Donnelly Penman & Partners Research
Advisory Approach
Donnelly Penman & Partners is a FINRA-registered, middle-market investment banking firm based in Grosse Pointe Farms, Michigan with a sophisticated understanding of two distinct but deeply specialized sectors: automotive and financial institutions. The firm's thesis rests on industry-specific expertise combined with institutional-quality process management. Rather than positioning as a generalist bank, DPP has deliberately built two separate practices with dedicated teams, deep buyer networks, and decades of accumulated sector knowledge. This vertical focus enables the firm to understand nuances that generalist advisors miss — whether navigating automotive supply chain complexity or managing credit union/bank regulatory dynamics.
DPP's advisory positioning emphasizes transparency, data-driven decision making, and relationship-focused execution. The firm takes pride in being straightforward and credible with clients, providing proactive business strategy guidance grounded in real industry trends and market intelligence. Their approach balances financial engineering with operational understanding — particularly in automotive, where several managing directors have operational backgrounds and understand manufacturing economics.
Sector Focus
Automotive & Truck (Primary Practice): DPP specializes in serving Tier I and II automotive suppliers, specialty vehicle manufacturers, truck component producers, and aftermarket automotive companies. Within this space, they have deep expertise in precision machining, fluid handling components, transmission systems, aftermarket performance products, and timing drive systems. The firm understands the operational and financial complexities of automotive OEM relationships, supply chain economics, and the unique challenges facing family-owned component manufacturers navigating consolidation and private equity involvement. Recent transactions include the AMI Industries/Fluid Handling Technology deal (2024) and the Cloyes/Rotomaster combination (2023), demonstrating their ability to execute both seller-side and buyer-side advisory for mid-market automotive companies.
Financial Institutions (Primary Practice): DPP has built a substantial practice serving depository institutions (community banks, credit unions) and financial services companies. The firm advises on whole-bank acquisitions, purchase-and-assumption transactions, de novo bank formations, bank holding company structures, and recapitalizations. They understand regulatory approval processes, due diligence complexities, and post-close integration challenges specific to financial services. Recent activity includes the Zeal Credit Union/Gogebic Range Bank transaction (2024), DFCU Financial's Winter Park National Bank acquisition (2024-2025), Rio Bank/Lone Star Capital Bank merger (2025), and the GTSB Financial/First State Bank of Decatur transaction (2024). The firm's financial institutions team has closed numerous deals across depositories, mortgage banking, and other financial services verticals.
Deal Track Record
DPP has executed transactions across both sectors with a proven track record of closing complex deals. On the automotive side, the firm recently advised AMI Industries on the exclusive acquisition of Fluid Handling Technology from RB Holdings (July 2024), a fluid handling components supplier serving agriculture, construction, automotive, heavy truck, defense, and marine industries. The firm also provided commercial and financial advisory to Cloyes Gear & Products on its acquisition of Rotomaster, a global turbocharger and component specialist (October 2023). On the financial institutions side, the firm advised Beacon Credit Union on its purchase and assumption of Mid-Southern Savings Bank in southern Indiana (2024), representing Beacon's first community bank acquisition and expanding the combined organization to approximately $1.7 billion in assets. The firm also advised DFCU Financial on its acquisition of Winter Park National Bank in Florida (2024-2025), marking DFCU's third Florida transaction.
More recently, DPP advised Zeal Credit Union on its all-cash acquisition of Gogebic Range Bank, a $147 million asset community bank in Michigan's Upper Peninsula (2024-2025), and Rio Financial Services on the merger with Lone Star Capital Bank, creating a combined entity with approximately $1.43 billion in assets across Texas (2025). Additionally, the firm structured the capital raise and advised GTSB Financial on its acquisition of First State Bank of Decatur (Michigan's oldest chartered bank, founded 1870) in October 2024.
The firm has completed 28 cross-border transactions across 17 countries since 2000, demonstrating genuine international capability and buyer network reach that extends beyond North America.
Process & Fee Structure
DPP emphasizes institutional-quality processes with rigorous data management and buyer outreach. Engagements typically include comprehensive financial analysis, valuation work, management presentation coaching, and strategic buyer identification. The firm conducts thorough due diligence to support negotiations and has developed relationships with 2,000+ active financial buyers, PE firms, and strategic acquirers across both sectors. Process timelines typically range from 6-12 months depending on complexity and deal size.
The firm offers modified Lehman fee structures for M&A advisory engagements, with retainers likely required for larger transactions. Specific fee ranges are not publicly disclosed on their website.
Buyer Network
DPP's buyer network spans private equity firms, strategic acquirers, credit unions, and financial institutions. Recent deal activity shows relationships with firms like MidOcean Partners (Cloyes acquisition, co-advising with Stifel), Zeal Credit Union, DFCU Financial, Rio Bank, and strategic industrial buyers. The firm's 28 cross-border transactions indicate access to international PE and strategic buyer networks as well.
Competitive Positioning
DPP differentiates through specialized industry expertise, relationship depth in two chosen verticals, and operational understanding that informs advisory. The firm's founders have deep roots in both sectors and have built teams of bankers who understand automotive supply chains and financial institution operations at a sophisticated level. Unlike generalist regional banks that dabble across many sectors, DPP has concentrated its resources on automotive and financial institutions, enabling deeper market intelligence, stronger buyer relationships, and better strategic guidance.
Not a Fit If
Transactions outside automotive/truck and financial institutions sectors. DPP does not appear to actively pursue technology, healthcare, consumer, or industrial sectors outside automotive supply. Companies seeking a broad generalist firm with exposure to many industry groups.
Team
The firm operates with approximately 13+ senior bankers and analysts across two practices with experienced leadership holding CFA, CPA designations, and FINRA registrations including Series 79 and Series 63.
