## Geographic presence

Constellation Software reported 2025 revenue of $11.623 billion across four geographic categories: the United States, $4.837 billion (41.6%); UK/Europe, $4.069 billion (35.0%); Canada, $1.052 billion (9.1%); and Other, $1.665 billion (14.3%). Percentages are calculated from reported revenue. The company classifies revenue by where it is transacted and its intellectual property is located, which may differ from the customer’s location. [14](https://app.finbar.com/go?id=T15807182)

At December 31, 2025, non-current assets were reported as $4.349 billion in UK/Europe, $3.900 billion in the United States, $1.414 billion in Other, and $705 million in Canada. The company is domiciled in Canada and lists its registered office in Toronto, Ontario. Its website describes a customer reach of more than 150,000 customers in over 160 countries; this indicates international reach but does not provide a country-level sales or employee distribution. [14](https://app.finbar.com/go?id=T15807182)[15](https://app.finbar.com/go?id=P138326288)[6](https://www.csisoftware.com/)

## Business segments

Constellation Software groups its vertical-market software businesses into six operating groups: Volaris, Harris, Topicus, Vela, Jonas and Perseus. For financial reporting, however, the company aggregates these groups into a single IFRS 8 reportable segment; it does not disclose separate revenue or operating income for each group. [16](https://app.finbar.com/go?id=P138325602)[17](https://app.finbar.com/go?id=P138325606)

The groups focus on software for specific industries and business processes. Volaris’ portfolio includes agri-food, asset management, supply chain, justice, rental management, education and retail; Harris includes utilities, local government, education and healthcare; and Jonas includes fitness, leisure, sports-club management, food and beverage, and hotels and resorts. [18](https://www.volarisgroup.com/about/)[19](https://www.harriscomputer.com/news/harris-year-in-review-looking-back-on-2025)[20](https://jonassoftware.com/our-companies) Vela’s portfolio spans areas including automotive, construction, government, healthcare, logistics and travel; Perseus includes vertical software for homebuilding, manufacturing and dealerships. Topicus is described as a diversified vertical-market software provider. [21](https://velasoftwaregroup.com/portfolio/)[22](https://csiperseus.com/about/)[23](https://app.finbar.com/go?id=P138358531)

The company does not report revenue shares for the six operating groups, so their individual contributions cannot be estimated from its segment disclosures. As a separate, non-equivalent supplemental breakdown for FY2025, CSI excluding Topicus and Lumine accounted for approximately 78.4% of consolidated revenue, Topicus 15.0%, and Lumine 6.6%; these figures are not a six-group segment allocation.

## Company history

Constellation Software was incorporated in Ontario on August 23, 1995, and began acquiring vertical-market software businesses that year, starting with Trapeze Group. [25](https://www.csisoftware.com/wp-content/uploads/2026/04/2024-Annual-Information-Form-Final.pdf)[4](https://www.csisoftware.com/constellation-software-inc-announces-the-resignation-of-mark-leonard-and-appointment-of-mark-miller-as-president-of-constellation-software/) It completed its initial public offering on May 18, 2006, and continued to grow through acquisitions. [25](https://www.csisoftware.com/wp-content/uploads/2026/04/2024-Annual-Information-Form-Final.pdf)

The company expanded its international operations through the Topicus business; its history includes an initial acquisition in 2014, followed by Topicus’s spin-out as a public company in 2021. [26](https://app.finbar.com/go?id=P138325176)[27](https://www.csisoftware.com/constellation-software-inc-completes-spin-out-of-topicus-com-inc/) In 2023, Constellation completed the spin-out of Lumine Group as a separate public company. [28](https://www.csisoftware.com/constellation-software-inc-and-lumine-group-inc-complete-purchase-of-wideorbit-inc-and-lumine-group-spin-out/) In September 2025, founder Mark Leonard resigned as president and the board appointed COO Mark Miller to the role; Leonard remained a director.
