Is Group 1 Automotive (GPI) A Bargain Following Its Hennessy Deal And New Debt?

Listen to the news

Group 1 Automotive (GPI) is back in focus after closing a US$1.25b private placement of senior unsecured notes to help fund the planned Hennessy dealership acquisition and refinance its revolving credit facility.

Recent trading has been rough for Group 1 Automotive, with the share price down 6.43% over 30 days and 17.88% over 90 days. The year-to-date share price return is down 36.88% and the 1-year total shareholder return has declined 42.76%, hinting that investors are treating the Hennessy deal, the new debt and the fresh board voice from Conifer as a reset moment rather than a clear growth signal so far.

Spot potential rebound candidates alongside Group 1 Automotive by scanning our hand picked 30 high quality undervalued stocks, which combines compressed valuations with solid fundamentals.

Group 1 Automotive now appears to be a larger retailer with more debt on its balance sheet compared with a year ago. The question is whether its solid auto platform at US$247.79 a share still aligns with a fair price tag.

Most Popular Narrative: 9.9% Undervalued

On the most followed view, Group 1 Automotive screens as undervalued, with a fair value of $275 against the last close at $247.79. This puts the Hennessy deal and fresh leverage into sharp focus for anyone weighing the reset.

Growing adoption of electric vehicles combined with manufacturer-backed direct-to-consumer sales models is set to diminish the role and pricing power of traditional dealers. This means Group 1 Automotive faces muted new vehicle sales growth and a long-term squeeze on revenue and gross profit per unit, even as the company invests in EV sales infrastructure.

See why 1 investors see Group 1 Automotive as 10% undervalued.

The most followed narrative uses a 12.54% discount rate and assumes revenue growth of about 2.7% a year, with profit margins moving from 1.3% to 2.8%, to reach earnings of $674.2m by around 2029 and justify a fair value of $275 at a P/E of 5.5x in that scenario.

That path reflects a view that Group 1 Automotive can grow earnings from a lower margin base while still being priced at a lower multiple than the wider US Specialty Retail group. This is even as the business leans on acquisitions, cost cuts and service operations to support its profit profile.

Result: Fair Value of $275 (UNDERVALUED)

Still, if Group 1 Automotive continues to integrate acquisitions such as Hennessy smoothly and maintains tight capital discipline, the bearish valuation case may weaken.
