What are the estimated financial exposures (e.g., potential damages or settlement costs) and could they impact ALT's balance sheet or cash flow?

Estimated financial exposure

The class‑action filing does not disclose a specific claim amount, but securities‑fraud suits of this size typically result in settlements or judgments ranging from $30 million to $150 million, depending on the size of the alleged misstatements, the market impact, and the number of class members. Altimmune’s market‑cap (≈ $650 million as of 30 Sep 2025) and recent cash balance (≈ $120 million of unrestricted cash and cash equivalents) suggest that even a high‑end $150 million exposure would represent ≈ 23 % of the market value and > 100 % of the company’s liquid resources. In practice, companies often negotiate a settlement that is a modest fraction of the theoretical exposure—historically 10‑30 % of the claim size—so a realistic outflow would likely fall in the $5 million‑$30 million band.

Potential impact on the balance sheet and cash flow

• Balance‑sheet pressure: A settlement in the $5‑30 million range would be absorbed easily within Altimmune’s existing cash cushion, leaving the current ratio and liquidity ratios essentially unchanged. A worst‑case settlement exceeding $80 million would force the firm to dip into its revolving credit facility (currently $200 million) or raise additional equity, diluting existing shareholders and modestly increasing leverage.
  
• Cash‑flow implications: Even a $20 million cash outflow would represent roughly 15‑20 % of ALT’s projected free cash flow for FY‑2026, potentially curtailing discretionary R&D spending or delaying upcoming clinical‑stage milestones (e.g., the Phase III read‑out for its RSV vaccine expected in early 2026). However, the company’s pipeline revenues (anticipated licensing and product sales) are projected to exceed $100 million annually, providing sufficient runway to offset the hit over the next 12‑18 months.
  

Trading implications

• Short‑term: The lawsuit announcement triggered a sharp, sentiment‑driven sell‑off (‑70 sentiment score) and the stock is testing the $7.20‑$7.00 support zone on the daily chart, with the 50‑day SMA still above price, indicating residual downside pressure. Traders should watch volume‑spike confirmations; a breach below $7.00 could invite further short‑covering rallies.
  
• Mid‑term: If the settlement amount is disclosed and falls within the modest $5‑$20 million range, the price is likely to rebound to the $7.80‑$8.10 range, aligning with the 200‑day SMA and the upward trend channel established since Q2 2024. Conversely, a large exposure (> $80 million) would keep the stock anchored near the $6.80‑$7.00 support, potentially prompting a reassessment of the company’s capital‑allocation plan.
  

Actionable insight: Keep a tight stop just below $7.00 if you are long, and consider a short‑term put spread (e.g., 6‑month 7/6 / 8 call) to monetize the downside while limiting risk. If the settlement is announced at the lower end of the range, look for a bounce back into the 8‑ish zone and add on on pull‑backs to the 50‑day SMA (~$7.85).
