18 Best M&A Advisors in Chicago for $1M-$500M Deals (2026 Guide)

Last updated: April 2026

We run Peony, a data room platform for M&A and private equity. Chicago is one of the three cities (Dallas and Atlanta being the other two) where we see the most boutique M&A advisor deal flow on the platform. The reason is structural: Illinois generates $913.7B in GDP, the Chicago metro hosts 4.71M workers across one of the deepest industrial bases in the United States, and the metro's lower-middle-market is overwhelmingly served by Chicago-headquartered boutiques rather than the bulge-bracket banks that dominate New York or San Francisco coverage.

I co-founded Peony after eight years on the investor side -- first as a venture capitalist at Backed VC, then as a growth equity investor at Target Global covering late-stage and secondary deals -- and a brief earlier stint in M&A at Nomura. From the investor seat at Backed VC and Target Global, I worked alongside Chicago boutiques on industrials, healthcare, and consumer transactions, sat through dozens of management presentations from sell-side advisors, and watched the same handful of mistakes ruin good deals: bad CIMs, disorganized data rooms, advisors who could not answer customer concentration questions in real time, and seller-side processes that lost momentum because nobody could tell which buyer was actually engaged. Now at Peony I work directly with dozens of M&A advisors, independent sponsors, and PE deal teams running diligence across our platform. Building this Chicago guide as part of our city series -- see also our Dallas guide.

This guide maps 18 verified Chicago-headquartered or Chicago-led M&A advisory firms active in the $1M-$2B+ deal range as of April 2026. Every firm has been verified for Chicago presence, deal size band, and recent transaction activity.

TL;DR: Illinois generates $913.7B in GDP and the Chicago metro hosts 4.71M workers, of which roughly 370K (about 9.4% of the labor force) work in manufacturing -- one of the deepest industrial bases in the US. Chicago industrial real estate sales hit $1.95B in 2025 and Illinois recorded roughly 600-700 M&A deals in 2024. For Chicago founders selling between $1M and $2B+, the right answer is almost always a Chicago boutique: Lincoln International, William Blair, Houlihan Lokey, and Mesirow at the top of the market; BGL, Livingstone, Peakstone, PMCF, Dresner, and Auctus in the core middle-market; Prairie, Sikich IB, Cabrera, and Capstone in the lower-middle-market; and Sun, Ravinia, Origin Merchant, and Fultonbridge for sub-$10M EV deals. Below: the firms, the deal-size bands, the fees, and three recent verified Chicago-led closes that show how each tier actually works.

How I Verified This List

Every firm on this list passes four filters:

1. Chicago-area headquarters or principal Chicago office -- not a satellite branch staffed by one analyst
2. Verifiable transaction record -- closed at least 5 transactions in the $1M-$2B+ EV range in the last 36 months, sourced from press releases, Axial deal feeds, LSEG league tables, or firm announcements
3. Active 2024-2026 deal activity -- not a legacy firm coasting on pre-2020 relationships
4. Lower-middle-market, middle-market, or upper middle-market focus -- I dropped any firm whose median deal is below $1M revenue (true business brokers) or that runs almost exclusively bulge-bracket $2B+ engagements where Chicago geography stops mattering

I cross-referenced firm websites against Axial's 2024-2025 Top 100 LMM Investment Bank rankings, LSEG's North America M&A league tables for sub-$500M deals, and the Association for Corporate Growth (ACG) Chicago chapter rosters. Where a firm claimed Chicago leadership but the senior team was actually based elsewhere, I dropped it.

Deqian Jia, my co-founder, adds the technical readiness lens here:

"Across the Chicago data rooms we host, the gap between advisors who consistently close in 90 days and those who run six-month processes is preparation. The fast advisors arrive at engagement with the QofE already drafted, the data room indexed by AI, and the management team rehearsed for buyer presentations. The slow ones spend the first six weeks on cleanup work that should have happened pre-engagement. When you're picking a Chicago advisor, ask to see a sample data room from a recent close -- not a pitch deck. The folder structure tells you everything." -- Deqian Jia, Peony co-founder

Why Does Chicago Matter for Lower-Middle-Market and Middle-Market M&A?

Chicago in 2026 sits among the top US M&A markets by deal volume and is the dominant Midwest hub by a wide margin. The math:

• Illinois GDP: $913.7B in 2024
• Chicago metro labor force: 4.71M workers
• Manufacturing share: roughly 9.4% of the metro labor force, or about 370K manufacturing jobs -- one of the deepest industrial bases in the US
• Chicago industrial real estate sales: $1.95B in 2025
• Illinois M&A deal count: roughly 600-700 deals in 2024
• Chicago-headquartered middle-market firms: Lincoln International, William Blair, Houlihan Lokey (Chicago co-HQ), Mesirow, BGL, Livingstone, Peakstone, PMCF, Dresner, Auctus all anchor the global middle-market

Why this matters for sellers: the Chicago lower-middle-market and middle-market have a deeper boutique-advisor bench than any US city outside New York. Chicago-based PE platforms (Madison Dearborn Partners, GTCR, Wynnchurch, BDT & MSD, Linden Capital, Prospect Partners, Wind Point Partners), Chicago-based growth equity (HC Private Investments, Pelican Energy Partners adjacent platforms, NextGen Growth Partners), and Midwest-regional PE firms (Blackford Capital, Cuyahoga Capital Partners, Centerfield Capital) all evaluate Chicago deals as part of their core geography. Out-of-state PE firms (Sun Capital, KKR, Audax, HIG, Vista, Insight) maintain Chicago coverage teams. The result is a deeper buyer pool than equivalent-size businesses in most US metros see for the same EBITDA range.

What Should I Look For in a Chicago M&A Advisor?

Three filters matter more than firm prestige for sub-$500M deals:

1. Sub-sector deal density. A Chicago advisor who has closed 10 industrial container, packaging, or food manufacturing platform sales in the last three years will run a tighter process than a generalist who has closed 50 deals across 15 sectors. Sub-sector density compounds: the advisor knows which PE platforms are active, which strategic acquirers are filling holes in their footprint, what working capital adjustments are standard, and what customer concentration thresholds will trigger an earnout structure. Ask any candidate Chicago advisor to name five recent buyers of comparable businesses in your sector. If they cannot, move on.

2. Buyer Rolodex relevance. The right Chicago advisor maintains direct relationships with the 30-50 buyers most likely to acquire your specific business. For a $25M industrial container manufacturer, that means relationships with Pelican Energy Partners, Wynnchurch Capital, Blackford Capital, and the Midwest-based PE platforms backing industrial roll-ups. For a $200M healthcare services business, that means relationships with Linden Capital, Beecken Petty O'Keefe, Water Street Healthcare, and the strategic acquirers in your healthcare sub-vertical. A bigger firm with a thinner relationship-per-buyer ratio runs slower processes than a boutique with deep relationships in your sub-sector.

3. Process discipline. The fast Chicago advisors (Lincoln International, William Blair, Houlihan Lokey, Mesirow, BGL, Livingstone, Peakstone, PMCF) run 4-6 month processes from engagement to close. The slow ones run 9-12 month processes. The difference is preparation, not market conditions. Fast advisors arrive at engagement with the QofE provider already engaged, the data room template ready to populate, and the management team pre-briefed on buyer presentation expectations. Slow advisors do that work after engagement, which means the first 6 weeks of your exclusivity window evaporate before the first buyer call.

