TDS Swings to Profit, Drops Array Buyout, Turns to Buybacks

Q2 profit swing on spectrum sales and fiber growth TDS swung to a Q2 profit of about $281 million, helped by selling wireless spectrum for cash and adding fiber customers. Management raised its 2026 fiber build target, a sign the core business is expanding. This supports the stock because profits and growth are improving.
The profit swing and raised fiber target are the main positive fundamental drivers this period.
Telecom revenue guidance cut and fiber costs rising TDS Telecom's 2026 revenue outlook was lowered and spending on fiber was increased, which could pressure margins and cash. Legacy copper and cable sales keep shrinking. This weighs on the stock because the core telecom unit is earning less while costing more to build.
It is the main counterweight to the positive earnings and explains why the stock did not simply rally.
Array buyout dropped, buybacks to restart TDS walked away from buying the rest of Array Digital with its own shares, a deal that would have diluted existing owners. Instead it will use about $524 million left in its buyback plan to repurchase stock, which can lift the share price by shrinking the number of shares.
The withdrawn dilutive deal and restart of buybacks is a clear new capital-return catalyst.
Spectrum monetization to fund fiber without dilution TDS and Array plan to speed up sales of Array's leftover wireless spectrum, turning unused assets into cash. That cash can fund TDS Telecom's fiber expansion without issuing new shares or taking on heavy debt, which supports the stock by reducing financing risk.
It explains how TDS intends to pay for growth, a key part of the period's story.

Q3 202622 Jul – 10 Sep 2026

ADTRAN Cuts Guidance, Faces Probes, but Refinances Debt

Guidance Cut and Earnings Miss ADTRAN cut Q2 revenue and margin guidance, missing consensus, and later reported Q2 revenue of $281.1M that missed its own guidance. This signals weaker-than-expected demand and execution, pushing the stock down as investors worry about future growth.
This is the core negative event that drove the stock down and remains the main overhang.
Securities Fraud Investigations Two law firms are investigating ADTRAN for potential securities fraud following the guidance cut. While no lawsuit has been filed, the probes create legal uncertainty and could lead to fines or reputational damage, weighing on the stock.
These investigations add a new layer of risk and are a direct consequence of the guidance miss.
New Credit Facility Lowers Costs ADTRAN refinanced its debt with a new senior secured credit facility led by JPMorgan, lowering borrowing costs and extending maturities. This strengthens liquidity and gives the company more flexibility to invest, a positive for the stock.
This is a concrete positive development that improves ADTRAN's financial position amid the negative news.
Optical and Cloud Sales Surge, Supply Constraints Optical networking revenue jumped 22% year over year, with cloud and hyperscaler sales nearly doubling. However, supply shortages of key components like optical amplifiers and silicon are limiting growth, and the Access segment declined. This mixed picture offers hope but also near-term headwinds.
It shows a bright spot that could drive future growth, but also highlights supply issues that are currently hurting results.
