Current report

During February 2026, our board of directors authorized a share repurchase program to repurchase up to $80.0 million in aggregate value of our Class A common stock, subject to market conditions, contractual restrictions and other factors. The repurchases may be made from time to time at the discretion of management through open market purchases, block trades, privately negotiated transactions, Rule 10b5-1 plans or other means.

Current report

During the three months ended March 31, 2026, we repurchased 313,936 shares of our Class A common stock at an average price of $15.93 per share, excluding commissions, for an aggregate purchase price of $5 million. As of March 31, 2026, approximately $75 million remained available for repurchases under the share repurchase program.

Current report

On March 1, 2026, the 2026 Convertible Notes matured and the related 2026 Capped Calls expired. The aggregate remaining outstanding principal amount of$7.6 million of 2026 Convertible Notes, along with all accrued and unpaid interest, was settled in full in cash. As of March 31, 2026, no 2026 Convertible Notes remain outstanding.

Current report

For the three months ended March 31, 2026 and 2025, our effective tax rate was (58.9)% and 1.8%, respectively. For the three months ended March 31, 2026 and 2025, our income tax benefit was$2 million and less than $1 million, respectively. The increase in tax benefit is primarily due to favorable U.S. federal and state tax law changes as a result of the One Big Beautiful Bill Act (“OBBBA”).

Current report

For the three months ended March 31, 2026, net cash used in financing activities was$60 million, driven primarily by$100 million used to complete the 2026 Repurchases and $11 million used for tax withholdings on vested employee awards and share repurchases under the share repurchase program. These cash outflows were partially offset by $51 million of cash from borrowings under our Credit Facility to fund the 2026 Repurchases.
Removed paragraphs (17)

Previous report

Our effective tax rate was 64.8% and 228.7% for the three months ended September 30, 2025 and 2024, respectively, and 18.3% and 21.0% for the nine months ended September 30, 2025 and 2024, respectively. The decrease in the effective tax rate from 2024 to 2025 is primarily due to an increased operating loss in the U.S. This increased operating loss did not result in a corresponding increase to income tax benefit because the related deferred tax assets are subject to a valuation allowance. In periods in which we are in a pre-tax loss position, a decrease in the effective tax rate is considered unfavorable, as it indicates that a smaller portion of the pre-tax loss is recognized as an income tax benefit. The unfavorable change in the effective tax rate is partially offset by favorable U.S. income tax law changes under the One Big Beautiful Bill Act (“OBBBA”).

Previous report

For the three months ended September 30, 2025, general and administrative expenses increased by$1 million, or 3%, compared with the same period in 2024, driven by higher non-headcount expenses in connection with maintaining and enhancing day-to-day business support activities.

Previous report

Most of the permanent tax adjustments within our effective tax rate are offset by a valuation allowance. These adjustments include state taxes, federal research tax credits under Section 41 of the Code, equity compensation in the U.S. and other non-deductible expenditures in the U.S. Excluding the impact of the valuation allowance, we realized an estimated state effective tax rateof 4.3% for the three months ended September 30, 2025. In addition, exclusive of the valuation allowance, we continue to generate income tax benefits in the current period related to income tax credits recognized for qualified research activities in the U.S. The applicable federal tax laws and regulations define qualified research activities as research and development activities conducted in the U.S. that involve a process of experimentation designed to discover new information intended to develop a new or improved business component. Absent the valuation allowance, equity compensation also impacts the effective tax rate to the extent the income tax deduction exceeds or is below the related book expense, as required under ASC 718-740-35-2. Other U.S. non-deductible expenses that are offset by the valuation allowance consist primarily of non-deductible executive compensation under Section 162(m) of the Code.

Previous report

Permanent tax adjustments within our effective tax rate that are not offset by the valuation allowance include federal and state tax payables, foreign tax benefits and foreign rate differentials. As we continue to scale our international business, any changes to foreign business activity may impact our effective tax rate in the future.

For the nine months ended September 30, 2025, net cash provided by operating activities was$51 million and was generated by our aggregate results of $70 million during the period, net of (1) non-cash items comprising depreciation and amortization, non-cash reduction to the right-of-use asset, amortization of debt discount and issuance costs, stock-based compensation, deferred taxes and other, net gain on extinguishment of debt and (2) a$19 million cash outflow from lower operating liabilities and higher operating assets. Within operating liabilities, the net cash used as a result of lower accrued expenses and other liabilities of $13 million during the nine months ended September 30, 2025, was primarily driven by the timing of payments. Within operating assets, the net cash used as a result of higher accounts receivable of$6 million during thenine months ended September 30, 2025, was driven by higher unbilled receivables balances arising from higher usage amounts in the last month of the quarter ended September 30, 2025.

Current wording

For the three months ended March 31, 2026, net cash provided by operating activities was$9 million and was generated by our aggregate results of $26 million during the period, net of (1) non-cash items comprising depreciation and amortization, non-cash reduction to the right-of-use asset, amortization of debt discount and issuance costs, stock-based compensation, deferred taxes and other, net gain on extinguishment of debt and (2) a$18 million cash outflow, primarily from lower operating liabilities and higher operating assets. Within operating liabilities, net cash used of $4 million was driven by $9 million of outflows from decreases in accounts payable, partially offset by $7 million of cash generated by increases in accrued expenses and other liabilities. The increase in accrued expenses and other liabilities was largely driven by the timing of payments and correlated with higher network usage. Within operating assets, the net cash used of $14 million was primarily driven by higher unbilled receivables balances of $10 million from higher usage amounts in the last month of the quarter ended March 31, 2026 and changes in prepaid expenses and other current assets of$4 million.

For the nine months ended September 30, 2025, our average annual customer revenue was$0.2 million, which increased less than $0.1 million compared with the same period in 2024, as a result of our strategy to attract and retain larger customers who provide revenue scale and enhanced profitability.

Previous report — wording carried elsewhere

For the nine months ended September 30, 2025, total cost of revenue decreased by$6 million compared with the same period in 2024, driven by lower messaging cost of revenue of$10 million from less political messaging following the 2024 U.S. presidential election. Thecombination of changes in total revenue and total cost of revenue yielded an increase in total gross profit of$14 million, or 7%, from the same period in 2024, driven byongoing efficiencies and improved unit economics as we successfully scale larger volumes of voice traffic on our network.

For the nine months ended September 30, 2025, we recognized an income tax benefit of$2 million, an increase of $1 million, compared with the same period in 2024. The resulting effective tax rate for thenine months ended September 30, 2025 was 18.3%, compared with 21.0% in 2024. The increase in income tax benefit was primarily due to a$2 million benefit recognized as a result of the favorable tax law changes enacted under OBBBA.

Previous report — wording carried elsewhere

For the nine months ended September 30, 2025, the effective tax rate of 18.3% differed from the federal statutory rate of 21% in the U.S. primarily due to the valuation allowance recorded against our U.S. federal and state net deferred tax assets.

Previous report — wording carried elsewhere

We continue to expect recurring changes to the valuation allowance as deferred tax assets within the U.S. increase or decrease in subsequent periods. We will maintain a valuation allowance against all U.S. federal and state deferred tax assets until it becomes more likely than not that the benefit of our federal and state deferred tax assets will be realized.