For deeper context on M&A preparation and the due diligence process, see our M&A guides. For data room setup specifically, our M&A data room guide covers what advisors expect to see ready by week 1 of the engagement.

Tier 4: Lincoln International, William Blair, Houlihan Lokey, Mesirow (Upper Middle-Market and Mid-Market Volume Leaders)

These four firms anchor the upper end of the Chicago M&A market. All four maintain dedicated industry verticals, all four close 100+ transactions per year at the firm level, and all four show up in 2024-2025 LSEG league tables for North America middle-market M&A. If your deal is between $150M and $2B+ EV, you should be talking to at least two of these four during the pitch process.

1. Lincoln International

Headquarters: Chicago (founded 1996 as Lincoln Partners, a Chicago boutique) Founded: 1996 Team: ~1,400+ professionals across 25-30 offices globally Deal size: $75M-$2B+ EV (sweet spot $150M-$500M) Sectors: Industrial, healthcare, business services, technology, consumer, financial services Track record: Consistently ranked among the top global middle-market M&A advisors in LSEG and Refinitiv league tables; advised on hundreds of M&A transactions globally per year

Lincoln International is one of the largest dedicated middle-market M&A advisors in the world, founded in Chicago in 1996 by Jim Lawson, Rob Barr, Ed Hanlon, and Eric Malchow as Lincoln Partners. The firm's structural focus on $75M-$500M EV deals means its senior bankers run mid-market processes as core engagements rather than as a step-down from bulge-bracket transactions. Lincoln's PE-platform Rolodex is among the deepest globally, and the firm's Frankfurt, London, Tokyo, and Mumbai offices produce real cross-border outreach for Chicago sellers whose buyer pool tilts international.

Best for: Sellers in the $150M-$500M EV sweet spot who want a global middle-market firm headquartered in Chicago. Lincoln's PE-platform coverage is structurally built for processes where the buyer pool is heavily middle-market PE.

Considerations: Lincoln's lower-middle-market deal flow is real but the firm's structural sweet spot starts at $75M EV and accelerates above $150M. Below $75M EV, you'll get a vice president running execution rather than the managing director who pitched the deal.

2. William Blair

Headquarters: Chicago Founded: 1935 Team: ~2,000 employees globally across 20+ offices; integrated investment banking, equity research, ECM, and asset management Deal size: $150M-$2B+ EV Sectors: Healthcare, technology, business services, consumer, industrial, financial services Track record: Consistently ranked among the top global middle-market M&A advisors; integrated investment banking, equity research, equity capital markets, and asset management

William Blair is a Chicago-headquartered investment bank founded in 1935 by William McCormick Blair that runs one of the most-respected middle-market M&A practices in the United States. The firm's structural advantage is integrated capability: M&A advisory, equity research, ECM, and asset management all sit inside the same firm, which produces direct relationships with strategic acquirers and growth equity buyers that pure-play M&A boutiques can't match. William Blair's healthcare and technology practices are among the deepest middle-market practices globally.

Recent closes: Moss Inc. (Franklin Park, Illinois, founded 1975) to Vomela (December 15, 2025) -- William Blair acted as financial advisor to Moss Inc., then a portfolio company of EagleTree Capital, on its sale to The Vomela Companies, a portfolio company of The Riverside Company, in an experiential events and large-format printing roll-up consolidation.

Best for: Sellers in healthcare, technology, growth-company, and large-cap industrial categories who want a firm with deep strategic-buyer relationships and public-market exit optionality. William Blair wins when your buyer pool is heavily strategic acquirers or growth equity buyers.

Considerations: William Blair's structural sweet spot starts at $150M EV. Below that band, BGL, Livingstone, Peakstone, or Mesirow are better-aligned with the deal size.

3. Houlihan Lokey (Chicago Office)

Headquarters: Los Angeles (corporate); large Chicago office anchoring the Midwest middle-market practice Founded: 1972 Team: 2,700+ employees globally; sizeable Chicago presence Deal size: $50M-$2B+ EV Sectors: Industrial, financial services, restructuring, business services, technology, consumer Track record: Top-ranked global M&A advisor by deal count for multiple consecutive years (415 deals in 2024 per LSEG; #1 by volume in 2025); leading global restructuring advisor

Houlihan Lokey is one of the largest middle-market M&A and restructuring firms in the world and runs a major Chicago office that anchors the firm's Midwest middle-market practice. The firm's restructuring capability is unique among Chicago-active middle-market firms -- if your business has covenant or capital structure issues, Houlihan Lokey is the only Chicago-active firm with a top-tier restructuring practice running in parallel to M&A advisory.

Best for: Sellers in $75M-$500M EV deals where complex capital structure, restructuring optionality, or mid-market PE outreach matters. Houlihan's Chicago industrial practice is among the deepest middle-market practices in the metro.

Considerations: At $50M EV (the bottom of Houlihan's stated band), you'll likely get a vice president running execution rather than the managing director who pitched the deal. For $25M-$75M EV deals, Mesirow, BGL, and Livingstone are better-aligned with senior-banker engagement levels.

4. Mesirow Investment Banking

Headquarters: Chicago Founded: 1937 (Mesirow Financial); investment banking practice anchored in Chicago Team: ~50+ investment banking professionals Deal size: $25M-$500M EV Sectors: Healthcare, industrial, business services, consumer, financial services Track record: 80+ years of Chicago middle-market coverage; dedicated industry verticals across healthcare, industrial, and services

Mesirow Investment Banking is the M&A practice within Mesirow Financial, a Chicago-headquartered diversified financial services firm founded in 1937. The investment banking team runs middle-market M&A advisory across healthcare, industrial, business services, and consumer sectors with a Chicago-anchored deal flow that produces direct relationships with Chicago and Midwest PE platforms.

Best for: Sellers in $25M-$200M EV deals who want a Chicago-headquartered firm with dedicated industry verticals. Mesirow's healthcare practice is particularly strong in Chicago middle-market healthcare services.

Considerations: Mesirow's cross-border reach is thinner than Lincoln, William Blair, or Houlihan Lokey. For Chicago deals where 40%+ of the buyer pool is non-North American, supplement Mesirow with one of the global middle-market firms.

Tier 3: BGL, Livingstone, Peakstone, PMCF, Dresner, Auctus (Core Middle-Market)

These six firms anchor the $25M-$300M EV core of the Chicago middle-market. They run smaller teams than Tier 4, cover narrower sub-sectors, and typically charge slightly lower retainer fees. If your deal is between $25M and $150M EV, this tier should be your primary search.

5. BGL Capital Partners (Brown Gibbons Lang)

Headquarters: Cleveland (corporate); Chicago is BGL's largest office (opened 1995) Founded: 1989 Team: ~200 professionals firm-wide; ~40+ in Chicago Deal size: $50M-$300M EV Sectors: Industrial, food and beverage, consumer, business services, healthcare, environmental and industrial services Track record: Active middle-market industrial and food manufacturing practice; consistent Chicago and Cleveland deal flow

Brown Gibbons Lang Capital Partners (BGL) is a Cleveland-Chicago middle-market M&A boutique with one of the deepest food and beverage manufacturing practices in the Midwest. Founded in 1989 by Michael Gibbons, BGL opened its Chicago office in 1995 and Chicago has since become the firm's largest office. The firm's structural advantage is sector specialization: BGL's Food and Beverage practice is recognized as a leader in middle-market food and beverage M&A.

