Problem Definition
Atlas Rail is a large freight railroad whose network covers the western half of North America, with about 20,000 route miles linking West Coast ports, the Gulf and the Midwest. It generated $9.0 billion of revenue last year at an operating ratio (operating expenses divided by revenue) of 62%, so operating income was about $3.4 billion. Its main traffic is intermodal containers, chemicals, grain, automotive and industrial products.
Atlas's CEO wants to acquire Eastmark Railway, an eastern peer with about 17,000 route miles, $6.0 billion of revenue and a weaker operating ratio of 68%. The two networks meet at only two gateway cities (Chicago and Memphis). Today, freight moving coast to coast must be handed from one railroad to the other at those gateways, which adds one to two days of transit time. Combining them would create a single-line transcontinental railroad.
The industry context is favourable but uncertain. In July 2025, Union Pacific and Norfolk Southern announced an approximately $85 billion merger promising about $2.75 billion of annual synergies. It is the first major rail merger reviewed under the Surface Transportation Board's (STB) 2001 merger rules, which require that mergers between large railroads enhance competition, not merely preserve it. That review is still ongoing, with a decision expected in 2027.
Eastmark's unaffected enterprise value (EV) is about $28 billion. Its board has signalled that it would engage at an EV of about $35 billion, a 25% premium. Atlas's board has hired your team. How much are the synergies worth, and what is the most Atlas should pay for Eastmark?
Additional InformationAsk for dataInterviewer’s data
If asked, please share that:
- Both railroads are profitable, investment grade and roughly equally leveraged
- Atlas has about 12,700 employees and Eastmark about 9,700; railroad workers are unionised, and average total pay and benefits for a large U.S. railroad employee are about $135,000-190,000 per year
- Eastmark's operating ratio lags peers mainly because of older yards, lower train lengths and higher crew costs per train
- Across the industry, large freight railroads privately invest about $23 billion a year in their networks, and rail moves one ton of freight nearly 500 miles on a gallon of fuel
- Historically, big rail mergers have caused serious service failures during integration (e.g., the Union Pacific-Southern Pacific congestion in Houston in 1997-98, and Norfolk Southern's IT-driven service problems after the 1999 Conrail split)
Question 1Structuring
How would you structure an assessment of whether Atlas should acquire Eastmark, and at what price?
Hint · Structuring
Build 3–4 branches that are specific to this client and question, not a generic framework. Check they don't overlap and together cover the problem.
Additional InformationAsk for dataInterviewer’s data
- Confirm the two headline numbers: unaffected EV of $28B and the $35B asking price
- If asked, the board cares about value per Atlas share, regulatory approval, and not repeating past merger service failures
Try it first, then checkCheck my answerModel answer
1. Standalone value
- a) Eastmark's current earnings and the gap to peer operating ratios
- b) Is some of the "synergy" really just improvement Eastmark could make on its own?
2. Synergies
- a) Cost: overlapping overhead and management, procurement, equipment and yard consolidation, fuel efficiency from longer, run-through trains
- b) Revenue: truck-to-rail conversion on new single-line lanes, diversion from competing rail routes, better service
- c) Dis-synergies: traffic lost from other railroads that currently hand cars to either company and may reroute
- d) One-time integration costs (IT systems, yard rebuilds, labour agreements)
3. Price and value creation
- a) Premium paid ($35B - $28B = $7B) vs. present value of net synergies
- b) Walk-away price
- c) Deal structure: cash vs. stock, termination fees
4. Risks
- a) Regulatory: STB approval, possible conditions, timing
- b) Integration: service disruption, IT cutover, labour relations
- c) Market: freight volumes, trucking competition, fuel prices
What the interviewer is looking forInterviewer’s viewInterviewer’s view
This is a classic synergy-versus-premium problem with a heavy regulatory overlay. After the candidate presents, steer them to cost synergies first (Question 2).
