Twilio (TWLO) Q3 2026 earnings review
Twilio raises its full-year plan as profit outpaces sales
Twilio's customer messaging and voice software kept growing fast while tighter cost control pushed profit margins higher. Sales from businesses owned a year ago, excluding mobile carrier fees passed to customers at cost, rose 16% and cleared the company's own 11% to 12% plan. Chief executive Khozema Shipchandler raised the full-year outlook for a third straight quarter, even though the new fourth-quarter plan again points to 11% to 12% underlying growth.
| Sales from businesses owned a year ago (ex carrier fee hikes) | +16% 11–12% planned; +17% last quarter |
|---|---|
| Operating income, excluding one-offs | $326M +39% from a year ago; 21% margin |
| Existing customer expansion rate (DBNE) | 114% 116% last quarter; 109% a year ago |
| Full-year underlying sales outlook | Raised to 15% up from 13–13.5% previously |
⚖️ Verdict: 🟢 Bullish
The story got better because Twilio held its 16% underlying growth rate through a tougher autumn comparison while gross profit excluding one-offs grew faster at 18%. That combination shows higher-margin products are driving the business and supports the $50 million raise to the full-year operating profit and cash flow plans. One caution: the existing customer expansion rate slipped two percentage points from last quarter to 114%, and the diluted share count rose despite higher buybacks.
The question now is whether the fourth-quarter slowdown in the plan is just management's usual caution or an early sign that artificial intelligence startup demand is cooling. Either Twilio beats its 11% to 12% underlying target by four points as it did this quarter, or tougher comparisons and slowing customer expansion pull growth down toward the low teens. Voice growth figures on the call and fourth-quarter expansion rates will tell.
🐂 Bull Case
Underlying Sales Cleared a Tougher Comparison
Twilio runs the software that sends text messages, makes phone calls and verifies users for businesses. Chief executive Khozema Shipchandler said “Q3 was a great quarter for Twilio, driven by disciplined execution and broad-based strength across our product portfolio”. Sales from businesses owned a year ago, which strip out acquisitions and mobile carrier fee hikes passed to customers at cost, grew 16% from a year ago.
That 16% rate beat the communications software group's 11% to 12% plan and nearly matched last quarter's 17% pace, even against a tougher comparison from last autumn's voice and software add-on surge. The press release did not update separate growth rates for voice, verification or self-serve channels. Even so, Twilio raised its full-year underlying sales growth plan to 15%, the third raise this year.
What to watch: voice and software add-on growth rates on the conference call and in the quarterly filing. Holding voice growth near 20% would show that artificial intelligence customer demand is not slowing as early startups mature.
Gross Profit Outpaced Underlying Sales Again
Mobile carriers charge fees to deliver business text messages, which Twilio calls application-to-person (A2P) fees and passes through to customers at zero profit. Those fee hikes added $53.1 million to revenue this quarter and pulled gross margin excluding one-offs down 0.9 percentage points from a year ago to 49.2%. That headline drop hides the real product mix.
Gross profit dollars excluding one-offs grew 18% from a year ago to $767.8 million, beating the 16% underlying sales growth rate for a second straight quarter. By our math, stripping the $53.1 million of pass-through carrier fee hikes out of revenue lifts gross margin excluding one-offs to 51.0%, up 0.8 percentage points from a year ago because higher-margin voice and software products grew faster than text messaging.
What to watch: fourth-quarter gross profit growth excluding one-offs against the 11% to 12% plan. Beating that range again would confirm that higher-margin software products still lead growth.
Lower Sales and Developer Costs Lifted Margin
Twilio is turning its revenue growth into operating profit by holding down payroll and overhead. Operating income excluding one-offs rose 39% from a year ago to $325.7 million, lifting the operating margin by 2.9 percentage points to 20.9% and beating the top of the company's plan by $30.7 million. Reported operating income more than tripled to $148.6 million.
- Sales and marketing costs: 13.9% of revenue, down 3.1 percentage points from a year ago
- Research and development costs: 18.0% of revenue, down 2.2 percentage points
- General and administrative overhead: 7.4% of revenue, down 1.0 percentage point
- Stock-based pay across all lines: 9.9% of revenue, down 2.3 percentage points
Every major expense line shrank as a share of sales, so the margin gain did not rely on cutting a single department. That operating discipline let management raise its full-year operating profit plan by $50 million at the middle of the range, to $1.195 billion.
