retired in silence by a revenue increase. No analyst asked about it. For our purposes it validates the second-quarter judgement that the EBITDA guide was the only commitment that mattered, and it is a reminder that a ratio guide and a dollar guide can be moved against each other without either being broken.

7. Healthcare Solutions: the integration turned, and the volume is still withheld

The segment SG&A target was achieved a quarter early at 15.2% of revenue, and core price reached 5.5%, which management described as a second target hit early although the July goal was an exit above 5.5%. Adjusted EBITDA grew 32.7% and margin expanded 491 basis points. The synergy target moved forward to around the middle of 2027, and the underwritten case implied a 17% margin against the 22.4% delivered. Management declined to set a new SG&A target, saying only that it would be better than 15.2% and that a number would come with 2027 guidance. Pressed on whether the business could eventually reach the corporate level of 9% to 10%, the answer named customer-service intensity in hospitals as the one structural difference and conceded the field business probably could.

"And I think just from an investment thesis, you know, the synergies that we underwrote with the deal were going to get us to 17% and we are already past that. So I think from that goalpost that we are we look really well. But to John's point, we see further room to go." — David Reed, Executive Vice President and Chief Financial Officer

On volume, the posture is unchanged from the prior two quarters: trends improving in both medical waste and secure information destruction, secure destruction moving faster, no commitment on when either turns positive. Management described a long tail on customer losses already incurred and pointed to hospital same-store growth as the eventual driver.

"...not ready to put a stake in the ground on positive volume for the medical waste side of the house or the secure document destruction, but the trends are improving. So as we move into 2027, we know that we are gonna continue to see benefits there. When it gets to positive is still a little bit yet to be determined, but we are really happy with the progress the team's making." — John Morris, President and incoming Chief Executive Officer

Assessment: This pillar is now the strongest in the thesis on execution and the weakest on durability. Hitting the SG&A target a quarter early, lifting core price 100 basis points in a quarter and pulling a synergy date forward is unambiguous delivery, and the margin is 540 basis points past what the deal underwrote. But a cost programme on a book losing roughly 5% of its volume annually has a finite runway, and the revenue inflection that generated this quarter's headline came from the fuel surcharge rather than from the business. The honest summary is that WM bought a badly-run asset and has fixed the running of it, and has not yet demonstrated that it bought growth.

8. Free cash flow and the capital return: the harvest year delivered

Nine-month free cash flow of $3,009 million is up 42.3% and represents 50% conversion of adjusted operating EBITDA, a level the chief financial officer called "almost aspirational." Operating cash flow is up 12.0% and total capital spending is down 17.2%, with sustainability capital down 55.5% as the construction programme completes. The company has returned $2,724 million, or 90.5% of free cash flow, through $1,583 million of buyback and $1,141 million of dividends. Leverage finished at 2.92x, down from 2.96x after the second quarter's uptick, delivering on the second-quarter commitment.

"A lot of that was expected. We have talked a lot about this year being harvesting. So the strong earnings growth the lower capital spending that we have been alluding to for a number of quarters now. Are playing out as we anticipated. I will say a couple of other areas that have been pleasant surprises. You know, cash taxes was a bit favorable relative to what we thought we were gonna have for this year. And then we have had a nice improvement, a nice sustained improvement in working capital, particularly around accounts payable." — David Reed, Executive Vice President and Chief Financial Officer

Two qualifications sit inside the upgrade to the high end. The outperformance was attributed to cash taxes and to accounts-payable-driven working capital, neither of which is an earnings event, and fourth-quarter capital spending was guided sequentially higher, with full-year total capital spending "more towards the higher end" at about $2.75 billion including the raised sustainability line. Quarterly free cash flow was $985 million against $1,104 million in the second quarter.

Assessment: This is the quarter's cleanest win and the one that most improves the valuation case. Forty-two percent free cash flow growth with leverage falling and 90% of the harvest returned is exactly what was promised in January. The caution we raised in July has partially resolved the right way: the guide was raised to the high end rather than the payables position reversing. But a vendor-payment-timing benefit is a one-time pull-forward by construction, and a 50% conversion rate built partly on favourable cash taxes and partly on a capital trough is not the 2027 run rate. The underlying question for the new chief executive's first guide is what conversion looks like once capital returns to the 10% to 10.5% of revenue framework management reaffirmed.

