15-Step Approach
Let's use our 15-step approach to analyze the company.
At the end of this article, we'll give Microsoft a score on each of these 15 metrics.
This results in a Total Quality Score.
1. Do I understand the business model?
Microsoft is a leading technology company that develops, licenses, and supports software products, services, and devices.
Founded in 1975 by Bill Gates and Paul Allen, Microsoft has grown into one of the world's most well-known and valuable companies.
Gates wanted to build a platform like no other:
"A platform is when the economic value of everybody that uses it, exceeds the value of the company that creates it." - Bill Gates
Microsoft is active in three main markets:
Productivity and Business Processes (42.6% of total revenue): This includes sales of Microsoft Office software, such as Word and Excel, and subscription services like Microsoft 365. It also covers business tools like LinkedIn and Dynamics 365
Intelligent Cloud (39.4% of total revenue): Microsoft makes money from its Azure cloud services, which provide computing power, storage, and other services to businesses
More Personal Computing (18.0% of total revenue): This segment includes revenue from Windows operating system licenses for PCs, sales of Surface tablets and laptops, and Xbox gaming consoles. It also covers advertising and search revenue from Bing
So next time you're working on a document or playing a game, remember Microsoft is behind the scenes making it all happen.
As you can see in the chart below, half of Microsoft's revenue comes from the US.

Please note that by investing in Microsoft, you are also investing ChatGPT.
Microsoft currently owns 27% of OpenAI.
2. Is management capable?
Satya Nadella is the CEO of Microsoft since 2014.
Nadella joined the company in 1992, leading major projects on building and running cloud computing and development.
It's great seeing Nadella must own a minimum of 15x his base salary worth of Microsoft stocks.
In 2013, Amy Hood became the CFO. She joined Microsoft in 2002 after finishing her MBA at Harvard University.
Insider ownership is less than 1% (total value: $1.1 billion).
What's great seeing? Employees would recommend working at Microsoft (high Glassdoor rating).
3. Does the company have a sustainable competitive advantage?
Microsoft is a global leader with a wide moat.
Their competitive advantage is based on high switching costs.
Users and businesses find it costly and difficult to move away from its integrated software and services. This dependency keeps customers loyal to Microsoft.
Microsoft also benefits from other moat sources:
Intellectual property: Microsoft holds numerous patents and copyrights
Brand strength: Microsoft has a well-known brand name and strong reputation
Economies of scale: They produce software and services more efficiently
Network effects: Windows and Office increase in value as more people use it because of compatibility
Barriers to entry: Microsoft's compliance with global regulations creates high barriers to entry
Companies with a sustainable advantage have these qualities:
Gross Margin: 68.6% (Gross Margin > 40%? YES)
Return On Invested Capital (ROIC): 22.0% (ROIC > 15% YES)
Microsoft is investing heavily in AI.
That's the main reason why you see a declining ROIC.
We think this number will go up again over time as these investments will yield a return eventually.

4. Is the company active in an attractive end market?
Microsoft is active in attractive end markets for sure.
Here are just a few examples:
Windows is a clear market leader in the Personal Computing Market. They have a 75% market share with Apple as a major competitor
The company's Cloud Services segment is active in a competitive market. Microsoft has a 20% market share in this segment. This market is expected to grow at a CAGR of 16.0% until 2033. Main competitors are Amazon, Google Cloud, Alibaba Cloud and IBM.
Market leader in the productivity software market (Office, LinkedIn, ..). Google is a major competitor in this segment.

5. What are the main risks for the company?
Here are some of the main risks for Microsoft:
Intense competition: A lot of competition from other Big Tech companies
Data security risks: Microsoft is a prime target for cyberattacks and breaches that could damage its reputation
Rapid advancements in technology (AI): While Microsoft has made major bets on AI through its OpenAI partnership, the pace of innovation means it risks being disrupted
Regulations: Growing scrutiny from regulators across the US and Europe around antitrust, data privacy, and AI governance
High valuation levels (see later)
6. Does the company have a healthy balance sheet?
We look at 3 ratios to determine the healthiness of Microsoft's balance sheet:
Interest Coverage: 53.2x (Interest Coverage > 15x? YES)
Net Debt/FCF: Net Cash Position (Net Debt/FCF < 4x? YES)
Goodwill/Assets: 18.0% (Goodwill/assets not too large? < 20% YES)
Microsoft's balance sheet looks healthy.

7. Does the company need a lot of capital to operate?
We prefer to invest in companies with CAPEX/Sales lower than 5% and CAPEX/Operating Cash Flow lower than 25%.
Microsoft:
CAPEX/Sales: 27.2% (CAPEX/Sales < 5%? NO)
CAPEX/Operating Cash Flow: 51.8% (CAPEX/Operating CF? < 25% NO)
But wait… Microsoft is investing heavily in future growth.
Remember that there is a difference between Maintenance CAPEX and Growth CAPEX.
Maintenance CAPEX: Investments made in existing assets
Growth CAPEX: Investments made in new assets in order to grow
When a company invests a lot in order to grow, its growth CAPEX is very high but these investments might create a lot of value in the long term.
That's why sometimes (like for Microsoft) it might make sense to only take the company's Maintenance CAPEX into account.
As a rule of thumb, we state that the company's maintenance CAPEX is equal to the company's Depreciation & Amortization.
When we only take Microsoft's Maintenance CAPEX (without R&D costs) into account, we get the following:
CAPEX/Sales: 2.8% (CAPEX/Sales < 5%? YES)
CAPEX/Operating Cash Flow: 5.3% (CAPEX/Operating CF? < 25% YES)
These numbers already look way more attractive.

