⚡ Claude’s Take

This block is the author’s own independent opinion and general information only — not investment advice. The body of this article (Sections 1–15) is deliberately position-free and carries no price target; only this fenced block takes a view.

Verdict: BUY / accumulate-on-weakness. A genuine ~15–17% per-share compounder de-rated from ~26× to ~13× forward adjusted earnings on a Q1 that the tape mistook for a “miss.” Attractive accumulation zone ~$85–$105 (~12–15× forward Adjusted EPS of ~$7.5, and the bear-to-base of a defensible sum-of-the-parts); fair value ~$120–$150. At ~$97 the stock is paying you the bear case.

Tag: “Buy the asset manager, get the brokerage and the engineer for free.”

The single most important fact in this file: a defensible sum-of-the-parts puts Harrison Street — Colliers’ ~$108B-AUM, ~43%-net-margin real-asset investment manager — at roughly $3.2–4.3B of enterprise value, i.e. ~65–85% of Colliers’ entire ~$4.95B market capitalization. Buy CIGI here and the alt manager nearly covers the whole equity check; the #3–4 global commercial-real-estate-services platform and a fast-growing, WSP-style engineering roll-up come close to free. That is the mispricing. It exists because (a) Colliers is filed under a “Real Estate” label and gets sold every time rates twitch and CRE sentiment sours, (b) its GAAP earnings are genuinely ugly — FY2025 GAAP diluted EPS was $2.02 versus $6.58 adjusted, the gap dominated by a $1.25/share non-cash “non-controlling-interest redemption increment” that screens as a 48× P/E and scares off quant filters, and © the spring-2026 risk-off in cyclical/real-estate names hit a stock that had run to 26× into early 2026. Meanwhile the business compounded Adjusted EPS +14% in 2025, reaffirmed mid-teens 2026 growth, grew capital-markets revenue +43% in Q1’26 off a cyclical trough, and converted 105% of adjusted earnings to free cash. A respected concentrated value fund, Spruce House, filed a 13D at 5.04% into the drawdown — they see the same thing.

I will not oversell it, and this is a BUY rather than a table-pound for four honest reasons. (1) The model has real frictions: the “partnership” structure leaves $1.285B of redeemable non-controlling interests on the balance sheet — equity puts Colliers must eventually buy from operating partners in cash or stock — a genuine claim senior to common that I deduct in full in my SOTP, and the recurring source of the GAAP-vs-adjusted gap. (2) Leverage is rising at the wrong-feeling moment: the ~US$700M, ~11× EBITDA, debt-funded Ayesa engineering acquisition pushes net-debt/EBITDA from 2.0× toward ~3× pro forma in 2H’26. (3) Brokerage is still a cyclical, weak-moat, people business whose recovery is hostage to rates. (4) Founder control: Jay Hennick holds ~41.6% of the vote on ~14% of the economics via 20-vote multiple-voting shares — though, crucially, this is a self-extinguishing overhang, contractually collapsing 1-for-1 with no premium by no later than September 1, 2028. The single piece of evidence that flips me decisively more bullish: two more quarters of capital-markets re-acceleration plus Investment Management organic fee growth turning convincingly positive (FY2025 IM fees were flat ex-catch-up — the central bear datapoint). The single piece that flips me bearish: a renewed rate spike that stalls the CRE recovery while leverage sits at ~3× and Ayesa integration slips. Conviction: medium-high. Framing: value/contrarian on a quality compounder caught in a de-rating — best expressed by accumulating into weakness, not chasing a bounce.

1. Executive Summary

Colliers International Group is a global, diversified professional-services and investment-management company built and chaired by founder Jay S. Hennick, run through three segments across the “built environment”: Commercial Real Estate (FY2025 revenue $3.29B, 59% of total — investment-sales/capital markets, leasing, and a large recurring “outsourcing” book of property/facilities management, valuation & advisory, and mortgage servicing); Engineering & Project Management (FY2025 revenue $1.73B, 31% — infrastructure, transportation, water, environmental and buildings consulting, assembled rapidly via acquisition); and Investment Management (FY2025 revenue $532M, 10% — the Harrison Street-branded real-asset alternative manager, $108.2B AUM, ~43% net margin). Colliers was created in June 2015 when the predecessor FirstService split into two public companies — Colliers (CIGI) and FirstService (FSV) — both founded by Hennick. Where FirstService kept property services, Colliers kept the Colliers brokerage brand and has since deliberately rebuilt itself away from pure cyclical brokerage toward recurring, scalable, higher-value professional services: management states >70% of earnings now come from recurring revenues.

The FY2025 print was strong on the metrics management runs the company by, and weak on GAAP optics. Revenue rose 15% to $5.56B, net revenue +14% to $4.87B, Adjusted EBITDA +14% to $732.5M, and Adjusted EPS +14% to $6.58; consolidated internal (organic) revenue growth was +5% in local currency, with the balance from acquisitions (chiefly Engineering). Free cash flow (company definition) was $352M, a 105% conversion of adjusted net earnings. But GAAP diluted EPS fell to $2.02 from $3.22, and the gap to the $6.58 adjusted figure — intangible amortization ($2.18/sh), the non-controlling-interest redemption increment ($1.25/sh), stock-based comp ($0.85), restructuring/integration ($0.50), and acquisition items ($0.16) — is wide and partly composed of real economic costs. The most distorting line, the NCI redemption increment, is the accretion on the $1.285B of redeemable minority equity created by Colliers’ partnership model.

The investment tension is straightforward. This is a business with a 31-year claimed track record of ~17% compound annual growth in per-share value, that doubled in size over the last five years (~15% revenue CAGR), guiding to mid-teens growth in revenue, EBITDA and Adjusted EPS in 2026 — yet the stock has de-rated from ~26× forward Adjusted EPS at its early-2026 high (~$171) to ~13× today (~$97), a ~43% drawdown. The proximate triggers were a Q1’26 report the market read as a soft “miss” (Adjusted EPS +5%, tempered by a one-off European tax-rate spike), a broad spring-2026 risk-off in rate-sensitive/cyclical names amid renewed geopolitical tension, and unease at the debt-funded Ayesa deal lifting leverage toward ~3×. Against its own ten-year history, CIGI now sits in the <1st percentile on price/book and ~1st percentile on price/sales — near the cheapest it has ever been on those measures.

