Eos Energy stock falls after Fuzzy Panda issues short report
Introduction & Market Context
CTS Corporation (NYSE:CTS) presented its third-quarter 2025 results on October 28, highlighting continued progress in its strategic shift toward diversified end markets. The company reported 8% year-over-year revenue growth to $143 million, slightly exceeding analyst expectations of $136.4 million. However, adjusted diluted earnings per share of $0.60 fell short of the forecasted $0.61, contributing to an 8.27% drop in the company’s stock price following the announcement.
The presentation emphasized CTS’s success in growing its diversified end markets, which now represent 59% of total revenue, up from 52% in the prior year. This strategic pivot comes amid persistent challenges in the transportation segment, which continues to face headwinds, particularly in commercial vehicle products.

Segment Performance Analysis
The divergent performance across CTS’s end markets illustrates the company’s ongoing transformation. Diversified end markets, comprising medical, aerospace & defense, and industrial segments, grew revenue by 22% year-over-year and now account for 59% of total revenue.
The medical segment showed strong momentum with Q3 sales of $22 million, up 22% year-over-year, and bookings increasing by 8%. The company added two customers for diagnostic ultrasound applications and received orders for therapeutics, pacemakers, and ophthalmology applications.
Similarly, the aerospace & defense segment delivered impressive results with Q3 sales of $25 million, up 23% year-over-year, and bookings surging by 29%. A significant highlight was SyQwest’s sole source award of $5 million with follow-on potential.
The following chart illustrates the growth trajectory in these key diversified markets:

The industrial segment also performed well, with Q3 sales of $37 million representing a 21% year-over-year increase and bookings up 29%. The company secured multiple wins for industrial printing, EMC, and temperature sensing applications, while adding a new customer for position sensing.
In contrast, the transportation segment continued to face challenges, with Q3 sales declining by 7% year-over-year to $59 million, primarily due to soft sales for commercial vehicle products. Despite this weakness, CTS secured a new brake sensing application award and a large extension award for actuators with a North American customer for 2028-2030 revenue.
The following chart shows the contrasting performance between the growing industrial segment and the declining transportation segment:
