[NSC] Norfolk Southern: Can the Q3 Fuel Tailwind Pull the Operating Ratio Back Below 65%

Norfolk Southern is one of the two Class I railroads in the eastern United States, operating roughly 19,100 route miles and charging customers across three commodity groups: merchandise, intermodal and coal[1]. The company has scheduled its earnings call for 2026-10-22 to report results for the third quarter of 2026, ending September 30, 2026[2]. The latest disclosed period, the second quarter of 2026, brought record revenue of $3.465 billion, up 11% year over year, with volume up 4% and fuel surcharges contributing six points of the growth; adjusted income from railway operations was $1.196 billion, up 5%, the adjusted operating ratio was 65.5%, 210 basis points worse than a year earlier with fuel alone accounting for 110 basis points, and adjusted diluted earnings per share were $3.52, up 7%[3]. On the second-quarter call, management raised full-year 2026 operating expense guidance from $8.2 billion to $8.4 billion to a range of $8.8 billion to $8.9 billion, attributing the entire increase to $400 million to $500 million of incremental fuel expense, kept capital expenditure at approximately $1.9 billion and the cost takeout target at no less than $150 million, and said the third-quarter operating ratio should beat the usual 0 to 50 basis point seasonal deterioration by up to 100 basis points, with fuel turning into a tailwind but a 4% wage increase effective in July offsetting part of it[4]. The Drillr earnings calendar, updated September 22, records third-quarter consensus of $3.557 in earnings per share and $3.439 billion in revenue[5], above the $3.34 and $3.33 billion that Zacks recorded on July 23, the results day, when second-quarter adjusted earnings per share of $3.52 beat the $3.23 consensus[6].

Three things deserve attention in the third-quarter report. The first is whether the adjusted operating ratio returns to 65.0% or below: of the second quarter's 65.5%, fuel contributed 110 basis points of headwind and inflation 190 basis points, the third quarter is the first in which lower year-over-year fuel prices and the 4% wage increase coincide, and the results release's split of the year-over-year change between fuel and inflation will directly test management's "up to 100 basis points better than seasonal" framing[3][4]. The second is whether domestic intermodal units keep growing at 8% or more year over year: second-quarter domestic units were 668.9 thousand, up 11%, which the 10-Q attributed to rising freight demand and constrained truck capacity, but the rate line for intermodal in the revenue bridge was only $3 million, so price has not yet followed volume, and the third-quarter comparison base is precisely the quarter in which customers began diverting freight after the merger announcement[7][8]. The third is whether the gains in merchandise and coal are durable: in the second quarter chemicals carloads rose 10%, the merchandise rate line was $52 million, export coal tonnage rose 25% and coal revenue per unit turned positive for the first time in two years, all of which coincided with the energy-market volatility triggered by the Iran conflict, and the third quarter will show whether they were a one-time pulse or a new running level[9][10][4].

Company Background and Business Structure

Norfolk Southern Corporation is headquartered in Atlanta, Georgia, traces its origins to 1827, and is a holding company engaged principally in rail transportation, with Norfolk Southern Railway as its major subsidiary and NSC as its New York Stock Exchange ticker[1]. At December 31, 2025, the company operated approximately 19,100 route miles across 22 states and the District of Columbia in the Southeast, East and Midwest, its heaviest-volume corridors run from New York to Chicago, Chicago to Macon and central Ohio to Norfolk, and it maintains 28,200 of the 35,000 miles of track on which it operates[11]. The network connects every major container port on the Atlantic coast as well as major Gulf and Great Lakes ports, and the company describes its intermodal network as the most extensive in the eastern United States[12]. It employed an average of 19,400 people in 2025 and 19,300 at year end, roughly 80% of them covered by collective bargaining agreements[13].

Two company-level events define the current operating environment. The February 2023 East Palestine derailment remains the largest operating and reputational event of recent years: the $600 million class action settlement was completed with a final $285 million payment in March 2026, but a class action by six Pennsylvania school districts, other third-party lawsuits, and securities and derivative suits are still pending[14]. On July 28, 2025, the company signed a merger agreement under which Union Pacific will acquire it for one Union Pacific common share plus $88.82 in cash per share; shareholders of both companies approved the deal on November 14, 2025, the transaction still requires approval from the U.S. Surface Transportation Board (STB), and either party owes a $2.5 billion termination fee under specified circumstances[15]. On the management side, Mark George is President and Chief Executive Officer, and Brian Barr succeeded John Orr as Chief Operating Officer on July 1, 2026[4].

