Mike McTighe, group chairman of Together, said: “We maintained our strong growth momentum in the year while continuing to invest in our people, products, distribution channels, systems and governance.
“We also continued enhancing our senior management team with several senior appointments across the group, including the arrival of John Lowe from Coventry Building Society.
“We also added further depth and diversity to our funding structures, issuing our first public residential mortgage backed securitisation for £275m, upsizing our 2024 bonds with a successful £150m issuance, extending our £255m Lakeside securitisation on improved terms and launching our inaugural £525m Highfield warehouse facility for small balance commercial real estate. The group’s continued progress was reflected in rating upgrades from both S&P and Fitch.”