9. Acquisitions: a hole in the third quarter and a back-loaded pipeline

Nine-month acquisition consideration of $239 million already exceeds the original $100 million to $200 million annual tuck-in range. The quarter itself did almost nothing: $4 million of total consideration and $3 million of gross annualised revenue acquired. About $140 million is expected to close in the fourth quarter and a $250 million transaction has been signed for early 2027.

"We have completed $239 million of deals through the first 9 months of the year and expect to close another $140 million in the fourth quarter. Also signed a $250 million transaction that we expect to close early next year. And our pipeline remains robust, supporting continued acquisition activity into 2027." — John Morris, President and incoming Chief Executive Officer

The deals were characterised as core solid waste with internalization and routing synergies rather than adjacent businesses, and higher interest rates were framed as a positive on the seller side, since close to 90% of WM's own interest-rate exposure is fixed while private operators facing a recapitalisation see high rates. Management also said it would be interested in core solid-waste assets from any larger-player divestiture, in any geography, and in hazardous or industrial assets it could wrap services around.

Assessment: The programme is real and the strategic logic is sound, with the rate environment genuinely asymmetric in WM's favour. Two notes on the shape. First, the commitment is now substantially larger than the original plan without a refreshed annual figure, which is the second consecutive quarter in which this line exceeded guidance with no new guidance attached. Second, $4 million in a quarter against $390 million of announced forward activity means the 2026 acquisition contribution lands almost entirely in the fourth quarter and 2027, so modelling it as a smooth annual contribution will be wrong in both directions.

10. Landfill cost inflation, and the pricing answer to it

Newly passed California legislation will require enhanced landfill monitoring, and management expects landfill operating costs, particularly leachate handling, to rise and persist. The response offered was pricing rather than mitigation, grounded in the next-best-alternative analysis WM uses to price disposal. Management does not expect the California requirements to become widespread but is tracking the question, and stressed that the cost is industry-wide rather than company-specific.

"We also know how to pass those costs along to our customers through price increases and recognizing the strategic nature of our assets we have always used a next best alternative analysis on how to price, and that is part of an evolution of our pricing analytics. And we are gonna use that as we navigate increased operating expenses at our landfills. And by the way, it is not just us. This is an industry wide issue, and so everyone is gonna be faced with some of these same issues across the board." — Tara Hemmer, Executive Vice President and Chief Operating Officer

On emerging contaminants, the position on treatment of landfill operators as passive receivers remains unresolved, and management framed the outcome as both a potential cost headwind recoverable through price and a potential opportunity on the remediation side.

Assessment: This is the thesis working in the direction it is supposed to. Cost inflation at a scarce asset with an industry-wide driver is the textbook case for pricing power, and WM is the operator best placed to exercise it. The tension is with the section above: the company is proposing to price landfill harder into 2027 precisely while MSW yield has halved over three quarters. Both can be true, and the resolution matters. If landfill pricing reaccelerates in 2027 on a cost pass-through, the scarcity pillar is intact and this quarter's MSW series was a mix artifact. If it does not, the pass-through assumption is doing work the market is already paying for.

11. Technology and labour: the 50 to 100 basis point framework

Management reframed the technology programme from a project list into a standing margin framework. The specific tools named were overage detection on trucks, daily routing optimisation on the industrial line using real-time traffic, safety instrumentation, robotics upgrades in processing plants, and predictive pricing analytics that management credits with the syndication of price across the business and increasingly in Healthcare.

"And we are also looking at where we might have opportunities to leverage AI in some unique applications really into helping our dispatchers. Way I would frame our technology journey is this is something that is been a part of our fabric for several years now, and it is going to be what we lean into to continue to expand margins in that 50- to 100-basis-point range consistently over time." — Tara Hemmer, Executive Vice President and Chief Operating Officer

On labour, the long-term framing is structural reduction of dependence rather than cost control, with remote heavy-equipment pilots running with a construction-equipment partner at a hazardous landfill and an Arizona facility. The stated rationale was both cost and access to a different labour pool, against an expected long-term shortage.

