Declining industry and turnaround

The business is shrinking: separate the company from the industry, fix what is fixable, and, when the whole industry is declining, manage the decline for cash.

Key takeaways

  • First decide whether this is a company problem or an industry problem, because the realistic answer differs completely, and do not promise growth in an industry that cannot support it.
  • Restructuring and turnaround practices push hardest here. Expect to be asked when exit is the right answer, which tests judgment over optimism.
  • The strong answer locates the cause and matches the answer to it. The weak one gives the same answer to two very different problems.
  • Why a generic structure scores lower: Recommending general cost cuts, or growth, before checking whether the industry or the company is the problem gives the wrong answer half the time.

What this case type is and when it shows up

A turnaround case has a business that is struggling or shrinking. The first cut is whether the company is declining faster than its industry (a company problem you can fix) or whether the whole industry is declining (a different, harder question).

The underlying theory, in plain language

Always separate the company from the industry. If the industry is flat but the company is losing share, the problem and the fix are internal. If the whole industry is shrinking, even a well-run company cannot grow against it, and the honest answer may be to manage the decline, harvest cash, consolidate with rivals, or exit.

Turnarounds usually combine stopping the losses (cost and cash) with finding a narrower space where the company can still win. Cash runway, the months of cash left at the current loss rate, sets how much time there is.

In a declining business, fixed costs are the danger: as revenue falls, fixed costs take a larger share, and profit falls faster than revenue. Break-even revenue is fixed costs divided by (1 minus variable costs as a share of revenue). Cutting fixed costs in step with revenue keeps the business profitable for longer.

What the prompts sound like, from simple to hard

  • Simple: a fashion retailer in Germany is losing money; what now.
  • Medium: a company is losing share in a flat market.
  • Hard: a UK printed-directory business in an industry that is moving online.

Build the structure from the goal

Three moves that give you the structure

  1. 1Start from the decision. What should the owner do with a business whose sales keep falling: fix it, run it for cash, combine with a rival, or exit?
  2. 2Write the maths of the goal. Company change in sales = industry change + the change in the company's share. Profit = revenue x contribution margin minus fixed costs, so break-even revenue = fixed costs / contribution margin, and the rate of decline tells you when it is reached.
  3. 3Let the business pick the branches. The industry tells you whether a niche exists. Printed directories and film cameras lost almost all demand, so the answer is cash and an orderly exit. Department stores lost much but kept some loyal shoppers, so a smaller format can survive. A retailer losing share while its industry grows has a company problem that can be fixed.
Same type, different case 1: a newspaper publisher whose print sales fall 8 percent a year
  • Fix, harvest, or exit?
    • Industry or company: our fall versus all newspapers
    • Key: Print profit path: break-even revenue, and when we reach it
    • Digital subscribers: can they replace print profit?
    • Harvest: cut printing and delivery cost

This comes from profit = revenue x margin minus fixed costs. Print is falling across the industry, so the break-even date sets the timetable for every other choice.

Same type, different case 2: a toy retailer losing sales while the toy market grows
  • Why are we losing share, and can we fix it?
    • Industry growth versus ours
    • Key: Lost share by channel: stores versus online
    • Price and range versus rivals
    • Store costs and leases that can be cut

Same maths, a different answer. The industry is growing, so this is a company problem, and the channel where share is lost leads.

Why a generic structure scores lower

Recommending general cost cuts, or growth, before checking whether the industry or the company is the problem gives the wrong answer half the time. The interviewer scores that first split.

Crack any case in five moves

Finding and narrowing the real problem

Key idea

First decide whether this is a company problem or an industry problem, because the realistic answer differs completely, and do not promise growth in an industry that cannot support it.

Names you may hear, kept as questions that fall out of the goal maths

  • Company versus industry: Is our fall bigger than the industry's? This is the first split of the goal maths. Where it stops helping: Needs industry data; without it, you are guessing the cause.
  • Stabilize, then reposition: Can we stop losing cash now, and is there a group of customers we can keep profitably? Where it stops helping: Some declines have no viable niche, and the answer is an orderly exit.
  • Fix, harvest, consolidate, exit: Which end state gives the owner the most value, given its goal: cash, value, or survival? Where it stops helping: The choice depends on the owner's goal, so ask for it.

