Rhea-AI Filing Summary

Algorhythm Holdings, Inc. failed to make a $1,500,000 payment due under a $1,750,000 promissory note, triggering an event of default. The note was issued to SemiCab Inc. under an equity purchase agreement and required a $1,500,000 payment on May 2, 2026 and a $250,000 payment on November 2, 2026.

Because the initial payment was missed, the interest rate on that $1,500,000 increased from six percent per annum to a default rate of eight percent per annum. During the default, SemiCab may, by written notice, declare all outstanding amounts immediately due, although it has not exercised any remedies as of the report date.

Insights

Missed $1.5M note payment triggers default and higher interest costs.

Algorhythm Holdings, Inc. missed the $1,500,000 initial payment due May 2, 2026 on a $1,750,000 promissory note to SemiCab Inc. This non-payment constitutes an event of default and immediately raises the interest rate on that portion from six percent to eight percent annually.

The default also gives SemiCab the right, upon written notice, to accelerate all outstanding amounts, making the entire note immediately due. As of the report date, SemiCab has not exercised these rights or sought other legal remedies, so actual cash outflows and enforcement outcomes will depend on its future decisions.

promissory note financial

"On May 2, 2025, Algorhythm Holdings, Inc. issued a promissory note in the principal amount of $1,750,000"

A promissory note is a written IOU in which one party promises to pay a specific sum, often with interest, to another party by a set date or on demand. Investors care because it functions like a loan: it creates a legal claim on future cash flows, carries credit and timing risk, and can affect valuation or liquidity—think of it as a formal, tradable promise to be repaid that can be assessed like any other debt investment.

event of default financial

"The Company failed to make the Initial Payment on May 2, 2026, triggering an event of default under the Promissory Note."

An event of default is a specific breach of a loan or bond agreement—such as missed payments or breaking agreed rules—that gives lenders the legal right to act, for example by demanding immediate repayment, seizing collateral, or accelerating other obligations. For investors, it’s a red flag because it can sharply reduce a company’s ability to operate or raise money, like a car lender repossessing a vehicle after missed payments, and often leads to falling share or bond prices.

default rate financial

"the interest rate applicable to the Initial Payment increased from six percent per annum to the default rate of eight percent per annum."

Default rate is the percentage of loans, bonds, or borrowers that fail to make required payments or otherwise break their payment promise over a given time. Investors watch it because rising defaults signal higher credit risk, lower expected returns, and potential losses across a portfolio—much like a landlord losing rent from a growing share of tenants, which reduces income and can lower property value.

equity purchase agreement financial

"pursuant to an equity purchase agreement among the Company and its subsidiary and the Seller."

An equity purchase agreement is a legal contract that sets the terms for buying ownership shares in a company, including the number of shares, price, and any conditions that must be met before the sale closes. For investors it matters because it determines how much ownership and control they gain, how the company’s value and share count change, and what protections or obligations each side has—think of it as the detailed bill of sale and ground rules for a stock purchase.

acceleration financial

"the Seller has the right, upon written notice, to declare all outstanding amounts immediately due and payable."