Assessment: Quantifying the technology programme as a 50 to 100 basis point annual margin framework is useful and we will hold management to it, because this quarter delivered negative 10. A framework stated in the same quarter the metric it governs goes backwards invites the obvious question, and the answer management would give is that fuel and risk masked it. That is probably right. It is also what a framework is for: 2027 is the year in which the 50 to 100 basis points has to appear in the printed margin rather than in the bridge.

12. The guidance asymmetry, stated plainly

Three guides, three different treatments. Revenue to the high end. Free cash flow to the high end. Adjusted EBITDA "within the range," with the margin guide withdrawn. Management's own enumeration of what moves EBITDA up the range was a list of four conditionals, none quantified: renewable energy's sequential recovery, pricing strength, special-waste volume, and recycling commodity.

"It is whether it is, you know, improvement in volumes or strength in our pricing or recycling commodity prices, those will be the things that would move us up the range." — David Reed, Executive Vice President and Chief Financial Officer

Assessment: The asymmetry is the quarter's signal and the market read it correctly. Revenue and cash are being delivered above plan and earnings are being delivered within a range whose bottom is where the chief financial officer's own fourth-quarter arithmetic lands. Of the four levers named, three are outside management's control and one, the renewable energy recovery, is the annualisation of a problem rather than an improvement. The company that has beaten its original EBITDA guide every year but one in a decade is now steering by range width rather than by midpoint.

Analyst Q&A Highlights

Fourth-quarter margin shaping, and whether the guide lands low

The first question of the call went straight to the issue that defined the session, and it named the risk explicitly: a $100 million-wide EBITDA range, a typical sequential margin step-down into the fourth quarter, and the possibility of shading towards the low end. The answer disputed the sequential premise and conceded the year-over-year one.

Q: "I was hoping for maybe a little more color just on the Q4 EBITDA shaping. I mean, the range is still, call it, a $100 million at the EBITDA line. I mean, we typically see a slight step down in margin into Q4. Is that what we should expect? And would we maybe be shading towards the lower end on EBITDA for Q4?"
— Tyler Brown, Raymond James

A: "And note that similar to last year, we did have improving margins sequentially throughout the year. And we expect our best performance from a margin perspective in Q4. But having said that, if you think about the margin impact of fuel this year, which we are assuming is about a 40 basis point impact, our year over year margin comparison will likely be a bit lower than the fourth quarter of 2025, all else equal."
— David Reed, Executive Vice President and Chief Financial Officer

Assessment: The correction on sequential direction is accurate and useful: the fourth quarter should be the year's best margin quarter, not a step down. The concession is the material half. Saying the year-over-year comparison will be "a bit lower" than a restated 31.84% is saying the fourth quarter prints somewhere near 31.4%, which puts the full year within a few million dollars of the bottom of the range. An opening answer that concedes the low end of the earnings guide is not how a company that is tracking to its midpoint answers this question.

The implied full-year arithmetic, challenged live on the call

Later in the session a different line of questioning did the arithmetic out loud and asked whether it was wrong. This was the most consequential exchange of the call and it is the reason the stock finished lower than its after-hours level.

Q: "If I plug that in and just take the revenue number, then that actually puts me just below the low end of the EBITDA range. So there may be something wrong we are doing here, but you know, I think that would suggest that you are heading towards the lower end of the guide for the year. So anything that we are getting wrong?"
— Noah Kaye, Oppenheimer

A: "Well, that is just on the. I am just making the assumption on the fuel, the 40 basis point impact of fuel, but I did highlight some of the, you know, some of the items that depending on how they play out in the quarter will push us up higher in that range as well. That is just fuel isolated."
— David Reed, Executive Vice President and Chief Financial Officer

Assessment: The arithmetic was not disputed, and that is the answer. Management had the opportunity to say the calculation was wrong and instead said the fuel assumption was being taken in isolation. Our own version of the same calculation lands at $8,153 million, three million dollars above the floor, so the questioner's "just below the low end" is directionally right and marginally pessimistic. What makes the exchange damaging is not the number but the structure of the rebuttal: four unquantified upside levers against one quantified headwind. Investors can model the headwind.

