Abhinav Shukla, Chief Technical Officer at Shattuck Labs, Inc. (NASDAQ: STTK), executed a sale of 410 shares on July 2, 2026, under a pre-arranged trading plan. The transaction, valued at $2,874, was facilitated by a Rule 10b5-1 plan adopted in February 2026 to cover option exercise costs and tax withholdings. The sale occurred as STTK stock traded at $7.26, near its 52-week high of $8.33, following a substantial 840% gain over the past year. Despite this recent performance, analysis indicates the stock may be overvalued relative to its fair value. Concurrently, Shukla exercised stock options to acquire 12,563 shares at an exercise price of $3.57, bringing his total direct holdings to 98,533 shares and leaving him with 14,140 unexercised options. These transactions are part of a broader grant allowing him to purchase 52,200 shares, with vesting extending through January 25, 2027, contingent on continued service. Shattuck Labs is also actively pursuing capital through a public offering expected to raise approximately $75 million, priced at $4.00 per share for 10,879,376 shares, along with pre-funded warrants for up to 7,870,624 shares. The company has also received notices to exercise approximately 50.6 million common stock warrants, which could generate gross proceeds of about $54.9 million. In clinical developments, Shattuck Labs reported positive Phase 1 results for its SL-325 DR3 blocking antibody candidate, noting a low immunogenicity profile across 72 healthy volunteers. The public offering includes an option for underwriters to purchase an additional 15% of shares, signaling strategic efforts to strengthen the company's financial position and advance its clinical programs.
