3. The investment debate
Latticework interpretation of the reported results—not the stated motives of any investor.
What could support the case
If investment in rate-regulated infrastructure continues to be reflected in approved service rates, it could support earnings growth, as recent increases were partly attributed to infrastructure investments.
Supporting filing ↗The strongest caution
Delays in regulatory approval of new customer rates could adversely affect results, financial position and liquidity.
Caution evidence ↗An interesting business is not necessarily an attractive investment at today's price. Price, dilution, financing terms and a valuation range still need investigation.
Inspect the evidence behind both sides ↗4. Three questions worth investigating
Use these to guide your research, not as conclusions that have already been proved.
How will the pending Missouri electric rate request be decided?
Starting evidence: Ameren Missouri requested higher electric revenues based on a stated return on equity, with a decision expected after an extended proceeding.
Investigate next: Compare the requested return and capital structure with recent commission decisions and intervenor positions as the case progresses.
Read the supporting filing ↗How well do mitigation mechanisms offset regulatory lag?
Starting evidence: Regulatory lag effects are mitigated by various means that differ by jurisdiction, including reconciliations, decoupling, riders and trackers.
Investigate next: Review which mechanisms apply in each jurisdiction and whether any are scheduled to expire or change.
Read the supporting filing ↗What are the execution and approval risks of new generation projects?
Starting evidence: Ameren Missouri filed to construct battery and gas projects and acquire solar projects; applications are not evidence of completed projects.
Investigate next: Track approval status, cost recovery treatment and timing of each pending project in later filings.
