Exhibit 99.1

Rubicon Technology, Inc. to acquire Janel Group LLC

Bensenville, IL and New York, New York, August 20, 2025 / GLOBE NEWSWIRE / - Rubicon Technology, Inc. (OTCQB:RBCN) (“Rubicon”) and Janel Corporation (OTCQX:JANL) (“Janel Corp”) today announced that they have entered into a definitive merger agreement, pursuant to which Rubicon will acquire Janel Group LLC (“Janel Group”) with Janel Group becoming a wholly owned subsidiary of Rubicon and Janel Corp receiving shares of Rubicon common stock.

Janel Group, based in Garden City, New York, and originally founded in 1974, is a wholly owned subsidiary of Janel Corp. Janel Group had revenues of approximately $181.3 million and operating income of approximately $8.7 million for the 12-month period ended June 30, 2025. The company is a non-asset based, full-service provider of cargo transportation logistics management services. Its management team will remain in place as part of Rubicon.

The transaction allows Rubicon to acquire a profitable business and better access to capital. Janel Corp shareholders will benefit from its ownership of Rubicon.

The transaction, which was approved by the Rubicon board, including its independent directors, is subject to approval by the majority of Rubicon’s disinterested stockholders.

Additional Transaction Details

Janel Corp will sell all of the issued and outstanding equity of Janel Group to Rubicon in exchange for 7,000,000 shares of Rubicon common stock, at a value of $4.75 per share. Rubicon will assume approximately $23 million of Janel Group indebtedness and net working capital liabilities and gain access to a total of $35 million in borrowing capacity as part of a revolving credit facility under Janel Corp’s existing credit line.

Prior to this transaction, Janel Corp owned 1,108,000 shares of Rubicon common stock, representing approximately 46.6 percent of all outstanding Rubicon common stock. Following this transaction, Janel Corp will own approximately 86.5 percent of Rubicon’s common stock. Janel Corp and Rubicon will maintain the existing governance, nomination and voting agreement requiring review and approval by Rubicon’s independent directors of related party transactions between Rubicon and Janel Corp, and any of its affiliates, until such time that Janel Corp and/or its affiliates acquire more than 90 percent of Rubicon’s outstanding stock.

In order to protect Rubicon’s ability to utilize its net operating loss carryforwards, Rubicon had previously adopted a stockholder rights plan to limit the ability of any group or person to acquire 5% or more of Rubicon’s common stock (subject to certain exceptions, including acquisitions approved by its board) by any group or person. The board of Rubicon has determined that the transaction will not impair the Rubicon’s net loss carryforwards.

Rubicon shares will continue to be traded on the OTC market.

Contingent upon a successful Rubicon stockholder vote and consummation of the transaction, Janel Corp expects to make a tender offer for an additional 400,000 shares of Rubicon stock at $4.75 per share in cash upon which Janel Corp would own approximately 90.7% of Rubicon’s common stock outstanding.

The tender offer described in this announcement has not yet commenced.