What to watch: fourth-quarter operating margin excluding one-offs, where the outlook points to 19.1% at the middle of the range. A reading above 20% would show the fourth-quarter plan is cautious.
🐻 Bear Case
Existing Customer Spending Slowed From Last Quarter
Twilio tracks how much existing customers spend through its Dollar-Based Net Expansion Rate (DBNE), which compares a quarter's revenue from active accounts to what that same group spent a year earlier. A reading above 100% means returning customers bought more. This quarter DBNE printed at 114%, up from 109% a year ago but down from 116% in the second quarter.
That two-point drop from last quarter breaks a seven-quarter streak where the metric either rose or held steady. Part of the slowdown is mechanical, because Twilio leaves pass-through carrier fee hikes inside DBNE, and the third quarter lapped the start of last year's fee hikes ($20.2 million in the third quarter of 2025). The press release does not state how much DBNE grew without those fees.
What to watch: the fee-adjusted expansion rate on the conference call, and reported DBNE next quarter. A drop below 112% would show existing customers are slowing their usage growth beyond the fee comparison.
Unpaid Customer Bills Grew Faster Than Sales
Last quarter Twilio wrote off $32.8 million of prepaid network services after two telecom suppliers ran into financial trouble, and its charge for unpaid customer bills rose. In the third quarter, accounts receivable — bills customers have not yet paid — climbed to $755.0 million, up 18.6% from the end of December 2025, while third-quarter sales are up 14.2% over the fourth quarter of 2025.
Unpaid bills are taking cash and growing faster than the business. On the cash flow statement, the nine-month working-capital drain from receivables more than quadrupled to $133.4 million from $30.9 million a year ago, and the nine-month charge for doubtful customer accounts more than doubled to $15.1 million from $6.4 million. Passing higher carrier fees on to smaller business customers may be stretching collections.
What to watch: the allowance for doubtful accounts and prepaid network balances in the third-quarter filing. Another rise in bad-debt charges would show smaller customers are struggling to pay higher messaging bills.
Share Count Rose Even With More Buybacks
Twilio bought back $127.2 million of its own stock in the third quarter, nearly double the $66 million it spent in the second quarter, bringing nine-month repurchases to $448.3 million under its $2.0 billion programme. Management presents the buyback as a way to return cash and shrink the share count, but diluted shares rose anyway.
Weighted-average diluted shares climbed 1.6% from a year ago and 1.3% from last quarter to 161.7 million, and the fourth-quarter outlook builds in another step up to 163 million shares. Employee stock grants totaled $153.9 million this quarter ($432.3 million over nine months), and rising share prices push more employee options into the diluted count faster than buybacks remove them.
What to watch: fourth-quarter share repurchases against the $700 million left on the authorization. Unless Twilio spends more of its free cash flow on buybacks, rising share counts will keep trimming per-share profit growth.
Risks this quarter didn't answer
Chief executive Khozema Shipchandler said “Consumer AI has accelerated AI development, and its adoption demands fast, reliable infrastructure built for AI speed.” However, the earnings release gave no numbers on artificial intelligence revenue and left four standing concerns open until the call or filing.
- Artificial intelligence customer durability: the release does not state what share of sales comes from AI startups or their retention rate.
- Product and customer disclosure: Twilio no longer reports active customer counts or Segment business unit results, and the release omits voice and add-on growth rates.
- Rival bundling: whether AI model makers and customer-relationship software vendors are bundling their own voice and messaging tools cannot be tested from the release.
- Equity investment losses: Twilio booked another $25.5 million loss from its Syniverse stake ($77.1 million over nine months), which it strips out of profit excluding one-offs.
💲 Other KPIs
Free cash flow — operating cash left after capital spending and capitalized software — jumped 49.3% from a year ago, lifting the free cash flow margin by 5 percentage points to 23.7%. That follows margins of 19% in Q4, 9% in Q1 and 24% in Q2, and exceeds Q3 operating income excluding one-offs by $43.9 million.
