Summary

  • Green Dot's B2B gross dollar volume reached US$42.253 billion in fiscal Q2 2026, up 22.0% year on year. Active accounts rose 9.4% to 1.98 million, while reported purchase volume increased 1.3% to US$2.025 billion.
  • Gross dollar volume measures funds loaded onto account products. Purchase volume excludes ATM withdrawals and also excludes transactions in certain BaaS programmes where the partner receives interchange and Green Dot earns a programme-management fee. The figures cannot be divided into a conversion rate.
  • B2B revenue rose 28.6% to US$448.435 million, but expense rose 29.7% to US$415.996 million. Processing expense increased 35.9%, and the calculated segment-profit margin fell from about 8.0% to 7.2%.
  • The proposed separation would place the non-bank FinTech business with Smith Ventures and Green Dot Bank with CommerceOne, with the bank becoming the FinTech business's exclusive sponsor. The missing contract terms will determine how volume, cost and regulatory control are shared after closing.

The same dollar can pass through several commercial ledgers

Green Dot's fastest-growing B2B number is not card spending. Gross dollar volume, or GDV, is the amount loaded to account products through direct-deposit and non-direct-deposit sources. In the three months ended 30 June 2026, B2B GDV rose by US$7.633 billion to US$42.253 billion. That is a 22.0% increase.

Reported purchase volume moved much less. It reached US$2.025 billion, only US$25 million or 1.3% above the prior-year quarter. It would be tempting to subtract one balance from the other or divide purchases by loaded funds. Both operations would manufacture a result that Green Dot does not report.

Purchase volume measures purchase transactions by accountholders, but excludes ATM withdrawals. More importantly for BaaS, it excludes volume generated by certain programmes where the partner receives interchange fees and Green Dot earns a programme-management service fee. Funds can therefore enter Green Dot-powered accounts, be used through a partner-controlled card arrangement and never enter Green Dot's reported purchase-volume denominator.

GDV is also not a period-end deposit balance. Money can arrive and leave within the quarter through purchases, cash, transfers and other routes. Nor is it Green Dot revenue. It is an operating flow that can support several revenue contracts. The useful question is not how much of US$42.253 billion was “converted”. It is which party monetised each route and which cost followed it.

More volume per account does not guarantee more interchange

B2B active accounts rose from 1.81 million to 1.98 million, a 9.4% increase. GDV grew more than twice as quickly. Green Dot says growth from new and existing users was concentrated in certain BaaS programmes that tend to produce higher GDV per active user but do not generate comparable interchange fees for Green Dot.

That statement changes the economic reading. A traditional card model may link account activity, purchases and interchange with a reasonably visible sequence. A BaaS contract can redirect the payment-rail economics. The partner may receive interchange while Green Dot earns a fee for programme management, account infrastructure, processing or access to its regulated bank platform.

Green Dot says the higher GDV produced more B2B revenue through programme-management fees. B2B segment revenue rose US$99.785 million, or 28.6%, to US$448.435 million. The company also says a significant BaaS partner led revenue growth and that the rest of the BaaS channel recorded its strongest growth in more than a year.

The filing does not name the significant partner in this disclosure or publish its GDV, fee schedule, deposits, interchange, processing cost or contribution profit. It would be wrong to turn a disclosed concentration of growth into an invented contract waterfall. The evidence establishes the monetisation form, not its unit price.

Processing cost nearly matched the revenue increase

The volume carried a large direct cost. B2B processing expense rose from US$273.434 million to US$371.667 million, an increase of US$98.233 million or 35.9%. Green Dot describes this expense as payment-network fees, third-party processor fees and fees paid to banks that issue or process accounts. These costs generally vary with active accounts and GDV.

B2B total expense consequently increased 29.7% to US$415.996 million, slightly faster than revenue. Segment profit still rose, but by a slower 15.9%, from US$27.980 million to US$32.439 million. Calculated from the reported figures, segment-profit margin fell from about 8.0% to 7.2%.

The earnings release supplies the qualitative bridge: BaaS margins declined modestly because of revenue mix, particularly growth at a significant partner. That does not mean the partner is unprofitable. Segment profit increased. It means a dollar of reported B2B revenue did not carry the same incremental margin across programmes.

The Q1 filing gives the structural reason. Green Dot said certain BaaS partnerships are largely arranged on a fixed-profit basis, so profit for those arrangements will not scale with revenue. Fixed-profit can still be rational if it brings durable deposits, lowers acquisition risk or creates follow-on services. It also means GDV and revenue can grow rapidly without proportional profit expansion.