The company reports a single segment, railway operations, and discloses revenue by commodity group. Of 2025 revenue of $12.180 billion, merchandise contributed $7.684 billion, or 63%, made up of agriculture, forest and consumer products at $2.538 billion (21%; corn, soybeans, ethanol, lumber, pulp, consumer goods), chemicals at $2.206 billion (18%; natural gas liquids, petroleum products, plastics, industrial chemicals, frac sand), metals and construction at $1.724 billion (14%; steel, scrap, cement, aggregates) and automotive at $1.216 billion (10%; finished vehicles and parts); intermodal contributed $3.009 billion, or 25%, moving domestic and international containers and trailers for intermodal marketing companies, international steamship lines, premium customers and asset-owning companies, with 4.055 million units handled in 2025, of which 2.4502 million were domestic and 1.6048 million international; coal contributed $1.487 billion, or 12%, on 78.05 million tons moved in 2025, of which 33.13 million went to utilities, 31.18 million to export, 9.99 million to domestic metallurgical customers and 3.76 million to industrial users[16]. The coal business directly serves 18 coal-fired power plants, and export coal moves through Lamberts Point in Norfolk, the Port of Baltimore, the McDuffie terminal in Mobile and Lake Erie terminals[12].

Revenue rests physically on volume times rate, and costs concentrate in people, purchased services, fuel and depreciation. In 2025 the company produced 184 billion revenue ton miles at $66.31 of revenue per thousand revenue ton miles[11]; customers pay under contracts, roughly 95% of the revenue base carries negotiated fuel surcharges, and those surcharges move with fuel prices on a formula with a lag[8]. The productive assets are 3,258 locomotives, 36,564 freight cars, 56,391 pieces of intermodal equipment and the company-maintained track, and the railroad consumed 366 million gallons of diesel in 2025[17]. The main cost lines in 2025 were compensation and benefits of $2.922 billion, purchased services of $1.675 billion, fuel of $932 million, depreciation of $1.393 billion, equipment rents of $420 million, materials of $411 million and claims of $281 million; East Palestine costs and insurance recoveries, merger-related expenses and restructuring charges are shown separately, and the company measures its operating ratio on an adjusted basis that excludes them[18]. Collections turn through receivables, working capital was negative $569 million at the end of June 2026, and operating cash flow is the principal source of liquidity[19].

Financial History and Current Position

Over the past three years Norfolk Southern's revenue has barely grown, and profit swings have come mainly from East Palestine costs and insurance recoveries. Railway operating revenues were $12.156 billion in 2023, $12.123 billion in 2024 and $12.180 billion in 2025; GAAP income from railway operations was $2.851 billion in 2023 (including $1.116 billion of incident costs), $4.071 billion in 2024 and $4.356 billion in 2025 (including a $254 million net incident recovery and $80 million of merger costs); net income was $1.827 billion, $2.622 billion and $2.873 billion respectively, and 2025 diluted earnings per share were $12.75[18]. Excluding incident, restructuring and merger items, adjusted income from railway operations was $3.967 billion in 2023, $4.146 billion in 2024 and $4.268 billion in 2025, the adjusted operating ratio improved from 67.4% to 65.8% to 65.0%, and adjusted earnings per share reached $12.49 in 2025, up 5%[20].

The 2025 operating data show that growth came from price rather than volume. Carloads and units totaled 7.0632 million, flat with 2024; average revenue per unit was $1,724, also essentially flat; merchandise carloads rose 2% with revenue per unit up 1%, intermodal units fell 1%, and coal revenue per unit dropped 9%[16]; fuel expense was $932 million, down 6%, on 366 million gallons of diesel[17]. On cash flow, 2025 operating cash flow was $4.361 billion, property additions were $2.204 billion, dividends were $1.215 billion, repurchases were $534 million and stopped after the merger agreement was signed, and year-end cash was $1.530 billion[21], against long-term debt of roughly $16.5 billion[18].

The first quarter of 2026 was a quarter pressed down by winter storms and fuel prices. Revenue of $2.998 billion was flat with the prior year, volume fell 1%, the GAAP operating ratio was 70.7% and the adjusted ratio 68.7%, GAAP earnings per share were $2.43 and adjusted $2.65, and the 10-Q attributed the decline to the absence of the prior year's insurance recoveries, merger costs, inflation and higher fuel prices[22]. Operating cash flow was only $344 million because of the $285 million East Palestine settlement payment made in March[23]. The call described a difficult intermodal market compounded by merger-related volume losses, but the network moved 1.1% more gross ton miles, re-crews fell 8.6% and fuel efficiency hit a record[24].