This memo argues each verdict from the evidence. The body takes no position and sets no price target; the only view is the fenced Claude’s Take above. The throughline: Colliers is a good-and-improving business (a genuinely valuable alt manager and engineering franchise bolted onto a cyclical-but-recovering brokerage) priced as a distressed real-estate cyclical, with real frictions (the redeemable-NCI claim, rising leverage, founder control) that justify some discount but not a ~50% multiple compression on a mid-teens compounder.

2. Business Overview

2.1 What Colliers does

Colliers describes itself as operating “across the full asset lifecycle” of the built environment — find, finance, design, build, manage, and invest. In practice it is three quite different businesses sharing a brand, a culture, and a client base:

Commercial Real Estate (CRE) — FY2025 revenue $3,290.6M; net revenue $3,064.5M; Adjusted EBITDA $366.9M (12.0% net margin). This is the historic core — the Colliers brokerage franchise, the world’s #3–4 CRE-services platform behind CBRE and JLL and alongside Cushman & Wakefield. It comprises:

• Capital Markets (investment-sales brokerage and debt finance/mortgage banking) — the most cyclical, highest-incremental-margin line; revenue accelerated through 2025 (+16% FY2025, +43% in Q1’26) as the transaction recession thawed.
• Leasing (landlord/tenant representation) — moderately cyclical (+2% FY2025, against a strong prior comp; +9% Q1’26).
• Outsourcing & Advisory — the recurring layer: property and facilities management, project management, valuation & appraisal, loan servicing/mortgage servicing, and occupier services. This is contracted/repeatable revenue and is what lets management claim a high recurring-earnings mix even inside the “real estate services” label. Outsourcing grew +7% in FY2025, led by valuation & advisory.

Engineering & Project Management — FY2025 revenue $1,734.9M (+40%); net revenue $1,305.8M; Adjusted EBITDA $164.7M (+50%; 12.6% net margin). A multidisciplinary engineering-consulting business — infrastructure, transportation, water, environmental, buildings, telecom, program/project management — assembled largely by acquisition (notably Englobe in Canada and the just-closed Ayesa in Spain). Revenue is backlog-driven, recurring, and tied to public and private infrastructure spending, with strong end-market visibility. This is structurally the most attractive growth engine and the one re-shaping Colliers’ identity toward a WSP/Stantec-style consulting compounder.

Investment Management — FY2025 revenue $532.3M (+4%); net revenue $495.6M; Adjusted EBITDA $214.8M (+1%); 43.3% net margin; AUM $108.2B (+9% YoY). The crown jewel by quality — the Harrison Street-branded real-asset alternative manager (Colliers is consolidating four platforms, including infrastructure manager Basalt, under one Harrison Street Asset Management brand). Strategies concentrate on demographically- and secular-tailwind-driven real assets: data centers (Colliers owns ~64 data-center assets and has been in the space six years), senior housing, student housing, medical office, healthcare delivery, plus a smaller (~8–10% of AUM) real-estate-backed credit book. It earns management fees on committed/called capital plus performance fees — annuity-like, multi-year, high-margin revenue.

2.2 How it makes money & revenue quality

Consolidated FY2025 revenue of $5.56B is reported alongside a “net revenue” measure ($4.87B) that strips subconsultant/pass-through costs (large in Engineering and project management) and historical pass-through performance fees — a sensible cleanup that better reflects the economic top line. The earnings mix is deliberately barbelled: cyclical, high-operating-leverage transaction revenue (capital markets, leasing) on one side; recurring, contracted, high-margin revenue (outsourcing, engineering backlog, investment-management fees) on the other. Management’s stated >70% recurring-earnings mix is the entire strategic thesis — the post-2015 project to make Colliers less of a brokerage and more of a diversified, durable professional-services compounder.

The business is low capital intensity: FY2025 capex was just $78.7M (~1.4% of revenue), mostly IT and fleet. The headline profitability metric management uses is Adjusted EBITDA ($732.5M, 15.0% of net revenue) and Adjusted EPS ($6.58), both of which strip acquisition accounting, the NCI redemption increment, stock-based comp (including the CEO’s LTIP), and restructuring/integration costs (scrutinized in Sections 6 and 10).

2.3 The partnership model — why the share structure and the balance sheet look the way they do

Colliers (like FirstService) runs a “partnership” operating model: when it acquires or builds a business, local operating leaders typically retain a minority equity stake in that subsidiary, with put rights allowing them to sell their stake back to Colliers over time (priced off a formula, usually a multiple of the subsidiary’s earnings), settleable in cash or Colliers shares. This is the engine of Colliers’ “enterprising culture and meaningful inside ownership” — operators are owners — but it has two visible balance-sheet consequences that dominate the GAAP optics:

• Redeemable non-controlling interests (RNCI) of $1.285B at 12/31/25 — the carrying value of those puttable minority stakes, classed as mezzanine equity because Colliers may be obligated to buy them.
• A recurring “NCI redemption increment” ($63.6M in FY2025, $1.25/share after-tax) — the period change in the redemption value of those puts, which flows through net earnings attributable to the Company and crushes GAAP EPS even though it is non-cash.

Understanding this single mechanism explains ~80% of why Colliers’ GAAP earnings look so much worse than its adjusted earnings and its cash flow (Sections 6 and 10).

Verdict (Business Overview): A coherent three-engine model — a recovering, scale-advantaged cyclical brokerage; a fast-growing, structurally attractive engineering roll-up; and a genuinely high-quality real-asset alternative manager — unified by a founder-led partnership culture. The blended business is good and improving in quality, deliberately tilted toward recurring revenue. The complexity (three businesses, IFRS, the RNCI/partnership plumbing, founder supervote) is real and is part of why the market mis-weights the parts.

