3 Telecom Infrastructure Stocks On Watch After The Telstra Outage

Telstra’s nationwide mobile outage has thrown a spotlight on how critical resilient telecoms infrastructure has become for everything from emergency calls to card payments and EV charging. When a single software fault can ripple through an entire country, attention often shifts to the companies that build, maintain, and secure the underlying networks. This article looks at how that shock event connects to the Telecommunications Infrastructure and Network Equipment screener. It also highlights 3 stocks exposed to this news that the screener suggests could be positively positioned as operators reassess reliability, compliance, and risk across their systems.

Renishaw (LSE:RSW)

Overview: Renishaw is a UK engineering and scientific technology company that supplies high precision measurement, motion control, and healthcare systems used in factories, research labs, and medical settings worldwide, from aerospace and automotive production lines to neurosurgery and industrial 3D printing.

Operations: Renishaw generates revenue across multiple regions, with around £201.8 million from China, £155.0 million from the USA, £116.8 million from EMEA excluding Germany and the UK, and meaningful contributions from Japan, Germany, the UK, the rest of the Americas, and wider APAC.

Market Cap: £3.5b

Renishaw gives you exposure to the plumbing of high precision manufacturing and testing at a time when telecom outages are pushing operators to reassess how they measure and assure network performance. The company sits at the intersection of semiconductors, aerospace, and advanced factory automation, but recent earnings have declined and its high P/E and premium price relative to cash flow estimates leave little room if growth or margins underwhelm. Forecast revenue and earnings expansion, refreshed board oversight, and investment in IT and automation are positives, yet funding risk and loss making segments add complexity. For investors weighing quality engineering exposure against valuation and execution risk, Renishaw’s role in test, measurement, and process control is only part of the story.

Vishay Precision Group (VPG)

Overview: Vishay Precision Group is a US-based specialist in high accuracy sensors, weighing systems, and measurement equipment that sits behind everything from crash test dummies and steel mills to agriculture, aerospace, and robotics. Its hardware and software let customers precisely measure force, pressure, tension, and temperature so critical equipment runs safely and consistently.

Operations: Vishay Precision Group generates about US$123.4 million from Sensors, US$115.6 million from Weighing Solutions, and US$83.0 million from Measurement Systems, with a small loss reported in Corporate/Other.

Market Cap: US$1.5b

Vishay Precision Group provides targeted exposure to precision sensors and monitoring systems that telecom operators increasingly use when outages like Telstra’s lead to a rethink of network resilience. Its technology is tied into automation, robotics, automotive testing, aerospace, and data centers, which helps diversify end markets. A premium P/S multiple, reliance on external borrowing, and sensitivity to customer project timing and one-off items highlight that the path is not risk free, and the Telstra shock underlines why its execution matters.

Vishay Precision Group sits at the crossroads of automation and resilience, yet its premium P/S and project timing risk leave questions about how durable that positioning really is, which the analysis report for Vishay Precision Group

LightPath Technologies (LPTH)

Overview: LightPath Technologies designs and manufactures optical components, infrared lenses, and camera systems that control and detect light for uses such as defense and border security, medical devices, industrial tools, automotive safety, and telecommunications equipment.

Operations: LightPath Technologies generates about US$62.8 million from its Optics segment, with revenue primarily from the United States at US$31.0 million and Europe at US$25.0 million, and smaller contributions from China and other Asian markets.

Market Cap: US$787.4 million

LightPath Technologies is attracting attention because its optics and infrared systems sit directly in the path of higher resilience spending after outages like Telstra’s, particularly as telecoms and security customers upgrade surveillance, perimeter monitoring, and network equipment. The G5 Infrared acquisition positions the company to move from selling components to supplying complete systems and cameras into defense and counter drone programs. That shift brings integration and execution risk, and current operations remain loss making. Forecast revenue and earnings growth, together with recent index inclusions and fresh equity capital, indicates that expectations are high and dilution risk is present. The key consideration is how this mix of telecom exposure, security demand, and higher value products develops over the next few years.

LightPath Technologies’ shift from components to full infrared systems is accelerating interest, but the real swing factor sits inside the analyst forecasts for LightPath Technologies and how that growth story lines up with its current losses and fresh capital.