The risk-management charge: what it was, and where it sat

A follow-up pressed on whether the risk cost was in corporate, whether it was accident or premium related, and whether it persists into the fourth quarter and 2027. The response separated the charge from safety performance, then quantified and split it, which is more than the release had done.

Q: "I think you mentioned that risk was a sizable headwind. So, 1, to be clear, was that in corporate? And, 2, was it accident or insurance premium related, or what exactly is that? And then is that something that lingers into Q4 and into 2027, or how should we think about that?"
— Tyler Brown, Raymond James

A: "I would tell you first and foremost, it is not related to our safety performance. It has more to do with, sort of an out of period adjustment that happened in Q3. But if you look at our safety statistics and performance. That is not what is driving it. In fact, across the broader business, including our health care business, we are seeing a nice improvement in our recordable injury and our accident rate."
— John Morris, President and incoming Chief Executive Officer

Assessment: The quality of this answer is high. An out-of-period actuarial adjustment following six consecutive favourable quarters is a mark-to-model event, not an operating deterioration, and the improving injury and accident rates are the right corroboration. The part of the question that was not answered is the part that was asked twice: whether it lingers. The furthest management went was that it does not expect "an outsized negative impact as we carry forward," which rules out a repeat of this size without ruling out recurrence. And the segment split given moments later put $23 million of it inside the operating business, which the CFO's prepared remarks had attributed to corporate.

Healthcare's revenue growth, decomposed from the release

The sharpest piece of analysis in the session came from a questioner reading the internal revenue growth schedule against the segment revenue line and noticing they do not tell the same story. The exchange established the single most important qualification on the quarter's best headline.

Q: "But I think health care revenue was up maybe 4%. If I look at core price and volume, it only contributed maybe $1 million of revenue growth. And I think, John, you said that core pricing was up 5. So were volumes down about 5? It seems that maybe most of that 4% was from fuel surcharges. But I guess regardless, it seems like good SG&A, management and the core pricing is what is driving the EBITDA there."
— Tyler Brown, Raymond James

A: "Some of the of the big pieces of that, we are really proud about where core prices at 5.5 percent. We said a handful of quarters ago, I think I said at this point, that will approximate what we do with the solid waste business. Had targeted to be at 5.5 at the end of the year. We are there at the end of Q3. SG&A, we said 15% to 16% at the end of the year. We are closing on 15% at the end of Q3, so really good story there."
— John Morris, President and incoming Chief Executive Officer

Assessment: The decomposition was not contested, including the fuel-surcharge point. Management gave no volume figure of its own, so the questioner's roughly 5% decline stands unrebutted rather than confirmed. That matters because the segment's first year-over-year revenue growth since the acquisition is the headline achievement of the quarter, and it rests on a surcharge line. The answer did not dispute the mechanism and once again declined to date the volume turn. This is a cost and pricing success on a shrinking base, correctly described by the questioner and not disputed by management.

Why the gap between core price and realised yield widened

A question on the pricing mechanics noted that core price of 5.8% against Collection and Disposal yield of 3.4% is a wider spread than the recent range and asked what mix was driving it and what level is sustainable. The answer located the dilution precisely on the disposal side.

Q: "I think core price was strong at 5.8% this quarter with yield of 3.4% in collection disposal. I think that spread is just a little higher than the recent range, and it ticked up sequentially. What sort of the mix impacts are impacting that? And what do you view as more of a sustainable level of that core price yield spread going forward?"
— Adam Bubes, Goldman Sachs

A: "Yeah. I think we have said we have generally been, like, low sixties to 70%. We have ticked up a little bit higher from time to time. To your point, if you break it up and you look at collection, it was somewhere in the neighborhood of the mid sixties. Which is which is about the norm. What is been a little bit more pressured has been on the disposal side. What I would tell you is not to get into the weeds, but where we have looked at some of the volume mix with a few small deals that we closed, which we had planned to close, thinking ADS. There were a few of the sites that we closed in the quarter. And then some volume shifts out on the West Coast where it tends to be higher priced volume, does not necessarily mean higher profit volume, that is where I see a little bit of the pressure on the disposal side of the equation."
— John Morris, President and incoming Chief Executive Officer

Assessment: A specific and credible answer. Planned site closures and a West Coast volume shift from higher-priced but not higher-margin tonnage genuinely explain a yield conversion rate that fell while core price rose, and the collection conversion running in the mid-sixties confirms the collection pricing machine is unchanged. It also independently corroborates the MSW reading: the pressure is on the disposal side, which is exactly where the scarcity premium is supposed to live. The answer reframes a pricing question as a mix question without resolving whether the mix effect is transient.

