Imagine you open the financial statement of a huge company and see something that doesn't seem to make sense.
The company has tens of billions of dollars in cash.
Then you discover it has also borrowed tens of billions of dollars.
Your first reaction is probably:
“Wait… if the company already has billions in the bank, why is it borrowing money?”
It sounds completely backwards.
If you have $50,000 in your bank account, you probably wouldn't take out a $30,000 personal loan just because you felt like it.
So why do companies do something similar on a much larger scale?
The answer is that cash and debt can serve different purposes.
A company may borrow money while holding substantial cash because it wants to preserve liquidity, fund a huge investment program, take advantage of attractive borrowing conditions, avoid disturbing money committed to other purposes, finance acquisitions, return capital to shareholders, or simply maintain a financial cushion.
In other words:
Having cash doesn't mean all of that cash is available to spend.
And even when it is available, management may decide that borrowing is the better financial decision.
This is one of those corporate-finance decisions that looks irrational until you understand how companies think about money.
The Simple Example
Imagine a company has:
$20 billion in cash
It wants to build a new factory costing:
$5 billion
You might assume the company should simply pay the $5 billion from its bank account.
But management could instead issue:
$5 billion of bonds
and keep the $20 billion in cash.
Why?
Because that cash may have other jobs.
The company may need it for:
Daily operations
Future acquisitions
Research and development
Share buybacks
Dividends
Unexpected expenses
Debt repayments
A recession
Supply-chain problems
Future investment
So the company isn't necessarily saying:
"We don't have money."
It may be saying:
"We don't want to use this particular money for this particular purpose."
That's a very different decision.
Cash Is Not Just Money Sitting in a Vault
When you see:
Cash and cash equivalents: $50 billion
it's tempting to imagine $50 billion sitting in a giant warehouse somewhere.
That's not how corporate cash management works.
Cash can include:
Bank deposits
Treasury bills
Money-market instruments
Highly liquid short-term investments
and other cash-equivalent assets.
Companies may intentionally hold these assets because they provide liquidity and capital preservation.
Microsoft, for example, reported $76.8 billion in cash, cash equivalents and short-term investments at June 30, 2026. The company said those resources were intended in part to facilitate liquidity and capital preservation, while also stating that it expected continued access to debt markets. (sec.gov)
That tells us something important.
Cash has a job.
Why Wouldn't Microsoft Simply Spend Its Cash?
Microsoft's June 2026 filing provides a useful real-world example.
The company reported:
$76.8 billion in cash, cash equivalents and short-term investments.
But it also reported substantial capital spending, including a $51.4 billion increase in additions to property and equipment during fiscal 2026. Microsoft also said it issues debt to take advantage of favorable pricing and liquidity in debt markets, with proceeds potentially used for working capital, capital expenditures, acquisitions, share repurchases, and repayment of existing debt. (sec.gov)
Think about what this means.
A company can have:
Cash
and
large investment needs
at the same time.
Using debt allows management to fund those investments without necessarily drawing its entire cash reserve down.
Cash Gives a Company Flexibility
Imagine you're running a company during an uncertain period.
You have:
$20 billion in cash
and:
$10 billion of planned investment.
You could spend the entire $10 billion immediately.
Or you could borrow some of the money and preserve more cash.
Why might you prefer the second option?
Because the future is uncertain.
Perhaps an acquisition opportunity appears.
Maybe a recession begins.
Maybe a competitor suddenly becomes available for purchase.
Perhaps a major supplier fails.
Maybe raw-material prices surge.
Perhaps a new technology requires an enormous investment.
Cash gives management options.
And options are valuable in business.
The SEC has previously noted that firms may hold cash to prepare for transactions such as acquisitions or stock repurchases, while financially strong companies can simultaneously raise debt in capital markets. (sec.gov)
A Company Doesn't Want to Be Cash-Rich Today and Cash-Poor Tomorrow
This is another reason companies may borrow.
Imagine a business spends almost all of its cash building new factories.
Then, six months later, demand collapses.
The company now has:
Huge factories
but
very little liquidity.