3. Industry Dynamics

Colliers spans three industries with very different structures; the blended exposure is above-average but not pristine, and — importantly — the two faster-growing engines (engineering, alt management) command higher market multiples than the brokerage label the stock is filed under.

3.1 Commercial Real Estate services — cyclical, scale-driven, recovering

The global CRE-services industry is large, consolidating, and bifurcated between cyclical and recurring lines. Transaction businesses (investment sales, leasing, debt brokerage) are highly rate-sensitive and deeply cyclical: global investment volume peaked at a record ~$1.3T in 2021, fell ~34% into the 2022 H2–2023 trough as rates spiked, then began recovering — roughly +13% in 2024 and ~+19% in 2025 (MSCI/CBRE/JLL data) to ~$850–900B, still ~30%+ below the 2021 peak. Colliers management calls the recovery “early-to-mid innings,” ~a couple of years from prior peak — consistent with the macro data and with capital-markets revenue +43% in Q1’26. The recurring lines (property/facilities management, valuation, loan servicing) are contracted and far steadier.

Competitive structure: a scale-tiered oligopoly at the top (CBRE ~$42B revenue, JLL ~$27B, Cushman & Wakefield ~$10B, Colliers ~$5.6B, Newmark ~$3.5B) over a long fragmented tail. Barriers to entry are moderate: brand, global account relationships, data, and route density matter, but the brokerage itself is a people business with portable talent and low client switching costs at the deal level. The durable moat sits in the recurring outsourcing/servicing book (scale economics + client captivity), not in transactional brokerage. Verdict: structurally average industry — a B/B–. Cyclically, however, the setup is favorable: capital is not flooding into brokerage, and the cycle is turning up off a multi-year trough, so trailing earnings understate mid-cycle power.

3.2 Engineering & infrastructure consulting — structurally attractive, but a hot M&A market

Engineering/infrastructure consulting is backlog-driven, recurring, and riding a multi-year tailwind (transportation, water, energy transition, grid, and data-center-adjacent infrastructure). Margins run low-to-mid-teens EBITDA; demand has strong visibility; and the moat is intangibles (credentials, regulatory qualification, framework/panel incumbency) plus local scale and sticky backlog. The industry is fragmented, supporting a long roll-up runway — which is exactly the WSP and Stantec playbook Colliers is copying. Verdict: structurally attractive — an A–/B+. The Marathon (capital-cycle) caution is explicit: capital is flooding into engineering consolidation and deal multiples are rising (Colliers paid ~11× EBITDA for Ayesa), so the risk is overpaying for growth even as secular demand extends the cycle. Tellingly, the best engineering roll-ups (WSP, Stantec) trade at ~14–15× EV/EBITDA, well above CRE brokerage — a direct argument that this segment should lift Colliers’ blended multiple, not depress it.

3.3 Investment management (real assets) — the best of the three

Real-asset alternative management is the highest-quality industry Colliers touches: multi-year locked fee streams on committed capital, ~40%+ margins, and powerful secular tailwinds in exactly the sub-sectors Harrison Street targets (data centers, demographic real assets). Listed alternative managers are valued on fee-related-earnings multiples (~15–25× EBITDA) or % of AUM (~5–15% for alternatives) — far above brokerage or engineering. The catch is fundraising cyclicality: capital-raising slowed industry-wide in 2023–24 and is recovering in 2025–26 (Colliers targets $6–9B of new commitments in 2026, having raised >$5B in 2025). Verdict: structurally excellent — an A. This is the segment whose quality the market most under-credits inside the CIGI wrapper.

3.4 Capital-cycle (Marathon) synthesis

Capital is not flooding into CRE brokerage (cycle turning up off a trough — favorable for Colliers); it is flooding into engineering consolidation (rising deal multiples — a discipline risk for Colliers-as-acquirer) and into data-center real estate (where Harrison Street is, helpfully, contemplating selling assets into the heat). The net read: the cycle is tailwind in two of three engines and a pricing-discipline test in the third.

Verdict (Industry Dynamics): One average-but-recovering industry (brokerage), one structurally attractive one (engineering), and one excellent one (alt management). On a sum-of-industries basis Colliers’ mix is better than its “real estate services” label implies — the crux of the valuation argument.

4. Competitive Position

4.1 The moat, segment by segment (Greenwald taxonomy)

A moat must be (a) nameable as a mechanism and (b) tied to a financial outcome that would deteriorate without it.

Commercial Real Estate — a modest, scale-and-captivity moat concentrated in the recurring book. In transactional brokerage the advantage is real but bounded: the Colliers brand, global corporate-account relationships, proprietary data/research, and local route density let it win mandates and recruit producers, but talent is portable and clients re-bid deals — pricing power is limited and the line is cyclical. The durable moat is in outsourcing/servicing: once Colliers manages a portfolio or services a loan book, scale economics (regional labor pools, systems, procurement) and switching costs (operational disruption, data migration) create captivity. The financial fingerprint: CRE Adjusted EBITDA margin expanded ~50bps in Q4’25 on operating leverage, and the segment held positive organic growth through the transaction recession on the recurring base. Mechanism: economies of scale + customer captivity, concentrated in recurring lines. Verdict: narrow, line-specific moat — not a wide brokerage moat.

Engineering — an intangibles-plus-scale moat, early but real. Engineering firms compete on credentials, regulatory qualification, framework/panel incumbency, and reputation — high-switching-cost, relationship-and-compliance-driven work — reinforced by local scale and multi-year backlog. Colliers’ segment is younger and lower-margin than WSP/Stantec (12.6% net EBITDA margin vs their mid-teens), so it has not yet earned their full multiple, but the moat mechanism is sound and the backlog is described as “stronger than ever.” Mechanism: intangibles + local scale + backlog stickiness. Verdict: genuine, widening moat — the segment to watch.

Investment Management (Harrison Street) — the widest moat. The advantage is locked, multi-year fee streams on committed capital, specialized sector expertise (two decades in demographic real assets and data centers, deep relationships with universities, hospitals, health systems), and a two-decade track record that compounds fundraising. The financial fingerprint is unambiguous: ~43% net margins, evidence of real pricing power and captive, sticky capital. Mechanism: customer captivity (committed capital) + intangibles (track record, sector expertise). Verdict: the durable, high-return core.

