From SEC filings: the results press release (8-K) or, without one, the quarterly or annual report.
KIRA Β· Ribbon Communications Inc. had $845M of revenue in fiscal 2025, up 1.3% on the year before. Over five years, revenue changed +0.0% a year on average. Its operating margin was β0.4%, down 2.4Β pts: of every 100 in sales, about β0 is left after running the business.
In plain words: Revenue is all the money customers paid. The margins show how many cents of each dollar of sales are left over at each step: after making the product (gross), after running the business (operating) and after everything, tax included (net).
KIRA Β· Ribbon Communications Inc. made $39.6M of net profit in fiscal 2025.
Loss periods are shown in red.
In plain words: Net income is the profit left after every cost and tax. Earnings per share (EPS) splits that profit across every share, so it shows what one share earned.
How much cash comes in, and where does it go?
KIRA Β· Free cash flow was $26.1M in fiscal 2025, 3.1% of revenue.
Cash from operations minus capital spending.
In plain words: Profit on paper is not the same as cash in the bank. Free cash flow is the cash left after paying to run and maintain the business: the money it can hand back to shareholders, save or invest.
KIRA Β· Ribbon Communications Inc. returned $9.0M to shareholders in fiscal 2025, 34% of free cash flow. The diluted share count rose 3.3%.
In plain words: Companies hand cash back in two ways: dividends (cash paid to shareholders) and buybacks (buying back their own shares, so each remaining share owns a bigger slice).
KIRA Β· No open-market insider trades in the last 12 months.
Open-market purchases and sales by officers, directors and 10% owners, from Form 4 filings. βPlanβ marks trades under a pre-arranged Rule 10b5-1 plan.
In plain words: Insiders are the people who run or own a big part of the company. Buying with their own money can signal confidence; selling often has personal reasons, like taxes or diversifying.

Can it carry its debts, and how well does it use its money?
KIRA Β· Ribbon Communications Inc. owes $246M more than it holds in cash, about 18.3 years of operating profit.
Cash, debt and the ratios that show how comfortably Ribbon Communications Inc. can carry it.
In plain words: What the company owns and what it owes. More cash than debt is a cushion for bad times; a lot of debt leaves less room when business slows down.

KIRA Β· Its return on capital was β0.4%: every 100 invested in the business earned about β0 in a year.
After-tax operating income as a share of the money invested in the business: debt plus equity, minus cash.
In plain words: How much profit the business makes on the money put into it. A higher percentage means each dollar invested works harder.
KIRA Β· Ribbon Communications Inc. passes 6 of 9 financial health tests (Piotroski F-score).
Nine pass/fail tests of profitability, funding and efficiency. 8β9 is strong, 0β2 weak.
In plain words: Nine yes/no tests of financial health, one point each. A green tick is a pass: 7 to 9 points is solid, 0 to 3 is weak.
