Rhea-AI Filing Summary

Colliers International Group Inc. (CIGI) is the issuer named in an amended ownership report by Spruce House Investment Management LLC, Spruce House Capital LLC, The Spruce House Partnership LLC, Zachary Sternberg, and Benjamin Stein. The three Spruce entities and Sternberg, manager of the first two, each report beneficial ownership of 3,235,000 subordinate voting shares, with shared voting and dispositive power, or approximately 6.5% of the class.

Stein, a member of the issuer’s board, reports 3,282,012 shares, approximately 6.6%, including direct beneficial ownership of 47,012 shares. The reported percentages use 49,778,127 shares outstanding as of August 5, 2026. The reporting persons disclaim beneficial ownership except to the extent of their pecuniary interests.

Filing Explained

Stein's reported 47,012-share beneficial position includes 24,187 shares issuable under options exercisable now or within 60 days; it excludes 9,563 options not exercisable within 60 days and 3,960 vested DSUs payable in cash after board service, so the reported total is not solely shares already held outright.

beneficial ownership regulatory
"may be deemed the beneficial owner of the 3,235,000 Shares"
Beneficial ownership means the person or entity that actually enjoys the benefits of owning shares or other assets — such as receiving dividends, voting rights, or price gains — even if the legal title is held in another name. For investors it matters because knowing who truly controls and profits from a company reveals who can influence decisions, exposes potential conflicts of interest or hidden concentration of power, and affects transparency and risk in the stock.
shared voting power regulatory
"Shared Voting Power 3,235,000.00"
Shared voting power occurs when two or more parties jointly have the right to vote or decide how a block of company shares is cast, like co-owners who must agree before moving a piece of furniture. Investors care because who controls voting rights affects board elections, major corporate decisions and takeover outcomes, and shared control can alter regulatory disclosures and the practical influence any holder has over a company’s direction and value.
Rule 13d-3 regulatory
"for purposes of Rule 13d-3 under the Act"
Rule 13d-3 defines who is treated as the beneficial owner of a company’s shares for U.S. securities disclosure rules — essentially anyone who has the power to vote or direct how shares are voted, or the power to buy or sell them, even if they don’t hold the certificates. For investors this matters because crossing certain ownership thresholds triggers public filing and disclosure obligations and signals potential control or influence, much like having the keys to a car implies you can drive it even if it’s registered to someone else.
deferred share units financial
"3,960 deferred share units ("DSUs") granted as director compensation"
Deferred share units are promises that give an executive or director the right to receive company shares or their cash value at a future date, often when they retire or leave the company. Think of them as a paycheck held in a savings account that converts into stock later; they matter to investors because they tie pay to long-term performance, create potential future dilution of shares, and represent a delayed cash or share obligation the company must eventually fulfill.
underwritten public offering financial
"165,200 Shares were purchased in an underwritten public offering"
An underwritten public offering is when a company sells new shares of its stock to the public with the help of a financial firm, called an underwriter. The underwriter agrees to buy all the shares upfront, reducing the company's risk, and then sells them to investors. This process helps companies raise money quickly and confidently from a wide range of buyers.
margin loans financial
"may, at any given time, include margin loans"
Margin loans are loans from a brokerage that let an investor borrow money using their existing stocks, bonds or cash as collateral to buy more securities. They matter because borrowing magnifies both gains and losses—like using a lever to move a heavier load—so small market moves can have outsized effects on your returns; investors also pay interest and risk a margin call, where the broker may force sales if collateral falls below required levels.
