It's a bit tricky to express succinctly in English. The first part is quite clear, and the figure in brackets shows the change over the period (so the previous period must have had an operating profit of ¥0.7bn, ７億円). 「赤字転落」 means that it fell from a profit to a loss. The 「同」 means 'in the same terms' referring back to earlier in the passage, so I would imagine it means 'year-on-year' if this is about annual results (but it might be quarter-on-quarter, depending on the preceding context). Having 赤字転落 means you can't use a word like 'fell' because you have a profit in one period and a loss in the next.
