13-10-2026

CID HoldCo, Inc. (doing business as Dot Ai, Nasdaq: DAIC) completed the acquisition of Envoy Technologies, Inc. from BladeRanger Ltd. in an all-stock transaction valued at approximately $65 million at a $6.00 per share reference price. The deal adds an established, revenue-generating EV carsharing business, but the filing states the company is seeking to satisfy Nasdaq's $2.5 million stockholders' equity requirement, which remains subject to Nasdaq Hearings Panel confirmation. Following the planned conversions of the Series C Preferred Stock and Envoy's $12.5 million convertible note, BladeRanger is expected to hold a majority of Dot Ai's common stock on an as-converted basis, creating significant dilution and change-of-control implications for existing stockholders.

• · Transaction consideration was all-stock: Dot Ai common stock and Series C Convertible Preferred Stock at a $6.00 reference price.
• · Series C Preferred conversion requires Dot Ai stockholder approval to the extent required by Nasdaq rules; parties agreed to use reasonable best efforts to obtain approval by January 31, 2027, but approval was not a closing condition.
• · Envoy's $12.5M convertible note converts into Dot Ai common stock only upon stockholder approval and effectiveness of a resale registration statement, subject to certain exceptions.
• · Senior secured debt was settled and new working-capital financing completed in September 2026, preceding the closing.
• · The Company will submit evidence of Nasdaq compliance to the Nasdaq Hearings Panel; continued listing remains subject to the Panel's confirmation.
• · Transaction was approved by a Special Committee of independent directors and the Board of Directors.
• · Filing discloses a planned proxy statement with the SEC; record date to be set by the Board before mailing.

LogicMark, Inc. filed an 8-K on 2026-10-13 (AccNo 0001213900-26-109112) reporting completion of an acquisition or disposition of assets (Item 2.01), a material modification to security holder rights (Item 3.03), a change in control of the registrant (Item 5.01), director/officer departures or compensatory arrangements (Item 5.02), and bylaw/articles amendments (Item 5.03). The filing text provided is limited to item headers; no deal terms, counterparties, consideration, or financial figures are disclosed in the supplied summary.

13-10-2026

Alaunos Therapeutics (TCRT) disclosed, via an investor transaction and corporate overview presentation dated October 2026, its stock-for-stock acquisition of Velaris Therapeutics, Inc., with all Velaris equity exchanged for Alaunos common stock and non-voting Series C convertible preferred stock at a deal price of $1.4357 per common share. The transaction is paired with a concurrent $350 million private placement led by Fairmount, with proceeds intended to advance the Velaris pipeline toward proof-of-concept data and initial regulatory filings and to provide cash runway into 2029. The Velaris pipeline is entirely preclinical, with no clinical trials initiated, so the transaction carries substantial development and execution risk alongside its upside narrative.

• · Velaris is preclinical-stage with no clinical trials initiated; the presentation states no Company product candidate has been evaluated in humans
• · Pipeline milestones include IND or CTA filings for VLR199 and VLR360 in 2H27, VLR247 in 1H28, clinical start in 2027, and proof-of-concept data in 2028
• · Management risks flagged include reliance on an acting management team serving in an interim capacity, with transition to permanent roles pending
• · Dependence on Paragon Laboratories, the ninth company launched from Paragon assets, for discovery, research, manufacturing and development
• · Risk that the financing may not close on anticipated terms, and that the company will need substantial additional capital
• · No head-to-head trials exist between VLR199 and Winrevair; cross-study comparisons are not valid
• · Competitive pressure from companies developing ActRII-Fc and anti-PDGF-B therapies

Trading in its common stock (QETA), rights (QETAR) and units (QETAU) will be suspended at the open on October 14, 2026, and the company does not intend to appeal. The company states it still intends to complete its proposed business combination with Smart Kreate Group Limited and to list on Nasdaq or another national exchange, but there is no assurance of success or of a future listing.

• · Trading suspension effective at market open on October 14, 2026; Nasdaq will file a Form 25-NSE with the SEC to remove the securities from listing and registration

Starry Sea Acquisition Corp (SSEAR), a Cayman Islands SPAC, postponed its extraordinary general meeting from October 9, 2026 to October 19, 2026 to allow more time to engage with shareholders. Based on the redemption tabulation as of October 7, 2026, 4,281,993 public shares were submitted for redemption, leaving 1,468,007 public shares outstanding, and the company is seeking to reverse redemption requests on about 350,174 shares to reach at least 1,818,181 outstanding shares so the $60,000 monthly extension cap does not reduce the per-share contribution.

The Purchaser may buy up to 3,000,000 ordinary shares from public holders at no more than the approximately $10.31 per-share redemption price, with the Company funding a prepayment at closing; the agreement was amended to maximize funds retained by the Company after the combination.

• · The Registration Statement on Form S-4 (File No. 333-296926) was declared effective by the SEC on September 11, 2026.
