How to separate organic growth from acquisition growth with public signals

A jump in a company's headcount or in its technology footprint has two possible causes: the company hired and built, or it bought another company. This guide shows how to separate organic growth from acquisition growth with public signals, so that a financial analysis of scale does not read a purchase as momentum. It gives four tests, a table of how each signal reads either way, what the SEC's rules and staff say about measures a company defines itself, and a worked example.

How do you separate organic growth from acquisition growth with public signals?

To separate organic growth from acquisition growth, run four tests on dated public signals. Find the company's announcement of an acquisition and its date. Check whether the count rose in a step or along a slope. Look for new websites and brands under the parent. For a listed company, read what its filings say about the acquired business.

On this page organic growth means growth from the business a company already owned. Acquisition growth, also called inorganic growth, means growth that arrives with a business it bought. In a total the two look the same. They differ in shape and in the record around them.

1. The announcement and its date. Look for an announcement on both sides, the buyer's and the bought company's. A listed buyer in the United States may also report the deal to the SEC on a Form 8-K: the staff's interpretations of that form, last updated on 24 June 2024, treat entry into a material definitive agreement (Item 1.01) and completion of an acquisition or disposition of assets (Item 2.01) as separate items. Keep both dates, and set the change in a count against the completion.
2. A step or a slope. Hiring adds roles a few at a time, so a count that grows that way rises along a slope. A purchase adds a whole business on one date, and the count rises in a step.
3. New websites and brands under the parent. A bought business that keeps its website and job board appears as a new brand or subsidiary of the parent. Its records are the acquired part, and the parent's own records stay comparable with their past.
4. What the filings say. A listed company explains its revenue in its annual report, and a significant purchase brings filings of its own, read in the next section.

No single row settles the question. An announcement with no step can be a small purchase, and a step with no announcement can be a website or a job board observed for the first time.

Organic growth vs acquisition revenue: the definition of organic growth in a public company 10-K

Organic growth is a measure each company defines for itself. We found no definition of it in the SEC staff's interpretations on non-GAAP financial measures or in the non-GAAP topic of the staff's Financial Reporting Manual. In a 10-K, read the company's own definition: which acquired revenue it leaves out, for how long, and at which exchange rates.

Two voices speak for the regulator. The Commission makes the rules, among them Regulation G and Items 10(e) and 303 of Regulation S-K, and issues interpretive guidance. The staff of the Division of Corporation Finance publishes interpretations on non-GAAP financial measures, last updated on 13 December 2022, and a Financial Reporting Manual, last revised on 29 June 2026, whose Topic 8 covers non-GAAP measures.

The manual describes a non-GAAP financial measure as a numerical measure of a registrant's historical or future financial performance, financial position or cash flow that leaves out amounts included in the most directly comparable GAAP measure, or takes in amounts which that measure leaves out. Its common examples include adjusted revenues and measures presented on a constant-currency basis. For a measure of that kind, Item 10(e) of Regulation S-K requires four things in a filing: the most directly comparable GAAP measure with equal or greater prominence; a reconciliation of the differences between the two, quantitative for a historical measure; a statement of why management believes the measure gives investors useful information; and, to the extent material, the other purposes management uses it for.

A growth figure can also be a metric. In an interpretive release issued on 30 January 2020, the Commission gave guidance on key performance indicators and metrics in management's discussion and analysis, with same store sales among its examples. It would generally expect a metric to come with a clear definition and how it is calculated, the reasons it is useful to investors, and how management uses it. Where the method changes from one period to another, a company should consider disclosing, to the extent material, the differences, the reasons and the effects.

Where one company's organic growth figure sits within these texts depends on how that company builds and presents it. Either way the definition is in the filing.

Organic vs inorganic growth disclosure: the revenue reconciliation in a 10-K

A 10-K can separate organic from inorganic growth in two places. Management's discussion and analysis explains material changes in revenue, as Item 303 of Regulation S-K requires. Where a company presents organic growth as a non-GAAP measure, the reconciliation that Item 10(e) requires is the bridge from reported revenue to the organic figure.

The SEC's guide to reading a 10-K places the description of the business, including the subsidiaries the company owns, in Item 1, management's discussion and analysis in Item 7, and the audited financial statements with their notes in Item 8. Item 303 of Regulation S-K sets what the discussion covers. Where the financial statements show material changes from period to period in a line item, the company describes the underlying reasons in quantitative and qualitative terms. For a material change in net sales or revenue, it describes how far the change comes from prices, from the volume or amount of goods or services sold, or from the introduction of new products or services.

Read a reconciliation as a sum. Reported growth equals organic growth, plus the contribution of acquisitions, less that of disposals, plus the effect of exchange rates, each as the company defines it. If the parts fall short of the reported figure, the definition holds a term you have yet to find.

Organic growth, acquisitions and constant currency revenue disclosures in a company annual report

A company annual report can state revenue growth as reported, at constant currency and on an organic basis. SEC staff answered on 11 January 2010 that a constant currency presentation is a non-GAAP measure. For a significant acquired business, SEC rules generally require its pre-acquisition financial statements and pro forma financial information, which size the acquired part.

The constant currency answer is Question 104.06 of the staff's interpretations. It adds that a company may meet the reconciliation requirements by presenting the historical amounts beside the constant currency amounts and describing how the latter were calculated and the basis of presentation.

On acquisitions, the Commission's press release of 21 May 2020 summarises the rules and the amendments it had voted to adopt. Rule 3-05 of Regulation S-X generally requires a registrant that acquires a significant business to provide that business's separate audited annual and unaudited interim pre-acquisition financial statements, and Article 11 requires unaudited pro forma financial information relating to the acquisition or disposition. The amendments limit those statements to no more than the two most recent fiscal years.

