LightStream to Carlyle: working backwards to the deal math

$7.7B of prime personal loans sold for roughly 93.5 cents. Using only public disclosures, here is what the price implies about losses, duration and Carlyle's return, and why Truist was willing to take it.

Truist is selling its LightStream portfolio to Carlyle: $7.7B of prime unsecured personal loans for roughly $7.2B in net proceeds, or about 93.5 cents on the dollar. LightStream has also stopped taking new applications.

A price on a loan book is a compressed statement about three things: how much the loans will lose, how long they will be outstanding, and what return the buyer needs. If you know the price and can pin down two of the three, the third falls out. Here is that exercise using only public information.

What the pool looks like

Working backwards from public disclosures, the pool implies:

  • Annual loss rate of ~3–3.5%. This is prime/super-prime unsecured credit, so losses well below the broader personal loan market.
  • About 2 years of remaining life. Personal loans amortize, and prime borrowers prepay, so the weighted-average life of a seasoned book is far shorter than its stated terms.
  • An average coupon of ~10%.

The buyer's return

Take the pieces in turn, per year, on a rough unlevered basis:

Component Approx. annual contribution
Coupon ~10%
Less: credit losses ~(3–3.5%)
Plus: discount accretion (6.5 pts spread over ~2 years) ~3%+
Unlevered return, before servicing ~10–11%

The discount does a lot of the work. Buying at 93.5 on a two-year asset adds roughly three points a year on top of the net coupon. Then add leverage: prime consumer loans finance well in warehouse and ABS markets. For Carlyle, that is a good deal.

Why sell?

For Truist the logic is about capital, not credit. The sale frees up about 20 bps of CET1, roughly $850M, which can be redeployed into fee-generating businesses that the market values more highly than a spread-lending book.

The hidden cost is what Truist spent building the book. Acquiring prime personal loan borrowers is expensive. I would estimate 2–3% of loan amount went into acquisition along the way. LightStream also famously charges no origination fee, so nothing offset that cost upfront. Selling at a discount means part of that acquisition investment never gets earned back.

What it means for the market

A few takeaways for lenders and capital providers in personal loans:

  1. Price discovery is rare, and this deal is one. Public whole-loan sales of prime unsecured paper at this size don't happen often. A clean mark in the low-to-mid 90s for a seasoned prime book is a useful reference for anyone negotiating forward-flow or valuing a portfolio.
  2. Speed and relationships matter. A book this size, sold quickly, favors buyers who already hold financing and servicing arrangements and can sign without months of diligence.
  3. Rates matter more than this one sale. A single sale doesn't move the market's credit box. Funding costs and the shape of the curve do far more to set where lenders price and whom they approve.

I discussed the transaction in more depth on the Free Toaster News Pod (#34) with Carlos Caro and Nick Madrid, including who else probably bid and how much of the $50K–$100K super-prime segment LightStream likely held.
