Once the acquisitions are complete, Camerons will have a total of 110 pubs in its retail group across the North of England.
The funding will also help the brewer release six new lines of beer creating six jobs over the next year at the Hartlepool plant.
John Foots, Camerons Brewery finance director, said: “Camerons is a pub group that is ambitious and innovative. We are grateful to HSBC for supporting us as we continue to grow.
“Not only did Tony Leech and Andy Parker support our investment in infrastructure and expansion, they understood our thinking.”
Tony Leech, HSBC area director for corporate banking in the North East, added: “The deal was led by HSBC’s Andy Parker who completed the transaction quickly and efficiently to help Camerons implement their growth strategy as soon as possible.
“Camerons has reported a 14% increase in profit for 2015 and firmly have their sights set on further growth.
“They are a great example of an SME which is thriving in the North East, and we look forward to supporting the growth of their estates in the future.”
The finance package was drawn from HSBC’s £8bn SME fund which dedicates £150m to the Tyne Tees region.
