RTX urged shareholders to reject an unsolicited “mini-tender” offer from Tutanota to purchase up to 500,000 shares at $130 per share, warning that the offer is significantly below current market prices.

RTX said the offer price represents a steep discount to recent trading levels and is subject to multiple conditions, including financing. The company emphasized it is not affiliated with Tutanota and reminded investors that mini-tender offers provide fewer regulatory protections, advising shareholders to exercise caution and consult financial advisers.