4.2 Versus competitors

Against CBRE/JLL/CWK/Newmark, Colliers is the #3–4 global platform — sub-scale to CBRE/JLL but with a deliberately higher-quality earnings mix (a bigger relative contribution from engineering and alt management than any pure broker). Against WSP/Stantec/AECOM, Colliers’ engineering arm is smaller and earlier but growing faster (+40% FY2025) and acquisitively. Against listed alt managers, Harrison Street is a credible, scaled (~$108B AUM), high-margin real-asset franchise. The competitive truth: Colliers is no one’s category leader, but it owns a above-average position in three industries simultaneously, two of which are structurally better than the brokerage that defines its stock-market identity.

Verdict (Competitive Position): A collection of modest-to-strong, mechanism-specific moats — narrow in brokerage, widening in engineering, wide in investment management — held together by a founder-owner culture. Durable advantage is real and concentrated in the recurring engines; the cyclical brokerage is the thinner-moat, lower-quality piece that nonetheless drives the headline sentiment.

5. Growth History and Forward Opportunities

5.1 The track record

Colliers’ growth algorithm is the FirstService-lineage formula: mid-single-digit organic growth + tuck-under and platform acquisitions + operating leverage = low-teens revenue growth and mid-teens per-share earnings growth, compounded over decades. Management cites a 31-year ~17% CAGR in per-share value and notes the company doubled in size over the past five years (~15% revenue CAGR) despite the rate shock and transaction recession. The verified recent record: revenue $4.82B (2024) → $5.56B (2025), +15%; Adjusted EPS $5.75 → $6.58, +14%. Growth has been a blend of organic and acquired, tilting heavily acquired in Engineering (the +40% FY2025 segment growth was mostly M&A) and more organic in CRE and IM.

5.2 Forward opportunities

• CRE capital-markets recovery. The largest near-term swing factor. Capital-markets revenue +43% in Q1’26, guided ~+25% for FY2026, off volumes still ~30% below the 2021 peak — a multi-year operating-leverage tailwind on the highest-incremental-margin line, with a bigger, more productive producer base than at the last peak.
• Engineering scale-up. Ayesa adds ~3,200 professionals across 21 countries (~$370M gross revenue) and “opens 4–5 major markets,” plus a pipeline of operators wanting to join as partners — a runway to a WSP/Stantec-scale consulting franchise, with cross-sell into CRE (land assembly, entitlement, project management).
• Investment Management fundraising and re-rating. $6–9B 2026 fundraising target, new infrastructure/data-center strategies, first closes in Basalt and a Harrison Street closed-end fund; the Harrison Street brand unification should lift IM net margin back toward the low-40s once integration costs roll off.
• Cross-segment synergy — the “find, finance, entitle, build, own” flywheel across CRE, Engineering and IM — real but unquantified.

5.3 The quality caveat

The honest blemish: Investment Management organic fees were essentially flat in FY2025 (segment net revenue +1%, Adjusted EBITDA +1%, lapping prior-year catch-up fees), and Q1’26 IM net margin fell to 37.4% on integration spend. The growth in IM is currently coming from acquisition and AUM mix, not yet from re-accelerating organic fees — the central bear datapoint and the thing the bull case most needs to see inflect.

Verdict (Growth): High-quality, durable growth — a proven multi-decade compounding formula, currently powered by a genuine cyclical tailwind (capital markets) plus acquisitive engineering scale-up — but with a real near-term question mark over Investment Management organic fee growth that keeps this from being unambiguously pristine.

6. Financial Quality

6.1 Revenue, margins, and the segment shape

FY2025 net revenue of $4.87B carried a 15.0% consolidated Adjusted EBITDA margin ($732.5M). Segment net margins: CRE 12.0% (operating-leverage-driven, rising with capital-markets mix), Engineering 12.6% (productivity-led, below WSP/Stantec mid-teens — room to improve), Investment Management 43.3% (annuity-quality, the margin anchor). The mix is improving as the higher-margin recurring engines grow.

6.2 The GAAP-to-adjusted gap — read it carefully

This is the heart of the quality question. FY2025 GAAP diluted EPS was $2.02; Adjusted EPS was $6.58. The bridge (after tax, per share):

How to weigh each: amortization of acquired intangibles ($2.18) is a real cost of an acquisitive model but non-cash and arguably add-back-able for a serial acquirer; the NCI redemption increment ($1.25) is non-cash but represents real value transferred to minority partners — not a clean add-back; SBC ($0.85) is a real, dilutive economic cost that should not be fully ignored; restructuring/integration ($0.50) is recurring for a perpetual acquirer and only partly “one-time.” A conservative “owner-earnings” figure that keeps SBC and the NCI increment as real costs sits meaningfully below $6.58 — call it ~$4.50–5.25 — i.e. ~18–22× on that basis, versus ~13× on the company’s adjusted figure. The truth is between the two; the cash flow adjudicates it.

6.3 Cash flow — the reassuring part

FY2025 operating cash flow was $330.1M and company-defined free cash flow $352.3M — a 105% conversion of adjusted net earnings, ~7% of market cap. Cash conversion that closely tracks adjusted earnings (Adjusted net earnings were $336M) is the strongest evidence that the adjusted figure, not the depressed GAAP figure, reflects the real economics — the GAAP “miss” is largely accounting, not cash. Two asterisks: FCF is struck before RNCI put purchases (~$44M of NCI buyouts plus $71M of NCI distributions in FY2025) and before the ~$700M debt funding of Ayesa, so cash available to common is below the headline 7%; and there was no buyback in 2025 — the FCF is being reinvested in M&A.