Second-quarter 2026 revenue was a record, but costs rose faster. Revenue was $3.465 billion, up 11%, on 4% volume growth with fuel surcharges contributing six points; GAAP income from railway operations was $1.124 billion, down 4%, while the adjusted figure was $1.196 billion, up 5%; the GAAP operating ratio was 67.6% and the adjusted ratio 65.5%, 210 basis points worse than the adjusted prior-year quarter; GAAP earnings per share were $3.26 and adjusted $3.52, up 7%[3]. Fuel surcharge revenue was $415 million against $203 million a year earlier[8], and fuel expense was $405 million against $219 million[25]. First-half operating cash flow was $1.398 billion (versus $2.027 billion), property additions were $821 million, dividends $606 million, debt repayments $607 million with no new borrowing, cash at the end of June was $1.069 billion, debt was 50.6% of total capitalization (52.4% at the end of 2025), and $6.3 billion of repurchase authorization remains but is suspended under the merger agreement[19]. Guidance for 2026 is operating expense of $8.8 billion to $8.9 billion (from $8.2 billion to $8.4 billion, with the entire increase from fuel), capital expenditure of approximately $1.9 billion and cost takeout of at least $150 million[4].

Operating Model

Railway operating revenue is the sum across commodity groups of carloads or units multiplied by revenue per unit. In the second quarter of 2026, merchandise was 610.7 thousand carloads times $3,493 for $2.133 billion, intermodal was 1,064.1 thousand units times $853 for $908 million, and coal was 187.3 thousand carloads times $2,264 for $424 million, totaling $3.465 billion[9]. Revenue per unit consists of contract rate, fuel surcharge and commodity mix; roughly 95% of revenue contracts carry fuel surcharges that follow fuel prices on a lagged formula, and second-quarter surcharge revenue of $415 million contributed six of the 11 points of revenue growth[8]. The 10-Q revenue bridge splits each commodity group's year-over-year change into volume, fuel surcharge and rate, mix and other; in the second quarter those were $33 million, $76 million and $52 million for merchandise, $39 million, $123 million and $3 million for intermodal, and $12 million, $13 million and $4 million for coal, and the rate line is the only quarterly evidence of core pricing and mix[8]. Volume drivers differ by group: intermodal depends on domestic shippers shifting from highway to rail (truck capacity and fuel prices) and on international imports, chemicals on production and export of natural gas liquids, petroleum products and frac sand, agriculture and consumer products on corn flows and ethanol demand, metals and construction on aggregate and cement customers' activity, automotive on manufacturers' output and model cycles, and coal on utilities' gas substitution and seaborne coal prices in export markets[26][10].

Income from railway operations equals revenue minus railway operating expenses, and the company measures margin with an adjusted operating ratio that excludes East Palestine, restructuring and merger items: 65.0% in 2025, 68.7% in the first quarter of 2026 and 65.5% in the second[27]. Second-quarter adjusted operating expenses of $2.269 billion consisted of compensation and benefits of $744 million (pay rates up $22 million, incentive and stock-based compensation up $20 million, overtime up $6 million; average headcount down about 320 year over year), purchased services of $435 million, equipment rents of $115 million, fuel of $405 million, depreciation of $358 million, materials of $113 million, claims of $69 million and other of $30 million, within which gains on property sales were only $1 million against $34 million a year earlier[25]. Fuel is the transmission hub of profit: when fuel prices rise, fuel expense rises immediately while surcharge revenue lags, and fuel produced 110 basis points of operating-ratio headwind in the second quarter; when prices fall the direction reverses; inflation (190 basis points in the second quarter) and productivity (a 2026 cost takeout target of at least $150 million, fuel efficiency, fewer re-crews) are the other two forces[4]. Below operating income, interest expense runs about $197 million a quarter and the effective tax rate about 23%, second-quarter GAAP net income was $734 million and adjusted $793 million, and diluted shares were 225 million[27]. Because railroad fixed costs are high, incremental volume carries an above-average marginal contribution, so the direction of volume matters more for profit than for revenue.

Operating cash flow equals net income plus depreciation (about $350 million a quarter) plus deferred taxes, adjusted for working capital, minus cash paid for the incident and litigation. Operating cash flow was $4.361 billion in 2025[21]; in the first half of 2026 it was $1.398 billion, $629 million less than a year earlier, which the 10-Q attributed to higher incident-related cash payments[19], namely the $285 million settlement payment in March[23]. Cash uses in order of priority are property additions ($2.204 billion in 2025, guidance of approximately $1.9 billion for 2026, $821 million in the first half), dividends of about $303 million a quarter ($606 million in the first half) and debt repayment ($607 million in the first half with no new borrowing in 2026)[19]. The merger agreement prohibits repurchases without Union Pacific's consent, buybacks have been suspended since July 2025, $6.3 billion of authorization sits idle, and the company is accumulating cash and repaying debt during the review, with cash of $1.069 billion at the end of June and debt at 50.6% of total capitalization[19]. Property sales generated $253 million of gains in 2025 but only $18 million in the first half of 2026, a supplementary source outside operating cash flow[25]. If the merger closes, the $88.82 per share cash consideration is paid by Union Pacific and does not depend on the company's own cash flow; if it is terminated, the direction of the $2.5 billion termination fee depends on the reason for termination[15].

