What Mitek Systems, Inc. told the SEC could break it.

Mitek depends on a relatively small number of customers — a single customer accounted for 15% of total revenue ($26.9M) in fiscal 2025 (the same customer was 17% in 2024 and 16% in 2023) — and it expects to keep depending on a few customers for a significant portion of revenue; loss of, or a changed relationship with, that key customer would cause a significant revenue decline. (Customer not named, so recorded as concentration risk.)

“For the twelve months ended September 30, 2025, the Company derived revenue of $26.9 million from one customer, with such customer accounting for 15% of the Company's total revenue.”

Mitek issued 2026 convertible senior notes (net proceeds ~$149.7M) with an initial conversion price of ~$20.85 per share; the convertible feature is dilutive to EPS when the average stock price exceeds the conversion price, and the notes' approaching maturity creates refinancing/repayment exposure that depends on market conditions and the company's cash position.

“The conversion rate for the 2026 Notes will initially be 47.9731 shares of the Common Stock per $1,000 principal amount of 2026 Notes, which is equivalent to an initial conversion price of approximately $20.85 per share of the Common Stock.”

Mitek derives substantially all of its revenue from a few types of technologies — mobile check-deposit (Mobile Deposit) and digital identity/fraud-prevention products (Mobile Verify, Check Fraud Defender, HooYu/MiVIP) — so if these technologies and related products fail to achieve or sustain market acceptance, or compatibility with customer platforms erodes, its business and results would be materially harmed (legacy identity-verification product sales already declined in 2025).

“We currently derive substantially all of our revenue from a few types of technologies. If these technologies and the related products do not achieve or continue to achieve market acceptance, our business, financial condition, and results of operations would be adversely affected.”

Because AI, automated decision-making and machine-learning technologies are core to Mitek's biometric identity-verification and fraud products, increased regulation — particularly the EU AI Act — could complicate compliance and raise costs, and its use of third-party AI models triggers IP, contractual and export-control considerations; as a global operator it is also subject to anti-corruption (FCPA), data-privacy and trade-protection laws, non-compliance with which could bring fines and sanctions.

“Given that AI, automated decision making and ML technologies are core to our business, any increased regulation over these technologies, including the EU AI Act, could make it harder for us to conduct our business, significantly complicate our compliance efforts, incre”
