Tenax Therapeutics’ CEO Buys Massive Option Block Amid Stock Surge, Betting on Breakthrough Pulmonary Drug.

Insider Buying at Tenax Therapeutics Signals Confidence Amid Volatility

The most recent Form 4 filing shows Tenax Therapeutics’ owner, Doogan Declan, purchasing 30,000 stock options on 2026‑01‑09 for a nominal $0.00 per share. The transaction, occurring when the stock closed at $14.70, represents a significant commitment of option equity—about 30 % of the company’s outstanding option pool. The move is noteworthy not only for its size but also for the context: Tenax’s price has surged 13.4 % in the last week and 41.9 % in the month, riding a 132 % yearly rally from a low of $4.63 last spring. Despite the lack of immediate cash flow (P/E –11.59), the option buy hints that insiders believe the company’s clinical pipeline—particularly its levosimendan‑based product for pulmonary hypertension—will generate a meaningful upside.

What This Means for Investors

Insider option purchases are often read as a bullish sign, suggesting confidence that the underlying share price will rise above the option’s exercise price. In Doogan’s case, the 30,000 options likely carry a strike near $15, close to today’s market price, implying a modest upside if the company’s upcoming Phase‑2 data are positive. The broader insider activity—Hunter Robyn’s 30,000‑share option buy and a series of large option holdings by other executives—reinforces a pattern of executive conviction. For shareholders, this could translate into a short‑term rally as the market interprets insider optimism, but the negative earnings metric and the company’s high volatility caution that any upside may be temporary or contingent on a breakthrough in the clinical program.

A Profile of Doogan Declan

Doogan has a long history of holding and buying stock options rather than purchasing common shares. Since 2022, he has acquired and maintained options in four separate tranches: 4 shares in 2022, 4 in 2023, 100,000 in 2025, and the latest 80,000 in early 2025, with a 30,000‑share purchase in 2026. His strategy appears to be “wait‑and‑see”: he holds options until a favorable market move or a clinical milestone, then exercises or sells. This pattern is consistent with a focus on capital preservation—minimizing cash outlay while positioning for upside—common among biotech executives who often face long development timelines and high upfront costs. The recent buy is the largest option tranche he has held to date, suggesting that he sees a significant catalyst on the horizon.

Insider Activity in Context

Tenax’s insider buying is not isolated. The company has seen a wave of option purchases by multiple executives—Hunter Robyn, Almenoff June, Davidson Michael, and PROEHL Geraldo—across 2025‑2026. These transactions total over 500,000 options, indicating a collective confidence in the company’s strategic direction. Meanwhile, the company’s price has reached a 52‑week high of $14.84, but earnings remain negative. The negative sentiment score (–48) and high buzz (92.37 %) suggest that social media discussions are intense but mixed, potentially amplifying short‑term price swings.

Looking Ahead

For investors, the key question is whether Tenax’s clinical program will deliver a positive data set that justifies a higher valuation. The insider option buys, particularly Doogan’s sizable purchase, imply that executives anticipate such an event. However, the company’s financials—negative P/E, limited cash, and a history of volatility—mean that any upside will need to be sustained by tangible progress in product development or strategic partnerships. Watching the next quarterly filing for clinical updates, as well as any exercise of these options, will provide the clearest signal of whether insider optimism translates into shareholder value.