This model has five visible limits. First, revenue per unit excluding fuel appears only as percentages on the earnings calls, while the 10-Q gives only revenue per unit including fuel and the rate line in the revenue bridge, so core pricing cannot be built into a quarterly numeric series by commodity group[4]. Second, the split of fuel expense between price and consumption appears in the two 2026 10-Qs only as the phrase "higher locomotive fuel prices", so fuel efficiency cannot be quantified[25]. Third, operating metrics (train velocity, terminal dwell, on-time originations, re-crews) exist only as relative changes on the calls, without absolute values[24]. Fourth, merger-related customer diversion exists only as qualitative description and management's "about one point of revenue headwind" framing and cannot be isolated within intermodal units[28]. Fifth, the third-quarter comparison base is the third quarter of 2025, and the materials cited here do not include that quarter's original statements, so readers should rely on the prior-year column in the third-quarter 10-Q.

Industry and Competitive Position

U.S. Class I railroading is a duopoly on each side of the country: Norfolk Southern and CSX in the East, Union Pacific and BNSF in the West. The 10-K names CSX as the primary rail competitor and notes that the two operate throughout much of the same territory; beyond rail-on-rail competition, the company competes with trucks, water carriers and shippers' private carriage, price is only one factor, service reliability, inventory carrying costs and loss and damage matter as well, and intermodal and higher-value goods such as automotive and chemicals are the most service-sensitive[29].

The company's competitive position has two features that numbers can describe. The first is network density: the main corridors run from New York to Chicago, Chicago to Macon and Ohio to Norfolk[11], reaching every major East Coast container port, with the most extensive intermodal network in the East[12]. The second is the trajectory of cost and service: after "PSR 2.0" was introduced in 2024, network train speed rose more than 10% and terminal dwell fell 11%, the 2025 adjusted operating ratio of 65.0% marked a second straight year of improvement, and cost takeout of $216 million in 2025 was followed by a 2026 target raised to at least $150 million[20][4]; yet the second-quarter 2026 adjusted operating ratio of 65.5% still sits above the pre-merger second quarter of 2025 at 63.4%, and the company describes an "industry-competitive margin" relative to peers as a goal rather than a current state[3].

The merger cuts both ways for competitive position. Combining with Union Pacific would create the first single-line transcontinental railroad in the United States, and the two companies say it could shift more than 2 million truckloads off the highway[24]; but during the review, the 10-Q records that certain intermodal customers "have and may continue to diversify their distribution networks, including in response to actions by our competitors"[28], management has said competitor responses created roughly one point of revenue headwind[30], and the 10-K warns that competitors and customers may intervene in the STB proceeding to oppose the application or seek protective conditions[31]. If the merger closes, the company ceases to exist independently; if it fails, the company faces share loss on its own and the question of who pays the $2.5 billion termination fee[15].

Core Debates

Is Norfolk Southern winning back the intermodal freight it lost after the merger announcement, or is the 11% jump in domestic units a fuel-driven one-off?

Intermodal is the company's largest single business and the only one whose revenue fell in 2025, so its direction determines whether the revenue base holds through the merger review. Intermodal was 25% of 2025 revenue[1], the 10-K states plainly that certain customers "diversified their distribution networks in the context of the merger", and the fourth-quarter call acknowledged absorbing roughly one point of company revenue headwind[30]. In the second quarter domestic units rose 11% and intermodal revenue rose 22% to a record $908 million[7][9], but $123 million of the revenue increase was fuel surcharge and the rate line was only $3 million[8]. Whether this business can keep growing without fuel's help is the first question the third quarter must answer.

The evidence for share recovery centers on the truck market and contract structure. Second-quarter domestic units were 668.9 thousand, up 11%, which the 10-Q attributed to rising freight demand and constrained truck capacity[7]; the call cited outbound truck tender rejection rates of 15% overall and 40% for flatbed, multi-year highs, and noted that higher fuel prices make rail cheaper than highway; the company has spent four years restructuring intermodal contracts to be more responsive to spot prices, spot truck price increases typically take 3 to 6 months to flow into contract pricing, management expects the pricing improvement to show through the second half of 2026 and into 2027, and revenue per unit excluding fuel already rose 1% in the second quarter, which management called "the start of a positive shift in intermodal pricing"[4]. The opposite reading is equally documented: first-quarter intermodal units were still down 4% year over year with revenue down 1%[24], the second-quarter jump coincided with the energy-market volatility triggered by the Iran conflict and may be a one-time demand pulse[4]; the rate line in the revenue bridge was only $3 million, so price has not followed volume[8]; international units were 395.2 thousand, down 3%, which the 10-Q attributed to the prior year's pull-forward ahead of anticipated tariff changes[7], and the second-half "business losses" recorded in the 10-K remain[30].