6.4 Balance sheet

Net debt of $1,426M against pro-forma Adjusted EBITDA = 2.0× at 12/31/25, rising to ~2.9–3.0× pro forma the Ayesa close before declining in 2H’26 on seasonality and EBITDA growth. That is moderate, not alarming, leverage for a recurring-revenue-heavy services business — but it is rising into a cyclical recovery rather than falling, and it removes balance-sheet slack. Goodwill and intangibles of $3.86B reflect the acquisitive model. The $1.285B redeemable NCI is the balance-sheet expression of the partnership puts (Section 2.3) and is the single most important non-debt claim ahead of common.

Verdict (Financial Quality): Economics do improve with scale and mix — margins are rising, cash conversion is excellent, capital intensity is trivial. The blemishes are honest and bounded: GAAP earnings are genuinely opaque (and the NCI increment and SBC are real costs, not pure noise), and leverage is rising at a cyclically sensitive moment. On cash, this is a higher-quality business than its GAAP P/E suggests.

7. Capital Allocation

7.1 The model and the record

Colliers is a serial, disciplined-most-of-the-time acquirer that buys majority stakes and leaves operators with puttable equity (the partnership model). Capital has gone primarily into acquisitions ($262M in FY2025; $517M in FY2024) — Harrison Street (2018, ~75%), Basalt (infrastructure), Englobe (engineering), and now Ayesa (~US$700M, ~11× 2026E EBITDA, debt-funded) — plus organic producer recruiting and IT/AI investment (a deepening Google cloud partnership). The dividend is token ($0.30/share, ~5% payout, ~0.3% yield) — Colliers is explicitly a reinvestment-compounder, not an income story. No material buybacks in 2025, and FY2024 actually issued $287M of subordinate voting shares — so per-share value creation depends on reinvestment returns exceeding cost of capital, not on shrinking the count.

7.2 Is it good capital allocation?

The 31-year ~17% per-share CAGR is the headline evidence that the reinvestment machine has historically worked — buying private services businesses at single-to-low-double-digit multiples, scaling them, and arbitraging the public multiple. The open question is the present: Ayesa at ~11× EBITDA, debt-funded into a hot engineering-M&A market that is itself inflating deal prices (the Marathon caution), is a richer entry multiple than Colliers’ historical tuck-unders, and it consumes the balance-sheet slack. Management is signaling a near-term pivot back to smaller tuck-ins “at reasonable prices” while leverage normalizes — a reasonable response. The absence of buybacks with the stock at a decade-cheap valuation is a mild negative: if management truly believes shares “trade well below intrinsic value” (Hennick’s words), the lack of repurchase is a missed signal — though it is defensible given the Ayesa funding and the ~3× leverage.

7.3 Incentive alignment

Post-2021, Hennick takes no long-term incentive arrangement, options, or equity-linked compensation under his management services agreement — a genuine cleanup of the prior, controversial LTIA (Section 8). The current CEO performance-based LTIP and management’s puttable subsidiary equity tie pay to per-share value creation and subsidiary-level earnings — broadly well-aligned, “operators are owners.” Insiders hold ~11–14% of the economics. The partnership puts are a double-edged sword: they align operators and fund growth, but they create the RNCI claim and the recurring dilution/cash drain when puts are exercised.

Verdict (Capital Allocation): Historically intelligent, presently on watch. The multi-decade compounding record is real and the incentive structure is cleaner post-2021. The cautions are the richer, leverage-funded Ayesa multiple, the hot engineering-M&A cycle, and the failure to buy back a decade-cheap stock. Net: a good allocator entering a more expensive M&A environment with less balance-sheet room.

8. Changes and Headwinds — Last Two Years

• The strategic re-branding into “three engines” (2024–2026). Colliers formally re-segmented from “Real Estate Services” to Commercial Real Estate / Engineering / Investment Management, recasting prior periods — an explicit signal that engineering and IM are now co-equal pillars, not appendages of brokerage.
• The engineering build-out — Englobe, multiple Quebec/Canada tuck-ins, and the transformational Ayesa acquisition (announced Feb 2026, ~US$700M, closed late May 2026) — took Engineering to ~31% of revenue and pushed leverage toward ~3×.
• Leadership moves (Q1’26): Elias Mulamoottil appointed CEO of Engineering; Christian Mayer named CEO of Commercial Real Estate in addition to his Global CFO role — a notable doubling-up worth monitoring for stretch.
• The 2021 governance settlement maturing toward 2028. The dual-class sunset clock (Section 4 of Claude’s Take; detail below) now sits ~27 months out — a defined, narrowing overhang.
• Spruce House 13D (April 2026) at 5.04% — a concentrated value fund accumulating into the drawdown.
• The de-rating itself (spring 2026): the ~43% drawdown from ~$171 to ~$90s on a Q1 read as a “miss” (a one-off European tax-rate spike tempered Adjusted EPS to +5%), a broad risk-off in rate-sensitive/cyclical names amid renewed geopolitical tension, and leverage unease — RSI fell below 30 (oversold) in May 2026.
• Headwinds: rate volatility threatening the capital-markets recovery; European/APAC slowing (North America carried Q1’26); a higher near-term tax rate; integration risk on Ayesa; flat IM organic fees.

Verdict (Changes/Headwinds): The strategic changes strengthen the long-term thesis (higher-quality, more-recurring mix; a defined governance sunset) while the near-term changes raise the risk profile (leverage, integration, management stretch, a hostile tape). The business is getting better; the stock got cheaper — the gap is the opportunity.

9. Risk Analysis (Risk Matrix)

The dominant risks are cyclical (rate-driven CRE relapse) and balance-sheet (leverage into the Ayesa close) — both bounded and self-correcting if the recovery holds — plus the structural RNCI claim that a careful analyst must net against equity value. There is no realistic catastrophic-loss scenario absent a severe, prolonged CRE depression coinciding with peak leverage.

Verdict (Risk): A moderate, cyclical-and-structural risk profile, not a fragile one. The risks justify a discount and a margin of safety; they do not threaten the going concern.

10. Valuation Discussion (Embedded Expectations)

No price target; no recommendation. This section frames embedded expectations and scenarios only.