By our math, cash and short-term marketable securities of $2,891.5 million minus $993.6 million of long-term debt leaves $1,897.9 million in net cash. That is up from $1,478.1 million at the end of December 2025 and $1,663.2 million in Q2, because nine-month operating cash flow of $914.8 million easily covered $448.3 million of share buybacks.
Headcount rose by 133 employees from last quarter, or 2.4%, and is up 1.5% from 5,541 a year ago. After trimming staff from 5,587 at year-end to 5,492 in the second quarter, the communications software provider returned to net hiring in Q3 while still cutting operating expenses as a share of revenue.
🔮 Guidance
Raised. The new fourth-quarter plan calls for 17% to 17.5% growth from a year ago (2.6% from Q3 at the middle of the range), sitting above what last quarter's full-year outlook left for Q4 as Q3 lapped last year's carrier fee hikes. Twilio beat its quarterly revenue midpoint in all eight of the last eight quarters, by an average of 4.3% over the last four; if the pattern holds, Q4 revenue would grow 22.2% by our math.
New. The plan points to 11.5% underlying sales growth at the middle of the range, down from 16% in the third quarter and 17% in the second. It is the exact same 11% to 12% range Twilio issued for the third quarter three months ago before delivering a 4.5-point beat, and fourth-quarter comparisons get tougher against last year's voice acceleration.
Raised. At the $305 million middle of the range, fourth-quarter operating profit excluding one-offs would grow 19.3% from a year ago but fall 6.4% from Q3, putting the operating margin at 19.1% versus 20.9% in Q3. By our math, the range sits above the $281.4 million to $301.4 million that last quarter's full-year plan left for the fourth quarter.
New. The plan calls for $1.505 at the middle of the range, up 13.2% from $1.33 a year ago but down 8.8% from $1.65 in Q3. The sequential drop reflects both the lower planned operating profit and a higher diluted share count of 163 million, up from 161.7 million in Q3.
Raised. Management lifted the full-year reported sales growth target by 1.75 percentage points from the prior middle of the range, matching the 20% growth rate delivered in the third quarter. It is the third consecutive quarterly raise to the full-year top-line outlook, following moves from 12% to 14.5% to 18.25%.
Raised. The full-year underlying sales growth target moved up 1.75 percentage points from the prior middle of the range. This is the third raise in three quarters — +1.5 points in Q1, +3.25 points in Q2, and +1.75 points in Q3 — and the year is easily achievable with nine-month underlying sales already running above 16%.
Raised. The middle of the range moved up $50 million to $1,195 million, or 29.3% growth from a year ago. It is the third raise this year following moves of +$40 million in Q1 and +$55 million in Q2, and sits just $35 million below the $1.23 billion floor Twilio previously set for 2027.
Raised. Management lifted the full-year cash flow target by $50 million at the middle of the range to $1,195 million, up 26.4% from 2025. With $854.6 million already generated in the first nine months, the outlook leaves $340.4 million for Q4 by our math, up 32.9% from a year ago and representing a 21.3% margin.
❓ Key Questions
How fast did voice and software add-ons grow in Q3?
Last quarter voice grew more than 20% and verification grew more than 30%, driving the margin mix shift. The press release did not update those product figures, which are needed to check whether artificial intelligence voice demand held up against tougher autumn comparisons.
How much did carrier fees add to the expansion rate?
The Dollar-Based Net Expansion Rate slipped from 116% in Q2 to 114% in Q3 as Twilio lapped last year's Verizon fee hike. Investors need the fee-adjusted number to know whether existing customer usage slowed or stayed near 111%.
Why did unpaid bills and bad-debt charges jump again?
Accounts receivable rose 18.6% over nine months and the bad-debt provision more than doubled to $15.1 million. Management has not said whether pass-through carrier fee hikes are straining smaller business customers or if specific large accounts are paying late.
Is the 2027 operating profit target now obsolete?
Twilio previously targeted at least $1.23 billion of operating income excluding one-offs for 2027. Raising the 2026 plan to $1.19–1.20 billion puts the company within 3% of that goal a year early, leaving the 2027 baseline stale.