The third-quarter comparison base is the third quarter of 2025, exactly the quarter in which customers began diverting freight, so even growth merely equal to the second quarter's would indicate share coming back, while a return to single digits would mark the second quarter as a fuel- and event-driven outlier. What to watch is the year-over-year change in domestic and international units in the third-quarter 10-Q and whether domestic stays at 8% or above, whether rate, mix and other in the intermodal revenue bridge expands from $3 million to $20 million or more, the year-over-year change in intermodal revenue per unit excluding fuel disclosed on the call and whether management still cites truck tender rejection rates at highs, and whether the 10-Q adds new language about customers diversifying distribution networks or competitor actions[8][28]. The observable falsifiers are: domestic unit growth falling below 5% with the 10-Q attributing it to competitor actions, which would mark the second quarter as a one-time pulse; a negative rate line, which would mean the company is trading price for volume; and continued double-digit declines in international units offsetting domestic gains.

Will the third-quarter fuel tailwind outweigh the July 4% wage increase and inflation and pull the adjusted operating ratio back below 65% from 65.5%?

Railroad profit is almost entirely a function of the operating ratio, and the third quarter is the first in which the fuel reversal and the wage increase overlap. In 2025 the company improved the adjusted operating ratio from 65.8% to 65.0%[20], in the first quarter of 2026 winter storms and fuel prices pushed it to 68.7%[22], and in the second quarter, despite record revenue, the adjusted ratio still worsened 210 basis points year over year to 65.5%, with fuel contributing 110 basis points[3]. Full-year expense guidance has already been raised from $8.2 billion to $8.4 billion to $8.8 billion to $8.9 billion, entirely attributed to fuel[4]. Whether the company delivers on "up to 100 basis points better than seasonal" determines whether the market keeps believing in its cost control.

The evidence for improvement comes from the fuel pass-through mechanism and labor productivity. The second-quarter revenue bridge shows fuel surcharges adding $212 million of revenue[8] while fuel expense rose $186 million[25], 95% of contracts carry surcharges, and when fuel prices fall the surcharge declines later than the expense[8]; management said fuel turns into a tailwind in the third quarter both year over year and sequentially, that core costs excluding fuel sit at the high end of the original range, and reaffirmed at least $150 million of cost takeout in 2026[4]; average headcount was down about 320 year over year while volume grew 4%[25], and the first-quarter call cited record fuel efficiency and 8.6% fewer re-crews[24]. The opposite reading is that inflation has already eaten too much: inflation contributed 190 basis points of deterioration in the second quarter[4], compensation and benefits rose 8% (pay rates up $22 million, incentives up $20 million), the July 4% wage increase adds roughly $30 million more per quarter, and purchased services rose 6%, materials 15% and claims 17%, none of which relates to fuel prices[25]. The first-quarter call had anticipated roughly 200 basis points of sequential improvement in the second quarter[24], and the ratio did improve from 68.7% to 65.5%, delivering on that, but the tailwind then was volume rather than fuel[27].

If the third-quarter adjusted operating ratio lands at 66% or above, the fuel tailwind was consumed by inflation and full-year expense guidance may be raised again. What to watch is whether the third-quarter adjusted operating ratio is no higher than 65.0% and how the results release splits the year-over-year change between fuel and inflation in basis points; whether fuel expense and fuel surcharge revenue move in the same direction and by similar magnitude sequentially; whether compensation and benefits stay within $775 million and how the 10-Q splits pay rates, incentives and headcount; and whether full-year operating expense guidance stays at $8.8 billion to $8.9 billion and the $150 million cost takeout target is reaffirmed[25][4]. The observable falsifiers are: an adjusted operating ratio above 66.0% for reasons other than fuel; surcharge revenue falling faster than fuel expense so that fuel becomes a headwind during the price decline; and another increase in full-year expense guidance.

Is the merchandise business, more than 60% of revenue, showing durable core pricing and chemicals share gains, or did energy-market volatility produce a one-quarter spike?

Merchandise was the only business to grow revenue in 2025 while fuel surcharges fell, and it is the base that holds profit through the merger review. The fourth-quarter call attributed 2025 merchandise revenue growth of $287 million excluding fuel to volume gains and pricing discipline[30]. Second-quarter merchandise revenue was $2.133 billion, up 8%, but $76 million of that came from fuel surcharges; what matters is the $52 million rate, mix and other line and the 10% growth in chemicals carloads[8][9]. With intermodal still recovering share and coal subject to seaborne prices, whether merchandise core pricing persists sets the floor for third-quarter profit.