- Good candidates split the problem into standalone value, synergies and price
- Strong candidates split synergies into cost, revenue and dis-synergies, and include one-time integration costs
- Excellent candidates treat regulation as a value driver, not a footnote: the STB can impose conditions (for example, access for rival railroads) that remove part of the synergies, and the review itself delays when synergies start. They also recognise that the premium goes to Eastmark's shareholders on day one, while synergies are uncertain and arrive later
Question 2Numeracy
Using Exhibit 1, estimate the annual run-rate cost synergies. How does your number compare with the Union Pacific-Norfolk Southern announcement?
Hint · Numeracy
Write the formula before you plug in numbers, keep units and zeros explicit, and sanity-check the order of magnitude at the end.
Exhibit 1Combined Operating Cost Base ($M, last fiscal year)
| Cost category | Atlas | Eastmark | Combined | Synergy assumption |
|---|---|---|---|---|
| Compensation and benefits | 1,900 | 1,450 | 3,350 | 5% |
| Fuel | 820 | 520 | 1,340 | 2% |

Additional InformationAsk for dataInterviewer’s data
- Share Exhibit 1 with the synergy percentages
- If asked: depreciation is excluded from synergies because the combined network keeps all main lines
- If asked for the benchmark: Union Pacific reported about $14.7 billion of operating expenses in 2025 and Norfolk Southern about $7.8 billion; the companies announced about $1 billion of cost and productivity savings
Try it first, then checkCheck my answerModel answer
Step 1: Synergies by category
| Category | Combined ($M) | Synergy % | Savings ($M) |
|---|---|---|---|
| Compensation and benefits | 3,350 | 5% | 167.5 |
| Fuel | 1,340 | 2% | 26.8 |
| Purchased services and rents | 2,000 | 6% | 120.0 |
| Depreciation | 1,650 | 0% | 0 |
| Materials and other | 1,320 | 5% | 66.0 |
| Total | 9,660 | 3.9% | ~380 |
Step 2: Benchmark against UP-NS
- UP-NS combined operating expenses: about $14.7B + $7.8B = about $22.5B
- Announced cost savings: about $1B, which is about 4.4% of the combined cost base
- Atlas-Eastmark: $380M / $9,660M = 3.9%
- The estimate is slightly more conservative than the precedent, which is appropriate for a first estimate
Step 3: Implications
- Compensation savings of $167.5M at about $150,000 per employee means about 1,100 roles, about 5% of the combined 22,400 workforce. (For scale, the UP-NS application projected 1,138 layoffs.)
- Pro forma operating ratio on cost synergies alone: ($9,660M - $380M) / $15,000M = 61.9%, compared with 64.4% combined today
What the interviewer is looking forInterviewer’s viewInterviewer’s view
Check that the candidate first combines the cost bases, applies the percentages category by category, and then sanity-checks the total against a benchmark.
"So What?" cascade:
- Level 1 (surface): Cost synergies are about $380M a year
- Level 2 (implication): That is about 3.9% of the combined cost base, a bit below the approximately 4.4% implied by the UP-NS announcement, so the estimate looks reasonable and not aggressive
- Level 3 (actionable): Almost half of the savings (about $168M) come from compensation, meaning roughly 1,100 fewer roles. That is a labour and regulatory issue as much as a financial one, and must be managed through attrition and negotiated agreements
Question 3Numeracy
The deal team also expects revenue synergies (Exhibit 2). Estimate the net annual operating income from revenue synergies. Then tell me what you think of how UP-NS described its "$2.75 billion of synergies".
Hint · Numeracy
Write the formula before you plug in numbers, keep units and zeros explicit, and sanity-check the order of magnitude at the end.