Renewable Energy's sequential margin decline

A question observed that the renewable energy margin weakened sequentially and asked whether the cause was start-up and lower revenue or dilution from the newly commissioned facility, and what the right forward range is. The answer named two causes and asked for a full-year lens.

Q: "EBITDA margin just a bit weaker sequentially quarter on quarter. Was that just driven by, I guess, some of the sort of start up and slightly lower revenue you had flagged? Or was it just contribution from the New York facility that was brought online diluting overall margin? And how should we think about sort of the right range for that business going forward?"
— William Grippin, Barclays

A: "1, we sold more volume in the voluntary market in Q3. Which would be at a lower price per MMBtu. That is the first item. And the second is we did have some start up costs that flowed through the P and L. So it is 1 of the reasons why I always point you to looking at margins in this business and for the full year because we can have some lumpiness quarter to quarter."
— David Reed, Executive Vice President and Chief Financial Officer

Assessment: Both causes are plausible and neither was quantified, which leaves the investor unable to separate the transient from the structural. Voluntary-market mix is a pricing decision and start-up cost is a timing item, so neither should persist. The reason to keep watching is that this is the second consecutive quarter of declining absolute segment EBITDA on rising revenue, and the request to judge on full-year margins becomes less reasonable each time the sequential figure falls. The final facility completes in the first quarter of 2027, after which there will be no start-up cost left to attribute.

What drove free cash flow to the high end

A question asked directly what produced the free-cash-flow upgrade, whether it was timing, and whether it affects next year. The answer was unusually forthcoming about which parts were planned and which were not.

Q: "So I know you are saying you are now going to be at the high end of free cash flow guide, and, you know, you have not been specific around where in the guide you land on EBITDA. So just curious what is driving that higher free cash flow? Is it timing? And kind of any thoughts or whether that impacts next year?"
— Faiza Alwy, Deutsche Bank

A: "A lot of that was expected. We have talked a lot about this year being harvesting. So the strong earnings growth the lower capital spending that we have been alluding to for a number of quarters now are playing out as we anticipated. I will say a couple of other areas that have been pleasant surprises. You know, cash taxes was a bit favorable relative to what we thought we were gonna have for this year. And then we have had a nice improvement, a nice sustained improvement in working capital, particularly around accounts payable. And that is been driven by some of our active strategies and vendor management."
— David Reed, Executive Vice President and Chief Financial Officer

Assessment: The question embedded the asymmetry we regard as the quarter's signal, noting the free-cash-flow upgrade against the absence of specificity on EBITDA, and the answer did not address that contrast. On the substance it is candid: the planned component is earnings growth and the capital trough, and the two "pleasant surprises" are cash taxes and vendor payment timing. Both are below the earnings line and neither recurs by construction. The fourth-quarter capital step-up towards the higher end of the range, flagged in the same answer, is the first visible edge of the reversal.

Strategic continuity under the incoming chief executive

With the transition announced minutes earlier, a question asked what the incoming chief executive's priorities are and whether anything changes. The answer listed four continuities and explicitly ruled out a shift.

Q: "As you step into the CEO role, how should we think about your strategic focus, priorities. I know you have talked about potentially higher level of solid waste M and A. But curious if there is other, you know, areas of investments that you are thinking about, just kind of what your priorities are. And if anything changes."
— Faiza Alwy, Deutsche Bank

A: "We do think now that we have feel like we have turned the corner, if you will, on health care we have got the ability to be a little more aggressive in terms of what we do on the core solid waste side, and we see that as a strategic priority. As referenced in my prepared remarks, what we have done through the year to date, what we expect to close in Q4, we have already got teed up for the first quarter. Suggest that we have got good runway. And listen, that is a core competency of the organization is to bring in those core solid waste businesses and tuck those in."
— John Morris, President and incoming Chief Executive Officer

Assessment: Continuity is the right answer and the credible one, given a decade of shared strategy-setting and the fact that the incoming chief executive delivered the operating remarks on this call. The one substantive change disclosed is a deliberate step-up in core solid-waste acquisitions, which the $390 million of announced forward activity already evidences and which is funded by the same harvest that is feeding the buyback. The item not on the table is the one that matters most: the first annual guide under new leadership, due at the fourth-quarter call.