The evidence for durability is three consecutive reporting periods of volume and price. In 2025 merchandise carloads rose 2% and revenue per unit 1%, and the 10-K said "favorable pricing and mix" offset lower fuel surcharges[30]; in the first quarter of 2026 merchandise volume and revenue each rose 1%, and the call cited continued share gains in chemicals and automotive[24]; in the second quarter chemicals carloads were 153.6 thousand, up 10%, which the 10-Q attributed to domestic and export demand for natural gas liquids and petroleum products and to sand for natural gas drilling[26], the rate, mix and other line rose from zero in the first quarter to $52 million[8][32], and the call said merchandise revenue excluding fuel hit a record with an industrial development pipeline nearly double 2025's[4]. The opposite reading is that growth stands on one leg: the first-quarter call admitted merchandise pricing was "mixed" with revenue per unit excluding fuel flat year over year[24]; second-quarter growth was concentrated in chemicals alone, while agriculture and consumer products fell 1% on corn, metals and construction fell 1% on idled aggregate customers and automotive was flat[26][9]; the call tied the second-quarter gains to the energy-market volatility triggered by the Iran conflict, and that export demand could fade in the third quarter[4]; and the rate line mixes in commodity mix effects, so a rising chemicals share raises it by itself.

The third quarter needs to show chemicals growth holding at 5% or more, the rate line staying at $40 million or more and the other three groups stopping their declines. Specifically, watch whether merchandise rate, mix and other in the third-quarter 10-Q revenue bridge is no less than $40 million, whether chemicals carloads still grow 5% or more year over year and the 10-Q still attributes it to natural gas liquids, petroleum products and sand, whether carloads in agriculture and consumer products, metals and construction and automotive stop falling, and how the call describes merchandise revenue per unit excluding fuel and the industrial development pipeline[8][26]. The observable falsifiers are: chemicals growth falling below single digits with the 10-Q attributing it to weaker export demand; a merchandise rate line below $20 million; and widening declines in the other three groups.

Was the second quarter's 25% surge in export coal tonnage and the first revenue-per-unit increase in two years a one-off seaborne spike, or has the coal business bottomed after two years of decline?

Coal is only 12% of revenue but was the largest drag of the past two years, and its marginal profit exceeds its revenue share. In 2025 coal revenue fell 8% and revenue per unit dropped 9%, and the fourth-quarter call separately identified $108 million of revenue decline from weak seaborne coal prices[30]. In the second quarter export coal rose 25% and revenue per unit turned positive, making coal an addition rather than a subtraction for the first time; but in the same quarter utility coal fell 8% and domestic metallurgical coal fell 15%[10], and management flagged uncertainty in second-half utility demand[4]. The coal corridors run through company-owned terminals such as Lamberts Point[12], incremental tonnage carries high marginal profit, and so this business's direction matters more for third-quarter operating income than its revenue share suggests.

The evidence for a bottom comes from the export market. Second-quarter export coal was 9.349 million tons, up 25%, which the 10-Q attributed to higher global demand for export thermal coal, higher coal production and supportive seaborne pricing[10]; the call said new metallurgical coal export customers are ramping, energy-market volatility is creating incremental thermal export opportunities, revenue per unit excluding fuel rose 1% and seaborne pricing was favorable[4]; and the first-quarter call had already identified export thermal coal as an opportunity to improve the revenue-per-unit mix[24]. The opposite reading is that the drivers all sit outside the company: first-quarter coal revenue per unit was still down 9% year over year[24], the second-quarter turn coincided with the Iran-driven energy-market volatility and thermal exports could disappear as prices retreat[4]; utility coal was 8.577 million tons in the second quarter, down 8%, which the 10-Q attributed to increased natural gas and renewables generation, and domestic metallurgical coal fell 15% on idled customer facilities and reduced equipment availability[10]; and the 2025 reasons for the export decline, "weak global demand and unfavorable seaborne coal pricing", have not gone away[30].

The third quarter needs to show export volume holding double-digit growth, revenue per unit staying positive and the utility decline remaining contained. Specifically, watch the year-over-year change in export and utility tonnage in the third-quarter 10-Q coal table and whether the attribution is still supportive seaborne pricing, whether coal revenue per unit is up year over year and how the call describes revenue per unit excluding fuel and commodity mix, whether the 10-Q adds new language on idled export customers, terminal or equipment availability, and how the call judges second-half utility demand and natural gas prices[10][9]. The observable falsifiers are: export tonnage turning negative year over year with the attribution on seaborne pricing; another year-over-year decline in revenue per unit; and the utility decline widening to 15% or more.