Recent closes: Specialty Bakers LLC to HC Private Investments (June 24, 2025) -- BGL's Food and Beverage team served as exclusive financial advisor to Specialty Bakers, a Marysville, Pennsylvania-based bakery (founded 1901) and former portfolio company of Stonebridge Partners, on its sale to Chicago-based HC Private Investments. Note: the seller is Pennsylvania-based; the BGL team and the buyer are both Chicago-anchored, which is why the deal landed on a Chicago-active advisor's roster.

Best for: Sellers in food and beverage manufacturing, industrial manufacturing, environmental services, and consumer businesses in the $50M-$200M EV range. BGL's Chicago-Cleveland axis produces deal flow that's heavily Midwest industrial.

Considerations: BGL's technology and software deal flow is thinner than Lincoln, William Blair, or Mesirow. For Chicago tech sellers, look at the Tier 4 firms or Origin Merchant Partners.

6. Livingstone Partners

Headquarters: Chicago (US headquarters; integrated globally with London, Madrid, and Düsseldorf offices) Founded: Chicago office founded 2007 by David Sulaski and Stephen Miles (both ex-BGL); part of a global Livingstone partnership with London and Madrid Team: ~90 professionals globally; ~25 in Chicago Deal size: $25M-$250M EV Sectors: Industrial, consumer, business services, healthcare Track record: Active Chicago middle-market practice with dedicated cross-border (US-UK-Germany-Spain) capability

Livingstone Partners is a Chicago-London-Madrid-Düsseldorf middle-market M&A boutique that runs a serious cross-border practice for Chicago sellers whose buyer pool tilts European. The Chicago office was founded in 2007 by David Sulaski and Stephen Miles as part of a global Livingstone partnership. The firm's structural advantage is the integrated US-Europe deal flow: Livingstone has closed dozens of Chicago middle-market deals where European strategic acquirers were lead bidders, which is rare among Chicago-active boutiques.

Recent closes: Skolnik Industries to Pelican Energy Partners (December 31, 2024) -- Livingstone Partners advised Skolnik Industries, a family-owned Chicago industrial container manufacturer founded in 1928, on its sale to Texas-based Pelican Energy Partners. The transaction is a representative example of Chicago multi-generational family-owned industrial succession into a PE platform.

Best for: Sellers in $25M-$150M EV deals where multi-generational family-owned succession or cross-border (US-Europe) buyer outreach matters. Livingstone's family-owned succession practice is particularly strong.

Considerations: Livingstone's pure-Chicago deal flow is meaningful but the firm's structural advantage is cross-border. If your buyer pool is 100% North American, Mesirow, BGL, Peakstone, or PMCF may be better-aligned.

7. Peakstone Group

Headquarters: Chicago Founded: 2008 (Co-Founder & Managing Partner: Alex Fridman) Team: ~40+ investment banking professionals (~50 firm-wide); over 500 transactions completed firm history Deal size: $25M-$150M EV Sectors: Industrial, consumer, business services, healthcare Track record: Consistent Chicago middle-market deal flow across multiple sectors

Peakstone Group is a Chicago-headquartered middle-market M&A boutique founded in 2008 by Alex Fridman that runs sector-specialized teams across industrial, consumer, business services, and healthcare. The firm's structural advantage is senior-banker engagement: Peakstone's senior bankers average over 25 years of experience, and the managing director who pitches the deal is the one running execution.

Best for: Sellers in $25M-$100M EV deals who want a Chicago-headquartered boutique with senior-banker-led process discipline. Peakstone is a particularly strong fit for Chicago LMM industrials in the $25M-$75M EV band.

Considerations: Peakstone's cross-border reach is thinner than Livingstone or Lincoln. For deals where European or Asian buyers are likely lead bidders, supplement Peakstone with a global middle-market firm.

8. PMCF (Plante Moran Corporate Finance)

Headquarters: Chicago and Detroit (anchored to Plante Moran's largest Midwest offices) Founded: 1995-1996 (as P&M Corporate Finance, the investment banking arm of Plante Moran; Plante Moran founded 1924) Team: 50+ professionals; 300+ transactions completed since inception Deal size: $25M-$250M EV Sectors: Industrial, manufacturing, business services, food and beverage Track record: Consistent middle-market deal flow; integrated tax, audit, and M&A workflow within Plante Moran (the largest accounting and advisory firm in the Midwest)

Plante Moran Corporate Finance (PMCF) is the M&A practice within Plante Moran, the largest accounting and advisory firm in the Midwest. PMCF was launched in the mid-1990s and has completed 300+ middle-market transactions across the Midwest. The integrated workflow is the firm's structural advantage: PMCF can coordinate the M&A transaction with estate planning, tax structuring, trust optimization, and management equity rollovers without coordinating across multiple firms. For family-owned sellers in particular, this is a meaningful difference.

Best for: Family-owned and founder-led sellers in $25M-$200M EV deals where integrated tax, succession, and M&A workflow matters. PMCF's Plante Moran integration is unique in the Chicago middle-market.

Considerations: PMCF is tightly aligned with Plante Moran's existing client base. If you are not a Plante Moran client, the integration advantage is less meaningful and Peakstone, Livingstone, or BGL may be equally good fits.

9. Dresner Partners

Headquarters: Chicago Founded: 1991 (Founder & CEO: Steven Dresner) Team: ~44 professionals across Chicago, NY, LA, and Palm Beach offices Deal size: $25M-$150M EV Sectors: Industrial, consumer, business services, healthcare Track record: 30+ years of Chicago middle-market coverage across multiple sectors; over $8B in completed transactions firm history

Dresner Partners is one of the longer-tenured Chicago middle-market boutiques, founded in 1991 by Steven Dresner. The firm runs cross-sector advisory across industrial, consumer, business services, and healthcare with a deliberate Chicago-LMM positioning. Dresner is a member of the Mergers Alliance international network for cross-border execution.

Best for: Sellers in $25M-$100M EV deals who want a 30+ year Chicago boutique with deep regional buyer relationships. Dresner's cross-sector coverage is well-aligned with multi-vertical Chicago LMM operators.

Considerations: Dresner's transaction volume per year is lower than BGL, Livingstone, or Peakstone. Ask for closed-deal count over the last 24 months when comparing.

dresnerpartners.com

10. Auctus Capital Partners

Headquarters: Chicago (additional offices in New York, Los Angeles, Palm Beach, and London) Founded: 2015 Team: ~15 professionals across multiple offices Deal size: $10M-$75M EV Sectors: Industrial, business services, consumer, specialty manufacturing Track record: LMM Chicago practice with dedicated industrial and business services coverage

Auctus Capital Partners is a Chicago lower-middle-market M&A boutique founded in 2015 that runs a dedicated industrial and specialty manufacturing practice. The firm's structural advantage is sub-sector specialization in industrial verticals where Chicago and the broader Midwest produce concentrated buyer pools.

Best for: Sellers in $10M-$50M EV industrial, business services, and specialty manufacturing deals who want sub-sector-specialized senior-banker leadership.

Considerations: Auctus is a younger firm than Dresner, BGL, or Livingstone. Healthcare and technology deal flow is thinner than the Tier 4 firms; for healthcare or tech sellers, look at Mesirow, William Blair, or Tier 4 generally.

Tier 2: Prairie, Sikich IB, Cabrera, Capstone (Lower-Middle-Market Specialists)

These four firms anchor the $10M-$150M EV lower-middle-market band where larger firms decline engagements and true business brokers underdeliver. All four run high-volume Chicago practices and have direct relationships with the regional PE platforms and family offices that buy at this size.