Exhibit 2Revenue Synergy Estimates (Run-Rate, Year 4)
| Opportunity | Units per year | Average revenue per unit | Incremental margin |
|---|---|---|---|
| Truck-to-rail conversion on new single-line intermodal lanes | 150,000 | $2,000 | 40% |
| Diversion from competing rail routes | 80,000 | $2,500 | 55% |
| Traffic lost from rival railroads that reroute (dis-synergy) | -40,000 | $2,200 | 55% |
Source: Atlas deal team estimates. Units are carloads or containers.
Source: Atlas Rail case file
Additional InformationAsk for dataInterviewer’s data
- Share Exhibit 2
- The incremental margin is the share of each extra dollar of revenue that becomes operating income (the network already exists, so most costs are fixed; margins are lower for intermodal because of drayage and terminal costs)
- For UP-NS, the $2.75 billion headline combined about $1.75 billion of additional revenue with about $1 billion of cost and productivity savings
Try it first, then checkCheck my answerModel answer
Step 1: Revenue by opportunity
- Truck conversion: 150,000 x $2,000 = $300M
- Rail diversion: 80,000 x $2,500 = $200M
- Lost traffic: -40,000 x $2,200 = -$88M
- Net revenue synergy: $300M + $200M - $88M = $412M
Step 2: Operating income
- Truck conversion: $300M x 40% = $120M
- Rail diversion: $200M x 55% = $110M
- Lost traffic: -$88M x 55% = -$48.4M
- Net operating income from revenue synergies: ~$181.6M, about $182M
Step 3: Total synergies and pro forma operating ratio
- Cost synergies $380M + revenue synergy income $182M = ~$562M of annual operating income
- Pro forma revenue: $15,000M + $412M = $15,412M
- Pro forma costs: $9,660M - $380M + ($412M - $181.6M) = $9,510M
- Pro forma operating ratio: $9,510M / $15,412M = ~61.7%
Step 4: The UP-NS headline
- $1.75B of revenue plus $1B of savings = $2.75B, but the two parts are not the same kind of number
- If UP-NS's revenue synergies earned a similar ~45-50% incremental margin, they would add roughly $0.8-0.9B of operating income, so total profit synergies would be closer to $1.8-1.9B than $2.75B
- Takeaway for Atlas: always state synergies in operating income before comparing them with the premium
What the interviewer is looking forInterviewer’s viewInterviewer’s view
There are two parts: a calculation and an insight. The insight is that the UP-NS headline adds revenue to cost savings, which mixes a top-line figure with a profit figure. The candidate should convert revenue synergies to operating income before comparing them with the price.
"So What?" cascade:
- Level 1 (surface): Net revenue synergies of $412M add about $182M of operating income
- Level 2 (implication): Revenue synergies are worth less than half of what their top-line figure suggests, and they are the least certain part of the case because they depend on winning traffic from trucks and rivals
- Level 3 (actionable): When comparing synergies with the premium, use operating income, not revenue, and apply a risk haircut to revenue synergies. Headline synergy numbers like "$2.75B" overstate value if read as profit
Question 4Numeracy
Is a $35 billion price justified by the synergies? Use the assumptions below.
Hint · Numeracy
Write the formula before you plug in numbers, keep units and zeros explicit, and sanity-check the order of magnitude at the end.
Additional InformationAsk for dataInterviewer’s data
- Tax rate on synergies: 25%
- Value synergies as a growing perpetuity: after-tax synergies / (discount rate - growth rate), with a discount rate of 8% and long-term growth of 2%
- One-time integration costs: about $600M (IT systems, yard rebuilds, labour agreements, rebranding)
- Ignore ramp-up time for now (it comes up in Question 5)
Try it first, then checkCheck my answerModel answer
Step 1: After-tax synergies
- Pre-tax synergies: $380M + $182M = $562M (using $181.6M: $561.6M)
- After tax: $561.6M x (1 - 25%) = ~$421M per year
Step 2: Value of synergies
- $421M / (8% - 2%) = $421M / 0.06 = ~$7.0B
Step 3: Net of integration costs
- $7.0B - $0.6B = ~$6.4B
Step 4: Compare with the premium
| Item | Value |
|---|---|
| Asking price (EV) | $35.0B |
| Unaffected EV | $28.0B |
| Premium | $7.0B |
| Net value of synergies | ~$6.4B |
| Value created (destroyed) for Atlas | ~-$0.6B |
Step 5: Reality check on the multiple
- Eastmark operating income: $6.0B x (1 - 68%) = $1.92B
- EBITDA: $1.92B + $0.65B depreciation = $2.57B
- $35B / $2.57B = ~13.6x EBITDA, vs. ~10.9x unaffected ($28B / $2.57B)
Conclusion: At $35B, Atlas would hand Eastmark's shareholders the entire value of the synergies and more. The price is not justified on these assumptions.