Risks and Falsifiers

The first risk is that the Union Pacific merger remains under STB review, and the opposition has become concrete. The STB adopted a procedural schedule on August 18, 2026 (comments due November 18, replies due February 16, 2027) and on September 18 denied opponents' motion for summary rejection, but BNSF, CSX, CPKC and the attorneys general of seven states have filed oppositions or requests for conditions, and the company expects completion in the second half of 2027[33][34]. During the review the company carries roughly $50 million of merger costs a quarter ($80 million in 2025, $103 million in the first half of 2026), cannot repurchase shares, leaves $6.3 billion of authorization idle, has management attention diverted, and has already absorbed a revenue headwind from customer and competitor reactions[33][35][28]; if the STB imposes heavy conditions or rejects the deal, the company faces share loss on its own, and the direction of the $2.5 billion termination fee depends on the reason for termination[31][15]. The falsifier is that the merger note and forward-looking statements in the third-quarter 10-Q add no new language on review delays, conditions or customer diversion, and merger costs do not exceed $60 million.

The second risk is the legacy liability and cash outflow from East Palestine. The $600 million class action settlement was completed with the final $285 million in March 2026, but the class action by six Pennsylvania school districts, other third-party suits, and securities and derivative suits are still pending, with the motions to dismiss not yet decided[14]; incident-related costs were $25 million in the first half of 2026 against a $232 million net insurance recovery a year earlier, and that comparison base distorts year-over-year GAAP profit for all of 2026[25]; incident costs were $1.116 billion in 2023, $325 million in 2024 and a net recovery of $254 million in 2025[18], and first-half operating cash flow of $1.398 billion was $629 million lower than a year earlier, mainly because of the settlement payment[19]. A new ruling or regulatory requirement would generate cash outflows again, and the falsifier is that the incident note in the third-quarter 10-Q adds no new settlement, ruling or regulatory order and net incident costs do not exceed $20 million.

The third risk is that intermodal share recovery depends on tight truck capacity, an external condition. If spot truck prices retreat or competitors again compete on price for Southeast freight, domestic unit growth would fade before contract repricing arrives, repeating the revenue headwind of the second half of 2025[30][28]. The exposed financial line is second-quarter intermodal revenue of $908 million: at the second-quarter revenue per unit of $853, each percentage point of domestic units is roughly $5.7 million of quarterly revenue[9][7]. The falsifier is third-quarter domestic unit growth of at least 8% with no new 10-Q language on customer diversion or competitor actions.

The fourth risk is that the surcharge lag could make fuel a headwind in some quarter as prices fall, while non-fuel inflation leaves no slack. Second-quarter fuel expense was $405 million and surcharge revenue $415 million, a gap of only $10 million[25][8]; within full-year operating expense guidance of $8.8 billion to $8.9 billion, the fuel increment is $400 million to $500 million, and the company's statement that "core costs excluding fuel are at the high end of the original range" already implies no room in expenses[4]; each 100 basis points of adjusted operating ratio equals roughly $35 million of quarterly operating income at second-quarter revenue[3]. The falsifier is a third-quarter adjusted operating ratio no higher than 65.0% with fuel expense and surcharge revenue both declining sequentially.

The fifth risk is that merchandise growth currently rests on a single commodity group, chemicals. The chemicals increment appeared alongside energy-market volatility, and export demand for natural gas liquids and petroleum products could fade as oil prices retreat; metals and construction is weighed down by idled aggregate customers, agriculture and consumer products by corn flows, and automotive by production downtime and model discontinuations[26]. The exposed financial line is second-quarter chemicals revenue of $646 million, 30% of merchandise revenue of $2.133 billion; at the second-quarter revenue per unit of $4,206, each percentage point of chemicals carloads is roughly $6.5 million of quarterly revenue, and the other three groups total $1.487 billion[9]. The falsifier is third-quarter chemicals carload growth of at least 5% with combined carloads in the other three groups no longer declining year over year.

The sixth risk is that both of coal's largest markets are driven from outside the company. Export coal gains depend on seaborne thermal prices and global energy-market volatility, utility coal is squeezed by natural gas prices and renewables, and once seaborne prices retreat the 2025 combination of "export decline plus falling revenue per unit" would repeat[10][30]. The exposed financial line is second-quarter coal revenue of $424 million: export coal of 9.349 million tons was 44% of total tonnage of 21.187 million, each 1% of revenue per unit equals roughly $4.2 million of quarterly revenue at 187.3 thousand second-quarter carloads[9][10], and the revenue decline from weak seaborne pricing in 2025 was $108 million on the fourth-quarter call's framing[30]. The falsifier is third-quarter export tonnage growth of at least 10% with coal revenue per unit up year over year.

What to Watch Next

The four core debates and the cross-cutting risks compress into metrics the third-quarter report can be checked against directly[9][25][4].