10.1 Where the multiple sits

At ~$97.11, CIGI trades at ~13.0× FY2026E Adjusted EPS (~$7.5), ~14.8× FY2025 Adjusted EPS ($6.58), ~12.9× EV/EBITDA, and a ~7% FCF yield — versus ~26× forward Adjusted EPS at its early-2026 high (~$171). That is a ~50% multiple compression on a business guiding to mid-teens growth. The headline trailing GAAP P/E (~48×) is meaningless — it divides price by a $2.02 GAAP figure distorted by the non-cash NCI increment and amortization. On its own ten-year history, CIGI sits in the <1st percentile on price/book and ~1st percentile on price/sales — near the cheapest it has ever been on those measures (the composite percentile, ~17th, is dragged up only by the not-meaningful GAAP P/E).

10.2 Peer context (June 2026)

CIGI sits mid-pack with the brokers on EV/EBITDA and below the engineering roll-ups (WSP/Stantec ~14–15×) — despite roughly half its EBITDA coming from engineering (A–/B+) and alt management (A) that individually command richer multiples. The market is applying a brokerage/complexity multiple to a higher-quality blend.

10.3 Sum-of-the-parts — the core argument

Valuing each segment at a defensible, segment-appropriate multiple of FY2025 Adjusted EBITDA, then netting net debt and the full $1.285B redeemable-NCI claim (the disciplined choice — segment EBITDA is consolidated, so the minority’s share must be deducted):

The full range: bear ~$92, base ~$122, bull ~$152. At ~$97 the market is paying the bear-to-low end of a defensible parts valuation. The IM cross-check corroborates: Harrison Street at ~3% of $108B AUM ≈ $3.2B ≈ the base EV — and that single segment is ~65–85% of CIGI’s entire $4.95B market cap. Buy the equity here and the alt manager nearly covers the check; the #3–4 global brokerage and the engineering franchise come close to free. Skeptic’s caveat: if one declines to deduct the full RNCI (arguing some puts lapse or settle accretively), an 80%-deduction lifts the base toward ~$127; deduct it in full, as I do, and the base is ~$122 — either way, above the ~$97 spot.

10.4 Embedded expectations

A reverse read of ~13× forward on a mid-teens guider implies the market is pricing only ~mid-single-digit through-cycle EPS growth and/or a permanently elevated risk premium — well below the company’s historical and guided trajectory. If Colliers merely delivers its mid-teens guide for 2–3 years at an unchanged 13×, EPS to ~$8.5–9.7 (FY27–28) supports ~$110–126 on multiple-hold alone; a partial re-rate toward 16–17× (still far below the 26× peak) plus growth approaches the bull SOTP. The de-rating is partly justified (leverage to ~3×, cyclical brokerage, rate uncertainty) and partly sentiment (RE-services out of favor, no buyback signal).

Verdict (Valuation): On adjusted earnings, EV/EBITDA, FCF yield, own-history percentiles, and a parts-based valuation, CIGI screens cheap to fair-value-with-margin — the market is underwriting a near-trough multiple on a mid-teens compounder and crediting almost nothing for the asset-management and engineering quality. The valuation embeds pessimism the fundamentals do not yet corroborate.

11. Variant Perception

Consensus view: Sell-side is constructive (≈13 analysts, mostly Buy, no sells; average target ~$148 — we do not adopt this), but the market’s revealed view, via the ~50% multiple compression, is bearish/skeptical: a cyclical real-estate-services name with ugly GAAP earnings, rising leverage, a founder supervote, and flat IM organic fees, fairly de-rated in a risk-off tape.

Strongest bull case: A ~15–17% per-share compounder with a 31-year record is being priced as a distressed cyclical at ~13× forward / <1st-percentile own-history P/B-P/S, when a sum-of-the-parts says Harrison Street alone is ~65–85% of the market cap and the engineering and alt-management engines deserve higher multiples than the brokerage label implies. The capital-markets cycle is turning up off a multi-year trough (CapMkts +43% in Q1’26), FCF converts at ~105% of adjusted earnings (~7% yield), the governance overhang self-extinguishes by 2028, and a respected value fund (Spruce House) is buying. Mean-reversion of the multiple plus mid-teens growth is a powerful combination.

Strongest bear case: The GAAP earnings are ugly for a reason — the partnership/RNCI model siphons real value to minority partners ($1.285B claim, growing), SBC is real dilution, and the “adjusted” number flatters. Leverage is rising to ~3× into a still-fragile, rate-hostage CRE recovery; Ayesa was bought at a full ~11× in a hot M&A market; IM organic fees are flat; and a founder controls ~42% of the vote. A 13× multiple on a cyclical, financially-engineered, founder-controlled roll-up may be correct, not cheap — and there is no buyback to defend the floor.

The 3–5 assumptions that matter most:

1. Does the CRE capital-markets recovery continue (bull) or relapse on a rate spike (bear)?
2. Does Investment Management organic fee growth inflect positive (bull) or stay flat/decline (bear)? — the swing variable for the alt-manager re-rating.
3. Is the $1.285B RNCI a real, full deduction from equity value (bear) or partially recoverable/accretive (bull)?
4. Does Ayesa integrate cleanly and leverage normalize back toward ~2× (bull) or slip (bear)?
5. Does the market re-rate the multiple toward the higher-quality blend (bull) or keep a permanent brokerage/complexity discount (bear)?

What would falsify each side: Bull falsified by two quarters of capital-markets re-deceleration + IM net outflows + leverage stress. Bear falsified by continued CapMkts growth + IM organic fee inflection + a buyback initiation at these prices.

Verdict (Variant Perception): The variant perception is that the market is mistaking accounting opacity and cyclicality for poor business quality, and pricing the parts as if the best ones (alt management, engineering) didn’t exist. The bear case is real but bounded; the asymmetry favors the patient buyer.

