Bandwidth Inc (BAND) Earnings: Q3 2026 Results

The quarter ended September 30, 2026 and Bandwidth published the results on October 29, 2026. Revenue and diluted EPS are shown against Q3 2025, the same quarter a year earlier, which takes seasonal swings out of the comparison. Bandwidth reports EPS two ways: GAAP, under the accounting rules every US filer follows, and non-GAAP, which leaves out items the company considers outside its operating results. The release reconciles the two, and when they diverge, the reconciliation says why.

• Messaging surcharges are fees Bandwidth collects and passes through to carriers. Bandwidth calculates its non-GAAP gross margin and adjusted EBITDA margin on cloud communications revenue, which excludes them.
• The revenue split above is from the Q3 2026 Form 10-Q; the release reports total revenue only.

How Bandwidth splits revenue in its own release, under its own labels, for Q3 2026 against Q3 2025. Indented lines are parts of the line above them.

• Bandwidth's Cloud communications revenue was $158 million in Q3 2026, up 12% from $142 million in Q3 2025, 68% of total revenue.
• Bandwidth's Messaging surcharges revenue was $75.6 million in Q3 2026, up 51% from $50.1 million in Q3 2025, 32% of total revenue.

Segment lines are the figures writers cite most often, because they show where the growth in a quarter came from. Companies redraw their segments from time to time and restate the prior year to match, so a year-ago figure here can differ from the one printed a year ago. When that has happened, the note above says so.

We do not hold a confirmed date for Bandwidth's next report. Companies post the date on their investor relations site a few weeks ahead, usually with the time of the conference call.

Each quarter keeps its own page with the figures as reported, so a link to one stays pointed at the same numbers after the next report.

• Q3 2026 (this page), reported Oct 29, 2026

Bandwidth had revenue of $234.0 million in Q3 2026, up 22% from $191.9 million a year earlier. Its 10-Q splits that into cloud communications revenue of $158.5 million, up 12%, and messaging surcharges of $75.6 million, up 51%. The surcharges are carrier fees passed through to customers, and Bandwidth said they rose with higher messaging activity and increased carrier surcharges. (Bandwidth Form 10-Q, Q3 2026, Oct 29, 2026)

Bandwidth sells voice calling, text messaging and emergency services through three market offerings. Global Voice Plans powers UCaaS and CCaaS providers including Microsoft, Google, Zoom, Cisco, RingCentral, Genesys and Five9; the other two are Programmable Messaging and Enterprise Voice. Most of its revenue comes from usage-based fees. (Bandwidth Form 10-K, 2025, Feb 19, 2026)

Within cloud communications revenue, Bandwidth's Global Voice Plans revenue grew 8% on higher voice traffic, Enterprise Voice grew 15%, and Programmable Messaging grew 26%. The messaging figure included about $3 million of political campaign messaging ahead of the November 2026 U.S. midterm elections, which Bandwidth does not expect to recur in 2027. (Bandwidth Form 10-Q, Q3 2026, Oct 29, 2026)

Bandwidth's revenue is mostly domestic: $207.2 million came from the United States and $26.9 million from international destinations in Q3 2026, and no country outside the United States reached 10% of revenue. Average annual customer revenue was $0.3 million, up 18%. The 10-K warns that a significant portion of revenue is concentrated among a limited number of large customers. (Bandwidth Form 10-Q, Q3 2026, Oct 29, 2026; Bandwidth Form 10-K, 2025, Feb 19, 2026)

Bandwidth earned GAAP net income of $5.2 million, or $0.13 per diluted share, in Q3 2026, against a net loss of $1.2 million, or $(0.04), a year earlier. Non-GAAP net income was $19.9 million, or $0.50 per share. The adjustments add back stock-based compensation and related payroll taxes of $14.6 million and amortization of acquired intangibles of $7.5 million, remove an $800 thousand net gain on extinguishment of debt, and deduct estimated tax effects of $7.2 million. (Bandwidth Q3 2026 release (8-K Exhibit 99.1), Oct 29, 2026)

Bandwidth's GAAP diluted share count of 40,134,189 includes 4,433,843 shares from convertible debt conversion. In 2026 it issued 2032 Convertible Notes, retired the 2026 notes and repurchased 2028 notes. It also bought back 225,343 Class A shares in Q3 at an average price of $44.20, for $10 million, with about $50 million left under its $80 million program. (Bandwidth Q3 2026 release (8-K Exhibit 99.1), Oct 29, 2026; Bandwidth Form 10-Q, Q3 2026, Oct 29, 2026)

Bandwidth's GAAP gross margin fell to 36% from 38%, partly because amortization of acquired intangibles in cost of revenue rose from $2 million to $5 million. Bandwidth shortened the remaining useful life of developed technology acquired in 2020 from five years to two because customers are migrating faster to its Universal Platform. (Bandwidth Form 10-Q, Q3 2026, Oct 29, 2026)

Diluted EPS divides net income by the weighted average number of shares outstanding in the quarter, plus the shares that options and other equity awards could add. Buybacks shrink that count and lift EPS for the same profit; share issuance and stock awards enlarge it.

Bandwidth gives a full-year outlook in its release. For 2026 it guides revenue of $905 million to $910 million, adjusted EBITDA of $124 million to $125 million and non-GAAP EPS of $1.73 to $1.79, assuming about 38.7 million weighted average diluted shares. It does not reconcile these to GAAP because stock-based compensation cannot be reasonably predicted. (Bandwidth Q3 2026 release (8-K Exhibit 99.1), Oct 29, 2026)

The release headline also gives a first look at 2027: double-digit growth in cloud communications revenue from voice usage demand. Bandwidth has said the roughly $3 million of Q3 political messaging revenue is not expected to recur in 2027.

A consensus figure is the average of the models published by the analysts who cover Bandwidth, collected by a data provider and revised up to the day of the report. A quarter that lands above it says how expectations were set as much as how the business did, and the share price on the day also reflects the guidance and the lines no consensus covers.

The consensus figures on this page are Yahoo Finance's, as pulled on the date shown. Each comes with the number of analysts behind it; the smaller that number, the more one revised estimate can move the average.

The figures below are the ones Bandwidth's own release and filings put weight on for Q3 2026, with the latest reported value for each.

What the quarter means for a holding is a separate question from what it reported. The case for and against owning BAND is on is BAND a buy or a sell?, what analysts expect next is on the BAND forecast, and what the company does is on the Bandwidth Inc (BAND) stock page.

Every number on this page can be traced to a document Bandwidth published. Checking one takes a couple of minutes, and it is worth doing before you quote a figure anywhere.

• The results release is the document linked in the source line above. Companies publish it on their investor relations site at the moment results go out, and it carries the headline tables: revenue, operating income, net income and EPS for the quarter and the year-ago quarter.
• The same release is filed with the SEC as Exhibit 99.1 to a Form 8-K under Item 2.02, usually on the day of the report. The SEC copy does not change after the fact, which makes it the safer thing to link when you cite a number.
• The quarterly report (Form 10-Q) follows within a few weeks and carries the full financial statements, the segment note and management's discussion of what changed. The fourth quarter is covered by the annual report (Form 10-K) instead.
• Restated comparisons are flagged in the notes on this page. When a company redraws its segments or changes how it adjusts EPS, it restates the year-ago column, so the year-ago figure in a new release can differ from the one printed a year ago. This page always uses the comparison in the newer release, because that is the like-for-like one.