• Intermodal share recovery: domestic intermodal units, currently 668.9 thousand and up 11% in the second quarter of 2026. Watch whether domestic growth stays at 8% or above and whether the international decline narrows. Growth below 5% with the 10-Q blaming competitor actions falsifies the recovery reading.
• Intermodal share recovery: the rate, mix and other line in the intermodal revenue bridge, currently a $3 million year-over-year increment. Watch whether it expands to $20 million or more. A negative rate line falsifies it.
• Fuel pass-through and operating ratio: the adjusted railway operating ratio, currently 65.5%. Watch whether it is no higher than 65.0% and how the basis points split between fuel and inflation. A ratio above 66.0% for reasons other than fuel falsifies it.
• Fuel pass-through and operating ratio: fuel expense of $405 million and compensation and benefits of $744 million. Watch whether fuel expense and surcharges fall together and whether compensation stays within $775 million. Surcharges falling faster than fuel expense falsifies it.
• Merchandise core pricing: chemicals carloads of 153.6 thousand (up 10%) and a merchandise rate line of $52 million. Watch whether chemicals growth holds at 5% and the rate line stays at $40 million or more. Chemicals falling below single digits or a rate line under $20 million falsifies it.
• Coal bottoming: export tonnage of 9.349 million tons (up 25%) and coal revenue per unit of $2,264. Watch whether exports keep double-digit growth and revenue per unit is up year over year. Exports turning negative on seaborne pricing, or revenue per unit falling again, falsifies it.
• Merger review: merger costs of roughly $50 million a quarter and the 10-Q merger note. Watch for new language on review delays, conditions or customer diversion. No new language and costs no higher than $60 million confirms the current reading.
• East Palestine legacy: net incident costs of $25 million in the first half and the litigation note. Watch for new settlements, rulings or regulatory orders. None, with net costs no higher than $20 million, confirms it.

Conclusion

Norfolk Southern's revenue is built from three commodity groups' volume times revenue per unit, and its profit is set by the adjusted operating ratio, and the second-quarter 2026 picture is record revenue with a retreating margin: revenue of $3.465 billion, up 11%, of which six points came from fuel surcharges, and an adjusted operating ratio of 65.5%, 210 basis points worse year over year, with fuel and inflation contributing 110 and 190 basis points respectively[3][4]. The balance sheet has turned conservative during the merger review, with first-half operating cash flow of $1.398 billion, debt repayment of $607 million and no new borrowing, cash of $1.069 billion at the end of June, debt at 50.6% of total capitalization and buybacks suspended under the merger agreement[19]. The central third-quarter relationship is where the operating ratio lands after the fuel tailwind, the 4% wage increase and inflation net against each other, and how much of the 11% growth in domestic intermodal, the 10% growth in chemicals and the 25% growth in export coal survives once the energy-market volatility recedes.

Outside interpretations published after the results point in two directions and do not judge the same thing. Sanjana Goswami of Zacks Investment Research, on July 30, characterized the second quarter as a "strong earnings beat", noting revenue up 11% to a record $3.47 billion and a full-year earnings estimate raised 3.9% over four weeks, but raised three reservations: the stock trades at 25.17 times forward 12-month earnings, above the industry average of 21.77 and near the top of its own historical range, buybacks are suspended because of the Union Pacific merger agreement, and cost inflation and service execution remain risks, concluding that the stock appeals mainly to momentum investors rather than value-oriented buyers[36]. Joshua Fineman of Seeking Alpha, on September 1, recorded the clearest outside opposition during the review: the attorneys general of Montana, Iowa, Kansas, Florida, North Dakota, South Dakota and Tennessee asked regulators to reject the revised merger application on the grounds that "the merged entity is not clearly in the public interest", and shares of Union Pacific and Norfolk Southern fell after the announcement[34]. The two views intersect on merger uncertainty: Zacks locates it in the buyback suspension, Seeking Alpha in the review outcome; the full-year estimate increase Zacks describes means consensus has already priced in "fuel tailwind covers the wage increase", so if the third-quarter adjusted operating ratio comes in above 65.5%, the room for a beat disappears. Both are outside interpretations rather than facts, and neither directly judges the four operating debates.

The combination that would clearly strengthen the current understanding is: a third-quarter adjusted operating ratio no higher than 65.0% with fuel and surcharges falling together, domestic intermodal unit growth of at least 8% with the rate line expanding to $20 million or more, chemicals carload growth of at least 5% with a merchandise rate line of at least $40 million, export coal growth of at least 10% with revenue per unit up year over year, and no new adverse language in the 10-Q's merger and incident notes. The combination that would clearly weaken it is: an adjusted operating ratio above 66.0% for reasons other than fuel, domestic unit growth falling below 5% and attributed to competitor actions, a merchandise rate line below $20 million, export coal turning negative on seaborne pricing, or a fresh jump in either merger costs or incident costs[25][8].