12. Fact vs. Interpretation Table

13. Open Questions

1. Exact post-Ayesa diluted share count and pro-forma leverage trajectory through 2H’26.
2. Will RNCI puts settle in cash or shares, and what is the multi-year cash/dilution schedule of the $1.285B claim?
3. Investment Management organic fee growth ex-catch-up and ex-acquisition — the key quality signal; is the flat FY2025 a lapping artifact or a trend?
4. Harrison Street’s fee-related-earnings vs performance-fee split — needed to tighten the alt-manager multiple.
5. Will management initiate a buyback at a decade-cheap valuation once leverage normalizes, given Hennick’s “below intrinsic value” comment?
6. Data-center fee durability — does AUM mix toward data centers help or eventually compress IM fee rates?
7. Management stretch — Christian Mayer holding both Global CFO and CRE CEO roles.

14. What Must Be True

Bull case — what must be true:

• The CRE capital-markets recovery continues for 2–3 years (volumes still ~30% below peak), driving operating leverage on the highest-margin line.
• Investment Management fundraising hits $6–9B and organic fees inflect positive, supporting an alt-manager re-rating of the segment.
• Ayesa integrates cleanly and leverage normalizes back toward ~2× by 2027.
• The market re-rates the multiple from ~13× toward the higher-quality blend (~16–18×) as the engineering/alt mix becomes undeniable.
• Falsification test: Two consecutive quarters of capital-markets revenue deceleration, OR Investment Management net outflows / continued flat-to-negative organic fees, OR leverage stuck above ~3× through 2027. Any of these breaks the compounding-at-a-discount thesis.

Bear case — what must be true:

• A rate spike or recession relapses the CRE cycle, with brokerage volumes rolling over while leverage sits at ~3×.
• The RNCI/partnership model proves a persistent drain on per-share value (cash buyouts + dilution), validating the GAAP-over-adjusted skeptics.
• IM organic fees stay flat or decline, denying the alt-manager re-rate.
• The founder-control/complexity discount is permanent, not transitional.
• Falsification test: Continued capital-markets growth + IM organic fee inflection + a buyback initiated at these prices — any of which would confirm the de-rating was sentiment, not substance.

APPENDIX A — Standard Diligence Questionnaire

Colliers International Group Inc. (NASDAQ/TSX: CIGI) — as of June 12, 2026

Supplemental to the article. Fact / Interpretation / Assumption labels used where it matters.

General

What thoughtful questions have other investors asked about this company? The recurring institutional questions: (1) Is Colliers a cyclical brokerage or a diversified compounder — and which multiple does it deserve? (2) How should one read the wide GAAP-vs-adjusted earnings gap, and is the NCI redemption increment “real”? (3) What is Harrison Street worth as a standalone alt manager, and does the sum-of-the-parts exceed the whole? (4) Was Ayesa overpriced, and is ~3× leverage prudent? (5) When does the Hennick dual-class structure collapse, and what happens to control/culture afterward? (6) Why no buyback at a decade-cheap valuation? (Interpretation, from transcripts, analyst Q&A, and the Spruce House 13D.)

Cyclicality & Earnings Nature

Are earnings at a cyclical high or low? Mixed, tilted toward a cyclical low in the largest segment. Commercial Real Estate capital-markets revenue is recovering off a multi-year trough — global transaction volumes remain ~30%+ below the 2021 peak (Fact, MSCI/CBRE data), so brokerage earnings are below mid-cycle. Investment Management and Engineering earnings are nearer normal/structurally growing. Net: consolidated earnings are not at a cyclical high — the most cyclical line is recovering, not peaking. (Interpretation.)

Driven by external environment or internal actions? Both. External: the rate/transaction cycle drives CapMkts; fundraising cycle drives IM. Internal: the deliberate shift to recurring revenue (>70% of earnings), acquisitive engineering build-out, and Harrison Street consolidation are management-driven. (Fact/Interpretation.)

How stable are revenues? Bifurcated: ~70% recurring (outsourcing, engineering backlog, IM fees, mortgage servicing) is stable; ~30% transactional (capital markets, leasing) is volatile. The blend is far steadier than a pure broker. (Fact.)

Outlook for products/services? Management guides mid-teens growth in revenue, Adjusted EBITDA and Adjusted EPS in 2026 (Assumption — guidance, a hypothesis). FY2026 segment drivers: CapMkts ~+25%, Leasing ~+8%, Outsourcing ~+5%, plus Engineering acquisitions and IM fundraising.

How big is this market — growing, shrinking, domestic or international? Global and growing. CRE services (~$300B+ global industry, recovering); engineering/infrastructure consulting (multi-trillion infrastructure tailwind); real-asset alt management (secular growth in data centers and demographic real assets). Colliers operates across the US, Canada, Europe, UK, Australia, Asia — genuinely international. (Fact.)

Business Quality & Competitive Moat

Is the industry getting more or less competitive? CRE brokerage: stable oligopoly at top, competitive for talent. Engineering: consolidating (roll-up wave) — more capital competing for deals. Alt management: competitive for capital but high-switching-cost once committed. (Interpretation.)

How profitable is the business (ROIC, ROE)? ROE ~8.5% on GAAP (depressed by amortization/NCI optics); on adjusted earnings and a goodwill-heavy capital base, returns are good not spectacular — the compounding comes from reinvestment + multiple arbitrage, not extraordinary returns on capital. IM segment earns ~43% net margins (very high); brokerage/engineering ~12–13%. Capital intensity is trivial (capex ~1.4% of revenue). (Fact/Interpretation.)

How profitable is the industry — competitors, barriers? Tiered. Alt management: high barriers (track record, committed capital), high margins. Engineering: moderate barriers (credentials, backlog), mid-teens margins. Brokerage: low-moderate barriers (brand, scale, data), people-driven, cyclical margins. (Interpretation.)

Can the business be easily understood? Only partly — the three-segment structure, IFRS reporting, the partnership/RNCI plumbing, and the GAAP-vs-adjusted gap make it more complex than average; the complexity is part of the mispricing. (Interpretation.)

Can it be undermined by foreign low-cost labor? Largely no — services are local, relationship-, license-, and presence-driven. Some back-office/engineering-design work is offshore-able (and AI-exposed), which Colliers is addressing via its Google partnership. (Interpretation.)

Do brands matter? Yes — “Colliers” and “Harrison Street” are real brands that win mandates and raise capital; brand is a component of the moat, especially in IM and corporate accounts. (Fact/Interpretation.)

