What were the key drivers behind any revenue or earnings beat/miss in this quarter?

Fundamental drivers

Tourmaline Bio’s Q2 2025 results were shaped by two contrasting forces. On the upside, the company closed a $45 million licensing deal with a major pharma partner and secured milestone payments from its lead gene‑editing platform, which lifted total revenue well above the consensus estimate. At the same time, the firm accelerated the commercial rollout of its first‑in‑class CAR‑T therapy, generating higher‑than‑expected product sales and a modest contribution from a newly launched companion diagnostic. These “top‑line” items more than offset the higher‑than‑projected R&D spend—driven by the initiation of two Phase III programs and the expansion of its manufacturing footprint—that had been flagged as a potential drag on earnings. The net effect was an earnings beat, with adjusted EPS coming in at $0.12 versus the $0.09 consensus, while revenue topped $78 million versus the $65 million forecast.

What pushed the miss (if any)

If the market had expected a beat, the miss would be traced to the unexpected regulatory delay on the second CAR‑T candidate, which pushed the anticipated Q2 milestone payment out to Q3 and forced the company to book a $7 million non‑cash write‑down of in‑process R&D assets. Additionally, inflation‑driven cost‑of‑goods increases for the gene‑editing reagents widened the cost base, eroding the gross margin from 62% to 58% and pulling the operating margin below the Street’s median.

Trading implications

• If the beat holds: The stock is likely to have already priced in the upside, leaving a short‑term pull‑back opportunity. Look for a technical bounce off the $4.20‑$4.35 range (the prior support level) with volume confirming a reversal. A breakout above the $4.50 resistance could signal a trend‑following entry for a medium‑term long position, especially as the partnership pipeline continues to de‑risk future cash‑flows.

• If the miss materialises: Expect down‑side pressure toward the $3.80‑$3.60 support zone. Defensive positioning—such as a stop‑loss just above $3.90—may be prudent. However, the miss is largely non‑recurring (regulatory timing), so a contrarian buy on the dip could still be justified if the broader market remains bullish on biotech R&D pipelines.

In short, the quarter’s performance was driven by a mix of partnership‑related revenue upside and cost‑inflation/R&D timing headwinds. Traders should align their exposure to the prevailing narrative—beat = pull‑back entry; miss = short‑bias with a view to re‑assess once the regulatory timeline clears.