The divergence persisted for two quarters

This was not a one-quarter measurement accident. In fiscal Q1 2026, B2B GDV rose 19.2% year on year to US$39.338 billion while purchase volume fell 3%. Green Dot used the same explanation: growth centred on BaaS programmes that did not generate comparable interchange for Green Dot and instead produced management fees.

Sequentially, Q2 B2B GDV increased US$2.915 billion from Q1. Active accounts rose from 1.91 million to 1.98 million, and purchase volume rose from US$1.917 billion to US$2.025 billion. These figures show continuing activity, but they do not reveal customer cohorts or seasonally adjusted conversion.

The persistence matters because it shifts the monitoring object from a surprising quarter to a changing revenue mix. If excluded partner-controlled purchase activity keeps growing, Green Dot's reported purchase volume will become a less complete description of activity across the BaaS estate. It can remain valid for its defined purpose—analysing Green Dot interchange—while becoming less suitable as a shorthand for total end-user use.

That is a disclosure problem of resolution, not an allegation of faulty reporting. Green Dot states the exclusion. The next useful table would add the excluded purchase volume, programme-management fees and processing cost by major contract family without compromising partner confidentiality.

Consolidated interchange fell for a broader reason

Across Green Dot as a whole, interchange revenue fell 5.9% to US$44.186 million. The company attributes the decline to a 6% decrease in consolidated purchase volume while its effective interchange rate remained consistent. Consumer Services purchase volume fell 10.4%, and Consumer active accounts fell 12.0%.

Those figures prevent a second false inference. The fall in consolidated interchange cannot be assigned entirely to B2B contract mix. Green Dot's legacy consumer account base was shrinking at the same time. Consumer revenue fell 9%, with lower monthly maintenance, ATM and interchange fees partly offset by expanded overdraft usage.

The group therefore held two different account economies. B2B GDV and management-fee revenue expanded through partners. Direct consumer activity and fee pools contracted. A consolidated revenue line can net those movements without showing which customer relationship is gaining control over distribution.

Total operating revenue rose 18.2% to US$595.883 million, but operating expense rose 21.6% to US$596.644 million. The quarter produced a US$2.087 million GAAP net loss. Adjusted EBITDA fell 12% to US$40.176 million, although the company says tax-revenue timing and Consumer headwinds also affected that comparison. The BaaS mix is one operating mechanism, not a complete explanation of consolidated profit.

The sponsor-bank contract will become the control surface

Green Dot is preparing to divide the integrated institution reflected in these accounts. Under announced agreements, Smith Ventures would acquire and privatise the non-bank FinTech operations. CommerceOne would acquire Green Dot Bank and its associated operations. The combined bank would then serve as the FinTech business's exclusive sponsor bank.

The transactions had received shareholder approval and early termination of the US antitrust waiting period, but still required regulatory approvals and other closing conditions at the date of the Q2 release. They are proposed, not completed. Green Dot did not issue 2026 guidance or hold an earnings call because of the pending transactions.

Today, Green Dot can show bank interest, partner interest sharing, programme fees, processing costs and unallocated corporate costs inside one consolidated perimeter. After separation, some of those economic transfers can become contracts between independently owned parties. The price of bank sponsorship, allocation of compliance work, capital requirements, data access, service levels, loss responsibility and termination rights will determine whether the current BaaS economics survive.

Exclusivity can stabilise the operating chain: the FinTech business knows which bank supports its programmes, and the bank receives a committed distribution partner. It can also create bilateral dependence. If one side underinvests in compliance, technology or account operations, the other cannot switch instantly without customer migration and regulatory work.

What US$42.253 billion actually proves

The constructive reading is specific. Green Dot attracted substantially more funds into B2B account programmes, increased active accounts, grew management-fee revenue and still increased segment profit. Its BaaS platform is carrying more activity even as the direct consumer franchise contracts.

The demanding reading is equally specific. Reported purchase volume does not cover all programme spending, processing costs grew faster than B2B revenue, calculated margin compressed, and a significant partner shaped the mix. The pending separation will move critical economics into an exclusive sponsor-bank relationship whose detailed terms are not public.

Neither reading supports a conversion-rate story. GDV, counted purchases, partner interchange, programme fees, processing cost and deposit income are separate receipts. Green Dot's quarter matters because it exposes the architecture: growth is real, but the party paid for that growth depends on the contract.