11. Prairie Capital Advisors

Headquarters: Oakbrook Terrace, Illinois (Chicago suburbs) Founded: 1996 Team: ~50 professionals; 14+ Managing Directors Deal size: $5M-$75M EV (ESOP advisory specialty extends higher) Sectors: ESOP transitions, industrial, business services, healthcare, manufacturing Track record: Delivers ESOP valuation updates to 300+ ESOP companies annually; one of the deepest ESOP transaction track records in the country

Prairie Capital Advisors is the dominant Chicago-area ESOP M&A specialist, founded in 1996 in Oakbrook Terrace. Prairie itself has been employee-owned since 2012. The firm's ESOP track record is among the deepest in the country, and the senior team has direct relationships with the trustee community and the ESOP-friendly PE platforms that buy from selling shareholders post-transition. Recent representative ESOP transactions include World's Finest Chocolate (2024).

Best for: ESOP transitions and recapitalizations across the Chicago suburbs and the broader Midwest. Prairie's ESOP specialization means tighter timelines, lower friction with the trustee community, and structurally better economics for selling shareholders versus generalist firms running ESOP transactions for the first time.

Considerations: Prairie's open-market sell-side practice is meaningful but the firm's structural advantage is ESOP. For non-ESOP Chicago LMM deals, BGL, Livingstone, Peakstone, PMCF, Sikich IB, or Capstone are equally good fits.

12. Sikich Investment Banking

Headquarters: Chicago (Sikich corporate); investment banking practice within Sikich, a top-30 US accounting and advisory firm Founded: Sikich founded 1982; investment banking practice integrated within the broader firm Team: 30+ investment banking professionals Deal size: $10M-$100M EV Sectors: Industrial, manufacturing, business services, technology Track record: Consistent Chicago LMM deal flow; integrated audit, tax, and M&A workflow within Sikich

Sikich Investment Banking is the M&A practice within Sikich, a top-30 US accounting and advisory firm headquartered in Chicago. Like PMCF's relationship with Plante Moran, Sikich IB's structural advantage is integrated workflow with the broader firm's audit, tax, and advisory capabilities.

Best for: Sellers who are existing Sikich audit or advisory clients in $10M-$75M EV industrial, manufacturing, or business services deals. The integrated workflow produces material time and cost savings versus coordinating across multiple firms.

Considerations: Sikich IB's deal flow outside the Sikich client base is thinner than dedicated Chicago boutiques like Peakstone or BGL. For non-Sikich-client sellers, the integration advantage is less meaningful.

sikich.com

13. Cabrera Capital Markets

Headquarters: Chicago (8 offices nationwide; trading desk in London) Founded: 2001 (Founder & CEO: Martin Cabrera Jr.) Team: ~20 in the Chicago investment banking practice (firm-wide includes broader institutional brokerage and trading staff) Deal size: $5M-$75M EV (M&A practice); separate public finance and institutional brokerage Sectors: Industrial, consumer, business services, public finance, infrastructure Track record: Latino-owned (MBE-certified) investment bank; over $1.8 trillion in lifetime debt and equity issuances

Cabrera Capital Markets is a Chicago-headquartered Latino-owned (MBE-certified) investment bank founded in 2001 by Martin Cabrera Jr. The firm's structural advantage is the dual M&A and public finance capability, which produces deal flow in adjacent sectors (infrastructure, public-sector services, regulated utilities) that pure-play M&A boutiques don't typically cover.

Best for: Sellers in $10M-$100M EV deals across industrial, consumer, business services, and infrastructure-adjacent sectors. Cabrera is also a strong fit for public-sector and minority-owned business sellers where representation and certification matter.

Considerations: Cabrera's pure-play M&A volume per year is lower than BGL, Livingstone, or Peakstone. Ask for closed-deal count over the last 24 months when comparing.

14. Capstone Partners (Chicago Office)

Headquarters: Boston (corporate); subsidiary of Huntington Bancshares since 2022; expanded into Chicago, Atlanta, Boston, and New York via the early-2026 acquisition of TM Capital from Janney Montgomery Scott Founded: 2001 (originally part of Arthur Andersen; legally incorporated 2002 by John Ferrara) Team: 175+ professionals across multiple US offices (~40% headcount growth post-TM Capital) Deal size: $10M-$100M EV Sectors: Industrial, business services, consumer, technology, healthcare Track record: National middle-market platform; expanded Chicago presence after TM Capital acquisition

Capstone Partners is a national middle-market M&A platform headquartered in Boston with a Chicago presence that was deepened in early 2026 via Capstone's acquisition of TM Capital and additional Janney Montgomery Scott practice groups. The firm's structural advantage is the national platform: Capstone Chicago bankers have access to cross-office buyer relationships in Boston, New York, Los Angeles, Atlanta, and other major US markets.

Best for: Sellers in $10M-$100M EV deals who want Chicago senior-banker leadership plus national platform reach. Capstone's national network is meaningful for processes where the buyer pool tilts toward East Coast or West Coast strategics.

Considerations: Capstone's Chicago footprint is newer than Chicago-headquartered firms like Peakstone or Dresner. Confirm the senior banker who will actually run your process is Chicago-based, not parachuted in from another office.

Tier 1: Sun, Ravinia, Origin Merchant, Fultonbridge (Sub-LMM Specialists)

These four firms are the right fit for sellers with $1M-$10M EV businesses who want a single senior advisor running every call -- not a managing director who delegates to associates after the pitch. Tier 1 firms typically run 8-12 simultaneous engagements at the firm level (not per-banker) and produce process discipline that punches above the firm size.

15. Sun Acquisitions

Headquarters: Chicago, Illinois (Sun Acquisitions, LLC; firm operations led by President & Managing Partner Domenic Rinaldi, who acquired the firm in 2005) Founded: Original firm founded in the late 1990s; current leadership in place since 2005 Team: 5-10 professionals Deal size: $2M-$25M EV Sectors: Business services, industrial, consumer, niche manufacturing Track record: Domenic Rinaldi has been involved in 500+ business brokerage and lower-middle-market M&A transactions since 2005

Sun Acquisitions is a Chicago-area sub-LMM boutique and business brokerage firm. President & Managing Partner Domenic Rinaldi acquired the firm in 2005 and has since built it into one of the more active sub-LMM practices in the Chicago metro. The firm's structural advantage is local Chicago metro deal density: Sun has closed deals across the city, suburbs, and exurbs with direct relationships with the regional PE platforms and family offices buying at this size.

Best for: Sellers with $2M-$10M EV businesses in business services, industrial, and consumer who want a Chicago-area boutique with high-volume sub-LMM and business-broker experience.

Considerations: Sun's deal flow above $25M EV is thinner. For deals above $25M EV, Ravinia, Origin Merchant, or Tier 2 firms are better-aligned.

16. Ravinia Capital LLC

Headquarters: Chicago metro area Founded: 1998 (Founder: Tom Goldblatt) Team: ~10 professionals Deal size: $5M-$50M EV Sectors: Business services, industrial, consumer, healthcare services Track record: Long-tenured sub-LMM and LMM Chicago boutique

Ravinia Capital LLC is a Chicago-area sell-side investment bank founded in 1998 by Tom Goldblatt. The firm runs cross-sector advisory across business services, industrial, consumer, and healthcare services with a sub-$50M EV positioning.

Best for: Sellers with $5M-$25M EV businesses across multiple sectors who want a Chicago-area boutique with senior-banker-led process discipline.

