Key Highlights

● Revenue rose and a small GAAP profit was reported

● Annual Revenue and Operating Income outlook raised

● New repurchase program approved

● Gross Margin and retention slipped slightly

Klaviyo, Inc. (NYSE:KVYO), a Marketing software company within the technology stocks universe, reported that revenue for the September quarter increased from the prior-year quarter, and it raised its revenue guidance for the full year. The company, listed on the New York Stock Exchange, also said its board had authorized a new program to repurchase Series A common stock. That authorization follows the completion in October of an earlier and larger repurchase program, according to the release's market data text.

The company describes itself as an autonomous CRM for consumer businesses, serving paying customers across a platform with a broad set of integrations. The update arrived at a moment of transition, with a new finance chief in place and a recently launched agent product line. Its headline message combined faster growth among larger accounts with heavier use of multiple products.

Co-founder and Co-Chief Executive Andrew Bialecki said in the release that "AI is taking barriers out of marketing" and that agents are taking on more of the work. Chief Financial Officer Erica Smith called the period "another strong quarter" with solid profitability, and said she has "deep conviction in the runway ahead" as the company scales profitably.

A Thin GAAP Profit and a Wider Non-GAAP Margin

Revenue grew by about a quarter from the year-earlier period. Market data, in an article, said revenue and Earnings Per Share were ahead of its consensus estimates for the period. Revenue also exceeded the top of the range management gave in August, according to a published the market transcript of the second-quarter call, which carries that publisher's standard notice about the use of Large Language Models.

GAAP results improved modestly. The operating loss narrowed from the prior-year quarter, and the company recorded a small GAAP net profit compared with a small net loss a year earlier. GAAP earnings per share rounded to nil in both periods, indicating how near to break-even the company remains on that measure.

Non-GAAP operating income rose from the prior-year quarter, while the non-GAAP Operating Margin edged up only slightly. Non-GAAP earnings per share also increased. The non-GAAP figures therefore show a Business growing its dollar profit largely in line with its revenue, with limited margin expansion for the period.

Gross margin moved in the other direction. Both GAAP and non-GAAP gross margin declined by more than a point from the prior year, even though Gross Profit grew in dollar terms.

Cash Flow Softens as Repurchases Absorb Liquidity

Cash metrics were less favourable than the profit lines. Operating Cash Flow slipped slightly from the prior-year quarter, and free cash flow declined by a much wider margin. The release's Cash Flow Statement also shows an outlay for the Acquisition of intangible assets, though it provides no further description of that item in the portion reviewed.

The largest movement came from Capital returns. The company made a sizeable payment for share repurchases during the third quarter, compared with no such payments in the same quarter a year earlier. Period-end cash, cash equivalents and restricted cash were well below the prior-year level, and total stockholders' Equity fell compared with December.

Those figures provide context for the buyback story. On the second-quarter call, then-Chief Financial Officer Amanda Whalen said the company had used a large sum to repurchase shares during that quarter and still had capacity remaining under the program announced in March, adding that it expected to keep buying while citing an attractive valuation. The release now says the program was completed in October. Across a short span, the company has thus returned a substantial amount of capital while also growing its operations.

Whether and how quickly that capacity gets used remains an open question, particularly with cash below the level of a year earlier.

Deferred revenue offered a firmer reading, rising from the level recorded at the end of December, according to the Balance Sheet in the release. On the August call, Fernandez Gomez also described the largest omnichannel deal in the company's history, a multi-year agreement, as having closed in the second quarter.

Larger Accounts Lead the Growth

The most striking trend in the release was the performance of larger customers. Accounts generating annual Recurring Revenue above each of the thresholds the company tracks grew much faster than the customer base overall, and the growth rate increased at each higher tier. In practical terms, the largest cohorts are expanding the most rapidly, although they remain small in number compared with the wider base.

According to market data, the count of customers above the lowest of those thresholds was slightly ahead of its consensus estimate. On the second-quarter call, Co-Chief Executive Luciano Fernandez Gomez said this group already represented a large share of total annual recurring revenue, a measure of how much weight the segment carries. A year ago, the published the market transcript of the third-quarter call in the previous year showed management framing mid-market and enterprise momentum as one of its growth engines.

The release names Frasers Group, Malbon Golf and Voluspa as examples of new wins and expansions. Total customers rose, moving up from the level Bialecki cited in August and substantially ahead of the count reported a year earlier. According to market data, the reported customer total came in marginally below its consensus estimate, so overall customer growth and enterprise momentum did not read identically against expectations.