That can create a serious problem.
Management might therefore decide:
"We can afford to fund this investment with debt while keeping a substantial cash reserve."
It's a form of financial insurance.
The company pays interest to keep access to capital while preserving liquidity for unexpected events.
Debt Can Be Used to Match Long-Term Investments
Suppose a company is building a facility expected to generate revenue for:
20 years.
It might make sense to finance part of that facility with long-term debt.
Why?
Because the asset will generate economic benefits over many years.
Instead of paying the entire cost today, the company spreads the financing over time.
This concept is sometimes called matching the financing duration to the asset's useful life.
The idea is straightforward:
Long-lived assets can be financed with appropriately structured long-term funding.
That can reduce pressure on the company's current cash balance.
Borrowing Can Also Preserve Liquidity During Rapid Growth
Imagine a company is growing extremely quickly.
Sales are rising.
It needs:
More factories
More employees
More inventory
More data centers
More equipment
More warehouses
Growth itself can consume cash.
A company may therefore borrow even while it is profitable.
Why?
Because the money is being invested back into the business faster than profits are becoming available for every project.
This is especially common in capital-intensive industries.
The Difference Between Profit and Cash
This is one of the most important concepts in corporate finance.
A company can be profitable without generating the same amount of cash immediately.
Why?
Accounting profit and cash flow aren't identical.
A company can recognize revenue under accounting rules before collecting all the cash.
It can make large investments.
It can have non-cash expenses.
It can have changes in working capital.
So management pays close attention to:
Net income
and
operating cash flow
and
free cash flow
They tell different parts of the story.
What Is Free Cash Flow?
Free cash flow is commonly used as a measure of how much cash a business generates after the spending required to maintain or expand its productive assets.
A simplified version is:
Free cash flow ≈ Operating cash flow − Capital expenditures
It's not a perfect universal definition because companies and analysts can calculate related measures differently.
But the basic idea is useful.
Suppose a company generates:
$15 billion operating cash flow
and spends:
$10 billion on capital expenditures.
It has roughly:
$5 billion
of free cash flow before other considerations.
That $5 billion can potentially be used for:
Debt repayment
Dividends
Share buybacks
Acquisitions
Cash reserves
or additional investments.
Why a Company Might Borrow Even While Generating Billions in Free Cash Flow
Imagine your business generates:
$10 billion of annual free cash flow
but management wants to invest:
$20 billion
this year.
The company has choices.
It can:
Spend its existing cash
Borrow $10 billion
Issue shares
or
use a combination.
Borrowing may be attractive if management believes the investment will generate enough future returns to justify the financing cost.
This is essentially the corporate version of:
"Should I use my savings or borrow to fund a productive investment?"
The answer depends on the cost of borrowing, expected returns, liquidity needs, risk and strategic priorities.
Debt Isn't Automatically Bad
People sometimes hear:
"The company has $50 billion of debt."
and immediately think:
"That's terrible."
Not necessarily.
Debt can be extremely useful.
Imagine a company can borrow:
$10 billion at 4%
and invest that money in a project expected to produce returns substantially above the cost of financing.
The debt could help accelerate growth.
But the calculation is never guaranteed.
The project could fail.
Interest rates could rise.
Revenue could disappoint.
The company may have difficulty refinancing the debt.
So debt can amplify both opportunity and risk.
The Real Question Is: How Much Does the Debt Cost?
Suppose a company has:
$30 billion of debt
at an average interest rate of:
3%
Its annual interest expense would be roughly:
$900 million
Now imagine another company has:
$30 billion of debt
at:
8%
The annual interest burden would be roughly:
$2.4 billion
Same amount of debt.
Completely different financial burden.
That's why investors look at:
Interest expense
Average borrowing rate
Debt maturity
Cash flow
Credit rating
Debt-to-EBITDA
and other measures.
The amount of debt alone doesn't tell you enough.
Why Companies Sometimes Borrow When Interest Rates Are Low
This one is fairly intuitive.
If a company can lock in a long-term borrowing rate that management considers attractive, it may choose to raise debt even if it already has significant cash.
The company may believe:
"We'd rather pay a manageable financing cost and preserve our cash."
This can be especially appealing if management expects future capital requirements to be large.
But "cheap" is relative.
A 4% borrowing cost could be attractive to one company and expensive to another depending on its expected returns, credit quality and alternatives.
Why Companies Borrow When Interest Rates Are High
This is more interesting.
Sometimes they borrow because they have to.
A company may have debt maturing.
It needs to refinance.
Or it may have a major project that management believes cannot wait.
Other times, the company may be protecting its cash position because uncertainty is high.
The decision therefore isn't simply:
"Are rates high?"
It's:
"What is the opportunity cost of using our cash instead?"
Opportunity Cost Is the Hidden Answer
Suppose a company has:
$10 billion in cash
It can use the money to pay for a project.
But suppose that same cash could support:
an acquisition
that management expects to create substantial value.
Or perhaps it wants to maintain enough liquidity to survive an unexpected downturn.
The cost of using cash isn't simply zero.
There is an opportunity cost.
By spending cash today, the company gives up the opportunity to use that cash somewhere else.
Debt can therefore preserve flexibility.
Why Companies Keep Cash and Debt at the Same Time
Imagine a company has:
$50 billion cash
and:
$50 billion debt.
At first glance, that looks ridiculous.
But suppose:
$50 billion of debt matures gradually over 10 years
while the company generates:
$15 billion of annual operating cash flow.
The company may be managing its balance sheet deliberately.
Also, some cash may be held in different jurisdictions, committed to particular purposes, or needed for operations.
And debt may have been issued at favorable rates while the cash provides flexibility.
This is why sophisticated financial analysis looks at net debt, not just gross debt.
What Is Net Debt?
A simplified calculation is:
Net debt = Total debt − Cash and cash equivalents
Suppose:
Debt = $50 billion
Cash = $30 billion
Net debt:
$20 billion
That's a very different picture from simply saying:
"The company has $50 billion of debt."
Net debt isn't the only measure investors should use, but it provides useful context.
Apple's Balance Sheet Shows the Idea
Apple is another good example.
As of June 27, 2026, Apple reported approximately:
$82.3 billion of fixed-rate notes
while its broader liquidity resources included cash, cash equivalents and marketable securities.
Apple's filing said it expected its cash, marketable securities, operating cash generation, and continued access to debt markets to be sufficient to meet its cash requirements and capital-return program. (sec.gov)
Apple also reported $61.8 billion of share repurchases during the first nine months of fiscal 2026. (sec.gov)
That illustrates an important point:
A company can simultaneously:
Hold cash
Have debt
Invest heavily
and
return money to shareholders.
Corporate capital allocation isn't a simple "cash first, debt second" sequence.
Why Companies Borrow to Buy Back Their Own Shares
This is one of the more controversial uses of corporate debt.
Suppose a company has:
$20 billion in cash
and wants to return:
$10 billion
to shareholders through buybacks.
It could use cash.
But management might instead borrow part of the money.
Why?
Potentially because it wants to:
Maintain liquidity
Keep cash available for operations
Fund another investment
Take advantage of financing conditions
There can also be tax considerations depending on the country and corporate structure.
But this strategy creates additional risk.
The company is replacing some equity funding with debt.
If future cash flow weakens, the debt still has to be serviced.
This is why investors need to examine the whole capital structure, not simply whether a company announced a buyback.
Why Companies Borrow to Make Acquisitions
Imagine a company sees a competitor it wants to acquire.
The deal costs:
$20 billion.
The company has:
$30 billion cash.
Why not simply pay cash?
It might.
But perhaps management wants to retain:
$20 billion of liquidity
after the deal.
It could use:
$10 billion cash
plus
$10 billion debt
instead.
Now the company still has a substantial cash cushion.
The acquisition is funded.
The company has added leverage.
Again, it's a trade-off.
Why Companies Borrow to Build AI Infrastructure
This has become especially important.
Large technology companies are investing heavily in:
Data centers
AI servers
Networking
Power infrastructure
Land
Energy capacity
The upfront capital requirements can be enormous.
Microsoft's 2026 filing, for example, reported a major increase in property-and-equipment spending and said its debt proceeds can be used for capital expenditures and other corporate purposes. (sec.gov)
A company doesn't necessarily want to fund every dollar of a multi-year infrastructure buildout from existing cash.
Debt allows it to spread the financing burden across time.
What If the Company Has More Cash Than Debt?
This is where the concept of net cash becomes useful.
Imagine:
Cash = $40 billion
Debt = $25 billion
The company has:
$15 billion net cash
Yet it might still issue another:
$5 billion debt
That can still make sense.
Why?
Because management may not want to reduce its cash buffer.
The company may also have:
Future investments
Debt maturities
Acquisition opportunities
Shareholder distributions
Working-capital requirements
Cash is a strategic resource.
Is Cash Always Available to Spend?
Not necessarily.
A company's cash may be:
Held overseas
Needed for operations
Committed to contracts
Invested in short-term securities
Needed for upcoming debt repayments
Reserved for acquisitions
or otherwise subject to practical or legal constraints.
For example, Apple reported substantial manufacturing and other purchase obligations in its 2026 filings. As of June 27, 2026, it reported $57.0 billion of manufacturing purchase obligations, with most due within 12 months. (sec.gov)
That gives you an idea of why a large cash balance doesn't mean every dollar is "extra."
Companies have future commitments.
Why Companies Like Having Access to Credit Even When They Don't Need It Today
Imagine you have a credit card with a large available limit.
You don't need to use it.
But you're more comfortable knowing it's there for an emergency.
Companies think similarly.
A company may maintain:
Revolving credit facilities
Commercial paper programs
Bond-market access
Bank relationships
even if it has plenty of cash today.
That financial access can become extremely valuable during a crisis.
Why Borrowing Can Become More Expensive During a Crisis
This is why companies sometimes raise debt before they desperately need it.
Imagine the economy is healthy.
Credit markets are open.
Investors are willing to buy corporate bonds.
A company can borrow at:
4%
Then imagine a financial crisis occurs.
Investors become nervous.
The same company might have to borrow at:
7%
or perhaps much more.
So management may decide to raise funding while conditions are favorable and hold the proceeds as liquidity.
It's not necessarily a sign that the company expects disaster.
It can be risk management.
Why Credit Ratings Matter
Companies with stronger balance sheets and credit profiles generally have better access to financing than weaker businesses, all else equal.
Credit-rating agencies assess factors such as:
Leverage
Cash flow
Debt-service capacity
Business risk
Liquidity
Industry conditions
A high-quality borrower may be able to issue bonds at a lower rate.
A financially stressed company may have to pay much more.
This is one reason large, established companies can sometimes borrow relatively cheaply while smaller or highly leveraged companies face much greater financing costs.
Why Debt Can Actually Increase a Company's Return on Equity
Here's a more advanced concept.
Suppose a company earns:
$10 billion
of profit.
It has:
$100 billion
of shareholder equity.
Its return on equity is roughly:
10%
Now suppose it uses debt to finance some of its operations or repurchase some shares.
If profits remain strong while equity becomes smaller, the return on equity can increase.
This is known as financial leverage.
But there is an important catch.
Leverage works both ways.
If profits fall sharply, the same debt can make the company's financial position much more difficult.
That's why investors shouldn't automatically celebrate a rising return on equity caused by increased leverage.
They need to ask:
"Where did the higher return come from?"
Why Debt Can Make a Good Company Stronger—and a Weak Company Weaker
Imagine two businesses.
Company A
Strong cash flow
Low debt
Predictable revenue
Strong competitive position
Company B
Weak cash flow
High debt
Unpredictable revenue
Low margins
A small amount of additional borrowing could be manageable for Company A.
The same debt could be dangerous for Company B.
That's why corporate debt has to be considered relative to:
Cash flow
Profitability
Interest expense
Assets
Debt maturity
Business stability
A $10 billion debt balance doesn't mean much by itself.