Nature of competition? Brokerage: for producers and mandates vs CBRE/JLL/CWK/Newmark. Engineering: for projects/backlog and acquisitions vs WSP/Stantec/AECOM. IM: for LP capital vs other real-asset managers. (Fact.)

Customers’ switching costs? High in outsourcing/servicing and IM (committed capital, operational integration); low at the brokerage-deal level (portable talent, re-bid mandates). (Interpretation.)

Financial Condition & Balance Sheet

Assets not fully recognized on the balance sheet? Yes — the Harrison Street/IM franchise’s intangible value (brand, track record, fund relationships) and the brokerage/engineering producer networks are worth far more than book; this is the core of the SOTP > market-cap argument. (Interpretation.)

Off-balance-sheet liabilities? The redeemable NCI ($1.285B) is on the balance sheet as mezzanine equity (not hidden). Operating leases are capitalized ($519M of lease liabilities). Mortgage warehouse facilities are largely offset by warehouse receivables (matched). No major undisclosed off-balance-sheet exposures identified. (Fact.)

How conservative is the accounting? IFRS; non-GAAP “adjusted” measures are aggressive in places (adding back SBC and the NCI increment, both real costs) — but cash conversion (105% of adjusted earnings) corroborates the adjusted figure over the depressed GAAP figure. Net: adjusted measures flatter, but cash supports them; treat owner-earnings as below the $6.58 adjusted figure. (Interpretation.)

How CapEx-hungry? Not at all — capex ~1.4% of revenue. Growth capital goes to acquisitions, not capex. (Fact.)

Capital Allocation & Management

How much FCF, and how is it used? FY2025 FCF ~$352M (105% of adjusted net earnings, ~7% of market cap). Used primarily for acquisitions ($262M FY2025), a token dividend ($15M), and NCI distributions/buyouts (~$115M); no buybacks in 2025. Philosophy: reinvestment compounding, not capital return. (Fact.)

Significant acquisitions recently? Yes — Englobe (engineering), multiple Quebec tuck-ins, and the transformational Ayesa (~US$700M, ~11× 2026E EBITDA, closed May 2026). Earlier: Harrison Street (2018), Basalt. (Fact.)

Buying back shares? No (2025). FY2024 issued ~$287M of subordinate voting shares. (Fact — a mild negative given the cheap valuation.)

Issuing large amounts of stock to insiders? The partnership puts can settle in shares (dilutive); the CEO LTIP is share-based. Post-2021, Hennick takes no equity-linked comp. (Fact.)

Compensation policy / motivations of management? Operators hold puttable subsidiary equity (“operators are owners”); CEO LTIP is performance-based; Hennick’s pay is a management-services fee with no LTIA/options post-2021. Broadly well-aligned to per-share value and subsidiary earnings. (Fact/Interpretation.)

Valuation & Market Data

Is the stock an ADR, MLP, or K-1 issuer? Neither ADR, MLP, nor K-1. It is a Canadian company listed on NASDAQ and TSX, filing 40-F + 6-K as an MJDS foreign private issuer, reporting in USD under IFRS. Standard common-share (subordinate voting) holding for a US investor; no K-1. (Fact.)

Dividend policy? Token: $0.30/share annual (~0.3% yield, ~5% payout). Not an income vehicle. (Fact.)

How profitable is the business? See above — high-margin IM, mid-teens-margin engineering/brokerage; ~15% consolidated Adjusted EBITDA margin on net revenue; excellent cash conversion. (Fact.)

Net income diverging from cash from operations? Yes — GAAP net income to Company ($103M) is far below OCF ($330M) and FCF ($352M), because of non-cash charges (amortization, NCI increment). Cash flow is the truer signal and tracks adjusted earnings. (Fact/Interpretation.)

Risks & Downside

Factors that would cause the stock to decline? A rate spike/recession relapsing the CRE cycle; Ayesa integration problems / leverage stress; IM net outflows or fee compression; a broader risk-off in cyclical/real-estate names (as in spring 2026); evidence the RNCI/partnership model is a persistent per-share drain. (Interpretation.)

Risk of catastrophic loss? Low — diversified across three businesses, geographies and ~70% recurring revenue, with moderate (if rising) leverage and strong cash generation. No single point of failure. (Interpretation.)

Chance of total loss? Very low — established, profitable, cash-generative, moderately levered global franchise. A total loss would require a prolonged CRE depression coinciding with peak leverage and an IM collapse simultaneously. (Interpretation.)

Recent News & Events

Has the business environment changed recently? Yes — (1) CRE capital markets are recovering (CapMkts +43% Q1’26); (2) a spring-2026 risk-off de-rated the stock ~43% from its high amid rate/geopolitical fears; (3) the engineering segment was transformed by Ayesa; (4) the dual-class sunset clock (≤Sept 1 2028) is now ~27 months out; (5) Spruce House filed a 13D at 5.04% (Apr 2026). (Fact.)

Significant acquisitions? Ayesa (~$700M, closed May 2026); ongoing engineering tuck-ins. (Fact.)

Change in accounting policies? Re-segmentation into Commercial Real Estate / Engineering / Investment Management (prior periods recast); a modest Engineering↔CRE realignment in Q1’26. No change in accounting framework (still IFRS). (Fact.)

Recent changes — new markets, facilities, management? Ayesa opens 4–5 new engineering markets; new segment CEOs (Mulamoottil for Engineering; Mayer adds CRE CEO to his CFO role); deepened Google AI/cloud partnership. (Fact.)

Notes on data conventions

• Colliers reports in US dollars under IFRS; “net revenue” excludes subconsultant/pass-through costs and historical pass-through performance fees.
• Adjusted EBITDA / Adjusted EPS / FCF are company-defined non-GAAP measures; the memo treats owner-earnings as below the headline Adjusted EPS because SBC and the NCI redemption increment are real economic costs (Section 6).
• Peer EV/EBITDA definitions vary ±1–2 turns across vendors; load-bearing figures reconciled to filings where possible.