8. Is the company a great capital allocator?
Capital allocation is the most important task of management.
Look for companies that put the money of shareholders to work at attractive rates of return.
Microsoft:
Return On Equity: 34.4% (ROE > 20%? YES)
Return On Invested Capital: 22.0% (ROIC > 15%? YES)
These numbers look attractive.

9. How profitable is the company?
The higher the profitability of the company, the better.
Here's what things look like for Microsoft:
Gross Margin: 68.6% (Gross Margin > 40%? YES)
Net Profit Margin: 39.0% (Net Profit Margin > 10%? YES)
Average FCF/Net Income past 5 years: 80.4% (FCF/Net Income > 80%? YES)
Microsoft's is a very profitable company.

10. Does the company use a lot of Stock-Based Compensation?
Stock-based compensation is a cost for shareholders and should be treated accordingly.
Preferably we want SBCs as a % of Net Income to be lower than 4% and certainly below 10%.
Microsoft:
SBCs as a % of Net Income: 10.3% (SBCs/Net Income < 10%? NO)
Avg. SBC as a % of Net Income past 5 years: 11.3% (SBCs/Net Income < 10%? NO)
As you can see, Microsoft uses quite some Stock-Based Compensation.
This is a cost for shareholders like us. We will take this into our valuation models (see later).

11. Did the company grow at attractive rates in the past?
We look for companies that managed to grow their revenue and EPS by at least 5% and 7% per year respectively.
Microsoft:
Revenue Growth past 5 years (CAGR): 14.8% (Revenue growth > 5%? YES)
Revenue Growth past 10 years (CAGR): 13.2% (Revenue growth > 5%? YES)
EPS Growth past 5 years (CAGR): 19.0% (EPS growth > 7%? YES)
EPS Growth past 10 years (CAGR): 27.2% (EPS growth > 7%? YES)
These growth figures look attractive.
Source: Fiscal.ai
12. Does the future look bright?
You want to invest in companies that manage to grow at attractive rates as stock prices tend to follow FCF per share growth over time.
Microsoft:
Exp. Revenue Growth next 2 years (CAGR): 15.9% (Revenue growth > 5%? YES)
Exp. EPS Growth next 2 years (CAGR): 18.0% (EPS growth > 7%? YES)
EPS Long-Term Growth Estimate: 13.5% (EPS growth > 7%? YES)
This outlook looks attractive.
13. Does the company trade at a fair valuation level?
Now let's dive into the valuation.
It's very important as even the best company in the world can be a horrible investment if you pay too much for it.
We always use 3 methods to look at the valuation of a company:
A comparison of the forward PE multiple with its historical average
Earnings Growth Model
Reverse Discounted-Cash Flow
A comparison of the multiple with the historical average
The first thing we do is compare the current forward PE with its historical average.
Today, Microsoft trades at a forward PE of 22.8x versus a historical average of 27.8x over the past 10 years.

Earnings Growth Model
This model shows you the yearly return you can expect as an investor.
In theory, it's easy to calculate your expected return:
Expected return = EPS growth + Dividend Yield +/- Multiple Expansion (Contraction)
Here are the assumptions I use:
EPS Growth = 12% per year over the next 10 years
Dividend Yield = 0.9%
Forward PE to decline from 22.8 to 20.0x over the next 10 years
Expected yearly return = 12% + 0.9% - 0.1* ((20.0-22.8)/22.8)) = 11.7%
An expected yearly return of 11.7% looks attractive.
Reverse DCF
Charlie Munger once said that if you want to find the solution to a complex problem, you should invert. Always invert. Turn the problem upside down.
A reverse DCF shows you the expectations implied in the current stock price.
You try to determine for yourself whether these expectations are realistic or not.
The estimated Free Cash Flow for Microsoft next year is $80.6 billion.
We also subtract the Stock-Based Compensation ($12.3 billion) and add Growth CAPEX ($40.9 billion) to arrive at FCF in year 1 of $109.2 billion.
Under these assumptions, our Reverse DCF indicates that Microsoft should grow its Free Cash Flow by 12.8% per year to return 10% per year to shareholders.
A growth rate of 12.8% is possible but ambitious if you ask me.
Forward PE: 22.8x (lower than its 10-year average? < 27.8x? YES)
Earnings Growth Model: 11.7% (Yearly return? > 10%? YES)
Reverse DCF: 12.8% (Realistic growth expectations? UNCERTAIN)
14. How did the Owner's Earnings of the company evolve in the past?
Over time, stock prices tend to follow the Owner's Earnings of a company (EPS Growth + Dividend Yield).
That's why we want to invest in companies that managed to grow their Owner's Earnings at attractive rates in the past. This is the case for Microsoft.
Microsoft:
CAGR Owner's Earnings (5 years): 19.9% (CAGR Owner's Earnings > 12%? YES)
CAGR Owner's Earnings (10 years): 28.1% (CAGR Owner's Earnings > 12%? YES)
15. Did the company create a lot of shareholder value in the past?
We want to invest in companies that managed to compound at attractive rates in the past.
Ideally, the company returned more than 12% per year to shareholders since its IPO.
Here's what the performance of Microsoft looks like:
YTD: -17.1%
5-year CAGR: +12.5%
CAGR since 2001: +13.6% (CAGR since IPO > 12%? YES)