Methods for solving this type

  • Compare company and industry trends
  • Check cash runway
  • Stop the cash losses
  • Find a defensible niche or segment
  • Model the decline and choose between fixing, harvesting, consolidating, and exiting

The math patterns it relies on

  • Company growth versus industry growth
  • Cash runway = cash / monthly loss
  • Break-even revenue = fixed costs / (1 minus variable cost share)
  • Revenue after several years of decline

Worked cases

Worked case

Company problem or industry problem?

The prompt

A German fashion retailer's sales fell 12 percent last year while its industry fell 4 percent. The table below splits the company's sales and the industry's change by channel. Is this mainly a company problem or an industry problem, and where is it?

Interviewer-led: the interviewer shows the channel table and asks how much of the fall is the company's own, then which channel explains it.

Clarifying questions, with the interviewer's answers

  1. Is the industry figure for the same products and regions?Answer: Yes, mid-price fashion in Germany.
  2. Did the company close stores?Answer: No, the store count did not change.

A hypothesis to say out loud: The company fell three times faster than its industry, so my hypothesis is that most of the decline is lost market share, which is a company problem we can fix.

The structure

  • Compare the two declines, then find the channelThis comes from the company's change in sales = the industry's change + the change in our share, by channel.
    • Industry decline
    • Key: Company decline beyond the industry
      • Stores: falling faster than the industry
      • Online: not growing while the industry grows

The exhibit

ChannelCompany sales last year (EUR m)Company sales this year (EUR m)Industry change (%)
Stores400340-9
Online10010016
Total500440-4

Working it through

  1. 1. Excess decline

    The company fell 12 percent while the industry fell 4 percent, so about 8 of the 12 points are specific to the company.

    Company-specific decline (points):12 - 4 = 8
  2. 2. A more exact view

    The subtraction is a quick shortcut. More precisely, the company's market share fell by 1 minus 0.88/0.96, which is about 8.3 percent, so the shortcut holds.

    Loss of market share (%):(1 - 0.88 ÷ 0.96) × 100 = 8.33
  3. 3. The gap in money

    Had the company moved with its industry, sales would be EUR 480 million, not 440.

    Gap to industry pace (EUR m):500 × (1 - 0.04) - 440 = 40
  4. 4. Stores

    At the industry's minus 9 percent, stores would have sold EUR 364 million instead of 340.

    Store gap (EUR m):400 × (1 - 0.09) - 340 = 24
  5. 5. Online

    At the industry's plus 16 percent, online would have sold EUR 116 million instead of 100. Stores and online together explain the full 40.

    Online gap (EUR m):100 × 1.16 - 100 = 16

What the exhibit shows

The company fell faster than the industry in stores and did not grow at all online while the industry's online sales grew 16 percent.

The recommendation

This is mainly a company problem with a real fix. First, about two thirds of the decline (8 of 12 points) is lost share, not the industry. Second, in money the company is EUR 40 million below where it would be at industry pace, and EUR 24 million of that is stores falling faster than rivals' stores. Third, the other EUR 16 million is online: the company's online sales did not grow at all while the industry's grew 16 percent. Diagnose why store customers are leaving (price, range, or store experience) and why the online offer is not growing, before treating this as an unavoidable industry decline.

Risks: The industry decline may speed up, adding pressure; Some of the store gap may come from store locations that no fix can save.

Next steps: Compare price, range, and online sales with the two fastest-growing rivals; Rank stores by sales change to see whether the store gap is broad or concentrated.

A strong candidate

Separated company from industry and located the fixable part.

A weak candidate

Blamed "the difficult industry" and missed that most of the loss was specific to the company.

Worked case

Managing a declining business for cash

The prompt

A UK printed-directory business has revenue of GBP 50 million a year, falling about 10 percent a year as the whole industry moves online. Its fixed costs are GBP 20 million a year, and its variable costs are 40 percent of revenue. How long does it stay profitable, and what should the owner do?