What the interviewer is looking forInterviewer’s viewInterviewer’s view
The key comparison is premium vs. net present value of synergies. Many candidates compare the premium with annual synergies, or forget taxes or integration costs.
"So What?" cascade:
- Level 1 (surface): Synergies are worth about $6.4B net of integration costs
- Level 2 (implication): The $7B premium is higher than that, so at $35B Atlas pays Eastmark's shareholders more than 100% of the synergies, even before any regulatory haircut
- Level 3 (actionable): At $35B the deal would destroy about $0.6B of value for Atlas shareholders. The walk-away price must be set below $35B, and it drops further once regulatory risk is included
Question 5Judgement & Insights
Now bring in regulation and timing. Look at Exhibit 3. How do they change the value of the deal, and which risks worry you most?
Hint · Judgement & Insights
Read the exhibit title, axes and units first. Lead with the ‘so what’, then back it with one or two numbers.
Exhibit 3Regulatory and Integration Risk Map
| Issue | Detail | Likelihood | Impact |
|---|---|---|---|
| 2-to-1 customers | 120 shipper facilities served today only by Atlas and Eastmark; about $400M of annual revenue | High that the STB imposes a remedy | Loss of part of this revenue |
| Review duration | Precedent (UP-NS) suggests about two years from announcement to STB decision | High | Synergies delayed |
| "Enhance competition" test | 2001 rules require the merger to enhance competition; UP-NS is the first test case | Medium | Extra conditions or rejection |
| Integration service failure | Past large mergers (UP-SP 1997-98, Conrail split 1999) caused months of congestion | Medium | Lost customers, reputational damage |
| Labour | About 1,100 roles affected; unions may oppose | Medium | Delay, higher one-time costs |

Additional InformationAsk for dataInterviewer’s data
- Share Exhibit 3
- If asked: under the 2001 merger rules the STB can impose conditions, such as giving a rival railroad access (trackage rights) to customers who would otherwise go from two railroads to one. Assume the STB grants rival access to the "2-to-1" customers and Atlas loses 30% of that revenue, at a 50% margin
- If asked: the UP-NS timeline suggests about two years from announcement to decision. Its application was filed in December 2025, rejected as incomplete in January 2026, and accepted in May 2026, with a decision expected in 2027
- Assume synergies start two years later than planned, so their present value is divided by 1.08 x 1.08 = 1.1664
Try it first, then checkCheck my answerModel answer
Effect 1: STB remedy on 2-to-1 customers
- Revenue lost: $400M x 30% = $120M
- Operating income lost: $120M x 50% = $60M per year
- After tax: $60M x 75% = $45M; value: $45M / 0.06 = ~$0.75B
Effect 2: Two-year delay
- Synergy value: $7.02B / 1.1664 = ~$6.0B (from $7.0B)
- Remedy value delayed as well: $0.75B / 1.1664 = ~$0.64B
Revised value
| Item | No delay | With two-year delay |
|---|---|---|
| Value of synergies | $7.0B | $6.0B |
| Less STB remedy | -$0.75B | -$0.64B |
| Less integration costs | -$0.6B | -$0.6B |
| Net synergy value | ~$5.7B | ~$4.8B |
| Walk-away EV ($28B + net synergies) | ~$33.7B | ~$32.8B |
Which risks matter most (judgement)
- Integration execution. The UP-SP and Conrail experiences show that a failed cutover can erase a year of synergies and push customers back to trucks. This is the risk least captured in the numbers
- Revenue synergies. At $182M, they are about a third of total synergies and depend on customers changing behaviour; a 50% haircut ($91M pre-tax, about $68M after tax) removes about $1.0B of value after delay ($68M / 0.06 / 1.1664)
- Regulatory precedent. Atlas's application will be judged partly on how the STB rules on UP-NS. If that deal is approved with heavy conditions, expect similar conditions here
What the interviewer is looking forInterviewer’s viewInterviewer’s view
Look for the candidate to quantify both effects, then step back to judgement: the biggest risk is not arithmetic but integration execution, which history shows can wipe out synergies and damage customer relationships.
