According to a recent update thread on the Secure Boot Objects GitHub, MS deliberately rotates through a series of one-year "leaf" certs to sign the boot manager. And this particular one will be the last in that series, since they can't generate another past the Oct 2026 deadline.
After that, presumably they'll switch a new round of one-year certs after October.