Retention Slips While Multi-Product Use Deepens

Net revenue retention came in slightly lower than the level reported on the August call and in the year-ago period, and Market commentary said it fell just below its consensus estimate. The release defines the metric as a comparison of the annual recurring revenue of customers active a year earlier with what those same customers generate now. It includes expansion, price increases and reactivations, reflects contraction and attrition, and excludes new customers. The figure is a weighted average of monthly readings over the trailing year, so it moves gradually.

Whalen explained some of the dynamics on the August call. She attributed retention at that time to stronger gross retention and text expansion, offset by lapping the prior year's profile enforcement, and said the impact of that enforcement would continue into the first quarter of next year because the metric is measured on a trailing basis.

Other indicators pointed towards deeper product adoption. The share of annual recurring revenue from customers using multiple products rose compared with the near-fifth level Fernandez Gomez cited in August. He said at the time that customers using multiple products retain meaningfully better on gross retention than single-product customers, which helps explain why the company highlights this measure so prominently.

International Demand Keeps Outpacing the Whole

Revenue outside the Americas grew by about a third, according to the release, faster than total company revenue. The pace was a little below the rate Fernandez Gomez cited for the second quarter, when he also reported especially strong growth in the European, Middle Eastern and African region outside the UK.

International expansion has been a stated priority for some time. Bialecki said in August that the company aims for most revenue to come from outside North America over time. The forward-looking section of the November release lists sustaining international growth among its risks, along with Macroeconomic Factors including tariffs, which underscores that the company itself treats this growth as not assured.

The Shopify (NASDAQ:SHOP) relationship and other platform connections remain relevant here, given the company's focus on merchants. The release said the company launched embedded apps, Klaviyo in Shopify and Klaviyo in Wix, which bring Klaviyo and Composer directly into the merchant experience. The risks section also refers to the importance of integration with third-party platforms and relationships with partners, making distribution through these ecosystems a recurring theme.

Composer and the Agent Strategy

Product news in the release concentrated on AI. The company released a new version of Composer that it described as more autonomous, proactive and trusted, with connectors, skills and artifacts. It also announced Klaviyo Headless, which lets customers access Klaviyo data from AI systems including Claude and ChatGPT, a step that opens the platform to tools outside its own interface.

Composer was still new at the time of the August call. According to that transcript, Bialecki said it had attracted a large number of users during its first month after launch, with meaningful uptake among mid-market and enterprise customers. It is priced on credits, and customers received a trial allotment for experimentation. The Customer Agent product is priced per autonomously resolved conversation, and Bialecki said adoption had grown strongly from the prior quarter.

Bialecki laid out the direction in August by saying, "Every business will have an agent that decides, delivers and autonomously optimizes the experiences their customers have." The company also acquired Agency, which brought Elias Torres on as chief product officer with the goal of moving faster on agents, Bialecki said on that call.

Klaviyo also said it was recognized in analyst evaluations, including the Gartner Magic Quadrant for Multichannel Marketing Hubs. No other evaluation was named in the release.

Bialecki also used the August call to pitch scale as an advantage, saying the platform can personalize a very large Volume of messages in a short window. The company's argument rests on pairing its data infrastructure with AI agents, a positioning repeated in the description of an autonomous CRM.

Guidance Moves Higher on Both Revenue and Profit

The full-year revenue guidance range moved above the range given in August, with the low end of the new range exceeding the top of the old one. Implied growth for the year is about a quarter, a notch higher than the rate discussed in August. The fourth-quarter range implies growth of about a fifth, slower than the third-quarter pace and a further deceleration on the headline measure.

Non-GAAP operating income guidance for the year was also lifted, and by a noticeable margin compared with the range set in August. That earlier range had been reduced at the time, with Whalen saying the cut included costs related to the Agency acquisition.

Fourth-quarter non-GAAP operating income guidance sits above the third-quarter figure in dollar terms. The fully diluted share count assumed for the fourth quarter is below the count assumed for the full year, consistent with the repurchases made during the year.

Limits of the Available Evidence

Market reaction to the release could not be established from an opened source. The results came out, with the conference call following shortly after. An article from According to market data, the shares had risen substantially during the past month, while its S&P 500 comparison showed a small decline in the same period, but it did not give a post-earnings move.

Similarly, sections of the third-quarter call were not available from any transcript that could be accessed, which limits the discussion of management's explanations for gross margin, retention and free cash flow.

The Leadership change adds another variable worth noting. Whalen stepped down following the August call and stayed on in an advisory role through November, with Smith becoming chief financial officer at the start of September, according to the second-quarter transcript.

A broader assessment rests on how the items in the release develop: whether larger accounts continue to expand at their current pace, whether retention stabilizes as the profile enforcement effect passes, how much revenue the agent products contribute, and how the new repurchase authorization is used against a lower cash balance. The company's forward-looking statements caution that its ability to sustain growth, attract mid-market and enterprise customers and use AI effectively are all subject to risks and uncertainties.