What Happens If a Company Can't Refinance?
This is one of the biggest risks.
Suppose a company has:
$5 billion debt
maturing next year.
It doesn't have enough cash to repay it.
Normally, it may simply issue new debt and use the proceeds to repay the old debt.
That's called refinancing.
But what if credit markets are closed?
Or investors demand extremely high interest rates?
The company could face a serious liquidity problem.
That's why the maturity schedule of debt matters.
Short-Term Debt Can Be More Dangerous
Imagine a company has:
$20 billion in debt
but:
$15 billion matures within 12 months.
That's potentially much more stressful than having the same $20 billion spread over 20 years.
A company may generate enough cash to handle the debt.
But it still needs to ensure that sufficient liquidity is available when maturities arrive.
This is why investors read the debt-maturity table rather than stopping at the total debt figure.
Why Companies Sometimes Issue Debt to Repay Older Debt
This sounds pointless:
"Why borrow money just to pay back money you already borrowed?"
Because the new debt may have:
A lower interest rate
A longer maturity
Better terms
Better flexibility
or
A different currency
Imagine a company has debt costing:
7%
maturing soon.
It may issue new debt at:
5%
and use the proceeds to repay the old debt.
The total debt may remain similar.
But the company's financing cost or maturity profile can improve.
This is called refinancing.
Why Companies Borrow in Different Currencies
Multinational companies operate around the world.
They may earn revenue in:
Dollars
Euros
Pounds
Yen
and other currencies.
They may also have expenses and assets in several countries.
Issuing debt in a particular currency can sometimes help match financing with the company's cash flows or assets.
But currency borrowing introduces its own risks.
If revenues are in one currency and debt is in another, exchange-rate movements can change the real burden of the debt.
Why Companies Keep Cash Even When Cash Earns Interest
Some people think:
"Why not just borrow less and use cash?"
Because the company has to compare the return on keeping cash with the cost of borrowing.
Suppose:
Cash earns 4%
while
debt costs 5%.
Using cash to repay the debt could make obvious sense—assuming the cash is genuinely excess and other considerations don't outweigh that benefit.
But suppose:
Cash earns 4.5%
and
debt costs 4.5%.
The decision becomes more complicated.
And suppose management values the liquidity enormously.
The company might choose to keep the cash despite the small difference.
Corporate finance is about trade-offs.
Taxes Can Influence the Decision Too
In some tax systems, interest payments on qualifying corporate debt can be deductible, subject to applicable rules and limitations.
That can make debt financing more attractive than it appears from the stated interest rate alone.
But tax treatment varies significantly by:
Country
Company structure
Type of debt
Tax rules
and
Regulatory conditions.
So investors shouldn't assume that debt is automatically "cheap" because interest may be deductible.
Why Cash and Debt Can Coexist for Rational Reasons
Let's put the pieces together.
A company might have:
$30 billion cash
and
$20 billion debt
because it wants to:
Fund growth
Maintain liquidity
Prepare for acquisitions
Finance capital expenditure
Refinance existing debt
Return money to shareholders
Protect itself from economic shocks
Take advantage of capital-market conditions
None of those automatically means management is making a mistake.
The key question is whether the overall capital structure makes economic sense.
What Investors Should Look At
When you see a company with lots of cash and lots of debt, don't immediately assume something is wrong.
Start with these questions.
How much cash does the company have?
Look at cash and cash equivalents, plus relevant short-term investments.
How much debt does it have?
Don't look only at gross debt.
What is its net debt?
Compare debt with cash.
When does the debt mature?
A large near-term maturity can create refinancing risk.
What interest rate is the company paying?
Debt cost matters.
How much cash flow does the business generate?
Strong recurring cash flow can support debt.
What is management doing with the borrowed money?
Investment?
Acquisitions?
Buybacks?
Refinancing?
Is the investment producing returns?
This is perhaps the most important question.
A Simple Example
Imagine a company has:
$40 billion cash
$20 billion debt
$15 billion annual operating cash flow
Management decides to invest:
$10 billion
in a new business.
