Shawbrook Announces Strategic Acquisition of ThinCats to Enhance SME Lending Portfolio

Shawbrook buys ThinCats: doubling down on bespoke SME lending

Shawbrook Group plc has signed an agreement to acquire ThinCats Group Limited, a specialist lender focused on providing bespoke funding to established, growth-focused SMEs. The ThinCats brand will sit within Shawbrook’s portfolio and continue to serve owner-managed and sponsor-backed businesses with event-driven finance.

The message is clear: Shawbrook is leaning into specialist SME lending, using tech, data and a relationship-led model to scale. Completion is expected later in 2025.

What Shawbrook is buying: ThinCats in a nutshell

ThinCats brings an established market position, strong origination capability, and a streamlined, technology-enabled platform. It also arrives with a projected loan book of c.£0.7 billion on completion and corresponding risk weighted assets (RWAs) of c.£0.6 billion.

In plain English: Shawbrook is buying a platform that’s already good at finding and structuring SME loans, running on modern tech, and plugged into adviser and sponsor networks. Shawbrook plans to keep the ThinCats brand and scale it using the Group’s distribution, investment, and funding structure.

Why this deal matters: accelerating SME lending growth

Shawbrook’s SME segment accounted for c.21% of the Group’s total loan book as at 30 June 2025. Activity is up, with both new lending and pipeline volumes exceeding those in the first half of 2024. This acquisition is designed to accelerate that trend.

Crucially, both CEOs emphasise alignment: technology-led underwriting, credit discipline, and a relationship model built for complex, event-driven funding needs. That’s where specialist lenders earn their keep – structuring the nuanced deals that mainstream banks often decline or take too long to approve.

Key numbers investors should note

Projected ThinCats loan book on completion	c.£0.7 billion
Projected ThinCats risk weighted assets (RWAs)	c.£0.6 billion
EPS impact	Expected to be accretive in first full financial year post completion
Return on invested capital	Described as “highly attractive”
SME share of Shawbrook loan book (30 June 2025)	c.21% (based on net loan book)
Shawbrook net loan book (footnote)	£15.8 billion
Adjusted loan book incl. derecognised structured asset sales (footnote)	£17.0 billion
Goodwill from transaction (footnote)	Immaterial single digit £m (subject to final purchase price allocation)
Completion timing	Expected later in 2025

Financial impact: capital, earnings and goodwill

Shawbrook expects the transaction to be EPS accretive in the first full financial year after completion. That’s the headline most equity investors care about: the deal should lift earnings rather than dilute them.

The RNS also flags c.£0.6 billion of RWAs. RWAs are the risk-weighted amount of assets that determine how much regulatory capital a bank must hold. More RWAs generally mean more capital consumption, so the EPS accretion implies the returns from the acquired book and platform are expected to more than cover the cost of funding and capital.

Goodwill is described as “immaterial single digit £m”. That suggests limited intangible uplift on acquisition, which is usually positive for capital ratios because there’s less to deduct from regulatory capital.

Strategic fit: tech-enabled SME lending at scale

Shawbrook highlights a strong strategic alignment: both businesses use technology and data to streamline underwriting, backed by relationship-led coverage for complex SME needs. ThinCats’ streamlined tech stack “complements” Shawbrook’s platform, and the distribution network and origination engine are already in place.

The Group’s originate-to-distribute model (noted in the loan book footnote) shows Shawbrook is comfortable originating assets and selling them into structured formats where appropriate. ThinCats’ origination capability could slot neatly into that playbook, helping Shawbrook recycle capital and scale without ballooning the on-balance-sheet loan book.

What’s good, what’s less good

Positives

• EPS accretive and “highly attractive” return on invested capital expected.
• Brings c.£0.7 billion of specialist SME lending with strong origination and distribution.
• Immaterial goodwill points to limited capital drag from intangibles.
• Brand retained and scaled via Shawbrook’s platform, funding and channels.
• Builds on rising SME activity, with new lending and pipeline ahead of H1 2024.

Watch-outs

• Purchase price and detailed financial terms are not disclosed.
• Capital impact beyond RWAs not disclosed; no CET1 ratio guidance.
• Credit quality metrics for the ThinCats book are not disclosed.
• Integration risk always exists when combining platforms and teams.

What isn’t disclosed

The RNS does not disclose the purchase price, expected cost synergies, revenue synergies, funding cost changes, or any regulatory approvals or conditions. There’s also no detail on ThinCats’ NIM (net interest margin), impairment trends, arrears, or sector mix, which would help investors assess risk and return in more detail.

Why it matters for shareholders

Shawbrook is leaning into a large, growing niche where it already has traction. If management executes, this deal should add scale, origination capacity and technology leverage to a part of the Group delivering momentum.

The combination of EPS accretion, limited goodwill and a clear strategic fit is encouraging. The key is whether returns remain robust once capital usage (c.£0.6 billion RWAs) and any integration costs are fully absorbed. Without a disclosed price, investors will want to see the post-completion numbers to validate the “highly attractive” ROIC claim.

What to watch next

• Completion timing and any regulatory or closing conditions as we move through 2025.
• Updated guidance on capital ratios and funding mix after ThinCats is consolidated.
• Proof of EPS accretion in the first full year post completion.
• Trends in SME originations, pricing and credit performance across the combined platform.

Bottom line

This is a strategic bolt-on that plays to Shawbrook’s strengths: tech-enabled, relationship-led SME lending. The ThinCats platform looks additive, the goodwill is small, and management is guiding to EPS accretion.

We still need the price tag and fuller financials, but on the face of it, Shawbrook is buying growth in a market where it already competes well – and doing so in a way that should scale efficiently across its platform.
