Zip Co Ltd shares suffered their worst single-day decline in over two years, plummeting 34.4% to A$1.85 despite the buy-now-pay-later provider delivering record cash earnings and upgrading full-year guidance. This represents a stark reminder, if one were needed, that in growth stocks, the trajectory of profitability can matter more than absolute performance.
The Zip share price closed at A$1.85, it’s lowest level since May 2025, after the single-session decline wiped approximately A$500 million from the company’s market cap. The stock now trades more than 60% below its 52-week high, with the sell-off intensifying throughout the trading day as markets digested the implications of flattening profit growth despite strong top-line momentum.
The violent market reaction stands in sharp contrast to the headline numbers: Zip reported its strongest-ever half-year result by most conventional metrics, yet markets focused squarely on what the figures suggested about future earnings power rather than past achievements.
Financial Performance: Strong Growth, Narrowing Margins
Zip’s first-half FY26 results revealed a company firing on most cylinders operationally. Cash EBTDA surged 85.6% year-on-year to A$124.3 million, while total income climbed 29.2% to A$664 million. Total transaction volume reached A$8.4 billion, representing 34.1% growth, with the operating margin expanding to 18.7% from 13.0% in the prior corresponding period.

Active customer numbers grew 4.1% to 6.6 million, while the merchant network expanded 10.5% to 90,600 partners. Net bad debts remained disciplined at 1.7% of transaction volume, precisely in line with management targets and reflecting improved credit quality across the portfolio.
The company’s balance sheet strengthened materially, with A$239 million in available cash and liquidity as at December 31, 2025, following completion of a A$100 million on-market share buyback that returned capital to shareholders while signalling management confidence.
Geographic Performance: US Drives Growth
The United States emerged as Zip’s primary growth engine, delivering transaction volume growth of 44.7% to A$6.3 billion and revenue expansion of 47% to A$445 million. Active customers in the region increased 9.7% to 4.63 million, supported by new merchant partnerships and product innovations including the Pay-in-2 offering.
The US market now represents approximately 75% of Zip’s total transaction volume, up from roughly 70% in the prior period—a geographic shift that carries important margin implications given different competitive dynamics and customer economics between regions.
In Australia and New Zealand, the company’s home markets, revenue and receivables returned to growth following several quarters of deliberate portfolio optimisation. New feature launches and strategic platform integrations with major retailers contributed to renewed momentum in the region.
Reflecting the strategic importance of the US market, CEO Cynthia Scott announced plans to relocate to the United States during the second half of 2026, positioning senior leadership closer to the company’s largest growth opportunity.
The Margin Question: Why Markets Sold Off
Despite the impressive headline growth, three specific metrics triggered the market reassessment. First, Zip’s revenue margin declined to 7.9% from 8.2% in the previous period. Management attributed this compression to the higher US mix, where competitive dynamics and product mix yield lower take rates than in Australia.
Second, net bad debts edged slightly higher to 1.73% of transaction volume from previous levels, remaining within target ranges but moving in the wrong direction as markets sought evidence of operating leverage.
Third, and perhaps most critically, management guided that second-half cash EBTDA would be “broadly in line” with the first half’s A$124.3 million. This statement effectively capped full-year cash EBTDA at approximately A$250 million, strong in absolute terms, but representing a deceleration in the growth rate that had characterised recent quarters.
Markets interpreted this guidance as evidence that Zip’s path to sustained profitability may prove lumpier and more margin-constrained than previously anticipated, particularly as the company scales in the intensely competitive US market where players including Affirm, Klarna, and Afterpay compete for merchant relationships and consumer wallet share.
Upgraded Guidance Amid Tempered Expectations
Based on first-half performance, Zip upgraded its FY26 group operating margin expectation to above 18.0%, up from prior guidance, and lifted cash EBTDA as a percentage of transaction volume to above 1.4%. These upgrades reflect genuine operational progress and improved unit economics across the business.
However, the flat sequential profit guidance for the second half suggests that incremental transaction volume may be coming at lower marginal profitability, raising questions about whether Zip can simultaneously defend market share and expand margins in its core markets—a challenge facing the entire buy-now-pay-later sector as it matures.
The company faces the classic growth stock dilemma: invest aggressively for market share and accept near-term margin pressure, or optimise for profitability and risk ceding ground to competitors in a land-grab phase of market development.
What Happens Next
Zip now faces a critical test of execution through the second half of FY26. Markets will scrutinise whether the company can stabilise revenue margins while continuing to grow transaction volumes, particularly in the US market where competitive intensity remains elevated.
The relocation of CEO Cynthia Scott to the United States signals management’s commitment to the region, but also underscores the challenges of managing a geographically diverse business with different competitive dynamics and regulatory environments across markets.
Key metrics to watch include customer acquisition costs, repeat transaction rates, merchant retention, and any signs that revenue margins can stabilise or expand as scale benefits materialise. The company’s ability to grow active customers faster than 4.1% while maintaining credit quality will prove essential to the bull thesis.
Regulatory developments also warrant attention, as governments in Australia, the United Kingdom, and potentially the United States consider increased oversight of buy-now-pay-later providers, which could impact product design, customer eligibility, and unit economics.
Zip’s record first-half result demonstrates that the company has achieved genuine scale and profitability in the competitive buy-now-pay-later sector, but the market’s brutal reassessment reflects concerns that margin compression and moderating profit growth may constrain the path to sustained value creation. With shares now trading 60% below recent highs, the stock presents either a compelling entry point for believers in the long-term structural growth of point-of-sale financing, or a value trap if competitive dynamics prevent the margin expansion that growth stock valuations demand. The next two quarters could prove decisive in determining which scenario unfolds.
