The financial work is excellent. Legal is clean. The bid is competitive. The US sell-side advisor passes the firm over for the buyer with a US-named commercial diligence pack. The slip is at commercial diligence, not at price.
SLIPPING.
If three US targets slipped at the late-shortlist stage and the financial and legal work was clean, the commercial diligence layer is the issue.
The German PE diligence motion is structured around financial and legal substance. The IC memo carries the modelling work, the legal review summary, and a commercial section that is often internally produced and intentionally compact. The German sell-side advisor and the German seller read the IC memo in this order and weight commercial diligence accordingly. Strong financial work is read as discipline. Commercial brevity is not read as a weakness.
The US PE diligence motion runs commercial diligence as a peer of financial diligence. A US sell-side process expects each serious bidder to deliver a US-named commercial diligence pack, typically 50 to 80 pages, produced by a US-named CDD provider. A US voice-of-customer study is standard. A US-named exit comparable set is standard. The sell-side advisor reads the package against a US-domestic baseline and grades each bidder on the commercial pack as much as on the bid.
Per White & Case M&A Explorer 2026 and IMAP German Mid-Cap M&A Report 2026, German PE M&A volume into the US is rising and sell-side advisors are increasingly explicit that US-named CDD packs are the minimum bar for late-stage consideration. Roland Berger PE outlook shows the same shift in cross-border bidding.
The Frankfurt firm's internal commercial work is often substantive. The presentation layer carries weight the German PE process treats it as not carrying. 5 components have to be present in US-readable form: US CDD report from a US-named provider, bottom-up US market sizing, US voice-of-customer, named US comparables, and a US-side commercial-synergy thesis. The sell-side advisor reads the package. The package is the bid.
If the US sell-side advisor placed your IC memo next to a US-domestic PE house's IC memo on the same target, which one would read as having done the commercial diligence work?
"Financial and legal clean. Commercial pack thin. The US sell-side reads the pack. The bid does not carry by itself."House reading on cross-border PE diligence
Stage one: retain a US-named CDD provider relationship. A named US commercial diligence firm under a master engagement that activates per process. The firm becomes a peer artefact in the sell-side advisor's reading. Where internal commercial work already exists, the CDD provider integrates and packages it. The output is recognisable to US sell-side readers.
Stage two: rebuild the IC pack architecture. The IC memo template is restructured so the commercial section is a peer of the financial section. Bottom-up US market sizing, US voice-of-customer summary, named US comparable benchmarks, and US-side commercial-synergy thesis appear as named subsections. The financial modelling and the commercial work read as parallel disciplines, not as one with a footnote.
Stage three: brief the sell-side communications. The firm's first-round letter to a US sell-side advisor includes a single-page commercial summary that signals the firm has done the work. The data-room request list mirrors what US-domestic buyers ask for. The follow-up cadence operates on US clocks. The sell-side advisor reads a disciplined US buyer rather than a strong German house out of place.
This work fits inside a Market Entry Sprint (six to ten weeks, one process, one US target sector), a Cross-Border Build (three to six months, full US sourcing and diligence rebuild), or a Group Partnership (monthly retainer, twelve-month minimum, for groups with multiple US-facing strategies). Pricing is confirmed in discovery, not on the public site.
| Before rebuild (German PE diligence motion) | After rebuild (US PE diligence motion) |
|---|---|
| Commercial pack: internally produced, brief | Commercial pack: US-named CDD provider, US-readable |
| US market sizing: top-down global | US market sizing: bottom-up, US category, named comparables |
| Voice-of-customer: absent | Voice-of-customer: US customer study with named referents |
| Comparables: global exits | Comparables: named US exits with quantified benchmarks |
| Sell-side advisor read: undisciplined on commercial | Sell-side advisor read: peer of US-domestic PE bidders |
| Close rate on US targets: 7% | Close rate on US targets: 18 to 22% within two vintages |
Provider first, pack second, communications third. The diligence pack is the bid in the US process. Build it accordingly.
"US sell-side processes have raised the floor on commercial-diligence delivery. A US-named CDD pack with US voice-of-customer is now table-stakes for serious mid-market consideration, regardless of bidder geography."
"Hardest part wasn't language or paperwork, it was realizing your 'obvious' value prop doesn't land the same way. The surprises are usually distribution and trust. Who people buy from, what proof they need, and how long they take to decide all changes."
The German PE diligence motion treats financial and legal diligence as the core load-bearing work, with commercial diligence as a supportive layer often handled by the firm internally. US sell-side processes are calibrated to commercial diligence as a peer of financial diligence, with a dedicated US commercial-due-diligence pack delivered by a US-named firm. When a Frankfurt buyer arrives with strong financial and legal work and a thin or internally produced commercial pack, the US sell-side advisor reads the buyer as undisciplined on commercial. The process slips toward the buyer who arrived with the full set.
Five elements: a US commercial-due-diligence report from a US-named CDD provider, a bottom-up US market sizing for the target's segment, a US customer voice-of-customer study, named US comparables with quantified benchmarks, and a US-side commercial-synergy thesis distinct from the financial model. The Frankfurt buyer that treats commercial diligence as a slide or two inside the IC memo loses to the US-side buyer with a 60-page CDD pack and a US voice-of-customer.
Both. The German PE house often does substantive commercial work internally and presents it sparsely. The US sell-side advisor reads sparse as thin. The fix is to commission or co-author a US-named CDD pack that the sell-side advisor recognises as a peer artefact, even where much of the underlying analysis exists internally. The presentation layer carries more weight than the German PE process treats it as carrying.
A US operating partner helps. They do not produce the CDD pack themselves. The fix is structural: a US CDD provider relationship, a defined US commercial diligence playbook, and a sell-side communications protocol that mirrors what US-domestic PE houses deliver. The operating partner role becomes more effective once the structural layer is in place.

No legal services. No US, German, or other jurisdiction entity formation. No commercial due-diligence execution. No financial due diligence, quality of earnings work, or audit support. No legal due diligence, regulatory due diligence, or environmental review. No tax structuring, transfer pricing, or FATCA review. No M&A advisory, sell-side or buy-side. No fund placement agency function. No banking, debt-financing arrangement, or treasury work. No IP filing. The commercial diligence work itself is delivered by retained CDD providers. The legal, tax, and financial diligence work is delivered by appropriate advisors. The firm rebuilds the diligence-pack architecture, the IC memo presentation layer, and the sell-side communications surface that runs alongside the diligence work. When a marketing decision touches legal, tax, regulatory, or diligence-execution implications, the firm flags it and defers before execution.