What They're NOT Saying

1. The full-year adjusted EBITDA margin guide: raised 20 basis points to 31.0% to 31.2% in July with a supporting quote, and absent from the October release entirely. No analyst asked where it went. It could not have been restated, because at the guided revenue high end the EBITDA midpoint produces a 30.97% margin, below the guide's own floor.
2. Where in the EBITDA range the year lands: revenue and free cash flow were both guided to the high end, and EBITDA was left "within the range." Asked twice, management described the fourth quarter in terms that reach the bottom of the range and listed four unquantified levers that could lift it.
3. Healthcare Solutions volume: withheld for a third consecutive quarter. The release discloses the segment's combined yield-and-volume contribution at $1 million, which with a disclosed 5.5% core price implies volume down roughly 5%. Management twice refused to say when it turns positive, saying first "not putting a stake in the ground" and later "not ready to put a stake in the ground."
4. Whether the risk-management charge recurs: the furthest management went was that it does not expect "an outsized negative impact as we carry forward." That rules out a repeat of this magnitude. It does not rule out recurrence, and the question was asked explicitly about the fourth quarter and 2027.
5. The MSW deceleration: yield has gone 8.1%, 6.9%, 5.2%, 4.2% over four quarters and volume has turned negative. It was not raised in the prepared remarks and not raised in the Q&A, for the second consecutive quarter. The disposal-side pressure surfaced only as an answer to a question about the core-price-to-yield spread.
6. A refreshed acquisition figure: nine-month consideration of $239 million already exceeds the original $100 million to $200 million annual range, and $390 million of further activity is announced for the fourth quarter and early 2027. No updated annual or forward number was given, for the second consecutive quarter.
7. The next Healthcare SG&A target: the 15% to 16% year-end goal was achieved a quarter early at 15.2%, and the replacement target is "better than 15.2%" with a number deferred to 2027 guidance. Pressed on whether the business can reach the corporate 9% to 10% level, management conceded the field business probably could and named hospital service intensity as the one structural obstacle.
8. The 2027 margin algorithm: asked to frame it conceptually, the chief financial officer cited low visibility, named renewable energy and recycling rollover as favourable, and said the outcome reduces to a call on macro volume. No range was offered, which is reasonable a quarter ahead of guidance and leaves the technology framework of 50 to 100 basis points as the only standing number.
9. The Healthcare cross-sell figure: asked for an update on the $32 million cited at the second quarter, management gave $38 million described as a restated prior full-year number. The two figures are not stated on a comparable basis and the trajectory of the $50 million target cannot be read from them.
10. The Arizona recycling facility fire: disclosed at the second quarter only as an offset to a better commodity outlook, with no cost, duration or insurance detail. It was not mentioned on this call, and the only Arizona reference was to a remote-equipment pilot facility.

Market Reaction

• Pre-print setup: the stock closed at $235.81 on 27 October, the print day, with the release landing after the close. It entered the print up 7.3% year to date against the S&P 500's 12.8%, up 10.3% over twelve months, and up 14.0% over the prior thirty days from $206.83 on 25 September. It sat 4.3% below its 52-week closing high of $246.51, inside a 52-week closing range of $196.77 to $246.51. The print-day session was itself weak, down 2.2% from $241.02, on a move that took the whole solid-waste group lower.
• After-hours move: reported between negative 2.3% and negative 3.5% across sources, with levels quoted at $229.57 and $230.13.
• Reaction session, 28 October: opened at $227.62, a 3.5% gap down, traded $224.64 to $230.30, and closed at $225.15, down 4.5% or $10.66.
• Volume: 3.7 million shares against a 2.3 million thirty-day average, 1.6 times normal.
• Peer reaction, same session: Republic Services down 1.0%, Waste Connections down 1.2%, GFL Environmental down 3.1%, S&P 500 up 0.3%.

