FMP has added diluted price-to-earnings and price/earnings-to-growth fields to its Financial Ratios APIs. Released on July 30, 2026, the additions provide P/E and PEG measures calculated on a fully diluted earnings-per-share basis. They are available through both the Financial Ratios API and the Financial Ratios TTM API.
New Fields in Ratios and Ratios TTM
The field names identify both the valuation measure and its diluted earnings basis:
|

Diluted PEG |

|
Financial Ratios TTM |
Diluted P/E, trailing twelve months |
priceToEarningsDilutedRatioTTM |
|
Financial Ratios TTM |
Diluted PEG, trailing twelve months |
priceToEarningsDilutedGrowthRatioTTM |
The TTM endpoint uses the corresponding fields with a TTM suffix. This gives developers an explicit mapping when incorporating the measures into applications, spreadsheets, or valuation tables.
Make the Earnings Basis Visible
The earnings basis is an important part of interpreting a valuation ratio. A table that labels every measure simply as “P/E” can obscure which earnings definition underlies each value. The new fields allow users to select and label the diluted measures directly.
For analysts, that supports more deliberate comparisons between companies and datasets. For developers, it provides clearly named fields to map into interfaces and calculations. Carrying those distinctions into display labels helps users understand which metric they are reviewing.
The July 30 financial ratios release note documents all four additions. Users can review their existing ratio mappings and add the diluted fields where that earnings basis fits their analysis.
