Quarterly, Annual, and TTM Financial Data: What Is the Difference?
Quarterly data covers a company’s results for roughly three months, annual data covers a full fiscal year, and trailing-twelve-month data combines the latest.

Quarterly data covers a company’s results for roughly three months, annual data covers a full fiscal year, and trailing-twelve-month data combines the latest four quarters. Quarterly data is timely but often seasonal and volatile. Annual data is more complete but less current. TTM data provides a recent full-year view, although it may combine periods reported under changing conditions.
Key Takeaways#
- Quarterly results are useful for detecting recent changes.
- Annual statements provide a fuller view and are generally audited in public-company filings.
- TTM data combines the most recent four quarters rather than one fiscal year.
- Seasonality can make quarter-to-quarter comparisons misleading.
- Investors should keep numerator and denominator periods consistent when calculating ratios.

What Is Quarterly Data?#
Quarterly data reports performance for an interim period, usually about three months. In the United States, many public companies provide Form 10-Q reports for their first three fiscal quarters and a Form 10-K for the full year. The SEC notes that these filings describe operating and financial results for the relevant quarter or fiscal year.
Quarterly information helps investors identify changes in demand, pricing, expenses, cash flow, and management guidance. However, one quarter can be distorted by seasonality, timing, weather, launches, one-time costs, or customer concentration.
What Is Annual Data?#
Annual data covers the company’s fiscal year. A full-year filing generally contains audited financial statements, extensive notes, risk factors, management discussion, and business descriptions.
Annual data smooths some quarterly volatility and provides a better basis for evaluating full-cycle margins, taxes, and capital allocation. Its disadvantage is timing: by the time an annual report is published, conditions may already have changed.
A company’s fiscal year does not need to match the calendar year. Retailers, for example, may use a year ending after the holiday season. Investors should verify exact period dates before comparing companies.
What Is TTM Data?#
Trailing-twelve-month, or TTM, data represents the latest twelve months available. For income-statement and cash-flow items, it is commonly calculated by adding the latest four quarters.
TTM Revenue = Revenue in Latest Four Quarters
Suppose quarterly revenue is $100 million, $120 million, $140 million, and $160 million. TTM revenue is $520 million.
When a new quarter is reported, the oldest quarter drops out and the newest quarter is added. This makes TTM data more current than the last fiscal year while retaining a full-year period.
Flow Items vs Point-in-Time Items#
Revenue, expenses, net income, and cash flows are flow measures covering a period. They can be summed across quarters.
Cash, debt, inventory, receivables, and equity are balance-sheet amounts measured at a date. Investors should not add four quarterly cash balances. Ratios combining flow and stock measures often use average balance-sheet values.
For example:
Return on Assets = TTM Net Income / Average Total Assets
Average assets may be approximated using beginning and ending balances, although more frequent averages can improve accuracy.
Quarter-over-Quarter vs Year-over-Year#
Quarter-over-quarter growth compares the latest quarter with the immediately preceding quarter. It can reveal acceleration but is vulnerable to seasonality.
Year-over-year growth compares a quarter with the same quarter one year earlier. This is often more informative for seasonal businesses.
A retailer’s fourth quarter may always be much larger than its third quarter. Comparing Q4 with Q3 could exaggerate growth, while comparing Q4 with the prior-year Q4 better controls for the holiday cycle.
TTM vs Fiscal-Year Data#
TTM and annual data are identical only immediately after a fiscal year ends and before another quarter is reported. After the first new quarter, TTM includes three quarters from the prior fiscal year and one from the new year.
TTM can be distorted when the company changes accounting presentation, completes a major acquisition, sells a division, or has unusual events. Pro forma analysis may be required to make periods economically comparable.
Common Mistakes#
One mistake is combining a TTM numerator with a single-quarter denominator without annualizing or averaging appropriately. Another is comparing companies using different period ends without recognizing seasonality.
Investors should also avoid annualizing one exceptional quarter by multiplying it by four. A quarter affected by a shortage, tax benefit, or product launch may not represent a sustainable run rate.
The Quantiverse Perspective#
Quantiverse uses multiple time frames because each answers a different question. Recent quarters reveal direction and inflection. TTM data provides a current full-year base. Multi-year history shows durability and cyclicality. A signal becomes more reliable when short-term improvement is consistent with cash generation, balance-sheet movement, and a plausible position in the business cycle.

Is TTM data audited?
The annual portion is based on audited statements, but interim quarters are generally reviewed rather than audited to the same extent. TTM is an analytical combination, not a separate audited reporting period.
Can TTM EPS be calculated by adding quarterly EPS?
Adding reported quarterly EPS may differ slightly from annual EPS because weighted-average shares and dilution are calculated separately. Using TTM net income and an appropriate share count is often more consistent.
Should investors use quarterly or annual margins?
Use both. Quarterly margins show recent change; annual or TTM margins reduce seasonality and one-quarter noise.
