U.S. stock futures retreated Tuesday as investors adopted a cautious stance ahead of November’s employment data, a key indicator for the labor market’s health.

Here are some of Tuesday's biggest stock movers:

BIGGEST STOCK GAINERS

B. RILEY FINANCIAL (RILY [https://seekingalpha.com/symbol/RILY]) +28.5% - Shares surged primarily due to the company finally filing its overdue second-quarter 10-Q report [https://seekingalpha.com/news/4531696-b-riley-swings-to-profit-in-overdue-q2-report-stock-jumps], which revealed a massive swing back to profitability. Net income stood at $137.5M in the quarter ended June 30, 2025, compared with a -$435.6M net loss in last year's Q2. Investors are reacting positively to the company's improved balance sheet. B. Riley reduced its total debt by $314 million, bringing the total down to $1.46 billion. The filing of this report was a critical step in maintaining the company’s Nasdaq listing.

ORGANOGENESIS HOLDINGS (ORGO [https://seekingalpha.com/symbol/ORGO]) +7.5% - Shares jump following a successful "Type-B" meeting, the FDA confirmed that Organogenesis can initiate a rolling Biologics License Application [https://seekingalpha.com/pr/20340107-organogenesis-announces-successful-fda-meeting-and-plan-to-file-bla-for-renu-for-knee] (BLA) for ReNu, a treatment for knee osteoarthritis pain. The company announced it expects to start this rolling submission before the end of December 2025, significantly clarifying the path to full regulatory approval. The FDA confirmed that the existing clinical development program—which includes two large Phase 3 trials and a separate 200-patient study—is appropriate for the BLA submission.

BIGGEST STOCK LOSERS

FRACTYL HEALTH (GUTS [https://seekingalpha.com/symbol/GUTS]) -10.71% - Shares slid due to the company's decision to call its Tranche A warrants for cancellation [https://seekingalpha.com/pr/20340238-fractyl-health-announces-call-of-tranche-a-warrants-tied-to-august-2025-public-offering]. The company announced it is calling all outstanding Tranche A Common Stock Purchase Warrants to be exercised or cancelled by December 30, 2025. There are approximately 17.06 million warrants outstanding. If holders choose to exercise these at the set price of $1.05, a significant number of new shares will enter the market, leading to stock dilution. Holders who do not exercise by the deadline will see their warrants cancelled for a nominal value ($0.00001) per share underlying such Tranche A Warrant.

KYVERNA THERAPEUTICS (KYTX [https://seekingalpha.com/symbol/KYTX]) -6.7% - Shares fell due to the announcement of a $100 million public offering [https://seekingalpha.com/news/4531690-kyverna-therapeutics-announces-100m-proposed-public-offering] of its common stock (plus a $15 million underwriter option). This decline follows a volatile 24 hours where the stock initially rocketed over 25% on positive clinical data [https://seekingalpha.com/pr/20338943-kyverna-therapeutics-announces-positive-topline-data-from-registrational-kysaminus-8-trial-of] the company reported topline Phase 2 data for its CAR T-cell therapy, miv-cel, which showed significant improvement in patients with Stiff Person Syndrome (SPS), before retreating on the news of the stock sale.

READY CAPITAL (RC [https://seekingalpha.com/symbol/RC]) -9.44% - Shares down after a drastic 92% dividend cut [https://seekingalpha.com/news/4531733-ready-capital-whacks-dividend-by-92-to-001]. This is a massive drop from the $0.25–$0.30 per share levels the company had targeted in previous years and its most recent prior dividend of $0.125. “The quarter’s dividend aligns with the company’s continued commitment to strengthen the balance sheet, maintain financial flexibility, and position the business for a timely recovery in profitability,” said Thomas Capasse, Chairman and Chief Executive Officer.

LIGHTWAVE LOGIC (LWLG [https://seekingalpha.com/symbol/LWLG]) -14.59% - Shares slid due to the pricing of a $35 million public offering [https://seekingalpha.com/news/4531743-lightwave-logic-prices-35m-public-offering-boosts-cash-reserves-to-70m] of common stock via issuance of 11,666,667 shares, and granted underwriters a 30-day option to purchase up to 1.75 million additional shares. Concurrent with this offering, Lightwave Logic terminated its existing equity line of credit. Following the close (expected December 17), the company expects to have $70 million in total cash. Net proceeds from the offering will be used to accelerate commercialization and U.S. production capacity, support large-scale "design-ins," and fund potential strategic M&A, and for working capital and other general corporate purposes.
