Why Is Tango Therapeutics (TNGX) Down 6.2% Since Last Earnings Report?

It has been about a month since the last earnings report for Tango Therapeutics, Inc. (TNGX). Shares have lost about 6.2% in that time frame, underperforming the S&P 500.

Will the recent negative trend continue leading up to its next earnings release, or is Tango Therapeutics due for a breakout? Well, first let's take a quick look at the latest earnings report in order to get a better handle on the recent catalysts for Tango Therapeutics, Inc. before we dive into how investors and analysts have reacted as of late.

TNGX Q2 Earnings Miss Estimates on Higher Expenses

Tango incurred a loss of 37 cents per share in the second quarter of 2026, wider than the Zacks Consensus Estimate of a loss of 31 cents, as higher operating expenses weighed on the result. The company had reported a loss of 35 cents per share in the year-ago quarter. Collaboration revenues were zero compared with $3.2 million a year earlier.

TNGX's Q2 Results in Detail

In the absence of a marketed product, Tango has no recurring product revenues. The company instead reports collaboration revenues periodically, depending on the terms and progress of its collaboration arrangements.

All remaining deferred revenues from upfront and research option-extension payments under the Gilead collaboration were recognized during 2025. This followed the truncation of the collaboration agreement, which concluded all research activities. Consequently, Tango recorded no collaboration revenues in the reported quarter.

Research and development expenses increased 13% year over year to $37.2 million in the second quarter of 2026. The increase primarily reflected higher spending related to the advancement of the vopimetostat and TNG456 clinical programs. The rise was partly offset by lower spending resulting from Tango's portfolio prioritization efforts.

General and administrative expenses almost doubled year over year to $22.6 million, mainly due to higher personnel-related costs, including share-based compensation.

How Have Estimates Been Moving Since Then?

The consensus estimate has shifted -10.16% due to these changes.