Considerations: Ravinia's transaction volume per year is lower than larger Tier 2 boutiques. Ask for closed-deal count over the last 24 months when comparing.

raviniacapitalllc.com

17. Origin Merchant Partners

Headquarters: Toronto (corporate); major Chicago office Founded: 2011 Team: 50+ professionals across Toronto, Chicago, and Montreal Deal size: $5M-$50M EV Sectors: Industrial, healthcare, technology, business services Track record: Active cross-border (Canada-US) middle-market deal flow

Origin Merchant Partners is a Toronto-Chicago middle-market boutique that runs a serious cross-border practice for Chicago sellers whose buyer pool tilts Canadian. The firm's structural advantage is the integrated US-Canada deal flow: Origin has closed dozens of Chicago middle-market deals where Canadian strategic acquirers or PE platforms were lead bidders.

Best for: Sellers in $5M-$25M EV deals where cross-border (Canada-US) buyer outreach matters. Origin is also a strong fit for Chicago technology and healthcare sellers in the $10M-$25M EV band.

Considerations: Origin's pure-Chicago deal flow is meaningful but the firm's structural advantage is cross-border. If your buyer pool is 100% North American with no Canadian tilt, Sun Acquisitions, Ravinia, or Tier 2 firms may be better-aligned.

18. Fultonbridge

Headquarters: Chicago Founded: 2000 Team: Smaller boutique Deal size: $1M-$25M EV Sectors: Business services, industrial, consumer, technology Track record: Long-tenured sub-LMM Chicago boutique

Fultonbridge is a Chicago sub-LMM boutique founded in 2000 with a middle-market sell-side advisory focus. The firm's structural advantage is small-team senior-banker engagement: a smaller team means a senior advisor personally runs every engagement.

Best for: Sellers with $1M-$10M EV businesses who want a small-team boutique and a single senior advisor on every call.

Considerations: Fultonbridge runs a small team and a lower transaction volume than Sun Acquisitions. Ask for closed-deal count over the last 24 months and personal transaction history from the senior team when comparing.

Three Recent Chicago M&A Deals That Show How These Firms Work

Looking at three actual 2024-2025 closes shows how the tier structure plays out in practice across family-owned succession, food manufacturing, and printing roll-ups.

Deal 1: Skolnik Industries to Pelican Energy Partners (December 31, 2024)

Seller: Skolnik Industries, a family-owned Chicago industrial container manufacturer founded in 1928 Buyer: Pelican Energy Partners (Texas-based PE platform) Advisor: Livingstone Partners (Tier 3) Sector: Industrial manufacturing / specialty containers Process notes: Skolnik Industries had been in family ownership for nearly 100 years -- spanning four generations of the Skolnik family. The transaction is a representative example of multi-generational Chicago family-owned industrial succession into a PE platform that promised continuity rather than absorption. Livingstone's family-owned succession practice was the natural fit: the firm has closed dozens of similar Chicago industrial multi-generational sales where the seller cared as much about continuity as about valuation.

Why this matters for sellers: If you are running a multi-generational Chicago family-owned industrial business, the question is not whether PE is buying -- they are. The question is whether your advisor understands family succession dynamics, can structure rollover and earnout terms that protect family employment, and has direct relationships with the PE platforms that promise continuity rather than absorption. Livingstone does. So does PMCF (via the Plante Moran integration with estate and succession planning) and Prairie Capital Advisors (for ESOP-route exits where family ownership transitions to employee ownership rather than PE).

Deal 2: Specialty Bakers LLC to HC Private Investments (June 24, 2025)

Seller: Specialty Bakers LLC (Marysville, Pennsylvania; founded 1901; formerly a portfolio company of Stonebridge Partners). U.S. market leader in niche baked goods (Dessert Shells, French Twirls, Ladyfingers) distributed across 25,000+ grocery and mass retail doors. Buyer: HC Private Investments (Chicago-based PE platform) Advisor: BGL Capital Partners served as exclusive financial advisor to Specialty Bakers (Tier 3; BGL's Food and Beverage team) Sector: Food manufacturing Process notes: This was a cross-state transaction where the seller is Pennsylvania-based, but the BGL deal team and the buyer are both Chicago-anchored, illustrating how Chicago-active advisors source food and beverage manufacturing deal flow well beyond the Chicago metro itself. BGL's Food and Beverage practice is one of the deepest in middle-market food and beverage M&A, and the firm's structural advantage in this transaction was sub-sector relationship density: BGL had closed multiple food manufacturing platform sales in the prior 36 months, which meant the buyer outreach list was tight and the buyer evaluation cycle compressed.

Why this matters for sellers: Sub-sector specialization compounds. A food manufacturing seller who hires a generalist boutique pays the same fees as a seller who hires BGL but runs a longer process with a thinner buyer pool. Sub-sector-specialized advisors (BGL in food manufacturing, Livingstone in family-owned industrial succession, Prairie in ESOP transitions, William Blair in healthcare) compound their advantage on every successive deal in the sub-sector.

Deal 3: Moss Inc. to The Vomela Companies (December 15, 2025)

Seller: Moss Inc., headquartered in Franklin Park, Illinois (Chicago metro), founded 1975; experiential events and visual communications platform; formerly a portfolio company of EagleTree Capital. Buyer: The Vomela Companies, a portfolio company of The Riverside Company; large-format printing and visual communications consolidator with 1,600 employees across 20+ locations post-deal. Advisor: William Blair acted as financial advisor to Moss; Jones Day and Alvarez & Marsal also advised Moss and EagleTree (Tier 4) Sector: Experiential events / large-format printing / visual communications Process notes: This was a roll-up consolidation transaction combining Moss with The Vomela Companies into the world's largest specialist production partner serving live events and experiential industry. William Blair's structural advantage was the firm's strategic-acquirer Rolodex: roll-up consolidators evaluate hundreds of platform additions per year, and the right advisor is the one with direct managing-director-level relationships with the consolidators who can move fastest on a competitive process.

Why this matters for sellers: When your buyer pool is heavily strategic acquirers running roll-up consolidations rather than PE platforms running standalone investments, the advisor selection criteria shift. William Blair, Lincoln International, and Houlihan Lokey all have deep strategic-acquirer relationships across multiple specialty manufacturing sub-sectors. Below the Tier 4 firms, BGL and Livingstone both run roll-up advisory but with thinner strategic-acquirer relationships per buyer.

How Should I Choose the Right Chicago M&A Advisor for My Deal?

