You could store intermediate CompletableFuture in a variable and then use thenCombine:

CompletableFuture futureA = CompletableFuture.supplyAsync(...)
    .thenApply(...)
    .thenApply(...);

CompletableFuture futureB = futureA.thenApply(...);

CompletableFuture futureC = futureA.thenCombine(futureB, service::methodE);

objC = futureC.join();