The decline extended rather than faded. Every after-hours quote in circulation was between negative 2.3% and negative 3.5%, and the session closed at negative 4.5%. The incremental damage was therefore done during and after the call, not by the release. That sequencing matters for reading the cause. The earnings miss was fully visible at 4pm on 27 October; the fourth-quarter margin framing, the live arithmetic that put the full year at the bottom of the range, and the Healthcare volume decomposition were all call artifacts.

The move was company-specific but not entirely so. WM underperformed the S&P 500 by 4.8 points and its closest listed peer by 3.6 points, which is the signature of a stock reacting to its own print. The qualification is that the group had already given up 1.5% to 2.5% on the print day before the release, so the sector was soft going in. Measured from the 26 October close of $241.02, WM's two-session decline through the reaction day was 6.6%, of which roughly a third preceded the news.

Set against the setup, the reaction is proportionate rather than punitive. A stock that has run 14% in thirty days into a print carries no tolerance for an operational miss, and this was an operational miss: adjusted EBITDA 1.8% light, which is a wider shortfall than the 1.4% on earnings. The sell-off gave back a little over a third of the thirty-day run, about 37% of the gain from $206.83 to $235.81: at $225.15 the shares still sit 8.9% above the $206.83 of 25 September that the trailing-thirty-day statistic measures from. So the market trimmed the pre-print enthusiasm rather than reversing it, which is a modest de-rating rather than a reassessment of the franchise. Our own multiple progression says the same thing: enterprise value to guided earnings went from 14.4x in July to 13.8x here, the lowest of the coverage, and the de-rating happened because the price fell faster than the estimates did.

Street Perspective

Debate: whether the fourth quarter lands at the low end or the midpoint of the EBITDA guide

Bull view: The bull case on the Street holds that the fourth-quarter framing was deliberately conservative and that a company with a decade-long record of meeting or beating its original annual EBITDA guide does not steer towards the floor in October. Fuel is a recoverable timing item that catches up through the surcharge, the risk charge was an out-of-period mark, renewable energy recovers sequentially as the third-quarter start-up shortfall annualises, and recycling commodity is running $12 a ton above plan. On this reading the guidance language is the usual October caution and the midpoint holds.

Bear view: The bear camp contends that the arithmetic is the arithmetic. Nine-month EBITDA of $6,041 million plus a fourth quarter described as modestly down year over year in margin produces about $8,153 million, which is the bottom of the range. The margin guide has been withdrawn, revenue and cash were narrowed upward while earnings were not, and the only quantified input management gave was the headwind. Four unquantified upside levers do not offset one quantified drag.

Our take: The bears have the better of the arithmetic and the bulls have the better of the base rate. Our own calculation lands at $8,153 million on the chief financial officer's framing taken literally, and management declined to say that calculation was wrong when it was put to them. We model $8,180 million, in the lower half, because the recycling commodity tailwind and the renewable energy recovery are real but small relative to a $100 million range. The practical consequence is modest: the difference between the floor and the midpoint is 0.6% of full-year EBITDA. What is not modest is that the commitment the company chose to defend this quarter was its cash flow, not its earnings.

Debate: whether the Healthcare turnaround is a growth asset or a cost story on a shrinking base

Bull view: The bull case points to the cleanest execution in the portfolio. The SG&A target was achieved a full quarter early, core price reached 5.5%, the synergy date moved forward to mid-2027, margin expanded 491 basis points to 22.4% against the 17% the deal underwrote, and management conceded on the call that the field business could eventually approach corporate-level overhead ratios. On this view the market is still valuing a troubled acquisition while the asset has already become the group's best margin-expansion engine, with secular medical-waste growth still ahead of it.

Bear view: The bear camp notes that the reported revenue inflection, the quarter's headline, decomposes to $1 million from price and volume combined and roughly $22 million from fuel surcharges and other items. With core price at 5.5%, volume is running down around 5%, and management refused for a third quarter to say when it turns. A cost programme on a book losing 5% of its volume a year has a terminal date, and WM has yet to show it bought anything other than a fixable overhead problem.