The decision framework collapses to three questions:

1. What is my deal size?

• $1M-$10M EV: Sun Acquisitions, Ravinia Capital, Fultonbridge Partners, Origin Merchant Partners (lower band)
• $10M-$50M EV ($1M-$5M EBITDA): Prairie Capital Advisors, Sikich IB, Cabrera Capital, Capstone Partners, Origin Merchant Partners
• $50M-$150M EV ($5M-$15M EBITDA): BGL Capital Partners, Livingstone Partners, Peakstone Group, PMCF, Dresner Partners, Auctus Capital Partners, Mesirow Investment Banking
• $150M-$500M EV ($15M-$50M EBITDA): Lincoln International, William Blair, Houlihan Lokey, Mesirow Investment Banking, BGL Capital Partners (upper band)
• $500M-$2B+ EV ($50M+ EBITDA): Lincoln International, William Blair, Houlihan Lokey

2. What is my sector?

• Industrial manufacturing: BGL, Livingstone, Peakstone, PMCF, Auctus, Sikich IB, Lincoln International, Houlihan Lokey
• Food and beverage manufacturing: BGL Capital Partners (Specialty Bakers close in 2025), PMCF, Lincoln International
• Specialty container and industrial products: Livingstone Partners (Skolnik Industries close in 2024), BGL, Auctus
• Healthcare services: Mesirow, William Blair, Houlihan Lokey, Linden Capital-aligned advisors, BGL, Peakstone
• Technology and software: William Blair, Lincoln International, Houlihan Lokey, Origin Merchant
• Large-format printing and specialty manufacturing: William Blair (Moss Inc. close in 2025), Lincoln International
• ESOP transitions: Prairie Capital Advisors (dominant Chicago specialist), PMCF, Mesirow, Livingstone
• Family-owned succession: Livingstone Partners (Skolnik Industries close in 2024), PMCF, Prairie Capital Advisors
• Cross-border (US-Canada): Origin Merchant Partners, Lincoln International, Houlihan Lokey
• Cross-border (US-Europe): Livingstone Partners, Lincoln International, William Blair, Houlihan Lokey
• Public finance and infrastructure: Cabrera Capital
• Distressed and restructuring: Houlihan Lokey (the dominant Chicago-active firm in restructuring)

3. Am I selling or buying?

• Sell-side (owner-operator exit): All 18 firms run sell-side processes. Sub-$25M EV: Sun Acquisitions, Ravinia Capital, Fultonbridge Partners, Origin Merchant Partners. $25M+ EV: Tier 2-4 firms.
• Buy-side (corporate development or PE platform): Lincoln International, William Blair, Houlihan Lokey, Mesirow, BGL, Livingstone, Peakstone, PMCF, and Capstone all maintain buy-side practices. Smaller boutiques (Sun Acquisitions, Ravinia, Fultonbridge) are sell-side specialists -- not the right fit for buyer-side mandates.

---

What Do Chicago M&A Advisors Charge in 2026?

Fee structures across the 18 firms collapse to three patterns by deal size:

Retainer credit: All 18 firms credit retainer against success fee at close. If the deal does not close, the retainer is generally non-refundable (though the engagement letter is negotiable on this point).

Tail period: 12-24 months covering buyers introduced during the engagement. Negotiate down to 12 months if you can; the default 18-24 month tail can complicate a future re-engagement with a different advisor.

Expense reimbursement: $25K-$75K cap is standard for travel, marketing, and CIM preparation. Above this, the seller pays direct.

ESOP-specific fees: Prairie Capital Advisors and other ESOP specialists typically charge a flat fee for the ESOP-specific work product (fairness opinion, valuation support, trustee coordination) on top of the Lehman-style success fee. Expect $100K-$300K for ESOP-specific work depending on complexity.

How Do Chicago Boutiques Compare to National Banks for Sub-$300M Deals?

The honest answer: for deals under $300M EV, the Chicago boutiques win on three dimensions and tie on one.

Boutiques win on:

• Senior-banker engagement. A Chicago boutique managing director personally runs your process. A New York investment bank assigns a managing director to pitch the deal and then delegates execution to a vice president and two associates. For an $80M deal, this means the senior judgment that gets buyers to LOI lives at the MD level at a boutique and at the VP level at a New York bank.
• Fee economics. Boutiques charge 1.5-3% blended on sub-$300M deals. New York banks charge 2-3% blended plus mandatory minimum success fees ($1M-$2M minimums are standard) that price out sub-$50M deals or produce uneconomic engagements.
• Sub-sector relationship density. A Chicago industrial-focused boutique like BGL or Livingstone knows every PE platform and strategic acquirer in industrial manufacturing. A New York bank covers industrial as one of 30 industry verticals -- the relationship density per buyer is structurally lower.

National banks win on:

• Cross-border or strategic-acquirer-driven processes above $300M EV. If your buyer pool is primarily strategic acquirers across 5+ countries on a $500M+ deal, a New York bank's coverage breadth matters. Chicago does have global middle-market firms (Lincoln, William Blair, Houlihan Lokey) that match this capability without the New York premium.

Tie on:

• Process discipline. The top Chicago boutiques (Lincoln, William Blair, Houlihan Lokey, Mesirow, BGL, Livingstone, Peakstone, PMCF) run processes that are functionally indistinguishable from a New York bank's middle-market process. The CIMs are equivalent in quality, the data rooms are equivalent in organization, and the buyer outreach lists are equivalent in depth. Where the Chicago boutiques pull ahead is on senior-banker engagement and fee economics; where they tie is on the actual mechanical execution.

For an $80M Chicago industrial seller, a $40M Chicago healthcare operator, or a $200M Chicago manufacturing platform, the right answer is almost always a Chicago boutique. New York banks make sense for deals above $300M EV on cross-border strategic processes, businesses with public-market exit optionality, or restructuring engagements where Houlihan Lokey's New York capability is functionally equivalent to its Chicago capability.

What Should I Do Before Engaging a Chicago M&A Advisor?

The fast Chicago advisors (the ones who close in 4-6 months instead of 9-12) all expect the same preparation work to be done before the engagement letter is signed. If you arrive ready, your process compresses by 6-8 weeks.

1. Get the QofE drafted. A Quality of Earnings report from a credible accountant (not your tax CPA) is the single most valuable preparation document. The QofE establishes the EBITDA narrative the buyer will diligence, surfaces working capital adjustments before the buyer finds them, and produces the financial reconciliation that the data room financials should tie to. Allow 6-8 weeks for QofE prep. For deeper context, our M&A due diligence process guide covers the full QofE workflow.

2. Build the data room before pitching advisors. Chicago advisors are universally more enthusiastic about engagements where the seller arrives with an organized data room than ones where the advisor has to spend the first six weeks of the engagement on data room setup. Peony lets you build a complete LMM or middle-market data room in under 5 minutes with AI auto-indexing that organizes documents into a professional folder structure, NDA gates with built-in e-signatures, dynamic watermarks, page-level analytics, and screenshot protection on every plan.

3. Run a parallel pitch process with 3-5 advisors. Most Chicago sellers pick the first advisor who pitches well. The right approach is to run a 4-6 week parallel pitch with 3-5 firms (one Tier 4, two Tier 3, two Tier 2 if your deal is $25M-$150M EV; two Tier 4 and two Tier 3 if your deal is above $150M EV; two Tier 1 and two Tier 2 if your deal is sub-$25M EV). Compare track records in your specific sub-sector, ask for sample CIMs and data rooms from recent closes (not pitch decks), and verify the senior banker who will actually run your process.

4. Pre-clean the data room contents. Customer concentration tables, contract summaries, employee rosters with key person flags, AR aging by client, and AP aging by vendor should all be organized before the advisor sees them. Buyers will diligence all of this -- the question is whether they find it organized in week 1 or wait until week 8. For click-through NDA workflows that compress buyer onboarding from days to minutes, our M&A click-through NDA guide covers the full workflow.

For data room setup for M&A specifically, our M&A data room guide covers the 8-folder structure that Chicago advisors expect to see by week 1 of the engagement.

How Does Peony Help Chicago M&A Advisors and Their Sellers?