Candidate-led: you choose what to model and propose the options; the interviewer challenges your conclusions.

Open this case to practice it with a partner

Clarifying questions, with the interviewer's answers

  1. Is there any sign the decline will slow?Answer: No, the whole industry has declined at a similar rate for years.
  2. What does the owner want?Answer: The most cash over the remaining life of the business.

A hypothesis to say out loud: This is an industry problem, not a company problem, so my hypothesis is that the right answer is to manage the decline for cash, not to promise growth.

The structure

  • Profit path as revenue falls, and the optionsThis comes from profit = revenue minus variable costs minus fixed costs, with revenue falling about 10 percent a year.
    • Profit now and next year
    • Key: Break-even revenue and when it is reached
    • Harvest by cutting fixed costs; consolidate; exit

Working it through

  1. 1. Profit now

    Candidate: "I will model profit as revenue falls, starting from today." Revenue minus variable costs minus fixed costs, in GBP millions.

    Profit now (GBP m):50 - 50 × 0.4 - 20 = 10
  2. 2. Profit next year

    Revenue falls 10 percent to 45; fixed costs stay at 20. Interviewer: "Why does profit fall so much faster than revenue?" Candidate: "Because the GBP 20 million of fixed cost does not shrink, so profit falls 30 percent while revenue falls 10 percent."

    Profit next year (GBP m):45 - 45 × 0.4 - 20 = 7
  3. 3. Break-even revenue

    Fixed costs divided by (1 minus the 40 percent variable share).

    Break-even revenue (GBP m):20 ÷ (1 - 0.4) = 33.33
  4. 4. Revenue in four years

    Four years of 10 percent decline takes revenue just below break-even. Interviewer: "The owner wants a digital relaunch to grow again." Candidate: "The whole industry is moving online, and rivals online are far ahead, so I would not bet the remaining cash on growth. I would rather make the decline pay."

    Revenue in 4 years (GBP m):50 × 0.9 × 0.9 × 0.9 × 0.9 = 32.81
  5. 5. Harvest: cut fixed costs

    Candidate: "How much fixed cost could we remove?" Interviewer: "Fewer offices and outsourced printing could bring it to GBP 15 million." That lowers break-even revenue.

    New break-even revenue (GBP m):15 ÷ (1 - 0.4) = 25

The recommendation

Manage the decline for cash rather than chase growth. First, at current costs, profit falls from GBP 10 million to GBP 7 million next year, because fixed costs do not shrink with revenue. Second, revenue drops below the break-even of about GBP 33 million in about four years. Third, cutting fixed costs as revenue falls, for example to GBP 15 million, lowers break-even revenue to GBP 25 million and adds years of profit. Stop new investment in print, consider buying a rival to share fixed costs, and plan an orderly sale or exit before losses begin.

Risks: The decline may speed up; Deep cuts may damage service to the remaining customers.

Next steps: Build a three-year plan to reduce fixed costs; Approach likely buyers or rivals about a combination.

A strong candidate

Recognized an industry decline, modeled how fixed costs speed up the fall in profit, and chose harvest with a clear exit plan.

A weak candidate

Proposed a new marketing campaign to grow printed directories against a declining industry.

Prompt: "Our sales are falling; the industry is tough."

Weaker answer

Accepts the industry excuse and recommends only general cost cuts, or promises growth in a declining industry.

Stronger answer

Compares company decline with industry decline. If most of it is share loss, treats it as a fixable company problem; if the whole industry is declining, models break-even and plans a harvest or exit.

Why the stronger answer wins: The strong answer locates the cause and matches the answer to it. The weak one gives the same answer to two very different problems.

Common mistakes, traps, and curveballs

  • Promising growth in a declining industry
  • Treating an industry problem as a company problem, or the reverse
  • Cutting so deep the business cannot recover
  • Refusing to consider exit when it is the right call
How firms often vary on this type

Restructuring and turnaround practices push hardest here. Expect to be asked when exit is the right answer, which tests judgment over optimism. Formats differ by office and change over time, so check the current process for your target office.
