The employee-owned firm, which operates Waitrose and the department store chain, will provide its next update in September and will no longer break down the revenues and profits of each brand.
The partnership has been combining the executive teams behind John Lewis and Waitrose into one team.
It recently reported a fall in sales over the Christmas period and raised doubts over whether it will pay a staff bonus.
Retail group John Lewis Partnership has warned its staff bonus may be in doubt for a second year in a row as it reported a fall in festive sales at its department store chain.
It warned that annual profits might not be enough for it to pay out any bonus.
The board will meet in February to decide if it is "prudent" to pay the staff bonus, it said.
John Lewis owns department store John Lewis & Partners and supermarket group Waitrose.
It is a partnership that is owned by its staff and the bonus has been paid since 1953.
Two months later, it cut the bonus to the lowest since the 1950s after a plunge in profits.
'Barely any signs of growth' for John Lewis

Even Edgar the dragon couldn't fire up John Lewis's Christmas sales
It appears that John Lewis's issues are more at the department store chain as opposed to Waitrose.
It said it expects annual profits at Waitrose "to be broadly in line with last
year".
While the firm expects John Lewis to reverse losses incurred in the
first half of the year, it said "profits will be substantially down on last year".
"We
therefore expect that partnership profit before exceptionals will be
significantly lower than last year."
For the seven weeks to 4 January, the partnership said gross sales fell 1.8% to £2.1bn and pointed to a bumpy period which included the Black Friday promotional event.
"We saw
significant variation in levels of demand with Black Friday sales up 10.0% on
the equivalent period last year, followed by more subdued demand in the
subsequent weeks," it said.
Meanwhile, online sales for John Lewis rose just 1.4%.
Retail Economics chief executive Richard Lim, says: "Excitable Edgar did little to fire up Christmas sales with declines
across non-food and a woeful performance in the online business which barely
showed any signs of growth."