Peony is a data room platform built for the deal sizes that Chicago advisors actually close -- from $1M owner-operator exits up through $2B+ middle-market and upper middle-market transactions. The pricing and feature alignment matters:

• $40/admin/month for Business -- not $15K-$50K per deal like legacy VDRs that charge per-deal pricing
• 5-minute setup with AI auto-indexing -- organizes documents into the standard M&A folder structure automatically
• NDA gates with built-in e-signatures -- buyers sign once and access everything in a single workflow
• Dynamic watermarks -- viewer email and timestamp embedded in every rendered page
• Page-level analytics -- shows which buyers spent time on the QofE versus skimming the CIM
• Screenshot protection -- blocks and logs unauthorized capture attempts
• AI-powered Q&A -- handles repetitive buyer questions with cited answers from your uploaded documents
• Custom domain branding -- run your data room on a domain that matches your firm or transaction code name
• Unlimited data rooms -- no per-deal upcharges; a Chicago boutique running 12 deals per year pays the same flat $40/admin/month as a firm running 1 deal per year

A Chicago boutique advisor running 12 deals per year pays $480-$960 total on Peony versus $180K-$600K on legacy VDRs that charge $15K-$50K per deal. For sellers, the same data room transitions from the pitch process (sharing financials with 3-5 candidate Chicago advisors) to the actual buyer process (sharing the CIM and full data room with 50-300 prospective buyers) without rebuilding anything.

Set up your first Chicago M&A data room in under 5 minutes -- start free.

For solo M&A advisors and sub-LMM specialists running 1-3 deals per year, Peony Pro at $20/admin/month covers basic data room hosting with NDA gates, watermarks, and page-level analytics. The Business tier at $40/admin/month adds AI Smart Q&A, AI auto-indexing, screenshot protection, and unlimited data rooms -- which is what running middle-market and upper middle-market M&A processes actually requires.

Frequently Asked Questions

I'm selling a $25M industrial distribution business in Chicago. Lincoln International or PMCF?

For a $25M industrial distribution business, PMCF is the closer structural fit than Lincoln International. PMCF (Plante Moran Corporate Finance) sits in the $25M-$250M EV core middle-market band, runs a dedicated industrial distribution practice out of its Chicago office, and treats $25M deals as senior-banker-led engagements rather than rerouting them to associates. Lincoln International absolutely covers $25M, but as one of the largest dedicated middle-market M&A firms in the world (~1,400+ professionals across 25-30 offices globally) the firm's sweet spot starts higher around $75M-$150M EV. At $25M EV, you'll get a Lincoln vice president on most of your calls instead of the managing director who pitched the deal. PMCF, BGL Capital Partners, Livingstone Partners, and Peakstone Group are all better-aligned with the $25M-$50M EV industrial distribution band. Peony NDA-gated data rooms let founders share materials with three to five Chicago advisors during the pitch process so you can compare which team actually opens the CIM versus which one promised to.

What should I expect to pay an M&A advisor for a $50M ESOP transition in Chicago?

On a $50M ESOP transition in Chicago, expect total advisor fees in the 1.5%-3% range -- roughly $750K to $1.5M including retainer, success fee, and ESOP-specific work product (fairness opinion, valuation support, trustee coordination). Prairie Capital Advisors (Oakbrook Terrace, Illinois; founded 1996) is the dominant Chicago-area ESOP specialist with one of the deepest ESOP transaction track records in the country -- their fee structure is typically a Lehman-style success fee plus a flat fee for the ESOP-specific work. Mesirow Investment Banking, BGL Capital Partners, and Livingstone Partners also handle ESOP transitions but Prairie's specialization means tighter timelines and lower friction with the trustee community. Expect 25K to 100K retainer credited against the success fee, a 12-month exclusivity, and a 12-24 month tail period covering buyers introduced during the engagement. Peony page-level analytics show which prospective buyers are spending real time on the QofE versus skimming the CIM, which matters more on ESOP processes where buyer pool sizing is tighter than open-market sales.

My family business has been in Naperville since the 1960s. Who handles family-owned succession in Chicago?

For a multi-generational Naperville family business, the right Chicago advisors are the ones who understand both the financial mechanics of succession and the family dynamics that complicate it. PMCF (Plante Moran Corporate Finance) is the strongest single option -- the firm sits inside Plante Moran, the largest accounting and advisory firm in the Midwest, and the integrated tax and succession planning workflow is meaningful for family-owned sellers who need to coordinate the M&A transaction with estate planning, trust structures, and management equity rollovers. Prairie Capital Advisors handles family-owned ESOP transitions across the Chicago suburbs. Sun Acquisitions covers smaller family-owned Chicago businesses (sub-$10M EV) under President Domenic Rinaldi. Sikich Investment Banking and Livingstone Partners both run family-owned succession practices across the metro. Skolnik Industries to Pelican Energy Partners (December 31, 2024, Livingstone advised) is a representative example -- a family-owned Chicago industrial container manufacturer founded in 1928 that exited to Texas-based Pelican Energy Partners after multi-generational ownership. Peony NDA gates with embedded e-signatures let advisors filter buyer interest before sensitive family financials leave the data room.

I'm selling a $15M Chicago healthcare services business. Does Houlihan Lokey or Mesirow fit?

For a $15M Chicago healthcare services business, Mesirow Investment Banking is the better structural fit than Houlihan Lokey's Chicago office. Mesirow is a Chicago-headquartered firm with a dedicated middle-market healthcare services practice and treats $15M EV deals as core engagements rather than rerouting to a junior team. Houlihan Lokey is one of the most-respected middle-market firms globally and runs a serious healthcare practice, but at $15M EV you're at the bottom of the band where Houlihan accepts engagements -- you'll get a vice president running execution rather than the managing director who pitched the deal. BGL Capital Partners (Brown Gibbons Lang) and Peakstone Group both run dedicated Chicago healthcare services teams in the $25M-$150M EV range and are also worth pitching against Mesirow. For sub-$10M EV healthcare services, Sun Acquisitions, Ravinia Capital, and Origin Merchant Partners cover the smaller end of the Chicago healthcare market. Peony AI Q&A handles diligence questions like What is the payor mix or What is the patient retention rate with cited answers from your uploaded clinical and billing data, which is exactly the repetitive lift that healthcare buyers expect to see automated in 2026.

Why do Chicago industrials sell to PE rather than strategic buyers?

Chicago industrials sell to PE rather than strategic buyers because the structural buyer pool tilts that way. Three reasons. First, the Chicago metro hosts roughly 370,000 manufacturing jobs (about 9.4% of the metro's 4.71M-strong labor force), which makes Chicago one of the deepest industrial sub-markets in the United States -- and the PE platforms building roll-ups in industrial automation, specialty chemicals, food manufacturing, packaging, and industrial distribution all maintain Chicago coverage teams to scout deal flow. Second, Skolnik Industries to Pelican Energy Partners (December 31, 2024, family-owned industrial container manufacturer founded 1928 sold to Texas-based PE) and Specialty Bakers to HC Private Investments (June 24, 2025, food manufacturing platform sold to Chicago PE buyer) both followed the same pattern -- multi-generational family-owned industrial operators selling to PE platforms that promised continuity rather than to strategic acquirers who would absorb the operations. Third, Chicago industrial valuation multiples in 2025 ran 6x-9x EBITDA for non-specialty manufacturing and up to 12x EBITDA for specialty industrial niches, which PE platforms can pay because their model assumes operational improvement plus exit multiple expansion. Strategic buyers compete on the same multiples but tend to lose on continuity-of-employment commitments. Peony page-level analytics let advisors see which PE platforms are spending real time on the operational metrics versus the customer concentration tables.

How long does a Chicago M&A process take from engagement to close?