It could spend cash.
Instead, it raises:
$5 billion debt
and spends:
$5 billion cash.
Afterward:
Cash = $35 billion
Debt = $25 billion
The company has increased its leverage.
But it has also preserved a large liquidity reserve.
Whether this was a good decision depends on:
The debt cost
The project's expected return
The company's future cash flow
The risk of the investment
Its other financial commitments
That's the real analysis.
What Happens When Companies Borrow Too Much?
This is where the strategy can go wrong.
Imagine a company keeps borrowing.
Then:
Interest expenses rise
↓
Cash flow becomes more constrained
↓
Debt maturities approach
↓
Refinancing becomes more expensive
↓
Investors become nervous
↓
The stock price falls
↓
Creditors demand even higher rates
This can create a vicious cycle.
That's why leverage can be powerful but dangerous.
Why Companies With Huge Cash Reserves Still Go Bankrupt
This sounds almost impossible.
But it can happen if:
Debt is too large
Cash is insufficient relative to short-term obligations
Assets lose value
Cash flow collapses
Credit markets close
or
large liabilities suddenly come due
A company may look rich based on its assets and still face a liquidity crisis.
This is similar to the banking concept we discussed in our article:
Why Can a Bank Fail If It Has Billions of Dollars in Assets?
The underlying principle is similar:
Asset value and available liquidity are not the same thing.
The Difference Between Being Rich and Being Liquid
Imagine you own:
A $1 million house
A $200,000 business
$100,000 of investments
but only:
$5,000 cash
You might be wealthy.
But you're not necessarily liquid.
A company faces the same distinction.
It can own valuable:
Factories
Patents
Inventory
Real estate
Long-term investments
while still needing cash for immediate obligations.
That's why financial statements need to be read as a system rather than a collection of isolated numbers.
Why Companies Don't Always Pay Down Debt as Fast as Possible
You might think:
"If a company has extra cash, shouldn't it pay off all its debt?"
Sometimes.
But debt can provide useful financing.
A company may prefer to:
Maintain liquidity
Invest in growth
Fund acquisitions
Buy back shares
Pay dividends
instead of eliminating every dollar of debt.
The right amount of debt depends on the business.
A stable company with predictable cash flow may reasonably carry more debt than a highly cyclical business.
The Bigger Picture
The question:
“Why does a company borrow money when it already has cash?”
has a surprisingly simple answer:
Because cash and debt are tools, not opposites.
Cash provides:
Liquidity
Flexibility
Security
Optionality
Debt can provide:
Capital
Leverage
Long-term financing
Flexibility in capital allocation
A company may deliberately use both.
Microsoft's 2026 filing is a good example. It reported $76.8 billion in cash, cash equivalents and short-term investments, yet also said it issues debt to take advantage of favorable pricing and liquidity in debt markets, with debt proceeds available for purposes including capital expenditures, acquisitions, share repurchases and refinancing. (sec.gov)
Apple provides another example, reporting billions in cash and marketable securities while maintaining significant debt and continuing substantial capital returns to shareholders. (sec.gov)
The lesson isn't:
“Companies should borrow even when they have cash.”
Nor is it:
“Companies should never borrow if they have cash.”
The answer depends on the economics.
What does the debt cost?
What will the company do with the money?
How much liquidity does management want?
When does the debt mature?
How predictable is cash flow?
What return is expected on the investment?
And perhaps the most important question:
Would using the company's cash today leave it less capable of handling tomorrow?
That's why a company can rationally sit on billions of dollars while simultaneously issuing billions in debt.
From the outside, it can look contradictory.
From inside a corporate-finance department, it's often a question of timing, risk, flexibility and opportunity cost.
And that is something ordinary investors can use when reading a company's financial statements.
Don't just ask:
“How much cash does this company have?”
Ask:
“Why is it holding that cash?”
And don't just ask:
“How much debt does it have?”
Ask:
“What is the debt paying for, how expensive is it, and can the company comfortably carry it?”
Those questions tell you much more about a company's financial health than either number alone.