Our take: Both are right about different time horizons, and the bear framing is the one that governs the next twelve months. Nearly everything management has committed to on this asset has been delivered on time or early, which earns the benefit of the doubt on the overhead runway. But the volume turn is the only thing that converts a margin story into a growth story, and it is the one item management will not date. We treat this pillar as on track and under a specific test: volume positive in at least one of the two Healthcare sub-businesses during 2027.

Debate: whether the core waste margin decline is external noise or the start of a trend

Bull view: Some sell-side desks argue the Collection and Disposal margin decline of 70 basis points is almost entirely fuel and an out-of-period insurance mark, that core price at 5.8% is at the top of plan with churn improving 30 basis points, and that the price-to-cost spread still contributed 40 basis points to company margin. On this reading the engine is intact and the quarter was a collision of two unrelated non-operating items.

Bear view: A growing bear view holds that the trend is the signal. The segment's year-over-year margin has gone plus 110 basis points, flat, minus 70 across three quarters, and the year-over-year change in the operating expense ratio has worsened in each of the three, from minus 180 basis points in the fourth quarter of 2025 to plus 90 now. Backing out the $23 million risk charge still leaves the segment down about 30 basis points. Meanwhile MSW yield has halved in three quarters and MSW volume has turned negative, which is the scarcity premium's own evidence eroding.

Our take: The bears are describing the right data and overstating the conclusion. Fuel genuinely reverses and the actuarial mark genuinely follows six favourable quarters, so a single quarter of segment margin decline is not a broken business. But three consecutive quarters of deterioration in the year-over-year change of the same two ratios is a trend by any reasonable definition, and the pattern is not explained by fuel alone. The MSW series is the part we weight most heavily, because landfill pricing is the mechanism the premium multiple is paying for and it is decelerating while management plans to accelerate it. That combination is what moves our first bull pillar to AT RISK rather than what moves the rating.

Model Update Needed

Our July marks are revised below for the guidance language, the segment mix and one quarter of evidence.

Valuation impact: At the $225.15 reaction close, WM trades at 27.7x our 2026 EPS base of $8.12 and 24.9x our 2027 base of $9.03, each inside our ranges above. Market capitalisation of roughly $90.0 billion plus $23.1 billion of net debt puts enterprise value near $113.1 billion, or 13.8x the midpoint of guided 2026 adjusted operating EBITDA. Free cash flow yield on the guide midpoint is 4.2% and the indicated dividend of about $3.78 yields 1.7%.

This is the first quarter in our coverage period in which every multiple improved. The comparable calculation produced 28.2x, 24.8x, 14.1x and 4.1% at the $230.31 close in April, and 29.0x, 25.8x, 14.4x and 4.0% at the $236.60 close in July. Enterprise value to guided EBITDA of 13.8x and a 4.2% free cash flow yield are both the best of the three. The reason is a reversal of the July dynamic: the stock fell 4.5% while our 2027 base of $9.03 sits only about 1.6% below the $9.18 July consensus, so the multiple came down faster than the estimates. The earlier multiples were struck on consensus and this quarter's on our own base, so the comparison is close rather than exact.

We hold the 26x multiple on 2027 earnings that has anchored our fair value since April. Nothing in this quarter argues for paying more, since the core segment's margin went backwards and the earnings guide is tracking its lower half, and nothing argues for paying less, since free cash flow is 42% ahead, leverage is falling again and the best-executing asset in the portfolio accelerated. On our $9.03 2027 base that gives approximately $235, about 4% above the reaction close, or roughly 6% total return with the dividend over twelve months. That is a wider cushion than the 1% we carried in July and a thinner one than an Outperform requires.

Thesis Scorecard Post-Earnings

Overall: Mixed, with the composition of the thesis shifting rather than its level. Two bull pillars moved to AT RISK and one bear point moved to MATERIALIZING, which is the worst pillar quarter of the coverage. Against that, the valuation bear point improved for the first time and the Healthcare pillar delivered unambiguously. The thesis is no stronger than it was in July and the price paid for it is better, which is the first time those two have moved in the investor's favour at the same time.