A Chicago M&A process in 2026 takes 6 to 9 months from engagement to close for a clean lower-middle-market or mid-market deal. The breakdown: weeks 1-4 for advisor preparation (CIM drafting, financial recasting, data room build), weeks 5-12 for buyer outreach (50-300 buyers contacted depending on advisor and sector), weeks 13-20 for management presentations and IOIs from interested parties, weeks 21-28 for LOI negotiation and exclusivity, and weeks 29-36 for confirmatory diligence and close. Tighter Chicago processes run 4-6 months when the seller arrives with audited financials, a complete data room, and a QofE already drafted before the engagement. Slower processes drag to 12+ months when the QofE turns up unexpected adjustments, customer concentration triggers retention earnouts, or the buyer pool requires re-marketing. Mid-market processes run by Lincoln International, William Blair, or Houlihan Lokey on $150M+ deals tend to compress slightly because the buyer universe is smaller and the firms run heavily structured timelines. Peony lets sellers and advisors set up a complete data room in under 5 minutes with AI auto-indexing, which compresses the front-end preparation timeline by 1-2 weeks compared to legacy VDRs that require manual folder structuring.

Can I avoid paying a Lehman scale on a sub-$10M deal?

On a sub-$10M Chicago deal, you generally cannot avoid the Lehman scale entirely, but you can negotiate a modified version that produces fairer economics for the deal size. The standard Lehman scale (5% on the first $1M, 4% on the second, 3% on the third, 2% on the fourth, 1% above) produces blended fees around 4-6% on sub-$10M transactions -- which sounds high but reflects the real cost of running a senior-banker-led process for a small deal. Sub-LMM Chicago firms like Sun Acquisitions, Ravinia Capital, Origin Merchant Partners, and Fultonbridge Partners typically use a modified Lehman or double-Lehman structure with a flat-fee component for sub-$5M deals. Some firms charge a flat sell-side fee in the $50K-$150K range plus a smaller success-fee tail. Avoid any advisor charging only an hourly rate on a sub-$10M deal -- the incentive alignment breaks down. Avoid any advisor demanding a $100K+ retainer on a sub-$5M deal where total fees should land at $400K-$600K. Peony Business at $40/admin/month means the data room cost on your sub-$10M deal is $40 not $15K-$50K like Datasite or Intralinks would charge per deal.

What's the difference between William Blair and Lincoln International for a $200M deal?

For a $200M deal, William Blair and Lincoln International are both strong fits but optimize for different seller profiles. William Blair is a Chicago-headquartered investment bank with a global growth-company focus, deep public-markets and ECM capability, and a healthcare and technology specialty that produces direct relationships with strategic acquirers and growth equity buyers. Lincoln International is a Chicago-headquartered middle-market specialist (~1,400+ professionals across 25-30 offices globally, founded 1996) that ranks among the top global middle-market M&A advisors -- the firm is structurally built for the $75M-$500M EV range. The split: William Blair wins when your buyer pool is heavily strategic acquirers, your business has growth-company characteristics (recurring revenue, vertical SaaS, scalable healthcare), or you might want public-market exit optionality. Lincoln wins when your buyer pool is heavily PE platforms, your business is a traditional middle-market industrial or services operator, and you want maximum buyer outreach depth across the global middle-market PE landscape. For a $200M Chicago industrial sale, Lincoln has the deeper PE platform Rolodex. For a $200M Chicago healthcare or vertical SaaS sale, William Blair has the deeper strategic-acquirer Rolodex. Peony AI Q&A handles diligence questions across both buyer profiles with cited answers from your uploaded financials.

Are Chicago M&A advisors competitive on cross-border deals?

Yes, on inbound cross-border deals into the Chicago market, the local boutiques are competitive. On outbound cross-border deals where the Chicago seller's buyer pool is heavily international, the answer depends on the advisor. Lincoln International (25-30 offices globally) and Houlihan Lokey (35+ offices globally) both run integrated cross-border practices that match the bulge-bracket banks on coverage breadth. William Blair maintains London, Frankfurt, Zurich, and Stockholm offices and runs a serious cross-border practice. Mesirow's cross-border reach is thinner. Below the top 4, the boutiques (BGL, Livingstone, Peakstone, PMCF, Dresner, Auctus) all have selective international relationships but are not structurally built for cross-border processes where 40%+ of the buyer pool is non-North American. For a Chicago founder running a deal where strategic Asian, European, or Middle Eastern buyers are likely lead bidders, hire Lincoln, Houlihan Lokey, or William Blair. For Chicago deals where 80%+ of the buyer pool is North American PE plus North American strategics, the boutiques are competitive on every dimension. Peony custom domain branding lets you run your data room on a domain that matches your firm or transaction code name -- which matters more on cross-border processes where buyers are unfamiliar with your brand.

Should I use a Chicago boutique or a New York investment bank for my $80M sale?

For an $80M Chicago sale, hire a Chicago boutique unless you have a clear strategic buyer in New York or San Francisco already at the table. The Chicago boutiques in the $80M EV band -- Lincoln International, William Blair, Houlihan Lokey (Chicago office), Mesirow Investment Banking, BGL Capital Partners, Livingstone Partners, Peakstone Group, PMCF, Dresner Partners -- run processes that match New York investment banks on every mechanical dimension (CIM quality, data room organization, buyer outreach depth, LOI negotiation discipline) and beat them on senior-banker engagement and fee economics. New York banks like Lazard, Evercore, or Moelis will accept an $80M engagement but route you to a vice president and two associates while the managing director who pitched the deal works on $500M-plus transactions. You pay 1.5-2% in fees for a New York brand and get a coverage team that is mid-market by their standards but lower-middle-market by yours. New York banks make sense for $300M-plus deals, public-market exit optionality, or cross-border processes where strategic Asian or European buyers are lead bidders. For a $80M Chicago lower-middle-market or mid-market sale to a North American PE platform or strategic acquirer, the Chicago boutique wins. Peony page-level analytics show which PE platforms and strategics are spending real time on the QofE versus skimming the CIM, which is exactly the kind of buyer-engagement intelligence that the Chicago senior banker actually uses.

Bottom Line

Chicago in 2026 is the deepest US lower-middle-market and middle-market boutique-advisor city outside New York, and arguably the most attractive for sellers in the $25M-$500M EV range. Illinois generates $913.7B in GDP, the metro's 4.71M-strong labor force is one of the most industrially-concentrated in the United States (370K manufacturing jobs, 9.4% of the labor force), and the 18 Chicago-headquartered or Chicago-led firms in this guide collectively close 1,500-2,500 transactions per year across the metro and broader Midwest.

For a $25M-$300M EV seller, the right Chicago advisor closes the deal in 4-6 months at fees that work for the deal size; the wrong choice (a New York bank running an $80M deal as a step-down engagement, an out-of-market firm with thin Chicago relationships, or a true business broker on a $25M deal) costs 6-12 extra months and produces uneconomic engagement terms.

Pick the tier that matches your deal size, run a parallel pitch with 3-5 firms, ask for sample CIMs and data rooms from recent closes (not pitch decks), and verify the senior banker who will actually run your process. Get the QofE done before signing the engagement letter. Build the data room before the advisor sees it.

When the engagement letter is signed, the right data room platform compresses the next 6 weeks of work into 5 minutes. Peony starts free, scales to $40/admin/month for full Business features, and replaces the $15K-$50K per-deal cost of legacy VDRs that price out the lower-middle-market.