"So What?" cascade:
- Level 1 (surface): STB conditions cost about $60M a year; delay cuts the value of synergies by about 14%
- Level 2 (implication): Net synergy value falls from about $6.4B to about $4.8B, so the walk-away price falls to about $32.8B, well below the $35B ask
- Level 3 (actionable): Atlas should bid below $33B, avoid overlapping ("2-to-1") customers where possible by offering remedies up front, and insist on deal protections. It should also build an integration plan that avoids a big-bang IT cutover
Question 6Synthesis
The Atlas board meets tomorrow. What is your recommendation?
Hint · Synthesis
Answer first: the recommendation, two or three reasons with numbers, then risks and next steps.
Try it first, then checkCheck my answerModel answer
Recommendation: Pursue Eastmark, but do not pay $35 billion. Offer up to about $32 billion EV and walk away above about $33 billion.
Why
- The synergies are real but finite. About $380M of cost and $182M of revenue-driven operating income, about $562M a year in total. That is worth about $7.0B before costs and risks
- At $35B Atlas gives away more than the synergies. Net of integration costs, synergies are worth about $6.4B vs. a $7B premium
- Regulation and timing reduce value further. The likely STB remedy and a two-year review cut net synergy value to about $4.8B, a walk-away EV of about $32.8B
How to bridge the gap with Eastmark
- Part stock consideration, so Eastmark shareholders share in synergy upside and risk
- Offer remedies up front (for example, voluntary access for a rival railroad at the 120 "2-to-1" facilities) to strengthen the "enhance competition" case and shorten the review
- Reverse termination fee of about 3% of EV (about $1B at $33B), similar to the approximately $2.5B fee (about 3% of $85B) in the UP-NS agreement. This signals commitment without open-ended exposure
Integration plan (to protect the synergies)
- Run the two railroads separately until approval, then integrate operations corridor by corridor over 18-24 months
- No big-bang IT cutover; test run-through trains at Chicago and Memphis first
- Reach job-protection agreements with unions early, relying mostly on attrition for the ~1,100 role reductions
- Publish service metrics (car velocity, dwell time) to shippers and the STB during integration
Key risks and mitigants
- STB rejects or delays beyond 2027: termination fee cap and a clear end date in the merger agreement
- Revenue synergies underdeliver: at $32B (a $4B premium), a 50% shortfall in revenue synergies cuts net synergy value to about $3.8B, roughly break-even. That is why Atlas should not go above about $32-33B and should use part stock consideration to share this risk
- Service meltdown: phased integration, extra crews and locomotives held in reserve during cutover
What the interviewer is looking forInterviewer’s viewInterviewer’s view
Look for a clear go/no-go with a price, supported by the numbers, plus the conditions and protections that make the recommendation hold. Excellent candidates propose ways to bridge the gap with Eastmark's $35B ask without overpaying (for example, part stock so Eastmark shareholders share synergy risk, or a contingent payment tied to STB approval terms), and mention a reverse termination fee in line with precedent.