For issuers in the European Union, the European Securities and Markets Authority published guidelines on alternative performance measures on 5 October 2015. They cover a financial measure of past or future performance, financial position or cash flows other than one defined or specified in the applicable financial reporting framework, and they apply to measures disclosed on or after 3 July 2016.

Running the four tests on dated company signals

Fokals delivers the records behind the first three tests for listed companies worldwide, the brands they own and verified private companies. Every record carries the time it was observed.

• Company News. Company announcements and regulatory disclosures classified into 13 event types, two of which are an acquisition made and acquired or merged. Each row has the date the company published it, or the time it was first observed where the announcement carries no date, and the address of the original.
• Employee Headcount. Stated headcount over time, each count with the date it refers to.
• Hiring Activity. Open, new and closed postings for each company and closed day, written once and never revised.
• Technology Stack and Technology Changes. The technologies on each company website with their first-seen and last-seen dates, and a dated event for every adoption and removal.

Each company has one stable company ID, and a brand or subsidiary carries the identifiers of its listed parent, so grouping by ISIN gives the group while the company ID keeps each business apart, as the note on the identifiers that make company data joinable sets out. A first observation sets a baseline and is never counted as a change, which is how each table is written: a website or a job board that is new to the record brings its present state and no burst of activity.

The queries are PostgreSQL over the datasets loaded from bulk files, with list columns loaded as jsonb. A name that starts with a colon is a parameter you set, every date included. The first query stores the companies that carry the parent's ISIN, and the second lists their announcements of either event type in a window.

create table group_companies as
select distinct company_id, company
from company_technologies
where isin = :parent_isin;

select n."at", n.company, n.event_types, n.title, n.url
from company_news n
join group_companies g on g.company_id = n.company_id
where n."at" >= :window_start
  and n."at" <  :window_end
  and (n.event_types @> '["acquisition_made"]'
    or n.event_types @> '["acquired_or_merged"]')
order by n."at";

The third query sets the listed company's open postings beside the whole group's, day by day, with postings opened less postings closed across the group.

select h.day,
       sum(h.open_postings) filter (
         where h.company_id = :parent_company_id)    as parent_open,
       sum(h.open_postings)                          as group_open,
       sum(h.new_postings) - sum(h.closed_postings)  as opened_less_closed
from company_hiring_daily h
join group_companies g on g.company_id = h.company_id
where h.day >= :window_start
  and h.day <  :window_end
group by h.day
order by h.day;

Read the parent's line as the organic one for as long as the bought business keeps its own job board. Count the bought business into the group from the completion date, and label its count on that date as acquired. What it adds after that date is organic to the group. On a fixed set of companies a day's change in open postings is close to postings opened less postings closed. A jump beyond that marks postings observed for the first time, a baseline that belongs to neither kind of growth.

The fourth query compares two stated headcounts with the postings the company opened between them. Employee Headcount has one row for each company, date and source, so the query keeps to one source, a value the data dictionary lists.

select
  (select employees from company_headcounts
    where company_id = :company_id and source = :source
      and as_of = :later_as_of)
  -
  (select employees from company_headcounts
    where company_id = :company_id and source = :source
      and as_of = :earlier_as_of)         as headcount_change,
  (select sum(new_postings) from company_hiring_daily
    where company_id = :company_id
      and day >  :earlier_as_of
      and day <= :later_as_of)            as postings_opened;

A posting records an intention to hire, so postings opened measure pace. A headcount change several times the postings opened is the mismatch that sends you back to the announcements. The data dictionary defines every field these queries read, and the announcements and scale and hiring pages describe the datasets.

Worked example: Acme Robotics buys a business in mid-year

Acme Robotics is an invented listed company, and every figure in this example is illustrative.

Assumptions:

• Reported revenue rose from 800 million to 1,000 million US dollars between two fiscal years. The company's reconciliation attributes 120 million of the later year to a business bought during it, and states that exchange rates reduced reported revenue by 16 million.
• Stated headcount rose from 4,000 to 5,200 between the two year ends. The completion announcement states that the bought business employs 900 people. Acme Robotics opened 380 postings between the year ends.
• On the day before completion Acme Robotics had 62 open postings and the bought business 33. Ninety days later they had 70 and 37.
• On the day before completion the websites of Acme Robotics carried 48 website and technology pairs, and the two websites of the bought business carried 21. Over the next ninety days Technology Changes shows 4 additions and 2 removals on the first set and 1 addition on the second.

The working:

• Revenue: 200 ÷ 800 = 25.0% reported. The acquired part is 120 ÷ 800 = 15.0%, and currency is −16 ÷ 800 = −2.0%. Organic growth is 25.0 − 15.0 + 2.0 = 12.0%, which checks against 1,000 − 120 + 16 = 896 and 896 ÷ 800 = 1.12.
• Headcount: 5,200 − 4,000 = 1,200, of which 900 came with the purchase and 300 did not. Against 4,000 that is 22.5% and 7.5%. The 380 postings opened sit near the 300 and far from the 1,200.
• Open postings: the group was Acme Robotics alone before completion, at 62, and both businesses after it, at 70 + 37 = 107. Of the change of 45, the 33 open at the bought business the day before completion are acquired. The other 12 are organic: 8 at Acme Robotics and 4 at the bought business since completion.
• Technology: 48 + 4 − 2 = 50 and 21 + 1 = 22 make 72. Of the change of 24, the 21 pairs present the day before completion are acquired and 3 are organic.

Read as one number, headcount grew 30.0%. Read with the announcement, three quarters of the increase, 900 of 1,200, arrived on one date, and the business itself grew 7.5%. The 300 also holds anyone who joined or left the bought business between the announcement and the year end, so read it as approximate. For a private company the first three tests carry the whole reading.
